Pitcher Chamberlain says: "I don't see why anybody can't make a good umpire. The way I figure it out there are only two requisites. One is to keep your eye on the ball at all times. Then there is no chance of missing the play, for no play can be made without the ball. Another thing is to keep the players from talking back. Don't let them argue with you under any circumstances. That is how Lynch and Gaffney succeeded. They make mistakes just as other umpires do; but they won't allow any back talk and the consequences is their decisions are now roasted from the stands."-The New York Times, September 6, 1892
Keep your eye on the ball and don't take any guff-that's good advice for anybody.
