LOWER OOLITIC ROCKS OF ENGLAND : 
In parts of this area the Series appears to rest directly on the 
Upper Lias Clay, and where two clays come together, the well- 
sinkers are not likely to make a distinction. 
Prof. Green (MS.) has noted that, "between Calverton and Stony 
Stratford, thick-bedded white limestones, which must be very near 
the top of the series, occur in great force, and have been largely 
quarried." 
The Great Oolite at Linford Station, consists of fissile beds of 
earthy and oolitic limestone (5 feet seen), resting on an alternating 
series of grey, earthy, and more or less oolitic limestone and marly 
beds. These strata all vary a good deal in character, the softer 
marly beds becoming indurated into stone at short distances. 
A quarry N.W. of Great Linford Church showed the following 
beds :

These are no doubt portions of the same beds as those seen in the large 
quarry to the west. They are also exposed in a bank further east, and 
in the rail way -cut ting west of Linford station. 
The stone makes a good strong lime for mortar, and a useful lime for 
the land, if put on in small quantities. As a building-material, it is poor, 
although it has been used. 
A pit, and the adjoining railway-cutting at Brad well, near New- 
pert Pagnell, showed the following section :
