which month they linger before final departure for 

 their southern winter resorts. During the migrations 

 they are generally dispersed in all kinds of woodland. 

 We have several excellent advices of the nesting of 

 this species in New Hampshire and Maine, from Mr. 

 Deane, Mr. Brewster, Mr. Maynard and others. A 

 particularly good account of the bird's habits is given 

 by Mr. Brewster (Bull. Nutt. Club, ii, 1877, pp. 1-7), 

 who found breeders on Mount Monadnock, N. H., and 

 states that the birds are everywhere common in sum-

 0.50 broad, dull white, minutely dotted all over with 

 brown, and wreathed about the larger end with brown 

 and clouded lilac spots and blotches. Several other 

 nests, described by Mr. Maynard, contained four eggs 

 apiece, and were all alike placed in small hemlock or 

 spruce trees, a few feet from the ground; their com- 

 position was quite similar, but sometimes fine black 

 rootlets replaced the horse-hair lining, or moss and
