Much circumspection is needed.

He will certainly charge you if you get too near, and on a tired horse he would have the advantage.

So you must e'en halt and wait--not get down, that would be fatal--wait five minutes it may be, ten minutes, or a quarter of an hour, till the gentleman cools off a bit.

Then you start him off again, not so much driving him now, he won't be driven, but guiding his course towards the herd.

In this case we succeeded beautifully, though at the end he had to be raced once more.
