Labor Re- 



The refuse destructor requires the employment of 

 about 100 workmen. They work in shifts of eight 

 hours each. The plant is operated contin- 

 uously except from 6 o'clock Sunday morning 

 to 6 A.M. on Monday. When the plant is closed down 

 the drafts are reduced as much as possible and an 

 effort is made to retain the heat. On Monday when 

 operations are resumed, a small amount of fuel is suffi- 

 cient to bring the temperature to the normal, raise steam, 

 and set the plant in customary operation.
