The upper part of the Preglacial Cromer Forest-bed 

 is here represented by a mass of peat filling a shallow 

 channel. It is full of remains of animals and plants, but 

 the latter are not usually well preserved, and have not yet 

 been properly collected. They seem to include a some- 

 what larger proportion of dry-soil species than is usually 

 found in deposits of this age.

The plant-bearing strata yield a Temperate flora, but 

 contain at their base far-travelled erratic blocks, derived 

 from an earlier glacial deposit, and are overlaid by brick- 

 earth of Late Glacial date. The plant-bed corresponds 

 with those at Selsey and Stone, and contains remains of 

 Elephant, Rhinoceros, with some freshwater shells no 

 longer living in Britain. Local conditions being excep- 

 tionally favourable, the flora is unusually varied, fresh- 

 water, estuarine, sea-coast, marsh, dry-soil, woodland, and
