The St. Lawrence canals can be destroyed, as Mr. Chamley observes, by the Americans, without their being obliged to land a man in Canada; whilst by the Ottawa route gunboats could proceed from the St. Lawrence to Lake Huron in less time than they would now require to get to Lake Erie. It is not to be overlooked, however, that the higher latitudes through which the canal would run, expose the waters to a longer frost and necessary cessation of traffic. The advantages of the route to New York and to other North-Eastern States of America, can only be gained by completing the proposed Cooknawoogo Canal, between the St. Lawrence and Lake Champlain, and it is doubtful whether the jealousy of the Americans would not prevent their furthering a project which would confer great benefits on the Provinces, even though their refusing to do so might deprive them of certain advantages. This line would, in fact, give us or the Canadians an admirable interior communication, and at the same time confer military, political, and commercial benefits on the Provinces, the extent of which cannot be easily foreseen. Mr. Galt admits that there may be jealousies, though he protests there should not be, and calls to mind the opposition of Mohawk Dutchmen, the Frenchmen of Detroit, and others, to the Erie Canal. If the plans for improving the communications which have been suggested should ever be developed, the valley of Red River would be reached without much difficulty, and land as good as that in the unsettled portions of Iowa and Minnesota would be opened to the British emigrant. In the valleys of the Saskatchewan and Assiniboine, Canada possesses a vast north-west of her own, enjoying a mild climate, which contains, according to one of the witnesses whose opinion is cited by the Committee, 500,000 square miles of fertile land, capable of sustaining a population of nearly 30,000,000 of people. It has been ascertained beyond doubt, that the tract between the North and South Saskatchewan on the east is exceedingly fertile, and that no intense cold prevails throughout an enormous region of rich prairies on cretaceous and tertiary deposits. It is scarcely possible for us to conceive what an enormous expanse of fertile land lies to the east of the Rocky Mountains, about the sources of those rivers; but there are too many witnesses of unmistakeable veracity to render us sceptical concerning the beauty and capabilities of these regions. Could the poor emigrant be carried to these fertile districts, instead of sinking into the rowdyism of American cities, or beating down the rate of wages by competition, he would find at least a comfortable subsistence, even if he were unable at once to obtain a profitable market for his labours.
