460 h. c. sorby on a coal-measure forest. 



Discussion. 



Mr. Moggridge inquired whether the trees were rooted in solid 

 rock or in earth. Near Swansea trunks of trees were imbedded in 

 solid rock and upright. 



Mr. Grantham inquired whether the trees were broken short off, 

 leaving rugged tops, and whether any trunks were found. 



Prof. Seeley said that in the Eens we find erect stumps of Yew, 

 Oak, and Pine, and that the stumps never rise above the surface of 

 the peat. Sometimes a bed of marine clay overlies the peat, and 

 fragments of the trunks are found scattered in it, showing that the 

 trees stood in the sea and died there. 



Mr. Sorby said that the lower parts of the roots are in soft clay 

 shale, and the upper portions in hard sandstone. He thought that 

 the trees were submerged, and that their trunks decayed down to 

 the level of the water, the surface of the stumps being remarkably 

 level, as though cut off with a saw.
