"Sonny!" he shouted. "Well, I'll be d——d!" And he gripped fervently at the mule's neck.

Reassured at the sound of his master's voice, the big mule took his teeth out of Wright's shoulder and began nuzzling solicitously at his sandy head.

"It's all right, old man," said the New Brunswicker, thinking quickly, while with his left hand he secured a grip on the mule's head-stall. Then he strove to raise himself from the slime. The effort produced no result, except to send a wave of blackness across his brain. Wondering sickly if he carried some terrible injury concealed under the mud, he made haste to pass the halter rope under his arms and knot it beneath his chest. Then he shouted for help, twice and again, till his voice trailed off into a whimper and he relapsed into unconsciousness. The mule shifted his feet to gain a more secure foothold on the treacherous slope, and then stood wagging his ears and gazing down on Jimmy in benevolent content. So long as Jimmy was with him, he felt that things were bound to come all right. Jimmy would presently get up and lead him out of the shell-hole, and take him home.

Shell after shell, whining or thundering according to their breed, soared high over the hole, but the black mule only wagged his ears at them. His eyes were anchored upon the unconscious sandy head of Jimmy Wright. Suddenly, however, a sharp voice made him look up. He saw a couple of stretcher-bearers standing on the edge of the shell-hole, looking down sympathetically upon him and his charge. In a second or two they were beside him, skilfully and tenderly extricating Jimmy's body from the mud.

"He ain't gone west this time," pronounced one, who had thrust an understanding hand into the breast of the tunic.

Jimmy Wright opened his eyes wide suddenly.

"Not by a d——d sight I ain't, Bill!" he muttered, rather thickly. Then, his wits and his voice coming clearer, he added: "But if I ain't, it's thanks to this here old —— of an Argentine mule, that come down into this hole and yanked me out o' the mud, and saved me. Eh, Sonny?"

The big mule was crowding up so close to him as to somewhat incommode the two men in their task on that treacherous incline. But they warded off his inconvenient attentions very gently.

"He's some mule, all right," grunted one of the bearers, as they got Jimmy on to the stretcher and laboriously climbed from the shell-hole.
