He said nothing, however, to anyone but strode over and sat beside Hockley, who was alone at the moment smoking the next to last of his Earthside cigars. Hockley felt the smouldering turmoil inside the mathematician. He extended his final cigar. Silvers brushed it away.

"The last one," said Hockley mildly. "In spite of all their abilities the Ryke imitations are somewhat less than natural."

Silvers turned slowly to face Hockley. "I presented them with the Legrandian Equations today," he said. "I expected to get a straightforward answer to a perfectly legitimate scientific question. That is what we were led to expect, was it not?"

Hockley nodded. "That's my impression. Did you get something less than a straightforward answer?"

The mathematician exhaled noisily. "The Legrandian Equations will lead to a geometry as revolutionary as Riemann's was in his day. But I was told by the Rykes that I 'should dismiss it from all further consideration. It does not lead to any profitable mathematical development.'"

Hockley felt that his heart most certainly skipped a beat, but he managed to keep his voice steady, and sympathetic. "That's too bad. I know what high hopes you had. I suppose you will give up work on the Equations now?"

"I will not!" Silvers exclaimed loudly. Nearby groups who had returned hesitantly to their own conversations now stared at him again. But abruptly he changed his tone and looked almost pleadingly at Hockley. "I don't understand it. Why should they say such a thing? It appears to be one of the most profitable avenues of exploration I have encountered in my whole career. And the Rykes brush it aside!"

"What did you say when they told you to give it up?"

"I said I wanted to know where the development would lead. I said it had been indicated that we could have an answer to any scientific problem within the range of their abilities, and certainly this is, from what I've seen.
