FLOWEB, DISCOVERIES OF FLINT IMPLEMElirTS. 449 



further has transpired. It is not impossible that the bed a may, in- 

 stead of underlying, be bedded vertically against No. 5, and that 

 the shaft, after passing through No. 5, encountered a lateral protru- 

 sion of a. If so, there would be no reason for regarding a as any- 

 thing else than the bed No. 6, which it resembles in parts distant 

 from Norwich.

 [Plate XX.] 



In June 1866 I had the honour to lay before the Society a paper 

 upon some flint implements then lately found at Thetford in the 

 valley of the Little Ouse river f ; I have lately occupied myself 

 with further investigations of the same district, the results of which, 

 are, I trust, of sufficient interest to justify me in bringing them to 

 the notice of the Society. 



The localities whi(^h I have now examined are four in number. 

 In each of these flint implements have been found, and in several of 

 them in great abundance, corresponding in the main, as well in 

 fashion as in material, with those of St. Acheul, Thetford, Salisbury, 

 and Icklingham, which are now so well known. 



Broomhill. — The flrst deposit which I have to notice is found at 

 Broomhill, on the north bank of the river, about five miles from 

 Thetford, and two from Santon Downham mentioned in my former 

 paper. The implements, which are usually much rolled and worn, 

 and are often stained to a chocolate-colour, are here found in a 

 gravel-pit about 350 feet from the river-bank. They are usually 

 met with in a bed of ferruginous flint- gravel about 2 feet thick, 

 resting immediately on the surface of the chalk, and 5 or 6 feet 

 above the level of the river. This gravel, which is very coarse and 

 not much rolled, contains large flint nodules, some of them weighing 

 over a hundredweight, and is mixed vsdth rounded quartzite 

 pebbles and roUed fragments of chalk. It is overlain by another 

 stratum of gravel, less ferruginous and containing a greater propor- 

 tion of broken chalk ; and this bed, in its turn, is capped by a mass 

 of siliceous sand, sparingly intermixed with angular flints of no great 

 dimensions. These several beds constitute a mass of from 25 to 30 

 feet in thickness. No gravel is found on the opposite bank ; the 

 ground there, which is moor or fen, rises very slightly above the river- 

 surface, and forms a plain extending about half a mile to the base of 

 the chalk-hills. 



Gravel Hill, Brandon. — At this place, situate two miles and a 

 half west of Broomhill and on the Suffolk side of the river, another
