others smaller.

"There is the place," said Juarez, nodding at the walls in front of us.
They rose up to a height of over a thousand feet. "There we find it."

We walked with our long gliding stride, something as the Indians do,
scarcely raising the foot. (I may as well have a word with you right
here about walking, if you don't mind; it will be of use to you in long
tramps. There is considerable nonsense in certain popular ideas about
walking. Don't strut along with the shoulders thrown back. You will
never see an Indian plainsman, nor any natural walker do that. Let the
shoulders droop naturally, but keep the chest out. As you start, break
the motion at the hips and use the feet as though they were paddles.
Leave the backbone out of your walk. Anything that saves a jar to that
makes for tireless endurance.

In using this simple method the weight falls on the front part of the
foot. Move easily, even loosely, at the joints of ankle and knee. That
breaks up stiffness, relieves strain and makes for endurance. Paddle out
with the feet, and as you start, break the motion at the hip by a slight
bend. By this method you acquire springiness. It is something the same
effect you get as you stand on the end of a springing board ready to
make a dive into water. If you are persistent in using this method, you
will find it worth while.)

"What is that curious formation under the cliff?" asked Tom as we
approached the outer wall.

"That," said Juarez, "is what remains of the houses and caches of the
cliff dwellers."

It was in a great sheltering cave or open cavern in the beautifully
smooth sandstone cliff, several hundred feet from the base of it.

There stood, almost as a natural granite from the rock, the square,
symmetrical ruins of a tiny cliff dwellers' village. There was something
extraordinarily quaint and curious about it as it nestled close under
the protecting breast of the great rock.

At the base of the cliff were the ruins of a lower village. We found
several complete specimens of pottery and many broken shards.

We could see that the construction of the thick walls of the close set
houses was of flat stones held together by dried clay or with nothing
but the rocks themselves pieced together. The windows and doors had
sides and slabs of smooth, red stone.

THE FACE IN THE ROCK

"Will we find the treasure up there?" asked Tom. Juarez shook his head.

"No, but those people could h
