In common winter and spring tides it affords 15 feet water to Louisville, 10 feet to Le Tarte's rapids, 40 miles above the mouth of the Great Kanhaway, and a sufficiency at all times for light batteaux and canoes to Fort Pitt. The rapids are in latitude 38° 8. The inundations of this river begin about the last of March and subside in July. During these a first rate man of war may be carried from Louisville to New Orleans, if the sudden turns of the river and strength of its current will admit a safe steerage. The rapids at Louisville descend about 30 feet in a length of a mile and a half. The bed of the river there is a solid rock, and is divided by an island into two branches, the southern of which is about 200 yards wide, and is dry four months in the year. The bed of the northern branch is worn into channels by the constant course of the water, and attrition of the pebble stones carried on with that, so as to be passable for batteaux through the greater part of the year. Yet it is thought that the southern arm may be the most easily opened for constant navigation. The rise of the waters in these rapids does not exceed 10 or 12 feet. A part of this island is so high as to have been never overflowed, and to command the settlement at Louisville, which is opposite

to it. The fort, however, is situated at the head of the falls. The ground on the south side rises very gradually.

The Tanissee, Cherokee or Hogohege river is 600 yards wide at its mouth, 1-4 of a, mile at the mouth of Holston, and 200 yards at Chotee, which is 20 miles above Holston, and 300 miles above the mouth of the Tanissee. This river crosses the southern boundary of Virginia, 58 miles from the Missisipi. Its current is moderate. It is navigable for loaded boats of any burden to the Muscle shoals, where the river passes through the Cumberland mountain. These shoals are 6 or 8 miles long, passable downwards for loaded canoes, but not upwards, unless there be a swell in the river. Above these the navigation for loaded canoes and batteaux continues to the Long island. This river has its inundations also. Above the Chickamogga towns is a whirlpool called the Sucking pot, which takes in trunks of trees or boats, and throws them out again half a mile below. It is avoided by keeping very close to the bank, on the South side. There are but few miles portage between a branch of this river and the navigable waters of the river Mobile, which runs into the Gulph of Mexico.

Cumberland, or Shawnee river, intersects the boundary between Virginia and North Carolina 67 miles from the Missisipi, and again 198 miles from the same river, a little above the entrance of Obey's river into the Cumberland. Its Clear fork crosses the same boundary about 300 miles from the Missisipi. Cumberland is a very gentle stream, navigable for loaded bat

teaux 800 miles, without interruption; then intervenes some rapids of 15 miles in length, after which it is again navigable 70 miles upwards, which brings you within 10 miles of the Cumberland mountains. It is about 120 yards wide through its whole course, from the head of its navigation to its mouth.

The Wabash is a very beautiful river, 400 yards wide at the mouth, and 300 at St. Vincennes, which is a post 100 miles above the mouth, in a direct line. Within this space there are two small rapids, which give very little ob. struction to the navigation. It is 400 yards wide at the mouth, and navigable 30 leagues upwards for canoes and small boats. From the mouth of Maple river to that of Eel river is about 80 miles in a direct line, the river continuing navigable, and from one to two hundred yards in width. The Eel river is 150 yards wide, and affords at all times navigation for pariaguas, to within 18 miles of the Miami of the Lake. The Wabash, from the mouth of Eel river to Little river, a distance of 50 miles direct, is interrupted with frequent rapids and shoals, which obstruct the navigation, except in a swell. Little river affords navigation during a swell to within 3 miles of the Miami, which thence affords a similar navigation into Lake Erie, 100 miles distant in a direct line. The Wabash overflows periodically in correspondence with the Ohio, and in some places two leagues from its banks.

Green River is navigable for loaded batteaux at all times 50 miles upwards; but it is then interrupted by impassable rapids, above which

the navigation again commences, and continues good 30 or 40 miles to the mouth of Barren river.

Kentucky River is 90 yards wide at the mouth, and also at Boonsborough, 8 miles above. It affords a navigation for loaded batteaux 180 miles in a direct line, in the winter tides.

The Great Miami of the Ohio, is 200 yards wide at the mouth. At the Piccawee towns 75 miles above, it is reduced to 50 yards; it is, nevertheless, navigable for loaded canoes 50 miles above these towns. The portage from its western branch into the Miami of Lake Erie, is 5 miles; that from its eastern branch into Sandusky ri ver, is of 9 miles.

Salt River is at all times navigable for loaded batteaux 70 or 80 miles. It is 80 yards wide at its mouth, and keeps that width to its fork, 25 miles above.

The Little Miami of the Ohio, is 60 or 70 yards wide at its mouth, 60 miles to its source, and affords no navigation.

The Scioto is 250 yards wide at its mouth which is in latitude 38° 22'. and at Saltlick towns, 200 miles above the mouth, it it 100 yards wide. To these towns it is navigable for loaded batteaux, and its eastern branch affords navigation almost to its source.

Great Sandy River is about 60 yards wide, and navigable sixty miles for loaded batteaux. Guiandot is about the width of the river last mentioned, but is more rapid. It may be navigated by canoes 60 miles.

The Great Kanhaway is a river of considerable note for the fertility of its lands, and still more, as leading towards the head waters of James river. Nevertheless, it is doubtful whether its great and numerous rapids will admit a navigation, but at an expence to which it will require ages to render its inhabitants equal. The great obstacles begin at what are called the Great Falls, 90 miles above the mouth, below which are only five or six rapids, and these passable, with some difficulty, even at low water. From the falls to the mouth of Greenbriar is 100 miles, and thence to the lead mines 120. It is 280 yards wide at its mouth.

Hockbocking is 80 yards wide at its mouth, and yields navigation for loaded batteaux to the Press-place, 60 miles above its mouth.

The Little Kanhaway is 150 yards wide at the mouth. It yields a navigation of 10 miles only. Perhaps its northern branch called Junius's creek, which interlocks with the western of Monongahela, may one day admit a shorter passage from the latter into the Ohio.

The Muskingum is 280 yards wide at its mouth, and 200 yards at the lower Indian towns, 150 miles upwards. It is navigable for small batteaux to within one mile of a navigable part of Cayahoga river, which runs into Lake Erie.

At Fort Pitt the river Ohio loses its name, branching into the Monongahela and Allegha

ney.

The Monongahela is 400 yards wide at its mouth. From thence is 12 or 15 miles to the mouth of Yohoganey, where it is 300 yards wide. Thence to Red-stone by water is 50 miles, by
