THE GIRTH-INCREASE OF TREES. IOI 
died, the increase falling to 35. In the next two years the tree 
revived, the increase rising to about an inch annually, still far 
below 1892, but with the second half-season again in excess. It 
seems probable, therefore, that this is the rule. The highest 
single records were—April 10, May 20, June 40, July 55, August 
45, September 5. 
I have been able to give seven years’ results, as this tree was 
only very slightly pruned in 1896, It is the only one of the 
species that I have observed.

The single Ash, No. 2, agrees in the main with the two 
younger trees of 1887-91. In both the second half-season is 
greatly inferior to the first, and June is by far the best month. 
The chief difference is the greater April growth of No. 2, but 
taking April and May together the proportions are almost 
identical. 
No. 2 furnishes all the highest single scores, 10 in April, 30 in 
May, 55 in June, 45 in July, 15 in August, the annual increase 
having been much greater than in the other two, which were 
comparatively in their infancy..
