THE GIRTH-INCREASE OF DECIDUOUS TREES. 6! 
CYTISUS LABURNUM.. No.1. 
On its original site in the west border. Girthed 84 inches in 
1892 and increased at the rate of 164 till pruned in 1896, in which 
year the increase fell to 74, and for the eleven years till 1896 the 
rate has been no more than 83, varying between 64 and 173, and 
showing no sign of improvement latterly. 
FAGUS SYLVATICGA.: No. 20. 
Always in the north border till transplanted in 1905 to form 
part of a new row of beeches near the west border. Girthed 134 
inches in 1892 and increased for three years at the rate of 364 
mil. Pruned in 1896, the increase for that year was 15, and the 
average for three years 14. In 1899 it revived to 204, and that 
rather low rate for a beech of its age was not improved on for 
five years, when the tree was transplanted. 
FRAXINUS EXCELSIOR. No. 2. 
In its original position in the west border. Girthed 12 inches 
in 1892, and the rate for four years to 1896 was 303 mil. Pruned 
in that year, the increase fell to 164, and the rate till 1896 
was only 134. Neither has there been much improvement since, 
as for the seven years 1899-1905 the rate was 17, and the increase 
for 1906 was no more than 14. 
POPULUS FASTIGIATA. No.9. 
Stood in the west shelter belt and girthed 84 inches in 1892, 
and for four years increased at the rate of 314 mil. Pruned in 
the spring of 1896, the rate fell in the following four years to 173, 
but recovered in the next two to 26, when the tree was trans- 
planted to the poplar group. 
PRUNUS PADUS. No. 5. 
Always close to the Lodge, Arboretum Gate. Girthed 124 
inches in 1892, and in that year had the extraordinary increase 
of 2 inches—said to be, perhaps, due to its site being on a former 
midden. The rate continued as high as 454 mil. till 1896, when, 
after pruning, the increase fell to 274 in that year and the rate 
to 25 for six years. There has been a further decline to 19 in
