SIVUTCH ROCK AND ARDIGUEN. 321 



and flat, the lauding is easy. Here the seals come and go all the time, and the blufl" 

 above the sand is a favorite location for them. 



A bull and cow, which, seem to be the same as were seen this morning when the 

 young cow was shot, are now out in the sea, a rod from the shore. They come ashore 

 together and the bull drives a bachelor away. It is evidently the same pair. The 

 male has a big cut in the side. At 4 p. m., on our return, both are gone again. 



SIVUTCH BOOK. 



With a glass from the rock pile back of the Eeef one can make out about 27 ' 

 harems of moderate size scattered along the beach of the concave western shore of 

 Sivutch islet. About 150 bachelors are hauled up on the north end. The bulk of 

 them seem small. No drives are made from this island, though occasional killings 

 are made there in the early spring, the first bachelors usually hauling out there. 



AEDIGUEN. 



Harem A had 7 cows; B, 19; C, 29 only; D, 27. The young bachelor is apparently 

 gone. Harem E has 9 cows; F, 6; G, 9. One cow in D is wet. The cows are 

 asleep in lazy attitudes, but they waken occasionally and fight sleepily. 



The young bachelor has evidently returned. He is driven out of B into D by 

 the angry bull. Wherever he goes the cows are in a turmoil and bite at him. He is 

 now among the pups at the bottom of D. Passes a noisy cow, who strikes at him ; 

 tramples on pups of P aud goes on dragging his hind legs over pups and upsetting 

 them. He can be traced down to H, where he goes reluctantly.^ 



The bull calf paddles down to the harem at the very foot slowly and reluctantly, 

 trampling all the pups he can ; they recover themselves rapidly. 



At a distance beyond harem there is a big black bull, with a cow and pup, 

 evidently a new harem, which we may call X, 



The old cow with the green fur, now silvery, formerly in A, is now in charge of 

 an idle bull a rod higher up. We may call this harem Y. 



JULY 18. 



The day was spent on board the Albatross dredging 6 miles off Zapadni Head. 

 The weather was very rough. Heavy rain fell during the whole day. Dr. Stejneger 

 remained on board the vessel, it being arranged that the Albatross should sail in 

 the night for Unalaska to take coal and steam for the Commander Islands. Mr. 

 Townsend also remained to accompany the vessel to Unalaska, where he will remain 

 until August 10, getting information among the ofiicers of the sealing vessels which 

 are now coming in to fit up for the Bering Sea cruise. 



JULY 19. 



Dr. Jordan and Mr. Clark visited Gorbatch rookery. Weather very disagreeable, 

 with alternate fog and rain, southeasterly winds. Thermometer 42; barometer 30.20. 



1 Inspection of this island in August, 1896, showed the rookery to be much larger, and in 1897 a 

 count made from a boat showed 102 harems. 



" This may have been a yearling cow. In 1897 a young cow of this sort was seen to shift about 

 among the harems under Lnkaniti Cliff for about 10 days, always avoiding the attentions of the bulls, 

 and consequently apparently attacked by them.
