PRINCIPAL SPECIES OF EUCALYPTS GROWN IN AMERICA. Sl 
attractive aspect, it makes a desirable shade tree for many situations. 
As a wind-break it is also serviceable, and is a valuable source of 
honey. Asa forest cover for situations too stony and sterile for the 
faster-crowing species, it has considerable value. Railway companies 
would do well to consider the planting of this tree along portions of 
their lines running through moderately warm, dry regions, for the 
production of timber for bridges. and track repairs. 
Eucalyptus stuartiana. 
APPLE-SCENTED EUCALYPT. 
Characteristics.—The trees of this species never attain a very great 
size, but they make a comparatively rapid growth during the first 
ten years, in some cases reaching a trunk diameter of 1 foot and a 
height of 30 to 40 feet during that period. The tree usually grows 
quite erect, with a somewhat stocky appearance. The bark of the 
trunk and main branches is rough and more or less fibrous. It isofa 
grayish brown color outside and is salmon colored next the wood. 
The leaves of the young seedlings and of young suckers are opposite 
on the stem, and roundish or lance-shaped, usually having a distinct 
bloom on the surface. (See Pl. LX XXIV, c.) The later leaves are 
scattered, lance-shaped, or sickle-shaped, shiny, and equally dark green 
on the two surfaces. When crushed they give forth a pleasant odor, 
somewhat resembling that of apples. The flowers are of medium size, 
usually in compact clusters of 3 to 8. The deciduous covering of the 
flower buds is cone-shaped. The seed cases are rather small, and are 
commonly nearly top-shaped. 
Climatic requirements.—The species thrives at and near the coast, 
but does not do well in the dry, hot valleys of the interior. It endures 
minimum temperatures of 10° to 18° F., and it therefore may be 
planted in higher latitudes and at greater elevations than most species. 
Uses.—Upon account of its resistance to frost, this Eucalypt is useful 
for a forest cover, for windbreaks, and for shade in ravines and on 
fairly moist hillsides and mountains where, on account of too heavy 
winter frosts, other species would not thrive. The tree furnishes a 
timber that is hard, but, not being straight-grained, is somewhat diffi- 
cult to split. It is useful for fence posts and for fuel. According to 
Baron von Mueller, it is employed to some extent for furniture manu- - 
facture in Australia. 
Eucalyptus tereticornis. 
Forest RED Gum. 
Characteristics. —The tree attains a good size under favorable con- 
ditions, but it is commonly not much above 100 feet in height and 6 
feet in diameter in Australia. In the Southwest it makes quite a rapid
