broke after a flection of 17 inches under a pressure of 49 tons. 

 It combines with the ordinary qualities of many Eucalypts the 

 advantage of yielding from its leaves a rather large supply of 

 volatile oil of excellent lemon-like fragrance, in which respect 

 it has, among about 150 species of Eucalypts, only one rival. 



Eacalyptos coriacea, A. Cunningham. {E. jaanoiflora, Sieber). 



New South Wales, Victoria, Tasmania. A tree of handsome 

 appearance, with a smooth, white bark, and generally drooping 

 foliage, attaining considerable dimensions ; vernacularly known 

 as a White Gum or Drooping Gum or Swamp Gum-Tree. It 

 grows best in moist gol^nd, ascends to an elevation of 5,000 feet, 

 and is one of the hardiest of all its congeners. Its timber is 

 used for ordinary building and fencing pm-poses. 



Eucalyptus cornnta, Labillardiere. 



The Yate Tree of South- West Australia. A large tree of rapid 

 growth, preferring a somewhat humid soU. The wood is used 

 for various artizans' work, and there preferred for the strongest 

 shafts and frames of carts and other work requiring hardness, 

 toughness, and elasticity, and is considered equal to the best 

 Ash Wood. The tree appejirs to be well adapted for tropical 

 countries, for Dr. Bonavia reports that it attained a height 

 of 8 to 10 feet in the first year of its growth at Lucknow, and 

 that the plants did not sufEer in the rainy season like many other 

 Eucalypts. The dry wood sinks in water. 



Eucalyptus corymbosa, Smith. 



The Bloodwood Tree of New South Wales and Queensland. A 

 tree attaining large dimensions ; it has a rough furrowed bark 

 and a dark-red wood, soft when green, but very hard when

 for fence-posts, rails, railway sleepers, etc. (Hartmann). The 

 bark is rich in kino. 



Eucalyptus crebra, F. v. Mueller. 



The Narrow-leaved Iron-Bark Tree of New South Wales and

 sleepers, also for wagons, piles, fencing, etc. E. melanophloia, 

 F. V. M., the Silver-leaved Iron-Bark Tree, and E. leptophleba 

 and E. drepanophyUa, are closely allied species of similar value. 

 They all exude astringent gum resin in considerable quantity, 

 resembling kino in appearance and property. 



Eucalyptus diversicolor, F. v. Mueller. {E. colossea, F. v. M.) 

 The Karri of South- West Australia. A colossal tree, excep-
