No. 582] EGG-LAYING ACTIVITY IN DOMESTIC FOWL 367 



both legs and beak, 31 had ear-lobe records of 20 per rent, 

 or less yellow on October 28. These averaged a yoarlv 

 total of 191.9 eggs. The 40 birds of those in Table III 

 that on this date had 20 per cent, or less yellow in ear- 

 lobes, irrespective of the color of other parts, averaged a 

 yearly total of 189.4 eggs. It appears therefore that hens 

 with a higher yearly average may be obtained by selecting 

 those that are pale in all parts — ear-lobes and beak as we 1 

 as in legs — than if only one of these parts is considered.
