White See also:Sea, and is formed by the junction of the Sukhona and the Yug, which, rising, the former in the See also:south-See also:west and the latter in the south-See also:east of the See also:government of See also:Vologda, meet in the neighbourhood of Velikiy-Ustyug, at a height of 300 ft. above the sea, in 61° 20' N. and 46° 20' E
.
The conjoint stream then flows N.W. to the Gulf of See also:Archangel, which it reaches 50 M. below the See also:city of Archangel
.
From its mouth to the confluence of the co-tributary streams the distance is about 470 m., and to the source of the Sukhona 78o m
.
The drainage See also:area is estimated at 141,000 sq. m
.
Except at the rapids the current of the Dvina is comparatively slow, as the See also:average fall per mile is only 9 in
.
Till its See also:union with the Vychegda, a See also:river which exceeds it in See also:volume, it flows for the most See also:part in a single, well-defined and permanent channel; but below that point it often splits into several branches, and not infrequently alters its course
.
In the neighbourhood of Archangel it divides into three distinct arms, which See also:form a See also:regular See also:delta; but of these that of See also:Berezov alone is navigable for sea-going vessels, and even it is impeded by a See also:bar at the mouth, with not more than 141 or 152 ft. of See also:water at full See also:tide
.
Just above the point where the delta begins the river is joined by a large tributary, the Pinega, from the right
.
Above the confluence of the Vychegda the breadth is about 1750 ft.; below that point it widens out to 3500 ft.; and near Archangel it attains more than three times that measure
.
The channel is See also:free from See also:ice for about 174 days in the See also:year
.
By means of the See also:Duke See also:Alexander of See also:Wurttemberg See also:Canal, the river is connected with the See also:Neva and the See also:Volga

The See also:SOUTHERN DVINA, or Dvina Zapadnaya, in See also:German See also:Dana and in Lettish Daugava, belongs to. the Baltic basin, and takes its rise in a small See also:lake about 800 ft. above the level of the sea, in the government of See also:Tver, not far from the See also:sources of the Volga and the See also:Dnieper
.
After dividing Tver in part from See also:Pskov in part, it skirts the east and south of the government of See also:Vitebsk, separates part of the latter from See also:Vilna, and then divides Vitebsk ,and See also:Livonia from Couriand, and disembogues in the southern end of the Gulf of See also:Riga
.
Its length is 64o m. and it drains an area of 32,960 sq. m
.
From See also:Dvinsk (Diinaburg) to Riga, a distance of 135 m., there is altogether a fall of 295 ft., of which 105 ft. are in the 40 M. from Jakobstadt to Friedrichstadt
.
In the See also:lower part of its course the river attains an See also:ordinary See also:depth of 30 ft. and an average breadth of 1400 ft.; but during the See also:spring See also:flood it sometimes rises 14 ft. above its usual level, and its See also:waters spread out to a mile in width
.
Near the mouth the river is . usually free from ice for 245 days in the year, and in the government of Vitebsk for 229
.
It is navigable from the confluence of the Mezha (i.e. from Vitebsk) downwards, but the number of rapids and shallows greatly diminishes its value
.
See also:Navigation can also be carried on by the following tributaries: the Usvyat, Mezha, Kasplya, Ulla, Disna and Bolder-aa
.
This river was formerly called the Khezin or Turunt, and at the See also:present See also:day it has the name of Polot among the White Russians
.
See also:Salmon and lampreys abound in its waters
