They turned into the Illinois when they reached that river, and journeyed up its winding course, delighted with its fertile basin, rich with fine forests, cattle, deer, goats, and beaver, and beautiful with clear streams and lovely lakes, on which floated great numbers of swans. When they reached the head of the river, an Indian chief guided them through the forests to Green Bay, which they reached in September, well satisfied with their journey, and convinced that the Mississippi led to the Gulf of Mexico.

Joliet no sooner told the story of his expedition than a gentleman of Normandy living in Canada resolved to undertake a journey to the mouth of the Mississippi, and to the Pacific. This man was Robert Cavalier de la Salle, and in August, 1679, he left Canada equipped for a voyage down the Mississippi; but, being detained by the loss of his vessel and an attack of the Iroquois upon the Illinois, who were the friends of the French, it was two years after that date, 1681, before he found himself actually on his way.

They left by the way of the Chicago River, which they travelled down in sledges, the river being frozen over, and even when they reached the Mississippi they were detained some days by the ice; but at last they were able to begin the descent, and, like the former expedition, passed many days before they came to an Indian village that was inhabited.

The first notice they had of their approach to a settlement came from the drums and war-cries of the people who had assembled on the bank. La Salle immediately landed on the other side of the river; and, setting his men to work, they soon had a fort built, and were prepared to defend themselves. The Indians, seeing this, changed their tactics, and sent some messengers across the river in a canoe. La Salle went down to the shore carrying the calumet, which was received by the savages with respect, and friendly feeling was at once established.

The Frenchmen were very glad of this, as during the three days they spent there they learned many things about the Indians farther down the river, and were also well supplied with food for their journey; for this village was situated in the midst of orchards and fields, and the people were very intelligent and courteous, having pleasant manners, and being liberal and hospitable. La Salle planted a cross bearing the arms of France, and parted from his new friends with many expressions of gratitude. The Indians sent with him some interpreters, who introduced him to a friendly tribe some distance farther down, and La Salle found these Indians also very intelligent and hospitable. He describes their houses as being built of mud and straw, with cane roofs, and furnished with bedsteads, tables, etc. They also had temples where their chiefs were buried, and wore white clothing spun from the bark of a tree. These were very different habits from those that La Salle had seen among the Indians in the north, and he concluded that he must be nearing the end of his journey.

This proved to be true, for two weeks after he found the river dividing into three branches; he took one branch and two of his men the others, and in a short time they found that the water was salt, and knew that they had reached the mouth of the river; a little farther on they saw the sea, and found that they had reached the Gulf of Mexico by the way of the Mississippi.

On April 9, 1682, a cross was raised, upon which were inscribed the arms of France; then, after a religious ceremony, La Salle took possession of the Mississippi and all its branches, together with all the lands bordering them, in the name of the king of France. A few days after he turned his face homeward; but, being detained by sickness, did not reach Quebec until the next year. However, he had sent the accounts of his voyage on before him, and these had been forwarded to France; and, after some delay, a new expedition left France, whither La Salle had gone; the object of this expedition was to found a colony at the mouth of the Mississippi.

All might have gone well, had it not been for the jealousy of Beaujeu, the captain of the fleet, who refused to follow La Salle's advice about landing. As they coasted along the Gulf, from their ignorance of the coast, they passed the mouth of the Mississippi, and went farther westward than they had meant to. La Salle wished to turn back and search for the mouth of the river, but Beaujeu refused to do this, and insisted upon entering Matagorda Bay in Texas. Here La Salle was obliged to have his stores landed; and, as soon as this was done, Beaujeu sailed back to France again, caring little what became of his fellow-voyagers.

But La Salle was not to be disheartened by such a mishap as this. He cheered the hearts of his men by his hopeful words, and they set about establishing the colony at once. They found the climate agreeable, and the natives friendly and willing to trade; they belonged to the same race as those on the Mississippi, and, like them, lived in large villages, and had comfortably furnished houses. La Salle had no fear in leaving his colony among these well-disposed natives; and, as soon as it was possible, he left his company and went in search of the Mississippi, which he had hopes of finding without difficulty.

But the river was farther off than he knew, and he was an utter stranger to the country; and, although he turned again and again, two years passed and he had not yet seen its shining waters. At last he determined to take half the colony and find his way to Canada, where he might obtain supplies, as they had received nothing from France since their arrival, owing to the bad report of La Salle that Beaujeu had taken back.
