AS ADOPTED BY THE NATIONAL LEAGUE AND AMERICAN ASSOCIATION OF PROFESSIONAL BASE BALL CLUBS.

THE BALL GROUND.

The Ground must be an inclosed field, sufficient in size to enable each player to play in his position as required by these Rules.

From a point A, within the grounds project a right line out into the field, and at a point B, 154 feet from point A, lay off lines B C and B D at right angles to the line A B; then with B as centre and 63.63945 feet as radius, describe arcs cutting the lines B A at F and B C at G; B D at H; and B E at I. Draw lines F G, G E, E H and H F, and said lines will be the containing lines of the Diamond or Infield.

THE CATCHER'S LINES.

With F as centre and 90 feet radius, an arc cutting line F A at L, and draw lines L M and L O at right angles to F A; and continue same out from F A not less than 90 feet.

THE FOUL LINE.

From the intersection point F continue the straight lines F G and F H until they intersect with the lines L M and L I, and then from the points G and H in the opposite direction until they reach the boundary lines of the grounds.

THE PLAYER'S LINES.

With F as centre and 50 feet radius, describe arcs cutting lines F O and E M at P and Q, then with F as centre again and 75 feet radius describe arcs cutting F G and F H at R and S; then from the points P Q R and S draw lines at right angles to the lines F O, F M, F G, and
