and grudgingly given, but he could not deny they had overlooked nothing. Indeed, it frightened him. If they saw his character so clearly part of the way, what was to prevent them seeing it all the way?
Could he deceive his employers as well as those about him?
Winchester learned that he was to go to the great Interplanetary Natural History Museum, a place where living plants and animals of the planets, satellites and asteroids were kept. He was to be the Vice-Curator — one of many — but expected to know little except the plant life of Mars.
Actually, he was to be under instruction for some special work, to be assigned later by the Inner Council of Controlling Scientists. What that body was, he was not told.
But when he came to the envelope marked "Secret Instructions," he was startled at their brevity, so in contrast with the elaborate preparations of his personality. There was but a single sentence.
Be alert to discover disloyal subjects; report daily.
He slammed the folder shut. It was a thing that would require much study. It had required many hours to read through it once, and he marveled that it could have been compiled in so short a time. The only explanation could be that they had many such dossiers, prepared in blank.
Winchester reported to his chief at last that he was ready. He wore the maroon robe a guard had brought him. It was the symbol of his rank and branch of work.
The man in green looked up at him as if it had been less than an hour since he stepped out of the room. Actually, it had been a full week, Earth time.
"You will leave by a secret subway to Grand Central, and there you will be mixed with the incoming passengers from a Moon-Mars express coming in shortly. Your baggage is on board. Flunkies from the museum will meet you and take you to your destination.
"It is arranged that you will be assigned laboratory H-three in the Botanical Building. In one corner of it is a writing desk, and beside it a small incinerator. Each night you will sit there and write your report of the day.
"Head each sheet Eight-RYF, sign each sheet Three-eleven-RYF. The latter is your personal number. Upon completing a sheet, feed it at once to the incinerator, and begin the next. When your report is finished, operate the small mill at the base of the incinerator.
"That will reduce the paper ashes to powder. Dissolve the powder in the liquid marked 'K', which you will find at hand. Pour the solution down the drain. Is that clear?"
"Yes."
"Very well."
The chief tapped a bell. A special guard appeared.
"Mars — incoming — twenty-two: thirty-four today. Take him away."
Winchester followed the guard through an intricate maze of secret panels and hatches. They eventually came to a tunnel of small bore, which had rails laid at one hundred and twenty-degree intervals about its perimeter. The guard pressed a spot in the wall, and in a moment a small car slid to a stop before them. They got in.
A reverse process brought them to the end of a blind passage. The guard put his eye to a small lens set in the wall.
"The Martian passengers have just disembarked," he said in a low voice. "As soon as the last of them has passed, step out and follow them. People will meet you below."
There was a nudge, and the false wall slid sideward. Winchester eased himself through the slit afforded and found himself on a steep ramp. He could hear the tramp of feet below, as of a considerable crowd going down. He turned at once and descended after them.
At the bottom of the ramp he saw other passengers being greeted. He noted their behavior and looked about him. He had not been told how he was to recognize the museum flunkies. Then he observed three slaves in the domestic gray, but with maroon hems on their kilts. They were on their chests and knees, bumping their faces on the pavement toward him. He strode over to them.
"Arise, slaves, and do your duty."
It hurt him to use the words, but that was the formula used by those who had preceded him, and he thought best not to depart from it. The three servants rose, and two disappeared into the crowd. Winchester supposed they were going after his baggage.
"This way, master," the third said.
The passage to the museum was made in a small rocket-car, operated by technicians. They did not perform the kow-tow, but bowed deeply as Winchester appeared.
"There it is, Worthy," said the pilot, causing the machine to hover over a huge crystal dome on the anti-Earth side.
The "Worthy" came as a little shock, too, though the book had told Winchester scientists of rank rated it.
"The big dome covers all," the pilot explained. "Beneath are many small craters, each with its own dome. One for Venus, one for Mars, and so on. It's the universe in a thimble, as we call it."
"Thanks," said Winchester, looking down.
Suddenly he felt oppressed by the magnitude of the task he had undertaken. He knew so little. There was so much to do. And danger lurked everywhere. He had already seen how one impulsive, unconsidered act had cost the lives of dozens. What was ahead?
"Land, please," he ordered. "I am anxious to see it."
CHAPTER XII
New Beginnings
The establishment beneath the iridescent dome was amazing indeed. It was, as the pilot had said, a universe in a thimble, though the thimble was a sizable one — fifty miles across and several deep.
Colorful villas nestled at the foot of the cliffs among groves of terrestrial trees, while a grassy plain, criss-crossed with roads, formed the crater bottom. A score or more of lesser cones stuck their heads up into the Earthly atmosphere, but it could be seen that they were covered with domes of their own and had entrance portals cut into their flanks.
Despite the genial artificial climate of the museum as a whole, some of the small craters were perpetually covered with frost and patches of ice, indicating they were severely refrigerated within. Those were the ones holding the exhibits from dim Uranus and Neptune.
A staff car took Winchester to a long low building near the Crater of Venus. There he presented his passport, his orders and other credentials to a gimlet-eyed police official. After answering a few perfunctory questions, he was sent into an adjoining office to meet his new superior, the Curator-in-Chief. He was a sad-visaged, weary-looking man of about sixty, and very gaunt.
"Your work," he said, "will be adapting other planet life-forms to Earthly conditions. Some can be made to live, some not. It is a matter of chemistry and temperature, largely — sometimes glands. You will learn about this as you go along. You will be quartered in the Botanical Section, where they will tell you more."
The chief dismissed Winchester with a nod of his head.
The suite to which the American was assigned was H-3, as had been foretold him. It contained not only a small, well-equipped laboratory, but living rooms. The comfort and seeming privacy of the apartment astonished Winchester, for his experience until then had been that all of the conquered race were treated like dogs. He was to learn in the next few days that there were many exceptions, particularly among the scientist class.
Presently the instructor to whom Winchester was assigned took him to a large greenhouse, situated just outside one of the smaller craters.
"Take it easy in here," he was advised. "The air is thin, and contains much less oxygen than you are used to. We are trying to wean some Ionian Harps for transplantation to the Khan's villa in America."
The instructor led the way to a row of purplish plants that resembled kettledrums. As they appeared, Winchester observed that they gave off a sweet, doleful, humming sound through the vibration of a number
