Part 6
At an early date Norway pine from Canada and northern New York was popular ship timber in this country and England. Slender, straight trunks were selected as masts, or were sawed for decking planks thirty or forty feet long. Shipbuilders insisted that planks be all heartwood, because when sapwood was exposed to rain and sun, it changed to a green color, due to the presence of fungus. The wood wears well as ship decking. The British navy was still using some Norway pine masts as late as 1875.
The scarcity of this timber has retired it from some of the places which it once filled, and the southern yellow pines have been substituted. It is still employed for many important purposes, the chief of which is car building, if statistics for the state of Illinois are a criterion for the whole country. In 1909 in that state 24,794,000 feet of it were used for all purposes, and 14,783,000 feet in car construction.
For many years Chicago has been the center of the Norway pine trade. It is landed there by lake steamers and by rail, and is distributed to ultimate consumers. The uses for the wood, as reported by Illinois manufacturers, follow: Baskets, boxes, boats, brackets, casing and frames for doors and windows, crating, derricks for well-boring machines, doors, elevators, fixtures for stores and offices, foot or running boards for tank cars, foundry flasks, freight cars, hand rails, insulation for refrigerator cars, ladders, picture moldings, roofing, sash, siding for cattle cars, sign boards and advertising signs, tanks, and windmill towers.
As with white pine, Norway pine has passed the period of greatest production, though much still goes to market every year and will long continue to do so. The land which lumbermen denuded in the Lake States,
## particularly Michigan and Wisconsin, years ago, did not reclothe itself
with Norway seedlings. That would have taken place in most instances but for fires which ran periodically through the slashings until all seedlings were destroyed. In many places there are now few seedlings and few large trees to bear seeds, and consequently the pine forest in such places is a thing of the past. The outlook is better in other localities.
The Norway pine is much planted for ornament, and is rated one of the handsomest of northern park trees.
PITCH PINE (_Pinus rigida_). The name pitch pine is locally applied to almost every species of hard, resinous pine in this country. The _Pinus rigida_ has other names than pitch pine. In Delaware it is called longleaved pine, since its needles are longer than the scrub pine’s with which it is associated. For the same reason it is known in some localities as longschat pine. In Massachusetts it is called hard pine, in Pennsylvania yellow pine, in North Carolina and eastern Tennessee black pine, and black Norway pine in New York. The botanical name is translated “rigid pine,” but the rigid refers to the leaves, not the wood. Its range covers New England, New York, Pennsylvania, southern Canada, eastern Ohio, and southward along the mountains to northern Georgia. It has three leaves in a cluster, from three to five inches long, and they fall the second year. Cones range in length from one to three inches, and they hang on the branches ten or twelve years. The wood is medium light, moderately strong, but low in stiffness. It is soft and brittle. The annual rings are wide, the summerwood broad, distinct, and very resinous. Medullary rays are few but prominent; color, light brown or red, the thick sapwood yellow or often nearly white. The difference in the hardness between springwood and summerwood renders it difficult to work, and causes uneven wear when used as flooring. It is fairly durable in contact with the soil.
The tree attains a height of from forty to eighty feet and a diameter of three. This pine is not found in extensive forests, but in scattered patches, nearly always on poor soil where other trees will not crowd it. Light and air are necessary to its existence. If it receives these, it will fight successfully against adversities which would be fatal to many other species. In resistance to forest fires, it is a salamander among trees. That is primarily due to its thick bark, but it is favored also by the situations in which it is generally found--open woods, and on soil so poor that ground litter is thin. It is a useful wood for many purposes, and wherever it is found in sufficient quantity, it goes to market, but under its own name only in restricted localities. Its resinous knots were once used in place of candles in frontier homes. Tar made locally from its rich wood was the pioneer wagoner’s axle grease, and the ever-present tar bucket and tar paddle swung from the rear axle. Torches made by tying splinters in bundles answered for lanterns in night travel. It was the best pine for floors in some localities. It is probably used more for boxes than for anything else at present. In 1909 Massachusetts box makers bought 600,000 feet, and a little more went to Maryland box factories. Its poor holding power on spikes limits its employment as railroad ties and in shipbuilding. Carpenters and furniture makers object to the numerous knots. Country blacksmiths who repair and make wagons as a side line, find it suitable for wagon beds. It is much used as fuel where it is convenient.
TORREY PINE (_Pinus torreyana_), called del mar pine and Soledad pine, is an interesting tree from the fact that its range is so restricted that the actual number of trees could be easily known to one who would take the trouble to count them. A rather large quantity formerly occupied a small area in San Diego county, California, but woodchoppers who did not appreciate the fact that they were exterminating a species of pine from the face of the earth, cut nearly all of the trees for fuel. Its range covered only a few square miles, and fortunately part of that was included in the city limits of San Diego. An ordinance was passed prohibiting the cutting of a Torrey pine under heavy penalty, and the tree was thus saved. A hundred and fifty miles off the San Diego coast a few Torrey pines grow on the islands of Santa Cruz and Santa Rosa, and owing to their isolated situation they bid fair to escape the cordwood cutter for years to come. Those who have seen this tree on its native hills have admired the gameness of its battle for existence against the elements. Standing in the full sweep of the ocean winds, its strong, short branches scarcely move, and all the agitation is in the thick tufts of needles which cling to the ends of the branches. Trees exposed to the seawinds are stunted, and are generally less than a foot in diameter and thirty feet high; but those which are so fortunate as to occupy sheltered valleys are three or four times that size. The needles are five in a cluster. The cones persist on the branches three or four years. The wood is light, soft, moderately strong, very brittle; the rings of yearly growth are broad, and the yellow bands of summerwood occupy nearly half. The sapwood is very thick and is nearly white.

WESTERN YELLOW PINE
[Illustration: WESTERN YELLOW PINE]
WESTERN YELLOW PINE
(_Pinus Ponderosa_)
The range of western yellow pine covers a million square miles. Its eastern boundary is a line drawn from South Dakota to western Texas. The species covers much of the country between that line and the Pacific ocean. It is natural that it should have more names than one in a region so extensive. It is best known as western yellow pine, but lumbermen often call it California white pine. The standing timber is frequently designated bull pine, but that name is not often given to the lumber. Where there is no likelihood of confusing it with southern pines, it is called simply yellow pine. The name heavy-wooded pine, sometimes applied to the lumber in England, is misleading. When well seasoned it weighs about thirty pounds per cubic foot, and ordinarily it would not be classed heavy. In California it is called heavy pine, but that is to distinguish it from sugar pine which is considerably lighter. The color of its bark has given it the name Sierra brownbark pine. The same tree in Montana is called black pine.
The tree has developed two forms. Some botanists have held there are two species, but that is not the general opinion. In the warm, damp climate of the Pacific slope the tree is larger, and somewhat different in appearance from the form in the Rocky Mountain region. The same observation holds true of Douglas fir.
The wood of western yellow pine is medium light, not strong, is low in elasticity, medullary rays prominent but not numerous; resinous, color light to reddish, the thick sapwood almost white. The annual rings are variable in width, and the proportionate amounts of springwood and summerwood also vary. It is not durable in contact with the ground.
The wood is easy to work and some of the best of it resembles white pine, but as a whole it is inferior to that wood, though it is extensively employed as a substitute for it in the manufacture of doors, sash, and frames. It is darker than white pine, harder, heavier, stronger, almost exactly equal in stiffness, but the annual rings of the two woods do not bear close resemblance.
The tree reaches a height of from 100 to 200 feet, a diameter from three to seven. It is occasionally much larger. Its size depends much on its habitat. The best development occurs on the Sierra Nevada mountains in California and the best wood comes from that region, though certain other localities produce high-grade lumber.
Western yellow pine holds and will long hold an important place in the country’s timber resources. The total stand has been estimated at 275,000,000,000 feet, and is second only to that of Douglas fir, though the combined stand of the four southern yellow pines is about 100,000,000,000 feet larger. It is a vigorous species, able to hold its ground under ordinary circumstances. Next to incense cedar and the giant sequoias which are associated with it in the Sierra Nevada mountains, it is the most prolific seed bearer of the western conifers, and its seeds are sufficiently light to insure wide distribution. It is gaining ground within its range by taking possession of vacant areas which have been bared by lumbering or fire. In some cases it crowds to death the more stately sugar pine by cutting off its light and moisture. It resists fire better than most of the forest trees with which it is associated. On the other hand, it suffers from enemies more than its associates do. A beetle (_Dendroctonus ponderosæ_), destroys large stands. In the Black Hills in 1903 its ravages killed 600,000,000 feet.
This splendid pine has run the gamut of uses from the corral pole of the first settler to the paneled door turned out by the modern factory. It has almost an unlimited capacity for usefulness. It grows in dry regions of the Rocky Mountains where it is practically the only source of wood supply; and it is equally secure in its position where forests are abundant and fine. It has supplied props, stulls, and lagging for mines in nearly every state touched by its range. Without its ties and other timbers some of the early railroads through the western mountains could scarcely have been built. It has been one of the leading flume timbers in western lumber and irrigation development. It fenced many ranches in early times and is still doing so. It is used in general construction, and in finish; from the shingle to the foundation sill of houses. It finds its way to eastern lumber markets. Almost 20,000,000 feet a year are used in Illinois alone. Competition with eastern white pine is met in the Lake States because, grade for grade, the western wood is cheaper, until lower grades are reached. The western yellow pine, in the eastern market, is confused with the western white pine of Idaho and Montana (_Pinus monticola_) and separate statistics of use are impossible.
The makers of fruit boxes in California often employ the yellow pine in lieu of sugar pine which once supplied the whole trade. It is also used by coopers for various containers, but not for alcoholic liquors.
The leaves are in clusters of twos and threes, and are from five to eleven inches long. Most of them fall during the third year. The cones are from three to six inches long, and generally fall soon after they reach maturity.
COULTER PINE (_Pinus coulteri_) is also known as nut pine, big cone pine, and long cone pine. It is a California species, scarce, but of much interest because of its cones. They are larger than those of any other American pine and are armed with formidable curved spines from half an inch to an inch and a half in length. The cones are from ten to fourteen inches long. The tree is found on the Coast Range mountains from the latitude of San Francisco to the boundary between California and Mexico. It thrives at altitudes of from 3,000 to 6,000 feet. It never occurs in pure stands and the total amount is small. It looks like the western yellow pine, but is much inferior in size. Trunks seldom attain a length of fifteen feet or a diameter of two. There is no evidence that Coulter pine is increasing its stand on the ground which it already occupies, or spreading to new ground. The wood is light, soft, moderately strong, and very tough. The annual rings are narrow and consist largely of summerwood. The heartwood is light red, the thick sapwood nearly white. It is a poor tree for lumber, and it has been little used in that way, but has been burned for charcoal for blacksmith shops, and much is sold as cordwood. The leaves of Coulter pine are in clusters of three, and they fall during the third and fourth years.
CALIFORNIA SWAMP PINE (_Pinus muricata_) clearly belongs among minor species listed as timber trees. It meets a small demand for skids, corduroy log roads, bridge floors, and scaffolds in the redwood logging operations in California. It is scattered along the Pacific coast 500 miles, beginning in Lower California and ending a hundred miles north of San Francisco. It is known as dwarf marine pine, pricklecone pine, bishop pine, and obispo pine. The last name is the Spanish translation of the English word bishop. The largest trees seldom exceed two feet in diameter, and a height of ninety feet. The average size is little more than half as much. The wood is very strong, hard, and compact, and the annual growth ring is largely dense summerwood. Resin passages are few, but the wood is resinous, light brown in color, and the thick sapwood is nearly white. The needles are in clusters of two, and are from four to six inches long. They begin to fall the second year. Some of the trees retain their cones until death, but the seeds are scattered from year to year. Under the stimulus of artificial conditions in the redwood districts this pine seems to be spreading. Its seeds blow into vacant ground from which redwood has been removed, and growth is prompt. The seedlings are not at all choice as to soil, but take root in cold clay, in peat bogs, on barren sand and gravel, and on wind-swept ridges exposed to ocean fogs. Its ability to grow where few other trees can maintain themselves holds out some hope that its usefulness will increase.
MONTEREY PINE (_Pinus radiata_). This scarce and local species is restricted to the California coast south of San Francisco, and to adjacent islands. Under favorable circumstances it grows rapidly and promises to be of more importance as a lumber source in the future than it has been in the past. It is, however, somewhat particular as to soil. It must have ground not too wet or too dry. If these requirements are observed, it is a good tree for planting. Its average height is seventy or ninety feet, diameter from eighteen to thirty inches. Trunks six feet in diameter are occasionally heard of. The wood is light, soft, moderately strong, tough, annual rings very wide and largely of springwood; color, light brown, the very thick sapwood nearly white. The leaves are from four to six inches long, in clusters of two and three, and fall the third year. Cones are from three to five inches long. The lumber is too scarce at present to have much importance, but its quality is good. In appearance it resembles wide-ringed loblolly pine, and appears to be suitable for doors and sash, and frames for windows and doors. Its present uses are confined chiefly to ranch timbers and fuel. If it ever amounts to much as a lumber resource, it will be as a planted pine, and not in its natural state.
JACK PINE (_Pinus divaricata_) is a far northern species which extends its range southward in the United States, from Maine to Minnesota, and reaches northern Indiana and Illinois. It grows almost far enough north in the valley of Mackenzie river to catch the rays of the midnight sun. It must necessarily adapt itself to circumstances. When these are favorable, it develops a trunk up to two feet in diameter and seventy feet tall; but in adversity, it degenerates into a many-branched shrub a few feet high. The average tree in the United States is thirty or forty feet tall, and a foot or more in diameter. Its name is intended as a term of contempt, which it does not deserve. Others call it scrub pine which is little better. Its other names are more respectful, Prince’s pine in Ontario, black pine in Wisconsin and Minnesota, cypress in Quebec and the Hudson Bay country, Sir Joseph Banks’ pine in England, and juniper in some parts of Canada. “Chek pine” is frequently given in its list of names, but the name is said to have originated in an attempt of a German botanist to pronounce “Jack pine” in dictating to a stenographer. The tree straggles over landscapes which otherwise would be treeless. It is often a ragged and uncouth specimen of the vegetable kingdom, but that is when it is at its worst. At its best, as it may be seen where cared for in some of the Michigan cemeteries, it is as handsome a tree as anyone could desire. The characteristic thinness and delicacy of its foliage distinguish it at once from its associates. The peculiar green of its soft, short needles wins admiration. The wood is light, soft, not strong; annual rings are moderately wide, and are largely composed of springwood. The thin bands of summerwood are resinous, and the small resin ducts are few. The thick sapwood is nearly white, the heartwood brown or orange. It is not durable.
Jack pine can never be an important timber tree, because too small; but a considerable amount is used for bed slats, nail kegs, plastering lath, barrel headings, boxes, mine props, pulpwood, and fuel. Aside from its use as lumber and small manufactured products, it has a value for other purposes. It can maintain its existence in waste sands; and its usefulness is apparent in fixing drifting dunes along some of the exposed shores of Lake Michigan and Lake Superior. It lives on dry sand and sends its roots several feet to water; or, under circumstances entirely different, it thrives in swamps where the watertable is little below the surface of the ground. It fights a brave battle against adversities while it lasts, but it does not live long. Sixty years is old age for this tree. It grows fast while young, but later it devotes all its energies to the mere process of living, and its increase in size is slow, until at a period when most trees are still in early youth, it dies of old age, and the northern winds quickly whip away its limbs, leaving the barkless trunk to stand a few years longer.

LODGEPOLE PINE
[Illustration: LODGEPOLE PINE]
LODGEPOLE PINE
(_Pinus Contorta_)
The common name of this tree was given it because its tall, slender, very light poles were used by Indians of the region in the construction of their lodges. They selected poles fifteen feet long and two inches in diameter, set them in a circle, bent the tops together, tied them, and covered the frame with skins or bark. The poles were peeled in early summer, when the Indians set out upon their summer hunt, and were left to season until fall, when they were carried to the winter’s camping place, probably fifty miles distant. Tamarack is a common name for this pine in much of its range; it is likewise known as black pine, spruce pine, and prickly pine. Its leaves are from one to two inches long, in clusters of two. The small cones adhere to the branches many years--sometimes as long as twenty--without releasing the seeds, which are sealed within the cone by accumulated resin. The vitality of the seeds is remarkable. They don’t lose their power of germination during their long imprisonment.
The lodgepole pine has been called a fire tree, and the name is not inappropriate. It profits by severe burning, as some other trees of the United States do, such as paper birch and bird cherry. The sealed cones are opened by fire, which softens the resin, and the seeds are liberated after the fire has passed, and wing their flight wherever the wind carries them. The passing fire may be severe enough to kill the parent tree without destroying or bringing down the cones. The seeds soon fall on the bared mineral soil, where they germinate by thousands. More than one hundred thousand small seedling trees may occupy a single acre. Most of them are ultimately crowded to death, but a thick stand results. Most lodgepole pine forests occupy old burns. The tree is one of the slowest of growers. It never reaches large size--possibly three feet is the limit. It is very tall and slender. A hundred years will scarcely produce a sawlog of the smallest size.
The range of this tree covers a million square miles from Alaska to New Mexico, and to the Pacific coast. Its characters vary in different parts of its range. A scrub form was once thought to be a different species, and was called shore pine.
The wood is of about the same weight as eastern white pine. It is light in color, rather weak, and brittle, annual rings very narrow, summerwood small in amount, resin passages few and small; medullary rays numerous, broad, and prominent. The wood is characterized by numerous small knots. It is not durable in contact with the ground, but it readily receives preservative treatment. In height it ranges from fifty to one hundred feet.
The government’s estimate of the stand of lodgepole pine in the United States in 1909 placed it at 90,000,000,000 feet. That makes it seventh in quantity among the timber trees of this country, those above it being Douglas fir, the southern yellow pines (considered as one), western yellow pine, redwood, western hemlock, and the red cedar of Washington, Oregon, and Idaho.
