That almond culture in California is rapidly becoming an important and successful industry, we have an ocular demonstration in the tons of these valuable nuts received from there in the past few years, and placed on sale in Eastern markets. If one man, by his individual efforts, can revolutionize or establish a great industry in a region as large as the State of California, it is not too much to expect that something of the kind could be done elsewhere, with the combined efforts of several men. If the varieties heretofore tried in the East are unsuited to the climate, it is certainly within the range of probabilities that others better adapted to surrounding conditions can be produced. The native grape, raspberry and strawberry have had a history similar to the almond, but now all are extensively and successfully cultivated.
Propagation of the Almond.—The propagation of the almond is identical with that of the peach: that is, from seed to procure new varieties, or by budding the more desirable ones, when obtained, upon seedling almond, peach or plum stocks. The half-wild hard-shelled almond is probably the most congenial and best stock for this purpose, but seedlings of the peach are most generally employed because the most abundant and cheapest. Under certain conditions, such as cold, heavy, moist soils, and where rather dwarfish trees are desired, the plum may be employed with advantage as a stock, but it is not to be recommended for general orchard culture. In mild climates seedlings of the best of the soft-shelled varieties may be raised and planted in orchards without budding, but the nuts from such trees are likely to be somewhat variable in size and quality, although the trees will usually prove to be as healthy and productive as those subjected to artificial modes of propagation. If, however, the grower desires a uniform product, he must resort to the usual means of obtaining it; that is, multiplying superior or distinct varieties by budding, either upon peach, almond or other stocks. It is advisable, as well as exceedingly important, for all who intend or feel inclined to cultivate almonds in regions where the adaptation of this nut has not been fully established by years of practical experience, that seedlings should be raised in large numbers, and from these a selection be made to meet the requirements of the climate and other conditions under which they are to be propagated and grown. If spring frosts have been heretofore inimical to the cultivation of the almond, then the production of late-blooming varieties would be a remedy. There will also be variations in the season of ripening; some may come on too early, others far too late for special localities, but all these faults or variations may be readily overcome by raising seedlings, and then selecting for propagation those coming nearest fulfilling the requirements of local conditions or circumstances. It is by such experiments and means that fruit culture has reached its present position in this and all other countries, where it is practiced as an art or industrial pursuit. Varieties that have become exceedingly popular and profitable in one locality or country, may not have succeeded elsewhere, and this holds good with all cultivated plants.
In making experiments with the almond in regions where it has not been cultivated, but under conditions which appear to be favorable, I would certainly advise testing the well-known varieties first, and if these fail, then see what can be done in the way of producing new ones adapted to the locality and climate.
Raising Seedlings for Stocks.—In warm or moderately mild climates the nuts, whether peach or almond, may be planted soon after they are gathered in the fall, but should the weather continue warm and moist the nuts will sometimes sprout prematurely and the young sprouts get frosted later in the season, and for this reason it is better to store them in a cool room, packed in dry sand or soil, until the approach of steady cold weather, and then plant. Having lost choice kinds of nuts from being in too great haste in getting them into the ground in the fall, I am prompted to give this warning to those who have had no experience in raising nut trees. If not convenient to plant in the fall, nuts of all kinds may be packed in barrels, boxes, or similar vessels, mixed with or stratified with sharp sand or light soil, then stored in a dry, cool place,—a very cool cellar will answer, but in my experience, out of doors is preferable,—and in the shade of some evergreen tree or on the north side of a building, and there banked over with earth just sufficient to keep the nuts at an equably low temperature. It is advisable to have a few small holes in the bottom of the barrels or boxes, to insure proper drainage, should any considerable amount of water get in at the top; but this will not occur if the vessels are properly covered with boards when placed in position for winter.
It must also be kept in mind that mice, squirrels and chipmunks are fond of almonds and other kinds of edible nuts, and if placed where these little rodents can find them, they are sure to take a share, or perhaps the entire store, before their visits are discovered. I have known field mice to dig down under boxes of nuts, enlarge the holes left for drainage, and spend the winter among the chestnuts which I had put away for planting in spring. The safest way is to place fine wire netting on the bottom of the box, and then cover it with the same. Owing to the abundance of mice and other little nut-eating animals, I have never dared to plant out nuts in the fall, and so have always stored them in sand, but out of doors during the winter, and well covered with earth. In other localities it may be safe to sow in autumn, and if protection from vermin is required, coat the nuts with gas tar, the same as practiced by farmers in protecting seed corn against the attacks of crows and other corn-pulling birds. One pint of warm tar will be sufficient for a bushel of nuts, and the application is readily made by placing the nuts in a barrel, pouring the tar on them, and stirring with a stick until every nut is coated. To prevent the tar sticking to the hands in planting, dust the nuts with dry wood ashes, land plaster, or fine dry sand.
If peach stones are to be planted for stocks they may be put into the ground as soon as ready in autumn, because they are rarely disturbed by vermin; or if more convenient, mix with common soil, and in heaps, in the open ground, and leave in this position until spring, then pick out as they begin to sprout, and plant. The hard-shelled almond may be treated in the same way, only they are not to be handled quite as roughly as peach stones, and for protection it is best to put them in barrels or boxes, as described above.
When ready for planting take out the nuts and drop them in shallow drills, one every ten or twelve inches, then cover with about two inches of soil. It is to be supposed, of course, that a seed bed has been prepared, by thorough working over and enriching, if necessary, in advance of planting. The distance between the drills or rows should be sufficient to admit of cultivating the plants with a horse or mule, and cultivator, during the summer, and if this is done and the soil stirred often enough to keep down all weeds, the stocks should become large enough to admit of budding the first season; if not, then this operation must be deferred until the following year. But in case the seedlings are raised from choice varieties and to be left in their natural condition for fruiting, they may be lifted when one or two seasons old and set where they are to remain permanently.
The Season for Budding.—So much depends upon climate, location, and variation of seasons, that no special date or time can be given for budding trees of any kind, but it is always to be done while the stocks are in active growth, because the bark must part freely from the wood underneath, in order to admit of inserting the bud under it. If the buds are set too early in the season there is danger of a premature growth; that is, of pushing out a shoot in the fall instead of remaining dormant until the following spring. Under certain conditions, however, and for special purposes, it may be advisable to force the buds as soon as they have formed a union with the stock, but as a rule, in the propagation of hardy and half-hardy trees, it is better to keep the buds dormant during the cool or cold winter months.
Here in the Northern States we usually begin to look over our stocks during the latter part of July or first week in August, and note their progress and condition. Should they show the least signs of cessation of growth, we begin budding them, and push the work as rapidly as possible. If the season is a wet one the stocks may continue to grow and remain in good condition for budding until the middle of September; but in a dry season they may cease to grow in August, and it is these variable conditions which gives to the close observer and man of experience such an advantage over the novice in the propagation of plants. It is better to begin budding too early than to be a few days too late.
The operation called budding consists in taking a bud, with a small portion of the bark adjoining, from one plant, and inserting it in another, or in some other part of the same plant from which it was taken. The physiological principles which govern the operation are, that there must exist an affinity between the plant from which the bud is taken and the one upon which it is to be placed, and the nearer the relationship the more readily will it unite and the more perfect the union. For instance, the cultivated peach and almond are supposed to be of the same origin, and descendants of one original species; consequently there is a close relationship between the varieties of both sections, and their seedlings may be employed indiscriminately for stocks. The next nearest relatives in the family line are the plums (Prunus), some of which answer very well as stocks for the almond, although very rarely used for this purpose. The next group in the line of botanical relationship are the cherries (Prunus cerasus), but these are too far removed to be employed as stocks for either the peach or almond.
For budding are necessary a small knife for preparing the buds for insertion and making an incision in the bark of the stock to admit them; and a quantity of some material to tie around the stock, so as to hold the bud in place. Budding knives are made after various patterns; one that is commonly used has an ivory or bone handle, made very thin at the end, that is used to peel the bark from the stock where the bud is to be inserted (Fig. 2). Another form of budding knife is made with a horn handle, and a small tapering piece of ivory fastened in the end. These knives, of various shapes and sizes, can be had at the seed stores; but another and quite a different form of budding knife is shown in Fig. 3, and is known as the "Yankee budding knife." It is merely a small one-bladed pocket knife with a thin blade, round at the end. The cutting portion extends about one-third around the end of the blade and two-thirds of its length, leaving the lower part dull. Although this form of budding knife has been in constant use in some of the older nurseries in this country for nearly a century, it does not appear to have been manufactured for the general trade, but only on special orders for nurserymen. It is so simple a knife, however, that with a little grinding almost any small one-bladed pocket knife can be transformed into one of these handy budding knives. The rounded end of the blade is used for lifting the bark, and for rapid work it is far more convenient than any form of knife that must be reversed in the hand every time a bud is inserted. In addition, a polished bit of steel is smoother and far less likely to lacerate the alburnous matter between the bark and wood than the best piece of bone or ivory. It may be said, however, that it is immaterial what form of knife is employed, provided it has a keen edge and is dexterously used.
The material most commonly used in times past for tying in the bud is the inner bark of the linden or basswood tree, usually called bass, and always to be procured in the form of mats, or as prepared from our indigenous basswoods and kept on sale at the seed stores. Recently, however, another excellent tying material has come into use, known in the trade as raffia or roffia. It is the cuticle of the Jupati palms. One species (Raphia tædigera) is a native of the lower valley of the Amazon and Orinoco, and another (R. Ruffia) of Madagascar and adjacent islands. Raffia is somewhat softer and more pliable than the ordinary bass, although it does not hold its form quite as well; but it is so cheap, soft and strong, that it has become very popular, and is extensively used for budding and many other purposes. But if none of these tying materials are at hand, the inner bark of the persimmon, corn husks, cotton twine, woolen yarn, or even strips of old muslin and calico may be employed with equally as good results, although not as handy and convenient for such purposes. The amateur, with only a few stocks to bud, can readily improvise implements and materials for doing the work, even if they are not of the regulation type. In selecting buds, the young shoots of the present season's growth are preferred, and these should be taken from the most healthy and vigorous branches of bearing trees, if possible. The leaves should be immediately removed, not by breaking or pulling off with the hand, but by severing the leaf-stalks with a knife, as shown in Fig. 4. If the leaves have fallen from the twig, the buds may be too ripe, with some kinds of plants, but with the almond, and where only a few leaves near the base have dropped, all may be used with fair success. If there are any soft and immature buds on the upper part of the shoot, or any undeveloped ones at the base, they should be rejected. Success in budding depends very largely upon the condition of the stocks at the time the operation is performed. Unless the sap is flowing and in sufficient abundance to allow the bark to part or peel readily from the wood underneath, the bud is certain to fail. If the buds used should happen to be a little over-ripe or wholly dormant when placed in direct contact with the living tissues and the juices of the stock, they will absorb moisture and nutriment, and be as likely to unite and live as under opposite conditions.
In performing the operation of budding, the following rules may be observed: Take the twig from which the buds are to be removed, in the left hand, with the small end pointing under the left arm; insert the knife-blade half an inch, or a little more, below the bud, cutting through the bark and a little into the wood; pass the knife under the bud, and bring it out about the same distance above it, taking off the bud with the bark, and a thin slice of wood attached, as at c, Fig. 4. Then, if using the Yankee budding knife, or one of similar form, let the forefinger clasp the lower part of the blade, make the horizontal incision in the stock first, and from this an incision downward about an inch long,—or it may be twice this length without doing any harm,—being careful not to cut too deep. Lift up the edge of the bark by passing the back of the end of the blade (without removing it) up to the horizontal incision. Lift the bark on the other side in the same manner, the two incisions making a wound in the stock resembling the letter T, as shown in Fig. 5. If other forms of budding knives are used, the thin end of the ivory handle is thrust under the bark, raising it sufficiently to admit the bud. The budder holds the bud between the thumb and forefinger of his left hand while making the incision in the stock; and as the knife leaves it he places the lower point of the bark attached to the bud under the bark of the stock before this falls back into place, and thrusts it down into position. If the upper end of the bark attached to the bud does not pass completely under the bark of the stock, it must be cut across, so as to allow that which remains with the bud to fall into place and rest firmly on the wood of the stock, as shown in Fig. 6.
When the bud is in position and fitted to the stock, as shown, wind the raffia, or other material used, around the stock, both above and below, covering the entire incision, leaving only the bud and part of leafstalk uncovered. Of course experienced propagators have their own individual systems and modes of operation, but the above may be taken as a safe guide for the amateur budder. The ligatures should be loosened or removed as soon as the bud has become firmly united with the stock, which will usually be in ten or fifteen days, if at all. When the buds have failed, others may be inserted, provided, of course, the stocks are in condition to admit of the operation. Exceptions, however, may be made where the budding has been done so late in the season that the stock has ceased to grow by the time the buds have taken, and in such cases the ligatures may be left on later and removed any time before winter. In cold climates the snow, ice and water are likely to get in around the bud if the ligatures are not removed. But where the stocks are vigorous and the buds set early, there will be danger of the ligatures cutting into the bark as the stocks swell or increase in diameter, unless they are loosened or entirely removed.
Under ordinary circumstances budded stocks should not be headed back until the following spring, and then should be cut off two or three inches above the inserted bud; and when this pushes into growth, all suckers and sprouts below and above it should be rubbed off as they appear, for the object is to throw the entire strength of the stock into this one bud, and when this has made a growth of two or three feet the short stump of the stock above the base of the shoot may be carefully removed with a sharp knife. This is usually done the last of July or first of August, which gives time for the healing of the wound before the close of the growing season. Sometimes it may be necessary to place small stakes by the side of these shoots for their support and to prevent breaking at the point of union with the stock; but this will rarely be necessary, except in very exposed situations.
If the young trees make a fairly good growth they will be ready for planting out in the orchard the following spring, and one-year-old almond trees are usually preferable for transplanting than older. It is not advisable to prune these young trees during the growing season the first summer, but allow all the side shoots or branches to grow unchecked, for by so doing we secure a more stocky plant, if not as tall a one, than we would if trimming up was practiced. But when the trees are taken up for transplanting, in the late fall or early spring, then they may be pruned and the lateral branches cut off close to the main stem, leaving a naked rod, and if low-headed trees are desired (and they usually are), cut back the main stem to about three feet from the ground. If the young trees have made a growth of from four to six feet, then prune away the lateral branches to a hight of three feet or a little more, and cut in all branches above this point to within four to six inches of the main stem, leaving the buds on these stumps to form the head of the tree. Four or five branches at the top of the stem will be sufficient for the foundation for an open, round-headed tree, or in what may be termed a vase form, which is the best for almonds.
Soil and Exposure for Almonds.—The almond requires a warm, rather light and well-drained soil. Cold, heavy clays, and low, moist soils, whether light or heavy, are always to be avoided for the almond and closely allied trees. That the soil should be moderately rich is, of course, a condition required with all cultivated nut and fruit trees, but over-stimulation may result in excessive and immature growth late in the season, this leaving the twigs in such a state that they will be unable to resist even a few degrees of frost, to which they may be subjected the ensuing winter. In what are generally termed mild climates, or where the temperature seldom goes more than four to six degrees below the freezing point, hardy trees, if they have made a late growth, are often injured more than they would have been in a colder climate, with early matured wood. There are many kinds of what we consider very hardy trees and shrubs here in the North, that are very likely to be winterkilled or severely frosted when grown at the South, simply because the conditions are such that they do not ripen up in time to resist the cold.
In touching upon the subject of location for an almond orchard east of the Mississippi, I should be inclined to relegate this valuable nut to semi-tropical Florida, were it not for the fact that almost a score of ornamental species and varieties of the same genus,—to say nothing of the widely cultivated peach,—flourish over a very wide range of country and climate, and nowhere better than near the Atlantic ocean in the Middle and some of the Northern States. It is also generally conceded that several of what are called hard-shelled varieties thrive and bear fruit in nearly all of our best peach-growing regions. From all that I have been able to learn of almond culture, and with my own limited experience with this nut, experiments are wanting to prove that it cannot be successfully cultivated in the peach-growing region of the Eastern States. I will not say "profitably" cultivated, for this is a rather vague term when applied to horticultural operations of any kind. Success is not synonymous with profit; in fact, it is frequently quite the opposite, and an abundant crop may mean glutted markets and a corresponding loss to the producer. But, to return to location, the principal cause of failure in almond culture, where it has been tried in the older States, seems to be the early blooming of the trees and subsequent destruction of the embryo fruit by frosts. To avoid this, high, open, airy situations, and even the north side of hills, would certainly be preferable to southern slopes and protected locations, especially in the South or where the temperature in winter does not go low enough to kill the wood of the previous season's growth. Theoretically, we might suppose that there are many locations favorable to almond culture in the elevated regions of North Carolina and Tennessee, as well as in the northern tier of counties in Alabama and Georgia. But in the absence of carefully conducted experiments in these regions, we have only to wait for their consummation at some future time, to prove the truth or falsity of our theory.
In the rich, warm valleys of New Mexico, Arizona and California, congenial locations are plentiful, inasmuch as almost every variety of climate is at hand, with a temperature ranging from that of perpetual summer to the opposite extreme, and all to be found within a few miles, and frequently to be found in the same county. Under such conditions, it rests with the would-be cultivator to decide upon the kinds of fruits desired, then to seek a location best adapted to his purpose.
If, as claimed,—but not proven,—there are no limited or extended areas fitted for almond culture east of the Mississippi river, there are certainly plenty of such west of it, awaiting the industrious and intelligent nut culturist. Almond orchards have been planted in California and Arizona, and the quality of the nuts, as well as the quantity, is very satisfactory; but a greater number and more extensive orchards are needed to meet the home demand.
Planting and Pruning.—In planting and pruning the almond tree the same system should be adopted as with its near relative, the peach. One-year-old budded trees are preferred for planting in an orchard, to older, except in the case of seedlings, then two-year-old may be selected, because these are seldom larger than one-year budded trees. The trees should be set fifteen to eighteen feet apart, varying the distance according to variety, soil, and other local conditions, and it is best to place them in rows and at right angles, in order to admit of cultivating both ways, as it is termed, thereby saving as much hand labor as possible. For the first two or three years after planting, all weeds and grass should be kept away from the stems and over the roots, either by frequent hoeing, or covering with a mulch. The best way, perhaps, to prevent the growth of weeds, is to use the land among the trees for some low-growing crops, such as beans, tomatoes, melons or potatoes, then see that the workmen, when hoeing these crops, hoe up the weeds and grass about the trees at the same time. We might reasonably suppose that the most careless cultivator of trees would think of this, but, unfortunately, extended observation proves quite the contrary, and it is scarcely possible to go through any very extensive fruit-growing region without seeing many such instances of neglect. A square yard or more of tough sward is frequently left for years undisturbed about the stems of all the trees in an orchard, while the little annual plants growing near by, and not worth, at an extreme valuation, five cents each, are cultivated with the greatest care.
The first pruning of the trees should be done at the time of transplanting from the nursery rows, as directed on a preceding page, and from the top of the stem only three or four shoots allowed to grow the first season, all others being rubbed off as soon as they appear, or when they have made a growth of two or three inches. These three or four upper branches are to become the foundation of the future head of the tree, and should be allowed to grow unchecked the first season; the next spring cut back one-half to two-thirds of their original length. This pruning will force out strong side or lateral shoots near the base, thus giving a sturdy foundation to build upon later, the pruner keeping in mind that the weaker the growth the more severe should be the pruning. Better leave a few strong buds, from which vigorous shoots will be produced, than a great number succeeded by many feeble twigs. If blossoms and fruit appear on the young two-year-old trees, a limited number may be left to mature, although no considerable crop ought to be gathered before the third year.
In after years a somewhat different system of pruning may be adopted, keeping in view the fact that the fruit buds and fruit are always produced on the young shoots of the previous season's growth, and for this reason an annual renewal of such parts of the tree is absolutely required, in order to secure a good crop on trees of any age. In some localities and countries it may be possible that almond trees produce a crop every year; but this is scarcely to be expected anywhere. Consequently a system of pruning should be followed which will conform to the variations of circumstances and conditions; and this brings us to the consideration of—
The Proper Time to Prune.—If the growth of the trees and their fruiting were always uniform, then we might readily adopt some invariable system and season for pruning; but as we are dealing with uncertainties, our rules must be equally flexible and variable. If the season is favorable, and the trees bloom freely and fruit sets abundantly, we may proceed to prune as soon as the embryo nuts are as large as peas,—but only cutting back some of the largest bearing shoots, and thinning out others here and there, just enough to equalize and evenly distribute the crop through the head of the tree. But in case the frost or cold of winter has destroyed the crop for the season, then as soon as this is discovered, prune and cut back all the shoots and branches sufficient to insure a vigorous growth of young bearing wood for the ensuing year. Under this system of pruning we fix the time as after blooming in the spring, in order to have our work correspond to circumstances and conditions, and where there is a crop in prospect the pruning is comparatively light; but if there is to be no fruit, or but little, then one should aim to produce an abundance of bearing shoots for the following season. In other words, we prune severely in non-bearing years, whether they occur alternately or otherwise; but this system is only applicable to trees like the almond and peach, which produce their fruit on the shoots of the preceding year's growth.
Almonds are usually divided into three groups, viz.: Bitter, hard-shelled, and soft, or paper-shelled. In each there are many varieties, although they are rarely known in market except by the general name of the group to which they belong. If they are soft, hard or bitter, this is sufficient designation for commercial purposes, with, perhaps, the addition of the name of country in which they were grown, or that of the city or seaport from whence exported.
Bitter Almond, Amygdalus communis amara.—The varieties of this group are not specifically distinct, and some have soft, thin shells, while others are thick and hard; but the kernels are very bitter, hence the name. But in the countries where these almonds are most extensively cultivated, as in the South of France, Austria, Spain and Greece, the trees are generally raised from the nut, and, as might be expected, the crop produced under such conditions is exceedingly variable, the nuts being large or small, and the shells of various degrees of hardness, with an occasional tree producing both bitter and sweet kerneled nuts. These wilding trees are, in the main, more hardy than the improved varieties, hence are largely employed as stocks for the better sorts, as well as for the plum and apricot. It is also claimed that, as a rule, the bitter almond trees bloom later in the spring than those of the other two groups, and for this reason are not so liable to be injured by spring frosts. The trees are hardy in all of our most favorable peach-growing regions of the Middle and Northern States, but some of the varieties ripen rather too late for localities north of the latitude of New York city. All this, however, and other obstacles, will soon disappear, whenever the time arrives for our horticulturists to take up almond culture and pursue it with half the zeal they have the cultivation of the peach and many other kinds of fruits.
Hard-Shelled Almond, A. c. dulcis, or sweet-kerneled almond.—The varieties of this group, as a whole, differ from those of the next only in the firmness of their shells, which are moderately firm, with a slightly rough and deeply pitted surface, as shown in Fig. 7. Varieties of this group are fully as large as, and perhaps a little longer than the thin-shelled, and the kernels are fully as valuable when removed and sold as shelled almonds. It may require a little more labor to crack and remove the kernels for market, but the difference is scarcely worth taking into consideration by the grower.
The common sweet, hard-shelled almond thrives in peach-growing regions as far north as Central New York, and I well remember of seeing trees loaded with these nuts, in my boyhood days, in the western part of the State. The late Patrick Barry, in the Fruit Garden, when referring to this nut, says:
"This is a hardy and productive tree, succeeding well in the climate of Western New York, and still farther north. Nut very large, with a hard shell and a large sweet kernel; ripe here (Rochester) about the first of October. The tree is very vigorous, has smooth, glaucous leaves, and when in bloom in the spring is more brilliant and showy than any other fruit tree."
Nearly every one of our noted horticulturists who have said anything about almond culture in the North, agree with Mr. Barry in regard to the beauty of this tree and its productiveness; but it is well to keep in mind that it is no more to be depended upon than the peach, and the barren years will far outnumber the bearing ones. But the almond is probably as certain here as in France, where it is cultivated extensively as an article of commerce, although a full crop once in about five years is about all that is expected. We can probably do much better than this, especially if proper attention is given to the production of new varieties adapted to our climate, as has been done in California with the almond, and here in the East with the peach and many other kinds of fruits; and when such have been secured, proceed to multiply them in the usual mode of budding upon seedling stocks.
Soft, or Brittle-Shelled, A. c. fragilis.—In this group we have many distinct varieties, besides others which are known by local names, but have no permanent and pronounced distinguishing characteristics that would aid in separating them, should this be desired. The most common form, widely known as the sweet-kerneled thin-shelled (Fig. 8), is one of the oldest in cultivation in European countries. The flowers usually appear with the leaves, or before they unfold, and are large and of a pale rose color. The tree is rather tender for latitudes north of Philadelphia, but succeeds southward, and westward to the Pacific, if late frosts do not come to destroy the flowers or embryo nuts.
Large Fruited Almond, A. c. macrocarpa.—This is an old French variety, and perhaps most widely known as the Sultana, although the latter name is often applied in market to almost every variety of sweet almond. The leaves of the genuine variety are much broader than those of the preceding groups, and are smooth and deep green. Flowers very large and showy, of a pale rose color, and always appear in spring before the leaves, and for this reason it has long been cultivated in England as an ornamental tree. Fruit large, depressed or flattened at the base, but pointed at the top. Shell rather hard and firm, and will withstand rough handling and transportation long distances. Kernel very sweet and tender, hence highly prized everywhere. There are several sub-varieties; one, known as the Pistache almond, is highly esteemed for the table, on account of its delicate flavor, although it is very small and not popular for commercial purposes.
The Peach Almond, A. c. persicoides.—This is another old variety, described by Du Hamel about the middle of the last century, under the name of Amandier-Pecher, or peach-leaved almond. Leaves similar to those of the common peach. Fruit ovate, obtuse; husk slightly succulent; shell of a yellowish color, and the kernel sweet-flavored and excellent. Du Hamel says the fruit varies widely, even upon the same tree or branch, some having a dry, thin husk, while on others it is soft and fleshy, somewhat like that of the peach. As the almond and peach are of the same species, it would not be at all strange if an occasional variety raised from the seed of either class should diverge towards, or even pass completely over to a closely allied group.
From the varieties found in the forementioned groups we must seek to find, or produce therefrom, those which will succeed in this country wherever it may be thought desirable to attempt the cultivation of this nut. So far as my knowledge extends, no attempts have, as yet, been made to produce distinct American varieties in the Eastern States, as with its near relative, the peach, but all the almonds thus far cultivated here are of well-known foreign varieties. Perhaps the demand for almond trees has not been sufficient heretofore to encourage very extended experiments in this direction, but I cannot believe that our people will continue for another century to import millions of pounds annually of almonds if it is possible to raise them in this country. That it is possible on the Pacific coast has already been fully demonstrated, but we want to see the field greatly enlarged, and give the people of the Eastern States a share in what is evidently soon to become a large and profitable industry.
Ornamental Varieties of the Almond.—These are only referred to because some of the many in cultivation belong to the groups producing the most valuable nuts, but the greater part of the purely ornamental varieties are worthless for other purposes. Amygdalus cochinchinensis grows to quite a large tree in its native country, or thirty to forty feet high; flowers small, white, produced in long racemes; tender. A. orientalis, a small shrub, with grayish or hoary leaves, and small rose-colored flowers; sometimes cultivated under the name of argentea, or Silvery almond. A. incana (hoary) is another dwarf species, from the Caucasus, with solitary red flowers. A. nana and A. pumila are oriental species of very dwarf shrubs, with either red or white flowers. The double-flowering varieties of these have long been inhabitants of our gardens.
Properties and Uses.—For domestic purposes the almond is highly esteemed wherever it is known, and is employed in hundreds of different ways in the preparation of appetizing dishes and dainties for the table. In countries where this nut is in cultivation, it is brought to the table in the half-opened green husk, for at this time the kernels are just passing from the milky stage, and are considered more readily digested than later, or when fully ripe. But it is only when they are fully mature that they are gathered for market, and after thorough drying they are placed in strong sacks and distributed among dealers in all parts of the world. But only certain varieties are exported in this condition, and principally those with very thin shells, because these are most in demand, for the table and dessert, where the almond is not a home product. Other sweet varieties, whether with very hard or very tender shells, are cracked and only the kernels exported. The importation of shelled almonds into this country is somewhat in excess of the unshelled, and as they are of greater value per pound, the duty levied is proportionally higher. There is also a great saving to the importer and consumer,—not only in freight, but the extraction of the kernels is done in countries where labor is abundant and cheap. Whether the almond shells are used for any purpose in European countries, or are considered as wholly a waste product, I have been unable to learn, but it is asserted, and by men whose word is worthy of credence, that almond shells ground into a fine golden colored flour, is much used in this country for adulterating red pepper, cinnamon and other spices.
Almonds are not only used extensively at all times and seasons, by persons of all ages and sexes, at table and elsewhere, but they are employed largely in the making of fancy confectionery with sugar, or in the form of salted almonds, the kernels having been first thoroughly steamed or scalded, to remove the skin, and then rolled or dusted with fine salt. Prepared in this way they are usually considered more readily digestible and healthful than in their natural state.
Sweet almonds are also valued in the form of emulsions, as a medicine in pulmonary disorders, and the oil of almonds is a common standard article in the stock of druggists everywhere, as it enters into the composition of cosmetics, syrups, pastes and powders of various kinds.
The kernels of the wild bitter almond contain a poisonous principle known as hydrocyanic or Prussic acid, which does not exist in the sweet varieties, although found in their leaves and the bark of their twigs. But as bitter almonds are not palatable, there is little danger of anyone being poisoned from eating them, should these nuts ever be cultivated here for any special purpose, as in other countries.
Insects and Diseases.—Whenever the almond tree becomes common here in orchards it will doubtless suffer from the attacks of the same kinds of natural enemies as affect the peach. One of the most widely distributed of these pests is the common peach-tree borer. The parents of these borers are small, slender-bodied, bluish, transparent-winged moths, the male somewhat smaller than the female. These moths usually appear in this latitude during the month of June, and the female deposits her eggs on the stems of the trees near the surface of the ground, or a little below it if she can find a convenient opening to suit her purpose. The eggs deposited soon hatch, and the young larvæ bore through the tender bark at this point, and when fairly under it, branch off, cutting galleries through the soft alburnum underneath. When a number of these borers are at work on the same tree they sometimes girdle and kill it the first season, especially if it is young or a small specimen. But if the tree is not killed outright it will show, by the check to its growth, that borers are at work. The borers continue feeding throughout the remainder of the season, and up to the time freezing weather sets in for the winter, and if not full grown at this time they will finish their growth early in spring, then crawl to near the outside, or just under the old bark, and there spin a thin cocoon, in which they are transformed to the pupal stage, remaining in this form for a few weeks, then issuing in the winged or moth stage.
In the line of preventives and remedies there is nothing better than clean cultivation about the trees, and annual examination of each tree early in summer and the crushing of every borer found. The next best thing, in the way of a preventive, is to wrap the stems from a little below the surface of the ground to a foot or more above it with heavy paper, cloth, or bark of some kind, to keep the moth from laying her eggs on the bark of the tree. I have used common tar paper for this purpose, not only because it is very cheap and does not decay when exposed to the weather, but the exhalation or odor of tar seems to be offensive to the moths. In the use of this material I have never found that it was in the least injurious to the bark underneath. Painting the stems with soap, cement, clay, or even common mineral paints, will answer very well if a little care is given to keeping down the number of insects by removing the larger part of the borers with knife or gouge.
In recent years a pest known as the "shot-hole borer" (Scolytus rugulosus) has appeared in many and widely separated localities, in both the Eastern and Western States, attacking the almond, peach and plum tree. It is supposed to have been introduced from Europe with imported nursery stock, and thence rapidly distributed, by similar means, through the country. In its perfect stages it is a minute brown beetle, about one-twelfth of an inch long and one-thirtieth of an inch in diameter. This pest appears about midsummer, boring numerous minute holes through the bark and into the sapwood underneath, and in this the female deposits her eggs, and from these are hatched the little grubs found later feeding on the soft inner bark and alburnous matter beneath it. From every hole made in the bark a small globule of gum will soon appear, drying upon the surface—thence onward until autumn—and glistening in the sun, an immutable sign of the presence of a minute but destructive enemy.
When the beetles and their eggs are once in possession there is no practical way known of removing them, and the best thing to be done is to cut down and burn every infested tree, and just as soon as it is known to be in this condition. There are also several indigenous species of bark beetles, which will very likely attack almond trees as soon as they are as abundant as peach trees, but all may be destroyed with the same, or very similar weapons and materials.
What are called preventives consist mainly of substances to be applied to the stems in a semi-liquid form, and of such a nature as to be offensive to the beetles because of their odor, taste, or because so hard that the insects cannot cut through them with their mandibles. Common lime whitewash, soft soap, whale-oil soap, or a thin mineral paint made of pure linseed oil, will answer very well for this purpose if applied often enough to keep the bark constantly coated.
Of the fungous diseases affecting the almond in this country, very little is as yet known, although we may safely include under this head all those that have been inimical to the peach, for the transition from this tree to the almond would only be a natural sequence. The peach-leaf curl (Taphrina deformans) would not be far from home on the almond leaf, neither could we expect that almond orchards would be wholly exempt from that mysteriously distributed and uncontrollable disease known as "peach yellows."
In California an almond-leaf blight has already appeared and seriously affected the trees in some of the orchards. It is caused by a fungus known as Cercospora circumscissa Sacc. This fungus attacks the leaves and young twigs, causing the former to fall off early in the season, thereby checking the growth of the tree and preventing the maturing of the fruit. It is thought that remedies may be applied to check this disease, and there will probably be some form of copper solution employed for destroying it, as with various species of fungi on other kinds of fruit trees.
Fagus, Linn. The Beech. The Latin name of the genus (Fagus) supposed to be an equivalent of the Greek phegos, an oak, or it may be derived from phago, to eat; the nuts of this tree having been used as food by man in all ages and countries where it is a native. The modern English name, beech, was probably derived from the Anglo-Saxon bece or boc; in Dutch it is beuk; French, hetre; Icelandic, beyk; Danish, bog; Swedish, bok; German, buche or buoche; Russian, buk; Italian, faggio; Armenian, fao; and in Welsh ffawydd.
The beech belongs to the order Cupuliferæ, or oak family. The genus contains about fifteen species of handsome deciduous and evergreen trees, or shrubs, very widely distributed throughout the temperate and colder regions of both the northern and southern hemispheres. Male flowers are bell-shaped, in long-stalked drooping heads; calyx five to seven cleft, containing numerous stamens. Female flowers two to four in a cluster on the summit of the scaly-bracted peduncle; the inside scales uniting, forming a four-lobed involucre of imbricated bracts, the whole becoming at maturity a somewhat prickly, scaly bur, within which are found a pair of sharp-edged triangular nuts, containing a tender and sweet-flavored kernel.
History of the Beech.—The common beeches of both Europe and North America are so closely related that the two species may be considered as one for all practical purposes, such as propagation, cultivation, and value of the wood and nuts. It is true, however, that our native beech is not environed with ancient myths and stories of love and war, neither is it celebrated in poetry and song, yet it has, doubtless, played just as noble a part in human affairs among the pre-historic races of America as those recorded of its European contemporary. As the beech in Europe is found in the forests of Great Britain, Norway, Sweden, France, Germany, and southward to Constantinople, Palestine, Asia Minor and Armenia, it was well known and highly appreciated by all the early inhabitants of these countries, and is frequently referred to by the earlier writers of Greece and Rome who touch upon the rural affairs of their times. It is supposed that Theophrastus refers to the beech under the name of Oxua, and Dioscorides as Phegos, and the latter author places it among the oaks, in which he was not far out of the way, because the beech is a member of the oak family in our modern classification. Virgil and Pliny speak highly of the little triangular nuts, and the people of their times set considerable value upon beech-nuts as an article of food. Pliny also assures us that at the siege of Chios, the besieged inhabitants lived for some time entirely on these nuts. We are inclined to think, however, that both Virgil and Pliny are in error when they tell us that the beech was propagated by being grafted on the chestnut. They were probably led astray in this by some romancing gardener of their time, for we even have some of the same ilk with us at this day. Pliny refers to the beech several times in his writings, and places a much higher value upon this nut than he does upon the chestnut; in fact, speaks rather contemptuously of the latter, and seems to be surprised that nature should have taken such care of the nuts, which he calls "vilissima," as to enclose them with a prickly involucre or bur.
But my limited space will not allow of tracing the history of the beech from ancient to modern times, although it has always been esteemed as food for man, as well as for wild and domesticated animals. Swine fattened on beech and oak mast have for ages been noted for their excellent flesh, and the value of many an old estate in Great Britain was determined more upon the mast the forest produced, than the area or number of square miles they contained.
As a monumental tree the beech has no rival, for its smooth gray bark, perennial and almost unchangeable, has ever been a convenient place to register challenges to enemies, epitaphs, epithets, and probably more frequently than all, the initials of the name of some loved one, who might possibly pass that way and find her name engraved on the beechen tree. I doubt much if there is a beech grove in all Europe or in America, within a convenient distance of a city, country village or schoolhouse, on which the bark of the trees is not scarified by the knives of boys in recording the initials of their own names, and those of their favorites of the opposite sex. These living registers were long ago recognized by the poets, and more than eighteen centuries ago Virgil admits it in these lines:
"Or shall I rather the sad verse repeat,
Which on the beech's bark I lately writ."
In more modern times Tasso hints of the same habit, in Jerusalem Delivered, to wit:
"On the smooth beechen rind, the pensive dame
Carves in a thousand forms her Tancred's name."
That the Spanish youths were not oblivious to their opportunities for recording the names of their favorites we must assume to be true, from the lines of Don Luis de Gongora, who tells us that:
"Not a beech but bears some cipher,
Tender word, or amorous text.
If one vale sounds Angelina,
Angelina sounds the next."
Propagation of the Beech.—The beech, in all its species and varieties, may be propagated by the usual modes, viz.: By seed, layers, budding and grafting. The seeds, when gathered, should be mixed with clean, sharp, moist sand, placed in boxes, and then stored in a cool or cold place and carefully protected from mice, until the time arrives for sowing in spring. They may also be sown in the fall and lightly covered with leaf mold or other light soil, but unless coated with tar or some offensive poisonous substance, vermin of some form will be very likely to find them and leave few to grow. Seedlings are used for stocks upon which to work the many varieties in cultivation; but as I am not writing this for the encouragement of propagators of purely ornamental trees, I will omit giving any very extended description of the different modes of propagating the beech, further than to say that should remarkably fine varieties with extra-sized nuts be discovered or produced, they can be perpetuated and multiplied by the same processes adopted for other kinds of nut trees.
Soil and Location.—The beeches of Northern countries, in their many varieties, thrive best in a cool, moist soil, for their roots rarely penetrate very deeply, but spread out widely and near the surface, forming an intricate network, which will try the patience of the woodman who attempts to clear away a forest of beech and break up the ground. In this country, as well as in Europe, the beech thrives in calcareous soils, or what is usually termed limestone regions; consequently, when transplanted or raised in sandy soils, or on the red sandstone formation, light applications of lime are usually found very beneficial; but more than all, the beech requires moisture, and if not planted in a moist soil the surface over the roots should be kept constantly covered with some kind of mulch.
Species and Varieties of the Beech.—In the Dictionary of Gardening, edited by George Nicholson, of the Royal Botanic Gardens, Kew, England, the following species of Fagus are briefly described, viz:
F. antarctica.—Leaves ovate, blunt, glabrous, attenuated at the base, doubly dentate, alternate, petiolate, one and a half inches long. A small deciduous tree or shrub, with rugged, tortuous branches. Native of Tierra del Fuego, S. A.
F. betuloides (birch-like). Evergreen beech.—Leaves ovate, elliptic, obtuse crenulate, leathery, shining glabrous, round at the base or short footstalks. An evergreen tree, native of Tierra del Fuego, S. A.
F. ferruginea (rusty). American beech.—Leaves ovate, acuminate, thickly toothed, downy beneath, ciliate on the margin. A large deciduous tree, very closely resembling the common European species, from which it is distinguished by its longer, thinner and less shining leaves.
F. obliqua (oblique). Chile beech.—Leaves ovate, oblong, oblique, somewhat rhomboid, blunt, doubly serrated, entire at the base, attenuated into the petiole, and somewhat downy. A hardy deciduous tree, native of the cooler elevated regions of Chile, S. A.
F. sylvatica (sylvan). European beech.—Leaves oblong, ovate, obscurely toothed; margin ciliate. A well-known large deciduous tree, widely distributed in Europe from Norway southward to Asia Minor. From this species a large number of ornamental varieties have been produced, many of them merely accidental variations of the wild forms of the forests, while others have originated in the seedbeds of nurserymen. But so far as I am aware, no variety has ever been introduced bearing superior or improved forms of nuts.
Our American beech (F. ferruginea) is a widely distributed tree, extending from Nova Scotia in the north, south to Florida, and westward to Wisconsin and Missouri. Formerly it was exceedingly abundant, but like many other of our most valuable forest trees, it is disappearing before the axe of the woodman, who has always found a ready sale for beech timber. It is used in the manufacture of plane stocks, shoe lasts, handles for paring chisels, and hundreds of similar articles. Beech wood is hard, firm, and takes a good polish, but is not very flexible. It makes excellent fuel, and ranks next in value to hard maple and hickory for this purpose. In the more northern States and where the beech grows to its largest size, the heartwood is usually of a reddish color; but here in New Jersey and farther south, the wood is usually white almost to the center of the tree, no matter how large it may be. The color of the wood, however, does not in any way detract from its value, for fuel and many other purposes, although some European dendrologists have been deceived into supposing that the white beech was almost or quite worthless. Loudon, in Arboretum et Fruticetum Britannicum, Vol. III, in referring to our beech, says: "The wood of the white beech is little valued in America, even for fuel; and the bark is used for tanning, but is little esteemed," etc. But if any one, in these later years, has had occasion to purchase beech timber for any purpose, he has probably learned, from the price charged, that it is esteemed, even for such base purposes as firewood.
I am not, however, attempting to extol the American beech as a timber tree, but ask that it be given a place among the select ornamental nut-bearing kinds. And I think every farmer who has a pasture lot could afford a place for at least one beech tree, and if there is a low, moist spot in the field, or a stony corner, this will be a suitable place for such a tree; and the horses, cattle or sheep out in pasture during hot days in summer will be very grateful for the shade which a wide-spreading specimen will give them. It may be that the owner of said pasture may recall the lines of Garcilaso:
"But in calm idlesse laid,
Supine in the cool shade
Of oak or ilex, beech or pendant pine,
Sees his flocks feeding stray,
Whitening a length of way,
Or numbers up his homeward-tending kine."
He may be sure of one thing, and that is, the beech-nuts produced by one or many trees will always be acceptable to the children, and of these hungry mortals there is likely to be a few, at least, roaming about in ages to come, as in times past.
The beech is not really a desirable tree to plant on a lawn or near one's dwelling, because of its persistent foliage, which clings to the twigs very late in winter, and the rustling of the wind through the dry leaves is not soothing to one's nerves, although not quite as dismal as the moaning pines. In summer, and until late in autumn, the American beech is a noble and graceful tree,—and if I may be allowed the expression, one of the cleanest of trees; its large, thin, bright-green and glossy leaves retain none of the dust and cast-off material of other trees which may be floating through the air, but are ever bright and pure. The tree has naturally wide-spreading and somewhat drooping branches, and should be given plenty of room for development when planted for the nuts or as an ornamental tree. Its leaves and the small slender branchlets (Fig. 9) are eaten with avidity by all kinds of farm animals; consequently, protection may be required until the trees have reached a hight to be safe from such depredators.
Beech seedlings do not usually come into bearing in less than twenty to thirty years, but as no one in this country has ever attempted to cultivate this tree for its nuts, or search our forests for precocious and superior varieties, we have to admit that the field remains unexplored, and as barren of results as it was when our ancestors first discovered America. Every hunter, woodman, farmer and botanist who has roamed through forests where the beech trees grow, is well aware of the fact that distinct varieties are not at all rare, some having nuts twice the size of others in the same woods or groves, and it is possible and probable that some nut culturist in the near future will find time to select these choice wild varieties for cultivation and propagation. It would not, in my opinion, be beneath the dignity of our national department of agriculture, or some of its numerous costly annexes, to occasionally take into consideration the natural products of this great country, and determine, by a series of experiments, whether or no they were not worthy of attention.
