wood on the north, isa natural water ‘‘runway’”’ where most of 
the large timber was up-rooted in the terrible wind and ice storm 
of April, some seven or eight years ago; in one of those up-turned 
roots, below which there is, in the early season, a deep pool of 
water, I have on several occasions, in past years, noticed a nest of 
a water-thrush, and expected this year to take a set of its eggs 
from a cavity in the same old root, but a delay of several days 
having occurred after the time when I intended to have visited it 
for that purpose, I found when I did so on the 28th May, that I 
was Zoo date, the nest was there, but a glance at the four eggs which 
it contained showed by their galvanized appearance that they 
were far advanced in incubation, and I did not remove or revisit 
them; the cavity in which this nest was placed was small, the bird 
had either found it ready for her purpose, or had partly enlarged 
it, and the nest itself was made of weed-stems, dry grass, animal 
hair, and “hair-moss.” Usually when the cavity is large, this 
species uses a quantity of dead leaves in the construction of her 
nest. (W. L. Kells.) This bird is commoner at Sharbot Lake 
than on the St. Lawrence. Here I have found a number of pairs 
breeding in 1903. One pair had a nest and young on a small 
island, June 12th, 1903. (Rev. C. J. Young.)

675a. Grinnell’s Water-Thrush. 
Seturus noveboracensis notabilis (RrpGw.) Rrpew. 1885. 
We saw our first water-thrush at Painted Stone Portage. It was 
close to the edge of the water and was running through the under- 
growth which fringed the foot of a cliff. On the afternoon of the 
same day, June 26th, we noted another at Robinson Portage, and 
on June 30th, a third at Oxford Lake. When we arrived at Oxford 
House we found the species rather common, and from there to 
York Factory, as we descended the rivers, its sprightly song was 
heard daily. A pair seen at a portage on Hill River, July 7th, 
were feeding young just from the nest. Three specimens were 
taken in the marshy woods about York Factory, where the species 
was common July 11th to 17th, and one was taken August 8th by 
Alfred E. Prebles on Churchill River about 15 miles above Fort
