The maxim of Oliver de Serris is much better founded. " Le bien labourer, le bien fumer, est tout le secret de 1'agriculture." Till well and manure well is the whole secret of agriculture. MANURES. 59 The elementary parts of these manures, as ex- hibited in this table, sufficiently indicate the mode of preserving them. When dropped in the fields and in small parcels by cattle, they exhibit no signs of fermentation, nor undergo, in that state, any degree of chymical decomposition ; but, when brought to- gether, and frequently wetted and subjected to the action of atmospheric air, they are speedily dis- solved and give out much gaseous matter. To pre- vent the escape of these soluble and volatile parts, two things are necessary : 1st, that the dung be col- lected in a reservoir of convenient size, and walled and paved with stones ; and, 2d, that a layer of sand or earth be occasionally spread over the surface of the dung. The former will prevent filtration, and the latter retain the gaseous matter so useful in vegetation, and, at the same time, augment the quan- tity of manure. To prevent an excess of moisture, which always retards, and sometimes prevents de- composition altogether, the reservoir should be covered. The application of manures is a subject of more difficulty, and has given occasion to some dispute. The controverted points are, 1st. Whether short or long dung, or, in other words, whether dung thoroughly rotted, or that which has but begun to rot, is most advantageous. 2d. Whether dung used superficially, or ploughed deep into the ground, is most profitable. 3d. Whether extraneous matters admitted into the dungheap are useful or otherwise. 4th. Whether stable manures are best applied di- rectly or indirectly to wheat crops. 5th. At what time manures are best applied ; and, 6th. In what quantity. We shall discuss these points separately and briefly; and, 1st. Which is to be preferred, long or short dung ? The discordance in practice, as well as in opinion, 60 AGRICULTURE. prevailing on this question, induced some scientific men to institute a series of experiments, having for their object a full and regular solution of it. With this view, parcels of dung (long and short) were taken from the same stables on the same day, and applied to crops of the same kind growing on the same fields. The result perfectly conformed to the- ory, and was similar in all the experiments. Those parts of the field to which the short dung was ap- plied gave the best crops the first year ; but those on which the long dung had been laid gave the best crops the second and third years ; a fact which au- thorizes the conclusion, that, if we wish to obtain one great crop, the rotted dung is best ; but when we look to more permanent improvement, the long dung is to be preferred. 2d. Which is the better practice, to spread ma- nure on the surface, or lay it deeply under the ground T In favour of the former practice it has been con- tended, that the distribution of the dung could be more equally made on the surface with a spade than under ground with a plough;* and for the latter, that all tap-rooted plants, entering far into the earth, require it to be laid deep ; while those with fibrous roots will be sufficiently benefited by its exhalations. Both modes, however, are obviously bad. We have seen in the preceding article that dung, to become the aliment of plants, must under- go a decomposition ; and that, to the production of this, the combined action of air and water is indis- pensable. But, if the manure be buried deeply, this action cannot reach it, and the dung remains a ca- put mortuum. On the other hand, if spread super- * The English are said to have a machine attached to the drill that goes before and distributes the manure at the neces- sary depth. In planting potatoes we make a bed of dung for the plant. Why not apply the same reasoning and the same practice to all seeding of the ground 1 MANURES. 61 ficially, the rains dissolve and carry away many of its juices, while the sun and the wind evaporate the rest. These considerations lead to the true rule on this head, which is to lay it three or four inches be- low the surface of the soil. At this depth, if short dung, its action will be most vigorous in all direc- tions ; and if long dung, a greater depth will, as al- ready suggested, completely destroy all action. 3d. Are extraneous matters, as horns, hoofs, bones, shells, feathers, leaves, weeds, &c., &c., to be admitted into the dung-heap ? There is, perhaps, nothing in either theory or practice so obviously right, that it may not be dis- puted. The principal objection made to these mat- ters is, that they do not decompose equally ; and that those ingredients of the heap which are slow- est in decomposition, retard others, which, if left to themselves, would be more forward in this process. This objection is without weight ; for we have seen that long or unrotted manure, though its effect be prompt, is, upon the whole, more favourable to cul- ture than that which is rotted. The difference 'of time in decomposition is therefore no evil, and the augmentation of the mass is a great good ; besides that, some of these offals are the most powerful manures. Horns and hoofs are compounded of al- bumen and gelatine ; bones, of the phosphate and carbonate of lime and gelatine ; shells, of carbonate of lime and animal matter ; and feathers and hair, of albumen, oil, &c., &c. Applied to the roots, they forward the growth of fruit-trees more than any other species of manure. 4th. Whether stable manures are best applied, directly or indirectly, to wheat crops 1 The practice, on this head, is different in different places. In France, as in all other countries where fallows are in use, the dung is applied directly to the wheat crop ; while in England, where the rota- tion system is established, it is applied to the sum- F 62 AGRICULTURE. mer crop, which immediately precedes that of the wheat. The objection to the French practice is, that the weeds brought into the field by the manure start with the grain, and do as much harm as the dung does good. Nor is there any sufficient answer, that I know of, to this objection. The English practice is, therefore, much to be preferred ; because, besides the advantage of exchanging a fallow for a summer crop, it permits you, while that crop is growing, to destroy the weeds that otherwise would have infest- ed your fields. 5th. At what time of the year are manures best applied ? The most approved rule on this head is to apply the winter dung wholly to potatoes, flax, and corn ; that of the spring, to cabbages and beans ; and what may be afterward collected, to turnips ; and, 6th. In what quantity ought we to apply them ? The quantum of manure to be applied to the acre must necessarily depend on the staple of the soil. If entirely exhausted of vegetable mould, a great deal will not be too much ; but there is a possibility of erring in this respect, even with regard to poor soils. Where an excess of manure exists, the crop, whatever it be, runs into stalk and leaf, and the effect on the flavour of the vegetable is bad ; a fact which the experience of all who have tasted the cabbages and turnips raised in the poudrette of Paris and London can abundantly establish. Even mead- ows, which are least liable to injuries in this way, may be too much dunged. What cultivator of ob- servation has not seen his cattle turn with disgust from herbage the most luxuriant in appearance, but growing out of masses of manure ? This circum- stance suggests the advantage of going over our meadows in the fall, and breaking up and distribu- ting such lumps of dung as may be found in them. The preceding remarks were confined to stable MANURES. 63 manures. What remains to be said applies to lime, marl, vegetable ashes, ashes of earth, and green crops ploughed into the ground. It will be remembered that the action of lime, as a manure, is owing to its causticity, or power of dissolving animal and vegetable substances ; and to its quality of absorbing carbonic acid from the at- mosphere. These properties render it peculiarly useful in composts, or mixtures of dung, peat, and earth; a mass of which, disposed in alternate lay- ers, is no doubt the perfection of this branch of husbandry.* It is also applied without any acces- sary, and with great advantage, to marshy grounds ;f to those having in them the remains of shellfish ;J to natural meadows, and to all soils abounding in vegetable mould. On those of a different character it must be cautiously used as to quantity, and, in- deed, on any soil, an excess of it will completely destroy the fertilizing principle ; an effect constant- ly observed near mortar beds. The time of using it is liable to less uncertainty. On wheat it should be sown as soon as the grain shows itself, and on meadows late in the fall, and after the cattle have been turned off. Marl, being a compound of clay and lime, has the properties of the latter, and produces similar effects, but in a smaller degree. Hence it is that the quan- tity of it given to the acre is much greater than that of lime. The English practice is to spread it over a field to the depth of three or four inches. This is done late in the fall, to the end that frost and rain may break down and pulverize it. The properties of ashes, whether derived from the combustion of animals, of vegetables, or of fossil * These might be formed in narrow lintals, inclining from the stable. f After they have been drained. j There is much of this description of land on the bays and creeks of the Chesapeake. 64 AGRICULTURE. coal, are nearly the same, and resemble those of lime and marl. They powerfully attract and hold moisture and carbonic acid, and they hasten the de- composition of stable manures, or other vegetable or animal product. Their action is most favourable on wet and cold soils, and as a top-dressing to nat- ural meadows and turnip crops. The practice of paring and burning the surface of the earth has been much used, and warmly recom- mended by the Irish ; and in their land of bogs, as in the marshes of Holland, where infertility arises from excess of vegetable matter, it may be useful; but to burn the surfaces of sandy, gravelly, or even of dry clay soils, would be to lose sight of all sound theory. Soils in general may be divided into two kinds, sand and clay. The defect of the one is want of cohesion between its parts ; that of the other, an excessive or superabundant cohesion. But vegeta- ble matter is, as we have seen, a remedy for both ; and to accumulate this is the constant endeavour of every enlightened agriculturist. Yet are we advi- sed to destroy this vegetable matter by fire, and to substitute for it a small portion of ashes, as more favourable to vegetation than the soil itself! But in what will these ashes differ from those found in our chimneys, and of which enough may be had T In nothing, excepting that they may possess some- what more alkaline salt ;* a circumstance which, if the subsoil be not charged with oily and animal mat- ter, will be more injurious than useful. * De Saussure's experiments prove, that the stems of trees (other things being equal) produce less of this salt than the branches, the branches less than the twigs, and the twigs less than the leaves. M. Perthuys has formed a table of the relative alkaline products of plants and trees. By this table it appears that the leaves and stems of Indian corn give to the quintal eight pounds thirteen ounces, those of oak one pound five ounces, and those of pine five ounces. MANURES. 65 But, besides the consideration of getting so lit- lle, and that little of such equivocal character and use, what do we lose by the process 1 If we ap- proach these little kilns, we find them emitting a black smoke, which cannot be entirely consumed ; and our eyes and noses are assailed by some stim- ulating and ammoniacal matter, which is fast es- caping, and which so far alters the atmospheric air in the neighbourhood as to render it difficult of respiration. Need we add that this is the animal, oily, and gaseous matter essential to the vegetable, and highly important to vegetation! It may be that the ashes obtained may give one or two good crops of turnips; but even the advocates of this practice admit that, " it ruins the land for an age ; and hence it is that in England, tenants are restrain- ed from paring and burning, especially towards the close of their lease."* Clay burning is a different operation, and made with different views ; not for the production of ash- es or salts, which may operate chymically, but merely (by the application of heat) to alter the tex- ture of the soil ; to give to it an artificial division and porosity ; to render what was cold warm, what was wet dry, and what was compact granular. But a small degree of heat will not produce these effects ; for, unlike the stems and roots of plants, clay is not itself combustible ; and, to bring it to the brick state, the heat applied must be long, contin- ued, and great : hence it follows, that the practice becomes objectionable on the score of expense, and the more so as burned clay has no possible advan- tage over the much cheaper substances of sand, gravel, and pounded limestone. The operation of all is merely mechanical, and exactly in proportion to the quantity used. Our partiality for green crops ploughed into the * See Cobbett, part second, p. 168, " Year's Residence in the United States." F 2 66 AGRICULTURE. ground as manure has been sufficiently indicated, and it is now only necessary that we mention the plants best calculated for this purpose. At the head of these we place buckwheat, as well on account of cheapness as effect : cheapness, because the price of the seed, which is the only additional expense, is below consideration ; and effect, because this plant, while growing, is, from its umbrageous form, a great improver of the soil, both by stifling weeds and preventing evaporation ; and, when ploughed into the ground, none decomposes more rapidly, nor has any a more powerful effect in keeping the earth loose and open to the action of light, heat, air, and moisture, all of which are indispensable to vegetation. " I know no plant," says Rozier, the great French agriculturist, " that furnishes a better manure, or which is sooner reduced to vegetable mould, than buckwheat." When cultivated with this view, the usual quantity of seed ought to be in- creased, and the time of sowing hastened, so as to enable you to have two crops of manure the same season, and before the sowing of wheat. The lupine (one of the leguminous family) has been long and profitably employed as a manure in Spain, Italy, and the southern province of France. Columella directs that " it be sown in September, about the equinox, so that it may attain, before winter, a growth that will enable it to resist wet and frosty weather, which it particularly dreads." I need not remark that these directions are not cal- culated for this climate, and that the seed-time for the lupine here is the 20th of May. The properties which recommend it as a manure are nearly the same as those which belong to buckwheat. It is a quick grower, and has numerous, large, and succu- lent leaves. While growing it subsists principally upon the air, and, when buried, decomposes entirely and rapidly. The pea tribe has the next place in this list ; but, TILLAGE. 67 though not better adapted to the end than buck- wheat or lupine, it is more capricious than they, and requires a soil of better staple and more prepara- tion. The seed is also more expensive. Of this tribe the yellow vetching (lathyrus pratensis) is the species to be preferred. Turnips have been cultivated in England with the same view, but the practice has yielded to another and better (which, however, is not suited to our climate), , feeding them off in the winter and on the field. CHAPTER VII. OF TILLAGE, AND THE PRINCIPLES ON WHICH IT 18 FOUNDED. TILLAGE has three objects: 1st, the raising of plants, whose seeds, stems, or roots may be neces- sary or useful to man and the animals he employs ; 2d, the improvement of the soil, by laying it open to those atmospheric influences which increase its fertility ; and, 3d, its destruction of weeds or plants which rise spontaneously, and are either altogether unfit, or fit only in a small degree, for the nutrition of men and cattle, and which, if left to themselves, would stifle or starve the intended crop. In fulfilling either or all of these objects, it is evi- dent that the surface of the earth must be broken and divided into small parts, so that it may furnish a bed and covering for the seeds sown, enable the plants to push their roots into the soil, and draw from it a portion of their subsistence. To accomplish this leading intention, the division of the soil, various means have been employed. Fos* 68 AGRICULTURE. sil, animal, and vegetable manures, as well by their mechanical action as by their chymical properties, promote it; as do sand, pounded limestone, and water, as in the culture of the rice ; but it is to the spade and the plough we must look for that degree of efficiency, without which the earth would have remained a desert, or would become one. Of these, where the scale of labour is small, as in garden cul- ture, the former is to be preferred ; but, in farm- ing, the greater expedition of the latter gives it a decided advantage. Our remarks, therefore, will be confined to the operations of this instrument ; and particularly to such as have given occasion to dif- ferences in opinion among practical farmers. 1st. At what season of the year, spring, summer, or fall, is ploughing best performed, in relation to division and improvement of the soil, and the destruction of weeds ? The more scientific opinion is in favour of fall ploughing ; because to the action of air and moist- ure it adds that of frost, whose septic or dividing quality is second only to that of the plough itself. In clay soils this preparation should never be omit- ted ; because on those the action of frost is great- est, and because one ploughing of this kind may save two in the spring, when time is everything.* In this operation, however, we must not forget to ridge as well as plough; and care must be taken that our furrows have sufficient declination to car- ry off surplus water. With these precautions, clay ground will be ready early in the spring for another ploughing ; and the decomposition of the sod and weeds turned down in the fall will be nearly, if not altogether, complete.! * The marsh bean grows best on a fall ploughing ; and oaf*, well harrowed, will, on such ploughing, give a good crop with- out other culture. f Without water there is no decomposition, and much water checks and prevents it TILLAGE. 69 In dry and warm soils' these advantages are less ; but still the time gained for spring work is a suffi- cient inducement to a practice that economizes, not merely labour, but the productive powers of the earth also, by soonest enabling us to shade the soil with a growing crop.* 2d. What number of ploughings, preparatory to a crop, is necessary or proper ? The Romans were in the practice of multiplied ploughings. This appears as well from the precepts of Cato as from the opinion of Columella, that " til- lage, which does not leave the earth in a state of dust and render the use of harrows unnecessary, has not been well performed." Tull and his disci- ples carry the doctrine still farther, and believe that frequent ploughings enable us to dispense with even the use of manures. This, however, is extravagant : it is certain that the plough can do much, but it is equally certain that there is much it cannot do. Agriculture, like other business having profit for its object, is a subject of calculation ; its labour must be regulated by its end ; and the moment the expense of this transcends the profit, it may be improvement, but it ceases to be farming. When, therefore, we hear of six ploughings preparatory to a wheat crop, we conclude either that the plough will soon stop, or that it belongs to one of the dilettanti, who thinks it beneath him to count the cost. In our own prac- tice, we find that spring crops of the cereal gramina succeed best on one fall ploughing, well ridged and furrowed, and with one cross-ploughing in the spring; and that spring and summer crops of the * Those who have any doubts about the importance of shade, have but to look at the effects of a brush-heap, or other collec- tion of small bodies admitting air, heat, and moisture, during the spring or summer months. Under such collections he will find a much more vigorous vegetation than in the uncovered parts of the field : the cause of this effect is that the brush pre- vents evaporation. 70 AGRICULTURE. leguminous and cruciform families form the best possible preparation for winter crops, and render unnecessary more than one additional ploughing. After all, any proper answer to this question must necessarily be qualified by considerations of soil, weather, season, crop, and culture ; influences which cannot but exist in all cases, and over which we have no control. Wheat, for instance, requires more preparatory ploughing than rye, and rye more than oats. Clay ground demands more tillage than calcareous earth, and calcareous earth more than sand. Wet or dry weather makes frequent plough- ings, according to circumstances, either useful, in- jurious, or impracticable ; and the shade of a horse- hoed crop is, perhaps, in itself, of more importance to that which succeeds, than would be the fallowing of a whole summer. 3d. What depth of ploughing is most to be recom- mended ? This question, though less complicated than the last, requires, like it, an answer qualified by circum- stances. Tap-rooted plants require deeper tillage than others : fall ploughings may be deeper than those of spring, and spring than those of summer. If the vegetable soil be deep, deep ploughings will not injure it ; but if it be shallow, such ploughings will bring up part of the subsoil, which is always infertile, until it receive new principles from the atmo- sphere. " They who pretend," says Arthur Young, " that the underlayer of earth is as proper for ve- getation as the upper, maintain a paradox, refuted both by reason and experience." Where, however, it becomes part of your object to increase the depth of the surface soil, deep ploughing is indispensable ; and in this, as in many other cases, we must submit to present inconve- nience for the advantage of future benefit. But even here it is laid down as a rule, that, " in proportion as TILLAGE. 71 you deepen your ploughings,you increase the necessity for manures."* " From six to eight inches may be taken as the ordinary depth of sufficient ploughing."! And, 4th. Of the different modes of ploughing (level or ridge ploughing), which is to oe preferred ? This question admits no absolute answer. We have already suggested the use of the latter mode in stiff, heavy, wet clays ; and, in our opinion, all ground in which clay predominates, whatever be the culture, should be made to take this form: be- cause it powerfully tends to drain the soil, and car- ry off from the roots of the growing plants that su- perfluous water, which, left to itself, would seri- ously affect both the quality and the quantity of their products.J In sandy, porous, and dry soils, on the other hand, level ploughing is to be prefer- red ; because ridging such soils would but increase that want of cohesion which is their natural defect. A loamy soil, which is a medium between these two extremes, ought, in a dry climate, to be culti- vated in the flat way, that it may the better retain moisture ; and in a wet climate, in ridges, that it may the sooner become dry. * Young. t Idem. $ It has been objected to ridge ploughing that it accumulates the good soil on the crowns of ridges, and impoverishes the sides and furrows. These objections are obviated by narrow and low ridges, which alternate every crop with the furrows. 72 AGRICULTURE. CHAPTER VIII. • OP A ROTATION OP CROPS, AND THE PRINCIPLES ON WHICH IT IS FOUNDED. To this branch of our subject we invite particu- lar attention ; because, in our opinion, it forms the basis of all successful agriculture. Whatever pains we take, whatever expenses we incur, in collecting instruments of husbandry, in accumulating and ap- plying manures, and in tilling the earth, all is to little purpose, unless to these we superadd a succes- sion of [crops, adapted to the nature of the soil, to the laws of the climate, and to the physical character and commercial value of the article raised. Pease will vegetate on wet cotton, and wheat in pure sand ; Indian corn will grow in high northern latitudes, and the apple may be found near the equator. We have seen sainfoin struggling in wet clay, and aquat- ic plants on the top of an arid mountain ; but all indicated the violence done to nature, and present- ed only specimens diminutive in bulk and deficient in quality. The influence of markets on the value of produce is as little to be denied as that of soil and climate. In the neighbourhood of great cities table vegetables are of much more value than wheat or rye ; but, remote from markets, wheat and rye have the advantage, because, being more valuable in proportion to bulk and weight, they bear better the expense of transportation. With this general view of the subject, we pro- ceed to examine, 1st, the practice of Europe ; and, 3d, the rotation best adapted to our own soil, merid- ian, and markets. And, 1st. Of the practice of Europe. ROTATION OF CROPS. 73 It was long since discovered* that the soil, when left to itself, was never either exhausted, or tired, or idle ; but that, however stripped or denuded by man and the animals he employs, it hastens to cover itself with a variety of plants, of different and even opposite characters ; that some of these have a ten- dency to render the earth more compact, while others have the effect of opening and dividing it ; that some, from peculiar structure of roots, stems, and leaves, derive most of their nourishment from the earth ; while others, differently formed, draw it principally from the atmosphere ; and, lastly, that in these voluntary products there is a continual and nearly regular succession of plants differently organized. These observations, carefully made and no longer doubted, and others leading to the same or similar conclusions, first suggested the useful- ness of taking nature as our guide, and of conform- ing our artificial crops to the rules which obviously governed her spontaneous productions. The effect was such as was expected, and for more than half a century the rotation system has formed the true test of agricultural improvement in every variety of soil and climate. Whenever it has been adopt- ed, the art is found in a state of prosperous progres- sion; whenever neglected or rejected, it is either stationary or retrogade. Yet, in the face of a fact, carrying with it such conclusive evidence, the bulk of agriculturists continue to resist this cheap and obvious means of improvement, and pertinaciously adhere to a system (that of fallows) which con- demns to annual sterility one fourth part of the earth; and which prefers four months' unproductive labour to abundant harvests and nutritious crops ! * Virgil, who was a philosopher as well as a poet, appears to have thoroughly understood this branch of natural history : " mutatis quiescunt fcetibus arva." The true repose of the earth is in a change of its productions. 74 AGRICULTURE. But from this display of folly let us turn to one of wisdom. On the rotation system, the whole arable part of a farm is divided into four, six, or eight fields, and subjected to a course of crops denominated,, accord- ing to the number of these divisions, the short, the medium, or the long course. In constructing these courses, however, whether long, middling, or short, the utmost attention is paid to the nature of the soil, viz., in all soils more wet than dry, more com- pact than porous, more bard than friable, the course is made up of the following plants : Wheat, oats, buckwheat, the graminal grasses, beans, vetchling*, clover, cabbages, and chicory. In soils of an oppo- site character, dry, porous, and friable, the plants from which to choose are rye, spelts, barley, pota- toes, turnips,* lupines, Indian corn, clover, sainfoin, and many of the pasture grasses. In loams, which are nearly an equal mixture of sand, clay, and decom- posed vegetables, the choice of plants is much en- larged ; embracing what is more peculiarly proper for both sand and clay, and having, besides, the fol- lowing plants from which to select: Rice, millet, sorghum, or African millet, lucerne? indigo, co-tton, hops, tobacco, madder, hemp, flax? &€.., &c.. The fol- lowing cases will sufficiently illustrate the princi- ples on which they rest, viz., Never to- select for a crop plants not adapted to the soil ; and never, in any soil, to permit two crops of the same species or kinds to follow each other. 2d. Of the rotation best adapted, to our QWH soil, meridian, and markets. Previously to entering upon this subject,, it may not be amiss to glance at the practice hitherto prev- * We here speak of the white turnip. The Ruta Baga, or Swedish turnip, is classed by French agriculturists among the products of strong, substantial clay soils. In the next chapter we shall speak of the culture of some particular plants, and, among these, of the Swedish turnip. ROTATION OF CROPS. 75 alent among us. What this was in 1801 may be seen in the answer of an English gentleman and traveller (Mr. Strickland) to certain queries of the British Board of Agriculture in relation to the state of husbandry here. After remarking that New- England was not a corn country, and had little to do with the plough, and that New- York was then, and would continue to be, the granary of America, he proceeds to divert his British readers with the fol- lowing details : A< The usual course of crops in this state (New-York), is, first year, maize (Indian corn) ; second, rye or wheat ; third, flax or oats ; and then a repetition of the same as long as the land will bear anything ; after which it is laid by to rest. A Dutchman's course on the Mohawk is, first year, wheat ; second, pease ; third, wheat ; fourth, oats or flax ; and, fifth, Indian corn. In Dutchess county the rotation is, first, wheat ; second and third, pas- ture without seed-; and, fourth, Indian -corn, or flax, or oats, or mixed crops.4' Jersey, Pennsylvania, Delaware, and Maryland may be classed together, from a resemblance of climate, soil, and -mode of culture ; and here we have, " first year, Indian corn ; second, wheat ; third and fourth, rubbish pasture. Clover is, however, beginning to be introduced in some such course as the following : First, wheat ; second, Indian corn ; third, wheat ; fourth and fifth, clover." Two exceptions are noticed, however, to this system : 1st. In the German settlements in Penn- sylvania, where, from more attention or more skill, " the wheat crop averages eighteen bushels to the acre, where twenty-Jive bustiels are frequent, and instances of thirty not wanting : andj'Sd. In the pen- insula of Maryland and Delaware, where the rota- tkxn of Indian corn, wheat, and rubbish pasture has reduced the average produce to six bushels per acre ; in some instances not more than two bushels are obtained,* and much is so bad as to be ploughed up 76 AGRICULTURE. " In Virginia the usual crops are Indian corn and wheat alternate!}*-, as long as the land will produce them ; and, in parts where tobacco is cultivated, several crops of it are taken in succession, before any grain is sown. No one states the average of that extensive flat country in Virginia, lying below the head of tide- water, at more than Jive or six bushels ; and in those fertile and beautiful valleys among the mountains, in which ignorant cultivators have not yet resided sufficiently long to have en- tirely exhausted the soil, the produce may not be less than twelve bushels the acre." These specimens of agricultural skill will not be adduced as proof of the favourite national position, that " we are the most enlightened people on the face of the globe ;" and the less so, as a lapse of eighteen years has not entirely weaned us from ancient habits ; for neither on the Maryland peninsula, nor in Eastern Virginia, is there any material alteration in their mode of culture, excepting what may have arisen from the fact that, having no more fresh land to exhaust, they are now obliged to recur to old field, and are, of course, annually suffering the new and increased penalties of former improvidence. On the western shore of Maryland, in the northern parts of Delaware, and in Pennsylvania, New-Jer- sey, and New- York, the state of things is better ; clover has been substituted for (what Mr. Strickland calls) rubbish pasture, and the root husbandry is encroaching on summer fallows ; which we regard as a decisive step towards a regular and judicious rotation of crops. After this brief statement of the past and present state of home agriculture, let us anticipate the fu- ture. We cannot believe that, favoured as we are with a temperate climate, a productive soil, an in- quiring, reflecting, and independent yeomanry, and civil institutions which favour and protect all the developments of industry and genius, we shall long PLANTS AND THEIR CULTURE. 77 remain behind the serfs of Tuscany, the tenants of England, or the peasants of Flanders. But, to rival these, we must follow their example ; we must mul- tiply the means of subsisting cattle ; because these will, in their turn, give manures, and manures will quicken and invigorate the soil for the production of -articles of the greatest value and the highest price. It is on this simple basis that we offer the following tables of rotation of crops, adapted to our own circumstances : Medium course in sandy soils : 1st year, potatoes dunged ; 2d, rye, with turnips after harvest consu- med on the fields ; 3d, oats and clover, or barley and clover ; 4th, clover ; 5th, wheat, with turnips after harvest consumed on the field ; and, 6th, pease, or lupines, or lentils. We have, by this course, eight crops in six years, and five of these ameliora- ting crops. Medium course in loamy soils : 1st year, pota- toes dunged ; 3d, wheat, with turnips as in the pre- ceding course ; 3d, Indian corn and pumpkins ; 4th, barley and clover ; 5th, clover ; 6th, wheat and tur- nips as before. In this course we have nine crops in six years, five of which are ameliorating crops.

THESE are wheat, rye, barley, Indian com, oats, buckwheat, pease, beans, turnips, potatoes, cabba- 78 AGRICULTURE. ges, clover, and chicory : but we shall take them in the order in which they stand in the proposed rota- tion of crops ; and, I. Of the potato. This plant is a native of America, and, like other valuable things, has had violent enemies and zealous friends. When first introduced into France, it was subjected to the imperfect methods of analysis of that day, and, being supposed to yield some delete- rious matter, was even proscribed by the govern- ment. But time, which rarely fails to do justice to the injured, has re-established the character of the potato there ; and with the increased reputation of being the " manna of the poor"* of standing as an article of food next to bread ,f and far before cab- bages, carrots, or turnips ;J and yielding, by the acre, a crop of greater profit and more nutritive matter than either wheat or barley. § Nor is this its whole praise ; for, besides its value as food, it is of all vegetables that which, from the number, shape, and size of its roots, forms the best prepara- tion for subsequent crops. || Of this valuable plant botanists count more than sixty varieties and twelve species, which, for agricultural purposes, may, how- ever, be reduced to three; the red, the white, and that called by the French the quarantaine, or forty days' potato. The last is the least prolific; but * Dictionnaire de 1'Industrie, art. Pomme de terre. f By the experiments of Vaugelin and Percy, 80 parts out of 100 of bread are nutritive ; of the potato, 25, or nearly one fourth. | " Six chilogrammes de pommes de terre equivaloient 50 chilogrammes de navet." — Vvart. Six kilograms [the kilo- gram is 2 Ibs. 3 oz. 5 dr. avoird.] of potatoes are equal to 50 kil- ogram* of carrots. § 200 bushels, a medium crop per acre of potatoes, are, at 3*. per bushel, equal to seventy five dollars ; and a medium crop of wheat, 15 bushels per acre, at even 16s. per bushel, is but 30 dollars ; difference per acre, $35. il Parmentier of the French Institute. PLANTS AND THEIR CULTURE. 79 may, notwithstanding, deserve the preference with cultivators near great cities, since, besides being the first in the market, they may be made to give a second crop. The other two are supposed to affect different kinds of soil ; the red preferring clay, and the white sand or loam. Of the former there is a variety more productive than any other of either species, and which is known, and, we think, de- graded, by the name of the hog potato. Of this variety, without any peculiar care, we have raised one hundred and eight bushels on one quarter of an acre. Two ways are employed to propagate the pota- to ; 1st, by sowing the seed ; and, 2d, by planting the root. By the former method we obtain new varieties or revive old ones ; but, as it requires three years to bring these to perfection, it follows that the other method, which continues the species you plant, and in the perfection in which you plant them, is alone resorted to for a crop. The product is small, or great, or enormous, according to the fer- tility of the soil and the labour bestowed upon its cultivation. We have never seen a larger product from the acre than four hundred bushels ; but there are records of high authority which give much larger crops ; and frbm which, in justice to our sub- ject, we offer the following extracts : " At Altingham, in England, a sandy soil gave 700 bushels per acre. At Kirklatham, a similar soil gave 580 bushels ; and a blach rich loam, 11G6 bushels."* We need hardly remark, that such immense pro- ducts were procured only by the most careful and well-timed cultivation, which we shall now proceed * See vol. xiii., p. 114, of the British Annual Register. Some persons have imagined that, by cutting the flowers of the potato, the crop may be increased, and analogy forms the opinion. The procreative powers of the plant are thus diverted from the ap- ple and concentrated in the bulb. 80 AGRICULTURE. to indicate under three different heads : 1st, the preparation of the soil ; 2d, the choice of plants and mode of planting ; and, lastly, the treatment of the growing crop. 1st. Of the preparation of the soil. Give your field intended for potatoes a good fall ploughing, and in ridges if the soil be clay. Leave it rough and open to the influences of the frost du- ring the winter, and as early in the spring as you discover in it the marks of vegetation, harrow and roll it. When the weeds show themselves a second time, carry out your manure, cover the fields with it, and plough it under. If the quantity of manure be insufficient to cover the whole surface, apply it to the furrows only ; and if, as may happen, it be even insufficient for this purpose, then furrow both ways, manure the angles of intersection, and set your po- tatoes in them. 2d. Of the choice of plants and mode of plant- ing. Some economists begin by paring the potato, and planting only the skins; others, less saving, cut the potatoes into slices, leaving a single eye to each slice ; and a third class, almost as provident as the other two, are careful to pick out the dwarfs, and reasonable enough to expect from them a pro- geny of giants. These practices cannot be too much censured or too soon abandoned, because directly opposed both by reason and experience. In other cases we take great pains, and sometimes incur great expense, to obtain the best seed. In the cul- tivation of wheat we reject all small, premature, worm-eaten, or otherwise imperfect grains ; in pre- paring for a crop of Indian -corn we select the best ears, and even strip from these the small or ill-sha- ped grains at the ends of the cob ; so also in plant- ing beets, carrots, parsnips., and turnips, the largest and finest are selected for seed. The reason of all this is obvious. Plants, like animals, are rendered PLANTS AND THEIR CULTURE. 81 most perfect by selecting the finest individuals of the species from which to breed. Away, then, with such miserable economy ; and, inetead of planting skins, or slices, or dwarfs, take for seed the best and largest potatoes, those having in them the most aliment for the young plants;* place them in your furrows ten or twelve inches apart, and cover them carefully with earth. 3d. Of the treatment of the growing crop. As soon as the potatoes begin to show themselves weeds will also appear ; a good harrowing will then save much future labour, and the injury it does the potato will be little or none. In a short time an- other weeding will become necessary; but your crop having now obtained some inches in height, you can no longer safely use the common harrow ; but, instead of this, the small one of triangular form, so made as to accommodate itself to the width of the intervals. This labour may be occasionally re- peated, if necessary, until the potatoes begin to flower, when the horse-hoe must be substituted for the harrow. The effects of this instrument (the horse-hoe) are to extirpate the weeds, to divide and loosen the soil, and to throw over the potatoes an additional covering of earth. The harvesting and preserving of potato crops are processes well known in this country. With regard to the latter, however, we would suggest whether stacking potatoes on the surface of the soil, and with a narrow base, is not a better mode than, burying them in the ground. Fifteen bushels will be enough for one stack, which must be well cov- ered with straw and earth, and trenched around its whole circumference, to carry off dissolving snows and rain-water. II. Of rye. * The interior of the potato forms the feaula, which subsists the young plants. 82 AGRICULTURE. This grain, though of the same family with wheat, is less valuable. A bushel of rye weighs less, and gives less flour, and of worse quality, than a bushel of wheat. Still there are circumstances which, as an object of culture, may give it the preference ; 1st, it grows well in soils where wheat cannot be raised ; 2d, it bears a much greater degree of cold than wheat ; 3d, it goes through all the phases of vegetation in a shorter period, and, of course, ex- hausts the soil less ;* 4th, if sown early in the fall, it gives a great deal of pasture, without'much even- tual injury to the crop; and, 5th, its produce, from an equal surface, is one sixth greater than that of wheat. These circumstances render it peculiarly valuable for poor soils and poor people, for mount- ains of great -elevation, and for high northern lati- tudes-t Its use, as food for horses, is known as well in this country as in Europe. The grain and straw, chopped and mixed, form the principal horsefood in Pennsylvania ; and in Germany, the postillions are often seen slicing a blapk and hard rye bread, called benpournikel, for their horses ; and the same practice prevails in Belgium and Holland. Its conversion into whiskey is a use less appro- ved by reason and patriotism. The species of this grain cultivated here are two, the black and the white ; for spring rye, though often mistaken for a species, is but a variety produced by time and culture, and restored again to its former character and habits by a similar process.f * We have seen a field bear rye several years in succession without manure, and the last crop was much the best. This fact is one of tliose which tend to discredit theory. t Without rye the northern part of Russia would be scarcely habitable. t Spring rye, sown in the fall, will give a tolerable crop ; winter rye, sown in the spring, a very bad one : which shows tkat the nature of the plant requires a slow rather than a quick vegetation. PLANTS AND THEIR CULTURE. 83 According to the course of crops detailed in our last chapter, potatoes, in a sandy soily precede rye. The ploughing, harrowing, and manuring given to that crop, will therefore make part of the prepara- tion necessary for this. After harvesting the pota- toes, crossplough the ground, and sow and harrow in the rye ; taking care, as in all other cases, that the seed be carefully selected and thorougly wash- ed in lime-water, as the means best calculated to prevent the ergot ; a disease to which it is most lia- ble, and which is supposed to be occasioned by too great humidity.* Rye is not exempt from the attacks of insects, but suffers less from them than either wheat or bar- ley. Whenever the straw of winter rye becomes yellow, shining, or flinty, and circulates no more juices, nature gives the signal for harvest, and no time should be lost in obeying it. " Cut tivo days loo soon rather than one day too late" was among the precepts of Cato ; which, if adopted here, would save much grain, terminate the harvest about the 10th of July, and give abundant time to turn down the stubble and sow the crop next in succession. III. Turnips. These are said to be natives of the seacoast of the north of Europe, where they are found growing spontaneously. There are eight species and many varieties ; but, as they have all the same character and uses, and require nearly the same treatment, we shall only speak of the white turnip and the yellow. Two methods of cultivation have been pursued, according to the plan either of turning them down as manure, or of consuming them on the field or in the stable by sheep or cattle. In the first case, the harrow is used instead of the plough ; and, even upon light, porous soil, is a pretty good substitute. The * See Tessier on the Diseases of Plants. 84 AGRICULTURE. seed is sown after the harrow, and too frequently left to its own protection. In the other case, the plough is first used, and after it the harrow ; a method much to be preferred, as the difference of crops will more than pay the difference of labour, the only advantage claimed by those who advocate and adopt the first method. Our own practice is to plough in the stubble, har- row the ground lightly, and sow the turnip-seed in the quantity of two pounds to the acre. This al- lows something for insects and something for waste. When the plants are generally above ground, give them a light covering of ashes, which, by quicken- ing the growth of the plants and leaching on their leaves at the same time, better protects them against the fly than any other means practicable on a large scale with which we are acquainted.* When the plants attain the height of four inches, we set the horse-hoe to work, running a furrow the whole length or breadth of the field, and returning with another at the distance of three feet from the for- mer, and so continuing the work till the whole is laid off into beds of that width. What we lose by this method is only the seed buried by the horse- hoe ; what we gain is the manure created by the young plants ploughed in between the beds, and the advantage of being able to weed and work those left standing for the crop. This part of the labour, which immediately follows the horse-hoeing, is ex- peditiously performed by two men travelling in the furrows, one on each side of a bed, and employing themselves in thinning and hand-hoeing the surplus plants. These operations of ploughing and weeding may be performed a second, and even a third time, with advantage. * On a small scale, water in which potatoes have been boiled is believed to be very useful in protecting cabbage, turnips, and other plants from the attacks of the fly. We are in a course of experiments which will determine how far this remedy may be relied on. PLANTS AND THEIR CULTURE. 85 If we determine to plough in the crop as manure, we should do it while the ground retains a tempera- ture favourable to the decomposition of the plants, and before the frost has diminished the volume or altered their juices. If, on the other hand, we de- cide on feeding off the crop on the ground, it is but necessary to turn in our sheep upon it, under such restrictions as will limit their range and prevent waste ; and, indeed, that nothing may be lost, hogs should be made to follow the sheep. If, however, feeding in the stables be thought more advisable (and it certainly better economizes both food and manure), the turnips should be drawn, topped, and stacked ; interposing between each layer of them one of coarse hay or other barn-rubbish, and cap- ping the whole with a few bundles of clean long straw. Though less nutritive than either potatoes, carrots, or cabbages, the turnip is found to be par- ticularly useful to stall-fed cattle, correcting, by its aqueous qualities, the heating effects of corn, oats, br rye meal. Our acquaintance with the yellow turnip (or ruta baga) is but beginning. Mr. Cobbett's experiments have, however, been very successful, and tend much to recommend the plant in preference to the white or common species. That, of the two, it is the more compact, the heavier, the more nutritious, the less apt to become stringy, and the more easily preserved, are facts not to be contested. In both France and England it is rising in reputation, and perhaps only wants time to get into general use here. To this article we will but add an extract from the work of M. D'Edelcrants (of Sweden) on the ruta baga. " Its root is milder and more saccharine than that of the other species, particularly when boiled. Its flesh is harder and more consistent ; which bet- ter enables it to withstand frosts, and to keep from one year to another. Its leaves extend horizon- H 86 AGRICULTURE. tally, and may be stripped off from time to time, as wanted for forage, without injuring the product of the root ; which, on good soil, gives to the acre, in Sweden, 350 quintals ; and, even on poor soil, a good crop. We sow half a pound of seed about the beginning or middle of May, which will give plants enough to fill an acre. Transplanting is performed about the last of June or first of July. To set out and water 5 or GOO feet in a day is the task of one man or of two women. One or two hoeings augment the product much. The harvest is made about the first of November, and the tur- nips are covered in ditches, or dry caves or cellars, for winter use." IV. Of Barley. It is probable that bread was first made from this grain. The Jewish scriptures speak only of barley loaves ; the gladiators among the Greeks were call- ed barley-eaters; and Columella says (like our In- dian corn and beans in the Southern states) that barley was the food of the slaves. Among the Ro- mans it was first employed as a food for man, and afterward for cattle.* The same qualities which recommended it then, have since diffused it more generally than any other grain ; it is found to be better adapted to different soils and climates ; less subject to the attacks of insects, and more easily preserved. In times of scarcity it is a good substitute for wheat, and at all times yields the beverage known under the name of beer, ale, or porter. It is, besides, a food on which cattle do well, and horses arrive at their greatest possible perfection. f The species of this grain most in request are two, Kordeum, Distichum (two-rowed barley) and Hor- * This use grew out of the belief of its nutritive and invigor- ating qualities. t See Buffon on the horse of Arabia. Vol. xxii., p. 195. PLANTS AND THEIR CULTURE. 87 deum Caeleste (naked barley). The former is pre- ferred in England, and, as we believe, in France. M. Parmentier ascribes to it all the good qualities of the other species, and much greater productiveness.* Of the latter species, the nations of the north who are most in the habit of using barley as the basis both of food and drink, speak highly. f But among us, who cultivate it only for the last purpose, this species has less credit, and is even considered the worst from a belief that, after being dried, it malts imperfectly or with difficulty. Though not so nice in relation to soil as either wheat or rye, still barley prefers a loose, warm, and moist, though not wet, soil, and even grows re- markably well in sand (where we have sowed it), in succession to turnips, either ploughed into the ground or consumed on the field. Other things being equal, the spring crops which are first sowed give the best and largest products. The moment, therefore, that your soil is sufficient- ly dry, begin ploughing, and at a depth not less than six inches, since the roots of barley enter the earth more deeply than those of any of the other cereal graminae. If the soil be well pulverized [as it ought to be after turnips], a second ploughing •would be a waste of time and money :J proceed, therefore, to sow your barley broadcast,^ and cov- * He states it to be double as much. f " Hordeum caeleste Norvegis gratissimum, quoniam cere- visiam generosam, praebeit."

J The Romans had two maxims on the subject of expense, which it would be wise in us to adopt : " Those profits are to be preferred which cost the least ;" and again, " Nothing is less -'profitable than very high cultivation." " Nihil minus expedire, * "quarn agram optime colere." $ Mr. Young's experiments show that there is something in the constitution or habits of this grain to which the drill or row husbandry is not accommodated. Even isolated grains weeded and hoed, did not do better than the same number in broad cast. 88 , AGRICULTURE. er it with a short-toothed harrow. The last opera- tion will be to sow and roll in your clover- seed, destined to become the next crop in succession. V. Of Clover. The Trifolium Agrarium of Linnaeus is found growing spontaneously in many places, as is suffi- ciently indicated by the names given to it ; as Dutch clover, Spanish clover, clover of Piedmont, clover of Normandy, &c., &c.* It is about two centuries since it first became an object of agricul- tural attention as forage, while its ameliorating ef- fects on the soil, produced by its peculiar system of roots and leaves, was a discovery of modern date. It is now generally sown with barley, or other spring grain of the culmiferous kind, and rarely by itself. The advantages proposed by this practice are three: 1st, the preparation given to the soil for the grain crop, which is exactly that best fitted for the clover : 2d, the protection given by the barley to the young clover against the combined effects of heat and dryness ; and, 3d, the improved condition in which it leaves the soil for subsequent culture. In this practice, however, a less quantity of barley must be sown than usual, because, without ventila- tion, the clover plants will perish. To this condi- tion two others must be added, which are indispen- sable to a good crop : 1st, that your seed be good ; and, 2d, that it be regularly and equally sown. The tests of good seed are, its comparative size and weight (the largest and heaviest being always the best), its plumpness, its yellow or purple colour, its glossy skin, and, lastly, its cleanness or separ- ation from other seeds and from dirt. The human hand was, no doubt, the first ma- chine employed for sowing seeds. The difficulty, * A seed of Holland clover, of the same volume with one of Normandy clover, weighs one seventh more. See Gilbert on Artificial Meadows. PLANTS AND THEIR CULTURE. 89 however, of scattering them equally over every part of the field, soon attracted notice, and engaged me- chanics in devising something which should better answer that purpose. China was the first to produce anything at all commensurate with this object ; and it was not till the seventeenth century that this, or some similar invention, was introduced into Europe by Lucateo, a Spaniard, who, meeting no encour- agement at home, transmitted his real or pretended discovery to London. Here, as has been conjec- tured, it served as a model for the sowing-machines of Tull ; and from 1750 to 1770, the mania on this subject was at its height; but from that period to the present it has been gradually subsiding, and the hand is now generally restored to its original func- tions. The quantity of seed to be given to the acre should, in a great degree, depend on the soil ; if this be rich, ten or twelve pounds are sufficient ; and if poor, double that quantity will not be too much. The practice of mixing the seeds of timo- thy and rye grass, &c., with that of clover, is a bad one, because these grasses neither rise nor ripen at the same time. Another practice, equally bad, is that of sowing clover seed on winter grain before the earth has acquired a temperature favourable to vegetation, and when there cannot be a doubt but that two thirds of the seed will perish. By the time your barley or other covering crop is harvested, your clover will be sufficiently estab- lished to live alone ; and, if not pastured* to brave the ensuing winter, and during the next summer to repay your labour by two abundant crops of grass or hay. The period in the growth of clover at which it *• If the crowns of young clover roots be nibbled or otherwise wounded, the roots die. Sheep and horses (both of which bite closely) should, therefore, be particularly excluded from clover, unless intended for pasturage only. H 2 90 AGRICULTURE. is most profitably cut and used, presents a question much discussed and variously answered ; because depending on extraneous and local circumstances (such as the state and proximity of markets, &c.), which cannot fail to vary the results in the hands of different persons, and even of the same person at different times and at different places. There are, however, some general remarks which belong to the case, and which ought not to be omitted in even this brief view of the subject. 1st. Clover cut before it flowers abounds in water, has in it but. little nutritive matter, and is even apt to produce indigestion in the cattle fed upon it.* 2d. The stems of clover cut after seeding are hard and woody, arid no longer hold the leaf: and, 3d. All plants, when permitted to seed, exhaust the soil ; and to this rule clover is not an exception. From premises furnished by these facts, we would conclude that the short period between the flower- ing and seeding of clover is that in which its use would be most advantageous, whether regarded as & forage or as an ameliorating crop. When seed is the principal object of culture, we cannot do better than adopt the practice in Hol- land, where the first crop is cut before it flowers, and the second is reserved for seed. The largeness of the stems, the number of the leaves, and the aqueous quantity of both, render it a difficult business to make clover grass into hay ; and the difficulty is not a little increased by the brittleness or disposition of the drying grass to fall into pieces during the process of handling. To meet this case, two supplementary means have been employed, which enable you to house or stack clo- ver in a much greener or less dry state than would otherwise be safe. The one is to scatter over each * This effect of clover (which we call hoving) is prevented in Alsace by watering the cattle before giving theiii clover, be- cause a certain quantity of water prevents fermentation. PLANTS AND THEIR CULTURE. 91 cartload, while stowing away for keeping, two or three quarts of sea-salt : the other, to interpose be- tween two layers of clover one of clean straw. By the first method, the whole mass is made accept- able to cattle ; by the second, the quantum of nu- tritive forage is increased ; and by both methods the clover is effectually prevented from heating* The next step in our system is to plough in the clover stubble as a preparation for the succeeding crop. VI. Of Wheat. This grain, so useful to man, because forming so large a portion of his subsistence, is happily found to adapt itself to a great variety of soils and cli- mates. It grows vigorously in clay, in loam, in calcareous earth, and even in sand, when aided by manures, or in succession to pease, vetches, clo- ver, &c. To the north it is found in the frozen regions of Siberia ; and in the south, under the burning sun of Africa, it yields, according to the declaration of Pliny, more than one hundred fold.f In ancient Rome, its use, as a food for man, soon superseded that of barley and rye ; and in modern Europe it is denominated corn, by way of eminence. Of this invaluable grain there are four species, -•distinctly marked and generally acknowledged, viz., many-headed wheat,{ Polish wheat, spelts, and * The more modern, and, we think, far better way of making •clover hay, is to put it into small cocks as soon as it has become dried or wilted in the swaths ; and to leave it so for thirty or forty hours, when it will be found sufficiently dried, on being opened and spread to the sun an hour or two, to take to the barn or stack. In this way it makes the most and best fodder, and is cured with the least labour. — J. B. f " Tritico nihil est fertilius : utpote cum e modio, si sit ap- tum solum, quale in Byzacio Africae campo, centum quinquageni modii redden tur." — XVIII. L. Nat. Hist. Pliny. Nothing is more productive than wheat ; for a bushel of this grain, sown on a soil adapted to it, as that of the plain of Byzantium, in Africa, will yield a hundred and fifty fold. $ This is the Triticum Compositum of botaniwa, called wheat 92 AGRICULTURE. common wheat. We shall speak only of the third and fourth species, because with the others we have little practical acquaintance ; and, 1st. Of Spelts. This species and its principal va- riety (Triticum Monoicum) is much cultivated in Germany and Switzerland. Deprived of its husk, the grain is smaller than that of common wheat, but yields a flour of finer quality, and better fitted for the purposes of pastry.* Two other circumstances recommend it; it withstands the attack of insects, and will grow in poorer soil and with less prepara- tory labour than the fourth species. 2d. Common wheat has many varieties, some of which are bearded, and others bald ; some oval, and others round or square ; some yellow or red, and others white ; some soft, and others flinty ; acci- dents arising from culture and climate, and not, as we believe, the result of an organization uniformly and essentially different. With regard to the culture of this plant, we shall confine ourselves to the following points : the prep- aration of the soil, the choice and preparation of the seed, and the time and different modes of sow- ing or planting it. 1st. Of the preparation of the soil. Products of much value to man can only be ob- tained by corresponding degrees of labour. The sugar-cane, rice, and wheat, are more valuable than oats, buckwheat, or turnips, and require more la- bour and expense in their cultivation. Indeed, un- der the old system of fallows, the degree of both bestowed upon a wheat crop was enormous. Two years and five or six ploughings were sometimes given to this preparatory culture ; but, on the new plan of a rotation of crops, the necessity for this of plenty, miraculous wheat, (fee., yielding largely, but, on manu- facture, giving much bran and bad flour. * The bread of Frankfort, Nuremberg, &c., so much boast- ed in Germany, is made from spelts. PLANTS AND THEIR CULTURE. 93 is in a great degree obviated, and two ploughings of a clover lay are in general amply sufficient. Still this takes for granted that these ploughings are well performed ; that no clods are to be seen ; and that the field presents an unbroken surface of mellow and finely-pulverized earth. 2. Of the choice and preparation of seed. Seed should be taken from some fine crop of the preceding year* which shall have ripened thorough- ly and been well preserved. This, after passing two or three times through the fanning mill, should be carefully washed in clean water, and again in water in which a quantity of fresh lime has been slackened ; or, if lime cannot be had, in which clean and recent wood ashes have been leached. This washing, as we have already suggested, should never be omitted: because, besides detecting the shrunk or shrivelled grains, and many seeds of other plants which will float on the surface of the water, it entirely removes the dust of smut, rusty &c., and thus prevents their propagation, f Our * A great variety of experiments show that wheat preserves its germinating faculties under circumstances apparently very unfavourable, and that it may even be sown to advantage when several years old, after a slight degree of malting in the sheaf or the stack, and after having been subjected to a high degree of artificial heat. We mention this fact, however, not to invite to a selection of seed-grain of either of these descriptions, but to assure the farmer that, where better cannot be had, he may employ even such, without apprehending a total loss of his time and labour. t Smut, charbon, and rust in grain, were, according to the old philosophy, attributed to storms, or s'ome other particular state of the atmosphere ; but Messrs. Tillet, Tessier, B. Prevpt, and Decandolle, have shown, that the two former of these diseases are produced by an intestinal parasite, of the uredo or mushroom family, the progress of which is much promoted by humidity and shade. Analogy favours the opinion, that rust owes its ori- gin to the same cause. The remedy for all is the same ; wash your seed-grain thoroughly in lime water, roll it in plaster of Paris, and sow it in the fall, before the cold and wet weather begins, or in the spring after it has ended. 94 AGRICULTURE. next step in this process is to roll the seed in pul- verized gypsum. 3d. Of the time of sowing wheat. On this head there is a diversity both in practice and opinion. Some prefer early, others late sow- ing : some sow in the full, others in the wane of the moon, &c. Theory is certainly on the side of early sowing ; since it gives time for the roots of the grain to es- tablish themselves before winter; and experience proves that grain early sown throws up more lat- eral stems than that which is sown late. Of lunar influences we know very little, except- ing that they extend to the waves of the ocean ; which probably first gave rise to the opinion held by M. Toaldo and other philosophers, that the at- mosphere, which is only another and more fluid ocean, and which has much to do with the health and diseases of animals and vegetables, is also sub- ject to these influences. But the calculations of M. de Place prove that the effect of lunar influ- ence on the atmosphere does not make a difference of one line and a half on the barometer, and that it is wholly insufficient to account for those great agitations of the atmosphere which have been sup- posed most to affect vegetation. 4th. Of the different modes of sowing wheat. These are two, the one executed with the hand, the other with a sowing machine, of which we have already spoken. The latter has been advocated on the ground of economy, employing less seed, and distributing what it does employ more equally. Nor will it be denied that, when wheat is very high and labour very cheap, there may be a saving in the use of this machine ; but in all other circumstances the comparison is in favour of the other method, as it requires less time and fewer labourers, and as the waste and irregularity imputed to it are, in hands practised and steady, reduced to little or nothing. PLANTS AND THEIR CULTURE. 95 A third method of propagating wheat, viz., by transplanting the suckers at regular distances from the seed-bed into another prepared to receive them, has been practised on a small scale, and is found to yield abundantly ; but it is so embarrassed with ex- pense as to render it entirely unfit for general use. Of the produce of wheat very different accounts have been given. To the extraordinary fertility of Byzantium, already mentioned, Pliny adds that in Leontium, in Sicily, its produce was one hundred for one ; yet Cicero, who had been quaestor of that island, asserts that the produce of Sicily was but ten or twelve for one.* To conciliate these high and opposite authorities, M. Yvart has supposed that the product mentioned by Cicero was an aver- age one of the whole island ; and that that report- ed by Pliny was the result of one or more trans- planting experiments ; an opinion rendered probable from the fact that the parent stems and their off- spring had been sent to Rome by the procurator of Augustus. Some calculators have supposed, and on data not easily refuted, that the maximum produce of this grain over the whole face of the globe, and in a series of any ten given years, will not exceed six bushels reaped for one bushel sown.f VII. Of Pease. The pea is a native of the southern parts of Eu- rope, and is found growing spontaneously in the western parts of our own continent. The family is a large one, containing several species ; but of these the field-pea alone comes within the scope of our present purpose. Of this there are two varie- ties, denominated, from their colour, the gray and * Orat. contra Verrera. t The reader will remember that, on our plan, turnips follow wheat as they do rye, and without any difference in cultivation. See article 3d of this chapter. To repeat what we have said there would be useless. 96 AGRICULTURE. the green; both productive, and, when separated from the skin that surrounds them, a food of excel- lent quality for man, wholesome, nutritive, and pleasant ; and for cattle, whether in a dry or green state, much to be recommended. Sheep, cows, and horses are particularly fond of them ; and hogs are more promptly and economically fattened on a mix- ture of pea and barley meal, in a state of acetous fermentation, than with any other food. The structure of the roots would indicate that pease are an exhausting crop ; and it is on this evi- dence that in Europe they are admitted only in long, or six years' rotations ; but if we examine the leaves, in regard to both number and form, we shall probably find reason to modify this opinion, and to allow that, by stifling weeds, by checking evapora- tion, and eventually by their own fall, they ameli- orate the soil, and render it more favourable to sub- sequent crops. Following turnips in the rotation we are now dis- cussing, the preparatory labour for a pea crop is not great. One, or, at most, two ploughings, will be sufficient. Sowing, as a general rule, ought to fol- low ploughing without loss of time ; and care should be taken that the seed be not laid too deeply. The two methods, row and broadcast sowing, may be indifferently pursued. By the former the seed is economized, the product increased, and the soil bet- ter tilled; but not, as some have supposed, with such decided advantages as to outweigh the saving in time and labour, of the latter. The length and feebleness of the stems of pease, and the little tendrils they throw out for support, indicate the advantage of mixing with them other plants of more erect growth, which may prevent the pease from falling and lodging. For this purpose rye, oats, and beans have been selected, and with great advantage. This crop is employed either in a dry or in a PLANTS AND THEIR CULTURE. 97 green state ; between which every farmer will se- lect according to circumstances. If the market for pease be brisk and high, he will harvest, thresh, and sell the grain ; if, on the other hand, pease be low and pork high, the moment the pods fill he will turn in his hogs upon them, and with the following ad- vantages : 1st, the hogs will feed and fatten them- selves, without any additional interposition of his labour ; 2d, no part of their manure will be lost ; 3d, the remains of the crop, refused by the hogs, will be given back to the soil ; and, 4th, the rooting of these animals, which in other cases is an injury, will in this be a benefit. VIII. Of Indian Corn. This is a native of South America, and was in- troduced into Europe in the 16th century ; where it is known by the names of wheat of Turkey, Indian wheat, Spanish wheat, &c.* Its productiveness and other good qualities have brought it into general use ; for it is now found in every part of the globe where its cultivation is not forbidden by the cold- ness of the climate. With proper culture, it grows well in a great variety of soils; but prefers old and rich pasture-grounds, artificial meadows, warm loarns, and moist vegetable mould. There are many varieties of this grain, denomi- nated from its colour, number of rows, and differ- ent periods of ripening. The white and the yellow, of eight and twelve rows, are the varieties general- ly preferred. Corn, from its bulk, its prolific character, and sys- tem of roots, must necessarily be a great feeder, and draw much of its supplies from the earth; whence arises the rule that it ought not immediate- * This is the Zea of the botanists. In what does this differ from the zea or semen of the ancients ? The favourite dish of the Romans was alica ; and " Alica fit e zea, quam semen ap- pellavimus"— Alica is made of a grain called semen.— Plin. 18 LjSat.Hist. I 98 AGRICULTURE. ly to follow or to precede any other cereal crop ; and that it should not be found oftener than once in six years in the same field. The seed should be taken from the finest ears of the last year's crop, and from those growing on stems which have had the largest number of ears. After steeping it twenty-four hours in a strong so- lution of nitre, it should be planted.* There is some difference of practice, without any great difference of result, in the modes of planting. Furrows are sometimes made at the distance of three or four feet from each other, and in one direc- tion only, and in these the seed is placed fourteen or sixteen inches apart. At other times the field is furrowed both ways, and the seed dropped and cov- ered at the points of intersection ; while, again, two rows of beans or potatoes, or mangel wurzel, are sometimes interposed between as many rows of corn. This last practice is most conformable to theory; but the other methods generally prevail, and pumpkins, beans, or turnips form the under crops. Whatever method be adopted, the time of planting is that at which the earth first acquires the warmth necessary to vegetation, and which is sufficiently indicated by her spontaneous productions. If we plant earlier, the seed is apt to rot ; if later, the ripening of the crop is hazarded. No crop, while growing, requires more attention than corn, and none better repays the labour be- stowed upon it. The objects of this are two : to extirpate weeds, and to keep the earth loose and open to the influences of the atmosphere. As soon, therefore, as weeds begin to show themselves, the surface of the field must be well harrowed. Plas- tering is the next operation, and may, at the dis- * See in Judge Peters's Notices to Young Farmers, the effect of this solution on com crops. PLANTS AND THEIR CULTURE. 99 tance of a few days, be repeated with advantage. The weeds will now reappear, when the triangular harrow, accommodated to the width of the inter- vals, must be employed. This, drawn by a single horse, will do its work expeditiously and well. The plough called the cultivator, with a double mould- board, follows the harrow,* and is itself followed by the hand-hoe, which alone can perform well the last and great operation of hilling^ the corn. The first effect of this is to enable the grain to form new- joints near the surface of the earth, whence will issue lateral roots, fitted to receive an additional quantity of aliment necessary or proper for the plant.]: Care rrtust, however, be taken to flatten these little mounds of earth, so as to make them better recipients of water. Corn is sometimes cultivated with a view only to the forage it may yield ; in which case it is gener- ally sown broadcast, at the rate of ten bushels to the acre, and cut green, while its saccharine quali- ties most abound. We are told by Bosc, that in the volcanic soil of Vicenteri, in Italy, corn managed in this way gives four crops in the year. As a dry forage, it is a great resource in warm climates, where natural meadows are rare, and artificial near- ly unknown. In the eastern parts of Virginia, it furnishes the principal stock of horse fodder, and in our northern latitudes is a useful supplement to clover, timothy, and red-top hay. The produce of corn is much affected by weath- * The implement now termed cultivator, or horse-hoe, is of recent introduction among us. We have it of various patterns, and it is coming into extensive use in the culture of hoed or drilled crops, in place of the plough.— J. B. f Hilling corn is becoming an exploded practice, as being rather prejudicial to the crop than otherwise.— J. B. $ Bonnet was the first to make this observation ; but, if the reader wishes to see a full illustration of it, we refer him to the Memoir of M. Varennes de Fenillis, who has proved that the crop is increased M3th merely by hilling. 100 AGRICULTURE. er. If this be hot and dry, the leaves, stems, and ears are all diminutive ; if wet, the leaves and sterns are abundant, but the ears deficient and often dis- eased ; if both wet and cold, no ears are produced; while, on the other hand, if it be moist and warm, more particularly when the grain is flowering, the crop will be excellent. To produce this combina- tion is not within the reach of human industry. All, therefore, that agricultural foresight can effect, is to interpose a few days between the planting of different parts of the crop, so as to multiply the chances of favourable weather. IX. Of Beans. Of these there are several species, which, to oc- cupiers of clay soils, are of the utmost importance, because in them beans thrive best, while, at the same time, they greatly ameliorate and fit them for wheat and oat crops. The species most recom- mended are the Heligoland,* or small horsebean of England, and the white bean.f The former is vigorous, hardy, and productive, and an excellent food for cattle ; the latter is more delicate and nu- tritive, and much employed as a food for man.J If beans are made to commence a course of crops, as they may very properly do, they ought to receive the dung of the year; which, as in the case of potatoes, should be spread over the surface of the field, and ploughed in without loss of time. The moment the spring frosts are over, the planting should take place, in rows or in hills, as described in the last article for corn; and throughout the * The Heligoland, and other beans of the vicia family, are not found to do well with us. They grow and blossom, but do not fruit well.— J. B. t This, as well as the China and other beans of the genus Phareola, are profitably grown on sandy as well as on clay soils. — J.

In the former, the early production of its blossoms (which always precede the leaves)! greatly expose it to frosts, the slightest of which are sufficient to destroy it ; and in the latter, from causes not sufficiently explored, '"the fruit falls," as we are informed by Bosc, "be- * " The profits of this culture in the south of France arruning the mulberry is in the spring, because it is ,hen you can best distinguish the blossom buds from )thers.

The RASPBERRY (Rubus). — Of this plant there are wo species, subjects of garden culture : the Ideus, >ropagated for its fruit ; the Odoralus, for its per- ume and its rose-coloured flowers. It is only of ,he varieties of the former that we shall now speak. These are, 1st, the Wood Raspberry, giving a fruit mall and sweet, increasing in size, but diminishing n flavour, under cultivation. 2d, the large common Raspberry (both red and white), giving good fruit, and a great deal of it, if favourably situated and well managed. In rich and shaded soils it loses much of its flavour; and in those freely manured with stable dung, becomes disagreeable to the taste. 3d, the Large Red and the Large White Antwerp, de- cidedly superior to the preceding sorts, but more troublesome, as they are not productive but when laid down and protected from the winter frosts. And, 4th. the Cane Stock, regarded on the whole as the fittest for the main crop. This plant is a native of cold and mountainous regions, and, of course, succeeds best when placed on the north sides of hills, or in borders a little *• Hort. Trans., vol. hi., p. 63.

A soil loose and moist (not wet), and oc* casionally and lightly manured with the surface mould of old pasture land, is most favourable to it. Like other plants which perpetuate themselves by suckers, as the Annana, the Jasmin, the Bread Fruit, &c., the raspberry soon becomes infertile; and hence the rule for setting out new plantations every seventh or eighth year. This is done by seeds and cuttings, but better and more generally by suck- ers, taken up in the fall or in the spring, and set out in well-laboured trenches four feet asunder, and at the distance in these of two and a half feet apart. If placed nearer together, they crowd and injure each other ; and if farther removed, they lose the advantage of the shade they would otherwise mu- tually furnish. The raspberry, when left to itself, remains long barren, or productive only in leaves and wood ; but, so soon as it acquires a sufficient number of lateral branches, its fertility commences. To hasten this effect, therefore, is the great desideratum in the cul- ture of the plant ; and the knife is accordingly em- ployed freely and annually, in removing the old wood, and in shortening the young to one third of its length. Of the retained and shortened shoots, not more than five should be left to a bush ;* and if they be either of the Antwerp races, they should be carefully covered with earth on the approach of winter, as otherwise the effect of the frost will much impair, if it does not entirely destroy, their fertility for the ensuing season. We need scarcely add, that, though hardy, the raspberry, to do well, must be kept from weeds. * Loudon. J. C. Kecht ( Versuch der Weinbau) produces ber- ries at Berlin much larger than are known elsewhere, by train- ing a single stem to the height of 8 or 10 feet, and vigorously re- moving all suckers. This is directly opposed to the theory of shortening the stems for the purpose of producing side-shoots ; without which, it has been generally thought that the plant could not be made productive. FRUIT GARDEN. 277 The STRAWBERRY (Fragaria). — Of this there are several species, the principal of which are the Pine, the Single-leaf or Monophy lla, and the Chili, natives of South America ; the Carolina, the Scarlet or Vir- ginian, and the Wood, natives of North America; and the Hautboy, and Alpine or Prolific, natives of Europe. Of these, the Alpine and the wood are best propagated from seeds, as in this way they never fail to reproduce themselves, and give fruit as soon, and of a finer quality, than the offsets. The other species are more readily multiplied by run- ners ; which, as they take root at every joint, and grow the more vigorously the more they are cut, necessarily furnish a great abundance of plants. When seeds are used, we must be careful to em- ploy fresh and well-ripened fruit, mashed in the hand, and mixed with a little mellow earth, and sown in rows three feet apart. When, on the other hand, runners are employed, they must be taken off near the ground, divided into sets, planted in rows as in the other case, and occasionally lightly shaded and watered, until they give evidence of having taken root, which they rarely fail to do very prompt- ly. In both processes, the ground must be kept loose and clean, and moderately manured with com- post dung. With regard either to general or special rules in this case, we cannot do better than to make the read- er acquainted with the method of Mr. Keans, of Islesworth, an English fruit-gardener, who has cul- tivated the strawberry with uncommon success. "In preparing the ground," says he, "if new and stiff, trench it ; but if the subsoil be of an inferior kind, simply dig it, and place the dung at the bot- tom : if, again, the soil be good to the full depth, bring the bottom spit to the top, and the top spit to the bottom, and place the dung between the two. The month of March is the best time for planting either seedlings or runners, and remember to make your A A 278 GARDENING. plantations of these, and never from old plants. Sow in beds of three or four rows, with alleys be- tween the beds to walk and work in. When the planting is finished, keep the bed free from weeds, and permit no crops between the rows. When the runners begin to show themselves, cut them away at least three times in the season ; and at each cut- ting dig the ground between the rows ; and as of- ten, cover the surface with a sprinkling of clean straw,* for the purpose, principally, of preventing evaporation. One of these cuttings must be done a short time before the fruit ripens, and will have a powerful effect in strengthening the root ; and, at the second digging, work into the rows a little half- rotted dung." To these remarks, which apply to all the varieties alike, Mr. Keans subjoins a few specific notices as follows : " 1. For the Pine strawberry the best soil is a light loam, though no other strawberry will bear a strong loam better than this. This is the sort from which it is most difficult to obtain a good crop. Particular care must be taken that they are planted in open ground; for in small gardens they grow strong, but seldom bear fruit, in consequence of being shaded by standard trees, and, under walnut-trees in in particular, they run altogether to leaf. In planting pines I keep the beds two feet apart, and put the plants eighteen inches from each other in the rows, leaving three feet alleys between the beds. The first year of the pine is the best ; the second gives a good crop, but the third gives less. " 2. The Scarlet must be treated like the Pine, excepting that the rows may be a little nearer to- gether, and the alleys between them a little less. " 3. The Hautboy thrives best in a light soil well supplied with dung ; for excess of manure does not * It is from this practice that the plant derives its name. FRUIT GARDEN. 279 drive it into leaf like the pine. In other respects, the culture is the same as for the pine. There are, however, many different sorts of Hautboys : one has the male and female organs in the same blos- som, and bears freely ; but the sort I prefer is the one which contains the male organs in one blossom and the female in another. The fruit of this is of the finest colour, and of far superior flavour. Care must be taken that there are not too many male plants in the bed ; for, as they bear no fruit, they make more runners than the females. One male to ten fe- males is the proper proportion for an abundant crop. " 4. The Wood strawberry is best raised from seed fresh gathered, sowing it immediately in a bed of rich earth. When of proper size, I transfer the plants to other beds, where they continue till the next March. They are then planted out in beds and rows, and at the distances before described. And, " 5. The Alpine or Prolific must always be raised from the seed, sown in a bed of rich earth. When of proper size (which will be in July or August), the plants are put out in rows, at the back of hedges or of walls, in a rich, moist soil ; the rows two feet apart, and the plants twelve inches from each other. My Alpines this year, and thus managed, are bear- ing most abundantly ; and so much so, that, in gath- ering them, there is not room for the women to set their feet without destroying many. In quickness of bearing the Alpines are before all other sorts, as they give their fruit within a single year ; whereas the others do not bear under two years." In gathering the fruit, employ only dry weather. Berries taken early in the morning and late in the evening keep the best, but those picked at midday have the most perfume. Pinch off the calyx and one quarter of an inch of the peduncle with the berry. The WALNUT (Juglans regia). — This tree is sup- 280 GARDENING. posed to be a native of Persia, and of the southern side of Mount Caucasus, and yields a nut which holds a considerable place among the dessert fruits, and which has been recommended, as far back as the time of Pliny, as a safe and powerful vermi- fuge.* Its varieties are the Oval, the Large French,! the Tender, and the Thick-shelled. To obtain these, Millar and Forsyth recommend sowing the nuts in a nursery, keeping them clean, and leaving their maturity to time, without any in- terposition of art to hasten their productiveness. But Knight and others have succeeded so well by inarching and budding, that these methods may be considered as having nearly superseded the older and slower modes of propagation. In employing the former (inarching), your young plants, growing in pots, are raised to some branch of an old bearing tree, and grafted by approach. A union takes place in the summer ; and in the fall you detach the scion from the parent stem. In the other case, the pro- cess is equally sure and less troublesome. Many minute buds, almost concealed in the bark, will be found near the base of the annual shoots. These must be taken in preference to those which are fuller and more prominent, and inserted near the summit of the last year's wood, and, of course, near the base of the annual shoots. "Thus managed," says Knight. " they will be found to succeed with nearly as much certainty as those of other fruit- trees, provided the buds be in a more mature state than those of the stock into which they are set." The walnut-tree grows well in many different soils, but does best in a deep, sandy loam, resting on a dry subsoil. It is often employed as a screen for other and more delicate fruit-trees, in which case it is arranged on the northern and western side * The Spaniards grate the nut into their tarts, &c., probably with a view to its supposed medicinal quality. f Before 1562 it was called the Gaul or French nut.

The CHESTNUT (Fagus castanea) is a native of Sar- dis, and, it is said, was first brought to Europe by Ti- berius Caesar. Be this fact as it may, another, of which we are. better assured, is, that the tree has^ been long naturalized in Italy and Spain, and that' in these countries it contributes an important article to the food of man. Like the walnut, it was long propagated by sow- ing the nut; but the shorter process of grafting (as already detailed under the preceding article) may be advantageously substituted for this. The exper- iments of the late Sir J. Banks and of Mr. Knight demonstrate that " the Spanish chestnut succeeds readily, when grafted in almost any of the usual ways ; and that, when the grafts are taken from bearing branches, the young trees blossom the suc- ceeding year."* The soil most proper for the chestnut is a sandy loam, on a dry subsoil. With regard to situation, it does well in northern and western borders ; but, as its shade is unfriendly to any vegetable growing under it, the better method is to give it a square by itself. The FILBERT (Corylusavellana). — This is the com- mon hazelnut improved by cultivation. Its princi- pal varieties are, the White, the Red, the Barcelona, the Cosford, and the Long Cob, all of which are prop- agated alike by suckers, by layers, and by seeds. When the last of these modes is employed, sow the nuts in October or November, and keep the plants in the nursery till they are two years old; after which, set them out, and manure and dress them occasionally. But the better method of propagating them is that by suckers. These are taken up in * Hort. Trans., vol. i., p. 61.

Williamson is, however, of opinion, that the severity of this discipline de- feats itself, and is, in fact, the reason why the plants give no fruit three years out of five. Instead, there- fore, of a rigid adherence to the Maidstone practice, he recommends " that the trees be left in a great degree to their natural growth and shape." In some parts of England, the filbert forms an ob- ject of very profitable culture, giving, per acre, on an average produce of five years, five hundred pounds' weight of nuts. The maturity of the fruit is indicated by the brown colour of the nut and the husk, and the readi- ness with which these separate. Braddick's method of preserving the fruit, by putting it up in airtight casks, is no doubt the best. The filbert is neither often nor seriously attacked by insects. The eggs of the curculio kukans are sometimes deposited in the germen, where, when matured, they subsist upon the kernel. The only cure for this is to de- stroy the nuts which are so attacked, and with them the larvae, before they attain the fly state. 14 DAY USE RETURN TO DESK FROM WHICH BORROWEI LOAN DEPT.
