the ravens live in large numbers about the village, perching on the 
roofs of the houses, and hopping about among domestic fowls as famil¬ 
iarly as the chickens themselves. These ravens spend much of their 
time on the wing, circling high over the town and bay, and perform¬ 
ing a series of extraordinary evolutions. They sometimes drop a 
long distance in a series of heels-over-head revolutions like an acro¬ 
bat, ending in a long glide on outspread wings or in some other ec¬ 
centric performance, always accompanied by explosive cork-drawing 
sounds and a variety of other cries and croakings. They appear to 
enjoy especially making these playful flights during hard gales, when 
the entire raven-colony will take part. They soar, turn, and twist, on 
facile wing, and fill the air with a medley of strange cries, as if taking 
impish joy in the fierce wind roaring across the rugged mountain¬ 
sides and beating the surface of the bay into a froth of flying spray. 
Although seeming so jocular in mood, these black-garbed birds are 
remorseless pirates, robbing other birds of their eggs and young 
whenever opportunity offers.

From a Photograph by A. C. Bent 
The morning was clear and absolutely calm, the only breaks in the 
glassy surface of the swelling sea those made by the wake of the 
steamer, and the ripples circling from the breasts of thousands of 
water-fowl—murres, anklets, gulls, and fulmars—and a few fur-seals. 
The swarming abundance of bird-life about the rocky shores of 
the Aleutian chain, and of the islands of Bering Sea, adds wonderfully 
to the interest of these frowning coasts. The cliff-walled shores of the 
Fur-Seal group, and of the islets in Bering Strait, which stand like
