Th e following lists are at best generalizations and as such are to be 

 used with extreme caution. A statement of fact in one locality may be entirely 

 without weight in another community. In using the appended tables, the planter 

 must compare the data given with actual results as shown by the trees in his 

 neighborhood. It is impossible to give lists which will hold for all parts of 

 this state. We have here considerable sectional variation in soil, temperature 

 and moisture conditions, as well as variations within the section. This latter 

 may be noted especially in soil and moisture, even in the length of a single 

 street in some districts. 



Do not therefore, accept the lists as final. Use them as a starting point 

 and modify as your conditions must demand. A few points may be useful as 

 guides in original work. 



1. If your summer temperature is high and hunidity low, do not use 

 meny deciduous trees of Eastern origin. Do not use conifers, 

 with few exceptions, as the dust conditions are particularly 

 trying to them. 



2. If the water supply is slight (i.e. the natural supply after 

 trees are established), if this is slight, do not select 

 species needing abundant soil moisture. 



3. If there is alkali, use trees which will tolerate such amounts 

 ate may be present. 



4. Select trees which will harmonize with native vegetation. Do 

 not plant species characteristic of arid regions in the semi- 

 humid parts of the state and do not plant trees characteristic 

 of humid regions in the arid portions of the State. While all 

 street work must be artificial to a slight degree, there is a 

 certain fitness of things which is essential.
