“Sentenced to be shot at sunrise!” the president of the court announced. The world spun around with me. But only for a second. My self-control came to my aid. With the curious detachment that comes to us in such emergencies, I noted that the court-martial was being held in Professor Vibens’ office; that dingy little Victorian room, where I had first told my story of traveling by relativity and had first realized that I had come to the _t_-dimensional world. Apparently it was also to be the last room I was to see in this same world. I had no false hopes that the execution would help me back to my own world, as such things sometimes do in stories. When life is gone, it is gone, whether in one dimension or another. I would be just as dead in the _z_ dimension as in the _t_ dimension. “Now, Einstein, or never!” I thought. “Come to my aid, O Riemaun! O Lobatchewsky! If anything will save me it will have to be a tensor or a geodesic.” I said it to myself rather ironically. Relativity had brought me here. Could it get me out of this? Well! Why not? If the form of a natural law, yea, if a natural object varies with the observer who expresses it, might not the truth and the meaning of the gostak slogan also be matter of relativity? It was like making the moon ride the tree tops again. If I could be a better relativist, and put myself in these people’s place, perhaps I could understand the gostak. Perhaps I would even be willing to fight for him or it. The idea struck me suddenly. I must have straightened up and some bright change must have passed over my features, for the guards who led me looked at me curiously and took a firmer grip on me. We had just descended the steps of the building and had started down the walk. Making the moon ride the tree tops! That was what I needed now. And that sounded as silly to me as the gostak. And the gostak did not seem so silly. I drew a deep breath and felt very much encouraged. The viewpoint of _relativity_ was somehow coming back to me. Necessity manages much. I could understand how one might fight for the idea of a gostak distimming the doshes. I felt almost like telling these men. Relativity is a wonderful thing. They led me up the slope, between the rows of poplars. Then it all suddenly popped into my head; how I had gotten here by changing my coordinates, insisting to myself that I was going upwards. Just like making the moon stop and making the trees ride, when you are out riding at night. Now I was going _upwards_. In my own world, in the _z_ dimension, this same poplar was _down_ the slope. “It’s downwards!” I insisted to myself. I shut my eyes, and imagined the building behind and _above_ me. With my eyes shut, it did seem downwards. I walked for a long time before opening them. Then I opened them and looked around.
