ried to the place of planting in pails of mud. The holes in which they 

 are to be set should be made with a grub hoe or light spade, the soil 

 pulverized, and in planting the roots should be given their natural posi- 

 tion, the soil firmed around them, and they should be set two or three 

 inches deeper than the surrounding surface. A young forest should 

 have the sides that are exposed to the prevailing winds more densely 

 planted than elsewhere; wind being one of the forest's worst enemies. 

 In planting a small tract of even five acres, there may occasionally be a 

 small piece of ground such as the bottom of a ravine, with soil fertile 

 enough to sustain hardwood trees such as the sugar maple, ash, chest- 

 nut or oak, and if so, such kind of trees had better be planted, both to 

 improve the appearance of the forest and to attract birds. Two men

 seed of pines that were planted by Mr. Webster eighty-six years ago. (Photographed

can work well together. The first digs the hole; the other, following 

 with the young trees, plants the tree. If the job is large, quite a num- 

 ber of men may be employed ; in such case, the two men who started the 

 first row should keep two trees in advance of the men on their right. 

 Two men can plant 1,400 trees in eight hours. 



Pine grows very slowly the first ten years, but afterwards rapidly 

 up to about its eightieth year; after that it wilkgrow for two centuries 

 or more, but too slowly to earn good interest on the capital it repre-
