 ing and the fire started. With the addition of a small 

 quantity of wood, the entire mass can be burned out in two 



hours, after which the 

 incinerator is ready for 

 refilling. 



Into this crematory 

 should be thrown all 

 waste papers, worthless 

 pieces of wood, old cloth- 

 ing, bones, poultry 

 feathers, bodies of poultry 

 and small animals, and 

 any other worthless 

 refuse that will burn. 

 Only a small quantity 

 of fuel is required to be 

 mixed with this material 

 to cause it to burn. 

 While the receptacle is 

 being filled with refuse, 

 the draft opening and 

 the top should be pro- 

 tected by a light covering 

 of sheet iron or wood. 



It is advisable that all 

 tin cans and bottles as 

 soon as emptied be thrown 

 into the incinerator. 

 Cans, when first emptied 

 of their contents, usually 

 have adhering to their 

 walls a large quantity of juice or other material that will attract 

 flies. After a rain the cans will be partially filled with water 

 and afford an excellent breeding place for mosquitoes. Later 

 on, the paper wrappers on the outside decay and become

Fig. 302. Plan and section of an 

 incinerator, constructed of hard-burned 

 brick laid up in cement mortar. It was 

 erected within 50 feet of the kitchen door, 

 and burned all solid refuse from a kitchen 

 where 250 men were boarded, the only fuel 

 used being the paper and packing boxes 

 that came with supplies.
