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 York, Sept. 19 th, 1810. 

 "DEAR SIR, 



"!T gives me much pleasure to reply to your letter of the 

 twelfth instant, asking of me information concerning the Grouse 

 of Long island.
