Frona steered straight across the current, at almost right angles, for Split-up; but when the sandspit, over which they had portaged, crashed at the impact of a million tons, Corliss glanced at her anxiously. She smiled and shook her head, at the same time slacking off the course.

"We can't make it," she whispered, looking back at the ice a couple of hundred feet away. "Our only chance is to run before it and work in slowly."

She cherished every inward inch jealously, holding the canoe up as sharply as she dared and at the same time maintaining a constant distance ahead of the ice-rim.

"I canna stand the pace," Tommy whimpered once; but the silence of
Corliss and Frona seemed ominous, and he kept his paddle going.

At the very fore of the ice was a floe five or six feet thick and a couple of acres in extent. Reaching out in advance of the pack, it clove through the water till on either side there formed a bore like that of a quick flood-tide in an inland passage. Tommy caught sight of it, and would have collapsed had not Corliss prodded him, between strokes, with the point of his paddle.

"We can keep ahead," Frona panted; "but we must get time to make the landing?"

"When the chance comes, drive her in, bow on," Corliss counselled; "and when she strikes, jump and run for it."

"Climb, rather. I'm glad my skirt is short."

Repulsed by the bluffs of the left bank, the ice was forced towards the right. The big floe, in advance, drove in upon the precise point of Split-up Island.

"If you look back, I'll brain you with the paddle," Corliss threatened.
