Additions to the Geological Survey's Collection of Eggs, in 



June, 1902. 



The following" sets of eggs of Canadian birds have been 

 received from Mr. R. W. Tufts, of Wolfville, Nova Scotia, who 

 collected the whole of them and who has kindly furnished the in- 

 formation in regard to them. 



" Golden-crowned Kinglet [Regxlus satrapa). 



" Set I, of nine eggs, collected at Wolfville, May 12, 1902. 

 Bird seen, incubation fresh. Nest hanging from thick spruce 

 limb, near the end, about fifteen feet trom the ground, composed 

 of green moss outwardly woven with "beard moss" {Usnea) and 

 lichens, and lined with long hair and feathers. Entrance at top. 



"Set II, also of nine eggs, collected at Greenwich, King's 

 Co., N.S., May 13, 1902. Bird seen, incubation fresh. Nest in 

 spruce tree, hanging from end of limb about fifteen feet up, com- 

 posed outwardly of green moss and beard moss, lined with hair 

 and robins' feathers. It was found about half completed April 2, 

 and the eggs were taken May 13. This shows how long it takes 

 these little birds to build their nests. 



" Red-breasted Nuthatch (Slifn Canadensis). 



" One set, of seven eggs, collected at Wolfville, May 8,1902. 

 The bird was seen, and the incubation one-fourth advanced. Nest

 cayed wood, mixed with grass and a few feathers. Entrance

 Co., April 29, 1902. Birds seen, incubation fresh. Nest in a 

 small spruce tree about six feet from the ground, composed ot 

 twigs and lined with fine dead grass and rootlets. No mud
