But topics exhaust themselves and, at the last, I myself brought the talk round to the Fourth Dimension. We were sauntering along the forgotten valley that lies between Hardves and Stelling Minnis; we had been silent for several minutes. For me, at least, the silence was pregnant with the undefinable emotions that, at times, run in currents between man and woman. The sun was getting low and it was shadowy in those shrouded hollows. I laughed at some thought, I forget what, and then began to badger her with questions. I tried to exhaust the possibilities of the Dimensionist idea, made grotesque suggestions. I said: And when a great many of you have been crowded out of the Dimension and invaded the earth you will do so and so? something preposterous and ironical. She coldly dissented, and at once the irony appeared as gross as the jocularity of a commercial traveller. Sometimes she signified: Yes, that is what we shall do; signified it without speaking?by some gesture perhaps, I hardly know what. There was something impressive?something almost regal?in this manner of hers; it was rather frightening in those lonely places, which were so forgotten, so gray, so closed in. There was something of the past world about the hanging woods, the little veils of unmoving mist?as if time did not exist in those furrows of the great world; and one was so absolutely alone; anything might have happened. I grew weary of the sound of my tongue. But when I wanted to cease, I found she had on me the effect of some incredible stimulant.
