 FOREST GEOGRAPHY AND DESCRIPTION 



The rest of the world knows Httle about Sibe- 

 The ria, what is really going on there now, and what 



Forests of the final outcome will be as it knows about any 



Siberia other country on this globe. However, a graduate 



Russian forester, Alexander Koroleff, who has 

 spent most of his life in Siberia, and who is now in the United States, 

 tells something about the forests of that unknown country in a recent 

 issue of The Timberman. According to Mr. Koroleff, there are some 

 1,080,000,000 acres of forest land in Siberia proper. Of this immense 

 area about 4 per cent belongs to the Cossacks and the peasants and 96 

 per cent to the Government ( ?) The Government forests are of two 

 classes, "free-use" forests and those under the bureau of forestry; the 

 latter has under its jurisdiction about 44 per cent of the total timbered 

 area of Siberia, or about 440 million acres. About 25 per cent of the 

 commercial forest has been examined and roughly surveyed. The 

 valuable species are pine, larch, kedr ( ?), fir, and spruce. Pine, larch, 

 and kedr form about 44 per cent and spruce and fir about 23 per cent 

 of the commercial forests. In eastern Siberia are excellent hardwoods, 

 such as oak, ash, and walnut. The annual timber production from the 

 Siberian Government forests normally is about 340 million cubic feet. 

 Before the war the annual timber exports amounted to only five million 

 cubic feet. Mr. Koroleff was sent to the United States last year by the 

 Kolchak Government to study American logging and sawmilling 

 methods ; now there is no Kolchak Government, but he is continuing his 

 study. With the return to Siberia of peace and a settled condition of 

 the country there should be an enormous opportunity for American 

 foresters in Siberia, as well as for manufacturers of American logging 

 and sawmill machinery. J. D. G.

SOIL, WATER, AND CLIMATE 



In summarizing the recent work done on soil 



Soil aeration in India, Albert Howard and R. S. Hole 



Aeration point out that only very indirectly has soil aera- 



in India tion been recognized in European agricultural 



literature and that being in connection with the 



importance attached to a proper soil texture. The authors maintain 



that soil texture is really important because of its influence on soil
