were conducted under the supervision of the manager of the Cornell 

 poultry farm and in accordance with the usual practice on that farm. 

 The general plan was to save all the chicks until maturity and then 

 save as many typical specimens from each group as could be satis- 

 factorily housed. Usually about 120 females and 30 males were kept 

 for the study of the three characters, size, shape, and color. When the 

 surplus stock was culled each fall, an effort was made to save the birds

representing the extremes of the types. If there were birds that .had 

 produced no chicks during the previous breeding season, these birds were 

 ■usually culled. In cases in which- nearly all the members of a certain 

 family had developed only a medium quality for the character studied, 

 the whole family was often culled to make room for more promising birds. 

 A large proportion of cockerels and pullets were usually saved for 

 the first year, and these were culled fairly closely before being used as 

 breeders during the succeeding years.
