white and Norway pine and spruce. Too much cannot 

 be said about the value of the walnut tree for planting 

 in southern Minnesota ; this is a beautiful and valuable 

 native tree and should be generally planted. 



It is always advisable to plant only the kinds of trees 

 which are known to do well in the locality. In order 

 to obtain the best effect, groups of trees should be ar- 

 ranged so as to look as natural as possible. Nature 

 never arranges her planting formally. Evergreens in 

 natural groups are particularly beautiful. 



Some schools may have their own nurseries, where 

 trees are grown from seeds which the pupils gather in 

 the fall and winter ; by doing this, even on a very small 

 scale, the school is able to have the best kinds of trees 

 and a large variety on hand at all times for planting 

 purposes. Generally it is best to buy stock from a 

 commercial nursery. If evergreens are desired, the 

 University Forest Experiment Station at Cloquet has 

 on hand more little pine trees, three to five years old, 

 than it is going to be possible for the State to plant this 

 spring; and a limited number of little white and Nor- 

 way pines may be obtained at cost from that source. 

 The Forest Service has for distribution a bulletin ' * Tree 

 Planting for Shelter in Minnesota", which gives a 

 great many helpful suggestions on kinds of trees suit- 

 able for this state, and how to care for them before and 

 after planting.
