of Tobolsk, it receives on its right the Irtyche, which, taking its departure from 

 the south, is itself increased by the Ichim and the Tobol. It afterwards divides 

 itself into two branches, which unite before its exit into the sea. 



The Jenissei has a still more considerable course, extending more than a thou- 

 sand French leagues ; its breadth is, near tlie town of Jenisseisk, more than COO 

 fathoms. Formed on the north of Mongolia, and under the 51° degree of lati. 

 lude, by the union of the rivers Kemtchik and Ouloukem, it first bears the name 

 of Kem, which the fllongolians give it. After its entry into the Russian territo- 

 ry, it constantly directs itself to the north, traversing the government of Jenissei 

 in its whole length, almost in a straight line. Its principal feeding streams to 

 the right are the lofty Toungouska, Toungouska beyond the rocks, and inferior 

 Toungouska ; to the left Abakan and Touroukhan. Its course is rapid, especially 

 towards the middle, where it forms also several islands and many cataracts. It 

 throws itself, after having formed a long bay with dispersed islands, into the Icy 

 Ocean, at the northern extremity of the country of the Samoiedes. 



The Anabara follows the same direction from south to north, so as to consti- 

 tute the limit between the government of Jenisseisk and the province of Jakoutsk, 

 after having watered, in a course of 120 leagues, inhabited countries, it throws it- 

 self into the Icy Sea. 



The Jena takes its origin to the north-west of Lake Baikal, in the government 

 of Irkoutsk. Its course is about 760 leagues in length, after having received, to 

 the right, the Kirenga, the Vitim, and the Aldana, which by itself is very consi- 

 derable, and to the left the Viloui, it empties itself into the Icy Ocean. 



The Jana is formed by the pouring out of a little lake in the country of the 

 Jakoutes, situated at a very little distance from the Aldana, and, after a course 

 of 200 leagues, during which it receives a great number of rivers, it empties it- 

 self into the Icy Ocean by five diflferent mouths. 



The Indiguirka, also called Zapaia Kolyma, is a large river of the province of 

 Jakoutsk, which originates in the mountains in the environs of the point where 

 the Aldana turns to unite itself with the Lena towards the west. It courses 

 for a distance of 300 leagues, is joined by several rivers, and finally divides itself 

 into four arms to enter the Icy Ocean. 



The Kolyma arises from the mountains of the environs of Okhotsk, towards 

 the Eastern Ocean. After a course of nearly 400 leagues, it also empties itself 

 into the Icy Ocean. 



To the east a great number of rivers empty themselves into the gulfs of Pen- 

 gina, of Kamtschatka, and of Okhotsk, but all of them of inconsiderable size ; and, 

 with the exception of the Anadyr, scarcely deserve to be mentioned. This river 

 issues from Lake Joanka, situated in the mountains named Jablonnoi, and flows 

 almost under the Pole. After having followed for some time, in the country of 

 the Tchouktchis, a southerly direction, it turns to the north-east, and empties it- 

 self, after a pretty long course, into the Kamtchatdale Mediterranean, a little be- 

 low the straits of Behring. 



The Terek also flows from west to east, but discharges itself into the Caspian 

 Sea. It is a rapid torrent, fed by the snows of Caucasus, and separates the inde- 

 pendent tribes of Lesghistan from the Caucasian government. It flows under 

 the 44° of latitude.

The American papers contain an oflScial notice in regard to the Tortugas, a 

 cluster of petty islands, or rather shoals, not far from the south point of Florida. 

 Their wliole length is about ten miles. Their surface is in general covered with 

 bushes, but, being low and without any prominent feature, cannot at present be 

 discerned at a greater distance than ten miles. On this spot, which is within the 

 tarritory of the United States, Government have it in contemplation to establish 

 a naval depot, which would give security to merchantmen engaged in the West 

 India trade, and a retreat for invalids in the sickly season. It would also over- 

 awe the pirates who issue from the adjacent harbours.
