Dear Sir: 
I have your letter of December 12th and am sending 
you a copy of Article 10 of Volume 14 of our Bulletin in 
which you will find Professor Gross' data with regard to 
the prairie hen in Illinois.   The index to the volume re- 
fers under this head to pages 408, 416, 417, 418, 420, 4 7, 
and 439.   Professor Gross' field notes would contain only 
more detailed information as to precise localities and situ- 
ations in which the species was noted. 
If I can give you any further information on the 
subject, I shall be pleased to hear from you. 
Very truly yours,
