THc: iWUlA RUBBER WORLD 



[October i, 1905. 





THOUSANDS OF PLANTS 



Are Still Operated by Mechanically Trans- 

 mitted Power to the Detriment of 

 Light and Ventilation. 



In nearly uU classes of work there is some 

 adviinlAge in the omission of all or nearly all 

 the belts and shaft hanpers which are eom- 

 monly used. In silk mills, paper mills, con- 

 ffctionery factories or laundries, for example, 

 it is of tlie greatest im])orUince that tlie goods 

 wliich arc being manufactured arc kcj)t per- 

 fectly clean, and so long as there are shaft 

 liangers or l)eiis overhead it is absolutely iin- 



fiosslbie to avoid a certain amount of dirt and 

 njurv to the goods. The almost perfect clean- 

 liness of an establishment where the electric 

 drive is carefully worked out is soniellung 

 which one needs to see In order to fully appre- 

 ciate it. Moreover, the absence of this dirt in 

 the air is bound to be more healtliful to the 

 emi)loyC*s, and the amount of light available, 

 and consequently the quality of the work 

 wherever belts are omitted, is very greatly In- 

 creased. — *• Klcctric Power in Factories^ A
