(7) Periodicity in rainfall corresponds with periodicity in 

 growth. 



These general relations are very manifest in the chart,* both 

 in the formation of rings and elongation of the axis. In the first 

 case it will be seen that the period of accelerating growth extends 

 over the first eleven years, and at the end of that time does not 

 appear to Le fully completed. In the second case, the period of 

 diminishing growth is found to occur during the earlier years of 

 development and reaches its minimum in six years, when it is 

 followed by the period of accelerating growth during the remain- 

 ing five years out of the eleven over which observations extended.

 obtained from Quebec, and it is hoped that an annual grant may 

 be secured from the same source. It is also believed that a work 

 of such eminent public utility, appealing, as it does, to wide and 

 important national interests, will also commend itself so fully to
