Except the two fir ft afh trees, I find the growth of oak and 
afh to be nearly the fame. I have fome of both fort? planted 
at the fame time, and in the fame hedges, of which the oaks 
are the largeft, but there is no certain rule as to that. The 
common growth of an oak or an afh is about an inch in girth 
in a year ; fome thriving ones will grow an inch and an half ; 
the unthriving ones not fo much, fome probably lefs than any 
here, for I chofe in general to meafure thofe that feemed 
thriving. 
Great trees grow more timber in a year than fmall ones ; for 
if the annual growth be an inch, a coat of one-fixth of ail 
inch is laid on all round, and the timber added to the body 
every year is its length multiplied into the thicknefs of 
the coat, and into the girth, and therefore the thicker the 
tree is, the more timber is added. The body of N° 9 is 9 feet 
long, the girth under the bark above 13 feet, the thicknefs of 
the coat 1. of an inch or t x t of a foot : then 9 x 1 3 x a. is one 
foot and fix-tenths of timber added in a year to the body, befide 
the increafe on all the branches, and it has a very great head ; 
one limb fquares 20 inches, and is itfelf equal to a moderate 
tree. 
The hedge in which N° 4. grows was planted in 1665, pro- 
bably the tree is not older than that year ; it has therefore in- 
creafed in girth about 1.3 inch every year fince it was fet. 
The oak, N° 5. I believe fowed itfelf; and I did not know 
there was fuch an one till about the year 1740, when the 
hedge being cut, the tree was found, and might be then 20 
years old or more. 
The two afh trees N° 20. and 21. grow much fafter than 
any of the reft, but are neither of them handfome growing 
trees. N° 20. has feveral feams where the bark is parting from 
the
