asked the Secretary for Mines what was the approximate quantity of British coal submitted to oil extraction processes during the first quarter of 1935, and how this amount compared with the similar figure for 1934?

The SECRETARY for MINES (Mr. Ernest Brown)

Statistics relating to the extraction of oil from coal are only collected by my Department annually. The figures for 1934 are expected to be avail able in a few weeks.
