Still the great beast stood immovable, a little pool of blood growing upon the snow under his forward legs.

What was the mystery that lurked in the blackness of yonder forest?
Was it danger?
The keenest of human hearing would have detected nothing.

Yet to those long slender ears of the bull moose, slanting beyond the heavy plates of his horns, there came a sound.

The animal lifted his head still higher to the sky, sniffed to the east, to the west, and back to the shadows of the tamaracks.

But it was the north that held him.
From beyond that barrier of spruce there soon came a sound that man might have heard--neither the beginning nor the end of a wail, but something like it.
