Note from page 38: 12. The Land Law of 1800 allowed the purchase of federal land on four years' credit at $2.00 per acre, and in 1804 the minimum allowable purchase was established at 160 acres. It appears that under the Act of March 2, 1821, Thomas Lincoln relinquished half of this original purchase, retaining 80 acres for which he was able to pay in full. See William E. Bartelt, "The Land Dealings of Spencer County, Indiana, Pioneer Thomas Lincoln," Indiana Magazine of History 87 (1991): 211 — 23.
