296 THE FUR SEALS OF THE PRIBILOF ISLANDS. 



Fewer idle adult bulls were seen on this rookery than on North. Only two were 

 noted, but there were from a dozen to fifteen young half bulls hanging about the rear 

 of the harems. 



The females seem to be a finer and larger lot than those on North rookery. Fewer 

 pups were seen. 



Passing by the hauling ground of Little East, from which the small group of 

 holostiaki had stampeded into the water, a seal, either a cow or a bachelor, was seen 

 lying in the shallow water, apparently in distress and unable to get on. It could not 

 be reached for examination and nothing could be done. 1 



EAST ROOKERY. 



The bowlder-strewn sloping shore extends from the beginning of Little East 

 rookery all the way down to East rookery, about a mile below Little East, and seems to 

 indicate that the two may have formed at one time one great rookery. East rookery 

 begins with a few scattered harems just beyond the point. Its greatest mass of 

 harems lies back on a gradual slope at the angle of the perpendicular rocky cliff, 

 which is here resumed and continues along the eastern side of the island. On the 

 narrow beach at the foot of this cliff the harems extend for a considerable distance, 

 gradually fading out. From the brow of the cliff, 100 to 150 feet high, there is a good 

 opportunity for observing and counting the seals. 



The following detailed count of harems was made by Mr. Clark: 2 



Detailed count of East rookery. 



Total cows 1,584 



Total harems 142 



Average size of harem 11 



Dr. Jordan's count gave 128 harems and 1,682 cows. The average of these two 

 counts gives 135 harems and 1,634 cows, which is very near to the population of this 

 rookery. 



Eleven idle bulls were counted on East rookery. In addition to these were a 

 number of bulls stationed along the water front, which were attempting to round up 

 and form harems of passing cows. 



1 Later observations show that the animal was affected by a form of temporary paralysis due to 

 fright. Several instancevS -were noted while making the counts of pups in October. The animals 

 always quickly recovered. 



2 It was found in 1897, when this rookery was more closely inspected, that a section containing in 

 this season about 100 cows was omitted from the count for 1896. The section lay in close proximity 

 to a hauling ground, and it was assumed without close inspection that no breeding seals were there.
