large part of southern Minnesota and appears to be better adapted 

 to dry locations, preferring such in its native habitat. 



In planting a row of street trees, it is well to avoid placing them 

 too close together. The tendency to over-plant in a prairie village 

 is well nigh irresistible. The prairies look so large and the trees so 

 small. It is well, I think, to set each alternate tree along the street 

 with some quick growing species. I know of nothing better for 

 this purpose than the Silver Maple (Acer sacharinum, or, as it is 

 called in the old botanical manuals, Acer dasycarpum.) On the 

 prairie lands of western Minnesota this tree is rarely broken by the 

 wind and must be voted a success. When the elms begin to attain 

 size, the maples should be removed. 



Another very successful street tree is the Green Ash. This tree 

 is known to the younger generation of botanists as Fraxinus lance- 

 o.'ata, but is perhaps more commonly called Fraxinus viridis. It is 

 the common native ash tree throughout the prairie portion of the 

 state. The Green Ash does extremely well as a roadside tree 

 wherever planted. 



Another very valuable street tree for the prairie portion of the 

 state is the Hackberry (Celtis occidentalis). This very excellent tree 

 is at home on the prairies. The Hackberry is rather slow in coming 

 into leaf in the spring, but makes up for this by the umbrageous 

 luxuriance of its summer! foliage. Should you fail to get a Hack- 

 berry as a street tree, you can hardly afford to miss having a tree or 

 two in the timber plantations of your home grounds. 



The subject of ornamental tree planting about the house is a very 

 broad and a very difficult one. No two locations present the same 

 problem. To secure the best results each locality must be studied 

 by itself — and it is here that the services of a professional land- 

 scape engineer ought to be secured. If your home is on the prairies, 

 your home ought to front to the south or to the east. You will then 

 want shelter on the north and west. Here you should plant an 

 irregular border of such trees as Scotch Pine (Pinus sylvestris), 

 White Spruce (Picea canadensis). Red Juniper (Juniperus virgin- 

 iana), Bull Pine (Pinus ponderosa). Blue Spruce (Picea pungens) 

 and Mountain Pine (Pinus mughus, or Pinus montana). Here, too, 

 should be located that grandest of all deciduous trees for prairie 

 planting, the Bur Oak (Quercus macrocarpa). 



If from your house you have a view over a river valley or across a 

 lake, or if in any direction there is an interesting sky line, you must 

 study to preserve it, or even to accentuate or improve it, by leaving 

 an irregular vista through your plantations in that direction. If on 

 the other hand there are some disagreeable features in your land- 

 scape, such as a neighbor's untidy barn or pig pen, then you should 

 plant it out by so disposing your groups of trees and shrubs that the 

 objectionable features of the lahdscape will be eliminated by being 

 hidden behind an attractive border. 



It is well to so dispose your tree planting as to leave a lawn of 

 some considerable extent uninterrupted by trees, from which irreg- 

 ular vistas shall lead off through the trees toward the more distant 

 and secluded parts of the grounds.
