tons of coke. This coke analyzes low in ash, sulphur and phosphorus, and is therefore extensively used in blast furnaces. The value of coke in the manufacture of low phosphorus pig iron depends on the percentage of phos- phorus in the coke. As the manufacturers have to meet an analysis of .08 to .085%, phosphorus in the pig iron, the phosphorus content of the coke must necessarily be very low. The Hillman Coal & Coke Company exports coke chiefly to Mexico and South America for use in copper smelting, although some coke has been exported to Italy and France for use in foundries and the manufacture of pig iron. The Hillman coke is well suited to export pur- poses, since coke for export must contain the lowest per- centage of ash consistent with proper structure. The ash content must not be excessive, for if it is, rail and ocean freights will impose a prohibitive cost upon the delivered product. UNITED STATES STEEL SUBSIDIARIES In the eighteenth annual report of the United States Steel Corporation, for the fiscal year ended December 31, 1919, the production of coke by its subsidiaries, which operate chiefly in the Pittsburgh district, is placed during the twelve months at 15,463,649 tons, of which 5,933,056 was produced in bee-hive and 9,530,593 in by-product ovens. These figures compare with 9,962,408 tons pro- duced in bee-hive ovens, and 7,795,233 tons made in by- product ovens in 1918, or a total of 17,577,636 in that year. Coal mined by the corporation in 1919 totalled 28,893,128 tons, against 31,748,135 in 1918. The total sum expended during the year 1919 on all its coal and coke properties was $12,958,647.86. Naturally enough, in the coal and coke center of the world, there are very many important corporations and firms engaged in the business of mining and selling these staple articles, indispensable in the world’s manufactories. To enumerate them all is practically impossible in the
