284 Bulk Cargo Carriers The S. S. Atlantic, built at the yards of the Fore River Shipbuilding Cor- poration, Quincy, Mass., is the first of the duplicate vessels "Atlantic" and "Pacific' building for the Emery Steamship Co., of Boston. She is a steel screw steamer constructed with machinery aft to the design of George Simpson, naval architect, of New York City, and accorded the highest class in Lloyds registry. The vessel is designed to carry lumber and general cargo between ports on the Atlantic and Pacific coasts via . Panama canal. The principal dimen- sions are as follows: Denes over all, 405 it. 9 in; length between perpendiculars, 388 ft.; THE MARINE REVIEW holds, each operated by large twin hatchways fitted with De Russett patent covers. The cargo holds are exceptionally large and practically free from obstructions, the only pil- lars fitted being one in the middle of each hold. The vessel is therefore well adapted for carrying lumber or bulk cargo such as coal, grain, tc. The inner bottom plating has been made exceptionally heavy to withstand the bumping of grab-buckets. Arrangement will be made for car- rying a large deck cargo of lumber and a port is fitted on each side through shell forward between the upper and forecastle decks for con- venience in handling long logs. The vessel will be rigged with three LAUNCHING THE ATLANTIC, AT FORE RIVER FOR THE EMERY STEAMSHIP CO. OF BOSTON breadth molded, 54 ft. 4 in.; depth molded, 31 ft. 8 in. The vessel has a straight stem, semi-elliptical stern and a single steel upper deck, full poop, bridge house amidships and top gallant forecastle. Accommodations are provided in the midship house for the officers and wireless operator, with saloon, pantry, etc., and on bridge deck is the cap- tain's suite and chart room, with the pilot house over same. The long poop encloses quarters for the firemen, seamen and petty of- ficers, and in the Liverpool house on the poop deck are arranged the quar- ters for the engineers, with officers' and engineers' mess, galley, etc. The hull of this vessel is of the single deck type with a deep double bottom for water ballast extending all fore and aft from collision bulkhead to collision bulkhead. The cargo space is sub-divided by transverse watertight bulkheads into three cargo pole masts and two king posts, twelve 5-ton and one 25-ton derrick booms being fitted for handling cargo.. The winches, nine in number, are of Lidg- erwood Mfg. Co.'s make. . Steering gear, operated by telemo- tor, windlass and capstan of the most up-to-date type will be fitted. The propelling machinery consists of a vertical, inverted, triple-expan- sion engine with cylinders 25, 41 and 68 in. diameter, having a stroke of 48 in., supplied with steam at 190 lbs. pressure from three single-ended, coal-burning, Scotch boilers, 13 ft. 9 in. diameter by 11 ft. 10 in. long, fitted with heated forced draft on the closed ash pit system. The propeller is of the built-up type having a cast iron hub and four cast steel blades. .A. 25-ton evaporator will be in- stalled, also a 1-ton refrigerating ma- chine. The living quarters through- out the vessel will be provided with steam heat. years July, 1914 A complete electric plant will be in. stalled consisting of a 15-k. w. Gen. eral Electric Co.'s marine generating set with a combined generating anq distributing switchboard, ete, com. plete, to supply current for one 18- inch searchlight and lighting system throughout the ship, including running and signal lights. Fire Proof Oakum -- By reason of having originated the different grades of plumbers' oakum, as well as being the first in the Amer- ican field with machine spun marine oakum, the George Stratford Oakum Co. have earned the reputation of be- ing the leaders in all new things in the oakum line. This firm has now put on the mar- ket a product never before produced and but seldom, if ever before, thought possible--an oakum which is fireproof, It is the result of long experiments and fills a need long unsatisfied. Oakum has been used for many for the caulking of window frames to make them weatherproof. In fact, very few windows are abso- lutely weatherproof without its use. It has always, however, had the draw- back of opposition, as many people would not want to put an inflammable or quick-burning material in frame, slow-burning or even fireproof build- ings. Finally, the building department of New York City prohibited its use for this purpose in all buildings of ' mine stories and over, which buildings, according to the building code of that city, must be of fireproof construc- tion. The window frames of such buildings, however, must be caulked to make them weatherproof, and Stratford's fireproof oakum is the an- swer. The regular marine grades of oak- um can be fireproofed by Stratford's process, but both the chemicals used and the process itself are necessarily expensive, and this cost added to the prices of the marine grades make this impractical. Besides this, the chem- icals would partially, at least, destroy the preservative quality of the tar in these grades and this fireproofing has not therefore as yet extended into cakum for marine work. The Maryland Steel Co., Sparrow's Point, Md., has been awarded con- tract for two new 12,000-ton colliers for the Panama canal, at a cost of $985,000 each. These vessels are to be of the same type of the eight col- liers already built at that yard for the navy, and there will probably be four more vessels built for the canal. similar
