We reared all our chickens with this apparatus the whole 

 of one season, with no failure or difficulty ; and several 

 breeders of our acquaintance were fully as successful. But 

 during a second season, when pressure of work made it 

 necessary to turn over all management to a servant, there

was considerable mortality, and very few chickens really did 

 well. This experience also we found to be extensively shared 

 by others. We gradually traced most of these comparative 

 failures chiefly to two causes, the first being sheer neglect to 

 attend to the necessary daily deodorisation of the apparatus, 

 and the second too high a temperature. When care was taken 

 as regards these points the earlier success was repeated. 



It is, however, very difficult to prevent the Cheshire form 

 of apparatus from becoming too hot for health, and the close 

 sides confine the air to an extent only controllable by constant 

 watchfulness. Of late, therefore, it has been practically 

 superseded, either by apparatus worked on the " Hydro " 

 plan, already described in its application to incubators, or by
