fill them up where thin, and to reftore them when 
in a ftate of decay. The expence is not only lef- 
fened by the faving of new fences, but the profit is 
greatly increafed, by the rapid growth of the wood, 
when planted in fituations that are fheltered by 
other wood already planted. 
In thofe woods where faplings fpring up in great 
numbers /pontaneoufly, their growth fhould by all 
means be encouraged. At the time of cutting the 
underwood, thefe faplings will perhaps be 14 or 
15 years old; and it might appear proper, after 
leaving for timber trees fuch as are ftrait and hand- 
fome, to cut off the reft for underwood. But great 
part of the faplings fo cut off at ‘bat age, will not 
be large enough to produce fhoots /uficiently firong 
to get up as faft as the other underwood. Thefe 
Jfooots would therefore fuffer, and the ftocks would 
never come to perfection. It is, therefore, more 
advifeable not to cut off fuch faplings as are in- 
tended for underwood, until the /econd cutting of 
the wood, when (being perhaps near 30 years old) 
they will throw out fhoots trong enough to fight 
their way, and keep pace with the furrounding 
underwood. 
Where faplings do not fpring up in abundance 
{pontaneoufly, young trees muft be planted; part of 
which may be preferved for timber, and the re- 
mainder left, to be ftubbed off at a proper time for 
underwood, :
