Along with Kingman was a small battery-powered duplicator, and a set of recordings. The duplicator produced fresh air as needed, water, food, and even books, games, and puzzles for solitary entertainment. Waste material went into the matter bank, proving the earlier statements that with a well-equipped duplicator and a set of recordings, any man can establish a completely closed system that will be valid for any length of time desired. When the ship landed, Kingman tossed all the loose material into the duplicator and reduced it to nonhomogeneous matter in the matter bank. Then he turned the duplicator-beam against the side-wall of the huge box and watched the side-wall disappear into the machine. He stepped out through the opening, which was calculated to miss the concealed plates of identium installed to prevent just this very thing. Kingman, of course, had planned it that way. Once outside, Kingman set the duplicator on the deck between other cases and snapped the switch. The scanner beam produced books from Kingman's own library which he packed in the case. Then by reversing the direction of depth scan without changing the vertical or horizontal travel, Kingman effected a completed reversal of the restoration. The side of the packing case was re-established from the inside out, from the original recording which, of course, was made from the other side. It re-formed perfectly, leaving no seam. Kingman went down an unused shaft to the bottom of the ship, where he drilled down with the duplicator through the bottom of the ship where it stood upon the Landing Stage. Down through the stage he went and into a between-deck volume that was filled with girders. He re-set the duplicator and replaced landing stage and the ship's hull. By the time that the party had adjourned to Joe's, Mark Kingman was high in the Relay Station, near the center line and a full mile and a half from the Landing Stage. He was not far from the vast room that once contained a lush growth of Martin Sawgrass, used before the advent of the duplicator, for the purification of the atmosphere in Venus Equilateral. He was reasonably safe. He knew that the former vast storages of food and supply were no longer present, and that being the case, few people would be coming up to this out of the way place almost a third of a mile above the outer radius of the station where the personnel of Venus Equilateral lived and worked. He started his duplicator and produced a newly charged battery first. He tossed the old one into the matter bank. He'd have preferred a solar energy tube, but he was not too certain of Sol's position from there and so he had to forego that. Then he used the duplicator to produce a larger duplicator, and that duplicator to make a truly vast one. The smaller numbers he shoved into the larger one. From the huge duplicator, Kingman made great energy-beam tubes and the equipment to run them. Taking his time, Kingman set them up and adjusted them carefully.
