of cost of fuel. This is not true when one considers the cost 

 of operation, however. Again, a consideration of the poor 

 quality of the light produced by this lamp, its effect on the 

 eyes, its danger, and the fact that no workman can do his best 

 work under poor lighting conditions, makes this pioneer 

 means of home-lighting an expensive one. 



The kerosene tubular lamp is an improvement over the 

 flat-wick type in the amount of illumination, especially when 

 it is provided with a mantle which improves the quality and 

 increases the amount of light produced. 



310. A More Modern Lighting Plant. The farmer 

 who would install a truly modern lighting system in his home 

 has four kinds of plants from which to make his selection, 

 namely, the electric, acetylene, gasoline gas and Blau gas 

 plants. 



311. Electric Lighting Plants. (Fig. 339.) There are 

 definite advantages that the electric light has over other forms 

 of lighting that are recognized by every one. It is clean, saf e> 

 its cost is not prohibitive, and it does not make the air impure. 



Where the power for electric lights can be secured at a rea- 

 sonable price from power-distribution lines passing the farm, 

 the situation is ideal. Many farmers do not care to be bur- 

 dened with the chore of looking after a lighting plant. 



Until recent years, there were few unit plants on the mar- 

 ket; that is, an engine and generator built together. Most 

 of the generators were formerly belt-driven by a small engine 

 that could be easily used for some other purpose. There is 

 a number of unit plants on the market that are arranged 

 with a belt pulley for power purposes. Some farmers use a 

 power windmill to drive the generator.
