Cedar tar and other tars or resins, such as eucalyptus, are the products of the psychic energy of the trees, and therefore they are extremely beneficial for strengthening, purifying, healing, etc. Knowing these qualities, everyone should try to apply them in the best possible way. The best tar is from Siberian cedars.
If purified, tars or their oil may be taken internally. Dose: five drops or more. Everything is very individual. Perhaps your intuition will help you to find the successful combinations. The emanations of pine trees are, of course, irreplaceable. Pine trees, like electric machines, accumulate vital forces, a condensed supply of prana, or naturovaloris. The Druids considered a chalice of pine essence as a chalice of life. It is always beneficial to have in rooms small pine trees or to spray the pine essences. In this way, the atmosphere is purified, and the undesirable entities, which are so numerous around the human emanations, are driven away. Essence of peppermint is also very good for this purpose—either sprayed in the air or put in hot water for evaporation. A cup of such water should be placed near the bedside. In all the cases you mentioned this would be useful. (28 August 1931)

"There is a tree. At the downhill edge of a long, narrow field in the western foothills of the La Sal Mountains — southeastern Utah. A particular tree. A juniper. Large for its species — maybe twenty feet tall and two feet in diameter. For perhaps three hundred years this tree has stood its ground. Flourishing in good seasons, and holding on in bad times. "Beautiful" is not a word that comes to mind when one first sees it. No naturalist would photograph it as exemplary of its kind. Twisted by wind, split and charred by lightning, scarred by brushfires, chewed on by insects, and pecked by birds. Human beings have stripped long strings of bark from its trunk, stapled barbed wire to it in using it as a corner post for a fence line, and nailed signs on it on three sides: NO HUNTING; NO TRESPASSING; PLEASE CLOSE THE GATE. In commandeering this tree as a corner stake for claims of rights and property, miners and ranchers have hacked signs and symbols in its bark, and left Day-Glo orange survey tape tied to its branches. Now it serves as one side of a gate between an alfalfa field and open range. No matter what, in drought, flood heat and cold, it has continued. There is rot and death in it near the ground. But at the greening tips of its upper branches and in its berrylike seed cones, there is yet the outreach of life.

I respect this old juniper tree. For its age, yes. And for its steadfastness in taking whatever is thrown at it. That it has been useful in a practical way beyond itself counts for much, as well. Most of all, I admire its capacity for self-healing beyond all accidents and assaults. There is a will in it — toward continuing to be, come what may."

The hornbeam... is not a wood that breaks easily and is very convenient to handle. Hence the Greeks call it "zygia," because they make of it yokes for their draught animals... Cypress and pine are also just as admirable; for although they... are apt to warp when used in buildings... they can be kept to a great age without rotting because the liquid contained within their substances has a bitter taste which by its pungency prevents the entrance of decay or of those little creatures which are destructive. Hence buildings made of these kinds of wood last for an unending period of time.

If a man knew enough he could write a whole book about the juniper tree. Not juniper trees in general but that one particular juniper tree which grows from a ledge of naked sandstone near the old entrance to Arches National Monument.

The fire. The odor of burning juniper is the sweetest fragrance on the face of the earth, in my honest judgment; I doubt if all the smoking censers of Dante's paradise could equal it. One breath of juniper smoke, like the perfume of sagebrush after rain, evokes in magical catalysis, like certain music, the space and light and clarity and piercing strangeness of the American West. Long may it burn.

The leaves of these [larch] trees are like those of the pine; timber from them comes in long lengths, is as easily wrought in joiner's work as is the clearwood of fir, and contains a liquid resin, of the color of Attic honey, which is good for consumptives.

The winter oak... is very useful in buildings but when in a moist place it takes in water to its centre... and so it rots. The Turkey oak and the beech both... take in moisture to their centre and soon decay. White and black poplar, as well as willow, linden, and the agnus castus... are of great service from their stiffness. ...they are a convenient material to use in carving.

The mountain tree plunders itself. The candle fat scorches itself. The cinnamon tree is edible, and thus it gets chopped down. The lacquer tree is useful, and thus it is cut down. Everyone knows how useful usefulness is, but no one seems to know how useful uselessness is.

In the construction of houses, choice of woods is made. Straight un-knotted timber of good appearance is used for the revealed pillars, straight timber with small defects is used for the inner pillars. Timbers of the finest appearance, even if a little weak, is used for the thresholds, lintels, doors, and sliding doors, and so on. Good strong timber, though it be gnarled and knotted, can always be used discreetly in construction.

Study the teachings of the pine tree, the bamboo, and the plum blossom. The pine is evergreen, firmly rooted, and venerable. The bamboo is strong, resilient, unbreakable. The plum blossom is hardy, fragrant, and elegant.

When you are in trouble or at your lowest point, and have no one in whom to confide, a hawthorn would be the right choice. There is a reason why hawthorns are home to fairies and known to protect pots of treasure. For wisdom, try a beech; for intelligence, a pine; for bravery, a rowan; for generosity, a hazel; for joy, a juniper; and for when you need to learn to let go of what you cannot control, a birch with its white-silver bark, peeling and shedding layers like old skin. Then again, if it's love you're after, or love you have lost, come to the fig, always the fig.

Trees which grow in places facing the course of the sun are not of porous fiber but are solid, being drained by the dryness... The trees in sunny neighborhoods, therefore, being solidified by the compact texture of their fiber, and not being porous from moisture, are very useful, so far as durability goes, when they are hewn into timber. The lowland firs, being conveyed from sunny places, are better than those highland firs, which are brought here from shady places.

Upon Inquiry from knowing Persons, I find that Norway or Swedish Tar, which is dark, thick and clear... is accounted the best for the general Uses... But that the Tar which is made of the Tops of -Trees... having lain long dead... after having either fallen... or being killed by the draining off their Sap... (These Tops are commonly called Light-wood, the poorer People making use of them instead of Candles:) This Tar being burned in a very strong Fire of such dry Wood, is of a very caustick, corroding Nature, so as to be hurtful to Ropes, &c. for which reason it is not used in the Royal Navy. But the American Tar, which is made of green Fir-Trees, with a less degree of Fire, is esteemed good, and is called green Tar...
