, young fellow--what's your name?"

"Jack Roberts," answered the cowboy meekly.

"About this rustler--would you know him again?"

The line-rider smiled inscrutably. He did not intend to tell all that he
did not know. "He was ridin' a sorrel with a white splash on its nose,
white stockin's, an' a bad hoof, the rear one--"

"You're a damn' liar." The words, flung out from some inner compulsion,
as it were, served both as a confession and a challenge.

There was a moment of silence, tense and ominous. This was fighting
talk.

The lank man leaned forward and whispered some remonstrance in the ear
of the young fellow, but his suggestion was waved aside. "I'm runnin'
this, Gurley."

The rider for the A T O showed neither surprise nor anger. He made a
business announcement without stress or accent. "I expect it's you or me
one for a lickin'. Hop to it, Mr. Rustler!"

Roberts did not wait for an acceptance of his invitation. He knew that
the first two rules of battle are to strike first and to strike hard.
His brown fist moved forward as though it had been shot from a gun. The
other man crashed back against the wall and hung there dazed for a
moment. The knuckles of that lean fist had caught him on the chin.

"Give him hell, Ford. You can curry a li'l' shorthorn like this guy with
no trouble a-tall," urged Dinsmore.

The young man needed no urging. He gathered himself together and plunged
forward. Always he had prided himself on being an athlete. He was the
champion boxer of the small town where he had gone to school. Since he
had returned to the West, he had put on flesh and muscle. But he had
dissipated a good deal too, and no man not in the pink of condition had
any right to stand up to tough Jack Roberts.

While the fight lasted, there was rapid action. Roberts hit harder and
cleaner, but the other was the better boxer. He lunged and sidestepped
cleverly, showing good foot-work and a nice judgment of distance. For
several minutes he peppered the line-rider with neat hits. Jack bored in
for more. He drove a straight left home and closed one of his opponent's
eyes. He smashed through the defense of his foe with a power that would
not be denied.

"Keep a-comin', Ford. You shore have got him goin' south," encouraged
Gurley.

But the man he called Ford knew it was not true. His breath was coming
raggedly. His arms were heavy as though weighted with lead. The science
upon which he had prided himself was of no use
