392 NOTES ON THE 
little quantity of horsehairs. Some nests have fine grass in 
their lining. They lay four fiesh-tinted white eggs, spotted at 
the large end with brown, and dotted with pale-brown and lav- 
ender. 
Mr. Washburn obtained a beautiful specimen at St. Vincent, 
in the Red river valley late in August.

PINE WARBLER. 
This seems to be a rather uncommon species, first obtained 
by Mr. Geo. McMullen of Minneapolis, on May 10th, 1876, 
since-which time it has been collected by several different per- 
sons who have submitted them to me for examination. 
I have found that they arrive much earlier than the date

the 20th. 
They breed in the quiet pine forests, their nests being 
usually on small sized pines, and about twenty feet from the 
ground. It is not strange that they seem quite rare even 
though there may be a good many in the country, when their 
solitary habits in breeding exclude them so effectually from 
observation, The nests might escape the most vigorous 
scrutiny, so well is it and both of the birds concealed in the 
dense evergreen foliage. They consist of strips of bark prob-

large collection of nests, those of this species are character-
