Mines and Quarries Schedules

Beginning in 1900, statistics were collected on mines and quarries.  These schedules do not include enterprises valued at less than $500; or in the case of bituminous coal mining industry, producing less than 1,000 tons; or, if not productive, in which development work amounting to less than $5,000 was done.  By 1920 the schedules list numbers of mines, quarries, wells, and plants; classification; influence of increased prices; age, sex, wages, and positions of employees; prevailing hours of labor; capital; expenses; supplies and materials, fuel, and power; contract work; royalties and rents; taxes; expenditures for development work; value of products; cost of mining and profits; lands controlled; and power used.  In 1930 the list of exclusions is different and a few categories are added.  For instance, it expands “sandstone” into sand and gravel, glass-sand, and molding-sand industries.
