Caparo.
At daybreak this morning the monkeys roared much 
nearer to the house than we have before heard them. 
Carr said they were within a mile of us. We 
could distinctly hear the different notes of the roar
whereas previously it has been merely a medley of sound.
The opening notes sounded like bub-bub-bub-bub-bub 
followed by a prolonged roar. Mr. Chapman suggested
that the general effect was not unlike that of a 
number of hogs when about to be fed. Carr agreed to
this but it did not strike me as a happy
comparison although I could make out a slight
resemblance.
For the past four or five evenings we have heard
in the high woods near the road a prolonged screeching
which almost exactly resembles the sound of a distant 
steam whistle. This is made by a cicada which is
called the "six o'clock bug". It begins very regularly
within ten minutes of 6 P.M. and continues until
dark or later. Near at hand one hears a short
prelude to the whistle, consisting first of
a low slow rattle and then of a frying sound which
runs directly into the screech.
