Excerpt from Tenth Annual Report of the Geological Commission, 1903 The work in the Hay Division has proved that volcanic activity played a very important part in that area both before the Black Reef series was laid down, and after the period represented by the Griqua Town beds. Very good evidence was also obtained of the prevalence of glacial conditions in that country during the deposition of the uppermost part of the Griqua Town beds, a welcome addition to the accumulating evidence of cold climates in extremely remote ages. Unfortunately, no further information towards the correlation of these northern rocks with the established European and American Palaeozoic or older beds has been found. The visit of the British Association in August was an event of no small importance to the Geological Survey. The discussion of many questions relating to South African Geology with geologists of wide experience in Europe and America, and the opportunities of taking them over some parts of the country, were very keenly appreciated, and were of material service to our work. During the present year a coloured sheet representing the geology of the south-western corner of the Colony on the scale of inches to the mile will be published, and it is hoped that other parts of the Colony for which the data are now ready will be Similarly treated before long.
