504 TllK I'UK SEALS Ol' THK I'KIISILOF ISLANDS. 



OCTOBER 9. 



Went this afternoon to \isit the I'eef. While watching tlie bulls and bacliekrs 

 ill the little cove across from Zoltoi, I saw the whole lot start up in great fright for 

 no other reason than that an extra heavy wave made a noise which awakened two or 

 three. Thcyjumi)ed up and the whole flock nearly stampeded. In a few minutes 

 they were again sleeping or engaged in playing with one another. 



The testes of the bulls show in exactly the same manner as in September. In 

 some they show distinctly, in others not at all, depending upon position. In nearly 

 all they show somewhat if the animal is lying in a jjosition of relaxation. When the 

 animals first lie down they do not show. In 4-year-olds the testes show more 

 uniforndy than in tlie older bulls. 



From the toj) of the cliffs I watched the seals swimming back and forth in the 

 water. There seems to be a constant interchange between Kitovi and the IJeef past 

 East Landing. 



One big bull was seen passing slowly along at the foot of the cliff. In the clear 

 water he was diving to the bottom and i)lainly searching along, just as pups do. As 

 a rule the bulls in the water seem only to be playing, or just taking a bath. This 

 fellow seemed to have a puii)ose. 



From the rock pile above the Reef it is interesting to see that notwithstanding all 

 the disturbance and confusion created by the count on this rookery a week ago it has 

 resumed the exact shape it had before the count was made. The seals must have a 

 very definite sense of locality. 



Three killers, apparently the same crowd, are passing along the Reef iu the 

 direction of Otter Island. This seems to be their regular beat. There is no special 

 commotion among the seals. The killers are evidently feeding, as the usual flock of 

 gulls are hovering and lighting in their wake. 



ARDIGUBN. 



The slide is about as usual. Only 3 cows and no pups are on the flat above the 

 mouth. One starving pup is visible. The pups here are very large, many almost 

 seem larger than the yearlings. It is evident that many of these pups are not to turn 

 gray at all. In all likelihood certain black pups develop directly into the brown 

 yearlings and that the gray pups become the silvery yearlings. 



OCTOBER 10. 



This morning at breakfast the new chief, Nickoli Grumof, reported that a killer 

 ha<l come in almost to the wharf at the Point Warehouse after puj^s. He came in on 

 a great roller, and came very near getting stranded. .Vt one time he was more than 

 half out of water. 



In about an hour the chief brought u]) the half-eaten carcass of a pup which had 

 been attacked by the killer. The hinder part of the puj) was entirely gone. The head 

 was severed, except for the wind pipe, which united it to the body. The skin was 

 stripped oft' from the body, but remained attached to the head. The vital organs were 

 gone. 



.Tudge Crowley and I, accompanied by Ai»(illon llordnkofsky and Kar]) Itutcrin, 

 went this morning to Lukanin to try to get some pups for the examination of their
