with shrieks of consternation or else falls paralysed in their
path to be instantly torn to pieces and devoured.

A slight rustling sound in the foliage above me made me start and
cast up my eyes. High up, where a pale gleam of tempered sunlight fell
through the leaves, a grotesque human-like face, black as ebony and
adorned with a great red beard, appeared staring down upon me. In
another moment it was gone. It was only a large araguato, or howling
monkey, but I was so unnerved that I could not get rid of the idea that
it was something more than a monkey. Once more I moved, and again, the
instant I moved my foot, clear, and keen, and imperative, sounded the
voice! It was no longer possible to doubt its meaning. It commanded me
to stand still--to wait--to watch--to listen! Had it cried "Listen! Do
not move!" I could not have understood it better. Trying as the suspense
was, I now felt powerless to escape. Something very terrible, I felt
convinced, was about to happen, either to destroy or to release me from
the spell that held me.

And while I stood thus rooted to the ground, the sweat standing in large
drops on my forehead, all at once close to me sounded a cry, fine and
clear at first, and rising at the end to a shriek so loud, piercing, and
unearthly in character that the blood seemed to freeze in my veins,
and a despairing cry to heaven escaped my lips; then, before that long
shriek expired, a mighty chorus of thunderous voices burst forth around
me; and in this awful tempest of sound I trembled like a leaf; and the
leaves on the trees were agitated as if by a high wind, and the earth
itself seemed to shake beneath my feet. Indescribably horrible were my
sensations at that moment; I was deafened, and would possibly have been
maddened had I not, as by a miracle, chanced to see a large araguato
on a branch overhead, roaring with open mouth and inflated throat and
chest.

It was simply a concert of howling monkeys that had so terrified me! But
my extreme fear was not strange in the circumstances; since everything
that had led up to the display--the gloom and silence, the period of
suspense, and my heated imagination--had raised my mind to the highest
degree of excitement and expectancy. I had rightly conjectured, no
doubt, that my unseen guide had led me to that spot for a purpose;
and the purpose had been to set me in the midst of a congregation of
araguatos to enable me for the first time fully to appreciate their
