PARTICULARLY OF THE VALLEY OF THE GIPPING.

The boggy meadows in this part have generally a narrower breadth than before, and are 

 bordered by mounds which display a gravelly sandy soil, commonly called light land, but very 

 often the drift-clay is shewn by drains and ditches to come down to the bottom on both sides ; 

 the before-mentioned gravel, &c. only lie against it. 



Just before the railway enters Stow market it cuts through a spur which comes down from 

 the Stowupland platform, giving a good section 60 or 70 feet high of pure blue clay-drift, 

 resting upon a compact mass of sand ; the sand is of a ferruginous red colour at the top but 

 white below, and I found in it one or two small pieces of shells resembling worn bits of 

 ostrea. The line of junction of the clay and sand, as far as it can be traced, is very irregular; 

 and at both extremities of the cutting the sand apparently gets confused with a mass of 

 singularly rough gravel full of boulders of all sizes, which is also overlaid by the blue clay : 

 the opposite side of the cutting is of small altitude, and is composed entirely of this irregular 

 rubble. 



On the same side the ground at the back of Thorney Hall, which rises rapidly, is faced 

 with sand, though both the roads ascending it cut deep enough to expose the concealed drift- 

 clay. 



The town of Stowmarket covers the opposite side at this point, and almost reaches up 

 to the level where the subsoil is unmistakeable drift-clay : a brickyard however intervenes, 

 occupying an ascending hollow, but only shews two layers distinctly stratified of a greyish 

 brick-clay differing from each other in tint ; this is evidently reconstructed drift. The work- 

 men spoke of some kind of organic remains being found here, but had none to shew me. 



A few years ago an artesian well was sunk at a brewery in the middle of the town, and 

 the following fig. (13) has been given me as its section : ,
