CHAPTER III—VOLCANOS

You want to know why the Spaniards in Peru and Ecuador should have expected an earthquake.

Because they had had so many already.  The shaking of the ground in their country had gone on perpetually, till they had almost ceased to care about it, always hoping that no very heavy shock would come; and being, now and then, terribly mistaken.

For instance, in the province of Quito, in the year 1797, from thirty to forty thousand people were killed at once by an earthquake.  One would have thought that warning enough: but the warning was not taken: and now, this very year, thousands more have been killed in the very same country, in the very same way.

They might have expected as much.  For their towns are built, most of them, close to volcanos—some of the highest and most terrible in the world.  And wherever there are volcanos there will be earthquakes.  You may have earthquakes without volcanos, now and then; but volcanos without earthquakes, seldom or never.

How does that come to pass?  Does a volcano make earthquakes?  No; we may rather say that earthquakes are trying to make volcanos.  For volcanos are the holes which the steam underground has burst open that it may escape into the air above.  They are the chimneys of the great blast-furnaces underground, in which Madam How pounds and melts up the old rocks, to make them into new ones, and spread them out over the land above.

And are there many volcanos in the world?  You have heard of Vesuvius, of course, in Italy; and Etna, in Sicily; and Hecla, in Iceland.  And you have heard, too, of Kilauea, in the Sandwich Islands, and of Pele’s Hair—the yellow threads of lava, like fine spun glass, which are blown from off its pools of fire, and which the Sandwich Islanders believed to be the hair of a goddess who lived in the crater;—and you have read, too, I hope, in Miss Yonge’s Book of Golden Deeds , the noble story of the Christian chieftainess who, in order to persuade her subjects to become Christians also, went down into the crater and defied the goddess of the volcano, and came back unhurt and triumphant.

But if you look at the map, you will see that there are many, many more.  Get Keith Johnston’s Physical Atlas from the schoolroom—of course it is there (for a schoolroom without a physical atlas is like a needle without an eye)—and look at the map which is called “Phenomena of Volcanic Action.”

You will see in it many red dots, which mark the volcanos which are still burning: and black dots, which mark those which have been burning at some time or other, not very long ago, scattered about the world.  Sometimes they are single, like the red dot at Otaheite, or at Easter Island in the Pacific.  Sometimes the are in groups, or clusters, like the cluster at the Sandwich Islands, or in the Friendly Islands, or in New Zealand.  And if we look in the Atlantic, we shall see four clusters: one in poor half-destroyed Iceland, in the far north, one in the Azores, one in the Canaries, and one in the Cape de Verds.  And there is one dot in those Canaries which we must not overlook, for it is no other than the famous Peak of Teneriffe, a volcano which is hardly burnt out yet, and may burn up again any day, standing up out of the sea more than 12,000 feet high still, and once it must have been double that height.  Some think that it is perhaps the true Mount Atlas, which the old Greeks named when first they ventured out of the Straits of Gibraltar down the coast of Africa, and saw the great peak far to the westward, with the clouds cutting off its top; and said that it was a mighty giant, the brother of the Evening Star, who held up the sky upon his shoulders, in the midst of the Fortunate Islands, the gardens of the daughter of the Evening Star, full of strange golden fruits; and that Perseus had turned him into stone, when he passed him with the Gorgon’s Head.

But you will see, too, that most of these red and black dots run in crooked lines; and that many of the clusters run in lines likewise.

Look at one line: by far the largest on the earth.  You will learn a good deal of geography from it.

The red dots begin at a place called the Terribles, on the east side of the Bay of Bengal.  They run on, here and there, along the islands of Sumatra and Java, and through the Spice Islands; and at New Guinea the line of red dots forks.  One branch runs south-east, through islands whose names you never heard, to the Friendly Islands, and to New Zealand.  The other runs north, through the Philippines, through Japan, through Kamschatka; and then there is a little break of sea, between Asia and America: but beyond it, the red dots begin again in the Aleutian Islands, and then turn down the whole west coast of America, down from Mount Elias (in what was, till lately, Russian America) towards British Columbia.  Then, after a long gap, there are one or two in Lower California (and we must not forget the terrible earthquake which has just shaken San Francisco, between those two last places); and when we come down to Mexico we find the red dots again plentiful, and only too plentiful; for they mark the great volcanic line of Mexico, of which you will read, I hope, some day, in Humboldt’s works.  But the line does not stop there.  After the little gap of the Isthmus of Panama, it begins again in Quito, the very country which has just been shaken, and in which stand the huge volcanos Chimborazo, Pasto, Antisana, Cotopaxi, Pichincha, Tunguragua,—smooth cones from 15,000 to 20,000 feet high, shining white with snow, till the heat inside melts it off, and leaves the cinders of which the peaks are made all black and ugly among the clouds, ready to burst in smoke and fire.  South of them again, there is a long gap, and then another line of red dots—Arequiba, Chipicani, Gualatieri, Atacama,—as high as, or higher than those in Quito; and this, remember, is the other country which has just been shaken.  On the sea-shore below those volcanos stood the hapless city of Arica, whose ruins we saw in the picture.  Then comes another gap; and then a line of more volcanos in Chili, at the foot of which happened that fearful earthquake of 1835 (besides many more) of which you will read some day in that noble book The Voyage of the Beagle ; and so the line of dots runs down to the southernmost point of America.

What a line we have traced!  Long enough to go round the world if it were straight.  A line of holes out of which steam, and heat, and cinders, and melted stones are rushing up, perpetually, in one place and another.  Now the holes in this line which are near each other have certainly something to do with each other.  For instance, when the earth shook the other day round the volcanos of Quito, it shook also round the volcanos of Peru, though they were 600 miles away.  And there are many stories of earthquakes being felt, or awful underground thunder heard, while volcanos were breaking out hundreds of miles away.  I will give you a very curious instance of that.

If you look at the West Indies on the map, you will see a line of red dots runs through the Windward Islands: there are two volcanos in them, one in Guadaloupe, and one in St. Vincent (I will tell you a curious story, presently, about that last), and little volcanos (if they have ever been real volcanos at all), which now only send out mud, in Trinidad.  There the red dots stop: but then begins along the north coast of South America a line of mountain country called Cumana, and Caraccas, which has often been horribly shaken by earthquakes.  Now once, when the volcano in St. Vincent began to pour out a vast stream of melted lava, a noise like thunder was heard underground, over thousands of square miles beyond those mountains, in the plains of Calabozo, and on the banks of the Apure, more than 600 miles away from the volcano,—a plain sign that there was something underground which joined them together, perhaps a long crack in the earth.  Look for yourselves at the places, and you will see that (as Humboldt says) it is as strange as if an eruption of Mount Vesuvius was heard in the north of France.

So it seems as if these lines of volcanos stood along cracks in the rind of the earth, through which the melted stuff inside was for ever trying to force its way; and that, as the crack got stopped up in one place by the melted stuff cooling and hardening again into stone, it was burst in another place, and a fresh volcano made, or an old one re-opened.

Now we can understand why earthquakes should be most common round volcanos; and we can understand, too, why they would be worst before a volcano breaks out, because then the steam is trying to escape; and we can understand, too, why people who live near volcanos are glad to see them blazing and spouting, because then they have hope that the steam has found its way out, and will not make earthquakes any more for a while.  But still that is merely foolish speculation on chance.  Volcanos can never be trusted.  No one knows when one will break out, or what it will do; and those who live close to them—as the city of Naples is close to Mount Vesuvius—must not be astonished if they are blown up or swallowed up, as that great and beautiful city of Naples may be without a warning, any day.

For what happened to that same Mount Vesuvius nearly 1800 years ago, in the old Roman times?  For ages and ages it had been lying quiet, like any other hill.  Beautiful cities were built at its foot, filled with people who were as handsome, and as comfortable, and (I am afraid) as wicked, as people ever were on earth.  Fair gardens, vineyards, olive-yards, covered the mountain slopes.  It was held to be one of the Paradises of the world.  As for the mountain’s being a burning mountain, who ever thought of that?  To be sure, on the top of it was a great round crater, or cup, a mile or more across, and a few hundred yards deep.  But that was all overgrown with bushes and wild vines, full of boars and deer.  What sign of fire was there in that?  To be sure, also, there was an ugly place below by the sea-shore, called the Phlegræn fields, where smoke and brimstone came out of the ground, and a lake called Avernus over which poisonous gases hung, and which (old stories told) was one of the mouths of the Nether Pit.  But what of that?  It had never harmed any one, and how could it harm them?

So they all lived on, merrily and happily enough, till, in the year A.D. 79 (that was eight years, you know, after the Emperor Titus destroyed Jerusalem), there was stationed in the Bay of Naples a Roman admiral, called Pliny, who was also a very studious and learned man, and author of a famous old book on natural history.  He was staying on shore with his sister; and as he sat in his study she called him out to see a strange cloud which had been hanging for some time over the top of Mount Vesuvius.  It was in shape just like a pine-tree; not, of course, like one of our branching Scotch firs here, but like an Italian stone pine, with a long straight stem and a flat parasol-shaped top.  Sometimes it was blackish, sometimes spotted; and the good Admiral Pliny, who was always curious about natural science, ordered his cutter and went away across the bay to see what it could be.  Earthquake shocks had been very common for the last few days; but I do not suppose that Pliny had any notion that the earthquakes and the cloud had aught to do with each other.  However, he soon found out that they had, and to his cost.  When he got near the opposite shore some of the sailors met him and entreated him to turn back.  Cinders and pumice-stones were falling down from the sky, and flames breaking out of the mountain above.  But Pliny would go on: he said that if people were in danger, it was his duty to help them; and that he must see this strange cloud, and note down the different shapes into which it changed.  But the hot ashes fell faster and faster; the sea ebbed out suddenly, and left them nearly dry, and Pliny turned away to a place called Stabiæ, to the house of his friend Pomponianus, who was just going to escape in a boat.  Brave Pliny told him not to be afraid, ordered his bath like a true Roman gentleman, and then went into dinner with a cheerful face.  Flames came down from the mountain, nearer and nearer as the night drew on; but Pliny persuaded his friend that they were only fires in some villages from which the peasants had fled, and then went to bed and slept soundly.  However, in the middle of the night they found the courtyard being fast filled with cinders, and, if they had not woke up the Admiral in time, he would never have been able to get out of the house.  The earthquake shocks grew stronger and fiercer, till the house was ready to fall; and Pliny and his friend, and the sailors and the slaves, all fled into the open fields, amid a shower of stones and cinders, tying pillows over their heads to prevent their being beaten down.  The day had come by this time, but not the dawn—for it was still pitch dark as night.  They went down to their boats upon the shore; but the sea raged so horribly that there was no getting on board of them.  Then Pliny grew tired, and made his men spread a sail for him, and lay down on it; but there came down upon them a rush of flames, and a horrible smell of sulphur, and all ran for their lives.  Some of the slaves tried to help the Admiral upon his legs; but he sank down again overpowered with the brimstone fumes, and so was left behind.  When they came back again, there he lay dead, but with his clothes in order and his face as quiet as if he had been only sleeping.  And that was the end of a brave and learned man—a martyr to duty and to the love of science.

But what was going on in the meantime?  Under clouds of ashes, cinders, mud, lava, three of those happy cities were buried at once—Herculaneum, Pompeii, Stabiæ.  They were buried just as the people had fled from them, leaving the furniture and the earthenware, often even jewels and gold, behind, and here and there among them a human being who had not had time to escape from the dreadful deluge of dust.  The ruins of Herculaneum and Pompeii have been dug into since; and the paintings, especially in Pompeii, are found upon the walls still fresh, preserved from the air by the ashes which have covered them in.  When you are older you perhaps will go to Naples, and see in its famous museum the curiosities which have been dug out of the ruined cities; and you will walk, I suppose, along the streets of Pompeii and see the wheel-tracks in the pavement, along which carts and chariots rumbled 2000 years ago.  Meanwhile, if you go nearer home, to the Crystal Palace and to the Pompeian Court, as it is called, you will see an exact model of one of these old buried houses, copied even to the very paintings on the wells, and judge for yourself, as far as a little boy can judge, what sort of life these thoughtless, luckless people lived 2000 years ago.

And what had become of Vesuvius, the treacherous mountain?  Half or more than half of the side of the old crater had been blown away, and what was left, which is now called the Monte Somma, stands in a half circle round the new cone and new crater which is burning at this very day.  True, after that eruption which killed Pliny, Vesuvius fell asleep again, and did not awake for 134 years, and then again for 269 years but it has been growing more and more restless as the ages have passed on, and now hardly a year passes without its sending out smoke and stones from its crater, and streams of lava from its sides.

And now, I suppose, you will want to know what a volcano is like, and what a cone, and a crater, and lava are?

What a volcano is like, it is easy enough to show you; for they are the most simply and beautifully shaped of all mountains, and they are alike all over the world, whether they be large or small.  Almost every volcano in the world, I believe, is, or has been once, of the shape which you see in the drawing opposite; even those volcanos in the Sandwich Islands, of which you have often heard, which are now great lakes of boiling fire upon flat downs, without any cone to them at all.  They, I believe, are volcanos which have fallen in ages ago: just as in Java a whole burning mountain fell in on the night of the 11th of August, in the year 1772.  Then, after a short and terrible earthquake, a bright cloud suddenly covered the whole mountain.  The people who dwelt around it tried to escape; but before the poor souls could get away the earth sunk beneath their feet, and the whole mountain fell in and was swallowed up with a noise as if great cannon were being fired.  Forty villages and nearly 3000 people were destroyed, and where the mountain had been was only a plain of red-hot stones.  In the same way, in the year 1698, the top of a mountain in Quito fell in in a single night, leaving only two immense peaks of rock behind, and pouring out great floods of mud mixed with dead fish; for there are underground lakes among those volcanos which swarm with little fish which never see the light.

But most volcanos as I say, are, or have been, the shape of the one which you see here.  This is Cotopaxi, in Quito, more than 19,000 feet in height.  All those sloping sides are made of cinders and ashes, braced together, I suppose, by bars of solid lava-stone inside, which prevent the whole from crumbling down.  The upper part, you see, is white with snow, as far down as a line which is 15,000 feet above the sea; for the mountain is in the tropics, close to the equator, and the snow will not lie in that hot climate any lower down.  But now and then the snow melts off and rushes down the mountain side in floods of water and of mud, and the cindery cone of Cotopaxi stands out black and dreadful against the clear blue sky, and then the people of that country know what is coming.  The mountain is growing so hot inside that it melts off its snowy covering; and soon it will burst forth with smoke and steam, and red-hot stones and earthquakes, which will shake the ground, and roars that will be heard, it may be, hundreds of miles away.

And now for the words cone, crater, lava.  If I can make you understand those words, you will see why volcanos must be in general of the shape of Cotopaxi.

Cone, crater, lava: those words make up the alphabet of volcano learning.  The cone is the outside of a huge chimney; the crater is the mouth of it.  The lava is the ore which is being melted in the furnace below, that it may flow out over the surface of the old land, and make new land instead.

And where is the furnace itself?  Who can tell that?  Under the roots of the mountains, under the depths of the sea; down “the path which no fowl knoweth, and which the vulture’s eye hath not seen: the lion’s whelp hath not trodden it, nor the fierce lion passed by it.  There He putteth forth His hand upon the rock; He overturneth the mountain by the roots; He cutteth out rivers among the rocks; and His eye seeth every precious thing”—while we, like little ants, run up and down outside the earth, scratching, like ants, a few feet down, and calling that a deep ravine; or peeping a few feet down into the crater of a volcano, unable to guess what precious things may lie below—below even the fire which blazes and roars up through the thin crust of the earth.  For of the inside of this earth we know nothing whatsoever: we only know that it is, on an average, several times as heavy as solid rock; but how that can be, we know not.

So let us look at the chimney, and what comes out of it; for we can see very little more.

Why is a volcano like a cone?

For the same cause for which a molehill is like a cone, though a very rough one; and that the little heaps which the burrowing beetles make on the moor, or which the ant-lions in France make in the sand, are all something in the shape of a cone, with a hole like a crater in the middle.  What the beetle and the ant-lion do on a very little scale, the steam inside the earth does on a great scale.  When once it has forced a vent into the outside air, it tears out the rocks underground, grinds them small against each other, often into the finest dust, and blasts them out of the hole which it has made.  Some of them fall back into the hole, and are shot out again: but most of them fall round the hole, most of them close to it, and fewer of them farther off, till they are piled up in a ring round it, just as the sand is piled up round a beetle’s burrow.  For days, and weeks, and months this goes on; even it may be for hundreds of years: till a great cone is formed round the steam vent, hundreds or thousands of feet in height, of dust and stones, and of cinders likewise.  For recollect, that when the steam has blown away the cold earth and rock near the surface of the ground, it begins blowing out the hot rocks down below, red-hot, white-hot, and at last actually melted.  But these, as they are hurled into the cool air above, become ashes, cinders, and blocks of stone again, making the hill on which they fall bigger and bigger continually.  And thus does wise Madam How stand in no need of bricklayers, but makes her chimneys build themselves.

And why is the mouth of the chimney called a crater?

Crater, as you know, is Greek for a cup.  And the mouth of these chimneys, when they have become choked and stopped working, are often just the shape of a cup, or (as the Germans call them) kessels, which means kettles, or caldrons.  I have seen some of them as beautifully and exactly rounded as if a cunning engineer had planned them, and had them dug out with the spade.  At first, of course, their sides and bottom are nothing but loose stones, cinders, slag, ashes, such as would be thrown out of a furnace.  But Madam How, who, whenever she makes an ugly desolate place, always tries to cover over its ugliness, and set something green to grow over it, and make it pretty once more, does so often and often by her worn-out craters.  I have seen them covered with short sweet turf, like so many chalk downs.  I have seen them, too, filled with bushes, which held woodcocks and wild boars.  Once I came on a beautiful round crater on the top of a mountain, which was filled at the bottom with a splendid crop of potatoes.  Though Madam How had not put them there herself, she had at least taught the honest Germans to put them there.  And often Madam How turns her worn-out craters into beautiful lakes.  There are many such crater-lakes in Italy, as you will see if ever you go there; as you may see in English galleries painted by Wilson, a famous artist who died before you were born.  You recollect Lord Macaulay’s ballad, “The Battle of the Lake Regillus”?  Then that Lake Regillus (if I recollect right) is one of these round crater lakes.  Many such deep clear blue lakes have I seen in the Eifel, in Germany; and many a curious plant have I picked on their shores, where once the steam blasted, and the earthquake roared, and the ash-clouds rushed up high into the heaven, and buried all the land around in dust, which is now fertile soil.  And long did I puzzle to find out why the water stood in some craters, while others, within a mile of them perhaps, were perfectly dry.  That I never found out for myself.  But learned men tell me that the ashes which fall back into the crater, if the bottom of it be wet from rain, will sometimes “set” (as it is called) into a hard cement; and so make the bottom of the great bowl waterproof, as if it were made of earthenware.

But what gives the craters this cup-shape at first?

Think—While the steam and stones are being blown out, the crater is an open funnel, with more or less upright walls inside.  As the steam grows weaker, fewer and fewer stones fall outside, and more and more fall back again inside.  At last they quite choke up the bottom of the great round hole.  Perhaps, too, the lava or melted rock underneath cools and grows hard, and that chokes up the hole lower down.  Then, down from the round edge of the crater the stones and cinders roll inward more and more.  The rains wash them down, the wind blows them down.  They roll to the middle, and meet each other, and stop.  And so gradually the steep funnel becomes a round cup.  You may prove for yourself that it must be so, if you will try.  Do you not know that if you dig a round hole in the ground, and leave it to crumble in, it is sure to become cup-shaped at last, though at first its sides may have been quite upright, like those of a bucket?  If you do not know, get a trowel and make your little experiment.

And now you ought to understand what “cone” and “crater” mean.  And more, if you will think for yourself, you may guess what would come out of a volcano when it broke out “in an eruption,” as it is usually called.  First, clouds of steam and dust (what you would call smoke); then volleys of stones, some cool, some burning hot; and at the last, because it lies lowest of all, the melted rock itself, which is called lava.

And where would that come out?  At the top of the chimney?  At the top of the cone?

No.  Madam How, as I told you, usually makes things make themselves.  She has made the chimney of the furnace make itself; and next she will make the furnace-door make itself.

The melted lava rises in the crater—the funnel inside the cone—but it never gets to the top.  It is so enormously heavy that the sides of the cone cannot bear its weight, and give way low down.  And then, through ashes and cinders, the melted lava burrows out, twisting and twirling like an enormous fiery earth-worm, till it gets to the air outside, and runs off down the mountain in a stream of fire.  And so you may see (as are to be seen on Vesuvius now) two eruptions at once—one of burning stones above, and one of melted lava below.

And what is lava?

That, I think, I must tell you another time.  For when I speak of it I shall have to tell you more about Madam How, and her ways of making the ground on which you stand, than I can say just now.  But if you want to know (as I dare say you do) what the eruption of a volcano is like, you may read what follows.  I did not see it happen; for I never had the good fortune of seeing a mountain burning, though I have seen many and many a one which has been burnt—extinct volcanos, as they are called.

The man who saw it—a very good friend of mine, and a very good man of science also—went last year to see an eruption on Vesuvius, not from the main crater, but from a small one which had risen up suddenly on the outside of it; and he gave me leave (when I told him that I was writing for children) to tell them what he saw.

This new cone, he said, was about 200 feet high, and perhaps 80 or 100 feet across at the top.  And as he stood below it (it was not safe to go up it) smoke rolled up from its top, “rosy pink below,” from the glare of the caldron, and above “faint greenish or blueish silver of indescribable beauty, from the light of the moon.”  But more—By good chance, the cone began to send out, not smoke only, but brilliant burning stones.  “Each explosion,” he says, “was like a vast girandole of rockets, with a noise (such as rockets would make) like the waves on a beach, or the wind blowing through shrouds.  The mountain was trembling the whole time.  So it went on for two hours and more; sometimes eight or ten explosions in a minute, and more than 1000 stones in each, some as large as two bricks end to end.  The largest ones mostly fell back into the crater; but the smaller ones being thrown higher, and more acted on by the wind, fell in immense numbers on the leeward slope of the cone” (of course, making it bigger and bigger, as I have explained already to you), and of course, as they were intensely hot and bright, making the cone look as if it too was red-hot.  But it was not so, he says, really.  The colour of the stones was rather “golden, and they spotted the black cone over with their golden showers, the smaller ones stopping still, the bigger ones rolling down, and jumping along just like hares.”  “A wonderful pedestal,” he says, “for the explosion which surmounted it.”  How high the stones flew up he could not tell.  “There was generally one which went much higher than the rest, and pierced upwards towards the moon, who looked calmly down, mocking such vain attempts to reach her.”  The large stones, of course, did not rise so high; and some, he says, “only just appeared over the rim of the cone, above which they came floating leisurely up, to show their brilliant forms and intense white light for an instant, and then subside again.”

Try and picture that to yourselves, remembering that this was only a little side eruption, of no more importance to the whole mountain than the fall of a slate off the roof is of importance to the whole house.  And then think how mean and weak man’s fireworks, and even man’s heaviest artillery, are compared with the terrible beauty and terrible strength of Madam How’s artillery underneath our feet.

Now look at this figure.  It represents a section of a volcano; that is, one cut in half to show you the inside.  A is the cone of cinders.  B, the black line up through the middle, is the funnel, or crack, through which steam, ashes, lava, and everything else rises.  C is the crater mouth.  D D D, which looks broken, are the old rocks which the steam heaved up and burst before it could get out.  And what are the black lines across, marked E E E?  They are the streams of lava which have burrowed out, some covered up again in cinders, some lying bare in the open air, some still inside the cone, bracing it together, holding it up.  Something like this is the inside of a volcano.

CHAPTER IV—THE TRANSFORMATIONS OF A GRAIN OF SOIL

Why, you ask, are there such terrible things as volcanos?  Of what use can they be?

They are of use enough, my child; and of many more uses, doubt not, than we know as yet, or ever shall know.  But of one of their uses I can tell you.

They make, or help to make, divers and sundry curious things, from gunpowder to your body and mine.

What?  I can understand their helping to make gunpowder, because the sulphur in it is often found round volcanos; and I know the story of the brave Spaniard who, when his fellows wanted materials for gunpowder, had himself lowered in a basket down the crater of a South American volcano, and gathered sulphur for them off the burning cliffs: but how can volcanos help to make me?  Am I made of lava?  Or is there lava in me?

My child, I did not say that volcanos helped to make you.  I said that they helped to make your body; which is a very different matter, as I beg you to remember, now and always.  Your body is no more you yourself than the hoop which you trundle, or the pony which you ride.  It is, like them, your servant, your tool, your instrument, your organ, with which you work: and a very useful, trusty, cunningly-contrived organ it is; and therefore I advise you to make good use of it, for you are responsible for it.  But you yourself are not your body, or your brain, but something else, which we call your soul, your spirit, your life.  And that “you yourself” would remain just the same if it were taken out of your body, and put into the body of a bee, or of a lion, or any other body; or into no body at all.  At least so I believe; and so, I am happy to say, nine hundred and ninety-nine thousand nine hundred and ninety-nine people out of every million have always believed, because they have used their human instincts and their common sense, and have obeyed (without knowing it) the warning of a great and good philosopher called Herder, that “The organ is in no case the power which works by it;” which is as much as to say, that the engine is not the engine-driver, nor the spade the gardener.

There have always been, and always will be, a few people who cannot see that.  They think that a man’s soul is part of his body, and that he himself is not one thing, but a great number of things.  They think that his mind and character are only made up of all the thoughts, and feelings, and recollections which have passed through his brain; and that as his brain changes, he himself must change, and become another person, and then another person again, continually.  But do you not agree with them: but keep in mind wise Herder’s warning that you are not to “confound the organ with the power,” or the engine with the driver, or your body with yourself: and then we will go on and consider how a volcano, and the lava which flows from it, helps to make your body.

Now I know that the Scotch have a saying, “That you cannot make broth out of whinstones” (which is their name for lava).  But, though they are very clever people, they are wrong there.  I never saw any broth in Scotland, as far as I know, but what whinstones had gone to the making of it; nor a Scotch boy who had not eaten many a bit of whinstone, and been all the better for it.

Of course, if you simply put the whinstones into a kettle and boiled them, you would not get much out of them by such rough cookery as that.  But Madam How is the best and most delicate of all cooks; and she knows how to pound, and soak, and stew whinstones so delicately, that she can make them sauce and seasoning for meat, vegetables, puddings, and almost everything that you eat; and can put into your veins things which were spouted up red-hot by volcanos, ages and ages since, perhaps at the bottom of ancient seas which are now firm dry land.

This is very strange—as all Madam How’s doings are.  And you would think it stranger still if you had ever seen the flowing of a lava stream.

Out of a cave of slag and cinders in the black hillside rushes a golden river, flowing like honey, and yet so tough that you cannot thrust a stick into it, and so heavy that great stones (if you throw them on it) float on the top, and are carried down like corks on water.  It is so hot that you cannot stand near it more than a few seconds; hotter, perhaps, than any fire you ever saw: but as it flows, the outside of it cools in the cool air, and gets covered with slag and cinders, something like those which you may see thrown out of the furnaces in the Black Country of Staffordshire.  Sometimes these cling together above the lava stream, and make a tunnel, through the cracks in which you may see the fiery river rushing and roaring down below.  But mostly they are kept broken and apart, and roll and slide over each other on the top of the lava, crashing and clanging as they grind together with a horrid noise.  Of course that stream, like all streams, runs towards the lower grounds.  It slides down glens, and fills them up; down the beds of streams, driving off the water in hissing steam; and sometimes (as it did in Iceland a few years ago) falls over some cliff, turning what had been a water-fall into a fire-fall, and filling up the pool below with blocks of lava suddenly cooled, with a clang and roar like that of chains shaken or brazen vessels beaten, which is heard miles and miles away.  Of course, woe to the crops and gardens which stand in its way.  It crawls over them all and eats them up.  It shoves down houses; it sets woods on fire, and sends the steam and gas out of the tree-trunks hissing into the air.  And (curiously enough) it does this often without touching the trees themselves.  It flows round the trunks (it did so in a wood in the Sandwich Islands a few years ago), and of course sets them on fire by its heat, till nothing is left of them but blackened posts.  But the moisture which comes out of the poor tree in steam blows so hard against the lava round that it can never touch the tree, and a round hole is left in the middle of the lava where the tree was.  Sometimes, too, the lava will spit out liquid fire among the branches of the trees, which hangs down afterwards from them in tassels of slag, and yet, by the very same means, the steam in the branches will prevent the liquid fire burning them off, or doing anything but just scorch the bark.

But I can tell you a more curious story still.  The lava stream, you must know, is continually sending out little jets of gas and steam: some of it it may have brought up from the very inside of the earth; most of it, I suspect, comes from the damp herbage and damp soil over which it runs.  Be that as it may, a lava stream out of Mount Etna, in Sicily, came once down straight upon the town of Catania.  Everybody thought that the town would be swallowed up; and the poor people there (who knew no better) began to pray to St. Agatha—a famous saint, who, they say, was martyred there ages ago—and who, they fancy, has power in heaven to save them from the lava stream.  And really what happened was enough to make ignorant people, such as they were, think that St. Agatha had saved them.  The lava stream came straight down upon the town wall.  Another foot, and it would have touched it, and have begun shoving it down with a force compared with which all the battering-rams that you ever read of in ancient histories would be child’s toys.  But lo and behold! when the lava stream got within a few inches of the wall it stopped, and began to rear itself upright and build itself into a wall beside the wall.  It rose and rose, till I believe in one place it overtopped the wall and began to curl over in a crest.  All expected that it would fall over into the town at last: but no, there it stopped, and cooled, and hardened, and left the town unhurt.  All the inhabitants said, of course, that St. Agatha had done it: but learned men found out that, as usual Madam How had done it, by making it do itself.  The lava was so full of gas, which was continually blowing out in little jets, that when it reached the wall, it actually blew itself back from the wall; and, as the wall was luckily strong enough not to be blown down, the lava kept blowing itself back till it had time to cool.  And so, my dear child, there was no miracle at all in the matter; and the poor people of Catania had to thank not St. Agatha, and any interference of hers, but simply Him who can preserve, just as He can destroy, by those laws of nature which are the breath of His mouth and the servants of His will.

But in many a case the lava does not stop.  It rolls on and on over the downs and through the valleys, till it reaches the sea-shore, as it did in Hawaii in the Sandwich Islands this very year.  And then it cools, of course; but often not before it has killed the fish by its sulphurous gases and heat, perhaps for miles around.  And there is good reason to believe that the fossil fish which we so often find in rocks, perfect in every bone, lying sometimes in heaps, and twisted (as I have seen them) as if they had died suddenly and violently, were killed in this very way, either by heat from lava streams, or else by the bursting up of gases poisoning the water, in earthquakes and eruptions in the bottom of the sea.  I could tell you many stories of fish being killed in thousands by earthquakes and volcanos during the last few years.  But we have not time to tell about everything.

And now you will ask me, with more astonishment than ever, what possible use can there be in these destroying streams of fire?  And certainly, if you had ever seen a lava stream even when cool, and looked down, as I have done, at the great river of rough black blocks streaming away far and wide over the land, you would think it the most hideous and the most useless thing you ever saw.  And yet, my dear child, there is One who told men to judge not according to the appearance, but to judge righteous judgment.  He said that about matters spiritual and human: but it is quite as true about matters natural, which also are His work, and all obey His will.

Now if you had seen, as I have seen, close round the edges of these lava streams, and sometimes actually upon them, or upon the great bed of dust and ashes which have been hurled far and wide out of ancient volcanos, happy homesteads, rich crops, hemp and flax, and wheat, tobacco, lucerne, roots, and vineyards laden with white and purple grapes, you would have begun to suspect that the lava streams were not, after all, such very bad neighbours.  And when I tell you that volcanic soils (as they are called), that is, soil which has at first been lava or ashes, are generally the richest soils in the world—that, for instance (as some one told me the other day), there is soil in the beautiful island of Madeira so thin that you cannot dig more than two or three inches down without coming to the solid rock of lava, or what is harder even, obsidian (which is the black glass which volcanos sometimes make, and which the old Mexicans used to chip into swords and arrows, because they had no steel)—and that this soil, thin as it is, is yet so fertile, that in it used to be grown the grapes of which the famous Madeira wine was made—when you remember this, and when you remember, too, the Lothians of Scotland (about which I shall have to say a little to you just now), then you will perhaps agree with me, that Lady Why has not been so very wrong in setting Madam How to pour out lava and ashes upon the surface of the earth.

For see—down below, under the roots of the mountains, Madam How works continually like a chemist in his laboratory, melting together all the rocks, which are the bones and leavings of the old worlds.  If they stayed down below there, they would be of no use; while they will be of use up here in the open air.  For, year by year—by the washing of rain and rivers, and also, I am sorry to say, by the ignorant and foolish waste of mankind—thousands and millions of tons of good stuff are running into the sea every year, which would, if it could be kept on land, make food for men and animals, plants and trees.  So, in order to supply the continual waste of this upper world, Madam How is continually melting up the under world, and pouring it out of the volcanos like manure, to renew the face of the earth.  In these lava rocks and ashes which she sends up there are certain substances, without which men cannot live—without which a stalk of corn or grass cannot grow.  Without potash, without magnesia, both of which are in your veins and mine—without silicates (as they are called), which give flint to the stems of corn and of grass, and so make them stiff and hard, and able to stand upright—and very probably without the carbonic acid gas, which comes out of the volcanos, and is taken up by the leaves of plants, and turned by Madam How’s cookery into solid wood—without all these things, and I suspect without a great many more things which come out of volcanos—I do not see how this beautiful green world could get on at all.

Of course, when the lava first cools on the surface of the ground it is hard enough, and therefore barren enough.  But Madam How sets to work upon it at once, with that delicate little water-spade of hers, which we call rain, and with that alone, century after century, and age after age, she digs the lava stream down, atom by atom, and silts it over the country round in rich manure.  So that if Madam How has been a rough and hasty workwoman in pumping her treasures up out of her mine with her great steam-pumps, she shows herself delicate and tender and kindly enough in giving them away afterwards.

Nay, even the fine dust which is sometimes blown out of volcanos is useful to countries far away.  So light it is, that it rises into the sky and is wafted by the wind across the seas.  So, in the year 1783, ashes from the Skaptar Jokull, in Iceland, were carried over the north of Scotland, and even into Holland, hundreds of miles to the south.

So, again, when in the year 1812 the volcano of St. Vincent, in the West India Islands, poured out torrents of lava, after mighty earthquakes which shook all that part of the world, a strange thing happened (about which I have often heard from those who saw it) in the island of Barbados, several hundred miles away.  For when the sun rose in the morning (it was a Sunday morning), the sky remained more dark than any night, and all the poor negroes crowded terrified out of their houses into the streets, fancying the end of the world was come.  But a learned man who was there, finding that, though the sun was risen, it was still pitchy dark, opened his window, and found that it was stuck fast by something on the ledge outside, and, when he thrust it open, found the ledge covered deep in soft red dust; and he instantly said, like a wise man as he was, “The volcano of St. Vincent must have broken out, and these are the ashes from it.”  Then he ran down stairs and quieted the poor negroes, telling them not to be afraid, for the end of the world was not coming just yet.  But still the dust went on falling till the whole island, I am told, was covered an inch thick; and the same thing happened in the other islands round.  People thought—and they had reason to think from what had often happened elsewhere—that though the dust might hurt the crops for that year, it would make them richer in years to come, because it would act as manure upon the soil; and so it did after a few years; but it did terrible damage at the time, breaking off the boughs of trees and covering up the crops; and in St. Vincent itself whole estates were ruined.  It was a frightful day, but I know well that behind that How there was a Why for its happening, and happening too, about that very time, which all who know the history of negro slavery in the West Indies can guess for themselves, and confess, I hope, that in this case, as in all others, when Lady Why seems most severe she is often most just and kind.

Ah! my dear child, that I could go on talking to you of this for hours and days!  But I have time now only to teach you the alphabet of these matters—and, indeed, I know little more than the alphabet myself; but if the very letters of Madam How’s book, and the mere A, B, AB, of it, which I am trying to teach you, are so wonderful and so beautiful, what must its sentences be and its chapters?  And what must the whole book be like?  But that last none can read save He who wrote it before the worlds were made.

But now I see you want to ask a question.  Let us have it out.  I would sooner answer one question of yours than tell you ten things without your asking.

Is there potash and magnesia and silicates in the soil here?  And if there is, where did they come from?  For there are no volcanos in England.

Yes.  There are such things in the soil; and little enough of them, as the farmers here know too well.  For we here, in Windsor Forest, are on the very poorest and almost the newest soil in England; and when Madam How had used up all her good materials in making the rest of the island, she carted away her dry rubbish and shot it down here for us to make the best of; and I do not think that we and our forefathers have done so very ill with it.  But where the rich part, or staple, of our soils came from first it would be very difficult to say, so often has Madam How made, and unmade, and re-made England, and sifted her materials afresh every time.  But if you go to the Lowlands of Scotland, you may soon see where the staple of the soil came from there, and that I was right in saying that there were atoms of lava in every Scotch boy’s broth.  Not that there were ever (as far as I know) volcanos in Scotland or in England.  Madam How has more than one string to her bow, or two strings either; so when she pours out her lavas, she does not always pour them out in the open air.  Sometimes she pours them out at the bottom of the sea, as she did in the north of Ireland and the south-west of Scotland, when she made the Giant’s Causeway, and Fingal’s Cave in Staffa too, at the bottom of the old chalk ocean, ages and ages since.  Sometimes she squirts them out between the layers of rock, or into cracks which the earthquakes have made, in what are called trap dykes, of which there are plenty to be seen in Scotland, and in Wales likewise.  And then she lifts the earth up from the bottom of the sea, and sets the rain to wash away all the soft rocks, till the hard lava stands out in great hills upon the surface of the ground.  Then the rain begins eating away those lava-hills likewise, and manuring the earth with them; and wherever those lava-hills stand up, whether great or small, there is pretty sure to be rich land around them.  If you look at the Geological Map of England and Ireland, and the red spots upon it, which will show you where those old lavas are, you will see how much of them there is in England, at the Lizard Point in Cornwall, and how much more in Scotland and the north of Ireland.  In South Devon, in Shropshire—with its beautiful Wrekin, and Caradoc, and Lawley—in Wales, round Snowdon (where some of the soil is very rich), and, above all, in the Lowlands of Scotland, you see these red marks, showing the old lavas, which are always fertile, except the poor old granite, which is of little use save to cut into building stone, because it is too full of quartz—that is, flint.

Think of this the next time you go through Scotland in the railway, especially when you get near Edinburgh.  As you run through the Lothians, with their noble crops of corn, and roots, and grasses—and their great homesteads, each with its engine chimney, which makes steam do the work of men—you will see rising out of the plain, hills of dark rock, sometimes in single knobs, like Berwick Law or Stirling Crag—sometimes in noble ranges, like Arthur’s Seat, or the Sidlaws, or the Ochils.  Think what these black bare lumps of whinstone are, and what they do.  Remember they are mines—not gold mines, but something richer still—food mines, which Madam How thrust into the inside of the earth, ages and ages since, as molten lava rock, and then cooled them and lifted them up, and pared them away with her ice-plough and her rain-spade, and spread the stuff of them over the wide carses round, to make in that bleak northern climate, which once carried nothing but fir-trees and heather, a soil fit to feed a great people; to cultivate in them industry, and science, and valiant self-dependence and self-help; and to gather round the Heart of Midlothian and the Castle Rock of Edinburgh the stoutest and the ablest little nation which Lady Why has made since she made the Greeks who fought at Salamis.

Of those Greeks you have read, or ought to read, in Mr. Cox’s Tales of the Persian War .  Some day you will read of them in their own books, written in their grand old tongue.  Remember that Lady Why made them, as she has made the Scotch, by first preparing a country for them, which would call out all their courage and their skill; and then by giving them the courage and the skill to make use of the land where she had put them.

And now think what a wonderful fairy tale you might write for yourself—and every word of it true—of the adventures of one atom of Potash or some other Salt, no bigger than a needle’s point, in such a lava stream as I have been telling of.  How it has run round and round, and will run round age after age, in an endless chain of change.  How it began by being molten fire underground, how then it became part of a hard cold rock, lifted up into a cliff, beaten upon by rain and storm, and washed down into the soil of the plain, till, perhaps, the little atom of mineral met with the rootlet of some great tree, and was taken up into its sap in spring, through tiny veins, and hardened the next year into a piece of solid wood.  And then how that tree was cut down, and its logs, it may be, burnt upon the hearth, till the little atom of mineral lay among the wood-ashes, and was shovelled out and thrown upon the field and washed into the soil again, and taken up by the roots of a clover plant, and became an atom of vegetable matter once more.  And then how, perhaps, a rabbit came by, and ate the clover, and the grain of mineral became part of the rabbit; and then how a hawk killed that rabbit, and ate it, and so the grain became part of the hawk; and how the farmer shot the hawk, and it fell perchance into a stream, and was carried down into the sea; and when its body decayed, the little grain sank through the water, and was mingled with the mud at the bottom of the sea.  But do its wanderings stop there?  Not so, my child.  Nothing upon this earth, as I told you once before, continues in one stay.  That grain of mineral might stay at the bottom of the sea a thousand or ten thousand years, and yet the time would come when Madam How would set to work on it again.  Slowly, perhaps, she would sink that mud so deep, and cover it up with so many fresh beds of mud, or sand, or lime, that under the heavy weight, and perhaps, too, under the heat of the inside of the earth, that Mud would slowly change to hard Slate Rock; and ages after, it may be, Madam How might melt that Slate Rock once more, and blast it out; and then through the mouth of a volcano the little grain of mineral might rise into the open air again to make fresh soil, as it had done thousands of years before.  For Madam How can manufacture many different things out of the same materials.  She may have so wrought with that grain of mineral, that she may have formed it into part of a precious stone, and men may dig it out of the rock, or pick it up in the river-bed, and polish it, and set it, and wear it.  Think of that—that in the jewels which your mother or your sisters wear, or in your father’s signet ring, there may be atoms which were part of a live plant, or a live animal, millions of years ago, and may be parts of a live plant or a live animal millions of years hence.

Think over again, and learn by heart, the links of this endless chain of change: Fire turned into Stone—Stone into Soil—Soil into Plant—Plant into Animal—Animal into Soil—Soil into Stone—Stone into Fire again—and then Fire into Stone again, and the old thing run round once more.

So it is, and so it must be.  For all things which are born in Time must change in Time, and die in Time, till that Last Day of this our little earth, in which,

“Like to the baseless fabric of a vision,
The cloud-capped towers, the gorgeous palaces,
The solemn temples, the great globe itself,
Yea, all things which inherit, shall dissolve,
And, like an unsubstantial pageant faded,
Leave not a rack behind.”

So all things change and die, and so your body too must change and die—but not yourself.  Madam How made your body; and she must unmake it again, as she unmakes all her works in Time and Space; but you, child, your Soul, and Life, and Self, she did not make; and over you she has no power.  For you were not, like your body, created in Time and Space; and you will endure though Time and Space should be no more: because you are the child of the Living God, who gives to each thing its own body, and can give you another body, even as seems good to Him.
