   The mysteries of migration are immeasurable and some
of them well nigh inscrutable. Last night the lisping
of Warblers passing overhead was almost incessant from
9 to 11 o'clock. To-night with precisely similar conditions
of weather & temperature did not bring one single
bird so far as my ears could detect.

    A Pickering's Hylas gave the autumn call to-night
in the trees near our house. It is the first time I 
have heard its voice since last May.

   Blue Jays were heard screaming and chuckling in
several places this afternoon. The form seen at Goose Pond
kept well together and acted like the members of one
brood but they were in full plumage apparently.
