Foracious shales smelling of petroleum predominates and then appears a blue-black impure or sandy limestone of [illegible] thickness that has scattering fossils of great interest. Did not have ample time to collect and it is exceedingly hard to get good prints out of the shaly weathered surfaces. Nautilids are common, goniatites are rare, Bellerptra-like crassus common, and elongate form is rare, and as were brachiopods. Are for too good Phillipsia. One curious feature of this limestone are several hummocks that rise from one to 4 feet above the general level of the [illegible]. They are made up of comminuted fossils (see sample) and around the edges are many Bellerophon-like encrustations. Also got one large shark's tooth. 6th Below this li. there are 8 foot of black shale, and then 3 feet of shaly black li, followed below by 4-foot shaly black shales and then at the overlying edge another 2ft-3 ft of blue-black limestone. I had no time to see if these have had prints. The Marble Falls li. was not seen down where the limestone at the waters edge crosses it. [Bean says it appears a little fourth down stream and in the bay you appear about miles] Are then over on to a place between 2 1/2 to 3 miles S.E. of Bend beside the old marino gauge railway that bring out Cedar ports and from Lampasa.
