Should the speed of the pursuers become dangerous, a sharp turn or change in the course would throw them off and give the fugitives an advantage that would last for a long time.

But they dreaded the appearance of a whole pack of the brutes in front, thus shutting off their line of flight homeward.
True, in that case they could turn about and flee up stream, but the risk of encountering others attracted by the cries would be great, and perhaps leave their only recourse to a flight into the woods.
The thoughts of each turned to the nearest hunter's cabin, although it was several miles distant, and probably beyond reach.
It was strange that, having emitted so many signals, the wolves should become suddenly quiescent.
No one spoke, but as they glided swiftly forward they peered along the gleaming surface in search of that which they dreaded to see.
They approached one of those long, sweeping bends to which allusion has been made.

Jennie had already proven that neither of her companions could outspeed her.

They were doing their utmost, but she easily held her own with less effort than they showed.
In truth, she was slightly in advance as they began following the curve of the river, her head, like each of the others, bent forward, to see whither they were going.
"They are there!" It was she who uttered the exclamation which sent a thrill through both.

They asked for no explanation, for none was needed, and an instant later they were at her side, she slightly slackening her pace.

Three or four gaunt animals were trotting along the ice near the left shore, but no others were visible.
"Keep in the middle while I take a turn that way," said Monteith, sheering in the direction named.
Brother and sister did not read the meaning of this course, nor could they detect its wisdom.
