The Life of the Fly

 with two iron-shod sticks in its throat, it can 

 easily descend to such depths as it pleases. 

 The need for greater quiet and a less trying 

 temperature calls for the deepest possible 

 home : the lower down it is, the better for the 

 welfare of the worm and the pupa, on con-
