UP AND DOWN THE BROOKS. 



came out of the " twig," for that was the brown 

 case, covering the pupa of one of the flies that 

 look like giant mosquitoes, the Tipulidce. 



Daddy Long-Legs the children call the fly re- 

 lated to this that passes the two earlier stages of 

 its life in the ground. " Crane-flies " others name 

 them, and the French cry " Tail- 

 leurs," or " Couturieres." I think 

 these water-flies sometimes drown 

 while struggling out of their pupaB- 

 cases. At least I have found one 

 such a position as to convey 

 that idea, and the won- 

 der is that any of them 

 get out alive when 

 there is nothing near 

 to be grasped by the 

 insect during the ope- 

 ration. 



If you know where 

 to look you may find 

 other Tipulid larva? 

 near here. A few live- 

 oak-trees are scattered 

 along the banks. Some of the trees are old, for 

 holes in their trunks show the rotting wood 

 within. One day as I wandered here I spied in 

 a tree a hole about on a level with my head. 

 The hole extended through the tree so that I 

 could view the interior. Black-bottomed with the 



Tipulid Fly, somewhat larger 

 than mine.
