HC Deb 20 March 1928 vol 215 c198
22. Mr. WHITELEY

asked the Secretary for Mines whether the experiments to displace the use of the guss for hauling wheelless tubs have proved successful; if so, what is the nature of such experiments; and when are they likely to be fully adopted?

Commodore KING

I regret that I am unable to anticipate the report of the Commitee.
