"Well, offhand—" Jesperson thought for a moment. "Say, a million three hundred. I've made some good investments this past year."

Alan nodded. "Good. Keep the money piling up. I may decide to open a research lab of my own, and we'll need every credit we've got."

But the next day an item arrived in the morning mail which very much altered the character of Alan's plans for the future. It was a small but thick package, neatly wrapped, which bore as return address the name Dwight Bentley, with a London number.

Alan frowned for a moment, trying to place the name. Then it came back to him—Bentley was the vice-provost of the London Institute of Technology, Cavour's old school. Alan had had a long talk with Bentley one afternoon in January, about Cavour, about space travel, and about Alan's hopes for developing a hyperspace drive.

The parcel was the right size and thickness to contain a book. Alan slit the fastenings, and folded back the outer wrapper. A note from Bentley lay on top.

London
3rd November 3877

My dear Mr. Donnell:

Perhaps you may remember the very enjoyable chat you and I had one day at this Institute last winter, on the occasion of your visit to London. You were, I recall, deeply interested in the life and work of James H. Cavour, and anxious to carry on the developments he had achieved in the field of space travel.

Several days ago, in the course of an extensive resurveying of the Institute's archives, the enclosed volume was discovered very thoroughly hidden in the dusty recesses of our library. Evidently Mr. Cavour had forwarded the book to us from his laboratory in Asia, and it had somehow become misfiled.

I am taking the liberty of forwarding the book on to you, in the hopes that it will aid you in your work and perhaps ultimately bring you success. Would you be kind enough to return the book to me c/o this Institute when you are finished with it?
