firm Melton's supposition.
Unfortunately the fact that this Galla warrior was also making the
cruise of the river had been overlooked, and now, as a result of this
negligence they had lost a canoe and half of their supplies.

"We have one thing to be thankful for," said Guy. "If Sir Arthur had not
wakened when he did we would undoubtedly have lost all. His shout scared
the rascal, and he did not wait to make off with the other canoe."

"Yes, here is the mark of a third boat," announced the colonel, who had
been making an investigation on his own account, "and footprints are
visible on the sand. The scoundrel must have been here when we landed."

"I wanted you to make a search," said Sir Arthur, "but my advice was
disregarded. You see the result."

"Prepare to start at once," interrupted Guy sharply. "We must pursue the
thief and recover our canoe."

In less than five minutes they embarked and pushed away from the shore.

"Put out the torch," said Guy. "If the rascal sees the light he can get
out of our way and we will pass him unperceived."

"But how will we capture him in the dark?" asked Melton.

"We must depend on our hearing," was the reply. "We will push ahead
quietly and listen at intervals for the stroke of his paddle."

Under these circumstances the recovery of the canoe was very doubtful,
but there was plainly no other course, so they proceeded to carry out
Guy's plan as carefully as possible.

Five paddles were all that remained, one for each of them, and with
quick, noiseless strokes they moved rapidly down the river, keeping the
canoe headed with the current as far as possible, and pausing at times
to listen for any trace of the thief.

Thus they journeyed for an hour or more, but no sound of any kind
reached their ears, and it began to look very much as though the Galla
had been passed unseen in the darkness.

"He could hardly have kept ahead of us for such a distance," said
Forbes. "I'm afraid we have missed him, Chutney."

Guy made no reply. The canoe at that instant grated harshly on some
obstacle, and throwing out his arms, Melton discovered that the current
had carried them against one of the steep, rocky shores. He was about to
shove the canoe forcibly away with his paddle when Guy whispered
sharply:

"Hold tight to the rock. I hear something above us."

THE JOURNEY ON THE LAKE.

In the deep silence all heard distinctly the low, steady dip of a
paddle.
