"MY DEAR BILL,--Many thanks for your jolly letter. I write at once to tell you how awfully interested I am in what you tell me. It really is a most extraordinary thing, though, as you know, it often happens. On the very day your letter arrived I met Carville again! Without any warning I heard the chuff-chuff of a motor in the lane, and saw him walking up to the door. I asked him in, of course. He sniffed and coughed a good bit, because I was biting a big plate, and the fumes are pretty thick even with nitric acid. He wanted to know all about what I was doing. Of course I explained, asked him to sit down and have a drink, and for a time we got on very well. I said I supposed he was touring, and he remarked: "'Oh, no. I'm living down here just at present,' "'What, broke again?' I asked laughing. He looked at me in that fiery damn-your-eyes way of his and then joined in the laugh. 'No,' he said, 'experimenting. I've taken up flying.' "He said it just as you might say, 'I've taken up tennis.' He gives you the impression that if he remarked that he had taken up cathedral-building or unicorn-breeding, you would believe him. A most remarkable man! "I said, 'Oh, I've heard something about your people, I believe, Carville,' and took up your letter. He put his whisky down on the floor (he was sitting in my low window seat) and glared at me. 'At least,' I said, funking, you know, 'I see it's the same name.' And I went on to tell him how I'd been so impressed with my first adventure with him that I'd written to you about it. He held out his hand for the letter. I just sat and watched him. He read the whole thing rapidly, his eyes going back again and again to some parts of it; and then he gave it back to me. "'So that's where he is, eh?' he said, and smiled. He took out a pocket-book and made a note of the address. "'Who,' I said. "'Charley, dear old Charley,' he said, 'I haven't seen him or heard from him for years.' "'Then it is your brother?' I asked. He nodded. "'He always was a bit of a duffer,' he said. 'What's N. J.?' he asked suddenly. "'New Jersey,' I replied, 'in the United States.' "'Oh,' said he, 'I thought it meant New Jerusalem. It would be like Charley.'
