330 Forestry Quarterly 



The same conditions were observed in beech sections, showing 

 from 10 to 13 times the increment after interlucation, with one or 

 two years non-response between. By looking over stumps, it 

 was found that the response continued at least for 15 and 16 

 years on 80- to 100-year trees, and appearances promised a longer 

 continuance of such response. This response was also shown 

 in the upper sections, although the width of the annual rings 

 in the upper sections was relatively smaller than those of lower 

 sections (increased taper!). 



The greater reaction at the base, the author explains as due to 

 reaction to wind. 



As to the undesirable quality of this uneven-grained wood, 

 the author states, that these examples are extremes showing the 

 reaction of suppressed trees, chosen to bring out the fact of the 

 reaction strikingly, but that, if normally developed trees were 

 taken, the quality defect would be lessened or would vanish 

 altogether.

Dr. Martin, in continuation of his discus- 



Practical sion on Swiss conditions, elaborates on the 



Application practical considerations in the application of 



of silvicultural methods of natural regenera- 



Regeneration tion, and especially the direction of the 



Methods progress of fellings, the importance of 



which Wagner, with his strip-selection 



method, has lately so much accentuated. 



In Switzerland, rules in this and other respects are often 

 noticeable by their absence, and success is secured in spite of 

 their neglect, as e. g., in the forests of Winterthur, where excellent 

 regeneration is secured with a progress of fellings from south- 

 east to northwest, while Meister in Zurich regenerates one half 

 his forest from north to south, the other from south to north 

 with equal success. The direction of valleys and aspect of slopes, 

 to be sure, influence the direction of fellings, and these in Switzer- 

 land being very varied, general rules cannot be given ; moreover, 

 climatic conditions are so favorable that almost any method suc- 

 ceeds.
