The room was in instant uproar, and weapons were drawn and levelled menacingly at the young mountaineer who had ordered Lum to "drop" his gun.

"Stop!" cried Emma Dean excitedly. "This man didn't fire that second shot. He has done nothing, so put away your cannon."

"That's right, folks. Ah didn't shoot, but Ah was goin' t'. Some other duffer fired the shot that hit Lum. You-all kin look at mah gun." He held it out with the muzzle toward him.

The men crowded about him, examining the cylinder to see if a cartridge had been fired from it, and taking a sniff at the muzzle.

"That's right. It ain't been fired," agreed a mountaineer, a puzzled expression appearing on his face. "Did Lum get his'n?"

"No. The bullet went through his wrist," answered Lieutenant Wingate, who, having turned up the sleeve of Bangs' coat, was peering at the wounded wrist. "Men, I'm sorry I struck him, but you see I didn't know some one was going to shoot him. I had to punch him to save my own life, expecting that he would shoot again. As it was I nearly ran into that second shot. Fetch me something—some water."

A glass of lemonade was brought, and Nora Wingate threw it into the face of the unconscious mountaineer. In the meantime, Elfreda was giving first aid to the injured wrist. Lum began to stir about this time, and, at Elfreda's suggestion, he was carried to a window where he might get more free air.

The mountaineers were puzzled. They had, by then, examined every revolver in the room, including those carried by the Overland Riders, but not one had been fired.

"Ah wants ter know who fired that shot," demanded one of them. "Somebody did, an' we're goin' to find the critter that did it. I ain't sayin' that this feller with the uniform on didn't do all right in hittin' Lum, but what we wants t' find out is who winged him in the wrist."

"I think, gentlemen, that the second shot was fired through the window. I am quite certain that it was. I sat near the window and the report of the weapon seemed to be behind me," Anne Nesbit informed them.
