Early in 1924 it was realized by the Executive Committee of the Section that the agenda for the Madrid meeting would be a very heavy one. As is well known, the geodetic work that is considered by the Section consists of a number of branches; among them may be enumerated—astronomic longitudes, latitudes and azimuths; measurement of base lines; triangulation of various degrees of precision; traverse, precise leveling, gravimetric surveys, mean sea level, which furnishes starting points for leveling; variation of latitude; projections; figure of the earth; the theory of isostasy; and trigonometric leveling. Each of the foregoing subjects should be considered at an international conference, for it is only by securing the active co‐operation of geodesists in the various countries that the best results can be obtai
