304] was cut just abaft of the boilers, or what is the same thing, just forward of the engines, so that these vitals will be 42 ft. further apart in the new vessel, if such she may be called, than in the old one. In order to build a 42-ft. section into her it was necessary, of course, to pull the forward and'after hulls 42 ft. apart. This was accomplished by merely pulling the bow section 42 ft. for- ward, the after section remaining stationary. The methods em- ployed were very similar to those adopted in launching. Three FORWARD SECTION OF SEVERED STEAMER CITY OF BUFFALO. launching ways were built under the forward section, one on the port side, one on the starboard side and the other in the center. - The ways were made slippery by the liberal use of linseed oil and tallow and were so constructed as to form a combination of sliding and stationary ways. Then by means of jacks and wedges the weight of the section, approximately 1,000 tons, was transferred from the keel blocks to the ways. When the power was applied the section moved along the sliding ways at the rate of about a foot a minute. Power was furnished by the shear-legs engine pulling on a cable attached to the bow of the steamer, while two powerful capstans pulled upon cables attached to either side of the vessel. These were employed for steadiness and alignment, and when at the end of forty minutes the section had been moved exactly 42 ft. it was found to be precisely in line to the measurement of a six- teenth of an inch. The addition of 3-ft. beam to this vessel while she is being lengthened is, of course, the most interesting part of the work. MARINE REVIEW 45 lery deck. The entire work is to cost about $175,000, but this in- cludes some improvements and alterations in the vessel other than the additional length. Trimming tanks are to be installed to take the place of the chain barrels that are rolled across the deck when a change of trim is required, the ship is to be redecorated and there is other miscellaneous work of a minor kind to be done. VESSELS FOR FISHERIES PROTECTION. When the fishing cruiser which the Dominion government is now building at the yard of the Polson Iron Works, Toronto, is finished the piratical fishing companies which cross the boundary line will probably stay well within their own preserves. The new cruiser will be a flush deck vessel, having a ram bow and elliptic stern of a somewhat similar type to the smaller cruisers in the Brit- ish naval service and she will be faster than any fishing tug on the lakes. Under forced draft she is to make 16 knots or better than 18 miles an hour. There is to be a commodious deck house near the foremast, containing reception room, chart room and galley with a bridge above it extending from side to side of the vessel. The vessel will be schooner-rigged with jib-headed foresail and mainsail. The hull will be of open hearth mild steel, capable of withstanding all the tensile, cold and temper tests of Lloyd's and the vessel is to class 100 At at Lloyd's. The. cruiser's dimensions are: Length on load water line, 176 ft.; beam, molded, 22 ft.; depth from top of keel to top of main deck, 14 ft. 3 in.; draught, loaded with 50 tons of coal, 8 ft.; bunker capacity, 75 tons. She will be fitted with two sets of triple-expansion engines having cyl- inders 1314, 22 and 36 in. diameter by 21 in. stroke, supplied with steam from two Scotch boilers, 1114 ft. in diameter and 13 ft. long, built for a working pressure of 200 lbs. and fitted with forced draft. The vessel will have eight watertight bulkheads. The ac- commodations for officers and crew are all arranged below the main deck and are well provided with light and air. In the matter of auxiliary machinery she will have a steam steerer of ample ca- pacity, a complete electric light outfit of sixty incandescent lights and a powerful searchlight. The vessel will have a very handsome appearance and is entirely the product of the Polson Iron Works' staff, the government accepting her without the slightest modifica- tion. She will be ready to go into commission early in the sum- mer, and is expected to attain a speed of 12% knots under natural draft at 850 I. H. P., and, as noted above 16 knots under forced drait at 1,800.1. Hi. B. A cruiser that is being built by Vickers, Son & Maxim of Barrow-in-Furness, England, for the protection of Atlantic coast fisheries is to be 200 ft. long, 25 feet beam, 14 ft. deep and of 10 ft. draaight. She is to be electrically lighted throughout, and fitted ith a very powerful search-light, and is to carry a crew of about en all told. A FERRYBOAT FOR VANCOUVER, The Polson Iron Works, Toronto, is building a composite double-ended steam ferryboat, intended for the carriage of horses, wagons and passengers across Burrard inlet, British Columbia, DOMINION CRUISER FOR FISHERIES For about 50 ft. forward and aft of the new center section on both sides of the vessel all of the plating will necessarily have to be re- moved and some of the frames changed so that the 14%4-ft. addi- tional beam on either side, beginning at the new section, may be gradually reduced, running fore and aft, until it works into the bow and stern sections that need no change. In this way there will be no evidence when the work is completed of the vessel hav- ing been cut for additional length. To all appearances she will be a vessel built for 42 ft. more length and 3 ft. more beam than she had when she was launched. Of course the vessel's stability is very much increased by the additional beam. Mr. Kirby says he is fully satisfied that the change will give the City of Buffalo an increase of 50 per cent. over her present freight capacity. The great increase in passenger accommodations will not come alone from the new middle section. The plan of a double tier of staterooms on either side of the gallery deck, which has proven successful on the Detroit-Buffalo boats is to be applied to the City of Buffalo while the work of lengthening her is under way. The City of Buf- falo now has only one line of staterooms on either side of the gal- paOE at Se aa eet eh ia Reged eon CoE Se iy SS a ly iene Pl en PROTECTION ON LAKE ERIE. [Butlding by Polson Iron Works, Toronto. for the North Vancouver Ferry Co. The steel work for this ves- sel will be fitted up complete in Toronto, then taken down and re-erected at Vancouver, where it will be riveted up and the woodwork and equipment completed. The firm has had much ex- - perience in this kind of work and is well equipped for it. The dimensions of the vessel are: Length over all, 148 ft.; beam over hull, 28 ft.; beam, extreme, 45 ft.; draught, 6 ft. 2 in., with a capacity for twelve double teams and 600 passengers. The ves- sel will be fitted with one set of fore-and-aft compound engines, having cylinders 14 and 28 in, diameter by 20 in. stroke, and two Scotch boilers, 71%4 ft. diameter by 10 ft. long, built for a working pressure of 150 lbs. : ; The Polson Iron Works is also constructing a fast river barge for the Roman Catholic Mission in the Peace river district. She is 80 ft. long, 15 ft. beam and 5 ft. draught, having fore-and- aft compound engines, 7 and 14 in. diameter by 10 in. stroke, equip- ped with a Fitzgibbon boiler. The steel work will be fitted com- plete, then. packed up carefully to be re-erected, planked and completed when it arrives at its destination. y
