"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]
