On the Hand, in South Africa, pebbles of quartzite that weather out of the " Banket ” or conglomerate are extensively used, and it is possible that rounded pebbles of dense cherty-looking rhyolite, a rock rich in silica, such as occur in considerable abun dance along portions of the Maine coast in the Penobscot Bay and Eastport regions, could be used for these purposes. SULPHUR. Sulphur furnishes an instructive example of the capture of the domestic market by the American producer. In 1903 the United States imported 191,000 tons of sulphur for consumption and pro duced only a few thousand tons in Louisiana, Nevada, and Utah. Last year the imports of sulphur for consumption amounted to only 22,005 long tons, valued at $448,504, whereas the value of the im ported sulphur in 1903 was more than $3,700,000. In 1903, more over, we exported 89,221 tons of sulphur, valued at $1,599,701. mak ing the balance of trade in our favor last year $1,151,197. The sales of domestic sulphur last year amounted to 311,590 long tons, valued at $5,479,849, and a large quantity of unsold sulphur is still at the mines. This immense increase in the sulphur industry is due to the successful operation of the F rasch process in Louisiana and Texas, where the industry has already reached the point of having its output limited only by the demands of the market. The imports of sulphur come mainly from Japan and Italy and are almost wholly entered at the Pacific ports. The production of pyrite in the United States does not, how ever, show the same gratifying ratio of growth. In the last decade it has increased from about 200,000 tons to 341,000 tons, but the im ports of pyrite have more than doubled in the same period, and last year amounted to 850,592 long tons, valued at $3,611,137, or more than twice the domestic production. It is evident that foreign pyrite is the controlling factor in the market, the production in America being insufficient to supply the demand. The principal States mining pyrite are Virginia, California, Wisconsin, Ohio, Illinois, Georgia, Indiana, Missouri, and New York. The imported pyrite comes chiefly from Spain, in which the principal deposits of pyrite occur. The imported Spanish ore is admirably suited for making sulphuric acid. Closely connected with the production of sulphur and pyrite is the sulphuric-acid industry, which now utilizes to some extent the sulphur that formerly went to waste in the air as smelter gases. The by-product acid made last year had a value of $4,346,272. This source of sulphuric acid is capable of much larger utilization, the production of sulphuric acid from smelter acid being limited only by the demands of the market available.
