Abstract
The problem of deflection of the vertical is presented and ways it is often solved are summarized. The gravimetric method is outlined and the details of its actual use are listed. The results of the preliminary gravimetric calculations made for 1 Midas location and 8 FLR stations are given. The proposed project to complete the deflection calculations gravimetrically and to determine the deflection at any other station in the Indian Wells Valley is outlined. Proposals for future extension and sophistication of the gravity project are included. A comparison is made between the gravimetric and astronomic-geodetic methods. (Author)
