At the moment of Vane's arrival he was discoursing fluently on the problem of education. The point is really immaterial, as Sir John discussed all problems with equal fluency, and the necessity for answering was rare. He had a certain shrewd business-like efficiency, and in most of his harangues there was a good deal of what, for want of a better word, might be termed horse sense. But he was so completely self-opinionated and sure of himself that he generally drove his audience to thoughts of poisons that left no trace or even fire-arms. Especially when he was holding forth on strategy. On that subject he considered himself an expert, and regularly twice a week he emptied the smoking-room at Rumfold by showing--with the aid of small flags--what he would have done had he been in charge of the battle of the Somme in 1916. He was only silenced once, and that was by a pessimistic and saturnine Sapper. "Extraordinary," he murmured. "I congratulate you, Sir John. The plan you have outlined is exactly in every detail the one which the Commander-in-Chief discussed with me when overlooking the charming little village of Gueudecourt. 'Johnson,' he said, 'that is what we will do,' and he turned to the Chief of Staff and ordered him to make a note of it." The Sapper paused for a moment to relight his pipe. Then he turned impressively to Sir John. "There was no Chief of Staff. The Chief of Staff had gone: only a few bubbles welling out of the mud remained to show his fate. And then, before my very eyes, the C.-in-C. himself commenced to sink. To my fevered brain it seemed to be over in a minute. His last words as he went down for the third time were 'Johnson, carry on.' . . . Of course it was kept out of the papers, but if it hadn't been for a Tank going by to get some whisky for the officers' mess, which, owing to its pressure on neighbouring ground squeezed them all out again one by one--you know, just like you squeeze orange pips from your fingers--the affair might have been serious." "I did hear a rumour about it," said the still small voice of a machine-gunner from behind a paper. "Of course," continued the Sapper, "the plan had to be given up. The whole of G.H.Q. sat for days in my dug-out with their feet in hot water and mustard. . . . A most homely spectacle--especially towards the end when, to while away the time, they started sneezing in unison. . . ." A silence settled on the smoking-room, a silence broken at last by the opening and shutting of the door. Sir John had retired for the night. . . . At the moment that Vane paused at the entrance to his bit of fairyland Sir John was in full blast.
