Elephant Seals of Guadalupe Island 



lifted from the flooring. The animals often go to 

 sleep under water, stretched out on the floor of the 

 pool. 



When the Albatross left Guadalupe on March 

 4, 1911, there were not fewer than one hundred 

 and twenty-five elephant seals at the rookery. As 

 the number of adult females present was consider- 

 ably less than the number of adult males, and less 

 than half the number of yearlings, there was rea- 

 son to believe that the female portion of the herd 

 would be better represented before the end of the 

 month. The present size of the herd summer of 

 1912 may therefore be estimated at one hundred 

 and fifty animals of all classes. 



Eleven days later, when the Albatross reached 

 San Cristobal Bay, on the peninsula, I examined 

 the site of the old rookery at that locality without 

 finding any indication that it had been occupied. 

 We found no signs of elephant seals at either San 

 Benito or Cedros Islands, where the ship called on 

 the voyage southward. I examined the shores of 

 San Benito very thoroughly. Both of these islands 

 were formerly breeding resorts of the species. 



We may now safely assume that the Northern 

 elephant seal exists only on Guadalupe Island, and 

 that we have ascertained about how many of its 

 race remain. We have learned from examination
