JUAN -has been moat helpful and has sb,own keenness and ability in, developing the various epplioaticus of yaw methods which have evolved during his stay. 3. The original demonstration oonsisting of the produotion of a relief model from two oblique photograpns, while in%resting had little practical application in this theatre awing to the availability of vertical air photos-aphs of all areas. It was seen at ammo, however, that the basic method oould be used to solve a number of problem IwaviousIsy insoluble here. 4. Lt.
