A novelty in the way of carrying coal may be seen at the Harewood coal mine, at Nanaimo, British Columbia. The mines are situated at a considerable elevation above the sea-level, and the intermediate ground is covered with trees and rocks, while several deep ravines intercept the grounds. Under such circumstances, the construction of a railway would be costly and require much time, as several viaducts would be required, and the road at some places would have to make considerable curves. The proprietor of the mines therefore decided to avoid all these difficulties, on putting up a wire tramway in a direct line from the mine to the port, by means of which the ravines could be spanned without expense, and the timber on the ground could be converted into the necessary posts.

There are in all ninety-seven posts, put up to such a height that the wire spanned over them forms a softly inclining plane. The distance between them is from 150 to 250 feet. The wire rope is of the best crucible steel, specially made for the purpose, and is 6-1/2 miles in length; each post having a pair of groove-pulleys two feet in diameter, over which the wire moves. The rope is driven at the lower end by an engine of 20 horse-power, which is sufficient to drive the line when carrying 12 tons per hour.
