ANATOMICAL CHARACTERS. 



Transverse Section. Darker than the other sections. 



Pores. Visible to the unaided eye when moistened; uniform; 

 not diminishing towards the close of the season's growth; little 

 variation except in the groups. Evenly distributed; single, also 

 radial sub-divided groups of 2-4 Pores, having a tendency to join 

 up to longer strings. Contents often sparkling brightly, giving the 

 section a frosted appearance. 



Rays, Visible with the lens, very fine; uniform; regular; less 

 than the width of a Pore apart; hoary, weak threads widely avoid- 

 ing the Pores. 



Rings not defined ; boundary doubtful, the zones of rather 

 denser wood may indicate the close of the season's growth; contour 

 regular. 



Soft Tissue in very narrow borders or sheaths to the Pores. 



Pith.( ?) 



Radial Section. Similar in shade to the Tangential Section. 

 The Pores are medium-sized scratches. The Rays are minute, 

 inconspicuous, semi-transparent flakes. The rings are not indi- 

 cated. The Soft Tissue sometimes appears as sufficiently pro- 

 minent borders to the Pores to give the section a hoary appearance. 



Tangential Section as the Radial, but the Rays need the lens, 

 being minute and about 1 m/m. high, and consist of unusually large 

 cells.
