HASTY OBSERVATION 261 



one carelessly disposed across the top of the bending 

 grass and daisies, but a few feet from where I sat, 

 my eye again came near being baffled. 



The little snake was probably lying in wait for 

 some insect. Presently it slid gently down into the 

 grass, moving so slowly as to escape any but the 

 most watchful eye. After its head and a part of

 leaves upon which it hops, though when spawning 

 in the little black pools and tarns in spring its color 

 is very dark, like the element it inhabits. 



One day, in my walk in the woods, I disturbed a 

 whip-poor-will where she sat upon her eggs on the

 view upon the ground in the woods. How well she
