We grovelled round for half an hour, and found sixteen. He said he hoped we had got them all, because, if not, it would make a serious difference to the machine. He said there was nothing you should be more careful about in taking a bicycle to pieces than seeing you did not lose any of the balls. He explained that you ought to count them as you took them out, and see that exactly the same number went back in each place. I promised, if ever I took a bicycle to pieces I would remember his advice. I put the balls for safety in my hat, and I put my hat upon the doorstep. It was not a sensible thing to do, I admit. As a matter of fact, it was a silly thing to do. I am not as a rule addle-headed; his influence must have affected me. He then said that while he was about it he would see to the chain for me, and at once began taking off the gear-case. I did try to persuade him from that. I told him what an experienced friend of mine once said to me solemnly:-- "If anything goes wrong with your gear-case, sell the machine and buy a new one; it comes cheaper." He said: "People talk like that who understand nothing about machines. Nothing is easier than taking off a gear-case." I had to confess he was right. In less than five minutes he had the gear- case in two pieces, lying on the path, and was grovelling for screws. He said it was always a mystery to him the way screws disappeared. We were still looking for the screws when Ethelbertha came out. She seemed surprised to find us there; she said she thought we had started hours ago. He said: "We shan't be long now. I'm just helping your husband to overhaul this machine of his. It's a good machine; but they all want going over occasionally." Ethelbertha said: "If you want to wash yourselves when you have done you might go into the back kitchen, if you don't mind; the girls have just finished the bedrooms." She told me that if she met Kate they would probably go for a sail; but that in any case she would be back to lunch. I would have given a sovereign to be going with her. I was getting heartily sick of standing about watching this fool breaking up my bicycle. Common sense continued to whisper to me: "Stop him, before he does any more mischief. You have a right to protect your own property from the ravages of a lunatic. Take him by the scruff of the neck, and kick him out of the gate!" But I am weak when it comes to hurting other people's feelings, and I let him muddle on. He gave up looking for the rest of the screws. He said screws had a knack of turning up when you least expected them; and that now he would see to the chain. He tightened it till it would not move; next he loosened it until it was twice as loose as it was before. Then he said we had better think about getting the front wheel back into its place again.
