You are as well aware as I am of the extreme difficulty of following out any particular bed in the Australian coal measures in consequence of the great variableness of their condition, a remark which applies so generally to all members of the carboniferous (now dated as Permian) formation in N.S.W., that it is not safe to trust any of the rocks further than you can throw them (see Moyal 2003).
