280 THOUGHTS IN A GKAVEL-PIT. [xi.

 ward even down into Kent, and stretched also over 

 Winchfield and Dogmersfield hither. 



What broke them up ? What furrowed out their

 sketch for you shortly. 



A great continent to the south England, probably 

 an island at the beginning of the period, united to the 

 continent by new beds the Mammoth ranging up to
