stones were loosened in the wall just above, and a couple of crowbars
were left there ready to lower these still further, so that they would
slip down into the narrow opening left in case of emergency, and thus
completely keep the Indians out.

All these matters took a great deal of time, but the knowledge of the
danger from the prowling bands of Indians always on the war-path on the
plains, and also that of the large treasure in silver that was within
their reach, made the men work like slaves.

Water had been found in a spring right at the top of the mountain, and
after contriving a basin in the rock that it should fill, it was
provided with an outlet, and literally led along a channel of silver
down to where it could trickle along a rift, and then down by the side
of the sloping paths to a rock basin dug and blasted out close to the
entrance in the plain.

This was a good arrangement, for the water was deliciously pure, and
gave an ample supply to the camp, and even to the cattle when necessary,
a second overflow carrying the fount within the corral, where a
drinking-place was made, so that they were thus independent of the lake
upon the plain, or the necessity for contriving a way down to the river
in the canyon. Attention had then to be given to the food supply, and
this matter was mentioned to the Beaver.

For Bart had suggested that no doubt the Indians would find buffalo for
them, instead of passing their time playing the part of mountain scouts
and herdsmen when the cattle were driven to feed down in the rich
pastures by the lake.

CHAPTER TWENTY THREE.

OFF ON A HUNT.

The Beaver did not often smile, but when Bart tried to explain his
wishes to him that he should lead a little party out into the plains to
shoot buffalo for the party, his stolid, warlike countenance began
slowly to expand; there was a twinkle here and a crease there; his
solemn, watchful eyes sparkled; then they flashed, and at last a look of
joy overspread his countenance, and he said a few words eagerly to the
interpreter.

"The Beaver-with-Sharp-Teeth," began the latter slowly, "says that it is
good, and that we will go and hunt bison, for it is men's work, while
minding the grazing cattle here is only fit for squaws."

The Indians immediately began their preparations, which were marked by
their brevity. Rifles and ammunition were examined, girths were
tightened, and small portions of dried meat tied to the pad saddles
re
