Dolan went back to work.

He left it to Brown to satisfy the people at the shop, and apparently Brown satisfied them, they sent along the equipment and supplies he requested without comment.

He still had no idea why the time translator worked, but he was beginning to know quite a bit about how it worked, in the sense of functional operation, the input/output relations of the black boxes. A time came when he could have activated the machine by making a few minor connections.

He did not do so.

With the knowledge that he had the technical problem whipped, some of his urgency faded. He could take time to amplify and clarify his knowledge. Quite probably the time translator could never be duplicated by twentieth century technology. At the same time, only a fool would pass up a chance to learn what he could, it was too big a thing, even with the limitations under which it seemed to operate. Also, familiarity with the translator was a weapon, knowledge Brown did not have—a weapon he was grimly intent on using.

He kept testing and checking, varying inputs and measuring outputs.

Remembering what Moirta had said about losing his memory—he did not think he would, if his plans worked out, but there was always the chance of something going wrong—he kept careful notes. Brown watched this activity blandly. Thinking it over, Dolan saw that this was only logical. There were always fires for notes.

So, as an extra precaution, he made copies of the most important data in secrecy and stored them in a glass jar under a rock back of the cottage. Then it occurred to him that he might forget about the jar—or he might not be around to remember it, there was still the gully to keep in mind. Well, what had worked once should work again. He nicked a code message in a piece of wire, showing the location of the notes, and left it in his tool-box.
