Part 15

(Abies Balsamea)

Balsam fir is the usual name applied to this tree in New England, New York, Pennsylvania, Michigan, Wisconsin, Minnesota, and Ontario. The shorter name balsam suffices in some parts of that region, and particularly in New York, New Hampshire, and Vermont. Because it is common north of the international boundary, the name Canada balsam has been given it in some regions. In Delaware it is known as balm of Gilead, but that name belongs to a tree of the cottonwood group, (Populus balsamifera) which is a broadleaf species. In New York and Pennsylvania a word of distinction is added, and it is called balm of Gilead fir. Toward the southern limit of its range it is spoken of as fir pine and blister pine. New York Indians knew the tree as blisters. They referred to the pockets under the bark of young trees and near the tops of mature trunks, in which resin collected. The name balsam refers to that characteristic also, as does the word balm. In some parts of Canada the tree is known as silver pine, and as silver spruce. The secretion of resin in bark blisters is a characteristic of several firs.

The list of names and the locality of their use indicate fairly well the geographical range of balsam fir. Its northern limit forms a line across eastern Canada from Labrador to Hudson bay. From Hudson bay its northern boundary trends northwestward and reaches the vicinity of Great Bear lake. In the United States it grows westward to Minnesota and southward to Pennsylvania. It is cut for lumber in eleven states.

In a range so large and including situations so various, it is natural that the tree should vary greatly in size. In the Lake States the common height is fifty or sixty feet, and the diameter is twelve or fifteen inches. Young balsam firs grow vigorously when the ground is suitable and their tops receive sufficient light. In lumbered regions in the Lake States, this fir gets a foothold in the shade of a dense growth of paper birch and other quickly-growing species; and in a few years the pointed, intensely green spires of the balsams may be seen piercing the canopy of other young tree tops, and shooting above into the light. This is accomplished after a struggle of some years in the shade; but the firs ultimately win their way upward, and in a few years they shade to death most of their broadleaf associates. If they are in competition with northern white cedar or tamarack, they are not always successful in winning first place.

The leaves of balsam fir are from one-half to one and one-fourth inches long. They are green and lustrous above and silver white below, the whiteness due to stomata on their undersides. On young twigs the leaves bristle out on all sides and are very numerous and crowded together, but on older branches the leaves are more scattered, due to the dropping of some of them. It is their habit to adhere to the stems about eight years.

The leaves of balsam fir possess a pleasing and characteristic odor which is turned to account in a practical way. The small needles are stripped from the branches in large quantities, cleaned, dried, and are used for stuffing sofa pillows, cushions, and other kinds of upholstery. The odor persists a long time. Much of the collecting of the needles is done in summer as a pastime by summer campers in the northern woods. The needles are sufficiently tough to stand much wear in pillows, and they are still odorous when long use has ground them to powder.

The cones of balsam fir follow the fashion of all species of fir, and stand erect on the branches. Seeds are one-fourth inch in length and are winged. The wood is of approximately the same weight as white pine, but it falls considerably below white pine in strength and stiffness. It is of moderately rapid growth when conditions are favorable, and the annual ring has a fair proportion of summerwood. The yearly rings are quite distinct. The medullary rays are numerous, and for a softwood they are prominent. When a log is quarter-sawed, and the surfaces of the boards are planed, the wood presents a silvery appearance, but it is too monotonous to be very attractive. The heartwood is pale brown, streaked with yellow, the thick sapwood much lighter in color. It is perishable in contact with the soil.

Pulp manufacturers are the largest users of balsam fir. About three per cent of all the pulpwood cut in the United States in 1910 was from this species. Its use is on the increase, or appears to be; but recent statistics relating to this wood cannot be safely compared with returns for former years, because the custom of mixing fir with spruce and other pulpwoods formerly prevailed in New England, and it was then not possible to determine exactly how much fir reached the market. At the present time fir goes under its own name, and the output exceeds 132,000 cords, which is equivalent to 105,000,000 feet, board measure, yearly.

Eleven states contribute to the balsam fir lumber cut, but most is supplied by Maine, Minnesota, Vermont, Michigan, and Wisconsin. The total for 1910 was 74,580,000 feet. Much of it is employed in rough form for fences and buildings, while other is further manufactured by planing mills and factories. Car builders employ it in several ways. It serves as doors, siding, lining, and roofing for freight cars. It is not a durable wood when exposed to weather. The largest reported use of the wood in New England is by box makers. Massachusetts alone works nearly 15,000,000 feet a year into crates and shipping boxes. Its uses in the Lake States are more varied. The makers of berry, fruit, and vegetable baskets draw supplies from the wood. Some of the product is of thin split slats, and other of veneer or sawed material.

The light weight and white color of balsam fir make it acceptable to the manufacturers of excelsior. The product is employed in packing merchandise for shipment, and to a small extent in upholstery. The wood fills a rather important place in the woodenware industry, where its white color and light weight constitute its most important recommendations. It is sawed into staves for pails and tubs.

Though balsam fir has little figure and its appearance is rather common, it finds its way to planing mills and woodworking shops where it is made into ceiling, newel posts, molding, railing, spindles, chair-boards, and other interior finish.

The most widely known commercial product manufactured from this tree is Canada balsam. Strictly speaking, it is not a manufactured article except what is done in nature’s laboratory, and the product is the resin stored under bark blisters. The resin is transparent, and is employed by microscopists in mounting objects for examination. Little machinery or apparatus is used in removing the viscid fluid from the pockets in the bark. With a knife the thin, soft blister is slit and the resin is scraped out. All kinds of claims of medicinal virtue are made for balsam resin in the region where the tree grows; but the treatment in most cases effects cures--if any cures are really effected--by appeals to faith and the imagination.

Balsam fir owes a large part of its importance to its abundance. It is not exactly a swamp tree, but it does best in damp situations where the ground is moist and cool in summer. Only in periods of protracted drought does the ground litter become sufficiently dry to burn fiercely, and to that fact is due much of the promise of future supply of balsam fir. That which grows on the dry uplands may fall prey to forest fires, but that in the damp flats, associated with northern white cedar and tamarack, will hold its ground and continue to supply demand.

Balsam fir has an importance which can not be wholly measured in feet, pounds, cords, or dollars. Many of the choicest Christmas trees which in December go by tens of thousands to the cities, are of this tree. Its form is almost perfect, being conical, broad near the bottom, and running to a sharp apex. The deep green of the needles, which retain their color from two weeks to a month after the trunk is severed, gives balsam Christmas trees much of their popularity. The trees are cut from Maine to Michigan, and many are shipped across the international boundary from Canada. The custom of cutting Christmas trees is often condemned as a waste of resources. It has been argued that the destruction in one month of 1,000,000 young trees is equivalent to the destruction of 500,000,000 feet of lumber, because, if allowed to reach maturity, they would yield that much lumber. That argument does not take into consideration the fact that not one of the young trees in ten would reach maturity if left to the course of nature.

When Gifford Pinchot was United States forester, a protest against the cutting of Christmas trees was formally laid before him. It was generally believed that he would declare that the waste ought to be stopped and would set his disapproval on the practice; but he did nothing of the sort. He declared that the forests are for the use of the people and that they can serve in no better way than by supplying every child in the land with a Christmas tree once a year.

FRASER FIR

FRASER FIR

(Abies Fraseri)

The people who are acquainted with this interesting and somewhat rare tree have seen to it that it does not want for names. Some of these names are both definitive and descriptive, while others are neither. Tennessee, North Carolina, and West Virginia furnish the names. Within the tree’s range in Tennessee and North Carolina it is often known as balsam without any qualifying word, and that is quite sufficient, for no other fir or balsam grows within its range. In the same region it is called balsam fir. That is the common name of its northern relative, but there is little likelihood of confusing the two species, for their ranges do not overlap much, if they touch at all, which they probably do not. In Tennessee the name is reversed and instead of balsam fir it is fir balsam. It is likewise known as double fir balsam, but why “double” is added to the name is not clear. Similar mystery attaches to the name “single spruce,” which is applied to the balsam fir in the interior of British America. The southern Appalachian tree is called she balsam and she balsam fir. These names have no scientific basis, and they appear to have originated in a desire to distinguish this tree from the red spruce with which it is associated. The spruce is called “he balsam.” Artificial names like these are not necessary to distinguish red spruce from Fraser fir, as very slight acquaintance should enable anybody to tell one from the other at sight, and to see clearly that they are not of the same species. Mountain balsam, a North Carolina name for this fir, is well taken, for it is distinctly a mountain species. The name healing balsam is given in acknowledgment of the supposed medicinal properties of the resin which collects in blisters or pockets under the bark of young trees and near the tops of old. In West Virginia, where this tree reaches the northern limits of its habitat, it is called blister pine, on account of the resin pockets. In the same region it is called stackpole pine, because farmers who mow mountain meadows use straight, very light poles cut from this fir round which to build haystacks.

This tree is decidedly an inhabitant of the high, exposed localities, being found entirely in the upper elevations of the southern Appalachian mountains, either forming extensive pure stands or growing in the company of red spruce (Picea rubens), with a scattering of various stunted hardwoods, as birch, mountain ash, cherry and usually with an undergrowth of rhododendron.

Fraser fir’s range extends from the high mountains of North Carolina, where it grows 6,000 feet above sea level, northward into West Virginia, within a few miles of the Maryland line, at an altitude of 3,300 feet. The tree is not found in all regions between its northern and southern limits. Its best development is in the southern part of its range.

On the upper limits of its habitat the tree presents a decidedly picturesque appearance, being gnarled and twisted and plainly showing the results of its long struggle for life and development. It is always noticeable that on the exposed side the limbs are so short as to be almost missing and on the opposite side they grow out straight and long, appearing to fly before the wind. These limbs are sometimes of as great a girth for five or six feet of their length as any part of the main stem, and have a singular look, seeming to be all out of proportion to the rest of the tree. The older trees are vested in a smooth, yellowish-gray, mossy bark, which is quite different from that of the balsam fir. The bark is thin, about one-fourth of an inch on young trunks, and half an inch near the ground on old ones. The leaves are usually half an inch long, sometimes one inch, and their lower sides are whitish, which tint is due to abundant white stomata. In that respect they resemble leaves of balsam fir and hemlock.

The cones, like those of other species of fir, stand erect on the branches, and average about two and a half inches in length. They are smoother than the cones of most pines. They mature in September. The winged seeds average one-eighth inch in length, and are fairly abundant. The Fraser fir grows as tall as balsam fir, from forty to sixty feet, and the trunk diameter is greater, being sometimes thirty inches, though half of that is nearer an average. When of pole size, that is, from five to eight inches in diameter, Fraser fir is often tall, straight and shapely. Its form, however, depends upon the situation in which it grows. If in the open, it develops a relatively short trunk and a broad, pyramidal crown. This fir differs from balsam fir in its choice of situation. The latter, though not exactly a swamp tree, prefers damp ground, while Fraser fir flourishes on slopes and mountain tops.

On the mountains of western North Carolina fir grows in mixture with red spruce. Sometimes the fir is fifty per cent of the stand, but usually it is less, and frequently not more than fifteen per cent. Few fir trees in that locality are two feet in diameter. They grow with fair rapidity in their early years, but decline in rate as age comes on. It may be observed in traveling through the stands of mixed spruce and fir among the high ranges of the southern Appalachian mountains that the proportion of spruce is much higher in old stands than in young. That is due to the greater age to which spruce lives. Trees of that species continue to stand after the firs have died of old age. On the other hand, fir outnumbers spruce in many young stands. That is because fir reproduces better than spruce, and grows with more vigor at first. In stands of second growth the fir often predominates. It depends to some extent upon the conditions under which the second growth has its start. Fir does not germinate well if the ground has been bared by fire and the humus burned. Consequently, old burns do not readily grow up in fir. The best stands occur where the natural conditions have not been much disturbed further than by removing the growth. Fortunately conditions on the summit and elevated slopes of the southern Appalachians do not favor destructive forest fires. Rain is frequent and abundant, and the shade cast by evergreen trees keeps the humus too moist for fire. To this condition is due the comparative immunity from fire of the high mountain forests of fir and spruce. Sometimes, however, fires sweep through fine stands with disastrous results. The destruction is more serious because no second forest of evergreens is likely on tracts which have been severely burned.

A report by the State Geological Survey on forest conditions in western North Carolina, issued in 1911, predicted that spruce and fir forests aggregating from 100,000 to 150,000 acres among the high mountain ranges, will become barren tracts, because of the destructive effect of fires stripping the ground of humus.

The cutters of pulpwood in the southern Appalachian mountains take Fraser fir wherever they find it, mix it with spruce, and the two woods go to market as one. Statistics show the annual cut of both, but do not give them separately. The output of spruce, including fir, south of Pennsylvania, in 1910 was 115,993 cords, equivalent to about 80,000,000 feet, board measure. Most of it was red spruce, but some was fir, and in North Carolina probably twenty-five per cent was of that species. The total pulpwood cut in that state was 14,509 cords of the two woods combined, and probably 3,800 cords were Fraser fir.

The wood of Fraser fir is very light. An air dry sample from Roan mountain, N. C., weighed 22.22 pounds per cubic foot. That is lighter than balsam fir, which is classed among the very light woods. It is stronger than balsam fir by twenty-five per cent. The wood is soft, compact and the bands of summerwood in the annual rings are rather broad and light colored and are not conspicuous. The medullary rays are thin but numerous. The color is light brown, the sapwood mostly white.

This wood is not of much commercial value except for pulp. It is not abundant, and it is not suited to many purposes. It is suitable for boxes, being light in weight and moderately strong; but other woods which grow in the same region are as good in all respects and are more abundant, and will be used in preference to fir for that purpose. The decrease in area on account of fires, and in quantity because of pulpwood operations, indicates that forest grown Fraser fir has seen its best days. On the other hand, the United States Forest Service has acquired tracts of land on the summits of the mountains where this species has its natural home, and the growth will be protected from fires and from destructive cutting, and there is no danger that the species will be exterminated.
