FUEL. 379 



"Water gas is found in many places to be an econom- 

 ical beating material. It costs only about twenty-five 

 cents per thousand feet, and at that price is less than 

 one-half as expensive as coal, and is regarded by many 

 as cheaper than natural gas at current prices. While it 

 may come into general use in cities, few florists are so 

 situated that they can obtain it except at a considerable 

 expense for the laying of mains, and it has not as yet 

 been thoroughly tested for greenhouse heating. Gaso- 

 line can be readily handled, and florists are now looking 

 to it as a valuable source of fuel. When a burner 

 adapted for its use has been invented, it may revolution- 

 ize our present heating plants.
