 What seems to be a reason for many being sent to prison?
He was a captain of guards in Estates-General Correctional Institution—better known to its inmates as the Jug—and if he hadn't been able to detect the scent of trouble brewing a cell-block away, he would never have survived to reach his captaincy. And, what was more important, why she couldn't adjust herself to it, now that she was in. It said in the Civil Service Guide to Prison Administration : "Detainees will be permitted to speak in their own behalf in disciplinary proceedings." From the born mechanic and the man with the gift of gab, society evolved to the point of smaller contact and less communication between the specializations, until now they could understand each other on only the most basic physical necessities—and not even always then. The ultimate should be the complete segregation of each specialization—social and genetic measures to make them breed true, because the unspecialized man is an uncivilized man, or at any rate he does not advance civilization. And letting the specializations mix would produce genetic undesirables: clerk-laborer or Professional-GI misfits, for example, being only half specialized, would be good at no specialization. And the basis of this specialization society was: "The aptitude groups are the true races of mankind." Every prison has its Greensleeves—sometimes they are called by different names. When you're in it, you don't much care what it is called; it is a place for punishment. And punishment is what you get. Block O in Estates-General Correctional Institution was the disciplinary block, and because of the green straitjackets its inhabitants wore, it was called the Greensleeves. She was in a detachment of three unfortunates like herself, convoyed by an irritable guard, climbing the steel steps toward Block O from the floor below, when she heard the yelling. "Owoo-o-o," screamed Sauer from one end of the cell block and "Yow-w-w!" shrieked Flock at the other. The two guards turned to see what was coming in as the three new candidates for the Greensleeves slumped to a stop at the head of the stairs. The outside guard said sourly: "A woman, for God's sake. The outside guard pulled the switch that turned on the tanglefoot electronic fields that swamped the floor of the block corridor and of each individual cell. While the fields were on, you could ignore the prisoners—they simply could not move fast enough, against the electronic drag of the field, to do any harm.
