General Phytogeographic Relations of the Regions Traversed. 



The Abakan Region and Adjacent Steppe Areas. 



The small town of Minusinsk, from where the expedition was started, is situated on 

 the eastern bank of the Yenisei River, in about 92° east longitude, and 54° north 

 latitude. The traveller approaching Minusinsk from the north by the river-ferry from 

 Krasnoyarsk by the Siberian railway, will rather soon observe, in the general charac- 

 ter of the vegetation, when going southwards, a gradually increasing dryness of the 

 climate. The river-banks are at first rather steep and rocky, reaching from 100 to 150 

 m. above the surface of the water. The eastern river-side is markedly higher and steeper 

 than the western, a strange fact, which may be accounted for by the rotation of the earth.
