may destroy the whole brood in the nest of the species in which 

 it is cradJed; on one occasion I found a nest 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 

 a very 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 bpth cases these were evidently advanced 

 in incubation, and were not molested ; I concluded that in this 

 tract of forest about a dozen pairs of this species were breeding, 

 but they have many enemies among other birds and small 

 animals. {W. L. Kelts?)
