TOM and Fred Kinney were driving back from the little mountain village, where they had been sent from the lumber station, up in the “Slash” on Mount Horrid, to buy supplies for the camp. They took this trip every week, their father, overseer of the camp, trusting them to drive Ted and Tot, the mule team, down the mountain alone.

Mount Horrid, rightly named, is a wild spot, and the mountain roads leading up to the camp are steep and rough. One drives over this trail for about fourteen miles, then arrives at a plateau, and just above, on the ridge, are the lumbermen’s shacks.

Darkness comes very early in these northern mountain regions, for the sun sets beyond the taller mountain crags at a little after four in the afternoon and it is twilight almost before one is aware of it. Suddenly the sides of the mountains take on a deeper purple hue, then in the dense forests of balsam and spruce the shadows grow black and blacker, and already night has come down in the valleys between the ridges.

The night bade fair to be very dark and early, but the boys were not afraid, for the two small mules knew the road well without guidance. They let the lines fall slack across their rough coats, while they munched sweet crackers, and talked together about the best places to set their new muskrat traps, which they had purchased in the village.

The mules crawled leisurely up the steep road, stopping, as they usually did, at a steep pitch to get breath, then plodding on again. All of a sudden, without warning, they began to act very strangely, rearing and plunging about in the strangest fashion, and snorting with fear.

“Say, they act funny, don’t they? Wonder what scared ’em,” remarked Tom, clutching the reins which had almost slipped from his grasp.

“Gee,” replied Fred, “do you know it’s gettin’ awful dark; wish we were back in camp. We ought to have started back sooner, not stayed to see that ball game,” he grumbled. For, to tell the truth, Fred Kinney was the more timid and cowardly of the two.

“Oh, don’t be a fraid-cat, Fred. It wasn’t anything much that scared the mules; perhaps a fox or even a porcupine crossed the road ahead of ’em, that’s all,” commented Tom, easily. “Look, it’s going to be moonlight the rest of the way. Who’s afraid? I ain’t. Have another cracker.”

The mules steadied down to their usual gait once more, and the boys shortly forgot their fears and were soon chatting away about their snares once again.

But if they had only known, and could have peered through a thick fringe of spruces, right on the very edge of a long, rocky ledge, just above the mountain road, crouched a great, tawny, supple, fur-clad cat; the very largest catamount, or, as it is sometimes called, the American panther, which had ever been seen in those parts. The catamount had started out to forage as soon as the first, long purple shadows began to climb the mountains. He was a magnificent specimen of the cat family, a male, and back in his dark den, which he had made beneath an almost inaccessible ledge of rocks, high up in the wildest part of the mountain, he had left a fierce, tawny mate and three kitten cubs.
