He was safe, he was restored to his privacy. He stopped to light his pipe, looked once at his wife and son in the window, and as one raises one’s eyes from a page in an express train and sees a farm, a tree, a cluster of cottages as an illustration, a confirmation of something on the printed page to which one returns, fortified, and satisfied, so without his distinguishing either his son or his wife, the sight of them fortified him and satisfied him and consecrated his effort to arrive at a perfectly clear understanding of the problem which now engaged the energies of his splendid mind.
It was a splendid mind. For if thought is like the keyboard of a piano, divided into so many notes, or like the alphabet is ranged in twenty-six letters all in order, then his splendid mind had no sort of difficulty in running over those letters one by one, firmly and accurately, until it had reached, say, the letter Q. He reached Q. Very few people in the whole of England ever reach Q. Here, stopping for one moment by the stone urn which held the geraniums, he saw, but now far far away, like children picking up shells, divinely innocent and occupied with little trifles at their feet and somehow entirely defenceless against a doom which he perceived, his wife and son, together, in the window. They needed his protection; he gave it them. But after Q? What comes next? After Q there are a number of letters the last of which is scarcely visible to mortal eyes, but glimmers red in the distance. Z is only reached once by one man in a generation. Still, if he could reach R it would be something. Here at least was Q. He dug his heels in at Q. Q he was sure of. Q he could demonstrate. If Q then is Q—R—Here he knocked his pipe out, with two or three resonant taps on the ram’s horn which made the handle of the urn, and proceeded. “Then R …” He braced himself. He clenched himself.
Qualities that would have saved a ship’s company exposed on a broiling sea with six biscuits and a flask of water—endurance and justice, foresight, devotion, skill, came to his help. R is then—what is R?
