318 does not know of this and the fore- men are powerless in preventing the putting in of rivets in these holes because as a rule the riveters are fo'- lowing up close behind the reamers. The mold system of work creates a greater percentage of unfair holes than the old style of lifting the plates from the ship which, of course, increases ie cost Of reaming, The extra cost in reaming is a small matter compared to the advantages obtained by the mold Each THe Marine REVIEW as per rule. The shipbuilder as a rule the Kennebec river between Bath and _the steel paddle 'boxes, a storeroom Woolwich. The hull and machinery of the Fer- dinando Gorges were designed and built entirely at the Bath Iron Works. She is 243 ft. in length over all, 240 ft. long. on deck, 72 ft. beam over guards, 47 ft. molded beam, and 17 ft..6 in. deep. She thas four water tight bulkheads. There is a comb'ned length of trackage of 720 ft., there lbe- ing three tracks on the deck. | The ferry has independent side wheels 29 ft, in diameter with buck- ets 3 ft. wide and 8 ft. long, sheathed with iron. The wheels, like the re- mainder of the vessel, are of espe- cially heavy: construction, she being obliged to cope with ice a large part of the year. Each wheel is driven by a double engine with two cylinders of 26 in. diameter by 36 in. stroke. These engines are located in her hold and the power is transmitted to the pad- dles by pinions 4934 in. in diameter on the crank shafts through gear wheels on the paddle shafts 16 ft. in diameter. The crank shafts are of 1014 in. diameter and the paddle shafts are 12 in. -in diameter. The Gorges is fitted with four sin- gle-ended Scotch boilers 13 ft. 6 in. diameter by 12 ft. 7%4 in. long, and there are three Morrison furnaces. The working pressure is 150 pounds. boiler is fitted with an inde- ee fie 7+. system and a tool like a combined reamer and countersink must be a great saving in time at the same cost as compared with the changing of tools to do countersinking. NEW FERRY FERDINANDO GORGES. The Bath Iron Works, Bath, Me., has recently completed the steam car ferry Ferdinando Gorges for the Maine Central Railroad's service on PEG LTO: pendent circulating pump of the du- plex type, 442 mm x 23) in, = 4 in: one circulat'ng pump 9 in. x 9 in.:; one 10 in. x 17 in. x 15 in. vertical double- acting twin air pump; one 10 in. x 6 in. x 10 in. duplex fire pump and two 714 in. x 4% in. x 10 in. duplex feed pumps. The condenser is 5 ft. in diameter and 9 ft. long, A 7% kilowatt generator has been installed, equipped w'th a Curtis tur- bine, for supplying eleciricity for lighting, | September, The only structures above deck are for. life preservers and a lavatory for the use of the crew. A steel bridge has been erected at each end of the steamer with a pilot house in the cen. ter of each. The bridges span ay three tracks and are connected by a fore-and-aft gangway for the conyen- ience of the officers and crew. The vessel is strong enough to car- ry the heaviest rolling stock of the Maine Central railroad, as the three tracks are supported by: sx heavy girders supported by pillars and ryp- ning the entire length of the boat with the exception of the boiler room, where the girders span the boilers transversely. In the engine room fore and aft girders of long span are built in over the engines. There is a rudder at each end of this double ended boat, which is op- erated by a steering wheel in the p'lot house at the opposite end. Each rud- der is connected to a steam steering engine made by the Hyde Windlass Co; of Bath. The valves of. these engines are worked by shaft and gear transmission to their pilot 'house wheels. The rudder on the forward end is to be locked by means of a fork operated by screw gear on the deck. The ferry is provided with the usual - locking devices for holding the vessel fast to the transfer bridge apron and there are four h'tching winches of the Hyde windlass type. A hand capstan was also supplied by the Hyde Windlass Co. Especial care was given to the de- sign of the steamer, especially at the ends, owing to the fact that she must be an efficient ice crusher. She has ibeen fitted with two 20-ft. life boats and a 14-ft. working boat, anchor and chain, besides miscellaneous require- ments of the United States Steamboat Inspection service, all of which 'have been furnished complete by the build- ers. TORPEDO BOAT DESTROYER PARAHYBA.
