externally in crumbling, irregular scales, fuL of readily visible 

 but small hard, white bodies. 



Uses, etc. "Like Ash and used for the same purposes, . . . 

 not plentiful " (24).

Colour. Heart-wood dirty brown, streaky : well denned from 

 the sap-wood, which is about 3 inches wide and marked with

Anatomical Characters. As those of O. Cunninghami (No. 

 138), with the following variations : 



Pores. Prominent : 10-50 per sq. mm. 



Ring-boundaries. Very clear, fine white lines, and rather pro- 

 minent in the sap-wood.

Physical Characters, etc. Recorded dry-weight 32|-63| Ibs. 

 per cu. ft. Hardness Grade 5, compare English Elm. Smell 

 none when dry. " Like beet-root " (87). Burns well and 

 quietly : embers glow in still air : heat expels an orange or red 

 juice. Solution pale yellow.
