§ Mr. W. CARTER
asked the President of the Board of Trade what was the average output per head per shift of the German mines in 1913 and 1920, respectively?
§ Mr. BRIDGEMAN
The output per man per shift in the Ruhr mines in 1913 was 883 kilogrammes and in Upper Silesia 1,144 kilogrammes or 17⅓ cwts. and 22½ cwts. respectively. I have no figures for 1920 for the Ruhr mines; for Upper Silesia the information available points to the output per man per shift in the first quarter of 1920 being about 620 kilogrammes or 12¼ cwts. I am endeavouring to get more precise information and shall be glad to supply the hon. Member with any further figures that I may be able to obtain.
