The Relations of Geodesy to Geology1

THE study of the earth is the aim of both geologists and geodesists, but their methods of investigation differ so widely that their cooperation is sometimes difficult to bring about. While the geologist utilises descriptions and measurements which he has collected at many places widely distributed over the earth's surface, the geodesist deals with a comparatively limited number of observations carried out with the aid of instruments of high precision, and carefully corrected for all ascertainable errors; his material for discussion is provided from data the magnitudes of which are very small, and the weight and relevance of which are not readily appreciated by workers whose advance is along other lines. Still, the co-operation of geology and geodesy is very desirable, and the work that has been done during the past ten or fifteen years in India where the most extensive collection of high-grade geodetic, material in the Empire is available, in bringing together these two lines of investigation may lead, we hope, to further work both there and elsewhere. The reports of the Geodetic Survey of South Africa furnished some similar material, and Dr. W. Bahn in an article which appeared in the Beiträge f¨r Geophysik of 1910, discussed the geodetic results and indicated their bearing on the tectonic geology of the area; but such discussions have been few.
