Friday July 8 Rinchy Cote. As we could but sail Forenkfel and I spent the afternoon walking along the Reid Manor gauge railway to the east of Rinchy Cote. One mile east one comes upon a group of maroon roofing slate that may be several hundred feet thick. It is undulating by & quartzite and overlain by more quartzite - conglomerate. Further down into the Hunter river one meets with great masses of slate greenish to black. Then groups of sandstone occur along with arenaceous dolomite. In the Hunter valley we saw a pinnacle dolomite. All of these strata have been subjected to great pressure and all are metamorphosed more or less than the slates of the Hudson Valley. Cleavage is well developed and as a rule conforms with the bedding though in places the cleavage lines pass through the groups of lentic shales. In all of the harder beds one sees quartz veins of all signs and running in all directions. In the shales one sees little of these veins and as a rule only where the sandy beds are present. Just as one enters into the gorge of the Hunter river comes upon its very thick ancient delta. The top of which above the railroad is fully 100 feet high. In other words the Hunter arm in case probability runs 100 feet deeper than it is now. The sand and rounded boulders of the delta lie at a steep angle dipping into the Hunter Arm.
