Chapter II: Part 2

Beautiful trees are these spruces and firs, either in the forest or when brought by the planter to his home grounds. The leaves are much shorter than those of most pines, and clothe the twigs closely. There is a vast variety in color, too, from the wonderful whitish or "glaucous" blue of the Colorado blue spruce, to the deep shining green of Nordmann's fir, a splendid introduction from the Caucasus. Look at them, glistening in the winter sun, or drooping with the clinging snow; walk in a spruce wood, inhaling the bracing balsamic fragrance which seems so kindly to the lungs; hark to the music of the wind in their tops, telling of health and purity, of God's love and provision for man's mind and heart, and you will begin to know the song of the firs. To really hear this grand symphony, for such it then becomes, you must listen to the wind playing on the tops of a great primeval coniferous forest, of scores and hundreds of acres or miles in extent. And even then, many visits are needed, for there are movements to this symphony--the allegro of the gale, the scherzo of the easy morning breeze, the deep adagio of a rain-storm, and the andante of warm days and summer breezes, when you may repose prone upon a soft carpet of pine needles, every sense made alert, yet soothed, by the master-theme you are hearing.

There is a little wood of thick young pines, interspersed with hard maple and an occasional birch, close by the lake of the Eagles, where my summers are made happy. The closeness of the pines has caused their lower branches to die, as always in the deep forest, and the falling needles, year by year, have deepened the soft brown carpet that covers the forest floor. Some one, years ago, struck by the aisles that the straight trunks mark out so clearly, called this the "Cathedral Woods." The name seems appropriate at all times, but especially when, on a warm Sunday afternoon, I lie at ease on the aromatic carpet, hearing the soft organ tones in the pine tops, and drinking in God's forest message.

I have visited these pine woods at midnight, when a full moon, making brilliant the near-by lake, gave but a ghostly gloom in the deep, deep silence of the Cathedral; but, more impressive, I have often trodden through in a white fog, when the distance was misty and dim, and the aisles seemed longer and higher, and to lead one further away from the trifles of temper and trial. Indeed, I do not believe that any one who has but once fully received from the deep forest that which it gives out so freely and constantly can ever think of things trivial, or of minor annoyances, while again within its soothing portals.

But of the trees of the forest of pine and spruce it must be noted that sometimes the deepest, glossiest green of the leaves as presented to the eye only hides the dainty, white-lined interior surface of those same leaves. To the outside, a somber dignity, unassailable, untouched by frost or sun, protective, defenseful, as nature often appears to the careless observer; but inside is light, softly reflected, revealing unsuspected delicacies of structure and finish.

To us who are not woodsmen or "timber-cruisers" the most familiar of all the spruces is the introduced form from Norway. Its yellowish green twigs are bright and cheerful, and in specimens that have reached the fruiting age the crown of cones, high up in the tree, is an additional charm, for these soft brown "strobiles," as the botanist calls them, are smooth and regular, and very different from those of the rugged pines. I have often been told that the Norway spruce was short-lived, and that it became unkempt in age; but now that I have lived for ten years and more beside a noble specimen, I know that the change from the upreaching push of youth to the semi-drooping sedateness of maturity is only a taking on of dignity. There stands on the home grounds of a true tree-lover in Pennsylvania a Norway spruce that has been untouched by knife or disaster since its planting many years ago. No pruning has shortened in its "leader" or top, no foolish idea of "trimming it up" has been allowed to deprive it of the very lowest branches, which, in consequence, now sweep the ground in full perfection, while the unchecked point of the tree still aspires upward forty feet above. A beautiful object is this tree--perhaps the most beautiful of all the conifers in my friend's great "pinetum," with its scores of rare species. Let me ask, then, those who would set this or any other tree of evergreen about the home, to see to it that the young tree from the nursery has all its lower branches intact, and that its top has never been mutilated. With care, such specimens may be obtained and successfully transplanted, and will grow in time to a lovely old age of steady greenness.

The balsam fir is almost indistinguishable from the Norway spruce when young, but soon grows apart from it in habit, and is hardly as desirable, even though a native. It is rich in the true balsamic odor; and this, again, is its destruction; for one "spruce pillow" may destroy a half dozen trees!

The white cedar, our common juniper, with its aromatic blue berries or fruits, is perhaps the most familiar of all the native evergreens. It comes to us of Pennsylvania all too freely at Christmas time, when the tree of joy and gifts may mean, in the wholesale, sad forest destruction. This juniper I have associated particularly with the dogwood and the red-bud, to the bloom of which it supplies a most perfect background in the favorite Conewago park, a purely natural reservation of things beautiful along the Pennsylvania railroad. Its lead-pencil sister, the red cedar, reaches our literary senses as closely as does the pulp-making spruce!

I might write much of the rare introduced cypresses from Japan and China, and of the peculiar variations that have been worked out by the nurserymen among the native pines and firs; yet this would not be talk of the trees of the open ground, but rather of the nursery and the park. Also, if I had but seen them, there would be much to say about the magnificent conifers of the great West, from the giant red-woods, or sequoias, of the Mariposa grove in California to the richly varied pines of the Rockies. But I can only suggest to my readers the intimate consideration of all this great pine family, so peculiarly valuable to mankind, and the use of some of the pines and spruces about the home for the steady cheer of green they so fully provide.

Apples

Well do I remember one of the admonitions of my youth, brought upon me by an attempt to take apple-blossoms from a tree in bloom because they were beautiful. I was told that it was wrong to pluck for any purpose the flowers of fruit trees, because the possible fruitage might thereby be reduced. That is, feeding the eye was improper, but it was always in order to conserve all the possibilities for another organ of the body. In those days we had not learned that nature provides against contingencies, and that not one-tenth of all the blossoms would be needed to "set" as much fruit as the tree could possibly mature.

The apple, well called the king of fruits, is worthy of all admiration as a fruit; but I do not see why that need interfere in the least with its consideration as an object of beauty. On the contrary, such consideration is all the better for the apple, which is not only most desirable and pleasing in its relation to the dessert, the truly celebrated American pie, the luscious dumpling of the housewife, and the Italian's fruit-stand of our cities, but is at the same time a benefaction to the eye and the sense of beauty, in tree, in blossom, and in fruit.

It is of the esthetic value of the apple I would write, leaving its supreme place in pomology unassailed. Look at the young apple tree in the "nursery row," where it has been growing a year since it was "budded"--that is, mysteriously changed from the wild and untamed fruit of nature to the special variety designed by the nurseryman. It is a straight, shapely wand, in most varieties, though it is curious to find that some apples, notably the favorite Rhode Island Greening, start in promptly to be picturesquely crooked and twisty. As it grows and branches under the cultivation and guidance of the orchardist, it maintains a lusty, hearty aspect, its yellowish, reddish or brownish twigs--again according to variety--spreading out to the sun and the air freely. A decade passes, and the sparse showing of bloom that has decorated it each spring gradually gives place to a great glory of flowers. The tree is about to bear, and it assumes the character of maturity; for while it grows on soberly for many years, there is now a spreading, a sort of relaxation, very different from the vigorous upshooting of its early youth. After a crop or two, the tree has become, to the eye, the familiar orchard member, and it leans a little from the blasts of winter, twists aside from the perpendicular, spreads comfortably over a great expanse of ground, and settles down to its long, useful, and truly beautiful life.

While the young orchard is trim and handsome, I confess to a greater liking for the rugged old trees that have followed blossom with fruit in unstinted profusion for a generation. There is a certain character of sturdy good-will about these substantial stems that the clinging snows only accentuate in winter. The framework of limb and twig is very different from that of the other trees, and the twisty lines seem to mean warmth and cheer, even against a frosty sky. And these old veterans are house trees, too--they do not suggest the forest or the broad expanse of nature, but, instead, the proximity of man and the home, the comfortable summer afternoon under their copious leafage, the great piles of ruddy-cheeked fruit in autumn.

I need hardly say anything of the apple-blossoms, for those who read these words are almost certain to have long appreciated their delicately fragrant blush and white loveliness. The apricot and the cherry are the first of the fruit trees to sing the spring song, and they cover themselves with white, in advance of any sign of green leaves on their twigs. The apple has an advantage; coming more deliberately, the little pink buds are set amidst the soft greens of the opening foliage, and the leaves and flowers expand together in their symphony of color and fragrance. The grass has grown lush by this time, the dandelions are punctuating it with gold, and everything is in the full riot of exuberant springtime.

But there are apples and apples and apples. Even the plain orchard gives us a difference in flowers, as well as in tree aspect. Notice the trees this coming May; mark the flat, white flowers on one tree, the cup-shaped, pink-veined blooms on another. Follow both through the fruiting, and see whether the sweeter flower brings the more sugary fruit. This fact ascertained, perhaps it may be followed up by observation of the distinctive color of the twigs and young branches--for there are wide differences in this respect, and the canny tree-grower knows his pets afar.

Perhaps there is a "crab" in the old orchard, ready to give the greatest burst of bloom--for the crab-apple flower is usually finer and more fragrant than any other of the cultivated forms. It is an especial refuge of the birds and the bees, you will find, and it invites them with its rare fragrance and deeper blush, so that they may work all the more earnestly at the pollination without which all this richness of bloom would be ineffective in nature's reproductive scheme.

This same crab-apple is soon to be, as its brilliant fruit matures, a notable object of beauty, for few ornamental trees can vie with its display of shining color. There was a great old crab right in the flower garden of my boyhood home, amid quaint box-trees, snowballs and lilacs. Lilies-of-the-valley flourished in its shadow, the delicate bleeding-heart mingled with old-fashioned irises and peonies at its feet. From early spring until mid-August the crab-apple held court of beauty there--and an always hungry boy often found something in addition to beauty in the red and yellow fruits that were acid but aromatic.

With a little attention, if one would plant crab-apples for their loveliness of fruit hue and form, a fine contrast of color may be had; for some varieties are perfect in clear yellow, against others in deepest scarlet, bloom-covered with blue haze, and yet others which carry all the colors from cream to crimson--the latter as the warm sun paints deeper.

Why do we not plant more fruit trees for beauty? Not one of our familiar fruits will fail us in this respect, if so considered. The apricot will often have its white flowers open to match the purity of the last snow, the cherry will follow with a burst of bloom, the apples and crab-apples will continue the show, aided by plum and pear and peach, and the quince--ah, there's a flower in a green enamel setting!--will close the blooming-time. But the cherry fruits now redden in shining roundness, the earlier apples throw rich gleams of color to the eye, and there is chromatic beauty until frost bids the last russets leave their stems, leaving bare the framework of the trees, to teach us in lines of symmetry and efficiency how strength and elegance are combined in nature's handiwork. Do you fear that some of the fruit may be taken? What of it? Plant for beauty, and the fruit is all extra--give it away freely, and pass on to others some of God's good gifts, to your own true happiness!

There is another crab-apple that is distinctive in its elegance, color and fragrance. It is the true "wild crab" of Eastern North America, and one who makes its acquaintance in blooming time will never forget it. The tree is not large, and it is likely to be set with crooked, thorny branches; but the flowers! Deep pink or rosy red chalices, rather longer than the commonplace apple-blossom, and hanging on long and slender stems in a certain picturesquely stiff disposition, they are a joy for the senses of sight and fragrance. This notable native may be found on rich slopes and in dry glades--it is not fond of swamps. It is grown by some enlightened nurserymen, too, and can well be planted in the home grounds to their true adornment. The blossoms give way to form handsome yellow fruits, about an inch in diameter, which are themselves much more ornamental than edible, for even the small boy will not investigate a second time the bitter flesh. I have heard that a cider of peculiar "hardness" and potency, guaranteed to unsettle the firmest head, is made from these acid fruits--but I have not found it necessary to extend my tree studies in that direction.

The states west of Kansas do not know this lovely wild crab, to which the botanists give a really euphonious designation as _Pyrus coronaria_. There is a prairie-states crab-apple, which I have never seen, but which, I am told, has nothing like the beauty of our exquisite Eastern native. This Western species lacks the long stem and the bright color of the flowers of our favorite, and its fruits, while quite as viciously sour, are a dull and greasy green. The great West has many other things, but we have the wild crab-apple.

Rather between, as to beauty, is the native crab-apple of the Southland, which is known as the Soulard crab. It is not as attractive as our own Eastern gem, a pure native possession, and one which our foreign friends envy us.

Curiously enough, our own fruiting apple is not a native of America. It was at a meeting of a New England pomological association that I heard, several years ago, an old man of marvelous memory and power of observation tell of his recollections of seventy years, notable among which was his account of seeing the first good apples, as a boy, during a visit in the state of New York. Think of it! the most widely grown and beautiful of all our fruits hardly older than the railroad in America! We owe the apples we eat to Europe, for the start, the species being probably of Himalayan origin. America has greatly developed the apple, however, as one who has looked over the fruit tables at any great exposition will promptly testify, and nearly all our really good varieties are of American origin. Moreover, we are the greatest apple-growers in the world, and the yearly production probably exceeds a hundred millions of barrels.

The curious story of "Johnny Appleseed" is given us by historians, who tell us of this semi-religious enthusiast who roamed barefoot over the wilds of Ohio and Indiana a century ago, sowing apple-seeds in the scattered clearings, and living to see the trees bearing fruit, selections from which probably are interwoven among the varieties of today. New varieties of apples, by the way, come from seeds sown, and trees grown from them, with a bare chance that one in ten thousand may be worth keeping. When a variety seems thus worthy, "buds" or "scions" from the original tree are "budded" or "grafted" by the nurseryman into young seedling trees, which are thus changed into the selected sort. To sow the seeds of your favorite Baldwin does not imply that you will get Baldwin trees, by any means; you will more likely have a partial reversion to the acid and bitter original species.

It is not only for the fruit that we are indebted to the Old World, but also for some distinctively beautiful and most ornamental varieties of the apple, not by any means as well known among us as they ought to be. The nurserymen sell as an ornamental small tree a form known as "Parkman's double-flowering crab," which produces blooms of much beauty, like delicate little roses. Few of them, however, know of the glorious show that the spring brings where there is a proper planting of the Chinese and Japanese crab-apples, with some other hybrids and varieties. To readers in New England a pilgrimage to Boston is always in order. In the Public Gardens are superb specimens of these crab-apples from the Orient, as well as those native to this continent, and for several weeks in May they may be enjoyed. They _are_ enjoyed by the Bostonians, who are in this, as in many things, better served by their authorities than is any other American city. What other city, for instance, gives its people such a magnificent spring show of hyacinths, tulips, daffodils and the like?

It is at the wonderful Arnold Arboretum, that Mecca of tree-lovers just outside of Boston and really within its superbly managed park system, that the greatest show of the "pyrus family," as the apples and pears are botanically called, may be found. Here have been gathered the lovely blooming trees of all the hardy world, to the delight of the eye and the nose, and the education of the mind. To me the most impressive of all was a wonderful Siberian crab (one must look for _Pyrus baccata_ on the label, as the Arboretum folks are not in love with "common" names) close by the little greenhouses. Its round head was purely white, with no hint of pink, and the mass of bloom that covered it was only punctuated by the green of the expanding leaves. The especial elegance of this crab was in its whiteness, and that elegance was not diminished by the later masses of little yellow and red, almost translucent, fruits.

A somewhat smaller tree is commonly called the Chinese flowering apple, and its early flowers remind one strongly of the beauty of our own wild crab, as they are deeper in color than most of the crabs, being almost coral-red in bud. This "spectabilis," as it is familiarly called, is a gem, as it opens the season of the apple blooms with its burst of pink richness.

The beauty-loving Japanese have a festival at the time of the cherry-blooming--and it is altogether a festival of beauty, not connected with the food that follows the flowers. They actually dare to cut the blossoms, too, for adornment, and all the populace take time to drink in the message of the spring. Will we workaday Americans ever dare to "waste" so much time, and go afield to absorb God's provision of soul and sense refreshment in the spring, forgetting for the time our shops and desks, our stores and marts?

Professor Sargent, that deep student of trees who has built himself a monument, which is also a beneficence to all mankind, in the great volumes of his "Silva of North America," lives not far from Boston, and he loves especially that jewel of the apple family which, for want of a common name, I must designate scientifically as _Pyrus floribunda_. On his own magnificent estate, as well as at the Arboretum, this superb shrub or small tree riots in rosy beauty in early spring. While the leaves do come with these flowers, they are actually crowded back out of apparent sight by the straight wands of rose-red blooms, held by the twisty little tree at every angle and in indescribable beauty. If the visitor saw nothing but this Floribunda apple--"abundant flowering" sure enough--on his pilgrimage, he might well be satisfied, especially if he then and there resolved to see it again, either as he planted it at home or journeyed hither another spring for the enlargement of his soul.

There are other of these delightful crabs or apples to be enjoyed--Ringo, Kaido, Toringo--nearly all of Japanese origin, all of distinct beauty, and all continuing that beauty in handsome but inedible fruits that hang most of the summer. My tree-loving friends can well study these, and, I hope, plant them, instead of repeating continually the monotonously familiar shrubs and trees of ordinary commerce.

But I have not spoken enough of one notable feature of the every-day apple tree that we may see without a journey to the East. The fully set fruiting branch of an apple tree in health and vigor, properly nurtured and protected against fungous disease by modern "spraying," is a thing of beauty in its form and color. See those deep red Baldwins shine overhead in the frosty air of early fall; note the elegance of form and striping on the leathery-skinned Ben Davis; appreciate true apples of gold set in green enamel on a tree of the sunny Bellefleur! These in the fall; but it is hardly full summer before the closely set branches of Early Harvest are as beautiful as any orange-tree, or the more upright Red Astrachan is ablaze with fruit of red and yellow. Truly, an apple orchard might be arranged to give a series of pictures of changing beauty of color and growth from early spring until fall frost, and then to follow with a daily panorama of form and line against snow and sky until the blossoms peeped forth again. Let us learn, if we do not already love the apple tree, to love it for its beauty all the year!

Willows and Poplars

"By the rivers of Babylon, there we sat down, yea, we wept, when we remembered Zion. Upon the willows in the midst thereof we hanged our harps." Thus sang the Psalmist of the sorrows of the exiles in Babylon, and his song has fastened the name of the great and wicked city upon one of the most familiar willows, while also making it "weep"; for the common weeping willow is botanically named _Salix Babylonica_.

It may be that the forlorn Jews did hang their harps upon the tree we know as the weeping willow, that species being credited to Asia as a place of origin; but it is open to doubt, for the very obvious reason that the weeping willow is distinctly unadapted to use as a harp-rack, and one is at a loss to know just how the instruments in question would have been hung thereon. It is probable that the willows along the rivers of Babylon were of other species, and that the connection of the city of the captivity and the tears of the exiles with the long, drooping branches of the noble tree which has thus been sorrowfully named was a purely sentimental one. Indeed, the weeping willow is also called Napoleon's willow, because the great Corsican found much pleasure in a superb willow of the same species which stood on the lonely prison isle of St. Helena, and from twigs of which many trees in the United States have been grown.

The willow family presents great contrasts, both physical and sentimental. It is a symbol both of grief and of grace. The former characterization is undoubtedly because of the allusion of the one hundred and thirty-seventh Psalm, as quoted above, thoughtlessly extended through the centuries; and the latter, as when a beautiful and slender woman is said to be of "willowy" form, obviously because of the real grace of the long, swinging wands of the same tree. I might hint that a better reason for making the willow symbolize grief is because charcoal made from its twigs and branches is an important and almost essential ingredient of gunpowder, through which a sufficiency of grief has undoubtedly entered the world!

Willow twigs seem the very essence of fragility, as they break from the parent tree at a touch; and yet one of the willows furnishes the tough, pliable and enduring withes from which are woven the baskets of the world. The willows, usually thin in branch, sparse of somewhat pale foliage, of so-called mournful mien, are yet bursting with vigor and life; indeed, the spread and the value of the family is by reason of this tenacity and virility, which makes a broken twig, floating on the surface of a turbid stream, take root and grow on a sandy bank where nothing else can maintain itself, wresting existence and drawing strength and beauty from the very element whose ravages of flood and current it bravely withstands.

Apparently ephemeral in wood, growing quickly and perishing as quickly, the willows nevertheless supply us with an important preservative element, extracted from their bitter juices. Salicylic acid, made from willow bark, prevents change and arrests decay, and it is an important medical agent as well.

Flexible and seemingly delicate as the little tree is when but just established, there is small promise of the rugged and sturdy trunk that in a few years may stand where the chance twig lodged. And the color of the willows--ah! there's a point for full enthusiasm, for this family of grief furnishes a cheerful note for every month in the year, and runs the whole scale of greens, grays, yellows and browns, and even adds to the winter landscape touches of blazing orange and bright red across the snow. Before ever one has thought seriously of the coming of spring, the long branchlets of the weeping willow have quickened into a hint of lovely yellowish green, and those same branchlets will be holding their green leaves against a wintry blast when most other trees have given up their foliage under the frost's urgency. Often have the orange-yellow twigs of the golden osier illumined a somber countryside for me as I looked from the car window; and close by may be seen other willow bushes of brown, green, gray, and even purple, to add to the color compensation of the season. Then may come into the view, as one flies past, a great old weeping willow rattling its bare twigs in the wind; and, if a stream is passed, there are sure to be seen on its banks the sturdy trunks of the white and the black willows at least. Think of an average landscape with the willows eliminated, and there will appear a great vacancy not readily filled by another tree.

The weeping willow has always made a strong appeal to me, but never one of simple grief or sorrow. Its expression is rather of great dignity, and I remember watching in somewhat of awe one which grew near my childhood's home, as its branches writhed and twisted in a violent rain-storm, seeming then fairly to agonize, so tossed and buffeted were they by the wind. But soon the storm ceased, the sun shone on the rounded head of the willow, turning the raindrops to quickly vanishing diamonds, and the great tree breathed only a gentle and benignant peace. When, in later years, I came to know the moss-hung live-oak of the Southland, the weeping willow assumed to me a new dignity and value in the northern landscape, and I have strongly resented the attitude of a noted writer on "Art Out of Doors" who says of it: "I never once have seen it where it did not hurt the effect of its surroundings, or at least, if it stood apart from other trees, where some tree of another species would not have looked far better." One of the great merits of the tree, its difference of habit, its variation from the ordinary, is thus urged against it.

I have spoken of the basket willow, which is scientifically _Salix viminalis_, and an introduction from Europe, as indeed are many of the family. In my father's nursery grew a great patch of basket willows, annually cut to the ground to make a profusion of "sprouts," from which were cut the "tying willows" used to bind firmly together for shipment bundles of young trees. It was an achievement to be able to take a six-foot withe, and, deftly twisting the tip of it under the heel to a mass of flexible fiber, tie this twisted portion into a substantial loop; and to have this novel wooden rope then endure the utmost pull of a vigorous man, as he braced his feet against the bundle of trees in binding the withe upon it, gave an impression of anything but weakness on the part of the willow.

Who has not admired the soft gray silky buds of the "pussy" willow, swelling with the spring's impulse, and ripening quickly into a "catkin" loaded with golden pollen? Nowadays the shoots of this willow are "forced" into bud by the florists, and sold in the cities in great quantities; but really to see it one must find the low tree or bush by a stream in the woods, or along the roadside, with a chance to note its fullness of blossom. It is finest just when the hepaticas are at their bluest on the warm hillsides; and, one sunny afternoon of a spring journey along the north branch of the Susquehanna river, I did not know which of the two conspicuous ornaments of the deeply wooded bank made me most anxious to jump from the too swiftly moving train.

This pussy-willow has pleasing leaves, and is a truly ornamental shrub or small tree which will flourish quite well in a dry back yard, as I have reason to know. One bright day in February I found a pussy-willow tree, with its deep purple buds showing not a hint of the life within. The few twigs brought home quickly expanded when placed in water, and gave us their forecast of the spring. One twig was, out of curiosity, left in the water after the catkins had faded, merely to see what would happen. It bravely sent forth leaves, while at the base little white rootlets appeared. Its vigor appealing to us, it was planted in an arid spot in our back yard, and it is now, after a year and a half, a handsome, slender young tree that will give us a whole family of silken pussy-buds to stroke and admire another spring.

This same little tree is called also the glaucous willow, and it is botanically _Salix discolor_. It is more distinct than some others of the family, for the willow is a great mixer. The tree expert who will unerringly distinguish between the red oak and the scarlet oak by the precise angle of the spinose margins of the leaves (how I admire an accuracy I do not possess!) will balk at which is crack willow, or white willow, or yellow or blue willow. The abundant vigor and vitality and freedom of the family, and the fact that it is of what is known as the dioecious habit--that is, the flowers are not complete, fertile and infertile flowers being borne on separate trees--make it most ready to hybridize. The pollen of the black willow may fertilize the flower of the white willow, with a result that certainly tends to grayness on the worrying head of the botanist who, in after years, is trying to locate the result of the cross!

There is much variety in the willow flowers--and I wonder how many observers really notice any other willow "blossoms" than those of the showy pussy? A superb spring day afield took me along a fascinatingly crooked stream, the Conodoguinet, whose banks furnish a congenial and as yet protected (because concealed from the flower-hunting vandal) home for wild flowers innumerable and most beautiful, as well as trees that have ripened into maturity. An earlier visit at the time the bluebells were ringing out their silent message on the hillside, in exquisite beauty, with the lavender phlox fairly carpeting the woods, gave a glimpse of some promising willows on the other side of the stream. Twilight and letters to sign--how hateful the desk and its work seem in these days of springing life outside!--made a closer inspection impossible then, but a golden Saturday afternoon found three of us, of like ideals, hastening to this tree and plant paradise. A mass of soft yellow drew us from the highway across a field carpeted thickly with bluet or "quaker lady," to the edge of the stream, where a continuous hum showed that the bees were also attracted. It was one splendid willow in full bloom, and I could not and as yet cannot safely say whether it is the crack willow or the white willow; but I can affirm of a certainty that it was a delight to the eye, the mind and the nostrils. The extreme fragility of the smaller twigs, which broke away from the larger limbs at the lightest shake or jar, gave evidence of one of Nature's ways of distributing plant life; for it seems that these twigs, as I have previously said, part company with the parent tree most readily, float away on the stream, and easily establish themselves on banks and bars, where their tough, interlacing roots soon form an almost impregnable barrier to the onslaught of the flood. Only a stone's throw away there stood a great old black willow, with a sturdy trunk of ebon hue, crowned with a mass of soft green leafage, lighter where the breeze lifted up the under side to the sunlight. Many times, doubtless, the winds had shorn and the sleet had rudely trimmed this old veteran, but there remained full life and vigor, even more attractive than that of youth.

Most of the willows are shrubs rather than trees, and there are endless variations, as I have before remarked. Further, the species belonging at first in the Eastern Hemisphere have spread well over our own side of the globe, so that it seems odd to regard the white willow and the weeping willow as foreigners. At Niagara Falls, in the beautiful park on the American side, on the islands amid the toss of the waters, there are many willows, and those planted by man are no less beautiful than those resulting from Nature's gardening. In spring I have had pleasure in some splendid clumps of a form with lovely golden leaves and a small, furry catkin, found along the edge of the American rapids. I wonder, by the way, how many visitors to Niagara take note of the superb collection of plants and trees there to be seen, and which it is a grateful relief to consider when the mind is wearied with the majesty and the vastness of Nature's forces shown in the cataract? The birds are visitors to Goat Island and the other islets that divide the Niagara River, and they have brought there the plants of America in wonderful variety.

There is one willow that has been used by the nurserymen to produce a so-called weeping form, which, like most of these monstrosities, is not commendable. The goat willow is a vigorous tree introduced from Europe, having large and rather broad and coarse leaves, dark green above and whitish underneath. It is taken as a "stock," upon which, at a convenient height, the skilled juggler with trees grafts a drooping or pendulous form known as the Kilmarnock willow, thus changing the habit of the tree so that it then "weeps" to the ground. Fortunately, the original tree sometimes triumphs, the graft dies, and a lusty goat willow rears a rather shapely head to the sky.

This Kilmarnock willow is a favorite of the peripatetic tree agent, and I have enjoyed hugely one notable evidence of his persuasive eloquence to be seen in a Lebanon Valley town, inhabited by the quaint folk known as Pennsylvania Germans. All along the line of the railroad traversing this valley may be seen these distorted willows decorating the prim front yards, and they are not so offensive when used with other shrubs and trees. In this one instance, however, the tree agent evidently found a customer who was persuaded that if one Kilmarnock willow was a good thing to have, a dozen of them was twelve times better; wherefore his dooryard is grotesquely adorned with that many flourishing weepers, giving an aspect that is anything but decorous or solemn. Some time the vigilance of the citizen will be relaxed, it may be hoped; he will neglect to cut away the recurring shoots of the parent trees, and they will escape and destroy the weeping form which provides so much sarcastic hilarity for the passers-by.

The willow, with its blood relation, the poplar, is often "pollarded," or trimmed for wood, and its abundant vigor enables it to recover from this process of violent abbreviation more satisfactorily than do most trees. The result is usually a disproportionately large stem or bole, for the lopping off of great branches always tends to a thickening of the main stem. The abundant leafage of both willow and poplar soon covers the scars, and there is less cause to mourn than in the case of maples or other "hard-wooded" trees.

If my readers will only add a willow section to their mental observation outfit, there will be much more to see and appreciate. Look for and enjoy in the winter the variation in twig color and bark hue; notice how smoothly lies the covering on one stem, all rugged and marked on another. In the earliest spring examine the swelling buds, of widely differing color and character, from which shortly will spring forth the catkins or aments of bloom, followed by the leaves of varied colors in the varied species, and with shapes as varied. Vivid green, soft gray, greenish yellow; dull surface and shining surface above, pale green to almost pure white beneath; from the long and stringy leaf of the weeping willow to the comparatively broad and thick leaf of the pussy-willow--there is variety and interest in the foliage well worth the attention of the tree-lover. When winter comes, there will be another set of contrasts to see in the way the various species lose their leaves and get ready for the rest time during which the buds mature and ripen, and the winter colors again shine forth.

These observations may be made anywhere in America, practically, for the willow is almost indifferent to locality, growing everywhere that its far-reaching roots can find the moisture which it loves, and which it rapidly transpires to the thirsty air. As Miss Keeler well remarks, "The genus Salix is admirably fitted to go forth and inhabit the earth, for it is tolerant of all soils and asks only water. It creeps nearer to the North Pole than any other woody plant except its companion the birch. It trails upon the ground or rises one hundred feet in the air. In North America it follows the water-courses to the limit of the temperate zone, enters the tropics, crosses the equator, and appears in the mountains of Peru and Chili.... The books record one hundred and sixty species in the world, and these sport and hybridize to their own content and to the despair of botanists. Then, too, it comes of an ancient line; for impressions of leaves in the cretaceous rocks show that it is one of the oldest of plants."

Common it is, and therefore overlooked; but the reader may well resolve to watch the willow in spring and summer, with its bloom and fruit; to follow its refreshing color through winter's chill; to observe its cheer and dignity; and to see the wind toss its slender wands and turn its graceful leaves.

The poplars and the willows are properly considered together, for together they form the botanical world family of the _Salicaceæ_. Many characteristics of bloom and growth, of sap and bark, unite the two, and surely both, though alike common to the world, are common and familiar trees to the dwellers in North America.

One of my earliest tree remembrances has to do with a spreading light-leaved growth passed under every day on the way to school--and, like most school-boys, I was not unwilling to stop for anything of interest that might put off arrival at the seat of learning. This great tree had large and peculiar winter buds, that always seemed to have advance information as to the coming of spring, for they would swell out and become exceedingly shiny at the first touch of warm sun. Soon the sun-caressing would be responded to by the bursting of the buds, or the falling away of their ingenious outer protecting scales, which dropped to the ground, where, sticky and shining, and extraordinarily aromatic in odor, they were just what a curious school-boy enjoyed investigating. "Balm of Gilead" was the name that inquiry brought for this tree, and the resinous and sweet-smelling buds which preceded the rather inconspicuous catkins or aments of bloom seemed to justify the Biblical designation.

Nearly a world tree is this poplar, which in some one of its variable forms is called also tacamahac, and balsam poplar as well. Its cheerful upright habit, really fine leaves and generally pleasing air commend it, but there is one trouble--it is almost too vigorous and anxious to spread, which it does by means of shoots or "suckers," upspringing from its wide area of root-growth, thus starting a little forest of its own that gives other trees but small chance. But on a street, where the repression of pavements and sidewalks interferes with this exuberance, the balsam poplar is well worth planting.

The poplars as a family are pushing and energetic growers, and serve a great purpose in the reforestation of American acres that have been carelessly denuded of their tree cover. Here the trembling aspen particularly, as the commonest form of all is named, comes in to quickly cover and shade the ground, and give aid to the hard woods and the conifers that form the value of the forest growth.

This same American aspen, a consideration of the lightly hung leaves of which has been useful to many poets, is a well-known tree of graceful habit, particularly abundant in the forests north of Pennsylvania and New Jersey, and occupying clearings plentifully and quickly. Its flowers are in catkins, as with the rest of the family, and, like other poplars, they are in two kinds, male and female, or staminate and pistillate, which accounts for some troubles the inexperienced investigator has in locating them.

There is another aspen, the large-toothed form, that is a distinct botanical species; but I have never been able to separate it, wherefore I do not try to tell of it here, lest I fall under condemnation as a blind leader, not of the blind, but of those who would see!

In many cities, especially in cities that have experienced real-estate booms, and have had "extensions" laid out "complete with all improvements," there is to be seen a poplar that has the merit of quick and pleasing growth and considerable elegance as well. Alas, it is like the children of the tropics in quick beauty and quick decadence! The Carolina poplar, it is called, being a variety of the wide-spread cottonwood. Grow? All that is needed is to cut a lusty branch of it, point it, and drive it into the earth--it will do the rest!

This means cheap trees and quick growth, and that is why whole new streets in West Philadelphia, for instance, are given up to the Carolina poplar. Its clear, green, shining leaves, of good size, coming early in spring; its easily guided habit, either upright or spreading; its very rapid growth, all commend it. But its coarseness and lack of real strength, and its continual invitation to the tree-butcher and the electric lineman, indicate the undesirability of giving it more than a temporary position, to shade while better trees are growing.

But I must not get into the economics of street-tree planting. I started to tell of the blossoms of this same Carolina poplar, which are decidedly interesting. Just when the sun has thoroughly warmed up the air of spring there is a sudden, rapid thickening of buds over one's head on this poplar. One year the tree under my observation swelled and swelled its buds, which were shining more and more in the sun, until I was sure the next day would bring a burst of leaves. But the weather was dry, and it was not until that wonderful solvent and accelerator of growing things, a warm spring rain, fell softly upon the tree, that the pent-up life force was given vent. Then came, not leaves, but these long catkins, springing out with great rapidity, until in a few hours the tree glowed with their redness. A second edition of the shower, falling sharply, brought many of the catkins to the ground, where they lay about like large caterpillars.

The whole process of this blooming was interesting, curious, but hardly beautiful, and it seemed to fit in with the restless character of the poplar family--a family of trees with more vigor than dignity, more sprightliness than grace. As Professor Bailey says of the cottonwood, "It is cheerful and restive. One is not moved to lie under it as he is under a maple or an oak." Yet there are not wanting some poplars of impressive character.

One occurs to me, growing on a wide street of my home town, opposite a church with a graceful spire. This white or silver-leaved poplar has for many years been a regular prey of the gang of tree-trimmers, utterly without knowledge of or regard for trees, that infests this town. They hack it shamefully, and I look at it and say, "Well, the old poplar is ruined now, surely!" But a season passes, and I look again, to see that the tremendous vigor of the tree has triumphed over the butchers; its sores have been concealed, new limbs have pushed out, and it has again, in its unusual height, assumed a dignity not a whit inferior to that of the church spire opposite.

This white poplar is at its best on the bank of a stream, where its small forest of "suckers" most efficiently protects the slope against the destructive action of floods. One such tree with its family and friends I saw in full bloom along the Susquehanna, and it gave an impression of solidity and size, as well as of lusty vigor, and I have always liked it since. The cheerful bark is not the least of its attractions--but it is a tree for its own place, and not for every place, by reason of the tremendous colonizing power of its root-sprouts.

I wonder, by the way, if many realize the persistence and vigor of the roots of a tree of the "suckering" habit? Some years ago an ailanthus, a tree of vigor and beauty of foliage but nastiness of flower odor, was cut away from its home when excavation was being made for a building, which gave me opportunity to follow a few of its roots. One of them traveled in search of food, and toward the opportunity of sending up a shoot, over a hundred feet!

The impending scarcity of spruce logs to feed the hungry maws of the machines that make paper for our daily journals has turned attention to several forms of the rapid-growing poplar for this use. The aspen is acceptable, and also the Carolina poplar, and these trees are being planted in large quantities for the eventual making of wood-pulp. Even today, many newspapers are printed on poplar, and exposure to the rays of the truth-searching sun for a few hours will disclose the yellowness of the paper, if not of the tree from which it has been ground.

Few whose eyes are turned upward toward the trees have failed to note that exclamation-point of growth, the Lombardy poplar. Originating in that portion of Europe indicated by its common name, and, indeed, a botanical form of the European black poplar, it is nevertheless widely distributed in America. When it has been properly placed, it introduces truly a note of distinction into the landscape. Towering high in the air, and carrying the eye along its narrowly oval contour to a skyward point, it is lofty and pleasing in a park. It agreeably breaks the sky-line in many places, and is emphatic in dignified groups. To plant it in rows is wrong; and I say this as an innocent offender myself. In boyhood I lived along the banks of the broad but shallow Susquehanna, and enjoyed the boating possible upon that stream when it was not reduced, as graphically described by a disgusted riverman, to merely a heavy dew. Many times I lost my way returning to the steep bluff near my home after the sun had gone to rest, and a hard pull against the swift current would ensue as I skirted the bank, straining eyes for landmarks in the dusk. It occurred to me to plant six Lombardy poplars on the top of the bluff, which might serve as easily recognized landmarks. Four of them grew, and are now large trees, somewhat offensive to a quickened sense of appropriateness. Long since the old home has been swallowed up by the city's advance, and I suppose none who now see those four spires of green on the river-bank even guess at the reason for their existence.

The poplar family, as a whole, is exuberant with vigor, and interesting more on that account than by reason of its general dignity or strength or elegance. It is well worth a little attention and study, and the consideration particularly of its bloom periods, to which I commend the tree-sense of my readers as they take the tree walks that ought to punctuate these chapters.

The Elm and the Tulip

America has much that is unique in plant and tree growth, as one learns who sees first the collections of American plants shown with pride by acute gardeners and estate owners in England and on the European Continent. Many a citizen of our country must needs confess with some shame that his first estimation of the singular beauty of the American laurel has been born in England, where the imported plants are carefully nurtured; and the European to whom the rhododendrons of his own country and of the Himalayas are familiar is ready to exclaim in rapture at the superb effect and tropical richness of our American species, far more lusty and more truly beautiful here than the introductions which must be heavily paid for and constantly coddled.

For no trees, however, may Americans feel more pride than for our American elms and our no less American tulip, the latter miscalled tulip "poplar." Both are trees practically unique to the country, both are widespread over Eastern North America, both are thoroughly trees of the people, both attain majestic proportions, both are long-lived and able to endure much hardship without a full giving up of either beauty or dignity.
