When Indiana came to be erected, it was seen that to adopt the east-and-west line, established by the ordinance, would be to deprive her entirely of any part of the coast of Lake Michigan. In order, therefore, to satisfy her, Congress took another strip, ten miles wide, from the southern border of Michigan, and gave it to the new State. Michigan made no objection to this fresh violation of the agreement of 1787, because there were no important harbors or towns involved.

Illinois next knocked at the door of the Union. The same conditions applied to her as to Indiana; a strict construction of the ordinance would deprive her of an opening on the lake. The Illinois delegate who argued this matter in Congress was shrewd; he contended that his State must become intimately connected with the growing commerce of the northern lakes, else she would be led, from her commercial relations upon the south-flowing Mississippi and Ohio rivers, to join a Southern confederacy in case the Union should be broken up. This was in 1818, and shows how early in our history there had come to be, in the minds of some far-seeing men, a fear that the growing power of slavery might some time lead to secession. The argument prevailed in Congress, and there was voted to Illinois a strip of territory sixty-one miles wide, lying north of the east-and-west line.

Thus again was the region later to be called Wisconsin deprived of a large and valuable tract. When Wisconsin Territory was created, there was a great deal of indignation expressed by some of her people, at being deprived of this wide belt of country embracing 8500 square miles of exceedingly fertile soil, numerous river and lake ports, many miles of fine water power, and the sites of Chicago, Rockford, Freeport, Galena, Oregon, Dixon, and numerous other prosperous cities.

An attempt was made in 1836, at the time the Territory was established, to secure for Wisconsin's benefit the old east-and-west line, as its rightful southern boundary. But Congress declined to grant this request. Three years later, the Wisconsin Territorial legislature declared that "a large and valuable tract of country is now held by the State of Illinois, contrary to the manifest right and consent of the people of this Territory."

The inhabitants of the district in northern Illinois which was claimed by Wisconsin, were invited by these resolutions to express their opinion on the matter. Public meetings were consequently held in several of the Illinois towns interested; and resolutions were adopted, declaring in favor of the Wisconsin claim. The movement culminated in a convention at Rockford (July 6, 1839), attended by delegates from nine of the fourteen Illinois counties involved. This convention recommended the counties to elect delegates to a convention to be held in Madison, "for the purpose of adopting such lawful and constitutional measures as may seem to be necessary and proper for the early adjustment of the southern boundary."

Curiously enough, the weight of public sentiment in Wisconsin itself did not favor the movement. At a large meeting held in Green Bay, the following April, the people of that section passed resolutions "viewing the resolutions of the legislature with concern and regret," and asking that they be rescinded. With this, popular agitation ceased for the time; and in the following year the legislature promptly defeated a proposition for the renewal of the question.

Governor Doty, however, was a stanch advocate of the idea, and at the legislative session of 1842 contrived to work up considerable enthusiasm in its behalf. A bill was reported by the committee on Territorial affairs, asking the people in the disputed tract to hold an election on the question of uniting with Wisconsin. There were some rather fiery speeches upon the subject, some of the orators going so far as to threaten force in acquiring the wished-for strip; but the legislature itself took no action. However, in Stephenson and Boone counties, Illinois, elections were actually held, at which all but one or two votes were cast in favor of the Wisconsin claim.

Governor Doty, thus encouraged, busily continued his agitation. He issued proclamations warning Illinois that it was "exercising an accidental and temporary jurisdiction" over the disputed strip, and calling on the two legislatures to authorize the people to vote on the question of restoring Wisconsin to her "ancient limits." At first, neither the legislatures of Illinois nor Wisconsin paid much attention to the matter. Finally, in 1843, the Wisconsin legislature sent a rather warlike address to Congress, in which secession was clearly threatened, unless the "birthright of Wisconsin" were restored. Congress, however, very sensibly paid no heed to the address, and gradually the excitement subsided, until eventually Wisconsin was made a State, with her present boundaries.
