A very rich iron ore in veins was here difeovered hi 
ne year 1749, on a deep, woody mountain, about ten 
nglifli miles from the river Jenifei, and 1 So miles from 
the town of Krafnojarfk, fituated on that river to the 
\ out ward, about 54 0 of latitude, between two rivulets 
known by the names of Ubei and Sifim, and running 
into the river on the Eadern fide. This place was then 
vilned by the Ruffian miners; but as there was plenty 
o iron ores fituated much nearer to the Fabricks the 
mine never was worked, though the ore contains above 
icventy pounds of iron in the hundred weight, beine of a 
dark deel colour, turning red when rubbed, and income 
parts endowed with a magnetic virtue. Upon the fame 
mountain, where this mine is fituated, on the North-fide 
much below the top of the mountain, the mafs of native 
iron lay on the very ridge, without being fixed to the 
r ock, which is a grey, dratified faxum. There was, on 
that and the neighbouring mountains, no trace of ancient ' 
miners and their kilns, which are found in many other
