old man Dumble, "it's this way. There's a big dealer comes
three times a year to Bakersfield; he pays good money for good stuff--
an' he asks no questions. I happened to hear he was a-comin' down only
las' Sunday."

Something in his voice, some sly gleam in his eye, aroused my
suspicions. As soon as we happened to be alone, I whispered to my
brother: "I say, what if the old man is playing hare and hound with
us?"

"Pooh!" said Ajax. "He's keen as mustard to collar this thief--the
keener, possibly, since he discovered that the fellow is a tenderfoot.
I've sized him up about right. He wants to establish a record. It's
like this teetotal business of his. The people here refuse to believe
evil of a man who drinks water, goes to church, and catches horse-
thieves. I'll add one word more. To give the old fraud his due, he
really holds in abhorrence any crime that might land him in the State
penitentiary. Hullo! There's a faint reek out yonder. I'll take a

We called a halt. We were now on the alkaline plains beyond the San
Emigdio mountains. Riding all through the night, we had changed horses
at a ranch where we were known. Ajax stared through his binoculars.

"What we're after," said he quietly, "is in sight."

He handed his glasses to me. I could barely make out a horseman,
herding along two animals. The plains were blazing with heat. In the
distance a soft blue haze obscured the horizon; faintly outlined
against this were three spirals of what seemed to be white smoke:
three moving pillars of alkaline dust.

"He can't git away from us," said old man Dumble.

Looking at him, my suspicions took flight. He was, as Ajax said,
keener than we to arrest the thief. His small eyes sparkled with
excitement; his right index-finger was crooked, as if itching for the
trigger; his lips moved. In fancy he was rehearsing the "Stand and
deliver" of an officer of the law!

"We kin ride him down," he muttered.

"Yes," said Ajax.

We looked to our girths and our pistols. It was unlikely that the
thief would show fight, but--he might. Then we mounted, and galloped
ahead.

"Forrard--for-r-rard!" shouted Ajax.

Within a few minutes, a quarter of an hour at most, the man we were
hunting would see us; then the chase would really begin. He would
abandon the footsore colts, and make for the hills. And so it came to
pass. Presently, we saw the horseman turn off at right angles; the
jaded colts hesitated, t
