"We are all more satisfied that the most intense
orogeny of the Silian [illegible] took place after Teonius.
Simple time, but the age of the Teonus is not for
known. Then after a time of erosion the area
was invaded by the Pennsylvanian sea later
Canyon time and continued unbroken through the
Baptist time which means to close of Civer.
time. Both the Lower and Upper Baptist are
folded alike, though the latter appears to be less
folded. What the relation of the wringing Wolf-
Camp is is not yet clear further than that it
appears to be conformable though separated by a
marbled or similar uneven formity. Therefore the
second folding may be post Upper Baptist and
it may be Post Permian (probably at the close of Permian).
In any event there is a marbled break between
the Baptist and the Permians. In some places
there is Wolfcamp and in others either the other
in Leonard comes to rest on the Baptist. To-
omorrow we will learn more about this second
time of orogeny.
[Later one concluded that Teonus-Dimple is post-
atly = Upard Lower Baptist, and that all were folded together
at the close to Penn. = Up. Baptist = Civer time]
