TRANSACTIONS AND PROCEEDINGS OF THE [Sess. lxv. 



series of twelve monthly tables, in which the first column 

 gives half the measured monthly growth in millimetres 

 of six evergreens, and the second column the amount plus 

 or minus the average of seven years, the third and fourth 

 columns give the half growth, and the plus or minus 

 average of six deciduous trees. The evergreens are the 

 two Gum trees, two Pines, and two Blackwoods, and the 

 deciduous the two Paraisos, two Oaks, and two Poplars 

 referred to on pages 245, 246, etc. etc. of "More Notes on 

 Tree Measurement." The growth period is from 12th of 

 of one month to 12th of the next. 



The five succeeding weather columns represent the 

 monthly amount over or under the average of seven years. 

 The weather period is from the 12th of one month to the 

 11th of the next month inclusive. 



The summaries at the foot of each monthly table show 

 the total net weather factors for that month for all the 

 years when there was an over-average growth, as, also, for 

 all the years when there was an under-average growth. 



Thus, for growth period ending 12 th February —

After constructing these twelve monthly tables, I made 

 a synopsis of all their summaries, which we will call 

 Table I.
