(The rattlesnake swarms among some of the stony mountains of the North Jersey hinterland; though seldom, nowadays, does it venture into the valleys. But the copperhead--twin brother in murder to the rattler--still infests meadow and lakeside. Smaller, fatter, deadlier than the diamond-back, it gives none of the warning which redeems the latter from complete abhorrence. It is a creature as evil as its own aspect--and name. Copperhead and rattlesnake are the only pit-vipers left now between Canada and Virginia.) Out from its wall-cranny oozed the reptile. Along the fringe of the rug it moved for a foot or two; then paused uncertain--perhaps momentarily dazzled by the light. It stopped within a yard of the child's wizened little hand that rested idle on the rug. Baby's other arm was around Lad, and her body was between him and the snake. Lad, with a shiver, freed himself from the frail embrace and got nervously to his feet. There are two things--and perhaps _only_ two things--of which the best type of thoroughbred collie is abjectly afraid and from which he will run for his life. One is a mad dog. The other is a poisonous snake. Instinct, and the horror of death, warn him violently away from both. At stronger scent, and then at sight of the copperhead, Lad's stout heart failed him. Gallantly had he attacked human marauders who had invaded The Place. More than once, in dashing fearlessness, he had fought with dogs larger than himself. With a d'Artagnan-like gaiety of zest, he had tackled and deflected a bull that had charged head down at the Mistress. Commonly speaking, he knew no fear. Yet now he was afraid; tremulously, quakingly, _sickly_ afraid. Afraid of the deadly thing that was halting within three feet of him, with only the Baby's fragile body as a barrier between. Left to himself, he would have taken, incontinently, to his heels. With the lower animal's instinctive appeal to a human in moments of danger, he even pressed closer to the helpless child at his side, as if seeking the protection of her humanness. A great wave of cowardice shook the dog from foot to head. The Master had alighted from the car; and was coming down the hill, toward his guest, with several letters in his hand. Lad cast a yearning look at him. But the Master, he knew, was too far away to be summoned in time by even the most imperious bark. And it was then that the child's straying gaze fell on the snake. With a gasp and a shudder, Baby shrank back against Lad. At least, the upper half of her body moved away from the peril. Her legs and feet lay inert. The motion jerked the rug's fringe an inch or two, disturbing the copperhead. The snake coiled, and drew back its three-cornered head, the forklike maroon tongue playing fitfully.
