Just before the war I came across the ideal game. I forget what it was called, unless it was some such name as "The Prince's Quest." Six princes, suitably coloured, set out to win the hand of the beautiful princess. They started at one end of a long and winding road, and she waited for the first arrival at the other end. The road, which passed through the most enthralling scenery, was numbered by milestones--"1" to "200". Suppose you were the Red Prince, you shook a die (I mean the half of two dice), and if a four turned up, you advanced to the fourth milestone. And so on, in succession. So far it doesn't sound very exciting. But you are forgetting the scenery. Perhaps at the twelfth milestone there awaited you the shoes of swiftness, which carried you in one bound to the twentieth milestone; thus by throwing a three at the ninth, you advanced eleven miles, whereas if you had thrown a four you would only have advanced four miles. On arriving at other lucky milestones you received a cloak of darkness, which took you past various obstacles which were holding the others up, or perhaps were introduced to a potent dwarf, who showed you a short cut forbidden to your rivals. One way and another you pushed ahead of the other princes. And then the inevitable happened. You arrived at the eighty-fourth milestone (or whatever it was) and you found a wicked enchanter waiting for you, who cast upon you a backward spell, as a result of which you had to travel backwards for the next three turns. Undaunted by this reverse, you returned bravely to it, and perhaps came upon the eighty-fourth milestone again. But even so you did not despair, for there was always hope. The Blue Prince, who is now leading, approaches the ninety-sixth milestone. He is, indeed, at the ninety-fifth. A breathless moment as he shakes the die. Will he? He does. He throws a one, reaches the ninety-sixth milestone, topples headlong into the underground river, and is swept back to the starting-point again. A great game. But our edition of it went to some hospital during the war, and I fear now that I shall never play it again. Yet I scan the papers eagerly, hoping for some announcement of it. Not this actual game, of course, but some version of it; some "Christmas novelty," in which, perhaps, the princes are called knights, but the laughter remains the same. The Mathematical Mind My daily paper just now is full of mathematical difficulties, submitted by its readers for the amusement of one of its staff. Every morning he appeals to us for assistance in solving tricky little problems about pints of water and herrings and rectangular fields. The magic number "9" has a great fascination for him. It is terrifying to think that if you multiply any row of figures by 9 the sum of the figures thus obtained is divisible by 9. It is uncanny to hear that if a clock takes six seconds to strike six it takes as much as thirteen seconds and a fifth to strike twelve.
