Discussion. 



Air. C. Eeid said that in the Cromer Forest bed he had dug up 

 many stumps of trees asserted to have been in situ, and had 

 found them not to be so. He thought that great caution was 

 needed in asserting trees to be in situ. They would usually sink in 

 a vertical position with their roots downwards. Sometimes portions 

 of the soil in which the trees had grown were retained among the 

 roots, and differed entirely from the matrix. 



Eev. H. H. Winwood pointed out that trees often grew in a soil, 

 but the roots did not pierce the underlying clay. Might not this 

 be the case with the Cromer trees mentioned by Air. Eeid ? 



Eev. J. F. Blake spoke of a boring at York with peaty matter in 

 the midst of the Boulder-clays. 



Mr. Tiddeman asked whether it was quite certain that there was 

 Boulder-clay above and below these peaty deposits. 



The Secretary replied that the author stated so distinctly in the 

 paper. 



The President spoke of the importance of comparing together 

 the results of investigations in different areas.
