tion, having germinated on the way. On their receipt the seedlings 
were immediately transplanted into pots. 
The Berjan forest reserve, situated near Rangagora, is devoid of 
Taraktogenos kurzii, but does contain Gynocardia odorata. The lat- 
ter tree is associated with Terminalia myriocarpa, Artocarpus 
chaplasha, Gmelina arborea, Cinnamonum cecidodaphne, Morns 
laevigata, Mesua ferrea, Bombax malabaricum, Canarium bengalense r 
Premna bengalensis, Myristica assamica, Ficus elastica, Kydia caly- 
cina, Macaranga indica, Heteropanax fragrans, Stereospermum 
chelonoides, Sterculia villosa, and Eugenia praecox. Other trees 
growing here include Terminalia bellerica, T. chebula, and T. 
foetidissima. 
The main tree in the forest of the Berjan reserve is a species of 
Yatica, which has as undergrowth young seedlings of the same spe- 
cies. The outskirts of and the approach to the Berjan forest reserve 
are mainly occupied by a tall timber bamboo, Dendrocalamus hamil- 
tonii, with huge culms spreading from a common base in all direc- 
tions, making walking very difficult. 
CONCLUSIONS. 
The facts brought to light in this recent survey show that the 
dealers in chaulmoogra oil (that derived from Taraktogenos kurzii) 
have never seen the tree in its wild state. Even the native Bengal 
dealers in Chittagong had not been in the forests of the Chittagong 
Hill tracts. All depend on jungle people for collecting the seeds, 
which are known by different native names in the various regions 
in which they grow. Smith, Stanistreet & Co., of Calcutta, claimed 
to have a tree growing in their compound, but on examination it was 
found not even to belong to the family Flacourtiacese, to which Ta- 
raktogenos belongs. The collecting of the seeds is, then, in the hands 
of jungle people, who are more or less indolent. Moreover, the con- 
ditions under which these seeds are collected are such, as has already 
been explained, that at least 50 per cent of the crop is lost every 
year. The Burmese name kalaw is applied to more than one species, 
and these species resemble each other so closely that the jungle people 
make no distinction between them (PI. XV). Seeds of these trees 
are sent to markets and bazaars under the collective name of kalaw, 
where they are bought up by dealers who manufacture chaulmoogra 
oil from them. 
Another point of interest and one of which very little is known 
is that Taraktogenos kurzii and kindred species do not bear a reg- 
ular yearly crop but fruit sporadically and sometimes are without 
fruit for two years or more. The natives stated that fruit is col- 
lected by them every three years. The causes of the irregular fruit-
