This will require 62 locks of ten feet lift each. The expense of such locks as experimentally proved in several instances in this state would be about 620,000 dollars.
We have seen that on the Middlesex canal, there are 22 locks for 28 miles, which is a lock for somewhat less than every mile, whereas, 62 locks for 300 miles is but about one lock for every five miles; and the lockage of the Middlesex canal, would alone cost 220,000 dollars. It would, therefore, appear to be an allowance perhaps too liberal, to consider the cost of it as a fair criterion of the expense of canals in general in this country, and of this in particular. Reservoirs and tunnels, are the most expensive part of the operation, and none will be necessary in our whole route. The expense of the whole earth work of excavating a mile of canal on level ground fifty feet wide and five feet deep, at 18 cents per cubic yard, and allowing for the cost of forming and trimming the banks, puddling, etc will not exceed 4000 dollars per mile, and the only considerable aqueduct on the whole line, will be over the Genesee river.
