jaws became motionless. "Is—is that mine?" he whispered hoarsely. "The jar you brought in?" Mrs. Schermerhorn asked. "I don't know, Mr. Elvin, I'm sure. Mabel Travis was supposed to bring the gum for the contest, and she forgot where—" "But mine wasn't gum." He licked his lips, uncomfortable in the focus of so many staring eyes. "A—a rocket of some sort fell in the field, just beyond the irrigation ditch. I found the cylinder inside. It might be—it could be—anything." Elvin had the strange sensation, for almost ten seconds, of looking at a motion picture film that had stopped at a single frame.

Until a competent authority analyzed the contents, the jar represented unknown danger. It might be harmless; but it could also be an explosive, a form of fuel for the rocket, perhaps even germ colonies used in biological warfare. If Bill
