As will be seen by referring to the 

 Geological-Survey Map (New Series, Sheet 

 249), the road bends about where the sec- 

 tion depicted in fig. 2 was taken ; and there 

 is a rather sharp curve near the faults, 

 which accounts for the apparently-high dip 

 of the Eed Marls. 



In the steep hill near the Milton Hotel, 

 certain Hhsetic beds are exposed. The 

 Cotham-Marble equivalent here is a smooth- 

 textured limestone with faint ' arborescent ' 

 markings, and in the uppermost layer a few 

 fish-scales were noticed. The Esthei-ia-Bed 

 was observed as a hard nodular limestone, 

 withimperfect 'arborescent 'markings; while, 

 near the foot of the hill, the basal tlhgetic 

 sandstone crops out. The same bed is well 

 exposed in a shallow road-cutting, about 

 three-quarters of a mile north-by-west of 

 Llanwern railway-station.
