rich emphasized the necessity of a universal application of control 

 measures — no use to control a pest on one area and not on the adjacent 

 one — but prefers to accomplish this through education of the public 

 rather than forcibly through laws. This can be done through teachers 

 of winter short-courses, through traveling teachers, and through tech- 

 nically and practically trained insect-pest inspectors, who shall keep 

 posted on the development of the science and pass their knowledge on 

 by means of demonstrations and otherwise. There is perhaps not much 

 hope of making the older generation receptive to such educational 

 propaganda, but much can be done with the coming generation, partic- 

 ularly if elementary instruction regarding the principal beneficial and 

 noxious insects can be given in the public schools. Dr. Seitner is 

 pushing the development of a similar scheme in German Austria. He 

 suggests a central office, well furnished with equipment and trained 

 personnel, and State entomologists or traveling inspectors to collect 

 information and statistics and carry on control work.

MENSURATION, FINANCE. AND MANAGEMENT 



According to Walker, "the trend of opinion in 

 Management of Burma has set strongly in favor of converting 

 Teak in our natural teak forests into even-aged woods." 



Burma These reserved forests are maintained for export 



purposes, and the chief argument in favor of 

 even-aged teak stands seems to be based upon the policy of a partial 

 abandonment of the selection system in Europe rather than on local 

 requirements in Burma — hence Walker opposes the change. His argu- 

 ments are 



(1) What is done in Europe is no criterion for Burma. "To aban- 

 don a system (selection) which is in many ways admirably suited to an 

 undeveloped forest on account of a doubtful theory that under another 

 system (shelterwood) a higher degree of regularity of the yield would 

 thereby be insured, seems to me to be the height of absurdity." 



(2) The yield would really be more irregular than with the present 

 selection method, and the conversion would mean difficulty and dis- 

 arrangement, and the revenue would be dangerously reduced.
