Here we are face to face with the drawback of close plant- 
ing. This will be best illustrated by quoting from the Register of 
Trees and shewing the very small increment of growth for 12 
months with trees which had been too closely planted (see num- 
bers 100 to 173) and comparing these with a single line and other 
trees well distanced as shewing a satisfactory increment of growth 
for the year (see numbers 1212 to 1285). In the first lot of trees, 
or closely planted ones, the trees were “spokeshaved” or roughly 
cleaned for tapping before being measured, and for a tree with 
deep corrugated bark due allowance must be made. Only a few 
of the second lot of trees, or open planted ones, had been tapped 
but this point need not be considered as trees well distanced shew 
a satisfactory increment of growth whether tapped or not.
