principles. The excessive drought ifi f/Qp 
convinced Count Sivers, then chief of this 
department, of the utility of this work, the 
reservoirs of Vyshney Voloshoh being totally 
drained: he procured an order from the Sove- 
reign for the purpose; and the canal, now 
called the Mariemky, was begun to be dug 
between the Knfgia and Vitegra. The first, 
excepting a few places which require being 
cleared a little, is at all seasons pretty navigable, 
and a canal of about six versts is to unite it with 
the Vitegra. This canal is to be supplied with 
water from the Malco Lake (Malcosero), through 
which it takes its course; and the reservoir is 
to have an additional supply by a Cut from the 
great Kofgia Lake. This canal is to be fur- 
nished with twelve sluices, seven of which are 
to serve for the convoy of vessels from the 
Ko/gia, up to the point of separation in the Malco 
Lake: the other five, to conduct them down to the 
Vitegra. This river requires infinitely more 
labour than the Kofgia, to be made navigable ; 
considerable falls require nineteen sluices, to 
make a safe passage practicable; and in some 
places, the digging of circuitous passages, to 
shun the Falls, is absolutely necessary ; extend- 
ing in all to about eight hundred fathoms (of 
seven feet English). The whole space requiring 
labour, the canal included, comprehends seven-
