MARINE REVIEW main compartments below the gun deck except the coal bunkers. The coal bunkers, with a maximum capacity of 1,750 tons, are arranged with reference to giving a rapid and abundant supply of coal to the fire rooms. Each ship has the following boats, provision being made for their convenient stowage and handling. Two 4o-foot steam cutters; two 33-foot sailing launches; four 30-foot cutters; 39 it can be seen from the foregoing description that they are very powerful, complete and efficient vessels and will prove most useful when commissioned and in active service. DULUTH CANAL BRIDGE. The Modern Steel Structural Co., Waukesha, Wis., has just been awarded a contract for a $100,000 suspended car transfer bridge at Duluth, Minn. This bridge will be as high from from the water as the Brooklyn bridge, allowing all vessels to pass underneath. It is 4oo ft. long between the towers and it will be erected cantilever fashion from each shore or sea wall of the present canal at Duluth, this method of erec- tion not interfering with navigation. On the lower chords of the span are two tracks carrying sixteen trucks, from which hangs a suspended car 135 ft. below, all arranged to stand the hard Duluth winds. The car is provided with two 50 H. P. electric motors connected to large winding drums, which, through the aid of steel cables wound about them, are arranged to pull the car across the canal in each direction every three minutes. The capacity of the car is sufficient to carry 200 people in the cabins and the open space on car will carry one large street car and two or three loaded wagons and teams. This structure is to be the first of its kind ever built in the United States. A similar structure, being the only one in existence, is in operation at Rouen, France. It is made of cables of light capacity and carries about fifty persons. The heavy carrying trade out of Duluth harbor has made this kind of structure necessary, as the suspended car can dodge be- 4 it oy Bena small stone =~ jand., gravel END VIEW GENERAL ELEVATION SET SUT sere Te eee em ese eee SEIT SET | MARINE REVIEW OQ SECTION C- SUSPENDED CAR FERRY BRIDGE OVER SHIP CANAL, AT DULUTH. three 30-foot whaleboats; one 30-foot gig whaleboat; two 28-foot cutters; two 20-foot dinghies; four life rafts.

This vessel will be 425 ft. long, 50 ft. beam and 38 ft. deep to the top of shelter deck. She will be fitted with 120 first-class staterooms on the main and promenade decks with a saloon to seat 220 passengers. The steamer will be equipped with two sets of triple-expansion engines with cylinders 25, 44 and 72 in. di- ameters by 48 in. stroke. She will have three double-ended boilers and three single-ended boilers, 15 ft. in diameter, with twenty-seven furnaces, allowed a pressure of 200 Ibs. Her guaranteed speed is 16 knots, but as the ship is of a very fine model, it is anticipated that her power will be sufficient to give her a speed of 17 knots in fine weather. She is to be delivered next November. Gen. E. C.. O'Brien of New York is to be made secretary of the Panama Canal Commission. He was chairman of the International Deep Waterways convention in Cleveland in 1896, and was the United States commissioner of navigation from 1889 to 1893.
