original stations of the U. S. S, BOWDITCH Survey of 1944, and one sta~ tion taken directly fram the U. S. S, BOWDITCH Survey of Eniwetok. Stations were located so that all Project islands were tied in directly to the scheme or could be tied in by local triangulation, A new station in the lagoon off the south end of Runit Island was established to strengthen the base expansion quadrangle. Japtan was not included in the control requirements, but could be tied in by local triangulation, To simplify reference to stations, where practical they have been given the name of the island on which they are located. Some of the U. S. S,. BOWDITCH and Joint Task Force Seven stations have been renamed and reference to the renaming is made in the station recovery notes.

GEOGRAPHIC POSITION AND AZIMUTH In the interests of economy and because little accuracy would be lost thereby, it was originally planned to accept the geographic position of station North Base and the azimuth of the new base line as the origin of position and azimuth, as well as the length of the base line. But, after the new station Pinnacle had been built in the lagoon and the base expansion quadrangle could be observed, results indicated that the loc- ation of the North Base marker was eccentric to the position established by the Task Force Seven Survey and could not be accepted as the point of orgin of the H&N survey.
