Note 182 — Chapter VII
Daniel De Leon translation
A competitor with electricity, applied to lighting purposes, has recently arisen in the shape of the so-called acetylene gas, which was discovered in the United States, by means of an electrolytic process, similar to that used in the preparation of aluminum. A compound is made of calcium and carbon, called calcium-carbide, which, in touch with water, produces the acetylene gas. Its lighting power is fifteen times that of the ordinary illuminating gas, besides being much cheaper.
