"Because you are alien. You are impartially alien. Though you have friends on Telfu, they are few, and in your secret mind you class us all as 'Telfan' and forget about sub-classifications. This experimentation is just that, to you, and we are the subjects. Therefore when you select one hundred victims out of a district, we get a perfect, impartial selection; a true cross-section of the district." "Any of you could do that." "No. We'd be biased by our knowledge of who is important, who is the sicker, who is young and who is old. And, though it may seem strange to you, you have absolutely no idea of beauty. Therefore you are impartial among the ugly and the beautiful." "So what?" "In experimentation on humans, we are inclined to pick those of less value to the community. We pick the lame and the halt and the ugly. We are inclined to pick those who are likely not to live anyway, and this biases our selection. Come, let's get going." "O.K. Lead on." * * * * * Three hours later, and still without sleep, Sandra strode up the line of Telfans and pointed out one after the other. Those selected followed silently to the auditorium in the center of the village and seated themselves. They looked neither happy nor regretful, but rather a resignation was upon them. Sandra said: "Is this the best place you could pick?" "Sorry," smiled Theodi. "I didn't know it made any difference." "I suppose it is good from a functional standpoint," said Sandra. "Being on the stage permits them to pass before us from one side to the other. It is the only clear place in the auditorium in which to work, and as far as I could see, there isn't any other suitable place in town. But being on the stage sort of makes me ... oh, come on. I'm just tired, I guess. Where's the pills?" "No pills on this deal," said Theodi, opening a case and removing a set of large hypodermics. "This goes into the vein. Right in the main line. You'll have to help." "Me? Look, Theodi, I don't feel well enough to go shoving needles into people." Theodi looked up sharply. Her brash-sounding statement was made in a hard voice in spite of its humanitarian and pleading sound. Sandrake, to Theodi's opinion, was really feeling ill. "It must be done," he said simply. "You fill and hand them to me." Sandra took the first hypo, inserted it into the disinfectant, and then filled it from an ampule. She handed it to Theodi and watched him with fascination as he took the first Telfan in line and thrust the needle into his arm. It went in and in, and Theodi felt around with the needle-point until he found the vein, and then he emptied the cylinder. "Next!" he called, and so on until the hundred had been inoculated. "Now," said Theodi, "we'll proceed to Dorana and do likewise." Sandra was silent all the way to the next village, and as she started down the line of people, picking them out one by one, her face began to whiten. Halfway through, Sandra stopped.
