was to imprison the young males in the "Salt

 during the period of pelagic sealing, and thus pre-

 individual at a time, and with a gate across the base 

 of each arm. It was perfectly easy to drive the 

 animals up to and along the lane, but, arrived at 

 the barriers, each insisted on blindly following the 

 one before. Nothing, in fact, would induce him to 

 pass through an open gate if his predecessor had 

 gone by way of a closed one, and he would stubbornly 

 push against the latter until it was opened. 



The stupidity of the Fur Seal under these new His 

 conditions thus contrasted strongly with its in- Uachable
