DISPOSAL OP REFLH. 



usually by means of brooms. It consists not only of 

 refuse which has original <<! from vehicular and other 

 travel, but contains sweepings from the floors of houses, 

 ashes, refuse, and other wastes. Street sweepings arc .i 

 little use except to fill up low land. In some cases street 

 sweepings have been washed in tanks and the sand and 

 gravel recovered, but this is usually an unprofitable 

 undertaking. 



Dead animals are collected and used by private cor- 

 porations for the recovery of the hides, hoofs, bones, 

 grease, and other saleable parts. They are taken from 

 the streets at public expense, usually by special con- 

 tract.
