A Most

interesting exhibition of naval and submarine engineering has been opened at the Agricultural Hall, London, the chief feature of whieh, af ter many f ears that the pressure of the water could not be overeóme, is a glass tank, sixty feet in circumference, wherein divers can be scen working, ciad in grotesque submarine armor. The exhibition contains a vast number of models of patenta, all deeply instructive. There are Ufe raf ts, sea messengers, lighthouses, engines, boat lowering and ship raising apparatus and thousands of other ob jeets. The visitor can compare the lines of the Chinese junk with the latest Atlantic steamship, or that imperial failure, the Livadia, with the latest racing cutter, or the Mississippi threedecker with a steel clipper tea ship. In Edinburgh, Lord Rosebery has opened the International Fisheries Exhibition, which is as interesting and complete as that to which reference has just been made. It affords a complete insight into the ways and habita of big flsh aud little fish and into the various methods of transferring them from their native waters to the frying pan.
