NOUGHTS AND CROSSES

Answers to Correspondents N fact, answers to hundreds of i correspondents about our own little problem of the noughts and crosses on the foreheads of the three job-seekers in our last issue. They were big correspondents and little correspondents, thin and fat correspondents, mostly sad correspondents, including Mother of Ten, Christchurch; Winnie the Poo, Dunedin; Nerts, Auckland; Disillusioned M.P., Wellington; and last but not least, Bewildered. We should have mentioned that one man did bring his hand down and did get the job and, in case you still have not worked out what you have to do, try and decide how this man decided he was justified in saying he knew what was on his forehead. And to all those worried by the water lily: Yes, it certainly was a large lake. We hope you enjoyed working out its area. But really, you know, that was not quite the point. About Smith: The Police Force has brought up all back numbers and the edition is out of print. Try the library. And to all those who did not read Puzzle Page in The Listener of October 27:-Don’t. But try this one: A ship lies in port. Over her side hangs a ladder. The rungs are eighteen inches apart. As the tide rises the rope of which the ladder is made shrinks at the rate of 1 inch to every foot covered. The tide rises at the rate of one foot every hour. In how many hours on a rising tide would four rungs of the ladder be completely covered?
