BREEDING NoTEes.—In the Kowak delta on the 14th and 15th 
of June I took a set of five and one of six slightly incubated eggs, 
respectively. The two nests were similarly placed in the tops of 
clumps of grass at the edge of a marsh about six inches above the 
water. The nest proper consisted of closely-matted broad dry grass 
blades and stems, while the lining was entirely of white ptarmigan 
feathers, though not one shows above the rim. The deeply cup- 
shaped cavity is thus pure white, though when the bird was sitting 
she entirely concealed it. The internal diameter of the nest is 2.00, 
depth, 1.90; external diameter, 4.80, depth, 2.60. The ground 
colour of the egg is very pale blue. The set of six is quite uni- 
formly and thickly spotted with liver-brown and vinaceous tints. 
One egg of the set of five is like them, but the others are wreathed 
at the large ends with confluent markings of the same colours, while 
the rest of the surface is very finely dotted and blurred with a pale 
brown tint; so as to nearly obscure the ground colour. The eleven 
eggs average .74xX .57. (Joseph Grinnell.) I have several sets of 
eggs from the Mackenzie delta; a nest and five eggs were found by 
Rev. C. E. Whittaker on June 18th, 1900 at Peel river; another 
nest with five eggs was found at the foothills of the Black moun- 
tains by Mr. Stringer on June 13th, 1899; another clutch of four 
eggs was found, west side of Mackenzie delta, by Mr. Stringer on 
June 8th, 1899; the nests are made of dried grass warmly lined with 
feathers and were built on mossy knolls on the ground. (W. Ravine.)
