388 ORNITHOLOGY AND OOLOGY. 



years- ago, one of his sons found a Grouse's nest with fifteen eggs, 

 which he brought home, and immediately placed beneath a hen then 

 sitting, taking away her own. The nest of the Grouse was on the 

 ground, under a tussock of long grass, formed with very little art, 

 and few materials : the eggs were brownish-white, and about the 

 size of a pullet's.- In three or four days, the whole were hatched. 

 Instead of following the hen, they compelled her to run after them, 

 distracting her with the extent and diversity of their wanderings ; 

 and it was a day or two before they seemed to understand her 

 language, or consent to be guided by her. They were let out to 

 the fields, where they paid little regard to their nurse ; and, in a 

 few days, only three of them remained. These became extremely 

 tame and familiar, were most expert flycatchers ; but, soon after, 

 they also disappeared. 



The eggs of this species are generally ovoidal in form, 

 and are often pretty sharply tapered at their small ends. 

 They vary in color from a dirty-drab to a grayish-white, and 

 are covered more or less thickly with fine spots or dots of 

 brown : some specimens have none of these markings, while 

 others are abundantly spotted. A large number of speci- 

 mens in my collection average about 1.80 by 1.25 inch in 

 dimensions.
