Resin passages appear to be present in this section, but as 

 decay had evidently taken place before fossilization they are too 

 obscue to permit of accurate description. 



Radial Section (Fig. 1) : In many particulars this section per- 

 mits of the best results, though it is far from being perfectly pre- 

 served. The wood cells are broad. Their length cannot be de- 

 termined. They are provided with one, or in some cases with 

 an interrupted double row, of bordered pits, which are contigu- 

 ous. When they are in a single row the wall is not nearly cov-

 ings. The individual cells appear to be large, and the partitions

Tangential Section (Fig. 2) : The section in this direction is
