No. IX.
Those who have only lived in forest countries, where vast tracts are
shaded by a dense growth of oak, ash, chestnut, hickory, and other trees
of deciduous foliage, which present the most pleasing varieties of
verdure and freshness, can have but little idea of the effect produced
on the feelings by aged forests of pine, composed in a great degree of a
single species, whose towering summits are crowned with one dark green
canopy, which successive seasons find unchanged, and nothing but death
causes to vary. Their robust and gigantic trunks rise an hundred or more
feet high, in purely proportioned columns, before the limbs begin to
diverge; and their tops, densely clothed with long, bristling foliage,
intermingle so closely as to allow of but slight entrance to the sun.
Hence, the undergrowth of such forests is comparatively slight and thin,
since none but shrubs, and plants that love the shade, can flourish
under this perpetual exclusion of the animating and invigorating rays of
the great exciter of the vegetable world. Through such forests, and by
the merest foot-paths, in great part, it was my lot to pass many miles
almost every day; and had I not endeavoured to derive some amusement and
instruction from the study of the forest itself, my time would have been
as fatiguing to me, as it was certainly quiet and solemn. But wherever
nature is, and under whatever form she may present herself, enough is
always proffered to fix attention and produce pleasure, if we will
condescend to observe with carefulness. I soon found that even a
pine-forest was far from being devoid of interest, and shall endeavour
to prove this by stating the result of various observations made during
the time I lived in this situation.
The common pitch, or, as it is generally called, Norway pine, grows from
a seed, which is matured in vast abundance in the large cones peculiar
to the pines. This seed is of a rather triangular shape, thick and heavy
at the part by which it grows from the cone, and terminating in a broad
membranous fan or sail, which, when the seeds are shaken out by the
wind, enables them to sail obliquely through the air to great distances.
Should an old corn-field, or other piece of ground, be thrown out of
cultivation for more than one season, it is sown with pine-seeds by the
winds, and the young pines shoot up as closely and compactly as hemp.
They continue to grow in this manner until they become twelve or fifteen
feet high, until their roots begin to encroach on each other, or until
the stoutest and best rooted begin to overtop so as entirely to shade
the smaller. These gradually begin to fail, and finally dry up and
perish, and a similar process is continued until the best trees acquire
room enough to grow without impediment. Even when the young pines have
attained to thirty or forty feet in height, and are as thick as a man's
thigh, they stand so closely together that their lower branches, which
are all dry and dead, are intermingled sufficiently to prevent any one
from passing between the trees, without first breaking these
obstructions away. I have seen such a wood as that just mentioned,
covering an old corn-field, whose ridges were still distinctly to be
traced, and which an old resident informed me he had seen growing in
corn. In a part of this wood, which was not far from my dwelling, I had
a delightful retreat, that served me as a private study or closet,
though enjoying all the advantages of the open air. A road that had once
passed through the field, and was of course more compacted than any
other part, had denied access to the pine-seeds for a certain distance,
while on each side of it they grew with their usual density. The ground
was covered with the soft layer or carpet of dried pine leaves which
gradually and imperceptibly fall throughout the year, making a most
pleasant surface to tread on, and rendering the step perfectly
noiseless. By beating off with a stick all the dried branches that
projected towards the vacant space, I formed a sort of chamber, fifteen
or twenty feet long, which above was canopied by the densely-mingled
branches of the adjacent trees, which altogether excluded or scattered
the rays of the sun, and on all sides was so shut in by the trunks of
the young trees, as to prevent all observation. Hither, during the hot
season, I was accustomed to retire for the purpose of reading or
meditation; and within this deeper solitude, where all was solitary,
very many of the subsequent movements of my life were suggested or
devised.
From all I could observe, and all the inquiries I could get answered, it
appeared that this rapidly-growing tree does not attain its full growth
until it is eighty or ninety years old, nor does its time of full health
and vigour much exceed an hundred. Before this time it is liable to the
attacks of insects, but these are of a kind that bore the tender spring
shoots to deposit their eggs therein, and their larvae appear to live
principally on the sap, which is very abundant, so that the tree is but
slightly injured. But after the pine has attained its acme, it is
attacked by an insect which deposits its egg in the body of the tree,
and the larva devours its way through the solid substance of the timber;
so that, after a pine has been for one or two seasons subjected to these
depredators, it will be fairly riddled, and, if cut down, is unfit for
any other purpose than burning. Indeed, if delayed too long, it is
poorly fit for firewood, so thoroughly do these insects destroy its
substance. At the same time that one set of insects is engaged in
destroying the body, myriads of others are at work under the bark,
destroying the sap vessels, and the foliage wears a more and more pale
and sickly appearance as the tree declines in vigour. If not cut down,
it eventually dies, becomes leafless, stripped of its bark, and, as the
decay advances, all the smaller branches are broken off; and it stands
with its naked trunk and a few ragged limbs, as if bidding defiance to
the tempest which howls around its head. Under favourable circumstances,
a large trunk will stand in this condition for nearly a century, so
extensive and powerful are its roots, so firm and stubborn the original
knitting of its giant frame. At length some storm, more furious than all
its predecessors, wrenches those ponderous roots from the soil, and
hurls the helpless carcass to the earth, crushing all before it in its
fall. Without the aid of fire, or some peculiarity of situation
favourable to rapid decomposition, full another hundred years will be
requisite to reduce it to its elements, and obliterate the traces of its
existence. Indeed, long after the lapse of more than that period, we
find the heart of the pitch-pine still preserving its original form,
and, from being thoroughly imbued with turpentine, become utterly
indestructible except by fire.
If the proprietor attend to the warnings afforded by the wood-pecker, he
may always cut his pines in time to prevent them from being injured by
insects. The wood-peckers run up and around the trunks, tapping from
time to time with their powerful bill. The bird knows at once by the
sound whether there be insects below or not. If the tree is sound, the
wood-pecker soon forsakes it for another; should he begin to break into
the bark, it is to catch the worm; and such trees are at once to be
marked for the axe. In felling such pines, I found the woodmen always
anxious to avoid letting them strike against neighbouring sound trees,
as they said that the insects more readily attacked an injured tree than
one whose bark was unbroken. The observation is most probably correct;
at least the experience of country folks in such matters is rarely
wrong, though they sometimes give very odd reasons for the processes
they adopt.
A full-grown pine-forest is at all times a grand and majestic object to
one accustomed to moving through it. Those vast and towering columns,
sustaining a waving crown of deepest verdure; those robust and rugged
limbs standing forth at a vast height overhead, loaded with the cones of
various seasons; and the diminutiveness of all surrounding objects
compared with these gigantic children of nature, cannot but inspire
ideas of seriousness, and even of melancholy. But how awful and even
tremendous does such a situation become, when we hear the first wailings
of the gathering storm, as it stoops upon the lofty summits of the pine,
and soon increases to a deep hoarse roaring, as the boughs begin to wave
in the blast, and the whole tree is forced to sway before its power. In
a short time the fury of the wind is at its height, the loftiest trees
bend suddenly before it, and scarce regain their upright position ere
they are again obliged to cower beneath its violence. Then the tempest
literally howls, and amid the tremendous reverberations of thunder, and
the blazing glare of the lightning, the unfortunate wanderer hears
around him the crash of numerous trees hurled down by the storm, and
knows not but the next may be precipitated upon him. More than once have
I witnessed all the grandeur, dread, and desolation of such a scene, and
have always found safety either by seeking as quickly as possible a spot
where there were none but young trees, or, if on a main road, choosing
the most open and exposed situation out of the reach of the large trees.
There, seated on my horse, who seemed to understand the propriety of
such patience, I would quietly remain, however thoroughly drenched,
until the fury of the wind was completely over. To say nothing of the
danger from falling trees, the peril of being struck by the lightning,
which so frequently shivers the loftiest of them, is so great as to
render any attempt to advance at such time highly imprudent.
Like the ox among animals, the pine-tree may be looked upon as one of
the most universally useful of the sons of the forest. For all sorts of
building, for firewood, tar, turpentine, rosin, lamp-black, and a vast
variety of other useful products, this tree is invaluable to man. Nor is
it a pleasing contemplation, to one who knows its usefulness, to observe
to how vast an amount it is annually destroyed in this country, beyond
the proportion that nature can possibly supply. However, we are not
disposed to believe that this evil will ever be productive of very great
injury, especially as coal fuel is becoming annually more extensively
used. Nevertheless, were I the owner of a pine-forest, I should exercise
a considerable degree of care in the selection of the wood for the axe.
