author concludes that P. Hexilis has reached its climatic limit on 

 the ridges, being prevented from farther advance by dry winter 

 winds, but that P. Engelmanni on the wet meadows is ascending 

 to altitudes higher than its present limits.

Dr. Martin continues his valuable critical 



Forest review of forestry practices in various coim- 



Practices tries on the basis of personal observation, 



in France. France being the latest object of discussion. 



The statistics are briefly as follows. The 



total forest area occupies only 16%, the departments of Landes 



with 47%, Var with 42%, and Vosges with 35% being the most 



heavily wooded. 



The State owns 2.5 million acres or 11%; municipal and other 

 public corporations 23% ; leaving 66% for private ownership. 

 The latter is absolutely free of state control, the organic forest 

 code of 1827 being silent on this point, except only on areas de- 

 clared as protective forest, where clearing is forbidden. Corpor- 

 ation forests are administered by the State. 



The management of State forests is extremely conservative, 

 large accumulation of old stock and high rotations are character- 

 istic, while the corporation forests are managed much more ex- 

 tensively. 



This appears in the distribution of systems of management. In 

 the State forests 40% are timber forest, 26% composite, 1% 

 coppice, 9% under conversion from the latter to timber forest, the 

 balance protective forest, except about 14% still without working 

 plans. Of corporation forests only 20% are timber forest, 10% 

 coppice, 3% protection forest, the balance composite, except about 

 15% which is still without system. While in the State forest 

 about 15% of the timber forest is under selection system, in the 

 corporation forest nearly 60% is under that system. Private 

 forest appears to be mostly in coppice or composite forest. (Ap- 

 parently, therefore, of the total of 23 million acres, only about 

 2 million acres are timber forest — a poor showing!) 



The most prominent species in State and corporation forest is 

 the oak with 29% of the area, beech follows on 19%, blue beech 

 on 16%. Conifers are poorly represented; fir occupies 7%, es-
