Plavio, the source of the Rivulet Cergontza 
which falls into the Beresen, and the Lake 
Bereshta, the source of another rivulet of the 
same name, which fells into the River Yessa, 
ten versts above Leppel. For this purpose it 
was necessary to dig a canal of eight versts, 
with four sluices, and to make circuitous 
cuts in some parts of the Rivers Cerguza and 
Bereshlh, the first of seven versts, and three 
sluices ; and on the Bereshte, two versts, and 
two sluices. On the Onlla itself it is neces- 
sary to build four sluices, and clean the bed 
of the river: all this is begun; and in 1805, 
it is supposed, it will be completed. By this 
track, a water communication will be opened 
between the Black Sea and the Baltic; and 
the conveyance of the products, not only of 
the province of Minsk, but of White and Little 
Russia, and the Polish Ukraine, to Riga, will 
be facilitated. Another plan was proposed, 
to unite the above-mentioned seas, by means 
of the Upper Dvina (Duna), in the neighbour- 
hood of the town Babinovitzey , with the Upper 
Dnieper; but, independent of the extraor- 
dinary labour, it appeared that there was 
an insufficiency of water. 
The Oiiole. Some wood and provisions are 
conveyed down this river in spring, during 
high water.
