with a reddish sand, and deposited on an irregular surface 

 of the I.ias clay. Some of the blocks are as large as the 

 hand can grasp, or bigger : one quartz Ijlock measured 

 5 in. by 4^/^ in. Many of the blocks are very rounded, 

 others of all kinds arc sub-angular. The Jurassic blocks 

 arc sub-angular. The flints are very little water-worn. 



The great difficulty is to account for the presence of 

 the flints. H. J. Osborne White wrote to me — " The 

 " presence of flints at Moreton [in-thc-Marsh] and other 

 " places still more remote from any existing occurrence of 

 " the Upper Chalk is very hard to explain satisfactorily on 

 " any theory with which I am acquainted."* 



The subject is one of much interest ; but I wish to 

 examine more of these exposures — for instance, those 

 near Moreton — before I say much. 



[In connection with the subject it may be mentioned 

 that in a deposit of river gravel near Frampton-on-Severn, 

 mostly composed of local materials, I found a lump of 

 chalk. Writing from recollection and from where Mr. 

 Lucy's paperf is not available, I think that this agrees 

 with his experience. But whence came this chalk, and 

 how ?] 



While in the neighbourhood of Evesham and the Avon, 

 I may remark on the possibility of travelling from the 

 Avon valley at this point into the Thames basin, and yet 

 be in a valley all the time. From Evesham, the route is 

 up the valley of the Isborne, past Winchcombe, to 

 Charlton Abbots. Then there is a rise to higher ground, 

 but it is only low ground in comparison with the sur- 

 rounding hills. It is, however, the watershed of the 

 Severn and Thames river-systems. And the valley of the 

 Coin is entered just by Charlton Abbots.
