THE CHAULMOOGEA TREE AND RELATED SPECIES. 19 



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, 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 hurzii 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 

 depn it h standing water, the tracks of wild elephants.
