Interscholastic Base-Ball.

It is announced that the Harvard Base-Ball Association has offered a cup for which the principal preparatory schools in New England will have a chance to compete. The present plan is to arrange a series of games between the nines of the preparatory schools which are situated in or very near Boston. Then a team picked from the best players of these nines is to play a game on Jarvis Field with the winning nine of the annual Andover-Exeter game. It is not yet surely known whether or not Andover and Exeter will enter into the scheme, but there is every reason to suppose that they will readily consent to form a part of the association. The Andover and Exeter men in college are enthusiastic over the plan, for it cannot but prove of great benefit both to Andover and to Exeter. The incentive given to both schools to put forth every effort in order to win the annual game, and thus be one of the contestants in the final struggle for the cup, will be great. The Boston schools will also have much to gain from a membership in the association. It is probable that either Exeter or Andover will generally be the winner of the cup, but that result is by no means certain, and the Boston schools will have the advantage of being able to choose the best men from several nines. At present the plan is to play the final game between the picked nine and Exeter or Andover in Cambridge. A large number of graduates of all the schools are at Harvard, and here will probably be centered the greater part of all the interest taken in the welfare of the association.
