very heating, and as soon as the chick's blood is 

 over-heated its digestive organs fail to work properly, 

 and what is now known as " White Diarrhoea " almost 

 invariably develops. It is claimed by some authori- 

 ties that this difficulty comes from a germ which is in 

 the egg before incubation. This may be the case, 

 but it is certainly true that wrong feeding will bring 

 this germ into active life, and snuff out the existence 

 of the chick. 



Another phase, which has been a special study on 

 The Corning Egg Farm in the brooding of chicks, is 

 an abundant supply of fresh air, not only in the room 

 itself, but also to have the oxygen fed to the chicks 

 properly when they are under the hovers. The use 

 of gas for heating the hovers was found a decided 

 improvement over the lamp, so far as the freshness 

 of the air went, but, for procuring the purest hot air, 

 to flow up into the hovers, we are now installing a 

 system of hot water pipes. 



In a dwelling house, properly constructed, the en- 

 tire heating apparatus is a hot air furnace, with a cold 

 air box connected with outdoors constantly bringing in 

 a fresh supply of pure air to be heated. If it were pos- 

 sible this would be the ideal way of supplying the 

 heat to the hover, but of course in a long Brooder 

 House it is impossible to do this. The nearest ap- 

 proach to this system of heating is a trunk line of hot 

 water pipes, extending beneath the hover floor, with 

 the pipes enclosed in a long box, standing some two
