“Just come on!” said Wild Bill, speaking to them, but in a low tone.

The other two dogs dashed at the barricade. One rolled down hill, killed by Buffalo Bill’s bullet. The other, frightened by that, retreated, and dashed back up the trail, barking in a startled manner.

The horsemen dismounted, and began to confer.

There were six of them, but soon more appeared; and then it became evident that still others were advancing, along another trail that centered at this point.

The horsemen did not hesitate and confer long. They took their horses back out of sight, and disappeared themselves.

“They are gone!” said the girl.

“And will come back again,” said Wild Bill.

In a little while a rifle spouted from out of the near-by hills, and the leaden missile whistled past the girl’s head and struck the rock behind her.

“Down!” said Buffalo Bill.

Another rifle flamed from another hill, and the lead came into the hollow. The sharpshooters were beginning their work.
