October 20. Monday, Lelfham.
A dark threatening morning, but we are in
in Ardmore at 8.30 A.M. It is about 35 miles to
Ardmore. By nine o'clock the indications are for a clear day.
Five or 6 miles south of Lelfham we see the first
deformed strata of the Ashwood, the Brodfield chalk. Here
beside the road at the crest of a hill the strata dip about
30 degrees to the north consist of a series of white shales (with shales
of lighter green or lighter pink) with thin goss of some flint cherts
(2 to 4 inch thick). Small flint chert nodules occur in the shales.
Other traces for fossil are seen. In the stream near by the chalky

of the tract gives a
A little to the north of the Brodfield chalk exposures at this I
saw the Lominite conglomerate. This conglomerate varies all the
tide formations and its character depends upon the underlying
formation. Dr. Pleas, Bryon states it is all of limestone, Broad-
field chert, or other material.
About 8 miles south of Lelfham we turned into a
side road going past Chetro and then to the farm on
which is located the "White Orchard" of Helodotupian
fossils. I never saw so many fine fossils at
any locality before. Beneath the red clay conglomerate
formation occurs a third series of muddy left flint
limestone or calcareous hard shales in which the fossils
