"Sheep are especially sensitive to the exact moment of the turn of the tide. In this game, nine tethered sheep react, pull on the stakes, jolt the chairs and rattle the tea-cups. Bets are taken on the combined sensitivity of any three line of sheep - read vertically, horizontally or diagonally. Since there are normally three tide-turns every twenty-four hours, it is normal practice to take the best of three results. Reliable clocks, calendars and time-tables are used to determine accuracy of the sheep's forecast. A referee should be appointed to determine fair play, distinguishing correct reactions from other interferences. On the account of their special relationship with sheep, shepherds are disqualified."
