PRODUCTION

The sales of stone in the United States in 1923 were the largest ever recorded. There was an increase of 29 per cent in quantity and of 31 per cent in value. All varieties of stone showed increases.

The tables of this report give quantities and values f. o. b. at quarries and mills as far as it is possible to obtain them. Stone quarried and used by the producer is considered as sold and is included in the figures given. This report does not, however, include the stone manufactured into abrasives (grindstones and pulpstones), glass sand, lime, and cement and reported in terms of finished prod

These products are treated in the chapters on abrasives, sand and gravel, líme, and cement.
