mile. The dip is 60°, N. 50° W., with a somewhat higher dip 
down the slope. 
The fossiliferous limestone follows immediately. The first 
layer seems to conform with the wall rock. At the kiln, which 
is not fifty feet from the base, it dips 60°, KE. 5° S., and also 
westerly. Hence there is a small anticlinal axis. Directly at 
the kiln no fossils were obtained; they come from a dark 
layer with a westerly dip nearer the brook. The Zaphrentis 
and the Favosites with small crinoidal fragments are found here. 
Geologists have searched for fossils at the kiln, and finding 
none have concluded that our story about them is a myth; bu 
they should look in the right place. Dr. C. T. Jackson visited 
this kiln in 1841. He says: “The bed is included in mica 
slate, embraced on both sides by granite, which crowded the 
limestone in such a manner as to produce contortions of the 
strata. The course of the limestone, as indicated by strata 
marks, is N. 20° E., S. 20° W., and its dip is to the northwest.” 
He figures the bed as enclosed between two masses of granite, 
but does not exhibit any contortions in the strata.* 
uvium of Parker Brook intervenes and conceals the 
rock for an eighth of a mile perhaps. On the southwest side 
there are several outcrops of limestone—some of them contain- 
ing coral masses. A slaty mass with no cleavage is mixe 
with it. The limestone near the first house on the west side of 
Parker Brook is bluish, and was at first supposed to belong to 
the Lisbon series—as it is not fossiliferous. It has been exca- 
vated for a kiln in years gone by. Recent researches indicate 
southwest, where the Pentamerus is found. The mingled slate 
and limestone extend up the hill and then across the ndge. 
The chloritic rock re-appears on the section at a fork in the 
, and continues uninterruptedly for three-eighths of a mile, 
of about 1,900 feet of strata. This is undoubtedly continuous 
to the west end of fig. 2 in one direction, and to the slate quarty 
in the other, a distance of about three miles.
