of the field mouse, she probably finds it already 

 provided with material suited for her use. This

 cut into short lengths. The mouse is very par- 

 ticular in the selection of material, taking the 

 withered blades from the base of a tussock and 

 dividing them lengthwise as well as cross-wise in 

 order to have them perfectly ductile and capable

 Humble Bee likes. Sometimes she mixes fragments

She next sets off on a hunt among the flowers, 

 and comes back a little later with her thighs bulging 

 with masses of pollen and her honey-crop filled

 In this cell she lays about a dozen eggs, and then 

 closes in the top with a dome of wax. She also 

 constructs a pot of thin wax to contain honey, 

 which is placed in the doorway of the nest-chamber 

 and filled with honey. The honey-pot is about
