should float quietly in a canoe past its haunts. Its color shows to best 

 advantage against the dark background of its home, and its every 

 movement is a delight to the eye.

The history of Swainson's Warbler is very similar to that of Bach- 

 man's Warbler. It was discovered by Dr. Bachman near Charleston, 

 South Carolina, in 1832, and for somewhat over fifty years was prac- 

 tically a lost species, but proves now to be a common bird in some 

 parts of its range. Its rediscovery near Charleston by Mr. A. T. Wayne 

 and Mr. Brewster is recounted by the latter in an article * which ade- 

 quately portrays the bird, its habits and haunts. It lives on and near 

 the ground, and, according to Mr. Brewster's experience, four things 

 seem indispensable to its existence — " water, tangled thickets, patches 

 of cane, and a rank growth of semi-aquatic plants." Its song, which 

 is highly ventriloquial, is described by the same author as "a series of 

 clear, ringing whistles, the first four uttered rather slowly and in the 

 same key, the remaining five or six given more rapidly, and in an 

 evenly descending scale. ... In general effect it recalls the song of 

 the Water Thrush {Seiurus noveboracensis). It is very loud, very rich, 

 very beautiful, while it has an indescribable tender quality that thrills 

 the senses after the sound has ceased."
