showed him the heavy bowie knife so carefully hidden in
its sheath sewn to the inside of his shirt collar.

"With this through his throat, he fell right in the grave they'd dug
fo' me. Then I saw the shovel, and I couldn't resist throwin' some
dirt ovah him. Well, that's that. I hated to take his life, but I had
to do it to save mine. The thing to do now is to get out of this."

"How do yuh expect yore hoss to get to us?" breathed Robbins.

"Listen." The Texan smiled. "He knows this call."

He waited for a lull in the rifle-popping below, and then he gave the
coyote yell--a mournful cry that seemed to echo and reecho. The sound
was so perfect an imitation that Robbins could scarcely believe his
ears. And it even fooled the Indians. It did not, however, deceive
the sagacious horse that waited patiently in the adobe. The Kid
clutched his young companion's arm. Straining their eyes, they saw a
white something moving up an arroyo.

"That Blizzahd hoss is smahter than I am," chuckled the Texan. "He

Watch him climb that dry wash."

They held their breath until Blizzard, moving so noiselessly that his

Then Kid Wolf led him over it and down again into a gully a little

could make it. The Texan mounted and swung up Robbins behind the
saddle.

"Too bad we had to leave that twenty thousand, Kid," said Robbins.

The Kid's white teeth flashed in a smile.

"Really, Dave," he drawled, "do yo' think I'd let Garvey get away with

while the rest of yo' were tippin' back the stagecoach? No? Well, I
transferred the twenty thousand to Blizzahd's saddlebags, so the
money"--he tapped the bulges on each side of the big saddle--"is right
heah!"

Kid Wolf, ever since he had taken charge of the express money, had
realized his responsibility and trust. He would protect it with his
life. If he could reach Mexican Tanks with it, the money would be
safe, for a small post of soldiers and government scouts guarded the
place.

They had not gone a half mile, however, when a sound of distant
shouting broke out behind them.

"That means they've discovahed ouah absence," said the Texan, grimly.
"We'll have ouah hands full befo' long!"

Robbins, and the
