The bowling crease is limited; because, otherwise, the batsman never could take guard; and umpires should be very careful to call “No Ball,” if the bowler bowls outside the return crease. The return, or crease, is not limited; because it is against a batsman’s interest to run wide of his wicket; and a little latitude is requisite to prevent dangerous collision with the wicket-keeper. VI. The wickets. Secretaries should provide a rule, or frame, consisting of two wooden measures, six feet eight inches long, and four feet apart, and parallel. Then, with a chain of twenty-two yards, the relative positions of the two wickets may be accurately determined. IX. The bowler. “One foot on the ground.” No man can deliver a ball with the foot not touching the ground in the full swing of bowling. So, if the foot is over the crease, there is no doubt of its being on the ground. X. The ball must be bowled: “not thrown or jerked:” here there is not a word about “touching the side with the arm.” It is left to the umpire to decide what is a jerk. We once heard an umpire asked, how could you make that out to be a jerk? “I say it is a jerk because it is a jerk,” was the sensible reply. “I know a jerk when I see one, and I have a right to believe my eyes, though I cannot define wherein a jerk consists.” In a jerk there is a certain mechanical precision and curl of the ball wholly unlike fair bowling. A throw may be made in two ways; one way with an arm nearly straight from first to last: this throw with straight arm requires the hand to be raised as high as the head, and brought down in a whirl or circle, the contrary foot being used as the pivot on which the body moves in the delivery. But the more common throw, under pretence of bowling, results from the hand being first bent on the fore-arm, and then power of delivery being gained by the sudden lash out and straightening of the elbow. It is a mistake to say that the action of the wrist makes a throw. “In delivery” means some action so called: if the mere opening of the hand is delivery of the ball, then the only question is the height of the hand the moment it opens. But if, as we think, “delivery” comprehends the last action of the arm that gives such opening of the hand effect, then in no part of that action may the hand be above the shoulder. Further, in case of doubt as to fair bowling, the umpire is to decide against the bowler; so the hand must be _clearly_ not above the shoulder, and the ball as clearly not thrown, nor jerked.
