of the native pines produce equal or superior wood, reach a larger size, 

 continue their growth for a longer period, and, with some experience, 

 can be handled as successfully. It may, however, be advisable to con- 

 tinue the planting of it until we understand the silvical requirements 

 and preferences of the native pines better, especially upon sites with 

 adverse growth conditions, such as extremely sandy areas and wind- 

 swept slopes and plateaus, upon which this soil-modest and windfirm 

 species is known to grow satisfactorily. It may also be recommended 

 for planting upon areas occupied by scrub oak and other inferior for- 

 est growth, for its aggressive habit during youth fits it particularly to 

 overcome this type of almost worthless growth, which is very common 

 and covers extensive areas in Pennsylvania.

An "old practitioner" enlarges on the French 

 French forests which have not been within the war zone, 



Forest but have been cut for war materials and which, 



Recuperation in spite of faulty exploitation, may recover in 

 a short time. Admitting such faulty treatment 

 that could have been avoided, the author goes so far as to claim that the 

 abandonment of the spirit of economy, which was charged against the 

 forest service before the war, has been in some cases a benefit, by open- 

 ing middle-aged stands of oak and beech mixed, which should have been 

 thinned to favor the oak and to give light for its regeneration, so that 

 to satisfy the army requirements has often meant only anticipation of 

 the regular cut. But thieveries of fuel wood have done much damage 

 in the coppice stands, while, on the other hand, poaching and illegal 

 hunting by the military has reduced game so as to diminish sensibly the 

 damage it is responsible for. 



In the pineries it is different. Here clear cutting has been practiced 

 in larger or smaller fellings, and natural regeneration is not to be re- 

 lied upon. Here, as before, replanting becomes necessary. In this 

 case, too, the reduction of game has been an advantage. In this re- 

 planting the author admits for conifers only Scotch and Maritime pine, 

 to be grown in "flying" nurseries, which require the least attention and 

 cost. 



Planting stock of birch (white) can be secured directly from the 

 forest. Of other broadleaf species the author favors the chestnut, 

 wherever climate and soil are satisfactory, and oak. Ix^th of which he
