146 QUEENSLAND AGRICULTURAL JOURNAL. [1 Fes., 1898. 
An acre of lavender on good soil will require about 5,000 plants. The 
third year every 100 plants will average 1 |b. of oil, thus giving an average of 
50 lb. of oil, worth $2°50 (10s. 5d.) per lb.; cost of working is about £5 per acre. 
This will leave a profit of some £20 per acre. Over 1,000 tons of Rose de 
Grasse (the only rose of any commercial value) are grown annually at Grasse 
in France, and this enornious quantity is still not sufficient to meet the 
demands of the foreign markets. The treatment of this rose is so simple and 
expeditious that, when properly known and understood, thousands of acres of 
ground will be cultivated with this beautiful specics of the rose family. 
With respect to those who want to go into the business and want an 
immediate return, they should grow mignonette in large quantities, violets, 
‘tuberoses, jonquils, boronia, &. These can be treated the same year by the 
simple processes of extraction with fat as above described, and meantime they 
can be propagating lavender, roses, geraniums, which take more than one 
season to provide material for. 
HINTS. 
Never grow plots of flowers too close to each other. If you group several 
various kinds of scent plants too near together—as lavender here, pennyroyal 
next door—each will become tainted one with the other, and the virgin aroma 
of each will be confused. An acre of roses or jasmine should be separated by 
an acre of potatoes or cabbage. 
The plants should be planted in rows running north and south, so as to 
get the greatest benefit from the sunshine. On the influence of the sun 
depends largely the superiority of the oil extracted. 
WILL THE INDUSTRY PAY? 
With Mr. G. M. Stratton, the writer of the preceding article, we say :— 
It is hard to tell, as so many scents are manufactured by chemical combina- 
tions. The violet, heliotrope, lilac, and many others are manufactured by 
chemicals so perfectly that none but experts can tell the difference between 
the true or the spurious article. Some exquisite scents are said to be pre- 
pared from the drainage of cow-houses! As an adjunct to ordinary orchard 
or farm business, scent-making wiil, however, always provide a nice little sum 
of pocket-money for young members of the family. A few pounds of fat and 
a few sheets of glass are all the appliances required, and these are cheap 
enough in Queensland. ‘The rest is only light and pleasing work, only taking 
up a very short part of the early morning hours. ‘Ihe saturated lard is worth 
from £1 5s. to £1 10s. per Ib. in London or Paris, and the spirit, which in 
the articte we quote is called “ extract,’ is worth 3s. 6d. per oz. or £3 10s. 
per pint.
