There were two--no, three dark shapes coming toward the box, moving swiftly through the green and chartreuse vapors. They undulated on two pairs of stubby legs set fore and aft under a flexible lower body. Their upper bodies, carried erect, were rather bulbous and tall, with well-defined heads and two sets of specialized arms, the lower ones thick and powerful for heavy work, the upper ones as delicate as an engraver's fine tools. Their skin was a glossy black, almost like patent leather. They wore neat harnesses of what looked like metal webbing in the way of dress, and on the breast strap each one carried an insigne. "Ship's officers," Durham guessed. "Probably one of them's the captain." "They're horrible," said Susan. She backed away from the window until the end of the bunk caught her behind the knees and she sat down. Durham laughed. "Fine pair of cosmopolites we are. We're used to the idea of non-humanoids. There are a lot of them on The Hub, but they're mostly segregated by necessity, so we practically never really see any. But now we're the ones who have to be segregated. And the reality is quite another thing from the idea, isn't it?" * * * * * He backed away himself, a step or two, until shame made him stop. The three non-humanoids came and looked with large iridescent eyes, through the window. Their oddly shaped mouths moved rapidly, so he knew that they were talking, and their slender upper arms were as mobile and expressive as the hands of so many girls at a sorority tea. Then one of them turned and did something to the wall of the box, and suddenly Durham could hear them clearly. There was a speaker device beside the window. Durham sprang at it. "Can you hear me? Can you hear me out there? Listen, you have no right to do this, you've got to take us back! Miss Hawtree is the daughter of--" "Mr. Durham." The voice was unhuman but strong, and the esperanto it spoke was perfectly understandable. "Please calm yourself and listen to what I have to say. I appreciate your feelings--" "Hah!" "--but there is nothing I can do about it. I have my orders, and I can assure you--" "From Jubb?" "You'll be fully informed when you reach Senya Dik. Meanwhile, I can assure you that no harm will come to you, now or later. So please put your fears at rest. A little patience--" Susan had leaped up. Now she flung herself upon the speaker mike. "What about me?" "Your presence was unexpected, and I fear it's going to be rather difficult for you both. But you must make the best of it. In regard to air and water, I must caution you that the supply will hardly be adequate for you both unless you are extremely careful." This had not occurred to Susan before. "You mean--" "I mean that you must use no more water than is absolutely necessary for drinking and preparing your food. The food you must share between you, on half rations. As for the air--" "Yes," said Durham. "What about the air?"
