The boundary between Michigan and Wisconsin was first determined in the act that in 1836 created Wisconsin Territory. In ignorance of the real geography of the region this act described a supposititious line, under the belief that the Montreal River had its source in Lake Vieux Desert. Two years later Congress appropriated $3,000 for the survey of the Michigan-Wisconsin boundary. The appropriation was considered insufficient and no attempt was made to run the line until 1841. Then, the matter having been transferred to the War Department, an army engineer, Lieutenant Thomas J. Cram, was detailed to undertake the survey. Cram spent the summer of 1841 in Wisconsin’s northern forests, ascertained many facts about the lakes and streams therein, and reported them to the department. Two years later Cram was again detailed to search for the true Wisconsin-Michigan boundary. He spent four months under conditions involving much hardship, in the attempt to determine the line as nearly as possible in accordance with official description. In the report which he made to the head of his department he recommended the abandonment of Lake Vieux Desert as a determinating factor in the interstate boundary line.[123] The determination of the line rested until 1846, when, in the enabling act providing for the admission of Wisconsin, Congress established the line “to the mouth of the Menominee river; thence up the channel of the said river to the Brulé river; thence up said last mentioned river to Lake Brulé; thence along the southern shore of Lake Brulé in a direct line to the center of the channel between Middle and South Islands, in the Lake of the Desert [Vieux Desert]; thence in a direct line to the head waters of the Montreal river, as marked upon the survey made by Captain Cramm; thence down the main channel of the Montreal river to the middle of Lake Superior.” The constitution of Michigan, adopted in 1850, repeated the boundary article of Wisconsin’s enabling act with only slight verbal changes, including the omission of Captain Cram’s name. The fundamental laws of the two states were thus in accord concerning the line separating these states.
