1893                                                                     
Sept. 19.            
Boston to Portland Maine.
Sultry and rainy clearing at sunset.
Left Boston at 7.30 P.M. on Portland steamer. The sky was
clear and full of stars, but a dense fog hung low over the wat-
er.  As we were running down the harbor I heard migrating Warbl-
ers continually. They seemed to be wandering about aimlessly
in the fog.  After we were well out on the ocean they were also
heard at frequent intervals. There has been more or less of a
flight every night for the past week although the weather has
varied considerably. Most of the Warblers migrating of late
have been Black polls apparently. Their chirping is slightly
different from that of the other species.
