DISTILLATION OF THE OIL.

Because of the strong camphoraceous odor and its close relationship to

the camphor tree, the extraction and possible utilization of the oil

from this wild aromatic plant suggested itself. Accordingly, during the

summer of 1910, with the assistance of Mr. S. C. Hood, in charge of

the station at Orange City, Fla., a small quantity of the leaves and

twigs of this plant was distilled and a yield of about 0.2 per cent of

oil was obtained. But with proper conditions and precautions the yield

could no doubt be very materially increased, depending largely upon the

time at which the distillation is made, and also upon the proportion

of twigs and branches included. The above distillation was made late

in the summer, long after the blossoming period, the stage at which a

plant is usually most productive in volatile oils, and the material

also contained many branches and much woody matter.

The oil obtained was pale yellowish brown in color, with a strongly

aromatic and camphoraceous odor, and a persistent bitter, slightly

pungent, and camphorlike taste. The specific gravity at 25° C. was

0.9272; specific rotation, A_{D} = +22.4°; refraction, N_{D} 25° =

1.4695. The oil was soluble in one-third its volume of 80 per cent

alcohol, becoming faintly turbid upon the addition of five volumes or

more of alcohol.
