The processthey use they guard very carefully, and noone is allowed to know anything about it. The discovery of this metal for making fila-ments is a great advantage to the light con-sumer, as the consumer can obtain two orthree times the quantity of light at about one-half the consumption of electricity. It is es-timated in some instances that an increase ofone thousand per cent in value to the con-sumer is obtained by the use of tungsten lamps,as, in 1885, with the old carbon lamp witha rate of 25 cents per kilowatt hour, youcould obtain 800 cand
