Migration Tables for April and May
AT our request, Dr. A. K. Fisher has furnished the following notes on the spring migration. They are based on fifteen years′ observation and will therefore prove valuable as a guide, and interesting for comparison, to other observers. A list of Mississippi Valley migrants, which we expected to receive, unfortunately arrived too late for publication, while a list from Philadelphia, by Mr. Witmer Stone, is necessarily omitted for lack of space. — Ed.
