42 Statistical Data on the Area of Asiatic Russia. [No. 1, 



(5.) The map of the countries of the Amoor river and of por- 

 tions of the Lena and Yenisei rivers. — S chwartz, published by 

 the Eussian Geographical Society in 18G3. 



(6.) The map of the Khanat of Kokan, constructed by Mr. 

 V enuiko f himself in 1861. From this map he obtained the 

 area of the Trans-Chui country. 



In compiling his statistics, Mr. Yenuikof adopted the fol- 

 lowing limits : — 



In the North — the Ocean ; the islands therein situated are esti- 

 mated separately, and necessarily only approximately, their outlines 

 being but imperfectly known, as are those also of the Taimyr pen- 

 insula. 



In the East — the Pacific Ocean from the embouchure of the Tu- 

 men-Ula to Behring's Straits. Here the areas of the Islands are 

 more accurately computed. The Island of St. Lawrence does not 

 enter into his calculations. 



In the South, — the Caspian Sea from the mouth of the Ural to 

 44° of latitude ; the 44th parallel ; the northern shore of the Sea 

 of Aral, and the Jaxartes. With reference, however, to this por- 

 tion of the Steppe, Mr. Yenuikof made use of the known re- 

 sults of former calculations. Those lands of which he has freshly 

 calculated the areas, are bounded in the south by the rivers Chui, 

 Kostekara, the upper course of the Jaxartes, Karkara and Charyu, 

 and by the conditional frontier line along Drungaria and Mongo- 

 lia — as traced on the maps — to the Argun, Amoor, Tungachan, 

 and to the Tumen-Ula. 



In the West, — the Ural Mountains, the boundaries of the Go- 

 vernments of Peru and Orenburg, and the region of the Orenburg 

 Kirghizes to lake Telekul. Although Mr. Y e n n i k o f has not 

 himself calculated the areas of the Steppes of the little horde of 

 Kirghizes, that having been done with sufficient accuracy at the 

 General Staff, he has, from the sum total of these areas, deducted 

 the figure for that portion of the Steppes which is apportioned to the 

 Kirghizes of the Jaxartes. By the Trans-Chui region, he compre- 

 hends the country between the Chui and the Talus extending to a 

 line connecting Aulieta with Turkistan.
