pillage and murder them at discretion in all directions; thus, in
revenge, they will shoot a poisoned arrow at a stranger unless he is
powerfully escorted. The effect of the poison used for the arrow-heads
is very extraordinary. A man came to me for medical aid; five months ago
he bad been wounded by a poisoned arrow in the leg, below the calf, and
the entire foot had been eaten away by the action of the poison. The
bone rotted through just above the ankle, and the foot dropped off. The
most violent poison is the produce of the root of a tree, whose milky
juice yields a resin that is smeared upon the arrow. It is brought from
a great distance, from some country far west of Gondokoro. The juice of
the species of euphorbia, common in these countries, is also used for
poisoning arrows. Boiled to the consistence of tar, it is then smeared
upon the blade. The action of the poison is to corrode the flesh, which
loses its fiber, and drops away like jelly, after severe inflammation
and swelling. The arrows are barbed with diabolical ingenuity; some are
arranged with poisoned heads that fit into sockets; these detach from
the arrow on an attempt to withdraw them; thus the barbed blade, thickly
smeared with poison, remains in the wound, and before it can be cut out
the poison is absorbed by the system. Fortunately the natives are bad
archers. The bows are invariably made of the male bamboo, and are kept
perpetually strung; they are exceedingly stiff, but not very elastic,
and the arrows are devoid of feathers, being simple reeds or other light
wood, about three feet long, and slightly knobbed at the base as a hold
for the finger and thumb; the string is never drawn with the two
forefingers, as in most countries, but is simply pulled by holding the
arrow between the middle joint of the forefinger and the thumb. A stiff
bow drawn in this manner has very little power; accordingly the extreme
range seldom exceeds a hundred and ten yards.

The Bari tribe are very hostile, and are considered to be about the
