plentiful and not much used " (24). " Timber up to 70 ft. long 

 by 3-6 ft. in diameter. Celebrated for its strength and dura- 

 bility, . . . large engraving blocks, does not wear and bears

 piers, . . . resists the teredo, . . . railway carriage building, 

 bearings, ships' blocks and every purpose where great strength 

 is required " (91). " Mill and wheelwork " (60).

Anatomical Characters. Transverse section : — 



Pores. Visible, size 4, uniform : irregularly distributed in 

 long tree-like, radially-straggling strings with poreless intervals : 

 few, 0-20 per mm. 



Rays. Need lens, very fine, size 5-6, uniform : equidistant : 

 many, 12-15 per mm. : straight, not avoiding the pores : white. 



Rings. Just visible : boundary a fine, white, gently undu- 

 lating line, usually interrupting the strings of pores. 



Soft-tissue. Abundant, imbedding and compacting the 

 strings of pores : white : perhaps also the boundary-line. 



Pith. ? 



Radial Section. Pores, fine scratches, need lens. Rings, 

 clearly visible, finely-cut lines. Soft- tissue, just visible, fine, 

 white streaks. This probably gives the colour to the streaks in 

 the sap-wood, where it is, however, pink. 



Tangential Section. As the Radial, but the rays are minute lines 

 about 0*2 mm. high, which require the microscope.
