THIS INFORMATION CIRCULAR contains injury and employment data for all stone quarries in the United States for the Calendar year 1960. This publication contains statistical data on injuries and employment pertinent to the stone quarries and related operations, such as the manufacture of cement and lime, rock dressing etc., but excludes statistics for clay and sand and gravel operations. Data for these commodities may be found in other Bureau publications. Reports received from the operators are voluntary responses to the Bureau's request for information; therefore, the figures may not be complete for the industry. However, since these data contribute greatly to the promotion of safety, every effort has been made to make them representative of the industry.
