X. The Maydexsole Boeing. 

 (Lat. 51° 10' N., long. 1° 18' E.) 



A boring at Maydensole Farm, near West Langdon, penetrated 

 to a depth of 2565 feet in the Coal Measures, without proving the 

 entire thickness of the measures as there developed. The higher 

 portion of the beds passed through (about 1156 feet) appears to 

 belong to the Transition Coal Measures. The lower beds, about 

 1409 feet, are attributed to the Middle Coal Measures. The floras 

 of both horizons are comparatively poor, fifteen species being 

 identified from the higher and ten from the lower horizon.
