We will now proceed to review the residue of the At lantic rivers of the United States, from the Savannah river to Passamaquoddy bay. After surveying their na tural features, a view will then be taken of such artifi cial works, as have been executed, or projected, to fa cilitate navigation and commerce.
The basin of the Altamaha is followed by the small and unimportant basin of Ogeechee, about 150 miles in length, from north-west to south-east, with a mean width of 30 miles, comprising an area of 4500 square miles. The Edisto, and the Cambahee, augmented towards its mouth by the Camchee, from the west, rises in the small triangle between the Santee and Savannah rivers, nearly upon the line of separation between the primitive and sea sand alluvial formations.
The Savannah river basin follows rattler that of the Altamaha, than that of Ogcehee. The Savannah river has its sources in the Appalachian mountains, on the primitive, over which it flows 150 miles, on its course towards the Atlantic ocean. At Augusta it leaves the primitive, and enters the alluvial sea sand, over which latter it again flows about 120 miles, having an entire comparative course of 270 miles. The sources of the Savannah interlock with those of Altamaha, Chatahooche, Tennessee, and Santee. It is a long stream, receiving but few tributary branches, and draining a basin 250 miles in length, by a mean width of 40 miles, comprising an area of 10,000 square miles. Large vessels ascend to Savannah, 18 miles from the Altantic ocean, and boats of considerable tonnage to Augusta. It is again navi gable with boats to some distance above the falls or ra pids at the latter place.
At the mouth of Savannah river the Atlantic coast turns in a nearly north-east direction 300 miles, to the entrance of Pamlicoc Sound. In this distance, leaving Savannah river, the first inlet is that round Port Royal island, into which the Coosahatchie river is discharged. Between the Coosahatchie and Charleston bar, the Cam bahee and Edisto enter the Atlantic ocean. Neither of those three latter streams admit of extensive inland na vigation.
Ashly and Cooper rivers are still more confined in extent than the Camhahee and Edisto, but the two former contribute to produce one of the finest harbours on the Atlantic coast of the United States, that of Charleston, in South Carolina. This noble haven is the mart of an extensive tract of country, chiefly watered by the tribu tary streams of the Santee.
The latter is a river of considerable magnitude, having its sources in the Appalachian mountains, at North Lat. 36°, West Lon. 5°, from Washington City, and falliug into the Atlantic ocean at North Lat. 3:3° 12', West Lon. 2° from Washington City : it consequently runs through three degrees of latitude and three degrees of longitude, having an entire length of '250 miles by comparative courses, and draining about 11 000 square miles. The Santee is formed by the united streams of the Wateree and Congaree rivers, both otiginating in thc Appalachian mountains. The Wateree, in the higher part of its course, is known by the name of Catawba, and the Con garee is formed hy the Saluda and Broad rivers. The Santee is navigable by sloops a considerable distance above the main fork, and steam•boats ascend at high wa ter to Columbia, on the Congaree.
The Great Pedce follows the Santee in position and consequence. The Pedee rises at North Lat. 36° 30', West Lon. from Washington City 4°, and flowing by comparative courses 250 miles, falls into Winyaw Bay, 12 miles below Georgetown, North Lat. 33" 18', West Lon. from Washington City, 2°. This river drains 15.000 square miles, and is navigable with boats of 40 or 50 tons burthen near 200 miles, following the winding of the stream. Near the mouth it receives Little Pedee, and Wackimau branches, both also navigable for sonic distance from their respective mouths. The Pedee, like the Altamaha, Savannah, and Santee, originates by both its great branches from the Appalachian mountains.
Cape Fear river rises in the hilly region intervening between the mountains and alluvial sea border, at about North Lat. 36°, West Lon. from Washington City. 3°, and flowing south-east by south 200 miles, hy compara tive courses, falls into the A'lantic ocean at North Lat. 33° 50', West Lon. from Washington City 1° 05', and drains about 7000 square miles. Cape Fear river is formed by the stream of that name, properly so called, Black river, and the north-east Branch, all uniting above Wilmington. This river, having. 18 feet water on its bar, affords the best navigation North Carolina. Ves sels drawing 11 feet water ascend to the city of Wilming ton, 35 miles above the bar. Boats of sufficient tonnage for the commerce of the country, ascend in the main stream 105 miles to Fayetteville, and in the nor.n-east Branch 70 miles above its confluence withCape Feat river.
