No. 559] BARRED PLUMAGE PATTERN 419 



Fig. 1. White Leghorn 



wholly barred or more often partly barred feathers. 

 These usually occurred either among the wing coverts or 

 the tail coverts, although they were occasionally seen in 

 the primary and secondary wing feathers or on the neck. 

 The barring on these feathers was always most distinct 

 at the distal end of the feather, but was never of so good 

 a quality as seen in the Barred Plymouth Kock breed. 

 The " under color" was usually dark. For these F 1 re- 

 sults two series of matings were made and 110 chicks 

 reared. In each series a different White Leghorn $ was 

 used, but the results were the same in both cases. 



Experimental Results ix F 2 

 Of the Fj fowls raised in 1910 one cockerel and five 

 pullets were bred together in 1911. The cockerel was 

 hatched as a pure white bird with no trace of black down 

 feathering. When adult, a single feather showing a buff- 

 yellow bar appeared among the coverts of each wing. 

 Among the saddle feathers were a few showing some huff.
