3. “On the Search for concealed Coal in New Zealand,” by J. C. Crawford. Abstract. The writer suggested that search should be made with the diamond drill for concealed coal measures, which were overlaid by tertiary formations, in the valleys of the Wanganui, Wangaehu, Turakina, and Rangitikei rivers, at spots which the Geological Department might point out; also that the eastern side of the dividing range might also be examined, though the borings at Poverty Bay should give an indication of the strata. Dr. Hector did not think that the suggestion was of much use without indications of the best localities, as it would not be a very wise proceeding to bore at random where there was perhaps 2,000 or 3,000 feet to bore through. Mr. J. C. Harris suggested that Mr. Crawford might have thrown out the idea for the benefit of future generations. The surface deposits on the West Coast and in Auckland were known to be so extensive that the colony would be amply supplied from them for at least five or six hundred years. These must be nearly exhausted before any boring operations for concealed deposits could be undertaken with profit.
