Here again the agreement between observation and expecta- 

 tion is very close, quite as close as could be expected with the 

 numbers involved. The mean production of the 4 birds in the 

 'Over 30' class in the A matings is low.

This bird was one of the original males with which the pres- 

 ent breeding experiments were started in 1908. The only thing 

 known about his ancestry is that he was the son of a hen laying 

 200 or more eggs in the year. He got only a small adult female 

 progeny, and was used as a breeder only one year. His breeding 

 record follows.
