evoured was positive evidence that there were no
other wolves in the neighborhood.

Glancing around, and listening for a moment, he became convinced that
the cave was now tenantless, and so he passed on beyond the first point
that he had before discovered, and began looking for the next.

Holding the diagram in one hand, and a revolver in the other, he was not
long in finding it, and thus two points were gained that corresponded
with it.

Again he consulted and compared.

Ten feet marked on the diagram, and then there was an index finger
pointing east.

He paced the distance as accurately as he could, but by this time he had
entered the cave so far that he could scarcely see about the place.

But he had come prepared for just such an emergency as this, and taking
a candle and match from his game-bag, he proceeded to make a light.

He glanced cautiously around the dark and somber cave, and the first
thing his eyes rested on were the forms of two dead wolf cubs, evidently
belonging to one of the mothers he had slain the week before, and
undoubtedly starved to death in consequence.

But this attracted his attention for only a moment.

Standing at the distance of ten feet from the last-discovered point, he
held up a little compass that he wore as a charm to his watch chain, in
order to ascertain in which direction east lay.

The tiny magnet finally stood still and pointed. The east lay to the
right.

Again, by the aid of his candle, he searched for indications.

The walls were damp and seemingly solid.

Had he lost the lead? With the butt of his pistol he began rapping along
the stone wall.

It seemed like original adamant.

Then he paused, and again consulted the diagram.

He seemed to have followed it correctly.

There were no further marks upon it, and he finally began to fear that
he was on the wrong scent after all.

Again he went to the mouth of the cave, and retraced each point
carefully.

There could be no mistake about it, provided he was in the right place;
and if he was not, it was a strange coincidence that two such peculiar
points should exist in more than one cave.

Once more he approached the side of the cave to which the index finger
pointed, and made a still closer examination of it.

But it was as solid as granite could be, as indicated by sounds.

He was about to give up, with the idea that he was in the wrong cave,
and began slowly to walk towards the opening.

Suddenly he r
