10 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1913. 



The Childs Frick Expedition. — As mentioned in my last report, 

 Dr. Edgar A. Mearns, United States Army, associate in zoology in 

 the National Museum, who had served on the expedition under Col. 

 Roosevelt, accompanied Mr. Childs Frick, of New York, on a hunt- 

 ing and collecting trip in the territory north of that visited by Col. 

 Roosevelt and Mr. Rainey, covering at the same time certain parts of 

 Abyssinia, northern British East Africa, and the country lying about 

 Lake Rudolf. The expedition ended in September, 1912. The col- 

 lections as a whole embraced plants, mammals, birds, reptiles, batra- 

 chians, fishes, mollusks, crustaceans, and other invertebrates. A 

 part of the large collection of birds obtained by this expedition is 

 dejDOsited in the National Museum. 



EXPLORATIONS IN BORNEO. 



Abbott Borneo expedition. — Through the generosity of Dr. W. L. 

 Abbott, who for many years was engaged in natural history and 

 ethnological investigations in the Malay Archipelago, a fund has 

 been provided for natural history field work in Dutch East Borneo. 



Nothing has been published concerning this practically unknown 

 region, and the National Museum had no collections from East 

 Borneo, although there were a few from the west and south coasts 

 of Borneo. During the past year Mr. Raven, in charge of this 

 exploration, succeeded in securing a very interesting series of the 

 characteristic mammals of the country, such as orangs, deer, wild 

 pigs, squirrels and smaller rodents, and other interesting species. 



Dr. Streeter''s exploration in Borneo. — Mr. Daniel Denison Streeter, 

 jr., of Brooklyn, having offered his services as a collaborator in 

 zoolog}' of the National Museum, sailed from New York on April 4, 

 1912, and returned December 24, 1912. Some of his thrilling experi- 

 ences in the interior of Borneo are described in his interesting report 

 to the Institution. He passed from Sarawak into Dutch Borneo 

 by ascending the Rejang River and crossing the mountains on the 

 dividing line to the Kajan River. He then ascended to the head 

 of this river and crossed another range to the headwaters of the 

 Mahakam River, which he descended to the Strait of Macassar. 

 During his trip he secured some interesting collections of mammals, 

 reptiles, and anthropological specimens, part of which have been 

 received by the Museum, but many additional specimens were neces- 

 sarily left behind in the mountains and may not be recovered. 



In describing his journey Mr. Streeter writes: 



Arriving at Kuehing, the capital of the Kingdom of Sarawak, in north- 

 western Borneo. I apprised the officials of nay plan to cross Borneo. They 

 helped me with every means in their power, although they told me that no man 

 had ever yet Iteen across Borneo, and that they did not think it possible for me 

 to do it. * * * T crossed a bay 200 miles wide in a Chinese junk to the
