cess the green ash may be substituted. Some of the best shelter 

 belts on the station grounds are made up of elm, white ash and soft 

 maple for the inside rows, leaving out the box elder, which is apt 

 to make a poor growth after the first few years, except on very deep 

 moist soil. 



For the first few years the windbreak will need to be kept 

 well cultivated. When the trees begin to reach across the spaces 

 between the rows, a heavy mulch of old straw may be applied 

 to the ground to take the place of cultivation. By the time that is 

 gone the trees will have the weed question settled for good. Trees 

 in a wind-break should not be trimmed but allowed to branch 

 freely, clear to the ground if they will. To encourage this the trees 

 are planted further apart than they should be in a grove. 



LOCATION OF THE WIND-BREAK. 



The location of the wind-break will depend upon the conditions 

 surrounding each place. It is a mistake to plant too close to the 

 buildings. Enclose a space large enough to include the garden 

 and fruit plantation as well as to give a spacious yard about the 

 buildings for planting ornamental things. 



Wind-breaks should be so placed that the snow which accu- 

 mulates on the south side in the winter will not cause inconven- 

 ience. If there is some difficulty in doing this a single line o-f 

 willows planted a few rods to the north of the shelter belt will 

 catch the snow and prevent its drifting through. The space 

 between this row and the wind-break may be used for strawberries 

 and bush fruits which are benefitted by a snow protection in 

 winter. Apple and plum trees so located would be broken down 

 by the snows. Where the shelter belt bounds the lot on which the 

 house stands either at the sides or rear or both, it may be greatly 

 improved in appearance by planting more or less irregular masses 

 of shrubbery against it. These break up the rather formal and 

 harsh appearance of the straight lines of trees into something 

 more artistic and effective. As the trees get large a place without 

 shrubbery looks desolate and cheerless compared with the comfort- 

 ing and homelike appearance that shrubs give. 



The shrubs suited for this purpose will be given in another 

 part of the bulletin. 



TREE PLANTING FOR GROVES. 



The primary purpose in planting a grove is to establish a 

 wood lot on which to draw for supplies of fuel and posts as they
