THE RETURN OF THE BIRDS. 21 



the wood-sparrow, or the chewink. In adjoining 

 counties, in the same latitude, and equally inland, but 

 possessing a different geological formation and differ- 

 ent forest-timber, you will observe quite a different 

 class of birds. In a land of the beech and sugar-maple 

 I do not find the same songsters that I know where 

 thrive the oak, chestnut, and laurel. In going from 

 a district of the Old Red Sandstone to where I walk 

 upon the old Plutonic Rock, not fifty miles distant, I 

 miss in the woods the veery, the hermit-thrush, the 

 chestnut-sided warbler, the blue-backed warbler, the 

 green-backed warbler, the black and yellow warbler, 

 and many others, and find in their stead the wood- 

 thrush, the chewink, the redstart, the yellow-throat, the 

 yellow-breasted fly-catcher, the white-eyed fly-catcher, 

 the quail, and the turtle-dove. 



In my neighborhood here in the Highlands the dis- 

 tribution is very marked. South of the village I inva- 

 riably find one species of birds, north of it another. 

 In only one locality, full of azalea and swamp huckle- 

 berry, I am always sure of finding the hooded warbler. 

 In a dense undergrowth of spice-bush, witch-hazel, and 

 alder, I meet the worm-eating warbler. In a remote 

 clearing, covered with heath and fern, with here and 

 there a chestnut and an oak, I go to hear in July the 

 wood-sparrow, and returning by a stumpy, shallow 

 pond. I am sure to find the water-thrush. 



Only one locality within my range seems to possess 

 attractions for all comers. Here one may study al-
