starting the Irogs calling again at distances of from 
fifty to three feet, after they had been silent for a 
minute or so. One individual was recorded as having 
called 74 times in one period of song. 
The frogs definitely associate together for singing, 
whether because of the presence of females or for 
companionship. The latter probably plays a con- 
siderable share in the performance, as is evidenced by 
the quick response to an imitation of the call. Five 
such singing groups were definitely located. Of these 
the first contained seven individuals, the second con- 
tained three, the third contained eight, the fourth 
contained three and the fifth, which was just across 
an uncrossable creek, contained at least six. Only 
once was a single individual noted in song alone, and 
that was a frog which called three times in a spot a 
half-mile distant from any others and was never heard 
from again. 
The locations of the groups were fixed, and during 
our stay did not change a particle. Night after night 
a group would be in exactly the same area, though the 
individuals composing it shifted position a bit. 
The time of singing was remarkably constant. On 
every night but one the chorus started between ten 
and fifteen minutes before sundown. On the one ex- 
ception, a clear dry night with a bright moon, the 
first songs were not heard until twenty minutes after 
sundown. 
The carrying power of the song was excellent. A 
chorus was plainly heard as an entity over 800 paces 
away, with two patches of woods and a brushy swamp 
intervening. The wind was negligible. Individual 
voices were distinguishable 754 paces away down a 
straight road, with a light wind blowing from the 
observers toward the frogs. 
The exact positions of ten individuals were located, 
of which seven were captured. High-bush Blueberry 
tangles festooned with Green Briars made further
