Ruth and Alice were fast becoming adepts in the saddle. The other members of the company, too, soon felt more at home on the back of a horse, and Mr. Pertell allowed them to rehearse in the scenes where mounted action was necessary.

Mr. Bunn had one rather unlucky experience on a horse, and for some time after that he refused to mount a steed, even going to the length of threatening to resign if compelled to.

The "old school" actor was rather supercilious in his manner, and this was resented by some of the cowboys, who thought him "stuck up." They therefore planned a little joke on him. At least, it was a joke to them.

The horse Mr. Bunn had learned to ride was a steady-going beast that had outlived its frisky days, and plodded along just the pace that suited the actor. But there was, among the ranch animals, a "bucking bronco," who looked so much like Mr. Bunn's horse that even some of the cowboys had difficulty in telling them apart.

A bucking bronco, it might be explained, is a steed who by nature or training uses every means in its power to unseat its rider. The bucking consists in the horse leaping into the air, with all four feet off the ground, and coming down stiff-legged, jarring to a considerable degree the person in the saddle.

One day, just for a "joke," the bucking bronco was brought out for Mr. Bunn to ride, when a certain film was to be made. He did not notice that it was not his regular mount. The bronco was quiet and tractable enough until Mr. Bunn settled himself in the saddle, and then, just as Russ was about to make the film, the pony set off at a fast pace.

"Whoa, there! Whoa!" cried Mr. Bunn, trying to halt the beast, and not understanding what could have gotten into his usually quiet mount. "Whoa, there!"

"Give him a touch of the spur," called the mischievous cowboy.

Mr. Pertell did not know what to make of the actions of his actor, for the play called for nothing like that.

"Shall I get that?" asked Russ, and before the manager could answer the bronco began running around in a circle.
