The only grist-mill in the township [Upper Providence Township] in 1799, except that of Thomas Bishop, was owned by Jacob Siter, who was assessed in that year on twenty-seven acres of land, — a grist-mill, plaster-mill, and a frame smith-shop. Where this mill was located is not known, for in 1802 his name does not appear in the assessment-roll as owning a mill. That he lived on Crum Creek is evident from the fact that he was also assessed on forty-seven acres of land in Marple Township. On the 23d of March, 1801, Abram Jones purchased a dower-right in a property on Crum Creek, on which in 1802 he was assessed as owner of a grist-mill in Upper Providence, and also on a saw-mill in Marple. On Jan. 25, 1812, he bought of the executors of William Hunter, the remaining right in the mill property. In the report of Delaware County manufacturers, in 1826, it is reported, " On Crum Creek in Upper Providence and Marple a grist- and saw-mill head and fall twelve feet owned and occupied by Abraham Jones, capable of grinding twenty-five thousand bushels of grain and sawing one hundred thousand feet of lumber per annum, but not employed to that extent. These mills were owned and operated by Mr. Jones until 1834, when they were sold to T. Chalkley Palmer, who devised them to his son, Lewis Palmer. The latter is the present owner. Of the mills in the township the location of which has not been ascertained, are the following : In 1764 and continuing till 1774; Charles Lynn owned a grist-mill ; James Hunter and John Williamson each owned a quarter interest in a saw-mill. In 1770, John Calvert owned a saw-mill on Crum Creek, and in 1788, Samuel Vernon owned a grist-mill and saw-mill, and Edward Woodward a grist-mill.[bib]703[/bib]
