The greenish colour of the sand and the hardness of the fossils 
in the lower part of the Crag is very marked. These characters 
are always found when the strata are met with at depths beyond 
the reach of percolating surface water. The buff or red colour of 
ordinary sections of Crag is misleading; unweathered Red Crag 
is green or bluish. While on this subject it may be well to note 
a very similar section at Saxmundham, recorded by Mr. Dalton.'*' 
Well at Messrs. Waller s Brewery, Saxmundham.

The well-known Bulchamp Pit ” lies about four miles due 
west of Southwold. The section there is now overgrown, but the 
pit was so interesting that Prof. Prestwich’sf account has been 
reproduced. He observed that some years since, a section 
nearly 20 feet deep was well exposed.” (Fig. 24.)

(Prestwich. Quart. Journ. Geol. Soc., vol. xxvii. p. 344,) 
In appearance and colour the pit is precisely like a Red- 
Crag pit; and it will be observed that we have here a repetition 
of the marks of erosion which we have noticed between the two 
divisions of the Red Crag in the Sutton district; or it may only 
be an eroded shoal in the lower division, as at Ramsholt” (see 
pp. 95, 96). The list of fossils, however, shows no trace of any 
horizon below the Norwich Crag, the 46 species mentioned by 
Prof. Prestwich being all Norwich Crag forms, and including
