by Mr. Wolvin for St. Lawrence river trade and are actively engaged in that service, but as they are available for the ore trade, they have been classed as bulk freighters with an average capacity of 3,000 tons each on 18-ft. draught. During 1902, the lake ship yards launched 41 vessels, of which 32 were bulk freighters (two of them barges), two passenger steamers, three pack- age freighters, two car ferries and two vessels for salt water service. These 32 bulk freighters have a carry- ing capacity of 171,910 tons on a sin- gle trip, or 3,438,200 tons in an ay- erage season of 20 trips. The par- ticulars of vessels launched during 1912 will be found in the table pub- lished on this page. THE MARINE REVIEW New Dredge for Rangoon Wm. Simons & Co., of Renfrew, launched Nov. 28, with machinery on board, a Simons drag suction hopper dredger for Rangoon, built to the order of the Rangoon port commis- sioners. This vessel is fitted with a suction and discharge pump capable of raising and discharging 2,000 tons of material per hour. Triple expansion surface condens- ing engines are fitted for driving the propellers or pumping outfit, as may be required. Steam is supplied from two cylindrical multitubular boilers constructed for a working pressure of 160 lbs. per sq. in. The main centrif- ugal pump is connected, to a suction frame fitted in a central well at stern, and powerful water jets are arranged January, 1914 on the nozzle at the bottom of suc- tion frame. The hopper doors are controlled by powerful hydraulic gear, the power being supplied from one duplex set of steam pressure pumps.. The hop- per arrangements include Simons pat- ent suction apparatus which enable the load in the hopper to be dis- charged overboard for reclamation purposes, as well as through folding doors in the bottom by the ordinary method. Simons patent sand trapping appa- ratus are also provided in the hopper. These arrangements have been proved to be very effective in retaining the light material which would otherwise be lost in the overflow from the hop- per. _TABLE OF LAKE LAUNCHINGS DURING 1913 AMERICAN SHIP BUILDING CO.
