 should be hauled and spread on the land daily. It will generally become 

 too dry for flies to breed in. 



The most expensive and disastrous I'allacy in lliis u hole pn»bl«Mii 

 is the "fly-tight" pit or receptacle for stable wast<'. This has been ami 

 still is recommended under the plausil>le excuse, "Make them flv-tight, 

 so the flies cannot get in to lay their eggs." Eggs by tlic luillion an* 

 laid in the material he/ore it 

 is put into the pit ; the tight 

 construction, nuikes it an artifi- 

 cially perfected fly incubator, 

 and when it is opened, as it 

 must be dailv, the flies swarm 

 out. By this method w'e actu- 

 ally go to great labor and ex- 

 pense to breed more flies. 



In cities, instead of fly-tiglit 

 stable pits, we should have, 

 by city ordinance, readily ac- 

 cessible elevated hoppers or 

 concrete-floored bins, and the 

 city should arrange to empty 

 these clean to the concrete at 

 least once a week from May 

 to October. It would be much 

 better, for purity of air and
