Gains in Explosives and Sulfur as Indexes to Recovery
700
A HEIGHTENED activity in the production of two quite unre lated commodities, explosives and sulfur, affords a good index to general recovery in the last twelve or fifteen months. Ex plosives (not including ammunition or fireworks) are in demand chiefly for coal mining and construction work on highways, rail ways, dams, etc., while sulfur finds its great use in the manufac ture of sulfuric acid, which plays such a necessary part in chemi cal and other industries. Both registered good gains in the latter part of 1933, and the greater rate of production has con tinued in the present year.
600
Production of explosives is marked by seasonal trends, the highest point of the year usually being reached about October, corresponding to greatest activity in coal mining. Last year the pick-up began in June and July and the record for new orders (figures for new orders are practically the same as those for pro duction and shipments) in the second half of the year went 21 per cent beyond the total for the like period of 1932, although they were still somewhat below that for the second half of 1931 MILLIONS OF POUNDS 40 35 30 Z5 20 ,5

SuiiFTiR PRODUCTION (TEXAS ONLY) 1928-34: States production is given by the Bureau of Mines as 1,406,063 long tons, 58 per cent more than in 1932 but 29 per cent less than the average production for the five years 1928-32. For 1932 and immediately preceding years, Texas production of mineral sulfur represented practically the entire output of t h e country. I n 1933 Louisiana companies produced approximately 321,000 tons, and the Texas output represented only about 77 per cent of the total. The proportion in 1934 is unknown. N O T E : Quarterly statistics heretofore issued by the Department of Commerce, presumably covering total U .

This gain was a continuation of. the upward tendency in the latter part of 1933, which brought the year's total for Texas to approximately one million tons, or some 23 per cent over the 1932 output.
