THE BLACK-HEABED GULL. 161 



The Laplanders, according to Regnard, cover their heacta 

 with a cap made of the skin of a Loom (Loon), which word 

 signifies in their language, lame, because the bird cannot 

 walk well. They place it on their head in such a manner 

 that the bird's head faJls over their brow, and its wings 

 cover their ears. 



"Northern Divers," says Heame, "though common in 

 Hudson's Bay, are by no means plentiful; they are seldom 

 found near the coast, but more frequently in fresh-water 

 lakes, and usually in pairs. They build their nests at the 

 edge of small islands, or the margins of lakes or ponds 

 they lay only two eggs; and it is very common to find only 

 one pair and their young in one sheet of water—a great 

 proof of their aversion to society. They are known in 

 Hudson's Bay by the name of Loons." 



The Great Northern Diver measures two feet ten inohei 

 from the tip of the bill to the end of the tail, and four feet 

 six inches in breadth.
