And we went through compartments, too, in which were other great objects that had puzzled us so completely on Neptune, but whose purpose we saw now. These were the great flat metal containers stacked one upon the other, each a foot or so in depth, and each filled with black, green-shot soil. About them, as on Neptune, were set in the walls great white disks connected to generating apparatus of some kind, but here those generating mechanisms were humming with power, tended by many Neptunians, and there shot from the disks, over and through those great containers of soil, a ceaseless flood of pale violet light or force. And, even as we passed through those compartments, we saw strange and stocky pale-green plants bursting up from the soil of the containers, growing at incredible speed before our eyes, attaining a height of inches in but a minute or so! As these strange pale-green plants reached a height of a foot or so, there formed upon them masses of fruits or vegetables dead white in color, some being long and pod-like and others ball-shaped. And as these formed, the attendant Neptunians were swiftly turning off the violet force, pulling the fruit-laden little plants from the fine soil, and depositing them in low-wheeled containers, which were wheeled instantly away. Then from the framework that held the great soil-containers there sprayed out upon them fine whitish-green particles that I recognized as seed of some sort, that fell upon the soil and then were turned under it as some reversing mechanism turned over the soil in each container. Then the violet force from the wall-disks was turned on again, and in a moment another crop of pale-green plants was shooting up out of the containers!
