small pool just below the rapid, the immense head of a hippopotamus
close to a perpendicular rock that formed a wall to the river, about six
feet above the surface. I pointed out the hippo to old Abou Do, who had
not seen it. At once the gravity of the old Arab disappeared, and the
energy of the hunter was exhibited as he motioned us to remain, while he
ran nimbly behind the thick screen of bushes for about a hundred and
fifty yards below the spot where the hippo was unconsciously basking,
with his ugly head above the surface. Plunging into the rapid torrent,
the veteran hunter was carried some distance down the stream; but,
breasting the powerful current, he landed upon the rocks on the opposite
side, and, retiring to some distance from the river, he quickly advanced
toward the spot beneath which the hippopotamus was lying. I had a fine

Abou Do now stealthily approached the ledge of rock beneath which he had
expected to see the head of the animal. His long, sinewy arm was raised,
with the harpoon ready to strike, as he carefully advanced. At length he
reached the edge of the perpendicular rock. The hippo had vanished, but,
far from exhibiting surprise, the old Arab remained standing on the
sharp edge, unchanged in attitude. No figure of bronze could have been

of the water was still barren, when suddenly the right arm of the statue
descended like lightning, and the harpoon shot perpendicularly into the
pool with the speed of an arrow. What river-fiend answered to the
