A series of physical and geological maps of the colony were exhibited, together with sections and plans illustrative of the gold and coal mines and other mineral resources. As evidence in support of these was a collection of rocks, minerals and fossils, numbering nearly 3,000 specimens, with catalogues, reports, and monographs, on the various branches of the subject. The collections were very carefully studied by a jury of scientific men, and their report will appear in the official records of the Exhibition. The collection was awarded a first-class certificate and a silver medal. The preparation of these exhibits required the expenditure of much time and labour, but this was warranted by the opportunity which it afforded of bringing prominently before the public the results of the scientific investigations which have been made of the resources of the colony.
