done, and turning squarely about he strode up the trail. He had not
taken a dozen paces, when far ahead of him he saw the red glow of a
fire. Then a hand caught his arm, clutching at it almost fiercely, and
he turned to meet the girl's face, white now with a strange terror.

"What is it?" he cried. "Tell me--"

He caught her hands again, startled by the look in her eyes. Quickly she
pulled herself away. A dozen feet behind her, in the thick shadows of
the forest trees, something took shape and movement. In a flash Howland
saw a huge form leap from the gloom and caught the gleam of an uplifted
knife. There was no time for him to leap aside, no time for him to reach
for the revolver which he carried in his pocket. In such a crisis one's
actions are involuntary, machine-like, as if life, hovering by a thread,
preserves itself in its own manner and without thought or reasoning on
the part of the creature it animates.

For an instant Howland neither thought nor reasoned. Had he done so he
would probably have met his mysterious assailant, pitting his naked
fists against the knife. But the very mainspring of his existence--which
is self-preservation--called on him to do otherwise. Before the startled
cry on his lips found utterance he flung himself face downward in the
snow. The move saved him, and as the other stumbled over his body,
pitching headlong into the trail, he snatched forth his revolver. Before
he could fire there came a roar like that of a beast from behind him
and a terrific blow fell on his head. Under the weight of a second
assailant he was crushed to the snow, his pistol slipped from his grasp,
and two great hands choked a despairing cry from his throat. He saw a
face over him, distorted with passion, a huge neck, eyes that named like
angry garnets. He struggled to free his pinioned arms, to wrench off the
death-grip at his throat, but his efforts were like those of a child
against a giant. In a last terrible attempt he drew up his knees inch by
inch under the weight of his enemy; it was his only chance, his only
hope. Even as he felt the fingers about his throat, sinking like hot
iron into his flesh, and the breath slipping from his body, he
remembered this murderous knee-punch taught to him by the rough fighters
of the Inland Seas, and with all the life that remained in him he sent
it crushing into the other's abdomen. It was a moment before he knew
that it had been successful, before the film cleared from
