Notes regarding the existence of lower coal measures at Port Cygnet and Harefield.

Abstract

Geological description of the Mount Cygnet and surrounding areas also description of Harefield in the Fingal Basin. The coal seam of Mount Cygnet is worked by an inclined adit or drive on the northern slope, near the bed of one of the tributaries of Gardner’s Creek, and the coal is carried a distance of about two miles westward by a wooden tramway to the jetty at the township of Welsh, near Port Cygnet. The relation of the lower coal measures to the marine beds at Mount Cygnet corresponds closely to that of the Adventure Bay coal measures immediately to the south, towards which they dip.
