E. obliqua, E. amygdalina, and many other fissile kinds ; the transverse strength is about 

 equal to that of English oak. Used for heavy scantlings in house-building, for ship- 

 building, for carriage-building, for telegraph-poles, and for planking for bridges and 

 jetties ; formerly largely used for railway sleepers and for structures in water, but the 

 wood of E. rostrata is now preferred for these purposes (F. Mueller}. Density, 0.845 to 

 1/096 (air dried). Plantations of Blue Gum have been found, in Italy and elsewhere, to 

 be of great hygienic value in fever-stricken districts. Introduced at the Cape in 1828 by 

 Sir Lowry Cole from Mauritius. Suitable for planting between 2,000 and 4,500 feet. 



Eucalyptus Leucoxylon, F. v. Mueller. The Ironbark-tree of Victoria and 

 some parts of South Australia and New South Wales. A large tree, exceptionally 200 

 feet high. Wood heavy, very hard, tough, very strong and durable ; colour pale reddish- 

 brown ; density 0'91 ; used for wbeelwork, shafts, poles,- railway sleepers, in ship- 

 building for treenails, topsides aud the stock of rudders, in mining work, and for other 

 purposes. The bark is rich in kino tannin, yielding up to 22 per cent, when fresh, but 

 is only available for inferior leather. Suitable for planting between 1,000 and 3,500 feet. 



Eucalyptus longifolia, Link. The Wooly Butt of Extra-tropic East Australia. 

 A large tree, exceptionally 200 feet high. Wood, heavy, durable ; used for fuel and by 

 wheelwrights, but often traversed by kino-sediments. Dry bark contains 8'3 per cent, 

 tannic, and 2-3 per cent, gallic acid (Procter}. Suitable for planting between 1,500 and 

 3,500 feet. 



Eucalyptus marglnata, Smith. The Jarrah of South Western Australia. A 

 large tree 100 feet high ; exceptionally 11 feet in diameter, and 150 feet high ; thriving in 

 a variety of soils and situations, but not in hot and dry stations ; found in a belt within 

 50 miles of the coast ; naturally associated with E. calophylla. Wood heavy, moderately 

 hard, easily worked, extremely durable, and taking a beautiful polish ; density I'OIO (air 

 dried) ; used for jetties, underground work, telegraph poles, railway sleepers, ship- 

 building, flooring, rafters, shingles and for furniture. Jarrah ranks with Live Oak, Teak, 

 and Greenheart, as one of the most durable and generally serviceable timbers extant. 

 Growth much less rapid than that of the Blue Gum. Suitable for planting between 1,000 

 and 2,500 feet. 



Eucalyptus Obliqua, L'Heritier. The Stringy Bark of Tasmania and Messmate 

 of Victoria. A very large tree, attaining a height of 300 feet, and a diameter of 10 feet, 

 found chiefly on mountain ranges. The most gregarious of all Eucalypts, according 'to 

 Sir F. von Mueller. Wood heavy, moderately hard, easily worked, and very fissile, but 

 not very durable underground ; light coloured ; density 0'82 ; supplies a large portion of 

 the ordinary sawn hardwood timber for rough building and for work not to be sunk 

 underground, nor requiring great strength or elasticity ; split into fence-rails, palings and 

 shingles (Mueller}. Growth rapid. Suitable for planting between 2,000 and 4,500 feet. 



Eucalyptus robusta, Smith. The Sw.imp Mahogany of New South Wales. A 

 large tree attaining a height of 100 feet and a diameter of 4 feet, preferring wet localities. 

 Wood heavy, moderately strong, but rather brittle, durable, not attacked by insects ; 

 colour light red ; density 0*82 ; used largely for posts, joists and sleepers ; also for ship- 

 building and wheelwright's work. Growth rapid. Suitable for planting between 1,000 

 and 3,000 feet. 



Eucalyptus rostrata, Schlechtendal. The Red Gum of Southern Australia. 

 Found in moist ground with a clayey subsoil ; also on river flats in the interior of the 

 Australian continent ; will thrive in ground periodically inundated, or slightly saline. A 

 large tree TOO feet high, exceptionally 14 feet in diameter and 250 feet high. Wood 

 heavy, hard, strong and extremely durable, either above or under ground or in water ; 

 colour dark reddish brown ; density 0*83 ; used for railway sleepers, telegraph poles, 

 posts, piles, bridge planks, culverts, in shipbuilding, and for felloes. Growth more 

 rapid than that of E. marginata, but slower than that of E. Globulus. Suitable for 

 planting up to 3,000 feet. 



Liriodendron tulipifera, Linnaeus. The Tulip of the United States. One of 

 the largest and most valuable trees of the Atlantic region ; 90 to 190 feet high, 6 to 12 

 feet in diameter. Wood light, soft, not very strong, rather brittle, fine grained and 

 compact, easily worked ; colour light yellow or brown ; sapwood thin ; density 0*423 ; 

 largely sawn into lumber, and used for building, for bridges, furniture, carriage building, 

 shingles, in boat building, and for other purposes (Sargent). Difficult to transplant. 

 Growth rapid. Suitable for planting up to 5,000 feet.
