§ 44. Mr. Day (for Mr. David Adams)asked the Secretary for Mines whether he is aware that there is in operation in the Donbas Coalfield, Russia, a coalmine in which all the processes of coal production are carried out by hydraulic methods; and if, as it is claimed, that hydro-mechanisation will considerably expedite the work of coal winning and lessen costs, he will make inquiries into this process?
§ Mr. GrimstonYes, Sir. I understand that experiments are being made on these lines at one pit, but they appear to be in a very early stage.
§ Mr. GrimstonYes, Sir.
