Group 13.-STONE, CLAY, AND GLASS PRODUCTS The group as a whole. This group of industries | those for manufacturing. Some data for mining or includes establishments primarily engaged in manufac- quarrying are, therefore, included in the manufactures turing from materials principally derived from the earth report. in the form of stone, clay, sand, gypsum, asbestos, etc. The manufactured products cover cement, clay products, glass, lime, concrete, gypsum products, cutstone products, abrasive and asbestos products, etc. Certain industries in this group, such as those engaged primarily in the manufacture of structural-clay products, cement, lime, cut-stone products, and ground or treated minerals and earths, operate mines or quarries located at or near the manufacturing plants and their products are used in their manufacturing plants as raw materials. Such establishments usually keep only one set of books and the same employees are sometimes engaged in both lines of work, and it is not practicable to separate the data for mining and quarrying from A census covering mining and quarrying operations separately is taken only every 10 years. The last such census for the United States was taken for 1939, and the statistics will be summarized separately in the decennial census report for mineral industries. The statistics for certain industries included in this census report for manufactures, therefore, contain for 1939 some duplication of the statistics published for the census of mineral industries. The extent of this duplication will be indicated in the report for "Mineral Industries: 1939." Change in industry classification.-The "Steam and other packing; pipe and boiler covering" industry, formerly classified in the Miscellaneous Group of industries is included for 1939 in this group.

It does not include glass cutting, beveling, bending, engraving, staining, ornamenting, or making glass labels, except to the extent to which these activities are carried on by the same establishments in which the glass is manufactured. This industry was made a separate classification at the census for 1939, and the 1937 reports were retabulated to show figures comparable with 1939. No retabulations were made for earlier years.
