tained on the reconnaissance trip of October 19,8 by members of this organiza= tion reveal the following facts: (a) Observations were made at night and apparently followed first order procedure. The base line was measured with Invar tapes and Standard procedure followed. Triangle closure is within the allowable maximums. (b) The geometry of the scheme does not conform to first or sec= ond order specifications of the U.S. Coast and Geodetic Survey, and can be considered no better than third order. (c) The initial triangle in the base expansion figure has an R, of 52 which considerably exceeds the allowable maximums of 25 for first order and 40 for second order procedure. This weakens the whole scheme. (d) The area covered by the survey is smaller than that required for this project. Proposed requirements would expand the net to double its present area with considerable magnification of the possible errors in the original net. (e) The base line of the Joint Task Force Seven Survey can be used in a satisfactory scheme and can be assumed, based on available information, to have sufficient accuracy for the proposed second order scheme. (f) The geographical position and azimuth are based on a wartime survey of doubtful precision. As the records of the Naval survey are not available, the method used in establishing position and azimuth are unknown, and it can be assumed speed may have been of more importance than extreme accuracy. However, this does not effect relative positions within the limits of the Atoll. II = 13
