For convenience of reference, the subject is divided as follows:—

1. Introduction and sketch of geological structure.
2. Economic geology.
   1. Soil.
   2. Coal and oil shales.
   3. Sand.
   4. Clays.
   5. Building and ornamental stones, including cements.
   6. Gold.

4. Appendix.

I.—Introduction and Sketch of Geological Structure.

It is possible that while to the casual observer the geology of the neighbourhood of Dunedin might not prove so interesting as that of many other portions of the colony, still, for the general student, there are many instances of geological phenomena which would rivet the attention, and furnish ample food for reflection.
