six-inch (152 mm) bail; the ball must weigh between ; overs last four balls; the no ball is the penalty for overstepping, which means the hind foot going in front of the bowling crease (i.e., in direct line of the wicket); various means of "it is out" are specified – they include hitting the ball twice and obstructing the field; the wicket-keeper is required to be still and quiet until the ball is bowled; umpires must allow two minutes for a new batsman to arrive and ten minutes between innings; the umpire cannot give a batsman out if the fielders do not appeal; the umpire is allowed a certain amount of discretion and it is made clear that the umpire is the "sole judge" and that "his determination shall be absolute". There are four Laws for bowlers but they do not say he must roll the ball and there is no mention of prescribed arm action, only that he must "deliver the ball" with one foot behind the bowling crease. Rowland Bowen, writing in the 1965 edition of Wisden, asserts that the ball was bowled in the true sense (all along the ground) through the first half of the 18th century and that this was the rule prior to the 1750s, though it was largely forsaken by the 1770s after bowlers began pitching the ball. Earliest known scorecards The season is also notable for the two earliest known surviving match scorecards. It is not until the 1772 season that more scorecards of top-class matches have survived, although a handful of cards from minor matches have been found. London v Surrey and Sussex, Artillery Ground, 2 June The first, containing individual scores but no details of dismissals, is from a match between the London Cricket Club and a combined Surrey and Sussex team at the Artillery Ground on 2 June. No titles were given to the teams at the time and various titles, including London v Slindon, have been applied retrospectively by modern authors. London, whose team included given men, was the host club and their opponents were all from the counties of Surrey and Sussex. The scorecard was kept by the 2nd Duke of Richmond at Goodwood House. The card gives the scores by each player and their surnames only, although it does differentiate between the two pairs of brothers (the Harrises and Newlands) who were playing. The Daily Advertiser
