We had neared the châlet again. I saw the peat smoke rising against the background of the ridges. The “man” was whistling at his work in the yard behind the building. The column of smoke, I remember, was agitated by the wind towards the top; it turned, blew downwards. No other sign of movement was anywhere visible, for in the bottom of the hollow where we now stood, the wind did not even stir the isolated larches or tall yellow gentians. Sunshine flooded everything. Out of this peace and stillness then came a sudden cry and the sight of something moving rapidly--both from the châlet. “Julius!” called a shrill voice, as the figure of Mrs. LeVallon, with flying hair and skirts, came running over the meadow towards us. “Julius!--Professor! Quick!” The voice and figure startled me; both came, it seemed, out of some other place; a picture from my youth rose up--a larch grove in October upon the Pentland Hills. I experienced a sense of deep and thrilling beauty similar to what I had felt then. But as I watched the slim, hurrying figure I was aware of another thing that left me breathless: For with her, as she passed through chequered sun and shadow along the fringe of forest, there moved something else enormously larger than herself. It was in the air about her. Like that strange Pentland memory, it whirled. It was formless, and owing to its huge proportions gave the impression of moving slowly, yet its very formlessness was singularly impressive and alive, so that the word “body” sprang instantly into my mind. Actually it moved at a tremendous speed. In my first confusion and bewilderment I remember saying aloud in sheer amazement: “a fragment of the day has broken off; it’s clothed in wind and sunlight!” A phrase quite meaningless, of course, yet somehow accurately descriptive, for it appealed to me as a fragment of conditionless, universal activity that had seized upon available common elements to furnish itself a visible appearance. I got the astounding suggestion that it was heat and air moving under intelligent and conscious direction. Combined with its airy lightness there was power, for in its brief, indeed its instantaneous, appearance I felt persuaded of an irresistible strength that no barrier of solid matter could possibly withstand. At the same time it was transparent, for I saw the trees upon its further side. It passed ahead of the human figure, so close it seemed to touch her dress, rose with a kind of swift, driving plunge into the air, slipped meltingly into the clean blue colour of the atmosphere--and disappeared. And so swift was the entire presentment of the thing, that even while I tried to focus my sight upon it to make sure I was not deceived, it had both come and gone. The same second Julius caught my arm. I heard him utter a quick, low cry, stifled instantly. He gasped. He quivered. I heard him whispering:
