Eucalyptus saligria, Smith. 



Eastern extra-tropic Australia. Stems clear up to 100 feet occur 

 with basal girth of 26 feet. The wood, employed for rails, will last 

 a life-time. Hardier than E. globulus [A. R. Crawford]. Accord- 

 ing to the Rev. Dr. Woolls the wood is of excellent quality, and 

 largely used for building purposes. The tree is generally found on 

 rich soil along river-banks. 



Eucalyptus salmonophloia, F. v. Mueller. 



The Salmon-barked Grumtree of South-Western Australia, attain- 

 ing a height of 120 feet. The timber is good for fencing, while 

 the foliage is available for profitable oil-distillation. The shining 

 mixedly whitish and purplish bark does not give off a white color- 

 ation like that of E. redunca. 



Eucalyptus salubris, F. v. Mueller. 



The Grimletwood or Fluted Gumtree of Western and Central 

 Austalia, living on poor dry soil and in the hottest desert-clime. 

 It is generally a slender-stemmed tree, sometimes to 100 feet high 

 and to 2 feet in stem-diameter, with scanty foliage. The bark is 

 shining with a brownish tinge, and has broad longitudinal and 

 often twisted impressions, or roundish blunt longitudinal ridges. 

 The wood is hard and tough, but worked with comparative ease, 

 heavier than w r ater, even when dry. It serves locally for roof- 

 supports, fence-posts and rails, poles and shafts. For xylo- 

 graphy it seems better than Pear-tree wood, and deserves attention 

 for this purpose. The tree exudes kino. 



Eucalyptus siderophloia. Bentbam.* 



The Large-leaved or White or Grey Ironbark-tree of New South 

 Wales and South- Queensland, attaining a height of 150 feet. 

 According to the Rev. Dr. Woolls this furnishes one of the strongest 

 and most durable timbers of New South Wales ; with great advant- 

 age used for railway-sleepers, jetty-piles and for many building 

 purposes. It is likewise highly appreciated by wheelwrights, 

 especially for spokes, also well adapted for tool-handles and various 

 implements. Found by us to be even stronger than hickory, and 

 only rivalled by E. Leucoxylon. It is still harder than the wood 

 of E. Leucoxylon, but for this reason worked with more difficulty. 

 Well seasoned it is slightly heavier than water. The Melbourne 

 price of the timber is about 2s. 6d. per cubic foot in the log. The 

 tree yields much kino. Mr. Newbery obtained from the bark 8 to 

 10 per cent, tannin. This species is often confounded with E. 

 resinifera in culture.
