"These men are very much interested in your case," the doctor tells me. "I have been telling them about your statement and the strange circumstances attending your appearance on Fifty-Second Street today. Now I feel that you have had enough rest and I want you to tell them the entire story." Well, I know they will figure I am off the beat, but I start at the beginning and relate the whole story anyway. They do not say a word until I have finished. Then they look at each other and have a whispered session on the other side of the room. Finally one of them speaks up. "Mr. McRae," he says, "we want to question you a little further if you don't mind. Will you please put on your clothes and come with us?" I do like they say since there is nothing else for me to do, and when I am dressed they take me down the hall to a big light room which is practically all glass, and they ask me to sit down at a large table. "Now, Mr. McRae," the first doc says, "I want you to do something for me." He hands me ten little blocks of different sizes and informs me that I am to place them in the proper holes in a board which he has ready for just that purpose. I do as he asks. These seems to surprise him, but he is all set with another test, and I spend the rest of the afternoon playing these little games, until I am plenty weary of it and I say so to him. "Well," he says, "as you likely know, we have been trying to determine your sanity. I will say that you have demonstrated yourself to be entirely normal." "That is fine," I say, "but now that we have decided that will someone kindly tell me what is this business about Twenty-Five O Seven--and what has been happening to me anyhow." Another of the doctors answers me. "There seems to be only one other explanation," he says, "one which we are reluctant to accept but which we must consider if your story is true. You have been in a fourth dimension. The passage of time there is something that we know nothing of, and it is possible that the few months you spent in it were equivalent to the centuries which have passed in this dimension. You have apparently evolved a unique and purely personal method for entering and leaving the fourth dimension, and since it seems entirely dependent on your own physical skill together with a large element of chance, it is of little value for scientific exploitation. That is the pity." While he is giving out this statement, the rest of the doctors grow very excited, and soon as he has finished they begin throwing questions at him about curvature of space and Neilson's theory and a lot of other stuff which is very confusing to me indeed. Finally I stop them. "If you will kindly return my trombone," I tell them, "I will be on my way, as I do not know anything of all this and I would like to get out and see what it is like in Twenty-Five O Seven A.D."
