NOTES ON SCENT-YIELDING PLANTS. 
By “NAT SINE.” 
Te following preliminary notes on scent-farming in Queensland have been 
kindly furnished to the Journal by a gentleman who is engaged in the industry 
in the Southern part of the colony :— 
In a future issue we shall publish “ Nat’s ” personal experience in scent- 
farming. 
The following notes on scent plants have been written with the hope 
that they may prove of some slight use to anyone thinking of starting scent- 
farming in Queensland. 
To settlers on the rich scrub lands of our Southern coastal ranges, where 
cost of carriage precludes the possibility of ordinary heavy crops being profit- 
ably produced, the perfume industry particularly recommends itself, on 
account of the smallness in bulk of its products when compared value for 
value with other produce. : 
The following notes include the names of such plants only as are likely to 
grow to perfection on the high lands of Southern Queensland: 
For conyenience’ sake the names of plants are given in alphabetical order, 
the first on the list being :— 
Acactra Farnesrana.—This plant, better known as Cassie, is grown 
extensively in the South of France, where it thrives better than anywhere else 
in Europe. It also grows well in'the vicinity of Brisbane, and may even be 
found growing as far north as the valley of the Flinders River, above 
Hughenden, where its flowers shed a perfume of intense swectness. 
"The young trees are generally raised from seed in prepared beds, and 
when about 2 or 3 feet in height are transplanted at distances of about 12 feet 
each way into well-worked land. 
The flowers come to maturity in succession along the branches, which is of 
great advantage to the grower, one lot of blossoms being disposed of before 
the others are fit to gather. 
The perfume is procured by successive maceration of the fresh flowers 
in purified fat, kept in a liquid condition by gentle heat. After standing for 
from twelve to forty-eight hours, the spent blossoms are strained from the 
fat, to which fresh are added. ‘This process is repeated ten or fifteen times, 
till the required strength of perfume is obtained. 
In France matured trees yield flowers to the value of from £30 to £40 
per acre. The perfumed fat would probably find a ready sale at about 12s. 
per lb. 
Brroamor.—This useful perfume is obtained from the rind of the fruit of 
Citrus bergamia, either by expression or distillation, and is so much in demand 
that the production fails very short of requirements. It is in consequence 
largely adulterated. ; : 
One thousand fruit will yield about 30 oz. of oil, which when pure is 
worth from £1 10s. to £2 per lb. 
This oil is produced near Palermo, in Sicily, and is worthy of the attention 
of orange-growers in Queensland. 
The tree requires much the same treatment as the orange, and is generally 
planted about 12 feet each way.
