They descended, all but Philip, who grumbled at the cold, wrapped himself in a rug inside the car, and summoned Yerkes to bring him a cup of coffee.

On this height indeed, and beneath the precipices of Mount Macdonald, which rise some five thousand feet perpendicularly above the railway, the air was chill and the clouds had gathered. On the right, ran a line of glacier-laden peaks, calling to their fellows across the pass. The ravine itself, darkly magnificent, made a gulf of shadow out of which rose glacier and snow slope, now veiled and now revealed by scudding cloud. Heavy rain had not long since fallen on the pass; the small stream, winding and looping through the narrow strip of desolate ground which marks the summit, roared in flood through marshy growths of dank weed and stunted shrub; and the noise reverberated from the mountain walls, pressing straight and close on either hand.

"Hark!" cried Elizabeth, standing still, her face and her light dress beaten by the wind.

A sound which was neither thunder nor the voice of the stream rose and swelled and filled the pass. Another followed it. Anderson pointed to the snowy crags of Mount Macdonald, and there, leaping from ledge to ledge, they saw the summer avalanches descend, roaring as they came, till they sank engulfed in a vaporous whirl of snow.

Delaine tried to persuade Elizabeth to return to the car--in vain. He himself returned thither for a warmer coat, and she and Anderson walked on alone.

"The Rockies were fine!--but the Selkirks are superb!"

She smiled at him as she spoke, as though she thanked him personally for the grandeur round them. Her slender form seemed to have grown in stature and in energy. The mountain rain was on her fresh cheek and her hair; a blue veil eddying round her head and face framed the brilliance of her eyes. Those who had known Elizabeth in Europe would hardly have recognised her here. The spirit of earth's wild and virgin places had mingled with her spirit, and as she had grown in sympathy, so also she had grown in beauty. Anderson looked at her from time to time in enchantment, grudging every minute that passed. The temptation strengthened to tell her his trouble. But how, or when?

As he turned to her he saw that she, too, was gazing at him with an anxious, wistful expression, her lips parted as though to speak.

He bent over her.

"What was that?" exclaimed Elizabeth, looking round her.
