After about an hour of this and a couple of pipes, Smith confesses that he began to feel extremely drowsy. He was just wondering whether it would be pleasant to stretch himself out on the wild thyme that scented the high place and go to sleep till breakfast, when the mounting sun caught one of the monastery windows, and Smith stared sleepily at the darting flashing light till it dazzled him. Then he felt "queer." There was an odd sensation as if the top of his head were dilating and contracting, and then he says he had a sort of shock, something between a mild current of electricity and the sensation of putting one's hand into the ripple of a swift brook. Now, what happened next Smith cannot describe at all clearly. He knew he was on Giltar, looking across the waves to Caldy; he heard all the while the hollow, booming tide in the caverns of the rocks far below him, And yet he saw, as if in a glass, a very different country--a level fenland cut by slow streams, by long avenues of trimmed trees. "It looked," he says, "as if it ought to have been a lonely country, but it was swarming with men; they were thick as ants in an anthill. And they were all dressed in armour; that was the strange thing about it. "I thought I was standing by what looked as if it had been a farmhouse; but it was all battered to bits, just a heap of ruins and rubbish. All that was left was one tall round chimney, shaped very much like the fifteenth-century chimneys in Pembrokeshire. And thousands and tens of thousands went marching by. "They were all in armour, and in all sorts of armour. Some of them had overlapping tongues of bright metal fastened on their clothes, others were in chain mail from head to foot, others were in heavy plate armour. "They wore helmets of all shapes and sorts and sizes. One regiment had steel caps with wide trims, something like the old barbers' basins. Another lot had knights' tilting helmets on, closed up so that you couldn't see their faces. Most of them wore metal gauntlets, either of steel rings or plates, and they had steel over their boots. A great many had things like battle-maces swinging by their sides, and all these fellows carried a sort of string of big metal balls round their waist. Then a dozen regiments went by, every man with a steel shield slung over his shoulder. The last to go by were cross-bowmen." In fact, it appeared to Delamere Smith that he watched the passing of a host of men in mediæval armour before him, and yet he knew--by the position of the sun and of a rosy cloud that was passing over the Worm's Head--that this vision, or whatever it was, only lasted a second or two. Then that slight sense of shock returned, and Smith returned to the contemplation of the physical phenomena of the Pembrokeshire coast--blue waves, grey St. Margaret's, and Caldy Abbey white in the sunlight.
