As elsewhere throughout the Northwest, the French missionaries were here the earliest explorers, Father Marquette coming in 1673, and afterwards Hennepin, Joliet and La Salle, whose names are so numerously reproduced in the Northwestern States. The French built at the mouth of the river Fort Chicagou, for a trading-post, and held it until the English conquered Canada. When the earlier American settlers ventured to this frontier, the Indians on Lake Michigan were the Pottawatomies, and were hostile. The Government in 1804 built Fort Dearborn, near the mouth of the Chicago River, to control them. These Indians joined in the crusade of the Prophet and Tecumseh, and when the war with England began in 1812, attacked and captured the fort, massacring the garrison. The post was subsequently re-established, and the Indians were ultimately removed west of the Mississippi. Not long afterwards it was said the first purchase of the site of Chicago took place, wherein a large part of the land now occupied was sold for a pair of boots. When the town plot was originally surveyed, twelve families were there in addition to the garrison of Fort Dearborn, and in 1831 it had one hundred people. In 1833 the town government was organized, and it had five hundred and fifty inhabitants and one hundred and seventy-five buildings. Five trustees then ruled Chicago, and collected $49 for the first year's taxes. Collis P. Huntington, the Pacific Railway manager, says that in 1835, being possessed of a good constitution and a pair of mules, but little else, he was out that way prospecting, and found at Chicago nothing but a swamp and a few destitute farmers, all anxious to move. One of these farmers came to him with the deed of his farm of two thousand acres, and offered to trade it for his pair of mules. Huntington adds: "I was not very favorably impressed with the settlement and declined his offer, and finally continued my travel west, and that farm is to-day the business centre of Chicago."
