15 



wires along country roads in the vicinity of the lake 

 marshes. In July 1894 I saw about six hundred 

 together on the wires a few miles west of Sandusky 

 and in 1896 about twelve hundred a few miles east of 

 the city. Mr. Marion W. Bacome recently told me of 

 seeing one time between Bellevue and Fremont a much 

 greater number of "common" swallows than this. 

 There were "at least three birds to the foot for a 

 distance of nearly four hundred feet" and he thinks 

 nine wires, making not less than ten thousand 

 swallows.
