It appears that the fountain of water was enchanted, and that the dragon had been set to guard it, so that no mortal might ever quench his thirst there. As the neighboring inhabitants carefully avoided the spot, it was now a long time (not less than a hundred years, or thereabouts) since the monster had broken his fast; and, as was natural enough, his appetite had grown to be enormous, and was not half satisfied by the poor people whom he had just eaten up. When he caught sight of Cadmus, therefore, he set up another abominable hiss, and flung back his immense jaws, until his mouth looked like a great red cavern, at the farther end of which were seen the legs of his last victim, whom he had hardly had time to swallow. But Cadmus was so enraged at the destruction of his friends, that he cared neither for the size of the dragon's jaws nor for his hundreds of sharp teeth. Drawing his sword, he rushed at the monster, and flung himself right into his cavernous mouth. This bold method of attacking him took the dragon by surprise; for, in fact, Cadmus had leaped so far down into his throat, that the rows of terrible teeth could not close upon him, nor do him the least harm in the world. Thus, though the struggle was a tremendous one, and though the dragon shattered the tuft of trees into small splinters by the lashing of his tail, yet, as Cadmus was all the while slashing and stabbing at his very vitals, it was not long before the scaly wretch bethought himself of slipping away. He had not gone his length, however, when the brave Cadmus gave him a sword thrust that finished the battle; and, creeping out of the gateway of the creature's jaws, there he beheld him still wriggling his vast bulk, although there was no longer life enough in him to harm a little child. But do not you suppose that it made Cadmus sorrowful to think of the melancholy fate which had befallen those poor, friendly people, who had followed the cow along with him? It seemed as if he were doomed to lose every body whom he loved, or to see them perish in one way or another. And here he was, after all his toils and troubles, in a solitary place, with not a single human being to help him build a hut. "What shall I do?" cried he aloud. "It were better for me to have been devoured by the dragon, as my poor companions were." "Cadmus," said a voice--but whether it came from above or below him, or whether it spoke within his own breast, the young man could not tell--"Cadmus, pluck out the dragon's teeth, and plant them in the earth."
