He looked up from his cooking and said: "Oh, you're back, Susan," and returned to the pan of buffalo tallow.

This was a strange remissness in the slave and she was piqued. Contrary to precedent it was her father who helped her off. She slid into his arms laughing, trying to kiss him as she slipped down, then standing with her hands on his shoulders told him of her ride. She was very pretty just then, her hair loose on her sunburned brow, her face all love and smiles. But David bent over his fire, did not raise his eyes to the charming tableau, that had its own delightfulness to the two participants, and that one of the participants intended should show him how sweet Susan Gillespie could be when she wanted.

All of which trivial matter combined to the making of momentous matter, momentous in the future for Susan and David. Shaken in her confidence in the subjugation of her slave, Susan agreed to his suggestion to ride to the bluffs after supper and see the plains under the full moon. So salutary had been his momentary neglect of her that she went in a chastened spirit, a tamed and gentle maiden. They had orders not to pass out of sight of the twin fires whose light followed them like the beams of two, watchful, unwinking eyes.

They rode across the bottom to where the bluffs rose, a broken bulwark. That afternoon Susan had found a ravine up which they could pass. She knew it by a dwarfed tree, a landmark in the naked country. The moonlight lay white on the barrier indented with gulfs of darkness, from each of which ran the narrow path of the buffalo. The line of hills, silver-washed and black-caverned, was like a rampart thrown across the entrance to the land of mystery, and they like the pygmy men of fairyland come to gain an entry. It was David who thought of this. It reminded him of Jack and the Beanstalk, where Jack, reaching the top of the vine, found himself in a strange country. Susan did not remember much about Jack. She was engrossed in recognizing the ravine, scanning the darkling hollows for the dwarf tree.

It was a steep, winding cut, the tree, halfway up its length, spreading skeleton arms against a sky clear as a blue diamond. They turned into it and began a scrambling ascent, the horses' hoofs slipping into the gutter that the buffaloes had trodden out. It was black dark in the depths with the moonlight slanting white on the walls.

"We're going now to find the giants," David called over his shoulder. "Doesn't this seem as if it ought to lead us up right in front of Blunderbore's Castle?"

"The buffalo runs are like trenches," she answered. "If you don't look out your horse may fall."

They tied their horses to the tree and climbed on foot to the levels above. On the earth's floor, unbroken by tree or elevation, there was not a shadow. It lay silver frosted in the foreground, darkening as it receded. In the arch above no cloud filmed the clearness, the moon, huge and mottled, dominating the sky. The silence was penetrating; not a breath or sound disturbed it. It was the night of the primitive world, which stirred the savage to a sense of the infinite and made him, from shell or clay or stone, carve out a God.

Without speaking they walked forward to a jutting point and looked down on the river. The current sparkled like a dancer's veil spread on the grass. They could not hear its murmur or see the shifting disturbance of its shallows, only received the larger impression of the flat, gleaming tide split by the black shapes of islands. David pointed to the two sparks of the camp fires.

"See, they're looking after us as if they were alive and knew they mustn't lose sight of us."
