232 SOILS AND FERTILIZERS 



278. Street Sweepings. - - The horse manure and de- 

 bris collected from paved streets in cities and known 

 as street sweepings have some value as fertilizer, and 

 are occasionally used for market gardening purposes. 

 Street sweepings, because of the loss of the liquid 

 excrements, have a lower value than average stable 

 manure and cannot be used economically when labor 

 and the cost of hauling are high-priced, or when a 

 quick-acting manure is desired. For sanitary reasons, 

 the use of street sweepings is not always desirable, as 

 mixed with the horse droppings frequently are associ- 

 ated accumulations of filth from dwellings contaminated 

 with disease germs. Crude garbage has a low manurial 

 value; when sorted and cremated, the burned residue 

 can be used to better advantage as fertilizer than the 

 raw garbage, and is without the objectionable and un- 

 sanitary features.
