December 8, 1916. THE COLLIERY GUARDIAN. 1097 No more unsightly buildings ! The nature of the ground in colliery districts necessitates a light weight type of building. On account of ground trouble many unsightly structures of timber and corrugated iron have been erected. There is no longer any need for this. A building erected with Hy-Rib and structural steel not only gives the desired lightness, but is far more attractive in appearance. Hy-Rib is a Ribbed Steel Lath which needs supports at 10 ft. centres only, and readily takes 2 in. of cement plaster. Its use ensures the most rapid permanent con- struction possible, the building costs little or nothing for maintenance and is superior in every way to the usual type of building. Illustration shows the Sharlston Colliery Co.’s Pit Head Buildings, erected on this principle. Send for Handbook and learn of its utility. THE TRUSSED CONCRETE STEEL C° L™ Its all in the rigid Rib. 64, CAXTON HOUSE, WESTMINSTER, S.W. --- THE ----- NEW EXPLOSIVES COMPANY Ld ESTABLISHED 1865. -------Manufacturers of --- Every description of High Explosives for Mining and Blasting Purposes.
