tween them ; but I am induced to think that they keep apart from the old 
birds during the first winter, when I have thought I could yet perceive an 
inferiority in their flight, as well as in the loudness of their notes.. 
This species has no song, properly so called, but merely a twitter of short 
lisping notes. In autumn it at times alights on trees preparatory to its 
departure. On such occasions the individuals, often collected in great 
numbers, take up the time chiefly in pluming themselves, in which occupa- 
tion they continue for hours. 
I must conclude with assuring you that in my opinion, no difference 
whatever exists between the Bank Swallow of America and that of Europe. 
The birds from which I made the drawing for my plate were procured on 
the banks of the Schuylkill river in 1824.

PLATE LI. 
On the afternoon of the 20th of October, 1819, 1 was walking along the 
shores of a forest-margined lake, a few miles from Bayou Sara, in pursuit of 
some Ibises, when I observed a flock of small Swallows bearing so great a 
resemblance to our common Sand Martin, that I at first paid little attention 
to them. The Ibises proving too wild to be approached, I relinquished the 
pursuit, and being fatigued by a long day’s exertion, I leaned against a tree, 
and gazed on the Swallows, wishing that I could travel with as much ease 
and rapidity as they, and thus return to my. family as readily as they could
