re rapidly, after the first ten shots;
but they counted on being able to hold out against a pretty strong force
of savages, armed as they were.

The wagon went forward slowly, and was kept as much as possible within
the sheltering range of the underbrush. All were in the vehicle, as its
height gave them a better view, and in case of a surprise all would be
guarded and safe.

It was somewhat of a relief to note that directly ahead of them was a
small stream, one of the tributaries of the West, and before reaching
the open area near the river, the Professor directed the wagon toward a
clump of brush, behind which the yaks were tethered.

They were thus in a position where they had an ample water supply, and
the Professor remarked, that in campaigning two things were essential,
one was food and the other water, and of the two water was of most value
for a short period, at least. The yaks needed it, and as that was their
means of transportation, every consideration must be given them.

"As we are now campaigning in earnest, we must have some system, and a
thorough understanding of what is to be done," said the Professor. "A
thorough watch must be kept at all times day and night. We must not
separate, but keep closely together, and in watching just as much care
must be taken of our rear and our flanks. We do not know from which
direction these people are likely to spring up. Remember, from our
experiences night before last, this is territory over which they
travel."

It should be stated that in the night referred to a band of the savages
had passed their camp, going in the direction in which the wagon had
taken, and they were of the impression that those discovered to the
south of the stream were the ones who had come so near finding them.

"There is also another matter that should be considered. While we do not
anticipate any disaster to our party, still we should at all times make
provision for any separation, should such a thing take place. I estimate
that we are now directly south of the mouth of West River, and that the
sea to the north is from fifteen to twenty miles away. Now, let it be
understood that in case we are defeated, or by any chance there should
be any separation, the place of retreat will be toward the location of
the wrecked boat, which is near the mouth of the river."

The great difficulty was to impart this to John. He was interested, in a
peculiar sort of way, in the proceedings, and the Profess
