i898.] MARINE REVIEW. 17 A FEW POINTS ABOUT GAS BUOYS. An article in the London Times of recent date describes, with the usual accurateness of that great publication, the Pintsch gas buoy, which was unheard of on this side of the Atlantic up to a few years ago, but which is now known as a valuable aid to navigation, lighting channels everywhere throughout the country, and especially on the lakes. "The Elder Brethren of the Trinity House have done much to en- courage the development of the system in England," says the Times, "Dy placing gas-lighted buoys at many important points in the channels at the entrances of the Thames, in the Solent and elsewhere. This example has been quickly followed by the Scottish light-house board, the local authorities for the Mersey, the Clyde, the Tees, the Ribble, King's Lynn and sundry other seaports, and now on the coasts of the United King- dom there are close upon 100 gas-lighted buoys in position. In the Suez canal, and in Canadian and Australian waters, these buoys are also in use. In France the lighting of buoys by means of gas has been largely adopted ment in our coast-marking arrangemnts that has taken place in the last five and twenty years, It may be that in time the majority of buoys will be gas-lighted. The door is now open for such an advance, and if it eae ae come to pass it will 'be of immense benefit to our maritime traffic.' A question often asked is, Why cannot coal gas be used in these buoys? The answer is conclusive. minating power. It is necessary, of course, to compress the gas for buoy purposes. In oil gas the loss due to compression is so slight that it is. practically immaterial. Julius Pintsch of Germany, the pioneer of this, system of buoy lighting, seems to attach considerable secrecy to the method of making these buoys. The buoy must be very strongly made to enable it to withstand the internal pressure of the compressed gas-- equivalent to that of about five atmospheres--and it must also possess the quality of being gas-tight, by no means an easy thing to accomplish when the buoy is made of riveted plates, but when the buoys are welded this FIG. 2.

In Germany, Denmark, Russia, Holland and Italy numerous gas-lighted buoys have replaced unlighted ones, and, in fact, the system 1s coming into use in all parts of the world. : "Tt is almost impossible to convey to the minds of landsmen the sense of relief experienced by an anxious mariner approaching narrow waters at night when the sights one of these gas-lighted buoys about a mile ahead, giving 'him explicit information as to his position, and it may truly be said that the development of this system is the most important improve- difficulty is overcome. The Safety Car Heating & Lighting Co. of New York, which is in control of Pintsch lights of all kinds in this country, has never succeeded in finding a concern here that could do the welding re- quired in the buoy. All the buoys are imported, and although sold en- eee to the government, a heavy duty is paid on them under the Dingley tariff act.
