The mine is worked by means of a shaft ninety-six feet deep and a slope 550 feet long.--Carboniferous. 443. Coal. This mine is on the Phelan seam. The shaft in 1881 was 120 feet deep, and was cleaned out at that date. The amount of coal raised in that year was only 3,115 tons, only 12 persons being employed.--Carboniferous. 448. Column of Coal. These mines are owned by a company of Halifax capitalists, who leased an area of 1,640 acres in 1861 from Mr. E. N. Archbold of Sydney. They have been worked more or less profitably, and at one time are said to have paid a dividend of 40 per cent. to the shareholders. The area is about sixteen miles from Sydney, and is most favourably situated as regards shipment of coal. It embraces the entire land outcrop of the Hub soam, and a large proportion of that of the Harbor seam (from which the column was taken), and is also underlaid, at a depth of not more than 700 feet bolow the last-mentioned seam, by three workable seams, and at a lower depth by two others, the thickness of which has not yet been determined. The total thickness of the Hub seam is nine feet ten inches, of which the upper portion, one foot eight inches thick, being of inferior quality, is not taken out except in the main level. The Harbor seam, which is the representative of the Sydney main seam, is five feet six inches thick. The coal from both these seams is largely used for gas purposes in Halifax and the United States, and yields nearly 10,000 cubic ieet of 15 candle gas per ton. An analysis of a specimen from the Harbor seam gives--The total output of coal in ls84 amounted to 36,138 tons, giving employment...
