334 ME. W. HILL ON THE LOWEE BEDS OP THE UPPEE 



there is an absence of the mineral grains which characterize it at 

 Hunstanton and through Lincohishire. 



The section is now somewhat obscured by weathering and b}' the 

 facing of the embankment. Messrs. lliddlemiss and Keeping* 

 give the following as the section, taken probably at this point : — 



ft. in. 



Nodular red chalk 1 6 



Pale nodular chalk 1 3 



Clayey red chalk 6 



Grey nodular chalk 1 



Eedchalk 3 



Yellowish-green clay 9 



Unctuous red clay 1 6 



On the brow of the Wolds, to the south of the railway, the same 

 yellowish sandy-looking material can be seen beneata the Eed 

 Chalk. 



Proceeding northwards, a small section in the Eed Chalk can be 

 seen at Eudstone Walk, and the bed can be followed through New- 

 bald and Sancton to the north of Market Weighton, where, just 

 south of the railway, the Red Chalk, very conglomeratic, can be 

 seen resting on the ironstone and clays of the Lias f. 



In the valleys near Goodmanham are many small exposures, and 

 again at Londesboro' village, and in the valley running back into 

 the Wolds at Park Farm. 



The Eed Chalk continues to be seen " in the valley leading up 

 to WarterJ, . . . more particularly in the brickyard on the 

 north side of the Park, where, although the beds are much slipped, 

 the following sequence may be made out " § : — 



ft. in. 



Grey chalk 



Red chalk 2 6 to 3 ft. 



Yellow marl 1 



Lias 



At Millington Springs and in Beep Dale, just opposite the field- 

 path leading to Millington Grange, at Grimsthorpe and Great Given- 

 dale, the ruddy colour of the chalk catches the eye in many a small 

 exposure, or as fragments scattered over the brow of the Wolds, but 

 none of them afford a clue to the thickness or to the succession of 

 the beds above. Along the brow of the Wolds, between Great 

 Givendale and Garrowby Park, several small exposures occur, and 

 the bed seems to continue very conglomeratic, large fragments of 

 ironstone of oolitic structure occurring in it. 



In the Park, about half a mile east of Garrowby Hall, the foUow-

 have not seen.
