THE RETURN OF THE BIRDS. 29 



more marked and defined than that of the birds. Show 

 a botanist a landscape, and he will tell you where to 

 look for the lady's-slipper, the columbine, or the 

 harebell. On the same principles the ornithologist 

 will direct you where to look for the greenlets, the 

 wood-sparrow, or the chewink. In adjoining coun- 

 ties, 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 dis- 

 tant, 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 yel- 

 low warbler, and many others, and find in their stead 

 the wood-thrush, the chewink, the redstart, the yel- 

 low-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 

 distribution is very marked. South of the village I 

 invariably find one species of birds, north of it an- 

 other. In only one locality, full of azalea and swainp- 

 huckleberry, I am always sure of finding the hooded 

 warbler. In a dense undergrowth of spice-bush, 

 witcL-hazel, and alder, I meet the worm-eating war- 

 bler. In' a remote clearing, covered with heath and 

 fern, with here and there a chestnut and an oak, I go
