There are two classes of the patrons of professional baseball grounds which club Presidents and Directors have their choice in catering to for each season, and these are, first, the reputable class, who prefer to see the game played scientifically and by gentlemanly exemplars of the beauties of the game; and second, the hoodlum element, who revel in noisy coaching, "dirty ball playing," kicking against the umpires, and exciting disputes and rows in every inning. The Chicago, Philadelphia and Boston Clubs in the League have laid out nearly $200,000 within the past two years in constructing their grounds for the express purpose of eliciting the very best patronage of their respective cities. The Brooklyn Club have excelled in this respect in the American Association by constructing their grounds for a similar class of patrons. But all of the clubs have not followed this example, the majority committing the blunder of considering only the tastes and requirements of the hoodlum class apparently in catering for patronage. This is a great financial mistake. Experience has shown conclusively that it pays best to cater solely for the best class of patronage. The work in doing this is so much more satisfactory for one thing, and it is sure to be the most remunerative. If there is any sport which yields a fair equivalent in the special attractions it presents for an admission fee of half a dollar, it is such ball playing as was exhibited during the past season on the grounds of the leading clubs of the National League. A feature of the attendance at the League games of 1888 was the presence of the fair sex in such goodly numbers. Where the ladies congregate as spectators of sports a refining influence is brought to bear which is valuable to the welfare of the game. Besides which, the patronage of ladies improves the character of the assemblages and helps to preserve the order without which first-class patronage cannot be obtained. THE VALUE OF TEAM WORK. Nothing has been more gratifying to the admirers of the game in the practical experience of improved points of play realized during the season of 1888, than the growing appreciation, by the most intelligent patrons of the game, of the value of team work at the bat, and its great superiority as an element of success in winning pennants, to the old school plan of record batting as shown in the efforts to excel solely in home run hitting and the slugging style of batting.
