36 NATURAL RESOURCES OF QUEBEC river and on the Kaksoak river. Another source of iron to be counted apon as a reserve are the important iron sands of the north shore of the lower St. Lawrence. Of these the most important are at Natashquan 500 miles below the city of Quebec. These iron bearing sands contain between 15 and 20 per cent of metallic iron and are estimated to contain 500,000 tons of magnetite, whilst the deposits of titaniferous ore at St. Charles, opposite Chicoutimi, are estimated to contain 5,000,000 tons. Titanic iron ore consisting of 2,029 tons valued at $8,980, was produced n the province in 1927. Chromite.—The only workable deposits of chromite known in Canada are situated in Quebec in the serpentine belt. The centre of the Quebec chromite industry is in the township of Coleraine, county of Mégantic. From 1894 to 1908 the chromite industry of the Coleraine district was quite active, but owing to the discovery of large deposits in Rhodesia and New Caledonia, the Canadian industry was closed down in 1913. Operations were renewed temporarily under war needs, but since 1925 no work of any kind has been done in the chromite mines. The world’s consumption of chromite is now increasing rapidly and the Quebec industry is expected to be reopened. The main use of chromite is for the manufacture of refractories materials. Stainless steels, which contain 12 to 15 per cent of chromium. are in increasing demand vear bv vear. Pyrites.— The shipments of iron pyrites, used as a source of sulphur for the manufacture of sulphuric acid, amounted to 13,404 tons, valued at $42,795. This pyrites comes from the concentration of the cupri- ferous pyrite ore of the Eustis mine, in the flotation mill, from which operation the iron pyrites is recovered and sold to sulphuric acid works. Electro-Chemical Industry.—Quebec has lately attained a pro- minent place in the electro-chemical industry, which is closely associated with the hydro-electric development. It centres very largely around Shawinigan Falls, although there are one or two industries located else- where in the province. Through the medium of the electric current, alumina is reduced to metallic aluminium, artificial abrasives, rivalling corundum and garnet are produced from sand and sawdust, calcium carbide is made from lime, a host of derivatives are prepared from acetylene gas, and sodium sulphide 's made by reducing salt cake with coke. The prospects for a wide expan- sion in the electro-metallurgical field are very bright in Quebec. Gold.—Alluvial gold deposits in the basin of the Chaudiére river, 50 miles south of the city of Quebec, yielded about 2} million dollars of sold between the vears 1870 and 1890. Working has been suspended
