Though this series of correspondence was bound into volumes bearing numbers from the same series as CSO 8, it was controlled by a new series of registration numbers (1-990) and a new index was compiled for it (CSO 13). The period covered runs from the latter part of Eardley-Wilmot's administration to approximately the end of that of C.J. La Trobe (Administrator).

An analysis of subject matter reveals that much the same kind of functions were dealt with by the office having control of this series as was the case with CSO 8; but once again the distinction between this and the companion series (CSO 20) is not clearly defined, and it can be said only that there is a tendency for certain subjects to be dealt with in this correspondence rather than in the latter. Such subjects are: Aborigines; Ecclesiastical; Education; Estimates; Land; Legislative Council; Port matters; Public Service matters. Copies of outward letters are present. No volumes are known to be missing.
