(See above) D As we once again into the Richmond the strata become more and more sandy, the hachis- [illegible] dry out, the Byrgon keeps on but the Trapostmatu dry out first leaving the minute forms to continue. Finally we gets into greenish sandy shales of considerable thickness with their characteristic luterine that have minute byrgon, astuerda, Jigospina accusvirrata and Lepiditius like caecijena. See my [illegible] fossils. Then come in a considerable thickness of red-brick-red shales devoid of fossils. All follow these and including them I call as if Richmond age. Then higher follows green sandy shales without fossils that may be from 44 to 5 feet thick. These are probably the introductory beds to the lower luterine of siluric age! At the top the shales change gradually into harder beds and these rapidly give over to say the bedded lithic green, finely granular sand or whome [Later concluded to refer them as Richmond]
