the windward margin of the belt. A line 

 drawn from the tops of the tall sentinels 

 on the outskirts of the plantation to the 

 tops of the trees on the inner margin, and 

 touching the tops of the trees of each suc- 

 cessive row, should form a downward 

 curve. A good arrangement where the 

 snowbreak is to be about two rods wide is 

 as follows : 



and fifth rows should be planted with the 

 common Wild Plum. 



The railway companies of the northwest 

 could save enormous investments in snow 

 fences if they would plant snowbreaks 

 along the north sides of their rights of

MAP OK A PROPOSED PLANTATION SUITABLE FOR THE DAKOTAS, PROTECTED FROM THE 

 PREVAILING NORTH AND WEST WINDS BY A SNOWBREAK. 



A single row of some stately species 

 such as Bull or White Pine should be 

 planted on the windward side of the belt.

 third row should consist of Russian Wild 

 Olive or Choke Cherry, and the fourth

 Prof. N. E. Hansen, of the South Dakota 

 Agricultural College, that the Russian 

 Government is planting trees and shrubs 

 for snowbreaks on a laree scale alonsr the 

 the imperial railways in Siberia.
