ZOOLOGY. 249 



winter of 1853-54, I noticed immense flocks of swans, apparently of this species, collected 

 along the shores of the river mentioned, and spread ont along the margin of the water for a 

 distance varying from an eighth to a quarter of a mile. 



I obtained a fine trumpeter swan on Pike lake, Minnesota, in June, 1853. They are quite 

 common on the lakes in that vicinity in summer, breeding and raising their young. — S. 



The trumpeter swan associates with the preceding species at the same season and in the 

 same places. Both arrive from the north in the beginning of December, but I have not had 

 an opportunity of noticing their departure. Swans are said to be rare visitors near San 

 Francisco. — C.

 Anas hyjerboreu, Gm. I, .''114 — Wils. Am. Orn. VIII, 1814,76; pi. Ixviii and Ixix. 

 Sp. Ch. — Adult : Bill and legs red. Color pure wbite. Primary quills black towards the end, silvery bluish gray towards the 

 base, where the shafts are whi^e. The spurious quills are aleo bluish. Inside of wings, except primary quills, white. Immature 

 birda have the head washed with rusty. 



Snow geese were seen by me moderately abundant on the shores of Clark's Fork of the 

 Columbia and its branches during my canoe voj'age from the St. Mary's valley (Rocky 

 mountains) to Fort Vancouver in 1853. They were much more tame than the brant or other 

 geese I have seen; so much so that myself and party had several shots at a small flock, which 

 we approached so near that I killed a fine individual with my revolver. 



I obtained a very good specimen at Fort Steilacoom in December, 1856, where it is not 

 uncommon during the cold months. — S. 



The snow goose occasionally stops on the sand bars and prairies along the coast, but the 

 greater jjai't of them seem to go on directlj' to the plains of California, where they abound in 

 winter. 



Geese were seen in August by some of our party on the summit of the Cascade mountains, 

 where they probably breed, in company with ducks, shell-drakes, and cranes. I did not find 

 out which were the species observed. — C.
