In the main this must be regarded as belonging 

 to the Glacial Drift, although it may have been 

 rearranged in places by the stream. 



Further south, and to the east of Charwelton, 

 the Upper Lias clay with Ammonites fihulatns 

 is seen in the cutting faulted against the 

 Marlstone, the newer formation occupying (as 

 before mentioned) the trough, and rubble from 

 the Middle Lias being washed over the clay- 

 slope of the Upper Lias. 



South of the river Cherwell, and to the 

 north-east of Charwelton Lodge, there are 

 shallow cuttings in stiff grey and yellow clay 

 (Upper Lias), with a little gravel south of 

 Blindpool Spinney ; and near by there are 

 ferruginous, sandy beds, a downwash on to 

 the clay from the " Northampton Sands " of 

 Hinton Hill. The sections here were much 

 obscured at the time of my visit, but my 

 observations accord with those of Mr. Beeby 

 Thompson, who discovered estuarine sands 

 with plant-markings, and attributed the 

 position of the deposit to slips from the higher 

 grounds of Hinton Hill.^ 



To the north of Woodford Halse, a cutting 

 about 15 feet deep showed Upper Lias clay 

 dipping gently towards the south. It contained 

 two bands of ferruginous, earthy limestone, 

 which became thinner towards their outcrop 

 on the north. Ammonites communis, A. bifrons, 

 and A. serpentinus (falcifer) oGcur here. 

 Crossing the East and West Junction Eailway 

 to the south of Woodford Halse, we come to 

 a cutting which showed Chalky Boulder-clay 

 (3 or 4 feet) resting on an irregular bed of 

 sand and loam, beneath which was a mass of 

 stiff blue clay, with layers of fine chalk stones 

 — the clay, no doubt, largely derived locally 

 from the Upper Lias. This was the first mass 

 of Glacial Drift encountered along the railway 

 south of Willoughby, if we except the gravel 

 before mentioned. 



Further south, to the north-east of Eydon, 

 fine gravel and gravelly loam were seen, resting 

 on blue clay (Upper Lias). By Foxhall Farm, 

 west of Moreton Pinkney, red sand was ex- 

 posed, and a little further south there was 

 an excavation showing ten feet or more of 

 coarse gravel and sand, with one foot of stony
