afterwards they each grasped their own ankle with a hand, and
while one stood as firm as he could, the other swung himself
around on one leg, so as to strike the other's free leg, and try
to overthrow him. When these games had been played all around with
varying success, we had a novel kind of concert. Some placed a
leg across the knee, and struck the fingers sharply on the ankle,
others beat their arms against their sides like a cock when he
is going to crow, this making a great variety of clapping sounds,
while another with his hand under his armpit produced a deep
trumpet note; and, as they all kept time very well, the effect
was by no means unpleasing. This seemed quite a favourite
amusement with them, and they kept it up with much spirit.

The next morning we started in a boat about thirty feet long, and
only twenty-eight inches wide. The stream here suddenly changes
its character. Hitherto, though swift, it had been deep and
smooth, and confined by steep banks. Now it rushed and rippled
over a pebbly, sandy, or rocky bed, occasionally forming
miniature cascades and rapids, and throwing up on one side or the
other broad banks of finely coloured pebbles. No paddling could
make way here, but the Dyaks with bamboo poles propelled us along
with great dexterity and swiftness, never losing their balance in
such a narrow and unsteady vessel, though standing up and
exerting all their force. It was a brilliant day, and the
cheerful exertions of the men, the rushing of the sparkling
waters, with the bright and varied foliage, which from either
bank stretched over our heads, produced an exhilarating sensation
which recalled my canoe voyages on the grander waters of South
America.
