We give this week an engraving of a new description of Life Boat, the invention of a Mr. Taylor, of England, and which is taken from the " London Expositor." It is called a tubular safety boat, and consists of a number of iron tubes placed in regular order, as shown in the engraving. Mr. Taylor says that he is more an imitator of nature than an inventor, and that his idea regarding tubular power was borrowed Irom the strength of a quill, the strongest combination of matter for its weight in nature. Another idea connected with his invention was copied from the construction of the Nautilus, which virtually uses tubes to rise or sink in the water, as may be desired. The inventor does not, h owe ver, limitas employment to the above purpose, but apppes the principle to the construction of larfe vessels, by which the cost of loading and unloading ballast would be obviated. He recommends vessels to takeiA water for ballast, which can be done at any port, by the use of the pumps for a short time, and it can be discharged entirely or in part by merely opening a plug attached to each tube. Two important objects are likely to be served by the invention, if it be extensively applied. The first is a saving in the stowage of water for emigrant ships, the tubes could be filled so far as might be necessary with fresh water, which could, if that were also required, be replaced with salt water, so as to preserve the weight carried by the vessel. The second consists of the facility afforded for extinguishing fires at sea—especially such fires as originate spontaneously in cargoes—for internal cocks or plugs could be affixed to the tubes, in order to secure both these objects.' The invention is also applicable to the construction of mail boxes and other articles ot nautical furniture, in order that if thrown overboard they may float securely and their contents be preserved. The only question of doubt as to the advantages of this mode of construction, is respecting its efficiency for sailing ; for a safety boat it appears to be well suited, combining strength with buoyancy, but in its applicability of form to sailing vessels, we ha ve not so much faith. It would however be a great advantage, particularly for emigrant ships, if no material objections could be urged against it, nor are there any that we know ot except the very important one with regard to the sailing qualities, which, we conjecture, would be found inferior to those of our present build of ships, constructed as they are upon certain prinoiples.
