In front of the generators' recording dials and switches was suspended a metal chair like that of the control-operator, while between those two was a third chair before which, on the control-panel, were ranged the instruments recording the space-flier's conditions of flight. There was a space-speed indicator, working by means of ether-drift, a set of dials that accurately recorded the gravitational pull of celestial bodies in all directions, inside and outside temperature recorders, inside and outside air-testers, and beside others the controls of a number of the necessary mechanisms attached at different points inside the hollow faceted ball of the flier. Among these were the controls of the flier's air-renovator, which automatically removed the carbon-dioxide from the flier's breathed air by atomic dissociation and replaced it with oxygen from the compact tanks of compressed liquid-oxygen; the controls of the heating-mechanism, which beside its own heating coils was to utilize the heat of the sun on the flier's side in space; and the control of the hooded lights set above the flier's control-panel and mechanisms. To the right of the control-operator's chair, too, there was a fourth similar chair before which were ranged on the control-panel a compact but extremely efficient battery of astronomical instruments. There was a ten-inch refracting telescope, its lens set directly in the big hexagonal window over the control-panel, the tube of the telescope, thanks to the new "re-reflecting" principle, being but a score or so of inches in length. There was also a small but efficient spectroscope similarly mounted, a micrometric apparatus for accurate measurements of celestial objects, and a shielded bolometer for ascertaining the radiated heat of any celestial body. These four metal chairs, suspended there in front of the long control-panel and with the big hexagonal window before and above them, were mounted all upon special shock-absorbing tubes of pneumatic design which would enable us to withstand the pressure of our flier's acceleration upon starting, and the pressure also of its deceleration upon slowing and stopping. Seated in them, we would be able to look forth over the space-flier's controls into the void before us, and since gravitation would be lacking in the flier, once out in space, metal straps across them would hold us in them. Here and there among the mechanisms that lined the ball-like flier's interior, too, were hand-grips by which we could float without harm among the mechanisms and equipment, while the metal bunks attached at one point to the flier's interior were provided with metal straps to hold us in them during sleep. * * * * *
