WAYS OF THE OWL. 195 



fumes of camplior, ammonia, and other disagree- 

 able and unusual smells, but they failed to show 

 that they perceived them unless the fumes were

 They were utterly indifferent to it until the cat 

 made the basket rock, when both of them fled

 of smell, but the presence of an appreciation of 

 color. I have fancied that an appreciation of 

 color is also shown by barred owls in their fre- 

 quent selection of beech trees as nesting-places, 

 by great-horned owls in their choice of brown- 

 trunked trees, and by Snowdon in an apparent 

 preference for gray backgrounds.

 to select protective backgrounds is to be joined

 swaying from side to side as he rocks from one 

 foot to the other, to a slim, sleek, brown post
