The midnight sun had set, but in a crotch between two snow-peaks it had kindled a vast caldron from which rose a mist of jewels, garnet and turquoise, topaz and amethyst and opal, all swimming in a sea of molten gold. The glow of it still clung to the face of the broad Yukon, as a flush does to the soft, wrinkled cheek of a girl just roused from deep sleep. Except for a faint murkiness in the air it was still day. There was light enough for the four men playing pinochle on the upper deck, though the women of their party, gossiping in chairs grouped near at hand, had at last put aside their embroidery.

If she were not reading, her attitude suggested it was less because of the dusk than that she had surrendered herself to the spell of the mysterious beauty which for this hour at least had transfigured the North to a land all light and atmosphere and color. Gordon Elliot had taken the boat at Pierre's Portage, fifty miles farther down the river.
