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
