"That's right," answered Ben. "What's the matter with chasing them?" He spoke with the authority of the hunter. Possessing the rifle, no opportunity to exploit it was ever allowed to slip; nor, if the truth be told, was John slow in calling attention to his saddle, spurs, and fringed leather chaps.

"All right," said John. "We've never been on an antelope hunt alone."

The boys went off at right angles from the direction they had been taking and rode down a shallow ravine or coulie in order to keep out of sight of the game. They rode slowly along till they reached the end of the depression; here they dismounted and each tied the forelegs of his horse with the rope he carried on his saddle-horn: they were not going to travel afoot again if they could help it. It was now necessary to cross the open prairie in plain view of the animals they sought. Advantage was taken of a well-known characteristic of antelopes—their curiosity. John pulled the handkerchief from his neck and began to wave it slowly to and fro over his head as he walked. Ben followed in his brother's tracks, making himself as inconspicuous as possible and fingering the lock of his repeater to be sure that it was in good working order.

The boys drew nearer and nearer, and the flagging was kept up persistently; but it did not seem to have any effect, for the animals were all looking the other way. Still they drew nearer; their eyes were fixed on their quarry, the rifle held ready, every nerve tense, each heart beating furiously with excitement.

ROPING AN UNBROKEN HORSE.

Then it was seen that the antelopes were attracted by the white tops of the wagons, which were moving slowly along over the plain. The wagon train was "flagging" them. Now if the hunters could get within range before the spell of curiosity had been satisfied, all would be well.

The boys moved cautiously along till they came to a sunken "buffalo wallow," a muddy place frequented by the bison for the sake of the moisture. This afforded the shelter that was needed. Attracted by the flapping canvas wagon-tops, the unsuspecting animals drew slowly near the hiding place.
