formed by the size of the locks at Port
Dalhousie, which is the entrance on Lake Ontario. Two of the largest
class, in masonry, and of the best quality, have been constructed: they
are 200 feet long by 45 wide; the lift of the upper lock is 11, and of
the lower, 12, which varies with the level of Lake Ontario, the mitre
sill being 12 feet below its ordinary surface. Steamers of the largest
class can therefore go to the thriving village of St. Catherine's, in
the midst of the granary of Canada.

The La Chine Canal must be enlarged for ship navigation more effectually
than it has been. I subjoin a list of colonial shipping for 1844 from
Simmonds' "Colonial Magazine."
