TRANSACTIOiVS AND PROCEEDINGS OF THE [Sess. lxv. 



We learii, also, from C, or from Table I., that deciduous 

 trees in the main follow the course observed by the ever- 

 greens ; but the minimum thermometer is only a little 

 above par; the rainfall averages more than 028 inch per 

 hour, and the lack of sunshine is more than four times as 

 many hours as the plus hours of rain. 



But in the case of the deciduous trees it seems needful to 

 separate them into growing and sleeping periods, as follows: — 



Sleeping season is estimated from 12th of March to 12th 

 of September inclusive : growing season is, of course, the 

 other six months. 



We find from the above little table that the over- 

 average growth of deciduous trees in the growing season is 

 accompanied by a decidedly low maximum thermometer 

 (25 deg. accumulated in six months against 32 deg. in 

 twelve months, as per Table I.) ; also by a minimum 

 thermometer slightly over par ; by an abundant rainfall of 

 nearly 0'30 inch per hour; and by five times as many 

 hours deficiency of sunshine as of over plus hours of rain. 



In the sleeping season the maximum thermometer 

 shows a slight deficiency ; the minimum thermometer is 

 almost at par ; the surplus rainfall is not quite one-third 

 of what it was in the growing season, and is a little over 

 0'25 inch per hour ; and the hours of deficient sunshine are 

 almost equal to the hours of surplus rain. However, 

 as the measured growth of the trees for the six sleeping
