ter leave them on this side."

The raft was launched, and it was pushed out with the poles, but before
going very far it was seen that the idea was impracticable, and it might
be a hazardous operation.

"This won't do. Besides, we may not be able to go into the woods very
far, in any event."

"Then," said Harry, "we must select a good place for the team, where
they will be in reach of water, and cut plenty of feed for the yaks, as
I can see a good half day's sport before us."

"I hope, Harry, we shall not make the mistake of getting lost this time.
Let us keep the sun in mind, and watch our bearings at all times."

"The mountains to the south will always be a guide for us. Don't forget
that. Then, we shall also know the river is to the north, or in the
opposite direction from the mountains."

"So that we may know just where the team is, we must take a note of its
location. See the four large trees near the other bank. I think we can
remember them, and can see them for some distance."

The raft was pushed across the river, and when it had been properly
secured, they began the march directly to the southwest, and within a
half hour reached the border line of the great forest.

"Six months ago I would have dreaded to enter such a dense wood as
this," said George.

"I was thinking of that, too," replied Harry. "Isn't it singular how we
become used to dangers? This is fun now. I can never forget the first
long trip we made through the forest to the west of the Cataract. I was
frightened at every step, and started at the least noise."

As they entered, the underbrush grew thinner, but the trees were more
massive and thicker, and they were so close together, in many places,
that little sunlight found its way through the foliage.

"I would like to know, Harry, how we can tell where the mountains are?
The trees do not give us an opportunity."

"I suppose we shall have to depend on the sun altogether."

"Yes; it is now forenoon, and we must not forget that the shadow will
point in a different direction in six hours from now."

"I have taken note of that," replied Harry. "We are now following our
shadow, see? In six hours, which will be about four o'clock, which
direction must we go to reach the wagon, judging by the shadow?"

"Let me see; the shadow is to the southwest now. At four this afternoon,
it will be about southeast, so, I suppose, we shall have to take a
course with the shadow at our right hand."
