Coal Carriers

Fig. 33 Self-Unloading Collier Coalfax, Built in 1927

The industrial part of Eastern Canada is without a local supply of coal and the entire supply for both domestic and industrial use is imported, a large proportion of the imports coming from the U. S. ports on Lake Ontario and Lake Erie. About one and a half million long tons annually are shipped through the canals and several vessels have been specially equipped for the trade. These vessels have not generally been built for this particular trade but have been converted from ordinary bulk vessels by the fitting of self-unloading equipment mainly of the clam bucket and belt conveyor type.
