220 AMERICAN GAME. 
some stand perpendicular to the back. They are all 
adorned with an ample crest, pendulous, and running 
down the back of the neck. They are easily domesti- 
cated, but I do not know that they have been yet of 
much utility in this state, being more kept on account 
of their beauty, and few have been introduced except to 
our menageries; with a little trouble at first, they might 
form a much more common ornament about our artificial 
pieces of water. It is the only form of a Tree Duck 
common to this continent; in other countries there are, 
however, two or three others of very great importance 
in the natural system, whose structure and habits have 
yet been almost entirely overlooked or lost sight of. 
These seem to range principally over India, and more 
sparingly in Africa; and the Summer Duck is the soli- 
tary instance, the United States the nearly extreme 
limit, of its own peculiarities in this division of the 
world.” 
With this note I close this paper, expressing only the 
hope that the bird -will become more largely domestica- 
,ted ; as no more beautiful adornment can be conceived 
to the parks and shrubberies of gentlemen, such more 
especially as possess the advantages of small inland 
rivulets, or pieces of ornamental water, whether natural 
or artificial.
