A thing can sometimes be too extraordinary to be remembered. If it is clean out of the course of things, and has apparently no causes and no consequences, subsequent events do not recall it, and it remains only a subconscious thing, to be stirred by some accident long after. It drifts apart like a forgotten dream; and it was in the hour of many dreams, at daybreak and very soon after the end of dark, that such a strange sight was given to a man sculling a boat down a river in the West country. The man was awake; indeed, he considered himself rather wide awake, being the political journalist, Harold March, on his way to interview various political celebrities in their country seats. But the thing he saw was so inconsequent that it might have been imaginary. It simply slipped past his mind and was lost in later and utterly different events; nor did he even recover the memory till he had long afterward discovered the meaning. Pale mists of morning lay on the fields and the rushes along one margin of the river; along the other side ran a wall of tawny brick almost overhanging the water. He had shipped his oars and was drifting for a moment with the stream, when he turned his head and saw that the monotony of the long brick wall was broken by a bridge; rather an elegant eighteenth-century sort of bridge with little columns of white stone turning gray. There had been floods and the river still stood very high, with dwarfish trees waist deep in it, and rather a narrow arc of white dawn gleamed under the curve of the bridge.
