"Your names are Ruth and Ralph Gilraut? And you want permission to move into Housing Perimeter D?" It was merely a formality, since the information was in the folder. When the girl nodded, Stark placed a small check mark in the space beside her name. Then he turned to the Martian. The large, single red eye set deep in the Martian's smooth, green forehead above the two brown ones blinked twice before he answered. He spoke deliberately. "As is required of all Martians under the New System, I have taken the name of one of the early Earthlings to write and pronounce." The large red eye blinked again. "My wife would like to move into Housing Perimeter D. By regulation, I respect her wish." [Illustration] Stark placed a check mark by the Martian's name. He wiped the smudge of ink off his hand and said, "You both know, of course, that Perimeter D is reserved for couples who have intermarried and are about to have offspring?" The girl and the Martian nodded, and the girl passed Stark a medical report. Stark looked over the report and then made a notation on a small pink slip. He said, "This permit certifies that you are eligible to move from Perimeter E to Housing Perimeter D. It also certifies that your husband has no record as a troublemaker." Stark looked at the girl. "You understand that you may visit your friends in Perimeter E, but, by law, they will not be allowed to enter Perimeter D to visit you. And, of course, the new law clearly states that neither of you may visit Earthlings in Housing Perimeter A, B or C." The girl looked down at her hands. Her voice was almost inaudible. "My husband and I are familiar with the advantages and disadvantages listed under the section pertaining to intermarriage in the new law, Mr. Stark. Thank you." * * * * * Stark rose as they left. For a brief moment, he thought he had detected a sense of rebellion in their attitude. But that was not possible. The new law provided equality for all. And his department had been created to iron out relations between the two races--excepting complaints originated by troublemakers for the purpose of weakening the New System. In such cases, Investigations had stepped in and the Martian or Earthling troublemaker had been sent to the rare-earth mines. The reddish light filtering in through the quartz and lead wall of his office showed that it was almost time for the last bell. On the street below, shoppers were streaming out of the stores on their way to the various housing perimeters. Earthlings were climbing into their speedy little jet cars for the short trip to the recently modernized inner perimeters. Martians were waiting for the slower auto buses. The traffic problem had been solved, under the New System, by restricting the use of the Martian-built jet cars to persons living in the inner perimeters.
