L, 201 in., or an average rate per annum of . ; 565 in. 
Another 38 years brings us to 1860, or an age of 
76 years, when the size was 45 in., or an 
average of : : ; : “592 in. 
The last 38 years shows the increase to be slightly in excess of 
the first 38. 
M had increased in 1822 to 262 in., or an average 
rate of ; : E : “609 in. 
, In another 38 years it me increased to 43 in., or 
an average rate of ; . ; 5 ‘563 in. 
Then take two of the transplanted for the same periods, as 
follows :— 
A had increased in 1822 to 262 in., or an average of 641 in. 
, In 1860 it had increased to 744 in., or an average of -936 in. 
B had increased in 1822 to 254 in., or an average of -664 in, 
, In 1860 it had increased to 69} in., or an average of “91 )-m: 
The first thing that strikes one with reference to the above is 
the great difference in size between the non-transplanted and 
those that were. In the 76 years “A,” a transplanted one, 
exceeded “LL,” a non-transplanted, -344 in. per annum, and “B” 
exceeded “ M” in the same time by ‘348 in. Now it is difficult 
to believe that the mere fact of transplanting would result in such 
a difference, all other conditions being equal, and this at the end 
of 76 years, without any other reason than that the tree was trans- 
planted. I have taken the period of 76 years, because I happen 
to be well acquainted with a selfsown wood of about the same 
age, and in 1888 measured several, with the following results :— 
No. 1 had a circumference of 60 in. at 5 feet up, or 
an average increase per annum of : ‘ *789 in. 
The bole or trunk was 60 feet, and the sheer 
height 80 feet. 
No. 2 had a circumference of 65} in., or an average 
increase per annum of nearly . ; 862 in. 
The bole or trunk 40 feet, and the sheer helt 
80 feet. 
No. 3 had a circumference of 74 in., or an average 
increase per annum of : °970 in. 
The bole or trunk 30 feet, and ihe sheer height 
also 80 feet.
