BIRDS OF THE CAMBRIDGE REGION. 53 



including the Golden-winged and Nashville Warblers ; but the Wood Ducks that 

 used to breed in the Waverley Oaks, the Woodcock that formerly haunted the 

 course of the brook so numerously in spring and summer, the White-eyed Vireos 

 which I have found nesting near the shores of the upper pond, and the Olive- 

 sided Flycatchers whose clear, wild notes once mingled with the sound of the 

 waterfall, have all, I fear, departed never to return. 



The Wren Orchard. 



This name originated, I believe, in the fertile brain of my friend, 

 Mr. Frank BoUes, who during the latter years of his brief life, when he was 

 devoting himself especially to nature studies and charming us all with his force- 

 ful, sympathetic, and altogether delightful essays relating thereto, was much 

 given to frequenting the old orchard and its immediate surroundings. It is 

 wholly composed of venerable apple trees which cover two or three acres of 

 sloping ground lying just to the southeastward of Arlington Heights and about 

 midway between Prospect Street, Belmont, and Spring Street, Arlington. 

 When I visited it last, two or three summers ago, it had not changed greatly 

 in general character or appearance since I first saw it in 1867. Even at that 

 now remote time most of the trees were far advanced in decay. Owing partly 

 to this fact, and partly also to its remoteness from frequented highways and its 

 proximity to extensive woods, the Wren Orchard has long furnished congenial 

 breeding places for such hole-nesting species as the Screech Owl, the Downy 

 Woodpecker, the Flicker, the House Wren, the Chickadee and the Bluebird, 

 while I have known the locally rare Crested Flycatcher to be found there in 

 summer.
