The orange, date-palm and eucalyptus have been acclimatized on the coast of Provence and the Riviera.
Directing a river so that it may deposit its sedimentary matter in the lower-lying parts, thus levelling them up and consolidating them, and then leading the water away again by drainage; (iii.) the planting of firs and eucalyptus trees, e.g.
The planting of eucalyptus trees is out of favour at present, but it appears to have been successful in Portugal, not from any prophylactic virtues in the plant, but through the great absorption of moisture by its deep roots, which tends to dry the subsoil.

Of trees now extinct in America, Eucalyptus and Ginkgo are perhaps the most noticeable.
The Australian Eucalyptus and Casuarina in great variety, and many other imported trees, including syringas, wattles, acacias, willows, pines, cypress, cork and oak all thrive when properly planted and protected from grass fires.
The eucalyptus is of quite modern introduction; it has been extensively planted in malarious districts.
On the eastern side the plains and rocky ridges, where not artificially cleared, are occupied by shaggy and often sombre forests mainly composed of the following genera: Eucalyptus (gum tree), Casuarina, Bursaria, Acacia, Leptospermum, Drimys, Melaleuca, Dodonaea, Notolea, Exocarpus, Hakea, Epacris, Xanthorrhoea, Frenela.
In length, and of an ash-grey colour, an excellent climber, residing generally in lofty eucalyptus trees, the buds and tender shoots of which form its principal food, though occasionally it descends to the ground in the night in search of roots.
The mere enumeration of the genera will indicate how close the flowering plants are to living forms.
