PLANTING PLAN FOR PRAIRIE FARMS. 31 



wide and is composeckof black locust and white elm in alternating 

 rows 8 feel apart. The trees arc 4 feet apart in the rows. 



(4) South and west of the orchard site a windbreak was planted 

 composed of two rows of Eussian mulberry on the side nexl the 

 orchard and two rows of white elm on the outer side. These rows 

 are 8 feet apart and the trees 3 feet apart in the rows. 



(5) Beginning somewhat east of the draw, the windbreak south 

 of the orchard Avas extended to the eastern boundary by planting 

 black locust and white elm as in No. 3. 



(G) West of the residence site a block 150 feet square was planted 

 according to diagram 8, to serve as a shelter for the house.

(7) Cottonwoods were planted at intervals of about 8 feet around 

 each pond formed by the dams in the draw. 



(8) Along the south side, next the road, along the southern half 

 of the western side, and outside the windbreak west of the orchard, 

 hedges of Osage orange were planted, each consisting of a single row 

 of plants set 1 foot apart. 



The interval between most of the rows in these plantations is made 

 8 feet to permit of repeated tillage. Where rainfall is deficient the 

 soil moisture can be conserved in that way. When the trees in these 

 plantations are mature they will thoroughly protect the whole farm 

 from the hot southwest winds. 



In this plan a rather unusual number of tree species are provided 

 for. All are suitable for the situation, however, and have valuable 

 qualities. Hackberry, wild china, and western yellow pine probably 

 will succeed also in many parts of this belt.
