This cargo must be placed in the vessel so that she will float on a level keel and draw 20 ft. of water. Fig. 52 shows the cargo 1,888 tons placed aft 127.46 ft. from the center of grav- ity and equal to 204,040 ft. 'tons. Forward 1,412 tons is placed 170 it. before the center of gravity, giving the same 204,040 ft. tons which is neces- sary to float the vessel on an even keel. In this arrangement the cargo © is placed as far forward and aft as pos- sible compensating for the excessive buoyancy beyond the cargo spare. There is an excessive weight at this point (170 ft. forward and 127.46 aft.) but it will be less harmful to the structure than if it were placed in the middle. The fuel used between the loading point and home port is not considered in this calculation. When the vessel is loaded it will draw more water aft, owing to the fuel 'being aboard, but be on a level keel when at destination if so desired. NEW STEAMER E. G. CROSBY. The steamer Naomi, which burned on Lake Michigan last year, is being completely rebuilt by the Manitowoc Dry Dock Co. Manitowoc, Wis., for the Crosby Transportation Co., of Milwaukee. The Naomi, which was built in 1881 by the Detroit Dry Dock Co. at. Wyandotte, Mich., and was called the Wisconsin, was one of two May, 1909 iron sister ships built for the Detroit, Grand Haven & Milwaukee Railroad. The second of the pair, the Michigan, was lost after a very short Service, but the Wisconsin has continued jn commission all the year round, although the name was changed to Naomi in 1895. The hull was not damaged in the fire which destroyed most of the ~--hgple-b Oak 2h RIO)" « WAT Lack Bia 4 Punched Kn I Ir ag sy f | : PPO WH. a NI 5 A - BiB*72" | fender 1-4 CUM OY Hl eS : 6xl0 Daal" (FY pees Main ech -- ON <i Y .

Crosby, as she will be known, will be a better ship than ever. Fig. 1 shows the ship as she will appear with her new upper works. Fig. 2 shows an interesting detail of construction. In order to obtain more deck space a 2-ft., 6-in. guard has been worked and the brackets plated, which, with the heavy channel carrying the fender wales contribute great addi- tional strength. The steel construction has. been car- ried up to and includes the cabin deck and the unusual height between decks is noticeable. - There are three decks, viz., main, cabin and-upper deck. On the cabin deck there will be 54 staterooms and parlors, a number of which will be connecting. The upper deck will con- sist of 46 staterooms, in addition to pilot house, texas and captain's room. The passenger cabins and social halls will be finished in curly birch and, will
