The very unequal thicknesses of brown coal met with inthe various bores is accounted for, at least partly, by suchan original accumulation in basins. But it yet remains tobe shown to what extent irregularities in the coal beds aredue to wash-outs of the nature of erosion by the coal-forming period, which tracks would beafterwards obliterated by silts rendered highly carbonaceousfrom ligneous matter transported from erosion areas else-where. This and the question of a general erosion intervalat the upper limit of the lignite beds, with its bearing alsoupon the extent and distribution of the residual lignite arematters to be settled when the boring operations are com-pleted. • ?
