Towns. There are already more than 125 towns and villai^- 

 es built on the Ohio. The city of Pittsburgh, at the head of it, 

 contains nearly 15000 inhabitants. Cincinnati, in Ohio, con- V^

 in Kentucky, at the falls, about 5000: Steubcnville, in Ohio a-

Branches. The Ohio receives immediately about 400 

 streams, of which 20 are rivers above 100 miles long, 54 are 

 small rivers or large creeks, and more than 300 are brooks and 

 runs. Its largest branches empty into the lower parts of the Riv- 

 er, such as the Tennessee, Cumberland, and Wabash. They 

 all flow^ in valleys similar to that of the Ohio and proportioned 

 to their size. Many of them, such as the Scioto, Miami, Ten- 

 nessee, Wabash, &c. have plains, which indicate former lakes. 

 Most of them have rapids, ripples, bars, islands, &c. and offer 

 the same phenomena as the Ohio, particularly the periodical 

 rises and falls. I shall give some account of the 20 principal 

 streams, which fall into the Ohio, in the order in which they 

 join it.
