its waters and tho<?e of Grand river, from those of tlie Cuyahoga. 
The Mahoning as well as the Shenango, has hut a small cuireut in 
the summer season, their beds are seldom nwre than 40 or 50 yards 
wide, and their depth at that time seldom passes 5 or 6 inciies. 
The Mahoning receives no stream of any importance; Musf|uito 
Creek, which joins it on tlie leSt shore, below Wanen, is often dried 
up in Summer. The Shenango receives on its right s'loie the Pyma- 
tuning, \\!uc!i is not entirely dried up at its lowest stage. The two 
forks of the Slieiunigo join at Greenville, the western fork is called 
Shenango Creek, and the eastein, Little Shenango, the latter receives 
on its fight bank, Cro()ked Creek Musquito Creek, the Pymatuning, 
Shenango Crck, and Crooked Cr^^'^k, all rise in the swampy ground 
which here divides the waters which fall into the Ohio, from those 
which join Lake Erie. The head of Shenango Creek, and Crooked 
Creek, cross also, the Pymatuning swamp to the VV. of Conneaught 
lake. At Gicenville. the floods of the Shenango rise from 8 to 10 feet. 
From the mouth of Mahoning to Warren, the distance is about (26 
miles, in following its windings. As to the nature of its valley, its 
banks are generally flat, and favorable for digging a canal, as well 
as those of the Siicuango, and of its tributary tiie Pymatuning. 
In following from W. to E. the ground which divides the heads of 
the Big Beaver from the tributary streams of Lake Erie, it descends 
from Cuyahoga to Champion township, and ascends towards French 
Creek. Champion Swamp is thus the lowest part of this level; its 
elevation above Lake Erie, from a survey of Mr. Geddes is 54^2 
feet, and from the report of Messrs. the Ohio Canal Commissioners, 
214 feet above the mouth of Big Beaver in the Oliio; that mor.th is, 
therefore, 1272 feet above the level of Lake Erie. The rapids of 
Cuyahoga are from 97 to 100 feet above theCham])ion Swamp, and 
from 439 to 442 feet above Lake Erie. Conneaught Lake, E. of the 
head of Crooked Creek, is, from the level of Messrs. the Pennsylva- 
nia Canal Commissioners, 470 feet above Lake Erie. 
Supposing the summit level of the canal in the Champion Swamp, 
it might be fed by the waters of the Cuyahoga from the rapids. Sap- 
posing it at t'onneaught Lake or Pymatuning Swamp, it might be 
fed by the waters of French Creek, derived from Meadville, as we 
shall see below. 
The Cuyahoga, below the rapids, cannot be turned into the Cham- 
pion Swamp ; its valley, until it reaches nearest to the basin of the 
Muskingum, is divided from Mahoning fork by a ridge, whose great- 
est elevation is 208 feet above the Champion. The pond which is on 
the portage from Cuyahoga to the Muskingum is — feet above the 
Champion Swamp. — feet above Nelson's township, and about — 
feet above tlie bridge at Warren. 
The quantities of water given by these streams at their lowest stage 
in 1824, are as follows: 
Big Beaver, at the Falls, and in that part only which runs through 
the races of the Falls, gave, from instructions 
received, - . . . 88.888 ft. in a sec.
