 ment, continued for some time, had an obvious effect in 

 retarding the growth of the plant. However, other readings 

 taken in culms which were only used once or twice quite agree 

 with the general result of the observations, so that this may

 such drastic treatment as the above would no doubt injure the 

 growing part so much as to render all results useless, but the 

 growing region of the culms of Dendrocalamus is so large thai 

 the growth was not perceptibly affected unless repeated in- 

 cisions were made. The following tables are typical of the 

 general results obtained: —
