About 5 miles north-west of Hadleigh, another outlier, in the 
Chalk Pit, marked on the Map, just south-westward of Monks* 
Eleigh Church, gave the section Fig. 12. Just to the left the 
Boulder Clay rests directly on the Chalk.

Section in Chalk Pit, Monks* Eleigh (about 25 yards long). 
(W. Whitaker.) 
N.N.W. S.S.E. 
a. Boulder Clay ; 4 to 8 feet. 
h. Coarse Gravel, at S.S.E., elsewhere only a trace, and finer; up to 4 feet. 
c. Bed Crag. Light-coloured sand, with iron-sandstone, ironstone (? cast of 
shell) and at the bottom flints, flint pebbles and phosphatic nodules, a piece 
of bone and several sharks’ teeth; up to 2 feet. 
d. Chalk with a few flints ; 12 feet. 
This is the furthest point to which the Eed Crag has been traced 
in a north-north-westerly direction. 
Bordering on the valleys of the Brett and Stour there are 
numerous outcrops of similar ferruginous beds, with casts of 
fossils, or only badly preserved specimens. These, however, are 
fully described in the Geological Survey Memoir on the Country 
around Ipswich,’* and need not be re-described here. They are 
principally interesting as helping to connect the distant outliers, 
just alluded to, with the main mass, and in themselves are of little 
interest. The pits in which fossil& are well preserved all lie east 
of this area. 
The most westerly of the well-known sections in shelly Crag 
lie in the valley through which the Eastern Union Railway passes. 
Mr. Whitaker thus describes the Bentley Pit.”* 
The large Crag pit at Danes Barn, just east of Bentley Station, 
shows more than 30 feet of false-bedded sand, in great part a grit, 
mostly ferruginous but partly light coloured, partly compact and 
evenly bedded, with layers of iron-sandstone and of ironstone (also 
occurring in concretions) which sometimes contain impressions and 
casts of shells in the upper part of the section. There are gravelly 
layers, with phosphatic nodules, as well as flint pebbles, one of 
which layers (near the bottom) contains a good many angular 
flints. The bottom 4 to 7 feet is shelly Crag, the shells ending off 
at top regardless of bedding, the bottom gravelly layer (which 
shows a slight northerly dip), being above the shells on the south
