They had not gone far, however, when Von Bloom perceived that one hound was forging ahead of the rest, and running much faster than any of them.

He might have been a swifter dog than the others, but the hunter did not think it was that.

He appeared rather to be running harder than they, as if sent forward to _push_ the hartebeest, while the rest saved their wind.
This proved to be really the case; for the dog, by a desperate effort, having gained upon the antelope, caused the latter to turn slightly from its original course; and the pack, perceiving this, changed their direction at the same time, and held along a diagonal line, as if to head the game.

By this means they avoided the detour which both the antelope and their companion had made.
The hartebeest was now running upon a new line; and as before, one of the hounds was soon seen to head the pack, and press forward at the top of his speed.

The one that first led, as soon as the antelope turned from its original course, fell back, rejoined the pack, and was now lagging among the hindmost! His "turn" of duty was over.
Again the hartebeest verged from its course.
