August 8, crossed the Naivasha Plains and the Aberdare Mountains, 

 and reached Nyeri on August 11. Operations were carried on m this 

 northern country until late in October. The party, as before, 

 divided as seemed best to cover the ground thoroughJy, and the 

 Laikipia Plateau, Northern Guaso Nyiro, and Mount Kcnia regions 

 were very carefully worked. 



The next region to be covered was the Guas Ngishu Plateau. 

 Leaving Nairobi on October 25 the expedition moved westward over 

 the railroad to Londiana. The next day the safari left Londiana 

 and moved northward toward Ravine. The Elgeyo Escarpment 

 and Guas Ngishu Plateau were worked in a manner similar to the 

 other regions, and much collecting was done, especially along the 

 Nzoia River. The return to the railroad was made in late November. 

 During the first half of December much miscellaneous collecting was 

 done by the members of the expedition at various points along the 

 railway. This included a special trip by Kermit Roosevelt to the 

 coast region below Mombasa for sable antelopes. 



On December 18 the expedition left Nairobi on the railway for 

 Victoria Nyanza. The lake was crossed to Entebbe and headquarters 

 established at Kampala December 21. March was made across 

 Uganda by way of Hoima to Butiaba, which was reached January 5, 

 1910. The journey down the Nile nov/ began and the expedition 

 reached Wadelai on Januaiy 8. From here a special trip into the 

 Lado Enclave was made. The principal object of this trip v/as the 

 white rhinoceros, but aU the members of the expedition made the 

 most of the opportunity and gathered large collections. Tlie journey 

 down the Nile, by boat and by land, was resumed on February 3, 

 and collections were made at every opportunity. Gondokoro was 

 reached on February 17. While the small mammal and bird col- 

 lectors remained in the vicinity of Gondokoro Colonel Roosevelt led 

 an expedition on a side trip across the Nile and inland from Rejaf after 

 giant elands. The northward journey was resumed on February 28; 

 collections were made at frequent intervals and at several especially 

 important localities; and the party disbanded at Khartoum the latter 

 part of March, 1910. 



Colonel Roosevelt's preliminary report to the Secretary of the Smith- 

 sonian Institution, dated Khartoum, March 15, 1910, was as follows:' 



I have the honor to report that the Smithsonian African expedition, which was 

 intrusted to my charge, has now completed its work. Full reports will be made later 

 by the three naturalists, Messrs. Mearns, Heller, and Loriug. I send this, preliminary 

 statement to summarize what has been done; the ligures given are substantially accu- 

 rate, but they may have to be changed slightly in the final reports.
