Note 225 — MEMOIR OF THE LIFE OF DAVID RITTENHOUSE; CONTINUED, FROM THE TIME OF HIS SETTLEMENT IN PHILADELPHIA.

Now the flourishing borough of Pittsburgh, situated at the confluence of the rivers Allegany and Monongahela, which form, by their junction, the commencement of the great river Ohio.

This place, which is distant about thirty-five miles, eastward, from the western boundary-line of Pennsylvania, was the site of a fort, formerly erected by the French, which they called Fort Du Quesne; but on its reduction by the English, it was named by them Fort-Pitt; and by this name the place is still recognized by many people.
