the language which came over that telephone. I was informed that all reporters were pests and that I was a doubly obnoxious specimen and that were I within reach I would be promptly assaulted and that reporters would be received at nine the next morning and no earlier or later.

"Just a minute, Mr. Carpenter," I cried as he neared the end of his peroration and was, I fancied, about to slam up the receiver. "Don't you remember me? I was at Leland with you and used to work in your laboratory in the atomic disintegration section."

"What's your name?" he demanded.

"Bond, Mr. Carpenter."

"Oh, First Mortgage! Certainly I remember you. Mighty glad to hear your voice. How are you?"

"Fine, thank you, Mr. Carpenter. I would not have ventured to call you had I not known you. I didn't mean to impose and I'll be glad to see you in the morning at nine."

"Not by a long shot," he cried. "You'll come up right away. Where are you staying?"

"At the El Rey."

"Well, check out and come right up here. There's lots of room for you here at the plant and I'll be glad to have you. I want at least one intelligent report of this experiment and you should be able to write it. I'll look for you in an hour."

"I don't want to impose—" I began; but he interrupted.

"Nonsense, glad to have you. I needed someone like you badly and you have come just in the nick of time. I'll expect you in an hour."

The receiver clicked and I hastened to follow his instructions. A ringside seat was just what I was looking for. It took my taxi a little over an hour to get to the Carpenter laboratory and I chuckled when I thought of how McQuarrie's face would look when he saw my expense account. Presently we reached the edge of the grounds which surrounded the Carpenter laboratory and were stopped at the high gate I remembered so well.

"Are you sure you'll get in, buddy?" asked my driver.

"Certainly," I replied. "What made you ask?"

"I've brought three chaps out here to-day and none of them got in," he answered with a grin. "I'm glad you're so sure, but I'll just wait around until you are inside before I drive away."

I laughed and advanced to the gate. Tim, the old guard, was still there, and he remembered and welcomed me.

"Me ordhers wuz t' let yez roight in, sor," he said as he greeted me. "Jist lave ye'er bag here and Oi'll have ut sint roight up."

I dropped my bag and trudged up the well remembered path to the laboratory. It had been enlarged somewhat since I saw it last and, late though the hour was, there was a bustle in the air and I could see a number of men working in the building. From an area in the rear, which was lighted by huge flood lights, came the staccato tattoo of a riveter. I walked up to the front of the laboratory and entered. I knew the way to Carpenter's office and I went directly there and knocked.

"Hello, First Mortgage!" cried Jim Carpenter as I entered in response to his call. "I'm glad to see you. Excuse the bruskness of my first greeting to you over the telephone, but the press have been deviling me all day, every man jack of them trying to steal a march on the rest. I am going to open the whole shebang at nine to-morrow and give them all an equal chance to look things over before I turn the current on at noon. As soon as we have a little chat, I'll show you over the works."

After half an hour's chat he rose. "Come along, First Mortgage," he said, "we'll go out and look the place over and I'll explain everything. If my ideas work out, you'll have no chance to go over it to-morrow, so I want you to see it now."

I had no chance to ask him what he meant by this remark, for he walked rapidly from the laboratory and I perforce followed him. He led the way to the patch of lighted ground behind the building where the riveting machine was still beating out its monotonous cacaphony and paused by the first of a series of huge reflectors, which were arranged in a circle.

"Here is the start of the thing," he said. "There are two hundred and fifty of these reflectors arranged in a circle four hundred yards in diameter. Each of them is an opened parabola of such spread that their beams will cover an area ten yards in diameter at fifty miles above the earth. If my calculations are correct they should penetrate through the layer at an average speed of fifteen miles per hour per unit, and by two o'clock to-morrow afternoon, the road to space should be open."

"What is your power?" I asked.

"Nothing but a concentration of infra-red rays. The heaviside layer, as you doubtless know, is a liquid and, I think, an organic liquid. If I am right in that thought, the infra-red will cut through it like a knife through cheese."

"If it is a liquid, how will you prevent it from flowing back into the hole you have opened?" I asked.

"When the current is first turned on, each reflector will bear on the same point. Notice that they are moveable. They are arranged so that they move together. As soon as the first hole is bored through, they will move by clockwork, extending the opening until each points vertically upward and the hole is four hundred yards in diameter. I am positive that there will be no rapid flow even after the current is turned off, for I believe that the liquid is about as mobile as petroleum jelley. Should it close, however, it would take only a couple of hours to open it again to allow the space flyer to return."

"What space flyer?" I demanded quickly.

"The one we are going to be on, First Mortgage," he replied with a slight chuckle.

We?" I cried, aghast.

"Certainly. We. You and I. You didn't think I was going to send you alone, did you?"

"I didn't know that anyone was going."

"Of course. Someone has to go; otherwise, how could I prove my point? I might cut through a hundred holes and yet these stiff-necked old fossils, seeing nothing, would not believe. No, First Mortgage, when those arcs start working to-morrow, you and I will be in a Hadley space ship up at the bottom of the layer, and as soon as the road has been opened, two of the lamps will cut off to allow us through. Then the battery will hold the road open while we pass out into space and return."

"Suppose we meet with Hadley's fate?" I demanded.

"We won't. Even if I am wrong—which is very unlikely—we won't meet with any such fate. We have two stern motors and four bow motors. As soon as we meet with the slightest resistance to our forward progress we will stop and have twice the power plus gravity to send us earthwards. There is no danger connected with the trip."

"All the same—" I began.

"All the same, you're going," he replied. "Man alive, think of the chance to make a world scoop for your paper! No other press man has the slightest inkling of my plan and even if they had, there isn't another space flyer in the world that I know of. If you don't want to go, I'll give some one else the chance, but I prefer you, for you know something of my work."

I thought rapidly for a moment. The chance was a unique one and one that half the press men in San Francisco would have given their shirts to get. I had had my doubts of the accuracy of Jim Carpenter's reasoning while I was away from him, but there was no resisting the dynamic personality of the man when in his presence.

"You win," I said with a laugh. "Your threat of offering some of my hated rivals a chance settled it."

"Good boy!" he exclaimed, pounding me on the back. "I knew you'd come. I had intended to take one of my assistants with me, but as soon as I knew you were here I decided that you were the man. There really ought to be a press representative
