The door flew open with a bang, and Rose and Mike tore in, panting and a-glitter with diamond drops of rain. Instantly the expression of simple guile on the old man's face changed so ludicrously to one of overdone innocence that it was all Donald could do to keep from laughing. "Storm's a-comin'," cried the girl, gayly, while the dog rushed madly around the room, with his nose to the floor and barking hilariously, until his master seized him by the back and held him, squirming. A flash of distant lightning substantiated the announcement, and a few seconds later their ears caught the crescendo reverberations of thunder as it echoed down the valley. Mike growled uneasily and crouched close to his master's legs, but Rose ran again to the door and stood, heedless of the rain which beat in upon her wind-whipped skirt, peering out with evident delight. A still more vivid, zigzag flash rent the serried masses of black storm-clouds which were rolling up over the mountain's top, edging the nearer one with fire, and she laughed merrily and clapped her hands like a child. "Shet thet door, yo' young vixen," bellowed Big Jerry, plainly disturbed. The girl obeyed, and gave him a kiss, and the whining dog a reassuring pat, as she hurried back to finish setting the table--a simple matter, for there was no spotless damask, glittering silver and cut glass to deck the white-scoured top of the plain slab which formed a substantial table for many purposes. In a moment she had announced, quite informally, that supper was served; but, just as the two men arose to take their places, there came a long "hulloo-oo" above the sound of wind and rain. Again Rose dashed to the door, with the cry, "Why, thet's Judd Amos; I knows his call." Without reason or warning Donald experienced a quick tightening about his heart, the absurdity of which caused him to smile. What on earth was it to him if this mountain child's color heightened a shade at a familiar call in a masculine voice? The next instant a tall youth, as lean and sinewy as an Indian, stumbled into the room, with his rough coat about his head, and water streaming from his drenched clothing and the barrel of a gun, which was every whit as modern and efficient as Donald's own. "Gosh a'mighty," he said. "Thought I'd be drownded, shore. Hit's a-goin' ter be a rip-snorter ... worst storm er the summer, by the way hit's started." Then, as he dashed the rain from his eyes, and, for the first time caught sight of the visitor, he stopped short in none too pleased surprise, if the black look which went toward Donald from beneath his lowering brows meant anything. "Make ye acquainted with Donald MacDonald, a doctor man from the city, Judd," boomed the giant's hearty voice. "Doc, shake hands with a neighbor uv ourn, Judd Amos."
