watched
the line of images broken by the small waves in the lake and listened to
the foals which had only tasted the water and now were splashing it
about with their upper lips. For his own part he did not drink too much,
since much water in the belly makes a leaden burden and Alcatraz felt
that, as leader, he must always be ready for running. A scrawny colt,
escaping from the heels of a yearling floundered against him. Alcatraz
gave way to the little fellow and warned the yearling back with a savage
baring of his teeth and a shake of his head. The foal, with head cocked
upon one side, regarded its protector with impish curiosity and was in
the act of nibbling at the flowing mane of the stallion when Alcatraz
heard a sharp humming as of a wasp; then the sound of a blow, and the
foal leaped straight into the air with head flung back. Before it hit
water a report as of a hammer falling on anvil burst across the level
pond, and then the colt struck heavily on its side, dead.

That bullet had been aimed for the tall leader and only the lifting of
the foal's head had saved Alcatraz. He recognized the report of a rifle
and whirled from the water-edge, signalling his company with a short
neigh of fear; the arch enemy was upon them! A volley poured in.
Alcatraz, as he gained the shore, saw an old stallion double up with a
scream of pain and no sound is so terrible as the shriek of a tortured
horse. No sound is so terrible even to horses. It threw the leader into
an hysteria of panic. Others of the herd were falling or staggering in
the lake; the remnant rushed up the slope and over the sheltering crest
of the hill beyond.

Every nerve in the body of Alcatraz urged him to leap away with arrowy
speed, passing even the grey mare--she who now shot off across the hills
far in the van--but behind him raced weaker and slower horses, the older
stallions and the mares with their foals. Instinct proved greater than
fear. He swept around the rear of his diminished company to round up the
laggards, but they were already laboring to the full of their power as
five horsemen streamed across the crest with their rifles carried at the
ready. They were a hardy crew, these cowpunchers of the Jordan ranch,
but to the sternest of them this was ugly work. To draw a bead on a
horse was like gathering the life of a man into the sight of the rifle,
yet they knew that a band of wildrunning mustangs is a perpetual menace.
Already the black leader had r
