For purpose of comparison, I give below the earliest and latest 

 recorded dates of arrival for a number of species at Mt. Carmel, 

 Illinois ; Wheatland, Indiana ; St. Louis, Missouri, and Washington, 

 D. c.^ — localities in nearly the same latitude, i'or the latter, I am 

 indebted to Mr. H. W. Henshaw and Mr. Wm. Palmer, of Wash- 

 ington, who have kindly given me their records ; the data for St. 

 Louis, I have compiled from Mr. Otto Widman's "General Notes 

 and Weather Report from St. Louis," published in Bulletin No. 1 

 of the Ridgway Ornithological Club, of Chicago," which abound 

 with valuable data pertaining to the subject of bird-migration in 

 the Mississippi Valley.
