The passage below about the formation of Brown County in 1840 further elaborates on the La Fontaine railroad story as explained in this blog back in April:
As you might recall, Governor Doty's plan was to bypass the Fox River's rapids by a railroad from the village of La Fontaine near present-day Kaukauna to an envisioned "Winnebago CIty" on the northern shore of Lake Winnebago between present-day Menasha and the town of Cliffton (High Cliff).
But in this case, several years later, a canal was now the prescribed means to avoid the Fox River problem. Of course, as we now know, this was eventually solved by a series of locks.
