34 on Devils herb hill of Youngs Point as far as the S.E. corner of 5.25.4 seen a series of dark grayish slate shales in the middle of these and they strike N.85W. and dip 45N.E. and contain an abundance of fossils: 5.25.4 A, chiefly Dalmanella (smallish) common. Trilobites Neurocrania (2pp.) occasional? Type type. The shales are red slotted and are well laminated. Near the south end of the shales appear an abundance of large boulders of slate with limestone bands 3 to 5. miles N.W. from J. fossils. Some of these specimens which appeared from slate strike N.55W. and dip N.E. about 40o. They count 5.25.4 A' chiefly abundant Dalmanella Cornaro-cochia acut. Daly's, 1913 is the (and quite a few) one, The fossils collected were not in place but appeared lying loose Underlying 5.25.4 A' are some hard gray tuffs with thin & close on Devils Point but they are not certainly in place. The point in N.W. 5.25.8 or Jabori. The upper part of the shales near Youngs Point are full of (5.25.4 B') Acmastrelllla abundant Nuculites (?) small nodules in outline) com Neurocrania 2pp. com: Archeolyda R They have strike N.20W. and dip N.E. about 40o Between 5.25.4 A' & the shales are cut by an intruded sill of amygdaloid basalt trap, and by a natural like lead gray shale silite trending W.S.O.S The dark band of phyllite appears has a dip as the S. end of the exposure of shale. 5.25.4 A-B clearly marked along the feet are exposed sunk against the S side of Youngs Point in a fault plane trending WN23O.S The shales are buried sheared near slantely? In the east side of Devils Point in this restricted group of the little bay in 5.24.6 occur the same phyllite as well found on the west side of Devils Point (see) The phyllite bed is not intruded into course trap (1250) and is islanded on the east by the trachyte tuffs, its cany 5.24.6 A' blue tuff strike N 62W. and dip 45N.W. was also seen over some 12 or 13 feet of shales intercalated with the tuffs and surrounding it about 25 feet wide. The lower half of shale clayey are thin, papery and contain rare specimens of Trilobites (detected) as 5.25.4 B') and a Dalmanella 5.24.6 B' In the middle of the shales (lengthwise) there are less paper and appear in occasional fragments of slate and a seam provided with Alacrispira - 5.24.6 C'. The upper 3 or 4 feet of shales are - thick slabby laddle and some dark ashlar seams full of fossils for 100 ft. They are also sandy grades up into the underlying tuffs, see Jabori 5.24.6 D' underlie.

Around the Point occur red tuffs apparently base alternating with light gray apparently acid tuffs. The kind in this slope like coal near up the N.E. end of Devils Point seems phyllite between slate sim- silar to 1250 Road trap occurs a few rods, to the S.E. In this N.W. - very red layers are intercalated in the grayish light colored tuff which crosses Devils Point and has specimen no 12-5/13, a light gray 1250
