ltant cry Billy sprung from his saddle, and quickly formed a
"bow-stall"[1] which, when properly made, is more effective than a
severe curb bit--and placed it upon the animal that was choked beyond
the power of resistance.

[Footnote 1: A "bow-stall" is formed by taking a turn with a rope or
lariat between the nostrils and eyes of a horse, and passing one end
over the head, back of the ears and tied on the opposite side. A second
noose is then made around the jaws and from this the reins lead back
toward the rider, who can then thoroughly manage the animal.--THE

Loosening the lariat around his neck Billy sprung upon the prostrate
animal, which, with a wild snort bounded to his feet, and with
prodigious leaps started on after the flying herd, his daring young
rider firmly seated upon his back.

Finding he could not unseat Billy by bounding, he came to a sudden halt,
and then reared wildly; but with catlike tenacity the boy clung to him,
and then Sable Satan mad with rage and fright, attempted to tear him
from his back with his gleaming teeth.

A severe jerk on the bow-stall however thwarted this, and with a
maddened cry the splendid prairie king bounded on once more after the
flying herd, a call to Little Grey from Billy causing him to follow at
a swift run.

With a speed that was marvelous Sable Satan flew on, directly into the

any danger to keep the animal whose capture had baffled the very best
horsemen of the plains.

Sweeping through the herd, as though they were stationary, so great was
his speed, the black stallion soon left them far behind, and glancing
back Billy saw that Little Grey had not cared to venture into the midst
of the wild band and was galloping away over the prairies.

Not knowing who might pick him up, and having his rifle, ammunition and
provisions strapped to his saddle, he determined to go on after Little
Grey, and at once a fierce fight began between the boy and his horse.

But the boy proved the master, and after a severe struggle the black
stallion was subdued, and guided by the bow-stall was in full chase of
Little Grey, while Sable Satan's former subjects were flying away
northward without their leader.

When in chase of Little Grey, Billy soon discovered the remarkable speed
of his new capture, for he overhauled his former pet with ease, and now
thoroughly broken in, the saddle and bridle were tran
