In the Forest Marble the beds vary considerably, both in thickness 

 and in character, when traced from one end of the quarry to the 

 other : this may be, in reality, due to false bedding, which would be 

 almost obscured if the direction of the currents were at right angles 

 to the general trend of the section. The section is as follows : —

1 [Since the above was written, the quarry has been greatly deepened about 

 the centre, and a pit has been sunk, with the object of draining off the water. 

 The following addition to the section was noted (September 1913) : — 



Bed d. False-bedded limestones and clays about 8 feet. 



Bed e. Irregular oolitic marl and limestone, slightly false-bedded. 9 to 15 inches 

 giving a total thickness for the Forest Marble of 21 feet 3 inches. 



The Great Oolite section is as follows : — 



Blue-hearted limestone (= Fossiliferous Cream-Cheese Bed)... 2 feet 2 inches. 



Dark bluish-green clay 4 feet. 



Brown marly band with plant-remains about 1 foot. 



The section was carried down about 11 feet below this, the sequence being 

 similar to that exposed in the Lower Green-Hill Quarry.]
