216 LANDSCAPE-GARDENING 



north from the honey locusts are other trees forming 

 almost an arboretum. These include all the oaks 

 found growing along the rivers or in those wooded 

 areas which exist in nearly all the prairie states. 

 There are many species of oaks, several species of 

 maples, black walnuts, hickories, ash trees, butter- 

 nuts, lindens, elms, wild cherries, buckeyes and 

 hackberries. With these trees are scattering haw-

 and Carolina roses. Many native and some intro- 

 duced flowers persist in growing along the roadside.

 inforced by wood-lots on either side similar to the 

 one already mentioned. The trees standing between 

 the path and the roadway, that is, occupying a strip 

 lying between six and eighteen feet from the fence, 

 will more than repay by their beauty, shade and 

 protection from wind any harm they may do to the 

 crops in the adjoining fields. These trees as well as 

 the lower growth will furnish places for birds' nests, 

 while the berries and other fruits will serve as dessert
