operations: (a) Where practical, existing station monuments of the two previous surveys will be recovered and incorvorated into the proposed scheme. A minimum number of stations will be tied in to allow a check to be made between the results of this survey and that of the Joint Task Force Seven Survey. (>) Existing towers can be adapted to the requirements of the survey and new towers erected at remaining locations as shown on following list: TOWER ERECTION Station Name Location Aniyaanii Parry Kodak Steel Use existing steel tower " " " n Photo N.

These heights may be modified after ob- taining the heights of the tower bases above the level of the lagoon. Allow- ance is made for curavture of the earth and a ten-foot minimum clearance above v-5
