"The northward current of the eastern shore of Lake Michigan and the southward current of the western shore," says a writer exact in knowledge, "naturally made the St. Joseph portage a return route to Canada, and the Chicago portage an outbound one." But though La Salle was a careful observer and must have known that what was then called the Chekago River afforded a very short carrying to the Desplaines or upper Illinois, he saw fit to use the St. Joseph both coming and going.
His march to Fort Frontenac he afterwards described in a letter to one of the creditors interested in his discoveries.
"Though the thaws of approaching spring greatly increased the difficulty of the way, interrupted as it was everywhere by marshes and rivers, to say nothing of the length of the journey, which is about five hundred leagues in a direct line, and the danger of meeting Indians of four or five different nations, through whose country we were to pass, as well as an Iroquois army which we knew was coming that way; though we must suffer all the time from hunger; sleep on the open ground, and often without food; watch by night and march by day, loaded with baggage, such as blanket, clothing, kettle, hatchet, gun, powder, lead, and skins to make moccasins; sometimes pushing through thickets, sometimes climbing rocks covered with ice and snow; sometimes wading whole days through marshes where the water was waist deep or even more,--all this did not prevent me from going to Fort Frontenac to bring back the things we needed and to learn myself what had become of my vessel."
Carrying their canoes where the river was frozen, and finally leaving them hidden near where the town of Joliet now stands, La Salle and his men pushed on until they reached the fort built at the mouth of the St. Joseph. Here he found the two voyageurs he had sent to search for the Griffin. They said they had been around the lake and could learn nothing of her. He then directed them to Tonty, while he marched up the eastern shore. This Michigan region was debatable ground among the Indians, where they met to fight; and he left significant marks on the trees, to make prowlers think he had a large war party. A dozen or twenty roving savages, ready to pounce like ferocious wildcats on a camp, always peeled white places on the trees, and cut pictures there of their totem, or tribe mark, and the scalps and prisoners they had taken. They respected a company more numerous than themselves, and avoided it.
