Descrix^tion of the v/ood 



Sapwocd thick, nearly white; heartv/oca much dar^ier. 

 ,7ood very hard, heavy, strong, tough, cross and fine-grained, 

 difficult to vi/ork, taking a good polish, durable in contact 

 with the soil. .Annual rings of growth not visible under 

 high power microscope. 



Pores (transverse section) nu-ierous, small (.12 mm. 

 in diameter), round, open in sapwood, closed with light 

 brovm tyloses in heartwood, and arranged singly or in 

 pairs regularly throughout the v/ood. Vessel walls (lon- 

 gitudinal section) with numerous rather large bordered pits. 

 Perforations simple, ./ood fibers about 1.4 mm. long, v/ith 

 thick walls and small lumina ; j^its very small and simple. 

 <7ood parenchyma abundant, arranged chiefly around vessels 

 and in short taiigential lines (transverse section). Hays 

 storied, numerous, very narrow and barely visible under 

 hand lens on smooth ti-ansverse section, from 1 to 2 cells 

 wide and from a few to 10 or 12 cells high.
