and 8th. They were all built in low spruce-trees, 

 about four feet from the ground, and were rather neat 

 structures, being made of hemlock twigs and lined 

 with a few feathers. They each contained four fresh 

 eggs. Several other nests were taken by Mr. Bailey 

 between the 8th and I5th" (Pr. Bost. Soc., xiv, 1872, 

 P- 363)- "A nest which I found in northern New 

 Hampshire was somewhat different, but contained three 

 eggs, which were white, marked with purplish and 

 brown, and average .68X-5O of an inch. Dr. Brewer 

 describes others as measuring about -75X55 of an 

 inch, and being white, or often bluish, ' blotched and 

 spotted with reddish-brown, purple, and darker shades 

 of brown.'" (Minot, B. N. E., 1877, p. 124.) 



Such is the usual and normal manner of the Yellow- 

 rump's presence in New England. There is some- 

 thing curiously erratic, however, in its breeding in- 

 stincts and capacities ; for it is known to rear its young, 

 in some instances, in localities far south of New Eng- 

 land, even in the West Indies. A notice has lately ap- 

 peared of its nesting in Maryland (Bull. Nutt. Club, v, 

 July, 1880, p. 182). It is supposed by Mr. Allen, with 

 good reason, to breed occasionally in Berkshire County, 

 Mass. ; and no one need be surprised to hear of a nest 

 found in any portion whatever of New England.

Chars. " With a close general resemblance to the last, but throat 

 yellow, not white ; eyelids white, but no white supraciliary line; 

 cheeks not definitely white ; wing-bars generally fused into one 

 large white patch, and tail-blotches larger ; otherwise like coro- 

 nata, of which it is the western representative." (Coues.)
