tree of such celerity in growth and of such vast final dimensions 

 wants necessarily soil open to great depth for full scope to its 

 roots, to attain unimpaired development. Mr. T. Waugh observed 

 in South-Island, New Zealand, that plants, raised from locally 

 ripened seeds, proved hardier than those raised from Australian 

 ordinary seed. The province of Roussillon, after its thousands of 

 years of history, became in the aspect of its landscape completely 

 changed within the last few years through Prof. Naudin extending 

 therto also copiously E. globulus. At the height of 2,500 feet on 

 the base of the South-European Alps and in localities too cold for 

 olive-culture, E. globulus grew to 70 feet high in seven years 

 [Naudin] . Regarding the comparative strength of this and various 

 other timbers, the result of the tests, instituted and tabulated by 

 the Carriage-timber Board of the Victorian Railway Department, 

 much under the leading of Mr. Clement Hodgkinson, may be referred 

 to in the Progress Reports of the Victorian Royal Commission on 

 Vegetable Products [p. 477-490]. Colonel Warren, reports from 

 San Francisco, that branchlets of Eucalypts will drive mosquitos 

 and other insects out of rooms. 



Eucalyptus g-omphocephala, Be Candolle.* 



The Tooart of South- Western Australia ; attains a height of 120 

 feet, the clear trunk a length of 50 feet. The wood is tough, heavy 

 and rigid, the texture close and the grain so twisted, as to make it 

 difficult to cleave. It shrinks but little, does not split while under- 

 going the process of seasoning, and is altogether remarkably free 

 from defects. It will bear exposure to all vicissitudes of weather 

 for a long time, and is particularly valuable for large scantling, 

 where great strength is needed ; in ship-building it is used for beams, 

 keelsons, stern-posts, engine-bearers and other work below the 

 floatation ; recommendable also for supports of bridges, framing of 

 dock-gates and for wheelwrights' work ; indeed it is one of the 

 strongest woods known, whether tried transversly or otherwise 

 [Laslett]. Grew in seven years to a good-sized tree in South-France, 

 and so did the following species, as well as E. diversicolor, E. 

 botryoides, E. Gunnii, E. polyanthema and E. viminalis [Naudin]. 

 This species, as well as E. odorata, E. fcecunda and E. decipiens, 

 thrive best in limestone-soil. 



Eucalyptus gfoniocalyx, F. v. Mueller.* 



Generally known as Bastard-Boxtree and occasionally as Spotted 

 Gumtree. From Cape Otway to the Southern parts of New South 

 Wales, rare near St. Vincent's Gulf [McEwin] and Flinders Range 

 [J. E. Brown]. Ascends to 4,000 feet, and attains ex- 

 ceptionally a height of 300 feet. Thrives well near the city of 

 Algiers [Professor Bourlier]. Should be included among those 

 for Eucalyptus-plantations. Its wood resembles in many respects 

 that of E. globulus, and is comparatively speaking easily worked. 

 For house-building, fence-rails and similar purposes it is extensively
