obtained from this tree in very poor soil is perhaps larger than 

 that of any other kind, and thus this species can be included 

 even in its native country, where it is naturally common and 

 easily re-disseminated, among the trees for new forest plantations 

 in barren woodless tracts, to yield readily and early a supply of 

 cheap and easily fissile wood. The young trees are sometimes 

 used for telegraph poles. The fresh bark contains from 11 to 

 ] 3| per cent, kino tannic acid. 



Eucalyptus oleosa, F. v. Mueller. 



One of the smaller Eucalypts known as Mallee, extending 

 from East to West Australia through the desert regions. 

 The essential oil, in which the foliage of this species is very 

 rich, dissolves, according to Mr. Bosisto, India-rubber without 

 heat. It is also one of the best to dissolve amber and other 

 fossil resins. The variety hngirostris attains a height of 

 120 feet, with stems of 70 feet without a branch, in West 

 Australia, where it is vernacularly known as MorreU. The 

 wood is remarkably hard, splits freely, and is used for spears, 

 rafters, fence-rails, wheelwrights' work, agricultural imple- 

 ments, etc. It is of a red tinge and sinks in water, also when 

 dry. 



Eucalyptus paniculata, Smith. 



The White Iron-Bark Tree of New South Wales. This species 

 furnishes a hard, durable wood, excellent for railway sleepers, 

 according to the Rev. Dr. Woolls. It is also much used for 

 building and fencing, as it splits well and is lasting under- 

 ground. All the trees of this series are deserving of cultiva- 

 tion, as their wood, though always excellent, is far from 

 alike, and that of each species preferred for special purposes 

 of the artizan. 



Eucalyptus phoBuicea, F. v. Mueller. 



Carpentaria and Arnhem's Land. Of the quality of the 

 timber hardly anything is known, but the brilliancy of its 

 scarlet flowers recommends this species to a place in any 

 forest or garden plantation. For the same reason also 

 E. miniata from North Australia, and E. ficifolia from 

 South- West Australia, should be brought extensively under 

 cultivation. . 



Eucalyptus pilularis, Smith. 



The Black Butt Tree of South Queensland, New South Wales, 

 and Gippsland. One of the best timber-yielding trees about
