In reporting some of the most interesting results of the labours of the Geological Department since last meeting, Dr. Hector said that there had been upwards of five hundred analyses made in the laboratory, and the results of each had been entered in a book, which was open for inspection by members. The principal analyses recently made were of samples from the large deposits of brown coal which had been found in Southland. This coal occurred in seams of great thickness, being in some places over thirty-five feet thick; and though it was inferior in quality to the coal on the West Coast, it would no doubt prove of great local value, and perhaps be extensively
