may destroy the whole brood in the nest of the species in which 
it is cradled; on one occasion I found anest of the chestnut-sided 
warbler which contained four cow-bird’s eggs, and but one of the 
warbler’s own; the eggs of this species are of a whitish hue, with 
avery irregular wreath, or belt, of a brownish colour, around the 
larger end, and some dottings, sometimes of a blackish hue, on 
the middle surface; the smaller end is unmarked; the other nest 
of this species, noted on the same date, was near the edge of the 
wood, and placed between several stalks of raspberry vines about 
two feet off the ground, and composed of materials much similar 
to the other, with the exception of the horse-hair lining, and was 
not so bulky in size—this on the 30th of May, contained four 
eggs; a week after, two other nests of this species were noted, 
both deeper in the wood, and both placed in the forks of little 
maples, but at varying elevations from the ground, one being 
about four feet, this contained four eggs, the other which con- 
tained three eggs, was about two feet off the ground, and by the 
side of a pathway. In both cases these were evidently advanced 
in incubation, and were not molested ; I concluded that in this 
tract ot forest about a dozen pairs of this species were breeding, 
but they have many enemies among other birds and small 
animals. (W. L. Kells.)
