✦ Synopsis

Electric Light in Farming.--M. Albaret has" invented an apparatus for the application of electric light to agricultural labors. A portable engine, of 4 or 5 horse-power, carries a mast, '2.0 or 25 metl:es (65'6 or 82 ft.) high, and drives a Gramme machine. The electricity is conducted to the regulator of the light, in a lantern at the top of the mast. The mast, which is composed of numerous iron tubes, is raised or lowered at pleasure by a winch at its base. The lantern is connected with.pulleys, so that it can be brought down without lowering the mast.--Les Mondes.
