During the summer-months Sörling did not observe any Leopard-seals but in 

 the beginning of April the first ones appeared and the last were seen in the beginning 

 of October. About their habits Sörling has made several observations quoted in 

 the following pages. If it is fine weather the Leopard-seals seldom go ashore, but 

 are seen out in the fjords basking in the sun divingup and down with lazy move- 

 ments. If a snow-storm is raging they lie on the shore, but in the evenings and 

 early mornings they are always in the water feeding. 



When there was plenty of small pieces of drifting ice in the bay the Leopard- 

 seals liked to lie on such ice. They have on admirable faculty of jumping up on 

 such ice and shoot up like on arrow out of the water and up on the ice even if it 

 rises several feet above the surface, and when they have come up they crawl to the 

 top of the ice. Sometimes if the pieces of ice are too high above the water, or if
