the forests. Tigers wreak havoc in these jungle villages by carrying 
off bullocks, and often, as was the case during the writer's visit at 
Kyokta, human beings. A tiger followed the writer and 31 coolies 
in broad daylight for a whole day up the creek bed into the kalaw 
forests. Returning during the following night, the beast killed three 
women and a 2-year-old child. 
All the seed available was collected by the writer and packed in 
moist powdered charcoal in cotton bags. These were wrapped se- 
curely in strong oil paper, then in heavy manila wrapping paper, 
securely tied, and dispatched from Mawlaik to Honolulu, Washing- 
ton, D. C.j the Philippines, and Singapore. The seeds sent to Hono- 
lulu and Washington arrived in good condition and germinated well 
in both places, the result being several thousand trees which give 
promise of becoming well established. 
The writer then returned to Rangoon and thence went to Cal- 
cutta, where he studied the type material of Hydnocarpus and Ta- 
raktogenos in the Sibpur Herbarium. These types, together with a 
number of new and undescribed species found in the collection, were 
photographed and copious notes taken. Drug firms, such as Smith, 
Stanistreet & Co. and Glen & Co., were visited. The former were 
using mainly Hydnocarpus wightiana seeds to obtain the oil from 
which they prepared the ethyl esters used by Dr. Muir for the treat- 
ment of lepers in the leprosy station of the Calcutta School of 
Tropical Medicine. Smith, Stanistreet & Co. stated that most of 
their seed of Taraktogenos kurzii was obtained from near Dibrugarh, 
in northeastern Assam. 
Dr. Muir accompanied the writer to Dibrugarh by way of Tinsukia. 
At the. forest office in Dibrugarh, the writer was informed that 
the Dibru forests contained scattered trees of Taraktogenos kurzii 
as well as of Gynocardia odorata. Arrangements were made with 
the forest office, and accompanied by a very able forest ranger, cour- 
teously provided by the main office at Shillong, the writer went 
to Tinsukia by rail and thence walked to Rangagora and beyond to 
the forest bungalow on the Dibru River. The following day the 
Dibru forest reserve was explored for Taraktogenos kurzii. This 
forest reserve is marked as the eighth in the Lakhimpur district and 
is situated between the Brahmaputra and the Dibru Rivers at be- 
tween 27° 36' and 27° 42' north latitude and 95° 15' and 95° 31' 
east longitude. The land is rather flat here, and during the rainy 
season is inundated, so that walking through it is impossible. The 
soil is not quartz sand, but loamy and much heavier and evidently 
somewhat impervious. In certain stretches, especially along the 
trail, it is quite swampy, and these stretches were full of circular 
depressions with standing water, the tracks of wild elephants.
