THE NATURALIST'S SUMMER- 

 EVENING WALK.

When day declining sheds a milder gleam. 

 What time the May-fly* haunts the pool or stream f 

 When the still owl skims round the grassy mead.

 or six hours. They usually begin to appear about the 

 4th of June, and continue in succession for near a fort- 

 night. See Swammerdam, Derham, Scopoli, ^c.

 by no incubation or attendance about the nutrition of its 

 young, it wanders without control.
