not collected but seems as 3:32.6a the section runs continuously up into 3:32.6a and underlying beds see 10.14 & seq. 3:33.7 & V F are really in 3:32.6. Tuesday, July 16, 1907 BIRCH POINT Passing along the east side of Birch Point northward we find the basic tuffs along 3:51.8 followed by a ginnaceous coarse trap or gabro gelose which lies buried through some flags & shales taking the latter zonolith. About 12 feet of gray shales & thin bedded lags are posed nearly horizontally along a low beds cliff to the north base of the hill along the boundary between 3:51.5 (s.w. corner, including all the s.w. rocks) and 3:51.4 (s.e. corner). These flag & shales shut off large intermasses of coarse trap & gabro which is exceedingly amigdaloidal & ginnaceous flags & shales only for yards wide. Contact N 70° W in my northerly portion running around to s.e. in lower part forest very scarcely, rocks = 3:51.4-5 a. include or occasionally scattered lingulae (H. Huxhall Head beds); there are a few -dim layers of calcareous tuffs which contain masses of shells chiefly ligust. the flags are more marked and fern racks are also common in zone. The ginnaceous amigdaloidal trap cutting 3:51.4-5 a is [illegible] 2.55 m in its usual place of the same rock as 10.15. Jossels were found in the basic tuffs west of the deep rose west of Birch Point. Jossel found as called 2:55 & K [illegible] but really 3 m in sand on the shore 3.60 W of the little 10 foot contour circle. The fossils occur in the finer grained sand portions (2:55) m and in a calcareous lignite made of shells embedded outside rocks not out in the water.
