BUILPING NEW CRUISERS WORK OX XUltBEBS XIXE TEX rEOOEESSIXO. AXD TIIET WILL CKDOCBTEDLT BE COMPLETED WtTHIK THE TIME LIMIT T11K1R F-XTIRE SUCCESS EXPECTED. Baltimore. MtL.Ang. 0. Tbe Columbian Iron Work in this city have pushed tbe construction so rapidly on cruisers No. 6 au io that tbe fifth payment ba been signed for by the naval inspectors having charge of the work. In actra! polut of completion the now cruisers are one fifth along, aud one-fourth along If tbe material now at tho yard but not worked Into the vessels Is taken Into consideration. Over six hundred men are engaged at preseut on the two vessels, and It is plain that tbe Columbian people are cudcaroriug to make a record on them. The contract for No. 9 and 10 wa awarded to the Baltimore firm only last November, with time limit fixed at two and one-half year. A if to assist tbe Columbian Iron Works In it efforts, the steel people furnishing the plates and forgings are rushing their niitterial aloug In remarkably quick time, so riiplilly in fact that Naval Constructor W. H. Varncy, who is supervising the construction, remarked the other dsv that he Lad never seen material turned in so quickly and at the same time so free from defect or naw as in ine present instance. " I do not like to predict wucn No. 9 and 10 will be able to enter the water," said Mr. Var-ney, "but there is every reason Io believe tbat unless something unforeseen arises, there will be no delay in the completion of these vessels." I p to within tbe past few days not a check had occurred in the delivery of material. But now a hitch la being experienced over tho two stern post. The eastings for this part of the hulls are being looked out for by the bundard Steel Company, and for some reason the company bas been unable to deliver tbem within the time specified. As a consequence the material tbat Is coming In from other source 1 piling up In the yard. Iu the building of cruisers Noa. 9 and 10 the Columbian iron Works has undertaken the oon- sinicuon oi nenny an me nttings or tne vessels, leaving to outsider onlv the furnishing of material in the quantities and kind desired. Thla undertaking is something entirely new to the Baltimore hrm. and Is believed by the contractors to be the only Instance of its kind in the war-ship building now going on in tbl country. In accepting the contract tor l'oa tt and 10 the firm undertook tbe machinery construction also, and those In charge of It have constantly endeavored to keep pace with tho hull construction. Seven cylinders tn all hnvebeen cast and several pieces of shafting made ready for service whenever needed. The small brass and Iron work for hull fittings is well under way, aa the pile or finished metal here and there In the uiachlno shops -indicate. The cruisers ar9 building close alongside each other, their stems reaching well down to tbe edge of tbe Patapsco River. Viewed as they lie on the stock, tbe two vessels present almost Identically the same appearance. Their ribs, except those iu tho extreme after part, are oil in place. The stempleces are standing, and the greater portion of the longitudinal bulkhead betwevn tbe two engine rooms 1 In place on each vessel. The water-tight deck beam are more than one-half in place, but tbe plating baa been held back and will continue to be until tbe sternposu are in position. In the machine shops Mafater A Co. have at preseut some eighty-five men at work, and this force la being constantly increased. Tbe General Superintendent in charge here is Mr. J. L. Boyd. Thla gentleman bad charge of the Petrel's engines in the trial trip of that vessel. Mr. Boyd remarked the other da v that bis department waa making all its own machinery, even to tbe auxiliary engines. He believed, though, that the air pumps would lie mm based, a th contract specially stipulated for ekiplex pumps. Mr. Boyd expressed high satisfaction over the forged shaft sections which bad been received from Nashua, N. H. On the shaft bearing magnolia meUl is being used. Thisns a form of white metal which was found on tbe trial of tho Charleston and York-town to be absolutely necessary to the life of the bearing. White metal la very similar lu composition to type metal. The magnolia metal Is of English design, though manufactured in this country by agents of the home firm. A depth of one-eighth of an inch of white metal will bo exposed in all the shaft bearing of cruisers Nos. 9 and 10. " Iu addition to the cylinder tbat bare been cast, ell thehlgb-preMure (team cheat liner are In band and well advanced. Three high-pressure and two Intermediate-pressure pistons are well nigh Completed. Nearly all the small work of the air ports 1s finished, while, in fact, all of the coaling scuttles are completed except tbe galvanizing. The foundry le turning out on an average about 600 pound of brass castings per day. Each of tbe cruiser will require five boiler, designed to supply steam sufficient for tbe development of 5.400 indicated horse power a a mean of a four hours' run. In eaoh ship there will be three cylindrical double-ended and two single-ended boilers. All the boiler are of the same diameter, namely, 11 feet 8 inches. In length the two forward boilers will be 18 feet 1 luch and the after boiler IU feet 8 inches. There will be three corrugated furnace to each boner. These furnace will be aupplled by tb Continental Iron Works of Greenpoint L. f. The contract calls for 366 square feet of grate surface and 10.966 square feet of heating surface In tbe boilers of Noa. 8 aod 10. The thickness of the boiler plate wlU be one-Inch steel, in testing these boilers a pressure of 250 pound per square Inch will be applied, tbe method being to flU the boilers quite full of water, then pply beat The elastic limit of the boilers is not to be lesa than 32.0OO pounds, and they will be tested to about two-thirds their elastic limit In the placing of the boiler in each vesel there will be three boilers on one side and two on the opposite side. The weighu are equal, a the boiler vary In size, one boiler in each case being single ended. The boilers being placed fore and aft give several different boiler rooms, by virtue of the longitudinal and atbwartshfp bulkheads. These boiler rooms can only be -reached from the upper deck, thus insuring against trouble such a arose in the case of the City of Paris disaster. Forced draught la to be used, but Introduced under the grate boxes and not by menu of the closed fire room system. Tbe work which the Columbian Works have In hand bas made tt necessary for this establishment to provide Itself with many expensive and fine pieces of machinery. Strange to aay the greater number of new tool have come from W estern establishments. Chief Engineer Boyd, commenting on this remarked that tbe machinery tool now being made In Ohio and Illinol were ahead of anything of like sort in the world. " "There wa a time." taid Mr. Boyd, "when El??1nd f nrnished good tools. Then some Philadelphia firms succeeded In placing on the market most excellent machines. In fact even excelled some of the very best tool made in England. But now tbe shop to the East cannot begin tomake tool such as are made In Hamilton, Ohio, and other Western cltiea." Among some of the now machinery which ha lately been received i a new universal milling machine of the largest size, with all attach-menu, and a new twenty-tour-loch slotting machine, built by tbe Nile Tool Works. Hamilton. Ohio: a lifty-four-larb wlng twenty-eight-feet bed lathe, and a large radial drill with six-foot radial arm. These tool re of the finest make. In addition three large drill pressesare being built for the boiler shop and are nearly completed. Only recently, Itf addition to the above four portable drills with flexible shaft were re ceived, and two heavy crane erected with two chain purchase of ti.Ooti pounds aud 4.000 pound respectively.
