in Extra-Tropical Countries. 145 



125 F. in the shade did not shrivel the foliage of this tree; it has also 

 withstood the severest heat in Algeria better than E. globulus; and 

 Dr. Bonavia found it to thrive well in the province of Oude in places, 

 where E. globulus, E. obliqua and E. marginata perished under the 

 extreme vicissitudes of the clime. It does not bear cold so well as 

 E. amygdalina, succumbing when still young at a temperature below 

 23 F., as observed in Italy by Prince Troubetzkoy. In Mauritius 

 and Reunion it resisted the hurricanes better than any other Eucalypt ; 

 in the latter island the Marquis de Chateauvieux observed it to grow 

 65 feet in six years, and it is always of more rapid growth than E. 

 marginata, but less so than E. globulus. It grew also with remark- 

 able rapidity in British Guiana (Jenman). It is recommended as an 

 antiseptic tree for cemeteries in tropical countries. The timber is one 

 of the most highly esteemed in all Australia among that of Eucalypts, 

 being heavy, hard, strong and extremely durable, either above or under 

 ground, or in water. For these reasons it is very much prized for fence- 

 posts, piles and railway-sleepers. For the latter purpose it will last 

 at least a dozen years, but if well selected much longer. It is also ex- 

 tensively employed by ship-builders for main-stem, stern-post, inner- 

 post, dead-wood, floor-timbers, futtocks, transoms, knighthead, hawse- 

 pieces, cant-, stern-, quarter- and fashion-timbers, bottom-planks, breast- 

 hooks and riders, windlass and bow-rails. It should be steamed before 

 it is worked for planking. Also largely used for felloes, buffers and 

 posts and any parts of structures, which come in contact with the 

 ground; not surpassed in endurance for woodbricks in street paving 

 and for tramways. Next to the Jarrah from West Australia this is 

 the best Eucalyptus-wood. for resisting the attacks of the crustaceous 

 chelura and limnoria, the teredo-mollusk and white ants, and it has 

 the advantage of being considerably stronger, proving equal in this 

 respect to American white oak. According to my experiments and 

 those of Mr. Luehmann, it is surpassed in resistance to transverse 

 strain by E. melliodora, E. polyanthema, and particularly E. sidero- 

 phloia and E. Leucoxylon, though stronger than the wood of many 

 other of its congeners. The kino of E. rostratais far less soluble in 

 cold water than that of E. calophylla, and is used as an important 

 medicinal astringent. For other details of the uses of this and some 

 Eucalyptus -trees, refer to the Reports of the Victorian Exhibitions of 

 1862 and 1867, also to the ten Decades of the Eucalyptographia. 

 E. rostrata becomes already as spontaneous disseminated in Southern 

 France, according to Prof. Ch. Naudin, whose important " Memoire 

 sur les Eucalyptus 1883," should also be consulted regarding the 

 characteristics, development, hardiness and uses of Eucalyptus. 



Eucalyptus salmonophloia, F. v. Mueller. 



The Salmon-barked Gumtree of South-Western Australia, attaining 

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

 is available for profitable oil-distillation. The shining mixed whitish 

 and purplish bark does not give off a white coloration like that of E. 

 redunca.
