into two structural parts. These parts are respectively Crag pos- 
sessing none of the characters of a deposit formed under water, 
and Crag with the usual characters of a water-deposit. There are 
to be observed in.one pit at Hollesley (see woodcut infra) four 
Pit near Hollesley. 
North end of pit, looking N.W., fourth and fifth stages. 
{This section is in its true vertical position 
relatively to the section below.] 
South end of pit, looking N.E. Three Beach stages. 
distinct stages of the first-mentioned Crag, one over the other, 
covered partially by the Crag with the character of a water- 
deposit ; and in consequence of that quintuple exposure, I shall, 
for convenience, distinguish the one division as the beach stages 
of Crag, and the other as the fifth or horizontal Crag. 
Of these beach Crags the three inferior stages are not alto- 
gether constant in their direction, although, where exposed, they 
have for the most part a distinguishable uniformity of direction 
in the inclination of their planes of stratification. There is only 
one other section (that at Brockstead in Sutton) where so many 
successive beach-stages are exposed. The less frequent exposure 
of the more inferior stages, or at least of the two lowest, and 
the extent to which they have suffered from the denudation 
consequent upon the formation of each succeeding stage, render 
it difficult satisfactorily to divide any of them, except the upper- 
most, into stages capable of identification with each other at 
every exposure. This, however, is not the case with the fourth 
or uppermost of the beach stages. From the great thickness 
often exhibited by this stage, and from the more partial denuda- 
tion by a succeeding stage to which it has been subjected, this 
fourth-stage Crag presents the means of accurate identification.
