The Moon Destroyers

The moon is not only the most prominent object in our heavens, but also an integral part of the earth. We are, so to speak, an astronomical unit, and we affect each other for better or for worse. We know that the gravitational attraction of the moon causes our tides, and tends to slow up the earth in her daily rotation. It has also been deemed responsible for earthquakes, causing untold suffering among earth's people. But so far the effect of the moon has been rather an inhuman affair. No man has gone to the moon to see just what conditions are there, and to observe accurately the influence that the moon and earth exercise over each other. But when interplanetary travel does come, when commerce between moon and earth may possibly assume importance in our lives, the influence of the moon upon us may be more accurately determined. And when it is, the amazing series of incidents, pictured in this story, may yet come true.
Professor Erickson, head of the International Seismographical Institute, sat with bowed head and pale face, watching the stylus of the instrument before him trace its path on the slowly revolving drum. The laboratory, situated high in the Himalayas, trembled slightly as mid-winter storms roared and whistled around it, but something quite different, and infinitely more sinister, was causing the needle to wander from its ordinarily straight path.
Suddenly, with horrible certainty, it jumped, wavered back and forth, and then moved rapidly to the right, until its black ink no longer traced a line on the white paper.
Holden, shouted Erickson to his assistant, what does the direction and distance finder tell us? The stylus has run clear off the graph.
Young Jack Holden was working feverishly over the dials and levers of the panel before him. Slender yet strong, he looked like a long-bow of stout old yew as he bent to the task. His steel gray eyes focused intently on the verniers, taking the readings. The muscles in his tanned cheeks were tight as he turned toward his superior. For a moment the very storm seemed to hush, awaiting the words. Then he spoke.
