time on this lake. We
must seek the outlet at once and resume the journey."

They paddled gladly away from the Isle of Skeletons, as the colonel
insisted on naming it, and steered as straight a course as possible.

Under the pressure of four paddles the canoe maintained a rapid speed,
but in spite of this it was fully an hour, and probably much more,
before they found the shore of the lake. They rested a little while
beside the perpendicular wall of rock, uncertain which way to turn.

"It won't make much difference," said Guy; "either course must bring us
to the outlet. Suppose we try the right."

This proposition met with favor, and off they started once more, taking
care to keep the shore constantly in sight, lest they should lose their
bearings again.

In less than half an hour the sound of running water was heard in the
distance, and they paddled faster than ever in their intense longing to
escape from the lake.

Louder and louder grew the roar of the water, until they seemed to be
almost upon it, and just when they were preparing for a dash into the
rapids Chutney rose in the canoe with a cry of surprise, and the
torchlight showed plainly a fierce body of water running, not out of,
but into the lake.

They had come back to the starting point. It was here they had entered
the lake, and now all must be done over again.

"Back water," cried the colonel. "Don't get into the current. It may
sweep us out and we shall lose our bearings. Turn the canoe and we will
go back the way we came."

There was no help for it. It only remained to atone for the lost time by
paddling as rapidly as possible.

With difficulty the canoe was snatched from the influx of the current
and headed this time to the left.

"It will be a lengthy paddle," said Guy. "The lake is by no means a
small one."

"I'm hungry," exclaimed Sir Arthur. "Isn't it about time for lunch?"

"Your suggestion is eminently proper, Sir Arthur," declared the colonel.
"On a full stomach we shall travel faster, Chauncey. Do you concur with
our views?"

Guy evidently did, for a supply of dates and crackers was forthwith
produced, and while they were eating the canoe was permitted to remain
stationary.

They started away in somewhat better spirits, Chutney in the bow keeping
a sharp watch for danger ahead, while Sir Arthur held his torch from the
stern, lighting the water for some yards around.

The dreary monotony of the journey was most trying. The shor
