for local labor and because (if restrictive rules are enforced) 

 the population will move to forests where there are no restric- 

 tions. The writer concludes that fire protection, first of all, is 

 necessary; that investigation of native taungya methods is nec- 

 essary and that this can only be secured by having a special 

 officer detailed to study the problem without interference of 

 ordinary executive duties. T. S. W., Jr.

Dr. Max Wolf reports in great detail on 



Combating trials to combat the Nun, and comes to the 



the conclusion that it is foolish to continuously 



Nun. spend money in combating this pest, while 



in its ordinary extent of occurrence. Only 



when a mass of development comes, one is not to be surprised

does not exist, hence only curtailment of the regular cut may be 



practiced to reduce the economic damage which would come 



from an overcut forced by the insect damage.

Calipering. diameter is measured is often inconvenient 



for the workmen, and hence, unless very 

 strictly supervised, not realized. Moreover, the author con- 

 tends that for the end result, the total cross section area, it does 

 not matter. The proof is furnished by five caliperings of the 

 same area of i hectar 90-to iio-year beech forest in unusually 

 normal condition. The measurements under I and II were 

 strictly taken from 2 to 2 cm (inch classes) at 1.3 m (d. b. h.), 

 under III at i.i, under IV and V from 4 to 4 cm. (2-inch 

 classes), the first at 1.3 m, the last at i.i m. The results are as 

 follows :
