The future of Canada lies in its breadth. With a known length of 3,000 miles from ocean to ocean the vital question for Canada is how far north her territory may prove habitable.
Significant cropping results have been obtained along the Mackenzie water system north of the Sixtieth parallel of latitude, which bounds the four western provinces of the Dominion.
