The second general assembly of the Union took place in Madrid, beginning October 1, 1924, in the building of the National Parliament. The king of Spain presided at the first meeting and the proceedings consisted of addresses of welcome. Then for a week the several sections met in different rooms and discussed matters of special interest to themselves. There are now thirty nations adhering to the Union, and nearly all were represented by delegates or by proxy. The United States had but four delegates, which made it impossible to keep in close touch with the discussions of the seven sections. At the final meeting on October 8 the several sections reported the results of their conferences to the general assembly.
