XI THE SCIENCE OF INSTINCT 157

 for all the household working under the shade of 

 the plane trees formed a circle round the Sphex. They 

 wonder at the audacious tameness of the insect, noways 

 disturbed by the gallery of interested spectators. 

 All are struck by her proud and robust bearing, as, 

 with raised head and the victim's antennae well 

 grasped by her mandibles, she drags after her the

 feel some regret. " Ah, had I but some live ephip-

 brought back three ephippigers as good as heart 

 could wish — two females and one male. How came 

 these insects at hand just at the right moment for 

 an experiment vainly tried twenty years before ? 

 This is another story. A southern shrike had nested 

 on one of the tall plane trees in the avenue. Some 

 days before the Mistral, the rude wind of our parts, 

 had blown so violently that branches bent as well 

 as reeds, and the nest overturned by the undulations

 The next day I found the brood on the ground — 

 three killed by the fall, the fourth still alive. The 

 survivor was entrusted to Emile, who thrice a day 

 went cricket-hunting on the turf in the neighbour- 

 hood to feed his charge. But crickets are not very 

 large, while the nestling's appetite was. Something
