4th The New York Sunday Mercuryreports that “Rule 6 was amended by adding a clause to section 6 that prohibits any fence from being erected within 90 feet of home base, unless it be to mark the boundary of the grounds, in which case, if it be less than 90 feet, all passed balls touching such fence are to give one base.” (as noted by Richard Harshberger).
