Now, shiny new buildings replaced the ancient houses which had endured for as much as a thousand years. A gleaming bridge linked Dover and Calais; elsewhere, the rivers of Europe were bridged frequently, providing easy access between the many states of the Federation of Europe. Here, there, monuments of the past remained—the Eiffel Tower, absurdly dwarfed by the vast buildings around it, still reared its spidery self in Paris, and Notre Dame still remained as well. But the rest of Paris, the ancient city Alan had read so much of—that had long since been swept under by the advancing centuries. Buildings did not endure forever.

In Zurich he visited the Lexman Institute for Space Travel, a magnificent group of buildings erected on the royalties from the Lexman Spacedrive. A radiant statue sixty feet high was the monument to Alexander Lexman, who in 2337 had first put the stars within the reach of man.

Alan succeeded in getting an interview with the current head of the Institute, but it was anything but a satisfactory meeting. It was held in an office ringed with mementoes of the epoch-making test flight of 2338.

"I'm interested in the work of James H. Cavour," Alan said almost immediately—and from the bleak expression that appeared on the scientist's face, he knew he had made a grave mistake.

"Cavour is as far from Lexman as possible, my friend. Cavour was a dreamer; Lexman, a doer."

"Lexman succeeded—but how do you know Cavour didn't succeed as well?"

"Because, my young friend, faster-than-light travel is flatly impossible. A dream. A delusion."

"You mean that there's no faster-than-light research being carried on here?"

"The terms of our charter, set down by Alexander Lexman himself, specify that we are to work toward improvements in the technique of space travel. It said nothing about fantasies and daydreams. No—ah—hyperdrive research is taking place at this institute, and none will take place so long as we remain true to the spirit of Alexander Lexman."

Alan felt like crying out that Lexman was a bold and daring pioneer, never afraid to take a chance, never worried about expense or public reaction. It was obvious, though, that the people of the Institute had long since fossilized in their patterns. It was a waste of breath to argue with them.
