The convention of the National Lawn Tennis Association, held in New York on March 3d, was attended by representatives of only sixteen out of the forty clubs belonging to the association. Harvard was represented by proxy. It is with surprise that we learn that a motion prohibiting proxy voting was lost. With any amount of proxy voting allowed the meetings cannot attend properly to the discussion of important points, such as the rules of the game. We presume, however, that this means that the executive committee decides on the measures to be adopted, and the meeting merely endorses their decision. Among the amendments made in the rules was the change in the height of the net at the poles from 4 feet to 3 feet 6 inches. This will favor placing along the side lines. Another change is that the server is required to have one foot inside or on the base line and the other foot outside the base line and on the ground. This will prevent the possibility of standing entirely outside of the court when serving. A further amendment requires the umpire to transfer players from one end of the courts to the other at the end of every game in case one court for any reason is preferable. Formerly players were so changed after each odd game - first, third, fifth, etc. This rule can, we think, apply only to deuce sets, as otherwise there might be a manifest disadvantage to one of the players. A motion to do away with two services was lost. The Ayers balls, imported into this country, were declared to be only "the refuse balls of the English market." As Peck & Snyder and Wright & Ditson have joined in making a combination ball, which the executive committee believe will be better than any balls yet used in this country, this ball was adopted by the association as the regulation ball for the ensuing year. These balls will be furnished to association clubs for $5 a dozen. Our Tennis Association should take means to supply these balls to members.
