up on his hind legs, resting his fore paws on her hip and at the
same time licking Skiff Miller's hand. When the latter shook hands with
Walt, Wolf repeated his act, resting his weight on Walt and licking both
men's hands.

"It ain't no picnic, I can tell you that," were the Klondiker's last
words, as he turned and went slowly up the trail.

For the distance of twenty feet Wolf watched him go, himself all
eagerness and expectancy, as though waiting for the man to turn and
retrace his steps. Then, with a quick low whine, Wolf sprang after him,
overtook him, caught his hand between his teeth with reluctant
tenderness, and strove gently to make him pause.

Failing in this, Wolf raced back to where Walt Irvine sat, catching his
coat sleeve in his teeth and trying vainly to drag him after the
retreating man.

Wolf's perturbation began to wax. He desired ubiquity. He wanted to be
in two places at the same time, with the old master and the new, and
steadily the distance between them was increasing. He sprang about
excitedly, making short nervous leaps and twists, now toward one, now
toward the other, in painful indecision, not knowing his own mind,
desiring both and unable to choose, uttering quick sharp whines and
beginning to pant.

He sat down abruptly on his haunches, thrusting his nose upward, the
mouth opening and closing with jerking movements, each time opening
wider. These jerking movements were in unison with the recurrent spasms
that attacked the throat, each spasm severer and more intense than the
preceding one. And in accord with jerks and spasms the larynx began to
vibrate, at first silently, accompanied by the rush of air expelled from
the lungs, then sounding a low, deep note, the lowest in the register of
the human ear. All this was the nervous and muscular preliminary to
howling.

But just as the howl was on the verge of bursting from the full throat,
the wide-opened mouth was closed, the paroxysms ceased, and he looked
long and steadily at the retreating man. Suddenly Wolf turned his head,
and over his shoulder just as steadily regarded Walt. The appeal was
unanswered. Not a word nor a sign did the dog receive, no suggestion and
no clew as to what his conduct should be.

A glance ahead to where the old master was nearing the curve of the
trail excited him again. He sprang to his feet with a whine, and then,
struck by a new idea, turned his attention to Madge. Hitherto he had
ignored her, but now, b
