 tundra where the young are raised. {Preble.) Very common in 

 the waters of Roes Welcome, especially on the east side along 

 Southampton island. Seen in the bays of Bafifin island. Breeds 

 abundantly on Southampton ; nests built on islands or along the 

 swampy edges of ponds not far from the coast. Feeds in the sea.

 east {Kumelin) along the whole Arctic coast {Richardson), and 

 very abundantly along the shore of Bering sea and in the 

 interior of Alaska as far as Fort Yukon. {Nelson.) A few have 

 been taken at Burrard inlet, B. C, ; also at Dease lake, Cassiar,

Breeding Notes. — In spring the black-throated loons arrive 

 rather late, coming to the vicinity of the Yukon mouth from, the 

 15th to 25th May. They appear singly, and are soon after found 

 scattered in pairs among the numberless ponds in the marshes 

 along the coast. The eggs are usually placed upon some small 

 islet in a secluded pond. There is no attempt at a nest, and 

 frequently the eggs lie in a spot washed by water when the \^ind 

 blows from the right quarter. In spite of this, however, tHe 

 young are duly hatched, and by the first of July may be found 

 swimming about with their parents. The eggs are dark olive,
