NEW ENGLAND WATERWORKS ASSOCIATION. The June Field Day of the New England Waterworks association was held on Wednesday, June 13. The members, with guests, assembled in the United States Navy yard at Charlestown, and visited the new dry dock, battleships and other points of importance. After visiting the Navy yard, the members sailed down the harbor, stopping for luncheon on the way and afterwards visiting by the steamer some of the points in the harbor of scientific and military interest, returning to Boston about five p. m. Several ladies joined in the excursion, which was unusually interesting and agreeable. The annual September convention will be held in the White mountains; details will be announced at an early date.
