vessels of this and perhaps all other Eucalypts can be used for the 

 same purpose. The stem of this tree may occasionally be observed to 

 10 feet in diameter; it is the only tree in West- Australia which yields 

 copiously the fluid and indurating Eucalyptus-kino; this is soluble in 

 cold water to the extent of 70 to 80 per cent. This species will only 

 endure a slight frost; its. flowers are much frequented by the honey- 

 bee. 



Eucalyptus capitellata, Smith. 



One of the Stringybark-trees of South-East-Australia, extending 

 into the dry mallee-country, attaining occasionally a height of 200 

 feet. The timber is principally used for fence-rails, shingles and 

 rough building purposes. This species might with advantage be 

 raised on wet sandy land. 



Eucalyptus citriodora, Hooker. 



Queensland. A handsome slender tree with a smooth white bark, 

 supplying a useful timber. Succeeded remarkably well at Lucknow 

 (Ridley), also at Zanzibar, where it grows at a tremendous rate (Sir 

 J. Kirk), and thrives also in Bengal. According to notes of the late 

 Mr. Thozet, a trunk 40 feet long and 20 inches in diameter broke 

 after a flexion of 17 inches, under a pressure of 49 tons. This species 

 combines with the ordinary qualities of many Eucalypts the advantage 

 of yielding from its leaves a rather large supply of volatile oil 

 (slightly more than one per cent.) of excellent lemon-like fragrance, 

 in which respect it has, among about 120 species of Eucalypts, only 

 one rival. Very closely allied to E. maculata, and perhaps only a 

 variety. Particularly adapted for a tropical jungle-clime. 



Eucalyptus cordata, La Billardtere. 



Southern Tasmania. Maximum height, 50 feet; flowering in a 

 shrubby state already. The variety E. urnigera (J. Hooker) is par- 

 ticularly hardy, and may become of sanitary importance to colder 

 countries in malarian regions, the foliage being much imbued with 

 antiseptic oil. Greatest height of E. urnigera 150 feet; stem 

 diameter to 6 feet (Abbott). 



Eucalyptus cornuta, La Billardtere.* 



The Yate-tree of South- Western Australia. A large tree of rapid 

 growth, preferring a somewhat humid soil. The wood is used for 

 various artisans' work, and preferred there for the strongest shafts and 

 frames of carts and other work requiring hardness, toughness and 

 elasticity, and is considered equal to ordinary ash-wood. The tree 

 appears 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 suffer in the rainy 

 season like many other Eucalypts. The dry wood sinks in water. 

 E. occidentalis (Endlicher) is the flat-topped Yate, an allied and 

 equally valuable species of South- Western Australia.
