egg masses with tiny tadpoles pendant 
from the original matrix, and other 
tadpoles just detached are to be noted 
clinging to leaves and sticks. Over on 
the mossy promontory under the jacks 
are wood frogs just coming out of the 
water, while in the pool near them are 
their young tadpoles in a school, proving 
their communal instinct as they swim 
hastily away from the approach of a 
spotted turtle. 
We not only see these hylas and toads 
and frogs as we stand before the case 
but in memory we hear them too, the 
blending of melodious trill and bawling 
call of one and another. They make 
the springtime vocal. How it is done is 
suggested for some of the species in the 
group — that little sac under the chin 
is blown up by Mr. Lovelorn until full 
of wind, like Shakespeare’s “lover, 
sighing like a furnace,” and, without 
opening the mouth, the penetrating 
notes issue forth, made by the vocal 
chords in the throat and reénforced by 
this vocal sac. I recall an experiment 
made by the Boy of Ten to settle a dis- 
pute as to whether the hyla or the toad 
made a certain bawling sound —a 
sound which comes to me faintly now as 
I remember and listen. It was on a still 
night, encamped by a mountain lake, 
when incessant amphibian calls of one 
kind or another made the principal night 
sounds. The boy crept far out onto a 
great rock, jutting into the lake. All 
about in the darkness had been the calls. 
Silence instantly ensued with his com- 
ing, but after a five minute’s wait, the 
calls began again. Softly lighting a 
-~andle, no fewer than six toads were dis- 
covered within the distance of a few 
feet. Presently one of the toads dis- 
tended his throat pouch and issued his 
song. Followed him another, and an- 
other — and the dispute was settled for 
good.
