S. W. Length 250 miles, real course 450 miles or nearly 525 

 English miles. It is a large and deep stream, navigable even in 

 summer, as far as the falls. Its lower valley is wide and shal^ 

 low, with many islands and bayous. It has five large branches, 

 such as Little Wabash, White river, Sec. This last is very 

 considerable and extends its numerous and large branches 

 throughout Indiana ; the longest is 350 miles long, one of them 

 runs parallel with the Ohio. It empties above Shawneetown. 



18. Salixe River. It flows through Illinois in a S. E. di- 

 rection, emptying below Shawneetown. Length 55 miles, rea* 

 course about 90, or 105 English miles; it is therefore the smaL 

 lestof the rivers emptying into the Ohio; although Big Blue river^ 

 Tradewater river, Little Muskingum, and Liale Scioto, are still 

 smaller and rather large creeks ; their course being less than 

 100 miles, I have not noticed them. The Saline river is partly 

 navigable and has three principal branches. 



19. Cumberland. It rises in the Cumberland Mountains o 

 Kentucky, and after watering Tennessee, returns into Kentucky 



its course being W. and N. W. about 300 miles ; real course a- W 

 bout 500 miles or about 585 English miles. It is a fine naviga- 

 ble river, flowing in a broad valley, and with many small branch. 

 es, but no large ones. It has also been called the Shawanec. 



20. Tennessee. The last and largest of the branches of the 

 Ohio. It is formed by the union of the Holstein and Clinch riv_ 

 ers in Tennessee, the former rising in Virginia near lat. 37, and 

 the second in North Carolina, within the Alleghany Mountains 

 near lat. 35. The whole course, if the Clinch river is deemed 

 the main branch, will be three hundred and fifty miles, and the 

 real course six hundred and fifty, equal to about seven hundred 

 and sixty english miles. Duck river is another large branch 0£ 

 it, and there are three others besides. The direction is S. W. 

 then west and next north, watering Tennessee, Alabama, Ken- 

 tucky, &c. and emptying into the Ohio a few miles below the 

 Cumberland, from which basin it is divided by a high ridge 

 and not far above the mouth of the Ohio. The Tennessee is a 

 very large and fine navigable river, almost equal to the Ohio in 

 size, but not in depth. Its valley is wide and has had many 

 lakes, one of them was at the Muscle Shoals, which forms now a
