 could devise nothing more ; my desire to be present 

 at the denoihnent had only added to former diffi- 

 culties. Well, let us try again. 



A luminous idea flashed upon me, bringing hope, 

 so naturally did it touch the very heart of the 

 question. Of course, it was the right thing and 

 must succeed. My disdained game must be offered 

 to the Cerceris in the heat of the chase — then, 

 absorbed and preoccupied, she will not discover its

 from the chase the Cerceris alights at the foot of the 

 incline at some distance from the hole, whither she

 was to deprive her of her victim, drawing it away by 

 one foot with pincers, and instantly throwing her the

 weevil which had replaced hers, flung herself upon
