Show Grindstones The abrasive industry in the United States showed a gain in 1911 compared with 1910, according to W. C. Phalen, of the United States Geological Survey, in an advance chapter from "Mineral Resources of the United States" for 1911. Though the total value of f.he abrasive ab-rasive materials entering the trade fell off, the decline was in the importation and not in the domestic production, which increased slightly in value. The value of the natural abrasive produced increased $119,958, which was more than enough tooffset thedecrease inthe value of the artificial abrasive produced. The fact that the decline in the total figures is attributable chiefly to the falling off in imports is a good indication of an in creasingly healthy condition in the do-1 mestic industry. The value of the abrasive materials 1 consumed in the United States in 1911! was $3,725,223, of which $3,019,803 j worth were of domestic production. In j the natural-abrasive industry gains were j shown in the production of millstone and the quarry products made in con- nection with the"m, such as chasers and drag stones, of grindstones pulpstones, of abrasive garnet, and of infusorial earth and tripoli. There was a very slight decrease in the value of the oilstones oil-stones and scythestones produced and a I small decrease in the production of pumice. pu-mice. The greatest decrease was shown in the production of emery. The annual report on abrasive published by the Geological Survey contains con-tains from year to year detailed descriptions descrip-tions of the various abrasive industries The report for 1911 includes a description descrip-tion of the millstone industry in New York and Virginia; the oilstone of Arkansas; Ar-kansas; garnet milling in New Hampshire, Hamp-shire, etc. In previous years other branches of the industry have been treated. In this way the entire field is covered every few years and the different differ-ent chapters thus serve as a5:ontempor-arv a5:ontempor-arv review of the conditions in the industry. in-dustry. The report also includes complete com-plete statistics of production of the abrasive ab-rasive materials produced in the United States, together with tables of exports, imports, etc. Natural abrasive were produced in 24 States of the Union in 1911.
