"Well, I'm not majoring in History, myself, but I think it's an outrage that some people's diplomas are going to depend on grades given by a lunatic!" "Mine will, and I'm not going to stand for it. My old man's president of the Alumni Association, and...." That was something he had not thought of, before. It gave him an ugly start. He was still thinking about it as he turned into the side hall to the History Department offices and entered the cubicle he shared with a colleague. The colleague, old Pottgeiter, Medieval History, was emerging in a rush; short, rotund, gray-bearded, his arms full of books and papers, oblivious, as usual, to anything that had happened since the Battle of Bosworth or the Fall of Constantinople.

And the time he'd tried to get a copy of Franchard's Rise and Decline of the System States, which wouldn't be published until the Twenty-eighth Century, out of the college library. None of those had drawn much comment, beyond a few student jokes about the history professor who lived in the future instead of the past. Now, however, they'd all be remembered, raked up, exaggerated, and added to what had happened this morning. He sighed and sat down at Marjorie's
