DR. E. A. JEWELL ARBER ON THE [April I914, 



VII. The Trapham (Wingham) Boring. 

 (Lat. 51° 16' K, long. 1° 12' E.) 



A boring at Trapham, near Wingham, penetrated 1651 feet of 

 Coal Measures before passing into the Carboniferous Limestone. 

 The whole of the measures of this boring appear to belong to the 

 Middle Coal Measures. The following sixteen species of fossil 

 plants were obtained from this boring, which did not prove to be 

 very prolific of specimens ; nor were these, as a rule, well preserved.

VIII. The Walmestoke Boring. 

 (Lat. 51° 17' N., long. 1° 14' E.) 



A boring put down at Walmestone, north of Wingham, proved 

 1201 feet of Coal Measures, and then passed into the Carboni- 

 ferous Limestone. The flora was found to be large and varied 

 (thirty-three species), considering the comparative shortness of 

 the core.
