The tables bring out the fact that the spacing, more than any 

 other factor, influences the acre cost of planting. The spacing of 

 4 by 4 feet requires so many trees per acre that, as a rule, its cost 

 is prohibitive. The 6 by 6 plantation will vary in cost between $6 

 and $13 per acre, although when all incidental expenses of planting 

 are figured it may in some cases exceed $15. A spacing of 8 by 8 

 feet is very desirable from the standpoint of cost, and on good soils 

 with cool, moist exposure, the rapid growth of the trees may fully 

 warrant it. In such cases the first thinning may be made later than 

 with other spacings. While with the wide spacing the branches may 

 grow a trifle larger, they will persist no more tenaciously than when 

 the stand is denser. The saving in the initial cost may be later 

 expended to good advantage in pruning. Moreover, in a widely 

 spaced plantation there is room for the development of desirable 

 broadleaf trees between the pines. 



DIRECT SEEDING. 



Under average conditions artificial sowing is less likely to be suc- 

 cessful than planting, and hi a number of cases has resulted in com- 

 plete failure. There are, of course, notable exceptions, such as the 

 Shaker plantation in north central Connecticut, where a very dense 

 forest resulted from the broadcast sowing of pine seed along with
