GROWING TREES AND FRUITS IN DRY AREAS 375 



to the buildings, as they may interfere with future plans 

 about the buildings, and in areas where snow is much 

 liable to drift it will pile up on the buildings and in 

 the yards, having been carried right over the trees, espe- 

 cially in the early stages of their growth. 



The trees best suited for a windbreak should be 

 planted on the outside, with one to two or three rods 

 between them and the trees of the grove, as the snow 

 that lifts over the windbreak will then fall in a consider- 

 able degree before it reaches the trees of the grove. 

 In some instances it is advisable to have two rows of 

 windbreak, trees, with, say, two rods between. In these 

 spaces grasses, clovers, or alfalfa may be grown, but 

 not too close to the trees, the snow that blows into 

 them furnishing a goodly supply of moisture. 



Some fruits may be planted along the rows and in 

 between the trees, with the understanding that later 

 they will be removed, as the shade of the trees will 

 soon make this necessary. Plums and some small fruits 

 may be thus grown. The abiding place, however, for 

 the fruits, is inside of the grove. Though planted simul- 

 taneously with the grove, protection will soon be fur- 

 nished by the windbreak and forest trees in their upward 

 growtji. 



If trees for protection and for orchard uses are to 

 be planted on breaking, the ground should be broken 

 deeply one year in advance of the planting. It should 

 be carefully worked on the summer-fallow plan. The 

 objects sought are, first, the subduing of the sod, and, 

 second, securing a supply of moisture for the subsoil. 

 If the ground has been cropped previously, it should 

 by all means be summer-fallowed before it is planted. 

 At the end of, say, three years from the time of plant- 

 ing, trees planted thus will be quite ahead of those 

 planted out for four years, but on land not thus pre- 

 pared at the outset.
