THE ASIATIC FUR-SEAL ISLANDS. 



But even at closer range it is sometimes difficult to distinguish the sexes. On 

 the killing ground, where tbe teeth of the seals are easily seen, there is, of course, no 

 special difficulty, and mistakes are seldom made; not so in the drives, however. 



During a small drive at Glinka, Copper Island, August 8, 1895, about 300 seals 

 were made to cross the mountain pass (about 800 feet) in three main divisions, no less 

 than 30 grown men taking part in the driving. Halfway up one of the men declared 

 that there was a " matka" in the drive. It was questioned, but upon closer scrutiny 

 he was found to be right. It was not until the final sorting before the killing took 

 place tbat several females were discovered in the flock. 



As an additional indication of the lack of definition of the different classes of 

 seals as expressed in their sizes, I append a few tables of measurements taken from 

 the freshly killed animals.
