was to imprison the young males in the "Salt

 during the period of pelagic sealing, and thus pre- 

 vent their destruction at sea. Accordingly we Fencing a

reactions to external stimulus had been pre- 

 viously tested by us in an experiment devised to 

 separate the killables from the rest of the holostiaki. 

 For this operation we provided three runways 

 joined in the form of the letter Y, having an en-

 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
