THE BLUE HUNTRESS

Close to tlic out-house, whose rough frame supports the 

 nursery of the bhie huntress, hes a heap of rich red-orange 

 clay, thro^Mi up from a pit on the trail to the forest. It 

 attracts a dozen busy mason-wasps who arrive from far and 

 near to gather up the pliable, ready-made mortar and bear 

 it away to their nests. We are concerned only with a single 

 member of the laboring crowd. She is at once distinct in 

 size. Her rich metallic color attracts our attention and holds

 large rocks to the insect, lend themselves admirably to the 

 needs of her nest. They lend a rough, rugged appearance 

 to the three-celled nursery, but form an impregnable barrier 

 against a host of enemies. 



The building material is laid on in irregular heaps. 

 They dry very rapidly as the work progresses, giving the 

 nest the appearance of a bit of fairy hill country covered 

 witli a thousand disorderly loads, spilled helter-skelter from 

 as many tiny dump carts. The wasp cares little for outside 

 appearances which are of no account. She is concerned

 stone work, even a sharp grain of sand overlooked, might
