Before I enter on a detail of the observations which I have myself 
personally made on this singular species, I shall lay before the reader a 
comprehensive and very circumstantial memoir on the subject, communi- 
cated to me by the writer. Dr. Samuel L. Mitchill of New York, whose 
exertions, both in his public and private capacity, in behalf of science, 
and in elucidating the natural history of his country, are well known ; 
and highly honorable to his distinguished situation and abilities. That 
peculiar tract generally known by the name of the Brushy Plains of 
Long Island, having been, for time immemorial, the resort of the bird 
now before us, some account of this particular range of country seemed 
necessarily connected with the subject, and has accordingly been oblig- 
ingly attended to by the learned professor.

instant, asking of me information concerning the Grouse of Long 
Island.

Grouse, inhabit chiefly the forest-range. This district of the island 
may be estimated as being between forty and fifty miles in length, 
extending from Bethphage in Queens county to the neighborhood of the 
court-house in Suffolk. Its breadth is not more than six or seven. For 
although the island is bounded by the Sound separating it from Con- 
necticut on the north, and by the Atlantic Ocean on the south, there is 
a margin of several miles on each side in the actual possession of human 
beings. 
" The region in which these birds reside, lies mostly within the towns 
of Oysterbay, Huntington, Islip, Smithtown, and Brook Haven ; though 
it would be incorrect to say, that they were not to be met with some-
