From this point upwards to the fault, the beds are so dislocated
that I was unable to determine their true sequence.
2. East of Watchet. — The second section, about a quarter of a
mile to the east of Watchet Harbour, between high- and low-water
marks, shows the higher beds, which I failed to make out to the
west.

At the base of the cliffs, and with a dip of 35° to the north, decreasing
further eastwards to 15° or 20°

it is a deep-red marl with but
few bands and spots of grey. In Watchet Harbour and Donniford
Bay it abuts against the Ammonites planorbis shales that have been
thrown down to the south.

are very much indurated.
Black shale.
Grey and red marls in nearly equal proportions.
Grey indurated marlstones and black shales, with but two or three
faint bands of red.
The latter of these, representing the fossiliferous beds F and H of
fig. 1, yielded no fossils, perhaps from my being unable to devote so
much time to its examination as in the former case. But its barren-
ness was amply compensated for by the richness of the strata above
the bone-bed.
