During some nights they seemed to be passing in end- 
of ISMZ 
less process ion, yet rarely in close c moanionship. This I 
inferred from, the fact that it was exceptional to near more 
than one of them in any given direction at any one time and 
equally so for many minutes to elapse when none were noted. 
Hot infrequently the last faint call of one that was just 
passing out of e rshot to the southward would be almost 
immediately foil wed by the first audible cry of another 
appro 'Ching from the northward. Flying thus singly, at 
widely spaced intervals, yet perhaps within distant hearing 
of one another, mingling their crisp, incisive voices with 
the feeble lisping ■ones of innumerable migrating - rblers, 
the mysterious bird® would journey almost ceaselessly south- 
w rd along aerial oathway s, lighted only by the moon or by 
myriads of t inkling stars. 
Their calls, ’Which were seldom given of turner than 
once every eight or ten second® and gonetimes much less 
frequently, reminded me by turns of those of certain of our 
Jnrblers, of the autumnal note of the Rose-breasted Grosbeak 
and of the loud, explosive cry of the Created Flycatcher. 
On the whole, however, they resembled most closely the night 
c 11s of the Hermit Thrush. Indeed I was inclined for a 
time to refer them to that species until 1 heard that the 
birds making them habitually departed for the ->outh before 
many * if any, of the Hermits had left their breeding-grounds.
