flected on both sides the glow of the torch which
Sir Arthur carried in the stern.

Half a dozen times they dashed through brawling rapids, but no mishap
occurred, and, as their increasing drowsiness warned them that night was
close at hand, they succeeded in finding a landing-place on the left
shore which offered some protection until morning.

A small quantity of wood still remained, and with this a fire was kept
burning all night, while they took turns at guarding the camp, for after
the recent events they no longer dared to sleep unprotected and in utter
darkness.

The scant amount of food now remaining was a source of great uneasiness,
but Chutney infused fresh hope into the party by the confident
prediction that if the present daily rate of speed were maintained the
supply would last until the end of the journey.

Already the pure air of the cavern had done wonders for Sir Arthur and
the colonel, and they had nearly recovered their usual health and
strength. The one canoe held them all very comfortably, and they seemed
to make better progress than when they had been divided into separate
parties.

That night nothing occurred to cause any alarm, and they resumed the
cruise in fairly good spirits. The river still continued narrow and the
current swift. No dangerous water was encountered, and everything was
going on satisfactorily when Guy suddenly shouted with all his might,
"Back water! Quick! quick!" and looking ahead they saw a steep rocky
promontory, against which the current split and swung off into two
channels, one to the right, the other to the left.

In spite of their utmost efforts they continued to float down inch by
inch.

Which was the proper channel? It was a puzzling problem on which perhaps
hung life and death. There was no time for consideration, and under the
circumstances Guy adopted the only possible course.

"Head the canoe straight for the center of the rock and let her drift,"
he cried. "The current shall decide for us."

This was instantly done and they drifted with perfect accuracy straight
for the splitting point in the stream.

For a moment it looked as though they would be flung against the rocks
and upset, but as the canoe reached the turning-point it trembled an
instant in the balance and then darted headlong into the channel to the
right.

"A good omen," cried the colonel. "The river Juba lies on our right.
This must be the proper channel."

It was a very narrow channel
