creeding was seen. The evidence Hovren says all
is for shallow waters for delta, and perhaps all
of the marine side but near the estuarial part of
the delta.
Near the middle of the Stanley are coal flecks
stales and coal black cherts that remind much
of the Fordfnd. Hovren strongly believes that this
is the equivalent of the Fordfnd and if so it
casts a new light on the age of the Fordfnd
and explains why geologists have stated the absence
of the Fordfnd in the Ouachitas. Much
Koell shale recurs above in the higher Stanley
formation.
Thin beds of coal recur near the top of the
Stanley in association with the plants. These beds
are very thin, perhaps in thickness, and of short
lengths. There are however many of them.
The Jackfork is mainly a sandstone deposit
with shale gneiss. Hovren says they are in every
way like those of the Pennsylvania. These beds
are replete with drifted plant fragments. Not only have

one inch in diameter, that he has seen Hallwell
