EVERGREEN WINDBREAKS 
AND HEDGES 
A good solid evergreen windbreak about a farm home 
is one of the best investments you can make. It stops the 
cold and the snow, and makes the farmstead comfortable 
and attractive and pleasant to live and work in. Evergreen 
Windbreaks are a permanent investment that grows in 
value every year. 
Plant windbreaks in a double row 12 to 15 ft. between 
the rows, and 4 to 5 ft. apart in the row. Plant Arbor- 
Vitae hedging 18 inches apart. 
BLACK WALNUT. Grown from native seed. 
This adds pleasing variety to the shelter-belt plant¬ 
ing. The nuts are valued for eating and in cookery. 
RUSSIAN OLIVE. Ours is the true hardy 
Mennonite Strain which stands the extremes of cold 
and drought of the western plains country in Da¬ 
kota. Fast grower adapted to dry locations. 
LAUREL LEAF WILLOW. Is the tree for wet 
soils where many other trees do not thrive.
