§ Mr. E. Brown
The china-clay industry is not separately distinguished in the statistics of employment and unemployment among insured persons compiled by my Department. For the purpose of these statistics it is included in the clay, sand, gravel and chalk pits classification. Statistics of the numbers of insured persons in that industry in July, 1937, will not be available until November next, when the information derived from this3520W year's exchange of unemployment books has been tabulated. At July, 1936, the number of insured persons aged 14 to 64 years in Great Britain so classified was 17,870; the number recorded as unemployed at 21st June, 1937, was 970.
