Abstract
A STRIKING feature of Canada's fuel problem is the absence of coal in the central areas where population is densest, so that fuel has to be imported from the United States and Wales, or transported from Nova Scotia via the St. Lawrence-navigable only in summer. This has led the Canadian Department of Mines to give special study to the nature, preparation and storage of coals from the Sydney Area, Nova Scotia, described in a recent report by R. E. Gilmore and R. A. Strong (J. Canadian Mining and Metallurgy, p. 317; 1933). Storage in Canada is a greater problem than in Great Britain. Observations are recorded on coal piles of depth reaching 40 ft. Even at this depth, the coal was safely stored. Washing was found to reduce the tendency of the coal to heat. The ash of these coals is fusible and therefore special attention has been given to the relation between the fusibility of the ash and the behaviour of the coke from the coal, when burnt in domestic boilers.
