David Adam Smith was a small man. With his cloak and large hearing aid and long thin face, he always made me think of a grounded bird. He came hopping over the tiles with short quick steps, peering at the specimens and at me. "Go out again tomorrow," he snapped. "I want some copper chloride specimens." "Would you like me to drive the bubble-dancer to transportation?" I asked. "Who? Oh, that girl. No, Morris, I sent her away. You'll have to confine yourself to the curriculum, I fear, hig, hig, hig." That was odd because I thought I was about the only person in the Institute who could drive a land-vehicle. The roads outside were built over and everyone used jets. But I wouldn't have put it past him to have made the girl walk out of the desert, or to have sent her in his own space-glass jet, depending on how he assessed her publicity value. I forgot about it while carting off the specimens. * * * * * Dimples was pretty, a trifle Venusian in her plumpness but very intelligent. We met by the fountain in one of the smaller courtyards. John Thay, she told me, had volunteered to remain but I was to collect the other two from the boundary. "They won't be too heavy will they, Morry?" "Three or four pounds. Living substance modifies in some way, or it may be the effect of being in solid solution in an expanded lattice." "But you can take them down to half an inch?" "I hope so." We arranged to meet just before the afternoon session the next day, so that Lee and Burns would be sent off in the afternoon stellar-reporters with as little delay as possible. They were there at the boundary when I drove up the next day. Their converter worked. They were embedded neatly in the quartz crystals. I took them in, handed them to Dimples and that was that. Neither Burns nor his stellar-reporter returned. We never knew what happened. Some of the little rockets did fail. Not many. But it was his misfortune to be in one that did not come back. Lee White did return safely, and was sent out again to his chosen planet. We began to handle crystals regularly. John sent each emigrant with a miniature converter and controls, which I reduced on the edge of the desert and handed to Dimples, who inserted the crystal and the miniature converter into the next stellar-reporter due for Lee's planet. He was accumulating heaps of converters on his planet, but we could not risk leaving an emigrant helpless in his crystal when the stellar-reporter dumped it on the far planet. This way they rolled out together on arrival. We must have sent out two hundred emigrants of all kinds, for John was sending in a mixed selection to give the far planet every chance of a successful settlement, when Dimples met me at the fountain and cried--moistly--all over my arm. "Oh, Morry," she wept. "He's found out." "He," obviously, was David Adam Smith. "How do you know? What did he say?"
