forests under the lovely stars, are awakened by howlings as fantastic
as disagreeable. There is everything in this morning concert: clucking,
grunting, croaking, sneering, barking, and almost "speaking," if one
may make use of this word, which completes the series of different
noises.

There are the monkeys who thus salute the daybreak. There we meet the
little "marikina," the marmoset with a speckled mask; the "mono gris,"
the skin of which the Indians use to recover the batteries of their
guns; the "sagous," recognizable from their long bunches of hair, and
many others, specimens of this numerous family.

Of these various four-handed animals, the most remarkable are decidedly
the "gueribas," with curling tails and a face like Beelzebub. When the
sun rises, the oldest of the band, with an imposing and mysterious
voice, sings a monotonous psalm. It is the baritone of the troop. The
young tenors repeat after him the morning symphony. The Indians say
then that the "gueribas" recite their _pater-nosters_.

But, on this day, it seemed that the monkeys did not offer their
prayer, for no one heard them; and, meanwhile, their voice is loud, for
it is produced by the rapid vibration of a kind of bony drum, formed by
a swelling of the hyoides bone in the neck.

In short, for one reason or for another, neither the "gueribas," nor
the "sagous," nor any other four-handed animals of this immense forest,
sang, on this morning, their usual concert.

This would not have satisfied the wandering Indians. Not that these
natives appreciate this kind of strange choral music, but they
