"Hold up, thar! Who goes yander?"

Not a word from Merriwell's lips, but he drove the[Pg 75] spurs to the horse, clutched Big Monte tighter, and they shot forward into the valley.

Instantly sounded a shot, followed by several more. Bullets whistled past them. Frank felt Monte give a great start and lurch sideways, but he held the man steady.

There were cries of rage from the men who had fired the shots.

Not a word did Frank speak, but he held straight on toward the head of the valley and Camp Mystery.

As he approached he saw lights gleaming ahead, seeming to indicate that the sound of shooting had come up the valley and aroused the miners.

He was challenged, but gave an answer that caused the men to welcome him with a shout. It was Crowfoot who seized the lather-white horse by the bit, but it was another who caught Big Monte as the ruffian plunged from the saddle on being released from Frank's arms.

"I 'lows he'd got it good an' plenty," said the man who caught Monte. "Ef he ain't dead a'ready, he'll be so right soon."

"Take him inside somewhere," directed Frank. "Every man who can find a weapon wants to get ready to fight. We're going to have a gang of ruffians down on us here, and we'll have to fight to hold this mine."

"We're all ready, Mr. Merriwell," said Jim Tracy, the foreman. "Joe Crowfoot came and warned us what was doin'. I opine them galoots must 'a' bin shootin' at you some down yander?"
