A belt conveyor carries the stone fromthe bin to the crushers and from thence by another con-veyor to the cars. There are four railway bridges to be constructed overthe canal, one for the Niagara. St. Catharines and TorontoRailway (electric), one for the Wabash Railroad, one for theGrand Trunk and Michigan Central Railroads. These willbe reinforced concrete arch bridges. There will also have tobe constructed a number of highways and foot bridges tocarry the various roads across the canal. Several hydraulic models are being prepared at Duf-ferin Islands, near the Ontario Power Companys intakein the Niagara River. These models are based on design-;prepared by the Commission and are for the purpose ofstudying the design of the intake at Hog Island. The de-sign of the intake works will be based upon the results ofthese studies. Trade Publication Metal Molding—The National Metal Molding Com-pany, Pittsburgh, Pa., have distributed a refer
