by the old Hodge plant fifteen years ago. The high and intermediate cylinders are fitted with piston valves and the cylinder with a triple three cylin- low ported slide valve. pressure All GALLEY OF STEAMER Jj. Hi, ders have deep pistons and it is worthy of note that neither the piston valves nor the high pressure nor the inter- mediate pressure pistons * have any packing rings, only deep removable fol- lowers, and as a matter of fact, no indications of taken place during several seasons, as. observed on former engines. Narrow packing rings of the Kendall type are fitted on the low- pressure pistons. All valves ate operated with Stephenson link motion and with a simple rocker wear have arm for the high-pres- S sure valve.® Metallic packing of tre Garlock'... make 4s fitted on all valve stems and piston rods. ahe (ait -pimp is fs worked from the high- pressure cylinder cross- . head and is 36 in. in diameter by 14 in. stroke, fitted with a trunk 24 in. in diameter. All valves have am- _ ple area and are very accessible for quick overhauling. The bilge pump is 6 in. by 12 in. and the cooler pump is 4 in. by 12 in. both driven from the air pump beam. The feed pump is of the independent, simplex, horizontal, double acting, pot valve type, 12 in. - 7% in. and 16 in, The fire pump is of the usual under- writers' type, built by Fairbanksy Morse -& Co., horizontal, duplex, double act- .

The connecting rods are 8 ft. 6 in. long between centers, with brass box SELF-STOWING ANCHORS, STEAMER J. nse SHEADLE, 69 on top and babbitted cast steel boxes at the lower end. The crank shaft is of the built-up - type with cast steel arms shrunk on. The crank shaft is 12 in. in diameter supported in four babbitted journals, GALLEY OF STEAMER J. H.

The thrust bearing is braced to the bed plate and has six driv- ing collars giving a pres- sure per square inch of 4o Ibs:, average working pressure. A The outboard shaft is 12 in. in diameter enlarged in the stern bearing to 1234 in; The -béaring is-4 ft. long, lined with lignum vitae. The propeller is of the sectional type, t4 it, 3:1, in diameter and with a cir- cumferential pitch of 14 ft. 3 in., at the boss 13 ft. and a developed. area of 79 Sq.ft, There are two boilers, 15 ft. in diameter by 11 ft. 6 in. long over-heads with a working pressure of 175 lbs. Each boiler has three 44 in. Morison corrugated furnaces: 362° 3 if. tubes" fer ternal diameter); 8 ft. between tube plates. Total heating surface of the two boilers: is 5,344 sq. ft: The grate surface is 115% sq. ft., giving a ratio of heating surface to grate surface of 46.2. These boilers are worked under the improved Great Lakes Engineering Works system of forced, heated draft, giving not only exceedingly good economical results, but also a comfort- able and cool fire hold. The fan supplying the necessary air for combustion has a fan wheel 78 in.
