the lamp-closet must have four holes for ventilation, otherwise the lamp will not 

 burn. The lamp-closet is the space within the incubator under the tank. Turn 

 the eggs carefully every morning and evening, and after turning sprinkle them 

 with quite warm water. Two thermometers should be kept in the incubator, 

 one half-way between the centre and each end ; the average heat should be one 

 hundred and five degrees. If ihe eggs do not warm up well, lay a piece of coarse 

 carpet over them. If they are too warm, take out the lamp and open the cover

for a few minutes, but do not let the eggs get chilled. If they should happen to 

 get down to ninety-eight or up to one hundred and eight degrees, you need not 

 think the eggs are spoiled. They will stand such a variation once in a while ; 

 but, of course, a uniform J;emperature of one hundred and five degrees will 

 secure more chickens, and they will be stronger and more lively. In just such 

 an incubator as this one I have described, I hatched over two hundred chickens 

 two years ago. 



For those who are ambitious to try top-heat, the same sort of a tank is re- 

 quired, but a boiler must be attached at the side with an upper and lower pipe

for circulation. Any plumber can attach the boiler, and the faucet must be at 

 the bottom of the boiler on one side. The drawers containing the eggs should 

 slide beneath this tank. A stand for the lamp should be screwed to one end of 

 the case m such a position as to bring the lamp under the boiler. (See picture ) 

 This incubator can be cooled by raising the lid, turning down the lamp and pull- 

 ing the drawers part way out. In both incubators while the eggs are hatchine 

 sprinkle them two or three times with quite warm water."
