Serpulites sp. rare
Wednesday July 31, 1907 (A.18) collected from 5:3:8 F.
264 then the shales containing
the rich fauna 5:3:8 F as immediately underlaid by 3 feet of shales which are similar lithologically except that they are more bonded & i as taken by a three foot underlying trap shale.
These looked slates 5:3:8 G, also contain a couple of large seams and in one of these fossils were collected consisting of
Dalmanella (coarse) abund
Rhynchonella sp. rare
Chonetes denzeri sp. "
Syringopora? Clamipes) "
Strike N. 45° W. x S.E., dip 35° N.E.
Three shales as followed down and in the section following the section down and the three feet of laked slates 5:3:8 & about against a three foot trap dips which seems very nearly along the line of strike. This strike to 1/32 and bears N. 45° W.
Below the strike 1/32 is a covered material about 10 feet broad and then more thick crops out a calcar-
eve all in a foot thick containing fossils,
chiefly Hindia fibrosa abundant
Dalmanella coar.
Rtzia
Pteronotella n Actinopteria rare
Cornulites serpularius rare
This volcanic ash strikes N. 42° W and dips 35° to the N. 40°. The fossils are 5:3:8 H.
Thursday, Aug. 1, 1907.
Following the section continued as a covered trap below 5:3:8 H shales is "a covered top about 8 feet wide on the slope and then crosses a rocky point consisting of some thick slates of the base and top and a thick massive triff lacing in the middle. The upper shales are or four feet thick colors observed and break into large splintery chunks, bedding planes not well developed. These slates contain occasional spots with little ash fragments indicating that the period of volcanic activity represented by the underlying trap became extended sporadically. These overlying shales also contain large boulders mostly the same of the shales is 5:3:8 K and includes
Dalmanella (coarse) abund
Archeodesma (small). rare
Chonetes denzeri rare
Rhynchonella (? Rhynchotrema) common
Crinoids. occasional
Cornulites serpularius rare;
Mediolopsis & platyphyllus occasional

The Orthoceras is something as much as 2 inches or a little more
