Shipbuilding and Shipping Record . years is shown in statistics to have fallen from321,400,000 poods in 1904 to 249,200,000 poods in 1913.

The result isobvious, that the further construction of iron barges, unless theproduction of petroleum be much increased, must be stayed. STEAMSHIP APPLIANCES. HAMILTONS PATENT DECK FLANGE. Cable chams when rove through a hawse pipe of the ordinarypattern inflict considerable wear on the pipe especially where suchis connected with the shell or the deck platmg. This also impliesa considerable amount of friction which has to be overcome by thewindlass. Hamiltons patent hawse pipe and deck flange manu-factured by A. Hamilton & Sons, Ltd., Victoria Foundry, Cardiff,overcomes the disadvantages owhig to the presence of steel rollersat each end of the pipe. Tiie accompanying illustration sho«s the. ^^cnit-^ deck flange from which the general principle of the patent will beseen. Marine supermtendents will appreciate the consequentelimination of friction caused by a cable nmning hard on the ordinarydeck flange and as Hamiltons patent means less power andless steam necessary with a corresponding lengthening in the lifeof the windlass chain and pipe, owners will see that the extra costof installation will soon repay the outlay. The deck flange maybe fitted to existing jjipes independently of the patent pipe andeven in this case considerable saving is effected. The idea hasbeen adopted on several lines and is giving satisfaction. BRITISH KROMHOUT ENGINE.
