During the past six years Mr. Waters has! been superintendent of the Ver- don yards. David H. Gildersleeve, vice presi- dent of the company, 'thas had con- siderable experience in the pump- ing, hydraulic and gas engineering field. During the Spanish-American war, and for some time after its close, he superintended the construction of the new sewerage system of the city 2. ¢ & dent and THE Marine REVIEW of Havana as a first lieutenant in the United States corps of engineers. For the past five years he has 'been connected with the C. W. Hunt Co; makers of coal carrying machinery. Frederick L.

' German Naval Dockship -- Vulkan. SHIP of great in- ship Vuikan, which has recently been placed in commis- sion in the German navy. It has-been built in accordance he Imperial naval 'constructor, Ph.von ee Kittzine, of: Kiel, Coons ; by the Howaldts- i werke atthat place. The distinguisHing feature of the Vul- kan is its peculiar form. The vessel it- self consists primarily of two hulls, both resembling ships linked together fore and aft above the water line by steel girders made up of angles and _ plates. This linking or joining rogether is done in such a manner that a torpedo boat or submarine riding at the surface can steam between the two hulls. When the small craft is in this 'position tackles erest is the dock- with the plans of April, 1909 and crane hooks can be lowered from the dockship, and the little vessel can Be lifted out of the water and docked, After that, from both of the inner sides of the dockship, beams are swung under the smaller vessel, so as to form a platform on which she may rest, The beams are fastened by hinges to the ip- ner side of the dockship. That is to say, they are fastened to the inner side of one of one of the other hulls, and are pulled up against the inner side of the other hull as far as is advisable to raise the docked boat. These beams play no actual part in the raising of a vessel, that action being performed . wholly by the cranes and tackles on the dockship, The center of the dockship is free, and the submarine or torpedo boat may be raised as far out of the water as de- GERMAN NaAvaL DockKsHIP VULKAN.

The hoisting or lifting apparatus is arranged on two double portals or bridges built up of lattice girders, the bases of which girders rest on the decks of the two hulls. These girders also serve as a rigid connection between the two hulls. The means of propulsion of the ves- sel are interesting, neither recip- rocating engines nor turbines but elec- tric motors for driving the two propeller Current 1s delivered to the two. in- dependent turbine sets. if the vessel is to steam slowly one gen- erator set only is run.
