FLOWER — DISCOVERIES OP ELINT IMPLEMENTS. 451 



doubtless at one time continuous. There is not so much, quartzite 

 and jasper here, nor is the gravel so ferruginous as at Brandon; 

 and being worked for the parish roads, and not for sale, as in the 

 other pits, fewer flint implements have been obtained from it. The 

 gravel extends over an area of about 60 acres, and lies immediately 

 upon the chalk, to the same depth as at Brandon — 8 to 10 feet. 



Shrub Hill, Feltiuell. — This deposit differs materially from the 

 others ; it is found on a farm known as Shrub Hill farm, situate in 

 the fen on the Norfolk side of the river, and about eight miles below 

 Gravel Hill. The implements occur in, or rather beneath, a patch of 

 coarse flint-gravel and sand, which is apparently completely isolated. 

 The chalk is here wanting, and the gravel, which is spread over an 

 area of more than twenty acres, reposes immediately upon the sur- 

 face of the gault. This bed, which is now extensively worked, was 

 until lately quite unknown, the gault and the gravel being alike 

 effectually concealed by the great bed of peat which just covers 

 them. Although not laid down in any map, this gault is evidently a 

 continuation of the bed, portions of which are shown in the Society's 

 map, at Downham, Cambridgeshire, to the south, and Stoke Perry, 

 Norfolk, to the north. 



The gravel here is about 12 feet in thickness, but at the surface 

 it is only 6 feet above the river. The implements here, as at 

 the several other places above described, are, with very few excep- 

 tions, found at the bottom of the gravel, and not seldom they are 

 lying upon the surface of the gault ; they are usually much worn 

 and rolled, and occur in considerable numbers : the gravel here is 

 unstratified, and contains much less quartzite than at Brandon, and 

 the overlying sands do not attain to so great a thickness. 



Both at Broomhill and Brandon, as well as at Shrub, the imple- 

 ments are found in considerable quantities ; I have procured several 

 hundred specimens, sometimes as many as a hundred at a time. 

 Other collectors have also visited the pits, and I have no doubt 

 that there have been at least 1500 specimens procured from them 

 within the last two years. When it is considered how many must 

 escape the notice of the workmen, we may well beheve that 

 the valley of the Little Ouse is as prolific of these objects as that of 

 the Somme, if not more so. 



It has been usual hitherto to consider them as divisible into three 

 kinds, — the flakes, the pointed, and the ovoid; but several others may, 

 I think, now be distinguished. One implement, from Shrub Hill, which 

 was found on the surface of the gault, is probably the largest yet 

 discovered in England or France ; it is 11| ins. long, and its cir- 

 cumference at the thickest part is 13 inches. Two of those pro- 

 cured from Brandon are formed from quartzite-pebbles similar to 

 those among which they are imbedded. Mr. John Evans has 

 also found one of the same material, although of a somewhat dif- 

 ferent form, and he has obtained a well-shaped implement of diorite 

 from the same place ; in each of these a portion of the original sur- 

 face remains. These, I believe, are the only instances in which such
