fallen far above of or under that.
An attempt to reproduce here some considerable number of the growth
and it produces tables they would be of doubtful use without more spatial than
it is permitted to explain as they is done and they is used. There am many
technicality, both mathematical and silvicultural, and unfortunately
the most greater part of the available figures for the Northwest, got from the
Service of forest, has not been generalized enough for wide popular
value. This is particularly true of tables of product that necessarily
asks for conceited standard of merchantability. While the western best
white table of pine supposes that from the duration a new crop you/he/she is cut 7-thumb
white pine will be venal, the best table of fir works on
a basic 12-thumb of diameter. This would evidently show unjustly a
greater product of a forest of pine that contains trees among 7 and 12
thumbs and it is a lot misguiding in to calculate financial results to
the same age and percentages of stumpage; still without the original data
there is not any way of reducing both the tables to the same base. As a
however, example to point out as the financial possibilities of
second growth can have arrived to if a systematic study is made,
I/you/he/she allow us to pick up the Douglas to whom figures of fir have referred.
DOUGLAS FIR
These are very reliable. Measurements were taken by the Forest
Service of practically pure fir on approximately 400 areas in thirty-five
stands of different age from 10 to 140 old, varying along the
western hills of Fall from the Canadian line to central Oregon.
Since investment of reforestation it will mainly be confined probably to
the most promising opportunities, only such growth was measured
as it gave a two best class middle representation
owes the whole covered general territory both classified in two qualities
classes of all around the ability to produce forests. On the other
gives, care was taken not to represent the maximum one any best
you classify, gives that they are only taken by earth of permanent forest and not
