stand might be cut to advantage, leaving an even-aged stand of pine, 

 but it would probably be better to leave them as standards to supply 

 some extra-large material in the final cutting of the planted stand. 



The result of following either of the two plans of cutting in this 

 stand appears in the following table :

As to the products of cutting, the same limitations apply that 

 were considered under the plan of clear cutting in one operation. 

 They should be, as far as possible, what the owner requires and 

 the balance put into cordwood. If the products of the first cutting 

 were all cordwood, there would be about 12 or 13 cords per acre of 

 good merchantable wood. 



It is believed that with the small white pine already present and 

 the planting provided for above, no additional planting would be 

 necessary to replace trees which may die or which may be destroyed 

 in the second cutting. 



The cost of the first cutting will be about $20 per acre and of 

 the second cutting about $25 per acre. The planting suggested, in- 

 cluding stock, will cost about $6 per acre. The biennial cleanings 

 after the first and second cuttings will each require five or six hours' 

 labor per acre of a careful man. The cost will, of course, depend 

 upon local conditions. The result will be the same as would be ob- 

 tained by clear cutting in one operation — a stand of young pine on 

 good soil, which, if fires are excluded, should grow rapidly and yield 

 a greater quantity of wood of higher value than the stand which it
