placed fore and aft. about 8 ft. forward of cut. tling, an A frame was constructed by means of a 16 in. by 16 in. timber, placed across sliding ways and di- rectly in line with stem. From this timber a 10 in. by 10 in. shore was placed on each side of stem. Shores were spread 5 ft. 6 in. apart on tim- ber and butting against angle clips, fastened to stem. Wedges- were placed under cross timber on sliding ways, and the frame firmly wedged up. Stoppers, consisting of 15 in. by a2e in: timbers - 8 ft. 9 in. long, were placed at ends of ground ways and through bolted. These stoppers were placed 40 ft. 2 in. from end of slid- ing ways, the 2 in. of extra length being made up by placing 2 in. wood liners against stoppers, as ship start- ed to move. Power for pulling forward section of ship was furnished by two 30 H. P. double cylinder winches, placed on foundations formed 'by three 12 in. by 15 in. timbers for each winch, Outside timbers taking hold of three dock floor tim- 'bers, and center one taking two; all through bolted with 34 in. washer plates on under side of floor beams. After winches had been securely bolt- ed to these foundations, two 9 in. by 10 in. shores were placed from floor timbers to winches, thus giv- ing additional strength to take pull of tackle. The pulling gear consist- .ed of two triple block tackles,' hav- --manila .rope alls. ©The ig 5, in, blocks on winch end were fastened to a 16 in. by 16 in. timber extending across and butting against end of ground ways. This timber was se- eutely lashed with chains to dock floor timbers and braced on the way end by two shores on each side. The blocks on ship end were held by means of 134 in. chains, which were Qaclied 16° 6 ft. 18 in. hy 34. in. plates, riveted to bottom of ship and Tackles were placed 19 ft. 8 in. between cen- ters. An Extra Tackle Fitted to Stem. An extra tackle was fitted to stem of ship, consisting of a double plate, taking five rivets in stem and to which was fastened a wire pennant. A triple block tackle with 5 in. ma- nila falls was attached to this pen- nant, the other end taking the anchor rod at head of dock. 'Fall of this _ tackle was led to a winch located at compressor room, next to machine shop. This tackle was not used. "To assist winches in starting ship, three 125-ton hydraulic rams were fitted inside ship, which were operated sim- ultaneously with the two winches. TAeE Marine REVIEW The lining up process was as fol- lows: The ways were made level by let- ting water into dock to within a few feet of ground ways. At a given sig- nal, four measurements were taken by means of battens at equal 'dis- tances along each way, and from sur- face of water to top of ground ways. These eight battens were then meas- ured and, taking the longest one for a point to work from, the ways were wedged up at all points to corre- spond with it. To prove the keel was in line hori- zontally, battens were fastened to keel blocks on a level with surface of water and at intervals of 30 ft., and measurements taken from these battens to. bottom of keel. "Fhese distances were taken, before pulling, after wedging up, and after pulling, and the keel was found in all cases to be perfectly" level, horizontally. As a further proof, "several feet of water were let into dock directly after lengthening, and battens were used to measure from water level to keel, four being taken forward and four aft, at 30> ft. 'intervals. . The battens taken forward showed that -ship had pulled on a perfectly hori- zontal line, while those aft showed substantially the same conditions as - before lengthening. Proving Alignment. -- To prove alignment of keel in: a thwartship direction, vertical lines were marked on a number of keel blocks before pulling. These lines were perfectly plumb and placed 6 in. off the center of keel in all cases. After pulling the ship, the points were measured wherever possible, and the section was found to be ex- actly in line at cut, but had moved Moi. tO port. at. bow... This. was eliminated by wedging. Measure- ments taken from a line stretched fore and aft on hurricane deck alsa showed the ship to be in line. To prove whether the ship acquired a list in lengthening, two center punch marks were made on bottom plating 6 ft. forward of cut and about 13 ft. out from center line on each side. Before pulling, battens were used to measure the height from water level to these punch marks, and after pulling the same measurements were taken. It was found on comparing these 'battens that section had taken a ¥% in. list to port, which was eliminated by shor- ing up and wedging. The lining up process having been completed, the work of placing frames, etc., was rapidly advanced. January, 1910 MORAN co. TO BUILD NEW STEAMER. On Dec. 23, The Moran Co., Seattle, was awarded a contract for the con- struction of a steel steamship for the Puget Sound Navigation Co., the cost of the new vessel, to be about $175,- 000. The vessel. will be ready for service on or before June 1, next, and will be placed on the run from Seat- tle to points on the Strait of Fuca. The new vessel will be built on practically the same lines as the steamer Whatcom, now on the Port Angeles run, save that she will be of steel up to the passenger deck. She will have a speed of 14 knots an 'hour, a knot speedier than the Whatcom, and the new vessel's boiler will de- velop 250 lb. of steam against the Whatcom's 180 lb. The new steamer will have sleeping accommodations for 110 persons, and all the staterooms will be two-berth rooms, with spe- cially furnished and spacious bridal chambers. forward. A large observation room with a plate glass front will be. forward on the hurricane deck, similar in design to the. -obsérvation cabins' -of- the Princess: "boats: of . the. Canadian Pad cific railway, and the new steamer will contain all the improvements and inventions which the modern ship builders' art has brought to perfection, including wireless telegraphy. As the freight business. to be handled by the boat, in addition to the passengers, will be of importance, the construction of the vessel will fol- low lines which will permit of carry- ing a large cargo and the big 'side ports will tbe wide enough to admit automobiles and other bulky articles which may go by freight. The vessel will also be equipped for loading freight through wide deck hatches and on the foremast will be a boom capable of lifting a five-ton weight. The steamer will be built to con- form with the requirements of Lloyds and will class with that society along with the vessels constructed for use in' the English channel and, in fact, all the lines of the new steamer have been drawn to approach in construc- tion as nearly as possible, considering the trade she is to 'be engaged 'in, with the best class of English passenger steamers engaged coastwise. With her steel hull carried up over the freight deck the new vessel is expected to be able to go out in the worst weather along the Strait and keep up her schedule without interruption.
