“I’ve been building one, want to see it?”
“We’d better not linger any longer, it’s getting late,” Bob urged. Now that the mystery was solved he began to feel that he and Jim couldn’t get away from the place any too quickly, besides the short day was coming to a close and it would soon be dark. The Indian followed them outside, and strolled off unceremoniously.
“He’s got some traps set in the cliffs,” Carl explained. They watched the tall grey figure striding over the snow almost as swiftly as if he were on snowshoes, and soon he was lost from sight. He stepped so lightly that he didn’t leave an imprint.
“How do you like being a ranch nurse?” Bob asked, just to make conversation as they hurried along.
“It hasn’t been so inter—” He stopped short in his answer, and for an instant the four of them stood in startled silence. To their strained ears came an unmistakable rumble.
“Is it a plane?” Jim asked softly, but he knew it wasn’t. The words were hardly out of his mouth before the rumble grew into a thunderous roar, the earth under their feet rocked as if it had a convulsion; there was a terrific boom, followed in quick succession by three more violent explosions which threw all four of them on their faces. Kramer struck an icy spot and slid twenty feet. The land behind them ripped open, a sheet of flame and smoke belched forth, carrying huge rocks, hunks of earth and ice which flew high, wide and handsome, then began to shower as far as the cliffs.
“Come on,” Bob gasped. He caught Jim’s collar and the two struggled to their feet. Carl was lying motionless some distance away, and Kramer was rolling as hard as he could roll toward the row of sheds.
“We’ll get Summers,” Jim snapped. Bending low, the Buddies raced to the prostrate guardian of the ranch, each grabbed him and then hauled him along with them toward safety. One lump of debris struck Bob’s hand a hard crack, forcing him to let go, but Jim dragged harder and after a breathless stampede, the three at last reached the open door of the shed where Kramer was picking himself up gingerly.
“Don’t go in there,” Jim shouted. “It may come down.” He thought it was safer to trust themselves to the rain of missiles than to a building which might also be destroyed and crush them under its weight. By that time Carl was gaining consciousness and he jerked himself to his feet.
“What’s the mat—”
