This is what it says, exactly as the scans read.

This township was not reduced to its present limits with its present name until March 13, 1822. It was named in honor of the Black family who came fi-om North Carolina in 1806 and settled a short distance northwest of Mount Vernon.

William Henry Harrison entered a portion of the land on which the city of Mount Vernon now stands. His claim called for 317 acres of Section 8. This claim he tried to sell to James Black, but he refused to buy because one of the McFaddin's had squatted on the land and refused to yield possession. Harrison afterward sold the land to Aaron "Williams, of Big Prairie, 111., for a horse and some money borrowed of James Black.

Machine-read from a century-old scan, so expect the errors a machine makes: misspelled names, dropped words, stray characters.
