A BOUT half-way between Hayburn Wyke and Cloughton Wyke, 
and five miles North of Scarborougli, a scar of bard sandstone, 
reraarkable for its even bedding, may be seen rising with a con- 
siderable dip from the sea. This sandstone contains along its 
bedding planes occasional thin layers of a very dense ironstone, 
from wliick it has probably received the name of “Iron Scar.” 
Tmmediately beneath are about five feet of shales closely resembling 
those of the Middle Lias, and containing two bands of dogger 
ironstone. 
A careful search shows tkat the uppermost of these two bands 
contains a few small fossils ; while the base of the sandstone con- 
tains casts of Nucula minima ? in great numbers. 
This particular bed of sandstone would scarcely attract much 
attention, but for the fact of its constant presence in the great mass 
of false-bedded sandstones which wedge out in both directions in 
the face of the bold clitfs of this district. It can easily be traced 
from the above-mentioned locality to Blea Wyke and the great 
Peak fault, between which points it is seen about 160 feet above 
the Dogger, or top bed of the miners, and about 130 feet below the 
Millepore bed. 
It is not seen again in the cliffs tili we reach Hawsker, and it 
first comes to the face of the cliff immediately on the North of Maw 
Wyke, from which point it continues to High Whitby, and after 
turning inland for a short distance, once more reappears just North- 
west of Saltwich Nab. From this point it continues to the mouth 
of Whitby Harbour, wkere it is the capping rock of the East Cliff. 
In all this long exposure, though the bed preserves the same 
lithological appearance, it contains very few fossils, and would have 
remained unnoticed perhaps, but for the fact of its far better 
development inland. At Whitby its only remarkable feature is the 
sudden development of a false-bedded conglomerate in the midst of 
the sandstone ; a condition which can be well seen on ascending 
the Old Churcli Steps on the East Cliff. 
Inland we have to go as far as Goatldand on the Whitby and 
Pickering Railway, before seeing the typical section of what, in 
spite of its thinness, we believe to be an important marine bed in 
the great Estuarine series of East Yorkshire. 
About 500 yards down the stream, Eller Beck (from which we 
propose to call it the Eller Beck bed), below Goathland, and a 
little below the picturesque village of Darnholm, is a small Force of 
about seven feet fall, the Force being caused by a close-grained very 
hard sandstone, well bedded and flaggy at the base, and passing 
insensibly into a sliale, identical in appearance with the shales of the 
Ironstone series of the Middle Lias. The following is the section, in
