36 THE FUR SEALS OF THE PUIHILdF ISLANDS. 



B. THE FUR-SEAL ROOKERIES. 

 THE BKKEDING GROUNDS. 



WliciTVcr tliere is :i rocky beacli of .some breadth or a sloping rocky liill on the 

 Pribilof Islands the fur seals have located their breedini;- j^ronnds, or "rookeries," as 

 they are called. The best type of rookery ground is a moderate slope covered with 

 (•oarse rocks and descending to a beach of shingle or rounded bowlders. On tliese 

 beaches their gregarious habits cause the animals to crowd together in clo.se-sct 

 masses. The limits of tlio rookeries are defined by abrupt cliffs or headlands, which 

 cut ofi' the beaches, by inaccessible clitts that rise in the rear and by intervening sand 

 beaclies. They seldom extend far back from tbe sea under any condition, as access 

 to the water is an essential feature. 



THE HAULING GROUNDS. 



Adjoining the breeding grounds and an essential part of each rookery are what 

 are known as the "hauling grounds" of the bachelors, lre(iuented by tlie young males 

 of the ages of a years and under, the.se classes being strictly excluded from the breed- 

 ing grounds. These hauling grounds are usually located on sandy beaches bordering 

 the breeding grounds or on the Hat "parade" grounds above and in the rear of the 

 harems. In most cases the bachelors are foi-ced to encircle the end of the breeding 

 grounds to reach their locations in the rear, but in some cases neutral strips or run- 

 ways are left among the harems through which the bachelors haul out unmolested. 

 Not infrequently the bachelors seek to use runways which are not recognized as 

 neutral, and they are summarily thrown out by the harem masters. This leads to 

 confusion and fighting among the bulls, and the consequent destruction of females 

 and young pups. In many cases the hauling grounds are at a considerable distance 

 from the breeding grounds, but even where they are located immediately in the rear 

 of the hai'ems, a bntfer of idle or reserve bulls keeps them at a safe distance. The 

 young males have a wholesome and well-defined fear of the bulls, which experience 

 amply justifies. 



In the present depleted condition of the fur-.seal herd much ground once occu]iied 

 has been abandoned. The tendency of the auimals, in obedience to their gregarious 

 instincts, is to crowd together, and as their numbers decrease the rookeries shrink 

 np. With the restoration of tlie herd these abandoned grounds will undoubtedly be 

 reoccupied. It is probable that the occupation of absolutely new ground could only 

 result from an overcrowdeil condition of the rookeries. Not all the available space on 

 the islands was ever occupied even in the time of greatest expansion, as there are 

 long stretches of suitable beach line on which seals have never been known to breed. 



THE ST. PATTL ROOKERIES. 



The following is a brief description of the breeding rookeries of St. Paul Island, 

 beginning at Northwest Point :

 Northeast Point. It extends from the vicinity of Cross Hill, at the termination of the 



* The different fur-seal rookeries have for the most part retained their picturesque Russian names. 

 It is very desirable that they should contiuuo to do so, and it would be appropriate if Russian equiva- 

 lents were substituted for tlie few ICnglish names which have c.omo into use. In tlie spelling of the 

 Russian names we have followed the present atecptrd uuothods of transliteration uuder the advice of
