Capitolo 60
"2. Assuring a second cut in thirty years.
"Every cut should be done under the 'system of selection', what
he/she forces an accurate choice of the individual trees to be removed.
Fixed diameter limits and the to go away of some they specified number of
you sow trees for acrid you/he/she can very greatly be neglected.
"The condition of every sugar and yellow pine on the area of sale
you/he/she should be studied from near to determine if that tree will be
from now thirty marketable years from which it is per second time cut
probable. As a rule the trees for which you/they will be marketable
another thirty years should be gone away. Suppressed and crowded trees
what you/he/she cannot develop you/he/she should be removed. Under this system to mark,
ordinarily around one-mean of the present stand of marketable
pine would have gone away uncut. Will it pay?
"On areas where practically the whole pine is end-matured and
you/he/she would be cut under the rule it dates above of, an enough stand has to be
gone away completely to reseed the cut-ended earth. This doesn't require less
what four full trees seed-that hands, at least 25 thumbs in diameter,
for acrid. The strongest and you plant with trees more economical available you/he/she should be
selected for this purpose, but not less that the number specified
you/he/she must have gone away even if every tree will be a total loss of forehead to a second
cut is possible.
"Wide areas of lumber of pine that it is not completely mature yet
you/he/she should be excluded by the sale. On rolls or the small areas of
immature pine that is not practicable to exclude from the
sale, to cut should be very light, it limited to a bystander or less
of the greatest trees, or it omitted together.
"Any attempt to brusquely discriminate between sugar and yellow pine
as double should be done the trees they are almost equally desirable. Where a
choice is necessary, pine of sugar should be favorite on damp situations,
as in canyon, damp pockets or benches and on northern exposures.
Yellow Pino should be favorite on dry situations, included statement
