"Now, old fellow," he said grimly, "either you run this ship as I want you to, or you're a dead Indian. Savvy?"
He took his pencil and notebook from his pocket and drew a sketch of our Hadley space ship. On the other end of the sheet he drew a picture of the Mercurian ship, and then drew a line connecting the two. The insect looked at the sketch but made no movement.
"All right, if that's the way you feel about it," said Jim. He raised the bar and brought it down with crushing force on one of the insect's lower arms. The arm fell as though paralyzed and a blue light played across the beetle's eyes. Jim extended the sketch again and raised the bar threateningly. The beetle moved over to the control board, Jim following closely, and set the ship in motion. Ten minutes later it rested on the ground beside the ship in which we had first taken the air.
* * * * *
Following Jim's pictured orders the beetle opened the door of the Mercurian ship and followed Jim into the Hadley. As we emerged from the Mercurian ship I looked back. It had vanished completely.
"The children, Jim!" I gasped.
"I haven't forgotten them," he replied, "but they are all right for the present. If we turned them loose now, we'd have ninety reporters around us in ten minutes. I want to get our generators modified first."
He pointed toward the spot where the Mercurian ship had stood and then toward our generators. The beetle hesitated, but Jim swung his bar against the insect's side in a vicious blow. Again came the play of blue light over the eyes; the beetle bent over our generaters and set to work. Jim handed me the bar and bent over to help. They were both mechanics of a high order and they worked well together; in an hour the beetle started the generators and swung one of the searchlights toward his old ship. It leaped into view on the radium coated screen.
"Good business!" ejaculated Jim. "We'll repair this door; then we'll be ready to release the children and start out."
* * * * *
We followed the beetle into the Mercurian ship, which it seemed to be able to see. It opened a door leading into another compartment of the flyer, and before us lay the bodies of eight children. The beetle lifted the first one, a little girl, up until his many-faceted eyes looked full into the closed ones of the child. There was a flicker of an eyelash, a trace of returning color, and then a scream of terror from the child. The beetle set the girl down and Jim bent over her.
"It's all right now, little lady," he said, clumsily smoothing her hair.
"You're safe now. Run along to your mother. First Mortgage, take charge of her and take her outside. It isn't well for children to see these things."
The child clung to my hand: I led her out of the ship, which promptly vanished as we left it. One by one, seven other children joined us, the last one, a miss of not over eight, in Jim's arms. The beetle followed behind him.
"Do any of you know where you are?" asked Jim as he came out.
"I do, sir," said one of the boys. "I live close to here."
"All right, take these youngsters to your house and tell your mother to telephone their parents to come and get them. If anyone asks you what happened, tell them to see Jim Carpenter to-morrow. Do you understand?"
"Yes, sir."
"All right, run along then. Now, First Mortgage, let's go hunting."
* * * * *
We wired our captive up so securely that I felt that there was no possible chance of his escape; then, with Jim at the controls and me at the guns, we fared forth in search of the invaders. Back and forth over the city we flew without sighting another spaceship in the air. Jim gave an exclamation of impatience and swung on a wider circle, which took us out over the water. I kept the searchlights working. Presently, far ahead over the water, a dark spot came into view. I called to Jim and we approached it at top speed.
"Don't shoot until we are within four hundred yards," cautioned Jim.
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 belo
w 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."

THE BLACK LAMP
By Captain S. P. Meek
"The clue, Carnes," said Dr. Bird slowly, "lies in those windows."
Operative Carnes of the United States Secret Service shook his head before he glanced at the windows of the famous scientist's private laboratory on the top floor of the Bureau of Standards.
Dr. Bird and his friend Carnes unravel another criminal web of scientific mystery.
"I usually defer to your knowledge, Doctor," he said, "but this time I think you are off on the wrong foot. If the thieves came in through the windows, what was their object in cutting that hole through the roof? The marks are very plain and they indicate that the hole was cut in some manner from the inside."
Dr. Bird smiled enigmatically.
"That is too evident for discussion," he replied. "I grant you that the thieves entered from the roof through that hole. After they had secured their booty they left by the same route. I presume that you have noticed the marks on the roof where an aircraft of some sort, probably a helicopter, landed and took off. A question of much greater moment is that of what they did before they landed and cut the hole."
"I don't follow your reasoning, Doctor."
"Carnes, that hole was cut through the roof with a heavy saw. In cutting it, the workers dislodged quite a little plaster which fell to the floor and must have made a great deal of noise. Why wasn't that noise heard?"
"It was heard. The watchman heard it, but knew that Lieutenant Breslau was working here and he thought that he made the noise."
"Surely, but why didn't Breslau hear it?"
"How do we know that he didn't? He was taken to Walter Reed Hospital this morning with his mind an absolute blank and with his tongue paralyzed. He must have seen the thieves and they treated him in some way to ensure his silence. When he is able to talk, if he ever is, he'll probably give us a good description of them."
Dr. Bird shook his head.
"Too thin, Carney, old dear," he said. "Breslau is a very intelligent young man. He was perfectly normal when I left him shortly after midnight last night. He was working alone in here on a device of the utmost military importance. On the desk is a push button which sets ringing a dozen gongs in the building. Surely a man of that type would have had sense enough when he heard and saw intruders cutting a hole through the roof to sound an alarm which would have brought every watchman on the grounds to his assistance. He must have been knocked out before the hole was started, probably before the helicopter's landing."
"How? Gas of some sort?"
"The windows were all closed and locked and I have already ascertained that the gas and water lines have not been tampered with. Gas won't penetrate through a solid roof in sufficient concentration to knock out a man like that. It was something more subtle than gas."
"What was it?"
"I don't know yet. The clue to what it was lies, as I told you, in those windows."
Carnes moved over and surveyed the windows closely.
"I see nothing unusual about them except that they need washing rather badly."
"They were washed last Friday, but they do look rather dirty, don't they? Suppose you take a rag and some scouring soap and clean up a pane."
The detective took the proffered articles and started his task. He wet a pane of glass, rubbed up a thick lather of scouring soap and applied it and rubbed vigorously. With clear water he washed the glass and then gave an exclamation of astonishment and examined it more closely.
"That isn't dirt, Doctor," he cried. "The glass seems to be fogged."
Dr. Bird chuckled.
"So it seems," he admitted. "Now look at the rest of the glass around the laboratory."
Carnes looked around and then walked to a table littered with apparatus and examined a dozen pieces carefully.
"It's all fogged in exactly the same way, Doctor," he said. "The only piece of clear glass in the room is that piece of plate glass on your desk."
Dr. Bird picked up a hammer and struck the plate on his desk a sharp blow. Carnes ducked instinctively, but the hammer rebounded harmlessly from the plate.
"That isn't glass, Carnes," said the doctor. "That plate is made of vitrilene, a new product which I have developed. It looks like glass, but it has entirely different properties. It is of enormous strength and is quite insensitive to shock. It has one most peculiar property. While ultra-violet and longer rays will penetrate it quite readily, it is a perfect screen for X-rays and oth
er rays of shorter wave length. It appears to be the only piece of transparent substance in my laboratory which has not been fogged, as you call it."
"Do short waves fog glass, Doctor?"
"Not so far as I know at present, but you must remember that very little work has been done with the short wave-lengths. In the vast range of waves whose lengths lie between zero and that of the X-ray, only a few points have been investigated and definitely plotted. There may be in that range a wave-length which will fog glass."
"Then your theory is that some sort of a ray machine was put in operation before the helicopter landed?"
"It is too early to attempt any theorizing, Carnes. Let us confine ourselves to the known facts. Lieutenant Breslau was normal at midnight and was working in this room. Some time between then and seven this morning he underwent certain mental and physical changes which prevent him from telling us what he observed. During the same period, a hole was cut in the roof and things of great importance stolen. At the same time, all the glass in the laboratory became semi-opaque. The problem is to determine what connection there is between the three events. I will handle the scientific end here, but there is some outside work to be done, and that will be your share."
Give your orders, Doctor," said the detective briefly.
"To understand what I am driving at, I will have to tell you what has been stolen. Naturally this is highly confidential. Some rumors have leaked out as to my experiments with 'radite,' as I have named the new radium-containing disintegrating explosive on which I have been working, but no one short of the Secretary of War and the Chief of Ordnance and certain of their selected subordinates knows that my experiments have been successful and that the United States is in a position to manufacture radite in almost unlimited quantities from the pitchblende ore deposits of Wyoming and Nevada. The effects of radite will be catastrophic on the unfortunate victim on whom it is first used. The only thing left to do was to develop a gun from which radite shells could be fired with safety and precision.
