MAY 15, 1902. Controlled by = LIQUID FUEL FOR SHIPS. * The subject of this paper is not in any sense new. ‘The use of liquid fuel has been known for many years to be mechanically possible, and the Transactions of this In- stitution contain many important references to the question. The late Admiral Selwyn was an enthusiastic advocate and an eloquent exponent of the special advantages of liquid fuel for ‘vessels of war. The use of this fuel on the Caspian Sea began in 1870, and is quite the recognized custom in about 200 vessels. The fact that the vessels navigate in fresh water, and can, therefore, afford an un- limited supply of steam for pulverising the fuel without any risk of undue incrustation to their boilers is an im- portant factor. ‘The Russian law, however, prohibiting the exportation of liquid fuel has been the dominant fac- tor in the confinement in the use of liquid fuel at sea to the Caspian for at least a generation after its successful use there has been demonstrated. Whilst the advantages of liquid fuel, and the possibility of its successful mechanical use, have been generally ad- mitted, little or no progress in its application had been made outside the Russian inland sea just referred to, and the reason of this stagnation has been mainly of a com- mercial character. ‘The supply of fuel outside Russia has been but nominal, and no general application was possible, unless both war and mercantile vessels could be assured of continuotis supply from year to year, and unless that supply were’ as regularly accessible at as frequent and convenient oiling stations throughout the world as already exist in the case of coal fuel, and at a cost proportionately as low. Such a condition of things never became pos- sible until the recent discovery of large supplies of oil suitable for fuel, first in Borneo and Burmah, and quite re- cently in ‘Texas and California. It is to be regretted that the only:one of these sources of supply that lies in. British territory is that of Burmah. The whole aspect of the question, whether regarded by the Admiralty, the shipowner, or the naval architect, has been changed by the assurance of continuous supplies of liquid fuel, and it becomes necessary to treat the question, not only as of practical importance, but of urgency to those responsible for the highest efficiency of fighting and carrying ships. ‘The British Admiralty has determined to exhaustively test the use of this newly-resuscitated means of evaporation, and the reference to the question by the First Lord in his recent memorandum is a clear indication of progressive policy—a policy which is understcod to ex- tend to trials not only in destroyers, but also in three cruisers and one battleship: ‘The Italian Admiralty has been pursuing the question for some years, even before large supplies were assured, ‘The German Admiralty have used liquid fuel on the China station for many months in lieu of coal for auxiliary purposes on board ship. The Hamburg-American §. S. Co. have fitted four steamers for liquid fuel in regular use. Danish shipowners have or- dered the building in Germany of two steamers to burn liquid fuel; and some twenty vessels under the British flag are now running regularly under liquid fuel; whilst at least a dozen are building with suitable fuel apparatus included in their design. It may be expected that the supply to these stations will be drawn as regards the ports east.of the Suez Canal from Borneo and Rangoon, and as regards those west of the canal and in South America from the Texas fields; South African stations being neutral as regards the heavy charges of the Suez Canal, and therefore likely to draw their supply from Borneo or ‘Texas with equal economy. The South American stations will no doubt be supplied from the Texas and California fields. *(Read at the spring meetings of the British Institution of Naval Architects, by Sir Fortescue Flannery, M.P..

Dredging contracts on the lakes deluged Senator Hanna with telegrams this week, almost demanding that the ap- propriations for a dredge for Cleveland be stricken from the river and harbor bill. The messages came from many different dredging concerns, also Cleveland firms. It is too late to strike out this section of the bill. The provision in question passed the House and was concurred in by the Senate without amendment. ‘This renders it exempt from either elimination or amendment by the con- ference committee of the two houses, to: which the meas- ure has been referred. ‘Iherefore Senator Hanna would be unable to comply with the directions of the dredgers, even were he inclined to do so. But the Senator regards the provision referred to as a proper one. ‘The proposed dredge will practically pay for itself within a year, accord- ing to the War Department engineers, who have figured that dredging which*now costs the government between goc and 38c a cubic yard, could be done for between 7c and 8c. There is no possible excuse forthe contractors not mak- ing their wishes known monthsago. Maj. Dan C. Kingman, Corps of Engineers, U. S. A., stationed at Cleveland, has repeatedly announced his intention of securing a large, powerful and well ‘equipped dredge for his district, and the subject matter has been treated at column length time and again. ‘The act of Congress granting the appropriation for a dredge reads as follows: “The Secretary of War is authorized to cause to be pur- chased or built, a suitable dredge for use in the improve- . ment and maintenance of the harbors upon Lake Erie, at a cost not to exceed $175,000, to be paid for from appropria- tions made or authorized for the harbors mentioned in this paragraph, and in amounts not exceeding those hereafter mentioned, namely: From the amount authorized to: be expended for improving the harber at Toledo by provid- ing a straight channel through Maumee river and bay, under the River and Harbor Act of March 3rd, 1899, $40,000; from the appropriation for Sandusky $40,000; from that for Cleveland, $40,000; from that for Fairport, $25,000; from that for Ashtabula, $20,000; from Conneaut $10,000, and in case the total expenses of the said dredge shall be less than $175,000, a proportional reduction. shall be made from the amounts to be charged to each of said harbors.” ——_——— en “THE BOILER MAKER AND SHEET METAL WORKER,’’--A GENEROUS OFFER. The “Boiler Maker” is a monthly journal and stocl< list devoted to the trade, and established: in 1842, by Joseph 'T. Ryerson & Son, Chicago. In the contents of the April number just now before us, we find the following solid sense and generous philanthro- pic offer for the betterment of the trade: “In the last three years a considerable number of the older boiler manufactureres have passed away, not only in Chicago, but throughout the country. They were all men who combined mental, with physical strength, which qualities were necessary to make them the masters over their fellows. They all began in the ranks of journey- men. But now their successors may be striplings in body, but giants in mind. We do not hesitate to make the prophecy, that the greatest success will be found in those concerns that embrace in their organization the largest degree of technical knowledge. Experience will develop skill. Muscle is needed less every day; machinery does all but think, and the better the machinery the better the “thinker” must be, and how to supply the demand for educated foremen or superintendents is a source of much thought to us, i “In the early pioneer days of boiler manufacturing in,the West, of which Chicago was the center, Joseph ‘I. Ryerson was the wise counsellor and friend to many. Credit was then the chief need and it was freely given. While that need may occasionally exist, it is fortunately rare now, but there is a crying demand for intellectual aid on the part of the sons of both masters and men. We wish there was a more delicate way of indicating our desire in this matter than in print, but of the thousands that read this, there may be one that will give the needed sugges- tions, and this is our excuse for using the medium of the Boiler Maker, In grateful appreciation of the prosperity which has always been given us, and in memory of the name and spirit of the founder of this house, we stand ready to con- tribute $1,500 a year toward scholarships, or other sources of. knowledge, dealing with steam engineering and the © fabrication and erection of sheet metal in all forms. It should be available alike to the ambitious rivet boy, to the journeyman who would arise from the ranks, or even to that son who would succeed his well-to-do father. “The details which are necessary for the wise use of this offer we falter over, but with the knowledge which the bare fact affords, we feel assured some plan will be forthcoming ~ to enable us to make the “Ryerson Scholarships” a means of inspiration and benefit to many, in years to come.” Nothing further than a perusal of the foregoing, with the knowledge that the house has been in the trade for upwards of half a century, is necessary for any reader to draw rightful and righteous conclusions therefrom. For our part, we think that there ought to be more of the Joseph ‘I. Ryerson & Son caliber floating around in other branches, as’ well as the boiler making and sheet meta working industry.
