RED AND NORWICH CRAGS. 
In the talus was found a fish-bone, fragments of Mactra, 
Trophon antiquus, and Pur pur a lapillus. 
Continuing northward a pit near Wroxhain Park, situated to 
the east of the Hall near the farm-buildings, showed the following 
section :— 
Feet. 
Upper Crag 
Chalk with flints. 
■4. Sand and pebbly gravel - 
3. Shell-bed (impersistent), sand 
2. Laminated clay and sand-

In bed No. 3 Tellina halthica is found abundantly, and it is 
also said to occur in No. I. Prof. Prestwich considers that the 
clay. No. 2, represents probably the Chillesford Clay, but it seems 
unsafe to hazard the identification of so thin a seam. 
East of Wroxham the surface of the Chalk sinks beneath the 
marsh level, and as it sinks the lower part of the Crag also 
disappears, and there is an indication of the tendency of the clay beds 
to thicken towards the east—as we find in so many other places. 
The brickyard east of Wroxham Station displays a thick mass of 
laminated clay and sand, which is used for the manufacture of red 
bricks. The section at the northern end of the pit showed the 
following beds :— 
Feet. 
Warp - - - - - -4 to 5 
"^False-bedded sand with seams of gravel, and 
irregular seams and streaks of laminated 
clay, fragments of carbonaceous matter, 
ironstone nodules - - - - 8 to 9 
Upper Crag -<( Very micaceous, greenish-grey, laminated 
clay and sand, having a wavy appearance; 
in one place let down probably by dissolu¬ 
tion of Chalk beneath - - - 18 
Eed sand and gravel. 
At the southern end of the pit the beds were overlain by 3 or 4 
feet of brown Clay and Gravel, representing probably the Con¬ 
torted Drift. Mr. Woodward was unable to trace the laminated 
clay further east, and it tapers away westwards through Belaugh 
parish. This section will be again referred to in the next Chapter. 
In the lower part of the valley of the Bure the upper portion 
of the Crag Series is exposed over a wide area; but as the pebbly 
gravels are unfossiliferous, and probably newer than the mass of 
clay at Wroxham, they need not be described here. We will now 
mention the more important exposures in the higher part of the 
valley, between Wroxhain and Aylsham. 
The first of these is at Belaugh, where shells are met with in 
an excavation by the side of the hill, near the Farm buildings, 
about a quarter of a mile north-west of the church. The following 
is the section, the lower part of which was opened up in 1877 :—
