and from bark beetles, but the author thinks by proper treatment these 

 can be avoided, especially by timely thinnings, and, in the nursery, by 

 wide spacing of transplants, etc. 



In conclusion, while the author wants the fir to remain the leading 

 species in the Vosges Mountains, the spruce is to be introduced in the 

 larger openings whose soil is somewhat deteriorated.

A report by Milward, of the Indian Forest 

 Artificial Service, on teak management in Java is of inter- 



vs. est to us mainly for the discvission on methods of 



Natural propagation. It appears that the proper silvi- 



Regeneration culture of this most important Indian tree species 

 "to the Indian forester still continues to be the 

 question of questions and as far from finality as ever before." In 

 British India there are at least four distinct methods used : that of 

 plantation, pure and simple ; the taungya system, in combination with 

 farm use and gradual planting by annual addition of saplings ; natural 

 reproduction, which "involves an enormous expenditure of labor and 

 money, but the results are often of merely temporary benefit, thus pro- 

 ducing a minimum effect with a maximum outlay" ; lastly, coppicing. 

 The Dutch Government have almost from the very outset come to 

 the definite conclusion that the management of natural teak forests is 

 not only difficult and expensive, but is on the whole uncertain ; they 

 have, therefore, substituted a wholesale system of planting, some 84,000 

 acres having been planted in Java. Interplanting with leguminous crop 

 (Leucccna glauca), which keeps weeds down and enriches the soil, is 

 also practiced.
