ARTICLE XIII. 
ON THE UTILITY OF PRUNING FOREST TREES. 
BY T. R. 
To prove the advantages arising from the system of pruning recom¬ 
mended so ably by many of your intelligent correspondents, I ven¬ 
ture to send you a statement of the growth of a few trees taken by a 
Scotch gentleman in September last, who employed some hours in 
carefully examining the plantations made in the winter of 1815 and 
1816, consisting of 300 acres of high mountain land, not calculated 
for any other purpose than the raising of timber. 
Many of the trees are much higher than those I have marked, but 
my object is to show the rapid increase of girth by annual gradual 
pruning, which many individuals, who have never given the system 
a fair trial, positively deny.
