"It is an infallible technique—and one that we shall employ. Dr. Silvers will undertake to teach his mathematical lecturer in the approaches to the Legrandian Equations. He will speculate long and noisily on the geometry which potentially lies in this mathematical system. Dr. Carmen will elucidate at great length on the properties of the chain of chemicals he has been advised to abandon.

"Each of us has at least one line of research the Rykes would have us give up. That is the very thing we shall insist on having investigated. We shall teach them these things and prove Earthmen to be an unlearned, unteachable band of aborigines who refuse to pursue the single path to glory and light, but insist on following every devious byway and searching every darkness that lies beside the path.

"It ought to do the trick. I estimate it should not be more than a week before we are on our way back home, labeled by the Rykes as utterly hopeless material for their enlightenment."

The senators seemed momentarily appalled and speechless, but they recovered shortly and had a considerable amount of high flown oratory to distribute on the subject. The scientists, however, were comparatively quiet, but on their faces was a subdued glee that Hockley had to admit was little short of fiendish. It was composed, he thought, of all the gloating anticipations of all the schoolboys who had ever put a thumbtack on the teacher's chair.

Hockley was somewhat off in his prediction. It was actually a mere five days after the beginning of the Earthmen's campaign that the Rykes gave them up and put them firmly aboard a vessel bound for home. The Rykes were apologetic but firm in admitting they had made a sorry mistake, that Earthmen would have to go their own hopeless way while the Rykes led the rest of the Universe toward enlightenment and glory.

Hockley, Showalter, and Silvers watched the planet drop away beneath them. Hockley could not help feeling sympathetic toward the Rykes. "I wonder what will happen," he said slowly, "when they crash headlong into an impassable barrier on that beautiful, straight road of theirs. I wonder if they'll ever have enough guts to turn aside?"

"I doubt it," said Showalter. "They'll probably curl up and call it a day."

Silvers shook his head as if to ward off an oppressive vision. "That shouldn't be allowed to happen," he said. "They've got too much. They've achieved too much, in spite of their limitations. I wonder if there isn't some way we could help them?"
