must convert the liquid into gas before it is burned. Gaso- 

 line lamps are either portable, with an individual generator, 

 or are connected to a system, with a common generator for the 

 entire system. Again, certain gasoline plants require a 

 special grade of light gasoline which is vaporized upon mixing 

 with air.

ous. They should be filled only by daylight, and care should 



be taken not to let the gasoline become exposed to the air 



either through a leak or by spilling. A gasoline lamp, unless 



of the vaporizing type, requires some time for starting, and 



must be heated before the gasoline can be generated. While 



it is burning, there is usually a hissing noise which is very 



disagreeable. Gasoline lamps are universally mantle lamps, 



and for this reason are very efficient. The most efficient 



lamps are those which furnish the liquid to the lamps under 



pressure. The gasoline lamp consumes the oxygen of the 



air and heats it much as the kerosene lamp.
