RULE 9. The Batsman's Lines must be straight lines forming the boundaries of a space on the right, and of a similar space on the left of the Home Base, six feet long by four feet wide, extending three feet in front of and three feet behind the center of the Home Base, and with its nearest line distant six inches from the Home Base.
RULE 10. The Three Feet Lines must be drawn as follows: From a point on the Foul Line from Home Base to First Base, and equally distant from such bases, shall be drawn a line on Foul Ground, at a right angle to said Foul Line, and to a point three feet distant from it; thence running parallel with said Foul Line, to a point three feet distant from the First Base; thence in a straight line to the Foul Line, and thence upon the Foul Line to point of beginning.
RULE 11. The lines designated in Rules 4, 5, 6, 7, 8, 9, and 10 must be marked with chalk or other suitable material, so as to be distinctly seen by the Umpire. They must all be so marked their entire length, except the Captain's and Player's Lines, which must be so marked for a distance of at least thirty-five yards from the Catcher's Lines.
THE BALL.
RULE 12. The Ball.
SEC. 1. Must not weigh less than five or more than five and one-quarter ounces avoirdupois, and measure not less than nine nor more than nine and one-quarter inches in circumference. The Spalding League Ball, or the Reach American Association Ball must be used in all games played under these rules.
SEC. 2. For each championship game two balls shall be furnished by the Home Club to the Umpire for use. When the ball in play is batted over the fence or stands, on to foul ground out of sight of the players, the other ball shall be immediately put into play by the Umpire. As often as one of the two in use shall be lost, a new one must be substituted, so that the Umpire may at all times, after the game begins, have two for use. The moment the Umpire delivers the alternate ball to the catcher or pitcher it comes into play, and shall not be exchanged until it, in turn, passes out of sight on to foul ground.
SEC. 3. In all games the ball or balls played with shall be furnished by the Home Club, and the last ball in play becomes the property of the winning club. Each ball to be used in championship games shall be examined, measured and weighed by the Secretary of the Association, inclosed in a paper box and sealed with the seal of the Secretary, which seal shall not be broken except by the Umpire in the presence of the captains of the two contesting nines after play has been called.
SEC. 4. Should the ball become out of shape, or cut or ripped so as to expose the yarn, or in any way so injured as to be—in the opinion of the Umpire—unfit for fair use, the Umpire, on being appealed to by either captain, shall at once put the alternate ball into play and call for a new one.
