therefore of the utmost practical importance to Foresters and others 
who deal with the protection and propagation of sandalwood to care- 
fully investigate and ascertain which species of plants it likes best 
and which of them help to produce the largest quantity and the best 
quality of scented wood. 
2. I have attempted to study this question for some time oast 
by my own observations and from those of othei's who have devoted 
attention to this subject. The results of that study are embodied 
in the following pages. They are by no means exhaustive or con- 
clusive and require to be tested and verified by further investigation 
and observation by others who are interested in the subject, and 
that is the object of the publication of these notes in spite of their 
admitted incompleteness. 
3 The investigations made during recent years into the natural 
histoiy of sandalwood by Dr. Barber, M.A., Sc.D., F.L.S., and the 
writer's study of its root system in the Salem, Kurnool and Banga- 
lore Districts and elsewhere, and the observations recorded by some 
Forest Officers such as the late Mr. Eicketts of the Mysore service, 
Mr. P. M. Lushington and a few others have confirmed and estab- 
lished beyond all doubt the correctness of Mr. Scott’s discovery in 
1871 that the sandal plant is a root-parasite. Dr. Barber’s and 
my own studies further indicate that this species depends entirely 
for its root-nourishment upon other species of plants in its neigh- 
bourhood without which it cannot live or grow. This latter state- 
ment does not appear to have been made hitherto in an authoritative 
and unqualified manner, but it seems to be justified by the evidence 
collected from Dr. Barber’s pot-culture of sandal seedlings, from 
a series of experiments made by me in the Kurnool District in 
190G and 1907, and from other recorded observations. The avail- 
able evidence is briefly set forth below: — 
({) Inability of pure-grown sandal seedlings to grow and develop 
after the reserve materials stored in the seed and subsequently 
transferred to the hypocotyl are exhausted. 
This was found to be the case in four separate experiments made 
by me at Kurnool and Diguvametta by raising seedlings in nursery 
beds, pot-tiles, bamboo tubes and dealwood boxes. In aB the 
experiments, the seedlings, una^sociated with other .species, died
