108 UP AND DOWN THE BROOKS. 



do through their beaks. At other times he 

 raised his head above the shoot, but the hinder 

 part of his body was continually elevated above 

 the fore part, so as to give him the appearance of 

 being just ready to turn a somersault. 



I thought that he was succeeding finely, but, 

 about three quarters of an hour after he first 

 entered into the business of making this batch of 

 foam, the Frog-hopper larva left the place alto- 

 gether and wandered to the end of the shoot, 

 where were some leaves. He still retained some 

 moisture on the under part of his body, but why 

 should he waste the bubbles he had been mak- 

 ing ? There they were, a pile of froth, waiting 

 for him while he crawled over the leaves. I 

 picked him up and put him back in his place, 

 but he would not stay there. Away he went 

 toward the leaves again. 



I put him back a second time, and again he 

 fell into the water. This second bath sobered 

 him, I think, for he recommenced work. Per- 

 haps the reason why he left his froth was that he 

 remembered that he had not explored the shoot, 

 and, inasmuch as he did not expect to make any 

 more journeys after the froth had once closed 

 over his head, he thought he would stop work and 

 travel a little. This was what I thought at first. 

 But after he had made another pile of froth 

 about as big as the former one, he again left it 

 and wandered off.
