cylinders are red shale completely filled with nodular chalk from nodules some of which are small limestone. They are all sizes from 1/2 inch up to several inches and often they are so abundant as to coalesce and form lags. All of these nodular pieces are apt to weather greenish giving me the impres- sion that copper salts are present and they are or abundant in Ellis shale, just above thick division 7 is at Orcheston Cape I did not ascertain but it did not appear to ore to be thicker than 100 to 200 feet. Below this division 7 follow a great thickness of sandy brick red shales at the top of which the (The crusty clay we did not see these at the contact above Standbridge) lime nodular gries are particularly abundant. Lower down the seems to vanish but one did not go far enough south to prove this. No fossils occur in these nodules of limestone and chalk from nodules. The sedimentation is quite regular and while we gets the idea that they are continental deposits with caliche gries I am questioning whether they are the deposits of shallow sea flats. We noticed nor saw cracking through the outcrops once not favorable to see them. These brick-red sandy shales appear to be in Lyons division 8, see 2 photographs.
