Abbeville, tlie rising 
ground on the south- 
east side of the town 
on which is situated 
the Champ de Mars, the 
Moulin -Quignon, and 
the suburb of St. Grilles, 
and Mautort on the 
west. 
" There are two pits 
at Mautort where flint 
implements have been 
found, one a shallow 
one, no longer worked, 
in the valley near the 
church, and another one 
on the side of the hill 
on the' road leading to 
Moyenville, and at a 
height probably about 
equal to that of Moulin 
Quignon, or about 90 
feet above the valley. 
The section, which was 
badly exposed on the 
two occasions when I 
was there, consists pro- 
bably of — 1. Brown 
sandy clay and a few 
angular fragments of 
flint, 6 feet. 2. Sub- 
angular ochreous and 
ferruginous flint-gravel, 
4 feet. 3. White and 
yellow sand, irregular, 
3 feet. 4. Coarse light 
sandy, chalky, and marly 
flint-gravel ; no bones : 
flint implements said 
to be met with at a 
depth of six to eight 
feet ; reposing upon an 
irregular surface of 
chalk, 12 ? feet. The 
flint implements here 
are remarkable for their 
bright white colour. 
The bed of gravel ceases 
at this elevation, but 
the hni rises to a height 
of two hundred and 
fifty-two feet, showing 
chalk with a slight cover 
ing of red clay and flints.
