and reddish brown sand, coarser than the sand which locally under- 

 lies it, and containing angular flints and many flint pebbles. This 

 did not lie in eroded hollows, but was evidently incorporated in 

 the Boulder-clay. The sand was slightly indurated, and, in dry 

 weather, it had separated from the Boulder-clay, and broken away 

 in smooth dogger-like masses, which, however, merged upwards 

 into the loam or decalcified Boulder-clay. (Fig- 1.)

Near St. Bartholomew's Church, at the junction of the Boulder- 

 clay with the underlying buff sand, a thin pan of ironstone 

 occurred, and here and there fine chalky detritus was present in 

 the sand. Buff sand was also incorporated at the base of the 

 Boulder-clay, while the portions beneath, to a depth of two feet, 

 showed distinct evidence of disturbance. (See Fig, 2.) The Boulder- 

 clay here contained septaria, ironstone nodules, and Jurassic fossils, 

 also fragments of Red Chalk.

South of Hopton there was a cutting in Boulder-clay with here 

 and there at the base coarse sand, which was slightly indurated at 

 the junction and merged downwards into fine current-bedded buff 

 sand. This coarse sand was stained red and precisely like the 

 masses elsewhere incorporated in the Boulder-clay. Here, again, 

 the sands below the Boulder-clay were distinctly contorted, and in 

 places where the junction was less even. At one spot the sand 

 contained scattered pieces of a broken ochreous band. (Fig. 3.) 

 Elsewhere, between Boulder-clay and sand there was a layer of 

 unctuous clay and loam streaked with chalky detritus. 



North of Hopton the cutting showed 10 feet of sand and gravel, 

 and beyond Kennel House brown and white sand belonging to the 

 Middle Glacial Drift, overlaid by 5 to 8 feet of angular and pebbly 

 Plateau gravel. This gravel was bleached and contained many 

 unworn flints, as well as pebbles of flint, quartz, etc.
