1. The Imperial Gas Machine
THE IMPERIAL GAS MACHINE is an Automatic Gas-Making Apparatus, designed for supplying Residences, Hotels, Factories, Mills, Churches, Colleges, Public Buildings, or groups of buildings, with a safe and cheap illuminating Gas. The machine is simple, durable and reliable, being made of heavy, non-corrosive metals, well put together, and requiring no more care or attention than is necessary in filling, cleaning and trimming one kerosene lamp.
The Gas IS made by impregnating common air with the vapor of Gasolene. It is then conducted through iron pipes and ornamental fixtures, the same as ordinary street gas, and in burning through either the open or Argand burners, it gives a clear, bright light, fully equal to the best coal gas.
The cost of the Gas varies, according to the price of Gasolene, from seventy-five cents to one dollar per 1,000 cubic feet.
NO ARTIFICIAL HEAT is used in making the gas, and buildings lighted with it are insured by all the American and British Insurance Companies at the same rates as would be charged if coal gas were used.

The material from which the Gas is made is known commercially as Gasolene. it is one of the lighter products of petroleum, and can be obtained in large or small quantities from oil refiners or dealers in all our large cities. The price of Gasolene fqr many years has not exceeded fifteen cents per gallon.
