young white ones, which they both did have. 

 Hen I. (1907-8) I hatched in my own aviary, 

 and she was almost white in the nest feathers and 

 always continued very pale, and when mated to a 

 goldfinch gave me pied mules. Hen II. (1909-10) 

 had peculiarly pinkish-yellowish chicks, so I 

 suspected her too of carrying white blood, and in 

 1910-11 mated her to a first hybrid generation buff 

 cock, from which mating I got only one pale hen. 

 The following year (1911-12) I mated both mother 

 and daughter to a white cock (1910-11, second 

 generation), and got white chicks from both 



of them. The daughter is the hen in Pair IV. in 

 Table 78. 



I have other pale hens (older) related to the white 

 sport (but not descended from her), as Miss Lee 

 and I have for many years exchanged birds from our 

 aviaries. These hens I intend this year to mate 

 with white cocks, to prove if they are hybrids or not, 

 as I fancy some of them carry white blood too. 

 (Miss Lee, I think, must have many birds capable of 

 producing white chicks — as her birds are mostly very 

 pale — but she does not I think care to experiment 

 systematically.)
