Excerpt from Mineral Resources of the United States, 1927, Vol. 2: Nonmetals The production of fuel briquets in 1927 was net tons' valued at according to reports courteously furnished by the operators of briquetting plants. In comparison with 1926, the production showed a decrease of tons, but in comparison with 1925, an increase of and with 1924, an increase of As demand in 1926 had been artificially stimulated by the anthracite strike, a decrease in 1927-was anticipated. That the sales of briquets declined only per cent below the level of the strike year at a time when anthracite was in abundant supply is an indication of the progress of the briquetting industry. In fact, production in the month of December, 1927, which amounted to tons, set a new monthly record, exceeding by tons the maximum monthly production of 1926. As shown by the following table, the decrease from 1926 was con fined to the Eastern States; on the Pacific coast and in the Central States production in 1927 showed an increase of about 9 per cent.

Excerpt from Mineral Resources of the United States, 1926, Vol. 2: Nonmetals A sharp increase in both quantity and value of product marked the manufacture of fuel briquets in 1926. This infant among the mineral industries of the United States now supplies nearly a million tons of excellent household fuel that has a value at the producers' plants of eight and a half million dollars. In comparison with 1925 the production of net tons in 1926 represents an increase of 19 per cent; in comparison with 1923, the increase is 43 per cent.

Excerpt from Mineral Resources of the United States, 1924, Vol. 2: Nonmetals Parish, La., which, however, will not be worked or some time. The agreement between the American producers and the Sicilian Sulphur Consortium, described in Mineral Resources for 1922 and 1923, has apparently aided the Sicilian producers. Prior to the World War the annual production of sulphur in Sicily averaged over long tons. The production during and since the war has decreased materially, owing largely to the increased competition for European markets by chea ly produced American sulphur from Louisiana and Texas mines. T e historical table on page 3 shows the tremendous increase in recent years in the exports of sulphur from the United States. In 1922 the production of sulphur in Sicily had dwindled to long tons, but in 1923 it increased to long tons, and in 1924 it amounted to long tons. From 1880 through 1903 an average annual production of long tons of sulphur was made, starting with over 500 tons in 1880 and approximating tons in 1903.
