MASSED EOOKERY FORMATION. 539 



A fur-seal harem of 4 cows was located right, in the midst of the sea-lion cows. 

 The sea-lion pups were playing about among the seals and were driven off by them. 

 Other smaller harems of 1 and 2 were lower down on the beach. The animals appear 

 simply to ignore one another. 



NORTHEAST POINT KOOKERIBS. 



Northeast rookeries do not afford good opportunity for obsiervation, except from 

 the top of Hutchinson Hill, and there the distance is too great. The bulls occupy 

 the entire space at the foot of the hill, and are scattered over its slope to the very 

 summit. 



Along the bowlder beach below the hill are 5 groups of seals, evidently single 

 harems which have expanded beyond the control of a single bull, though one or two 

 of them seem to be still dominated by a single bull. On the outskirts lie other bulls, 

 however, which can not be displaced, and which will eventually have part of the lot. 

 Two of the bunches of seals number nearly 200 cows each, and the others number 

 over 100. There are doubtless small scattering harems between them, but they are 

 not visible, and probably have but 1 or 2 cows each. In these bunches we have 

 a segregation of the cows similar to that shown in the larger harems of from 15 to 45 

 on Lukanin. About the large bunches are small harems of 1 and 2 cows each which 

 have plainly been stolen and carried back. It may be that some of them have 

 wandered away and thus been captured. One cow with her pup is in charge of a bull 

 near the foot of the hill, far back from the shore and with a score of bulls intervening. 

 It is a mystery how she could reach her location. She could not have been stolen and 

 carried there. 



At intervals along the beach cows are similarly congregated in large harems. It 

 is plain that the tendency is for the landing cows to seek the crowded harems until 

 the mass becomes too large for the control of a single bull, when the outlying bulls 

 first occupy positions on the outskirts, and finally divide the bunch with the original 

 possessor. Cows also undoubtedly wander away while the bull is occupied, and are 

 taken up by bulls in the rear. It is certain that many of the cows are stolen from 

 these large harems and carried off bodily. 



A dead bull was seen just back of- the beach at the foot of the hill. His side 

 showed numerous cuts and scars as if he had been killed by his companions while 

 fighting, 



A large pod of bachelors are hauled out on the sand beach just opposite Gross 

 Hill and at some distance from the beginning of the rookery. I did not see anything 

 but old b.ulls there last year, but this is, doubtless, a regular hauling ground early in 

 the- season. 



Mr. Morton accompanied me to Hutchinson Hill. Eeturning, we found a little 

 blue fox pup lying outside a den. He looked sick — at least, was not afi aid of us — and 

 allowed himself to be handled and photographed. A second one, more timid but full 

 of cui'iosity, came out of the hole and in a few minutes was ready to play. Mr. 

 Morton offered it a piece of tobacco which it bit and tried to pull away. Almost 

 instantly the little fellow fell down in convulsions, becoming finally unconscious. It 

 revived in a few minutes, but declined to play further. The incident was a rather 

 unexpected argument against the use of tobacco,
