70 NOTES ON NEW ENGLAND BIEDS 



wards in the same direction with its body and neck, so 

 as perfectly to resemble a stake aslant. If the bill had 

 made an angle with the neck it would have been be- 

 trayed at once. Its resource evidently was to rely on its 

 form and color and immobility solely for its concealment. 

 This was its instinct, whether it implies any conscious

 would have been seen here before the white man came. 

 It is a question whether the bird consciously cooperates 

 in each instance with its Maker, who contrived this 

 concealment. I can never believe that this resemblance 

 is a mere coincidence, not designed to answer this very 

 end — which it does answer so perfectly and usefully.

 and a half inches long, and not much else.

 contents of a stake-driver's stomach or crop. It is ap-
