Far otherwise was it with the French. Priests and traders were both full of a desire for conquest and adventure. Many of them indeed were so driven by the roving spirit that they left the towns altogether and lived alone among the forests, tracking the wild animals, and only coming to towns to sell the skins and get provisions. These trappers brought back with them many strange tales of the forests and unknown wilds. They spoke of the Mississippi or "great water" of which the Indians told marvelous tales. And at length it seemed to their hearers that this great water could be no other than the long sought passage to India and the East. Many people, fired by these tales, went in search of this great water. In 1673 two priests named Marquette and Joliet were the first to discover it. For many miles they floated down the Mississippi. On either side stretched endless forests and plains of waving grass, haunts of wild animals and of the Indians, - almost as wild. On they went, past the mouth of the yellow Missouri, on still till they came to the river Arkansas. At last, sure that the great river went southward and not westward as they had supposed, they decided to return. It had been easy enough floating down, but now they had to battle against the stream, and it was only after weeks of toil that they at length reached Canada again with their news. When he heard their story another adventurer named René Robert Cavelier Sieur de la Salle became eager to make certain of their discovery, and follow the river all the way to its mouth. With great care and trouble he made his arrangements. He thought it would be impossible to compass so great a journey by canoes, so he built a little ship which he called the Griffin. It was the first ship which had been seen by the Indians round Lake Erie, and in amazement and fear they came to stare at it. In their ignorant terror they would have destroyed it had not careful watch been kept. From the very beginning of his expedition La Salle found many difficulties. But at length they all seemed to be overcome, and he set out with his friend, Henri de Tonty, and about forty men. Tonty was a man of courage, as bold and enterprising as La Salle himself. He was, too, much feared by the Indians, who thought him a great Medicine Man. For while fighting in Europe he had had one hand shot off. But he had replaced it with an iron hand, which he always wore covered with a glove. The Indians did not know this, and once or twice when they had been troublesome he had brought them to order by knocking them down with this hand. Not knowing the secret of it they marvelled greatly at his strength, and, fearing him accordingly, called him Iron Hand.
