APPENDIX, N° II. 
When the plan of making the Mariensky 
Canal was adopted, it was resolved to make the 
River Vitegra more navigable, by digging canals 
round the dangerous place, and erecting nine- 
teen sluices; which work is already in hand. 
The river is navigable from the head of the 
canal to the Lake of Onega, a space of fifty-five 
versts, and into which it empties itself. Only 
about the extent of fifteen versts is necessary to 
be worked on now. 
The following Streams fall into the River Vitegra. 
The Kall, Taeitza, Yand, Bol, Tighisma. 
These inconsiderable streams are of no other 
use but to form an extraordinary reservoir of 
water for supplying the Mariensky Canal, in 
case of need. 
From the River Vitegra the vessels enter 
the Onega, which they navigate sixty versts, to 
the source of the Svir. Although the navigation 
of the Lake of Onega is not so dangerous as that 
of the Ladoga, the passage of barks or floats of 
timber is not practicable. In consequence of a 
proper survey, a track was discovered, which 
admitted of a canal being dug through or across 
the rivulets Megra and Oshta, from the estuary 
of the Vitegra to the source of the Svir, by 
which the navigation of the Onega will be 
avoided, and the return of barks facilitated to
