Page 16 - ... may fairly be considered to show the probable presence of a large and cheap supply of ore. In the Upper Carboniferous measures lying to the north of New Glasgow there are several thin layers of clay-ironstone, not apparently of economic value. In the surface-drift there have been beds of bog iron-ore observed at numerous points. These deposits have nowhere been observed of large dimensions, but would probably be utilized for furnace purposes in the vicinity of the iron-ore districts more particularly...
Page 3 - A. 1905 Dr. Edwin Gilpin, inspector of mines,* refers to the first attempts to manufacture iron early in the nineteenth century, when a few tons of bar iron were made in a Catalan forge at Nictaux ; to the production, a few years later, of an excellent charcoal iron which was largely cast into kettles and stoves, and to other subsequent operations already described. He maintains that in the Nictaux district the conditions resemble those of Germany, and that ores are presented suitable for the basic...
Page 17 - ... deposits have nowhere been observed of large dimensions, but would probably be utilized for furnace purposes in the vicinity of the iron-ore districts more particularly alluded to above. River John, French and East rivers may be mentioned as localities yielding this ore; and the following analysis is of ore from a small bed exposed in a cutting of the Glasgow and Cape Breton Railway in Merigomish, near French River : Moisture 5.500 Water of composition, 6.100 Sulphur, 208 Phosphoric acid, 384...
Page 11 - It has been opened by a few trial pits, and found in Fall Brook to be about fifteen feet wide, and to maintain this size for about a mile to the eastward. The next bed, known as the Webster ore, has been carefully trenched and tested at several points. Its thickness varies from fifteen to thirty feet, its dip being generally north at angles varying from 25 to 60 degrees. At two points it presents the following sections :— ft. in. ft. in. Ore 4 4 Ore (in four layers) 5 0 Smooth parting 00 Smooth...
Page 3 - It was not until the early part of the present century that its potential value was recognized and wide applications for its use were developed.

Page 12 - ... three to five feet. Underlying this bed. and on the line where the great bed would show its eastern outcrop, are large boulders precisely similar in appearance to the one on its western outcrop, and it is expected that it will shortly be found there. It is considered by some geologists that the three large single beds were originally one, and owe their present disjointed condition to faults and erosion. No detailed survey, however, has been made to prove the correctness of this opinion, and at...

So far, the Devonian rocks of Cape Breton have shown the greatest mineral value in iron ore, and inferentially it may be expected that future valuable discoveries will be made. In strata of this age in Annapolis County are known the valuable bedded hematites, sometimes altered into magnetites, of Clementsport and the Nictaux district. So far, similar deposits have not been...
Page 15 - ... of the county. Still further east on French River, at a horizon apparently several hundred feet higher, and considered to represent the upper part of the Marine limestone formation, there are several beds of a nodular red hematite, varying in thickness up to 4 feet. These beds have been recognized as extending for several miles.
