rough jumble I found two of his deserted winter dens to which he never
returned, and once in midwinter I found him out, asleep beneath some
brush over which the snow had drifted. It was the thread of rising
steam from a tiny hole above the den that first attracted my attention
to it, but my nose gave me additional information.

Blackie's tracks showed he had unusually large feet for his pounds, so
I called him "Bigfoot." There was a marked difference between
Blackie's and the other tracks I found in the "bad-lands." The other
tracks were those of a grizzly, a fact I determined after collecting
evidence for several years, and by sight of the animals themselves.
There was a wide difference, too, in the actions of these animals
whenever anything unusual happened. Blackie, commonly, ran away
without waiting to learn what had caused the alarm. The grizzly
displayed extreme caution, usually standing erect on his hind feet,
remaining motionless, watching for silent signals of other animals and
the birds, swinging his head slowly from side to side, training his
high-power nose in all directions, cocking his ears alertly as a
coyote. When he located the enemy he slipped away noiselessly,
followed a trail with which he was familiar and left the vicinity,
perhaps traveling ten or twenty miles before stopping.

Unlike Blackie, too, the grizzly was a prodigious worker. No job was
too big for him. Often he spent an hour or more in digging out a tiny
titbit such as a chipmunk, and several times in his pursuit of a marmot
he excavated in rockslides holes large enough for small basements.
Daily he traveled many miles, foraging for food as he moved, sometimes
eating swarms of grasshoppers, or stowing away bushels of grass or
other greenery, or uprooting the ground for dogtooth violets of which
he was very fond. Such spots, when he had finished his rooting,
resembled a field which the hogs had plowed up.

In one respect the black bear and the grizzly were alike: they never
seemed to have enough to eat, but had the insatiable appetites of
growing boys; never showing any signs of being finicky, but devouring
everything edible. Ants, hoppers, chipmunks, marmots and rabbits,
comprised their fresh meat; while roots, shoots, bulbs, grass, berries
and practically everything growing served for vegetables. They both
were inordinately fond of honey. Early one fall the grizzly left his
home range and headed for the foothills. More t
