The dynamite with wire and a battery was given to him, and Scotty was carefully rehearsed in the part he was to play. The moon was shining as the grim riders formed and set out rapidly for the foothills. Sunrise found them concealed at the base of the outlaws’ stronghold.

Mason and Scotty began their perilous climb to the semicircle of rock. It was thought to be utterly impossible to approach closer than a hundred yards to the stronghold without being challenged by the guards. It was the brave Scot’s duty to open fire the minute he was challenged and attract the outlaws’ attention while Mason was to crawl to a position where he could place the charge of dynamite to the best advantage.

When the charge was planted he was to set it off, while the Marshal was to hurl his men on the outlaws before they could recover from their surprise.

They had climbed to within seventy-five yards of the strongly guarded point, when a sharp command to halt rang out. Scotty recklessly exposed himself to view for an instant and received a bullet through the crown of his hat. Flattening his body against the rocks, he opened a hot fire in reply. Mason continued to crawl ahead fast, but cautiously, working slightly around to the right. The outlaws sent a hail of bullets down past Scotty, which the Scot returned with interest, still keeping up his pretense of attack.

Mason worked up so close that he could see the outlaws answering Scotty’s shots with their rifles. He carefully placed the dynamite charge and dropped swiftly down the ledge with wire and battery. At a safe distance from the deadly charge he turned the switch of the battery. A tremendous explosion followed.

Amid falling rocks, Scotty came racing over to him, and together they scrambled up the cliff and into the outlaws’ stronghold.

The outlaws were wild with excitement and Jim Haley was trying to rally them when a bullet from Scotty’s gun put him out of action.

Mason and Scotty dropped down behind a rock just as a volley of bullets whistled over their heads.

Ricker rallied his men and firing rapidly he gave a yell of defiance. Seeing that he had but two men behind the rock to deal with, he called to his men and they started to rush in upon them.

Pieces of rock and dirt were filling the eyes of Mason and Scotty as they crouched behind the rock and their position was getting perilous as they couldn’t return the fire without exposing themselves.
