614 GEOLOGICAL SURVEY OF CANADA. 
A rare summer resident in Manitoba. Only mentioned by a 
few observers. (Zhompson-Seton.) A rare summer resident at 
Avenue, Manitoba, arrived May 18th, 1903, and last seen August 
21st. (Norman Criddle.) A rare summer migrant at Indian Head, 
Assa. Only one individual seen in the spring of 1892, on June 
8th. Only one individual was seen at Medicine Hat, Assa., in 
the spring of 1894. (Spreadborough.) 1 found the nest of this 
species north of Waterloo, Ont., May 22nd, 1899; nest in a hemlock 
five feet from the ground. (W. Raine.) One was taken at Ox- 
ford House, Keewatin, July 3rd, 1901. (4. A. Prebles.) 
BREEDING Notes.—Here'the first nest that claimed my atten- 
tion was one placed on the side of a small birch tree where a tuft 
of twigs grew out from the ground. I soon reached and secured 
this; it contained three fresh eggs; these were of a white hue with 
dottings and patches of a brownish or flesh colour, the nest itself 
being composed of fragments of bark, rootlets and hair; I did not 
then note the owner, nor could I at that time have identified the 
species, but I gave thema name and placed them in my collection. 
Two years after—June, 1879—I was out in a piece of swampy 
woods south of the town, when my attention was arrested by the 
actions of a small bird which was constructing a nest among some 
leafy twigs growing on the small horizontal branch of a little 
water-elm, about three feet out from the trunk and ten feet off 
the ground. Some days after I viewed this nest again, it then 
contained one egg, and three days more when I revisited it, I 
found the bird at home sitting on three eggs, which I inferred 
were the full set, and that incubation had begun. When this bird 
flew off her nest and took a position on a branch near-by, uttering 
a few chip-like notes, I identified her as a female bay-breasted 
warbler. The nest and eggs were exactly like those above de- 
scribed, and of course both belonged to the same species. Some 
days after thisI found another nest of this bird in a neighbouring 
lowland wood; this was placed in the top of a small hemlock 
about fourteen feet from the ground, constructed of similar 
materials, and contained four eggs. Since then no nest of this 
species with eggs has come under my observation, but I have 
noted a few others in which young had apparently been raised. 
. One of these was on the side of a small cedar where a little 
branch grew out, and about four feet off the ground; another, 
evidently a new nest, but after the breeding season when I found
