over the Cataracts; from this river the vessels 
were to go up the rivulet Sckerevia, by help of 
sluices, to the village Voloka, whence a canal of 
five versts was to be made to the Lake Voloshkoe, 
which was to form the point of separation. 
From this lake issues the River Voloshha, 
emptying itself into the Keni Lake, which gives 
birth to a considerable river of the same name, 
falling into the Onega River, down which the 
navigation was to proceed, to the antient wharf 
of the Novogorodians, at the village Markomonsa; 
thence, by a canal of five or six versts, to the 
River Yamtsa, through which, by the help of 
sluices, to pass into the Northern Dvina. On a 
new survey, in 1 800 , it appeared that not only 
enormous sums were requisite to make the 
Cataracts of the Podia passable, but doubts 
were entertained, whether the proposed point 
of separation, at the Lake p r oloshkoe, could 
furnish the necessary water: but the chief 
obstacle was found to be from the respective si- 
tuations of the rivers Yamtsa and Onega, the latter 
having an elevation above the former, of 1 1 7 m 
the extent of 100 fathoms (7 00 feet Eng.), where 
it is impossible to dig, or make use of a canal 
by any known means. The Yamtsa could never 
furnish a sufficiency of water, even were a canal 
dug, of three or four versts long, and thirty 
feet deep, at a great expense, through some
