lieves to be what is usually called
the oil of Namur. It has a very fragrant aromatic odor, slightly
resembling that of otto of roses, but not nearly so rich. Its taste is
sharp and agreeable, approaching that of oil of lemons. It has a deep
yellow color, and contains a good deal of resinous matter.

LEMON GRASS (_Andropogon schoenanthus_).--This fragrant grass, which is
now cultivated very generally throughout the West Indies, in the
gardens of the planters, as an elegant and powerful diaphoratic, was
doubtless introduced from the East. The active principle of the leaves
seems to reside in the essential oil which they contain. Lemon grass
oil forms an important article of export from Ceylon, amounting in
value to nearly L7,000 annually.

The _Andropogon schoenanthus_, which may be seen covering all the
Kandian hills, is the best possible pasture for cattle--at least as
long as it is young. This species of grass is very hard, and grows to
the height of seven feet, and sometimes higher, and has a strong but
extremely pleasant acid taste. It derives its name from having, when
crushed, an odor like that of the lemon, so strong, that after a time
it becomes quite heavy and sickening, although grateful and refreshing
at first. It covers the hills in patches--those, at least, that are
not overgrown with jungle and underwood--and it is to be found nowhere
but in the Kandian district. Spontaneous ignition frequently takes
place, and the appearance of the burning grass is described as most
magnificent. A few days after, from the midst of this parched,
blackened, and apparently dead ground, lovely young green shoots begin
to arise--for the roots of this extraordinary grass have not even
been injured, far less destroyed, by the fire; and in a very short
time the whole brow of the mountain is again overspread with tufts of
beautiful green waving grass.--("Journal of Agriculture.")

Otto of khuskhus or scented grass, from another species, _A.
digitalis_, obtained at Ulwar in the States of Rajpootanah, was shown
at the Great Exhibition in 1851, and Newar oil (from _A. maritima_)
from Agra.

CITRONELLA OIL.--In the Southern province of Ceylon some half dozen
estates about Galle are cultivated with citronella grass. The exports
of this oil from Ceylon in the last three years have been as
follows:--1850, 86,048 oz., valued at L3,344; 1851, 114,959 oz.,
valued at L3,742; in 1852, 131,780 oz., valued at L2,806.
