its heads. But this looked like an endless task, for no sooner had he cut off one head than two grew in its place. At the same time an enormous crab came to the help of the hydra and began biting the hero's foot. Killing this with his club, he called to Iolaus for help.

The latter had lighted a torch, set fire to a portion of the nearby wood, and with brands therefrom touched the serpent's newly growing heads and prevented them from living. In this way the hero was at last master of the situation and was able to cut off even the head of the hydra that could not be killed. This he buried deep in the ground and rolled a heavy stone over the place. The body of the hydra he cut into half, dipping his arrows in the blood, which was poisonous.

From that time the wounds made by the arrows of Hercules were fatal.

The Third Labor

The third demand of Eurystheus was that Hercules bring to him alive the hind Cerynitis. This was a noble animal, with horns of gold and feet of iron. She lived on a hill in Arcadia, and was one of the five hinds which the goddess Diana had caught on her first hunt. This one, of all the five, was permitted to run loose again in the woods, for it was decreed by fate that Hercules should one day hunt her.

For a whole year Hercules pursued her; came at last to the river Ladon; and there captured the hind, not far from the city Oenon, on the mountains of Diana. But he knew of no way of becoming master of the animal without wounding her, so he lamed her with an arrow and then carried her over his shoulder through Arcadia.

Here he met Diana herself with Apollo, who scolded him for wishing to kill the animal that she had held sacred, and was about to take it from him.

"Impiety did not move me, great goddess," said Hercules in his own defense, "but only the direst necessity. How otherwise could I hold my own against Eurystheus?"

And thus he softened the anger of the goddess and brought the animal to Mycene.

The Fourth Labor

Then Hercules set out on his fourth undertaking. It consisted in bringing alive to Mycene a boar which, likewise sacred to Diana, was laying waste the country around the mountain of Erymanthus.

On his wanderings in search of this adventure he came to the dwelling of Pholus, the son of Silenus. Like all Centaurs, Pholus was half man and half horse. He received his guest with hospitality and set before him broiled meat, while he himself ate raw. But Hercules, not satisfied with this, wished also to have something good to drink.

"Dear guest," said Pholus, "there is a cask in my cellar; but it belongs to all the Centaurs jointly, and I hesitate to open it because I know how little they welcome guests."

"Open it with good courage," answered Hercules, "I promise to defend you against all displeasure."

As it happened, the cask of wine had been given to the Centaurs by Bacchus, the god of wine, with the command that they should not open it until, after four centuries, Hercules should appear in their midst.

Pholus went to the cellar and opened the wonderful cask. But scarcely had he done so when the Centaurs caught the perfume of the rare old wine, and, armed with stones and pine clubs, surrounded the cave of Pholus. The first who tried to force their way in Hercules drove back with brands he seized from the fire. The rest he pursued with bow and arrow, driving them back to Malea, where lived the good Centaur, Chiron, Hercules' old friend. To him his brother Centaurs had fled for protection.

But Hercules still continued shooting, and sent an arrow through the arm of an old Centaur, which unhappily went quite through and fell on Chiron's knee, piercing the flesh. Then for the first time Hercules recognized his friend of former days, ran to him in great distress, pulled out the arrow, and laid healing ointment on the wound, as the wise Chiron himself had taught him. But the wound, filled with the poison of the hydra, could not be healed; so the centaur was carried into his cave. There he wished to die in the arms of his friend. Vain wish! The poor Centaur had forgotten that he was immortal, and though wounded would not die.

Then Hercules with many tears bade farewell to his old teacher and promised to send to him, no matter at what price, the great deliverer, Death. And we know that he kept his word.

When Hercules from the pursuit of the other Centaurs returned to the dwelling of Pholus he found him also dead. He had drawn the deadly arrow from the lifeless body of one Centaur, and while he was wondering how so small a thing could do such great damage, the poisoned arrow slipped through his fingers and pierced his foot, killing him instantly. Hercules was very sad, and buried his body reverently beneath the mountain, which from that day was called Pholoë.

Then Hercules continued his hunt for the boar, drove him with cries out of the thick of the woods, pursued him into a deep snow field, bound the exhausted animal, and brought him, as he had been commanded, alive to Mycene.

The Fifth Labor

Thereupon King Eurystheus sent him upon the fifth labor, which was one little worthy of a hero. It was to clean the stables of Augeas in a single day.

Augeas was king in Elis and had great herds of cattle. These herds were kept, according to the custom, in a great inclosure before the palace. Three thousand cattle were housed there, and as the stables had not been cleaned for many years, so much manure had accumulated that it seemed an insult to ask Hercules to clean them in one day.

When the hero stepped before King Augeas and without telling him anything of the demands of Eurystheus, pledged himself to the task, the latter measured the noble form in the lion-skin and could hardly refrain from laughing when he thought of so worthy a warrior undertaking so menial a work. But he said to himself: "Necessity has driven many a brave man; perhaps this one wishes to enrich himself through me. That will help him little. I can promise him a large reward if he cleans out the stables, for he can in one day clear little enough." Then he spoke confidently:

"Listen, O stranger. If you clean all of my stables in one day, I will give over to you the tenth part of all my possessions in cattle."

Hercules accepted the offer, and the king expected to see him begin to shovel. But Hercules, after he had called the son of Augeas to witness the agreement, tore the foundations away from one side of the stables; directed to it by means of a canal the streams of Alpheus and Peneus that flowed near by; and let the waters carry away the filth through another opening. So he accomplished the menial work without stooping to anything unworthy of an immortal.

When Augeas learned that this work had been done in the service of Eurystheus, he refused the reward and said that he had not promised it; but he declared himself ready to have the question settled in court. When the judges were assembled, Phyleus, commanded by Hercules to appear, testified against his father, and explained how he had agreed to offer Hercules a reward. Augeas did not wait for the decision; he grew angry and commanded his son as well as the stranger to leave his kingdom instantly.

The Sixth Labor

Hercules now returned with new adventures to Eurystheus; but the latter would not give him credit for the task because Hercules had demanded a reward for his labor. He sent the hero forth upon a sixth adventure, commanding him to drive away the Stymphalides. These were monster birds of prey, as large as cranes, with iron feathers, beaks and claws. They lived on the banks of Lake
