inclosed incinerator can be built for this purpose. If burned in an open 

 fire, the papers tend to blow about the grounds. Under suitable conditions 

 rubbish and garbage can be satisfactorily disposed of by dumping in selected 

 locations. An isolated ravine or hillside may be used for a dumping ground 

 and the material allowed to rot. If feasible, the garbage and rubbish on 

 the dump should be covered with earth. 



Disposal of manure. While the horse and mule are rapidly being driven 

 out of service in park systems, there are still some systems that make use 



of the older method of motive 

 power. Horses may be kept 

 at camps in outlying reserva- 

 tions also. Wherever horses or 

 other live stock are kept in 

 park areas the manure must 

 be disposed of in a manner 

 which will prevent fly breed- 

 ing. The manure may be used 

 for fertilizer about the park 

 areas, or given or sold to near- 

 by farmers. Small quantities 

 of manure may be burned in a 

 garbage or feces incinerator, 

 or placed in windrows and 

 burned. Crude oil may be 

 used to assist in burning the 

 manure. In warm, dry 

 weather manure may be 

 spread in a thin layer on the 

 bare earth where it will be 



quickly dried by the sun. Flies will not breed in dry manure. Manure 

 when well mixed with straw may be composted by dumping in a pile about 

 three feet high and five feet wide at the base. The manure is firmly packed 

 and covered with six inches of tamped earth. The edges of the pile and 

 the ground around the edges to the width of one foot should be sprayed by 

 a solution of borax (4 ounces to one gallon), using about a quart for every 

 square foot. If borax is not available the ground upon which the manure 

 is to be piled, and the margin of one foot beyond the edges of the pile, 

 should be soaked with crude oil. The composted manure ferments and pro- 

 duces enough heat to kill all the fly larvae, while the covering of earth pre- 

 vents the deposit of eggs by flies. The borax or the oil will kill the few larvae 

 that escape from the edges of the stack.
