In the spring of 1795 the directors of the Connecticut Land Company sent out surveyors through the Mohawk, over the portage of Wood creek, Oneida lake, and the Oswego river to Lake Ontario. At Buffalo the agent bought of the Indians their remaining claim to the lands east of the Cuyahoga river for five hundred pounds, New York currency, two beef cattle, and one hundred gallons of whiskey. The murder in 1774 without provocation of the family of Logan, a friendly chief of the Cayuga nation and of great influence, Jefferson shows was due to the drunkenness of two traders, Greathouse and Tomlinson, and caused Logan to deliver the speech which is often given in school readers. The Seminole War had the combined causes of slavery and liquor. President Jackson gave slave traders permission to buy slaves of the Seminole Indians. The trader, knowing that the Indians were intoxicated, would induce them to give bills of sale for negroes they did not own, and the complications thus caused led to the Seminole War. The Black Hawk War was directly caused by the liquor traffic, while the career of Pontiac, the ablest Indian statesman his race ever produced, illustrates that drunkenness was the bane of the Indian race. In the same speech in which Pontiac said, "our people love liquor and if we dwelt near your old village of Detroit, our warriors would be always drunk," he concluded his harangue with the desire that the rum barrel might be opened and his warriors allowed to quench their thirst. His life was ended by an English trader named Williamson, who bribed a strolling Indian of the Kaskia tribe by a barrel of rum to murder him, and for that reward the savage stole softly behind Pontiac while he was meditating in the forest and buried his hatchet in his brain.
