of the World.—The worlds production of nickel was4,197,558 pounds in 1889, and about 35,500,000 pounds in 1909. Theupper line in the diagram represents the worlds production in the sametime, and it well illustrates the increase in production. (See Plate X.)The entire production of nickel, apart from quite insignificant quantitiesobtained in Germany, Norway and the United States, comes from NewCaledonian and Canadian ores. In 1909, the supply from each of the lattercountries was 9,217,009 pounds and 26,282,991 pounds respectively. Theincrease in the worlds production of nickel has been due to the extensiveuse of nickel alloys. Nickel steel is now being used for armour plates,steel rails and for machine parts subjected to reversals of stresses, andwhere increase of strength and decrease of weight are desired. Resources of Canada.—The nickel deposits of the Sudbury districtsupplied over seventy-four per cent, of the worlds production of nickel <* Estimated from smelter production.

CONSERVATION OF MINERAL RESOURCES 419 iu 1909. The remainder is largely derived from the silicate ores of NewCaledonia. The nickel-bearing rocks of the Sudbury district, with a widthof about two-and-a-half miles, form a rude ellipse thirty-six miles longand thirteen miles broad. The ores consist mainly of a mixture of pyrr-hotite and chalcopyrite intimately associated with more or less countryrock. The nickel occurs in the pyrrhotite as pentlandite and varies inamount from two to five and a half per cent. The ore depositsare of three main types—marginal deposits, offset deposits and vein-like deposits. The Creighton mine, which may be called the great-est nickel mine in the world, is an example of a marginal depo-sit. The Copper Cliff mine is an example of an offset deposit, whilethe Vermilion mine is probably the best example of a vein-like depositand has probably been formed by hot circulating waters. Cobalt in theproportion of one to fifty of nickel is found associated with the n
