The years 1889, 1895, and 1898 were referred to when 

 discussing the evergreens. Like the evergreens, the seven 

 deciduous trees have an increased growth in these three 

 years. 



The worst year for evergreens was 1893, but 1892 is 

 the worst for deciduous trees, — this year has already been 

 mentioned as nearly as bad as 1893 for evergreens, — its 

 rain deficiency is the greatest in fourteen years, it has more 

 sunshine (especially in the sleeping season) than any other 

 year, and its temperature — excepting the sleeping season 

 minima — is above the average. This does not seem as if 

 sunshine were of great value to tree-growth. 



These speculations may be summed up as follows : — The 

 best growths of evergreen and deciduous, trees have always 

 been accompanied by an over-average rainfall, and, with one 

 exception, by deficiency of sunshine; in 1889 and 1898, 

 with an under-average temperature; and in 1895, with an 

 over-average temperature in the sleeping season. The 

 worst growths always occur with a deficiency of rainfall, 

 and, with one exception, an over-average of sunshine ; also, 

 an over-average temperature in the growing season, and an 

 under-average temperature in the sleeping season. 



As previously mentioned, locusts did much harm in the 

 end of 1896 and the beginning of 1897; and tliis harm is 

 indicated generally in the growth-curve diagrams for these 

 two years, for I present, with these notes, diagrams showing 

 the monthly growth of each species of trees for each of nine 

 years ; besides another diagram with the total average 

 monthly growth-curves for the whole term, each diagram 

 with notes of the weather for that particular year. 



The diagram for 1896 shows how the Gum trees fell 

 back in October ; the Tines and Blackwoods suffering in 

 November, and falling back in December; the Oaks, 

 Paraisos, and llobinia showing biii a slow gro«?th : and 

 the Poplars, little growth at all in the last three months of
