this place much business is done in boat and ship building. The "Monongahela Farmer," and other vessels of considerable burden, were built here, and, laden with the produce of the adjacent country, were sent to the West-India islands.[20]
Eight miles farther is McKeesport, situated just below the junction of the Yohiogany with the Monongahela. Many boats are built here for transportation and the use of those who emigrate to the western country. The place is growing in business, and most probably will rise into considerable importance.
{35} Having received the Yohiogany, and waters from several creeks, the river winds its course, with replenished stream, till it unites with the Alleghany below Pittsburg, where it is about four hundred yards wide.
Braddock's Field is at the head of Turtle Creek, seven miles from Pittsburg. Here that brave, but unfortunate General engaged a party of Indians, was repulsed, himself mortally wounded, and his army put to flight, July 9, 1755.[21]
The Alleghany River, by the Delaware Indians called "Alligewisipo,"[22] rises on the western side of the mountain from which it derives its name. Its head is near Sinemahoning Creek, a boatable stream that falls into the Susquehannah; to which there is a portage of twenty-two miles. Another branch tends towards Le Boeuf, whence is a portage of only fifteen miles to Presq' Isle,
