Abstract

I handed in the subject of this paper, intending to throw together various notes which have been accumulating for several years. I recently took a trip to the region under consideration intending to visit several localities and examine the borings of several wells, which, however, I was prevented from doing for lack of time. Had I been able to procure careful notes from all the wells I should be more decided on several points stated below.
