Electricity appeared as a eolation Jot the smoke problem in a recent demonstration. The siaoko-abating appliance r» moved the soot from 900 cubic fedt of snioko .1 minute at a total cost of about a penny a day for operation. Tho action of the apparatus consists in precipitating tlie solid particles ill tho smolte by means of' a powerful fiieetrio current, and its invention is based on the feetthat one-third to one-half of the -solid matter in smoke from smelting furaaess consist# of particles of iron oside. Electrical current is applied to the smoke by means of a wire woven through a number of small pipes placed at the top of the chimney-so that the smoko must pass through them. As soon'as the electricity is turned on tho small particles floating in the smoko are changed to large particles which full l.snck into a bin by their own. weight. Its application is not confined, however, to smelting furnaces, for it has been found that tho device works as successfully on any kind of smoke, cement, 'or ere dust, * Soft coal and ashes were used in the demonstration. A French firm' is. offering to the own.Tors of woods cast-iron cylinder* to put round nil their young trees to prote-ct them against: hungry cattle.
