Overview

Excerpt from Descriptive Note on the Sydney Coal Field, Cape Breton, Nova Scotia The district covered by the three map-sheets numbered 133, 134 and 135, comprises part of the counties of Cape Breton and Victoria in the province of Nova Scotia, embracing the whole known area of the productive measures of the Sydney coal-field, together with a large area of the underlying rocks. The sheets above enumerated take the place of the maps of the Sydney coal-field previously issued with the Reports of Progress for 1874-75 and 1875-76. The part relating to the Coal Measures has been largely taken from surveys made by Professor J. P. Lesley, in 1862 and 1863, by Mr. B. S. Lyman in 1865, by Mr. Richard Brown, prior to 1873, by the Dominion Coal Company in 1895, from surveys made for the Geological Survey by Mr. Charles Bobb and Mr. Hugh Fletcher, and from other sources, as stated in the Geological Survey Reports. The coast-lines are generally from the admiralty charts. In this district, west of Sydney River, the contour of the ground occupied by rocks older than the Coal Measures is unusually diversified, and its connection with the geological structure is so plain that it cannot be overlooked. Four parallel ridges, the Coxheath, Boisdale, Boularderie and St. Ann hills, divided from one another by deep valleys and indentations of the sea, run from south-west to north-east and give much variety to the scenery. The height above the sea of the Coxheath and Boularderie ranges seldom exceeds 550 feet, while the Boisdale Hills have in places an elevation of 890 feet, and the St. Ann Hills of 1045 feet. The central axes of the two latter, as well as that of the Coxheath Hills, consists of syenitic and felspathic rocks, flanked by Cambrian and Carboniferous strata. The latter are found in the valleys, but the denudation to which they have been subjected has been so great that they now lie only in small patches on the hills. Brooks are numerous, and their general direction corresponds with that of the hills and longer estuaries. Those that flow northward are the largest, but none are navigable for any great distance from the sea. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
