56 CHRISTISON—ADDITIONAL OBSERVATIONS ON 
A companion of No. 69, and of the same size in 1887, this tree’ 
had the lower rates of 13} and 164 in the first and second quin- 
quennia, as compared with 17} and 21. For some unrecorded 
or unknown reason the increase in 1897 fell to 14; but in 1898 
it sprung up to 164, and the tree must have been considered to 
be in guvod condition, as it was transplanted. Two years 
followed, the first with no increase, the second with only 9 ; but 
next year it amounted to 173, when the tree was again trans- 
planted, once more with the result of no increase in the first 
year, and the rate for the succeeding four years down to 1906 
was only 74. The tree looks healthy enough.

The wych elm is the most thriving and quickest growing tree 
in the town gardens of Edinburgh, and No. 94, with its former 
neighbour No. 93, are among the best of all the trees under my 
observation. They stood together in the original east belt of 
the Arboretum, which was done away with, No. 93 being almost 
the only tree that was not removed. 
No, 94 is now a handsome spreading specimen in its new site 
in the main avenue of the Arboretum. Transplanted in 1892, its 
rate fell from an average of 36} to 23 in that year, and, improving 
in the next two years, had wholly recovered with an increase of 
393 in 1895. Its rate for four periods between 1888 and 1905, 
excluding the three years when it was affected by removal, has 
been remarkably uniform, varying only from 35 to 364. 
REMARKS. 
Large Trees——As far as can be judged from the small number 
of trees between 3 and nearly 5 feet in girth that were trans- 
planted in 1896, the risk of death from the operation in trees of
