OHI'O, the principal river in the ftate above-defcribed, 
feparating this ftate and Indiana Territory from Kentucky 
and Virginia on the fouth-eaft, and formed by the con¬ 
fluence of the Alleghany and Monongahela below Pittf- 
burgh. Both the-names, Alleghany and Ohio, have the 
fame meaning in different Indian languages 5 the former 
in the Delaware, and the latter in the Seneca, fignifies 
the Fine or Fair River; and the whole ftream, from its 
head to its junftion with the Miffiflippi, was fo denomi¬ 
nated by thefe refpeftive nations. Hence it was firft 
named by the French, La Belle Riviere. From Pittf- 
burgh it takes a north-weft courfe for about 25 miles, 
then turns gradually to the weft-fouth-weft, and, purfuing 
that courfe for about 500 miles, winds to the fouth-weft 
for nearly 1G0 miles, and at length empties itielf into the 
Miffiflippi in a fouth-eaft direction, about 1100 miles below 
Pittfburgh, and nearly at the fame diftance above New 
Orleans, in lat. 37 0 N. It is very crooked in its courfe, 
but its general direction is S. 6o° W. At Fort Pitt it 
is a quarter of a mile wide; five hundred yards at the 
mouth of the Great Kanhaway; twelve hundred yards 
at Louifville; and at the rapids half a mile, in fome few 
places below Louifville; but its general breadth does not 
exceed fix hundred yards. In fome places its width is not 
four hundred ; and in one place particularly, far below the 
rapids, it is lefs than three hundred. Its breadth in no 
place exceeds twelve hundred yards ; and, at its junction 
with the Miffiflippi, neither river is more than nine hun¬ 
dred yards wide. Its length, as meafured according to 
its meanders by captain Hutchins, is 1188 miles. 
In common winter and fpring floods, the Ohio affords 
thirty or forty feet of water from the Miffiflippi to Louif¬ 
ville ; twenty-five or thirty feet to La Torte’s Rapids; 
forty above the mouth of the Great Kanhaway; and a 
fufficiency at all times for flat-bottomed boats and canoes, 
to Fort Pitt. The inundations of this river begin about 
the latter end of March, and fublide in July, although 
they frequently happen in other months. Befides the 
waters of many creeks, the Ohio receives in its courfe 
feveral rivers; viz. the Great and Little Kanhaway, the 
Great and Little Guyandot, the Great and Little Sandy, 
Licking, Salt, Cumberland, and Tenneffee, from the eaft 
and fouth ; and the Mulkingum, the Hockhocking, the 
Great and Little Scioto, the Great and Little Miami, and 
the Wabafh, from the north. 
The rapids in the Ohio are fituated in lat. 38. 8. N. ac¬ 
cording to Hutchins’s Survey, 705 miles below Pittfburgh. 
They are occafioned by a ledge of rocks, which extends 
acrofs the bed of the river. When the water is low, the 
greater part of the rocks becomes vifible, and the naviga¬ 
tion is difficult; though there is a channel through which 
flat-bottomed boats can pafs in fafety, conducted by a 
lkilful pilot; but, in the time of the frelhets, the rapids 
are hardly to be perceived by the navigator, except from 
the fuperior velocity of the veffel’s movement; and then 
a 74-gun (hip might defcend with thegreateft eafe. The 
lituation of the rapids is very delightful; and the town 
of Louifville commands a grand view of them. Except 
at the rapids, the current of this river is gentle, its waters 
clear, and its bofom fmooth and unbroken. 
The numerous iflands interfperfed in this river add 
much to the beauty of its appearance ; but they embarrafs 
the navigation, particularly in low-water, as they occa- 
fion flioals and fand-bars. The extent of fome of thefe 
iflands is confiderable; their foil is rich, and they are 
covered with a fine growth of trees. 
Many of the families refidingin the new fettlements to 
the fouth of the Geneffee country, on the banks of this 
great river, are fupplied with Ihop-goods from veffels 
which navigate it, and are fitted-up with counters, flielves, 
and drawers, in the fame manner as are (hops on land, 
and as well ftored as many of them with all kinds of goods 
O H R 
that are in demand. On approaching a plantation, while 
they fail along the river, a horn, or conch-lhell, is blown, 
to give notice of their arrival ; when the planters, with 
their wives and daughters, repair to thefe floating-fhops, 
and feleft fuch things as they require, and make pay¬ 
ment in the produce of their plantations, fuch as flour, 
cotton, tobacco, dried venifon, the (kins of wild animals, 
&c. The ftiopkeeper, having dilpoled of his goods in 
this way, returns home with the produce he has col- 
lefted, and again renews his ftock, and proceeds on ano¬ 
ther voyage.
