Theposition of all the boreholes with regard to the boundaries of the field andthe railway is shown on the accompanying plan. The coal obtained from the main seam by drilling has been analysed andfound to be similar in general character to that obtained from the collieryand the bores to the northward. The chief point of difference between themain seam at the site of No. 6 borehole, and the more northerly portions ofthe seam concerns the distribution of the incombustible mineral matter inthe seam. In the area previously explored the cleanest coal lies at the topof the seam, whereas in No. 6 borehole the best consecutive samples over athickness of 6ft. are centrally situated in the seam. In other respects thecoal obtaine
