44 docks commission and other construc- tive agencies in city, state and con- tiguous trade territory having com- munity of interests, will seek to double the population by increasing oppor- tunities for a livelihood at the Ala- bama seaport, As a_ great first important direction, L. Bedsole, of the Mobile cham- ber of commerce, has_ proposed as the major activity for the new fiscal year a complete survey of all factors entering into and definitely affecting the commerce of this city and those trading points at home and abroad with which Mobile has, or seeks, business contact. His plan has been adopted. The task of committees now at work is that of consolidating and making fully effective all that the chamber of commerce and its co-workers for Mobile heretofore have achieved: The building of the port terminals, deep- ening the channel to the sea, canal- ization of the rivers, construction of step in this President J. HE first tanker to be con- | structed on the new bracketless system of construction devised by Sir Joseph Isherwood and named BriTIsH INVENTOR in his honor, suc- cessfully completed her trial trip on July 8. This, likely to be epoch making tanker was built by Palmers Ship- building and Iron Co., Jarrow & Hebburn on Tyne, England, for the British tankers Ltd., London. Her length is 480 feet, the breadth is 58 feet and the depth is 34 feet 3 inches. She has a dead-weight capacity of 10,- 700 tons on 26 feet 6 inches draft and is classed in Lloyds 100 A 1. Machinery is located aft and con- sists of one triple expansion steam engine with cylinders 28 x 46 x 76 inches in diameter and 51 inches stroke. There are three oil burning boilers of scotch type 15 feet 6 inches in diameter by 12 feet in length. The total heating surface is 8250 square feet and the working pressure is 180 pounds per square inch. Ample auxiliaries have been fitted to meet the owner’s special require- ments of a 10-inch oil pipe line of double all-around system. There are two large horizontal duplex brass- fitted oil pumps, 12 x 10% x 410 inches each to discharge 150 tons per Bracketless System Tanker Completes Successful Trial Trip MARINE REVIEW the bridge across Mobile bay; all these, and more, have been accomplished, or are on the way to accomplishment. To obtain full benefit from these im- provements is the big job. Manufacturing sites are offered for lease on portions of the state docks property not soon to be required for improvement. Hydro-electrical power from Muscle Shoals and the plants on the Coosa and Tallapoosa rivers will soon reach Mobile over high tension transmission lines which will be completed in Sep- tember, or sooner. Water borne raw materials for manufacture can be cheaply assembled - from the mineral districts of Alabama, the salt, sulphur and oil fields of Texas and Louisiana, the phosphate beds of Florida and the nitrate mines of Chile. To bring such practical advantages together in the form of tangible, work- able and financible entities is the goal toward which all good Mobilians are working with energy and eagerness. hour. Also one extra large pump 20 x 14 x18 inches to discharge 250 tons per hour. Besides the above there is a small ballast pump and an oil fuel transfer pump. A speed of 11 knots was attained, fully loaded, on the trial trip. In reports received from the trial of this vessel it is stated that the bracket- less system of construction has ab- solutely eliminated vibration even when going full speed astern. De- flection measurements taken during this trial are believed to be less than ever attained in a similar vessel. One dry tank carefully examined after the trial was found in perfect con- dition. It would seem from this trial, therefore, that this method of con- struction so lately initiated by Sir Joseph Isherwood has demonstrated in practice what the inventor and other experts considered might reasonably be expected. The BritisH INVENTOR directly after the trial, was taken over by the owners and sailed on her maiden voyage for the East. It will be in- teresting to receive further reports of the performance of this vessel on account of the application to its construction for the first time of this new system of construction. In the August, 1926 March number of MARINE REVIEW a complete and illustrated account was given of the bracketless system of construction.

Orders Received The Haskelite Mfg. Corp. Chi- cago, has received a number of orders for its products for use on ship board among which is the roof panels in deck houses and cabins of an 83-foot cruiser building for W. C. Rands, at the Defoe Boat Works, Bay City, Mich., and panels for hulls of the Merchants and Miners. vessels building at Newport News Shpibuild- ing & Drydock Co. Wall and door panels in writing and smoking room for the same ships and for bookcase and gun _ lockers on the_ yacht Ropert Law will also be of this material. Haskelite and plymetl has been ordered for the two ferryboats for the Key system Oakland, Calif., by the Moore Drydock Co. The ferry FisHers Isuanp building at Wilming- ton, Del. by the Bethlehem Shipbuild- ing Corp. will also use this ma- terial. State room partitions, pass- age way bulkheads and built-in lockers and ends in deck houses of the three boats under conversion to diesel at the Fore River plant of the Beth- lemem Shipbuilding Corp. will also be built of Haskelite products. Settlement was approved by _ the shipping board in the amount of. $65,000, as payment to the owners of the S. 8. WoopFietp in collision with the shipping board steamer DANVILLE May 6, 1921.
