helium in a liquid state.”
“Where is your compressor?”
“I didn’t have to use one. I developed a cold light under whose rays helium would liquefy and remain in a state of equilibrium until exposed to light rays. Those cylinders had merely enough pressure to force the liquid out to where the sun could hit it, and then it turned to a gas, dropping the temperature at the first focal point of the reflector to absolute zero. When I had this much done, Koskoff and I packed the whole apparatus here and were ready for work.
“We were on the path of the transcontinental air mail, and I bided my time until an especially valuable shipment was to be made. My plans, which worked perfectly, were to freeze the plane in midair and then rob the wreck. I heard of the jewel shipment the T. A. C. was to carry and I planned to get it. When the plane came over, Koskoff and I brought it down. The unsuspected presence of another plane upset us a little, and I started to bring it down. But we had been all over this country and knew there was no place that a plane could land. I let it go on in safety.”
“Thank you,” replied Carnes with a grimace.
“We robbed the wreck and we found two packets, one the jewels I was after, and the other a sealed packet, which proved to contain certain War Department plans. That was when I learned who Koskoff was. I had hired him in San Francisco as a good mechanic who had no principles. He was to get one-fourth of the loot. When we found these plans, he told me who he was. He was really a Russian secret agent and he wanted to deliver the plans to Russia. I may be a thief and a murderer, but I am not yet ready to betray my country, and I told him so. He offered me almost any price for the plans; but I wouldn’t listen. We had a serious quarrel, and he overpowered me and bound me.
“We had a radio set here and he called San Francisco and sent some code message. I think he was waiting here for someone to come. Had we followed our original plans, we would have been miles from here before you arrived.
“He had me bound and helpless, as he thought, but I worked my bonds a little loose. I didn’t let him know it, for I knew that the plane I had let get away would guide a party here and I thought I might be able to help out. When you came and attacked the house, I worked at my bonds until they were loose enough to throw off. I saw Koskoff start my cold apparatus to working and then he quit, because he ran out of helium. When he started shooting again, I worked out of my bonds and tackled him.
“He was a better man than I gave him credit for, or else he suspected me, for about the time I grabbed him he whirled and struck me over the head with his gun barrel and tore my face open. The blow stunned me, and when I came to, I was thrown into this corner. I meant to have another try at it, but I guess you rushed him too fast. He turned and ran for the tunnel, but as he did so, he shot me through the body. I guess I didn’t look dead enough to suit him. You gentlemen broke open the door and came in. That’s all.”
“Not by a long shot, it isn’t,” exclaimed Dr. Bird. “Where is that cold light apparatus of yours?”
“In the tunnel.”
“How do you get into it?”
“If you will open that cupboard on the wall, you’ll find an open knife switch on the wall. Close it.”
Dr. Bird found the switch and closed it. As he did so the cabin rocked on its foundations and both Carnes and Walter were thrown to the ground. The thud of a detonation deep in the earth came to their ears.
“What was that?” cried the doctor.
“That,” replied Smith with a wan smile, “was the detonation of two hundred pounds of T.N.T. When you dig down into the underground cave where we used the cold light apparatus, you will find it in fragments. It was my only child, and I’ll take it with me.”
As he finished his head slumped forward on his chest. With an exclamation of dismay Dr. Bird sprang forward and tried to lift the prostrate form.
In an agony of desire the Doctor tightened his grip on the dying man’s shoulder. But Smith collapsed into a heap. Dr. Bird bent forward and tore open his shirt and listened at his chest. Presently he straightened up.
“He is gone,” he said sadly, “and I guess the results of his genius have died with him. He doesn’t strike me as a man who left overmuch to chance. Carnes, is your case completed?”
“Very satisfactorily, Doctor. I have both of the lost packets.”
“All right, then, come back to the wreck and help me pack my burros. I can make my way back to Fallon without a guide.”
“Where are you going, Doctor?”
“That, Carnes, old dear, is none of your blankety blanked business. Permit me to remind you that I am on my vacation. I haven’t decided yet just where I am going, but I can tell you one thing. It’s going to be some place where you can’t call me on the telephone.”
Brigands of the Moon
I have been thinking that if, during one of those long winter evenings at Valley Forge, someone had placed in George Washington’s hands one of our present day best sellers, the illustrious Father of our Country would have read it with considerable emotion. I do not mean what we call a story of science, or fantasy–just a novel of action, adventure and romance. The sort of thing you and I like to read, but do not find amazing in any way at all.
Black mutiny and brigandage stalk the Space-ship Planetara as she speeds to the Moon to pick up a fabulously rich cache of radium-ore.
But I fancy that George Washington would have found it amazing. Don’t you? It might picture, for instance, a factory girl at a sewing machine. George Washington would be amazed at a sewing machine. And the girl, journeying in the subway to and from her work! Stealing an opportunity to telephone her lover at the noon hour; going to the movies in the evening, or listening to a radio. And there might be a climax, perhaps, with the girl and the villain in a transcontinental railway Pullman, and the hero sending frantic telegrams, or telephoning the train, and then chasing it in his airplane.
George Washington would have found it amazing!
And I am wondering how you and I would feel if someone were to give us now a book of ordinary adventure of the sort which will be published a hundred and fifty years hence. I have been trying to imagine such a book and the nature of its contents.
Let us imagine it together. Suppose we walk down Fifth Avenue, a pleasant spring morning of May, 2080. Fifth Avenue, no doubt, will be there. I don’t know whether the New York Public Library will be there or not. We’ll assume that it is, and that it has some sort of books, printed, or in whatever fashion you care to imagine.
The young man library attendant is surprised at our curiously antiquated aspect. We look as though we were dressed for some historical costume ball. We talk old-fashioned English, like actors in an historical play of the 1930 period.
But we get the book. The attendant assures us it is a good average story of action and adventure. Nothing remarkable, but he read it himself, and found it interesting.
We thank him and take the book. But we find that the language in which it is written is too strange for comfortable reading. And it names so many extraordinary things so casually! As though we knew all about them, which we certainly do not!
So we take it to the kind-hearted librarian in the language division. He modifies it to old-fashioned English of 1930, and he puts occasional footnotes to help explain some of the things we might not understand. Why he should bother to do this for us I don’t know; but let us assume that he does.
And now we take the book home–in the pneumatic tube, or aerial moving sidewalk, or airship, or whatever it is we take to get home.
And now that we are home, let’s read the book. It ought to be interesting.
