Baker shook his head. "Three doctors from Callisto were here last month. They were as much at loss as I am. As for sending the men away, I may have to do that, but when I do, it means quits. Our company is chartered with Spacolonial, and you know what that means. Failure to produce during a period of thirty days or more, and you lose all rights." A visiphone bell sounded, and Baker walked across to the instrument. A man's face formed in the vision plate. Baker listened, said "Okay" and threw off the switch. "The entire crew of Shaft Four have gone out into the Baldric," he said slowly. There was a large map hanging on the wall back of Baker's desk. Grannie Annie walked across to it and began to study its markings. "Shaft Four is at the outer edge of the Baldric at a point where that corridor is at its widest," she said. Baker looked up. "That's right. We only began operations there a comparatively short time ago. Struck a rich vein of Acoustix that runs deep in. If that vein holds out, we'll double the output of _Interstellar Voice_, our rival, in a year." Grannie nodded. "I think you and I and Xartal had better take a run up there," she said. "But first I want to see your laboratory." There was no refusing her. Jimmy Baker led the way down to a lower level where a huge laboratory and experimental shop ran the length of the building. Grannie seized a light weight carry-case and began dropping articles into it. A pontocated glass lens, three or four Wellington radite bulbs, each with a spectroscopic filament, a small dynamo that would operate on a kite windlass, and a quantity of wire and other items. The kite car was brought out again, and the old woman, Baker and the Martian took their places in it. Then Jimmy waved, and the car began to roll down the ramp. * * * * * Not until they had vanished in the desert haze did I sense the loneliness of this outpost. With that loneliness came a sudden sense of foreboding. Had I been a fool to let Grannie go? I thought of her, an old woman who should be in a rocking chair, knitting socks. If anything happened to Annabella C. Flowers, I would never forgive myself and neither would her millions of readers. Ezra Karn and I went back into the office. The old prospector chuckled. "Dang human dynamo. Got more energy than a runaway comet." A connecting door on the far side of the office opened onto a long corridor which ended at a staircase. "Let's look around," I said. We passed down the corridor and climbed the staircase to the second floor. Here were the general offices of _Larynx Incorporated_, and through glass doors I could see clerks busy with counting machines and report tapes. In another chamber the extremely light Acoustix ore was being packed into big cases and marked for shipment. At the far end a door to a small room stood open. Inside a young man was tilted back in a swivel chair before a complicated instrument panel.
