Bart clenched his fist and brought it down in a sudden sweeping blow that raked Kelly's cheek and ear with stunning force. But the gunman recovered in a flash, dropped the muzzle of his pistol and pulled the trigger. Drilled through the thigh, Bart staggered through the open door and fell the length of the stairs into the darkness of the cellar. Kelly laughed evilly as he slammed the door and turned the key.
"Hold it, you!" he snarled as he swung on Van who had dropped his hands and crouched for a spring. "If I drill you, it won't be through the leg. I'll take those diamonds now."
e pocketed one of his pistols, and, keeping the other pressed to the pit of Van's stomach, went through his pockets. Then he added those on the tray by the crystal bowl to the collection, and transferred the entire lot to his own pocket.
"Now, you clever engineer," he grinned, "we'll just operate this trick machine of yours for a while and collect some more. Hop to it!" He watched narrowly as Van stretched his fingers to the controls. "No monkey business, either," he grated; "you'll not change a single adjustment. I've been listening to you and I know the clock of the telescope is keeping the ray trained on the same spot. You just operate the ray and nothing else. Get me?"
Van did not think it expedient to tell him of the drift caused by inaccuracies in the clock and perturbations of the moon's motion. He was playing for time, trying to plan a course of action.
"There may not be any more diamonds," he offered as he tripped the release of the ray.
"Oh, there'll be more. Don't try to kid me."
An irregular block of quartz materialized in the bowl and Kelly tossed it to the floor in savage disgust. Then a small diamond, very small; but he pocketed it nevertheless. The next object was a strange one—a dried seed pod about six inches in length and of brilliant red color. The ray had shifted to a new position on the lunar surface. Another and another of the strange legumes followed, one of them bursting open and scattering its contents, bright red like the enclosing pod to rattle over the floor like tiny glass beads. Kelly snorted his disgust.
