Before I enter on a detail of the observations which I have 
myself personally made on this singular species, I shall lay be- 
fore the reader a comprehensive and very circumstantial me- 
moir on the subject, communicated 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 eluci- 
dating the natural history of his country, are well known; and 
highly honourable 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 obligingly attended to by the learn- 
ed professor. 
“New Fork, Sept. 19th, 1810. 
•‘Dear Sir, 
“It gives me much pleasure to reply to your letter of the 
twelfth instant, asking of me information concerning the Grouse 
of Long island.
