Knuck Harris and other moved from Mount Vernon to Michigan .

The Detroit Daily Aevertiser [ sp] states that a project is on foot to establish a colony or community of the colored people on the state or government lands north of the Grand River in Michigan . An agent from Xenia , Ohio , has been out to look at the country and make a report to his brethren in that state. The purpose is, to buy a large tract, equal to one of the organized counties and settle it exclusively with the colored race. They think in this way the Legislature will be forced to give them political and municipal rights and privileges. The colored people have a large and flourishing colony, in Mercer county, (we believe) Ohio , which has been in successful operation some years. The Times, January 27, 1846
