This rather remarkable bird was used as a breeder for three 

 successive years, and then retired merely because no more of 

 his progeny were needed, and not for any evident diminution 

 of vigor on his part. This bird was first bred as a cockerel in the 

 spring of 1908 (hatched in 1907). All that was known of his 

 ancestry was that he was the son of a hen that had laid 200 or 

 more eggs in her pullet year. Some notion of the vigor of $ 

 D31 as a breeder may be gained from the fact that, taking all 

 three seasons together and including all parts of the breeding 

 season in each year, 89.4 per cent of all the eggs laid by hens 

 mated with him were fertile. This is an extraordinarily high 

 record considering all the circumstances, and particularly the 

 seasonal and housing conditions. So far as concerns adult 

 daughters the breeding history of this bird is as follows :
