142 THE CORNING EGG FARM BOOK 



The method used in accustoming the birds in the 

 Colony Houses to get on without artificial heat is as 

 follows: for the first three or four nights, depend- 

 ing on the coolness of the weather, all canvas drops 

 are down, and a large, lighted, stable lantern is hung 

 in the House. For the next few nights after the 

 lantern is removed the drops are left closed. Then 

 one drop is propped out an inch or two, and from 

 night to night the opening is increased, until the drop 

 is left up altogether. After that, for a few nights, 

 one drop is left up and the other closed. Next, the 

 second drop is slowly worked up in the manner de- 

 scribed, until it reaches the height of the hook. 

 After this they are never lowered again so long as 

 the birds remain on the Range.
