"The mean velocity of the current of this river is about two miles an hour, and is in a middling state of the water, uninterrupted with falls, impeding the navigation, from Morgantown to its mouth, a distance of one hundred miles; thence upwards the navigation is frequently interrupted by rapids, but is navigable however for small crafts for fifty or sixty miles further. The west branch in high water is navigable for fifteen miles, and communicates with a southern branch of the Little Kenhawa, by a portage of eight miles." According to _The Navigator_, such cereals as wheat, oats, barley, rye, and buckwheat were already raised to "great perfection" in the valley of the Monongahela. It was a soil especially adapted to raising exceptional wheat crops and Mr. Cramer informs us that the flour made from Monongahela Valley wheat sold for two dollars more per barrel in New Orleans than Kentucky flour. Apples and peaches were staple fruit crops of the Monongahela country and these fruits were not infrequently made into brandy. Peach brandy was a luxury in the South and sold at a dollar a gallon. "ALLEGHENY "This is a beautiful, large and navigable river, taking its rise in Lycoming county, P. within a few miles of the head waters of Sinemahoning creek, a navigable stream that falls into the Susquehanna river, to which there is a portage of 23 miles. Thence pursuing a N. course passes into New-York state, winding to the N. W. about 20 miles, turns gradually to the S. W. enters Pennsylvania, and meandering in about that direction 180 miles, joins the Monongahela at Pittsburgh. "Few rivers and perhaps none excel the Allegheny for the transparency of its waters.... "Its mean velocity is about two miles and a half an hour. In its course it receives many large and tributary streams; among these are the Kiskimenetas, Mohulbuckitum, Tobas, French creek, &c. French creek is navigable to Waterford; thence to Lake Erie is but fifteen miles portage. To render the communication more complete the legislature of Pennsylvania have passed a law for the erection of a turnpike between Waterford and Erie. Another communication to lake Erie is by way of Chataughque creek and lake; here is a portage of only nine miles, and affording ground for an excellent waggon road. We understand a ware-house is already established at Chautaughque lake. The navigation by this route is said to be the best of the two. At the mouth of a creek, also called Chautaughque emptying into lake Erie, a town has been recently laid off called Portland nine miles from Chataughque lake. This town is about thirty miles below the town of Erie, and ten below the line between Pennsylvania and New-York, John M'Mahon proprietor."
