In spite of all these difficulties, the little craft was finished, and, at the opening of the ice in the spring, there glided down into the Niagara the first keel that ever cut the water of the Upper Lakes, the forerunner of to-day's enormous tonnage. Her figure-head was a mythical monster, and her name the "Griffin," both taken from Frontenac's coat of arms.

On August 7, the "Griffin" fired her cannon, spread her sails, and bore away up Lake Erie, carrying the expedition which La Salle hoped would make him master of the Mississippi Valley. The plan was to sail to the head of Lake Michigan, near the site of Chicago, then to march to the Illinois River; there to build another vessel, and in the latter to sail down the Mississippi, into the Gulf, and to the very West Indies—an enterprise of Titanic audacity.

The first part of the voyage was delightful. We may wonder whether our voyagers saw one amazing sight which Jonathan Carver describes. "There are," he says, "several islands near the west end of it [Lake Erie] so infested with rattlesnakes that it is very dangerous to land on them. The lake is covered, near the banks of the islands, with the large pond-lily, the leaves of which lie on the water so thick as to cover it entirely for many acres together; and on each of these lay, when I passed over it, wreaths of water-snakes basking in the sun, which amounted to myriads!"

On the shore were verdant prairies and fine forests. When the voyagers entered Detroit River they saw herds of deer and flocks of wild turkeys, and the hunters easily kept the party supplied with venison and bear meat. On they sailed, across Lake St. Clair and out upon Lake Huron, passed within sight of the Manitoulins, and finally came to anchor in the cove of Mackinaw Strait, where were the famous trading-post and mission-station of Michillimackinac.

At Green Bay La Salle found some of his men who had remained faithful and had collected a large store of furs. This circumstance caused him new perplexity. He had furs enough to satisfy his creditors, and he was strongly moved to go back to the colony and settle with them. On the other hand, he dreaded leaving his party, which would surely be tampered with by his enemies. Should his strong hand be withdrawn, the party probably would go to pieces. Finally he decided to remain with the expedition and to send the "Griffin" back with her valuable cargo to Fort Niagara and with orders to return immediately to the head of Lake Michigan. It was an unfortunate decision. The vessel's pilot was already under suspicion of having treacherously wrecked the vessel which perished on Lake Ontario. The "Griffin" sailed and never was heard of again. Whether she foundered on the lake, was dashed on the shore, or was plundered and scuttled, La Salle never knew. He believed the latter to have been the case. Her loss was the breaking of an indispensable link in the chain. But La Salle was still ignorant of it, and he went on his way hopefully to the head of Lake Michigan.

A hard time the men had in paddling the heavily laden canoes, subsisting on a scant ration of Indian corn, and at night dragging the canoes up a steep bank and making their cheerless camp. By the time that they reached the site of Milwaukee all were worn out.

They were glad enough when they saw two or three eagles among a great gathering of crows or turkey-buzzards, and, hastening to the spot, they found the torn carcass of a deer, lately killed by wolves. However, as they neared the head of the lake, game became more abundant, and La Salle's famous Mohegan hunters had no difficulty in providing bear's meat and venison.

Winter was fast setting in, and La Salle was anxious to go on to the Illinois towns before the warriors should go away on their usual winter hunting. But he was compelled to wait for Tonty, an Italian officer of great courage and splendid loyalty who had come out to America as his lieutenant. With twenty men, he was making his way by land down the eastern shore. At last he appeared, with his men half-starved, having been reduced to living on acorns. But where was the "Griffin"? This was the place appointed for her meeting with the expedition. But there were no tidings of her fate. After waiting as long as he could, La Salle, with heavy forebodings, pushed on.

Now the explorers shouldered their canoes and struck out across the frozen swamps. At last they came to a sluggish streamlet, the headwaters of the Kankakee. They launched their canoes on it and were carried, within a few days, into a prairie country strewn with the carcasses of innumerable buffalo, for this was a favorite hunting-ground of the Indians. But not one of the animals was in sight. The men were nearly starving and, at the best, discontented and sullen. Two lean deer and a few geese, all the game that the hunters had been able to secure within several days, were short commons for thirty-three men with appetites sharpened by traveling in the keen December air. It was a God-send when they found a buffalo-bull mired fast. The famished men quickly despatched him, and by the efforts of twelve of their number dragged the huge carcass out of the slough.

Down the Illinois River the voyagers traveled until they came in sight of wigwams on both sides of the river. La Salle expected trouble, for his enemies had been busy among the Illinois, stirring them up against him by representing that he had incited the Iroquois to make war upon them. He ordered his men to take their arms. Then the eight canoes in line abreast drifted down between the two wings of the encampment.
