On the other hand, the wild horse felt that his life, or at least his freedom, depended upon it, and this was enough to urge _him_ to his utmost.

Both flew like the wind--pursuer and pursued.
As they parted from the herd, there was not more than three hundred yards between them; and they must have passed over some miles afterwards, before this distance was greatly lessened.

Their line of flight was as straight as an arrow; and from this it was evident that the mustang usually trusted to his hoofs to save him from his enemies.
In a race like this, however, the pursuer has the advantage of the pursued.

The latter, always anxious, is constrained to look back; and is, therefore, less sure of the ground that lies before.

He loses his proper attitude for speed, and is besides in danger of stumbling.
