In his darkest hours David thought sometimes to run away. He was miserably alone on the cold bosom of the world. The very fact that he was the son of his father isolated him in the Daleland. Naturally of a reserved disposition, he had no single friend outside Kenmuir. And it was only the thought of his friends there that withheld him. He could not bring himself to part from them; they were all he had in the world. So he worked on at the Grange, miserably, doggedly, taking blows and abuse alike in burning silence. But every evening, when work was ended, he stepped off to his other home beyond the Stony Bottom. And on Sundays and holidays--for of these latter he took, unasking, what he knew to be his due--all day long, from cock-crowing to the going down of the sun, he would pass at Kenmuir. In this one matter the boy was invincibly stubborn. Nothing his father could say or do sufficed to break him of the habit. He endured everything with white-lipped, silent doggedness, and still held on his way. Once past the Stony Bottom, he threw his troubles behind him with a courage that did him honor. Of all the people at Kenmuir two only ever dreamed the whole depth of his unhappiness, and that not through David. James Moore suspected something of it all, for he knew more of M'Adam than did the others. While Owd Bob knew it as did no one else. He could tell it from the touch of the boy's hand on his head; and the story was writ large upon his face for a dog to read. And he would follow the lad about with a compassion in his sad gray eyes greater than words. David might well compare his gray friend at Kenmuir with that other at the Grange. The Tailless Tyke had now grown into an immense dog, heavy of muscle and huge of bone. A great bull head; undershot jaw, square and lengthy and terrible; vicious, yellow-gleaming eyes; cropped ears; and an expression incomparably savage. His coat was a tawny, lion-like yellow, short, harsh, dense; and his back, running up from shoulder to loins, ended abruptly in the knob-like tail. He looked like the devil of a dogs' hell. And his reputation was as bad as his looks. He never attacked unprovoked; but a challenge was never ignored, and he was greedy of insults. Already he had nigh killed Rob Saunderson's collie, Shep; Jem Burton's Monkey fled incontinently at the sound of his approach; while he had even fought a round with that redoubtable trio, the Vexer, Venus, and Van Tromp. Nor, in the matter of war, did he confine himself to his own kind. His huge strength and indomitable courage made him the match of almost anything that moved. Long Kirby once threatened him with a broomstick; the smith never did it again. While in the Border Ram he attacked Big Bell, the Squire's underkeeper, with such murderous fury that it took all the men in the room to pull him off.
