UPPER EOCENE (bAETON AND UPPER BAGSHOT FORMATIONS). 613 



numerous sections in yellow sands of Upper Bagshot age. We have 

 not found fossils in them, but Prof. Prestwich says fossils occur 

 there. There is a good road-section (33) close to Minley Manor 

 Chapel, and on the opposite side of the outlier there is a very good 

 Upper Bagshot section (34) in a sandpit at the rifle-range. It is 

 about 20 feet deep and shows yellow, irregularly-bedded sand, 

 becoming nearly white at the bottom of the pit. 



Small roadside sections (35) on the side of the Flats just above 

 Eversley Church show the following series of beds : — 



Section 1. Gravel at the top of the Flats. 



Section 2. Yellow sand, with numerous green grains, either 



the bottom of the Upper Bagshot or the top of the 



Bracklesham. 

 Section 3. Green sand (Bracklesham) shown in good section 



some 10 or 15 feet below Section 2. 



At Hazley Heath, to the south-west of Hartford Bridge Flats, is 

 a good brickfield-section in Bracklesham clays ; and above it, at the 

 top of the heath, there is a pebble-bed in loose yellow sands beneath 

 and distinct from the gravel which caps the heath. If this is the 

 Upper Bagshot basement-bed, as it probably is, Hazley Heath is 

 the most westerly point to which we have traced it. 



There are numerous sections in the Upper Bagshot round the 

 Staff College, Sandhurst, and here and there small sections occur on 

 the commons to the north-east. From one (44) we obtained a cast 

 of a bivalve, and from another on Olddean Common a XenopJiora^ 

 another univalve, and a bivalve. 



In the neighbourhood of Wellington CoUege the Upper Bagshot 

 extends further than is shown on the Survey Map, so that Fin- 

 champstead Eidges is not an outlier but a portion of the " main 

 mass " (they are stated to be mapped Upper Bagshot, with some 

 doubt, Mem. Geol. Surv. iv. p. 335). 



At Ambarrow hill there is a small section on the South-Eastern 

 Railway (36), from which we have obtained many fossils, all very 

 badly preserved. Natica, Xenophora, and Voluta are abundant, and 

 we have an impression of Turritella imhricataria and many species 

 which are undeterminable. 



There are small pits in whitish sand at 37, and a deep cutting 

 has recently been made for a road at 38 in yellow sand, also clearly 

 Upper Bagshot. 



The small outlier at Finchampstead Church (39) is also un- 

 doubtedly Upper Bagshot. There are two good sections in cha- 

 racteristic yellow sand at the top of the hill, and the Bracklesham 

 green sand is shown in a road section on the northern slope. 



The greater part of the Wellington-College estate is mapped 

 Bracklesham, but there is a large extent of Upper Bagshot there, 

 and the pebble-bed can be traced over a large area. It is well seen 

 in the following section (40, and fig. 10) : —
