No feature In a^teamyaoht Is ot nioro Im¬ portance than the engine. So much depends upon the rellablo uncTqulet working 01 the machinery that It Is by no menus an easy matter to fulfill all the conditions required In a yaol t's motive power. Indeed, In the majority of yachts, although In other re¬ spects they may be almost perfect In their appointments and In many cases.fitted tip regardless of expense, there is generally much room for Improvement In the engine, the pounding nnd vibration of which, In a greater or less degree, communicatee a coi • stant tremor to the boat, which is pnrtlci - larly annoying to the nerves of those on board. One of the moBt successful marine engine? now In use Is built by the Colt's Patent Flie Arms Manufacturing Company, and known as the "Colt Disc Engine." Tho engine bo- COLT DISC ENGINE FOR YACHTS. From t it Industrial World Steam yachts may be roughly divided Into three classes, namelvi racing machines, or boats constructed without regard for any other consideration except speed — such boats, Indeed, having hut little claim to the tltle'ot yacht, which, strictly speaking, Im¬ plies a pleasure boat; steamyachts proper, or steajners constructed with a due regard for all the conditions necessary In u pleisure boat, namely, comfort, safety, elegance and reasonable speed; and combined steam and sailing yachts. In which both canvas and steam pawer are available, and In which In some Instances the steam power is only con¬ sidered ns an auxiliary. * Allowing for the comparatively small ad¬ vantages or disadvantages 4lue to more or less perfect models, the speed of a boat Is said to depend upon the relation of tho avail¬ able power to the displacement or weight of a boat and Its contents. Thus, in order to obtain Increased speed, either the weight of both hull add iqachluery must bo reduced or the capacity of boiler and engine Increased tho latter u'- ternntlvendd- ing.dfcourse, to the weight.

She carries -a- 20- hnrse power disc engine, making from 350 to 400 revolutions per minute. Dili Higher first season she made several extended cruises In Long Island Sound, and subsequently visit¬ ed Now London and Newport, making \ the latter place her headquarters for a con¬ siderable time. Later In the same season she steamed through the Erie canal, and cruised for several weeks on Lake Erie, re¬ turning afterwards to New York. During the whole of this season the engine was not once opened, and when examined the fol¬ lowing spring, there wus no Indication of weal beyond a genend polishing of the sur- A PHILOSOPHER'S GOOD ADVICE. "Our Duty In the Cause of International Peace"' was the snb|ect of an address by Gen. Francis A. Walker at Smith Femolo college, Northampton, Miisp., last week. It closed as follows: "Letns remain as we are without weapons of offense. Let our title be the 'Unarmed Nnlions. For one. while respecting tho sentiments of those high officers of the navy and those members of Cungtesslnnal com¬ mittees who feel themselves responsible for the defensive condition of the country, and while entertaining no strong antipathy to ' the building of a tew fast cruisers, to carry our flag upon the seas, I trust never to se.o a floating castle, with a 24-Inch plate and 100- ton guns, built lor the set vice of the United SIiUcf.

Viewed in tlie light of racers they aro to a great extent successful, but the disproportion which exists between tho powci and the weight Involves a degree ol vibration which is annoying to passengers and very wealing to both hull anil machinery. - On tho score of safety also this boat is open to criticism.

The Lbndon Lalicot gives some timely hints about beginning utit-ol-door bathing. If the weather be clifl'y , It says, or theie be a cold wind so that the body be iiipidly cooled at the surface nhilo undressing, it is not safe to bathe. Under such conditions the further chill of Immersion In cold water will take place at the moment when the re¬ action consequent upon the chill of exposure by undressing ought to occm', and this sec ond chill will not only delay or altogether prevuht the reaction, but convert the hath tiom a meie stimulant to a depressant, end- lug lu tho abstraction ol a huge atnouiit of animal beat and congestion ol the Internal oigaus and nerve ceuties. The actual tem¬ perature ol the' water does not allect the question so lunch as its relative temperature as compared with that ot the sin oundlng air The aim must be to avoid two chills, llrst, from, the air, and leeoud from the wa ter, a'nd to make sure that the body Is In such a condition as to secure a quick reac¬ tion on emerging from tho water, without relying too much on the possible efl'ect ol friction by rubbing. It will be obvious therefore, that both weutlicr and wind must bo carefully consldeied bofoio bathing is be¬ gun, and that the state of theoiganlam as regards fatigue and the force of the circula¬ tion should also bo considered, not merely m regards the general habit, but tho special condition when n bath Is to be taken. These precautions aro eminently needful in the case of the young or weakly. eulng sell-i onlldence on tin part of the peo¬ ple ulll lead them to demand that freedom iron* conscription in d win taxes be not con¬ ditioned upon expatilallun ' Ho sure the demand will he made.
