FERNS, FENCES, AND WHITE BIRCHES

(Barbara Campbell to Mary Penrose)

_Hemlock Hills, July 3._ For nearly a week we have been sauntering through this most entrancing hill country, practically a pedestrian trip, except that the feet that have taken the steps have been shod with steel instead of leather. Your last chronicle has followed me, and was read in a region so pervaded by ferns that your questions concerning their transplanting would have answered themselves if you could have only perched on the rock beside me. There is a fern-lined ravine below, a fern-bordered road in front; and above a log cottage, set in a clearing in the hemlocks which has for its boundaries the tumble-down fence piled by the settlers a century or two ago, its crevices now filled by leaf-mould, has become at once a natural fernery and a barrier. Why do you not use your old wall in a like manner? Of course your stones may be too closely piled and lack the time-gathered leaf-mould, but a little discretion in removing or tipping a stone here and there, and a crowbar for making pockets, would work wonders. You might even exchange the surplus rocks for leaf-mould, load by load; at any rate large quant.i.ties of fern soil must be obtainable for the carting at the reservoir woods.

Imagine the effect, if you please, of that irregular line of rocks swathed in vines and sheltering great clumps of ferns, while it will afford an endless shelter for every sort of wild thing that you may pick up in your rambles. Of course you need not plant it all at once, but having made the plan, develop it at leisure.

You should never quite finish a country place unless you expect to leave it. The something more in garden life is the bale of hay before the horse's nose on the uphill road. Last year, for almost a week, we thought our garden quite as finished as the material and surroundings would allow,--it was a strange, dismal, hollow sort of feeling. However, it was soon displaced by the desire that I have to collect my best roses in one spot, add to them, and gradually form a rosary where the Garden Queen and all her family may have the best of air, food, and lodgings.

You see I feared that the knoll, hardy beds, and rose garden were not sufficient food for your mind to ruminate, so I add the fern fence as a sort of dessert!

[Ill.u.s.tration: AN ENDLESS SHELTER FOR EVERY SORT OF WILD THING.]

"Where is the shade that ferns need?" I hear you ask, "for except under some old apple trees and where the bird cherries grow (and they, though beautiful at blooming time and leaf fall, attract tent caterpillars), the stone wall lies in the sun!"

Yes, but in one of the woodland homes of this region I have seen a screen placed by such a rustic stone fence that it not only served the purpose of giving light shade, but was a thing of beauty in itself, dividing the vista into many landscapes, the frame being long or upright according to the planter's fancy.

Do you remember the old saying "When away keep open thine eyes, and so pack thy trunk for the home-going?"

On this drive of ours I've been cramming my trunk to overflowing, and yet the ideas are often the simplest possible, for the people of this region, with more inventive art than money, have the perfect gift of adapting that which lies nearest to hand.

You spoke in your last chronicle of the screen of white birches through which you saw the sun rise over the meadows of Opal Farm. This birch springs up in waste lands almost everywhere. We have it in abundance in the wood lot on the side of our hill, and it is scattered through the wet woods below our wild walk, showing that all it needs is a foothold.

Because it is common and the wood rather weak and soft, landscape gardening has rather pa.s.sed it by, turning a cold shoulder, yet the slender tree is very beautiful. True, it has not the length of life, the girth and strength of limb, of the silver-barked canoe birch, but the white birch will grow in a climate that fevers its northern cousin. In spite of its delicate qualities, it is not a trivial tree, for I have seen it with a bole of more than forty feet in length, measuring eighteen inches through at the ground. When you set it, you are not planting for posterity, perhaps, but will gain a speedy result; and the fertility of the tree, when once established, will take care of the future.

What is more charming after a summer shower than a natural cl.u.s.ter of these picturesque birches, as they often chance to group themselves in threes, like the Graces--the soft white of the trunks, with dark hieroglyphic shadows here and there disappearing in a drapery of glossy leaves, green above and reflecting the bark colour underneath, all a-quiver and more like live things poised upon the russet twigs than delicate pointed leaves! Then, when the autumn comes, how they stand out in company with cedar bushes and sheep laurel on the hillsides to make beautiful the winter garden, and we stand in mute admiration when these white birches reach from a s...o...b..nk and pencil their frosty tracery against a wall of hemlocks.

This is the simple material that has been used with such wonderful effect. In the gardens hereabout they have flanked their alleys with the birches, for even when fully grown their habit is more poplar-like than spreading, and many plants, like lilies, requiring partial shade flourish under them; while for fences and screens the trees are planted in small groups, with either stones and ferns, or shrubs set thick between, and the most beautiful winter fence that Evan says he has ever seen in all his wanderings amid costly beauty was when, last winter, in being here to measure for some plans, he came suddenly upon an informal boundary and screen combined, over fifty feet in length, made of white birches,--the groups of twos and threes set eight or ten feet apart, the gaps being filled by j.a.panese barberries laden with their scarlet fruit.

Even now this same screen is beautiful enough with its shaded greens, while the barberries in their blooming time, and the crimson leaf glow of autumn, give it four distinct seasons.

The branches of the white birch being small and thickly set, they may be trimmed at will, and windows thus opened here and there without the look of artifice or stiffness.

Fences are always a moot question to the gardener, for if she has a pleasant neighbour, she does not like to raise an aggressive barrier or perhaps cut off the view, yet to a certain extent I like being walled in at least on two sides. A total lack of boundaries is too impersonal,--the eye travels on and on: there is nothing to rest it by comparison. Also, where there are no fences or hedges,--and what are hedges but living fences,--there is nothing to break the ground draught in winter and early springtime. The ocean is much more beautiful and full of meaning when brought in contact with a slender bit of coast. The moon has far more majesty when but distancing the tree-tops than when rolling apparently at random through an empty sky. A vast estate may well boast of wide sweeps and open places, but the same effect is not gained, present fas.h.i.+on to the contrary, by throwing down the barriers between a dozen homes occupying only half as many acres. Preferable is the cosey English walled villa of the middle cla.s.s, even though it be a bit stuffy and suggestive of earwigs. The question should not be to fence or not to fence, but rather _how_ to fence usefully and artistically, and any one who has an old stone wall, such as you have, moss grown and tumble-down, with the beginnings of wildness already achieved, has no excuse for failure. We have seen other fences here where bushes, wire, and vines all take part, but they cannot compete with an old wall.

With ferns, a topic opens as long and broad and deep as the glen below us, and of almost as uncertain climbing, for it is not so much what ferns may be dug up and, as individual plants, continue to grow in new surroundings, but how much of their haunt may be transplanted with them, that the fern may keep its characteristics. Many people do not think of this, nor would they care if reminded. Water lilies, floating among their pads in the still margin of a stream, with jewelled dragon-flies darting over, soft clouds above and the odour of wild grapes or swamp azalea wafting from the banks, are no more to them than half a dozen such lilies grown in a sunken tub or whitewashed basin in a backyard; rather are they less desirable because less easily controlled and encompa.s.sed. Such people, and they are not a few, belong to the tribe of Peter Bell, who saw nothing more in the primrose by the river's brim than that it was a primrose, and consequently yellow. Doubtless it would have looked precisely the same to him, or even more yellow, if it had bloomed in a tin can!

We do not treat our native ferns with sufficient respect. Homage is paid in literature to the palm, and it is an emblem of honour, but our New England ferns, many of them equally majestic, are tossed into heaps for hay and mown down by the ruthless scythe of the farmer every autumn when he shows his greatest agricultural energy by stripping the waysides of their beauty prior to the coming of the roadmender with his awful "turn-piking" process. If, by the way, the automobilists succeed in stopping this piking practice, we will print a nice little prayer for them and send it to Saint Peter, so that, though it won't help them in this world,--that would be dangerous,--it will by and by!

In the woods the farmer allows the ferns to stand, for are they not one of the usual attributes of a picnic? Stuck in the horses' bridle, they keep off flies; they serve to deck the tablecloth upon which the food is spread; gathered in armfuls, they somewhat ease the contact of the rheumatic with the rocks, upon which they must often sit on such occasions. They provide the young folks with a motive to seek something further in the woods, and give the acquisitive ladies who "press things"

much loot to take home, and all without cost.

This may not be respectful treatment, but it is not martyrdom; the fern is a generous plant, a thing of wiry root-stock and prehistoric tenacity; it has not forgotten that tree ferns are among its ancestors; when it is discouraged, it rests and grows again. But imagine the feelings of a mat of exquisite maidenhair rent from a shady slope with moss and partridge vine at its feet, and quivering elusive woodland shade above, on finding itself unceremoniously crowded into a bed, between cannas or red geraniums! Or fancy the despair of either of the wide-spreading Osmundas, lovers of stream borders opulent with leaf-mould, or wood hollows deep with moist richness, on finding themselves ranged in a row about the porch of a summer cottage, each one tied firmly to a stake like so many green parasols stuck in the dry loam point downward!

It is not so much a question of how many species of native ferns can be domesticated, for given sufficient time and patience all things are possible, but how many varieties are either decorative, interesting, or useful away from their native haunts. For any one taking what may be called a botanical interest in ferns, a semi-artificial rockery, with one end in wet ground and the other reaching dry-wood conditions, is extremely interesting. In such a place, by obtaining some of the earth with each specimen and tagging it carefully, an out-of-door herbarium may be formed and something added to it every time an excursion is made into a new region. Otherwise the ferns that are worth the trouble of transplanting and supplying with soil akin to that from which they came, are comparatively few. Of decorative species the Osmundas easily lead; being natives of swampy or at least moist ground, they should have a like situation, and yet so strong are their roots and crown of leaves that they will flourish for years after the moisture that has fed them has been drained and the shading overgrowth cut away, even though dwarfed in growth and coa.r.s.ened in texture. Thus people seeing them growing under these conditions in open fields and roadside banks mistake their necessities.

The Royal fern (_Osmunda regalis_) positively demands moisture; it will waive the matter of shade in a great degree, but water it must have.

The Cinnamon fern, that encloses the spongelike, brown, fertile fronds in the circle of green ones, gains its greatest size of five feet in roadside runnels or in springy places between boulders in the river woods; yet so accommodating is it that you can use it at the base of your knoll if a convenient rock promises both reasonable dampness and shelter.

The third of the family (_Osmunda Claytonia_) is known as the Interrupted fern, because in May the fertile black leaflets appear in the middle of the fronds and interrupt the even greenness. This fern will thrive in merely moist soil and is very charming early in the season, but like the other two, out of its haunts, cannot be relied upon after August.

As a fern for deep soil, where walking room can be allowed it, the common brake, or bracken (_Pteris aquilina_) is unsurpa.s.sed. It will grow either in sandy woods or moist, and should have a certain amount of high shade, else its broad fronds, held high above the ground umbrella-wise, will curl, grow coa.r.s.e, and lose the fernlike quality altogether. You can plant this safely in the bit of old orchard that you are giving over to wild asters, black-eyed Susan, and sundrops, but mind you, be sure to take both Larry and Barney, together with a long post-hole spade, when you go out to dig brakes,--they are not things of shallow superficial roots, I can a.s.sure you.

A few years ago Evan, Timothy Saunders, and I went brake-hunting, I selecting the groups and the menkind digging great solid turfs a foot or more in depth, in order to be sure the things had native earth enough along to mother them into comfortable growth. Proudly we loaded the big box wagon, for we had taken so much black peat (as the soil happened to be) that not a root hung below and success was certain.

When, on reaching home, in unloading, one turf fell from the cart and crumbled into fragments, to my dismay I found that the long, tough stalk ran quite through the clod and we had no roots at all, but that (if inanimate things can laugh) they were all laughing at us back in the meadow and probably another foot underground. Yet brakes are well worth the trouble of deep digging, for if once established, a waste bit, where little else will flourish, is given a graceful undergrowth that is able to stand erect even though the breeze plays with the little forest as it does with a field of grain. Then, too, the brake patch is a treasury to be drawn from when arranging tall flowers like foxgloves, larkspurs, hollyhocks, and others that have little foliage of their own.

The fact that the brake does not mature its seeds that lie under the leaf margin until late summer also insures it a long season of sightliness, and when ripeness finally draws nigh, it comes in a series of beautiful mellow shades, varying from straw through deep gold to russet, such as the beech tree chooses for its autumn cloak.

Another plant there is, a low-growing shrub, having long leaves with scalloped edges, giving a spicy odour when crushed or after rain, that I must beg you to plant with these brakes. It is called Sweet-fern, merely by courtesy, from its fernlike appearance, for it is of the bayberry family and first cousin to sweet gale and waxberry.

The digging of this also is a process quite as elusive as mining for brakes; but when once it sets foot in your orchard, and it will enjoy the drier places, you will have a liberal annex to your bed of sweet odours, and it may worthily join lemon balm, mignonette, southernwood, and lavender in the house, though in the garden it would be rather too pus.h.i.+ng a companion.

Next, both decorative and useful, comes the Silvery Spleenwort, that is content with shade and good soil of any sort, so long as it is not rank with manure. It has a slender creeping root, but when it once takes hold, it flourishes mightily and after a year or so will wave silver-lined fronds three feet long proudly before you, a rival of Osmunda!

A sister spleenwort is the beautiful Lady fern, whose lacelike fronds have party-coloured stems, varying from straw through pink and reddish to brown, giving an unusual touch of life and warmth to one of the cool green fern tribe. In autumn the entire leaf of this fern, in dying, oftentimes takes these same hues; it is decorative when growing and useful to blend with cut flowers. It naturally prefers woods, but will settle down comfortably in the angle of a house or under a fence, and will be a standby in your wall rockery.

The ferns that seem really to prefer the open, one taking to dry and two to moist ground, are the hay-scented fern (_d.i.c.ksonia punctilobula_), the New York fern (_Dryopteris Noveboracencis_), and the Marsh s.h.i.+eld-fern. d.i.c.ksonia has a pretty leaf of fretwork, and will grow three feet in length, though it is usually much shorter. It is the fern universal here with us, it makes great swales running out from wood edges to pastures, and it rivals the bayberry in covering hillsides; it will grow in dense beds under tall laurels or rhododendrons, border your wild walk, or make a setting of cheerful light green to the stone wall; while if cut for house decoration, it keeps in condition for several days and almost rivals the Maidenhair as a combination with sweet peas or roses.

The New York fern, when of low stature, is one of the many bits of growing carpet of rich cool woods. If it is grown in deep shade, the leaves become too long and spindling for beauty. When in moist ground, quite in the open, or in reflected shade, the fresh young leaves of a foot and under add great variety to the gra.s.s and are a perfect setting for table decorations of small flowers. We have these ferns all through the dell. If they are mown down in June, July sees a fresh crop, and their spring green is held perpetual until frost.

The Marsh s.h.i.+eld-fern of gentian meadows is the perfect small fern for a bit of wet ground, and is the green to be used with all wild flowers of like places. One day last autumn I had a bouquet of gra.s.s-of-Parna.s.sus, ladies' tresses, and gentian ma.s.sed thickly with these ferns, and the posey lived for days on the sunny window shelf of the den (for gentians close their eyes in shade),--a bit of the September marshland brought indoors.

The two Beech-ferns, the long and the broad, you may grow on the knoll; give the long the dampest spots, and place the broad where it is quite dry. As the rootstocks of both these are somewhat frail, I would advise you to peg them down with hairpins and cover well with earth. By the way, I always use wire hairpins to hold down creeping rootstocks of every kind; it keeps them from springing up and drying before the rootlets have a chance to grasp the soil.

The roots of Maidenhair should always be treated in this way, as they dry out very quickly. This most distinctive of our New England ferns will grow between the rocks of your knoll, as well as in deep nooks in the fence. It seems to love rich side-hill woods and craves a rock behind its back, and if you are only careful about the soil, you can have miniature forests of it with little trouble. As for maidenhair, all its uses are beauty!

Give me a bouquet of perfect wild rosebuds within a deep fringe of maidenhair to set in a crystal jar where I may watch the deep pink petals unfold and show the golden stars within; let me breathe their first breath of perfume, and you may keep all the greenhouse orchids that are grown.

Though you can have a variety of ferns in other locations, those that will thrive best on the knoll and keep it ever green and in touch with laurel and hemlock, are but five,--the Christmas fern, the Marginal s.h.i.+eld-fern, the common Rock Polypody, the Ebony Spleenwort, and the Spinulose Wood-fern. Of the first pair it is impossible to have too many. The Christmas fern, with its glistening leaves of holly green, has a stout, creeping rootstock, which must be firmly secured, a few stones being added temporarily to the hairpins to give weight. The Evergreen Wood-fern and Ebony Spleenwort, having short rootstocks, can be tucked into sufficiently deep holes between rocks or in the hollows left by small decayed stumps, while the transplanting of the Rock Polypody is an act where luck, recklessness, and a pinch of magic must all be combined.

You will find vast mats of these leathery little Polypodys growing with rock-selaginella on the great boulders of the river woods. As these are to be split up for masonry, the experiment of transferring the polypody is no sin, though it savours somewhat of the process of skin-grafting.

Evan and I have tried the experiment successfully, so that it is no fable. We had a bit of shady bank at home that proved by the mosses that grew on it that it was moistened from beneath the year through. The protecting shade was of tall hickories, and a rock ledge some twenty feet high s.h.i.+elded it from the south and east. We sc.r.a.ped the moss from a circle of about six feet and loosened the surface of the earth only, and very carefully. Then we spread some moist leaf-mould on the rough but flat surface of a partly exposed rock. Going to a near-by bit of woods that was being despoiled, as in your valley, we chose two great mats of polypody and moss that had no piercing twigs to break the fabric, and carefully peeled them from the rocks, as you would bark from a tree, the matted rootstocks weaving all together. Moistening these thoroughly, we wrapped them in a horse blanket and hurried home. The earth and rock already prepared were sprinkled with water and the fern fabric applied and gently but firmly pressed down, that resting on the earth being held by the ever useful hairpin!

The rock graft was more difficult, but after many failures by way of stones that rolled off, a coa.r.s.e network of cords was put across and fastened to whatever twigs or roots came in the way. Naturally a period of constant sprinkling followed, and for that season the rock graft seemed decidedly homesick, but the next spring resignation had set in, and two years later the polypodys had completely adopted the new location and were prepared to appropriate the whole of it.

So you see that there are comparatively only a few ferns, after all, that are of great value to The Garden, You, and I, and likewise there are but a few rules for their transplanting, viz.:--

Don't bother about the tops, for new ones will grow, but look to the roots, and do not let them be exposed to the air or become dry in travel. Examine the quality of soil from which you have taken the ferns, and if you have none like it nearer home, take some with you for a starter! Never dig up more on one day than you can plant during the next, and above all remember that if a fern is worth tramping the countryside for, it is worth careful planting, and that the moral remarks made about the care in setting out of roses apply with double force to the handling of delicate wild flowers and ferns.

Good luck to your knoll, Mary Penrose, and to your fern fence, if that fancy pleases you. May the magic of fern seed fill your eyes and let you see visions, the goodly things of heart's desire, when, all being accomplished, you pause and look at the work of your hands.

"And nimble fay and pranksome elf Flash vaguely past at every turn, Or, weird and wee, sits Puck himself, With legs akimbo, on a fern!"
