Value of building and monumental stone (exclusive of marble, onyx, and breccia) and other classes of stone imported into the United States in 1923 • Algeria and Tunis, China, Chosen, Hongkong, India (British), and Japan. PRODUCTION BY KINDS AND STATES GRANITE Granite as a whole showed an increase of about 24 per cent in quantity and 43 per cent in value in 1923 as compared with 1922. With the exception of granite for rubble and unspecified purposes ("other stone") all the products increased in both quantity and value. The output of granite for monumental work, which during 1921 and 1922 suffered severely from labor troubles and lack of demand, increased about 90 per cent in quantity in 1923. Granite for building stone did not recover so quickly from the labor troubles that retarded the output in 1922, but there was an increase in all grades of granite for this purpose except that for rough architectural work. The report on stone in Mineral Resources for 1922 gave the names of the principal producers of granite for monumental and structural stone, and the output of several of the more prominent districts. The only tables of production repeated here are those for Quincy, Mass., and Barre, Vt., as the other districts are adequately represented in the general table on pages 213-214. Granite for paving blocks and granite for curbing, which were included among the products affected by the strike of granite cutters in 1922, increased in output 60 and 49 per cent, respectively, in 1923. Granite for crushed stone increased 22 per cent.

Monumental granite sold at Quincy, Mass., 1919–1923 a • A small amount of stone from these quarries is also sold for rough construction, riprap, and crushed stone. Monumental granite sold by the quarrymen in the Barre district, Vt., 1919-1923 Through the kindness of Mr. R. E. Mitchell, secretary of the Barre Granite Manufacturers Association, the following figures covering the entire granite industry at Barre are given to supplement the figures of production reported to the Geological Survey by the quarry men: Estimated output of monumental granite in Barre district, 1920–1923 BASALT AND RELATED ROCKS (TRAP ROCK) There was an increase of 6 per cent in the output of basalt and related rocks in 1923. Crushed stone, which is the principal product, increased 7 per cent. There was also an increase in the stone for paving blocks, riprap, and "other" uses, but stone for building purposes and rubble decreased. Under "other" is reported 85,200 short tons of "roofing granules," valued at $628,297, made from altered diabase (greenstone). Besides these "roofing granules" others of slate and slate "flour," amounting to 462,260 tons, valued at $3,268,554, were sold in 1923. |
