with pride. There was a very long silence then. Nobody moved from their chosen vantage point. The hidden moon went down. At last Trace cleared his throat self-consciously. "I'd like to ask a question myself. Of you, Slough." After a slight pause, Slough said, "What is it, Trace?" "Well, you're a little too smart a geezer for reality, if you know what I mean. You figured those helmets for thought-radios, when it was a fantastic possibility that no normal man would have hit on so quick with so little to go on. Then you did things with the electronic device in that saucer that I couldn't have come up with in a coon's age." "I'm an engineer," said the tiny man. He chuckled.

"It's coming, they're hoping to do it," he said, and he clenched his teeth and took a firm grip on the girl, as though he wanted to hold her on the earth when it shot into the uncanny regions of sub-space. "Hold tight," he said, with no particular sense but a vast deal of emotion. "Hold tight, Jane baby." And Jane held him tightly. The saucers rose higher, dwindling in size; they reached the low cloud layer and passed into it, becoming hazy and then invisible. Twenty thousand spacecraft girdled the globe, linked
