this stream alternates by sweeps. The line €Ouid not leave the val- 
ley to attain a termination at Ashtahiila. 
When the question presenteil itself, Whether the canal route might 
not rather ascend to the Cuyaiioga, and descend that vailey to Cieavc- 
]an<), the first in([uiry naturally was as to the elevation oftiic grounds 
Mr. Geddes liad not levelled up the i-apids, and we were left to infer 
its elevation from the other elevations which he measured, and partly 
from the conjectures of the inhabitants. 
He began on the side of the small lake between the Muskingum and 
the bend of the Cuyahoga, 404 feet above Lake Erie. Itis line was 
run eastward beyood Ravenna, and the ground west of the Mahoning 
was found to be 149.20 fcct above the starting point at the little lake. 
It was foujid that ike narrow falls of Cuyahoga is forty-nine feet 
above that point, from whence to the rapids, (tlie place we visited,) 
•tlic ascent is estimated at 120 feet, distance fifteen miles. Mr. Ged- 
4lcs continued his line of level from the high ground to Garret's mill, 
on Silver creek, found to be 58.80 feet below the starting point: coir- 
tjuuing on, he found the swamp in Nelson to be 37.80 
and Cham^iion below that - 21. 
58.80 
As Champion is 58.80 below the point of departure, and the Nar- 
row Falls 47 above it, and the fifteen miles ascent 120, asconjectur- 
^'d. Cuyahoga Rapid is 225.80 above Champion, and Champion is 
342 above Lake Erie; therefore, 567.80 is the elevation of this lino. 
This is corroborated thus: 
The starting point '• 404 
To the Narrow Falls - 47 
To the Rapids - 120 
571 
It is true, the number 120 is conjectural; but as tlie people cstiniat" 
«d the fall to be 150, it is set down sit 120. To this discouragement 
might have been superadded the difficult nature of the ground down 
the Cuyahoga Valley, according to Mr. Geddes' report in print. 
It is not our duty at this time to dwell on the advantages which 
Ohio may ultimately derive from local relations and elevations of the. 
Cuyahoga. It may surely be the means of forming a useful canal east- 
ward, if it cannot adequately supply a canal of the dimensions this 
Communication, prospectively considered, will require. 
Subsequently to these observations, tlie Board followed the line from 
Warren to Austinburg; thence to Paynesville and the mouth of Grand 
River. 
Returning to Austinbui'g, wc pursued the line proposed to Ashtabula, 
and viewed its harbor also; the next object was to view the summitground 
between the head of the Ashtabula and the head of the Pymatuning, a 
branch of the Shenango; tlieucc, to the head of tliat river, and down 
its valley, soutbward, to the junction oi Crooked Creek branch, whicli
