flower.  He heard her laugh, and cry out to Tara, and when the grizzly climbed up a bit of steep slide she leaned forward and became a part of the bear’s back, her curls shimmering in the thick ruff of Tara’s neck.  As he toiled upward in their wake, he caught a glimpse of her looking back at him from the top of the slide, her eyes shining and her lips smiling at him.  She reminded him of something he had read about Leucosia, his favorite of the “Three Sirens,” only in this instance it was a siren of the mountains and not of the sea that was leading him on to an early doom—­if he had to keep up with that bear!  His breath came more quickly.  In ten minutes he was gasping for wind, and in despair he slackened his pace as the bear and his rider disappeared over the crest of the first slope.  She was waving at him then, fully two hundred yards up that infernal hill, and he was sure that she was laughing.  He had almost reached the top when he saw her sitting in the shade of a rock, watching him as he toiled upward.  There was a mischievous seriousness in the blue of her eyes when he reached her side.

“I’m sorry, Sakewawin,” she said, lowering her eyes until they were hidden under the silken sheen of her long lashes, “I couldn’t make Tara go slowly.  He is hungry, and he knows that he is going home.”

“And I thought you had sore feet,” he managed to say.

“I don’t ride him going down a mountain,” she explained, thrusting out her ragged little feet.  “I can’t hang on, and I slip over his head.  You must walk ahead of Tara.  That will hold him back.”

He tried this experiment when they continued their ascent, and Tara followed so uncomfortably close that at times David could feel his warm breath against his hand.  When they reached the second slope the girl walked beside him.  For a half mile it was not a bad climb and there was soft grass underfoot.  After that came the rock and shale, and the air grew steadily colder.  They had started at one o’clock and it was five when they reached the first snow.  It was six when they stood at the summit.  Under them lay the valley of the Firepan, a broad, sun-filled sweep of scattered timber and green plain, and the girl pointed into it, north and west.

“Off there is the Nest,” she said.  “We could almost see it if it weren’t for that big, red mountain.”

She was very tired, though she had ridden Tara at least two thirds of the distance up the mountains.  In her eyes was the mistiness of exhaustion, and as a chill wind swept about them she leaned against David, and he could feel that her endurance was nearly gone.  As they had come up to the snow line he had made her put on the light woollen shirt he carried in his pack; and the big handkerchief, in which he had so long wrapped the picture, he had fastened scarf-like about her head, so she was not cold.  But she looked pathetically childlike and out of place, standing here beside him at the very top of the world, with the valley so far down that the clumps of timber in it were like painted splashes.  It was a half mile down to the first bit of timber—­a small round patch of it in a narrow dip—­and he pointed to it encouragingly.
