In the gallery are collections of minerals and an extensive series of stone-age tools and weapons. In front of this gallery and over the hallway and two front rooms of the lower story is the library, which can be used as a hall for a reasonably large audience.

Nominally it contains more than forty thousand volumes; but this number must be considerably reduced, as latterly single issues of periodicals have been catalogued under distinct numbers. With all reductions made, however, the library is important. Publications in twenty-two different tongues are on its exchange list.

Publication of a final report and an archaeological map. 5. Preparation of a series of diagrams and casts of an educational character for distribution to the higher institutions of learning in the State.

The first two parts of the plan have been accomplished, and the academy is now endeavoring to carry out the third. While the academy has given and is giving considerable attention to archaeology, it is not neglecting other lines of science, and papers of importance in geology, botany, and entomology are in its hands for publication in the near future.

Thirty years is not a long time, even in America. In December, 18!7, the academy will celebrate its thirtieth anniversary by a special meeting. It may then look back with pride over its record. From a membership of four meeting in an office, it has grown
