This had left Ross and Art to carry out numerous chores for the enterprise, then to make their own way to New Mexico to open up the camp.

The warning to follow the power line had been necessary; the boys found the desert inside pock-marked by high explosive and criss-crossed with tracks, one as good as another, carved years before by truck and tank and mobile carrier. The cabin itself they found to be inside a one-strand corral a quarter of a mile wide and over a mile long. Several hundred yards beyond the corral and stretching away for miles toward the horizon was an expanse which looked like a green, rippling lake—the glassy crater of the atom bomb test of 1951, the UN's Doomsday Bomb.

Neither the cabin nor the piled-up freight could hold their attention until they had looked at it. Ross drove the car to the far side of the enclosure and they stared.

Art gave a low respectful whistle. "How would you like to have been under that?" Ross inquired in a hushed voice.

"Not any place in the same county—or the next county. How would you like to be in a city when one of those things goes off?"

Ross shook his head. "I want to zig when it zags. Art, they better never have to drop another one, except in practice. If they ever start lobbing those things around, it ‘ud be the end of civilization."

"They won't," Art assured him. "What d'you think the UN police is for? Wars are out. Everybody knows that."

"You know it and I know it. But I wonder if everybody knows it?"

"It'll be just too bad if they don't."

"Yeah—too bad for us."

Art climbed out of the car. "I wonder if we can get down to it?

"Well, don't try. We'll find out later."

"There can't be any duds in the crater or anywhere in the area—not after that."

"Don't forget our friend that the buzzards ate. Duds that weren't exposed to the direct blast might not go off. This bomb was set off about five miles up."

"Huh? I thought-"

"You were thinking about the test down in Chihuahua. That was a ground job. Come on. We got work to do." He trod on the starter.

The cabin was pre-fab, moved in after the atom bomb test to house the radioactivity observers. It had not been used since and looked it.

"Whew! What a mess," Art remarked. "We should have brought a tent."

"It'll be all right when we get it fixed up. Did you see kerosene in that stuff outside?"

"Two drums of it."

"Okay. I'll see if I can make this stove work. I could use some lunch." The cabin was suitable, although dirty. It had drilled well; the water was good, although it had a strange taste. There were six rough bunks needing only bedding rolls. The kitchen was the end of the room, the dining room a large pine table, but there were shelves, hooks on the walls, windows, a tight roof overhead. The stove worked well, even though it was smelly; Ross produced scrambled eggs, coffee, bread and butter, German-fried potatoes, and a bakery apple pie with only minor burns and mishaps.

It took all day to clean the cabin, unload the car, and uncrate what they needed at once. By the time they finished supper, prepared this time by Art, they were glad to crawl into their sacks. Ross was snoring gently before Art closed his eyes. Between Ross's snores and the mournful howls of distant coyotes Art was considering putting plugs in his ears, when the morning sun woke him up.

"Get up, Ross!"

"Huh? What? Wassamatter?"

"Show a leg. We're burning daylight."

"I'm tired," Ross answered as he snuggled back into the bedding. "I think I'll have breakfast in bed."

"You and your six brothers. Up you come—today we pour the foundation for the shop."

"That's right." Ross crawled regretfully out of bed. "Wonderful weather—I think I'll take a sun bath."

"I think you'll get breakfast, while I mark out the job."

"Okay, Simon Legree."

The machine shop was a sheet metal and stringer affair, to be assembled. They mixed the cement with the sandy soil of the desert, which gave them a concrete good enough for a temporary building. It was necessary to uncrate the power tools and measure them before the fastening bolts could be imbedded in the concrete. Ross watched as Art placed the last bolt. "You sure we got ‘em all?"

"Sure. Grinder, mill, lathe-" He ticked them off. "Drill press, both saws-"

They had the basic tools needed for almost any work. Then they placed bolts for the structure itself, matching the holes in the metal sills to the bolts as they set them in the wet concrete. By nightfall they had sections of the building laid out, each opposite its place, ready for assembly. "Do you think the power line will carry the load?" Art said anxiously, as they knocked off.

Ross shrugged. "We won't be running all the tools at once. Quit worrying, or we'll never get to the moon. We've got to wash dishes before we can get supper."

By Saturday the tools had been hooked up and tested, and Art had rewound one of the motors. The small mountain of gear had been stowed and the cabin was clean and reasonably orderly. They discovered in unpacking cases that several had been broken open, but nothing seemed to have been hurt. Ross was inclined to dismiss the matter, but Art was worried. His precious radio and electronic equipment had been gotten at.

"Quit fretting," Ross advised him. "Tell Doc about it when he comes. The stuff was insured."

"It was insured in transit," Art pointed out. "By the way, when do you think they will get here?"

"I can't say," Ross answered. "If they come by train, it might be Tuesday or later. If they fly to Albuquerque and take the bus, it might be tomorrow—what was that?" He glanced up.

"Where?" asked Art.

"There. Over there, to your left. Rocket."

"So it is! It must be a military job; we're off the commercial routes. Hey, he's turned on his nose jets!"

"He's going to land. He's going to land here!"

"You don't suppose?"

"I don't know. I thought—there he comes! It can't-" His words were smothered when the thunderous, express-train roar reached them, as the rocket decelerated. Before the braking jets had been applied, it was traveling ahead of its own din, and had been, for them, as silent as thought. The pilot put it down smoothly not more than five hundred yards from them, with a last blast of the nose and belly jets which killed it neatly.

They began to run.

As they panted up to the sleek, gray sides of the craft, the door forward of the stub wings opened and a tall figure jumped down, followed at once by a smaller man.

"Doc! Morrie!"

"Hi, sports!" Cargraves yelled. "Well, we made it. Is lunch ready?"

Morrie was holding himself straight, almost popping with repressed emotion.

"I made the landing," he announced.

"You did?" Art seemed incredulous.

"Sure. Why not? I got my license. Want to see it?"

"‘Hot Pilot Abrams,' it says here," Ross alleged, as they examined the document. "But why didn't you put some glide on it? You practically set her down on her jets."

"Oh, I was practicing for the moon landing."

"You were, huh? Well, Doc makes the moon landing or I guarantee I don't go."

Cargraves interrupted the kidding. "Take it easy. Neither one of us will

try an airless landing."

Morrie looked startled. Ross said, "Then who-"

"Art will make the moon landing."

Art gulped and said, "Who? Me?"

"In a way. It will have to be a radar landing; we can't risk a crack-up on anything as hard as an all jet landing when there is no way to walk home. Art will have to modify the circuits to let the robot-pilot do it. But Morrie will be the stand-by," he went on, seeing the look on Morrie's face. "Morrie's reaction time is better than mine. I'm getting old. Now how about lunch? I want to change clothes and get to work."

Morrie was dressed in a pilot's coverall, but Cargraves was wearing his best business suit. Art looked him over. "How come the zoot suit, Uncle? You don't look like you expected to come by rocket. For that matter, I thought the ship was going to be ferried out?"
