As is well known, many of these come from the Continent, and the shortage caused by the war may mean considerable inconvenience in the lighting industry. Hut the supply of carbons forsearchlights is at the present moment an even more vital matter. When our safety is dependent on the efficiency of our fleet a shortage here would be highly inconvenient, and the existence of a factory and raw material in this country has doubtless been helpful in enabling the Admiralty to make full provision in tin- respect. It is therefore only just to recognise the enterprise and foresight of the management of the General Electric Company in establishing, despite considerable initial difficulties, the carbon works at Witton.

Portable illuminants have a special value in the field—for Red Cross work especially, where powerful self-contained illuminants capable of giving a strong illumination but readily movable from place to place are required. We understand that several of the prominent acetylene firms have been supplying flare lights and other appliances for use on land and on board ship and quite a number of the portable tent-lighting outfits of the type made by the Thorn and Hoddle Acetylene Co. have been taken by officers to the front. For field hospital lighting apparatus of this kind should be most useful. Another form of illuminant which deserves to be even more widely known in this connection is the Blanchard incandescent oil system.
