"No! I want to talk to him, after so long. These years when I thought he was dead."

"Scheming. You think, my little Babs, that he has the drugs? I am not so much a fool. He makes them. He can do that, and the last secret reactions only he can perform. He iss stubborn. Never would he tell me that one reaction. But he makes no drugs complete, only when I am here."

"No, Dr. Polter! I want only to be with him."

The old man's broken voice floated up to us. "You will not harm her, Polter?"

"No. Fear nothing. But you no longer rebel?"

"I will do what you tell me." The tones carried hopeless resignation, years of being beaten down, rebelling--but now this last blow vanquished him. Then he spoke again, with a sudden strange fire.

"Even for the life of my daughter, I will not make your drugs, Polter, if you mean to harm our Earth."

The golden cage room swooped as Polter sat down. "Hah! Now we bargain.

What do you care what I do to your world? You never will see it again.

I can lie to you. My plans--"

"I do care."

"Well, I will tell you, Kent. I am good natured now. Why should I not be, with my dear little Babs? I tell you. I am done with the Earth world. It iss so much nicer here. My friends, they haf a good time always. We like this little atom realm. I am going out once more. I must hide the little piece of golden quartz so no harm will come to it."

Polter was evidently in a high good humor. His voice fell to an intimate tone of comradeship; but still I could not mistake the irony of it.

"You listen to me, Kent. There was a time, years ago, when we were good friends. You liked your young a.s.sistant, the hunchback Polter.

Iss it not so? Then why should we quarrel now? I am gifing up the Earth world. I wanted of it only the little Babs.... You look at me so strange! You do not speak."

"There is nothing to say," retorted Dr. Kent wearily.

"Then you listen. I haf much gold above, in Quebec. You know that. So very simple to take it out of our atom, grow large with it, to what we call up there the size of a hundred feet. I haf a place, a room, secluded from prying eyes under a dome-roof. I become very tall, holding a piece of gold. It is large when I am a hundred feet tall. So I haf collected much gold. They think I own a mine. I haf a smelter and my gold quartz I make into ingots, refined to the standard purity.

So simple, and I am a rich man.

"But gold does not bring happiness, my friend Kent." He chuckled ironically at his use of the plat.i.tude. "There is more in life than the ownership of gold. You ask my plans. I haf Babs, now. I am gifing up our Earth world. The mysterious man they know as Frank Rascor will vanish. I will hide our little fragment of quartz. No one up there will even try to find it. Then I come down here, with Babs, and we will haf so nice a little government and rule this world. No more of the drugs then will be needed, Kent. When you die, let the secret die with you."

Again Polter's voice turned ingratiating, even more so than before.

"We will be friends, Kent. Our little Babs will lof me; why should she not? You will tell her--advise her--and we will all three be very happy."

Dr. Kent said abruptly, "Then leave her with me now. That was her request, a moment ago. If you expect to treat her kindly, then why not--"

"I do! I do! But not now. I cannot spare her now. I am very busy, but I must take her with me."

Babs had been silent, clinging to the bars of our cage. She called:

"Why? I ask you to put this cage down."

"Not now, little bird."

"And let me be with my father."

It struck a pang through me. Babs was scheming, but not the way Polter thought. She wanted the cage put on the floor, herself out, and a chance for me to escape. I had not yet told her of my miserable stupidity in losing the vial.

Polter was repeating. "No, little bird. Presently; not now. I may take you out with me, my last trip out. I want to talk with you in a normal size when I haf time."

Our room swooped as he stood up. "You think over what I haf said, Kent. You get ready now to make the fresh drugs I will need to bring down all my men from the outer world. They will all be glad to come, or, if not--well, we can easily kill those who refuse. You make the drugs. I need plenty. Will you?"

"Yes."

"That iss good. I come back soon and gif you the catalyst for that last reaction. Will you be ready?"

"Yes."

The blur outside our bars swung with a dizzying whirl as Polter turned and left the room, locking its door after him with a reverberating clank.

Left alone in his laboratory, Dr. Kent began his preparations for making a fresh supply of the drugs. This room, with two smaller ones adjoining, was at once his workshop and his prison. He stood at his shelves, selecting the basic chemicals. He could not complete the final compounds. The catalyst which was necessary to the final reaction would be brought to him by Polter.

How long he worked there with his thoughts in a whirl at seeing Babs, he did not know. His movements were automatic; he had done all this so many times before. His mind was confused, and he was trembling from head to foot, an old, queerly, unnaturally old man now--unnerved. His shaking fingers could hardly hold the test tubes.

His thoughts were flying. Babs was here, come down from the world above. It was disaster--the thing he had feared all these years.

He suddenly heard a voice.

"Father!"

And again: "Father!" A tiny voice, down by his shoe-tops. Two small figures were there on the floor beside him. They were both panting, winded by running. They were enlarging; they had come from a smaller size.

It was Alan and Glora, who had followed Polter from the boat, diminished again, and come running through the tiny crack under the metal door of the laboratory.

They grew to a foot in size, down by Dr. Kent's legs. He was too unnerved; he sat in a chair while Alan swiftly told him what had happened. Babs was in the golden cage. Dr. Kent knew that; but none of them knew what had happened to me.

"We must make you small, Father. We have the drugs, here with us."

"Yes! Yes, Alan. How much have you? Show me. Oh, my boy, that you are here--and Babs--"

"Don't you worry, we'll get away from him."

Glora and Alan had almost reached Dr. Kent's size before their excited fingers could get out the vials. They took some of the diminishing drug to check their growth. Alan handed his father a black vial.

"Yes, lad--"

"No! Wait, Father! That's the wrong drug. This other--"
