This fan is always inmotion, drawing a column of air through each of the pipesand exhausting it through the large pipe leading up to theceiling. If a fire gets started in any part of the ship the fan will soon draw the smoke up through the particular pipe lead-ing to that compartment and as this outfit is located on thebridge of the ship, the officer in command has it constantlyunder his observation. .As soon as smoke is seen arisingfrom any pipe, the doors are opened and the air shut off and. 1-iRE Detector .d Extinguisher. the heavy steam hose which the sailor is holding is screweddown in connection with that particular pipe. This hose isconnected with the steam pipes from the engine room and ittakes only a few moments to fill any section of the ships holdwith live steam under heavy pressure. The steam acts as anexcellent fire extinguisher and does much less damage to thecargo than water. RUBBER IN CELLULOID MANUFACTURE. In making various celluloid articles, such as simple cane andumljrella handles that are only to be enlarged, a soft rubber coreis used. It is placed inside tlie celluloid tube, which is steepedin boiling water and the hot water expands the rubber core,thereby enlarging the tube. The rubber core is then withdrawnand the tube placed in the mold. An enlarged celluloid tubeopen at both ends is thus formed. Certain hollow objects arc made by introducing a rubber coreinto a hollow block. By heating and pressure, the celluloid ismolded on t
