The Ousiistka. This stream was, by a former 
plan, intended to form the means of commu- 
nication between the Dvina and the Lovata, 
falling into the Lake Ilmen , as a new track 
by water from IFhite Russia. On the execu- 
tion of the plan projected to unite the Dnieper 
and the Southern Dvina about Babinovitzey, 
the conveyance by water may be extended 
even to St. Petersburg, from Little Russia, See.; 
and the same track may open a water com- 
munication between the last-mentioned city 
and Riga : for this purpose it was intended 
to dig a canal along the Oushstka (which is too 
shallow), from its source at the Lake Oushstka ; 
this was to serve as the principal point 
of separation, or common reservoir to the 
River Pola, at the village Vlaslcova, and 
thence to Veliky Lughy ; but it is not decided 
whether the above lake is sufficiently stored 
with water for so extensive a communication : 
at all events, the advantages that are to be 
expected from this project are such as deserve 
the greatest attention and examination, as to 
the practicability of execution, at any expense 
whatsoever.
