The high pressure cylin- der is driven by a plain plug piston valve, the first intermediate by the ordinary piston valve, the second intermediate by a piston Trick valve, and the low pressure by the ordinary double-ported slide valve. All of the engine forgings are of high-grade steel, and the crank shaft, thrust shaft and tail shaft are of hollow forged steel, made by the Bethlehem Iron Co. of So. Bethlehem, Pa., under what is known as the Whitworth fluid compressed system, and this shafting, before leaving their works, is all oil tempered. The propeller is 15 feet in diameter and 16 feet pitch, and made of cast steel. The bed plate is of cast iron, made in one piece, and weighs about 24 tons. There are four Scotch boilers, 13 feet 4 inches mean diameter, and 11 feet 84% inches over tube sheets, each boiler being fitted with three Morrison suspension furnaces, and the whole designed for a working pressure of 200 pounds per square inch. Each boiler is also fitted with a Learmonth purifier. The total grate surface in the four boilers is 264 square feet, and the total heating surface 9,417 square feet; NEWEST AMERICAN SHIP YARD. _ The Review appropriately presents as one of the supplements to this edition a group of scenes at the ship yard of the W. R. Trigg Co., Rich- mond, Va.--America's newest ship building plant. Eight months ago this plant was one of the remotest of possibilities. When Mr. W. R. Trigg, president of the Richmond Locomotive Works, Richmond, Va., sub- mitted in his own name bids for torpedo boats and destroyers under the authorization of the act of May 4, 1898, even he was far from sanguine of securing even a single contract. When the award was made, contracts for three torpedo boats and two destroyers were awarded to him. Then Mr. Trigg set to work with an energy worthy of the cause. The W. R. Trigg Co. was organized and the stock subscribed almost in a single evening. The old Talbott works was leased and the work of converting it into a machine shop begun, while a large force of workmen hurried the operation of driving piles for 600 feet of launching ways fronting on the James river. Even the municipal officials caught the enthusiasm and steps were at once taken to deepen the channel of the river. Meanwhile competitors of the Trigg company, who had been un- PEE eet pq Mammon mas 14s we. 0 Once or ro a ee OU Ree 41 mee oe rene 22-77 amet AL Mood es mmmeng . 5<1°" EN 2 [{_ovrmns wvr9 a ------ i beh pes 5, pase erepe wera 14 Derr é «8 STAAL Srerg Like THI FSG BBs te 5 gone toms A som wane r Smo aes 8578 © 8977 200, | 75 "ony man re mae 0+ iain Sese ge mee20 & aeeht ALAry oe * LES toes a0 at wens oman hrm nneg m7 poor inngap 1 HORE a mses serssune Reo +MY eutwwass sressene go -o © STAY TuBes 7 BWG.

Tops of the combus- tion chambers are made circular, with plate attachments for staying the back head. This obviates the necessity of using crown girders and studs. The Truscott Boat Manufacturing Co., St. Joseph, Mich., manufac- turers of vapor marine motors and high grade pleasure craft are enthusias- tic over the outlook for business. In a letter to the Review they say: "We have reason to believe that next season's business will be the best in the history of small launch building. We are at present and have been for some time past working a good force of men, and are putting on more at the rate of several every day. We have on our books orders for over twenty-five launches, in sizes ranging from 16 feet to 50 feet in length, which we will ship to all parts of the world, and which are almost exclu- sively for pleasure purposes. We are also working on a line of stock boats. The excellent outlook for next year's business has been sufficient _ to warrant our making extensive additions to our plant. In fact we have added: three buildings." The Daimler Manufacturing Co. of Long Island City, N. Y., is building the following craft: A 50-foot $7,000 auxiliary yacht for L. O. Schwencke of New York City; 18-foot $800 launch for William E. Glucek of Brooklyn; 26-foot, $1,300 launch for N. A. Pendleton of Stonington, Conn.; 21-foot, $900 launch for the Mexican Trading & Coffee Co. of Mexico City, Mexico; 33-foot, $2,000 launch for Commodore L. R. Brooks of Minneapolis, Minn.; 18-foot, $800 launch for James Kaine of Brooklyn; 38-foot, $4,000 launch for W. W. Curry of Miami, Fla. These vessels are equipped with Daimler motors, ranging from 1 to 25 indicated horse power. successiul in securing awards of contracts, raised with the navy depart- ment the question of the ability of the Richmond concern to fulfil the contracts as the stipulations stood with reference to time limitations. The department made an investigation, with the result that the contracts were ratified and the Trigg company assigned the torpedo boats Shu- brick, Stockton and Thornton and the destroyers Dale and Decatur. But the prime movers in the new enterprise had not relaxed their energy, and the consequence was that they were enabled to lay down the boats in the mold loft almost as soon as any of the longer established firms. The Trigg Co. has up to this time, of course, devoted all its attention to the naval contracts in hand, but it is also a tribute to the reputation and ability of the men behind the enterprise that contracts for mercantile tonnage are already in sight. Mr. Trigg is president of the company, Lilburn T. Myers, vice president, and W. C. Preston, secretary. The general offices, which were at first established at Room 10, Chamber of Commerce build- ing, have been removed to 1521 East Cary street. P. L. Colon, whose Claremont steam marine railway and ship build- ing yard is located at the foot of Philip street, Jersey City, N. J., has just completed three scows, each 116 feet long, 33 feet wide and 12 feet deep for the Interstate Dredging Co., and three deck scows, each 120 feet long, 37 feet wide and 12 feet deep, for Brown & Fleming. Prices on the former were $9,000 each and on the latter $6,000 each. The Cape Cod Yacht Agency at Barnstable, Mass., is building six 20-foot catboats, all from one design, for a Barnstable summer resident. The agency management has just about closed contracts for a 21-foot raceabout for Boston parties and a 30-foot cruising yawl for a New Yorker.
