"Oh, the villain!" spluttered Rosy Delaney, who received the first installment of dirt full in her eyes and mouth. "Moike Delaney, ye made him do that a-purpose!" and she shook her fist at her husband. "Ye bould, bad mon!"

"Oi did not," he ejaculated. "Git back there, ye baste!" he added, and tried to hit Billy with his whip. The knowing mule dodged and, turning swiftly, planted a hoof in Mike's stomach so slickly that the Irishman went heels over head into a nearby puddle.

A shout arose from those standing near.

"Score one round for the mule!"

"Mike, thet summersault war good enough fer a show. Better jine the circus!"

"Oi'll show the mule!" yelled Mike, and rushed in again. But once more Billy turned and got out of the way, and this time he caught the seat of Mike's trousers between his teeth and lifted the frightened man six feet from the ground.

"Don't! Let me down! Somebody save me!" yelled the terrorized son of Erin. "Rosy! Clemmer! Rasco! Hit him! Shoot him! Make him let go av me! Oi'll be kilt entoirely!"

Outsiders were too much amused to help Mike, but Rosy came to the rescue with a woman's best weapon—a rolling-pin, one she occasionally used in making pies for the family when in camp. Whizz! came the rolling-pin through the air, hitting Billy on the ear. The mule gave a short snort, broke what remained of the harness and scampered off to make a complete circuit of the camp and then fall into his regular place near Jack Rasco's turn-out.

"Want him some more?" asked Jack, who had seen the fun, and was compelled to laugh, in spite of his worry.

"Want him some more, is it?" growled Mike. "Not fer a thousand dollars, Rasco! Yez kin kape the mule, an' be hanged to yez!" and he stalked off to borrow a horse that was warranted to be gentle under the most trying of circumstances.
