ground over which the canal will pass, marked out the route. At the
commencement of this, they find a very convenient situation for the
summit-pond, which' may be formed by a very small dam across the
Huron, which from estimates by actual experience, can be constructed
for $300, with an ample supply of water at all seasons of the year.
With this expense, the summit-pond will be perfectly secure from floods.
" It is found by actual measurement of the fall of the Avater the whole
distance of the contemplated canal, that it "will be seven feet and six
inches. The whole ground over which the canal will pass is bottom land,

and of the easiest kind of aquateneus earth for excavating. The whole
distance is three miles, and entirely of the above description of earth.
From excavations actually made in the same kind of earth, it is found
that the excavation may be made at an expense of six (6) cents a square
yard, and at this rate a boat navigation of four feet deep and 30 feet
in width may be made at an expenditure of $1,500 per mile, and consequently
the three miles of excavation may be made for the sum of
$4,500. Add to this the dam and the excaA'ation of the summit-pond,
.$300, equals $4,800. It is believed that tAvo locks Avill be necessary—
one at or near the summit-pond, and one at the entrance of the canal
from the river, at an expenditure of $300 each; to which add the above
