I had heard this on waking in the morning, but at the time I had imagined it to proceed from distant thunder.

By ten o'clock the current had so increased as we proceeded that it was distinctly perceptible, although weak.

The roar of the waterfall was extremely loud, and after sharp pulling for a couple of hours, during which time the stream increased, we arrived at a few deserted fishing-huts, at a point where the river made a slight turn.
I never saw such an extraordinary show of crocodiles as were exposed on every sandbank on the sides of the river.

They lay like logs of timber close together, and upon one bank we counted twenty-seven of large size.
Every basking place was crowded in a similar manner.

From the time we had fairly entered the river it had been confined by heights somewhat precipitous on either side, rising to about 180 feet.
