133 8:21:1:(A) Along the south part of 8:21:1, the porphyritic tuffs strike N.8. along a distance of 100 yards, altho small modifi- cations of a rod or so may produce localized modifications of strike. The dip is 28 degrees east. On the south side of the southern point in 8:21:1 occur some fossiliferous shales intercalated in the tuffs. The diagrammatic section above, normal to the strike, shows the tuffs followed by a covered area 66 feet broad, th n crop out for a width of 12 feet some layers of fossiliferous blue shales and thicker-bedded, calcaro- shaly or indurated layers. These are followed by a nearly cropped slice, 20 feet broad (for a couple of feet in this space crop out some very soft, thin, blue-grey shales which cleave vertically. They are full of poorly preserved fossils,-not collected- of the same fauna as 8:21:1.A. After this covered space follows a width of 22 feet containing light marine grey hard, non-fossiliferous shales. These underly more porphyritic Tufts 19pts. tuffs. These beds strike N.20-22 degrees E., and dip 27-28 degrees east. This gives a total of some sixty feet of shales between the tuffs. The fossils occur in several seams. 6 = 6 feet Hor.v vert.
