case, the selection must be made from the hardier 

 species of pines. 



•Where a piece of unoccupied ground can not be 

 allotted as space for a regular and formal pinetum, 

 constructed on scientific principles, a considerable col- 

 lection of pines may be formed in the woods, in which 

 much scenic beauty may be displayed, and all the 

 interest arising from individual specimens may be pre- 

 served. This plan can be most easily and successfully 

 executed when the trees, already planted, have not 

 attained a greater age than twenty or thirty years. 

 "When the woods are older, much wider spaces must 

 be cleared out. In either case, however, a sufficient 

 number of the old trees must be removed to allow to 

 the new groups or individual plants a suitable breadth 

 of air and light from above. When this is not attended 

 to, the young trees will be excessively drawn up, and 

 so lose their natural characters. For the same reason, 

 the old trees should be early, but gradually thinned 

 out, in order that the pines may be inured to the cli- 

 mate of their position. To insure success, the ground 

 should be trenched, to prepare it for the reception of 

 the plants, and to cut oif the roots of such of the old 

 trees as are likely to interfere with the new comers. 

 A little fresh soil, also, employed in planting, will be 

 advantageous. If large pits are opened and filled up 

 with new soil, the directions given above must be fol- 

 lowed. We are disposed to think that a pinetum in 

 the woods, when well executed, is one of the most pro- 

 pitious arrangements for the growth of the young 

 pines, and among the most graceful in point of scenic 

 character that can be formed.
