tusk. Notwithstanding the care which they exercised under our 
direction in endeavouring to secure the whole or a large portion of 
the tusk intact, the largest fragment we cculd obtain was only 
6in. long, 3in. wide and #in. thick, and although this fragment 
was immersed in hot size it very soon fell into small pieces. Some 
of the figures on Plate 4 are photographs of objects obtained 
here. No. g represents the disintegrated plates of a molar tooth 
of the Mammoth (Zlephas primigenius), Nos. 10 and 11 are 
molars of the great two-horned Woolly Rhinoceros (2. antiquitatis), 
No. 12 a molar of the horse (Zguus caballus), Nos. 13 and 14 were 
too fragmentary for determination, Nos. 15 and 17 are flint im- 
plements. The latter is cut out at the sides of the base to facilitate 
attachment to a shaft, which was probably effected by a bandage 
of raw hide put on when flexible. Such a band if drawn tight and 
beaten down would become quite rigid. No. 16 is an implement 
found on arable land higher up the valley on the western side, 
nearly opposite Keston Church. From the last-mentioned locality 
we also obtained a Neolithic polished implement, 5in. long, 2}in. 
wide at the broad end, and tapering to a point at the other end. 
Nos. 19 and 20 are two small ‘‘ fabricators”? formed out of Lower 
Tertiary pebbles. One of them came from the Hayes pit, and the 
other from Norhead’s Farm, which rises like an island in the 
middle of the valley on the west side of the Westerham Road at 
Biggin Hill, Cudham. 
It now remains to describe, briefly, the courses of the two 
rivers from the foot of Coney Hill. 
The least important of the two came from the direction of 
Farley and Chelsham, and passed through Addington, along what 
is now the road from that village to Hayes. 
The course of the larger river follows the road which passes 
Coney Hill Farm, and runs below West Wickham and Hayes 
Commons towards Keston Church. On the eastern side of that 
road the border of the valley rises steeply, and exhibits old river 
terraces at several points. On the same side, near the foot of Fox 
Hill, there is a disused gravel pit exhibiting large water-worn 
flints. The river here also, as at the Hayes pit, cuts deeply into 
the Thanet sands. Nodules of iron pyrites have been found at 
this pit which were probably brought from the Gault or Lower 
Greensand formation during the planing down of the former 
Wealden heights. The arable land on the western slope is strewn 
with water-worn flints up to an elevation of 4oft. above the road, 
and for a distance of nearly half a mile from it, and here numerous 
palzolithic implements, and the cores from which the flint-flakes 
were struck, have been found. After passing the foot of Fox Hill 
the valley turns towards the west, and after passing through 
Purgatory Bottom it runs southerly, parallel with the Westerham 
Road, to the foot of Westerham Hill, where it branches off into 
several minor terminal valleys.
