CuAP. III. BROUGHT UP BY WORMS. M3 



A field, whicli adjoins the one just de- 

 scribed, slopes in one part rather steeply 

 (viz., at from 10° to 15°); this part was last 

 ploughed in 1841, was then harrowed and 

 left to become pasture-land. For several 

 years it was clothed with an extremely scant 

 vegetation, and was so thickly covered with 

 small and large flints (some of them half as

 When they ran down the slope the stones

 whether I should live to see these larger flints 

 covered with vegetable mould and turf. But 

 the smaller stones disappeared before many 

 years had elapsed, as did every one of tlie 

 larger ones after a time ; so that after thirty 

 years (1871) a horse could gallop over the

 were not frequent for several years, yet some 

 were thrown up month after month, and
