120 SELECT PLANTS FOR INDUSTRIAL CULTURE 



200 feet, and furnishing a very durable, tough wood, used for 

 building and other purposes. The young stems serve as 

 wagon poles. Dr. Aberg found this to be one of the fastest- 

 growing Eucalypts at Buenos Ayres. 



Eucalyptus tereticornis, Smith.* 



From East Queensland, where it is termed Red Gum-Tree, to 

 Gippsland, attaining a height of 160 feet. Closely allied to 

 E. rostrata. The timber is esteemed for the naves and felloes 

 of wheels. For telegraph poles and railway sleepers it is in- 

 ferior to some of the Iron Bark trees, lasting a shorter time, 

 and then not rarely decaying by dry rot. Quite under ground, 

 it remains sound much longer (Thozet), but much depends, as 

 regards its durability, on the locality where it is obtained and 

 the manner of drying. 



Eucalyptus terminalis, F. v. Mueller. 



The Blood wood Tree of North Queensland, closely allied to E. 

 corymbosa, attaining a considerable size. The wood is dark 

 red, hard, and extremely tough. Particularly adapted for 

 tropical climes. 



Eucalyptus tesselaris, F. v. Mueller. 



North Australia and Queensland. Furnishes a brown, rather 

 elastic wood, not very hard, easily worked, of great strength 

 and durability, available for many kinds of artizans' work, and 

 particularly sought for staves and flooring. The tree exudes 

 much astringent gum-resin (P. O'Shanesy). Many other 

 Eucalypts could have been mentioned as desirable for wood 

 culture, but it would have extended this enumeration beyond 

 the limits assigned to it. Moreover, the quality of many 

 kinds is not yet sufficiently ascertained, or not yet fully 

 appreciated, even by the artizans and woodmen. All the 

 Eucalypts are valuable for the production of tar, pitch, acetic 

 acid, potash, and various dye substances. 



Eucalyptus viminalis, Labillardiere. 



South-East Australia. On poor soil only a moderate- sized 

 tree, with a dark rough bark on the trunk, and generally known 

 as Manna Gum-Tree ; in rich soil of the mountain forest it 

 attains, however, gigantic dimensions, rising to a heignt of 

 more than 300 feet, with a stem up to 15 feet in diameter. 

 It has there a cream-coloured, smooth bark, and is locally known 

 as White Gum-Tree. The timber is light-coloured, clear, and 

 though not so strong and durable as that of many other
