The route for Erie canal from Seneca river west was also explored in 1819, and the final location, from Seneca river to Rochester, made in 1821. The principal engineers were James Geddes, Benjamin Wright, and Canvass White. The annual report of the Canal Commissioners, dated January 31, 1818, gives details of the system adopted for the construction of the canal. They state that they had decided to complete the middle section first, 58 miles of which were put under contract during the year 1817, this portion being wholly on the summit level. The whole labor performed in 1817 was equal to the com- pletion of 15 miles. In indication of the easy character of the work, the commissioners state that three Irishmen finished 3 rods of canal in 4 feet cutting in five and one-half days, and that on the 58 miles under contract only half a mile required puddling. The engineer's original estimate of the cost of the middle sec- tion, completed in 1819, was $1,021,851. The actual cost was.
