The great desire is now to lengthen the shipping season. Professor Barnes, of McGill University, has made the study of ice his specialty and he is at present carrying on experiments for the Canadian government. He is of the opinion that winter navigation is a possibility. At present the government has, on the St. Lawrence, two ice-breakers, which extend the time of navigation by a few days. The ice difficulty arises where the river widens into a lake, as at Lake St. Peter. Ice forms on the sides of the lake and is blown into the current. When the banks again converge, this ice jams, soon forming a solid ice-bridge. The ice-shoves which occur in the spring are caused in the same way. The solution of the problem is to have ice-breakers always suitably situated to break these bridges as soon as they form.
