He knocked out his pipe and pulled his blanket around him, for down in that deep, watered valley the nights were cold. Casey followed his example. In two minutes both men were asleep, with the rush of the water and the crunch-crunch of the horses' teeth cropping the grasses in their ears.

They breakfasted in the dawn, saddled, and took a course downstream, The trail petered out; the hoof marks vanished. They rode with care through thick brush, and more easily in open, parklike glades. Grouse rose almost under their horses' hoofs, to sit bright-eyed on adjacent limbs, watching the travellers. Occasionally deer by twos and threes bounded springily away, white flags waving. Once the horses snorted and showed a disinclination to proceed, sniffing the air nervously.

"Bear," said Casey.

"Down among them berry bushes, I reckon," said the sheriff.

As he spoke, a black, furry head, short ears, and sharp muzzle rose above the tangled bushes. A narrow, red tongue licked out. Cunning little eyes regarded them with indignant suspicion.

"Woof!" said the bear. The sound was something between the snort of a hog and the first interrogative note of a watchdog, which hears a noise that requires explanation.

"Well, sport," said the sheriff, "berryin' good this mornin'?"

But at the sound of the human voice the black head disappeared beneath the surface of foliage. There was a momentary swaying of bushes in one spot, like the swirl of disturbed water after a fish; but there was nothing to mark the line of the beast's flight. For all his bulk he melted through the tangle as soundlessly as a spirit.

"Bears is learnin' manners nowadays," the sheriff commented. "Course, these here black ones never was much different from pigs. But take grizzlies. When I come West with my old people, a little shaver just able to set a pony, they was plumb sassy. I never did see such biggotty-actin' critters. Britch-loaders hadn't been in so durn long, and men didn't go huntin' grizzlies with the little old pea rifle just for fun. They was range bosses, and they knowed it. Now it's only once in a while you'll find one that wants all the trail."

In the afternoon they came to an abandoned cabin, and dismounted to investigate. Casey shook his head at the filthy litter. "Nobody's been here," said he.
