MYALL 



Physical Characters, etc. Recorded dry-weight 76 Ibs. 1 per 

 cu. ft. Hardness Grade i, compare Ebony. Smell fragrant like 

 violets, more so when worked. Taste nauseous. Burns in- 

 differently well : heat expels a juice along with puffs of vapour : 

 embers glow brightly in still air. Solution, dirty brown. 



Grain. Rather fine, slightly sinuous, even, dense. Surface 

 bright. Resin exudes after a time and hardens in globules. 



Bark. ? 



Uses, etc. " Much prized by cabinet makers and turners " 

 (5). A good turners' wood and for such purposes where hardness 

 is required: ornamental. " Tobacco pipes, stock whip-handles, 

 and by the aborigines for boomerangs " (85).

Colour. Very dark brown with light coloured lines, few, if 

 any, black bands. Sap-wood. ? 



Anatomical Characters. Transverse section : 



Pores. Very prominent from their colour and size, Grade 

 3 to 4, uniform except within the groups : evenly scattered, 

 perhaps a tendency to wavy lines : groups rarely joined to others : 

 many single or in pairs and threes and fours : contents not readily 

 seen in the solid, but glisten after moistening : 10-25 P 61 " s q- nim. 



Rays. Need lens, size 5 to 6, uniform : equidistant, a pore- 

 width apart, sometimes penetrating the soft-tissue around 

 the pores : many 8-n per mm. 



Rings. Doubtful, but clear with lens. Boundary a fine white 

 line at intervals, strongly suggesting the boundary : independent 

 of the pores : contour irregular. 



Soft-tissue. Abundant in broad, brown borders to the pore- 

 groups, but not connecting them except in crowded rings : 

 perhaps also the ring-boundary (see above). 



Pith. ? 



Radial Section. Pores, prominent as light brown lines from 

 which the gum often exudes and stains the wood. Rays, very 

 minute, rather darker flakes. Colour bands rare, if any. Soft- 

 tissue clear as borders to the pores. 



Tangential Section. As the Radial, but the rays are very 

 minute, dark lines, blunt rather than spindle-shaped, about 

 o'2 mm. high.
