the shape of a nest of maribundi wasps, not the biggest kind, but
about the size of our hornets. We were at the time passing through
dense jungle, under tall trees, in a spot where the down timber,
holes, tangled creepers, and thorns made the going difficult. The
leading men were not assailed, although they were now and then cutting
the trail. Colonel Rondon and I were in the middle of the column, and
the swarm attacked us; both of us were badly stung on the face, neck,
and hands, the colonel even more severely than I was. He wheeled and
rode to the rear and I to the front; our horses were stung too; and we
went at a rate that a moment previously I would have deemed impossible
over such ground.

At the close of the day, when we were almost back at the river, the
dogs killed a jaguar kitten. There was no trace of the mother. Some
accident must have befallen her, and the kitten was trying to shift
for herself. She was very emaciated. In her stomach were the remains
of a pigeon and some tendons from the skeleton or dried carcass of
some big animal. The loathsome berni flies, which deposit eggs in
living beings--cattle, dogs, monkeys, rodents, men--had been at it.
There were seven huge, white grubs making big abscess-like swellings
over its eyes. These flies deposit their grubs in men. In 1909, on
Colonel Rondon's hardest trip, every man of the party had from one to
five grubs deposited in him, the fly acting with great speed, and
driving its ovipositor through clothing. The grubs cause torture; but
a couple of cross cuts with a lancet permit the loathsome creatures to
be squeezed out.

In these forests the multitude of insects that bite, sting, devour,
and prey upon other creatures, often with accompaniments of atrocious
suffering, passes belief. The very pathetic myth of "beneficent
