e swinging doors of the saloon.

It was a dull time of day for O'Brien, so he sat with his feet on the
edge of the bar and sipped a tall glass of beer; he looked up at the
welcome click of the doors, however, and then was instantly on his feet.
The good red went out of his face and the freckles over his nose stood
out like ink marks.

"There's a black hoss outside," said Jerry, "that I'm going to buy.
Where's the owner?"

"Have a drink," said the bartender, and he forced an amiable smile.

"I got business on my hands, not drinking," said Jerry Strann.

"Lost your chestnut?" queried O'Brien in concern.

"The chestnut was all right until I seen the black. And now he ain't a
hoss at all. Where's the gent I want?"

The bartender had fenced for time as long as possible.

"Over there," he said, and pointed.

It was a slender fellow sitting at a table in a corner of the long
room, his sombrero pushed back on his head. He was playing solitaire and
his back was towards Jerry Strann, who now made a brief survey, hitched
his cartridge belt, and approached the stranger with a grin. The man did
not turn; he continued to lay down his cards with monotonous regularity,
and while he was doing it he said in the gentlest voice that had ever
reached the ear of Jerry Strann: "Better stay where you are, stranger.
My dog don't like you."

And Jerry Strann perceived, under the shadow of the table, a blacker
shadow, huge and formless in the gloom, and two spots of incandescent
green twinkling towards him. He stopped; he even made a step back; and
then he heard a stifled chuckle from the bartender.

If it had not been for that untimely mirth of O'Brien's probably nothing
of what followed would have passed into the history of the Three B's.

CHAPTER VIII

THE GIFT-HORSE

"Your dog is your own dog," remarked Jerry Strann, still to the back of
the card-laying stranger, "but this ain't your back-yard. Keep your eye
on him, or I'll fix him so he won't need watching!"

So saying he made another step forward, and it brought a snarl from the
dog; not one of those high-whining noises, but a deep guttural that
sounded like indrawn breath. The gun of Jerry Strann leaped into his
hand.

"Bart," said the gentle-voiced stranger, "lie down and don't talk." And
he turned in his chair, pulled his hat straight, and looked mildly upon
the gunman. An artist would have made much of that picture, for there
was in this man, as in Strann, a
