Notes on boring operations in search of coal in Tasmania

The attempt which is being made, by means of the diamond drill, to test the question of the existence of deep lying seams of coal at Tarleton, on the Mersey, and near the Cascades Brewery, at Hobart, calls for some notice. The work is not yet so far advanced as to demand more than a brief statement of the circumstances under which it has been undertaken.
For the basis of a provisional classification I will take the succession of rocks composing or associated with the coal measures of New South Wales, with which Tasmania has more in common than with any of the other Australian Colonies. The following is a rough outline of the order in which they occur: Triassic, Permian, Carboniferous.
