bloom presents a very pleasing appearance. The bark of the trunk 

 and branches is persistent, somewhat furrowed, and grayish in color. 

 This species thrives under a great variety of climatic conditions. 

 It grows at and near the coast, in the foothills, on the mountain 

 sides, and in the hot, dry valleys of the interior. The timber of this 

 tree is very hard, strong, and durable, being used in Australia for 

 railroad ties, for cogs, and for the parts of wheels. It also makes an 

 excellent fuel. Its habit of growth and pleasing aspect render it 

 a good shade tree. It can also be used as a windbreak in localities 

 where faster growing trees will not endure the climatic conditions.

38723. Eucalyptus amygdalina Labill. Peppermint gum. 



In its native country the individuals of this species are the tallest 

 of the genus. This eucalyptus is one of the most remarkable and 

 important of all plants. Viewed in its marvelous height w^hen 

 standing forth in its fullest development on the slopes or within 

 glens of mountain forests, it represents probably the tallest of all 

 the trees of the globe. Considered as a hardwood tree of celerity 

 in growth, it ranks among the very foremost. The tree endures low 

 temperatures, but is injured by dry heat. It does best neai- the 

 coast and at moderate elevations in well-watered mountain regions. 

 The timber is not as valuable as that of many other eucalypts, but 

 is said to be useful for shingles, rails, and for planking ships. It is 

 comparatively light, unlike many other eucalypts, floating on water. 

 It does not usually last well underground, nor does it furnish fuel 

 of good quality. The leaves are a source of eucalyptus oil. {Mc- 

 Clatchie, p. 51, 52.) 



38724. Eucalyptus resinifera Smith. Kino eucalypt. 

 This is a tree of fair size, when full grown, reaching a height 



of 100 feet. It is usually erect and symmetrical. The bark of the 

 trunk is dark reddish, fibrous, and persistent, resembling consider- 

 ably that of the stringy barks. The bark of the branches is more 

 or less deciduous. The wood is a rich red color, resembling true 

 mahogany, and is very heavy. This Eucalyptus, known as the red 

 mahogany, grows quite well in the coast regions of California, but 

 does not thrive in the dry interior valleys. It does not resist severe 

 frosts, nor does it endure high temperatures in a dry atmosphere. 

 The tree furnishes a timber that is very strong, hard, and durable. 

 It is used in Australia for piles, posts, paving, shingles, and general 

 building purposes. (McClatchie, p. 74, 75.) 



38725. Eucalyptus longirosteis Muell. Red gum. 

 (Eucalyptus rostrata Schlecht.) 



Individuals of this species make a fairly rapid growth and are 

 commonly above medium size. The tree varies considerably in habit 

 and appearance, in some cases being erect and stately and in other 

 cases unsymmetrical and irregular in growth. This red gum is one 

 of the leading forest trees of the Australian continent. The tree 

 Is commonly about 100 feet high in Australia, but is reported under 

 favorable circumstances to grow to double that height, with a trunk 

 diameter of 6 to 12 feet. The red gum grows under a great variety
