SIVUTCH KOCK AND ARDIGUEN. 321 



and flat, the lauding is easy. Here the seals come and go all the time, and the blntt' 

 above tlie sand is a favorite location for them. 



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

 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 lias a big cut iu the side. At i p. m., on our return, both are gone again. 



SIVLTTCH ROCK. 



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

 harems of moderate size scattered along the beach of the concave western sliore 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 iu the early spring, the first bachelors usually hauling out there. 



ARDIGUEN. 



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 iu 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 iu 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 F and 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 eau; they recover themselves rapidly. 



At a distance beyond harem L' 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, uow 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 ou board the AIbatro.s.s dredging (> miles oft' 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 iu 

 the night for ITnalaska 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 iuformatiou among the officers 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. 



' 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. 



- Thi.s may liave been a yearling cow. In 1897 a young cow of this sort was seen to shift about 

 amouj^ the harems under Lnkauiu CliU' for about 10 days, always avoiding the attentions of the bulls, 

 and eousequeutly apparently attacked by them.
