I held my fire until we were within the specified distance. The newcomer was another of the Mercurian space-ships; with a feeling of joy I swung my beam until the cross-hairs of the screen rested full on the invader.

  "All ready!" I sung out.

  "If you are ready, Gridley, you may fire!" replied Jim. I pressed the gun button. The crash of the gun was followed by another report from outside as the radite shell burst against the Mercurian flyer. The deadly explosive did its work, and the shattered remains of the wreck fell, to be engulfed in the sea below.

  "That's one!" cried Jim. "I'm afraid we won't have time to hunt up the other right now. This bug told me that the other Mercurians are due here to-day, and I think we had better form ourselves into a reception committee and go up to the hole to meet them."

  * * * * *

  He sent the ship at high speed over the city until we hovered over the laboratory. We stopped for a moment, and Jim stepped to the radio telephone.

  "Hello, Williams," he said, "how are things going? That's fine. In an hour, you say? Well, speed it up as much as you can; we may call for it soon."

  He turned both stern motors to full power, and we shot up like a rocket toward the hole in the protective layer through which the invaders had entered. In ten minutes we were at the altitude of the guard ships and Jim asked if anything had been seen. The report was negative; Jim left them below the layer and sent our flyer up through the hole into space. We reached the outer surface in another ten minutes and we were none too soon. Hardly had we debouched from the hole than ahead of us we saw another Mercurian flyer. It was a lone one, and Jim bent over the captive and held a hastily made sketch before him. The sketch showed three Mercurian flyers, one on the ground, one wrecked and the third one in the air. He touched the drawing of the one in the air and pointed toward our port hole and looked questioningly at the beetle. The insect inspected the flyer in space and nodded.

  "Good!" cried Jim. "That's the third of the trio who came ahead as scouts. Get your gun ready, First Mortgage: we're going to pick him off."

  Our ship approached the doomed Mercurian. Again I waited until we were within four hundred yards; then I pressed the button which hurled it, a crumpled wreck, onto the outer surface of the heaviside layer.

  "Two!" cried Jim as we backed away.

  "Here come plenty more," I cried as I swung the searchlight. Jim left his controls, glanced at the screen and whistled softly. Dropping toward us from space were hundreds of the Mercurian ships.

  "We got here just in time," he said. "Break out your extra ammunition while I take to the hole. We can't hope to do that bunch alone, so we'll fight a rearguard action."

  * * * * *

  Since our bow gun would be the only one in action, I hastily moved the spare boxes of ammunition nearer to it while Jim maneuvered the Hadley over the hole. As the Mercurian fleet came nearer he started a slow retreat toward the earth. The Mercurians overtook us rapidly; Jim locked his controls at slow speed down and hurried to the bow gun.

  "Start shooting as soon as you can," he said. "I'll keep the magazine filled."

  I swung the gun until the cross-hairs of the screen rested full on the leading ship and pressed the button. My aim was true, and the shattered fragments of the ship fell toward me. The balance of the fleet slowed down for an instant; I covered another one and pressed my button. The ship at which I had aimed was in motion and I missed it, but I had the satisfaction of seeing another one fall in fragments. Jim was loading the magazine as fast as I fired. I covered another ship and fired again. A third one of our enemies fell in ruins. The rest paused and drew off.

  "They're retreating, Jim!" I cried.

  "Cease firing until they come on again," he replied is he took the shells from the magazines of the other guns and piled them near the bow gun.

  I held my fire for a few minutes. The Mercurians retreated a short distance and then came on again with a rush. Twenty times my gun went off as fast as I could align it and press the trigger, and eighteen of the enemy ships were in ruins. Again the Mercurians retreated. I held my fire. We were falling more rapidly now and far below we could see the black spots which were the guard ships. I told Jim that they were in sight; he stepped to the radio telephone and ordered them to keep well away from the hole.

  * * * * *

  Again the Mercurian ships came on with a rush, this time with beams of orange light stabbing a way before them. When I told Jim of this he jumped to the controls and shot our ship down at breakneck speed.

  "I don't know what sort of fighting apparatus they have, but I don't care to face it," he said to me. "Fire if they get close; but I hope to get out of the hole before they are in range."

  Fast as we fell, the Mercurians were coming faster, and they were not over eight hundred yards from us when he reached the level of the guard ships. Jim checked our speed; I managed to pick off three more of the invaders before we moved away from the hole. Jim stopped the side motion and jumped to the radio telephone.

  "Hello, Williams!" he shouted into the instrument. "Are you ready down there? Thank God! Full power at once, please!

  "Watch what happens," he said to me, as he turned from the instrument.

  Some fifty of the Mercurian flyers had reached our level and had started to move toward us before anything happened. Then from below came a beam of intolerable light. Upward it struck, and the Mercurian ships on which it impinged disappeared in a flash of light.

  "A disintegrating ray," explained Jim. "I suspected that it might be needed and I started Williams to rigging it up early this morning. I hated to use it because it may easily undo the work that six years have done in healing the break in the layer, but it was necessary. That ends the invasion, except for those ten or twelve ships ahead of us. How is your marksmanship? Can you pick off ten in ten shots?"

  "Watch me," I said grimly as the ship started to move.

  * * * * *

  Pride goeth ever before a fall: it took me sixteen shots to demolish the eleven ships which had escaped destruction from the ray. As the last one fell in ruins, Jim ordered the ray shut off. We fell toward the ground.

  "What are we going to do with our prisoner?" I asked.

  Jim looked at the beetle meditatively.

  "He would make a fine museum piece if he were stuffed," he said, "but on the whole, I think we'll let him go. He is an intelligent creature and will probably be happier on Mercury than anywhere else. What do you say that we put him on his ship and turn him loose?"

  "To lead another invasion?" I asked.

  "I think not. He has seen what has happened to this one and is more likely to warn them to keep away. In any event, if we equip the guard ships with a ray that will show the Mercurian ships up and keep the disintegrating ray ready for action, we needn't fear another invasion. Let's let him go."

  "It suits me all right, Jim, but I hold out for one thing. I will never dare to face McQuarrie again if I fail to get a picture of him. I insist on taking his photograph before we turn him loose."

  "All right, go ahead," laughed Jim. "He ought to be able to stand that, if you'll spare him an interview."

  An hour later we watched the Mercurian flyer disappear into space.

  "I hope I've seen the last of those bugs," I said as the flyer faded from view.

  "I don't know," said Jim thoughtfully. "If I have interpreted correctly the drawings that creature made, there is a race of manlike bipeds on Mercury who are slaves to those beetles and who live and die in the horrible atmosphere of a radium mine. Some of these days I may lead an expedition to our sister planet and look into that matter."

  MECHANICAL VOICES FOR PHONE NUMBERS

  New developments whereby science goes still farther in its assumption of human attributes were described and demonstrated recently by Sergius P. Grace, Assistant Vice-President of Bell Telephone Laboratories, where the developments were conceived and worked out.

  One development described, and soon to be put into service in New York, transforms a te
lephone number dialed by a subscriber into speech. Although the subscriber says not a word the number dialed is spoken aloud to the operator.

  The device is expected to simplify and speed the hooking together of automatic and voice-hand-operated telephone exchanges, and also to speed long-distance calls from automatic phones through rural exchanges.

  The numbers which can thus be spoken are recorded on talkie films and those which are to go into use here have already been made, all by an Irish girl said to have the best voice among the city's "number, please" girls.

  Mr. Grace demonstrated this device by carrying into the audience a telephone with a long cord connected with a loud speaker on the stand, which represented central. A member of the audience was requested to dial a number, and choose 5551-T, the letter T representing the exchange.

  This number the spectator dialed on the phone Mr. Grace carried. There was no sound but the clicking of the dial. Then, two seconds later, the loudspeaker spoke up clearly, in an almost human voice, "5551 T."

  As for the recording of the sound films, there is a film for each of the ten Arabic numerals from zero to nine, and these wound on revolving drums. The dial on the telephone automatically sets in action the drum corresponding to the numeral moved on the dial.

  Another development which sounds promising for bashful suitors and other timid souls, enables a person to store within himself electrically a message he desires to deliver and then to deliver it without speaking, simply by putting a finger to the ear of the person for whom the message is intended.

  This Mr. Grace demonstrated. He spoke into a telephone transmitter and his words were clearly heard by all in the audience, by means of amplifiers. At the same time a part of the electrical current from the amplifier, representing the sentence he voiced, was stored in a "delay circuit," another recent invention of the laboratories. After being stored four and a half seconds this current was transformed to a high voltage and passed into Mr. Grace's body. He then put his finger against the ear of a member of the audience, who heard in his brain the same sentence. The ear drum and surrounding tissues are made to act as one plate of a condenser-receiver, Mr. Grace explained, with the vibrations of the drum interpreted by the brain.

  A new magnetic metal, "perminvar," and a new insulating material, "para gutta," which make possible construction of a telephone cable across the Atlantic to supplement the radio systems, were also described. Actual construction of the cable is expected to be started in 1930, Mr. Grace said.

  Earth, the Marauder

  CONCLUSION OF A THREE-PART NOVEL

  By Arthur J. Burks

  CHAPTER XIX - Desolation

  Stranger, more thrilling even than had been the flight of the Earth after being forced out of its orbit, was the flight of those dozen aircars of the Moon, bearing the rebels of Dalis' Gens back to Earth.

  [Sidenote: Martian fire-balls and the terrific Moon-cubes wreak tremendous destruction on helpless Earth in the final death struggle of the warring worlds.]

  For the light which glowed from the bodies of the rebels, which had been given them by their passage through the white flames, was transmitted to the cars themselves, so that they glowed as with an inner radiance of their own--like comets flashing across the night.

  Strange alchemy, which Sarka wondered about and, wondering, looked ahead to the time when he should be able, within his laboratory, to analyze the force it embodied, and thus gain new scientific knowledge of untold value to people of the Earth.

  As the cars raced across outer darkness, moving at top speed, greater than ever attained before by man, greater than even these mighty cars had traveled, Sarka looked ahead, and wondered about the fearful report his father had just given him.

  That there was an alliance between Mars and the Moon seemed almost unbelievable. How had they managed the first contact, the first negotiations leading to the compact between two such alien peoples? Had there been any flights exchanged by the two worlds, surely the scientists of Earth would have known about it. But there had not, though there had been times and times when Sarka had peered closely enough at the surface of both the Moon and of Mars to see the activities, or the results of the activities, of the peoples of the two worlds.

  Somehow, however, communication, if Sarka the Second had guessed correctly, had been managed between Mars and the Moon; and now that the Earth was a free flying orb the two were in alliance against it, perhaps for the same reason that the Earth had gone a-voyaging.

  * * * * *

  Side by side sat Sarka and Jaska, their eager eyes peering through the forward end of the flashing aircar toward the Earth, growing minute by minute larger. They were able, after some hours, to make out the outlines of what had once been continents, to see the shadows in valleys which had once held the oceans of Earth....

  And always, as they stared and literally willed the cubes which piloted and were the motive power of the aircars to speed and more speed, that marvelous display of interplanetary fireworks which had aroused the concern of Sarka the Second.

  What were those lights? Whence did they emanate? Sarka the Second had said that they came from Mars, yet Mars was invisible to those in the speeding aircars, which argued that it was hidden behind the Earth. There was no way of knowing how close it was to the home of these rebels of Dalis' Gens.

  And ever, as they flashed forward, Sarka was recalling that vague hint on the lips of Jaska, to the effect that Luar, for all her sovereignty of the Moon, might be, nonetheless, a native of the Earth. But....

  How? Why? When? There were no answers to any of the questions yet. If she were a native of Earth, how had she reached the Moon? When had she been sent there? Who was she? Her name, Luar, was a strange one, and Sarka studied it for many minutes, rolling the odd syllables of it over his tongue, wondering where, on the Earth, he had heard names, or words, similar to it. This produced no result, until he tried substituting various letters; then, again, adding various letters. When he achieved a certain result at last, he gasped, and his brain was a-whirl.

  * * * * *

  Luar, by the addition of the letter n, between the u and the a, became Lunar, meaning "of the Moon!" Yet Lunar was unmistakably a word derived from the language of the Earth! It was possible, of course, that this was mere coincidence; but, taken in connection with the suspicions of Jaska, and the incontrovertible fact that Luar resembled people of the Earth, Sarka did not believe in this particular whim of coincidence.

  Who was Luar?

  His mind went back to the clucking sounds which, among the Gnomes of the Moon, passed for speech. He pondered anew. He shaped his lips, as nearly as possible, to make the clucking sounds he had heard, and discovered that it was very difficult to manage the letter n!

  The conclusion was inescapable: This woman, Luar, had once been Lunar, the n, down the centuries, being dropped because difficult for the Gnomes to pronounce.

  "Yes, Jaska," he said suddenly, "somewhere on Earth, when we reach it, we may discover the secret of Luar--and know far more about Dalis than we have ever known before!"

  Jaska merely smiled her inscrutable smile, and did not answer. By intuition, she already knew. Let Sarka arrive at her conclusion by scientific methods if he desired, and she would simply smile anew.

  Sarka thought of the manner in which Jaska and he had been transported to the Moon; of how much Dalis seemed to know of the secrets of the laboratory of the Sarkas. Might he not have known, two centuries ago, of the Secret Exit Dome, and somehow managed to make use of it in some ghastly experiment? And still the one question remained unanswered: Who was Luar?

  * * * * *

  The Earth was now so close that details were plainly seen. The Himalayas were out of sight, over the Earth, and by a mental command Sarka managed to change slightly the course of the dozen aircars. By passing over the curve of the Earth at a high altitude, he hoped also to see from above something of the result of the strange aerial bombardment of which his father had spoken.

  In their flig
ht, which had been, to them a flight through the glories of a super-heavenly Universe, they had lost all count of time. Neither Sarka nor Jaska, nor yet the people in those other aircars, could have told how long they had been flying, when, coming over the curve of the Earth, at an elevation of something like three miles, they were able at last to see into the area which had once housed the Gens of Dalis.

  A gasp of horror escaped the lips of Sarka and of Jaska.

  The Gens of Dalis had occupied all the territory northward to the Pole, from a line drawn east and west through the southernmost of what had once been the Hawaiian Islands. Upon this area had struck the strange blue light from the deep Cone of the Moon.

  Here, however, the light was invisible, and Sarka flew on in fear that somehow his aircars would blunder into it, and be destroyed--for that the blue light was an agent of ghastly destruction became instantly apparent.

  * * * * *

  The dwellings of the Gens of Dalis were broken and smashed into chaotic ruins. Over all the area, and even into the area of the Gens southward of that which had been Dalis, the blind gods of destruction had practically made a clean sweep. Sarka had opportunity to thank God that, at the time the blue column had struck the Earth, it had struck at the spot which had been almost emptied of people, and realized that blind chance had caused it. For, in order for the Gens of Dalis to be in position to launch their attack against the Moon, he had managed, by manipulating the speed of the Beryls, to bring that area into position directly opposite the Moon.

  Had it been otherwise, the blue column might have struck anywhere, and wiped out millions of lives!

  "God, Jaska," murmured Sarka. "Look!"

  Think of a shoreline, once lined with mighty buildings, after the passage of a tidal wave greater than ever before known to man. The devastation would be indescribable. Multiply that shoreline by the vast area which had housed the Gens of Dalis, and the mental picture is almost too big to grasp. Chaos, catastrophe, approaching an infinity of destruction.
