THe Marine REVIEW NEPTUNE SOUNDING MACHINE. the gage is of such strength that it will stand rough handling without in- jury. It works equally well in all weather, and no special instruction or extra crew is necessary to operate. If the captain wishes, he can control the ma- chine and be sure of the exact num- ber of fathoms by personally closing and opening the cap of the gage. The approximate depth can always be. deter- mined by the length of wire out, as shown by the dial on the machine. ALLEN DENSE AIR ICE MA- CHINE. Of the many various auxiliary ap- paratus which make up the complement of the modern steam vessel those whose disarrangement would worry the cap- tain above all others are the steering en- gine, the arrangement for hoisting and lowering the anchor, the sanitary pump and the ice machine where the vessel' instead of the old: is fitted with this fashioned ice chamber. To absolutely secure the functions ot the first three additional apparatus for performing their work is always provided. To make sure of any defection by the lat- ter, in this country, the Allen dense air ice machine has mostly been used and is now after 20 years experience still the most reliable and the one which is most relied on. The. first . ones in operation in the United States naval; and im. private ser- vice since that length of ti He "Bre still doing their duty faithfully, single-hand- ed, and the large fleet of monster men- of-war which lately circled the globe provided for its men as well as; officers, fresh méat and cool water and ice every day by means of those machines, the greater number of them also hav- ing only one machine doing the whole duty single-handed: No better proof of the absolute confidence in its 'relia- bility could be had. : The new monster battte ships now commenced to be built have in addi- tion' to the meat refrigerators, other machines of the same size and kind for keeping the powder magazines at a safe cool temperature for the mod- ern powerful powders and other ex- plosives. : In) private service the large num- bers of high class steam. yachts. equip- ped with these machines, regularly fill up 'with meat in the northern harbor when they. start for a trip into the sev- eral parts of the tropics and then have no trouble to maintain their meat sup- ply in first class condition for months until they return to where they end the excursion. The reason of this confi- dence is that no gases nor high "pres- sure chemicals are used for producing the cold but common atmospheric air properly utilized in one machine, which is so built that the usual steam engineer and oiler of the vessel needs to attend only to having it turn around like any usual steam engine and no various out- side special devices are to be learned nor to be carefully adjusted. ae The air is compressed in an air com- pressor, then cooled by water, then ex. panded in a steam engine cylinder. This treatment brings the air to a temperature very far below zero. It was done more than sixty years ago, but the design of a machine for doing this in a practically useful man- ner for ships service and with never failing surety is the virtue of the Al- len dense air ice machine. AUXILIARIES OF THE NON. MAGNETIC YACHT CAR. NEGIE, The anchor handling machines and sail' handling machines, as well as anchors of the non-magnetic yacht Carnegie, building at the yard ofxthe Tebo Yacht Basin Co., Brooklyn, WN.
