LEWISTON — In the conventional sense, the University of Maine is the state’s only land-grant university: it received Indigenous land from the federal government over 150 years ago as an early endowment. By another definition, Colby and Bowdoin, to which the state gave a combined 234,000 acres, were the first land-grant colleges in Maine. Now, add to that list Bates College. The Legislature granted the Lewiston college 57,000 acres in northwestern Maine in the 1860s.
