    High-speed air-compressors for mining work, paper presented at a general meeting of the North Staffordshire Institute of Mining and Mechanical Engineers held in Stoke-on-Trent, 17 January 2016

    By Walshe J. M.

    The slow-speed compressor is giving place to the high-speed type, with its greater economy of material and space; and, where very large units are required, the turbo-compressor is supplying the need.

    Petrography and paragenesis of platinum-group minerals in Jinchuan ultramafic intrusion, northwest China

    By Li Shibo, C. Halls

    The compositions of olivine, pyroxene and chromite from the Proterozoic ultramafic complex are analagous to those of cumulate ultramafic rocks of tholeiitic origin, suggesting that the parent magma ma

    Pit-timber and its preservation.

    By Groom P.

    The wastage of timber in coal-mines that is caused by decay is very great; in fact, far greater in this country than is generally realized. Mr. E. W. Peters estimates that of the whole wastage of timb
