He guided them on horseback up one of the thick, verdant-wooded slopes, calling their attention at various times to the different growths, until they emerged on the summit of the ridge where the timber grew scant and dwarfed. At the edge of timber-line he showed a gnarled and knotted spruce-tree, twisted out of all semblance to a beautiful spruce, bent and storm-blasted, with almost bare branches, all reaching one' way. The tree was a specter. It stood alone. It had little green upon it. There seemed something tragic about its contortions. But it was alive and strong. It had no rivals to take sun or moisture. Its enemies were the snow and wind and cold of the heights. Helen felt, as the realization came to her, the knowledge Dale wished to impart, that it was as sad as wonderful, and as mysterious as it was inspiring. At that moment there were both the sting and sweetness of life--the pain and the joy--in Helen's heart. These strange facts were going to teach her--to transform her. And even if they hurt, she welcomed them. CHAPTER XI “I'll ride you if it breaks--my neck!” panted Bo, passionately, shaking her gloved fist at the gray pony. Dale stood near with a broad smile on his face. Helen was within earshot, watching from the edge of the park, and she felt so fascinated and frightened that she could not call out for Bo to stop. The little gray mustang was a beauty, clean-limbed and racy, with long black mane and tail, and a fine, spirited head. There was a blanket strapped on his back, but no saddle. Bo held the short halter that had been fastened in a hackamore knot round his nose. She wore no coat; her blouse was covered with grass and seeds, and it was open at the neck; her hair hung loose and disheveled; one side of her face bore a stain of grass and dirt and a suspicion of blood; the other was red and white; her eyes blazed; beads of sweat stood out on her brow and wet places shone on her cheeks. As she began to strain on the halter, pulling herself closer to the fiery pony, the outline of her slender shape stood out lithe and strong.
