called Monsha, the other Lavenna. Both 
branches have falls and rapids, but are 
capable of improvement, particularly the 
Lavenna, and might be easily made navi- 
gable : the last is to be joined with the River 
Niemen, by means of a canal of ten versts, 
and the River Nevegia. By this new water 
conveyance, articles of trade, and necessaries 
of life, may be directly carried to Riga from 
the fruitful provinces of Poland, instead of 
being, as now is the case, transported to 
Merriel and Konigsburg, and there sold at low 
prices: of which more hereafter, when the 
River Niemen is treated of. The navigation 
of the Bludera deserves even now some at- 
tention, in consideration of the timber floated 
down to Riga for exportation. 
The Yavghel, two branches of the same name, 
unite with the lake so called, which empties 
itself, by a large natural canal, ( Stin-sea , or 
lake), near the estuary of the Dvina. Another 
small river joins the Stin-sea with the Verga- 
sea, which could be united with the River Aa 
by a canal of some few versts : by this a new 
water conveyance would be opened with the 
Lake Peypus, and the government of Pshof. 
Some articles, such as provisions, charcoal, 
wood for fuel, See. are carried to Riga, by 
this river.
