Immediately north of Plainfield, lies the town of Wheatland-Township 37, Range 9–the northwestern corner of the county. With slight exceptions, this township remained unsettled until after 1840. Two things contributed to delay its settlement. Lying mostly outside of the Indian boundary line, it was not surveyed until 1837 or 1838, and not brought into market until 1841; and being entirely prairie (with a trifling exception in the northeast corner), it did not so early attract settlers as other portions. But this was also an advantage, as it was from these circumstances, kept out of the hands of speculators, and reserved.
