The coal-field of Colchester and Hants is separated from the former-described field by the Cobequid chain of hills. The coal-seams appear to be all under 18 inches in thickness. The coal-field of Pictou contains two thick beds of coal, the upper 37 feet (largely worked at the Albion mines), accompanied by three other workable beds, having an aggregate thickness of nearly as much more, separated by 157 feet of strata. The last three beds are divided by partings of inferior coal and ironstone. The beds incline at an angle of 20°; only 12 feet of the upper part of the seam are now worked. The coal is high in ash. (See fig. 36.) showing probable position and connection of seams. FIG. 36.-Glace Bay District, Nova Scotia. Richmond and Cape Breton Coal-field.-According to M. R. Brown, the productive measures here cover an area of 250 square miles, with a thickness of 10,000 feet of strata. North-west of Sydney Harbor there are four beds, containing 20 feet of coal in a thickness of 1500 feet. The respective thicknesses are 3 feet 8 inches, 5 feet, 6 feet 9 inches, and 4 feet 8 inches. There are good coal-seams at Lingan and Bridgeport; one contains 9 feet of coal-a fine coke and good gas coal. Prof. Lesley's description of the fields of Nova Scotia says the coal-beds on Great and Little Glace, Cow, and Miré Bays are of handsome size and highest quality. The beds north of Sydney Harbor are more limited in area, thinner and poorer in quality, and are reached at great depths. No. 8 Pit, Glace Bay Colliery.
