and to the overlying fine sandy shales. Because of
the incompetency of the beds, and the decided com-
petency of the Ormeulites below the Juedpark
above the Stanley is much folded and very
complicated. Against the Ormeulites the basal Hanty
is much older and metamorphosed.
The Juedpark because in the main of sand-
stones lies in broad open simple folds dipping at
low angles, probably not over 20 degrees.
At the base is the triplicate Arkansas
Ormeulite. The basal third consists of thin
bedded schistose hard and dense rock, that Berry
says is mainly made up of volcanic ash. This
is a very friable and breaks out in little concretions
of say Devonian completion. The lower third
has a thickness of 200 to 300 feet. The middle
third consists of thin-bedded material while
the upper third is the home-stone horizon. It
reaches to a porous material, jointed never
white or clay. This reminded one of the bird-
land cliffs seen on the Dolphin in October '20
but it seems did not see it any way.
The fossil? 976 a coal comes for the base
of the Ormeulites. If it is a coal then very
bare there are of the Arkansas ormeulites.
