left even if every tree will be a total loss before a second
cut is possible.

"Extensive areas of pine timber which are not yet fully mature
should be excluded from the sale. On patches or small areas of
immature pine, which it is not practicable to exclude from the
sale, cutting should be very light, limited to one-third or less
of the largest trees, or omitted altogether.

"No attempt to discriminate sharply between sugar and yellow pine
should be made, as both trees are almost equally desirable. Where a
choice is necessary, sugar pine should be favored on moist situations,
as in canyons, moist pockets, or benches and on northerly exposures.
Yellow pine should be favored on dry situations, including exposed
ridges and southern exposures.

"Fir and incense cedar should be marked, as a rule, to as low a
diameter as these trees are merchantable in order to reduce the
proportion of these species in coming reproduction. It is essential,
however, that no large openings be made in the present stand since
the exposed ground is in danger of reverting to chaparral or of
becoming so dry from evaporation that no reproduction will follow
cutting. Where the stand of pine is insufficient to reseed thoroughly
and protect the cut-over area, enough sound, thrifty fir and cedar
should be left to form a fairly even cover with openings less than
a quarter of an acre in size.'"

The under current of all opinion upon sugar pine up to date is
that reproduction will not be very successful unless enough growth
to shelter the seedlings remains after logging. Where the fire
risk permits, the same end may be furthered by leaving the tops
scattered on the ground.

Little experimenting has been done in planting sugar pine, but
there are many indications that except where conditions strongly
favor natural reproduction it will be resorted to eventually if
any particular attempt is made to get this species. Leaving large
seed trees is not only expensive, but rather uncertain, because
heavy seed years are several years apart and squirrels consume a
large portion of an ordinary crop. Transplants which have received
nursery shelter until past the greatest danger of drying out should
prove most successful on heavily-cut south slopes.

REDWOOD (_Sequoia sempervirens_)

Although probably the most rapid-growing of all American commercial
trees and also of high market standing, redwood has been little
studied by foresters. The layman is still more
