40 Its southern margin trends S. 25°-40° E. On the south side of Red Point near the middle we see some ledge of dark red nodulated chales, covered or flung to. On the south slope of Red Point over the west and near some dark black block chales, similar to 7.23 A, turned up on edge and striking N. 37° E. there is a dip of about 85° N. W. These shales are thin luted very dark colored & excessively shekerded (poking group a sandy block appeared), they contain an abundance of Camellibrancha mediogypsa, Cyrtodonta and m. fortunately too poorly preserved to give any rule a Beyrichia I have found that actually is seen but evidently from these shales], the fauna 6.52? A places Head series - These shales, of which between 20 or 30 ft. occurs at this point be found in a mass of general shekerded trap excessively jointed much greens on both sides of the shales 6.52? A and forming the substrating belt of Red Point for over 110 yards long. [Both sides by an alephanized trap with the shales are cut by a 6 foot side of very amygdaloid of trap which trends N. 45° W.] thinned part of this top is a smooth plane along the shales are difficult slightly to the N. W. On the end of Red Point appears the red shales which give the point its name. these shales also continue for the southern corner of the point to the little indentation on the west side. the shales are massive, rarely a very seam or metwbed & along the strikes and a couple seams of small fragments of shells that they strike a dip at the northern end of the exposed shale, the strike N. 16° E. and the red shales dip W at an angle of 52°. on the greater portion of the length of exposure the shales strike N. 65° E. and are vertical from the N.W. and they appear to resume the N. 16° E strike just midway of 549. No fossils occur at the north end of the exposures of red shales on the south side of the little indentation that in the west margin of Red Point - a -- stay at ---- off, about 20 feet thick occur in the red shales. No fossils are found in the red shales such as I have seen in places full of amygdaloid like little smites filled with shells. On the north side of the little indentation in the west side of Red Point the trap reappears, in the south margin trending N. 50° W. On the opposite shore of Red Point the supposed shale for red series (Beyrichia or the west of the little shale level with a 3 foot sanding. The shales there contain some coral Cyptodonta & small fossils with occasional Beyrichia. By these we are much farther at the following Shale Hardy as I preserved, as indicated by fossil friends 41 surfaces the strike in the middle of the west part of this row N. 30° E., dip southward approximately 25° and this is also the strike and dip of the northwest end of the area where the shales may against the half closed seams almost trap which trend N. 35° E. In the middle of the exposure of blue black shale the strike is N. 75° E. and its dip southward for a short distance about 75 feet of outcrop are exposed in the west side of this little cove. The shales reappear on the east shore along little cove striking N. 65° E. and dipping to the S at an angle of about 20°. A few Camellibrancha (cyptodonta ?) nodosa [opera] occur here 6.52? C (not collected), in the tiny indentation at the north end of the little point on the northeast side of Red Point in the S.E. corner of the N.E. quarter of 6.52? occurs a greenish trap similar to the shekerded trap occurring along Red Point. A specimen is 1230. This trap reappears on the east side of the point and applies to as a general N.W. trending nearly S. W. The north end of this little point contains an important series of shales which stratigraphically resemble the preceding shales of the supposed black for head series. They are somewhat more ample mediogypsa? by th dentis - Camellibrancha appear eently the same as the other dark shales, but differ in two respects. One places is that they contain remains 3 inch centincher seams full of Platycerasma with apparently also some Prionoceras auriculata. The Cyrtodental to near a couple? Plens? Or shales from the entire fauna is 6.52? D. These shales differ from the shales not only in the occurrence of Platyceras & Gonnacres, in which aspect of the Gurnet Point shales, but they also have a different strike - uninterruptedly instead of north-southerly in the west side near 1230 the N. W. strike is N. 50° W./43° and on the top of the point at in N. 75° W./the average strike - N. 60° W., dip 30° S.W. Shekerded trap occurs in the cove on the southern side of Red Point. At the S.W. rock of the point on the west endy Casis Gun trap appears striking appear cally N. 50° E. x S. 50° W. & and the trap of Red Point. About 10 yards N.E. about about 10 feet of dark bluish black thin bedded shales, strike N. 45° E., dip 3° E. at 17°. No fossils found. these shales occur at half tide level in a tiny strip but a couple fude to the north the shales are red at c/ case & to take close for about 10 feet and strike N.W./8 (44)° E. dip past 24°. These shales dip under the trap which also cuts through them. The shales contain a Platycerasma seems as 6.52? D (not is collected) It appears to be just of shale and of a lighter grey color and these appear a general gray shales trap out under the trap on the north side & also little
