Once more Eurystheus had given Hercules up for lost: and the snow prevented him from hearing any news beforehand. So when, while he was standing at the city gate, there suddenly appeared before him, not only Hercules--all grim and rough from his year's hunting--but the largest and most savage wild boar in the world, looking ready to devour him, he was so terrified that he whisked like a frightened mouse into his pot, and did not dare come out again for seven days. As for Chiron the Centaur, he became a constellation in heaven, where he is still to be seen. He was the teacher of nearly all the heroes and demi-gods: and after his death there seems to have been an end of them. There have been plenty of brave men since; but not like Castor and Pollux, Perseus, Theseus, and Hercules. Nor, since that fatal day, does one hear of the Centaurs any more. Thus did one passing fit of causeless anger, instantly repented of, destroy these wisest and most valiant creatures, and deprive the whole world of more than it has ever regained during thousands of years. Hercules solemnly sacrificed the boar, and then took a little rest, meditating on all that had befallen. But his rest was not to be for long. For there was Eurystheus in his pot, trying to think of something that should keep him occupied forever. And--"I have it!" he exclaimed at last, summoning Hercules by a stroke on his pot's brazen side. PART VI.--HIS FIFTH LABOR: THE AUGEAN STABLE. The next labor which Eurystheus laid upon Hercules was to clean out a stable. That does not sound very much after the others. But then the stable was that of Augeas, King of Elis, which was at once the largest and the dirtiest in the whole world. Augeas had a prodigious number of oxen and goats, and the stable in which they were all kept had never been cleaned. The result was a mountain of filth and litter, which not even Hercules could clear away in a lifetime--not, of course, from want of strength, but from want of time. Hercules beheld with disgust and dismay the loathsome and degrading toil in which he was to spend the rest of his days. The other labors had at least been honorable, and befitting a prince: this would have appalled a scavenger. "It is very good of such a hero as you," said Augeas, "to undertake to clean my stable. It really does want cleaning, as you see: and it was very kind of Eurystheus to think of it. You shall not find me ungrateful. I will give you one ox and one goat in every ten--when the job is done." He could very safely promise this, because he knew that the job could never be done. "I am not serving for hire," said Hercules. "Nevertheless it is only right that you should not let your stable get into such a state as this, and then get it put right for nothing. You want a lesson: and you shall have it, too."
