"None. But she was aware of them. On her face was stark terror--as we had seen it from here, Father, a month before. I noticed that the giant's forward step had nearly been completed--and the climbing dwarf was holding tightly to her sandal cord." Brett gazed at me inquiringly but I shook my head. "That's all I have to ask," I said. "Go ahead, Brett. You were telling us about how you started the size-change----" Dr. Gryce put in. "I think you had best proceed, Brett. And then if there is anything Frank does not understand, we can stop and make it clear." He nodded, but for a moment he hesitated. "I flung over the switch to start our growth," he said slowly. "It was the beginning of all those strangely weird experiences which followed now one upon the other. Frightening at first. . . ." IV He paused briefly, then went on: "Our first sensation was one of shock--a reeling of the senses. But it was not severe--it passed almost at once. We found ourselves clinging there to the instrument table. To me the room seemed swaying dizzily. My forehead was damp with cold moisture; a nausea possessed me. I was oppressed; the air of the room was heavy to breathe." "The air was snapping with the current," said Martt. "I could see it, and feel it tingling against my face. And it was heavy to breathe, as Brett says." Brett resumed: "But we felt better after a moment. I saw the change first on the dials. The pointer of the lowest unit dial of the size series was slowly but visibly moving. I watched as it crept from 1 to 2. We had doubled in size. I gazed about the room. It was unchanged; and now as my body rapidly adjusted itself to the new conditions, I began to feel almost normal. Except a queer whirring in my head, and the nausea which persisted for perhaps an hour, I felt no evidence of the growth. The room, the vehicle was untrembling. No slightest evidence within the vehicle of the size-change going on--except the creeping pointer of the lowest dial. It was moving faster; it had reached 10. The pointer of the dial beside it--registering in units of a hundred--now seemed stirring." Brett gazed at us earnestly. "I want to make myself absolutely clear. We were then--I suppose a minute or so had elapsed--we were ten times our original size----" "Much faster than the vehicle grew in the garden," I exclaimed. "Yes. I had chanced the possibility of severe shock and thrown the lever at once to a quarter strength. Martt and Frannie, in the garden, had put it on only to the one-hundredth part of its power. At all intensities, the growth, you understand, constantly accelerates. At unit 10, which we reached in possibly the first minute, we were ten times our starting size--that is, for earth measurements, our vehicle from base to tower-top was then one-tenth of a mile. But soon the pointer had passed 50. And then 100--and the pointer of the hundred-unit dial had crept to 1.
