Domain Commission are authorized to raise trees for 

 planting and to sell them at nominal cost to coun- 

 ties, cities, villages and citizens of the state for high- 

 way planting and also for planting in state parks and 

 other public places. 



The Forestry Department of the College has at the 

 present time a considerable number of trees suitable 

 for this purpose. 



Mistakes made in the selection of species of trees 

 for highway planting, may not be discovered in a 

 decade. In order to make such mistakes less com- 

 mon and to safeguard the public against errors in 

 spacing of trees and selection of species for our 

 highways, the following simple principles are offered : 



1. Use only such trees as are comparatively free 

 from destroying insects and disaeses. 



This will eliminate at once such trees as the black 

 locust, the elm, the fruit tree, and any others which 

 may have local enemies. 



2. Use trees adapted naturally to the soil and 

 climate of the locality. 



For example, a burr oak section should not have 

 its highways planted with pine nor should a red 

 pine section be planted to burr oaks. 



3. Pure planting of one species should not be 

 used for distances exceeding one mile. 



4. Use trees that are native to the locality wher- 

 ever possible. They give quick results and furnish 

 variety. 



5. Along roads that have been entirely denuded 

 of tree growth, plant a temporary and a permanent 

 tree alternately. An example would be : The sugar
