many of them breed, and likewise on various spruce- 
grown islands of New Brunswick and Nova Scotia. 
Though I have not visited their haunts at the 
nesting season, I nevertheless had the pleasure of a 
close inspection of a Raven’s nest on an uninhabited 
island of Penobscot Bay. About the middle of 
May, when the Herring Gulls were laying their 
first eggs on this island, a party of boys discovered a 
Ravens’ nest in a spruce tree, containing three well- 
grown young. These they carried hie with 
them, and were keeping them, when I arrived a 
month later, in a hen-house, as they had tried to 
escape to five woods. One day the boys took me 
foetie nest; The spruces’ on -the island are not 
large, and the nest, though two-thirds way up, was 
only about twenty feet from the ground. Climbing 
to it, I found it to resemble the Crows’ nests seen 
on the island, only it was much larger. It was 
built of large crooked sticks, some of them as thick 
as one’s thumb, hollowed deeply. The lining was 
of grass and sheep’s wool, of which latter there was 
an ample supply from the flock that had been 
femmed over and left to run at large:” The well- 
picked carcasses that lay here and there suggested 
the well-known carnivorous habits of the Raven. 
As for the Black Guillemots, on many a rocky 
islet there is a small colony of chew, of from two 
or three pairs up to thirty or more. To one such, 
near Matinicus, I have often been. It is a low- 
lying strip, a couple of hundred yards long and 
rather narrow, composed almost wholly of round 
stones and Boulders heaped together in wild confu- 
sion. Sometimes I have rowed there in a fog, by
