Further infor-mation may be had from the manufacturers. Locomotives on the Boston & Maine hauling passenger trainsbetween Boston and Rockport, Mass., are using coke forfuel experimentally. The accompanying illustration, taken from The Engineer,shows one of the latest types of forced-draught steam fans,made for the British Admiralty by Messrs. Gwynne & Co., ofLondon. The fans, which are open, of the double-breastedtype, are built of steel, and are designed to combine the great-est strength with lowest possible weight. The engines, whichare very compact, are of strong construction, being suitable forrunning when desired with a steam pressure of 300 lbs. persquare Inch, and also capable of performing full duty at 200lbs. pressure. Their normal speed is 500 revolutions per min-. Engine and Fan, British Admiralty. ute. The crank shafts are of best steel, cut out of the solid,the connecting-rods and eccentric-rods of the Highest gradeof manganese bronze, and all the bearings and working sur-faces are of exceptionally large proportions, to minimize wearunder the trying tests of high speeds and pressures to whichthese engines are subjected in work. The ends of the fanspindles opposite to the engines are carried in bearings of spe-cial construction, having a universal adjustable provision toprevent strain of the spindles should the true alignment bedisturbed from any cause. Every precaution has been taken toInsure continuous lubrication of all the moving parts whilethe engines are running. BOOKS AND PAMPHLETS.
