" The stump was found to originate in a six-inch coaly seam, thirty- 

 five feet five inches below that worked in the Cumberland Mine in coal- 

 group 29a of Dr. Dawson's section, or division 4, section xi. of Sir 

 W. E. Logan's section*, and separated by an underclay of 3 feet 

 <± inches from the underlying seam of coarse coal in group 30. The 

 downward termination of the tree exhibited spreading roots, which 

 were, however, in a friable condition and not well preserved, but 

 exhibited on the surface, inside the coaly bark, a fine transverse 

 striation, scarcely visible to the naked eye. The surface-markings 

 of the trunk are also indistinct ; but it shows a coarse longitudinal 

 striation and indications of broad flat ribs. The accompanying 

 drawings (figs. 1 and 2) will illustrate the mode of occurrence of the 

 tree in the cliff, and also the principal dimensions of the trunk and 

 axis, with the position of the latter in the cast." 



The axis of this remarkable stem is about six centimetres in its
