70 EXPEDITION TO THE 



Ohio at the mouth of Big Beaver creek.* This canal would 

 therefore require upwards of five hundred and fifty feet of 

 lockage. The question whether or not a sufficiency of wa- 

 ter can be obtained on this route is still undecided. 



The second route contemplates connecting the Muskin- 

 gum with the lake, which may be done either by the Tus- 

 carawas and the Cuyahoga creeks, or by the Killbuck and 

 Black rivers; a third division of this route purposes 

 ascending the Killbuck, continuing along the summit 

 level in an easterly direction to the Cuyahoga, and de- 

 scending that stream to the lake. These three plans may 

 be considered as parts of one general route, the preference 

 to either being a question, which it will only be important 

 to decide, after the propriety of adopting the Muskingum 

 route shall have been decided in the affirmative. The sum- 

 mit level between the Killbuck and Black river, is elevated 

 three hundred and thirty-seven feet above Lake Erie and 

 three hundred and sixty-one above the Ohio at Marietta. 

 It would therefore require near seven hundred feet of 

 lockage. The level between the Cuyahoga and Tuscarawas 

 has been found to be four hundred and four feet above Lake 

 Erie and four hundred and twenty-eight above Marietta. 

 The locks would therefore exceed eight hundred and thirty 



* We have here adopted the measurements given by the canal com- 

 missioners in their report, though we are afraid that a mistake may 

 have escaped their notice ; the height of this summit level was stated 

 by a gentleman whom we met at Columbus to be three hundred and 

 twenty-four feet, which appears more correct, for by a comparison of 

 the difference of level between Lake Erie and the mouth of the Mus- 

 kingum, the fall of the Ohio from the town of Beaver in Pennsylvania 

 to Marietta would be one hundred and fifty -two feet, if we adopt the 

 calculations of the commissioners ; whereas, upon the other data it 

 would be but thirtj-six feet, which is much more probable.
