He had put two chairs together, front to front, and was standing over them, if that conveys it to you. Then he jumped up, turned round in the air, and came down facing the other way. "Can _you_ do it?" I said to Miss Power. "Come and try," said Bob to me. "It's not really difficult." I went and stood over the chairs. Then I moved them apart and walked over to my hostess. "Good-bye," I said; "I'm afraid I must go now." "Coward!" said somebody, who knew me rather better than the others. "It's much easier than you think," said Bob. "I don't think it's easy at all," I protested. "I think it's impossible." I went back and stood over the chairs again. For some time I waited there in deep thought. Then I bent my knees preparatory to the spring, straightened them up, and said.$1hat happens if you just miss it?" "I suppose you bark your shins a bit." "Yes, that's what I thought." I bent my knees again, worked my arms up and down, and then stopped suddenly and said: "What happens if you miss it pretty easily?" "Oh, _you_ can do it, if Bob can," said Miss Power kindly. "He's practised. I expect he started with two hassocks and worked up to this. I'm not afraid, but I want to know the possibilities. If it's only a broken leg or two, I don't mind. If it's permanent disfigurement I think I ought to consult my family first." I jumped up and came down again the same way for practice. "Very well," I said. "Now I'm going to try. I haven't the faintest hope of doing it, but you all seem to want to see an accident, and anyhow, I'm not going to be called a coward. One, two, three...." "Well done," cried everybody. "Did I do it?" I whispered, as I sat on the floor and pressed a cushion against my shins. "Rather!" "Then," I said, massaging my ankles, "next time I shall try to miss." XXXVIII. A BILLIARD LESSON I was showing Celia a few fancy strokes on the billiard table. The other members of the house-party were in the library, learning their parts for some approaching theatricals--that is to say, they were sitting round the fire and saying to each other, "This _is_ a rotten play." We had been offered the position of auditors to several of the company, but we were going to see _Parsifal_ on the next day, and I was afraid that the constant excitement would be bad for Celia. "Why don't you ask me to play with you?" she asked. "You never teach me anything." "There's ingratitude. Why, I gave you your first lesson at golf only last Thursday." "So you did. I know golf. Now show me billiards." I looked at my watch. "We've only twenty minutes. I'll play you thirty up." "Right-o. What do you give me--a ball or a bisque or what?" "I can't spare you a ball, I'm afraid. I shall want all three when I get going. You may have fifteen start, and I'll tell you what to do." "Well, what do I do first?" "Select a cue." She went over to the rack and inspected them. "This seems a nice brown one. Now then, you begin."
