"'Cross that melted rock?' my friends cried out. 'We should sink into it and be burned alive.'

"But as we stood talking great stones were thrown out of the volcano. They rolled down the mountainside close to us. If they had struck us it would have been death. There was only one way to save ourselves. I covered my face with my hat and rushed across the stream of lava. The melted rock was so thick and heavy that I did not sink in. I only burned my boots and scorched my hands. My friends followed me. On that side we were safe. We climbed for half an hour. Then we came to the head of our red river. It did not flow over the edge of the crater. Many feet down from the top it had torn a hole through the cone. I shall never forget the sight as long as I live. There was a vast arch in the black rock. From this arch rushed a clear torrent of lava. It flowed smoothly like honey. It glowed with all the splendor of the sun. It looked thin like golden water.

"'I could stir it with a stick,' said one of my friends.

"'I doubt it,' I said. 'See how slowly it flows. It must be very thick and heavy.'

"To test it we threw pebbles into it. They did not sink, but floated on like corks. We rolled in heavier stones of seventy or eighty pounds. They only made shallow dents in the stream and floated down with the current. A great rock of three hundred pounds lay near. I raised it upon end and let it fall into the lava. Very slowly it sank and disappeared.

"As the stream flowed on it spread out wider over the mountain. Farther down the slope it grew darker and harder. It started from the arch like melted gold. Then it changed to orange, to bright red, to dark red, to brown, as it cooled. At the lower end it was black and hard and broken like cinders.

"We climbed a little higher above the arch. There was a kind of chimney in the rock. Smoke and stream were coming out of it. I went close. The fumes of sulphur choked me. I reached out and picked some lumps of pure sulphur from the edge of the rock. For one moment the smoke ceased. I held my breath and looked down the hole. I saw the glare of red-hot lava flowing beneath. The mountain was a pot, full of boiling rock."

Another man writes of a visit in 1868, a quieter year.

"At first we climbed gentle slopes through vineyards and fields and villages. Sometimes we came suddenly upon a black line in a green meadow. A few years before it had flowed down red-hot. Further up we reached large stretches of rock. Here wild vines and lupines were growing in patches where the lava had decayed into soil. Then came bare slopes with dark hollow and sharp ridges. We walked on old stiff lava-streams. Sometimes we had to plod through piles of coarse, porous cinders. Sometimes we climbed over tangled, lumpy beds of twisted, shiny rock. Sometimes we looked into dark arched tunnels. Red streams had once flowed out of them. A few times we passed near fresh cracks in the mountain. Here steam puffed out.

"At last we reached a broad, hot piece of ground. Here were smoking holes. The night before I had looked at them with a telescope from the foot of the mountain. I had seen red rivers flowing from them. Now they were empty. Last night's lava lay on the slope, cooled and black. I was standing on it. My feet grew hot. I had to keep moving. The air I breathed was warm and smelled like that of an iron foundry. I pushed my pole into a crack in the rock. The wood caught fire. I was standing on a thin crust. What was below? I broke out a piece of the hard lava. A red spot glared up at me. Under the crust red-hot lava was still flowing. I knew that it would be several years before it would be perfectly cool."

So for three centuries people have watched Vesuvius at work. But she is much older than that—thousands of years older—older than any city or country or people in the world. In all that time she has poured out millions of tons of matter—lava, huge glassy boulders, little pebbles of pumice stone, long shining hairs, fine dust or ashes. All these things are different forms of melted rock. Sometimes the steam blows the liquid into fine dust; sometimes it breaks it into little pieces and fills them with bubbles. At another time the steam is not so strong and only pushes the stuff out gently over the crater's edge. Many different minerals are found in these rocks—iron, copper, lead, mica, zinc, sulphur. Some pieces are beautiful in color—blue, green, red, yellow. Precious stones have sometimes been found—garnets, topaz, quartz, tourmaline, lapis lazuli. But most of the stone is dull black or brown or gray.

All this heavy matter drops close to the mountain. And on calm days the ashes, also, fall near at home. Indeed, the volcano has built up its own mountain. But a heavy wind often carries the fine dust for hundreds of miles. Once it was blown as far as Constantinople and it darkened the sun and frightened people there. Some of the ashes fall into the sea. For years the currents carry them about from shore to shore. At last they settle to the bottom and make clay or sand or mud. The material lies there for thousands of years and is hard packed into a soft fine grained rock, called tufa. The city of Naples to-day is built of such stone that once lay under the sea. An earthquake long ago lifted the ocean bottom and turned it into dry land. Now men live upon it and cut streets in it and grow crops on it.

So for many miles about, Vesuvius has been making earth. Her ashes lie hundreds of feet deep. Men dig wells and still find only material that has been thrown out of the volcano. When this matter grows old and lies under the sun and rain it turns to good soil. The acids of water and air and plants eat into it. Rain wears it away. Plant roots crack the rocks open. The top layer becomes powdered and rotted and mixed with vegetable loam and is fertile soil. So the country all around the volcano is a rich garden. Tomatoes, melons, grapes, olives, figs, cover the land.

But Vesuvius alone has not made all this ground. She is in a nest of volcanoes. They have all been at work like her, spouting ashes and pumice and rocks and lava. Ten miles away is a wide stretch of country where there are more than a dozen old craters. Twenty miles out in the blue bay a volcano stands up out of the water. A hundred miles south is a group of small volcanic islands. They have hot springs. One has a volcano that spouts every five or six minutes. At night it is like a lighthouse for sailors. One of these Islands is only two thousand years old. The men of Pompeii saw it pushed up out of the sea during an earthquake. A little farther south is Mt. Aetna in Sicily. It is a greater mountain than Vesuvius and has done more work than she has done. So all the southern part of Italy seems to be the home of volcanoes and earthquakes.

There are many other such places scattered over the world—Iceland, Mexico, South America, Japan, the Sandwich Islands. Here the same terrible play is going on—thunder, clouds, falling ashes, scalding rain, flowing lava. The earth is being turned inside out, and men are learning what she is made of.

POMPEII TO-DAY

Years came and went and changed the world. The old gods died, and the new religion of Christ grew strong. The old temples fell into ruins, and new churches were built in their places. Instead of the old Roman in his white toga came merchants in crimson velvet and knights in steel armor and gentlemen in ruffles and modern men in plain clothes.

Among all these changes, Pompeii was almost forgotten. But after a long while people began to be much interested in ancient Italy. They read old Roman books, and learned of her wonderful cities. They began to dig here and there and find beautiful statues and vases and jewels. They read the story of Pompeii in an old Roman book—a whole city suddenly buried just as her people had left her!

"There we should find treasures!" they said. "We should see houses, temples, shops, streets, as they were seventeen hundred years ago. We should find them full of statues and rich things. Perhaps we should find some of the people who lived in ancient days. But where to dig?"

Their question was answered by accident. At that time certain men were making a tunnel to carry spring water from the hills across the country to a little town near Naples. The tunnel happened to pass over buried Pompeii. They dug up some blocks of stone with Latin inscriptions carved on them. After that other people found little ancient relics near the same place.

"This must be where Pompeii lies buried," the wise men said.

They began to excavate. That was about two hundred years ago. Ever since that time the work has gone on. Sometimes people have been discouraged and have given up. At other times six hundred men have been working busily. Kings have given money. Emperors and princes and queens have visited the excavations. Artists have made pictures of the ruins, and scholars have written books about them. But it is a great task to uncover a whole city that is buried ten or twelve feet deep. The excavation is not yet finished. Perhaps when you are old men and women the work will be completed, and a whole Roman city will be open to your eyes.

But even as it is to-day, that ghost of a city is among the world's wonders. There is the thick stone wall that goes all about the town. On its wide top the soldiers used to stand to fight in ancient days. Now the stones are fallen; its towers are broken; its gates are open. Yet there the battered little giant stands at its task of protecting the town. Out of its eight gates stretch the paved streets.

Perhaps some day you will cross the ocean to visit this "dead city." It lies on a slope at the foot of Vesuvius. Behind stands the tall, graceful volcano with its floating feather of steam and smoke. In front lies a little plain, and beyond it a long ridge of steep mountains. Off at the side shines the dark blue sea with island peaks rising out of it. On hillsides and plain are green vineyards and dark forests dotted with white farmhouses.

In some places there are high mounds of dirt outside the city wall. They are made by the ashes that have been dug out by the excavators and piled here. If you climb one of them you will be able to look over the city. You will find it a little place—less than a mile long and half a mile wide inside its ragged wall. And yet many thousand people used to live here. So the houses had to be crowded together. You will see no grassy lawns nor vacant lots nor playgrounds nor parks with pleasant trees. Many narrow streets cross one another and cut the city into solid blocks of buildings. You will be confused because you will see thousands of broken walls standing up, but no roofs. They are gone—crushed by the piling ashes long ago.

At last you will come down and go in at one of the gates through the rough, thick wall, past the empty watch towers. You will tread the very paving stones that men's feet trampled nineteen hundred years ago as they fled from the volcano. You will climb a steep, narrow street. This is the street the fishermen and sailors used in olden times when they came in from the river or sea, carrying baskets of fish or leading mules loaded with goods from their ships. This is the street where people poured out to the sea on that terrible day of the eruption.

You will pass a ruined temple of Apollo with standing columns and lonely altar and steps that lead to a room that is gone. A little farther on you will come out into a large open paved space. It is the forum. This used to be the busiest place in all Pompeii. At certain hours of the day it was filled with little tables and with merchants calling out and with gentlemen and slaves buying good's. But now it is empty and very still. Around the sides a few beautiful columns are yet standing with carved marble at the top connecting them. But others lie broken, and most of them are gone entirely. This is all that is left of the porches where men used to walk and talk of business and war and politics and gossip.

At one end of the forum is a high stone platform and wide stone steps leading up to a row of broken columns in front of a fallen wall. This is the ruin of the temple of Jupiter, the great Roman god. Daily, men used to come here to pray before a statue in a dim room. Here, in the ruins, the excavators found the head of that statue—a beautiful marble thing with long curling hair and beard, and calm face. They found, too, a great broken body of marble. And in that large body a smaller statue was partly carved. This was a puzzling thing, but the excavators studied it out at last. They said:

"Old Roman books tell us that sixteen years before the great eruption there had been another earthquake. It had shaken down many buildings and had cracked many walls. But the people loved their city, and when the earthquake was over, they began to rebuild and to make their houses and temples better than ever. We have found many signs of that earthquake. We have found uncarved blocks of marble in the forum. Evidently masons were at work there when the eruption stopped them. We have found rebuilt walls in some of the houses. And here is the temple of Jupiter being used as a marble shop. Probably the early earthquake had shaken down and broken the statue of the god. A sculptor was set to work to carve a new one from the ruin. But suddenly the volcano burst forth, the artist dropped his chisel and mallet, and here we have found his unfinished work—a statue within a statue."

Behind the roofless porches of the forum are other ruined buildings—where the officers of the city did business, where the citizens met to vote, where tailors spread out their cloth and sold robes and cloaks. One large market building is particularly interesting. You will enter a courtyard with walls all around it and signs of lost porches. Broken partitions show where little stalls used to open upon the court. Other stalls opened upon the street. In some of these the excavators found, buried in the ashes and charred by the fire, figs, chestnuts, plums, grapes, glass dishes of fruit, loaves of bread, and little cakes. Were customers buying the night's dessert when Vesuvius frightened them away? In a cool corner of the building is a fish market with sloping marble counter. Near it in the middle of the courtyard are the bases of columns arranged in a circle around a deep basin in the floor. In the bottom of this basin the excavators found a thick layer of fish scales. Evidently the masters used to buy their fish from the market in the corner. Then the slaves carried them here to the shaded pool of water and cleaned them and scaled them and washed them. In another corner the excavators found skeletons of sheep. Here was a pen for live animals which a man might buy for his banquet or for a sacrifice to his gods. His slave would lead the sheep away through the crowds. But on that terrible day when the volcano belched, the poor bleating animals were deserted. Their pen held them and the ashes covered them and to-day we can see their skeletons.
