It is doubtless true that "truth, crushed to earth, will rise again," but the converse proposition of the poet that error dies amid its worshipers requires qualification. Certainly in the matter under discussion La Salle as early as 1683 dealt the errors of Joliet with respect to the Chicago Portage a crushing blow. Yet these self-same errors were destined to "rise again," and in the early nineteenth century it was again commonly reported that a practicable waterway from Lake Michigan to the Mississippi could be attained by the construction of a canal a few miles in length across what for convenience may be termed the short Chicago Portage, from the south branch of the Chicago River through Mud Lake to the Des Plaines. Even capable engineers threw the weight of their opinion in support of this fallacy.[14] But the young state of Illinois learned to her cost, in the hard school of experience, the truth of La Salle's observations. The canal of half a league extended in the making to a hundred miles and required for its construction years of time and the expenditure of millions of dollars.

We may now consider the dispute between Joliet and La Salle over the character of the Chicago Portage in the light of the information afforded by the statements of later writers. It will follow from what has already been said that the secondary statements, whether of travelers or of gazetteers and other compendiums of information, made in the early part of the nineteenth century, must be subjected to critical examination. The only way in which this may be done is by a resort to the sources; and our conclusions concerning the Chicago-Illinois Portage and route must be based upon the testimony of those who actually used it, or were familiar with the use made of it by others. A study of these sources makes it clear that the Des Plaines River was subject to great fluctuation at different seasons, or even as between periods of drought and periods of copious rainfall, and that the length and character of the portage at any given time depended entirely upon the stage of water in the Des Plaines. During the brief period of the spring flood boats capable of carrying several tons might pass between Lake Michigan and the Des Plaines and along the latter stream without meeting with obstacles other than those incident to the high stage of the water. The extreme range of the fluctuation was many feet.[15] Its effect upon the character of the Des Plaines was to cause it to pass through all the gradations from a raging torrent to a stream with no discharge, dry except for the pools which marked its course. There were times, then, in connection with these fluctuations, when the stream might be navigable for canoes, although it would not permit the passage of boats of greater draft.
[15] Schoolcraft estimated its depth in the seasons of periodical floods at eight to ten feet (Summary Narrative of an Exploratory Expedition to the Sources of the Mississippi River, in 1820, 398). See also Marquette's description of the spring flood of 1675, in Jesuit Relations, LIX, 181.
The duration of the spring flood was put by La Salle at fifteen or twenty days. At this time the flood was heavier than that of the Rhone, and a portion of it found its way through Mud Lake and the south branch of the Chicago River into Lake Michigan. The effect of this on the portage, obvious in itself, is described in many of the sources. Marquette, who was flooded out of his winter camp on the South Branch in the latter part of March, 1675, found no difficulty, aside from the obstacles presented by the floating ice, in passing from that point down the Des Plaines.[16] He reports the water as being twelve feet higher than when he passed through here in the late summer of 1673. In 1821, in a time of high water, Ebenezer Childs passed up the Illinois and Des Plaines rivers to Chicago in a small canoe.[17] No month or date is given for this trip, but Childs expressly states that there had been heavy rains for several days before his arrival at the Des Plaines. He was unable to find any signs of a portage between the Des Plaines and the Chicago. When he had ascended the former to a point where he supposed the portage should begin he left it and taking a northeasterly course perceived, after traveling a few miles, the current of the Chicago. The whole intervening country was inundated, and not less than two feet of water existed all the way across the portage. Two years later Keating, the historian of Major Long's expedition to the source of the St. Peter's River, which passed through Chicago in early June, 1823, was informed by Lieutenant Hopson, an officer at Fort Dearborn, that he had crossed the portage with ease in a boat loaded with lead and flour.[18] Of similar purport to the testimony of Childs and Hopson is the account given by Gurdon S. Hubbard of his first ascent of the Des Plaines with the Illinois "brigade" of the American Fur Company in the spring of 1819.[19] The passage from Starved Rock up the river to Cache Island against the heavy current was difficult and exhausting. From this point, with a strong wind blowing from the southwest, sails were hoisted and the loaded boats passed rapidly up the Des Plaines and across the portage to the Chicago, "regardless of the course of the channel."
