The Predville Series is also a shale-series, but the shales are more 

 sandy than at Waldershare. 



The present paper contains an account of the fossil plants 

 collected as the result of a thorough examination of the Walder- 

 share and Predville cores. I do not propose to discuss here the 

 general questions relating to the geology of the Kent Coalfield, nor 

 to include a detailed account of the beds proved by these borings. 

 These matters have been already dealt with in some detail by 

 Prof. Boyd Dawkins, 1 who had the geological oversight of the borings. 

 In 1907, I was invited by the Kent Coal Concessions, Limited, to 

 undertake the collection and examination of the plant-remains, 

 in order to ascertain if possible the palseobotanical horizons of the 

 two series. This I have been able to do, as will be seen here. I 

 may take this opportunity to acknowledge the facilities and valuable 

 information placed at my disposal for this purpose by Mr. Arthur 

 Burr, Managing Director of the Company, and by Mr. Malcolm 

 Burr, F.Gr.S., the Resident Engineer of the workings, and I would 

 also express my thanks for the invariable kindness and courtesy 

 which I have received at their hands. 



The literature of the fossil flora of the Kent Coalfield is naturally 

 scanty. Prof. Boyd Dawkins 2 states that, in 1892, in a report by 

 Mr. McMurtrie, the conclusion was expressed that the Dover Series 

 belongs to the same horizon as the Badstock and Parrington Series 

 of the Somerset Coalfield. I have not, however, seen this report.
