Huntingdon Township, Lot 14, Con. J. E. Harrison, Bridgewater, Ont. XIV, Hastings Co., Ont. This deposit of talc was discovered in 1898 and is now worked, the product being shipped to the United States. No great depth has yet been attained, but the vein is reported to be wide and the shaft is in white talc on all sides. The product is equal to the best imported French talc. VII. Corundum. MATERIALS FOR GRINDING AND POLISHING. Raglan Township, Hastings Co., Ont...................Ontario Bureau of Mines. The presence of corundum in ne northern part of Hastings county was really made known in 1896 by Mr. Ferrier of the Geological Survey. The mineral found in Hastings county is essentially pure, but the susceptibility of corundum to alteration and the difficulty of getting rid of the scaly decomposition-products, are hindrances to a more profitable and more general mining and use of the mineral. Throughout the region examined, however, the corundum is, as a rule, fresh and unaltered, and it is believed that the deposits will, if properly handled, furnish a great quantity of material of uniform hardness and purity. The limit of what may be called the corundum bearing belt extends on the west from Lot 14, Con. XIV Carlow, as far as Lot 25, Con. IV Brudenell. In width it is very variable. The deposits are irregular and usually widely separated from one another. Careful research may reve il other intervening deposits, as the prospecting so far has been by no means exhaustive. In a series of experiments on quantities of 550 and 1250 lbs. respectively, conducted at the Kingston School of Mines, the corundum-bearing rock was concentrated from a content of 18 per cent. of corundum to 884 per cent. A company, incorporated under the name of the Canadian Corundum Company, has just been organized with a capital of $1,500,000, for the purpose of working corundum properties in Hastings and Renfrew counties. They are at present doing some development work, and have erected a mill at a point on the York branch of the Madawaska River. Toronto, Ont..... Ont. Bureau of Mines.

The grindstones and pulpstones of New Brunswick are obtained from the Millstone Grit formation of the Carboniferous system, which occupies a large portion of the surface of the province. As a matter of fact these materials can be obtained, more or less readily, over almost any part of the area thus occupied. The extraction is determined by demand, and by greater or less accessibility and means of transport. The cost of transportation to the Canadian markets is a serious hin drance to the greater development of the stone industry. Foreign stones are brought into Canada as ballast at a very small cost for freight. The duty imposed by the United States makes the exportation to that country almost impossible. Most of these stones are also used as building stones. Newcastle, N. B.......................... 356. Pulp-stone. ..................C. E. Fish, Newcastle, N.B. From the quarry at French Fort, near Newcastle. This stone comes from the same quarry as No. 186 (p. 195), which was opened for the production of building stone. Certain beds of the sandstone are well adapted for the manufacture of stones, of which this is a specimen, used in the manufacture of wood-pulp, for paper making. A considerable number of such stones are supplied from this quarry. Gloucester Junction, N. B. 795. Grindstone. Cumberland Basin, Joggins Station, ..... 907. Grindstone. ....R. L. Hibbard, Lower Cove, N.S. This quarry is situated about 3 miles from Joggins Station, on the line of the Canada Coals and Railway Co., and 15 miles from the Intercolonial Railway. The stone is shipped chiefly by water, a great part of it being exported to the New England States. Infusoria! Earth. Chertsey Township, Lot 15, Range V, Montcalm Co., Que. 295.
