And in case a section ol' canal should descend from Pittsburgh to 
the north of Big Beaver on the first, second, and third routes we 
should add about 64 feet to their lockage. 
Before concluding tiiis part of our report, we should give some 
details on other terminations proposed for tbe Ohio and Erie canal 
in Lake Erie. One is to the west, and the other to the east of those 
which we iiave analysed. 
The first joins the Lake at Cleveland. For this purpose, after 
reaching a proper height to the north of Warren, the route ascends 
from Garret's mill up Silver creek, and from thence directs itself to 
tiie rapids of Cuyahoga. From thence it descends from N. E. to 
S. y<- tiie valley of Cuyahoga, and directs itself N. N. W. thro' the 
same valley to Cleaveland. But besides the difficulties which it would 
meet in winding along this rugged valley and its rapids to Cleveland, 
the total route of the canal would thus be lengthened from 24 to SO 
miles, beyond what would be required if it ended at Ashtabula: and, 
as the rapids of Cuyahoga are from 97 to 100 feet higher than the 
Champion swamp, this section would require 194 or 200 feet more of 
lockage than the former, without the resource of more water at its 
summit level. 
Another direction has been suggested for this route, by embracing 
the northern section of tlie Ohio, and Erie Canal, with the canal con- 
tesnplated by the state of Ohio, to unite the Cuyahoga, and the basin 
of the Muskingum. The summit level of this route would be in the 
swamps of the southern line of Portage county, which afford the least 
elevated, passing between the valley of Cuyahoga, and the southern 
branch of Mahoning Creek. It is in township No. 1. X range. 
These swamps, from Mr. Benjamin Tappan, are 553 feet higher 
than Lake Erie, and 41 feet higher than the rapids of Cuyahoga. 
To fulfil this object, the line of the Ohio and Erie canal should, 
from Warren, be directed through one of the soutlvern branches of 
the Mahoning creek, to the swamps in Portage county, considered 
as a summit level. This, however, cannot be supplied, except from 
the upj)ei' Cuyahoga, wiience a feeder of 35 to 40 miles in length, 
and requiring much extra embankments, should be traced from a 
point, elevated 41 feet at least above the rapids. 
By this direction, the northern section of the Ohio and Erie ca- 
nal wouid be no more lengthened than in the preceding supposition, 
when its summit level was at the rapids; but its summit level would 
be 41 feet higiier, and its lockage from 276 to 282 more than by 
the Champion swamp route. And its feeder being obliged to as- 
cend 41 feet higlicr than the rapids, it is unlikely that the Cuyahoga, 
at such a level, would give water enough to feed the canal, on one 
side to Warren, and on the other to tiie valley of Cuyahoga, below 
the falls, and also to supply tlie lockage on the summit level. 
A third direction has been suggested, with a summit level at the 
rapids of Cuyahoga, from thence, tiie line would follow^ the right 
side of the valley of Cuyahoga, to a point 5 or G miles below, from 
whence it would turn to Clcvt'larid, lca\iugto its west the ravine of
