Muskogee, Wednesday, March 26-1919 Set out at 6 A.M. and we are off at 7.15 for Fort Silsbee via a trolley line 8 miles N.E. of Muskogee. Then we had a Ford take us by Fort Silsbee (an old abandoned army post) to a place about 2 mile north of the trolley station, on the banks of the Grand River also known as the Merchoke State on the H.L. and S.F.R.R., at the sign post Keough there is a large quarry where Mr. [crossed out] crosby [illegible] G.C. Schneider, collected all the morning in the Monon formation above the Archimedes or Mays formation. The great majority of my fossils come from the upper part of the Monons. After collecting this morning seeing all the fossils here I can see nothing of Pennsylvanian age, and all is to me rather suggestive of Chester. This Monona fauna has nothing in common with the Poland of Texas, and seemingly with the Monons described by Mr. Mather. On the surfaces of the limestone beneath the third Rock shale occurs two species of Pentamerites, [illegible], Drickelman, and the greater profusion of byssoora. The Pentamerites go up into the Hackle shale. In Schneider report on this area he calls the Kemp quarry the Petkin formation.
