He worked absorbedly for perhaps twenty minutes, his eyes intent. At the end of that time he had threads of unwound secondary wire stretched back and forth across a forked stick of dhil weed, and two small pieces of sheet iron twisted together in an extremely improbable manner. He connected the ends of the secondary wire to contacts in his tractor. He climbed into the tractor seat. He threw over the drive control.
The tractor lurched into motion. The Diesel wasn't running. But the tractor rolled comfortably as Lon drove it, the individual motors in the separate catawheels drawing power from a mere maze of wires across a forked stick—plus two pieces of sheet iron. There was plenty of power.
Lon drove the tractor the rest of the morning and all afternoon with a very peculiar expression on his face. He understood what he had done. Now that he had done it, it seemed the most obvious of expedients. He felt inclined to be incredulous that nobody had ever happened to think of this particular device before. But they very plainly hadn't. It was a source of all the electric power anybody could possibly want. The voltage would depend on the number of turns of copper wire around a suitably forked stick. The amperage would be whatever that voltage could put through whatever was hooked to it.
He no longer needed a new generator for his tractor. He had one.
He didn't even need a Diesel.
With adequate power—he'd been having to nurse the Diesel along, too, lately—Lon Simpson ran his tractor late into the twilight. He cultivated all the ground that urgently needed cultivation, and at least one field he hadn't hoped to get to before next week. But his expression was amazed. It is a very peculiar sensation to discover that one is a genius.
That night, in Cetopolis, he told Cathy all about it. It was a very warm night—an unusually warm night. They walked along the plank sidewalks of the little frontier town—as a new colony, Cetis Gamma Two was a frontier—and Lon talked extravagantly.
He had meant to explain painfully to Cathy that there was no use in their being romantic about each other. He'd expected to have to tell her bitterly that he was doomed to spend the rest of his life adding to the profits of the Cetis Gamma Trading Company, with all the laws of the human race holding him in peonage. He'd thought of some very elegant descriptions of the sort of people who'd worked out the system in force on Cetis Gamma Two.
