Spalding's Baseball Guide and Official League Book for 1895
“ The most energetic, lively and exciting method of playing a game of ball can mark a professional club contest without its being disgraced by a single act of rowdyism—such as that of spiking or willfully colliding with a base runner; bellowing like a wild bull at the pitcher, as in the so-called coaching of 1893 and 1894; or that of "kicking" against the decisions of the umpire to hide faulty captaincy or blundering fielding. ”
