But nowhere a sign of the vanished guide--still, doubtless, flying at
frantic speed through the frozen woods. There was not even the sound of
disappearing footsteps, nor the echoes of the dying voice. He had
gone--utterly.

There was nothing; nothing but the sense of his recent presence, so
strongly left behind about the camp; _and_--this penetrating,
all-pervading odor.

And even this was now rapidly disappearing in its turn. In spite of his
exceeding mental perturbation, Simpson struggled hard to detect its
nature, and define it, but the ascertaining of an elusive scent, not
recognized subconsciously and at once, is a very subtle operation of
the mind. And he failed. It was gone before he could properly seize or
name it. Approximate description, even, seems to have been difficult,
for it was unlike any smell he knew. Acrid rather, not unlike the odor
of a lion, he thinks, yet softer and not wholly unpleasing, with
something almost sweet in it that reminded him of the scent of decaying
garden leaves, earth, and the myriad, nameless perfumes that make up the
odor of a big forest. Yet the "odor of lions" is the phrase with which
he usually sums it all up.

Then--it was wholly gone, and he found himself standing by the ashes of
the fire in a state of amazement and stupid terror that left him the
helpless prey of anything that chose to happen. Had a muskrat poked its
pointed muzzle over a rock, or a squirrel scuttled in that instant down
the bark of a tree, he would most likely have collapsed without more ado
and fainted. For he felt about the whole affair the touch somewhere of a
great Outer Horror ... and his scattered powers had not as yet had time
to collect themselves into a definite attitude of fighting self-control.
