6 degrees west-north-west. I traced it on both sides of the valley, and followed it also in other directions where transverse valleys have been cut through it. The following is an analysis:—

It may be as well here to add that the analysis of both coals was made upon surface specimens, which had been exposed for probably an indefinite period, both to the action of the atmosphere and to that of water, so that we may expect, on getting into the seam, that the amount of carbon will be found larger. The valley where this coal seam occurs lies 1914 ft. above the level of the sea” (We may add here that subsequent research has not only revealed other seams of coal besides this, the first discovered in the Buller district, but that experiment has corroborated Dr Haast’s opinion that the coal possessed higher carbonic value. Readers are referred to the official records prepared by Dr Hector, the Government Geologist, Messrs Cox, Dobson, and others.)
