Plate 26. It is when snow comes that we most appreciate the green 

 foliage and cheerful beauty of evergreens. The above cut shows Jack pine 

 (at left), Norway spruce (center), and Scotch pine (back of center), in winter 

 condition at the South Dakota Experiment Station. 



Summary. 



1. With proper care as to methods and varieties, South 

 Dakota planters can grow evergreens with success upon our 

 most exposed prairies. 



2. Some of our hardiest and best native American ever- 

 greens have been greatly neglected for European varieties 

 less desirable for prairie conditions. Special attention is 

 directed to the native South Dakota evergreens. 



3. Hardiness means ability to resist not only cold, but 

 heat, windsweep and all other factors of climate. Much 

 depends on the original source of the seed. Attempting to 

 acclimate a mild climate evergreen to northwestern prairies 

 is useless, as acclimation is a work that nature takes thous- 

 ands of years to complete. It is best to take advantage of 

 nature's work by selecting varieties already adapted to 

 prairie conditions.
