Part 11

MOUNTAIN JUNIPER (Juniperus sabinoides) is a Texas tree, occupying a range southward and westward of the Colorado river. It has several local names, rock cedar being a favorite. This name is due to the tree’s habit of growing on rocky ridges and among ledges where soil is scarce. It is called juniper cedar, and juniper. Under the most favorable circumstances the tree may attain a height of 100 feet and a diameter of two, but it nearly always grows where conditions are adverse, and its size and form change to conform to circumstances. It is often small and ragged. Its lead-colored bark is apt to attract attention on account of its woeful appearance, hanging in strings and tatters which persistently cling to the trunk in spite of whipping winds. When the tree is cut for fuel, or for any other purpose, the ragged bark is occasionally pulled off and is tied in bales or bundles to be sold for kindling. When the mountain juniper is taken from its native wilds and planted where environments are different, it sometimes assumes fantastic forms. It has been planted for ornament on the low, flat coast in the vicinity of the Gulf of Mexico, and though it lives and grows, it often takes on a peculiar appearance. The trunks resemble twisted and interwoven bundles of lead-colored vines, buttressed, fluted, and gnarled. The branches lose their upright position, and hang in careless abandon, with drooping festoons. In winter the wind whips most of the foliage from them. The leaves become brittle and may be easily brushed from the twigs by a stroke of the hand. Some of the planted trees have trunks so deeply creased as to be divided in two separate stems. This very nearly happens with some of the wild trees among the western mountains. The sapwood of mountain juniper is very thin. The average tree cannot be profitably cut into lumber of the usual dimensions because of the odd-shaped and irregular trunk. It lends itself more economically to the manufacture of articles made up of small pieces. Some of the wood is extremely beautiful, having the color and figure of French walnut; but there is great difference in the figure and color, and the wood of one tree is not a sure guide to what another may be. Boards a foot wide, or even less, may show several figures and colors. Some pieces suggest variegated marble; others are like plain red cedar; some are light red in color, others have a tinge of blue. It varies greatly in hardness, even in the same tree. Part of it may be soft and brittle enough for lead pencils; another part may be hard and tough. Clothes chests have been made of it, of most peculiar appearance--resembling crazy quilts of subdued colors. Sometimes the heartwood and the sapwood are inextricably mixed, both being found in all parts of the trunk from the heart out. On the whole, the tree can never have much importance as a source of lumber, but it is a most interesting member of the cedar group.

SOUTHERN WHITE CEDAR

SOUTHERN WHITE CEDAR

(Chamæcyparis Thyoides)

This tree is called southern white cedar to distinguish it from northern white cedar or arborvitæ. When there is little likelihood of confusion, the name white cedar is applied locally in different parts of its range from Massachusetts to Florida. It is a persistent swamp tree and on that account has been called swamp cedar; but that name alone would not distinguish it from the northern white cedar, for both grow in swamps; but it does separate it from red cedar which keeps away from swamps. The ranges of the two are side by side from New England to Florida. Post cedar is a common name for it in Delaware and New Jersey, because of the important place it has long filled as fence material; but again, the name does not set it apart from red cedar or northern white cedar, for both are used for posts. The only name thus far applied, which clearly distinguishes it from associated cedars, is southern white cedar. Its range extends northward to Maine, but the tree’s chief commercial importance has been in New Jersey and southward to North Carolina, very near the coast. Somehow, it seems to skip Georgia where no one has reported it for many years, though there is historical evidence that it once grew in that state. It grows as far west as Mississippi, but is scarce.

The small leaves remain green two years and then turn brown but adhere to the branches several years longer. The fruit is about one-fourth inch in diameter, and the small seeds are equipped with wings.

The wood is among the lightest in this country. It is only moderately strong and stiff. The tree usually grows slowly. Fifty years may be required to produce a fence post, but under favorable conditions results somewhat better than that may be expected. The summerwood of the yearly ring is narrow, dark in color, and conspicuous, making the counting of the rings an easy matter. The medullary rays are numerous but thin. When the sap is cut tangentially in very thin layers it is white and semi-transparent, presenting somewhat the appearance of oiled paper. The heartwood is light brown, tinged with red, growing darker with exposure. The wood is easily worked, and is very durable in contact with the soil. Fence posts of this wood have been reported to stand fifty years, and shingles are said to last longer. Trees reach a height of eighty feet and diameter of four; but such are of the largest size. Great numbers are cut for poles and posts which are little more than a foot in diameter. Few forest trees grow in denser stands than this. It often takes possession of swamps, crowds out all other trees, and develops thickets so dense as to be almost impenetrable. Southern white cedar is cut in ten or twelve states, but the annual supply is not known, because mills generally report all cedars as one, and the regions which produce this, produce one or more other species of cedar also. It has held its place nearly three hundred years, and much interesting history is connected with it. A considerable part of the Revolutionary war was fought with powder made from white cedar charcoal burned in New Jersey and Delaware. However, that was by no means the earliest place filled by this wood.

Two hundred years ago in North Carolina John Lawson wrote of its use for “yards, topmasts, booms, bowsprits for boats, shingles, and poles.” It was cut for practically the same purposes in New Jersey at an earlier period, and 160 years ago Gottlieb Mittelberger, when he visited Philadelphia, declared that white cedar was being cut at a rate which would soon exhaust the supply. But that prophecy, like similar predictions that oak and red cedar were about gone, proved not well founded. Seventy years after the imminent exhaustion of this wood was foretold, William Cobbett, an English traveler, declared with evident exaggeration that “all good houses in the United States” were roofed with white cedar shingles.

After boat building, the first general use of the southern white cedar was for fences and farm buildings, and doubtless twenty times as much went to the farms as to the boat yards. In all regions where the wood was convenient, little other was employed as fencing material, and many of the earliest houses in New Jersey and some in Pennsylvania were constructed almost wholly of this wood. Small trees which would split two, three, and four rails to the cut, were mauled by thousands to enclose the farms. The bark soon dropped off, or was removed, and the light rails quickly air-dried, and decay made little impression on them for many years. The larger trunks were rived for shingles or were sawed into lumber. About 1750 the use of round cedar logs for houses and barns began to give way to sawed lumber. It was an ideal milling timber, for the logs were symmetrical, clear, and easily handled. North Carolina sawmills were at work on this timber many years before the Revolution. It was acceptable material for doors, window frames, rafters, and floors, but especially for shingles which were split with frow and mallet, and were from twenty-four to twenty-seven inches long. They were known in market as juniper shingles and sold at four and five dollars a thousand. About 1750 builders in Philadelphia were criticized because they constructed houses with no provision for other than white cedar roofs; the walls being too weak for heavier material which would have to be substituted when cedar could be no longer procured. Philadelphia was not alone in its preference for cedar roofs. Large shipments of shingles were going from New Jersey to New York, and even to the West Indies earlier than 1750.

Southern white cedar is said to have been the first American wood used for organ pipes. The resonance of cedar shingles under a pattering rain suggested this use to Mittelberger when he visited America, and he tried the wood with such success that he pronounced it the best that he knew of for organ pipes.

Coopers were among the early users of white cedar. The “cedar coopers of Philadelphia” were famous in their day. They used this wood and also red cedar (Juniperus virginiana), and their wares occupied an important place in domestic and some foreign markets. Small vessels prevailed, such as pails, churns, firkins, tubs, keelers, piggins, noggins, and kegs. The ware was handsome, strong, durable, and light in weight. Oil merchants, particularly those who dealt in whale oil which was once an important commodity, bought tanks of southern white cedar. It is a dense wood and seepage is small.

A peculiar superstition once prevailed, and has not wholly disappeared at this day, that white cedar possessed powerful healing properties. It was thought that water was purified by standing in a cedar bucket, and even that a liquid was improved by simply running through a spigot of this wood. Some eastern towns at an early period laid cedar water mains, partly because the wood was known to be durable, and partly because it was supposed to exercise some favorable influence upon the water flowing through the pipes. It was even believed that standing trees purified the swamps in which they grew. Vessels putting to sea from Chesapeake bay, sometimes made special effort to fill their water casks with water from the Dismal swamp, where cedars grew abundantly in the stagnant lagoons.

About 100 years ago it was found that whole forests of cedar had been submerged in New Jersey during prehistoric times, and that deep in swamps the trunks of trees were buried out of sight. No one knows how long the prostrate trees had lain beneath the accumulation of peat and mud, but the wood was sound. Mining the cedar became an important industry in some of the large swamps, and it has not ended yet. The wood is sound enough for shingles and lumber, though it has been buried for centuries, as is proved by the age of the forests which grew over the submerged logs. Sometimes a log which has lain under water hundreds of years, rises to the surface by its own buoyancy when pressure from above is removed. This is remarkable and shows how long a time this cedar resists complete waterlogging. The wood of green cedar has a strong odor, and that characteristic remains with the submerged trunks. Experienced men who have been long engaged in mining the timber, are able to tell by the odor of a chip brought to the surface from a deeply submerged log whether the wood is sufficiently well preserved to be worth recovering and manufacturing. Trunks six feet in diameter have been brought to the surface. Few if any living white cedars of that size exist now.

Many of the early uses of southern white cedar have continued till the present time, but in much smaller quantities. Fence rails are no longer made of it; shingles and cooperage have declined. On the other hand, it now has some uses which were unknown in early times, such as telephone and telegraph poles, crossties, and piling for railroad bridges and culverts.

The supply of southern white cedar is not large, and it is being cut faster than it is growing. The deep swamps where it grows protect white cedar forests from fire, and for that reason it is more fortunate than many other species. Not even cypress can successfully compete with it for possession of water soaked morasses. It does not promise great things for the future, for it will never be extensively planted. Its range has been pretty definitely fixed by nature to deep swamps near the Atlantic coast. Within those limits it will be of some importance for a long time. Where it finds its most congenial surroundings, little else that is profitable to man will grow. This will save it from utter extermination, because much of the land which it occupies will never be wanted for anything else.

INCENSE CEDAR

INCENSE CEDAR

(Libocedrus Decurrens)

In California and Oregon this tree is known as white cedar, cedar, and incense cedar; in Nevada and California it is called post cedar and juniper, and in other localities it is red cedar and California post cedar. It is a species of such strong characteristics that it is not likely to be confused with any other. Though different names may be applied to it, the identity of the tree is always clear.

Its range extends north and south nearly 1,000 miles, from Oregon to Lower California. It is a mountain species, and it faces the Pacific ocean in most of its range. In the North it occupies the western slope of the Cascade mountains in southern Oregon and northern California; and it grows on the western slope of the Sierras for five hundred miles, at altitudes of from 4,000 to 8,000 feet, where it is mixed with sugar pine, western yellow pine, white fir, and sequoias.

It is a fine, shapely tree, except that the butt is much enlarged. It has the characteristic form of a deep swamp tree, but it has nothing to do with swamps. Its best development is on the Sierra Nevada mountains, where swamps are few, and the incense cedar avoids them. It occupies dry ridges and slopes, but not sterile ones. It must have as good soil as the sugar pine demands. Its height when mature ranges from seventy-five to 125 feet, diameter four feet from the ground, from three to six feet, but some trees are larger. It is not a rapid grower, but it maintains its vigor a long time. As an average, it increases its diameter an inch in from seven to ten years.

The wood is dense. It contains no pores large enough to be seen with an ordinary reading glass. The medullary rays are so small as to be generally invisible to the naked eye, but when magnified they are shown to be thin and numerous. The summerwood forms about one-fourth of the annual ring. The wood is nearly as light as white pine, is moderately strong, is brittle, straight grained, the heartwood is reddish, the thick sapwood nearly white. It is an easy wood to work, and in contact with the soil it is very durable.

The incense cedar is the only representative of its genus in the United States. It has many relatives in the pine family, but no near ones. Its kin are natives of Formosa, China, New Zealand, New Guinea, and Patagonia.

The name incense cedar refers to the odor of the wood rather than of the leaves. Those who work with freshly cut wood are liable to attacks of headache, due to the odor; but some men are not affected by it.

The forest grown tree is of beautiful proportions. Unless much crowded for room, it is a tall, graceful cone, the branches drooping slightly, and forming thick masses. In the Sierra Nevada mountains, within the range of this cedar, the winter snows are very heavy. It is not unusual for two or three feet of very wet snow to fall in a single day. The incense cedar’s drooping branches shed the snow like a tent roof, and a limb broken or seriously deformed by weight of snow is seldom seen. Deer and other wild animals, when surprised by a heavy fall of snow, seek the shelter of an incense cedar, if one can be found, and there lie in security until the storm passes.

It is a tree which does fairly well in cultivation, and several varieties have been developed. It lives through the cold of a New England winter. Its cones are about three-fourths inch in length, and ripen in the autumn.

Incense cedar has filled an important place in the development of the great central valley of California, where it has supplied more fence posts than any other tree. Posts of redwood have been its chief competitor, but generally the region has been divided, and each tree has supplied its part. The redwood’s field has been the coast, the cedar’s the inland valley within reach of the Sierras. It has been nothing unusual for ranchmen to haul cedar posts on wagons forty or fifty miles.

The manufacture of posts from incense cedar has entailed an enormous waste of timber. The thick sapwood is not wanted, and in the process of converting a trunk into posts, the woodsman first splits off the sap and throws it away. In trunks of small and medium size, the sapwood may amount to more than the heartwood, and is a total loss.
