OF EAST RIVER, PICTOU, N.S. 163 
They are of samples selected principally from beds considered important from their extent 
or convenience to transportation facilities. Their value is merely that of their being the 
first attempt at representing the composition of this mineral over a considerable tract of 
ground in Nova Scotia; and the point which is brought out, is of their comparatively non- 
magnesian character, except in the case of some of the lowest beds. They are arranged in 
ascending order, and their numbers correspond with those marked on the accompanying 
sketch map :— 
(1.) Sunny Braz Limestone.—Color bluish, with seams of white and brownish 
calcspar, and occasional coarse grains of siliceous matter. Some parts of the deposit show 
obscure fossil marks.
