464 ME. E. M. DEELEY ON THE PLEISTOCENE 



Similar sections may be seen at Kilworth, Smeeton, Saddington, 

 Shearsby, Bruntingthorpe, Husbands Bosworth, Sibbertoft, &c., &c. 

 At Sibbertoft it is consolidated into stony masses five feet in thickness. 

 By far the finest section is, or was, to be seen in the railway ballast- 

 pits at Kilworth, a few miles south of the Trent basin. The section 

 was several hundred yards long and about thirty-five feet deep. 

 The gravel was generally stratified in beds of varying degrees of 

 coarseness and contained numerous false-bedded layers of sand and 

 seams of loam or clay. In the greater number of instances the 

 -oblique bedding pointed to currents from the east or north-east. The 

 pebbles were mostly well rounded. Here and there an angular 

 boulder occurred, stuck on end, as though it had been dropped there, 

 •or the gravel lost all traces of bedding and presented a mere 

 jumbled mass of stones and sand. Cretaceous and Jurassic debris 

 were most plentiful, but Coal-measure sandstone, black and white 

 Mountain Limestone, grey granite, and other rocks were to be seen. 

 One mass of granite measured 2' x 2' x 1''5 ; a boulder of Carbo- 

 niferous Limestone I'xl'xl', and one of gritstone 2'xl'xl'. 

 Quartz and quartzite pebbles were scarce. 



To what extent the Chalky Gravel is spread over the northern 

 portion of Warwickshire, I have been unable to ascertain. 



In the Ashby-de-la-Zouch coal-field it is tolerably well developed. 



South of Haven stone a good section, about 10 feet deep, exposes 

 stratified fiinty gravel. 



In the neighbourhood of Market Bosworth the high plateau to the 

 east and south is covered by gravel resting conformably upon silty 

 Chalky Clay almost free from pebbles. There are several sections — 

 one just north of Market Bosworth, another about one mile south 

 of Cadeby, a third north of Shenton, and a fourth south, of Sutton 

 Pields. On the hills south of Sutton Fields there is about twenty 

 feet of typical Chalky Gravel. The deposit is light in tint, false- 

 bedded, and contains flints in the pebbly beds. 



On the south-easterly spurs of the Pennine Chain the Chalky 

 Gravel is not extensively developed, but it becomes more plentiful 

 in a westerly direction. In jS"ottinghamshire flinty gravel may be 

 seen near Blidworth, and at other points, resting upon the sandstone. 



South of J^ottingham, on Wilford Hill, there is about 20 feet of 

 gravel and sand, but no sections are shown. 



In Derby (fig. 1) a patch of stratified gravel with fiints is exposed 

 by an excavation in Green Lane. This deposit and another near the 

 Arboretum very probably belong to the Chalky-Gravel stage. 



On Chellaston Hill (fig. 1) the Chalky Boulder-clay is capped 

 by gravel reaching a thickness of at least 17 feet, and covering an 

 area of about a quarter of a square mile. A section may be seen 

 on the west side of the stile-road leading from Chellaston to Weston. 

 The sand is clean, stratified, yellow or reddish brown in colour, and 

 contains fiints and quartz pebbles. The section fig. 3 (p. 460) passes 

 through this deposit. 



South of Ashbourne, on the high land, gravel is of tolerably frequent 

 occurrence. In most cases the deposit is very much disturbed, signs
