Not one out of ten escapes this social fault Can you be sure that you never have halitosis (unpleasant breath)? Are you certain at this very moment, that you are free of it? The insidious thing about this unforgivable social fault is that you, yourself, never know when you have it; the victim simply cannot detect it. Remember, also, that anyone is likely to be troubled, since conditions capable of causing halitosis arise frequently in even normal mouths. Fermenting food particles, de- fective or decaying teeth, pyor- I I Q T C D I C rhea, catarrh, and slight infec- L 1 V 1 U ,X 1 1 ™ U tions in the mouth, nose, and I I • throat— all produce odors. You QDOS ilOllTOSIS can get rid of these odors instantly by gargling and rinsing the mouth with full strength Listerine. Every morning. Every night. And between times before meeting others. Listerine halts fermentation because it is an antiseptic. It checks infection because it is a remarkable germi- cide.* And it quickly overcomes odors because it is a, rapid and powerful deodorant.

"Bond," he asked, "do you know Jim Carpenter?" "I know him slightly," I replied cau- tiously. "I have met him several times and I inter- viewed him some years ago when he improved the For •iffiit'f vertical miles Carpenter and Bond Malted their way— only to be trapped by the extraordinary monsters of the heaviside layer. motor. 4 can't claim a very, extensive acquaintance with him." "I thought you knew him well. It is a surprise to me to find that there is any prominent man who is not an especial friend of yours. At any rate you know him as well as anyone of the staff, so I'll givt you the assignment." "What's he up to now?" I asked. "He's going to try to punch a hole in the heaviside layer." "But that's im- possible," I cried. "How _ can any- one. . . ." My voice died away in silence. True enough, the idea of trying to make a permanent hole in a field of magnetic force was absurd, but even as i spoke I rem em- 6 ASTOUNDING STORIES H bered that Jim Carpenter had never agreed to the opinion almost unani- mously held by our scientists as to the true nature of the heaviside layer. "It may be impossible," replied Mc- Quarrie dryly, "but you are not hired by this paper as a scientific consultant. For some reason, God alone knows why, the owner thinks that you are a re- porter. Get down there and try to prove he is right by digging up a few facts about Carpenter's attempt. Wire your stuff in and Peavey will write it up. On this one occasion, please try to con- ceal your erudition and send in your story in simple words of one syllable which uneducated men like Peavey and me can comprehend. That's all." E turned again to his desk and I left the room. At one time I would have come from such an inter- view with my face burning, but Mc- "Quarrie's vitriol slid off me like water o»ff a duck's back. He didn't really mean half of what he said, and*ne knew as well as I did that his crack about my plding my job with the Clarion as a er of pull was grossly unjust. It > true that I knew Trimble, the owner If the Clarion, fairly well, but I got \y job without any aid from him. Mc- Juarrie himself hired me and I held ny job because he hadn't fired me, de- spite the caustic remarks which he ad- dressed to me. I had made the mistake when I first got on the paper of letting McQuarrie know that I was a graduate electrical engineer from Leland Uni- versity, and he had held it against me from that day on. I don't know whether he really held it seriously against me or not, but what I have written above is a fair sample of his usual manner toward me. . In point of fact I had greatly mini- mized the extent of my acquaintance with Jim Carpenter. I had been in Le- land at the same time that he was and had known him quite well. When I graduated, which was two years after he did, I worked for about a year in his laboratory, and,; my knowledge of the improvement which had made the Had- ley rocket motor a practicability came from first hand knowledge and not 'from an interview. That was several years before but I knew that he never forgot an acquaintance, let alone a friend, and while I had left him to take up other work our parting had been pleasant, and I looked forward with real pleasure to seeing him again. JIM CARPENTER, the stormy petrel of modern science I The eternal iconoclast ; the perpetual opponent I He was probably as deeply versed in the theory of electricity and physical chem- istry as any man alive, but it pleased him to. pose as a "practical" man who knew next to nothing of theory and who despised the little he did know. His great delight was to experimental- ly smash the most beautifully con- structed theories which were advanced and taught in the colleges and uni- versities of the world, and when he couldn't smash them by experimental evidence, to attack them from the stand- point of philosophical reasoning and to twist around the data on which they were built and make it prove, or seem to prove, the exact opposite of what was generally accepted. No one questioned his ability. When the ill-fated Hadley had first con- structed the rocket motor which bears his name it was Jim Carpenter who made it practical, Hadley had tried to disintegrate leaty in order to get his back thrust from the atomic energy which it contained and proved by ap- parently unimpeachable mathematics that lead was the only substance which could be used. Jim Carpenter had snorted through the pages of the elec- trical journals and had turned out a modification of Hadley's invention which disintegrated aluminum. The main difference in performance was that, while Hadley's original motor would not, develop enough power to lift itself from the ground. Carpenter's modification produced twenty times the horsepower per pound of, weight BEYOND THE HEA VISIDE "LAYER T of any previously known generator of power, and changed the rocket ship front* a wild dream to an everyday com- monplace. HEN Hadley later constructed his space flyer and proposed to . - visit the moon, it was Jim Carpenter who ridiculed the idea of the attempt being successful. 'He proposed the novel and weird' idea that the path to space was not open, but that the earth and the atmosphere were enclosed in a hollow sphere of impenetrable sub- stance through which Hadley's space flyer coul
