March 1, 1918. THE COLLIERY GUARDIAN. 449 1918 y^LL things Electrical in a mine should, beyond question, be of the utmost reliability. So much depends upon them. No Mine Manager or Mining Electrical Engineer can afford to take risks. Cheapness is not Economy. See to it that only Electric Cables manufactured by a Company of experience and repute are installed in your mine. Henley’s have been manufacturing Electric Cables from the beginning of Electric Cables and have concentrated all their vast resources upon them. You cannot get Electric Cables of greater reliability than Henley Cables. May we quote you next time ? We shall be pleased to do so. W T.
