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

 oil of excellent lemon-like fragrance." 



E. GOMPHOCEPHALA, Candolle, grows to a height of " fifty feet, 

 wood close grained, hard and not rending." 



Eucalyptus marginata, Smith. " The Jarrah or mahogany 

 tree of S. W. Australia, famed for its indestructible wood, which is 

 attacked neither by Chelura nor Teredo nor Termites, and therefore 

 so much sought for jetties and other structures exposed to seawater, 

 also for underground work, and largely exported for railway sleepers. 

 Vessels built of this timber have been enabled to do away with cop- 

 per-plating. It is very strong, of a close grain and a slightly oily 

 and resinous nature ; it works well, makes a fine finish, and is by 

 shipbuilders here considered superior to either Oak, Teak, or indeed 

 any other wood." The tree does not grow as rapidly as the Blue 

 Gum in the neighborhood of Melbourne, but Dr. Mueller expresses 

 the opinion that it would make a rapid growth in a more favorable 

 locality. 



The E. ROSTRATA, Schlecht, the Red Gum of Yictoria, is a 

 very valuable species for the " extraordinary endurance of the Avood 

 underground, and for this reason highly valued for fence-posts, piles 

 and railway sleepers ; for the latter it will last a dozen years, and if 

 well selected much longer. It is also extensively used by shipbuild- 

 ers, for mainstem, sternpost, innerpost, deadwood, floor timbers, 

 futtocks, transoms, knightheads, hawsepieces, cant, stern, quarter 

 and fashion timber, bottom planks, breasthooks and riders, windlass, 

 bowrails, etc. It should be steamed before it is worked for plank- 

 'm<r. Next to the Jarrah from W. Australia," this is the best 

 wood for resisting the attacks of seaworms and white ants. This 

 species reaches a hundred feet in height, which is also the height of 

 the next and last of the Eucalypti referred to herein, viz: E. 

 SIDEROXYLON, Cu7in., which produces a wood of great strength and 

 hardness, and desirable for carpenters, shipbuilders, and wagon- 

 makers, being suitable for wheels, treenails, belaying pins, and is con- 

 sidered the strongest wood in the colony ; also valuable for railway 

 sleepers, underground work in mines, etc. 



The wood of the Gums is " so soft at first as to render the felling, 

 splitting, and sawing up of the tree, when green, a very easy pro- 

 cess, but when thoroughly dry becoming as hard as oak."*
