196 Select Plants for Industrial Culture and 



The flowers are sought by bees, even more eagerly than those of 

 most other Eucalypts, the resulting honey being excellent [Cole- 

 man]. E. Leucoxylon has, next to E. rostrata, thriven best about 

 Lucknow, in India, among the species tried there for forest-culture. 

 E. Sideroxylon is a synonym, referring particularly to the rough- 

 barked variety. For quickly withdrawing the sap from freshly felled 

 timber in Switzerland the Rieser-process was invented ; it consists 

 in the wood being at once steamed and then kiln-dried, losses in 

 timber through cracking or deterioration through warping being thus 

 avoided. Mr. R. A. Robertson, in Victoria, has availed himself 

 already of the patent. Eucalyptus- wood can in this way be used for 

 casks, tools and other purposes far more advantageously, and gets also 

 better workable, though for underground applications perhaps too 

 much of the preservative principle may get removed. 



Eucalyptus longifolia, Link.* 



Extra-tropic Eastern Australia. A tree, known as the Woolly 

 Butt, under favorable circumstances reaching 200 feet in height, the 

 stem attaining a great girth. Mr. J. Reader asserts that there is not 

 extant a more useful timber ; it stands well in any situation. Weight 

 of a cubic foot of absolutely dry wood about 68^ Ibs., equal to 

 specific gravity 1'107 [F. v. Mueller and Rummel]. The tree thrives 

 well at the city of Algiers [Prof. Bourlier], 



Eucalyptus loxophleba, Bentham.* 



The York-Gumtree of extra-tropic West-Australia. Found natu- 

 rally in fertile soil, where it is comparatively quick in growth ; it 

 readily shoots again from stumps [G-. F. Best]. Attains a height of 

 about 100 feet, the stem a diameter of 4 feet. The wood is very 

 tough, and preferably sought in West- Australia for naves and felloes; 

 even when dry it is heavier than water. This species passes almost 

 into the earlier known E. fcecunda (Endlicher). 



Eucalyptus macrorrhyncha, F. v. Mueller.* 



The common Stringybark-tree of Victoria, not extending far into 

 New South Walew This tree attains a height of 120 feet, and is 

 generally found growing on sterile ridges ; to some degree frost- 

 bearing. The wood, which contains a good deal of kino is used for 

 joists, keels of boats, fence-rails, and rough building-purposes, also 

 extensively for fuel. The fibrous dark-brown bark serves for roofs 

 of huts, and also fpr rough tying. The wood proved in our experi- 

 ments here nearly as strong as that of E. globulus and E. rostrata, 

 and considerably stronger than that of E. obliqua. The fresh bark 

 contains from 11 to 14 per cent, of pure kino-tannic acid [F. v. M. 

 and Rummel]. The kino contains about 72 per cent, of tannin. It 

 is soluble in water as well as in alcohol [Maiden].
