 From the above mentioned data, we have prepared the fol- 

 lowing tables, from which one can clearly see that the reserve 

 materials in the barks of roots and stems rapidly decrease with 

 the development of the leaves, and that at the time of cutting, i.e. 

 May 18-28, they reach the minimum. Compare also Plates XIX-
