188 Mr. S. V. Wood on the Red Crag ° 
Pit at Crag Hall, Tattingstone. 
Three Beach stages. 
In one place only (with the exception of a bed peculiar to 
Walton Naze, and presently referred to) could I find any indi- 
cation of a water-deposit. This section is at Butley, near the 
Abbey: a bed is there exposed, underlying a true beach stage, 
more sandy, and stratified in a peculiar elliptical manner, resem- 
bling the grain of wood where knots have been cut through ; 
and it appears to me to afford indications of having been pro- 
duced in a very shallow eddy. Nothing also is clearer than that 
this inclined stratification, which at first sight resembles hori- 
zontal strata tilted by upheaval, is due to no elevating action, 
as, independently of the great area over which the fourth stage 
extends being inconsistent (on such an hypothesis) with its 
limited thickness, the inferior stages on which it rests often ex- 
hibit a less inclination than does the overlying fourth stage. 
At Walton Naze, however, underlying the fifth stage and 
two subjacent beach stages, a bed of Red Crag occurs, lying 
on the London Clay, which differs entirely from any other Red 
Crag known. It is destitute of stratification, and is of a greyish- 
brown colour. It alone, of all the Red-Crag beds, yields shells 
in the condition in which they died—bivalves not unfrequently
