BUTTERFLIES OF MT. HOOD 163 



for a twinkle of merriment in an elephant's eye. 

 It was at Bamum's Circus several years ago. 

 I remember the scene well. The keeper had just 

 set down for one of the elephants a bucket of 

 water, which a perspiring and important youth 

 had brought in. The big beast sucked the water 

 quietly up — the whole of it — swung gently 

 around to thank the perspiring boy, then soused 

 him, the whole bucketful ! Everybody roared, and 

 one of the elephants joined in with trumpetings, 

 so high and jolly was the joke. 



The elephant that played the trick looked 

 solemn enough, except for a twitch at the lips 

 and a glint in the eye. There is something of a 

 smile about every elephant's lips, to be sure, and 

 fun is so contagious that one should hesitate 

 to say that he saw the elephant laugh. But if 

 that elephant did not laugh, it was not his 

 fault. 



From the elephant to the infusorian, the mi- 

 croscopic animal of a single cell, is a far call — to 

 the extreme opposite end of the animal king- 

 dom, worlds apart. Yet I have seen Paramecium 

 caudatum at play, in a drop of water under a 

 compound microscope, as I have seen elephants
