SYNONYMY OF TACHYCINETA THALAS8INA 419 



ately to disperse in search of food, the occupation of their day. 

 To those who may have had an opportunity of observing the 

 phenomenon of a waterspout, the similarity of evolution, in the 

 ascent of these birds, will be thought surprisingly striking. 

 The descent, which regularly takes place at sunset, is con- 

 ducted in much the same way, but with inconceivable rapidity. 

 And the noise which accompanies this can only be compared 

 to the falling of an immense torrent, or the rushing of a violent 

 gust of wind. Indeed, to an observer, it seems wonderful, that 

 thousands of these birds are not destroyed, in being thus 

 propelled to the earth with such irresistible force." The nar- 

 rative does not state whether or not it was a good day for 

 Swallows.
