WASPS, SOCIAL AND SOLITARY 



full of energy that we stopped to watch them, and this 

 was our introduction to the study of these "bold sons of 

 air and heat," although a perusal of Fabre's fascinating 

 "Souvenirs Entomologiques " had prepared us to feel a 

 lively interest in them. We -were at our summer home 

 near Milwaukee, where meadow and garden, with the 

 wooded island in the lake close by, offered themselves as 

 hunting grounds, while wasps of every kind, the social-

The Vespas that had aroused our interest received our 

 first attention, and a nest in the ground proved to be a most 

 convenient arrangement. Experiments that would have 

 been dangerous to life and limb had we tried them with 

 a paper nest hanging in the open, were easy here so long 

 as we kept calm and unflurried. Intent upon their own 

 affairs, and unsuspicious of evil, perhaps because they
