he porch was in shadow. He peered in vain for the white form against
the dark background. In the silence he seemed to hear his heart-beats
thick and muffled.

Some distance down the path he heard the sound of hoofs. Withdrawing
into the gloom of a cedar, he watched. Soon he made out moving horses
with riders. They filed past him to the number of half a score. Like
a flash of fire the truth burned him. Mormons come for one of those
mysterious night visits to sealed wives!

Shefford stalked far down the valley, into the lonely silence and the
night shadows under the walls.

VIII. THE HOGAN OF NAS TA BEGA

The home of Nas Ta Bega lay far up the cedared slope, with the craggy
yellow cliffs and the black canyon and the pine-fringed top of Navajo
Mountain behind, and to the fore the vast, rolling descent of cedar
groves and sage flats and sandy washes. No dim, dark range made bold
outline along the horizon; the stretch of gray and purple and green
extended to the blue line of sky.

Down the length of one sage level Shefford saw a long lane where the
brush and the grass had been beaten flat. This, the Navajo said, was a
track where the young braves had raced their mustangs and had striven
for supremacy before the eyes of maidens and the old people of the
tribe.

"Nas Ta Bega, did you ever race here?" asked Shefford.

"I am a chief by birth. But I was stolen from my home, and now I cannot
ride well enough to race the braves of my tribe," the Indian replied,
bitterly.

In another place Joe Lake halted his horse and called Shefford's
attention to a big yellow rock lying along the trail. And then he spoke
in Navajo to the Indian.

"I've heard of this stone--Isende Aha," said Joe, after Nas Ta Bega had
spoken. "Get down, and let's see." Shefford dismounted, but the Indian
kept his seat in the saddle.

Joe placed a big hand on the stone and tried to move it. According to
Shefford's eye measurement the stone was nearly oval, perhaps three feet
high, by a little over two in width. Joe threw off his sombrero, took a
deep breath, and, bending over, clasped the stone in his arms. He was an
exceedingly heavy and powerful man, and it was plain to Shefford that
he meant to lift the stone if that were possible. Joe's broad shoulders
strained, flattened; his arms bulged, his joints cracked, his neck
corded, and his face turned black. By gigantic effort he lifted the
stone and moved it about six inches. Then as he released
