concerns fecundity, but in all probability no particular effort 

 towards breeding for high egg productiveness had ever been 

 made in the stock , from which he came. He was bred as a 

 cockerel in the season of 1908 with the results set forth below.

In this case, while the number of successful matings was 

 small, the families were relatively large. In the case of ? 366, 

 set down here as probably of class 6, it should be said that this, 

 conclusion as to her gametic constitution is reached from a study 

 of her daughters' and granddaughters' behavior. Her own win- 

 ter egg record was 33, which on this view is regarded as a 

 somatic fluctuation from the Lt (Under 30) class.

As in the case of c? 65 nothing is known regarding the 

 breeding of this bird, it having been purchased from Mr. Geo. 

 W. Hillson, of Amenia. N. Y., early in 1908. It was bred as a 

 cockerel the same season. The only matings to get adult daugh- 

 ters were those with class i females. The breeding history is 

 as follows :
