TREES FOR MIXED PLANTINGS. 53 



Willow or possibly Cottonwood to furnish a quick protection. 

 The rest of the grove should consist of hardy sorts, and may 

 include some of the evergreens and such fruit-bearing trees or 

 shrubs as the Wild Plum, Wild Black Cherry, Russian Mul- 

 berry and Juneberry. These latter furnish food for the birds 

 and may often be a help in supplying the home table. The 

 plan of planting with a view of providing some food for birds 

 is not mere sentiment, for they protect our gardens from many 

 insects, and if we furnish an abundance of Russian Mulberry 

 they will not trespass much on our strawberries or raspberries. 

 It is the author's opinion that in all our prairie planting we 

 should pay more attention to using our native fruits and Rus- 

 sian Mulberry as plants of secondary importance. 



I,ist of Trees for Mixed Plantings. Some suggestions 

 may be found in the following lists, but several other trees might 

 often be used to give a variety or a tasteful display. 



For Porous Moist Soils in Southern Minnesota. White 

 Elm, Black Walnut, Green Ash and Hard Maple in equal quan- 

 tities with a scattering of the fruit plants. The Hackberry may 

 wholly or in part take the place of the White Elm, and the Box- 

 elder the place of the Green Ash. The White Willow, Bass- 

 wood and Soft Maple would also do well in such a location. 

 One of the main kinds might be replaced by the White or Nor- 

 way Spruce, Douglas Fir or White Pine. In fact such land as 

 this will grow any of the trees adapted to this section. 



For High Prairie Soils in Southern Minnesota. Green 

 Ash, Boxelder, White Elm and White Willow in equal quanti- 

 ties, with scattering of fruit plants. Basswood might be used to 

 a limited extent, and White Spruce, Red Cedar, Norway Pine, 

 White Pine or Scotch Pine might be used in the place of one 

 of the main kinds. 



For Moist, Porous Prairie Soils in Northern Minnesota. 

 White Willow, White Elm, Boxelder, Basswood and Green 

 Ash in equal quantities, with a , scattering of fruit plants. In 

 some localities it might be best to use Cottonwood on the out- 

 side of the grove. Hackberry might take the place of part of 

 the White Elm and White Spruce, Arborvitse, Norway Pine, 

 Red Cedar, and some other conifers might be used to a limited 

 extent.
