here about one hundred yards; its depth from twelve to twenty feet. 
It opens into the lake by a safe and straight channel, in no place less 
than ten feet indepth. This channel is secured from the deposition 
of moveable sand by two parallel piers, about one hundred and eighty 
feet apart, extending from the shore, on each side of the river, one 
thousand two hundred feet into the lake. ‘These works were erect- 
ed by the United States, and completely answer the contemplated 
purpose, forming one of the most safe and commodious harbors on 
the lake, accessible in any state of the wind or weather. A small 
light-house, on the extremity of the eastern pier, enables vessels to 
enter the harbor with safety during the night. ‘These structures do 
credit to the enlightened policy of our government, and to the fidelity 
and skill of the officers and engineers by whom the work was exe- 
cuted. ‘T'wo locks, each of six feet lift, the chambers of which are 
twenty five feet wide and one hundred feet long, having eight feet 
depth of water on the mitre sills, connect the canal with the river, 
and admit the largest class of sloops and schooners which navigate 
the Jake, to pass from the river into a basin, of nearly a quarter of 
a mile in length, with a medium breadth of one hundred and twenty 
feet, and a depth of eight feet. The dry docks are so constructed, 
as freely to admit lake vessels and canal boats to pass into them from 
this basin, for the purpose of receiving repairs. ‘The economy, ex- 
pedition, and safety with which these repairs are thus made, greatly 
encourage and facilitate the commercial operations connected with 
canal navigation. From this basin, the canal ascends the valley of 
the Cuyahoga, on the eastern side of the river, twenty four miles to 
the Peninsula, where it crosses to the western side ; thence along the 
western side of the river ten miles, after which it leaves the valley of 
the main river, and ascending that of the Little Cuyahoga and the 
outlet of the summit lake four miles, it reaches the north end of the 
Portage summit level at Akron, thirty eight miles from Cleveland. 
On this division, there are forty four locks, overcoming a total ascent 
of three hundred and ninety five and a half feet, twenty one of which 
are within three miles, and sixteen within a mile and a half of the 
north end of the summit level.” 
“The length of the Portage summit level of the canal is about 
nine miles. Its elevation is three hundred and ninety five feet above 
the surface of Lake Erie, fowr hundred and ninety one feet above 
the level of low water in the Ohio at Portsmouth, seventy eight feet 
higher than the Licking summit, and nine hundred and fifty nine feet
