varieties, and for unnumbered uses, a tithe of which cannot be told in a
brief notice. Formerly these trees were cut away and burned up, to clear
the track for redwood, tamarack, and ponderous pith-pines, etc.; now all
else is superseded by this incense cedar. Thus is seen how hasty and
ill-advised notions give place to genuine merit.
A fungus (_daedalus_) attacks and honeycombs it; and riddled as it may
occasionally be, still, if spike or nail finds substance enough to hold,
or sufficient solidity to resist crushing, then, for many purposes, even
such lumber is practically as good as the soundest timber; because when
the tree dies the fungus dies, and thenceforth will absorb no more
moisture than the soundest part, and is alike imperishable, contrary to
common experience in similar cases. This is a timber nearly as lasting
as solid granite. For ship or boat lumber, the clear stuff from sound
wood is so exceedingly light, stiff, and durable, and so plenty and
available, that few timbers excel it, unless the yellow cedar or cyprus
(_Cupressus nutkaensis_) is excepted, which is a little tougher,
stronger, perhaps more elastic, and equally durable, if judged apart
from thorough tests and careful data, which, it has been remarked, the
apathy or ignorance of some governments appear to deem unworthy their
sublime attention. There are said to be in California a thousand times
more and better kinds of naval timbers on government lands as important
to preserve as the live oaks of the South Atlantic States. It has been
asserted as probable that, after due investigation, California would be
found to possess a vast amount of the best naval timber in the world, a
hundredfold more lasting than the best now in use, if a few woods are
excepted, of which there is understood to be no very adequate supply.
