VOLUME ALLOTMENT 149 



Plan of Utilization : All stands over sixty years old are ripe, 

 and also all defective, and broken stands, and those with a current 

 growth in value of less than 3%. All thinnings are lumped at 300 

 cubic feet per acre for each thinning, these to come twice in every 

 period, i. e., every ten years, so that each acre is credited with 600 

 cubic feet, of thinnings, for each period but none during the period 

 in which the stand is planted. 



c. From the above Plan it appears that the first Period (1914- 

 1933) is deficient in ripe stuff, that the forest is quite irregular, that 

 Age Class II is unduly represented. As in the case of AVea Allot- 

 ment, there is considerable shifting of stands from the second into 

 the first period column. All defective, broken stands such as those 

 of lots five and eight- are assigned to the cut of the next twenty years. 

 In this way easily eight million cubic feet can be assigned to Period 

 one, with the expectation that in 1934 a re-shifting of part of what 

 is now Period No, 3, into Period No. 2 will take place. 



d. In the above plan the Cut of eighteen million cubic feet is 

 definitely located through selection of ripe stands. But the forester 

 has abundance of choice, as to the stands to be cut the first, second, 

 etc., year. If at any time during the twenty years, or the life of 

 this plan one stand appears more in need of removal than another 

 there is nothing to hinder the forester. In this way every stand can 

 receive attention and all timber cutting may be decided by financial 

 or other considerations, provided always that the forest is in right 

 condition, is* properly divided into lots and Cutting Series, and 

 receives proper care in silviculture. Since the timber alloted to the 

 next twenty years' cut is not all cut in one year, but in twenty years, 

 there is quite an appreciable amount of growth on this timber. This 

 growth is usually added as a lump sum, it being assumed that the 

 whole mass grows for one-half of twenty years as an average. So 

 if twenty million feet are assigned and they may be assumed to grow 

 at 2%, the total mass is 20 (i.O2 10 )= 1.22 (20) =24.4 million feet. 



e. The Method of Volume Allotment as outlined above re- 

 sembles Area Allotment. If well done, and properly revised every 

 twenty years there is no reason why this plan should not work for
