s Upper Shore-line. 
Red Crag with two large blocks of Coralline Crag, the larger may weigh more 
than a ton. 1 must have fallen before and 2 after the deposition of the bed r. 
There were also many smaller blocks, some bored by Annelids, others covered 
with Balani; as well as flint-pebbles, coprolites, and unworn flints.

Section in the Pit near the Barn, at the Western Part of the Ridge, 
Red Crag with many blocks of Coralline Crag, and here and there flints and phos- 
phatic nodules. Showing the section of the lower shore on the western side of 
the reef. “ The occurrence of these transported blocks of Coralline Crag is 
peculiar to these pits.” 
The occurrence of an eroded and bored surface of Coralline 
Crag at the Bullock Yard pit was first pointed out by Lyell, who, 
as far back as 1839, speaks of a buried cliff eight or ten feet 
high and in places slightly overhanging,* 
Prof. Prestwich’s further observations show that there are two 
submerged cliffs, that they pass round the hill, and that the mass 
of Coralline Crag, forming the higher part of the hill, has been an 
old reef in the Eed Crag sea.”t The section in the Bullock Yard 
pit was still open when I last visited it, but the old cliff "was 
becoming much obscured by talus and rain-wash. The Red Crag 
in this pit is of the usual character, and is referred by S. V. Wood 
to the upper division of the Red Crag, or to the same zone as the 
Crag at Butley. 
Prof. Prestwich has figured a section at Ramsholt, showing 
erosion of the lower beds of the Red Crag before the deposition 
of those above; this also is here reproduced, through the kind¬ 
ness of the Council of the Geological Society (Fig. 20).
