She has had one-half liquid and one-half solid cargo on the same voyage. Raw sugar generally makes up the solid cargo. can Bureau of Shipping, and equipped to meet all the requirements of the United States steamboat inspection rules. The ship has a straight stem and elliptical stern, and is built on the Isherwood longitudinal system of fram- ing. She has two steel decks with a raised poop, forecastle, bridge, with bridge house over and a house on the poop deck. There is a double bot- tom under the machinery space divided into compartments water. The hold is divided into six tanks for carrying oil or molasses in bulk or general cargo with a fuel tank located between cargo tanks 3 and 4. The center line bulkhead extending to the upper deck divides the tanks into port and starboard compartments, with an expansion trunk between’ the main and upper decks for the full length of the tanks. The wing spaces between the main and upper decks are divided into four summer tanks. The Drixtano is rigged with two steel pole masts and two steel samson posts. Accommodations are provided in the steel deck house amidships, which is raised up on a level with the forecastle deck, for dining saloon, pantry, offi- cers’ rooms, wireless operators, ‘linen locker, deck office, bath room and house for the accommodation of the captain and the owner. A wooden house on top of this house has been constructed for the pilot house, chart for carrying feed sistant engineers, oilers and_ galley. On the lower deck abreast the en- gine and boiler casing, is located set- tling tanks, fresh water tanks, refrig- erating machine, engineers’ storeroom and workshop. Under the forecastle deck is provided a hospital with the required number of berths, a paint and oil room, lamp room, storeroom and carpenter shop. Discharge Through 10-inch Pipe The pump room, located just for- ward of the fireroom, is fitted with two cargo pumps and one stripping pump. The hatch for the pump room is ex- tended to the poop deck with a sky- light over. Access to the pump room is had by means of steel doors, one on the port and one on the starboard side through the casing. The cargo pumps are 200-ton per hour steam driven duplex brass lined double acting, ca- pable of pumping against a head of 250 pounds pressure. Control rods are installed for operating the pumps from the deck. The suction system consists of 12-inch mains running on each side of the center line bulkhead of the ves- sel with a 10-inch branch taken off to each main cargo tank. Each suction to the tanks is fitted with a flanged gate valve, brass fitted, and provided with the necessary gear for operating it from the deck, with brass plates on deck, suitably marked. The cargo pumps are arranged to name i April, 1924 draw from the cargo holds and dis- charge through 10-inch pipe running fore and aft on the upper deck on the port side with discharge outlets at the forward end, amidships and at pump room. Not only the cargo pumps, but the discharge cargo pipe, fittings, etc., are capable of pumping against a head of 250 pounds. The discharge pipes on deck are fitted with the necessary flanged gate valves and blank flanges for the hose connections. The piping in the pump room is arranged so that the pumps can either draw from the deck connections and discharge to the tanks through the suction lines or draw from the tanks and discharge through the deck connections. Strainers are fitted to the cargo lines and strip- ping line in the pump room. A sea valve with the necessary sea chest, strainer, etc., is fitted in the way of the pump room so that the cargo tanks can be flooded through the suction pipe. The deck connections are arranged so that either pump can cischarge separately or together to the deck connections. Six-inch suction pipes with the necessary flanged gate valve brass fitted, are installed in each of the summer tanks and connected to the main cargo pumps and stripping pump. A 6-inch stripping line is in- stalled in each of the cargo tanks and cofferdams, with connection to the strip- ping pump in the pump room with a discharge overboard and a cross con- nection to the main cargo discharge line, and also a cross connection to the suction line from the summer tanks. This stripping line, where passing through the fuel oil bunker, has a connection for pumping out fuel il. The cargo oil piping is of the stand- ard black wrought steel with cast iron screwed flanges. The discharge lines are of heavy pipe to stand a pres- sure of 250 pounds. The hatches to the tank holds are Sy constructed that they are suitable for the carrying of either molasses, oil or general cargo. The hatch covers are of steel, suitably stiffened and bolted to the hatch covers with oil tight joints. On top of these hatch covers are constructed suitable hinged ‘hatch covers. A 10-inch composition hand pole is fitted in each of the hinged covers. Hinged oil tight. steel hatch covers are fitted over all sum- mer and fuel oil tanks. An anchor windlass is located on the forecastle head with an engine on the same bedplate. There are 10 steam winches of the National Hoisting En- gine Co.’s make, for operating cargo lifts. One steam capstan for warping the vessel is fitted aft on the poop deck with engine. The main machinery ¢onsists of a
