est, and the weight of evidence here seems to be in favor of 
West of the limestone bluffs (not included on the map); shaly 
layers, strike N.:25° E., dip 35° to E.S.E. 
N. 35° E., dip 15° S.E. This variation of position is not sig- 
nificant, for equally great variations are found in the limestone 
itself in passing short distances along the cliff face at many 
oints. The cut here reveals a considerable depth of talus 
Tagments, often including large blocks that might be taken for 
ledges in place if not fully exposed, and show how difficult it 
Would be to find a natural contact underneath the bluffs.

In the bluffs, a few hundred feet south of a glue factory; the 
Tentaculite stands N. 28° E., dip 15° E.S.E., at base of lime- 
Stone outcrops, and about twenty feet from it the shale appears, 
but unfortunately shows nothing but cleavage, N. 25° E., dip 
00° E.S.E.; however tempting it may be to assume that the 
cleavage and bedding coincide, there is not the least evidence 
that they do. The steeply inclined splitting of the horizontal 
Canda-galli shales within the limestone synclinal shows how 
entirely untrustworthy this appearance may be as a guide to 
the position of stratification. On the road-side, about half way 
from B to C, the bedding was N. 25° E., dip 30° E.S.E. 
. a mound on the northern side of the entrance toa 
deep valley near the southwestern end of the mountain. The 
limestones are here nearly horizontal; no contact is found, but 
about forty feet down the slope from the lowest visible layer of 
the Tentaculite, there are numerous small outcrops of a very 
uneven, indurated, flinty rock, for which no position could be 
determined satisfactorily. Its irregularity would, however, 
Indicate unconformity. Similar small patches of indurated 
Slaty rock, from which the bedding has disappeared, are found 
near the road on the other side of this valley.
