As I have said before, Father Marquette was suffering much with fever. As for his companions, they wished to return, for, said one: “If we go farther south, some Spaniards will capture us, or we will be killed by fiercer Indians than we have yet met with.” So they started to ascend the muddy river, toiling terribly against the current, but ever watchful of a night attack, and careful to sleep in the canoes, well away from the bank. Yet on, on, they went towards the north until the mouth of the river Illinois was reached. Into this they turned, paddled to its source, portaged into gray Lake Michigan, and soon were homeward bound for the busy post of Sault Ste. Marie. Marquette was quite ill with the fever and worn out with the exertion of the long journey, so at Green Bay he remained at the Jesuit mission of St. Francis Xavier, established there some years before. Joliet, on the other hand—apparently an iron man—was feeling splendidly. He had traveled only 2,767 miles in a birch canoe and was as well and hearty as when he had started. A true athlete, this Joliet, and one who must have had muscles of steel! It was now September, and the explorers had been away for five months. It was also the time of stress and of storm on the Great Lakes, so it was thought best to pass the winter quietly at the little mission, there to write up the report of this wonderful journey. Both adventurers, therefore, sat down to rest, busying themselves in editing their journals. Marquette’s alone has been preserved; as for Joliet’s, his was upset in his canoe, when returning to Quebec in the following Spring, and all of his papers were lost in the frothing current of the raging La Chine rapids of the Ottawa River, near Montreal. Marquette’s account, with maps drawn from memory, reached his superiors in the Jesuit mission at Quebec, and they are to-day of great interest to historians, geographers, and antiquarians. On the way to Green Bay, the good priest had promised the Illinois Indians that he would return to them in the Spring, in order to preach the gospel. Although much shattered in health, because of the fever which had fastened itself upon him, he again started south in October, 1674. Dismissing his great accomplishment from his mind, again he turned to teach the savages the words of Christ. Reaching the Chicago River, he found it covered with ice, so he remained at a poor log cabin, near the shore of Lake Michigan. He was ill, but brave, and, when the warm breath of Spring again brought tassels to the willows, this noble priest of God pushed southward to the country of the friendly Illinois.
