and two sisters, H 2802 and H 3246, granddaughters of F 433 but not inbred 

 though related to male G 1965. 



Inbred pen 3 included eight females mated to male H 317. This male was 

 outbred but traced to hen C 1124, as his only paternal greatgranddam. The 

 females used were three sisters, H 1565, H 3063 and H 3064, which traced to 

 C 1124 in the third generation on both sides of their pedigree; pullets H 2791 

 and H 2792, full sisters which trace to C 1124 in the fourth generation; sisters 

 H 1854 and H 1856, carrying the same relationship to C 1124 as the two pullets 

 just mentioned and differing only in that their dam was a full sister to the dam 

 of the two pullets in question; pullet H 2151 from a full brother-sister mating, 

 but unrelated to male H 317.

The check pen females used as breeders in 1928 were all early maturing but 

 one. They all showed satisfactory weight but there was a wide variation in 

 weight. Five of these birds lacked winter pause to three showing winter pause. 

 There was but one of the eight high for intensity. Two of the group were broody 

 as pullets, and one had an incomplete record. In persistency all were genetically 

 high as shown by the ability to lay for not less than 315 days before going into 

 complete molt. Their annual egg records were moderately high and fairlv uni-
