This copy of John Watson Sr.'s narrative of the 1737 Walking Purchase, written in 1815, was made by Watson's son in 1822. The elder Watson's narrative was printed with corrections and additions by the son in the Pennsylvania Correspondent, Doylestown. The volume includes the younger Watson's report of the recollections of Moses Bartram, his own commentary on the Walking Purchase, and a letter (1822) about this manuscript.
