The low rate of 10} for the first two years may have been due 
to transplantation, as next year it rose to 164, continuing nearly 
at the same for five years. Transplantation then reduced it for 
two years to 3. Next year—1897—It jumped to 153, and an 
enhanced rate of 20 was maintained till 1901, when it fell to 164 
for three years, possibly due to the removal of neighbouring trees 
and shrubs, which may have interfered with its roots. It was 
then retransplanted, and the increase in 1905 and 1906 fell to 
8 and 7; but the tree looks well.

This companion of the last, and a little larger at first, had a 
rather lower rate for the first two years, which probably succeeded 
transplantation, and a rather better rate than that of No. 1 for 
the next six years. It was transplanted a year later than the 
other, and took a year longer than it to recover. Even then the 
rate was low, and a depression to 6 for the two years 1903 
and 1904 followed, which it is difficult to explain ; a recovery to 
13 in 1905 and 15} in 1906 gives hope that the tree may yet do
