look-out for some time for a good camping-place, as
it was their usual hour to stop. No opening, however, appeared for
several miles. The banks on both sides were thickly-wooded to the
river's edge, and the branches of the trees even drooped into the water.
At length they came in sight of a natural raft that had been formed by
driftwood in a bend of the stream; and as the logs lay thickly together,
and even piled upon each other, it appeared an excellent place to encamp
on. It was, at all events, better than to attempt to penetrate the thick
jungles which met them everywhere else; and so the balza was directed
towards the raft, and soon floated alongside it.

They had already got ashore on the raft, which was dry and firm, and
would have served their purpose well enough; when, all at once, Guapo
was heard uttering one of those exclamations, which showed that all was
not right. The rest looked towards him for an explanation. He was
standing by the edge of the floating timber, just where the balza
touched it, with his arms stretched out in an attitude that betokened
trouble. They all ran up. They saw what was the matter at a glance.
Thousands of red ants were climbing from the raft to the balza!
Thousands,--nay, it would be nearer the truth to say millions!

At one glance Don Pablo saw that it would be a terrible calamity, should
these creatures gain a lodgment on the balza. Not only were they the
dreaded stinging ants, but in a short time nothing on board would be
left. In a few hours they would have eaten all his stores,--his bark,
his vanilla, and his roots. Already quite a number had got upon the
canoe, and were crossing it toward the body of the balza.

Without saying another word, he ordered all to get on board as quickly
as possible, each taking some utensil that had already been carried on
shore. He and Guapo flew to the poles; and, having hastily unfastened
and drawn in the cable, they pushed the balza out into the stream. Then
while Guapo managed the great oar, Don Pablo, assisted by Leon and by
Dona Isidora, went to work with scoops and pails, dashing water upon the
ants; until every one of them had disappeared, drowned in the canoe or
washed off into the river. Fortunate for them, they had observed this
strange enemy in time. Had they not done so--in other words, had they
gone to sleep, leaving the balza where it was during the night--they
would have awakened in the morning to find their stores completely
