The horse sniffed suspiciously at the dry grass, but did not crop at it.

“Ain’t much juice left in that kinda feed,” declared Skeeter Bill, removing his sombrero and wiping his brow with the sleeve of his shirt. For a few minutes he surveyed the country before riding on.

Suddenly he drew rein and sniffed at the breeze. His rather long nose quivered, and he shook his head. Beyond him a cloud of dust floated over the skyline of a ridge, growing more dense. It was impossible to see what was making the dust-cloud, but whatever it was, it came over the ridge toward Skeeter Bill and dipped down into the depression beyond.

“Sheep!” snorted Skeeter Bill with the true cowman’s disgust of such animals. “We shore poked into one fine country t’ poke right out of ag’in, bronc.”

Skeeter Bill turned and rode angling along the side of the hill, going through a heavy thicket of greasewood. Suddenly his horse jerked ahead and went to its knees, and Skeeter fell head first into a thick clump of brush. As he fell he heard the whip-like snap of a rifle, and he knew that some one had shot his horse from under him.

He backed out of the tangle and investigated. His bay had crashed into some brush farther down the hill, and Skeeter could see that it was dead. He swore softly and held his gun ready.

The bullet had torn through Skeeter’s chaps, along his thigh, missing the flesh by a narrow margin, and had broken the back of the tall bay horse. Skeeter had no idea why he had been shot at, nor how many men might be ready to shoot at him again. It was a ticklish situation, but Skeeter smiled grimly and waited.

Far away he could hear the soft bawling of sheep and the tiny tinkle of a bell. A blue jay screeched harshly from down the cañon. Suddenly the brush crashed as if some one had stumbled into it. Skeeter glanced keenly in that direction, but did not move.

In a few moments the brush crashed again, and Skeeter grinned widely. He knew that some one was tossing rocks into the dry brush to try to get him to investigate. He snuggled a trifle lower and peered low through the tangle of brush above him. Whoever it was, they were moving very cautiously, for no sound of footsteps had come to his ears.

Suddenly his eyes focused on something. It might be part of the brush, and again it might be the legs of a man; a man whose body was completely screened by the heavy foliage. Skeeter considered these leg-like things very closely. Then came a dry cough—more like a wheezing chuckle; as if the man had tried to choke it and merely strangled. It came from above the legs.
