THE SPRING MIGRATION OF 1901. 



WITH AN AVERAGE TABLE FOR LORAIN COUNTY, OHIO. 

 BY R. L. BAIRD. 



Beginning with New Year's day I spent every possible 

 minute that could be spared from other school work in the 

 field with note-book and field-glasses. As I was unable to

 from Oberlin to Beaver Creek, south of South Amherst, and 

 from there its course was followed to the lake. Through 

 most of this distance the creek flows through a wide valley 

 with steep sides, a large part of which is well wooded. In

For three miles south from Lake Erie there are compar-
