The three organizations responsible for this progress are (1) the Coal Survey, whose activities are mainly geological and chemical; (2) am organization set up by the Mines Department to follow up the Coal Survey with detailed topographical surveys and shallow prospecting by meansof cuts, pits, and hand drilling ; (3) the Drilling Section of the Mines Department carrying, out investigations by percussion and rotary drilling. As a result of the intensive work of these organizations during the past four years considerably more information is now available than was the case in 1946 when the lastestimate of the coal resources of New Zealand which appeared in the Mines Statement for the year 1945 was made. This matter has lately been considered jointly by officers
