At the opening of the season in 1891, the members of the Chautauqua Circle counted more than a hundred thousand. Nine classes had been graduated, another large class was to receive its diplomas during that summer, and there were three undergraduate classes each of nearly twenty thousand members, with another class as large in prospect. Only a small section of each class could be present at Chautauqua, the vast majority of its members being far away, some in distant lands. But among those who came to the Assembly, the social spirit was strong. They loved to meet each other, held social reunions and business meetings constantly. Each of the four oldest classes, from '82 to '85, had its own building as headquarters, but all the later classes were homeless and in need of homes. It was a great boon to these classes when at last, in 1891, the C. L. S. C. Alumni Hall was completed and opened. Its eight class-rooms were distributed by lot and furnished by the gifts of the members. As new classes were organized year after year, they were welcomed by the classes already occupying the rooms. It was not many years before each room became the home of two classes, then after eight years more of three classes, meeting on different days, but united in the general reception on the evening before the Recognition Day. Beside the eight class-rooms on the second floor of the Alumni Building there is a large hall which is used before the Recognition Day by the graduating class, and during the rest of the season by the new entering class. In 1916, after the death of Miss Kate F. Kimball, Secretary of the C. L. S. C, this hall was named "The Kimball Room." The Alumni Building with its wide porches became at Chautauqua a social center for the members of the Circle and many have been the friendships formed there. On this season of 1891 the United Presbyterian House was opened.
