in their permanent sites the spring following the planting of seed 

 in the nursery. 



PLANTING. 



Since the locust has a wide-spreading root system, it requires 

 plenty of room for the proper development of the tree. A spacing of 

 4 feet apart each way in the permanent site is too close unless very 

 early thinnings can be made and the material utilized for stakes. 

 In the East the trees should be set at least 6 feet apart each way. 

 In the Middle West they should be spaced 4 feet apart in rows 6 feet 

 from each other, or 3 feet apart in rows with 8 feet between. De- 

 tailed directions for planting forest trees are given in Forest Service 

 Circular 61, which will gladly be sent free upon application to the 

 Forester. 



Locust does well in pure stands, but in the semiarid region of the 

 Middle West, where forest plantations are valued also as wind-breaks, 

 it may be mixed with Russian mulberry, Osage orange, or green ash. 



CULTIVATION AND CARE. 



In the Middle West careful preparation of the soil and cultivation 

 for several years after planting are essential for successful growing 

 of the locust. To secure a stem that will make straight posts, poorly 

 formed or double-headed trees may be pruned or cut back to the 

 ground two or three years after planting. 



The plantation should be kept absolutely free from the presence of 

 live stock, and carefully guarded to prevent fire from running over 

 the ground.
