 chick is to result, must be maintained. So far as 

 moisture goes, it is not a question of moisture at the 

 time of hatching. If the proper amount of moisture 

 has been always present during the period of incuba- 

 tion there will be no difficulty at the time of exclusion. 



Where a large amount of incubation is going on,

 possible, nay, even probable, that any of the mam-

 be desired, still, they do solve the difficulty of a great 

 number of individual fires sucking the vital oxygen. 



Of the mammoth machines now on the market there 

 are two which produce better chicks than any of the 

 others, so far as we can see. There are features in

 our point of view, made it more desirable than the
