“Without those brave men who did not hesitate, at the risk of being burnt alive, to go and open a new passage for the stream of fire, Catania would certainly have been lost,” remarked Jules.

“Catania would have been all burnt down, there is no doubt. To-day its calcined ruins would be buried under a bed of cold lava, and there would be nothing left but the name of the large town that had disappeared. Three or four stout-hearted men revive the courage of the terrified population; they hope that heaven will aid them in their devotion, and, ready to sacrifice their lives, they prevent the frightful disaster. Ah! may God give you grace, my dear child, to imitate them in the time of danger; for, you see, if man is great through his intelligence, he is still greater through his heart. In my old age, when I hear you spoken of, I shall be more gladdened by the good you may have done than by the knowledge you may have acquired. Knowledge, my little friend, is only a better means of aiding others. Remember that well, and when you are a man bear yourself in danger as did those of Catania. I ask it of you in return for my love and my stories.”

Jules furtively wiped away a tear. His uncle perceived that he had sown his word in good ground.


CHAPTER XLVII
THE STORY OF PLINY

“TO teach you what the cinders thrown up by a volcano can do, I am now going to tell you a very old story, just as it was transmitted to us by a celebrated writer of those old times. This writer is called Pliny. His writing is in Latin, the great language of those days.

“It was in the year 79 of our era. Contemporaries of our Savior were still living. Vesuvius was then a peaceful mountain. It was not terminated then, as to-day, by a smoking cone, but by a table-land slightly concave, the remains of an old filled-up crater where thin grasses and wild vines grew. Very fertile crops covered its sides; two populous towns, Herculaneum and Pompeii, lay stretched at its base.

“The old volcano, which seemed forever lulled, and whose last eruptions went back to times beyond the memory of man, suddenly awakened and began to smoke. On the 23d of August, about one o’clock in the afternoon, an extraordinary cloud, sometimes white, sometimes black, was seen hovering over Vesuvius. Impelled violently by some subterranean force, it first rose straight up in the form of a tree-trunk; then, after attaining a great height, it sank down under its own weight and spread out over a wide area.

“Now, there was at that time at Messina, a seaport not far from Vesuvius, an uncle of the author who has handed down these things to us. He was called Pliny, like his nephew. He commanded the Roman fleet stationed at this port. He was a man of great courage, never retreating from any danger if he could gain new knowledge or render aid to others. Surprised at the singular cloud that hovered over Vesuvius, Pliny immediately set out with his fleet to go to the aid of the menaced coast towns and to observe the terrible cloud from a nearer point. The people at the foot of Vesuvius were fleeing in haste, wild with fear. He went to the side where all were in flight and where the peril appeared the greatest.”

“Fine!” cried Jules. “Courage comes to you when you are with those who are not afraid. I love Pliny for hastening to the volcano to learn about the danger. I should like to have been there.”
