Advantage of the Six-Foot Spacing. The close spacing 

 is intended to kill off the lower branches as the trees grow, to 

 shade out other vegetation and to produce tall, straight and 

 clear timber. Trees planted six feet apart will require thin- 

 ning at the end of fifteen or twenty years, and a second 

 thinning, on which some profit will be realized, can be made 

 in thirty years. On short-time crops, such as posts, the thin- 

 ning is not so important, as the trees will enter the crowding 

 stage just at the time when they are ready for use. If planted 

 trees are left too long a time without thinning they will thin 

 themselves in the natural way bv killing each other off. 



Underplanting. If there is already a thin stand of trees 

 on the land, plantings can be made in the open spaces. The 

 trees already present will force the transplants to 'seek light 

 and they will grow more tall and straight as a result of this 

 pressure. Where there is overhead shade spruce and hemlock 

 should be used. Where the shade is too dense underplanting 

 is not advisable.

Care of the Plantation 



No cultivation is given a forest plantation as a rule, 

 because the land is unimproved. The plantation must be pro- 

 tected from fire, and stock must be kept out at all times. As 

 the trees grow they will meet with opposition from several 

 sources, and these will be described in our leaflet on Forest 

 Protection. 



Results 



We now come to the final and practical question, "What 

 do we get?" Large numbers of bulletins have been written by 

 government and State experts, by technical men in the colleges, 

 and by foresters in the field in answer to this question. 



If you have planted for a long-time crop, you will get, on 

 average soil, at least twelve thousand feet of pine in thirty 

 years, and just four times that amount in fifty years, or 

 approximately fifty thousand board feet per acre. The poorest 

 soil will give you forty thousand feet per acre in fifty years 

 in addition to the thinnings previously made for the purpose 

 of removing the crowded trees. If hardwoods are planted in 

 the mixture, these can be cut at intervals after the fifteenth 

 year, leaving the pine as the ultimate crop. 



If your planting has been done with the short-time crop in 

 view, your returns will be found among the following: 



(1) A crop of fence posts every ten years, four posts to 

 the tree, at a return of about $70 per acre per year. 



(2) A crop of pulpwood, box board or excelsior stock in 

 fifteen years or less, followed by a similar crop every eight or 

 ten years thereafter, the largest trees being taken at each 

 thinning.
