EEPORT OP THE SECEETAEY. IL 



mouth of the Rejang River. Here I engaged three Malays and their canoe tO' 

 take me 80 miles up the river to the island of Sibu. * * * A little Malay 

 river steamer arrived and took me 90 miles farther up the river — as far as it 

 could go. At this head of navigation is a little native town called Kapit, and 

 here I again took to dugout canoes, this time for good and all. * * * jt 

 took me two months to ascend this river to its headwaters. I collected 

 specimens of reptiles and mammals, together with interesting anthropological 

 specimens, took photographs of all kinds, studied the natives, the rivers, the 

 weather, vegetable life in general, made notes on everything, and mapped 

 my course as accurately as I could with the instruments in my possession. 

 * * * I crossed the main range of mountains forming the backbone of 

 Borneo to the headwaters of the Kajan River. I estimate the altitude of the 

 pass through which I crossed the mountains at a little over 3,000 feet. * * * 

 [He then proceeded] in dugout canoes down one branch of the Kajan River 

 and up the main river for several days to the immense village of Long Nawong. 

 This village comprises about 3,000 souls, ruled by a native rajah, who visited 

 me and with whom I exchanged presents. Here I set out with one canoe and 

 five head-hunters as paddlers and continued up the Kajan River. A flood 

 arose, my canoe went to the bottom, and we had to swim for shore. I saved 

 my rifle and my tin box of maps, papers, diaries, and notes. 



Continuing on foot up the river we fell in with a party of 40 head-hunters 

 of the Bahau Tribe and I arranged to travel with them, sending back my five 

 Kajan paddlers. With this Bahau troupe I continued up the Kajan River 

 to its headwaters and over another range of mountains to the headwaters, 

 of the Mahakam River. * * * After losing my collection I immediately 

 began a second collection, and this assumed the proportions of the first as I 

 proceeded. When within about 500 miles of the mouth of the Mahakam River 

 I came to the first outpost of civilization, the Dutch military post of Long- 

 Iram, in charge of a Dutch captain and a company of native Javanese. Upon 

 hearing my story the captain promised to send a military expedition up into the 

 interior, where the Dutch had never been before, and try and secure the outfit 

 which I had left at these native villages. * * * i boarded a little flat- 

 bottomed Malay river steamer, which * * * floated on down the river to- 

 the coast. 



LYMAN SIBERIAN EXPEDITION. 



The expedition to the Altai Mountains, which was financed by Dr.. 

 Theodore Lyman, of 'Cambridge, Mass., as mentioned in my last 

 report, returned to Washington September 16, 1912. Mr. Ned 

 Hollister, a naturalist of the National Museum, accompanied Dr. 

 Lyman. The expedition resulted in securing 350 mammals for the 

 National Museum and 300 birds for the Museum of Comparative 

 Zoology, Cambridge. The region covered was in the Kurai dis- 

 trict, Government of Tomsk. The mammal collection is one of the 

 most^important received in recent years, as the region had not been 

 represented in the Museum, and the fauna was of special interest 

 on account of its close relationship with that of North America. 



ANTHROPOLOGICAL STUDIES IN SIBERIA AND MONGOLIA. 



With the view of securing further information as to the origin of 

 the race that peopled America, a visit was made to certain portions of
