Standard diving dress (also known as hard-hat or copper hat equipment, or heavy gear) is a type of diving suit that was formerly used for all relatively deep underwater work that required more than breath-hold duration, which included marine salvage, civil engineering, pearl shell diving and other commercial diving work, and similar naval diving applications. Standard diving dress has largely been superseded by lighter and more comfortable equipment. Standard diving dress consists of a diving helmet made from copper and brass or bronze, an air hose from a surface-supplied manually operated PUMP or low pressure breathing air compressor, a waterproofed canvas suit, a diving knife, and weights to counteract buoyancy, generally on the chest, back and shoes. Later models were equipped with a diver's telephone for voice communications with the surface.Hand operated divers air pump for one or two diversdiving, air pump

The descent of the torrent is 250 feet higher than those of Niagra, but only about fifty feet in width. The effect of the view of these falls upon the beholder is most delightful. The river at some distance seems suspended in the air, in a sheet of billowy foam. The water which first breaks over the ledge in on sheet is more and more divided as it plunges against the successive layers of rock, which it almost completely veils from view; the spray becomes very delicate and abundant, from top to bottom, hanging over, and revolving round the torrent, till it becomes lighter and more evanescent than the whitest fleecy clouds of summer." In the winter time the spray form the fall freezes in the form of a cone to a height of nearly 100 feet, and at such time the falls a greatly resorted to for the amusement of sliding down the cone with the tobogen, or Indian sleigh. The comparatively short distance from the city and the extreme beauty of the scenery along the whole route, render these falls an attractive scene for the inhabitants, who account a visit amongst their usual recreations.quebec, canada, the falls of montmorenci, moorabbin, stereograph cards
