MISCELLANEOUS FERTILIZERS 195 



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 ex- 

 crements, have a lower value than average stable 

 manure. They cannot be used economically when 

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

 a quick-acting manure is desired. For sanitary rea- 

 sons, the use of street sweepings is not always desir- 

 able, as mixed with the horse droppings frequently 

 there are associated accumulations of filth from dwell- 

 ings contaminated with disease producing germs. 

 Crude garbage has a low manurial value, but when 

 sorted and cremated, the burned residue can be used 

 to better advantage as a fertilizer than the raw gar- 

 bage, and is without the objectionable and unsanitary 

 features.
