78 TRAVELS THROUGH NORTH AMERICA : 
With tile Ohio,, however, it is directly the re¬ 
verse ; there are no eddies in the river; where¬ 
fore floods are found to facilitate the passage 
downwards, but to render that against the 
stream difficult. 
Supposing, however, the season favourable 
for the navigation of the Mississippi, and also 
for the navigation of the Ohio, which it might 
well be at the same time, then Louisville, in 
Kentucky, is the place through which the line 
may be drawn that will separate as nearly as 
possible the country naturally connected with 
Washington from that appertaining to New 
Orleans. It takes twenty days, on an average, at 
the most favourable season, to go from Louisville 
to New Orleans, and to return, forty; which in 
the whole makes sixty days. From the rapids in 
the Ohio, close to which Louisville is situated, 
to Pittsburgh, the distance is seven hundred and 
three miles; so that at the rate of thirty miles a 
day, which is a moderate computation, it w ould 
require twenty-four days to go there. From 
Pittsburgh to the Patowmac the distance is one 
hundred and sixty miles against the stream, 
which at the same rate, and allowing time for 
the portages, would take seven days more, and 
two hundred and ninety miles down the Patow¬ 
mac, at sixty miles per day, would require five 
days: this is allowing thirty-five days for going, 
and computing the time for returning at the
