" M373375 EDITOE'S PREFACE THE present volume is based upon a series of articles on "Farm Crops and Cropping," which has appeared within the last few years in the " Journal of Agri- culture, and Transactions of the Highland and Agri- cultural Society." Much of the matter therein given has been here availed of, but the whole has been re- modelled, and a large amount of new material added, in order to bring the volume within the scope of the Miscellany, of which it forms a part, and up to the most recent date of practical experience. From the interest which the articles above alluded to excited at the period of their publication, it is hoped that in their new, amended, and greatly-extended form, they will serve — in the much wider circle this Miscellany addresses, and aims at reaching — that practically use- ful and suggestive purpose the author, in their pre- paration, had in view, and which he has here en- deavoured more fully and completely to realize. In succeeding Parts of this important department of Farming Literature — the Culture of its Crops — the subjects of Oats, Barley, Beans, Pease, Turnips, Man- gold Wurzel, Cabbage, Artificial and Natural Grasses, Clover, &c., &c., will be consecutively taken up, and fully discussed and illustrated. THE CULTURE OF FARM CROPS. DIVISION I. THE CEEEALS OR GRAIN CROPS. PART I.— WHEAT. CHAPTER FIRST. INTRODUCTORY. ORIGIN OF WHEAT. 1. OF all the grain crops of the farm, wheat is the most important, as being that chiefly on which man is dependent as a food. In tracing the history of this invaluable plant, we find that its origin is lost in the remotest antiquity. In Holy Writ, and in the writings of classical authors, we meet with abundant evidence of its wide-spread utility as a food for man. Believing it to have been created spe- cially for him, and starting into existence as complete in itself as the acorn which grows upon the oak, it serves little practical purpose to devote time to proving, or at- tempting to prove, that the wheat plant has been developed from an inferior grass. This development theory is no new thing. -The Greeks, centuries ago, endeavouring to trace the origin of the wheat plant, believed that they could trace its origin to the wheat- like grasses which then, as now, were met with on the shores of the Mediterranean, and which are known as the A 2 CULTURE OF FARM CROPS. " ^Egilops ; " and it is somewhat singular that, in recent times, the speculations as to the origin of wheat take pre- cisely this direction of those of ancient times. Of modern savans who have paid attention to this department of agri- cultural science, M. Esprit Fabre, of Agde, in France, has devoted considerable time to its investigation. Of the grasses known as the ^Egilops, to which, like the ancients, M. Fabre traces the origin of the wheat plant, there are three species, the ^Egilops triundalis, ^Egilops Ovata, and ^E. triarestata. To these three a fourth is sometimes added, and which is called ^E. triticoides, from its possessing some of the triticoid characteristics of wheat. We say this i? sometimes added to the list of species of ^Egilop grasses. but as M. Fabre believes that he has shown that this fourth is derived from the ^Egilops ovata, the classes may be taken as three in number only. But although M. Fabre believes that the result of his experiments with plants of the species ^Egilops ovata was a plant to which the name of -^Eg. triticoides was given, and from the seeds of which he ultimately, by sowing them in succession for twelve generations, obtained a " true wheat plant ; " other author- ities take exception to this decision, and maintain that the plant ^Egilops triticoides was not a distinct species, or a new plant, but that it was merely a hybrid plant, which possibly resulted by a union between a plant of the com- mon wheat, and a grass of the species /Egilops. This in- genious idea was first broached by M. Godron, and was followed up by a series of most elaborate investigations which ultimately established the fact that the ^Igilops triti- coides was a hybrid, and that it was easy to understand how its cultivation resulted in bringing it to a true wheat ; for, as M. Godron says, hybrids, " when fertile, tend to return, after a certain number of generations, to one of the two types which has given them birth." Space prevents us from going farther into this question of the origin of the wheat plant — we can only refer the reader desirous to pur- sue the matter, to the Journal of Agriculture (No. 82, p. 139), where a resurn6 of the points involved will be met with, ORIGIN OF WHEAT. 3 merely pointing out here, that as yet no evidence, in any way to be relied upon, has been presented in favour of the view- that the wheat plant has been developed from a grass. The difficulties in the way of the development theory are great indeed, — so great, that it takes a much more credulous spirit to enable us to accept conjectures of so vague a kind as true, than to believe that as for wise purposes, God created man, so he created at once the wheat which was to form then, as it does now, so important a part of his daily food. Not to name here the scientific difficulties surrounding the development theory, the common sense ones are sufficiently startling to give us pause before we accept it as correct. Thus, to glance at one only of the many considerations, — who amongst the early races of mankind saw with prophetic glance the food-bearing wheat in the lowly grass which he trod upon, and which waved in the wind but as a worth- less weed to others, and by whose incessant care was its cul- tivation carried out, till at last this care was rewarded by seeing the grass converted into grain 1 If it took a modern savan so much long and patient painstaking care to bring about a result which, after all, to put it in the mildest way, was very doubtful, is it possible to conceive that, in the remote periods of man's history, some one, nay many, were found to exercise a like care 1 It is difficult to conceive of this j much less difficult surely is it to believe, if we can accept of the fact that as the acorn has been produced from the oak from the earliest stages of created things, so in like manner has the wheat plant borne upon its stem the life-supporting grain. Practice in farming will be none the less wisely followed out if the farmer, in place of endeavouring to prove that it is by the exercise of man's wisdom and his guiding care that we owe the wheat, he believes in patient faith, and trust that it " is one of those natural blessings " which a good and kind Provi- dence bestowed upon him. CULTURE OF FARM CROPS. CHAPTER SECOND. BOTANICAL PECULIARITIES, AND VARIETIES OP WHEAT SEED STEEPING. 2. Wheat belongs to the order of plants monocotyledonous — that is, having one seed-lobe, and having endogenous stems — that is, stems which are increased from within, and are hollow and nearly parallel, or of equal diameter through- out, not increased by layers or rings (exogenous). The leaves are long and tapering, and have parallel veins not reticulated like the leaves of exogenous plants. This class of plants is termed Glumoles, from the glumes which take the place of the calyx or outer envelope of ordinary flowers. The order in this class of plants to which wheat belongs is called Graminacece, and the genus Triticum ; so called because the seed is to be ground or triturated (from, tritum) before being fit for use as food. The species of the family of triticoid plants are exceedingly numerous, and various writers have adopted various classifications. M. Yilmorin classifies them under seven heads, and the arrangement is adopted in Professor Wilson's excellent work, " Our Farm Crops." The principal classes are T. sativum and T. tur- gidum. (1.) Triticum sativum, or common wheat, this being divided into two classes, the " bearded " and the " smooth," the bearded having twenty-seven, and the smooth seven varieties ; to one of these belong our common winter and spring wheat, these again being distinguished by one colour, as red and white. Of the white varieties, the following are named by Professor Wilson — Brodies, Chiddham, Dwarf Cluster, Essex, Fenton, Hopetoun, Hun- ter's, Pearl, Spring, Talavera, Uxbridge, Velvet-eared or Rough-chaffed. Of the red varieties — Barwell, Browick, Bristol, Glover's, Heckling's Prolific, Keningland, Lammas, Piper's Thickset, Spalding's, Yelvet or Woolly-eared, Bearded. The second class of cultivated wheat is Triticum turgidum; this class is, however, not in general cultivation, THE KIND AND QUALITY OF THE SEED. 5 being confined to districts where soil is cold and stony. The yield of this class of wheats is generally high in quan- tity, but in quality is low and coarse ; but the straw not being, as in the other class of wheat, perfectly hollow, but, partially filled up with a pith-like spongy substance, is strong, and capable of standing well under adverse circum- stances, and is useful for thatching purposes. The varieties of turgid wheats named by Professor Wilson are Eivet common, Eivet bone, Egyptian or Mummy wheat. 3. Winter and Spring Wheat. — The class of Triticum sativum has been in agricultural nomenclature, and is still by some divided into two — summer or spring wheat, Triti- cum sativum; and winter wheat, Triticum hibernum. This distinction is, however, now discarded, as it is admitted that by change of circumstances their characteristics may be changed also, so that by repeatedly sowing winter wheat in the spring, we can alter its ripening capacities so as to make it spring wheat, and vice versa. " Spring and autumn wheat," says Professor Buckman, " are not specifically dis- tinct ; both the one and the other may be sown in any month of the year, a subject upon which I have experi- mented again and again, and thus given a spring wheat the habit of a winter one, and the reverse." 4. The kind or variety and the quality of the Seed. — The whole subject is one invested with the deepest interest to the agriculturist desirous to obtain the maximum of pro- duce with the minimum of outlay. In an exceedingly interesting and able paper by Mr. W. Wallace Fyfe, in a re- cent number of the Journal of the Bath and West of Eng- land Society, on " Farm Seeds and Seeding," there are some very suggestive remarks on this very point, of which we give here a very brief resume, referring the reader to the article itself for fuller details. After referring to the un- fortunately too general ignorance on the subject prevailing amongst farmers, Mr. Fyfe draws attention to the evidence which so many fields of wheat show as to the carelessness with which the seeds have been selected, bringing about a general discrepancy of result ; and in place of having the 6 CULTURE OF FARM CROPS. produce of one particular kind — a condition, as Mr. Fjfe remarks, " essential to good cropping, and uniform ripening and growth " — the seeds are chosen, or rather, to speak correctly, taken indiscriminately without choice, so inter- mixed in variety, that the " stalks of some overtop the others, and many of the grains drop dead-ripe out of the ears before the rest are ready for cutting down." The farmer, he justly remarks, cannot control the seasons, but by choosing his seed- wheat with care he may modify them to a very considerable extent in his favour. With the deeper cultivation of our soils, secured by improved and powerful mechanism, it is probable that if better results are not attained in a degree easily marked by common ob- servation, still we may predicate with safety, that a condi- tion of matters will be brought about more favourable than hitherto to the cultivation of the finer and more productive grains. Seeing that this will be one of the good results of an improved system of culture, the importance, as Mr. Fyfe remarks, of being able to discriminate between one kind of grain and another, is obvious enough. Taking the number of wheats cultivated generally at the present time at fifty, " nevertheless minute marks appertaining to particular grains," must be registered and borne in mind by experts in examining them. " The mere size, shape, or colour afford no distinctive tests. One grain, however, has a central ridge which is characteristic, another is pointed to both ends, a third to the right, and a fourth to the wrong or life-bud extremity only ; a fifth variety is marked by the prominency of these life-buds, a sixth possesses near the pointed end a peculiar wrinkle, whilst a seventh and an eighth may be known by having this wrinkle more or less pronounced. These peculiarly distinctive marks are nevertheless only to be taken as such in the several classes of wheat to which they are specially appropriate, since accident or sport in vegetating may render them in- terchangeable in others also." Although the distinctive marks characterising different varieties of wheat are thus liable to change, still on the whole, " means exist of suffi- DIFFERENT VARIETIES OF SEED-WHEATS. 7 ciently describing every variety of grains in cultivation," to attain which most desirable end Mr. Fyfe suggests the use of the microscope, while prudently pointing out that " trial and experience will alone determine their suitable- ness for any given soil, climate, or situation, for any estab- lished system of cultivation, or any new and experimental method of growth ; " he says, and says truly, that " in the first instance it is surely of some moment to know what the seeds really are, and to make a study of their charac- teristics." 5. As regards the different varieties of Seed-ivheats little need here be given further than to glance at the names and leading peculiarities of those generally cultivated in this country, following here the classification and selection adopted in the paper from which we have quoted. Of the white wheats thirty varieties are named. These are Archer's prolific and Australian wheat — this last has created some attention amongst growers of late, in the hope that, main- taining its characteristics of early growth, " the period of our harvest might be altogether accelerated." This in some trials of it has been realised, Mr. Fyfe mentioning an in- stance where it ripened a month before the usual time ; in other trials the hope has, however, not been realised. In some, indeed, of which we ourselves have been cognisant, the per-centage of ruined or non-germinated seeds was alarmingly large ; and it does not follow that because a wheat may possess characteristics favourable to early growth and prolific powers in one climate, it will show these in another. The cultivation of Australian wheat has been undertaken largely by the Continental Agricultural Societies, specially that of the Belgium Central Society. Seed has been widely distributed, and every means taken to arrive at a just estimate of its value. The following paper, from the pen of M. Vogelhanger in one of the foreign Journals, will be of service here. " The diversity of opinions given on the subject of wheat from Australia, and the request which you made me with regard to my personal information, require me to give 8 CULTURE OF FAEM CROPS. you, upon this kind of corn, some short notices, resuming my observations of ten years ago, when I cultivated this cereal. I will state first, that under this denomination there are several kinds of grain in commerce which differ much in their quality, in the quantity of their produce as to the place where they come from, and especially as to the degree of their acclimatization. I commenced by cul- tivating the wheat from Australia, as procured to me by Mr. Vauden Bosch, a learned agriculturist, in the island of South Beveland. This corn gave me at first a fine and good produce, but I abandoned it soon, because its crop dim- inished yearly, and it degenerated, so to say. Then comes in turn the wheat that our Society, I believe, had ordered to come direct from Australia intermediately by the ship- owner Duclos, at Ostend. The latter had the goodness to send me, in October 1857, two hectolitres, which I sowed as soon as possible in a good piece of ground, very fertile. This corn gave me, in 1858, a produce of 60-J hectolitres the hectare, a wonderful produce in the countries here, ex- citing the incredulity of several of my compeers, but never- theless true and authenticate, of which I have given a de- scription in the Landbow Gourant, No. 51, of the year 1858. The wheat had very short ears, from 5 to 7 cen- timetres, with husks of a dark brown colour, so that the grains were almost white, very heavy (83 kilogrammes by hectolitres), with a very fine film, and giving a flour which makes the finest bread. The grains are very much ser- rated, and are joined one to another, which was the cause of the great crop ; the straw, shorter than that of other kinds of wheat, gives the advantage of never being laid. Since 1858, when I cultivated this kind with advantage, and in competition with the Talavera, an English, red- strawed wheat, and the " ruwarige " of Gueldre, and al- though I have reasons for always being pleased with it, I must admit that its produce has diminished much, vary- ing from 40 to 30 hectolitres by hectare. I endeavour myself to prevent or to diminish the degeneration by sowing each year, upon a piece of ground apart, the grains DIFFERENT VARIETIES OF SEED-WHEATS. 9 having the finest ears ; these I made to be put in sheaves (at least with scissors) until I had a hectolitre of grains, a very useful and easy operation, since the colour and form of this kind of wheat makes it different from all others. Mr. Van Alsteyn, member of council for our Society, praises his Australian wheat as much, — seed got also by the in- tervention of the Society, and for which he has been first at Brussels. The grain seems really to have precious qualities, but differs much from mine, as much in ears as in grain and straw. Perhaps it comes from another part of Australia ; some one told me that mine came from the neighbourhood of Sydney. Although it has been so, up to this year I have always sowed my ground with this kind of wheat, but I have never observed wastes occur by cold before snow and winter were over. Sown by means of the corn-drill of Hornsby, in October of the last year, at 22 centimetres apart, it grew very well, passed the first part of the winter and the frost at the season without hindrance, so that, after the frost, I did not perceive any waste. But some days following it was cold again (without snow), which was the cause of the greatest dis- aster. The greater part of the plants gave way in March, as they were very incapable of resisting longer. Con- fident in the vegetative faculties which this kind possesses to the greatest degree, some cultivators allowed the crop to take its chance ; others decided to destroy the remain- ing part, or to replace it by barley in spring, or, later, by oats or pease. It happened thus that the greatest part of sown ground with Australian wheat was ploughed and rendered capable of producing other grains. As for myself, I resolved to sacrifice everything, but having alone a third of my land I put in pease, recalling the experiments that I had made last year with different kinds of wheat, bar- ley, rye, &c., and particularly with the wheat from Halett, planted grain by grain in the ground, according to the pre- scription indicated, experiments of which I have given a description in the Landbow Courant, or Vylad of this year ; the fields sown with Australian wheat, although the 10 CULTURE OF FARM CROPS. plants have been frozen certainly nine-tenths, present a most luxurious aspect ; the strongest stems push to the number of from 20 to 30 each plant ; the large leaves, of a dark green colour, and showing in appearance great strength, hinder one from seeing the interstices of the rows, and promise a produce which, although not being so abun- dant as is usual, will be, however, very remunerative for the expense and care which the cultivation of this wheat re- quires." 6. Eesuming our list of white wheats, we note first the improved Berkshire, possessing some of the characteristics of Archer's prolific, already noticed. Brittany or Breedar. Brodie's, much esteemed in the Lowlands of Scotland for the beauty of its sample and the earliness of its ripening. Brown-strawed Scotch Cheedh am orChedharn, also known as Pearl white. Chevalier ; under this name several varieties are included — the ten-rowed variety yields a heavy pro- duce, the grain being thin-skinned, straw of medium length. Cluster wheat, first introduced under the name of Dudney; there are two varieties, the 'dwarf and ' tall.' Dantzig wheats are referred to by Mr. Fyfe as having been found ' to be not at all adapted to our climate ; ' and, further, the experience obtained by growing them here is corrobo- rative of the opinion held by 'almost all our advanced practical men,' that the practice is not a good one which proceeds upon the assumption or theory that the develop- ment of the grain is favoured by a change of seed from ' a later to a more forward climate.' In introducing these wheats, brown, red, and white, the hope was entertained that the ' habit of late maturity ' acquired by them in cold countries would be found capable of change by their trans- ference to our climate. ' Duck's-bill yellow ' wheat was introduced into Jersey by Colonel Le Coteur from Kiel, on the Baltic; the young plants are very hardy, the ears ' singularly compact,' the grain plump, and of a light yel- low colour, yet easily shaken out, and yielding an inferior flour. ' Essex white ' is held in high estimation by millers from the fine quality of flour it yields ; the straw is about DIFFERENT VARIETIES OF SEED WHEATS. 11 4 feet 6 inches in length, not apt to lodge, and yielding fine handsome ears, with a transparent thin-skinned grain. ' Eltham,' known also as ' Whitworth,' in the county of Durham and the northern wheat districts of England, where it is in great repute for spring sowing, arid for its early ripening. * Eclipse,' although a favourite in the south of England, was not successfully introduced into Scotland, alteration in the quality of the sample being the result of the change from a superior to an inferior climate. ' Een- ton's,' ' Hunter's,' ' Hopetoun,' and ' Mungoswells,' are all allied Scotch wheats, enjoying a high reputation in certain districts. Of the straw of these, Eenton's is the shortest, being 4 feet 1 inch ; Hunter's 4 feet 5 inches ; Mun- goswells 4 feet 5 inches ; and Hopetoun, the longest, 4 feet 7 inches. Of these, Mungoswells is chiefly used in East Lothian, the place of its introduction, the introducer being the well-known authority in cereals, Mr. Patrick Sheriff. ' Essex rough chaff,' although much grown, is ' subject to blight in unfavourable summers.' It is esteemed by the London millers from yielding ' a find white flour with little bran.' ' Grace's ' wheat, in its general character- istics, resembles Hunter's wheat ; much grown in certain districts of England ; it is ' considered too delicate for the climate of Scotland.' ' Kent white ' is both hardy and prolific ; it is extensively grown in England. ' The Eed- chaffed wheat ' is in high favour with- many farmers, the quality being fine, giving a weight of from 62 to 64 Ibs. per bushel. ' Red-strawed white ' is suitable for both win- ter and spring sowing, an early ripener, and gives an aver- age yield of from 63 to 68 Ibs. per bushel. ' Talavera,' the prime favourite, says Mr. Eyfe, ' for quality in the wheat crop;' it can be sown at a later period of the season than any of the common wheats. ' Taunton Dean,' a favourite in Suffolk, where it ' yields heavy crops of a mel- low sulphur-coloured elongated grain, tapering towards both ends, inserted in long and compact ears, with straw of moderate height and stiffness.' Another wheat greatly cultivated in the south of England, with a variety of names, 12 CULTURE OF FARM CROPS. is ' Trump, or Trumpeter's wheat.' Under the name ot ' Hardcastle,' a stiff-strawed variety, it is grown extensively, and considered the ' best and most fruitful of the whites.' The grain is thin-skinned, and averages from 63 to 66 Ibs. per bushel. ' Uxbridge ' yields wheat the great favourite of the London millers; 'it is everywhere prolific, and its grain, though somewhat small and short, is plump and white, forming an elegant sample. Uxbridge is well worthy the attention of the cultivators of fine wheat.' ' Whittington,' Wellington, or Eleys wheat was introduced from Switzerland by Mr. Whittington of Eipley, who re-- commended it for ' thin and inferior soils ; ' it is not adapted for rich and heavy soils, the straw being in the; e apt to lodge on it ; is long and soft. It is in some dis- tricts considered valuable for spring sowing, as it ripens early. 6. Of the red ivheats, Mr. Fyfe names twenty varieties : ' blood red ' is the variety commonly cultivated in the west of England, although ' it is by no means a model pro- duct of the red-wheat.' ' Erowicks ' has the reputation of being the best ; it is highly thought of by millers, who habitually use it for mixing with white wheat flour. The ' bearded or April red,' see fig. 3, enjoys a good reputation as a profitable crop ; indeed, bearded wheats are gradually rising in estimation, and they seem especially adapted to fickle and stormy climates. The ' beard ' has many use- ful qualities ; it prevents the grain from being knocked up in windy weather, acting like a spring or a ' buffer ' when the ears are forcibly driven in contact by the wind ; the elasticity of the beard is also useful in preventing the ears lying too closely together when in the sheaf, so that a free circulation of the air between them is maintained. Of the red wheats, ' nursery ' is held in high estimation by mill- ers, ' who value this wheat alone equally with our best white, since its seeds, which are small, long, and slender, with a bright shining skin, yield flour of the best quality. It is distinguished by having an ear with white chaff and straw of the medium length, and its popularity is no mar- DIFFERENT VARIETIES OF SEED WHEATS. 13 I 14 CULTURE OF FARM CROPS. 4.

The ' red lammas ' is the most esteemed of the red wheats in Scotland. The c kessingland,' a prolific red wheat, is thought by Mr. Fyfe to be the progenitor of the ' giant pedigree ' and ' nursery prodigy of the day.' For notices of the ' characteristics of other red wheats, as Spalding's prolific, Piper's thickset, Kent red, Hallett's pedigree nur- sery (see fig. 1), golden drop, giant, Essex, or golden red, Dunstable cluster red, conservative, Biddle's imperial, and Britannia, we refer the reader to Mr. Eyfe's paper.

The subject of the ' change of seed wheat ' has been much discussed of late ; this, like other ' vexed questions ' of agriculture, is marked by the contrariety of opinions brought forward by those who ought to be authorities. Generally, however, a ' change of seed ' is considered a de- sirable point to be attended to ; so much, indeed, is this view held by some, that they change their seed every year. The subject, says a writer in the ' Mark Lane Express,' is one which deserves ' full discussion.' He says : — " The points I wish more particularly to have cleared up are — 1st, the nature of the change, i. e., the kind of wheat ; 2d, the best change, and the best kinds of wheat for different soils ; 3d, the best change of climate, i. e., from a warm to a cold district, vice versa; 4th, the best change from different soils, i. e., from clay to chalk, or peat to loam or sandy, or to gravelly soils, or vice versa in each case respectively, or whatever changes may have been found desirable from soil to soil in any case. " A friend of the writer occupies a farm in Bedfordshire, and another in Lincolnshire marshes. His custom relative to his seed-corn is to change it from one farm to the other annually ; and he assures me he does it with great benefit 16 CULTURE OF FARM CROPS. in both cases, one of the proofs being, and that under re- peated trials, and upon both farms, he finds that in com- petition with other kinds of seed- wheat the importations in both cases ripened earlier by about ten days than those varieties grown for comparison. The Bedfordshire farm is a retentive clay, the marsh farm a thin loam, upon a silty or sea-sand subsoil. This is a fact worth knowing, and I trust my readers will give us many such, and also many other useful facts tending to elucidate this subject. " At the risk of being thought presumptuous I will offer my advice. Every farmer should regulate his course in these matters according to his best judgment and experi- ence. The varieties of wheat are very numerous ; he best knows what sorts have proved well under his culture; these he should adhere to rather tenaciously, but with occasional deviations, or by introductions of new sorts, if well recommended. He should always change his seed ; but he must be very careful that the seed is clean, and from a favourable district or climate ; this he soon ascer- tains, either by his own experience, or on the information of others. The great thing is, that he takes care to do it. Depend upon it, that if this change be judiciously effected, it will amply repay the little additional cost. My opinion inclines most to a change from either a chalky, gravelly, or peaty soil, to a good loam, or a clayey loam, or heavy clay, and vice versa; also a change from a warm or a dry climate or soil, to a cold or a wet climate or soil; and I should demur as to taking seed-corn from a cold or wet climate at all. I should also recommend sowing the best and heaviest grain, and not to drill in more than from six to nine pecks per acre, always taking into consideration the fertility of the soil and the order of seeding." 8. In connection with the raining of seed for the direct purposes of the farm, it is worth noticing here the ad- vantages which would accrue from the habit of a close observation of each field of wheat when near its period of ripening, with a view to select and save those ears which, from their size or the beauty of their sample, SELECTION OF SEED-WHEAT. 17 afford a marked contrast to the general average of ear in the same field. We have never yet walked carefully along the side of a field of wheat — and it is generally towards the outer lines, where the grain is exposed to light and air, that attention should first be paid — but we have seen ears which in value far surpassed others by which they were surrounded. There can be no doubt that if this careful supervision of our wheat-fields were given each season, not only would the best samples of any given or recognised variety, but samples of new varieties would be obtained. The marking of these would be a work doubtless of some trouble, and so also would be their gathering and the plac- ing of them in proper packets or bags ; but in one sense it may be said that business is a trouble, and yet no man thinks of neglecting his business because it is so. In gathering the selected ears a careful description of their peculiarities should be drawn out and kept for after-refer- ence, along with one or more of the ears. The ears selected for the purpose of raising produce in the following season, should be carefully cleaned and laid aside till the period of sowing. A plot of land should then be selected and laid out in subdivisions, and one or more of these allotted to the sowing of one particular variety. It will add much io the, value of the experiments, and greatly, we may here remark, to the pleasure of the experimenter, if he will keep an accurate record of the " behaviour," as engineers say, of the produce of each plot — the dates of sowing, of brairding, blooming, and ripening. While writing these remarks on a subject in which we are specially interested, and in the carrying out of experiments in connection with which we have derived much pleasure, we have come across a few remarks in a contemporary journal bearing so closely upon the subject, that we shall do our readers good service in making them here. The article is one on the propagation of hardy and prolific varieties of our cereals ; and in point- ing out how this may best be done, the writer has the following : — " But there are limits to the beneficial in- fluences of such improvements j and the ascertained produce 18 CULTURE OF FARM CROPS. of the present year's crop will, in most cases, force more strongly upon the attention of authorities that it is very important to select varieties which are comparatively highly productive even in adverse seasons. Some misapprehension exists as to the influence of improvements. A dry soil is necessarily of a higher temperature than one which is wet, and consequently is better adapted for the growth of the more tender kinds of the cultivated plants, more particu- larly of wheat. Still the temperature of the atmosphere and the amount of sunshine are very important conditions for the healthy growth of all the corn crops ; and too much stress should not be put upon the counteracting influences of drainage, deep stirring, and high cultivation, in adapting land for the cultivation of the more tender kinds of cereals. The grower of corn requires to study to obtain a superiority of produce so as to acquire a high average return during the period of occupancy; and as inclement seasons occur at longer or shorter intervals, it is the more necessary to grow hardy and productive varieties, as well as to render the soil suitable for the healthy growth of those kinds selected. The combining of these conditions will usually secure success." "We shall hereafter point out how the experiments connected with the raising of good samples or of new varieties should be carried out; but we have here to add to our notes one from the article above allud- ed to, having reference to the produce of the experimen- tal plots. It should be carefully seen that the character of the produce agrees with the one which was originally recorded, "as it is quite probable that a new kind has been produced accidentally — what vegetable physiologists term ' sporting.' " It is right also here to remind the experi- menter of what the writer of the above article has so judiciously drawn attention to — namely, that all the ex- periments will not be alike or at all successful ; but * if success crowns one selection out of ten, the raiser of a new and superior variety will generally reap some pecuniary benefit, while his name will be recorded as the propagator of a hardy and productive variety.' We heartily coincide THE CHOICE AND QUALITY OF SEED. 19 with the writer of the article in his opinion that agricul- tural societies have made a mistake in confining their attention exclusively to the encouragement of superior breeds of animals, and in neglecting the encouragement of the raising of new varieties of the vegetable produce of the farm, on the successful and productive raising of which, the existence of the animals so much depends. 9. As regards the choice of Seed and its quality, it certainly is remarkable how little care is in general exer- cised. It seems indeed to be but stating a truism when we say that the labour of cultivation is altogether lost if we use seed which cannot be fruitful, or that which is diseased. The axiom in farming should never be lost sight of, ' as the seed sow the crop,' and the further axiom, that we lose all our labour in preparing land if we commit to it seed which will bear the minimum of produce, or what is worse, bear none at all. Although what we have said as to the importance of having good seed if we require good crops is evidently founded upon correct principles, and is indeed the creed of the enlightened portion of the agri- cultural community, nevertheless, that a contrary opinion is held by some will not be wondered at by those who know how uncertain a thing agricultural practice is, and how far removed from the position of a fixed science agri- culture is. But it is, however, difficult to believe that one writing to an agricultural paper should give advice to others, based upon such a principle as this, ' if you desire to reap a first-rate article you must sow a second-rate article,' Evidence is then offered in support of what is called the ' truth ' of this extraordinary opinion, but into which we do not care to go. The writer has been taken in hand, and, to make a bad pun, ably handled by the well-known writer, " The Old Norfolk Farmer," of whose reply we have only space to give the following : — " But to be consistent," the correspondent " should carry his principle out a I'outrance, as the French would say. Thus in selecting his breeding cattle and sheep he must reverse the practice of great men, and choose the most ill-shaped, 20 CULTURE OF FARM CROPS. raw-boned, half-starved animals he can find. What is sauce for a goose is sauce for a gander, and if the principle is good in the case of wheat, it must be also in that of all other grain and seed, and of animals as well." No more need be said ; if this new view is right all our scientific teaching is wrong, and nothing is left us but to begin again and upon a new tack. That the quality of grain or seed has a very marked influence upon the produce of the crop there can be no doubt, for, as one of our highest authorities says, a diseased or weak parent cannot give a sound or strong progeny. The following remarks, from the pen of a Continental Authority on this point, will be useful here. " Seeds which have not acquired their full develop- ment, and all the qualities of the species they represent, generally yield but weak products. There may be ex- ceptions, but the facts which I shall cite appear very conclusive. " Seeds that are incomplete for want of maturity cannot produce complete types. Do we not find similar results in animals that are too young or too old1? A bull, a cow, a horse, whose members are incompletely formed, cannot impart what it does not possess. A decrepit animal, too — can it impart what it has lost? I think not. Dogs of a breed whose tails have been cut for many generations are born without tails. I have had pigs in a similar condition. Cows without horns produce similar calves. " In gardens, we obtain plants deprived of certain organs ; others which have them in abundance, and which end in producing varieties. Thus eschalottes which have been too long sown near onions, yield no longer any seed, and become useless. For the same reason, some varieties of potatoes have ceased flowering, because we take them up for a long time before the period of flowering. Seed taken from flax and hemp of great height, but not having acquired their full maturity, yield very small products ; and if we continue to harvest it before it is fully ripe, the plants will go on diminishing in vigour and height to such an extent, THE CHOICE AND QUALITY OF SEED. 21 that after some years our flax and hemp seeds will be transformed into dwarf species. " Colza, of the large kind, which we harvest before its complete maturity, in order to avoid losing the seed, di- minish in height after a few years. If afterwards we allow these degenerated species to attain maturity, we shall restore their size by degrees, until they reach the point from which they had declined. We may therefore diminish or increase in size the breeds of animals and species of plants, by em- ploying for reproduction, individuals that have acquired all these qualities, and are capable of transmitting them ; or else, by taking others imperfect, and unable to impart what they do not possess. "Twelve or fifteen years ago, trefoil sown in one of my fields, after presenting in autumn the finest appearance, disappeared in the spring. The leaves shrivelled up, the stalks did not rise, the major part of the plants dried, and were attacked with a species of decay. I attributed this disease at first to the state of the soils, then to the tem- perature ; in short, to three or four other causes more or less likely ; but the bad quality of the seed did not occur to my mind. " Some years later I harvested, before its full maturity, some rye that T had sown for forage, and which, not being able to consume it in proper time, was kept to make bands. It was cut while yet green ; but the grain, in appearance ripe, had probably not acquired that degree of perfection indispensable for reproducing its species. I sowed this rye in order to obtain forage in the spring. It came up well, and exhibited a good vegetation at first ; then the foliage became yellow and wasted, and the soil became so denuded, that I found it necessary to plough it up to re- place it with another crop. Many causes were alleged for it, but the true one remained still unknown. Last year, however, in a field of three hectares, which had borne a fine crop of beetroot, I sowed in April barley and clover. In two-thirds of the field I sowed clover-seed of middling quality that had been taken from very vigorous plants, but 22 CULTURE OF FARM CROPS. the heads had not ripened in a uniform manner. In the other part, I sowed seed perfectly ripe, and of the best quality. " At the time of harvest, after having cleared the field of cereal crops, the cloveu was fine throughout, and the field presented a uniform aspect. As the clover was high enough to be mown, it was cut for forage in October, and it main- tained its fine appearance until December. Towards that time many of the stools of the clover in that part where we had sown the bad seed dried up ; then others ; and at last, in the spring, there remained of them only a few tufts, here and there ; the rest had either died out or were so poor that we could no longer reckon upon them : they seemed to have been pierced by insects. Those stools, proceeding probably from the refuse seeds, still subsisted, and yielded a middling crop, being few in number ; the second cutting was rather better, but still it was meagre. In that part in which the good seed was sown I retained a good crop of forage, cut green, and the second cutting was very fine, very thick, and seemed of a different species. " In view of this fact, I recollected my first pasture of trefoil and rye, and of some sowings of wheat, which had the same result. "When farmers come to me for seed of my large beetroots, in order to have them of the same size on their farms, I say to them, ' Dung well and plough deep, and you will have them as fine with any other seed.' In the meanwhile, I have often been assured by them that they have sown my seed, and others less ripe, and the beet- root proceeding from them appeared not to be of the same species. " I will not go so far as to say that everything depends upon the seed ; for a good seed committed to a bad soil, or one badly prepared, will assuredly yield a bad crop ; whilst seed of an ordinary quality will sometimes succeed in a good soil. But I am satisfied, from observations which I have had the opportunity of making during an extended practice, that the choice of seed is very important, and that PREPARATION OF SEED FOR SOWING. 23 we cannot make too great sacrifices to obtain seeds well harvested, and that have arrived at their full maturity." 10. Preparation of the Seed for Sowing, — "Wheat un- fortunately is subjected to a disease arising from the attacks of parasitic fungi, which produces what is called ' smut.' In a future part of this series we shall go fully into the subject of diseases of our farm crops ; meanwhile, we give a few remarks upon the means in practical use for getting rid of the smut in wheat, which, if allowed to remain in the seed, greatly deteriorates the produce in quality and quantity. When we consider the fact that when the spores of the fungi, which produce smut, and those which produce ' bunt,' another disease which is even more dreaded than the smut, enter the plants which they attack by means of the spongioles of the roots, we see at once the necessity that exists for securing clean seed ; and further, when we know that the spore-dust which adheres to the grains is of an oily or greasy nature, we also see that the substance which we employ to cleanse the seed should be of an alkaline nature. Lime and urine • are the alkaline substances used for dressing wheat-seed for the prevention of smut and bunt, and sometimes sulphate of copper : it is questionable, how- ever, whether the use of the latter is advisable, inasmuch as it is likely to have a bad effect upon the germinating powers of the seed. The following, upon the methods em- ployed in using lime, urine, and vitriol dressing, from the pen of a student at the Royal Agricultural College, and extracted from a recent publication, is so apposite' to the point under consideration, that we make no apology for giving it here : — " A sack of wheat is placed on the floor in the form of a conical heap, flattened and concave on the top ; a lump or two of lime are then thrown into a bucket, and a gallon or six quarts of boiling or cold water added. A rapid ebullition ensues, during which time it should be well stirred, to insure a perfect slacking of the lime. In this state it is thrown into the concave top of the conical heap of wheat, and well mixed with a shovel till all the grains 24 CULTURE OF FARM CROPS. appear to have come in contact with the lime, and then left for a few hours, when it will be dry enough for drill- ing. This method of dressing is generally done over-night, and left in a neat conical heap (which the superstitious old farmer used to cross with the ' besom,' the handle of which was thrust into the cross) till the morning. This eccentric method was adopted with the belief that it kept the witch from executing her evil designs. When urine is resorted to for pickling, it should be kept in a tub for a few days prior to using it, as fresh urine voided from healthy sub- jects possesses an acid reaction instead of an alkaline, which it only acquires by keeping a short time. The urea, a nitrogenous compound in urine, takes up four equivalents of water, and becomes converted into two equivalents of car- bonate of ammonia — ' smelling salts ' of the chemist — giving the whole an alkaline reaction : a condition which is necessary to insure the removal of the smut-balls. . . " Where urine is used, the wheat may be dipped into it; or the former may be poured over the latter in sufficient quantity to well moisten the whole. " Another agent which is commonly used in pickling wheat is sulphate of copper (blue vitriol), in the following manner : — 4 Ib. of the vitriol should be dissolved in about two gallons of boiling water, and when fully dissolved, placed in a large tub — an old hogshead cut through the middle answers the purpose very well — and add about 20 gallons of cold water. Procure a wicker basket of suitable shape to go into the tub, large and strong enough to hold a bushel and a half of wheat. Place the basket in the liquid, and gently pour into it the wheat. By adopting this precaution the light arid imperfect grains, chaff, or small seed will float at the top, and may be skimmed off the sur- face. Having proceeded thus far, lift the basket, and allow it to drain over the tub; empty the same, and proceed with the next lot. This method will be found very convenient as well as effectual; but the most effec- tual remedy consists in selecting a good, clean, and even sample for seed, from a climate suitable for a change, when POISONS USED FOR STEEPING WHEAT. 25 each kind of dressing will be found to answer the pur- pose." 11. Arsenic and other poisonous substances are also used for steeping wheat, and are more or less effectual. Of late a considerable discussion has taken place with reference to the dangerous effects of these poisonous steeps for wheat ; the two following paragraphs comprehend nearly all that can be said on both sides. The first is from the pen of Mr. Hewitt Davis, a well-known agricultural authority, — second from a correspondent of the Agricultural Journal. " The use of poisoned seed-wheat," says Mr. Davis, " is so general, and is attended with so much danger to human life, and is so destructive of game, that I trust I may be permitted to question the supposed advantages that give rise to it. My own practice as a farmer for many years was to use copperas, arsenic, and other mineral poisons in preparing my wheat for seed, as a means of preventing smut, burnt ears, and other diseases from the growth of parasites on the corn, coming under the name of { uredo.' I was told that these powerful mineral poisons destroyed the sporidia of disease without injuring the sound seed. But seeing the sad consequences in the game-field and rookeries, and one year losing nearly all my young turkeys from their getting into a field newly sown with wheat, I was led to ask how it was possible that seed corn could be benefited, and the seed of parasites be destroyed by the use of poisons shown by the growth of the corn to be so in- nocuous to vegetable life ; and I came to the conclusion that the benefit from dressing of seed corn was due to the cleans- ing that it got in the process, and not to any effect of the poison upon the seed ; and for many years afterwards my practice was to well wash the seed corn in sufficient water to cover it, and allow all the lighter grains and seeds, &c., to float, and be skimmed off. In this way a complete separation of the sound grains from the diseased and noxi- ous matter that often accompany it takes place ; for the former all sink, while the latter float, and are easily separ- ated by well stirring and skimming. From this practice I 26 CULTURE OF FARM CROPS. found all the success I ever had from using poisons ; in- deed, I may say much more, for in this way all that was obnoxious was more easily got rid of. " It is idle to suppose that any mineral poison can be destructive of uredo, which is known to have a vegetable growth with the grain, and yet be innocuous to the seed corn, the germ of life being the same in both. " I believe the practice of poisoning bread corn is one that greatly calls for repression. The practice of washing and drying wheat after it has been prepared for seed, and then throwing it into the bulk for market, your readers will see is not unlikely to often occur, and who can tell what mischief may not spring from allowing arsenic to be used for such purposes 1 " The following from "Sell's Weekly Messenger:" — " The Eev. T. W. Booth, Vicar of Friskney, in the county of Lincoln, has written a letter to the Times, which is cal- culated to convey the impression that the custom of farmers in using arsenic for their seed-wheat is dangerous, perhaps malicious. The Eev. gentleman states that he has known crows and game to have been poisoned by it, and recom- mends swimming the seed-wheat instead. The object of farmers in using arsenic is, of course, to prevent smuts, and though there are numerous specifics recommended for the same purpose, arsenic is found to be the surest preventive. The writer of this has for 30 years used arsenic for seed- wheat, at the rate of 1 Ib. dissolved in as much water as will saturate three sacks, the wheat being afterwards dried with quick lime ; and during that time there has been no evidence of either crow or partridge having been poisoned. And we see daily proofs of this statement ; for as soon as the drill commences to deposit the seed- wheat in the ground the crows at the same time commence to dig it up again if not carefully tended (and often, in spite of this, much loss is sustained); so that if the seed prepared with arsenic would really poison crows, the dead birds must be seen somewhere. On the other hand, it cannot be denied that a stronger application of arsenic or strychnine would ren- INJURIOUS ACTION OF LIME. 27 der wheat poisonous, but this would be for a malicious purpose, and not in the ordinary course. Now, with regard to swimming wheat in salt water, the great use is, that you are enabled to skim off noxious seeds which the dressing- machine has failed to separate ; but in this case the old system of sowing by hand must be adopted, as it is scarcely possible to get the seed sufficiently dry to pass the cups of the drill; and, again, the process is slow and dangerous. It is dangerous, because if a quantity of wheat be steeped a day or two beforehand (which must be the case if the drill is required), the weather may become adverse either by excessive rain, snow, or frost, and the seed so prepared cannot be sown, in which case it would become spoiled; and, moreover, in wet seasons, when the land is wet and the wheat in middling condition, the additional moisture caused by swimming is injurious." 13. As to the injurious action of lime upon tlie germinat- ing powers of the seed, there appears to be in the minds of some authorities no doubt. " Unless," says a writer in a Canadian journal, " it can be known that lime serves other purposes than merely drying it for the advantage of handi- ness in sowing, I have' reason to think that its use for this purpose does harm oftener than we suppose, and that if its application, in conjunction with the wetting or damping, does kill all that is sickly, it may, and does under some circumstances, injure the vitality of the best of seed. It is a well-known fact that kiln-dried grain does not grow well; and the practice of farmers in scrupulously steeping and liming no more seed than they expect to need within ten or twelve hours, and washing off the lime of any por- tion more than they can use in one day, that they may not lose it the next, is good evidence that lime, in a new slaked hot state, adhering to damp grain, has a similar effect to kiln- drying — burns and destroys its vegetation power. I remember of having once heard it remarked by a shrewd farmer that he suspected ' that liming of the wheat to be no better than it was called.' " I had always a desire to satisfy myself of the doubts 28 CULTURE OF FARM CROPS. I entertained of the efficiency of the liming process. In Canada I resolved on giving myself the benefits of my doubts, and sowed half of a field of wheat with seed im- mersed and dried with lime, and the other half with wheat just as it came from the thrashing-mill; my object being, not to test the smut question, but whether wheat thus limed was in any degree injured in vitality by it. The re- sult demonstrated my doubts to be correct : the steeped limed seed brairded, or came up, much thinner — I think about a third thinner — than the portion from the seed which was not washed and limed, but sown as it came from the mill. Another circumstance in the case threw addi- tional light upon the question. I filled my hand as full to cover the same ground as I had elsewhere, and put equally as much seed on the steeped and limed as in the other portion, but what surprised me most was to see it come up so much thinner than I had ever seen the same quantity of seed produce elsewhere, and with this considera- tion in its favour, viz., that of fine growing weather (it being spring) and no drawbacks that attend the growth of winter wheat. This case satisfied me that lime does thus destroy, in some degree, the vitality of wheat. It was a plain experiment — sowing with and without liming — the limed portion was too thin a crop, and the unlimed was a thick-standing, good crop. "I believe in the preventive in question for smut, and I also believe liming of wet or damp wheat to be injurious to its vegetative or producing qualities." On the same subject a writer in the Prairie Farmer has the following : — " We may say that we do not believe it strictly necessary that lime, in addition to brine, should be used to destroy this parasitic fungus — it only makes assurance doubly sure, inasmuch as experiments have proved that lime water alone will destroy it. If wheat is allowed to stand in brine that will float a hen's egg, twelve hours, we should have no fear of smut if no lime touched it ; and we should have no fear that fresh, thoroughly slaked lime, applied to dry it, would affect the vitality of any portion SOILS FOR GROWING OF WHEAT. 29 of the seed that would ever germinate. It is possible to apply lime before it is completely slaked, and in that case it might affect the seed disastrously. Our correspondent should remember also that limed wheat is more bulky than that which is not limed — that the hand can hold fewer kernels in consequence; and it seems to us quite as pro- bable that the seed did not germinate because it was not sown, as that any of it was destroyed by the lime. We do not think his experiment establishes his doubts at all. Pure water, if administered to the seed in sufficient quan- tities, will clean it of this parasite, but salt and lime are more efficacious, and we think quite as harmless to the seed. Plaster or gypsum is a good substitute for lime as a drying material. It is less offensive in its effect upon the hands." CHAPTER THIRD. SOILS FOR GROWING OF WHEAT PRACTICAL MANAGEMENT OF ROTATIONS. 1 4. As regards the nature of the soil upon which wheat may be grown, it may be said that while almost every de- scription of soil may produce it, those soils nevertheless are best adapted to it which are more or less clayey. Heavy lands are, indeed, generally classed as wheat lands. But if the preparation of the land is properly attended to, wheat may be grown to the greatest perfection upon almost every soil. But while each variety of soil involves some differ- ent mode of preparation, there are certain points which must be attended to in all soils. These essentials are, first, "thorough drainage;" second, "complete cleaning from weeds;" third, "proper rotation of cropping;" fourth, "judicious manuring;" and fifth, "an entire change of seed from hot land to cold, and from cold land to hot." This change of seed will always be advantageous, and espe- 30 CULTURE OF FARM CROPS. cially from hot to cold soils, in which case it will frequently bring the harvest a week earlier. Wheat is generally taken after clover, the roots of which, becoming decomposed, yield nutriment to the wheat plants, while they give that solidity to the soil which the wheat plant requires for its healthy development. It has sometimes been noted that where the clover plant has failed the wheat plant succeeding it has failed also. These instances do not often occur ; when they do, they show an adaptation of the two plants to each other, or a mutual sympathy which justifies the correctness of the practice so generally followed of making the wheat follow the clover. We have said above, that according to the nature of the soil so is its management. 14. We purpose now to bring under review the various classes of soil, and the management which their pecu- liarities involve. And first as to clayey soils. Upon these soils a full summer's fallow is occasionally resorted to as a preparation for the crop, more especially when the land has got into a foul state with couch grass, &c., &c., and to which cleanness cannot be restored with the partial fal- lowing which is available through the growth of green crops. It is also to be noted that this thorough summer fallowing has a good influence upon the soil, as it allows the atmospheric influences to more perfectly decompose its con- stituent parts ; so much so, that in some instances it has been observed that more advantage has been obtained by giving a thorough summer's fallow without manure than by a partial fallowing with a plentiful supply of dung. On the heavy lands of the Midland Counties, where a summer's fallow is followed, the land, towards the end of July or beginning of August, is thrown up into two bout stetches — after, of course, it has been thoroughly pulverized and cleaned from weeds — one yard wide, and manured with 8 to 10 cart-loads per acre, precisely as if for the turnip crop. Others spread the manure over the land, and plough it in, so as to have the stetches or furrows from 2 to 8 yards wide. In both of these cases the land should re- main untouched till the time of sowing, although it often PRACTICAL MANAGEMENT OF SOILS. 31 happens, where the latter mode is practised, that the weeds come up so strong, that before sowing it is necessary to cut them up with the horse hoe, as the harrow would be ineffectual in removing them. Where the former method is adopted, the plough alone is sufficient to remove the weeds. The seed is sown under the furrow, in what is called the " spraining system," one seedsman sowing to two ploughs, the ploughs merely reversing the furrow formerly dunged. The seed should not be sown when the soil is too dry or in a dusty condition, as the young plants are in this state of soil apt to become "root-fallen ; " and even where the soil is of a closer texture and this is not likely to happen, wheat does not nourish so well as when put in after rain. Indeed, Mr. Roberts — an authority on this point — says that land cannot be too wet for sowing wheat provided it works kindly, and the seed can be well covered. There are, however, some soils of sandy clay which should not be worked or stirred while wet, as they will run together and form a hard crust of soil, through which the young plants have a diffi- culty to penetrate. The best period for sowing on soils of the kind now under description is from the last week in September to the middle of October ; the plants rarely be- come winter-proud on soil of this description. We have said that under draining is one of the essentials required in all soils ; some maintain that this being attended to in clayey soils, there is no necessity for upper water furrows. Mr. Roberts says that he thinks this a mistake, for he finds that upon soils of this nature the surface water does not go off sufficiently quick without it. 15. When land of this kind now under consideration, clayey or tenacious, has been got into a high state of cul- ture, it is frequently made to carry a crop of turnips or mangolds. But these crops cannot always be got off the land in time, so that spring wheat has to be sown upon it, and the seeding delayed till January or February. White tur- nips grown upon the fallows, and fed off during Octo- ber and November by sheep, form an excellent preparation for wheat on clayey soils in high condition. In cases 32 CULTURE OF FARM CROPS. where tins plan is adopted, the following is the rota- tion : — First Year, Fallow for turnips. I Third Year, Beans or pease. Second Year, Wheat. | Fourth Year, Wheat. The next round being — Fifth Year, Fallow for Swedes. I Seventh Year, Clover. Sixth Year, Barley. | Eighth Year, Wheat. 16. Wheat on clay soils is often sown after beans; the dung is applied to the beans, and the crop well hoed, so that the land is clean for the wheat — hence the advantage of sowing the beans in drills. This plan of dunging the land for the beans is better than dunging the land directly for the wheat, which practice often is a cause of blight. By having an intermediate crop of beans the blight is likely to be prevented, and a better crop, both of beans and wheat, secured. "Where farm-yard dung is scarce, and cannot be applied to the beans, rape-cake, at the rate of 8 to 10 bushels per acre, may be drilled in at the sowing of the wheat. On the heavy clay lands of Norfolk and Suf- folk the wheat follows either clover or beans and pease, barley being the crop immediately succeeding the fallow, so that the rotation stands thus : — First year, Fallow. Second Year, Barley. Third Year, Half clover, half beans or pease. Fourth Year, Wheat. 1 7. The best farmers apply dung to the pulse, carefully hoeing the crop. The wheat is drilled after the beans, al- though by some it is dibbled after the clover. The clover layers are manured heavily with, farm-yard dung, either on the young plants during winter, or a short time previously to turning over the land for wheat; the wheat comes kindlier, and the clover plants are benefited by the plan of dunging the clover in winter. It may certainly be ob- jected to this system that the manure is exposed all the winter to the atmosphere, and that much of its fertilizing properties may be wasted ; on the other hand, it may be PRACTICAL MANAGEMENT OF SOILS. 33 said that the clover will take what its growth specially re- quires, leaving the other constituents to be assimilated by the wheat. This system of grain-growing, as practised by the best farmers of Norfolk and Suffolk — the homes, par excellence, of the " drill husbandry " — might be followed with advantage in other districts of England, where the furrows or stetches are wide, and brought up to an enor- mous height in the centre by repeated ploughings. This absurd form and width of the furrows brings about many disadvantages ; the grain is always of unequal quality, being very inferior towards the furrows as compared with that at the crown of the ridges, and, from the width of the stetches, the horses tread upon and poach the land very much. In Norfolk and Suffolk the stetches are flat, or but slightly rounded, and are of such width that the drill takes the stetch at a bout, while the horses in this, as in all the succeeding operations of harrowing, &c., walk in- variably in the furrows, so that all treading on the land is avoided. Those farmers who love the high-backed furrows should remember, or, if not knowing, should be made aware of the fact, that the raising of grain crops on the flat in place of upon ridges is the tendency of improved agriculture. 18. Light, Chalky, or Gravelly Soils. — On soils of this kind the wheat crop generally follows the clover or trefoil. Should the clover fail, a crop of early pease is substituted, and on these being removed, cole-seed or tares or white mustard is laid down, and eaten off by sheep in the au- tumn. The land thus prepared succeeds well with the wheat. To prevent the wheat plants being thrown out, or the ravages of the wire-worm, the soil is consolidated either by the use of the roller or by treading with folded sheep. Light soils are greatly improved by being mixed with clay, and the process is considered essential where a good crop is desired. Light lands require more seed to the acre than heavy soils, and the end of October is the best time for sowing. In light soils 10 pecks to the acre is not an un- usual quantity. 19. Rich, Deep, Loamy Soils. — Wheat in soils of this c 34 CULTURE OF FARM CROPS. kind is successfully cultivated after potatoes, the potatoes being got oif the ground not later than October. In many districts, as in East Ham, Romford, Barking, Edmonton, and Enfield, it is no unusual thing to grow potatoes and wheat alternately for many years. And we may note that we have seen the practice adopted in the north, of England with remarkable results. But where this species of what may be truly called hard-cropping is followed, it is necessary to manure the potatoes very liberally. The potatoes may then yield 300 to 500 bushels per acre, and the wheat from 30 to 40 bushels. Four pecks of seed per acre on this quality of land will be sufficient, and care should be taken not to sow it earlier than the end of Oc- tober or the beginning of ISTovember, as, if it is sown earlier, the plants are almost sure to become winter-proud. Where a rich, strong loam contains a larger proportion of clay, wheat and beans may be, and are, sown alternately, and successfully too. In some cases where the beans are kept perfectly clean by repeated hoeing, ploughing the land for the wheat is often superseded, all that is required to be done being to harrow the land previous to dibbling or drill- ing the wheat. 20. Peaty Soils. — To enable soil of this character to bear wheat, it must first be thoroughly drained, so as to get it in some degree consolidated ; thereafter it must be mixed with clay or inorganic matter, and well treaded, rolled, or pressed before and after sowing. In the fens of Lincolnshire and Cambridgeshire, where peaty soils are thus improved, the improvement in the quality 01 the wheat keeps pace with that of the land, approaching that grown in sandy and loamy soils, while the quantity greatly ex- ceeds that grown on light sands or gravels. A process, which, appears adapted for the preparation of peaty soils for wheat, is to plough the land shallow, drill, roll, and hand-dibble the seeds in the grooves made by the roller, finally covering the seed with a harrow. Solidity of soil is absolutely essential in peaty soils. Dibbling the seed — giving, as it does, a stiff straw — appears to be the best adapted for peaty soils. PRACTICAL MANAGEMENT OF SOILS. 35 21. Fresh broJcen-up grass land. — On this land oats are preferred to wheat as the first crop ; but when the surplus vegetable matter of the soil has been reduced by burning, tillage, and the mechanical application of suitable earthy matter, wheat can be grown of good quality. In conclud- ing the remarks upon the various soils, let it be remembered that in all soils prepared for wheat, it cannot be too stale or solid, provided it be free from weeds, and the surface- soil sufficiently pulverized to enable the seed to be easily covered. 22. We now draw attention to an admirable Essay, by Mr. Roberts — 'previously named — in the Journal of the Royal Ag- ricultural Society of England, on the management of wheat ; and first, as to the " Treatment of the Crops in Spring as to pressing and hoeing" Pressing in the dry weather in spring is especially useful on loose and open soils, and on soils which require draining ; for where water saturates the surface soil, it becomes increased in bulk during winter by its conversion into ice, raising the soil, and tending, when a thaw comes, to throw out the plants. When soil treads loose in the spring, it is important to use the heavy roller. Crosskill's Clod-crusher is also highly useful, but it can only be used in very dry weather. Folding with sheep is also useful. In the fens the loose soil along the drills is consolidated by men and women trampling along them. Where the land is foul when the seed is sown broad-cast, the hand-hoe must be unsparingly used to keep down the weeds. Where drilling and dibbling has been the mode of sowing practised, the horse-hoe can be used with advan- tage. Whether weedy or not, hoeing is practised by some, and doubtless with advantage, as it enables the plant to take a fresh start in the loosened soil. Hoeing should be begun as early as the weather in the spring admits. Har- rowing is often practised with success, more especially where the land is crusty and the roots have struck deep in the ground. Any mode indeed of loosening the surface-soil in spring enables the plants to take a fresh start and to im- prove amazingly. Harrowing light sand and gravelly soils 36 CULTURE OF FARM CROPS. obliquely, or at right angles to the drills, is peculiarly ad- vantageous, tending, as it does, to destroy the poppy and other weeds which infest such soils. To destroy the poppy, it has been recommended to harrow when the surface-soil is slightly crusted with frost. If the plants are extremely luxuriant in spring, it is beneficial to ' flag ' them, as it is called ; that is, to cut off, by a scythe or bagging-hook, the blades or leaves from the stalk ; this should be done early, not later than May, as if done later, the ears, or. the part which would form the ears, might be cut off. 23. In an able paper, by Professor Tanner, in the Jour- nal of the Eoyal Agricultural Society, on " The Mechanical Condition of the Soils favourable for the Growth of Seed," there are some practically valuable remarks in connection with the wheat crop, to which we now direct attention in the following condensed epitome — " The heaviest clay soils are generally prepared by bare falloiv ; when this is properly managed, the soil becomes broken up by the winter s frost, baked by the spring and summer's sun, and crumbled by the descending rain and the gentle dews, and in combina- tion with its implemental stirring and inversion, it is finally changed from a close adhesive bricky character to one in its pulverised condition, fitted for the wheat plant. In some very heavy soils the bare fallow is essentially ne- cessary for the wheat crop preparation. The degree of fineness for the wheat crop, to which the soil is to be re- duced in heavy clays, is a matter in which there is consid- erable diversity of opinion ; but the general opinion seems to be that the land should not be rolled so as to bring it into a fine state unless the land is foul, and it is necessary to give the seeds of any weeds which may be in the soil a better opportunity to grow. Even in such cases, risk is run in wet weather of having the soil pasty • so that it is better to keep the soil in a small lumpy state than in a dusty one. The last ploughing of heavy soils should leave the land in ridges, and the ploughed earth should not be broken down till sowing. It is advisable to prepare these soils early in the season, while the earth may be easily PEACTICAL MANAGEMENT OF SOILS. 37 thrown together in a dry state, and thus left till sowing." Professor Tanner agrees with Mr. Roberts as to the advan- tages of having the stetches or furrows narrow, so that they may be covered at one bout with the harrow or the drill, and the horses may walk in the furrows. If the land has been prepared in good time and in good condition, and the weather favourable, Professor Tanner would prefer to sow the seed broad-cast, rather than run the risk of losing the proper time and condition of soil by choosing the slower operation of drilling. In all clay lands of a strong charac- ter, it is of the utmost importance to avoid the poaching and treading of the land by the horses, and to have the seed in, as early as the climate of the locality will permit of. For so attractive and retentive of moisture is clay of this character, that it not only absorbs it from the air, but when rain falls its pores are filled up, and if pressed upon a firm adhesion of its 'particles is the result ; the feet-holes of horses retain therefore the moisture long after the land is generally dry ; and the contraction of the soil when dry- ing, and its expansion while being wetted, have a most deleterious influence upon the growth of the plant. When the seed is got in it should be harrowed, but only suffi- ciently to cover the seed, not to make the surface smooth, and rolling should be certainly avoided. If a fine surface is obtained either by over-harrowing or by rolling, the first heavy rain which comes, forms a muddy coating which, in dry weather, becomes a dry crust. This crust prevents the play of the atmospheric influences upon the rootlets of the plants, and hinders their tillering. The surface should therefore be left in a rough state consistent with the actual covering of the seed. These rough clods act as good shel- ters to the young plants during the hard frosts and the biting winds of winter and early spring, and will mellow down into a fine tilth as genial weather approaches ; so that when spring-rolling is carried out, a valuable help will be given to the young plants. But while the farmer is counselled to leave his lands rough, it is not meant thereby that he has to leave it so rough as to be negligent or slo- 38 CULTURE OF FARM CROPS. venly in appearance ; a neatly finished corn field is an indication of general good management. So that while the surface is left rough, labourers should be sent in to finish neatly off all the furrows and water-gutters, which latter should be given to all lands of this class, even although carefully under-drained. The above remarks have reference to the mechanical condition of heavy soils where a ' bare,' ' naked,' or ' summer fallow ' — for by all these names is it known— is the practice. We now come to what Pro- fessor Tanner says on the management of clay soils where the wheat crop is preceded by a crop of autumn food or early roots, as rape, cabbages, vetches, mangolds, or pota- toes ; the soils where these crops are taken may be desig- nated medium clays, being of a somewhat lighter character than those heavy tenacious clays where the bare fallow is the best mode of preparation. Where beans has been the preceding crop, the land having been hoed, will not be very foul with weeds, and may therefore be looked upon as in pretty good condition. It may be the better for being skimmed and having the weeds burnt ; where this cannot be done, through the ground being too hard, the plough may be used, preceding its operation with the fork, so as to get out the couch grass. Where summer tillage has been well carried out, a single ploughing is all that is necessary. Where the autumn food, as rape, vetches, has been con- sumed by sheep on the land, and it has in consequence of rain falling become very hard, two ploughings may be necessary, and if so, 1 0 to 1 4 days should elapse between the two ploughings, so as to allow the soil to regain the firmness necessary for the seed. It is always, however, well where this second ploughing can be avoided, for it does away with or tends to do away with the solidity of seed-bed which wheat requires. It is seldom, however, that in stiff clays there is any difficulty in getting this solidity of seed-bed, although after vetches, the land is apt to be puffy ; but this is corrected by feeding sheep upon it to consume the crop as it stands. 24. Where the wheat has to be sown after an autumn PRACTICAL MANAGEMENT OF SOILS. 39 crop of green food upon light land, it is requisite to be very careful as to the firmness of the soil. It is generally objectionable to sow wheat upon this plan in the southern districts, though it is often practised in the northern dis- tricts of England ; but there, measures are specially taken to give firmness to the soil. The crops of autumn food which in these districts usually precede the wheat are rape, turnips, and rape, and common turnips, and these are always consumed on the land by sheep. After the land is ploughed, the presser is taken over it ; but if this does not give the necessary firmness, sheep may be turned in to tread it down, thus giving a consolidation which no rolling can ever give it. Should all this fail in consolidating the soil properly, the only way is to change the cropping, and take the wheat after clover, which after all, in such soils, is the best preparation for the wheat crop. But as there is in the northern counties a strong objection to wheat after clover, the only mode at disposal is to sow the seed while the land is wet, which will secure the firmness required. A clover ley, well inverted by the plough, offers a fine firm furrow; hence its advantages for the wheat crop. The furrow is all the better for lying for some time after inver- sion, so that the seed may be sown upon a ' stale furrow.' It is also advisable to use a skim coulter with the plough to assist in burying the turf completely, otherwise the clover is apt to spring up between the furrows, which is objec- tionable. 25. As the land becomes lighter, on which it is proposed to raise a wheat crop, the laiid-presser comes in to aid most opportunely and efficiently in getting a consolidated seed bed. Professor Tanner states that he has frequently, with advantage, used a small drill in conjunction with the presser for sowing clover ley, especially in wet seasons when the soil is disposed to be rather adhesive. Such land, he says, can often be ploughed up quite dry enough for imme- diate sowing ; but before a sufficient breadth of it can be prepared for a day's work of a large drill, it gets too wet to be worked, and often has to lie therefore a considerable 40 CULTURE OF FARM CROPS. time before drilling. But by the use of one of these press- drills, the ground can be pressed, drilled, and harrowed, close after the plough. 26. Professor Tanner draws special attention to an important condition in wheat culture, namely, the degree of moisture in the land. The seed he conceives should be sown 011 clay soils as dry as possible, for moisture will be sure to follow rain. Where the land is on the contrary wet when sowing is performed, the particles of soil cohere together. There is less objection to the working of light soils in a wet condition. It is not often, the Professor re- marks, that sowing is carried on in the south of England in wet weather ; but yet he has seen it done, and while the land was quite muddy; nevertheless, the crop was the best on the wetted land j but he judiciously remarks, this which may be safe upon one soil will often be very injurious upon another apparently of the same character. The pro- portion of sand or grit which soils contain is that indeed which separates those soils which can be worked without injury while moist, from those which cannot be so done. In sandy or gritty soils the germination of the seed is little delayed, even although sown when wet. 27. Climate, the Professor points out, is that which almost alone decides the time when seed should be sown, " for neither the character of the soil, proximity to the sea, ele- vation, nor any other individual influence decides the prac- tice, but that peculiar knowledge which renders local experience alone worthy of confidence." October and November are the usual months for sowing in the principal wheat districts ; but the period from the middle of Septem- ber to the end of the year must include all the sowings of the autumn wheat. The more exposed the situation the earlier the time, and the greater the quantity of seed to be observed and required. In the mild districts of the west of England the sowing may be made at the end of December without any damage to the crop \ but in northern districts, seed sown so late would nearly all miss, and those which would germinate would produce wretched plants. The rule which PKACTICAL MANAGEMENT OF SOILS. 41 regulates the quantity of the seed, Professor Tanner says, is this — " The early sowings require less seed, whilst for the later sowings, the quantity should be gradually increased ; and again, as the soil and climate become more favourable to the growth of wheat, less seed becomes necessary. The iirst sowings will take 5 to 6 pecks per acre, whilst the latest will range up to 8 pecks, and on poor land, up to .is many as 1 0 pecks. The influence of soil upon the quan- tity of seed to be sown is very marked, the richer the soil the less the seed required ; this is accounted for by the supposi- tion that in rich lands the plant tillers better than in poor soils, throwing up a greater number of poor stems. In poor land, therefore, more seed is necessary to increase the stems and to enable the crop more thoroughly to search for food in the soil." 28. The depth to which the seed should be sown depends upon the closeness of the soil, and therefore changes with different textures of soil. On loamy soils, a depth of one inch is found to be the best, but in proportion as the soil becomes lighter should the depth be increased till it reaches 1J and 2 inches. The mode of ploughing in seed-wheat with a three or four-inch furrow, the Professor says, is clearly wrong, for at such a depth, the plant will not es- tablish its roots in the soil, and its growth upwards will be much delayed. If any difference in the depth is to be made in loamy soils, it should be made thus : — the early seed should be sown the deepest, as then there is plenty of time for the growth of the plants, and a deep growth insures a firmer root ; but no variation in depth should exceed half an inch. The lighter the soil the greater the depth, for the firmer the root obtained. 29. In sowing Spring Wheat the soil need not be so firm as for autumn wheat ; but the difference is only one of degree. For when wheat is sown upon land not suffi- ciently firm, the plant fails in the severe weather of winter; the more solid the bed, therefore, the firmer the hold of the roots in the soil ; so that frosts cannot dislodge the plants. The great necessity then for a firm seed-bed in autumn arises 42 CULTURE OF FARM CROPS. from our desire to insure stability of position of the plant during winter. This necessity does not exist so markedly in spring ; the preparation of the land in this season for the wheat crop, is therefore much less troublesome and costly than that of autumn. When the roots of the pre- ceding green crops have been removed from or consumed upon the land, it is ploughed once, and the seed is sown as soon as a favourable opportunity presents itself, so as to have the soil in good dry working order. A second plough- ing, for the reasons already stated, is seldom given. Spring- wheat should be sown early; none, excepting theApril-wheat, should be sown later than February in the eastern, and March in the western districts of England. We have thus given a rapid resum£ of Professor Tanner's paper, so far as it relates to the wheat crop. We now, in concluding this chapter, do the same office for a prize paper by Mr. J. P. Pratt, in the Journal of the Bath and West of England Society, with a view to draw more special attention to the writer's system of managing very heavy clay lands, usually placed under the summer fallow system. 30. The ordinary system pursued by occupiers of poor clay lands, in which the working of the summer fallow is generally deferred till May, when the first ploughing is then given, admits, as Mr. Pratt points out, " of no improvement of the land for wheat, or indeed for any other crop ; for naturally the same results will follow, year after year, while if possible, its stubborn and adhesive texture is increased during the two years' rest, during which the land is gene- rally under grass as it is called (and truly so, for it produces nothing), by the winter rain constantly hammering on and hardening its surface, shutting up every aperture from the beneficial effects of frost and sunshine, thus defeating the very work of amelioration which nature has provided." Mr. Pratt then details his mode of working a system of fol- lowing from autumn through winter, on all the heavy lands of his occupation, and of which we now offer an epitome. 31. On the best description of land, Mr. Pratt grows mangold-wurzel and the artificial grasses, alternately, with PRACTICAL MANAGEMENT OF SOILS. 43 wheat. The foundation of this course of cropping is laid by ploughing and subsoiling, to a depth of fourteen inches, the ' ley wheat erishes,' doing this as soon after harvest as possible, and has sometimes been done as early as August. The rough surface and weeds are exposed to the sun- shine of September, sometimes, as above stated, of August, which opens up fissures into which the rain of winter de- scends, passing through and between the clods, and when frost conies, helps the work of disintegration wonderfully. The influence upon the clods in this way is very different from that obtained by the usual fallow with its hard sur- face, upon which the rain beats and the frosts act only superficially. In February or earlier, dry weather should be chosen to ' change sides ' with the fallow and expose the under portion to a similar process. This helps to evapor- ate cold winter water, and to raise the temperature of the soil. Mr. Pratt draws attention here to another and ' ap- parently incomprehensible, but nevertheless, perfectly sound advantage ' obtained by the drying of the soil, for the drier the clods are made in winter and in early spring, the bet- ter they retain the moisture in the dry summer months. March winds and the subsequent frosts operate again upon these reproduced clods, produced by changing sides with the fallow as before stated, and bring them into a fine tilth in remarkable contrast to the hard tough shining furrow of ' brick earth exhibited, where the ploughing and fallow- ing have been deferred, as is usually, or often the case, till spring.' The labour of preparation for the mangold-seed is trifling, comparatively, and the horse-hoe finishes the work of the summer fallow. Since Mr. Pratt has adopted this system, he has effected a large saving, in the spring, of horse labour, and the work of clod-crushers and rollers is in a great measure superseded by the work of natural in- fluences.* The few remaining clods left here and there, * See Mr. Stephens' work, " Tester Deep Land Culture " — Black- wood & Sons — for a most suggestive chapter on the influence of the atmosphere in reducing clods to a fine tilth, and also for a very re- markable prophecy or suggestion that, by the extension of deep cul- 44 CULTURE OF FARM CROPS. over the field, are beneficial rather than otherwise, inasmuch as they hinder that cementing action which wind and sun (after rain) have upon line mould \ while they act also as shelter-clods for the young plants, and retain moisture near them, while they finally get themselves reduced to fine mould for the roots to penetrate in. The same system ap- plies to every description of heavy land, from the richest to the poorest ; rape, however, being taken in the case of the poorest soils in place of mangold-wurzel. Eape, Mr. Pratt states, surpasses all other fallow crops for heavy land ; for, in addition to its possessing deeply penetrating roots which open up and drain the soil, it comes to such an early maturity that ample time is allowed to have the land pre- pared for the succeeding wheat crop. None need, he says, be deterred from growing rape from fear as to the poverty of the soil. Mr. Pratt has proved, by successful practice in a cold and undrainable clay at a high elevation, and which had been abandoned as worthless, " that when a crop has once been grown, it is much easier to grow a second crop after, for the soil is by these means raised a stage in fertility, the climate is improved, and the temperature of the soil raised by the circulation of the air through it by means of the fibres of the rape plants ; and if further evidence be requir- ed, 35 bushels per acre were produced, where 20 had never been attained before." 32. The preparation for wheat after seeds, alike with that after roots, extends, in Mr. Pratt's system, over the whole previous year. Indeed, the whole system of cultivating both corn and roots is so entirely bound up, and each part of it is so dependent upon the other, that Mr. Pratt does not know how to separate the two. In Sep- tember, or as soon after harvest as showery weather offers, ture, clod-crushers and the like would be superseded. "We have our- selves, for a long time, advocated the notion that the imposing array of implements and machines are, many of them, the mere necessities of a bad system of culture. By bringing in a more philosophical system, as deep culture, we shall reduce, we think, our implements to a minimum, wry tnuch below the present standard. PRACTICAL MANAGEMENT OF SOILS. 45 the clover erishes or ley should be well manured on the surface with farm-yard compost, or from 3 to 4 cwt. of guano. Care must be taken not to allow the sheep to nibble the plants too closely, whilst they should not be allowed to pasture later than October. When the clover crop has to be grazed off the same land, it is especially de- sirable, in the case of the grass seeds, to defer the grazing till the plants are 8 to 10 inches high. The greater the surface vegetation of the seeds the more nourishment they draw from the atmosphere. Indeed, every effort should be made to increase, by every possible means, the amount of clover vegetation above the surface, and the corresponding roots below, so that an increase of food for the coming wheat crop may be secured. 33. The ploughing of the rape and turnip or mangold wurzel erishes must be of a shallower description than that on the clover ley. The ploughing should, for wheat, in all cases be in the direction of the field's slope, for each furrow, if well turned, acts as a drain. And where the soil is very wet and tenacious, with a flat situation, it will be advisable to plough it up in beds of 13 feet wide, these being gra- dually formed by a rounded slope from the centre, or "bye," to the bottom furrow. After ploughing, the rape erishes will be sufficiently prepared for the seed by a double stroke of the harrow in the direction of the furrows, the drill after- wards proceeding across them. The leys will probably re- quire more harrowing, but in all cases the amount of harrow- ing will increase or diminish with the dryness or wetness of the season. These operations being all completed, the fur- rows are all cleared, and free vent made for the water. Other furrows must also be made through every hollow. Mr. Pratt gives some notes as to the varieties of seed wheat, the times and mode of sowing, &c., &c., but these points we have already discussed. 46 CULTURE OF FARM CROPS. CHAPTER. FOURTH. DIFFEKENT MODES OF SOWING THE SEED THICK AND THIN SOWING. 34. There are three methods employed in sowing the seed — (1.) Broadcasting; (2.) Drilling; and (3.) Dibbling. Of these three the first two are the most generally prac- tised, the third being quite exceptional. Broadcasting has the great advantage of being quickly done, so that in un- certain, showery weather, where the land is already pre- pared for the sowing, the seed may be got in while the weather remains good, while by the slower operation of drilling the opportunity of fine weather may be lost. The great objections to broadcasting are the great quantity ot seed it involves, and the encouragement given to the growth of weeds. These are both obviated, at least to a consider- able extent, by the drilling system, the quantity of seed being less, while the spaces between the drills enable the hoe — hand or horse — to be worked in spring. The quantity of seed can also be regulated by the drill to the greatest nicety. An objection to the drilling system has been made, and doubtless in some districts truly obtains, namely, that in consequence of a loose, continuous furrow being made from one end of the drill to the other, the ravages of the wire-worm are aided. This can be avoided, however, by running a Crosskill roller across the line of the drills, thus breaking up each drill into short spaces. The great point is to stop the continuity of the path of the wire-worm and to force it to come up to the surface at each plant rather than move from plant to plant. " Dibbling " is just as much in advance of drilling as drilling is in advance of broadcasting, so far as the saving of seed is concerned and the capability of keeping the growing plants clean and free from weeds. Taking a review of the circumstances attendant upon the growth of the wheat plant, there can be no doubt that the mode of sowing which dibbling pre- sents to us does indubitably enable this growth to be best MODES OF SOWING THE SEED. 47 developed. We dismiss our notes of its advantages at present by simply pointing out that, not only by it do we enable the plant to tiller well out in the early stages, and to give plenty of room for the later stages of its growth, and for the light and air to play around it, but that we obtain a stronger plant, finer straw, and richer ears. There is one fault, however, which we have found in our own practice to be dependent sometimes upon the dibbling, namely, the rust which the plants are liable to. We say sometimes, for not always is this rust an accompaniment of dibbled grain. In some instances we have also noticed that while the deteriorating influences of rust upon broadcast and drilled grain upon its quality were very marked, this was not the case in the case of rusted dibbled grain. Indeed, there has been always something very different — on a close inspection — between the kind of rust which infects dibbled grain and that which we have noticed in grain sown in the usual methods. What that difference is we are not at present prepared to say, but it appears to us as likely that the freer access of light and air to dibbled grain, as com- pared with broadcasted or drilled grain, does bring about a less virulent kind of rust. Certainly, so far as we have noticed — and we have examined no small number of spe- cimens— the influence of rust upon the grain of the dibbled wheat has in no instance been so marked as in the case of grain broadcasted or drilled. 35. The depth at which the seed is sown, and the width between the drills, exercises a most important influence upon the prospects of the crop. The experiments of Mr. Hallett the reader will find explained in Chapter Sixth. We meanwhile place before him a few opinions of authorities as to the width or distance between the drills — the first of these being from the pen of Mr. Lawrence of Cirencester : — " I had observed some years ago, that practically the question of width lay between 7 and 9 inches, and the quantity of seed varied between 2 and 3 bushels per acre. Desirous of arriving at some conclusion on these points for my governance on my own farm, which comprises heavy 48 CULTURE OF FARM CROPS. and light land, I have, during the last five years, sown several half-acre plots in the same field, varying in width from 8 to 12 inches between the rows, and with from four to eight pecks of seed per acre. Any one who has tried such experiments will have found, on comparing those of one year with those of another in different fields, very per- plexing discrepancies arising from the variety of land some- times occurring in the same field, and other disturbing causes. It is therefore only by repeated experiment year by year in different fields that a reliable impression can be arrived at. The result of the experiments on my farm has been in favour of 12-inch intervals and six pecks of seed. The largest produce I had in any year was from four pecks of seed with 1 2-inch intervals. I may add, these experiments have been made indifferently on light stonebrash and tena- cious soils on stiff clay. During seasons in which mildew has been prevalent, I have observed that it has to a some- what greater extent attacked the straw of the 12 -inch than that with 8 or 9 inch intervals — a result I should not have anticipated a priori" 36. On this point of narrow and wide drills, the following tabular statement of the results of experiments carried out by Mr. Birch Wolf will be suggestive. The land was marked out in the centre of a 50-acre field of wheat, two plots being arranged of 5^ roods each, one plot being sown at the rate of 6 pecks per acre, with the drills 9 inches apart, and the other plot with 7 pecks per acre, the drills 7 inches apart : — 9-iNCH DRILLS.

It will also be noticed that the quan- tity of seed was not equal in both cases. Much of the value of experiments of this sort is lost through the inad- vertence or carelessness which prevents the simple rule being attended to, that the trial should be equal in all respects. Here the question to be decided was the influence of width of the drills upon the seed sown, and yet the quantity of this was not equal. In another trial by the Messrs. Dixon of Withani in Essex, the quantity of seed used in the two widths was very properly the same, at the rate of three bushels per acre. The width of the stetches or furrow was in both cases 10 feet, but one half of the stetches carried 19 rows or drills, the other half 13 rows. The whole quantity of land thus sown in equal divisions of 19 and 13 rows or drills to the stetch of 10 feet was 3 roods 37 poles. The produce was as follows: — Bushels. Pecks. Stones.

The soil was of a mixed quality, and the seed was of the variety known as " the golden drop." 37. The method of sowing generally adopted on the Con- tinent is the broadcasting but the more advanced agricul- turists are fast adopting the drilling, or, as they term it, " cultivating in rows " or lines. On the relative advantages of the two modes, we find that some of their leading men have experimented extensively, so that in this department, as in others connected with agriculture, we find ready to our hands much information that is more or less practically valuable, always, at all events, suggestive in our own prac- tice. The following, from the pen of M. J. A. Grand- voinnet, on the relative advantages of broadcasted (volee) and drilled (en ligne) crops will be useful in this direc- tion : — " A greater amount of work is really necessary to obtain D 50 CULTURE OF FARM CROPS. good crops if the com is sown broadcast, in comparison to the work necessary when the cereals are sown in drills, because a small amount of cleaning work required for each crop in turn during the proper time is more effi- cacious and more economical than a great amount of work done in a single year, and accumulated upon the single area of the roots, or other fallow ground crops. When the cultivation in rows is systematically followed in a proper way, and in a favourable time for hoeing with the hand and by horse-hoe, the earth is easily kept in order, and consequently gives its produce more regularly and more independently of the seasons than cultivating and sowing it at random, by which the cultivator has no more control or power as soon as he has sown the seed and harrowed it in. " Above all, in a soft soil which naturally is overrun in spring by many bad herbs, the cultivation of corn in rows ought to be beyond doubt adopted, because of the ease which it gives during the interlineary work to destroy bad branchy herbs, such as the wild vetch, &c., which destroy completely, in the course of time, the crop of wheat by taking complete possession of the ground. " Light soils, such as sandy earth, calcareous or gravelly, is also good for cultivation in drills. The error principally committed by sowing corn in these soils in rows is indubita- bly the use of too much seed, which gives a greater num- ber of plants than can vegetate and mature well there. In these light soils, drilling in rows ought to be adopted, and following the systematical use, careful of horse or hand hoeing, an operation which may be executed with much greater effect, and more frequently upon dry soils than on retentive clayey soils, however well drained they may be. " A fact too little taken into consideration by cultivators is, — wheat when uniformly sown in drills resists dryriess, preserves its colour much better for a. longer time, and gives a greater produce of grain in light soils than by being thickly sown. MODES OF SOWING THE SEED. 51 " This error of sowing irregularly has often, without doubt, had an unfavourable effect on the system of sowing in rows. Because if the uniform drills are not adopted in cultivating in rows, it is not astonishing that the results have been more favourable to sowing at random than to sowing in rows. " All farmers may have observed with what tenacity the plants in rows keep in the ground, compared to those sown broadcast ; this tenacity arises from the seeds having all been placed at the same depth in the soil, and accord- ingly all the plants are equally well rooted ; whereas by sowing broadcast, too thickly, the irregularity of harrow- ing brings about a great inequality in the depth of soil covering ; the weakest die, and give place to the stronger, until a proper proportion is left for each square. ' After having weighed all arguments for and against the sowing and the after culture and cultivation in rows, and by keeping count also of the very imperfect manner in which they have been very frequently done, and after hav- ing done the same for sowing broadcast, we think the conclusion is, that the advantage is decisively on the side of cultivation in drills. In 1786, Mr. Amos, a very clever cultivator of the last century, published his experience on the two systems of cultivation. For wheat he got the following results, the details of the expense of cultivation omitted — A hectare sown in drills. Produce— 31 hectolitres, 94 litres, at 18 fr., 97^ the hectolitre, . . . fr. 616 69 Expenses — Hire, seeds and expenses for cultivation, 161 44 Balance, fr. 255 25 A hectare sown broadcast. Produce— 26 hectolitres, 95 litres, at 18 fr., 97^ the hectolitre, . . . . fr. 513 94 Expenses — Hire, seeds and expenses for cultivation, 165 85 Balance, fr. 348 06 In favour of cultivation in drills, . fr. 107 19 52 CULTURE OF FARM CROPS. " Thus for three-quarters of a century cultivation in drills was, by experience, admitted to be more advantage- ous than ordinary cultivation. This fact proves very clearly the slowness with which agricultural improve- ments are adopted. " A similar experiment was repeated by Mr. Amos in 1791, and he got an equally favourable result — A hectare of Corn in drills, at the distance of 229. Produce — 37 hectolitres, 72 litres, at 17 fr., 25 c. the hectolitre, . . ; fr. 454 06 Expenses — Hire, seed and expenses for cultivation, 146 38 Balance, fr. 507 68 A hectare broadcast. Produce — 31 hectolitres, 94 litres, at 17 fr., 25 c. the hectolitre, fr. 560 64 Expenses — Hire, seed and expenses for cultivation, 145 61 Balance, fr. 415 03 In favour of sowing in rows, . . . fr. 92 65 " From these details it will be seen how it happens that where two farmers occupy the same kind of soil ; if the one cultivates in rows, he will have an advantage of more than 100 francs for each hectare of corn that he cultivates more than the farmer sowing his wheat broadcast, which proves, that success in cultivation does not depend so much on natural circumstances as on the skill with which the ground is cultivated." 38. Dibbling, or setting, as it is sometimes called, is by many spoken of as a new thing. It is not so ; in fact, its practice on an extended scale was commenced so early as 1765. In old magazines, and specially in the original re- ports of the oldest of all our agricultural societies, namely, the Bath and West of England — which reports, by the way, are now difficult to be had — we find abundant evidence given of the advantages of the dibbling or setting system. The result of the inquiries made by the secretary of the Society, in the latter part of the last century, showed that, MODES OF SOWING THE WHEAT. 53 both as regarded quantity and quality, the dibbled wheat was superior to the broadcasted ; the ears of the wheat were " indisputably larger, the grain of greater bulk, and speci- fically heavier, while the berry of the corn was more equal throughout, few small grains being mixed with it. The average quantity of seed then used being three pecks per acre, the cost of dibbling it being 6s. per acre, and the average increase of produce, as compared with broadcasting, being two bushels per acre. In one well-authenticated case the increase was eight bushels per acre, and in price Cd. a bushel better. The following description of the method adopted in the practice of the period we have al- ready alluded to, will be useful at the present time, when the dibbling system is on the increase. The wheat is generally planted upon a clover ley, and, if it be very light, it should be ploughed a week or ten days before -the dib- bling is commenced. In this light land a fall of rain will not be disadvantageous, as the soil will be so far solidified as to enable the holes to be made easily, and to be main- tained perfectly open till the seed is dropped. Where the land is heavy, the ploughing should be done only a day or two before the dibbling, and in this soil it is absolutely im- perative that the sowing should be done early in the season, as it is impossible to dibble properly in heavy land in wet weather, the dibble holes simply becoming a series of little wells, in the bottom of which the water collects and rots the grain. The land being ploughed, a man should follow the plough with a spade, and break down or level the fur- row where this may have been leffc uneven by the plough ; then a roller is to be passed over the surface. The dibbling then commences, which is carried out either by women or by men. The dibble is made of iron, 2 feet 9 inches in length, with a wood handle ; the lower part of the dibble is made of a conical form, and calculated to make, when forced into the soil up to its neck, a hole 2 inches deep. The dibbler walks backward, and after forcing the dibble into the soil, before drawing it out, or rather while in the act of drawing it out, turns it partly round ; this consoli- 54 CULTUKE OF FARM CROPS. dates the sides of the hole, and keeps it open till the seed is deposited. The holes are made in the top of the furrow, at distances 3 inches from each other. The seed grains, two or three in number, are dropped in the holes by chil- dren, who follow the dibblers, — two grains being dropped in at the early part of the season, three at the later part. After the grains are deposited, the land is bush-harrowed twice or thrice, according to the lightness of the soil, and in the same day. 39. There is no doubt that improved practice in the cul- ture of grain points to the dibbling system, or at least to thin sowing ; everything, therefore, that can tend to throw light upon the subject, and its practical bearings, is of vast im- portance. Amongst those who have paid attention to it we may name Mr. Hardy of Maldon, Essex, who has de- voted much time to its practical points, and who thus, in a paper — which we deem right to reproduce here — draws attention to what may be called good and bad practice of wheat dibbling : — " Dibbling wheat is good, provided it can be, and is, performed in a proper manner ; for, by the dropping pro- cess necessarily combined with it, the surface of the land is consolidated, and the kneading of the subsoil by horses is avoided, both being essential for the well-doing of the crop. Dropping the grains, if justice is given to the plan, is better than by any modern implements and inventions of quickness, whether it be the common drill, invented by ' Tull for his organ pipes,' or Sigma's 'modern and admi- rable planter,' both of which are good in the esteem of many. But I contend that they sow the grains too many in one place, though it may be in equal quantities, which only gives them credit thus far. It is, however, to be re- gretted, and necessary to be noticed, that this dropping is generally misapplied, and done in a confused, hurried, dis- orderly, and imperfect manner, by idle or incompetent boys and girls, placing too many or no grains at all into one hole, and even by the most industrious and careful women em- ployed to do it, the quantity in each plantation is deposited MODES OF SOWING THE WHEAT. 55 (especially in cold and windy weather) too unequally to end in the best results, varying from nil to 20 or more grains, whilst one, two, or three, would answer the purpose much better were they placed there more uniformly — even admitting the holes to be made extravagantly thick or thin, at the will or desire of the planter. I prefer the single- hand dibble, which an experienced workman can handle with great dexterity and quickness, and can occasionally plant with his left hand, in its right place, and at its pro- per depth, more precisely the number of grains his em- ployer wishes to have planted ; or, better still, by two care- ful women following the dibbler with small baskets, or measures, and a nut shell made to hold any desired num- ber of grains. This nut shell to be dipped and filled at every planting, and dropped into each hole by the right hand, as if by rule ; or it may be, by dint of practice and care, nearly as exact with the finger and thumb, and this, too, at no more expense in the end than ordinary dibbling or dropping in the slovenly and incomplete manner I have described. Children, however, could do it as well, or bet- ter, if they would, and did not the cold prevent them ; and the only way to persuade them to do it properly is by kindness of master and man, and, moreover, by rewards in money to the best competitors — for their own use. As I have so frequently endeavoured to prove rational and uni- form seeding to be better than irrational and careless thick seeding, from 1-^ to 2, 3, or even 4 or 5 bushels per acre, as is sometimes practised in Scotland, for securing the best of crops, I am particularly requested by several distin- guished agriculturists to publish a recapitulation of my views, what quantity I consider is best suited for planting an acre of land, and at what distance the holes should be dibbled to admit of from 1 to 6 or 7 grains to be deposited in each hole at the rate of 1 bushel per statue acre. I will here briefly subjoin my calculation for their guidance. . . . . There are then 160 square roods, or 4,840 yards, or 43.560 feet, or 6,272,640 square inches in a statute acre of land. There are also of small grained wheat 56 CULTURE OF FARM CROPS. about 10.000 grains in a pint, or 20,000 in a quart, or 160,000 in a peck, or 640,000 in a bushel, consequently, if it were required to be planted single grains at 1 inch apart square, it would require only 9 bushels to plant an acre. If the holes or plantations are required to be made at 6 inches apart square, about the distance practised in the ordinary way, at 1 bushel per statute acre, it will ad- mit of just 1,045,440 holes, and 6 grains for each planta- tion, provided the whole surface of the land were to be covered, with no furrows between. But as furrows are in most cases required, no seed is necessary for the?n, which reduces the number of plantations on an acre to about 897,520, viz.: — at 1 bushel per acre, 7 grains for each hole, at 6 inches apart square, or 4 plantations on every foot, which, if planted with precision, will admit of all casualties the wheat plant may be supposed to have to con- tend with from birds, rooks, pigeons, partridges, pheasants, rats, mice, slugs, wireworms, moles, hares, rabbits, and other destructives, also frosts, rains, and snow, imperfect cultivation, weeds, &c. But what of the issue when neither of these mishaps do occur, as they often do not, when planted well, with double this quantity of seed, or more 1 Some will reply, and I admit it with truth, that it would ripen earlier, and prevent its tillering too much in the spring, which causes a coarse and uneven sample. But it then certainly would only eventuate in producing a puny and root-fallen crop — a weak progeny of less than one good ear's produce from each grain sown, and not able to with- stand the ills attending it, at least in such a climate as ours, so unapt for ripening corn in very many seasons. I my- self contend that 1 grain only at a place (though I would not trust to it unless I could plant it early in September) is far preferable to more, as then that one plant can be best ensured. But it must be planted early, in order that it may tiller in autumn, and enable it to perform its natural capabilities. Thus, it would require only 10§ pints to plant an acre, — I mean, were the whole surface of the land planted at 6 inches apart square, or 4 plants on one foot. MODES OF SOWING THE WHEAT 57 I repeat it, though I do not set it down as a general rule to follow, that 1 plant will produce more than the 6, 7, 8, 9, 10, 20, or more would or could, were they allowed to be grown in any one place. I have proved it repeatedly by experiments, and others may do the same, that one plant at a place, or in one hole, will invariably produce more than any other number above it, proportion ably from 1, 2, or it may be to 50. I conclude, then, that whatever quan- tity of seed we choose to plant for securing the best of crops and sparing the seed, every grain ought to be planted separately, in order that each and ail may tell, and not be subjected to linger, fade away, fall down, or prematurely ripen. As it proves to be correct practice to do this by experiments repeatedly made on small plots of land, why, I enquire, would it not answer the purpose to do it on a broad scale ? " 40. We have yet, however, to note before leaving this department, to advert to the mode of raising a crop of wheat by transplanting. This method has had some attention directed to it of late, from the circumstance that one great difficulty attendant upon these new, or — as from what we have detailed, of old experiments — what we may call revived modes of raising crops of wheat, is the getting ready the land in time to admit of the very early sowing which thin seeding or dibbling necessitates. By planting, however, a small space in the corner of a field or in the garden, at an early period, say August or September, a number of plants may be raised to be good and vigorous when the land is ready in autumn. The following, from the " Agri- cultural Gazette," will be interesting on this point : — " A few years ago an experiment was tried at the model farm at Glasnevin, near Dublin (suggested by the one re- corded by the celebrated gardener, Miller), of transplanting wheat in the spring, parting the roots so as to make each plant into ten or more. The crop was as good as from a field sown in the usual way. It may be worth considering whether this plan might not be advantageously tried if we are to have another wet season \ for the very weather which 58 CULTURE OF FAEM CROPS. is utterly unfit for sowing is the best for planting, accord- ing to the well-known proverbial maxim, ' Set wet, and sow dry.' Some persons, not well acquainted with country affairs, might suppose the process to be much more tedious and more costly than it is. They will, perhaps, be sur- prised to hear of the payment made by many nursery gar- deners in England to the women and children employed in transplanting small forest trees (about a finger long) from the seed-bed. They pay 2d. a thousand; and many women and children are glad to earn in this way from 4d. to 6d. a-day. It is even found to answer in some parts of England to sow wheat in the way that is called ' setting ' or ' dibbling,' dropping the grains by hand into holes made for the purpose, as, indeed, is always done with beans. It would not take much more time and labour to lay the little off-sets of the wheat in a shallow furrow, and then slightly cover them over. And, as some set-oif against the expense of labour, is to be reckoned the saving of the seed wheat. But, however, the alternative is not between sowing or planting a field of wheat (the former being in such a season as this impossible), but between the planting and the leav- ing of the field absolutely waste for a whole season." 41. There is tl nothing new under the sun," and it holds good of this so-called " new " system of transplanting wheat, for perhaps the most complete record of what has been done in transplanting of wheat is to be met with in papers pub- lished eighty years ago in the Transactions of the Bath and "West of England Society, a glance at the leading features of which will here be interesting. Thus, a Mr. Bogle — the name need not be taken as ominous by our Scottish readers — states that he has known wheat transplanted in September, October, November, February, March, April, and even as late as the middle of May, all of which have answered well. And the result of what he observed in connection with the subject led him to believe that wheat is not ail annual but a perennial, provided it is eaten down by sheep or cut repeatedly by the scythe or the sickle, so as to prevent the plants coming to ear. (For a very suggestive note on this MODES OF SOWING THE WHEAT. 59 point see a recent article on Thin Seeding by the Old Norfolk Farmer in " The Journal of Agriculture," Nos. 77, 78, New Series, Blackwood.) Mr. Bogle estimated that the plants re- quired for one hundred acres could be raised on a plot of one acre. And we may here state that, planted at distances of 9 inches each way, 77,440 plants will be required for an acre. A very remarkable feature connected with the mode of trans- planting is the enormous increase we can obtain by it when we divide the original plant, giving each part to a separate whole, care being, of course, taken to have at least one rootlet to each divided part transplanted. There is a well-authen- bicated experiment carried out by a Mr. Charles Miller of Cambridge in 1769, who obtained from one single grain the enormous produce of 2 1,1 09 ears, the corn from which measured three pecks and a half, and weighed forty-seven pounds. This was obtained by the following mode : — On ihe 2d of June, 1766, the wheat, common red — was sown, and on the 8th of August a single plant was taken up. This was divided into 18 parts, and each part planted separately. These tillering well, some were taken up in •September and again divided, and the remainder were al- lowed to remain in the ground a little longer, till between that time and the middle of October the whole were taken up and divided, the result of the final division being the obtaining of sixty-seven plants. These sixty-seven plants were allowed to tiller all winter, and in spring, between the middle of March and the 12th of April, the whole were taken up and divided, till 500 plants — these plants were the final planting — which produced in the aggregate the enormous number of ears noted above — 21,109 ears. Some of the roots produced one hundred ears, and many of the ears produced measured seven inches in length, and contained between sixty and seventy grains. Wheat is — so far as our experiments have proved, and they, are corrobo- rated by those of others — by no means a difficult plant to transplant; it takes kindly to the ground, and stands even a sharp frost well. The produce of wheat transplanted in the autumn, say October, is greater than that transplanted 60 CULTURE OF FAEM CROPS. in the spring, say in March ; the result of one experiment may be represented thus, winter, 20 ; spring, 8. We have already said that in transplanting wheat it is necessary, or •considered necessary, that the plants should have tap-roots. We tried a good many plants with and without tap-roots, and so far as the readiness of the plants to take to the ground was concerned, we could not trace any difference. All we planted of both kinds took at once, and those hav- ing no tap-roots were merely white at root, and did not certainly look as if they could possibly strike, but strike they did, and soon. We mention this fact as corrobo- rative of the statement, that the wheat plant is a very easily transplanted one. 42. On the subject of thin and thick sowing a vast deal has, been written ; space does not permit us here to give even the most rapid of resumes of this, interesting as it undoubtedly is. A very excellent view of the arguments which have been made from time to time on the subject will be found in a paper in the " Journal of Agriculture," by the " Old Norfolk Farmer," entitled " On Thick and Thin. Seeding." We can here only glance at the subject. Mr. Mechi, who has for a long time been, and is still, the advocate of thin sowing, says that thin sowing should be early sowing on heavy land, this being the invariable re- sult of all thin sowing trials. The land should also be drained, subsoiled, and kept free from weeds by the hand or horse hoe, if thin sowing is to be a success. On light lands and bog lands the wheat plants are apt to be de- voured by the wire-worm, to prevent which the roller should be freely used. On reclaimed bog, a deep, rich, vegetable soil, Mr. Mechi says it is imperative to sow thinly three or four pecks to the acre, or the crop would be mostly straw. Thin sowing somewhat delays the ripen- ing of a crop, especially if sown on heavy land so late as November or December. Anything beyond 1 bushel of seed per acre has not had the effect of increasing the yield, the extra seed being so much wasted. The plants from the 1 bushel of seed, Mr. Mechi found, kept their healthy green THIN AND THICK SOWING. 61 colour throughout, never having turned yellow in spring. This, we may remark in passing, we have found to be an invariable attendant upon the plants of thin-sown wheat, a healthy greenness most refreshing to look upon. But the 2-bushel plants of Mr. Mechi turned yellow, the 3-bushel plants still yellower, and were decidedly the worst plants in the field. Mr. Mechi, in a later communication to an agricultural journal, has the following, the perusal of which will be interesting : — " It must never be forgotten that thin sowing is the parent or first cause of large and vigorous ears to select from ; on this point there can be no mistake, seeing that thick sowing has an exactly reverse effect, diminishing and crippling the growth of the ear, until, with extreme quan- tities, there is scarcely a good kernel or good ear. There- fore, in order to get good ears to select from, we must sow moderately. It would be a very dangerous experiment to sow generally so small a quantity of seed as one peck per acre. In highly cultivated, warm, mellow soils, free from weeds, and in good heart, where harvest is ready by the 1st of August, or earlier, such small quantities may be sown, provided the sowing is done early ; but we must ask ourselves how much, or rather how little, of the land of this kingdom is in the state I have described. One kernal in a hole, at intervals of 9 inches by 4, would, under favourable circumstances, be ample, and produce much more than if four times that number were sown ; but, then, we have rooks, French partridges, birds, mice, arid wiroworm to contend with. " The latter may be easily got rid of by sowing or plough- ing in rapecake, with or without salt, the latter to be com- mended. Light-land men* would be astonished to see our cold tenacious birdlime -like seed-beds in a wet seed-time, even where well drained and deeply cultivated. The seed- ing of friable manageable soils cannot be compared with such a state of things. Besides, the time of harvesting depends upon the quantity of seed sown, and the period at which it is sown. G2 CULTURE OF FARM CROPS. " It is all very well to talk of sowing in September, but in many districts this year all hands were then employed in harvesting, and in late districts seed time will probably be in November and December. On my own farm, ex- perience has taught me the danger of so small a quantity as one peck per acre, and I know of some cases this year where one peck of Mr. Hallett's wheat on one acre has been found to produce only three quarters of inferior quality per acre on land which generally produces five or six quarters. Parties who have been thus unsuccessful, should, equally with those who are successful, communi- cate their results for the information and guidance of their brother-farmers. " Absurd quantities of seed continue to be sown as a general practice ; but I would advise my brother agricul- turists to feel their way down to a proper minimum quan- tity, suited to their soil and climate, by small experiments in their fields. I see so many farms where weeds are allowed to luxuriate and perfect their seeds almost undis- turbed, in competition with the cereal crops, that in these it would be the height of folly to attempt thin sowing. There they must sow thick, to pre-occupy the ground and smother the weeds, as they will not clean-hoe. Thin sowing, to be successful, demands, like a thinned turnip crop, a frequent use of the hand and horse-hoe, to which much of the land of this kingdom is still a stranger." 43. While much has been written on the advantages of thin sowing, thick sowing, however, has not been without its advocates. It is well known that broad-casting is more in general favour in Scotland, and some districts of England, than drilling ; and it is hard to believe, as suggested by Mr. Barclay, " that so great an advantage as the sowing of a bushel and a half of seed per acre can have been over- looked for so many generations. It seems more reasonable to suppose that long practical experience has taught the farmer the more prudent course of a liberal supply of seed." Mr. Barclay, here quoted, in a communication to the Royal Agricultural Society's Journal, gives the result, in a tabular THIN AND THICK SOWING. 63 form, of some experiments on the three modes of sowing corn, dibbling, drilling, and broadcasting, which are re- markably in favour of broadcasting, and which, he says, if not conclusive against the thin sowing mode, now so much advocated, should, at all events, induce caution on the part of farmers not to depart hastily from the prac- tice of their forefathers. The experiments detailed in the table here given were conducted with great care, on level land of uniform quality, a good deep loam on chalk sub- soil ; and the crop was preceded by clover ley, folded by sheep. The land was ploughed 5 inches deep, as it was not thought desirable to bring the sheep dressing below that point. The seed was sown on the 7th of December, and the dibbled and drilled wheat was hoed in the follow- ing spring ; the broadcasted was harrowed in the spring. The plants in the thin-sown plots were by far the health- iest looking throughout the season ; but when harvest approached, the quality of straw and grain was soon shown to be inferior. The samples of the different lots were valued by an experienced miller. 64 CULTURE OF FARM CROPS. * ? to ,_ to ? II r f 2. " jjf — £. 2. |f- a s J" cT I Quantity of seed per Imp. acre.

Mr. Hallett also points out that he at first started by selecting from accidentally large ears, in the supposition that these would give a much finer produce the next year ; but he found that the quality of the grain was so bad as to be un- saleable, and this result was the invariable one of all trials in this direction. He therefore adopted a plan which we think was the most philosophical of the two — namely, selecting an ear which gave the finest quality of grain, and trusted to the power of the selecting principle to increase the size and development of the ears. Mr. Hallett chose, in the first instance, the " nursery" wheat, the finest red HALLETT'S SELECTION SYSTEM. 85 wheat known. The following is the plan of selection adopted : — The produce of a single grain is a bunch, or, as Mr. Hallett calls it, a " stool," consisting of many ears. The grains are carefully taken from each ear, and are planted in such a manner that each ear, or rather the grains which were taken from it, occupies a row separate and distinct from any other row, and the distance between each grain in the row is 12 inches. The grains from another ear are sown in another row, 12 inches from the first row, so that all the grain is deposited in 1 2-inch squares. When the ears produced from the different grains are ready, a very careful study and comparison of the stools from all these grains is made, and the finest one is selected, and accepted on the principle that the parent grain which produced that " stool " was the finest of the lot. The grains produced from each ear of this stool are again planted or sown in separate rows, as above described, for the selection of the second year, and so on each year. The result of the repeated investigations of these repeated trials has shown Mr. Hal- lett the essential importance of repeated selection, inas- much as in the grains produced from the same ear one is found greatly to excel all the others in vital power. Mr. Hallett, referring thus to these and to other circumstances, which space does not permit us to allude to here, as evi- dence that " selection " is capable of increasing the contents of the ear, proceeds to show that it is also powerful in in- creasing the number of the ears. There are no correct, or even approximately correct, data at our command showing the number of ears produced from the usual quantity of seed sown per acre, which may be set down at 7 to 8 pecks. Mr. Stephens estimates it at about the same number as there are grains in a bushel, or under 800,000, which is equal to about one ear of produce for every two grains of seed sown. Taking these data as they are, Mr. Hallett computed the numbers given in the year 1861 upon the two systems, one his own selection, and the other an or- dinary method. The two fields upon which these were tried were simply divided by a hedge. In the one in- 86 CULTURE OF FARM CROPS. stance — the old method — the number of pecks to the acre of seed sown was 6, and from this the crop was 54 bushels, consisting of, at its thickest part, 934,100 ears. On the " selection " system, the quantity of seed sown per acre was four and a half pints, the seed being sown or dibbled 1 2 inches apart each way, and the number of ears produced was 1,000,880, or 67,760 ears in excess of the other yield; thus giving this excess with a saving of twenty-one times the quantity of seed. The system of " selection " in being carried out into practice, will obviously modify that as at present adopted. The first modification is the time of planting; that this must be earlier than the present is obvious enough, inasmuch as a grain which has to occupy a large space of ground, and is expected to produce a greater number of ears, will require a longer time than if grown under ordinary circumstances. The second modifi- cation is, the necessity for apportioning the quantity of seed in proportion to the time at which it is committed to the ground. This, however, is done in ordinary practice, where the quantity of seed sown is greater in proportion as the time of sowing is later. The third modification is, the distance at which the seeds should be sown ; this may also be subjected to change, according to the time at which the sowing is done. Mr. Hallett, in giving directions upon these three points, says that he can only do so on the sup- position that he has selected seed to deal with; for the different grains of ordinary wheat are so very unequal in reproductive power, that it "would be manifestly impossible to fix on any uniform distance " or quantity. For, as re- gards distance, it is clear that if a certain space was that which was required for a vigorous grain, for a less vigorous one it would be too much. While on this point, Mr. Hallett draws attention to the fact, that by selection the reproductive power of wheat is equalized in a very remark- able degree ; and that the equalization is just in proportion to the length of tirne over which the selection has been carried; and this equalization is not confined to one, but it is observable in all the peculiarities of the plan. ARTIFICIAL FRUCTIFICATION OF WHEAT. 87 The following is the mode recommended when this sys- tem is proposed to be carried out on a small scale of a few acres, the grains being dibbled singly in holes not ex- ceeding 1^ inch deep: — Distance between the Rows.

Artificial Fructification of Wheat. — The discoverer of this mode is a Frenchman, by name M. Hooibrenck, and his theory is that, in ordinary circumstances, natural fructification of the wheat is so feebly carried on and out, that artificial fructification should be adopted where greater products are demanded. The process by which M. Hooi- brenck proposes to effect this artificial fructification is as follows ; — Across the field of wheat he stretches a cord, to which are attached pieces of wool, some of which, at inter- vals, are smeared with honey. These pieces of honey- smeared wool, being in contact with, the ears of wheat, render, or are supposed to render, the stigmas glutinous, and to favour the adhesion of the pollen to them. By the movement of the cord, the pollen, which is taken up by the pieces of wool which have no honey smeared upon them, is given out to the smeared pieces, and by them to the stigmas, coating these, so to speak, with pollen, and thus artificially impregnating them. A strict investiga- tion into the physiology of plants tends, however, to make it, we think, abundantly clear that, imposing as this theory of artificial fructification is, there is, in reality, little — we should say, rather, no^-need of it. Nature does her work sufficiently well, in this department at least, to need no help from man. Is it, indeed, in view of the fine re- lations which exist between plants that the process of fruc- 88 CULTURE OF FARM CROPS. tification is one in which man can help 1 Can any of his processes, no matter how delicately adjusted they may be, come up to that fine adaptation of means to an end which we find surrounding us in all the departments of nature1? To both of these questions it need not be considered pre- sumptuous to give a reply in the negative. The truth is, that although it may be said, in reply, that the fructifica- tion of our cereals being dependent upon chance, that chance may be lessened by some process which will secure greater certainty, nevertheless, we find, in fact, that there is produced in practice such a superabundance of pollen, that, although much is scattered fruitlessly by the winds, or dashed into uselessness by the rains of heaven, enough is left to impregnate the flowers, the quantity produced by each ear being far in excess of what the fructification really demands. Hence a large balance, to use a commercial phrase, remains to cover losses, even large as they may be, resulting from the above natural causes. But even grant- ing that it would be advisable to save the pollen, which might otherwise be lost by some artificial means, it is more than questionable whether — -indeed, an investigation into the matter will show that there is every probability that — the plan proposed by M. Hooibfenck cannot and will not be successful; for it proceeds upon the assumption — how dangerous the assumptions in the nature of scientific ques- tions are our readers well know — that the smeared wool takes up or gathers the pollen, and afterwards delivers it to the stigmas. How do we know that either of these things is done? Whatever may be said in favour of artificial fructification — as much may be said of it — of isolated examples of flowers, there is, we venture to say, so much that is practically difficult to be overcome in applying it to flowers in the mass, as those of a corn field, that it will not take a place, at least in our day, amongst those processes which can be made available by the farmer in his everyday labour^ INDEX.

DIVISION I. THE CEREALS OR GRAIN CROPS. PART II. THE DISEASES AND PRESERVATION OF WHEAT. CHAPTER FIRST. THE HABIT OF GROWTH OF THE WHEAT PLANT. 1. BEFORE proceeding to describe the diseases of wheat, it will be useful to point out the chief peculiarities con- nected with its habit of growth. These are not only in- teresting in themselves, but afford, when investigated, some valuable lessons, useful in farm practice. It will be doing those of our readers a service who have not considered the subject from this point of view, if we go somewhat into details ; and this we cannot better do than by giving a ra- pid resume of an admirable paper by Professor Buckman in the seventeenth volume of the ' Royal Agricultural So- ciety's Journal' 2. Habits of growth of wheat plants. — If we examine a grain of sound wheat, we find that the perisperm or outer husk (a a, fig. 1) covers the embryo, b c; this having at its upper part the plumate 6, from which the axis ascends, G 90 CULTUKE OF FARM CROPS. Fig. 1. which carries the leaves, and ultimately the seed; and at the lower part the radicle c, from which, on the seed ger- minating, the roots proceed. On the seed being placed in the ground under circumstances favourable to its proper germination, the radicle a, fig. 2, bursts through its integuments, and lateral rootlets begin to develop themselves to the right and left. These rootlets are but sheaths, which, at the early stages of the germination of the seed, cover the true root l>, fig. 2. These roots are elongated for a greater or less distance without sending out lateral branches or fibres; but these at last appear proceeding from slight projections on the side of the roots. These fibres, again, give rise to other lateral branchings out, and are called fibrils. These developments take place in win- Fig. 2. Fig. 3. THE PROCESS OF TILLERING. 91 ter-sown wheat — which is that we are at present examin- ing— according to the mildness and severity of the season. Little progress is made in cold weather, but in mild a few fresh rootlets will bud from near the base of the old ones, and coincident with which a bud starts from the axil of the first leaf. Where the plant is hardy, each of the early leaves may develop like a bud, and new roots will start and strike into the soil, from which to draw up the nutri- ment; so that in a short space the initiative of several heads of what will be obtained from a single seed, as shown in fig. 3, in which a a are the heads starting from the axilla of the root-leaves, these last in the diagram being turned back, so as to show the leaf-buds. We thus see that in the process of tillering — as the technical phrase for this first development of the wheat plant puts it — the two organs, roots and leaves, are developed coincidently with each other, a new bud requiring a new root to bring up its nutriment from the soil, whilst the older roots branch out into fibres and fibrils, and get further removed from the centre of growth. 3. The process of tillering does not go on under uni- formly favourable circumstances. Much depends, for in- stance, upon the thickness with which the seed is sown, and upon the mildness of the season. Upon the question of thick and thin sowing we shall have something to say in its proper place; (see Vol. on Wheat, Part First of the Cereal Crops ;) so we shall at present leave it, only now stating that, where thick sowing is practised, the plants come up thin and emaciated, and so close that there is no room for their laterally branching out. Mild weather in winter causes the condition in the wheat plant known as winter proud, in which the upward development has not been arrested ; so that its strength is given to the part above ground, weakening the tillering process, which enables the roots and fibres to be developed to their pro- per point. Where wheat is in this condition, the beneii- cial eifects of eating it down by sheep, or even cutting it by the scythe, will be easily understood. We now come CULTURE OF FARM CROPS. to examine the habit of growth of the wheat plants in the spring, which bring about a renewed action of the growth of the winter-sown wheat. Many of the older fibres die during the winter, but on the return of more genial wea- ther new buds are produced, new roots being pushed into the soil, and new fibres and fibrils are produced from these. When the central axis of the plant has by these means been developed or elongated sufficiently, tillering of the plant ceases, and the whole of its strength is devoted to supply the upper part with its leaves and stems. These latter vary, in number, according to the value of the plant, from five to twenty, and produce the ears of grain, which all ripen nearly at the same time. Such is the habit of growth of winter-sown wheat. Professor Buckman next proceeds to show the difference between it and that sown in spring. 4. Winter and Spring Wheat. — As stated in Part First, par. 3, p. 5, winter and spring wheat are not specially dis- tinct ; and that it is easy to give a winter wheat the char- acteristics of a spring one, and vice versa. Professor Buck- man gives the following table, showing the results of some experiments upon different varieties of wheat, bearing upon this point : — TABLE OF THE GROWTH OF WHEAT IN EACH MONTH OF THE YEAR. Years. Months. Height. Length of Head. Remarks. Ft. In. In. 1851. June 3 - 5 3 Clean straw. July 2 10 2 Do. do. August 4 1 4 Do. do. September October 3 11 3 10 4 4 Do. do. Rather blighted.

WINTER AND SPRING WHEAT. 93 "The winter," says Professor Buckinan, "was mild and wet. All the samples were gathered in August. The September, October, and November plots gave the best samples ; that sown in March, April, and May was by far the worst in the series. Blight both in straw and ear was most prevalent from December, though in Spring months that sown in June, July, August, and September, was clean in the straw ; but the ears of the July sample, though they ripened, were remarkably small. From this experi- ment we see, that although the wheat sown in the autumn months certainly succeeded best, yet that of the spring months gave a yield : and indeed winter varieties of wheat are often not sown until as late as the latter end of Febru- ary; and we must remember, that if winter wheat be left until the spring for sowing, it behaves in its rooting and tillering much as spring wheat, and hence the difference is merely one of growth." This difference may be described briefly : in spring the winter-sown wheat sends forth new roots and fresh librils, tillering and forming tufts, the shoots of which root precisely like the central blade : this, which may be called the second growth of the winter-sown wheat, takes place at the same period as spring-sown wheat is coming up. The growth of the spring-sown wheat be- ing so much quicker, as the time for its development and ripening is so much shorter, than that of winter-sown wheat, does not, therefore, tiller to anything like the same extent. The development of the roots and fibrils goes on regularly, having no period of rest. The difference, then, between the growth of winter and spring-sown wheat is only one of degree; nevertheless the difference is such, that it involves different treatment on the part of the far- mer. In the first place, spring wheat must be sown more thickly than winter, as each seed brings forth a much smaller — as a rule — number of ears, and the thickness of the plants in the ground modifies the effects of the droughts which may probably supervene. So far as regards the preparation of the soil — on which point we have yet much to say in its appropriate place — that for spring must be 94 CULTURE OF FARM CROPS. very carefully prepared, so as to have a deeper tilth and more uniform depth than that for winter-sown." 5. " Tkrowing-out " of the Wheat Plant, — Before dis- cussing the subject of the habit of growth, in its early stages, of the wheat plant, it will be useful to give here a resume of what Professor Buckman says on the subject of the lifting action of frost on wheat plants, commonly called throwing-out. The changes to which soils, remarkably varied as they are in texture, &c., &e., are subject under atmospheric influences, are most commonly — 1. Pulverisa- tion and expansion after frost ; 2. baking after rain ; 3. Compression when filled with moisture; 4. Cracking in drought. Some soils are so loose that heavy winds shift them along with their sustained crops; this is more espe- cially, if not wholly, the case with soils resulting from the disintegration of the more silicious bed of the new red sandstone. The evil may be remedied by giving a more tenacious stability to them, by mixing them with marl. It is a curious disposition of circumstances, that in districts where this soil is met with, stiff kuper marls of the same formation are also met with. In Worcestershire, as pointed out by Professor Buckman, the marl forms rounded knolls, from which it can be carted easily downhill to the light lands. The expansion of soils takes place very generally in "clunchy" clays, all marls having much lime and ar^ gillaceous matter in their composition, with a comparatively small proportion of sand. In soils of this nature the frost penetrates, and by expansion lifts the masses upwards in a remarkable degree. The soils in the Chalk and the Oolites are sometimes very liable to this expanding and lifting ac- tion— so much, that the wheat plants growing on them are frequently lifted out and left unplanted after the soil is rendered more solid by succeeding rains. Heavy rains get rid of this to some extent, by working the soil round and down upon the roots of the plants, and even to such an extent as to produce a skin or pellicle on the upper surface. Eolling and sheep-treading are also beneficial in such cases. But where this artificial consolidation is given to upraised "THROW ING-OUT" OF THE WHEAT PLANT. 95 soil, it is essential that, on the plants having again fairly taken to the land, hoeing and top-dressing should be done, to loosen the soil, and to expose it with its chemical ferti- lisers to the atmospheric influences, when the accelerated growth takes place. Professor Buckman points out that the best way to obviate the evils of this expansion of soils, in heavy lands, is to raise as large green crops as possible, and to plough in all the leaves. By this means a more equitable pulverisation of the soil is obtained, and by the gradual admixture of vegetable matter a loamy soil is ulti- mately produced. Farmyard dung, when in a fresh state — not decomposed and rotten — sometimes acts in increasing the expansive lifting action of soils, as the long straws act as media for conveying water into the soil, and which, becoming frozen and expanding, lifts the soil. In the stiff and argillaceous soils of the Lias and Oxford clays, the rain acts not by crumbling and lifting, but by en- larging the plastic mass of soil, so that it is compressed very tightly round the roots of the wheat plants, depriving them of their free power of growth and action. This plas- tic element in soil, as pointed out by Professor Buckman, is most injurious to wheat, from the comparative slowness with which decomposition proceeds, air and light being kept out. Coldness is also a marked characteristic of such soils, from their retentiveness of water. The remedy in such cases is thorough drainage, mixing the soil with burnt clay, dressing with town-refuse, coal ashes, &c., the use of fresh long farmyard manure, and of all other means by which the texture will be lightened, and the soil made friable and pulverised. Stiff soils are peculiarly liable to crack in dry weather, which is very injurious to the de- licately-formed roots and fibres of wheat. If, after a long continuance of dry March winds, the soi^gets cracked, the fibres are rent and the secondary growth is impeded, so that when the return of more propitious weather fills up the cracks, and restores ihe soil to its proper condition for the maintenance of growth, that growth is given for some time in repairing its condition, in place of aiding the general 96 CULTURE OF FARM CROPS. growth. Having thus described briefly the general habits of growth of the wheat plant, it will be obvious that the final and perfect development of the seed or fruit will be dependent upon the way in which their habits are aided. In the points involved in the discussion of the question as to how the productive capabilities of wheat are dependent upon the mode in which its habits of growth are consulted and assisted by the modes of culture, Mr. Hallet, in a re- cent paper in the ' Journal of the Royal Agricultural So- ciety,' has some interesting and suggestive matter. Mr. Hallet, by the term tillering, understands the " horizontal development" of the roots; by the "vertical develop- ment," the growth upwards of the leaves and stems ; and by the " natural " growth of wheat, that mode of cultiva- tion which gives free play to its nature, or by which the habits of the plant — as those we have already described — are best aided. The extent to which the "horizontal" development takes place in the growth of the wheat plant may be seen from the fact "that the stems of a single grain, having perfect freedom of growth, will, in the spring, while lying flat upon the surface, extend over a circle of 3 feet in diameter, producing at harvest from fifty to sixty ears." The vertical development is also dependent upon the way in which the horizontal development is aided or retarded. This, as Mr. Hallet points out, is abundantly shown by the fact that thin crops generally produce fine ears. For de- tails of great interest connected with the culture of wheat, the reader is referred to Part I. of the present series on the Culture of Farm Crops, chap, vi., p. 78, par. 49. CHAPTER SECOND. THE DISEASES OF WHEAT OP VEGETABLE ORIGIN RUST MILDEW SMUT, &C., &C. BURST, &C., &C. 6. Classification of Diseases. — It is impossible to over- estimate the importance of a knowledge of the diseases PARASITIC FUNGI. 97 which attack this the most important of all our farm crops or of the best known and most readily available means by which their attacks can be prevented or remedied. It is obvious enough that this department of our series carries with it many considerations of the highest value ; for it is plain enough that we may take the utmost pains to ensure cultivation of our crop, and yet lose it quickly by the ravages of disease, all the more dangerous be- cause so insidious, and the origin and progress of which are so invested with doubt and difficulty. Hence the value to the practical man of that knowledge of these dis- eases which may enable him to prevent their attacking his crop, or of lessening their evils should they unfortunately visit it. Following Professor Henslow's classification of the diseases of wheat, we shall give our notes under the two heads "diseases of vegetable," and second, "diseases of animal or insect origin." 7. Parasitic Fungi. — The diseases which attack the wheat plant, and which come under the first class, owe their origin to the attacks of parasitic fungi. A fungus is a cryptogamous or cellular plant, which grows in contact with organised matter, never drawing its nutriment directly from the soil, water, or atmosphere, like other plants; but living by imbibing from the plant or organised body in which it grows the juices which characterise it. This nourishment is drawn through the medium of the " stalk " or "stem" or "spawn" of the fungus — called, in the lan- guage of botany, its " mycelium." The fungus is totally de- void of flowers, but is propagated by what are called "spores," or sometimes "sporules;" these are generally colourless, but if possessed of colour, that is never green. Fungi, as a rule, attain no great size, and are small com- pared with cryptogamous plants, as ferns, to which they are closely allied ; many of them are, however, so wonderfully minute as to require the highest microscopic powers to make their presence manifest ; hence the obscurity under which the subject of the investigation of their habit rests ; and it so happens that it is amongst this class that those fungi CULTUKE OF FARM CROPS. are met with, which are the causes of the most com- mon of the diseases which infest the graminaceous plants. These minute plants assume different forms ; sometimes, as in the case of the fungus — which we know by the name of mould — being made up of a series of minute sacs or cells strung together by a bead-like process as in fig. 4, each of which may be separated from the other, and yet — as is sup- posed— still remain reproductive. Other fungi assume still more complicated, and in many cases very beautiful, forms, as in fig. 5, where the "sporules" or "spores" are seen ter- urinating the tips or extremities of the thread-like processes. If, then, the plants themselves are so minute as a whole, as we have already stated many of them are, some faint notion may be obtained of the extreme minuteness of the sporules by which they are propagated or multiplied. Professor Henslow mentions that Fries — one of the great- est authorities in this branch of natural history — calcu- lated that a particular fungus might contain ten million of sporules, while M. Bauer measured the spores of the species of fungus (uredo foetida) known as "bunt " or " smut balls," at 1^\)(j of an inch in diameter; so that a single grain of wheat measuring only the thousandth part of a cubic inch would contain 4,000,000 of sporules; while, then, it is hardly possible to conjecture how many sporules each spore* contains, since they are scarcely distinguishable * Professor Henslow (in his paper in the Journal of the Royal Agricultural Society) gives the following note, which may be useful PARASITIC FUNGI. 99 under very high powers of the microscope — still some idea may be formed from the above statements of the astonish- ing— nay incomprehensible — reproductive powers of the parasitic fungi which infest our farm crops. It is not to be supposed, however, that all the parasitic fungi are merely " pests," while under certain conditions they truly are so ; they nevertheless play an important and a beneficent part in the economy of nature ; for, attaching themselves to de- caying matter, they hasten its decomposition, suck up its juices, which would otherwise taint the atmosphere, and thus act as the "scavengers of nature." "Of these parasi- tic fungi, some,'' says the authority we have already quoted, " are restricted to one species of plant, some to another ; but, generally speaking, most of them are capable of living upon more than one species of the same genus; where, of course, we might expect the resemblance in all points to be very close. Some fungi confine their attacks to the seeds, others to the stem or leaves, and some even to one side only of the leaves. One of those which attack wheat lives only on the grain, another more particularly attacks the short stalk (the pedicil) on which each flower is seated, whilst three .... are restricted to the straw, chaff, and leaves, but all five live at first beneath the epidermis, and not upon it. In this respect they bear a close analogy to those parasitic animals which live within the bodies of other animals, some immediately beneath the skin, others in the intestines, and others, again, within the very sub- stance of the muscle. It is the extraordinary minuteness of the sporules of these fungi which allows of their being absorbed by the roots, and probably also through the pores of the stem and leaves of the plants; and then they are conveyed by the sap to the various parts where they are enabled to germinate, grow, and fructify. The sporules of in preventing errors of description. "The terms sporce, sporulce, sporidce, &c., have either been applied synonymously or vaguely "by different authors. The more modern practice appears to be to use sporulae, for the ultimate granules analogous to seed ; sporidia for the cases or vessels containing them ; and sporce for the additional covering which sometimes includes several sporidia. 100 CULTURE OF FARM CROPS. fungi appear to be everywhere dispersed through the at- mosphere, ready to germinate wherever they may find a dead or living subject in a condition suited to their at- tacks. Common mouldiness, for instance, which so readily forms on many substances in a moist situation, is the most familiar example of the inconceivable numbers in which the sporules of a minute fungus are everywhere diffused." We are now prepared to detail briefly the various diseases attacking wheat arising from the presence of fungi — the first of which we notice is, 8. Rust. — Of this disease — the attacks of which cause such extensive losses of the wheat crop that all the other diseases are by some considered of comparatively little mo- ment— we take, as introductory to the more practical re- marks in connection with it, the following from one of the Agricultural Reports of the Government of the United States — from the pen of Mr. Lewis Bollman of Indiana. The extract affords us some very interesting particulars re- specting the history of this terrible scourge of the wheat crop. "The oldest of our histories," says Mr. Bollman, " the Bible, frequently alludes to it as common among the Jews, and represented it as one of the punishments in- flicted on that disobedient people. They were warned that disobedience would be followed 'with blasting and with mildew;' and when thus punished, the prophet Haggai says: 'I smote you with blasting and with mildew, and with hail, in all the labours of your hands ; yet ye turned not to me, saith the Lord.' The Hebrew name for the rust, yarcoon, meaning a yellow colour caused by moisture, is indicative of the cause and appearance of the disease then as we find them now. The Grecian and Roman writers have transmitted to us like names and causes. The Greeks called it erusitee, and the Romans rubigo. Ovid, describing the rubigalia, a religious festival established by one of the earliest rulers of Rome, makes the priest say, ' If the sun fervently heats the moist stalks, then, 0 dread goddess, is the opportunity for thy dread wrath. Be mer- ciful, I pray, and withhold thy rusting hands from the RUST. 101 crops.' In all times, and among every civilized people, this disease existed, and a moist stalk heated by a hot sun is the cause of it ; hence heavy dews, precipitated by clear, cool nights, succeeded by a hot sun during the day, soon develop the disease now as it did in the most ancient periods. It was not until the microscope was invented that the true nature of the disease was known. There is a species of plant which lives on the sap of other plants, called parasite. The rust and smut are plants of this character. The microscope shows the fact that rust is a perfectly formed plant, having roots, stems, and branches, and producing seed too small for the unaided eye to dis- cover. These exist in innumerable quantities in the at- mosphere, awaiting the condition essential to their germi- nation and development. What these are we have already seen. In the language of Ovid, they are the sun fervently beating on the moistened stalks. When this moisture proceeds from showery weather, no danger need be appre- hended; but when from dews precipitated by cool nights, then the rust rapidly develops itself Whether the mois- ture in drying so rapidly causes a contraction of the outer portion of the stem so as to induce splitting, or whether the coolness of the night causes it, is not certainly ascer- tained. Be this as it may, the result is the same — an im- perceptible splitting of the straw through which the sap oozes out. The invisible and multitudinous seeds of the rust attach themselves to this sap, and burying themselves in it, rapidly vegetate, striking their roots in the openings of the straw, thus diverting to themselves the sap of the plant, which should go to the filling out and ripening of the grain. Hence it so rapidly shrivels, and often becomes worthless. "What is the remedy against this evil? The Romans sacrificed a red bitch on the altar of the goddess Eubigo, the priest entreating her to withhold her rusting hands. If the farmers could be persuaded to sacrifice all bitches to the goddess, then an altar ought to be erected to her on every farm, for the indirect benefit to the wheat crop by increased 102 CULTURE OF FARM CROPS. sheep husbandry would more than compensate all losses from the rust. " The Jewish prophets regarded the blasting and mildew as a punishment for the sins of the people. When a peo - pie by rebellion, under such high condition of prosperity as exhibited by the census of 1860, seeks its own and the destruction of others, and the overthrow of the best govern- ment the world has seen, blasting and mildew of the wheat crop will not stay their impious hands. But, regarding the remedy for rust, through the microscope, we find that it is not in all stages of the growth of the plant that the straw is liable to split under heavy dews and a hot sun. It is not in its growing state, but in its ripening stage only, that this result is produced. Hence, whatever rapidly shortens the ripening stage lessens the danger. For this purpose there is nothing equal to stable manure, the pre- cise effects of which on the soil and on the wheat crop will be stated under the head of manures. Another remedy is in immediate harvesting when the crop is affected by the rust. The following instructive experiments on this point I find in Mr. Klippart's essay on wheat. Mr. George D. Hendricks, of Preble County, Ohio, writes Mr. Klippart as follows: — 'In 1842 I had a large field seriously affected by rust, and, having read in the Genesee Farmer the ne- cessity of early cutting, I put a hand cradle to work and left ; was absent a few days, and, on my return, found my hand had only cut a few dozen of sheaves, avowing that it was so green that he knew it would be worthless. I then procured hands and had the field cut, but too late for more than half a crop, whilst the portion cut at first was plump, and had well-filled grains.' " The 'rust,' 'red-ray,' 'red-gum' or 'red- robin' — for by all these names is it known, although the first is the most general — is the result of the attacks of a fungus known as the uredo rubigo. It forms yellow or orange-coloured blotches or powder spots upon the stem, the leaves, and the chaff; and so common is it sometimes that a whole field of wheat will have quite a red tinge given to it. The MILDEW. 103 Fig. 6. colour is different from the patches of bunt or smut fungus, being, as above stated, yellow or orange, or rather varying from orange-yellow to brown. In fig. 6 we give a sketch of the sporules. Professor Henslow states, with reference to rust, " that he believes agriculturists have confounded under this name, or the names we have above given, the attacks of what systematic botanists have distinguished as two distinct species of fungi — one of these we have named above is the uredo rubigo, the other is named uredo linearis" Of these two spe- cies the Professor conjectures that whilst the spore of the uredo rubigo undergoes no change, that of the uredo line- aris is merely " the young state of a distinct form of spore which, when further advanced, is called puccinm graminis." 9. Mildew. — This last fungus, mentioned in preceding par., is that which, according to Professor Henslow, pro- duces the disease called the " mildew." The name pucci- nia is given from a Greek word signifying thickly ; and so called from the thick masses which infest the plants. The common appearance of the straw of wheat attacked by mil- dew is represented in fig. 7. The ripe spores are of an Fig. 7. Fig. 8. 104 CULTURE OF FARM CROPS. intensely black colour, they are club-shaped at the head, as at b in fig. 8, divided into two chambers as shown, each of which contains a number of sporules. These club- shaped heads spring from tapered stalks. The patches on the straw or leaves, as in fig. 7, are composed of an immense number of these spores — in such profusion, indeed, that they sometimes burst through the epidermis of the stem and leaves, "that the whole plant appears as if it had been scorched." In fig. 8 a a represents part of the straw. The Eev. Mr. Sidney, in an able paper in the Eoyal Agricultural Society's Journal, on the " Parasitic Fungi of the British Farm " (to which we are indebted for the basis of our illustrations), draws attention to the importance of not confounding the true mildew, which we have described and illustrated above, with " another black fungus which gives a dingy aspect to whole fields towards harvest, and is often called mildew; but which never attacks a plant till it is previously diseased, and which, for want of any other name, I am obliged to announce by its botanical name, cladiosphorum herbarum" In fig. 9 we give an illustra- tion of its appearance in the straw, and in fig. 1 0 an illus- tration of the sporules ; from which the difference between this and the real mildew will be at once seen. 10. Smut. — Like all the parasitic fungi attacking wheat, Fig. 9. Fig. 10. THE BUNT FUNGUS. 105 the fungi producing the disease so called above, appear on the plant in the form of masses of dust. The botanical name for the fungi now under notice is uredines (from the Latin word uro, I burn, from the scorched appearance they give to the plants which they attack). The "smut" is formed of the spores of an uredo called the uredo segetum. This sooty powder resulting from the attacks of this fungus appears on the flowering parts of the plant; the pedicels or little stalks, on which the flowers are seated, swell, become very fleshy in appearance, and become ultimately filled with black dust. The smut fungus is often confounded with the bunt fungus (next to be noticed) ; but although resembling it in the colour and shape of the deposits of ' dust, these deposits are not half so large, while they have none of the disgusting odour which distinguishes the bunt fungi or dust. The smut fungi are not so much dreaded by the farmer as the bunt fungi, inasmuch as the spores have generally dispersed before the corn is cut, while they impart no disagreeable odour to the flour which may be made from the com infected by them. The smut or dust brand is comparatively rare in the wheat crop, common, however, in the barley, more so in the oat, and not met with in the rye crop. 11. The "bunt" or "pepper brand" fungus is much more dreaded than the smut. The botanical name for it is uredo fcetida, so called from the peculiarly disgusting odour it imparts to the infected grain. When an &' • infected grain is crushed, in place of flour, a black, oily, and foetid mass is exuded, the interior of the ovary is entirely destroyed, the only part remaining being the integument or outer skin, which serves as a case or sac to contain the spores, which amount, as we have already observed, to the enormous number of four million in one grain. Fig. 11 shows the sporules of the bunt fungus on their mycelium, their diameter being about the six hundredth part of an inch. 106 CULTURE OF FARM CROPS. 12. Causes of the Attacks of Must, Mildew, fyc. — As already noticed, Professor Henslow is inclined to believe that both rust and mildew proceed from the same fungus (uredo linearis) " under different forms or states of fructification." The Professor states that he has observed the mildew fungus (puccinia graminis) mixed with the rust fungus (uredo rubigo) in a way which strength- ens his opinion j further observations are, however, required to decide the point. A popular notion connected with the blight of wheat by mildew is that " the berberry bush (ber- beris vulgaris) is in some way or other frequently connected with" its production. This opinion is, however, founded apparently upon conjectural notions, or upon carelessly made observations ; and requires to be put to the test of a rigid examination and experiment before it can be re- ceived as correct. Although ergot is generally supposed to be a disease which attacks rye, still, as Professor Henslow remarks, a close investigation of the wheat crop will proba- bly result in proving that it is more frequently to be met with than is supposed ; the Professor suggests that should the ergot even prove abundant in a wheat crop, it will be worth while to pick the diseased grains out from the rest of the sample, not only for the purpose of purifying the remain- der, but for sale ; the ergot being a peculiarly valuble me- dicine in competent hands, although it is, when partaken of in flour, highly dangerous. Professor H. Y. Hind, of Trinity College, Toronto, has made very elaborate investi- gations in the diseases which attack wheat of the class now under description. The result of these he has given in a report to the Canadian Government. The points involved are of such importance that we here re-pro- duce the major portion of the Professor's remarks on the subject: — "Ammonia, we know, exists in the atmo- sphere, probably to the extent of one part in ten mil- lion parts on the average. At times the quantity of am- monia present is much greater than the above ratio, at other periods less. Eain water contains on an average nearly one part of ammonia to the million, and of nitric CAUSES OF THE ATTACKS OF EUST, &c. 107 acid about five parts to the million. Dew always contains ammonia, and mists have prevailed so rich in this sub- stance that the water had an alkaline reaction. Barral analysed the water collected in the rain-gauge of the Ob- servatory at Paris. He found that in one year 1074 Ibs. of ammonia fell with the rain, and 10 '7 Ibs. of nitric acid. In July he found the amount of the ammonia to be the greatest ; in September the amount of nitric acid to be the greatest. The ammonia was least in March, and increased gradually to July. In August it diminished suddenly, and continued to diminish until October, attaining its second maximum in February. These observations, although very interesting, are not satisfactory, because they were made in the neighbourhood of a great city. Hence we find that Boussingault discovered much less ammonia in the air far away from towns — a gallon of rain water con- taining only one twenty-fifth of a grain of ammonia. As a general fact, however, the water collected during fogs was extraordinarily rich in ammonia, containing on an average one-third of a grain to the gallon ; but an instance has been known — before referred to — of a gallon of water from a fog containing not less than four grains of ammonia. The constant presence of this substance in the atmosphere is not only now fully established, but its influence upon vegetable growth in this gaseous form is of the highest in- terest, and possibly of the highest importance. The ex- periments of M. Ville upon the effects of ammonia in air upon vegetation, show how rapidly and remarkably its in- fluence is felt. If ammonia be artificially introduced into air in the same proportional average as carbonic acid is found to be constantly present, namely, about one part in 2,500 parts of air, its influence soon shows itself upon the leaves, which continually acquire a deeper and deeper tint. The presence of such ammoniacal vapours not only stimu- lates the vegetation, but changes the growth of the plant, and causes the development and enlargement of particular organs. In prosecuting a series of experiments on the phenomena of vegetation, with a view to ascertain whether 108 CULTURE OF FARM CROPS. nitrogen was directly absorbed from the atmosphere and assimilated, M. Boussingault observed the growth of min- ute green cryptogamia on the outside of the flower pots which had been exposed to the air, but he failed to detect any vegetable growth on those from which fresh air had been carefully excluded. The sudden growth of varieties of fungi during misty weather has often been noticed, and their appearance may be accelerated by the introduc- tion of a small quantity of vapour of ammonia into any confined space where they are observed. I am not aware that any extensive experiments have been made upon the growth of fungi in an atmosphere rich in ammonia, such as certain fogs. I have, however, remarked with surprise their absence in an atmosphere from which ammoniacal va- pours were probably abstracted by powdered charcoal, with- out, however, drawing any conclusion from the observation, until attracted by the curious discovery of M. Boussingault, that fogs are eminently rich in ammonia. The presence of a large quantity of this plant food in certain fogs is not difficult to account for. Not only does the gradually in- creasing quantity of aqueous vapour in the atmosphere be- fore the positive appearance of mist in any locality, collect and condense rare and widely-diffused ammoniacal vapours, but the exhalations from the soil, produced by decompos- ing vegetable matter, are arrested and accumulate. The period of the year when fogs rich in ammonia may be ex- pected depends naturally upon the frequency of the fall of rain — upon the moisture of the atmosphere, and upon the winds. In Canada it appears reasonable to sup- pose that we may expect to find fogs rich in ammonia during the hot months of July and August, when the rain-fall is not so great as in September. During these months mists frequently hang over the fields, particularly in low situations. The exhalations of vapour of water from the leaves of plants being then checked, and their juices partially stagnating in an atmosphere often rich in ammoniacal vapours, all the conditions for the appearance of the fungus called "rust " on the stems and leaves of the CAUSES OF THE ATTACKS OF RUST, &c. 109 cereals appear to be fulfilled. It is commonly remarked that rust is most prevalent on new land; this is perhaps explained by the large amount of vegetable matter thrown into a state of decomposition by excess of air and the con- sequent production of ammonia. There is no doubt that much of the ammonia thus generated would combine with vegetable acids, and be fixed by clay, &c. ; but some por- tion could not fail to combine with carbonic acid, and es- cape into the air in the form of the volatile carbonate, as is observed to a great degree on manure heaps even where gypsum or other solid fixers of ammonia are employed to avoid it. We must regard new land as a storehouse of ammonia and other plant food which become liable to volatilize when liberated by too free an exposure to air without proper precautions. If the supposition be correct that "rust" is mainly occasioned by the con- currence of mists or fogs in July or August, rich in ammonia, stimulating the growth of the sporules in the stagnated juices of the plants, and that the active agent in inducing the sudden appearance of that destructive para- site is really ammoniacal vapours, we have a remedy at hand which promises, when properly and carefully applied, if not entirely to check, at least so far to arrest the growth of the parasite as to claim a general trial, especially as its effects would probably prove equally availing in arresting mildew. What we require is an available absorbent of ammonia and its volatile compounds; not an absorbent which will destroy this valuable plant food, but one which possesses the property of inducing it to assume another form, perhaps equally available as a fertilizer, although of much slower action. Eecent observations show that pow- dered charcoal answers these requirements. Charcoal not only absorbs ammonia to an immense extent, but it also oxidises it to nitric acid, and thus renders it temporarily inert, but not unavailable to future fertilization. Powdered charcoal is distributed with the utmost ease over large areas. Being an extremely light substance, and easily re- duced to a fine state of division, the least breath of air is 110 CULTURE OF FARM CROPS. sufficient to carry it for hundreds of yards. Any one who tries the experiment of gently shaking a muslin bag contain- ing coarsely powdered charcoal, in a gentle wind, will find that the operation of sowing, as we may technically express it, a ten acre field would certainly not cost one-tenth part of the labour of sowing the same field with plaster ; and as that operation is not unfrequent in this country, a prac- tical guide is at once furnished of the amount of labour the operation involves. Powdered charcoal thus sown is very uniformly distributed by the least motion of air, and its effects are marvellous. In a stable, for example, strongly smelling of ammonia from fermenting urine, ari ounce of powdered charcoal, shaken by means of a muslin bag or any fine net work, rapidly and uniformly distributes itself, and instantly absorbs the ammoniacal vapours. A curious instance of the action of this deoderizer occurred at Bala- clava during the heat of summer, when the stench was al- most intolerable in that painfully celebrated harbour. A ship-load of charcoal arrived packed in bags, and the men who were engaged in transferring the cargo to the shore were covered with the dust, as was every object in the neighbourhood — the stench which before prevailed sud- denly and completely disappeared. Nothing is more simple than the manufacture of charcoal. A few billets of wood are to be piled like cordwood, then well covered with sods, with the exception of two orifices, one to admit a little lire, and the other to allow the smoke to escape, until the heap has well taken, and then to be firmly closed for the purpose of allowing slow combustion to go on in the ab- sence of air. When cool, the charcoal may be crushed in a stout canvas bag by a lever, not by blows, and when sifted, furnishes the required material for sowing. If we ^assume with Fresinius that the quantity of ammonia in the at- mosphere amounts to less than one ten-millionth, the amount it would contain would exceed 50,000,000 tons, while that of the carbonic acid in the atmosphere is 3,300,000,000,000 tons, the weight of the air itself being 5,050,000,000,000,000 tons or five thousand and fifty CAUSES OF THE ATTACKS OF RUST, &c. Ill billions. The connection of rust with ammonia is exempli- fied in many different ways. We often find, for instance, that richly manured fields are liable to rust ; and where isolated patches of manure or dropping of cattle occur in a field of wheat, the grain growing on those patches will be rusted generally, but not always. Charcoal beds have long been considered "rust proof" in the United States. Liquid manure, when applied to crops, has proved very beneficial in enabling them to escape rust, while neighbouring crops, manured in the ordinary way with solid farm-yard manure, were much affected. In one case the ammonia would be all absorbed, in the other case part would return to the at- mosphere. Damp situations, fogs, and the season of the year when the decomposition of vegetable matter is most active, and therefore the atmosphere often charged with ammonia, are all conducive to the propagation and develop- ment of this fungus. Rust does not appear to be found on those parts of the wheat plant which are not exposed to air and light, such as the roots and those portions of the stem enclosed in the sheath of the leaves. This arises from the simple circumstance that there exist no stomata in those parts which are not exposed to light, hence a spe- cies of negative evidence that a large proportion of the sporules of rust enter the stomata directly from the air, and vegetate there. Fries states that the sporules of certain fungus are so inconceivably minute that they rise like thin smoke into the air by evaporation, and are dispersed in innumerable ways. He calculated that in one individual fungus the number of seeds exceeded ten millions ; and Mr. John J. Thomas of Wayne county, JSTew York, has esti- mated the number of plants of rust on a single wheat stalk to be twenty millions." As affording what may probably be considered a corroboration of the Professor's views — above detailed — as to the cause of rust, we may note that in our experience dibbled wheat in which the plants have been widely separated, and as a consequence more than usually exposed to the free play of the atmosphere, has always been very much rusted. 112 CULTURE OF FARM CROPS. 13. Remedies for the Fungoid Diseases of Wheat already described — To some extent in the last paragraph, taking up Professor Hind's view of the cause of rust, some of the remedies have been indicated ; and the reader in- terested in other modes will find those usually adopted in practice described in Part I., WHEAT, of this present series, beginning at par. 10., p. 23. Some sanguine cultivators believe that it is possible, by care, to exterminate the fungi which produce bunt and smut in wheat, but that this hope is not well founded is evident enough when we remember that it is not the wheat alone which is infected with them, but the grasses which grow in our pastures, and moreover — which is worse — in those which nourish at our roadside. The sources then of a supply of sporules being so numerous, it seems as if the farmer was driven to one point only, care in the selection of the seed ; and with reference to this point Professor Henslow throws out what we conceive to be a most important sug- gestion, namely, the setting aside some portion of his land for the careful cultivation of seed wheat. There may be, he says, some practical reason which forbids this being done ; but it seems nevertheless to him that it would be " always worth while for every farmer to set aside some portion of ground to be more carefully tended than the rest for the purpose of securing good and perfectly clean seed. Among other reasons for such a practice, he would then be able to weed his crop from every plant infected with bunt or smut, before the fungi ripened." When we consider how small a space of ground would be required to raise seed sufficient for a large breadth of the wheat crop, it is difficult to see why objections could be made to this very common-sense plan. True, the careful cleaning of this plot, and the not less careful weeding out of infected grains, would be troublesome ; but if the trouble which the plan would involve is all the objection that can be raised to it, why then no more need be said. We nevertheless believe that a large proportion of the success which we wish to believe yet remains for the future of agriculture, lies in the REMEDIES FOR FUNGOID DISEASES OF WHEAT. 113 direction of great care in those minute details preliminary to the larger, and as we now consider them, the more im- portant operations of the farm. It seems to be but stat- ing a truism when we say that the labour of cultivation is altogether lost if we use seed which cannot fructify ; and in great measure lost if we use seed which must produce bad crops. We would think little of the engineer who would make a steam engine of the highest finish in detail and calculated to give out the maximum of work, and then attempted to work it by burning in its furnace half coal or half shale, or shale altogether — and yet, in some de- gree, many farmers do the same in elaborately working land to prepare it for producing large crops, and then putting in seed which cannot possibly yield them. If then the care- ful raising of good seed is objected to, it behoves the farmer to see that such seed as he has at command is really free from the fungi spores. This he can secure, if he likes, by dressing, and this operation should never be omitted. It would be doing the cause of agriculture good service if a series of elaborate and carefully conducted experiments were made having reference to the employment of various dressings for wheat. Professor Henslow suggests the fol- lowing as the "kind of experiments that may be called for :" — In the first place, it will be necessary to collect a parcel of thoroughly bunted or smutted wheat seed, dividing this into a number of small packets, each containing the same weight or the same number of grains. In washing or steep- ing the contents of any one of these packets, which should be numbered as No. 1, No. 2, &c., the grains which float should be kept apart, and the fungi which come to the top should also be collected and placed in a packet and marked as F 1 (fungi from No. 1), F 2 (fungi from No. 2), &c. The fol- lowing washes or dressings may be used. No. 1. Seeds unwashed to serve as a comparative experiment. No. 2. Washed in cold water only. No. 3. ,, ,, scalding watei'. No. 4. ,, ,, water with lime, the proportions to be specified. No. 5. ,, ,, in water and brine in the following proportions. 114 CULTURE OF FARM CROPS. (a) 2 parts of water to 1 part of saturated* brine. (b) 1 part of water to 1 of saturated brine. (c) 1 part of water to 2 of ,, ,, (d) Saturated brine. No. 6. Washed in sulphate of copper. No. 7. Sprinkled but not washed with brine, — to which may be added, No. 8. Washed with stale urine. No. 9. „ „ fresh ,, No. 10. Washed in chloride of lime and water. Under which head the subdivisions (a) (b) (c) and (d) No. 5, may be used. These also may be used with the sulphate of copper, No. 6 — in order to test the utility of different strengths of the mixture. Another set of experiments should next be made by se- lecting perfectly clean grains, and infecting them by rub- bing them over with the fungi, obtained from the washing of the different packets of .diseased seeds as above described. This will be class No. 11. Rubbed grains with fungus of (a) packet F 1. (b) packet F 2. (c) packet F 3. (d) packet F 4. Infected seeds should then be washed in pure water to obtain the fungi which will float ; these being put up in packets and numbered. Pure or clean seeds should then be washed in various dressings as below, and then rubbed over with the fungi, as, No. 12. Seeds steeped in lime and rubbed with fungus of packet No. 2. No. 13. Seeds steeped in brine and rubbed ,, ,, No. 14. Seeds steeped in sulphate of copper ,, ,, The whole of the dressings given in Nos. 1 to 9 may be thus used. The experiments last named may be repeated by washing the seeds — steeped and rubbed as there described — in pure water, in order to remove any of the mixture that may adhere to the surface. Such, some- what differently stated, is an outline of the experiments * By saturated brine is meant brine made by dissolving salt in water till the point is reached at which the water will dissolve no more salt— this point is called the "point of saturation." REMEDIES FOR FUNGOID DISEASES OF WHEAT. 115 suggested by Professor Henslow, and, on the mode of fur- ther conducting them, we beg to suggest the following. The seeds thus obtained should then be finally packed, and with each packet a note given of the process under which it has been placed ; or simply marked with the number of the experiment, as " No. 9," which will indicate that it has been washed with stale urine. Different plots of ground should then be laid out, one plot allotted to the seeds of one packet. A slight sketch-map being taken of the whole as arranged. Plot No. 1. Packet No. 1. dressed as in No. 4. No. 2. Packet No. 2. as in No. 1. No. 3. Packet No. 3. as in No. 2. No. 4. Packet No. 4. dressed as in No. 9. No. 5. Packet No. 5. dressed as in No. 3. No. 6. Packet No. 6. as in No. 5. It will be necessary to have the plots separated a con- siderable distance from each other, at least three feet. And comparative observation as to the conduct — so to speak — of the contents of each plot will be more easily made if the seeds are dibbled at distances of 9 or 12 inches each way. A register should be kept of each plot, the produce of each, the time when the disease — if any — ap- pears, and the number of diseased grains obtained from each. The produce at harvesting of each plot should be carefully kept separate in packets and labelled for further experiments or examination. All this will be troublesome doubtless; but having conducted a large number of experi- ments— bearing upon different points — in this careful way, we can, from our own experience, promise those who may conduct similar ones to those we have indicated, a large amount of positive pleasure in carrying them out. It is difficult, indeed, to give one any idea of the interest which 116 CULTURE OF FARM CROPS. the plots excite in one. From the moment the seeds appear above ground the interest increases daily; and it will be strange indeed if the experimenter does not find himself making numerous and oft -repeated visits to the plots to watch and record the progress of the plants which they bear. We have little to say of the measures to be taken, or which can be taken, to prevent the ravages of the rust fungus (uredo rubigo and uredo linearis) and the mildew fungus (puccinia graminis). The spores of these fungi do not — it is understood — enter the plants which they infect by the roots, but by the more minute pores in the stems and leaves which botanists call stomata. The point is, however, doubtful ; but as the " fungi at first make their appearance in little cavities seated immediately beneath these pores, it certainly looks very much as if the sporules entered there. The stomata are naturally exhaling organs, continually discharging, under the influence of light, a large proportion of the water which they imbibe by the root. But in moist weather the function is impeded, if in some cases it J)e not actually reversed, when it would be easy for the sporules to enter these invisible stomata with the moisture imbibed by them." Excessive manuring, and especially manuring directly for the wheat, is pretty well understood to be the cause of mildew and rust ; and Mr. Knight states distinctly that mildew is induced by foggy weather. Hence the benefit of the practice followed by some of growing early varieties so as to have the crops off the ground before the autumnal fogs set in. It is also fairly established that wheat grown in light soils is more liable to mildew than wheat grown in heavy soils; and that spring wheats are less liable to the attacks than winter wheat. " Amongst the antidotes to mildew," says the Eev. E. Sidney, " I ven- ture to name clean farming, amendment of the texture of the soil, ventilation and letting in light, checking over- luxuriance in the young plants, growing early varieties in places subject to it, and avoiding putting on manure di- rectly before wheat, and howing the wheat when young." In a word, whatever tends to make the plants become sickly DISEASES OF WHEAT CAUSED BY INSECTS. 117 — as " excess of heat or cold, drought or wet, sudden changes of temperature, poverty of soil, over-manuring, shade, &c. — tends also to the liability of the crop to be attacked by rust and mildew. CHAPTER THIRD. DISEASES OF WHEAT CAUSED BY THE ATTACKS OP INSECTS. 1 4. Peculiarities of Insect Life. — Before describing the particular insect pests of the wheat crop, it will be useful, as well as interesting, to glance very briefly at some of the peculiarities of insect life. The science of entomology has only of late years been cultivated with a marked de- gree of success ; previous to this development of interest in it, it was considered by men of science as a department of natural history beneath their notice. It is now, how- ever, recognised as a science bearing with it many impor- tant interests, more especially of those connected with the arts of agriculture and horticulture. An insect, has been de- fined as " an animal with a vertebra, six-footed, with a dis- tinct head furnished by two antennae — a pair of confined immovable eyes — breathing through openings leading to internal air-tubes or trachece — sexes distinct — adult state at- tained through a series of changes called "metamorphosis." What these changes are, or of what this metamorphosis consists, we now explain. The first condition is the "egg ; " from this is produced the second change, the "larva" — po- pularly known as a caterpillar; — from the larva the "pupa," or chrysalis, is produced, and from the pupa the " imago," or perfect insect. In fig. 12 we illustrate the "larva" or caterpillar condition ; in fig. 1 3 the pupa or chrysalis ; in fig. 14 the imago or perfect insect, as the "wheat midge." Of the various orders into which insects are divided we have not space here to enter; nor is it necessary for the purposes of our treatise. Suffice it here to allude to those 118 CULTURE OF FARM CROPS. Fig. 12. Fig. 13. Fig. 14. classes having a special interest to agriculturists. The order Coleoptera — a name compounded of two Greek words which signify a sheathed winged insect — comprises all the varieties of beetles. The beetles are furnished with four wings, two of which are used for flying, which are transpa- rent and membraneous, as illustrated in fig. 15. — the other DISEASES OF WHEAT CAUSED BY INSECTS. 119 Fig 15. two wings are hard and horny, and are used to protect the flying wings. The order in- cludes a great number of tribes, some of which — as the snout beetles — are so numerous that no fewer than 80,000 different kinds belong to it. They are all eminently destructive of farm and garden produce, to wit, the corn weevil, (calandra granaria). To the order Diptera — which name indicates the chief characteristic of the insects belonging to it — "two winged" — belongs several insects, the attacks of which form the principal plague of the wheat crop — namely, the "wheat midge " (cecidomyia tritici), and the " hessian fly" (cecidomyia destructor). The character- istics of this order of insects are wings — one illustrated in fig. 1 6 — two in number, which lie horizontally. The head is hemispherical, the antennas very long, generally as long as the body, the legs long. To the order Lepidop- tera (scale winged) belong the vast number of moths, but- terflies, the larvae of which are nearly all eminently de- Fig. 16. Fig. 17. 120 CULTURE OF FARM CROPS. stractive of garden and farm produce. We illustrate in tig. 1 7 a wing of an insect of this order. The larvse of the coleopterous insects or beetles are popularly described or known as grubs — the larvse of the lepidopterous insects, or butterflies, moths, &c., as caterpillars — and those of the dipterous insects, maggots. Having thus explained very briefly the chief characteristics of insect life, we now pro- ceed to describe the various insect parts of the wheat crop, beginning with, 15. "Ear-cockle" "pepper corn," or "purples" by all of which names this is known. The grains of wheat infected with this disease become of a dark green colour, which ultimately changes to one nearly black; they lose their usual oblong rounded shape, and become nearly spherical like a small peppercorn — hence one of the names of the dis- ease ; the husks or chaff spread open ; the awns are twisted ; so that infected ears are easily observable. On crushing the grains thus diseased they are found to contain no flour but a moist cottony substance, which, under the microscope, and when moistened with water, is discovered to be a moving mass of exceedingly minute eel-shaped animalculae, and to which the name is given of vibrio tritici. The disease occasioned by the attacks of this animalcule is stated to be very injurious to the grain; but it is by no means com- monly met with, or perhaps, to state the matter more cor- rectly, it is not commonly suspected. On grinding the cot- tony mass of animalculae it is said they remain behind with the bran and not to pass through with the flour. " When a small grain of wheat is seen by the side of one infected with the vibrio, the young plant which springs from the former is not infected before March ; but then the animal- cules begin to find their way from the blighted grain into the earth, and thence into the young corn. They gra- dually ascend within the stem till they reach the ovule (or young state of the seed) in the flower-bud even before the ear has shown itself." A remarkable peculiarity connected with this animalcule is its vitality, which they will retain for six or seven years. Even if kept till they are reduced EAR-COCKLE. 121 to a state so dry that they are easily powdered, yet if mois- tened with water they will at once revive. It is difficult to estimate the numbers which a grain of wheat may con- tain ; but when in the young state fifty thousand might be accommodated in the space. When full grown the vibrio is monstrous in size compared with its condition while young and in the grain. The remedy for this disease does not lie in merely immersing the seed in water, for al- though they float at first, still they soon sink so that they cannot be separated. By subjecting them to scalding hot water, Professor Henslow has noticed that the vibrio are killed, and suggests '* the possibility of exposing infected examples to a temperature that might be sufficiently high to kill these animalcules, without being so hot as to de- stroy the germinating powers of the corn." 1 6. The " wheat midge " (see fig. 1 4), is not by some consi- dered an enemy of the crop worth troubling themselves about -, others, however, who deem that a loss of one- twentieth of a crop — which has been known to be occa- sioned by it — is a loss worth considering, have paid atten- tion to its habits and the means of preventing its attacks. The "wheat midge" or fly, of which the name is " Cecidomyia Tritici" may be seen collected in large numbers or clouds in the month of June, between the hours of seven and nine in the evening, hovering over and seeking places in the wheat in which to deposit their eggs. These eggs de- posited within the blossoms produce caterpillars, the larvae of the midge, and which feed, their heads immersed in the stigmata, according to the most plausible theory, upon the juices which are secreted by the ovary, thus obstructing its growth, and this whether it has been fertilised or not. According to others, the caterpillars feed upon the pollen after it has been shed by the anthers, thus preventing the fertilization of the young seeds. Whatever be the food the caterpillars feed upon, certain it is that their ravages effec- tually prevent all fruitful development of the ovary, and all advancement of the grain " beyond the state in which it appears at the time the flower first expands." i 122 CULTURE OF FARM CROPS. The length of the caterpillar is about one-twelfth of an inch ; it has no legs ; the colour is a citron yellow. When, about to pass into the chrysalis or pupa condition, it spins itself a fine transparent web, and which is attached to a sound grain or to the inside of one of the scales of the chaff. Seeing, as Professor Henslow suggestively remarks, that " there is a strange economy in the insect tribe, by which particular species in certain seasons favourable to their production are enormously multiplied," it does seem worth the attention of farmers to consider how best the increase of the wheat midge may be prevented. As the chrysalides of this insect remain attached to the chaff scales during the winter, it appears at first sight the best plan to burn the chaff ; or to scald it for food after the grain has been thrashed out. But it appears that in some cases the cat- erpillars drop from the chaff scales to the ground before the crop is removed, and burying themselves in the soil, are, it is presumed, changed to chrysalides, and remain buried till they are finally changed into the midge. In this latter case,. one authority presumes that the caterpillars must have been ichneumonized before they could have their habits so changed. By this term is meant that the caterpillars have been attacked by one of the tribe of in- sects called ichneumons, which lay their eggs in the bodies of other insects, usually while these latter are in the cater- pillar state. The eggs being hatched in this strange re- ceptacle produce caterpillars which devour the non-vital parts of their living conveyance, which thus dies, or is passed, before it is finally destroyed, into the chrysalis stage. The caterpillar of the ichneumon also passes to the chry- salis state, and which remains in the body of its victim, or issues out of it before passing to the chrysalis state. The caterpillar of the wheat midge has " certainly one, and pro- bably not less than three distinct species of these ichneu- mons appointed to keep it in check." The most active of these — the Platygaster Tritici, ichneumon flies or midges — a black four-winged insect with a sharp-pointed tail — may be seen in the months of July and August flying THE WHEAT-MIDGE. 123 about the ears of wheat, for the purpose of finding the caterpillar of the wheat midge in which to deposit their eggs — which, with a marvellous instinct on the part of the ichneumon fly, are adjusted in number nicely pro- portioned to the size of the caterpillar; so that just as many ichneumon caterpillars will be produced as the size of the wheat-midge caterpillar is calculated to maintain. By this fine and beneficial adjustment the wheat midge — which would otherwise probably be such a scourge as would ultimately destroy our wheat crops — is kept down. One writer, while mentioning the fact that in one year the loss sustained in the wheat crop of one district was equal to one- third of its whole amount, and observing that all the cat- erpillars had descended into the earth by the 1st of Au- gust, counselled means to be taken under like circumstances for destroying them while in that situation. If, as seems high- ly probable, these caterpillars which do drop from the chaff scales of the ear to the ground are ichneumonized caterpil- lars, this counsel was the very worst which could be given ; for if followed, the farmer's best friend would be thus destroyed. Does not this fact show the importance of the habits of all our farm insects being thoroughly studied and known; and is it not, moreover, a remarkable instance of the fine provision made by our All-wise Creator to pre- serve the fruits of the earth, while at the same time he demands the exercise of care on the part of the husband- men, that the pests of the crop should be left in the chaff- scales where they can be most easily destroyed ; while their natural enemies or destroyers should drop to the ground, where they are best preserved to resume in the following season their saving office. Professor Hind, in the paper already alluded to, gives much information as to the means employed to prevent the attacks of the "wheat midge" as adopted in North Amer- ica. From this we take the following, which may be sug- gestive to some of our readers : — " The remedial measure which appears to be immediately suggested by a study of the habits of the wheat midge, is of the simplest descrip- 124 CULTURE OF FARM CROPS. tion, and everywhere practicable. The maggot of the midge previous to assuming its larvae condition, buries itself an inch or a little more below the surface of the ground. That when the time arrives for their assuming the fly state, they wriggle themselves to the surface for that purpose. It is only by a series of alternate contractions and expansions of one side and the other that they can make their way up from an inch below the surface to the light and air, for they possess no feet, or other exposed members when in the pupa case. If, therefore, the pupa be buried, say six inches below the surface, it is permanently imprisoned, for nature has not provided any apparatus to enable it to ef- fect its escape under such circumstances. If, therefore, at any time between August and May of the following year, the ground be ploughed to a depth of at least six inches, and in such a way that the furrow slices lie as compactly as possible, there can be no doubt that a vast majority of the pupae will perish from inability to escape from their imprisonment. But how much greater the probability of every individual pupa perishing if the ground be ploughed seven inches deep immediately after harvest, and left un- touched until the follo\ving August 1 Every one knows that it is not possible, in ploughing, to turn a sod or fur- row slice completely over, so that all parts shall be altogether reversed. The furrow slices may be made to lie with great compactness, but there will be interstitial spaces into which the pupa3 may fall or wriggle themselves, and event- ually escape. When the field is ploughed immediately after harvest, not only will the autumnal rains fill the spaces beneath and between the furrow slices by washing down fine particles of earth, but the influence of many months of winter and spring will consolidate the furrow slices, and their compactness may be ensured by rolling in May, or the early part of June, before the fly ap- pears. Rolling the land immediately after ploughing is accomplished, will give further security to the pri- son in which the pupae are inclosed by this simple ar- tifice." THE HESSIAN FLY. 125 17. (a) The Hessian Fly, (b) the Thrips, (c) Wheat Stem Fly, (d) Wheat or Corn Saw Fly, (e) Wheat Para- sites.— (a) The Hessian Fly. Fortunately the farmers of this country have not had as yet the same experience of this terrible scourge of the wheat crop as the farmers of North America, where at one time, in some of the States of the Union bordering the Atlantic, its ravages were such that the cultivation of wheat was likely to be altogether arrested. Although not unknown in Europe, having been under the cognizance of naturalists as existing in France, Germany, Switzerland, and some of the larger islands of the Mediterranean \ still its ravages have been confined so much to America, that some naturalists have asserted that it is strictly an American insect. The Hessian fly is so called from the opinion at one time held in America that it was introduced into that country in 1776 by German troops taken over from Hesse, in Germany, to reinforce the British army then in possession of Staten Island, near New York. The insect is dipterous, not unlike the wheat midge (see Fig. 14), but the antennae are shorter, the wings more elongated, and the hind part of the body pointed. The scientific designation of the insect is cecidomyia distinctor. The fly lays her eggs on the leaves of the young wheat in November and May. When this is done with autumn sown wheat, the plants in spring assume a straw colour and appear to be withered ; the shoots only to which the maggot is attached wither thus. The maggots appear to live by suction merely, as they do not incise the stem or otherwise injure it. When the autumn maggot has arrived at its full growth the outer skin becomes detached, and serves as a case first for a larva, and secondly, for a pupa or chrysalis case. The outer skin becomes hardened, and within the protecting case the maggot remains throughout the winter months. As spring approaches, the larva changes into the pupa condition — still within the same case — and, after remaining in this condition for eight or ten days, the pupa works its way up through the soil to light and air, where it emerges through the case, which now cracks, arid 126 CULTURE OF FARM CROPS. assumes the form of the Hessian fly so much dreaded by the American farmer. Very numerous have been the plans proposed to stop or prevent the ravages of this fly ; these possessing no great practical interest to our readers, need not be detailed here, but it will be interesting simply to name them. They are, (1) growing wheat in a fertile soil, or making soils, otherwise poor, rich with judicious manur- ing ; (2) late sowing of seed ; (3) grazing ; (4) use of the roller ; (5) mowing ; (6) steeping the seed in various eub stances ; (7) growing oats as a decoy; and (8) wheat as do. ; (9) deep covering of the seed ; (1 0) sun-drying the seed ; (1 1) procuring seed from unaffected districts; (12) sprinkling salt, ashes, or caustic lime over the young plants; (13) burning and ploughing up the wheat stubble; and (14) using what are called "fly-proof wheats." Of wheats which come under this distinction are " Underbill," " Spelta," "Chmia," "Mediterranean," "Etrurian," "White Flint;' " Chidham," and (bU de rile de hoe) "Early hoe wheat." Of these remedies now named, some are more or less advantageous, some altogether fanciful. — (b) The Thrips. (Tlirips cerealium\ (thrips tritici), (coleothrips trifascicata.) Of these three varieties of the insect, the first, "thrips cerealium," is perhaps the most destructive ; it is said to have destroyed in the year 1805 one-third of the wheat crop in Piedmont. The colour of the insect is black ; it has a slender body with a long lizard-like extremity. In hot weather it is abundant to a remarkable degree ; to such an extent indeed is it present in the wheat crop, that the naturalist Kirby states that he never examined a single ear in which it was not found. The opinion of this naturalist was decided that it derived its nourishment from the grain ; an opinion in which Linnaeus also coincides. It is said to infest wheat grown upon strong heavy soil more than those grown upon light ones ; and crops sown late than those sown early. — (c) Wheat Stem Fly, (chlorops pumilionis). The colour of this fly is black, at least its upper part, the under side of the body being pale yellow. The maggot is small and of a white colour, the pupa yellow, smooth, and shining. The THE WIRE-WORM. 127 maggot attacks and destroys the central shoots of the plant, dwarfing the lateral ones which are pushed out on the de- cline of the central stem. — (d) The Wheat or Corn Saw Fly, (" cephus pygmoe.as") is small in size, of a shining black colour ; the larva is of a yellow colour with a dark head. It takes up its abode within the stem, which it gradually eats away. — (e) Wheat Parasites. These are supposed to be very numerous — we say, supposed — for not much is known either as regards their numbers or their habits. The wheat louse, " aphis cerealium," is a green-coloured insect with dark longish horns ; it infests the ear for some time preceding harvest. The Corn Bugs ('• miris tritici" and " miris erraticus") are found frequently attacking the ear of the plant in its various stages. Nothing is known defin- itely as to their habits. To the insect pests which we have now described, we may here add that the grub of the cock- chafer ("Melolontha agricola"- and (i Melolontha ruficomis") and the caterpillar of the winter moth (noctua tritici) at- tack and do great injury to the wheat plants in their various stages. Formidable, however, as is the list of the insect scourges of our wheat crop, that list is not yet exhausted ; there remain, at all events, two to be named, which are as destructive, if not more so, than any yet alluded to. These are the " wire- worm " and the " grub." 18. The Wire-Worm. — While certain crops have what may be called their own peculiar insect scourge which affects it alone, or at least plants of the same natural order, as the turnip fly the cruciferae, and the midge and Hessian fly the graminse or cereals ; the true wire-worm is such a universal feeder that no plant can be said to be safe from its ravages. What therefore we have in the present divi- sion of our work to say about it, although referring speci- ally to the oat crop, will also have a practical bearing upon the wheat crop, which is perhaps more ravaged by this pest than any other crop, and for reasons stated in next paragraph. In practice, it is the habit of farmers to class all grubs and worms under the designation of wire-worms ; this has of course given an appearance of much greater importance to 128 CULTURE OF FARM CROPS. the ravages of the wire-worm, so called, than is properly due to it ; but as that able entomologist, Mr. Curtis, ob- serves, the true wire- worms " have enough to answer for on their own account, and the great ignorance," therefore, " that has existed regarding them," gives a high degree of practical utility to all remarks bearing upon their charac- teristics and on the best mode of meeting these ravages. The wire-worm is known as the elater Uneatus, other- wise the agriotes Uneatus, also, cataphoegus Uneatus. It is the larvse of a very numerous species of beetle of the genus elater ; as many as sixty are known in this coun^- try, and are all eminently destructive of vegetable life. These larvae feed upon the roots and the lower part of the stems of the cereals and grasses, and are particularly de- structive to the oat crop, arising from a very general practice of taking this immediately after the breaking up of grass land in the soil of which the eggs are abundant. The body of the wire-worm is long and slender, about one inch in length, cylindrical, made up of a series of twelve rings or segments ; the three segments nearest the head bearing three legs on each side ; the body is smooth generally, al- though provided with a few hairs scattered here and there ; the colour is yellowish, with brownish head. The length of the pupa or chrysalis — the third stage of insect life — is about one-fourth that of the larva ; its colour is whitish, and is made up of ten rings and segments, the last of which bears at the abdomen two short projecting spines ; two black spots are placed over the eyes. The wire-worm re- mains in its larvse or grub condition for several years. The "imago "or perfect insect, the last stage of insect life, is a beetle, known popularly as one of the snapping beetles or bugs ; its length is about one-third of an inch ; the colour of the body is brown, the legs a dark yellow. The name of the genus elater is given to it on account of the peculiar power possessed by the beetle of leaping up when placed by any circumstance on their backs, a characteristic notable enough, as those who are acquainted with the habits of insects know ; many will have doubt- THE WIRE-WORM. 129 less noticed beetles lying on their backs making painful but useless efforts to recover their position ; these do not trouble the genus elater. The wire-worm is often found in such marvellous abundance eating down the crops as fast as they come up, that the only remedy thoroughly effective is starving them out by keeping the land free from vegetation, ploughing and stirring it frequently, and keep- ing it as clean as possible. The birds which prey upon insects are the best friends of the farmer in many cases, not the less are they so in this endeavour to get rid of the wire-worm, vast numbers of which are devoured by them. The wire- worms are also preyed upon by an ichneumonous parasite and by several insects ; the small black shining beetle, the steropus madidus, also devours them largely. In breaking up grass land a good preventive of the ravages of the wire-worm, according to that eminent agricultural entomologist Curtis, is to shallow breast-plough it to a depth of two inches, or by paring and burning the surface before the ploughing is done. All sorts of remedies have been suggested for the destruction of the wire-worm, as steeping the seed in wine and then drying it with sulphur, liquid ammonia, and also by the growth of white mustard, a plant which seems to be particularly obnoxious to the larvse, but of which it has been said, in view of the fact, that there is perhaps no more noxious weed than this plant, when land is neglected, that the remedy may be worse than the disease. Salt, to the extent of 10 bushels per acre, and lime, 100 bushels to the acre, have both been tried, but in some cases with marked results of anything but a gratifying character. In America a plan which has been very successful, is taking a crop of buckwheat after the grass has been broken up — late ploughing and frequent, as often as possible in the autumn, then sowing pease in the spring, then frequent ploughing next autumn — this plan followed, no crop succeeding has been attacked. Curtis, in his well-known paper in the Journal of the Royal Agricultural Society, has completely exhausted •11 that can be said on the habits, characteristics, and 130 CULTURE OF FARM CROPS. modes generally adopted to prevent the ravages of this in- sect scourge of our farm crops. In the 6th paper of this valuable series (Vol 5th of the Journal, 1844), the reader anxious to go deeply into the subject will find a vast amount of matter bearing upon it ; it will answer the purpose we have in view in the preparation of these "notes," if we give here a rapid resum6 of the principal points there touched upon. Of the beetles belonging to the genus elater, or leaping beetles, which are the parents of the true wire-worm ; there are four species which most commonly attack the cereal crops. These we very briefly describe, referring to the pa- per above alluded to for a detailed description of them. (1.) The Elater sputator. This is the smallest of these four common species, its colour is variable, and is met with in our corn fields in the spring, (2.) Elater obscurus This is larger than the last species ; and like it is met with in the spring. (3). Elater lineatus. Of this Mr. Curtis says that it is "supposed by some to be a variety of the foregoing species. It is now by far the most abundant, and is found in spring and summer." (4.) Elater rufican- dis. This is the largest of the four common species, and is found in the spring infesting nettles abundantly. It is not yet determined, or if determined, not, at all events, widely known, whether the eggs are laid by the female beetle in the earth or in the base of the cereal plants. When the wire-worms are first hatched they are very small, but at- tain, when fully grown, a length of from three quarters of an inch to an inch ; their growth is slow. One remarkable peculiarity possessed by the wire-worm is the long period in which it remains in the larvae condition, namely, five years ; thrice during this period they eat off, so to speak, their outer skins ; this at intervals probably corresponding with their increase in size. Following upon this curiously interesting operation, the wire-worms are white in colour, and have tender skins; recovering, however, their normal condition of tough smooth skin, they move along the sur- face and dig or burrow into the bosom of the soil with great THE WIRE-WORM. 132 facility. Having gained the last stage of its larvae or worm condition, it descends deeply into the soil, and forming a bare walled elliptical-shaped cell there, it assumes the pu- pa or chrysalis form, this taking place somewhere about the end of July or the beginning of August, and retaining this pupa condition some three or four weeks, probably, however, for the whole of the winter in some cases where buried deeply in the soil. Early in August, however, is the period, ascertained by observation, when the insects work their way through the soil and commence their life on its surface as the perfect beetles. These " beetles run with their heads down, and drop when approached; they also Jiy ivell, and are perfectly harmless, feeding only on flowers." Of all the cereal crops the oat crop suffers most severely from the attacks of the wire-worm; so much so that "some- times it compels the discouraged farmer to lay down valu- able land as pasture, to a very great disadvantage." The barley crop suffers from the attacks of the wire- worm, these being indicated by the change of colour which in spring time the crop undergoes from a healthy green to a sickly yel- low. The wheat plant also suffers very much from the at- tacks of the wire-worm, which are said to continue through- out the whole of the winter; but Mr. Curtis takes leave to doubt whether this is the case, " for during severe frosts," he says, " they descend into the soil like the larvae of the cockchafer, retiring deeper and deeper as the cold increases ; " but early in the year, depending greatly on the tempera- ture, they make ample amends for their fast, if such be the case, by diminishing, if not destroying, this important crop." The wheat crop, when taken after a clover ley, is sure to suffer worse after this than after any other crop ; " Indeed," says Mr. Curtis, " when white clover, or suckling, and rye- grass layers have been left for seed, it is scarcely possible to get a wheat crop on account of the wire-worm." As regards the soils most likely to favour the develop- ment and habits of the wire-worm, a few notes will be use- ful and suggestive. Land bordering on marshes, and con- sequently with a spring and friable soil, is very subject to 132 CULTURE OF FARM CROPS. attacks of the wire-worm. Gravelly and sandy soils have. in some neighbourhoods been found most affected. Waste and wood lands, and old pastures, are "harbours for the wire- worm." As a rule it may be accepted that "gravelly and sandy soils are most infested, strong loam and clay most free from them." Having thus glanced at the habits of the wire-worm, the crops which it attacks, and the soils in which they best flourish; we shall, in our next paper, take up the consideration of the best means, or at least those usually adopted in practice, either to prevent them from committing their ravages, or at least greatly to modify them and reduce them to a minimum of mischief. 19. The Grub.— The grub of the farm fields—par emi- nence, the scourge of our corn crops — is the larvse of a fly known vulgarly as the " daddy longlegs," " spinning-maggie," and to natural historians as the "crane fly." Mr. Jamieson, in one of his "Fordyce Agricultural Lectures," thus describes the habits of the grub: — "The fly makes its appearance in greatest strength in July and August, and shortly after lays its eggs. The number of eggs laid by one insect is very numerous — in one case he had counted as many as 600, but the usual quantity was probably about 300. They were deposited in grass land in a great variety of situations — in meadows, in lea-lands, by roadsides, the skirts of plantations, in garden lawns, and even in the turf on the roofs of cottages. How long the eggs lie before the lame come out is not known, but, probably, the majority were hatched in autumn or before winter; and they would be found in the grub or larva state from January to August. The eggs being deposited in grass land, it was accordingly in the corn crop which had been sown in land ploughed up out of grass that the larvae made their appearance — that was to say, in what farmers called their lea-corn. It was rarely that they were found in the corn following a crop of turnips — neither was it found in a yaval crop, or a crop of corn taken upon land that was under a grain crop the pre- vious season. Although not complained of, there could be no doubt that the grub is as plentiful in grass-land or pas- THE GRUB. 133 ture as among lea-corn; for a case is mentioned in the spring of 1813, where in Holderness, in Yorkshire, several hundred acres of pasture were destroyed by the grub. Grass plots in London were said to be attacked by them, as well as many garden plants, such as lettuce, dahlias, car- nations, &c. It was related too, that in some of the mid- land counties of England, where they are in the habit of taking a crop of potatoes after clover, it has been found necessary to breast-plough the turf and burn it before planting the potatoes, to prevent this grub from destroying the crop. In France also the grass land suffers from it. "The grub remained under turf and flat stones during the day, coming out to feed after dark, and during the night they might be found eating at the tender blades of the young braird. It is probable they attack the roots, but it seems to be the green blade they prefer. About the month of July, the grub assumes the state of a pupa or chrysalis, casting its skin, and being covered by a brownish membraneous case; and after a week or two the brownish membrane covering the head and thorax splits, and the creature having wriggled up to the surface, gradually extri- cates its limbs from their covering, and out it comes as the Daddy Langlegs — certainly a most marvellous transfor- mation. " The grub was not a new pest ; for it was known long ago under the name of the ' torrie-worm.' Some people said that guano and other artificial manures now in use helped to breed grub. This notion was very like that of the farmer, who answered Sir Robert Peel's advice to get some improved implements, by saying, 'We farmers, Sir Eobert, have got an idea that iron ploughs breed weeds.' In England the grub was particularly abundant in 1816, 1817, and 1818, and was not much felt again until 1829 and the following years. From our experience here it would seem that grub abounds in certain seasons more than in others ; but he had no doubt that there was more or less grub every season, though their effects are not al- ways equally marked. Many farmers were of opinion that 134 CULTURE OF FARM CROPS. a frosty winter did good service in ridding them of the grub ; but it was to be remarked that there had been very severe frosts in some of our recent winters — that of 1860, for example. Snowy winters were also said to kill the grub. As to the truth of this he could not vouch ; but it was the fact that our winters lately had been pretty free of snow, so that this notion was so far supported." We now proceed to the consideration of the practical points connected with the modes of best meeting or prevent- ing the ravages of this scourge of the farm. Much has been written upon this important subject descriptive of the attempts which have been made from time to time to pre- vent the ravages of the grub ; so much, indeed, that the space of one of our volumes would not suffice to do justice to even the most rapid of resumes of it. We can therefore find space to glance merely at what has been most recently expounded in connection with the subject. At a recent meeting of the Fettercairn Farmers' Club, Mr. Scroggie stated what appears to us to be the true mode of dealing with this scourge — namely, in the preparation of the soil for the sowing of the seed; that it is not in the after-ap- plications to it, as top-dressings of this or that manure, nor in the preparation of the seed, as in the case of wheat, but in this, and this only, the preparation of the soil The habits of the grub lead us inevitably to conclude that the proper condition of the soil seems to be best brought about by attention to two things — first, by burying the surface of the lea ; and, second, by well rolling and consolidating the ground. The one without the other will not suffice, more especially the mere rolling, inasmuch as, if the grub gets fairly possession of the soil, no amount of rolling seems to have any effect upon its vitality. But by burying the surface of the lea we bury also the eggs, and exclude them from the adjuncts necessary to bring them into life — the air, the heat, and the light; and then by rolling we con- solidate the ground, and prevent the newly-hatched insects from "burrowing in search of food." The modes, how ever, of burying the surface of the lea, and, by consequence, THE GRUB. 135 the eggs which it harbours, will vary as the circumstances of the soil or locality. In good soil, free from stones, the plough, with its skim-coulter, with running or dragging weight and chain, will be found an efficient implement, peeling or paring off the rough surface, and depositing it in the bottom of the furrow. In cases of stony, rough soil, this implement would not be adaptable, the plan then to be adopted being the taking of a light furrow in the first place, and then following this up by a deeper furrow in the same trench. But in place of using two implements one might be arranged; and we are inclined to believe that Hancock's Pulveriser Plough would be found efficient, for not only will it effectually bury the surface lea, but it will bring the soil into that finely pulverised condition so es- sential to the healthy and rapid development of the plants. And this rapid development is of most vital importance in the case of a corn crop likely to be attacked by grub, just as much so as it is in the case of the turnip crop, to bring, with as great rapidity as possible, the leaves into that stage where they will best resist the attacks of the fly. We be- lieve, indeed, that in a method of applying manures to the crop so that this rapid development of the plant in its early stages is secured, lies the secret of success of growing the corn crop free from the ravages of the grub ; always, of course, in conjunction with the good preparation of the soil and its after consolidation. Before the seed is sown, it ap- pears to be a good plan to give the soil a thorough harrow- ing, and after this a good turn of a heavy roller should be given. After the seed is sown it is covered in by a double stroke only of the harrow, after which the roller is passed across. By this means a shallow covering for the seed is secured, which will tend in like manner to secure a much more vigorous brairding or development than would be the result of a deeper sowing. If the land is poor in quality, this vigorous development will be further insured by giv- ing a top-dressing of some artificial manure, of all of which nitrate of soda is probably the best, this being mixed with common salt. Salt, by the way, is stated by some to be a 136 CULTURE OF FARM CROPS. 'perfect cure' for the grub; but of this, as of all applica- tions having a similar aim — namely, killing the grub — it may be accepted as a truth that before you can apply as much of it as will be necessary to kill the grub, you will run a good chance of doing something more than that — killing the corn, a consummation by no means devoutly to be wished. In this, indeed, as in other things, 'prevention is better than cure.' And the naming of this time- honoured proverb — honoured, we fear, in too many cases, more in the breach of it than in the observance — brings to our recollection two capital papers on the prevention of the ravages of the grub, which proceeds upon the principle that prevention is better than cure, and that this prevention is secured by no mode so effectually as by arranging the rota- tion of the crops of a farm, and the modes of working the soil for these, in such a way that they will have a direct re- ference to the habit of the grab. The papers alluded to are first, one from an American Journal, and secondly, one recently read by Mr. Johnston at the Fettercairn Farmers' Club, and of it we below present a very brief resume, giving first that from the American Journal, which opens thus suggestively : — " Nothing can be applied to the land suffi- ciently powerful to destroy them. You cannot poison them, but you can make the land unfit for a wire-worm to live- in it. " If you observe attentively a field in which the wire- worm is beginning his depredations, you will see that the latter commence where the ground is loosest, and that they spread from there slowly to all sides. If, perchance, two furrows have been thrown together in ploughing, so form- ing a sort of ridge, the worm invariably commences to eat along this ridge, where the ground is drier and more loose than on the rest of the field. We see this very plainly here, where all fields are thrown together into lands or ridges, which are from 1 to 3 rods wide, and whose ridge sometimes is 2 to 4 feet higher than the furrow. This is by no means a commendable practice, and is more and more disappearing, but it still exists, and where it does so, THE GRUB. 137 there the wire-worm first destroys the crops along the ridges and gradually descends towards the furrows. Ano- ther experience is, that the wire-worm is particularly dan- gerous to such crops as are preceded by clover, the rotting remains of the clover keeping the soil loose and dry. Even more ! we have whole tracts of land which formerly were wet and stiff, but of late have quite changed their qualities by being underdrained. .Now on such lands the wire-worm was entirely unknown before the drainage; but as soon as the drains were showing their effects the wire-worm made his appearance, and soon became a great plague. "Now to the remedy. Destroy the looseness of your land, and you will not be troubled by the wire- worm. We have taken a flock of sheep and driven them up and down on a field sown previously with oats, and there never ap- peared a worm as far as the sheep had come, though the rest of the field had to suffer hard. 'The sheep has a golden foot,' says an old adage; their small feet are the best roller known, but it is an expensive job ; our shep- herds hate it ; it is no advantage to the flock, and 400 sheep can do only a small day's work. So we employ other means. " Five years, ago we used to think that thorough har- rowing was the only means to prevent depredations by the wire-worm. I have frequently heard some of our best and most successful farmers say that the fate of the crop de- pended on the harrow. I have seen fields harrowed twelve and even sixteen times after the throwing on of the seed. My old chief had a walking-stick with a sharp point, and he was all day walking over the field to try whether he could find a loose spot. He would push his stick into the ground, and as long as a hollow place was to be discovered the teams had to keep on. ' The horses' hoofs must tramp it hard,' he would say, when our patience sometimes be- came exhausted. Frequently when I thought of sending the teams home for the night, he would come out with his stick and the tired horses had to begin anew, and many a field was so treated hours after the moon had risen. I say K 138 CULTURE OF FARM CROPS. this because I know that in America, especially in the west, little attention is being paid to harrowing. You consider mostly the job done when the seed has been covered. I had been engaged in farming for nine years in the States, and when in 1859 I tried my hand at it here I at first shook my head at so much harrowing, and thought it an unnecessary expense. I know better now. Thorough har- rowing is the first rule of good tillage ; it is the best re- medy against the wire-worm. But we have introduced better implements of late ; the harrow alone does the work too slow, and not good enough ; we now employ iron roll- ers made in sections similar to Croskill's clod-breaker. We roll the land before and after seeding, and one rolling often has more effect than four rounds by the harrow ; the roller cannot be too heavy; it packs the ground and de- stroys the haunts of the worm. Smooth rollers could not do this ; they merely pulverise and press the surface and are often dangerous to use — if the surface is reduced to powder, a rain will bake it into a crust. We want the land packed at the bottom of the furrow — open on the surface. I am satisfied that if we could, by steam power, drag a roll- er of 10,000 pounds over the field, this would pay better than to use one of 800 pounds. Smooth rollers, however, I regard with distrust. " Sometimes at seeding time the land will be so dry that even by the aid of the roller it cannot be packed. In this case we roll the land after the seed has come up. Oats will bear such an operation very well when the young shoots are 2 to 4 inches long ; winter wheat will bear it in the spring, though not with a smooth roller. It hap- pens, that owing to dry weather or other circumstances the field remains too loose, and the worm begins his work of destruction. In this case we use, with best success, liquid manure. I have drawn such liquid manure upon an oat- field in May, where the wire-worm was committing the greatest depredations. Of course the wheels of the wag- gon injured the appearance of the field, which looked like a garden before ; but they did not injure the crop. The THE GRUB. 139 tracks of the wheels soon disappeared under the reviving haulm ; the worm was completely routed, and we harvested a tolerable crop of oats. The worm cannot bear the smell of liquid manure from the tanks, but the latter must be applied on growing crops to have effect. When applied before seeding, it loses its smell too soon. I used to pump water into the tank and stir up the old settlings (the tank being very large) to make the stuff last, so that I have had nearly 100 loads (for four oxen each) drawn in a season, and saved a good many acres of oats. " The above are facts proved by experience. Let me add that sometimes after a cavalry manoeuvre on seeded fields, the whole crop seemed destroyed by the horses' hoofs, and consequently was taxed and the owner indemnified; but afterwards the crop revived and gave a highly remunerative harvest. We must loosen the ground by ploughing, but we cannot pack it too much afterwards for crops of small grain, barley excepted, provided wre keep the surface from baking." Mr. Johnston, while, however, in the second paper above alluded to, advocating, as the main features of his preventive measures, a change in the rotation of the cropping, nevertheless holds that other remedial measures are necessary. But a few sentences back we alluded to the use of salt as a preventive. Our authority, in a certain way, advocates the use of this, with a view to attack, and, if possible, poison the grub at that stage of its development when it is weakest. With our unfortunate ignorance of the real habits of the grub (what a fine opportunity, by the way, for our agricultural societies to do something in the way of inquiry and observation in the complete mode we have more than once in the course of our papers advo- cated !) we do not know precisely at what period of the year it is in its weakest condition. Mr. Johnston, however, conjectures that this is in the month of February; and as the attacking and poisoning agent is salt, he recommends this to be applied in this month at the rate of 10 cwt. per acre, harrowed well into the soil, and the land thus pre- pared seeded with oats four or five weeks thereafter. Our 140 CULTURE OF FARM CROPS. authority is, we need scarcely say, an advocate for means to be adopted for disturbing by mechanical means the con- ditions necessary to mature the egg into life by breaking up the surface of the lea, or by skim-ploughing, having for aim the complete burying of the surface beneath a good fur- row. As to breaking up of the lea surface, Mr. Johnston is of opinion that before ploughing it will be advantageous to harrow the surface, by which means not only will the sur- face be disturbed, but much of it will fall to the bottom of the furrow. Eibbing or stripping the lea, and then harrowing down the cut-up slice is thought well of by some ; but our authority is inclined to think it not of much value. He says that his latest experience shows that the more finely the soil is pulverised or triturated without the clods being cut up with it, the better for the crop. In skim -ploughing, where it is difficult — as in some cases it will be found to be — to attach a skim-coulter to an ordinary plough, Mr. Johnston recommends the first ploughing to be done with a one-horse plough, taking a slice as thin as it can be easily taken — say two inches thick. This being thrown into the bottom of the furrow, the next ploughing is done by two horses, and the plough brings up a good rough furrow, completely burying the sward at a depth of from five to six inches. While on the subject of ploughing or preparation of the soil, it is worthy of note that our authority distinctly opposes the fine, high-set, angular furrow-slice which some seem to think highly of, and which, indeed, by many of our most eminent agricultural authorities, has always been looked upon as the very highest standard of ploughing. Those high-set ridges or furrow-slices give corresponding angular depressions or hollows, which, our authority believes, or is inclined to believe, act as shelter-places for the grub to be developed in at early spring-time. Further, the seed, as it is sown broad-cast, falls mainly into these furrow-depres- sions ; and brairding actually provides, or at all events seems to us to provide, a supply of food for the grubs there located, without involving any trouble on their part to go THE GRUB. 141 and look for it. When we see so many things in farm practice nowadays tending to do away with the notion that the only way to prepare the soil for cropping is to throw it up in the angular furrow-slices so long known and carried out, and to prove that other modes, as grubbing or the like, are better, it will be odd if another reason is found against ordinary ploughing, and in favour of other modes of pre- paring the soil, in the fact that the latter are more likely to prevent the ravages of the grub. But while advocating remedial measures such as we have adverted to, Mr. Johnston strongly insists upon the impor- tance of introducing rotations other than those now in vogue, and which are more likely to meet the circumstances of actual practice. When we remember that green roots and leguminous crops have all hitherto resisted the at- tacks of the grub — if they are, indeed, liable to them — we see that, by introducing these methodically into the rotation, so that we ' have our whole lea broke under one or other of such crops as turnips, potatoes, rape, cabbage, beans, or pease, we will have stolen such a march as will tend to certain victory.' Mr. Johnston suggests that the whole might be placed under potatoes; but, in view of the difficulties attendant upon the lifting of these in many lo- calities, he suggests one-third of the ' break ' to be in po- tatoes only; one-third to be in tares — those tares to be sown between February and June in rotation, so that by the time Swedes fail the farmer, he will have a capital green food to replace them, and as the rotation crops of the tares come into use, they will likely give a supply of food up to September or turnip time; the remaining third of the ' break ' to be rape for sheep, and cabbage for cattle. Mr. Johnston says that he has no experience of the value of rape, yet he believes that it must be good, else it would not be so much grown in England as it is ; and we think he is right in this. We know something of the culture of rape, and of its value as a feeding material not only for sheep but for cattle — the latter, so far as our experience goes, being remarkably fond of it — and we confess to some 142 CULTURE OF FARM CROPS. surprise that it is not more frequently grown on soils adapted for it. We purpose, in the volume of this series treating of Forage Crops, to present our readers with a few Notes in connection with this crop. As to the value of cabbage as a feeding crop little need be said here, albeit some notice might be taken of the ignorance of some of our practical men as to this. In the case of those who wish to 'be relieved,' as our authority terms it, of the tares, beans, the cabbages, or the rape, he recommends them to take as many potatoes as they wish, or take two successive crops of oats, or if not a second crop of them, one of barley. This will by some be deemed most heterodox advice ; and yet a great deal can be said in favour of the plan of taking two cereal crops ; and we have known it, as indeed we now know it, to be practised successfully. Nor need the faet be the less encouraging to those who are desirous to break through the prejudice (shall we call it?) existing upon the point, that the first of our practical, as the first of our chemical, authorities are in favour of the practice ; certainly they are of opinion that it is not productive of the evils that some blame it with. But although two cereal crops may be taken in suc- cession, our authority recommends the practice with modi- fications. The following is the rotation which he names as being most likely to commend itself to every intelligent proprietor and factor, as well as make it easy to the farmer : — ' Grass three years, save the part made potatoes, which will only be two ; 3d, potatoes ; 4th, cereal crop ; 5th, turnips ; 6th, crop sown down with grass. If two white crops are wanted — and, with good farming, no reasonable proprietor, unless ignorant, would object — we would say, three years grass ; 4th year, potatoes of a part, while the other part was oats ; 5th year, all the break, oats or barley ; 6th, turnips ; 7th, crop of barley sown down with grass seeds. It will be noticed that there are only two crops taken from the part broken up for grain at three years old — the other part made potatoes ; only one crop of oats is taken from it.' Such are the suggestions made by Mr. UNSOUNDNE3S OF GRAIN BY INSECTS. 143 Johnston on the subject of a change in rotation. It has been taken up by other authorities during the last few years, and will yet more, we venture to say, be taken up. If the discussion which will ensue does no other good than directing attention to, and promoting inquiry upon, all the points connected with the theory of rotation, it will do great service to agriculture ; for the truth is, we are by no means assured of what really constitutes a correct prin- ciple in rotation, or whether — which is, we fancy, much more likely to be the case — the phenomena attendant upon the change of crops are not invariable but rather are variable, being dependent upon a wide variety of circumstances tend- ing to introduce a corresponding variety in practice. The whole subject has, indeed, to be gone thoroughly into before information can be eliminated which will be of trustworthy service to farmers generally. Is this another subject, in ad- dition to the many we have already indicated, which ought to be taken up by one or all of our agricultural societies ? " DIVISION SECOND. THE STORING AND PRESERVATION OF WHEAT. SECTION FIRST. CAUSES OF UNSOUND GRAIN INSECTS MOISTURE. 20. Insects which Cause Unsoundness and which De- stroy Stored Grain. — The depredations which insects com- mit upon the wheat crop are not confined to those in the field, which have been described in last section ; but they are carried out, and with remarkable vigour, in the places in which it is stored. The following is an account of the insect pests of stored grain : — "(1) The Weevil (calandria f/ranaria) is a snout beetle, about one-eighth of an inch in length, with a slender body (see Fig. 1 8, in which we give a diagram of the weevil, natural size, with part of the head magnified), of a dull reddish brown colour, furrowed 144 CULTURE OF FARM CROPS. j». lg wing-cases, and long punctured thorax. A single pair of these insects may produce six thousand descendants in a year. They are destructive to stored grain in both the perfect and larva state. The female lays her eggs in wheat in the granary. The young maggots burrow into the grain and consume its contents, leaving only the husk. Their transformations are perfected within the husks they have chambered out in the larva state, and so secretly are their operations conducted that it is impossible to detect their operations by simple in- spection of a heap of wheat. The presence of these in- sects may be detected by the weight of the grains ; on throwing a handful into a bucket of water the diseased grains will float. After the female has, by means of her rostrum or beak, deposited an egg in the grain, she covers it up with a sort of glue of the same colour as the husk, hence the difficulty of detecting the presence of this depre- dator in the granary during the time when it is in the larva state. On the approach of cold weather the weevils retire from the heaps of wheat and seek shelter in crevices and cracks of the floor and walls. They remain torpid for a while, and after having paired, soon die. They avoid the light, hence one reason why constant turning of the wheat and sifting is advantageously employed to drive them away. They lie in general four or five inches below the surface of the heap, and here the majority pair. Kiln drying appears to be the only certain destruction to this pest. Frequent turning and airing of the heaps, whitewashing the walls, and sweeping the granaries very clean, with abundant venti- lation, are artifices strongly recommended for the purpose of diminishing the numbers of this pest. It is not likely that farmers in Canada will suffer much from its depreda- tion for some years to come. Where large quantities of wheat, and particularly of foreign wheat, are allowed to accumulate in store, there, no doubt, the ravages of this insect will be felt, (b) The Wolf or Little Grain Moth, UNSOUNDNESS OF GRAIN BY INSECTS. 145 (Stnea Gronella). (In Fig. 19 we give a drawing of the Fi" 19 caterpillar and of the moth, natural size). Mr. Curtis says that this moth is completely esta- blished in Britain, as well as in every part of Europe. The late Dr. Harris says, that from various statements, deficient, however, in exact- ness> ne was le(^ to believe that this insect, or an insect exactly like it in its habits, prevails in all parts of the country. Since its existence is quite established in America, and its known habits are such that it may at any time appear in destructive numbers in Canada, a notice here of its general appearance and peculiarities will not be out of place. From April till August the moth is found in granaries or magazines, resting by day on the walls and beams, and flying about only at night, un- less disturbed. The female lays one or two eggs on each grain of wheat, until she has deposited thirty or more. They require the assistance of a magnifying glass in order that they may be distinguished. The small white worms penetrate grain and close up the aperture with their round- ish white excrement, which is held together by a fine web. When a single grain is not sufficient for its nourishment the larva unites a second grain to the first by the same web, and thus ultimately adds together a great number. In August and September they arrive at maturity, when they leave their wheat heaps and seek for a place in which to undergo their metamorphosis. They form cocoons by working bits of wood into their web, in any chink of the floor, walls, or roof. These cocoons look like grains of wheat dusted over. They assume a chrysalis state in March, April, and May, according to the season. In two or three weeks they take the form of the perfect -insect or moth. The following remedies are suggested by Mr. Curtis : — Floor of granary scoured with soft soap and well brushed with a stiff broom, roof and beams whitewashed. The moths maybe destroyed in spring by burning lights or lamps in the granaries where they abound. All cracks in the floor or walls should be stopped with plaster of Paris, 146 CULTURE OF FARM CROPS. and apertures for ventilation secured by fine gauze. Burn- ing sulphur will kill the moths. Grain should be cut early to anticipate the appearance of the moth." 21. Unsoundness of Wheat Caused by Moisture. — This subject has not yet received the consideration which we think it deserves ; comparatively few, indeed, know the extent of the loss sustained every year through grain which has been got in and stored up in a damp condition. Tak- ing wheat as the most important of our cereal crops, let us glance at the points involved in connection with the main- tenance of or improvements in its quality. Wheat yields the largest percentage of nutritive matter of all our cereals ; while in grinding, oats lose about one half, barley a seventh, wheat loses only a fourteenth. But this assumes that all are in their best condition for grinding, a point too often overlooked. The amount of water or moisture in wheat is one of its important features ; it varies in the flour obtained from it from 12 to 18 per cent. This is greatly dependent upon the climate. Boussingault notices the interesting fact, that the wheats grown in the north of France are ex- ceedingly difficult to be kept in consequence of the high percentage of moisture which they contain, as high as from 16 to 20 per cent. Experiments made by this eminent agricultural chemist showed that unless these grains were kept in hermetically sealed vessels they rapidly deteriorated in value. But when the moisture was reduced one-half, like the wheats of the south which contain 8 to 10 per cent., the conditions were changed. Where much moisture exists in wheat, decomposition rapidly sets in, and this con- siderably lowers the flour-producing value ; and if allowed to go on, so changes the nature of the grain that bread flour cannot be made from it at all. Flour obtained from dry grain gives a higher yield of bread, although the quantity of flour may be less than from plumper and moister grain. Age has no deteriorating effect on sound grain. In Poland grain has been kept sound for half a century, and in Dant- zic grain is kept in warehouse for seven years without any deterioration. The pecuniary loss sustained by sending in TO PREVENT UNSOUNDNESS OF WHEAT. 147 damp grain to the market is very great indeed ; in this country the subject has never been investigated in the manner which its importance deserves, not so in America where men of science have taken it up with spirit. In that country the estimated annual loss has been reckoned at from £600,000 to £1,000,000 sterling. Moisture with heat — a condition almost invariably the result of stacking or storing badly got grain — reduces the quantity of gluten which it contains, this constituting the most nutritive portion of the grain. Sporules of different kinds of mush- rooms are also developed in consequence of moisture, these generally appearing in the flour or in the bread made from it. The best test of the value of wheat flour is the quantity of bread made from it, and we find that the drier and sounder the grain the greater is the yield of bread. A quarter of good flour has yielded 13 Ib. more of bread than the same quantity of bad flour made from moist and therefore unsound grain. All authorities have agreed in condemning the practice adopted by our farmers in send- ing undried corn with moisture varying from 15 to 20 per cent, contained in it into the market ; and numerous cal- culations have been made, more or less accurate in detail, yet all clearly showing the existence of a loss to the farm- ing community of serious importance, as well as from the habit of storing up grain in sheaves in a damp condition. It is quite obvious that a method or methods of increasing the bread-producing powers or qualities of a wheat, as well as of its keeping qualities (so that it may be easily stored without loss), must be an immense advantage to the farmer. SECTION SECOND.— METHODS ADOPTED TO PREVENT UNSOUND- NESS IN WHEAT ARISING FROM MOISTURE THE STORING OF WHEAT. 22. There is no department of farming in which the value of the old proverb is so apparent — "prevention is better than cure" — as that in the harvesting of the cereal crops, that is, getting them secured in such a way that the grain 148 CULTURE OF FARM CROPS. will be put up in a condition best calculated to preserve their valuable qualities. When the weather at and during the period of harvesting is, and for some time before has been fine, rains absent, and abundance of drying sunshine and favourable breezes, the securing of the corn crop is a matter of comparative ease ; but when the reverse of all this is the case — not by any means unlikely in this our variable climate, with its "weeping skies and blustering winds "- it is a matter of the highest importance that we should know the best plans of harvesting, and how to carry them out. The securing of corn crops naturally divides itself into two departments ; first, the cutting and stocking or sheaving in the fields ; and second, the stacking and ar- rangement of the stack or rick yard. It is not within the scope of the present volume to treat of the modes of cutting corn crops now adopted in practice, namely, reaping by the sickle, mowing by the scythe, and cutting by the reaping machine — what we have here to concern ourselves with is the tying up or putting in sheaves of the corn cut by any one of the above methods. The first process after the cut- ting is the " gathering ; " and the second, the " putting up the gathered corn in sheaves." On these the following re- marks by a writer in the " Mark Lane Express " will be useful here : — " A successful gatherer takes up the cuts in the swathe as the mower leaves them, cut after cut, if the swathe has been properly laid, until she has a sheaf. This is a very nice manipulation, and upon its proper perform- ance the character of the sheaf in a great measure depends as to how it can be bound and stocked. It, therefore, re- quires a somewhat more detailed notice. " In gathering a sheaf, three things have to be attended to, besides keeping close up to the mower. It has, in the first place, to be made of the proper size — small, in a wet year like this ; next, the straw has to be kept straight ; and then, it must be properly laid in the band for tying. " We must, therefore, attend to the links of our chain ; and the first link is this : One cut, or so many separate cuts (a cut being the quantity of corn cut and brought HARVESTING. 149 round at one complete stroke of the scythe) must go to the sheaf. One cut will sometimes make a small one ; in other cases, two or more may be necessary, just according to the quantity cut and separated from the uncut corn at one stroke of the scythe '; In the next manipulation, the straw has to be kept straight, and the butts even, in order that the sheaf may, in the first place, be loosely and properly bound, and in the second place, that it may afterwards stand in the stook. " The last thing the gatherer has to do in her work is the laying of the sheaf she has gathered into the band. Small sheaves are more easily handled than large ones, and for this reason are generally better laid into the bands for binding. When the bandster also stooks, the gatherer makes the bands. Eut in the case of a wet season and small sheaves, it is better to make the stooking a separate job, when the bandster makes the bands. In this case the last manipulation of gathering and the first of binding a small sheaf become a sort of joint process, the binder sometimes taking the band for the next sheaf out of the one he has just bound, but sometimes from the sheaf that is being gathered, while occasionally the gatherer drops the small handful for him with which to make it ; the two thus working to each other's hands. But, whichever of the three ways it may be, the bandster generally contrives to have hold of one end of the band while the gatherer is putting the loose sheaf into it " We now come to the work of the bandster ; and the binding of a small sheaf loosely, ' so that the sun may shine and the winds whistle through the stook,' and that the sheaf itself may, after all this, and the handling it sometimes gets, go to the stack-yard without breaking or losing any of its contents, is a very fine piece of workman- ship. It must first be properly balanced in the band ; next it must have an even bottom on which to stand ; then the top requires to be such as to defend a shower, while the middle must be straight to support weight ; and, lastly, the knot or tie of the band must be properly made so as not 150 CULTURE OF FARM CROPS. to undo in the handling, These several manipulations are but the work of a moment, and unless they are all properly done, the sheaves can never stand as they ought to do in a stook, but will either be leaning too much one way or else be turned over altogether by the least puff of wind. Where hood-sheaves are used, they require to be bound as close as possible to the butt, and more firmly or tightly tied than the other sheaves. But it is very seldom that corn cut with the scythe is hooded. " Our last proposition on this occasion is stooking. When the sheaves are small and the straw is very long, the work is more difficult to execute properly than when they are of an ordinary size ; but, in either case, the theory of setting a sheaf is involved in the old proverb — ' Every tub must stand on its own bottom.' In compliance with this, the bottom of each sheaf must be made to cover a sufficient area of ground, and the two sheaves opposite each other not be set too far asunder. The two sheaves, one in each hand, then get a gentle pressure down, to make them sit, as it were, sure on their seats. Their tops are next spread together, where they meet, like the thatch on the top of a stack thatched after the English fashion, in order to make them defend a shower. The simple but important art of setting a stook depends upon each couple of sheaves being thus seated firm upon the ground together at proper dis- tances from each other both ways. All this, too, is but the work of a moment to an efficient stooker ; and nothing can be more unpardonable on the part of farmers, especially in a wet season, than to tolerate the slovenly performance of a work upon which so much depends. " Where wheat is reaped with the hook or sickle and the stooks hooded, the difference of detail requiring notice is the putting on of the hood sheaves. In this, the same artistic attention is required to bring the sheaves to an acute angle at the top, as if no hoods were to be used. When the crop is too ripe, the ears large and hanging, the task is often next to impossible, especially when the straw is short and the top or ear-end of the sheaf is thicker than HARVESTING. 151 the butt. The work, however, is more easily done with the small sheaves of a wet season than the ordinary size of a dry one ; and whenever the top of the stock is too broad or flat, lay on a small sheaf along the top, then over this put the hood sheaves, taking care that the whole are stand- ing right, so that the equilibrium of forces (gravitation) shall give stability to the stook. " Success in putting on hoods depends greatly upon the stooker comprehending his work in all its practical details. The moment he sees the reason why the different manipu- lations in the setting of the sheaves are necessary, and why the whole are required to make the stook stand and the hoods carry off a shower, the cause is gained, for then he will soon learn to perform the work successfully. "We have said that a hood sheaf should be bound near the butt-end. It should also be so formed as to divide and open equally, so as to spread around the end of the stook, on the same principle that a Mackintosh waterproof is spread around a man's shoulders to keep them dry. On opening the sheaf, he will at once perceive that the interior forms an acute angle, and that the end of the stock must fit this angle, so as to make a workmanlike finish ; and, if he comprehends this thoroughly, and the angle necessary to carry off the rain over the end of the stook, he will not rest satisfied until he puts on both hood sheaves, accordingly finishing his work to the satisfaction of his employer, and more easily for himself than otherwise." There are two modes of setting up stocks of corn in the field generally used, the round and the longitudinal, and of these two the longitudinal is the most used. It is easy to see, however, that it. is not so good as the round mode. Of the relative values of these two modes Mr. Hardy has the following useful remarks : — " To protect wheat-sheaves best from wet and wind, I recommend that the stocks or shocks be formed round- fashioned, which I find, by practi- cal experience, will stand more firmly and erect, and will keep the corn in preservation far better in fickle weather, and even plumper when it is cut green, being more regu- 152 CULTURE OF FARM CROPS. larly dried, when it is too hot and parching, than in ordi- nary stooks longitudinally formed, which are exposed more to boisterous winds and driving rains on the whole length of the stook (at least, on one side of it), and sometimes on the opposite side, when the wind chances to change during the storm, where, as in round stooks, much less ears are exposed on any given number of sheaves, and only one- fourth of them are subjected much to driving rains, and that windward, let it blow from what quarter it will, north, east, south, or west, thus, three-fourths of the corn is protected and preserved. It too frequently happens that, in the hurry of harvest operations, too little care is bestowed to set the sheaves up properly, so as to ensure their not falling down and being injured, should driving winds and wet oc- ' cur. Long stooks are more subjected to those vicissitudes, and so take more harm than those of round, formation, from various other causes which might be enumerated and ex- plained. One man, instead of two, is sufficient to form round stooks ; and, if properly and carefully done, they would, were it required, stand a considerable time firm and erect, with the corn protected and comparatively safe, till suitable weather offered for carrying it to the garner. The quarter which is only exposed to the rain most very soon dries from the current of the wind around the whole stook, with less power to blow it down ; and, catching the sun all day, from its rising to its setting, are benefits which cannot be derived in ordinary stooks placed lengthwise. My method is this : First, to place one sheaf, joined firm on its botton, on the middle of the stetch (not in the fur- row) for the support of the rest ; secondly, three more firmly and equi-distantly around it ; and thirdly, three more repeated ; and fourthly, and lastly, to complete the stook, place six more outside, at equal distances around the whole, in all thirteen, pressing the ears, and lapping them as evenly together as possible. Another advantage of round stooks is, that the produce of several stetches can be placed on one, so that the land between can, if necessary, be cleaned or ploughed before the corn is carted. HARVESTING. 153 " The same rule applies to beans and many other crops. Round stooks, too, from the ears being less exposed, are better protected from predatory birds, which often commit too great havoc by devouring corn in time of scarcity, and more especially this year, from the circumstance of their rejecting the blighted corn (which, unhappily, so much prevails) and feeding upon the best. On small plots near neighbourhoods and homesteads, where sparrows frequent most, one quarter of the entire crop of wheat may be fairly stated as being destroyed by those depredators j in some cases the whole." The following, on the subject of setting up sheaves and on stacking of corn, is from an able paper read re- cently before the "Winfrith Farmers' Club:" — "In a general way sheaves of all kinds should be small, and the stitch or shock, consisting of from five to eight on each side, should be made by commencing in what is to form the middle, as by this course the sheaves lean towards the centre and stand better afterwards; each sheaf should be placed or rather struck on the ground in a slanting position (not upright and made leaning afterwards), and should meet directly the sheaf on the opposite side, so that each one may help to support the other. A very secure method for sheaved wheat, though not often practised or necessary, is that of cap-stitching, performed by first placing a sheaf on the ground perpendicularly, then placing others in a lean- ing position against it to the number say of fifteen or twenty, the object being to produce a round stitch, firm and regularly pointed at the top to receive the cap-sheaf or hood, which is made of two sheaves bound together, or, what is better, a sheaf double the ordinary size bound near the tail tightly. This sheaf is spread from the centre and lifted over the stitch, the ears drawn downward, and the reed straightened; another band round the whole completes the stitch, which is thus secure against all weather, and is a very good practice in small enclosures and in wet seasons, when from heat and moisture corn vegetates quickly, also as a means of securing those kinds L 154 CULTURE OF FARM CROPS. of grain with a delicate skin, and which consequently sprout freely. In changeable and stormy weather all sheaves should be tied as soon as the corn is cut, whether it be by hand or delivered from the machine, and it should remain stand- ing until it is fit to cut and tie, as thus during unsettled weather it is ready to bind sooner than when flat on the ground. When corn has become what is termed 'dead ripe,' it is as well (provided there is no grass mixed with the straw) to cut, tie, and stack, in the same day. There are reasons favourable to this practice, which are — first, economy, as the expense of putting the corn into shock is saved, and also corn which has * overstood ' has its ears so crooked down that it is impossible to make a shock secure from wind and weather. In the usual way, that is when a few days are allowed between cutting and carting, I con- sider mown corn tied into sheaf may sometimes be fit to stack before that which has been reaped; owing to its be- ing looser and more open in the straw, more air is admitted through it in the field and also in the stack, an advantage when it has been put together not in a very first-rate con- dition. On the other hand, sheaves that have been reaped settle down closer together when carted, producing a much firmer stack, and better adapted for the purpose of being shorn after the harvest work has been completed ; also its appearance is somewhat neater. A well-made and firm rick is desirable where rats exist in .any quantity, as I have found it to be a sufficient guard against any number of them when properly constructed and shorn before any of these vermin have made their holes into or under it. Whether the rick is constructed on a staddle or on the ground is of little consequence when treated in a proper manner, as far as rats and mice are concerned. The trim- ming should be performed somewhat after this manner. From the eave (which every stack of sheaved corn should have, to carry the rain falling on the roof away from the sides) downwards, to within about four or five feet from the ground, the uneven ends of the sheaves on the outside may be cut oif sufficient to give a neat appearance, with a HARVESTING. 155 long blade fixed in a long handle for the special purpose, or a scythe partly worn with the point taken off will an- swer nearly as well. The remaining, or bottom part, has to be shorn with an ordinary cutting-knife, taking away sufficient, it may be nearly to the bond, of the bottom sheaves, also the bedding beneath, consistent with giving this under part that closeness of the reed and hardness which, being thus obtained, no rat can penetrate, and, from the small base on which the stack is thus made to rest, the angle on the outside is such that if a rat jumps against the side it is unable to hold its position, but falls to the ground from whence it sprang. The method is very effectual and also practicable, as I have found stacks so treated within a short distance of immense numbers of these vermin to with- stand their attempts successfully a year or even two. This leads me to consider the best position for the stack, whether placed in the field or at the homestead, and this must de- pend on the value placed upon the straw, distance from the steading, state of the farm roads, horse power, &c. At the time of harvest, when the stacks are being made, the se- lection of a proper spot for each leads to the inquiry when and in what manner are they to be thrashed out, and the use to which the straw will most probably be applied? I say probably, because it sometimes happens that the straw, in its nature best suited for feeding, has been exposed to the weather, so that it may ultimately cause some devia- tion in the course pursued from that first intended; there- fore I would say, first secure for your cattle the straw in- tended for them, unless it is impracticable to do so from more weighty considerations, it may be, as regards the grain within. The stack, if intended for removal to a barn, should be placed as near as possible to it at harvest-time, for obvious reasons; it is better to do so at that season than in winter, or when its removal becomes necessary, at which latter period more horses are frequently required to cart home than would be the case at harvest. There is yet another and equally important point to be considered. When the day for removal (say in winter) has arrived, one 156 CULTURE OF FARM CROPS. should be chosen with a clear atmosphere, free from vapour, following others of a like favourable nature ; but sometimes necessity from existing circumstances will not permit the awaiting of such season; then is the advantage of having a stack situated conveniently near the barn highly to be valued. Again, a clear winter's morning is not always followed by a fine day, and the work of removal having commenced — a storm overtaking loads by the way — the greater the distance the loads have to travel the more in- jury to them results in consequence. Even in such case, if no rain actually falls, a lengthened exposure to the at- mosphere tends to give the grain a damp condition. I do not object to making stacks in the field when it is to be thrashed by steam; but the spot selected should be adja- cent to a good road, so as to enable the corn and straw to be drawn separately to the homestead if required. Thrash- ing, whether conducted in the field or in the barn, has each its own proper season, and should be carried on with greater regard to atmospheric influences than is frequently observed. It may be prosecuted away from the barn in the open air during the summer months when fine weather prevails, and thus the corn may derive much benefit from the sun's rays or a drying wind ; but I consider that during the two last and two first months in the year, viz., No- vember, December, January, and February, it is preferable in most cases to transfer the greater portion to the barn ; an exception may occasionally be made, such as during frosty weather. It is in some measure due to the carrying on of out-door thrashing by steam power at all seasons of the year, as pursued by many, that complaints from factors and millers are sometimes made of the condition of the grain offered in the market during the winter season ; when it is sometimes scarcely fit to be ground up at once, still less suited for storing away any length of time, or for shipment. This fact should not be forgotten by those who assert, from the want of being more practically informed, that barns are unnecessary to a farm under present circum- stances. The benefit derived from having, not one barn ARTIFICIAL DRYING OF WHEAT. 157 only, but several on most farms, is decidedly worth consi- deration. It is preferable to have two barns of moderate size, rather than one large one, for the purpose as much as possible of keeping the different kinds of grain separate, as well as the better disposal of the straw. Where the farm is large and hilly, as many are in this neighbourhood, a barn with a shedding attached is very advantageous for the purpose of consuming a certain quantity of straw by cattle near where it is grown, in which case the manure is more easily returned, thereby reducing the expenses of the farm. Another barn may be allotted to wheat, either filled with sheaves at harvest time, but I consider better suited for the purpose of putting the rakings into as they are col- lected at different times." 23. Artificial Drying of Wheat. — All practical au- thorities agree in stating that the desiderata named at the end of par. 2 1 are attainable at a small outlay of time or money by artificial drying. The advantages to be ob- tained from drying grain before being ground are thus summed up by a practical miller. " It will yield much more flour per bushel, and require about half the ma- chinery to manufacture it that it otherwise does if not dried. The quality of the flour is improved at least ten per cent., as by drying the wheat all impurities of a vege- table nature are entirely consumed ; and by extracting its natural moisture the flour will absorb, when baked, more water than it would before the grain was dried, which makes the bread much more palatable, it being more spongy." Any process, therefore, which enables the farmer to get the highest value for his crop, by preparing it ready in the highest condition for the merchant or miller, must be ad- vantageous in a pecuniary point of view. Corn drying then takes a wider range, and is valuable to a more widely extended class, than is generally supposed. A few remarks on some of the methods employed will therefore be of some utility. Speculative as the opinion may now be deemed, we be- lieve nevertheless that we shall yet see a very considerable 158 CULTURE OF FARM CROPS. development of the principle of using currents of air and of other drying means in the preservation of the valuable grain products of the farm. The principle is applied very extensively, and with remarkable success, in many branches of our own manufactures, and to materials not a whit more, if indeed so valuable as grain ; nor, new as the suggestion may seem to some of our readers to be, is it in reality so, for the importance of preserving grain has long been re- cognised, and it is many years since the first plan was pub- lished which proposed to effect it. In the year 1743 Dr. Stephen Hales published a work in which he described his ventilating machines and detailed their advantages for a variety of purposes ; amongst others, he endeavoured to prove their " great usefulness in preserv- ing all sorts of grain dry and sweet, and free from being destroyed by weevils both in granaries and ships, and also in drying corn, malt, hops, &c." That his plan was not chimerical appears from contemporary evidence of its use- fulness for these purposes. It consisted in forcing a quan- tity of air through the mass of grain, flour, &c., by means of his ventilators. It is unnecessary to describe how these are constructed, as these comparatively clumsy machines are now entirely superseded by the efficient fanners of the present day. It is, however, singular to notice that the other part of his plan presents a great similarity to a plan hereafter to be described. Dr. Hales carried a tube through the centre of the mass, perforated with holes to admit the air, which was forced into it to the surrounding mass. It appears that this plan was held in high esteem by the farmers of the day. A hollow reed or cane per- forated with two hundred holes was placed in the cen- tre of the sack, and a common bellows being attached to the tube by a leathern pipe, a quantity of air was forced into the tube. The plan was also adopted in France, for it appears by a statement in the Gentleman's Magazine, that M. de Humel de Monceau, a member of the Royal Academy of Sciences, " preserved a large heap of corn free from weevils for two years without turning, by merely ARTIFICIAL DRYING OF WHEAT. 159 blowing air through it." This principle of forcing air through masses of material to be preserved or dried is un- doubtedly a very valuable one, and deserves the attention of all agriculturists. The means by which its advantages can be obtained are so simple and inexpensive, that they cannot, or should not, stand in the way of realizing these advantages. We have no doubt whatever, from what we know of the astonishing power of currents of air, that it would pay, in every sense of the word, to provide a central opening to all stacks of every crop, and to force into — not through — these tubes a large quantity of air by means of a hand fan, or, still better, to work the fan by steam, and force the air through pipes leading through a steam chest or the upper part of a boiler, thus obtaining warmth and dry air. The outside of the pipes being surrounded with steam, the air forced through them in its way from the fanners to the stack would be soon raised to a sufficiently high temperature. But even where the plan of forcing air into the central opening in the stacks was not adopted, considerable advantage would still be gained from the open- ing or central tube alone. All that would be necessary in this case would be to have it, if solid, well perforated with apertures, and a free opening at top and bottom. To get the latter, the stack would require to be raised from the ground ; this, however, is done in all cases of improved stack construction. 24. As evidence of the extraordinary desiccating or dry- ing powers of currents of heated air passed through, or in contact with, various materials, we may here give some interesting results, for which we are indebted to Mr. Davison of London, who has devoted more time than any man living to this branch of engineering. The principle on which Mr. Davison's apparatus is conducted is simply forcing large bodies of air through a series of arched pipes heated by an ordinary furnace, and passing thus, at a high temperature, into the chamber containing the materials to be dried. The air is forced through the pipes by means of a fan. The process has been applied to the drying of al- 160 CULTURE OF FARM CROPS. most every species of material, the value of which is in- creased by being in a thoroughly dried condition. There seems to be an agreement on all sides that a drying appa- ratus of a good construction, forming a part of the perma- nent mechanism of the farm, would soon pay the cost of its construction by the increased value given to various crops by its use. We believe, indeed, the whole subject of the preservation of grain to be second to none of all the important objects which the enlightened farmer has in* view; nor the less so because at present it does not engage the attention of the general community, we believe that in time it will do so. We make, therefore, no apology for having directed the attention of the reader to a few of its leading points. And before concluding the subject we will draw attention very briefly to the modes in use of obtain- ing and applying a supply of warmed air by using steam or hot water. There are two ways in which grain, &c., may be dried by the application of currents of warmed air — namely, first, allowing the air to pass over heated sur- faces, and thereafter to find its way through the mass to be warmed — and, secondly, warming large bodies of air by a special apparatus, and forcing these into the chamber in which the material to be dried is placed. No matter which of these two modes is adopted, the great aim is to have the largest supply possible of heated air with the smallest extent of heating surface. Not the least advan- tage of a fixed steam engine on the farm is the facility with which a supply of steam can be obtained, not only for cooking but for drying purposes. Let us briefly describe some of the modes by which either the waste steam of the engine or a special supply of it can be used to the warming of large bodies of air. 25. The usual way to use steam for heating the interior of a building is to pass it from the boiler to a pipe which is led round the apartment in which the wheat is to be dried. This is placed either on standards near the wall, or within a conduit or open drain beneath the flooring, this being covered with open grating, through which the heated ARTIFICIAL DRYING OF WHEAT. 161 air ascends. When this latter method is adopted it is of course necessary to supply the conduit in which the pipes are placed with fresh air. The pipes should be inclined to the boiler, so that the water of condensation may easily be taken back to it. Where the return pipe is taken back to the boiler, returning the steam and condensed water to the boiler after the circuit is completed, a somewhat compli- cated arrangement of "trap" or valve is required. To ob- viate the use of this, it will be the simplest way, if not the best, to allow the steam to pass from the pipe into the open air after it has made its circuit, and to have a pipe with stop-cock attached at the same place for leading the water of condensation to a small tank, or to the ordinary drain attached to the building. The diagram below illustrates one mode of arranging the steam pipes in a drying cham- ber; a a the flooring beams on which the material to be dried is placed ; b b the steam pipes. It is obvious that in all cases where a steam (fixed) engine is employed on the farm steading, the waste steam may be employed in the above fashion. Nor would it be useless to have a ho- rizontal rack, as a a on the above figure, above the boiler on which to dry corn in the sheaf. In place of using pipes as now described, a very much larger extent of heating is obtained by using Fig. 20. I I I I I O O b 162 CULTURE OF FARM CROPS. flat receptacles, the surface of which is provided with ribs or flat projections, (see illustration, fig. 20). These "become heated by contact, and the result is that each rib becomes a heating surface. By far the most compact, as probably it is the most efficient, heating surface is the " heat-box," of Mr. Walker of Manchester (see fig. 21). This is made Fig. 21. up of a series of blocks of cast-iron. Each block contains a number of square cells or tubes ; both sides of the divisions between the cells forming effective heating surfaces. These blocks, usually six in number, are placed within a hollow case, of an ornamental form, standing within a few inches of the ground. Steam or hot water is supplied to the space surrounding the case, and the heat is communicated to the blocks. The air passing up the interior of the cells be- comes mildly heated, its place being supplied and a contin- ous current maintained through any fresh air flue over the mouth of which the set of blocks may be fixed. The blocks and their case — for the case itself forms a heating medium — which may be denominated the honeycomb or cellular ar- rangement, will present more heating surface to the air than can be obtained within a given space by any other form. ARTIFICIAL DRYING OF WHEAT. 163 The remarkable aggregation of heating power thus attained in a small space will be best understood when it is stated that, in a heat-box measuring 27 inches long, 18 inches wide and 16 inches high, 80 effective feet of heating sur- face are collected. We have already explained the furnace system by which Mr. Davison warms large volumes of air; that gentleman has recently introduced an exceedingly compact form of heating apparatus to be used in conjunction with a fan. This may be described briefly as a fanner surrounded by a series of convolutions ; these are double, and are filled with steam. The fanner draws air in at the centre, and drives it outwards towards the periphery, and as it winds round and round the convolutions it gets rapidly heated. Each convolution being made up of a double plate, two surfaces are obtained, the inside and outside (see fig. 22). A brief glance at the hot water heating apparatus will suf- fice for our purpose. When heat is applied to a vessel of water, as the particles of water at the bottom get heated they rise up towards the top, while other and colder parti- cles descend to take their place, and getting in their turn heated, rise to give place to colder particles. This con- stant circulation is maintained till the mass is of a uniform temperature; but if the vessel, which we shall suppose a tube, is elongated, and a great portion of its length exposed to the atmosphere, which will rob it of its heat, this uni- formity of temperature will seldom be attained, so that a continual circulation of the particles of water will take place in the tube so long as heat is applied to its lower extre- mity. This is what happens in the hot water apparatus. This arrangement is called the low-pressure apparatus, in which the temperature cannot possibly get above the boil- ing point — practically, it is far below this. 26. As closely connected with the subject of drying grain described, and as indicative of the mode of carrying it out, we translate the following from a Continental journal : — The Attention to be given to Gram in Granaries. — "The frequent rains which have taken place during the month of 164 CULTURE OF FARM CROPS. Fig. 22. August, in the north and in the centre of France, have been a great obstacle to the harvest; much grain has been taken in before being completely dry ; the ears were still swollen with the dampness, a dampness which they retain for a long time, even in the granaries. This grain, laid in heaps, will ferment and acquire a bad taste, and favour the increase of charengons and other insects if it is not often removed. 'Le Nouvelle Agricole de Montdidier,' for the year 1858, shows a way for preserving it much better than the removal of the grain. This process consists in produc- ing currents of air in the heaps by means of earthen pipes RECEPTACLES FOR STORING WHEAT. 165 going from the interior to the outside. In order to per- form this process I used drainage pipes of Om 035 in diameter, in price 25 francs a thousand. As these drain- age pipes are only Om> 35 in length, I caused some to be made double that size, which were pierced with a number of small holes. These pipes do not cost more than 6 francs a hundred. The process of which I speak being as yet little known, it would be very difficult to find pipes similar to those which I use. Persons wishing to procure them would do well to order them beforehand, before winter. When this process is better known, as it cannot fail to be at some time, it is not unlikely that tile-makers will con- struct pipes for the purpose." 27. Storing up of Wheat, Receptacles for. — On the sup- position that we have got our wheat in good sound condition, the next question is, how can it be preserved 1 We may make it dry, but can we keep it so 1 or we may put it in only partially dry, can we make it while there, wholly, or nearly so 1 or we may put in a portion damp or wet, can we prevent this from influencing the portion that is already sound ? These are questions, the answer to which will in- volve some details that may be considered interesting as well as useful. We shall direct attention in the meantime to the last of these. 28. It has always appeared to us an interesting problem, whether there could be some means devised for preventing the spread of disease or unsoundness in collections of grain without involving either much manual labour or expensive constructions. The patent granted to Edward Larudant Bellford professes to give a solution of this problem. The means by which he does so are exceedingly simple, and are based on the following theory : — " In vegetable substances, which contain only a small quantity of moisture, the pro- cess of decay always, or almost invariably, commences at the centre of the mass, and from thence extends in all di- rections. It is well known to millers and others engaged in the manufacture, storage, or transportation of flour, meal, and grain, that in those substances such is the case, the 166 CULTURE OF FARM CROPS. centre being frequently found soured and heated highly, while those portions near the outside of the mass are un- injured. It is also the case in hay or other substances of a similar nature." Such, then, is the theory ; the practical method of obviating the evil deduced from thence is very simple. Take out the centre mass, or insert a tube or series of tubes in the centre of the receptacle in which the flour &c., is contained, and the difficulty is met. What the con- sequence of this simple contrivance is, a brief investigation will show. Suppose a barrel of dry sponges, having in the centre thereof a series of sponges saturated with moisture extending from top to bottom of the barrel, there will thus be a core of wet in the midst of the dry sponges. Accord- ing to the theory above noted, the wet will radiate from the centre mass outwards in all directions, and the sur- rounding mass will become gradually saturated. As there is no obstacle in any direction to these radiations of wet, we can suppose the process to go on by adding a series of concentric rings of wet progressing towards the external barrel. It is riot at all likely that the wet will progress only on one side of the wet central mass, thus forming one semicircle of wet and another semicircle of dry sponge ; it is just as natural for the wet to go to one side as to the other, and seeing that there are no obstacles to its doing so, the almost absolute certainty is that it will go to all sides. In the centre of the barrel place a tube ; the consequence is, that the wet mass is displaced to one side only, and be- fore the damp or unsoundness can reach to the opposite side of the tube and the material there placed, it must per- force travel round the whole circumference of the tube. But to travel in this way the wet must progress in a lateral direction, and we have already shown that it radiates from a point like the spokes of a wheel ; its progress, therefore, will be mainly outward towards the barrel. By this ar- rangement, therefore, only a minimum portion of the mass is damped, and the chances are that before all the mass round the central tube gets damp — which must necessarily be a slow process, as each damp portion will only, like its KECEPTACLES FOR STORING WHEAT. 167 neighbour, radiate from its centre — the flour or grain will be dislodged from the receptacle. Without the central tube any wet mass is free to radiate in all directions, with the tube a large proportion of these rays are arrested by the tube, and these left free to go amongst the mass pene- trate only in the line of the moist portion. Were damp or wet the only evil to be arrested, it would not be so im- portant a matter to prevent it, as, on the supposition that only a small portion was admitted damp, by communi- cating itself to others it would be so divided that in each it would be almost inappreciable. But wet brings decay, and decay "grows by what it feeds on;" it progresses steadily to a consummation. It may be compared to gan- grene in the animal body, — it must be lopped off, to be got rid of ; it cannot be brought to a healthy state itself, it must only be prevented from contaminating the surrounding por- tions. The invention, when applied to barrels for trans- portation, is more particularly meant for Indian corn meal and wheat flour. The following are some data which may serve as guides to those who may use the plan : — For a barrel of wheat flour of the usual size, containing about 196 pounds, for a voyage of about a month or six weeks, a tube of 2 inches will be sufficient, and one of 2<| inches for a six months' voyage. As, however, Indian corn meal is much more liable to decay than wheat flour, it is desirable that a tube of 7 inches diameter for a six months', and one of 5 inches for a six weeks' voyage be provided. The plan is also applicable to corn bins and corn stacks. In the latter, the central opening is recommended to be made by means of poles, an opening being made at top and bottom of the central tube to admit of ventilation. Whether the theory on which the plan is based is cor- rect or not, there can be no doubt that the spread of decay in the mass of flour, &c., will be materially prevented by the placing of a tube or cylindrical body in its centre ; even although the decay does not progress radically as suggested, the effects of contact will be materially lessened. But as to the great advantages attendant upon the plan, when 168 CULTURE OF FARM CROPS. made subservient to the plan of drying wheat by passing currents of air through it, there can be no doubt. 29. Grain Tanks. — The usual mode of keeping grain is, as our readers know, on the floors of granaries. This mode is open to very grave objections, which are obvious enough on consideration; to obviate these Mr. Bridges Adams has proposed to use underground tanks of wrought-iron, Of of these we give here Mr. Adams' own description : — " There does not seem to be any difficulty in the matter, if we can divest ourselves of preconceived ideas of the no- tion that a granary or grain receptacle must necessarily be a building with a floor or windows more or less multiplied in altitude. We may reason by analogy as to what is the cheapest and most effective means of securing perishable commodities from the action of the atmosphere and vermin. In England we put our flour in sacks. Brother Jonathan puts his in barrels, which does not thoroughly answer. If Brother Jonathan wishes really to preserve his flour or his ' crackers ' undamaged, he makes them thoroughly dry and cool, and hermetically seals them in tin cans. This also is a common process to prevent goods being damaged at sea. The Chinese, not having much facility for metal manufacture, line wooden chests with thin sheet-lead or tin, and pack their teas in them. In Eng- land we keep our tea and sugar in cases of tinned sheet- iron. We preserve meat in tinned cases, hermetically sealed. We put fruit into sealed bottles. In all these cases the object is to exclude the air as well as vermin. . . There can be no doubt that if we were to put dry wheat in a hermetically sealed tinned case, it might be kept as long as the famed ' mummy wheat ' of Egypt. This will readily be admitted, but the expense would be queried. Let us examine into this. A canister is a metallic reser- voir ; so is a gasometer ; so is an iron water-tank in a ship, at a railway station, or elsewhere; and a cubic foot of water-tank on a large scale will be found to cost very much less than a cubic foot of canister on a small scale. And if a bushel of wheat be more valuable than a bushel of GRAIN TANKS. 169 water, it will clearly pay to put wheat into huge canisters of iron. The wheat canister, in short, should be a wrought or cast iron tank of greater or less size, according to the wants of the owner, whether for the farmer's crop or the grain-merchant's stock. This tank should be constructed of small parts, connected together by screw bolts, and con- sequently easily transported from place to place. The in- ternal parts should be galvanised, to prevent rust, and the external parts also, if desired. It should be hermetically tight at all the joints, and the only opening should be what is called a man-hole — that is to say, a canister top where the lid goes on, large enough to admit a man. When filled with grain, the top should be put on, the fitting of the edge forming an air-tight joint. Wheat put dry into such a vessel, and without any vermin, would remain wheat any number of years. But an additional advantage to such a reservoir would be an air-pump, by the application of which, for the purpose of exhaustion, any casual vermin would be killed. If the grain were moist, the same air- pump might be used to draw or force a current of warm air through it, to carry off the moisture. By this process, and subsequently keeping out the air, the grain might be pre- served for any length of time. As the reservoir would be perfectly air-tight and water-tight, it might be buried in the ground with perfect safety ; and thus cellars might be rendered available for granaries, economising space of com- paratively little value. The grain would be easily poured in from the surface, and to discharge it an Archimedean screw should be used. The size of the reservoir should be proportioned to the locality, and it should hold a specified number of quarters, so as to serve as a measure of quantity, and prevent the expense of meterage. ... If con- structed above the ground, a stair or ladder must commu- nicate with the upper part, and the lower part must be formed like a hopper for the purpose of discharge. For many farm localities this arrangement might be best, and wheat might be thrashed into grain direct from the field, and stored. . . . Granaries of this description would 170 CULTURE OF FARM CROPS. occupy less than one-third the cubic space of those of the ordinary description, and their cost would be less than one- fifth. . . . With this security for storing safely, a farmer would have less hesitation in sowing great breadths of land. He would not be driven to market under an average value, and might choose his own time for selling. The fear of loss being dispelled, people would buy with less hesitation, and the great food-stores of the community would, by wholesome competition, insure the great mass of the community against a short supply. But as long as uncertainty shall prevail in the storage of grain, so long will it be a perilous trade to those engaged in it, and so long will the food of the community be subject to a very- irregular fluctuation of prices. There is nothing difficult in this proposition. It is merely applying existing arrange- ments to unusual cases. There needs but the practical ex- ample to be set by influential people, and the great mass will travel in the same tract. To the wealthy agriculturist it will be but the amplification of the principle of the tin- lined corn-bin, that keeps out the rats from the oats of the stable. . . . Were this mode of preserving grain to become general, the facility of ascertaining stocks and crops after reaping would be very great. The granaries being measures of quantity, no hand -measuring would be needed, and the effects of wet harvest weather might be obviated." 30. For Storing up Corn or Grain. — The invention of M. E. Mile Pasy, of Canton Neuvy le Eoi, France, may be noticed now. The form of granary which the inventor pre- fers is that of large vertical reservoirs of a cylindrical form placed together like the pipes of an organ, and placed on a platform, beneath which is placed a winnowing machine. From the winnowing machine the dressed corn is taken up by a series of small buckets fixed to an endless strap, which works in the spaces left between the cylindrical tubes. The corn is delivered to a central reservoir, from whence it is passed into the interior of the cylinders in which the corn is to be stored. The cylinders are of wider dimensions at the bottom than at the top, and all terminate in a funnel THE CONSTRUCTION OF GRANARIES. 171 so that they may be completely emptied when it is de- sired to remove the corn from one cylinder to the other, or to pass it through the winnowing machine, or to send it to market. The preservation of the grain rests principally upon a powerful ventilation, which can be repeated eight or ten times a-year. By means of a gauge the contents are easily read off. Beneath the platform upon which the cy- linders stand may be placed crushing or flour mills, which can be supplied directly from the vessels above. 31. A very complete system of arranging and construct- ing granaries for the storing up of grain and preserving it in good condition during its period of storage, has been introduced by M. L. J. Gustave de Coninck, of Paris, of which the following is a description : — " The system con- sists in building the different floors of a granary in a square or rectangular form with joists, on which the planks are placed crosswise in such a position as to form hollows be- tween each, thus presenting alternate crests and hollows. These planks, not being joined, leave between them on the crests and in the hollows spaces or grooves, partly closed by small pieces of wood, which are cut slantingly in order to facilitate the running of the grain from one floor to that beneath by the openings. The number of openings varies for each floor, and is as much larger, and the running of the grain consequently as much more rapid as the floors are nearer to the base of the granary. Under each floor, and consequently at the upper part of each stage, are openings covered with metallic cloth, which give access to the air. If a quantity of grain is taken from the lowest floor equal in volume to that in one stage, an empty space is formed, into which the cereals run from the floor above ; but, as there are more openings in that floor than in the one above it, the flowing takes place more rapidly, and thus leaves an empty space into which the air enters by means of the openings. This effect is produced in each stage succes- sively, and is said to be quite self-acting ; thus the grains contained in each compartment pass from one floor to the next, falling through the atmospheric air existing between 172 CULTURE OF FARM CROPS. each floor and that above it. The only labour to be per- formed in connection with the above operation is to raise, by means of an endless cup chain or otherwise, the grain abstracted to the uppermost stage of the granary, the quan- tity of which may be one-sixth, one-fifth, or one-fourth, as the granary is composed of 4, 5, or 6 floors. " In the operations above described, the grains, in their descent, occupying successively all the different stages be- tween the summit and the base of the granary, are, there- fore, by means of the friction, without pressure of the grains against each other, cleansed from all foreign matters, dust, and impurities which otherwise adhere to their sur- face, but in this case escape by the perforated openings in the upper part of each stage. The general movement thus given to the whole mass of grain is also a great protection against the insects. As a completion of this system one or more wire lattices may be placed above the uppermost stage of the granary, forming sieves on which the grain may be, in the first place thrown, and which would retain all such extraneous matters, as pieces of straw, &c., which might be intermixed. For aerating the grain when at rest, if required, by causing it to be traversed by currents of air, some planks of about 8 inches in width may be placed across the granary, and the walls under their extremities may be pierced, thus giving admission to the air; the grain in meeting with these planks falls on each side, leaving an empty space beneath, of which the section would be that of a triangle, the horizontal side being formed by the plank and the others by those of the heaps formed by the grain. For augmenting the ventilation a tube may be made the whole height of the granary, to be fed by means of a powerful ventilator at the base, and connected at each stage with a smaller tube pierced with small holes and placed on the floor. This system of construction may be employed for a stove for drying grain by means of hot air. In this case the apparatus should be constructed in iron, the floors should be closer one to the other, and supposing a section to measure 9 ft. by 9 ft., the distance between the floors THE CONSTRUCTION OF GRANARIES. 173 should be about 3 ft., and the walls should be plain. A tube in sheet iron or brass of about 4 in. in diameter or more, covered by a larger tube, leaving a space between the two intended to receive a current of vapour, is placed, ver- tically, the height of the compartments of the granary, with which it communicates by means of branch tubes, the ends of which are partially open to the air. The air being dri- ven through by a ventilator, becomes heated in passing, and penetrates to the upper part of each stage, leaving by the small tubes at each stage. This air, the temperature of which may be more or less elevated, and which thus circu- lates during the working of the apparatus, dries the grain completely. The approaching of the floors in this modi- fied system allows of two similar apparatuses being placed one above the other, separated by a floor, the openings of which may be shut by means of rods placed for the purpose, so that when the two apparatuses are full, the openings of the floor are shut. The lower apparatus may thus work alone, and when its upper compartment is empty, communi- cation may be re-established between the two by turning the rods." APPENDICES. ON the point alluded to in par. 5, p. 94, namely, the effect of frost upon wheat ; a very interesting and practical dis- cussion was recently gone through in the pages of a lead- ing Agricultural Journal. The discussion was opened up by a writer who drew the attention of those engaged in farming to the very great — and as he put it — the most alarming injury which was being done to the wheat plants by the severe frost then prevailing, and which, in his es- timation, was likely to result in the destruction of a large proportion of the crop. This called forth sundry opinions of other writers, amongst others the writer upon agricul- tural subjects well known under the nom de plume of the " Old Norfolk Farmer ; " who thus very decidedly expressed his opinion that wheat was not destroyed by frost. " / do not believe there ever was a plant of ivheat de- stroyed by frost in the United Kingdom. I have known whole fields destroyed by the root-fall after a long and se- vere frost; but this was owing to the neglect of the far- mers in not rolling the wheat, or driving a flock of sheep over the field, as soon as the frost gave way, in order to close the soil round the roots. The rationale of this operation is as follows : — The rains of autumn and winter swell the soil, and the late-sown wheats, not having ac- quired much hold on the ground, are raised with it; then comes the frost, and evaporates the moisture from the soil, which, when the thaw commences, falls from the roots, leaving them exposed to the sharp and strong winds of EFFECT OF FROST UPON WHEAT. 175 March, which blow away the remainder of the soil from them, and the plant dies, not a natural death, but one through neglect on the part of the farmer — first, in not getting his wheat in early enough ; and, secondly, in not afterwards taking the precaution of closing the soil to the roots of the plant when the frost was over." This view was corroborated by other writers who followed upon its publication, the remarks of one of which we can only here find room for : — " I quite agree with the * Old Norfolk Farmer ' that winter frosts lift up the wheat plants, and, if not rolled early in spring, are greatly damaged by the evaporating days and frosty nights of March and April. It is only re- quisite for any farmer, especially those occupying light- land farms, to walk across his young growing wheat after the last little winter has passed away, and he will observe the rootlets of thousands of plants neither in nor out of the soil, and in such a state to cause the rootlets to wither under the influence of frosty nights and sunny days, unless replanted with a heavy iron roller (Cambridge roller I pre- fer), applied at the very first opportunity in spring, at a time when the soil will print, and not too dry as to be dusty. " I rolled a very thin flat of wheat on the 4th of April last ; I likewise took the precaution, and' rolled the whole of my young seeds, as they suffer each year throughout the country, more or less, from the like cause as wheat, and I can assure you I am being amply repaid for the trouble, as my seed-pastures are looking well; whereas my neigh- bours' look as badly, for want of attending to this impor- tant means of rolling in early spring. Science applied to agriculture will achieve much, but practice will frequently beat science in some seasons. In every winter I have found that the mechanical treading of sheep, in wet weather, upon light land (chalk), plays a most important effect upon the following crops, provided the land be ploughed up and harrowed before it becomes too much dried in spring. Chalk soils, with turnips which have been eaten off with sheep when it has either been covered with snow or har- 176 CULTURE OF FARM CROPS. dened by frost, is less trampled or consolidated; hence, when ploughed, it is loose, and very seldom grows so bulky a crop as when well trodden in soft weather. It almost appears that, on one hand, the manure of sheep, in the form of dung and urine, is trodden and incorporated in the soil ; on the other hand, it is deposited on the very surface, ex- posed to the atmosphere, and so the very essence drenched away with the rain. "Are there not many farmers who cannot remember their fed-oif turnip-fields presenting, whilst growing a crop of corn, an uneven resemblance — that is, some folds ap- pearing better than the rest, and at harvest turning off al- most double the quantity of sheaves than other parts ? Yet the turnip-crop was the same, and the same number of sheep kept thereon ; but the weather was not the same, so that the sheep could not act with that mechanical effect and benefit upon the soil. It is likewise worthy of re- mark that in autumn, when the land is ploughed for wheat, so that the soil will tread firmly under the horses' feet, the wheat will withstand the winter better than when it is put into the ground in a loose and dry bed of the chalk formation." It is right, however, to state that the view maintained in the above — and which is probably that of nine-tenths of the practical farmers of the kingdom — was not concurred in by other writers who took part in the discussion, one of whom took special objection to the roller as being at all likely to be useful in land totally unfitted to receive a horse, let alone a heavy roller, on its adhesive cloggy sur- face; a condition of land which is too often met with in the winter and spring months in this country. B. It has been a subject of frequent remark that, notwith- standing all our advance in the theory or what may be called the science of agriculture, the details of our practice stands very much at the point it stood at many years ago. So much truth is there in this, that a very able and acute CAUSES OF BUST IN WHEAT. 177 authority on farming has stated, that, as the result of a very wide and varied research into the books published many years ago on farming, he believes that, with the addition of a few, comparatively few, paragraphs or pages, the whole might be published now as trustworthy guides to modern practice. Of course the same remark does not apply to the theory or science of agriculture; and although some may even object to the statement above made that it applies so closely to the practice, still there can be no doubt that, embalmed in the pages of old works, lies many a pregnant truth, many a suggestive fact or hint ; and of the truth of this we ourselves have had some experience. In view of this it has appeared to us that we may serve some indi- rectly suggestive, if not directly practical, purpose, by giv- ing here an extract from a work published many years ago, upon the causes of rust in wheat, as supplementary to what we have said about it in the body of the work, (see par. 8, p. 100). On the subject of rust in wheat and its causes, the fol- lowing by Mr. Hayward in his " Science of Agriculture," written may years ago, will be useful : — " I shall take leave," says the writer, " to state that the observation and experience of many years have convinced me, that the opinions of the great reformer of the medical profession, Mr. Abernethy — that the most afflicting diseases to which the human species are subjected, are generated in the stomach, and consequently are to be remedied by the sto- mach— are perfectly just and well founded; and I am also convinced, that most of the diseases of animals and of plants may be accounted for and remedied on the same principles. From what has been said, it is clear that ve- getables cannot 'be supported without a due supply of food ; and that with those, as with animals, the quality and quantity of food must possess an equal influence. " Every man is aware that the quality of the food he consumes is equally as determined in its eifects as the quantity ; and such, no doubt, is the case with plants, as 1' "i fore observed. When an animal is constrained to live 178 CULTURE OF FAEM CROPS. on meagre, impure food, it is induced to consume a greater quantity, to make up as much as possible for the deficiency of quality ; and the consequence is, a distension of the stomach and bowels, and this is often followed by a po- verty and corruption of the fluids, which produces disease and debility; and the body is wasted by eruptions, and becomes a prey to vermin. And when an animal (more particularly during parturition) is glutted with grass and rich food, a surfeit is the consequence, and it is subjected to a stagnation of the fluids, inflammations, and eruptions, which often end in mortification and death ; and plants, under the same circumstances, are subject to the same consequences. " These observations will be found correctly to apply to, and to afford a clear exemplification of, the rust, or black blight in wheat. "On this subject Sir John Sinclair says, 'It appears, from an able paper written by a distinguished naturalist (Sir James Banks), that this disease is occasioned by the growth of minute parasitical fungus or mushrooms on the leaves, stems, and glumes, or chaff of the living plants; and that the roots of the fungus, intercepting the sap in- tended by nature for the nutriment of the grain, render the grain lean and shrivelled, and, in some cases, rob it completely of its flour. JN"or is that all ; the straw becomes black and rotten, unfit for fodder, or little better than a caput mortuum, possessing neither strength nor sub- stance.' " Again, — ' Several of the accidents above enumerated may contribute to the production of rust ; but there are two additional circumstances which likewise tend to pro- mote it. First, — Having the land in too rich a state for corn crops, and, secondly, — when too frequent a repetition of crops of wheat takes place.' " It has been well observed, that when crops intended to ripen their seed are objects of culture, there is not only wanted a degree of vigour and luxuriance in the plants sufficient for the purpose, but if the fertility of the soil be CAUSES OF RUST IN WHEAT. 179 raised to a higher pitch than is necessary or consistent with that object, injurious rather than beneficial consequences may be the result. Land may be too rich for corn crops ; and it is better to keep it in a well balanced condition, or in a medium state of productiveness, than in too fertile a state. The greater quantity of sap and juices in vegeta- bles growing on highly cultivated lands, it is evident, must necessarily render them more susceptible of the effects of sudden and extreme changes, and consequently more liable to disease. Besides, as mushrooms are produced on beds of dung, great quantities of manure must promote the growth of fungi or parasitical plants, on the crops of wheat, if they are once infected. The wheat produced on the site of a dunghill is always rusted, even in the most favour- able seasons : and if the whole field is a species of dung- hill, how can it escape ? " A too frequent repetition of crops of wheat, more espe- cially when accompanied by great quantities of manure to force a crop, will often have the same effect. The rust was but little known in the western or the northern parts of England, or the southern counties of Scotland, until of late years, when every exertion has been made to in- crease the quantity of that grain." Sir John Sinclair also says, " Among the remedies likely to diminish the effects of this fatal malady, the following have been particularly recommended : — 1, Cultivating hardy sorts of wheat ; 2, early sowing ; 3, raising early varieties ; 4, thick sowing ; 5, changes of seed ; 6, consolidating the soil after sowing ; 7, using saline manures ; 8, improving the course of crops ; 9, extirpating all plants that are re- ceptacles of rust ; and 10, protecting the ears and roots of wheat by rye, tares, and other crops." And again, he says, " It is likewise stated on the re- spectable authority of an eminent naturalist (J. A. Knight. Esq.), that by crossing different varieties of wheat, a new sort MAY be produced, which will completely escape being rusted, though the crop in the neighbourhood and in al- most every district in the kingdom may suffer from it in 180 CULTURE OF FARM CROPS. the same year. These circumstances tend to prove that the rust does not depend solely on atmospheric influence, otherwise it could not be prevented by changes of seed or by the crossing of different varieties." This theory of Mr. Knight's is, like many others of his, grounded on a superficial view of things, and is a mere fallacious hypothesis. Indeed all these great naturalists appear to have be- wildered themselves in specious theory ; and from not hav- ing traced the operations of nature to its source, have throughout mistaken the effect for the cause. Suppose a farmer was to find a sheep, unhappily reduced and preyed upon by maggots or the larva of the flesh fly, he may very justly suppose that the maggots reduced the sheep ; and as justly expect, that whatever sheep were sub- jected to the maggots would be reduced in the same man- ner. Then what would be the best and proper remedy ? Knowing the maggots to be produced from eggs deposited by flies, would he try to cover his sheep from the flies ; or attempt to drive them where there were no flies ? Where is the farmer or shepherd that does not know that flesh flies will not deposit their eggs on a healthy part of a sheep ; or if they do, that they will not produce maggots ? They know full well, that if a sheep be diseased by eruptions or wounded, the flies will find out these places, and there de- posit their eggs ; and, therefore, the remedy is simple. Cure and prevent the disease, or protect the wounds, and the evil is avoided. " Eemove the cause, and the effect ceases." Very similar will be found the diseases in wheat, called the rust or black blight, and its cause. The fungus undoubtedly preys upon that which is in- tended to nourish and sustain the wheat ; but what afforded an attraction and lodgment for the fungus ? This is the grand question. It is stated, that the fungus is a parasitical plant, like the misletoe, but this is not the fact ; the fungus has no power to attach itself to, or penetrate, the healthy stalks of CAUSES OF RUST IN WHEAT. 181 the wheat any more than the larvae of the flesh fly have the healthy skin of the sheep. Any one who will examine the stalks of wheat growing on a luxuriant, rank soil, at short intervals, about the time of its first showing the swelling of the ear, will perceive the vessels to become ruptured, either from the luxuriant flow of the sap up the tender tops of the plants, being checked by cold winds, or an unhealthy overfulness, or some other casual obstruction, and the sap being thus sud- denly checked will rupture the vessels and ooze out through little slits or longitudinal fissures ; the discharged matter will soon assume the appearance of a white jelly as it dries, it will become yellow, and then brown, and of a hard tex- ture; and in proportion as the sap-vessels are injured and destroyed, and this exudation takes place, the plant must of course, more or less, fail in its supply of nourishment to the grain. In some cases, the strongest stalks will not be able to push the ear beyond the leaf, and the corn conse- quently will be starved. Whilst the season continues dry and cold the exuded sap will remain like dry gum, but as it advances, and the weather becomes warm and moist, the gum becomes moist, soft, and putrefying, and then forms and affords a nutritive bed for the mould or fungus, which grows and increases until it is deprived of moisture, or is so reduced as to be insufficient to sustain it, when it dies ; and according as the season is favourable or unfavourable to its growth, it produces a brown or black powdery sub- stance in a proportional quantity. Thus, then, the founda- tion or cause of the rust or fungus is the putrefying matter discharged from the ruptured sap-vessels of the plant ; and although the ruptures may be occasioned by a contraction or obstruction of the vessels by atmospheric influence, the overfulness or over-luxuriance of the plant produced by surfeit, or the being glutted with rank and unwholesome food, and its incapacity of digestion and unhealthy ob- structions renders it more liable to such injuries, and may therefore be considered as the general cause of the disease, blight, or rust. 182 CULTURE OF FARM CROPS. I have planted wheat in a rank compost of dung, which from its first appearance in the autumn, during its growth in the winter, and in the spring, maintained excessive lux- uriance, but which was ultimately so reduced by rust as to be rendered weak and incapable of bringing its seed to perfection ; at the same time, and close alongside, I also planted wheat in a pure and sweet sand, and supplied it with a solution or infusion of rotten dung, by way of food. This never appeared half so luxuriant as the other, but the stalks or straw grew perfectly healthy and free from disease, and the grain was of good quality. The following statement by Sir John Sinclair, as well as what has been already quoted, will in every respect be found to corroborate and sustain my observations and opinions. He says, "As land in too rich a state is apt to produce rust, it is found to be an effectual remedy, if, previous to a crop of wheat, the dung is applied to a smothering crop, as tares, hemp, &c. Indeed, after cole-seed, wheat is scarcely ever known to be rusted. The general culture of that arti- cle, and the use of Dutch ashes impregnated with saline matter, tends greatly to the exemption from rust by which wheat in Flanders is distinguished. " Potatoes, when the crop is large, have the same effect ; in Flanders, where the wheat is never materially injured by rust, potatoes are considered, in its best cultivated dis- trict (the Pays de Waes), as the best preparation for that crop. If too much dung occasion the propagation of fungi, which there is reason to believe is the case, smothering crops, by exhausting and diminishing the strength of the dung, may take away that tendency." Undoubtedly the tares, cole-seed, potatoes, &c., growing on the manured soil, must reduce, if not wholly consume, its gross and over-luxuriant qualities, and time and expo- sure effect a more complete decomposition and evolution of its vitiating effluvia, and thus the great cause being re- moved, the effect must cease. Sir John further says, "Mr. Knight is decidedly of CAUSES OF RUST IN WHEAT. 183 opinion that the disease is taken up by the root, every ex- periment to communicate it from infected straw to others proving abortive, and, indeed, if it were introduced into the ear of the plant, how could it descend, and infect solely the stem, which is the case, unless when the disease is in- veterate ]" As to the fungus passing into plants by the roots, or being prevented from propagating by any of the means here pointed out, it appears almost too preposterous to be seriously thought of. How difficult do our housewives find it to exclude the seeds or prevent the fungus growing on their pickles and preserves, even by tied down bladders and tight corks'? And if horse dung in a mass be placed in certain situations, it is well known that even the large edible mushrooms will rise and grow where they never were seen before. Thus, then, if the cause of the rust or black blight be as I have stated, — and the observations both of Sir John Sinclair and Mr. Knight confirm my opinions, and the ob- servations of Sir Joseph Banks do not controvert them — the remedy is simple and obvious; viz., for the production of seed crops, let manuring follow and not immediately precede them ; or, at any rate, dung should not be ploughed in on such lands, immediately before sowing the seeds. And it is equally obvious that the ploughing in green crops must be conducive to the production of rust. And the feeding off turnips with sheep, or folding them on the land, immediately before sowing, must have a strong tendency to the same effect. If, when lands are manured, two or three succulent or green crops be taken off before it is sown for seed crops, although the leaf and plant, or straw or haulm of such crops may not appear so luxuriant in consequence, the seed will be larger in quantity, and finer in quality. And if, in the general course of cultivation, dung be applied or given to the green crops, the luxuriance of leaf, stalk, &c., will be produced in that form which is most valuable, either as green food, turnips, &c., or hay; and the succeeding grain 184 CULTURE OF FARM CROPS. crops would in no respect be diminished, and the straw, being free from disease, would be much increased in value. " From what I have stated, if two crops of wheat be de- sired in four years, the better mode of manuring for them is to lay on the dung the first two years for green crops, and take the two wheat crops following in the last two years. There never was a more widely mistaken notion than that a supply of dung given one year can be exhausted either in that or the following year by cropping with any thing ; but by burying it below reach of the roots, or so low that it becomes inert or poisonous, the manure may be worse than lost." Sir John Sinclair again very justly observes, " By the improvements which may be effected by the observations of ingenious naturalists, and the experience of intelligent farmers, there is every reason to hope that the diseases of wheat may, in a great measure, be so mitigated in their ef- fects that they will not in future be felt as a national ca- lamity. For that purpose, however, it is necessary that the diligent farmer should seize every opportunity of improv- ing his knowledge in the diseases of wheat; should note down all the circumstances connected with the subject as they occur, and should compare his observations with those of others ; that, whether the causes of rust are general or local, they may as much as possible be obviated." To this I will beg leave to add that, however repeat- edly the diligent farmer may have been misled by theory, he cannot be justified in wholly opposing or neglecting science. The opinions I have here endeavoured to ex- plain are grounded on demonstrative practical experiment. And as it is in the power of every farmer to make the same demonstration, I trust every one will consider it in justice, due from all to do so, before they indulge in speak- ing lightly of them, or in treating them with neglect.

OF the cereal or white crops of the farm, barley claims the place next in importance to the wheat ; to the leading features connected with its cultivation we there- fore proceed to direct the attention of the reader. In hunting up such scanty records as the generally meagre history of agriculture affords bearing on the early history of our farm crops, we find but little, and that little vague and uncertain, with reference to that of barley. As in the case of wheat, that all is merely conjecture as to its origin, or by whom it was first introduced. The writings both of profane and sacred authors abound with allusions to it, showing the important place it occupied and the estima- tion in which it was early held. The Eomans held it in high repute, and the Greeks especially so ; but it is to the writings of the former people that we owe what we know N 186 CULTURE OF FARM CROPS. as to its habits, and the modes adopted for its culture in ancient times. The most marked general feature connected with barley is the wide, range of climates in which it can be cultivated, in this respect taking precedence of all our cereal crops, for it can be cultivated, and successfully, in climates so cold and humid as to prohibit the growth of wheat, and in climates so warm and droughty as to pre- vent the cultivation of the oat. Barley, therefore, is an important cereal ; for it is not only marked for the wide range of climates in wrhich it can be grown, but also for its adaptability to high regions, placed at an elevation con- siderably above that at which wheat can be grown. 2. Barley belongs to the class of monocotyledonous plants, the sub-class glumifera, order gramina, and the genus hordeum. The following is the generic description of the plant : " Inflorescence, spiked, spikelets are flowered three together, the two lateral often barren (as in the two-rowed barleys); glumes, two, equal, opposite, so small as to re- semble short awns or bristles ; palese, two, the lower one bearded, the upper with two heads; scales two, stigma feathery, seed surrounded by the palese." The number of species, and the varieties of each species, is by no means a settled point. Professor Wilson inclines to believe that Gasparin's classification of two species, the two-rowed, (hordeum distichon, figs. 2, 3, and 4,) and the six-rowed, (hordeum hexastichon, fig. 1,) is the one which is botani- cally correct. Professor Lindley maintains that all the so- called species or varieties which some authorities, as Kunth, reckon up to as many as fifteen, are but variations of the original type, and this, he says, is the "two.ro wed" or what is called the " common barley." Of this genus, the original type of all the barleys now grown, he says, " the spikelets always stand in threes, and the threes being placed back to back, it is evident that every ear of barley must consist of six rows of spikelets. If the middle spikelet of each set of three is alone perfect, the side spikelets being abortive, we have the common two-rowed barley (hordeum distichon) and its many varieties. If the CLASSIFICATION OF BARLEY. 187 two lateral of each set of threes are perfect, and the centre spikelets imperfect, as sometimes happens, we then have the four - rowed barley ; if, on the other hand, all the spikelets are perfect, we have the six-rowed barley, but the case of the four-rowed barley being merely accidental, they may be referred to the six-rowed form, and then we have only two principal kinds of barley, the two-rowed (hordeum distichon), and the six-rowed (hordeum hexastichon)" In Scotland, however, the four-rowed barley is so much grown and known under the name of "here" or "bigg," that it seems necessary to include this as a species under its bo- tanical name hordeum vulgare, although this kind is rarely grown in the southern districts of the kingdom. The fol- lowing is the generic description of the three species named above, beginning with hordeum vulgare : " Florets her- maphrodite ; fertile, middle grains 'on each side forming a distinct straight row, lateral ones forming a kind of double row towards the base, but uniting so as to form one row towards the extremity of the spike." The different parts of " bere " are proportioned as follows : the grain nearly 51 parts out of the hundred, the awns nearly 6 parts, the straw nearly 38, and the roots nearly 5^ parts. The varieties named by Mr. Lawson are eight in number, (1) common "bear," "here," or "bigg;" (2) Square barley ; (3) winter barley ; (4) African, Tangier, or Morocco barley ; (5) Bengal barley ; (6) black winter barley; (7) naked Siberian barley ; (8) Nepaul or Himmalaya barley. Some of these are not now cultivated. The following is Professor Wilson's classification : (1) black four-rowed ; (2) Victoria bere ; (3) winter white ; (4) Peruvian. Of these the Vic- toria is probably the finest. " The straw and ear are longer and stouter than the common bere ; the grain is much heavier, weighing up to 54 or 56 Ib. per bushel; and the produce is much larger, from 10 to 12 quarters per acre having been obtained to the acre." Peruvian is a naked barley, of which Professor Wilson says, the char- acteristic seems to be that they " are not so well suited for our climate as the ordinary barley," thriving " best whera 188 - CULTURE OF FARM CROPS. a short but hot summer enables them to carry on a perfect and rapid growth." 3. The following is the generic description of the hordeum hexastichon, or six-rowed barley ; (fig. 1,) " all the florets hermaphrodite and awned, seeds placed regularly in six row.3, has a much thicker spike than common or spring barley, but is also much shorter ; the number of grains, however, in the ear or spike is greater, in proportion of at least three to two. The ear is seldom more than two inches in length." The species is hardy and prolific, but yields the coarsest sample of all the varieties grown ; the grains are long, ill filled, and the awns adhere to them with much tenacity. It is not much grown in this coun- try, but when grown, it may either as spring or winter bar- ley, it being found to answer for either one or the other. There are no varieties of this species. The ripening is late, a fortnight or so beyond other kinds. The proportions of the parts of this species are as follows : — grain, 51 ; roots, 12; straw, 32; awns, 5 in the hundred. The third species yet to be noticed, hordeum disticJwn, the common two-rowed barley, figs. 2, 3, and 4, has " ears in general three or four inches long by one-third of an inch broad, containing 28 or 30 grains, which are not very close set on the raches ; awns extending about the length of the spike beyond its point." Mr. Lawson names of this species seven varieties, — (1) Chevalier, (2) Annot, (3) Dunlop, (4) Stains, (5) Golden or Italian, (6) Chancellor, (7) Eupton. Mr. Keary, in his prize essay on ' Barley Management,' of which further notice will be taken hereafter, says, that of all the varieties of barley, Chevalier decidedly ranks high- est for malting purposes. To the objection that it does not yield so much per acre as other varieties, he states that under proper cultivation, there are few sorts to be com- pared with it. 4. The following from Mr. Fyfe's paper in the "Journal of the Bath and West of England Society,'' on " Farm Seeds and Seeding," on the subject of barley seeds, will usefully conclude this part of our subject. Fig. 2. Fig. 1 190 CULTURE OF FARM CROPS. Fig. 4. Johnson's Providence Prolific. CLASSIFICATION OF BARLEY. 191 " The practical procedure in regard to barley, then, runs thus, — the Chevalier, the Thanet and the common barley ; the recommendation of the Chevalier consisting not only in its popularity with maltsters, but in the fact of its tall, stout straw not being liable, in the general experience, to lodge, and even when it does lodge, not. being subject to after shoots of germ, although one of our correspondents reports otherwise. The great fault of the common barley is its liability to over luxuriance, and to shank over at the knee when too richly manured. When grown on warm friable soils, or even when deeply deposited in a tilthy bed, it is best adapted for succeeding turnips and for being eaten down by sheep ; but for that matter, so also is wheat, which, of all crops, loves a hard-pressed surface. One of our ablest correspondents states, however, that he has of late years grown wheat after all his root crops and barley, which he seeds down after his wheat. By pursuing this system, he grows first-class barley, and ensures better and more healthy crops of seeds and roots." Mr. Keary is a strong advocate for a "constant and judi- cious change of seed," and says that " although it may sometimes be expensive to obtain it from a great distance," he believes that it " will generally repay the cost by an increase of produce and an improvement of quality ; " and he gives the following instances confirming his opinions on this point, which we need not say, are those of the best authorities on barley cultivation : — " On two adjoining farms in a barley-growing district, both much alike as to quality of soil, the occupier of No. I being in the habit of constantly changing his seed and sowing tolerably early, and the occupier of No. 2 systema- tically never changing his seed and sowing rather late. The quality of the barley grown upon No. 1 in the year referred to was remarkably good ; and upon No. 2 it was so very inferior as to be quite unsaleable for any but the most common purposes, and 2s. per bushel, or 16s. per quarter, was the difference in the price these barleys fetched, at several times during that season, on the same day and 192 CULTURE OF FARM CROPS. at the same market. The produce per acre, also, was, as nearly as could be ascertained, very much greater on farm No. 1." 5. So much for the question of the change of seed, upon which little further need be said than this, that if the trouble and slight expense involved by following the plan here recommended by Mr. Keary, and so emphatically endorsed by other authorities, be grudged by the farmer, it is all the more imperative upon him to see that the seed which he does use of his own or his immediate neighbour's growth be of thoroughly good quality, clear in colour, with the ends in no way blackened, full, and plump in shape. "We have already passed a stricture or two upon the ab- surdity of using bad wheat for seed purposes ; it is no less patent, nor, we regret to say it, less frequently done in the case of barley. Indeed, it is altogether surprising, when we think of the " natural fitness of things," to see how careless many farmers are on this point of " seed." Anything with some seems good enough for seeding ; nor need the poorness of some crops, which a walk through almost any district in the kingdom will too readily show, be at all wondered at, when we come to enquire into the nature and quality of the seed which has been used. It is worth while to remember, what is unfortunately too often for- gotten, that as the seed, so the crop, and that a vast deal of the cost and labour of the preparation of the land may be absolutely thrown away by the carelessness we may dis- play in the choice of the seed which we commit to its bosom. With reference to the change or choice of seed, Mr. Fife remarks — " As the foreign names of many of our barleys imply, the best change is considered to be from a distant and very different soil; and whether from an early to a late, or vice versa, this sort of change is of vital im- portance. But it should be observed, that the change of seed from an early to a late district is found to be the means of hastening the period of ripening and of affording the chance of a finer quality of produce ; whilst the change from a late to an early district will retard the time of ripen- THE TIME OF SOWING BARLEY. 193 ing, but afford due time for perfect ripening. The very best quality of seed that can be procured should in any case be used." 6. The time of or period for sowing the barley crop is an- other important part of its economy, and one to which the attention of the careful farmer is now more directed than ever. In many districts it is, as a rule, sown too late ; and in connection with any crop it may be laid down as an axiom, the later the sowing the poorer the yield. The celebrated Arthur Young was amongst the first to point out the value of early sowing of barley ; and the following is a statement of the results of some experiments of his to determine the point. Barley sown in February yielded 12^, in March 11J, April 8|, May 6J, in June 3£th. We have said the later the period of sowing the poorer the yield ; this may, however, be taken with this reservation or addition — the later the period after a cer- tain date ; only it is difficult to name what this date is. Locality, climate, the peculiar nature of the season, will all bear upon the decision of this point, and varying as they do, will of necessity introduce such disturbing elements into practice, that it will be difficult to lay down a rule which will be applicable to all districts ; nor, indeed, one which, if shown applicable to a certain district one season can be applicable in the same district at another season. In truth, in connection with this important point, as in fact with many other points of agricultural practice, little is left us but conjecture — by none of our agricultural societies has the determination of this question, by accu- rately comparative experiments, been taken up. Conjecture, however, is all in favour of early sowing — say, from the beginning of March to that of April, and all sowings after the latter date may in favourable districts be set down as risky. It would be well for the interests of agriculture if our Scientific Associations were to take up now and then the consideration of questions other than those which seem alone now to occupy their attention and engross their cares, and this to which we have now alluded might very 194 CULTURE OF FARM CROPS. usefully "be made one of them. Mr. Keary has some re- marks on the " risks" as well as the " advantages " of early sowing, in which he adverts to what we have already drawn such marked attention — namely, the difficulty, or rather the '* impossibility," as he puts it, of " iixing any period for sowing which will suit all circumstances and all seasons." If the weather is good and the land is dry and works well in February, early sowing will " unquestionably improve the quality of the barley ; " but Mr. Keary doubts as to the yield being increased. This, as will be noticed, is in direct opposition to the results of Young's experiments. Mr. Keary, however, distinctly states what all will agree with, " that it never can be judicious to meddle with the land in the spring till it is dry and works well." On strong cold land the sowing of barley should be earlier than when the land is light and sandy and the subsoil warm and dry. In the strong cold land there is no danger, says Mr. Keary, of a " too rapid growth in the first stages, and the land having sufficient staple to carry it out, the quality of the grain will be improved and the period of cutting will be accelerated. On the other hand, if sown before the land is in proper tilth and fit to receive the seed, a rough coarse sample will be produced." As to very late sowing, Mr. Keary states that its "invariable" result is an "inferior quality of corn." A great deal necessarily depends upon the weather in the choice of the period for sowing ; but if success is desiderated, it is essential that the land at the time of putting in the seed must be in a favourable con- dition. What that is is indicated by the saying that " in sowing barley the dust must rise above the harrows ;" and yet this, like many other apparently decisive sayings, must be taken with reservation, for although the land should be dry, it should only be so relatively, for a certain amount of moisture in the soil at the time of sowing seems to be a necessary condition in insuring a successful braird. If the weather during the preparation of the soil has been so favourable as to admit of a fine tilth being secured, then the best condition in which it can be for putting the seed SOILS SUITABLE FOR BARLEY. 195 in, is after a slight shower has moistened the soil. The plan of moistening or damping barley seed in very dry weather has been suggested as a good means of securing a braird. (7.) A slightly moist, a soft and friable soil, is necessary for the barley. To secure the two latter features, the whole of the details of the preparation of the land must therefore be carried carefully out, and they at the same time indicate the nature of what is called " barley " soil, a thing essen- tially different from a " wheat so.il," which latter is diffi- cult to bring into the fine friable tilth so necessary for the barley. As regards the soil, then, for the barley crop, Professor Wilson sums up the whole that need be said on the subject thus : " Agriculturally speaking, their range is from the lightest gravels up to the medium loams ; beyond a medium loam the proportion of clay renders the soil unfit for the cultivation of barley." The difference in the struc- ture of the roots of the wheat and the barley plants indi- cates the difference required in the soil, or rather its con- dition. The roots of the wheat have a remarkable ten- dency to push themselves deep into the soil as well as to ramify in all directions; those of the barley plants have the power given them of spreading laterally, and a de- velopment remarkable for its quickness. We see, then, the wheat plant distinguished by what we may call a ver- ticality of root-development and a slowness of growth, and the barley by a horizontality and a quickness of growth. The roots of the Avheat plant draw their assimilable food from the soil slowly, and from a great depth ; those of the barley have to draw it quickly, and from the surface, and much more in a given time than the wheat roots. This quick abstraction of the food from the soil by the barley plant is also aided by a peculiarity which distinguishes them — namely, the number of root fibres or " hair-like processes" by which the roots are supplied, and which Pro- fessor Lindley calls " the mouths of the root." A quick drawer and a greedy drawer of the manurial matters con- tained in the soil, and that soil confined by the habits of growth of the plant, the inference is readily drawn, that 196 CULTURE OF FARM CROPS. the crop which precedes the barley crop should be that which leaves the soil in the condition best fitted for these habits, and rich in manurial constituents — these conditions indicate, therefore, a root crop as that which should pre- cede the barley. The processes involved in the prepara- tion of the soil for the root crop are just those which bring about the condition best fitted to aid the growth of barley ; and the advantages of the rotation are perhaps rendered still more striking when the turnip crop is partly or wholly fed off by sheep. " The appropriateness of this course for barley rather than for wheat, besides the advantage arising from the season of the year at which the land is generally clear for the corn, rests mainly on the fact, that the ma- nure by folding, with the subsequent light working of the land, is more confined to the superficial layers of soil in which, comparatively, the roots of the barley play more freely." At the same time, however, it is to be noted, that a "disadvantage of growing barley after the folding of sheep on turnips is, that with high farming the land is apt to be thus left in too high a condition for the crop to suc- ceed well in the average of seasons ; whilst on the heavier lands there is frequently much injury done to the texture, rendering it difficult to get the fine tilth so essential to the favourable growth of barley." 8. The various points connected with the question, What is the best rotation for any given crop ? while they are most important, and while their right solution would exercise a most favourable influence upon the practice of agriculture, are unfortunately so difficult of decision, and involve so much that, if not often contra- dictory, is at least conflicting and confusing, that the whole subject of "rotation" is yet in a most unsatisfactory con- dition. " Rotations, or systems of cropping," as so sugges- tively pointed out by Professor Wilson, " must be more or less guess-work, founded, if you please, upon long practice and experience, but good only where exactly the same con- ditions can be secured." But however much discrepancy there may be between the statements and opinions of far- SOILS SUITABLE FOR BARLEY. 197 mers as to the beet rotation to be adopted in the case of any crop, and however much men may disagree as to the details, still all must, we think, unhesitatingly coincide with Mr. Lawes and with Dr. Gilbert when they urge the " ne- cessity of considering the various habits and conformation of the different crops of our rotations in relation to their sources of growth;" and agree with them in this also, " that the important bearing of such considerations in modifying the conclusions to which a more purely chemical view of the offices and province in a system of manuring of the various constituents would lead, is one of the first lessons which the progress of field experiment teaches." These celebrated agricultural authorities point out very clearly the conditions of growth of the barley, and which we here epitomise. The autumn crop of wheat depends greatly for its success upon the progress during' the early months of its growth on its underground development. Other things being equal, this development of root is greatly favoured by a liberal supply of nitrogen within the soil ; and that this being supplied, the range of feeding ground, so to term it, of the fibrous roots, was so extended, that the mineral constituents of a much larger area of soil than would have been otherwise the case were rendered avail- able, when needed, in the after stages of the plants. The case is, however, very different with the barley crop ; here winter-growth and a compressed soil, which tend to increase depth and area of root-distribution are not present or de- siderated; on the contrary, we have spring growth, the staple of soil shallow, light, and open. Under these cir- cumstances, and a limited period of growth, we find the " direct supply of some of the rarer but essential mineral constituents of our soils much more efficient with the bar- ley crop than with wheat." With the multiplication and thickly-distributed net-work of roots, which we have shown to be the characteristic feature of the underground develop- ment of the barley, " the greater must be the resources of the plant within its comparatively limited period and area of growth." Thus it is that the increased supply of cer- 198 CULTURE OF FARM CROPS. tain important constituents within a limited area, enables the plant to provide itself more freely and rapidly with others it may require. 9. Messrs. Lawes and Gilbert, as the result of an elaborate series of experiments upon the growth of barley, have shown that '' the produce of barley obtained in rotation (the usual four-course or Norfolk system — turnips, barley, clover, wheat), even when the turnips were both unmanured and carted off, was considerably greater than when the crop was grown annually in succession on the same land," so that, as they remark, it may fairly be concluded that a " characteristic effect of alternating the other crops with the barley " is to leave more available nitrogen from some source within reach of its roots than is the case when the barley is grown in successive crops on the same land, or when a number of turnip crops were likewise taken in suc- cession off the land previously; and the conclusion they arrive at is, that, like wheat, barley requires " a nitrogenous condition of soil," and that full crops cannot be obtained unless there be within the soil available supplies of nitrogen. The bearing of those remarks upon the question of rota- tion is important, and will at once be recognised by the intelligent reader. 1 0. Let us, then, now draw our attention to a review of the modes in use for the cultivation of barley. We have already referred to the preparation of the land. In a prac- tical paper on the " Management of Barley " by Mr. H. W. Keary, a prize essay published in the " Journal of the Royal Agricultural Society," there are some very excellent remarks on this point. And here the importance of attending to this may at once be recognised, from the fact, so carefully pointed out by Mr. Keary, that upon it depends most ma- terially the quality even perhaps more than the quantity of the crop. So that although, as a rule, what are called " barley soils " produce the finest yield both iir quality and quantity, still remarkable differences in these respects are noticeable, and this arising from the different modes in which the same kinds of barley are cultivated. Mr. Keary MODES OF CULTIVATING BARLEY. 199 gives some most excellent remarks upon the modes prac- tised in various districts. In several of the midland counties there are fine deep loams upon gravel, and also upon clay, which produce a " very bold heavy barley," but which, however, does not take the first place in the London mar- kets for malting purposes. On such districts, and with this soil — termed turnip and barley soil — the barley is usually taken after the turnips, the turnip crop being pre- viously fed off either wholly or partially by sheep. It is on such soils that the truth of the adage, " Sheep have golden feet," is so well exemplified. The land, firmly con- solidated by the treading of the sheep, and well manured by them, is broken up by the plough in the autumn or winter months, and allowed to remain exposed to the ame- liorating influences of the atmosphere till seed-time. The land — and this by the practicians of some districts is worthy of notice — is not again ploughed in spring, but simply scarified, or grubbed, and well harrowed. The seed is then deposited generally by the drill, but sometimes it is broad- casted. A good deal has been said upon the comparative advantages of these two modes of sowing, but while there are benefits to be derived from the dispersing of the seed over the ground — for the more this is done the better — still the fact that the depth is unequal operates most pre- judicially against the broadcasting system, for the growth is most unequal, some of the grains having a start long before others, so that the quality of the sample at harvest- ing is most unequal also, and the trouble involved in cut- ting very considerable. JSTow, by using the drill, we can secure uniformity in the depth at which we deposit the seed, and, what is of immense importance in a crop where uniformity in the quality of the sample is so important, we can also secure uniformity of growth and of ripening. In the midland districts which we are now considering, the sowing season varies, according to circumstances, from the middle of March to the end of April, the seeds sown be- longing to the varieties known as Chevalier, Nottingham, Long Ear, and the old Common barley. Of these the Che- 200 CULTURE OF FARM CROPS. valier is gradually growing in repute, more being grown now than formerly, even although the quantity per acre is not so satisfactory as other varieties; but it "is highly esteemed for malting purposes, and therefore commands the highest price. Barley in these districts is sometimes sown after fallow, this being where the soil is rather a " strong clay." In autumn the land is left in a rough and cloddy state from the plough ; and the seed is sown upon this as early after February as possible, and then dragged or scuffled in without further preparation. Simple as this plan appears, Mr. Keary states the crops produced by it to be very good, and inclines to the belief that possibly for such soils it is the best that can be adopted. In some dis- tricts of the southern counties the turnip-land is ploughed up as soon as it is dry, well worked twice with the drag- harrow or with the scarifier, and then the seed is drilled at the rate of three bushels to the acre. The common sort of barley is generally used, the Chevalier not being there a favourite in consequence of the low quantity of its yield. In Herefordshire, which is celebrated for the fineness of its barley crops, the best crops are grown upon the light soils which have a chalk subsoil. Generally these lands are ploughed only once, the seed being sown in March or April. On the stronger lands of this country, fine malting samples c^uld not be obtained from the old Common bar- ley sown ; now, however, this difficulty is obviated by the use of the Chevalier variety. 11. Although the barley crop is one which delights in a genial warmth of soil and of climate, nevertheless we find its extension very marked in what one would suppose to be the apparently (for barley) ungenial districts of the York- shire and Lincolnshire wolds, with their somewhat northern districts; but good farming has overcome the difficulties arising from this circumstance, and the barley grown in these districts equals, if it does not excel, that of other and more favoured places. The white turnip is generally grown in these northern districts, the crop being fed off either par- tially or wholly by sheep; if swedes are grown, they are MODES OF CULTIVATING BARLEY. 201 not taken up and stored, but left in the ground till wanted in spring. The reason why white turnips are grown in place of the elsewhere more esteemed swedes, is, that the farmers of the wolds believe that a better crop of barley is obtained after them than after the swedes. Now this opinion is directly opposed to the experience of the Nor- folk farmers, so celebrated for the fineness of their barley crops. As the point is one of a decidedly practical and important character, it will be worth while to devote a little space to the consideration of its details. The swede crop is almost universally allowed to be richer in nutritive qualities than the white or common turnip, and it may therefore with safety be predicted that the land will be more fertilized from the application of the manure of sheep fed upon swedes than when they are fed upon white tur- nips. Further, the longer a crop is allowed to remain upon the ground the more does it exhaust the land. Now, in Norfolk, the swedes, when grown, are taken up and stored; while in the wolds of Lincolnshire or of Yorkshire the white turnips are allowed to remain in the ground till wanted in spring. Now, asks Mr. Keary, may not this circumstance be the reason why such a difference of opinion exists amongst the farmers of two districts alike celebrated for their good farming] and on the point between them Mr. Keary has no hesitation in giving in his adherence to the opinion in favouF of the swedes as the best crop to precede the barley ; and he believes that, by the extension of growth of this valuable root, not only would more sheep be maintained, but that by the increased fertility which would by its means be given to the land by the manure obtained from the sheep fed upon it, it would benefit the clover crop, which follows the barley, and ultimately the wheat, which follows the clover. In the wold districts of Lincolnshire and Yorkshire the land is bro- ken up by the plough after the turnips are fed off by the sheep; it is then, on the approach of seed-time, dragged and harrowed; and the seed is generally sown broadcast, at the rate of 10 to 12 pecks per acre — the seed- 202 CULTURE OF FARM CROPS. time varying from the first week in March to the last week in April. 12. We shall now briefly glance at the practice of the celebrated barley-growing districts of Norfolk. As already stated, the swede is the favourite crop for sheep-feeding purposes in this county, and is that crop which precedes the barley. But in addition to the use of this nutritious root by the " go-ahead " farmers of the county of the cele- brated " Coke," large quantities of oil-cake, crushed barley, and pease, are given to the sheep. To this system of feed- ing, by which such a valuable manure is obtained, may be attributed the rapid fertilization of some of the worst lands of the county ; and Mr Keary believes it to be by far the best and cheapest mode of bringing a poor farm into a high state of cultivation, for the cake, &c., " passing through the animal, an increase of matter is added to the increase of corn, and the cost of artificial manure is thus doubly paid for." But while the barley crop is by this system undoubtedly raised in quantity, it is thought that by it the quality is deteriorated; although the pecuniary result may not be affected, the decrease in the quality being more than balanced by the increase in the quantity. In the districts which we have already described, the practice is, as we have shown, to plough the land early and well in the autumn. Now, in the Norfolk district, it is a very general practice to plough twice, experience having, it seems, in- variably shown that more barley is produced when the land is ploughed twice than when it is ploughed only once. In ploughing once the manure of the sheep is not so in- timately mixed with the soil, the greater portion remain- ing at the bottom of the furrow ; while by ploughing twice the manure is equally and intimately mixed with the soil. The last ploughing is done immediately before sowing, so that a kinder, lighter, and more genial seed-bed is found to be the result than when the sowing takes place on the " dead surface of the land ploughed up many weeks pre- viously." But it is worth while to note that, although the experience of the Norfolk farmers is such as we have NORFOLK SYSTEM OF CULTIVATING BARLEY. 203 now described it to be, it has nevertheless been found that in all soils, except those of the very lightest and the most sandy character, the use of the plough for originally — or for the first — breaking-up of the land for the barley crop, is not so beneficial as the use of the grubber or the scari- fier; the furrows turned over by the plough being gene-- rally of such a close and impervious character as to be little influenced by the beneficial effect of the frost and atmospheric influences during the winter months. In some cases, therefore, a strong scarifier, with the teetli closely set, is dragged over the land in autumn by four horses, and it is left in the consequent rough and uneven condition all the winter. The plough is then used to prepare the land for sowing in the spring, this being done immediately before the seed-time, the seed being then put in. Another plan is sometimes, folio wed; in this the iron mould-board of the plough is removed, and a piece of rough wood substituted, the object of this being to pre- vent the furrow being turned completely over, leaving it in an unfinished or roughly broken condition. By the im- plement thus prepared the land is broken up in autumn, and left rough till spring. As soon as the season is suffi- ciently far advanced, and the land dry, it is well harrowed ; and immediately before the . seed is thought right to be put in, the second ploughing is performed, and the seed put in. In the large light-land fields of the western dis- tricts of Norfolk it is usual to plough the whole field, and drill across the ridges or furrows. This plan of drilling across the furrows produces a more uniformly deep seed- bed; for it is obvious that where the converse of this holds, and the drill follows the furrows of the plough, the seed will not be deposited equally deep, the surface being uneven, and the drill-coulters running into the furrows will render the work done uneven. After the drilling is per- formed, the land is well harrowed, and sometimes the roller is used in place of the harrow; the grass-seed machine then follows, after that the light harrow, and the sowing process is then completed. Where the soil is stronger, the 204 CULTURE OF FARM CROPS. drill follows the plough, and this especially in wet weather, the object aimed at being the thorough completion of each day's work before night sets in. In these soils the barley is allowed to stand through the ground, and be pretty strong in the blade before the roller is applied, This is light, and its office is to break up the clods, and give a little fresh soil and firmness to the roots of the growing plants. On light tender lands the seed is sown broadcast, and turned in with a light one-horse plough ; this practice was common formerly throughout the county. In the strong soils of the county which are apt to work unkindly in the spring, the following plan of preparing the land by the two-furrow or ridging system is adopted. A rather shallow furrow is taken at first, and the return is made with a deeper one, leaving a small " balk," and turning it over so as to make a complete ridge. The ridges thus formed are allowed to remain exposed to the atmosphere for some weeks, and as soon as the weather allows in early spring the plough is used to reverse these ridges, and open up and expose their interior to the atmosphere. These ridges are in their turn allowed to remain for some weeks till seed-time approaches, and then a skeleton-plough is used to split them up; the land is then well harrowed and levelled as much as possible. The drill then follows and the operation is completed. If all these operations are effected properly in dry weather — for which see an after note — a most admirable seed-bed is secured. The plan, however, is open to objections, of which the following are stated. It is difficult to get the land completely level, and hence, particularly in a dry season, the crop conies up unequal in growth, being much stronger in the alternate rows, the furrows thus showing themselves in the growing crop. This irregularity of growth is of course more ob- servable in the early stages than in the later, but it is obvious that its tendency is to maintain itself throughout the season of growth, so that an irregularity of ripening of the crop and in the quality of the sample must be the consequence. WEATHER FOR SOWING BARLEY. 205 In the Norfolk district, which we are now considering, the sowing season extends from the middle of March to the end of April, but the first half of April is considered' in average seasons the most favourable time. Where land works well, early sowing of barley is good ; and in Nor- folk, in the strong soils, it is sown early in March. " Chevalier " barley is rapidly becoming a favourite. " Brewers' Delight " grows stiff in the straw, yields a good sample, equal for malting purposes to " Chevalier," and is therefore fast coming into repute. The old " Common Barley " is now but little used. " Long-eared Nottingham " is used by some, " American " by others, and by others again a variety obtained from Leghorn. We must draw special attention to the remarks of Mr. Keary on the importance of attending to the weather in which, as well as to the details of the mode by which, the work is performed. A great point undoubtedly is to obtain a slightly damp seed-bed; but while this is worth aiming at, it is impossible to find language strong enough to condemn the absurd practice of working the land when it is thoroughly wet — " when the water stands in puddles on the surface." This, however, is not done in order to get the kind of seed-bed we have alluded to above, but specially to accelerate the spring work. The ploughing is then done, it is true, but it is not sufficiently considered that numerous harro wings, rollings, and perhaps clod- crushings, must be gone through before barley can be sown amongst clods, which are the sure result of working in wet weather. Soil forced thus into tillage rarely yields the kind and genial seed-bed required for barley. Some sea- sons are, however, so continuously wet that it is difficult, if not altogether impossible, to get the land in proper con- dition for working. Mr. Keary mentions a plan for work- ing barley soil in wet weather which he describes as being specially successful. A piece of cord was tied round the mouldboard of the plough, this preventing the smooth shiny surface given to the furrows by the plough in its ordinary condition, and entirely removing the necessity to 206 CULTURE OF FARM CROPS. use the roller. The mode already described of breaking up the land in autumn by a grubber or scarifier, and ploughing the land immediately before sowing, appears to Mr. Keary and other authorities to be preferable from every point of view to that where only one ploughing is done, and then putting in the seed. 13. As to Mr. Frere's opinion that the barley takes less out of the land than the wheat crop, seeing that it runs coun- ter to the one frequently held, it will be well to note what is said in support of it. The land selected for trial by Mr. Frere was the very weakest portion of his heath land, " black sand on chalk rubble." On this, which is too light to carry any other " lay " than ryegrass, with an admixture of trefoil and Dutch clover for sheep food, " the worst part of the field has been left, at wheat-sowing time, manured and ploughed at leisure during winter, and sown with barley on the whole furrow in the spring, part of it having been folded, the rest having received straw manure, — a ton or two less per acre than would have been applied to wheat." Now those who rely upon the respective an- alyses of the ashes of the wheat and of the barley crop will, from their similarity, believe that they are equally exhausting crops. But Mr. Frere, in advancing the con- trary opinion, points out that our best chemists believe that the cereals are parting with nitrogen to a considerable amount, and that during the " whole course of their growth." As a result of this, the waste of this valuable manurial agent will depend upon the duration of the growth of the plant ; so that more nitrogen will be parted with by the winter wheat, the growth of which extends over so much longer a period than the barley sown in spring. Of course, the much - disputed question arises, Granting that this parting of nitrogen by the cereals is correct, does it follow that the soil is consequently weak- ened 1 Those who believe in the large amount of ammonia derived from the air will of course hold as favourable to their views this same " nitrogenous exhalation " of the cereals, rather than the reverse. But to these Mr. Frere SOWING OF BARLEY. 207 puts the following — " Until we have better evidence that the nitrogen, as united with oxygen • in the air, becomes largely available for plants, how can they account for the supply of ammonia and nitric acid on which they rely ? " But apart from all " scientific speculations," Mr. Frere be- lieves that "our growth of barley" may safely be increased on suitable soils, " and this in view of the facts, that while the prospects of wheat are precarious, those of the barley crop are steady, and that by improved skill in brewing, and by the facilities now offered for transporting beer to great distances, the. competition offered by the increase in consumption of foreign wines is counterbalanced." The following shows the combined results of the crops of the four following years : — Value per Acre Value per Acre Years. of Barley (on of Wheat, whole furrow.) 1859, . . .£890 £700 1860, . . . 840 9 10 0 1861 (nearly), . . 11 0 0 900 1862 (over), . 10 0 0 10 12 0 £37 13 0 £36 2 0 Average, . . £983 £906 We now come to the consideration of the points con- nected with the quantity of the seed to be sown, and the modes in use for sowing it. As in connection with the wheat, so with the barley crop, great difference of opinion exists as to the quantity of seed per acre to be used ; some advocating thick, some thin sowing, while as to the modes of sowing it, the same diversity of opinion also exists; so that some advocate the broadcast, some the drill, and some the dibbling systems. Much of what we have said on all these points having special reference to the wheat crop (see volumes on the Culture of Wheat) applies equally well to the barley crop. Although broadcasting may be said to be the rule, still an immense advantage arising from the adoption of the " drill- ing system " is the facilities afforded by it to clean the crop during the early stages of its growth. We are aware that 208 CULTURE OF FARM CROPS. this hoeing and cleaning is not by any means general; yet if the reader will draw to recollection what has been given in a former part of the present chapter as to the habits and characteristics of the barley plant, he will at once perceive that the growing crop will be immensely benefited by being cleared from weeds, and the soil consequently well stirred, so as to admit abundance of light and air, and allow the atmospheric influences thus to operate in their usual bene- ficial way. As to " dibbling," from what we have heard, and from the result of numerous experiments of our own, we are inclined to think it is even more specially valu- able for the barley than it is for the wheat crop — so much so, that if the difficulties attendant upon carrying it out on the large scale are considered such as to be prohibitive of the system, we would at all events most unhesitatingly recommend its adoption in all cases where a special supply of seed is to be raised from some favourite variety, or where experiments are being carried out. The whole question of thick and thin sowing is invested with so many points of immensely practical importance that we shall be pardoned if, in addition to what we have already said upon it in a previous paper, we here draw attention to some very sug- gestive remarks 011 it by M. Bodih, of the Agricultural School at Rennes, who is a strong advocate of thin-sowing. Referring to the well-known dicta, " On rich land sow thin ; you will always have sufficient seed;" and, "On poor soil cover the field with seed — you cannot put in too much," M.'Bodin says that it will be worth while to inquire from whence the notions involved in these sayings have sprung, and how it is that it has come to be believed that putting a large number of plants into land which does not contain nutritive principles, and few into soil which contains much nutriment, opposed as seems written on their face, to com- mon sense. Under the impression that sowing thickly would choke the weeds, M. Bodin has adopted it in the case of certain crops, but the results obtained taught him, he says, a lesson. By sowing thickly on poor soil, each grain produces only one stem, and that stem only one ear ; THICK AND THIN SOWING OF BARLEY. 209 by still farther increasing the quantity of seed, the produce is still poorer. By the invariable law of plant growth, all the plants will give some grain; but the question arises, "Will the stems form themselves, if, by thick sowing to excess, they grow up thicker and poorer 1 Doubtless, the more the stems are numerous, the poorer in formation will they be, for we put fifty in a space adapted only, perhaps, to grow ten, and yet we expect a good result from such a mode ; certainly an expectation as likely to be realized, as he who, putting three times more stock upon poor pasture than he would upon good pasture, fancies he will obtain a better result. The more we encroach upon the available resources of the soil, by putting the plants living upon it to an extreme in number, the more do we reduce the quantity of the produce : if we sow fifty where we should only have ten, it is obvious enough that the food fit for the full development of ten only must be divided among fifty, to the manifest disadvantage of every individual one of the fifty. . But not only is the supply of food to each plant lessened in proportion to the excess of plants partak- ing of it, or withdrawing it from the soil, but another and a very serious disadvantage arises — namely, the roots get crowded and entangled together, and the " tillering," which is so essential to the healthy development of each plant, cannot be secured. It is difficult to say what is the mini- mum of earth or root space required by each plant, but, judging from the extraordinary extent to which this de- velopment takes place where the plant is allowed a large space of soil to grow in, we have no hesitation in saying that, as a rule, no plant receives, in practice, its proper allowance of feeding and growing ground. We remember very well the result of one out of many experiments we instituted on the modes of sowing thickly and thinly, having reference to the extent of underground (root) de- velopment and upper growth (stems and ears), how struck we were by the extraordinary mass of rootlets, and the fine display of stems and ears of a cereal plant dibbled (one of many sown at 12 -inch intervals), and another of the same 210 CULTURE OF FARM CROPS. variety sown broadcast in the usual fashion. The broad- casted-planted bore a few long lanky stems and small ears; the dibbled, which, in comparison, might be called a forest of stems like pillars, round, long, and strong, bearing full and large ears ; the first with a small knot of rootlets, the dibbled plant with a huge bunch. The two displayed a fine illustration of "the thin and ill-favoured," and the "full, well-favoured " ears of the corn seen in Pharaoh's dream. But to return to M. Bodin's remarks on this most interest- ing subject. While approving of thin sowing, he does not pretend to state the exact quantities which it is necessary to sow to produce a good crop; nor does he approve of " calculations taking for their base the quantity of grains sown ; " on the contrary, the yield per acre seems to him the most certain. For " in fact," he remarks, " if I sow some grains singly upon a large surface, the plants will develop themselves in an extraordinary manner, and I shall have an enormous produce compared to the quantity of grain sown, but very little compared with the extent of ground. By this means we shall gather thirty or forty to one, being, however, a small return per hectare. It must, therefore, be left for the cultivator to judge the quantity of seed required, taking care not to diminish it beyond what is necessary for the stems to fill the soil." 14. In examining the practice of farming in many dis- tricts, one is frequently struck with this, that many modes are adopted which seem to have for their aim to overcome an evil which owes its existence to a bad system, so that if the system was remodelled, preventing the recurrence of the evil, the detail in the mode would not be necessitated, seeing that it was alone adopted to overcome the evil. Many examples of this will recur to our readers, and one may be met with in the argument used in favour of thick sowing for some of our cereal crops (as, for instance, that of the barley, which, as is well known to many of our readers, should, according to almost general belief, " lie thick upon the ground") — namely, that it keeps down the weeds, which develop most rapidly when the seed is sown THE OAT CROP. 211 thin or in rows. But as M. Bodin well remarks, " it would be better to destroy the weeds by second hoeing or cleaning, than to run the risk of spoiling your crop, which there is great danger of, if it is left to fight its way amongst the weeds." Weeds and crops must be always antagonistic ; good farming has for its only aim the growth of the crops, and its most untiring and energetic efforts all conspire to prevent the growth of the weeds. M. Bodin concludes his paper by giving a saying, which, although soritewhat exaggerated in tone, carries with it, nevertheless, a vast deal of truth — " The worst weed for the corn is corn." On this point of thick and thin sowing, Mr. Keary, the author of the Prize Essay on Barley, of which we have already given a resumd, states that he is inclined to adopt a middle course between the extremes of thick and of thin sowing. " From eight to ten pecks per acre in kind and genial soils will generally suffice ; but on unkind land, in imperfect tilth, it may occasionally be necessary to sow a larger quantity." CHAPTER SECOND. THE OAT CROP. 15. THE next of the cereal crops demanding our attention is oats — that crop, the produce of which was defined by the able but at times somewhat surly English Moralist, as " food for men in Scotland and for horses in England ;" but the lurking prejudice of which definition was well met by the smart rejoinder, " Yes, true enough, but where will you meet with such men and such horses." Notwithstanding this deprecating estimate of the value of the oat, the crop is not only in Scotland, but in many parts of England, an important one. In Scotland, indeed, in some districts, it is not second in importance to any of the cereal crops ; if behind wheat, in the estimation of farmers there, certainly before barley. What we have had to say in connection 212 CULTURE OF FARM CROPS. with the history of wheat and barley, we have again to say in connection with oats. All we know, indeed, of the time and place and manner of their introduction into the cate- gory of animal food is, that we know nothing. All is conjecture, and conjecture, moreover of the vaguest kind ; less frequent mention is made of the crop in those documents which take cognizance of the other cereals ; and in Holy Writ no mention is made of it at all. In the records of Ttonian History the same absence of direct information re- specting it is noticeable ; although a curious indirect yet sufficiently suggestive testimony respecting it is met with in the statement or story that the Emperor Caligula, in the very arrogance of wealth, fed his horses with gilded oats, from which, if we like, we may draw a moral of some suggestiveness to us all. Eepeating the stereotyped infor- mation we possess on the history of the oat, — which being met with everywhere where the subject is discussed, is excuse enough for its being mentioned here — writers state that its origin may be traced to Persia or Mesopotamia ; and, in corroboration of this, the fact is stated that Colonel Chesney found growing wild on the banks of the Euphrates, a variety of oats, which, although very unlike our oats, Dr. Lindley says may yet be their progenitor. Having given this, we give all the information we know as to the history of this crop, and proceed therefore to the more in- teresting, because more practical details connected with its cultivation. 1 6. Oats belong to the class (in the natural system) of Di- cotyledonous plants, the order Graminse, and the genus Avena. The number of species is considerable, some nam- ing them up to fifty ; but of these, by far the greater num- ber are of no agricultural value as cereals, being, in fact, but grasses or weeds ; this reduces the food oats, so to call them, to the following families, under which all the varieties of oats cultivated in this country are classified. These are (1) Avena sativa, or the common oat ; (2) A. Orientalis, the Tartarian oat; (3) A. brevis, the short oat ; (4) A. nuda, the naked oat ; and (5) A. striosa, the bristle-pointed oat. The VARIETIES OF OATS. ' 213 general appearance of the oat is so well known as to re- quire no specially lengthened description ; popularly the distinction between it and the wheat and barley is that, while in these the grains are congregated round a central stalk more or less closely, the grains of the oat are sup- ported on tender stalks, which spread out branch-fashion from a central stem. More scientifically stated, oats are characterized by " their lax panicles, their two lax mem- braneous glumes, and the "smaller number of their florets, each of which has one of its husks or palece armed with a twisted beard or awn." But there is a distinction yet to be noted, distinguishing the varieties of the two first-named species, while the varieties of the Avena sativa or common oat, fig. 5, are distinguished by the grains or glumes being borne upon stalks spreading out from a central branch-tree fashion on all sides ; the varieties of the species of Avena orientalis or Tartarian oat, fig. 6, are at once known from their glumes or grains being placed on or proceeding from the main stalk on one side only, presenting the appearance, indeed, very much of the feather on one side of a common quill pen. To these two species, the common and the Tartarian oat, belong all the varieties cultivated in this country. What these varieties are we now name briefly here. To the first-named of the species, Avena sativa or common oat, belong (1) the Potato, (2) the Sandy, fig. 5, (3) Sheriff, (4) the Hopetoun, (5) the Angus, (6) the Blainslie, (7) the Late or Common White oat, (8) the Berlie, (9) the Poland, (10) the Canadian oat, fig. 7. Of these, (1) the Potato oat is the favourite and the most ^argely cultivated. Mr. Lawson states that this variety was first discovered growing amongst some potatoes in a field in Cumberland in the year 1788. Another writer, in the Farmer's Maga- zine in 1803, states that the variety was first imported from South America, a few grains only having been sent enclosed in a larger package containing potatoes, the name was given to them. The seed of (he potato oat is white, plump, and short ; it weighs heavy, in sample from 40 to 4-6 Ibs. per bushel, and if well cultivated, will yield from 214 CULTURE OF FARM CROPS. Fig. 5. Sandy Oats. VARIETIES OF OATS. 215 Fiff. 6. Tartarian Oats. 216 CULTURE OF FARM CROPS. Fig. 7. Canadian Oats. VARIETIES OF OATS. 217 6 to 1 0 quarters to the acre. The yield of meal is in gen- eral high, as much as 245 Ibs. having been obtained from one quarter ; the average may, however, be put down at 210 Ibs. per quarter. The straw of the potato oat is of a pale yellow colour, and carries, when well grown, a large " bushy ear." The seeds being very apt in this variety to be shed, the crop should be cut before it is dead ripe, — a good indication of the proper degree of ripeness having been attained, being in an equal mixture of the green and yellow colour in the straw. The potato oat is, per- haps, one of the most remunerative of all the varieties, if grown upon a suitable soil, on which point we shall hereafter have more to say; meantime noticing the second of the varieties of which we have above given a list, namely, the Sandy oat, fig. 5. Mr. Lawson states that this variety was discovered in 1824-5 011 the farm of Miltown, in Aberdeenshire, by a herd boy named " Sandy Tampson," who first saw it growing upon a recently formed bank of soil ; his master, Mr. Price, noticing its value, cultivated it from year to year. The sandy oat is better suited for late districts than the potato, and although it does not yield so much in meal, it is, nevertheless, esteemed by the millers. The grain is smaller than the potato oat ; the straw is stiff, tall, and not easily lodged ; and the grains are not so apt to be shed ; when the crop may be cut therefore at a later period of its ripening, the whole straw should indeed have a pale yellow colour before being cut. (3) Sheriff oat. This is comparatively a new oat ; in some cases, with a favourite soil and under good cultivation, the yield is very high. It is earlier in point of ripening than the potato oat ; the straw is of moderate length ; the grain is smaller and lighter than the potato oat. (4) Hopetoun oat. When first introduced this variety had a high character ; it had a larger straw and a stouter than the potato oat ; and was considered remarkably free from a liability to lodge. Now, however, according to an authority, its degeneracy is such, especially in the latter respect, that " no variety so easily bends over and becomes straw-broken as the Hopetoun. 218 CULTURE OF FARM CROPS. The variety has a grain, however, of good quality, large, with a thick husk, the colour of which is darker than the potato oat, and can be readily distinguished from it " by a small reddish mark in the centre of the front of the grain." The variety is largely cultivated in the north of Scotland. The period of ripening is much the same as in Potato and Sandy oats. (5) The Angus oat. This belongs to what are classed as (7) the late or common oat. The characteristics of the common white oat are large grain, thick husks, and late maturity. The Angus resembles the Potato oat in quality, it is not so liable to shed when ripe. (6) The Blainslie oat is greatly cultivated in the south-east of Scot- land ; it has a good well- filled grain of good quality ; it is early. One peculiarity of the common oats is the excellent fodder provided by the straw. The grain is well liked by the millers, as the- meal yielded by them is of superior quality. (8) The Berlie oat is of two kinds, the English and the Scotch : of which, says Professor Wilson, the English " delights in good rich soils," the Scotch being " better adapted for light than for heavy." The grain of the Berlie oat is good, yields a good quality of meal, the straw is long, and the seed rarely sheds. (9) Poland oat, much grown in England, but inferior to the Potato oats ; there are two varieties, the black and the white. Intermediate between the varieties of the two species, the Avena sativa or common oat, and the Avena orientalis or Tartarian oat, we may class the " Dun oat," which may be, as it has been, looked upon as a hybrid between the two species above- named. The Dun oat is divided into two varieties, the common dun and the winter dun. The common dun is grown largely in some parts of Scotland, but always as a spring crop ; it yields largely, the grain is of good quality, the meal obtained from it is good. The straw is long, but is not apt to lodge ; the period of ripening is rather late. The winter dun is more cultivated in England and the Con- tinent than in Scotland ; in the former countries it is sown as a winter crop ; being often eaten down by sheep in spring, and then allowed to grow for seed. The straw is •shorter than that of the common ^un. VARIETIES OF OATS. 219 1 6. Of the Avena orientalis the two varieties are the black Tartarian and the white Tartarian. As already stated, all the glumes are carried on one side only of the stalk. The seed of the black Tartarian oat is very long, and frequently, under bad culture, provided with a long pointed beard or awn. Particularly well suited for peaty soils, it often, when well cultivated in such, yields from 80 to 90 bushels per acre. The straw is short; the grain, if good, short, and plump. The black Tartarian is a great favourite in many districts in England, not only from the large produce it yields, but because the grain is particularly valuable for the feeding of horses. The meal produced from it is par- ticularly good, the only fault being that, from the black colour of the husk, small black specks give a dirty look to it. The white Tartarian is also very productive ; the grain is larger than the black Tartarian, of a dull white. The straw is long and stout. Like the black, the white Tartarian oat is highly esteemed for horse-feeding purposes. Mr. Haxton, the author of the prize essay " On the Cultivation of Oats" in the Journal of the Eoyal Agricultural Society of England, states that he "dibbled 23 varieties of oats in small lots after lea in a piece of good black land, and the results were very decidedly in favour of those which we have marked 1, 2, 3, 4, 7. The best crops he obtained were from the 'Sandy' and ' Hopetoun' among the early varieties, and from the 'Late Angus' among the common oats. The Sandy and Late Angus gave the greatest bulk, and the straw of both stood remarkably well, although nearly 6 feet long. The latter was 10 days later of being reaped than the former, and even then it was scarcely ripe. Had it been allowed to ripen fully, the difference would have been from 15 to 18 days later than the Sandy. It may be mentioned here that, although these experimental crops were sown with little more than 3 pecks to the acre, the crop was fully better than that sown broadcast along- side with 4 bushels to the acre." 1 7. With reference to the varieties of oats used in Scotland, and the soils to which they are adapted, Mr. Lawson^ the 220 CULTURE OF FARM CROPS. eminent agricultural botanist, has some valuable remarks. He mentions that although there are about sixty varieties of oats met with, still considerable confusion exists with reference to them, many possessing such a close approxima- tion to each other in external appearance that it is difficult to separate them into classes ; of these sixty varieties, thirty therefore may be taken as applicable to Scotland ; and of these thirty, some dozen only are in general cultivation. These dozen may be named here : - — Potato, Hopetoun, Sandy, Early Angus, Late Angus, Grey Angus, Blainslie, Berlie, Dun, Friesland, Black Tartarian, Barbachlaw. Mr. Lawson has classed these oats according to the soils and situations, thus : — First Class, adapted to the best soils and sheltered situa- tion— 1. Potato Oats, Hopetoun, Flemish, Early Angus, Cupar Grange. Second Class, to intermediate soils and situations — 2. Sandy, Dyock, Berlie, Ked Maobiehill, Blainslie, Grey An- gus, Late Angus, Poland, Friesland, Lancashire Witches, Tarn Einlay, Drummond, Pun, Sheriff, Cumberland Early, Cleland, Siberian, Georgian, Blue Major, Church's. Class Third, high altitudes and exposed situations — 3. Kildrummie, Strathallan, Black Tartarian, Old Black, Bar- bachlaw, Black Muckle, Bristle Pointed. 1 8. Mr. Lawson points out what he considers to be the com- bination of qualities necessary to be attained in oats, which qualities, he truly observes, must be ascertained or obtained by " much care, attention, and frequently repeated trials." The qualities are — (1) quantity and quality of grain ; (2) quality and bulk of the straw ; (3) early ripening ; (4) power of resistance to wind and water, &c. ; (5) adaptation to the exposure and altitude of different soils ; (6) freedom from disease. Knowing these qualities, the next point is to ascer- tain the variety best calculated to give out these. Should this variety not be in existence, it must be obtained, says Mr. Lawson, by either the improvement of an old, or, by cross impregnation, the generation of a new variety. 1 9. Of the principal points connected with the soil and cli- SOILS AND CLIMATE ADAPTED FOR THE OAT. 221 mate adapted for the oat crop, the writer above named (Mr. Haxton)has given a most suggestive, if not the most exhaust- ive resume. We shall therefore do well if we present to our readers a condensation of this. Scotland is selected, and selected with precise judgment, as the " type of an oat- growing country;"' with a cool climate, the mean maximum in the hottest month of the year, and in the warmest dis- tricts not exceeding, the soil is peculiarly adapted for the crop. The climatic or weather influences which affect the oat crop are different from those which affect the barley and the wheat; so much is this the case, that we have no difficulty in knowing — if from no other sources of informa- tion than that of the market prices — that where the first price is got for the barley or the wheat of any district, that the oats of that district will not be good ; and the converse of this holds equally good. For instance, the wheat and barley grown under proper conditions in districts south of the Humber are as superior to those grown to the north of the Tweed, as the oats grown to the north of the Tweed are as superior to those grown to the south of the Humber. Nor is this marked difference traceable to any difference very marked in character between the geological formations of the soils ; doubtless these differences do exist, but in no way so marked as to account for the differences we have named as existing between the quality of the crops. The opinion is thus likely to be a true one, that the difference arises more from a difference in climatic than in geological causes ; this influence or opinion is corroborated by the fact that as we proceed northwards and westwards in England, we come to districts adapted for oat growing. This view receives further corroboration in taking into account the " extraordinary results that have been produced by certain climatic aberrations which have -occurred within the pe- riod of the present century. Thus, in the very dry sum- mer of 1826, the oat — especially in the drier districts — was an extremely light one ; while, on the other hand, the wheat crop was an extremely good one, bearing a marked resemblance to the superior quality of south of England 222 CULTURE OF FARM CROPS. grown wheats in moderately warm weather. In other countries, both in Europe and America, although lying within the same parallels of latitude as Scotland and the north of England, the oat crop is a failure, or at least gives an inferior yield, and this, apparently, owing to the high range of summer temperature prevailing. The conclusion, then, arrived at, is, that the northern parts of this kingdom, and nearly the whole of Ireland, derive their oat-growing capabilities in the first place from their insular position, and, in the second, from the mountainous character of the land — a combination ensuring a " large amount of aqueous vapour in the atmosphere," and its deposition in the ground in the form of refreshing rains, mists, and dews. But while Scot- land retains as yet her pre-eminence as an oat-producing country, just as she has, by improved modes of cultivation, enabled her farmers to raise now better crops of wheat and of barley than were produced half a century ago, so may we expect that, by a like introduction of improved practices into the south of England, succeed in raising good crops of oats — that grain which will always possess a high value in the farm, if not as food for men, as food for horses. But although it is apparently true that good crops of oats de- pend more upon a proper condition of climate than upon the qualities of the soil — for good farming produces good crops in all soils — it is not by this meant to be assumed that the quality or nature of the soil is a matter of little or no importance — not so, for assuredly one soil is better adapted to produce a good quality than another ; and there are also certain districts in which oats of one kind succeed well where oats of another kind will not succeed at all. We proceed, therefore, to take up the subject of the soils best adapted for the growth of the oat. 2 OrFor the earlier varieties of the Avena sativa class of oats, such as the Sandy, the Potato, the Hopetoun, &c., the best soils are those derived from the alluvial deposits of the " trap " and " new red sandstone " formation which form the lower parts of valleys and the more level districts in which these two classes of rocks abound. So that, as a SOIL ADAPTED TO THE OAT. 223 rule generally applicable, it may be stated that " wherever a soil has been formed by the alluvium of rocks or strata not characterized by the presence of too great an amount of aluminous or clayey matter, there we have a soil which, if drained and in proper condition, will produce excellent crops of the finer varieties of oats." Such is the soil of the county of East Lothian, and, to a certain extent, also that of the southern part of the county of Fife, the soil of this being composed of trap debris and red and yellow sandstone deposits. All soils derived from trap rock, greenstone, ba- salt, and porphyry, as is the soil of the northern part of the county of Fife, are to a greater or less degree fitted for growing good crops of oats, the lower parts of the districts where these rocks abound affording a rich alluvium capable of growing crops " with little trouble or expense ; " and even in the higher and more thinly covered parts, good crops may be obtained if sheep-folded and kept two years under grass. 21. Good crops of oats are produced on soils derived from the mountain limestones, but they demand more rich ma- nuring than the freer trap and lower soils. 22. On the clay wheat soils of the celebrated Carses of Gowrie and of Stirling, the cultivation of oats is not other- wise generally there precarious, much depending upon the character of the seeding time. When the soil has been properly mellowed by the winter's frosts, if the seed-time is dry, and the periods of growth of the crop not too wet, the Carse lands produce very heavy crops; but still, unless all the conditions are favourable, the crop is, as we have stated above, a precarious one, and does not assume the important position in the, rotation which it does in other districts. In clay soils oats are found to succeed best after a crop of red clover — the stronger the clover is, the better the oats. On the outer edges of the clay barriers being reached, we come to a lighter class of soils, which produce good crops of oats, so that the crop may in such situations be made to form part of the rotation. 23. The soils of England similar in character to those 224 CULTURE OF FARM CROPS. of the Carses of Gowrie and Stirling above described, are those met with in the Wealds of Kent, Surrey, and of Sussex, the Gault of Cambridge and Huntingdon, and all the varieties of clay — the dread of many a farmer — known as the London or Plastic clays, unfitted for the production of barley, it is very desirable to have oats grown upon them ; but this is difficult to be done in some of them; if at- tempted, it is at the best a precarious and uncertain crop, although, in some of the better class, oats could be grown if properly drained. Even the most tenacious of these bricky clays could be rendered more fitted for the oat crop by properly draining, liming, and carefully working them. As already stated, red clover should precede the crop, the land being ploughed early in winter or late in autumn, so that the atmospheric influences may be allowed to operate as long as possible in order to mellow and pulverize the soil. 24. What are sometimes called '''vegetable manure soils," that is, deep alluvial soils rich in vegetable matter, are " peculiarly adapted to the production of oats," that is, of course, when passed under a proper regime of culture. Indeed, where the climate is peculiarly cold or wet, oats is the only cereal crop that can be successfully cultivated on such soils. Soils of this character possess the property of capillary attraction in a high degree, so that when tho- roughly drained, or when the season is warm, the moisture they retain is quite sufficient to supply the crop during the period of dry weather; on the other hand, they can stand long-continued rains better than clay soils, which get under such circumstances what is called " soured," and if dry weather succeeds, cracked and baked. The Fens of Eng- land have long been famous for the productive crops of oats, and are cited by Mr. Haxton as an evidence that a " certain degree of depth and dampness in the soil," even in districts not climatically suited to the crop, compensates for their higher temperature and for the lack of atmospheric moisture. There can be no doubt that this point of cli- matic influence upon the productiveness of the oat crop is SOIL ADAPTED TO THE OAT CROP. 225 of very great importance, and should not be overlooked in treating of the economy of the plant. Having thus glanced at the peculiarities of the best, and at the moderately good soils for the oat crop, let us do the same office for those not so adapted. 25. As the soil from the alluvial deposit of the trap and new red sandstones may be looked upon as the best and most fertile for the oat crop, so may the soil, composed of " loose calcareous matter," be looked upon as the most sterile. Of this class are the upper chalks of England, incliosavi sands and gravels. Mr. Haxton, in treating of this class of soils, draws attention to the fact that it has been frequently remarked that in the case of light soils, which have been long under cultivation,, a second applica- tion of lime, if not positively injurious, is at all events not beneficial to the oat crop ; indeed, that an " overdose of caustic lime, or of purely calcareous chalk, is frequently productive of the worst results." He names instances where light gravelly soils were rendered incapable of grow- ing oats for a long time through having been top-dressed with a rich calcareous shell marl found in beds underlying peat. On all light soils composed principally of gravel, sand, loose brown earth, or decomposed peat long under cultivation, lime should be sparingly used, as an overdose is always fatal to the success of the oat crop. The same effects of an overdose of lime are not observable, it is right to state, in deep alluvial soils, whether these be made up of clay, loam, or of black mould. Loose, mossy, or gravelly soils, which have been long under cultivation, are, accord- ing to the experience of this authority, always the worse of liming ; and the point is all the more worthy of obser- vation, as on the first of these, namely, mossy or peaty soils, oats, as we have before stated, is the only cereal crop which can be cultivated. Of course, in the primary treatment of peaty or mossy soils liming is essential, in order to act- upon the inert vegetable matter, and neutralize or bring into good action the acids with which it abounds; but as soon as the soil is fairly formed by liming and by proper 226 CULTURE OF FARM CROPS. culture, a second liming will be found more injurious than beneficial; bone manuring will therefore be better than the application of lime or of shell marl. Clay marl, rendering it, as it does the light soil, more cohesive and more absorb- ent and retentive of moisture, will be beneficial in such cases. Of all the profitless and annoying soils to take in hand for the cultivation of the oat crop, that class known generally as moor-band is the worst ; in these soils, indeed, consisting of mossy land overlying a subsoil of mixed clay, sand, and oxide of iron, oats as a rule refuse to grow. The moor-band, forming a hard impenetrable crust below the upper surface, completely prevents all capillary action from below, so that in dry weather there is no moisture ascend- ing to the roots of the oat crop above ; and the consequence is, that at a certain stage — generally as the ear or shot blade is being formed — the plant begins to droop, to turn yellow, and finally and completely to blast all hopes of a coming crop. The result is all the more depressing, inasmuch as generally the crop at its first start has all the appearance of a peculiarly healthy and promising one. Even when drained and fairly well cultivated, moor-band soils never yield a successful crop of oats. The following is a list of the soils adapted for oats arranged into groups, commencing with the highest or most favourable soils. First Glass — (1) Eich, friable, reddish-coloured loams, either alluvial in their origin or derived from the new or old red sandstones, or basalt, or from greenstone. ('2) Eich, black loams, at the base of " trap " hills. (3) Drained and clayed fen lands. Second Class. — (1) Limed and furrow-drained clay. (2) Medium trap and whinstone soils. (3) Light loamy land. (4) Moss or peaty 'land reclaimed. The soils of both these classes are, with the exception of the last (4) of the second class, well adapted for wheat as well as oat crops when they are situated in a dry and a warm climate. The second soil of the second class — light loamy land — as also the third, require to be folded by sheep or consolidated by roller to improve their consistency. On all soft soils, as reclaimed peat, soft loam, or black earth, the oat crop SOIL ADAPTED TO THE OAT CROP. 227 assumes of necessity a prominent position, as barley is prac- tically excluded from them through the tendency it has to produce straw rather than grain. And although wheat can be, and is, grown in black earth or soft loam soils, still this is only the case where the climate is dry and warm, 'and where the intervals between its appearance on the same soil are longer than is usual under ordinary rotations. Oats, therefore, in such soils becomes the grain crop to which all the aims of the farmer should be turned. The third class of soils is made up of (1) thin gravel soil left by the infiltration of water ; (2) poor whinstone soil situated on the higher parts of greenstone trap hills; (3) loose sandy soil; (4) loose calcareous soil; and (5) cold, poor clay soil. It is only by putting this class of soils under the highest farming, or by keeping them under grass for a long period, that they can be made oat-producing. Even where the climate is cool and moist, it is a difficult matter from such soils to raise good crops of oats ; it is therefore almost useless to try to do so where they are situated in dry and warm districts. The easiest and the most econo- mical way to bring such soils, where the climate is suitable, into oat cultivation, is to pasture them two or three years in every rotation, and where turnips can be grown, to bone manure them, and eat them off the land by sheep. On the subject of oat cropping of such lands, Mr. Bennett states that upon stony, poor, sterile clay land, no crop will pay better than the oat when taken after the summer fal- low. In Bedfordshire, on land of this class, the following is the plan of cropping which, Mr. Bennett adds, may be carried on with advantage ad infinitum — One-eighth of the fallows to be a dead or summer fallow, the other one-eighth to be sown with winter tares, eaten off by sheep, and fal- lowed. In the succeeding year, the eighth which was bare or dead fallow is to be cropped with oats and seeded down; the other eighth which bore tares, to be cropped with barley, and not seeded. The crop next taken off this to be beans, the other being seeded. At Michaelmas, the other two-eighths, or one-fourth, to be wheat. As seeds 228 CULTURE OF FAKM CROPS. (grass) never flourish after tares, the eighth tnat was under summer fallow should only be seeded. 26. As regards the kind of soil best adapted for the differ- ent varieties of oats we have already named, the following " notes " may be useful : — For potato oats the best soil is black land, or reddish-coloured loam of a consistent and firm texture, but not clayey. Sharp trap whinstone soils, and the better class of granite soils, are also well adapted for the potato oats. As on clay land the roots of the plants of the potato oats are apt to become sedge-rooted when there is much rain in spring or early summer, this class of soil is not fitted for this variety. Sandy oats grow better in clay land than the potato ; they are most valuable on soft moss soil. The Hopetoun oat grows well on light soils; but not on high and exposed parts. For peaty or marshy soils, the black tartarian oat is well adapted, that is where they are well cultivated, and clayed or gravelled ; it is also a good variety for high lying, late districts ; but is not suitable for dry trap soils. The Dun oat grows best on clayey or cold soils; becoming rapidly deteriorated in light dry soils. 27. The place of oats in the rotation of a farm is usually- after grass which has either been cut for hay or pastured ; although a modification will depend upon local and other circumstances. In the five or six course of husbandry, oats come, as above stated, after the seeds or grass. The crop may, however, succeed beans or turnips ; in some districts in England, it is taken after the wheat ; throughout Scot- land, the rule is pretty universal that the oat should follow the grass crop. The modes of managing the land after grass, are fully detailed in the paper to which we have alluded, and we shall therefore give a resume of what is there stated in connection with it. If the grass has been down only for one year, and then depastured by sheep, it is looked upon as valuable for the oat crop as if it had been grazed for two years by cattle, and this on account of the equal distribution of the manure over the surface, given by the sheep. PREPARATION OF THE SOIL. 229 28. While excellent crops of oats can be got off first- class soils after rye-grass or clover, cut for summer soiling or for hay, — on second class soils, to have them of the neces- sary fertility, it is necessary to pasture them with sheep for one year, or graze them with cattle for two, before breaking up the grass land for the oats. Where the grass is, however, cut for hay the first year, the after-grass should be depastured, and sheep folded on it the following winter, these being fed with turnips, cakes and grain. If this is done, giving one acre of turnips to three acres of the lea, the manuring the land will receive in this process will be as good as that obtained by depasturing the grass with sheep for one, or with cattle for two years. When the soil is inferior, the grass should be kept down, as we have already stated, at least two years ; but all the better crops of oats and succeeding crops will be obtained, if three years be the period. 29. Although climate has a remarkable influence on the oat crop, irrespective of the condition of the soil, still the preparation of the land for the crop is a matter of great importance. Generally it may be stated that, resembling in its habits of growth the wheat more than the barley plant, a good, deep, well-stirred soil is necessary for it ; the roots having more of the descending vertical develop- ment of the wheat, than the lateral development of the barley plant. Further, although loving a moist climate and soil, a thoroughly wet one is prejudicial in a high degree to the oat ; well drained, in addition to deeply stirred soil, is therefore essential, if indeed the one can be obtained without the other. In Scotland, the ploughing of lea for the oat crop is looked upon as one of the nicest operations which the ploughman is called upon to perform, and is carried out with the most'scrupulous care, the pride of the ploughman being bound up in its beautiful execu- tion. The lea ploughing is not usually begun till near the New Year ; but it is in February — the frosts then being not so severe — that the principal labour is performed in this department. The older and tougher lea land 230 CULTURE OF FARM CROPS. should be ploughed up the first, as it requires to be longer acted upon by the frost and atmospheric influences of the winter ; clover being the freest, may be ploughed up last. Mr. Haxton recommends the press roller to be used in plough- ing lea for oats, as by it the grassy part of the furrow slice is completely pressed down and buried ; a seed-bed being at the same time formed by the tapered or conical periphery of the wheel. The operation of press- wheel rolling is also thought to be beneficial in preventing the ravages of the wire worm, which does great injury to the oat crop. It is necessary, however, to state, that the action of the press-wheel roller is not so beneficial, if indeed it should be used at all, on damp or clayey soils ; it certainly gives the best results on light soils. In ploughing lea land, it is absolutely essential to note par- ticularly the condition of the land as regards its moisture ; lea should never be ploughed in so wet a condition as to leave a glazed surface on the furrow slice. This may be done, as it is often done, early in the season when succeed- ing frosts are likely to follow which will mellow down the glazed furrow slices ; but if done late, the chances are that the glazed furrow slice becomes hardened, and will not yield kindly to the pulverizing influences of the harrow. There is no point more frequently overlooked by careless farmers than this, of the condition in which the land is when being ploughed. In preparing land for oats after a root or fallow crop, it is usual, at all events it is deemed advisable, to plough land as soon as the roots are taken off the land, giving a second ploughing in the spring, should that be necessary ; this second ploughing may, however, be avoided by ploughing deep enough at the first, so that a sufficient depth of mellowed soil may be obtained in spring time. 30. On the mechanical condition of the soil necessary for the oat crop, Professor Tanner has given some excellent remarks in a paper in the " Journal of the Eoyal Agricul- tural Society," of which the following is a brief resume : Oat plants possess greater vital or natural energy than PREPARATION OF THE SOIL. 231 barley, resembling, indeed, in this respect, the wheat plants. This influences the preparation which it , is desirable to give to the soil upon which the crop is to be grown. Oats are usually taken either after roots, or upon a fresh broken clover lea or turf. When taken after roots, the land is usually ploughed once, and allowed to remain sufficiently long exposed to the atmospheric influences to be mellowed, before the seed is sown. When the crop is taken after clover lea or fresh broken-up turf, the ploughing should be so much the earlier performed, as the turf is hard and tough, so that as long time as possible will be given to the atmospheric influences to mellow and reduce the clods. If the turf is old, the ploughing should, therefore, be done before December at the latest ; a two or three year old clover lea may be left unploughed till a later date than this. It is admitted, however, that whether in the case of old turf, or two or three year old clover lea, an early ploughing is better than a late, for the longer the period under which the clods are exposed to the atmosphere, the more mellow, and therefore the better fitted for the crop the soil is. 31. In order to get the grass of turf land well turned in, it is advisable to use the skin coulter ; and in addition to the use of this appliance to the plough, the land press roller or wheel maybe used with advantage; the object being not only to bury the grass completely, but to give a solid furrow. Left thus in autumn, the land exposed to the atmosphere and frosts in the winter, gets into the mellow friable condition best suited to the crop ; a seed- bed, in fact, possessing all the necessary characteristics — " well charged with vegetable matter, firm beneath, yet easy of penetration for the rooting of the plant, with a surface light and free in its character for the germination of the seed. This firmness of land upon the root must be distinguished from the hardness with which wheat will contend after it has once made a fair growth." Professor Tanner makes pointed reference to the difference between the liking — so to speak — of wheat and the oat plants for 232 CULTURE OF FARM CROPS. firmness in the soil; and notes, that he has known wheat land so " fearfully trodden during the winter (by no means an unusual circumstance in hunting districts, when a large number are in at the death) that all vestige of the wheat plant has been destroyed ; and yet, at the following harvest the wheat crop on such portions has been very superior." This condition of soil the oat could not bear up against,, for although it requires a firm, it cannot do with a hard soil. No soil suits the oat better than a ploughed-up turf; so that conversely, the oat is the best crop to take off a strong turf. Thus, in the North of England, where the turf of a clover lea even often becomes too rank for the wheat, the oat comes in excellently as a substitute ; cases, indeed, are not often met with there, in which either wheat or barley can displace the oat crop in newly ploughed up old and rich turf. The oat crop is remarkable for penetrating and breaking up turf ; indeed, there is no corn crop so valuable for this — the turf presenting precisely that con- dition of soil required for the habits of the plant; and where the seed requires a light covering, the soil is exposed to the action of frost, and lightly tilled. To get the con- dition of soil necessary, the land should be ploughed " moderately moist," but it should be thoroughly dry when broken down for the sowing of the seed ; these points must be attended to, for if the land was worked down at seed time in that moist condition which favours the solidity of the furrow when the land is being ploughed up, the surface soil would be too close and adhesive to enable the seed to germinate properly. 32. If oats are sown upon turf, the seed should be sown earlier than if they follow roots or a bare fallow. To early sowing, this objection may be made, that exposing the early plants to frost, the blades may become bluish as if they were injured; but to this maybe answered, that even if this does result, the plants rapidly recover. Some have the notion that oat plants do not stand the frost well; this, however, is a mistake ; a very remarkable experiment was made many years ago in sowing oats at Christmas. The SOWING OF THE SEED. 233 plants not only stood the frosts which followed remarkably well, but the produce was very much larger than that of a field sown at the usual period. We ourselves have had oats which brairded in the autumn before the frosts had set in. and which stood its attacks when it set in fiercely remarkably well. Early sowing is now rapidly on the increase; and one reason, indeed, for the almost general use of broadcasting in place of drilling, is the rapidity with which the sowing is gone through, so that early sowing is obtained. Moreover, the land may be in fair enough con- dition for harrowing after broadcasting, yet not dry and mellow enough for drilling. Where time will permit, especially in the case of foul grass land, the drill should be used, as the use of this machine will enable the weeds to be destroyed by the after use of the horse-hoe, at least to such an extent as not to injure the crop, weeds being very noxious to it. 33. The seed being got in either by broadcasting or drill- ing, the harrowing should be well done, so as to cover the seed completely. Some use the roller to smooth off and slightly compress the land after the harrowing ; but as a general rule, it will be better to leave the surface rough after the harrow. The roughness thus given to the surface has many advantages attendant upon it ; the inequalities pro- tect the plants, affording, so to speak, little sheltered valleys between them, in which the early plants can grow when attacked by cold frosty winds ; further, that by the time the oats are ready for the roller, the clods will be well mellowed, and will be easily reduced by the action of the roller to a fine tilth, which will thus aid the progress of the plants by adding fresh soil to them. Upon blowing sands, this roughness of the soil is essential, as it is often the only means left for protecting the crop. Professor Tanner states that he has known the greater portion of an oat crop fairly blown off the land, through the surface having been smoothed off by the roller after harrowing in the seed. In such light soils, deep sowing — two inches — is quite necessary. Q 234 CULTURE OF FARM CROPS. 34. We now come to the choice of seed, and much of what we have said on this point in connection with the wheat and the barley crop will refer to the oat crop ; certainly not less pointedly, so far as regards this, that the quality of the seed be the best which can be got. We are no be- liever in the notion that poor seed grain gives good har- vest grain ; the very contrary we believe in. Further, the seed should be free from injury ; although, to be sure, this recommendation is of necessity involved in that already given ; for an injured grain cannot possibly be said to be of good, certainly not of the best, quality. Lastly, let the seed be true to its variety, for if you wish a certain variety for a certain purpose, or as being adapted for a certain soil, if you do not obtain this variety, true disappointment will result. We have drawn attention in a previous paper to the mixture of different kinds of seeds for wheat. However doubtful this practice may be in connection with the wheat crop, as doubtful by some authorities it is deemed to be, there seems little doubt of this, that a mixture of different varieties of oats is productive of considerable advantage. The following 011 the mixture of oat seeds is from the pen of the late and lamented Mr. Finnie of Swanston. " The practice of mix- ing two or more varieties of seed has become of late years very common in Scotland. The object for doing so is to obtain a heavier and more prolific crop, by taking advan- tage of the particular habit of growth of different varieties, so that the excellencies of the one may compensate for the deficiencies of the other. Thus it is common to sow a mixture of Hopetoun and Sandy oats, because the former is weak-strawed, stands thin on the ground, but very pro- lific ; while the latter is strong-strawed, grows thickly, but is less productive ; consequently a mixture of this kind generally yields a better crop than when each variety is sown separately. Of course it is necessary, in such cases, to select such varieties of oats for mixing as possess about the same degree of earliness, in order that the whole may come to maturity at the same time." The following results THE CHOICE OF SEED. 235 of trials on the same extent of land, made by Mr. Finnie, show the benefit obtained by a mixture. The following varieties used alone gave the results as stated, Potato oat 74 bushels, Hopetoun 65, Early Angus 77, Kildrummy 77, Dun 76, Blainslie 70, Gray Angus 63, Sandy (changed seed) 61, Sandy (home growth) 56. Whereas, the following results, Hopetoun (5 parts), Kildrummy (1), produce 85, Hopetoun and Sandy 80 bushels, Hopetoun and Early Angus 76, Potato and Early Angus 66, and Potato and Sandy 66 bushels. From these results Mr. Finnie drew the following conclusions. " First, it appears that Potato oats sown alone produced 8 bushels more than when sown with either Early Angus or Sandy ; secondly, that Hope- toun oats produced 20 bushels less when sown alone than when mixed with Kildrummy, 15 bushels more than when sown with Sandy, and 1 1 bushels more when mixed with Early Angus. If there was no difference of soil or treat- ment in the above comparison, it appears that the average increase of produce from simply sowing a mixture of oats amounts, in the cases selected, to 13 bushels, from a space of ground which took 6 bushels to sow it." These ex- periments show enough to induce others, probably on a more extended scale, to be made. While the practical man should never forget that such experiments are not absolutely correct as indicative of similar results under different cir- cumstances of soil, locality, and climate, all of which ex- ercise a most important and modifying influence, neverthe- less they are valuable as showing relatively the influence of certain modes of treatment. At the same time, it does not always follow that experiments made in one place, indicate what the results, even relatively, may be of exactly similar experiments made in another and a different place. Thus it may happen, as, indeed, in practice it often does happen, that the result of precisely similar experiments in different places may be precisely contradictory, the indications af- forded by them in one being totally opposed to those af- forded by them in another place. All these, and other considerations more or less important which might be named 236 CULTURE OF FARM CROPS. here, very forcibly bring again to our mind the point on which we have already insisted very strongly, — namely, the necessity that exists for our leading Agricultural Societies to come forward to institute a set of experiments which will set at rest, so far as they can be set at rest, the various questions now more or less disputed, and which influence, to a greater or less degree, the future of agricul- ture. We say, so far as such questions can be set at rest, the probability being that, in some, if not in many cases, we shall find that distinct and decided results applicable to all diversities of practice will never be obtained. But, as has been well remarked in scientific discussions, the an- swer No ! is just as valuable to us as the answer Yes ! There are therefore some departments of culture in which we are at present asking the question, Will this direction lead to practically useful results ? and which at present we must continue asking, seeing no one comes forward to say yes or no ; and it is clear that if progress in that direction can lead to no good, it is exceedingly useful for us to know that, inasmuch as we shall have at least the negative ad- vantage of knowing that all attempts to go in that direction will be but lost time. It so happens that there are in the cultural departments of agriculture many question, to which it is advisable that the answer Yes ! or the answer No ! should be given with all due speed. Isolated efforts to answer them must, of necessity, in a science with principles so unfixed and so liable to modification from ever-chang- ing circumstances as agriculture is, be unsatisfactory and vague to a greater or less degree. Why should these in- quiries, involving, as they necessarily do, the expenditure of much time and labour, be left to be pushed forward by private individuals 1 In view, indeed, of the persistent ef- forts made by our leading Societies in one or two direc- tions— oftener in one than in two unfortunately — we are very apt to ask what is the object of our Societies' exist- ence, or is it, indeed, an object that is one only ? How is it that so much attention is paid to our Stock, while ab- solutely none is given to the raising of the food which sup- SOWING OF THE SEED. 237 ports them. All the more urgently need the question be asked now at a time like the present, when the question is so often asked, " how are we to find food for our stock ? " often asked, indeed, not often satisfactorily answered. The subject then of action, on the part of our Societies, to take up the settlement of points connected with crop cultivation, is of great importance, second, indeed, we venture to main- tain, to none ; and the advocacy of which is in no-wise out of place in a series of papers, the one object of which is to gather up, from a wide variety of sources, all or nearly all that can be said on the subject. NOT is it the most con- vincing proof, if proof indeed is needed, of the amazing apathy of our leading Agricultural Societies on some of the most important departments of cultural economy, that in these papers we have little information to give of much value derived from the direct and immediate action of these Societies. True, it may be said that these Societies give — liberally it cannot be said they give — prizes for Essays on these very points. This, we take it, does not convey a correct notion of how the matter stands. These Essays are often, nay we say, almost always, very good ; but if based upon practical experience, that experience being that of in- dividuals, must necessarily be limited ; and if experiments are detailed, these also must be limited ; and we have al- ready insisted upon this, that the points about which so much uncertainty exists, can only be decided, if, indeed, they are at all capable of decision, by an extended series of experiments under different circumstances of soil, climate, and locality. Can this extended series ever be undertaken 1 will it ever be undertaken by individual enterprise ? There is but one answer, and one only, to this question. What that is needs not to be here at least explicitly stated. 35. There are still some points connected with the seed and sowing of oats to which we must refer here. As regards the quantity of seed to be employed, we find the same diversity of opinion existing which we find to exist amongst practical men on the wheat and barley crop ; some insist- ing upon thick, some upon thin sowing. It is worthy of 238 CULTURE OF FARM CROPS. note here, however, that the opinion of the most advanced authorities is the same as in relation to the wheat and barley crop, namely, that thick sowing is not so good as thin sowing. In Scotland, from 3j to 6 bushels per acre is a usual quantity ; in England, from 2 to 5. As a rule, thick sowing is carried out in Scotland on the ground that it is required, from the habit of the plant not to tiller out so well as the wheat or the barley crop. Mr. Haxton looks upon this thick sowing system as a decided error; and states that " the moistness of the climate has greatly favoured the practice, and counteracted its bad effects, by keeping these thickly sown crops in a healthy growing state ; but in a drier climate, the same error would occa- sion much more mischief, inasmuch as the thicker a crop is sown, the more does it ultimately suffer from long-con- tinued drought. Three bushels of early and small-seeded oats are quite sufficient to sow an imperial acre with, and 4 bushels of the coarser-grained oats." Mr. Bowie has in- stituted some experiments which tend to show the advan- tage of thin sowing. These experiments were carried out in a soil " rather poor than in good condition." The re- sults are therefore all the more suggestive, inasmuch as thick seeding is generally considered applicable to such soils ; thin seeding being considered only applicable to rich soils. The following is a tabular statement of results : — Quality of. Seed per acre. Yield per acre. Weight per bushel. Weight of Straw per acre.

On this, as on other points, it is not possible to lay down a rule applicable to all districts and localities, which must ever be decided by the peculiar circumstances at- tendant upon each kind of practice ; at the same time it SOWING OF THE SEED. 239 is worthy of note that the growing opinion is that in all cereals, oats, as well as barley or wheat, thin sowing is better than thick sowing j what the minimum and what the maximum will have to be decided according to circum- stances. The time for putting the seed in is a point of practice as much disputed nearly as to the quantity of seed to be put in. Like the latter the former point must be greatly dependent upon the locality and circumstances of soil. Just as the growing opinion is in favour of thin sow- ing, so is it in favour of early sowing. At the same time it is to be observed that the land must be in good condi- tion, that is, it must be sufficiently dry to work to a nice tilth. This circumstance will generally decide the ques- tion as to the period of sowing ; for whenever the land is in " good heart," as the expressive phrase goes, that is the time to sow, — indeed it appears that it cannot be too early in the year. As an eminently practical authority remarks on this very point, ."The time for sowing is to be fixed whenever the land will work, whether it be in January, February, or the early part of March." The same authority says, " never lose an opportunity of sowing when the land is sufficiently dry to work after the commencement of the new year." Another authority says, " the oat seed time in Scotland extends from the 10th of March to the 10th of April, according to circumstances. In South England, oats should be sown early in February, and even sooner, if the variety to be cultivated belong to the later sorts. By early sowing, the young plants are up and covering the ground before the hot season arrives, and the natural moisture is thus economized and preserved from eva- poration." 37. The sowing of the oat crop next demands our atten- tion. Generally the broadcast system is adopted, although the use of the drill is gradually extending from the south to the north. In Scotland, the oats are sown broadcast on the winter furrow, the seed being covered in by two, three, and sometimes four harrows coupled together; the number of harrows used, however, depends upon the quality of the 240 CULTURE OF FARM CROPS. soil — the lighter the soil the greater the number. The first stroke of the harrows is given in the direction of the furrows, the harrows following the sower, who can put in in level ground seed for 25 acres per day; in hilly, 20. The second stroke of the harrows is either across the ridges or obliquely to them. The amount of harrowing depends, however, very much indeed upon the nature of the soil. 38. Of the diseases of the barley and oat crop, little has to be said here ; those afflicting them and the wheat crop in common, having been fully treated of in a previous part of this volume. Of these diseases, the barley is peculiarly liable to the attacks of the fungoid disease called "smut" or uredo segetum. To the attacks of the other diseases of this class named in this volume on Wheat, barley seems little liable. Of insects, the barley is liable to the attacks of the wire worm, " elater obscurus." The oat crop is com- paratively little liable to the fungoid diseases which attack wheat ; the chief scourge being the wireworm and the grub. DIVISION SECOND. LEGUMINOUS CROPS. BEANS AND PEASE. CHAPTER FIRST. BEANS. 39. Of the crops which are grown primarily for their seed or grain, and secondarily for their straw, having dis- cussed those important ones yielding bread stuffs — the wheat, the barley, and the oats — we are now prepared to take up that class of this department of farm crops known by the name of leguminous crops, and of which beans and pease are the most important ; the name is derived from the word lego, which signifies something gathered by the hand. Of the two crops named above — the most important of the family — we shall take up beans first. The bean be- OEIGIN OF BEANS. 241 longs to the class of Dicotyledonous plants, that is, plants which have two seed lobes, or cotyledons, to the order Leguminosse, the family Faba Vulgaris, and the species generally cultivated in the fields is Faba Yulgaris Arvensis, that grown in the gardens being called Faba Vulgaris Hor- tensis, while a third species, being capable of cultivation in either field or garden, is called Faba Vulgaris Arvensis vel Hortensis. Not much is known as regards the history of the crop, more, however, relatively, than of other crops per- haps, and at all events more that is interesting and sugges- tive. We find mention made of them in Scripture, and the writings of Eoman authors abound in much that is very suggestive respecting them. The crop appears to have had its origin in Persia, from whence it was taken to Egypt, and from thence it spread to Greece and Spain. Egypt for long, however, was the country in which it was mainly culti- vated, the rich alluvial soil spreading out on either side of the noble Nile being particularly suited to its habits of growth. The Romans, as will have been gathered from what we have said above, deemed it an important crop, and paid great attention to its culture; through them it reached this country at a very early period in its history, where it be- came, and has since continued to be, an important crop. We have said that Eoman writers are found to make fre- quent and singular allusion to beans, and the supernatural qualities they were supposed to possess. Our readers will remember the mysterious precept of Pythagoras, " Abstain from beans," and the not less mysterious, at all events the very curious commentaries upon it, which have been made by learned writers of the middle arid of our own times. The Eomans seemed, however, to have derived their no- tions respecting the supernatural powers of the bean, like many other things, from that land of mystery, Egypt, and to have modified them considerably ; for while they cer- tainly did attribute very remarkable influences to the bean, and considered it unsafe to have much to do with them as an article of food, the Egyptian priests wdlit much farther, and maintained that it was a crime even to look at them. 242 CULTURE OF FARM CROPS. Very curious, truly, were the notions current about beans amongst the Romans; they were considered as decidedly opposed to that evenness and tranquillity of mind which, with the ancients, constituted the summum bonum; they were liable, if partaken, to render women barren; they were believed by some to be the residence of the souls of the departed, and, like the scroll of Jeremiah, they were written within and without with lamentation and woe, for their very leaves were supposed to be marked with the words of wretchedness and death. But notwithstanding all this, beans were largely cultivated by the Eomans, and in their writings we can to this day gather much that is really practically useful in modern culture of the crop. Considerable importance, therefore, we find was attached by them to the crop, evidence of which is found in the fact, that it gave a name to one of the most distinguished families of the most distinguished period of Roman history ; for as we find a family deriving its name, Pisanii, from the pea, so we find another deriving its name from the bean, the Fabii. 40. "We have already named the two or three species into which the genus has been, by modern authorities, divided ; of these there are many varieties. Formerly the vetch was the representative of the bean tribe, and the bean was classed under it as the vicia faba ; but the marked distinc- tion between the seeds — those of the vetch being round, while those of the bean are oval and compressed — caused later authorities to class the bean faba vulgaris as a distinct genus. Botanically described, the bean " has the flowers axillary, nearly sessile stalks, with several flowers very short ; legumes ascending, twined, coriaceous ; leaflets ellip- tical, acute, entire; tendril abortive; stipule half arrow shaped; toothed at the base, annual, flowering in June and July; stem, three to five feet high; leaflets smooth, larger acute at each end, and alternate; flowers from six to ten and more on a short racemose stalk ; white, with a broad black velvet-like spot on each wing ; calyx whitish, with ovate taper teeth ; legume large, thick, oblong, pulpy with- VARIETIES OF BEAKS. 243 in while unripe, containing four or five seeds; root, tap- shaped, descending with lateral fibres." 41. Of the varieties of beans cultivated in this country, the folio wing are the principal : — (1) The "Horse or Scotch ;" (2) the "Tick;" (3) the "Heligoland;" (4) the "Winter Bean." The long-podded beans, and the Windsor, are more garden than field beans, while the variety known as the Mazagan may be classed, as it has been classed, as an intermediate variety between the short and the long pods, and is adapted for both field and garden. Of the varieties named above (1), the Horse Bean is that cultivated in the northern districts of the kingdom ; the Tick (2) that in the south. The stem of the (1) Horse Bean is strong, and tall, varying from three to five feet in length ; its yield per acre may be set down at four quarters, the weight at 60 to 65 Ibs. per bushel. The stalk is, in good average growth, well podded to about the middle of its length, the pods containing usually three, but often four to five beans. The bean is larger than the tick, averaging half an inch in length, and three -eighths in breadth. The horse bean grows well on strong well-drained alluvial soils, is hardy, and, as its name imports, is well suited for stable- feeding purposes. The " tick " is a more prolific variety than the horse, although the stalk is shorter, the pods and the beans they contain smaller; it is also better adapted for lighter soils. The " Heligoland " (3.) is a hardy variety suitable for the better class of soils in our late districts. The length of the stalk is shorter than of the two varieties above named, but the seed is about the same size as the tick. The yield may be put down at from four to six quarters, the weight per bushel 66 to 70 Ibs. The winter bean (4.) This bean is being rapidly introduced even into the extreme northern districts; it is hardy, prolific, and is capable of being sown in the early winter or autumn, and being ready for harvesting in July of the succeeding year. Another advantage it possesses, is its apparent freedom from the attacks of the aphides, that scourge of other varieties of the bean crop. The straw or stalk of 244 CULTURE OF FARM CROPS. the variety is from three to four feet high ; the seed is very small, smaller than the tick, but weighs very heavy, 65 to 70 Ibs. per bushel. Mr. Vallentine, in his Prize Essay in the Journal of the Eoyal Agricultural Society on the cultivation of beans and pease states, with reference to the kind or variety of beans he has cultivated, that the horse bean, the " tick," and mazagan are the only kinds he has had experience in cultivating. Of these, he says that he has found the common horse bean suited more for heavy clay soils than for light or loamy soils ; it requires a firm soil, and runs up to a considerable height ; in favourable sea- sons he has found it more prolific than any other. The English and French " ticks, '; Mr. Vallentine says, he has found to thrive best upon light soils ; they grow less straw under similar conditions, yet the grain per bushel weighs some pounds more. On foul land, he says, it is better to grow the " tick " variety than those varieties which run more to straw. Of the winter beans, the French and Russian are those of which Mr. Vallentine has had ex- perience, and of these he prefers the Russian as being rather larger in size, and affording a heavier yield per acre. As to the comparative merit of the winter and spring- varieties, this authority states that he sees no decided advantage in sowing winter in place of spring beans. But when the condition of the labour or work of the farm admits of it, he would prefer to sow winter beans ; at the same time he would not interfere with the sowing of the wheat, in order to get the winter beans in. In any case, he says that winter beans should never be sown unless the land is clean, or nearly so, as the autumn ploughing assists the spread of couch, much more than if ploughed for spring beans at a later period of the year. Mr. Crother, in his Prize Essay in the Journal of the Bath and West of England Society, gives some interesting information as to the intermediate mazagan and the long-podded varieties, Windsor and the like. Of the mazagan — so called from the Portuguese settlement of that name, on the Morocco coast near Gibraltar — he states that it is hardy, well THE BEST SOIL FOR BEANS. 245 flavoured though small. Of the Lisbon, a variety like the mazagan, that it is well flavoured and very fruitful. The long pod is, he says, perhaps the greatest bearer of all ; it grows about three feet high, is hardy, and of easy cultiva- tion. The Spanish bean, otherwise known as the broad Spanish, is a large bean ; it excels in fruitfulness, as does also the Sandwich bean, which, although large, is not a delicately tasted bean. The white blossom, so called, as it does not bear the black velvety spot referred to as a characteristic feature of the bean flower, is good and hardy, although liable to degenerate ; it is very late, and may be sown even at the beginning of June. Of all the large varieties, none are so highly esteemed as the Windsor, "long celebrated for its richness." The varieties best adapted for an early crop are the mazagan and the Lisbon, they may be sown in October, or early in November. In procuring seed, that brought direct from Lisbon late in the season should be preferred, as it will be more fruitful, and produce an earlier crop than the seed grown at home. Mr. Crother notices one variety, the green Genoa bean, of which he says a peculiarity is, that " if permitted to be perfectly ripe before they are pulled, and then be well dried, they may kept in green condition for winter use ; and if steeped for some days before they are wanted, they will become tender, and retain their colour and summer flavour." 42. The soil best suited for the bean crop, is a strong, rather moist one, firm in texture, yet so as to enable the plants to send their roots deep into the soil. Lime is an essential element in it. 43. As regards the condition" of the soil necessary for the bean crop, Professor Tanner, in the able papers to which we have, in the course of these chapters so frequently re- ferred, states— that it requires a soil of a strong and ad- hesive character; and this as much in fact for the sup- plies of food which it draws from it, as from the mechanical qualities which such a soil offers to the plant. Like the wheat crop, the bean requires a firm condition of land, the 246 CULTURE OF FAKM CROPS. roots enabling it to penetrate deeply into, and take hold of the soil ; hence the necessity there is for allowing the soil to get well settled after it is cultivated, before the seed is put in. To secure this, the land should be ploughed early if possible, this giving a freeness to the upper sur- face essential for a seed-bed, and yet the solidity from settlement above alluded to. The bean crop is almost always taken from com stubbles ; this should, if possible, be cleaned in the autumn, and the manure should then be spread over the surface, ploughed in as deeply as possible, and left very rough. In this condition it may be left till spring time. Some prefer the manure to be spread — well rotted — early in the spring, and then to be ploughed in ; but the Professor states that this does not suit the crop so well as the plan described above, as the land by the latter mode does not have time to settle, and the land below gets too consolidated from the absence of the manure during the winter months. Should the land not be prepared dur- ing winter, the seed is often ploughed in without the fur- row slice being broken. The period of sowing extends over February and March. The earlier, however, the seeding is got through, the better for the crop. When the beans are well up, the use of the roller is deemed advis- able to consolidate the soil, and secure a vigorous after growth. The quantity required in sowing by the drill is four bushels the acre. In sowing the winter crop, the ploughing should be finished by the middle, or at the latest, the end of September, and left a month to settle and consolidate ; the land being required in the firm con- dition already alluded to for the winter sown, as well as for the spring sown beans. When the ground is firm, drill the seed, and at wider intervals than used for spring sown beans. For the latter, Professor Tanner prefers in- tervals of 24 or 26 inches between the rows ; double rows at 6 to 8 inches being used, thus — i 8" 26" 8" 26" 8" — !£! — 6" 24" 6" SOIL SUITABLE FOR BEANS. 247 44. While pease, as we shall afterwards see, are grown upon light, beans are grown upon heavy soils ; and if upon light, only as catch or stolen crops. In growing them upon heavy soils regularly they form part of the rotation, as thus — first year, fallow, dunged for wheat ; second year, beans ; third year, fallow again. In the excellent essay by Mr. Vallentine, already refered to, there are some valu- able remarks on this part of the subject, that we here give a resume of them. Such, as above stated, was the almost universal custom of cropping heavy soils, in which beans formed a constant part of the rotation. The wheat was sown broadcast, or ploughed in, the beans treated the same way, and neither wheat nor beans ever received any hoeing or weeding, so that the filthy weedy state into which the land rapidly got may be easily conceived, and even in this day, where the system is still pursued, may yet be witnessed. Mr. Vallentine states that this system was very generally practised some years ago in Huntingdon, Berkshire, Bed- fordshire, and Buckinghamshire ; but that now, under the exigencies of another system, the naked fallow is rapidly become more and more rare. Mr. Vallentine's own ex- perience has shown him that it is quite possible to banish the naked fallow altogether from heavy stiff clay farms, and yet keep the land clean and free from weeds. The rotation he has found best for such soils which are unsuit- able for " roots," or at least unsuitable for thin, easy, and profitable culture, is as follows — first year, beans, dunged ; second year, barley or oats, with seeds (grass) ; third year, seeds, one or two years according to circumstances ; fourth year, wheat. This being changed into a fifth or sixth course, and alternating oats for barley in the second year. By adopting this rotation, the land can be kept clean throughout the whole of it, and in about the same condition for each crop. The wheat and the bean crops require to be drilled and thoroughly hoed, so that the land is left clean for the barley and the seeds ; the grass land resulting, being of course broken up for the fourth, fifth, or sixth year's crop, which is, of course, wheat. On land of a 248 CULTURE OF FARM CROPS. medium texture, Mr. Vallentine prefers to take a bean or a pea crop only every second course, as a substitute for the roots which are taken in the first course, the object being to save manure by curtailing the extent of the root or green crops ; the pulse (bean or pea) crop having thus no manure, but following the wheat, oats, or barley, as the case may be. 45. Land intended for pulse crops should be ploughed as early in autumn as possible, and the drier the soil is the better ; the heaviest lands should be taken in hand first. Where the beans follow a grain crop, the manure should be spread upon the stubble during the winter; the carting of the manure can easily be done without injury to the land. This laying of the dung on the surface to lie for weeks before it is ploughed in, is one of the disputed points in modern farming; but it is right to say that opinion is becoming very generally held that it is a good plan. Professor Yoelcker maintains that there is no loss of manurial substances ; Mr. Baldwin, on the contrary, maintains, or at least did maintain, that there is. On this point, Professor Donaldson refers to the practice often dis- played in East Lothian, where the manure is spread along the furrows, or deposited in heaps at intervals, and in this way exposed for weeks to rain, wind, and sun, till it is apparently washed, bleached, and dried ; and yet the crops are equal to those obtained by the usual mode of covering the dung, and even in some cases a certain superiority for the crops has been claimed; many years, says this author- ity, have tested the matter, and, " however much it may clash with the doctrines of chemistry about exposure and loss by evaporation, such facts are stubborn things." We have seen however, above, that chemistry, as expounded by Professor Voelcker, is in favour rather than otherwise of the exposure of the dung. The practical authority in the Journal of Agriculture we have already quoted, is decidedly in favour of the system of carting on the manure to, and spreading it over the stubbles in winter, and ploughing it in. He says, that when so applied in winter PREPARATION OF THE SOIL. 249 and ploughed in, the dung acts to the best possible ad- vantage in every respect, on all but the wettest and un- drained soils. The manurial substances are absorbed by the soil as the manure decays, rendering also, the heavy soils porous, by the mechanical admixture of its heavy portions. Moreover, by the application of dung at this season, the manure is so tempered that the forcing of the plants which, an authority says, results from mixing the fresh manure with the newly ploughed land in spring, is avoided, and by avoiding this, disease in the crop is not so likely, he thinks, to take place ; he believes, therefore, in the "innumerable advantages of winter dunging." The great aim in carrying out a rotation in which the naked fallow is dispensed with, and a succession of crops with the bean as one of them, kept up and taken off heavy stiff soils, is to keep them clean. To ensure this, the grain crops preceding the bean should be well drilled, so that horse or hand hoeing, or both, can be done. The beans which follow are, of course, to be hoed also, the distance between the rows to be regulated according to the condi- tion of the soil. Beans, by a proper system, can be very successfully cultivated as a cleaning crop for heavy soils, however much opposed may be the opinion of some that they cannot. Mr. Valleritine's experience shows that they can. The first step in his system is to plough the land as early as possible in the winter, and if this is properly executed, no other ploughing in spring will be necessary ; on the contrary, it may not even be advisable. In place of a second, or spring ploughing, a simple scarifying is all that is needed, and will be found to move the soil effec- tually where the ameliorating influences of the weather have not penetrated to the depth of four or five inches. Even this scarifying, Mr. Vallentine has not found neces- sary, as a working of the heaviest harrows has done all that was required. The object in view in reducing the soil to a proper tilth, is to allow the plants to derive the greatest possible amount ' of nourishment from the soil during the period of thin growth. Our authority is not, 250 CULTURE OF FARM CROPS. however, an advocate of the system which aims at getting a very finely pulverised condition of soil in spring, before the sowing of the seed ; on the contrary, he prefers to get the beans a first start in medium soil, reducing it after- wards by subsequent cultivation ; thus at once getting fine tilth, and clearing of the weeds. He deprecates as " most injudicious," the ploughing and scarifying the land to excess in February, for the purpose of pulverizing the land, as the same object can be secured, and better secured, after the plants have fairly come up. Great loss arises from the padding of horses' feet in spring, when the dry weather which generally follows renders land cloddy and quite unsuited to hoeing and weeding. Mr. Vallentine is no advocate for hand dibbling of beans at so much per peck; as it is done generally in so slovenly a manner as to cause the beans to come up in such crooked, uneven l,jnes, as quite to prevent hoeing being properly carried out. He drills his beans in straight lines in spring before the harrow is worked over the land, and across the furrows or at an angle, so that the drill itself breaks up the land ; the seed being deposited at a depth of four inches, but not less than three. The land is only harrowed once after the beans are drilled, should it not be dry enough to admit of the whole harrowing being done. In very stiff clays, it sometimes happens that the soil becomes all at once finely pulverized as the beans come up. In this case the use of the roller is to be recommended, as it levels the land and prepares it for after harrowing and hoeing, Some object to this rolling of heavy land, but Mr. Vallentine has found it beneficial in circumstances as above stated. The same authority believes that beans are much improved by being harrowed about a fortnight after they have come up. If they are very thick on the ground, one harrowing may be given in one direction, another across the rows. This will be found very effectual in tearing up the weeds between the plants. Let it be borne in mind, however, that no harrowing should be done in a^frosty morning, nor, indeed, says an authority, any other kind of cultivation. As soon HOEING OF THE BEAN CROP. 251 as the beans have got above ground three inches or so, let hoeing be begun ; the sooner this is done indeed the better after the plants are fairly and sufficiently up. The earlier the hoeings and the more frequent they are the cheaper each is, the land is kept cleaner, and by conse- quence the value of the crop is increased. It is, says Mr. Vallentine, a great mistake to send one or two labourers into a field, to clean it after the weeds have grown above the plants. It would be well if many farmers would bear in mind what he further says, that if hoeing is not done at the right time, there is a " certain useless expenditure of labour." The longer the surface of the land is allowed to remain untouched, the harder it becomes, and the greater is the difficulty to break it up and get the weeds out. True as this is, however, it should not be forgot that it is equally silly to hoe in wet weather. This only increases the evil, for not only can the weeds not be got up when the soil in stiff heavy clays is wet, but when dry weather sets in, the land disturbed by the hoe gets into such a hard cloddy condition that after-hoeing cannot be done, or if attempted, not done well. All these considerations point to the imperative necessity there is for the farmer to study well the weather, and to lose no opportunity of doing what ought to be done. Let this in the duty or art — for it is an art, as all know who have tried it practically in the field — of hoeing be remembered as an axiom, that the weeds should be kept down by hoeing before they have got strength. But it is better in fact to keep them down, as Mr. Vallentine says, by hoeing " before they can appear, rather than to kill them when they have attained a certain strength." In no department of farm labour is the force of the proverb so apparent as in that of cleaning land from weeds, — " a stitch in time saves nine," " one year's weeding saves nine years' seeding." Mr. Vallentine says, and says, we are sure, with perfect and suggestive truth, that he never regretted hoeing any crop too soon, but that many a time he has felt the loss arising from delay. Hoeing by hand is esteemed the best, but it must be well done, and to eri- 252 CULTURE OF FARM CROPS. sure this, the labourers must be well looked after, — for shocking work is as often done in the field as it is in other places. Garrett's horse hoe is a useful implement, but it should be used before the weeds get so strong and long as to become entangled in and among the hoes. One au- thority states that 8 to 10 acres per day may be ploughed easily by this machine, but when the ground becomes hard and very weedy, its use should not be attempted. The common iron plough, with its mould-board taken off, will be found a very useful implement for hoeing between the rows ; doing one row at a time is perhaps the easiest way in soils very stiff and apt to become cloddy and hard on the surface. Mr. Vallentine gives the statement of ex- pense of cultivating the bean crop on his system, which it is well to give here. One ploughing in Autumn, (cost per acre) . £0100 One drilling in Spring, Three harrowings, One rolling, if necessary, ". 006 One harrowing after the plants are above ground, Sometimes two harrowings, . 006 One horse-hoeing, say on an average of seasons, by the common hoe or plough, three acres per day, per acre, 018 Two hand-hoeings, just beside the rows, 050 One more horse -hoeing, if necessary, 018 Total cost of cultivation per acre, . 144 46. Mr. Vallentine states, that by this system of culti- vation the land has always been kept clean, and that the crop has always been better with much hoeing than with little. By the still not uncommon mode of culture of the bean crop, the following is the expense per acre : — One ploughing in winter, .... One ditto in Spring, . One scarifying, Four harrowings, Two hand-hoeings, say only , , 076 1 13 0 Cost of cultivation by judicious management, 144 In favour of modern system, . . • 088 PERIOD OF SOWING. 253 47. Such an account, says Mr. Vallentine, "is partly im- aginary and partly true, as where the horse-hoe is not used in many instances after the sowing of the seed, the pre- vious cultivation is the same as the system recommended. On the other hand, instead of 7s. per acre being paid for hand-hoeing, more than double that sum is paid for hoe- ing and weeding together : and after all the land is left in a filthier state after the crop is harvested than before the seed is sown." 48. We have already described the different varieties of beans used for seed on farms, and to what we have said, we have now to add, what is indeed most important to be attended to, namely, that the seed to be chosen must be true to its variety and of the best quality, sound, and free from disease. Let not the farmer run away with the notion that any kind of seed will do ; on the contrary, let it be retained in his memory, as a maxim indisputable, "bad seeds, bad crops." As with other crops which we have described, so with the bean crop, — change of seed is good ; that is, the beans raised in one locality may be sown with advantage in another. In all cases, it is essen- tial to have seed which has been properly ripened. 49. The period of sowing spring beans extends from the middle of February to that of March ; winter beans from the end of September up to the middle of November ; but, as Mr. Vallentine says, the earlier the better. The same authority states that spring beans may be sown from the middle of January to the middle of March ; and that it is better to sow any time in February, when the land is in good condition, than to sow earlier when it is not. Professor Wilson says that for winter beans the early part of October is probably the best, as for spring beans February is the best. By the choice of October for the sowing of winter beans the stubbles of the preceding green crop will have been ploughed and well cleaned ; points of vast importance in the bean crop. In the sowing of spring beans, the first fine weather after or about the middle of February should be taken advantage of to get the seed in, for, as well re- 254 CULTURE OF FARM CROPS. marked by the authority above quoted, " the bean plant requires from six to seven months to complete its growth, and if the period of sowing is delayed, the harvest opera- tions are necessarily kept back at a period of the year when each day's delay renders the season less adapted for the purpose, and the stocks are frequently injured before they can safely be carted off the field." 50. With reference to this point as to the best time of sowing beans, does it not, may we ask, appear a strange thing that with all our Agricultural Societies, — National and District — we are in possession of no well -defined trustworthy results of experiments carefully carried out to decide it 1 But we have said so much in previous articles as to the apathy of our Agricultural Societies on points connected with the culture of our crops, that we need not take up space here by saying more ; if, indeed, saying more would be productive of any utility, which we are shrewd enough — however uncomplimentary to the power of the press it may be — to know it would not. It is easy enough to talk of the red tapeism of our Government ; is there none of the disease existing amongst the officials of our Agricultural Societies 1 Ee this as it may, and pos- sibly to their minds it is a matter not worth a rush, the fact is patent enough that, save what we learn from the experiments of Arthur Young — now very old, save the mark, what a pun! — we know nothing as to the relative value of different periods of sowing. It will be well to note here the results of these experiments. Of seed sown in November the produce was 4 '00 „ December, „ 3 '4 2 „ January, „ 4 '42 „ February, „ 4 49 March, „ 4'00 „ April, „ 2-1 „ May, „ 1-42. 51. The quantity of seed per acre to be sown varies with various districts, condition of soil, climate, &c. ; so that the remarks we have had to make in connection with MODES OF SOWING BEANS. 255 this department of other crop culture, we have again to repeat, that no rule can be given applicable to all cases. As a rule 2£ down to 1-J bushels per acre may be taken as the quantity of winter beans required ; while for spring beans from 2 to 4 bushels per acre will be required. The poorer the soil the greater the quantity of seed required. 52. The modes of sowing the crop, like those of the wheat crop, are three in number and the same in character, 'namely, broadcasting, drilling, and dibbling. Of the first of these it is scarcely necessary to state that, with a crop such as the bean, which in one sense is a foul growing one, it is bad, as where it is adopted it is quite impossi- ble to keep the growing crop from the weeds which so rapidly encumber it. Drilling is done by the ordinary grain - drilling machine, but with the coulters and seed- spouts made adjustable, so that the necessary distances between the rows may be obtained easily. They should be adjusted to sow the seed at a depth of not lees than three inches, but nearer four in the majority of soils. In Scotland, and also in many parts of England, drilling of beans is effected by the " bean barrow," doing one row at a time. Dibbling is usually done by the hand, and in a very primitive way, — a stick dibble being used to make the hole, and the seed dropped in by hand. The work is often done by women and children, and almost always done in a careless slovenly way. The system of getting the work done by paying so much per bushel or peck dibbled in is obviously most absurd, and calculated to leave the way open for all sorts of cheating careless work. Mr. Vallentine on this point says, that those who adopt this plan " not only encourage dishonesty, but put a complete check upon cheap and perfect cultivation afterwards." The same authority states that the opinion so generally held in favour of dibbling, arises from a mistaken notion as to its value ; he says that he has had both drilling and dibbling done alternately in different fields for some years, and that he never found any difference in the crop but what could be traced to the work in either case not having been properly 956 CULTURE OF FARM CROPS. performed ; and further gives it as his opinion that "neither the drill, the dibble, nor the men who use either can ex- ercise any influence over the crop after the seed is sown in a proper manner." We are by no means disposed to ac- cept this dictum as the right one. What is the proper manner of sowing the seed 1 it may be by the system of drilling, or, perhaps, by that of dibbling ; it is probable that one is better than the other. There is no doubt that one way of sowing seed — any seed — will be done in ac- cordance with the habits of the plant than another. To say that all plans of sowing are alike good is not borne out by analogy or by facts, so far as we know and are pos- sessed of them. As dibbling seems, for instance, to be the best mode of sowing wheat, inasmuch as it favours the after development of the plant more than any other, so do we incline to the opinion that it is equally the best way to plant the bean seed. Certainly experiments which we have made in the field all go to favour this view, and there was no difficulty in telling which was the best crop, the drilled, the dibbled, or the broadcasted. So far then from agree- ing with Mr. Vallentine that the mode of sowing can ex- ercise and does not exercise an influence in the after growth of the plants, we believe that it does exercise an influence, and an important one. Which of all the three ways of de- positing the seed is the best, absolutely we are not prepared to say, further than we conjecture that dibbling is the best; but still all circumstances of culture incline us to believe that in this, as in other departments, the three degrees of comparison exist, good, better, best. It would not form a useless kind of inquiry on the part of the Agricultural Societies of the Kingdom to ascertain which is the best. 53. The broadcast system of sowing beans being put out of court as, by almost universal consent, the worst mode of sowing beans, and the drilling and dibbling retained as the two best, the question arises what are the best dis- tances at which to sow the beans, that is, the distance be- tween the rows. We have already pointed out Professor Tanner's views on this point; but we may say, what many DISTANCES BETWEEN THE ROWS OF BEANS. 257 of our readers doubtless are well acquainted with, that the greatest possible diversity of opinion exists as to the width between the rows of beans. Some advocate exceedingly wide intervals between the rows, as much as from five to six feet ; others maintain that the closer the distances be- tween the rows the fewer are the weeds, and the less vigorous their growth. A very usual distance between the rows in the districts — and we may say that they are the most advanced in practice — where the bean crop is looked upon as a fallow or cleaning crop, is twenty-seven inches. The advocates of the wide intervals insist upon the im- mense advantages of permitting free access of atmospheric influences to all sides of the plant ; and they say that this is obtained best by wide intervals. We have tried almost all possible combinations of intervals, and we have come to the conclusion that the width of three feet between the rows, and where the two central rows, eight inches gives excellent results; the arrangement is as follows — 3 feet. 3 feet. Still more remarkable results have been obtained by grow- ing the rows a less distance apart, 27 inches, but with all the rows single, thus — 27 27 54. By this arrangement both sides of the plants in the rows receive the full influence of light and air. In some beans we grew upon this plan, the podding was something very remarkable, and all the more so, when compared with the double-row system, and still more so, when compared with the three-row system. Thus, in the two-row system, the outsides, as a b, c d, get the chief supply of light and air, the inner sides getting much less, and this in proportion the closer d the rows are to each other. Make the 258 CULTURE OF FARM CROPS. and it is quite obvious that a I gets comparatively mospheric influences. If the astonishing efficacy ply of light and air in bean plant, let him sow b rows three thus, the central row little of the at- any one doubts of a proper sup- raising the produce of the a patch of this shape abed, and the interior space broadcasted ; he will find that while the interior plants will grow apparently as vigorously as the exterior ones, the podding will be confined almost entirely to the outside plants in the lines a b, c d, d c, c a. Some successful growers have made the distance between single rows five feet, and have been perfectly well satisfied with the results. Perhaps the most complete, if not the most satisfactory, experiments referring to the distances to be given to the rows of beans, were those carried out by Mr. George Hope of Fentonbarns, of which a very full account will be found in the Transactions of the Highland Society for July 1859, and to which the reader is here referred ; content- ing ourselves, by here simply stating, that of the three widths, 8-inches, 16-inches, and 27-inches, the medium width, 1 6-inches, gave the best results ; the space between the widest rows being a mass of weeds, those between the narrower rows being remarkably free from them. Where dibbling is resorted to, another question arises, and like many others connected with the practice of agriculture — it is a disputed one — and it is, what should be the distance be- tween the dibbled pockets or the beans in the rows 1 Nine inches is a very usual distance, and we have found it gwe good, we may say the best, results. Others, again, while advocating very wide intervals between the rows, advocate the utmost possible degree of thickness of seeds in the rows. We have tried this close seeding in the rows, but did not find the result at all equal to that obtained by dibbling them at 8 or 9 inches apart. Nor need we be surprised at this, seeing the superior position of the dibbled DIFFERENT PLANS OF SOWING BEANS. 259 plants relatively to one another, securing to each plant abundant supplies of light and air. 55. With reference to the practice of different districts in sowing beans, Professor Donaldson, in the Prize Essay on beans and pease in the Journal of the Bath and West of England Society, has some interesting remarks, of which a resume will be useful here. On the Plastic and London clays, broadcast sowing of the crop is imperative, the waxy tenacious nature of the soil preventing all drilling and dibbling being properly or economically done. The crop is thinly planted, and the cleaning is effected by hand- hoeing while the plants are not high ; open furrows are left, which renders the operation of hand-hoeing more easy. On soils of this description, beans are introduced after a wheat stubble, and followed by a crop of oats, then comes a fallow ; by this arrangement the clover crop is taken once only in the eight years, in place of once every four. The farming in such soils as those now under consideration leaves, and it may be said, keeps the land foul arid most displeasing to the eye of one accustomed to another and a better system. The plants being thinly set, the ground is exposed, and becomes rapidly dry and parched, arid hand-hoeing, such as it is, rendered difficult and uncertain, weeds are therefore got rid of with difficulty, if at all, and many grow up to seeding. In the best classes of viscous clays of this sort we art now considering, when the original deposits are mixed with chalk and chalky marls, the soil is capable of bearing a thicker set crop which proportion- ately keeps down the vigour of the weeds ; nevertheless, even in such lands the farming is foul enough. On the pure clays first named, the average return of the bean crop is 16 bushels per acre ; the return on the modified clay mixed with chalk or chalky marl at 24 bushels. On the pure tenacious clays of the lias, clunch, or Kimeridge for- mation, beans are also sown on the broadcast system, but fairly thick sowing is permissible, which tends to keep down the weeds, and shading the soil, renders it less baked and cracked and more fitted for hand-hoeing. In some 260 CULTURE OF FARM; CROPS. cases a useful purpose is served by ribbing up the land, after being well harrowed, by a small plough, thereafter sowing the beans by hand, which fall into the furrows and are covered by the harrows; hand-hoeing can in this system be well carried out. In the modified clays met with in Essex, which have been washed with fresh water, and in this way divested of much of their usual tenacity, beans are cultivated in rows nine inches apart, from that up to two feet, the seed being dibbled in by hand on the top of the furrow slice, which is made as deep as possible, — a light harrowing covers the seed and concludes the oper- ations. This mode is the first departure from the broad- cast system where soils do not admit of being stirred in autumn or in the spring ; and where the distance between the rows is as great as 18 inches, the crop can be kept fairly clean by hand-hoeing ; but horse-hoeing is scarcely admissible, the hoes not being able to penetrate the soil sufficiently,' hardened as it is from the winter furrow, so that it is difficult to obtain a tilth favourable to absorption and evaporation. Scarifying, however, is useful as an auxiliary to the hand-hoeing, as tending to get rid of the surface weeds. Soils of this class, being well-suited to the bean, give large crops under this system of culture, from 50 to 60 bushels per acre being not unusual yields. 5 6. Where clays, by mixture with chalk, assume a moder- ately friable condition, the land is deeply ploughed in winter and well harrowed, the beans are drilled by a corn- drilling machine modified so as to deposit the seeds deeply, the distance between the drills being from 9 to 1 8 inches ; the seeds are covered by a light harrowing. Another method in such soils is to well harrow them, and then run a light plough up, so as to throw furrows at any desired distance; broadcasting the beans which fall into the fur- rows and are finally covered by the harrow. Both of these modes admit of horse-hoeing or scarifying between the rows in the earlier stages of the growth of the plants, while hand-hoeing can be done. 57. Where lands are so friable as to admit of autumn BEAN FARMING IN THE EAST LOTHIANS. 261 or spring preparation, the application of farm-yard dung, and of wide interval drilling by machine, the perfection of bean culture is met with. As the beans delight in a deep, though firm soil, the stubble is ploughed in autumn as deep as possible, a depth of not less than 8 inches being aimed at. The ploughing covers in the manure which, in a rotted condition, has been laid over the stubble at the rate of twelve cart-loads to the acre. As soon as the weather is favourable in spring, and the land in good dry condition, the land is well harrowed, or ploughed, or broken up by the contrary workings of a grubber. It is then turned over with furrows 27 inches wide, in the fur- rows of which IJie seed is deposited by drilled, and the ridges split by the double mould-board plough, so that the soil is delivered on each side, covering the seed. Or the seed may be sown broadcast, and falling into the furrows, it is covered with the harrow, or by splitting the drills. A light rolling then succeeds, and then a slight harrowing to break up the surface. As soon as the plants are about two inches above the ground, the light plough is sent to take from the sides of the drills a light furrow, reversing it into the hollows. The scuffler is used for the subsequent workings, which are continued as long as the plants per- mit. After each scarifying, hand-hoeing is performed, and this as carefully as possible, not only cutting the weeds on the sides of the drills, but passed between the plants in the drills, so that the weeds are removed and the soil loosened. In some cases the drills are earthed up with a double mould-board plough. This method now described is carried out on the fen lands, and on deep earthy loams ; and forms, says Professor Donaldson, " the most perfect system of bean farming." 58. Perhaps the finest and most successful bean farm- ing is met with in the East Lothians, where, says this authority, " the deep loamy clayey concreted gravels near the town of Dunbar, and the red rolling clays that overlie the trap rocks south from North Berwick, exhibit the cul- tivation of beans in a manner that is (elsewhere 1) un- 262 CULTURE OF FARM CROPS. equalled." Beans here, generally follow the oat crop. On this, farm-yard manure is spread and ploughed in by the winter furrow. The land is then drilled — turnip fashion — in spring, the beans sown and covered by reversing the drills, and the after cultivation effected by the horse and the hand-hoe. In the most recent practice, the land is worked by ploughing and grubbing, the weeds being carefully re- moved; drills are then opened by the common plough, farm-yard dung spread along the hollows, on this the beans are sown by machine, and the drills are reversed covering the seed, a rolling levels the drills, and a slight harrowing opens the surface just before the beans begin to show through. When the plants are about two inches high, the small plough, drawn by one horse, is sent in and takes a deep furrow from the sides of each drill, sending the soil into the intervals. The drill grubber is used to stir the soil afterwards, and hand-hoeing is carefully carried out. In some cases, the drills are earthed up by the double mould-board plough. 59. The same authority, of whose opinions we have just given a resume, has other remarks which it will be useful here to condense. Enlightened practice, he says, recom- mends the farm-yard dung to be used for beans in a highly wetted, yet scarcely putrescent state ; the roots of the young plants delighting to search for nutrition amongst the rank particles, so that while the tap root descends, the lateral fibres receive plenty of nourishment. Top dress- ings of almost any substance are not to be recommended, producing, as they generally do, more top foliage than grain ; this tendency is more marked in leguminous than in grain crops. Dissolved bones, lime, gypsum, glauber salts, com- mon salts, nitrate of soda, and potash, have all, he says, been recommended for beans to be sown on the young plants, and afterwards mixed with the soil by hoeing. Gypsum and lime require a long time for solution, and should be applied to the land before sowing the seed; on the former along with the seed. Lime may be mixed with the soil by hoeing, or laid in the winter furrow or MANURING FOR BEANS. 263 on the surface, and scarified into the soil. Decisive trials are wanting to decide the question between top-dressings of artificial manures and farm-yard dung, which appears, how- ever, to be the true manure for the crop. " Top dressings rather assist a bad, than produce a good crop." Beans are an excellent preparatory crop for wheat, and appear to be- stow greater benefit upon the land, and to take less from it, than any other cultivated crop. But to fulfil these conditions, the land, says an authority, must be well pre- pared, and the crop drilled, carefully cleaned from weeds; or if sown broadcast, thick, so as to cover the soil and shade it. Where the broadcasted crop is thin and straggling, low in stature and puny in growth, the land is exposed and gets hard, rendering not only hand-hoeing difficult, but affording empty spaces in which weeds luxuri- ate. In clays of the poorest kinds which will not admit of thick - sown broadcasted or of drilled crops, beans should be avoided, as they only fill the land with weeds. Beans are often classed as a green or fallow crop, but they are not strictly so, for they perfect their seeds in the same year in which they are grown, and in the rotation of modern systems, a green crop is that which does not perfect its seed in the year of its growth ; and is that which follows a crop bearing its seeds the same year. The beans, nevertheless, cultivated in the improved modes, of more than one of which we have given description, is still a valuable preparatory crop; it admits of a fair amount of stirring and weeding, and the soil is ameliorated by the action of the tap roots which descend into and open it up. 60. We have already pointed out the physical condition in which the soil requires to be for the bean plant ; as re- gards the chemical condition, being what is called a cal- careous crop, drawing much lime from the soil, the great essential is, that the soil should have this lime. Hence, we have seen, that from the soils formed of clay mixed with chalk and sand, the richest crops are obtained ; if, then, lime is absent, or at best but sparingly present, it is ueces- 264 CULTURE OF FARM CROPS. sary that it should be added. Mr. Huxtable recommends an artificial manure in which lime is present, and which is as follows : — ten bushels of lime, two cwt. of super- phosphate, five bushels of salt and ashes. Mr. Crother, in his Prize Essay in the Eath and West of England Society's Journal, states, that if the land has been limed, the farmer had better depend upon some nitrogenous sub-- stance as a top dressing ; and for this purpose, he says, nothing is better than guano, at the rate of three cwt. to the acre. If this cannot be easily obtained, apply twenty or thirty bushels of soot, with three or four bushels of salt. As regards the after culture of beans, all that has to be said is simply this, that on the plants reaching that height which prevents the working of hand or horse hoes, the crop is left to itself to take its chance. What this chance is we shall see, as we now come to describe the " enemies of the crop." DISEASES OF THE BEAN CROP. 61. The first enemy, the attacks of which the bean has to contend against, is the " millipedes," which commence to eat the seed-bean almost immediately after it has been put into the soil. The attacks of these insects are either so complete as to entirely destroy the germinating power of the seed, or to weaken it so much that the plants resulting are weak, and liable either to be killed by frosts, or to be par- ticularly obnoxious to those diseases, or to the attacks of the insects which infest the crop at a later period of its growth. The names of the millipedes who thus attack the seed-beans shortly after being put in the soil, are the latus pulchellus, and Polydesmus compluratus, of the habits of both of which, a full account will be found in vol. 5, p. 228 of the Journal of the Royal Agricultural Society of England. The seed-beans are much more liable to be attacked in cold and wet seasons than in comparatively warm and dry ones. Should the seed-beans committed to the soil fail to be attacked by these millipedes or false wireworms, and make such progress as fairly to appear DISEASES OF THE BEAN CROP. 265 above ground, they have to " cun the gauntlet " of another and a different set of enemies, not less powerful, however, for evil ; these are the " weevils," so-called. The weevils or beetles, belong to the order Coleoptera, and to the family Curculionidse ; and the species which attacks the beans was called by Linnaeus, Curculio ; but it is now, as stated by the able entomologist Curtis, comprised, along with some twenty other beetles, all scourges of garden and of farm crops, under the genus Sitona; the species called, as seen above, by Linnseus, Curculio, is now named Sitona lineata. These weevils or bean beetles, are of the same colour as earth, and this, in conjunction with their habit of falling from the leaves of the plants when disturbed during the day time, and remaining with their limbs folded up quite motionless on the soil, renders it an exceedingly difficult task to discover them at work. They either destroy the plants as rapidly almost as they appear above ground, or erode or gnaw away the edges of those leaves which may have been developed before their attacks commenced. The weevils burrow in the soil during the dark, generally com- mencing their attack shortly after daylight. The. end of March is the period in favourable seasons when the weevils commence their attacks, but more usually it is April be- fore they appear with all their destructive force. Hence may be deduced the practical suggestion, that the stronger we can have the plants at this season, the more likely are we to find them able to withstand their attacks. Com- paratively little is known of the habits of the weevils or beetles ; so that not -much progress has been made in the discovery of a remedy or a means of preventing their at- tacks. From the hard horny nature of the covering of the insects, it is obvious that no external application, made, with a view to destroy them, could be made without also destroying at the same time the plants upon which they feed ; hence the only resource left open to us is rendering their food so unpalatable to them by some simple applica- tion to it, as to drive them, as Mr. Curtis says, " to forage elsewhere." This is done by dusting wood-ashes, soot, or s 266 CULTURE OF FARM CROPS. lime over the plants early in the morning when the leaves are damp or wet with dew. Our readers may remember, perhaps, that Mr. Fisher Hobbs recommended a similar remedy for the prevention of the attacks of the turnip in- sect, or fly. Mr. Curtis also points out how a catch crop may be made by leaving some of the rows undusted, and when the weevils rush to these in numbers, as to new feed- ing grounds> and their presence is made thoroughly mani- fest by the erosion of the leaves, the whole army of insects might be destroyed by pouring boiling water over the plants, thus saving the general crop. The same authority also mentions the fact of a very eminent agriculturist hav- ing with great success adopted the plan of harrowing or hoeing the plants, doing either the one or the other of these whilst the dew is upon them, so as to cover the leaves with soil, and thus destroy the feed of the weevils. 62. If the plants escape the attacks of the millipedes or the weevils, and reach the more mature stage when flowers appear; with these also, appear other insect enemies — the " humble bee," and the " aphides or plant lice." Bees are often quoted as friends to man, bearing the pollen of male plants to the ovaries of female ones, and thus render- ing them more prolific ; while this is true enough of them in some, nay, in many cases, it is not so in the case of the bean plant. The bean flowers are greatly injured by the humble bees — order " hymenoptera," family " aphidae," genus "bombus," and the species "bombus terrestris," and "bombus lucorum" — which operate upon them "by puncturing the $ase of the flowers, and rendering the incipient pod en- tirely, or partially abortive." The cause, says Mr. Curtis, of the humble bees" " thus damaging the crops of beans and flowers, arises possibly from some unusually large females — for individuals of the same species vary greatly in size — not being able to creep into many flowers that are too small to admit of their bodies, and too long to allow of their reaching the nectary with their tongues ; they are not, however, to be thus balked of their feast, and in- stinct directs them to the exact spot on the calyx, beneath DISEASES OF THE BEAN CROP. 267 which the nectar is stored, there they nibble with their strong jaws until they are enabled to introduce their pro- boscis, and obtain the desired treasure." Humble bees form their nests in old walls, and amongst heaps of build- ing rubbish ; they collect moss in summer time for the making of their nests, and the females come out in spring to collect the honey and pollen. The destruction of the bees, if desired, should thus be carried out in summer. The bees have many enemies, as the " butcher bird," amongst the feathered tribes ; and the fly " volucella inanis ; " and the caterpillar of a moth " ilythia colonella" amongst in- sects -, of these, the latter is the great destroyer of the bees. 63. The great insect enemy of the bean crop in its later stages of development is the aphides or plant lice ; these be- long to the order "homoptera," family "aphides," genus " apis," and species vicia faba — vulgarly known as the Collier fly, the black fly, or the black dolphin. The appearance of these minute insects is generally very sudden, and their ravages not only complete, if not arrested, but remarkably rapid. By very fortunate circumstances their presence is easily detected, and this not only from their intensely black colour, but from their always appearing at the upper part of the plant. To meet the attacks of this insect, the farmer has fortunately a remedy not only easily carried out, but most effective ; this is, " topping the plants," either cutting them off by means of a scythe, a sickle, or by hand. Care should be taken to carry out this remedy on the very first appearance of the insect ; hence the neces- sity of a watchful supervision of the bean field ; and further, to destroy the cut-off heads either by burning them, which is the best method, or by crushing them into the soil with the foot as they are cut off. The insects or lice are eaten in immense numbers by the calling birds, and their black larvae by ichneumons and maggots of dipterous flies; but while the number of the aphides may thus be kept under by these their enemies, it is doubtful whether this conduces to the safety of the~crop, inasmuch as the remedial measures, if they are designed to be per- 268 CULTURE OF FARM CROPS. fectly efficient, must be taken at the very earliest stage of the attacks of the aphides. 64. Beans are also subject to the attacks of another species of beetle, named, but named erroneously, " bugs." These belong to the order " coleoptera," family " bruchida?," and genus "bruchus," so called from their "destructive nibbling propensities." The eggs of the insect are deposited in the flowers of the bean, and the maggots resulting from these eat their way into the seed. Before changing into the pupa? condition, the maggot eats a round hole from its cell to the rind of the seed ; the rind at this part is also probably " partially cut through," so that when " the beetle " is ready to come out of its cell, it readily forces itself through the rind. Fortunately the maggots do not destroy as a rule the germ of the seed, although often they do so com- pletely eat all the interior that nothing is left but a hollow case or rind. To kill the maggots, therefore, the beans used for sowing are recommended to be steeped in brine or in hot water for a minute or so before sowing. Mr. Curtis states that " seed should be examined before sow- ing, and the infested beans may be detected by dull cir- cular spots in the skin, where no holes are to be found." Another insect which attacks beans, in common with corn and other vegetables, is the " mole cricket." This belongs to the order "orthoptera," family "achetidse," genus "gryllo- talpa," species "gryllotalpa vulgaris." Residing under the sur- face like a mole, it burrows horizontally, and has astonishing muscular powers. It commits its ravages upon the crops in the night. The only plan recommended to the farmer on the large scale, is that quoted by Curtis as adopted by Kellar — " when there is a flat area of 500 or 600 yards, dig three or four pits in September, 2 or 3 feet deep and n foot wide* then fill them with horse dung and cover them over with earth. Attracted by the warmth, all the mole crickets will resort to those pits from the surround- ing neighbourhood on the first frost, and may then be easily destroyed." It is a singular and fortunate circum- stance that, although most prolific, their disposition is so THE PEA CROP. 263 ferocious that the mother devours nine-tenths of her off- spring. The " mole " is also one of their greatest enemies. Their presence in soils may be detected by the little heaps of earth thrown up by them in their progress. 65. While, as we have shown, a good deal is known as to the habits of the insect enemies of the bean crop, little comparatively is at the service of the farmer as to its dis- eases. The plants are liable to be attacked by a "parasitic fungus" termed mildew, this being more the case when sudden variations of temperature act in con- junction with cold and wet weather, and in cold, un- drained, heavy clay soils. A " fungoid disease," which has been recently attacking the bean crop, will be found very fully described by the eminent entomologist, the Kev. M. T. Berkeley, in the Agricultural Gazette, p. 677, vol. for 1859. The leaves are covered with red and brown and si} u ff- coloured blotches, which are, in fact, due to the "uredo fabse." The plants sometimes recover from the at- tacks of this disease even after it has been so far developed as to give the crop " a very wretched aspect." Another disease has been described by the same authority as affect- ing the pods of the bean. Although at first it is confined to the surface of the pod in the form of a scab or pustule, it has been found to eat its way through the pod and attach itself to the seed, which becomes deteriorated in value. CHAPTER SECOND. THE PEA CROP. 66. THE Pea crop next claims our attention. Like the bean, it belongs to the class of dicotyledonous plants, and the order Leguminosce,. The family is Pisum, and is, like the bean, classed into two kinds, — the field pea, or Pisum sativum arvense; and the garden pea, Pisum sativum 270 CULTURE OF FARM CROPS. hortense. As regards the history of the pea, we may state briefly that it was well known to the ancients, amongst whom, especially the Romans, it was highly esteemed and greatly cultivated. As the bean gave a distinctive name to a noble family of the Romans, so did the pea ; hence the Pisani. The cultivation of the pea was doubtless in- troduced into this country by the agency of the Romans ; if not by them, at least by the people of the Low Coun- tries. It has been a highly-esteemed crop for centuries, and, before the introduction of potatoes, formed a very essential part of the food of the people, so that its con- sumption was much greater then than it is now. The plant, botanically described, has the stipulas rounded and crenate at the base ; the stalks, at the base cylindrical, carry several flowers, white in colour generally in the Pisum hortense, or garden pea, but purple generally in the Pisum arvense, or field pea. The root is annual, slender, and fibrous : the stems are hollow in their first stages — are not strong, but brittle; they therefore do not stand erect, like beans ; they are terminated by fine curling ten- drils, which take hold of and twine round any firmer sup- porting material near them. The leaves are pinnate, abrupt, composed generally of two pairs of leaflets. The shape of the leaf is elliptical, and the surface smooth and shining. The flowers are lateral, and cluster, two or three together, on long, peduncular stalks or stems. The corolla, as stated above, is either white or purple, and sometimes variegated. The legumes or pods are generally in pairs, about two inches in length, of oblong form, pointed at the end, generally straight, but, in some varieties of the Pisum hortense, curved scimitar fashion. The seeds vary in num- ber from five to nine ; they are of various shapes — in some varieties globular or spherical, in some flattened spheres or oblate spheroids ; some approach to the cubical, some to the cylindrical form. The varieties in use for field culture are — (1) the Common Grey ; (2) Warwick Grey ; (3) Hastings Grey ; (4) the Dutch or Giant, also known as the Rounceval, Grey ; (5) Grey Maple, Marl- VARIETIES OF THE PEA. 271 borough, or Partridge Pea. Of these varieties No. 1 is that commonly cultivated. It is very prolific, with a long pod, well filled with from five to eight seeds. It is late in coming to maturity compared with other varieties, ripen- ing about the same period as the bean ; hence, in northern parts of the kingdom, it is sown along with this crop, both being ready for harvesting at the same time ; and the strong stalks of the beans serve as supports for the slender ones of the pea. By this arrangement the produce of the crop is very much increased. The colour of the stem varies, but it is very useful as fodder for cattle. The variety No. 2 of our list is the earliest of the peas fitted for farm culture, being from four to five weeks earlier than No. 1, the common grey — hence its value for late sowing. It does not grow to a great height, or rather to a great length, three feet being the maximum. The pods are short, containing generally from three to five seeds only, the form of which is spherical, sometimes slightly flattened or compressed on the sides. Between Nos. 1 and 2, in point of date of ripening, comes No. 3, the Hastings Grey, earlier than the common and later than the Warwick. Its stem is longer than that of No. 1, and more feeble and slender. It is well adapted for light soils, on which its yield is good. The pods are long, rounded in sections, and generally well filled with seeds, the form of which is circular, with compressed sides. No. 4, the Dutch or Giant Pea, as its latter name indicates, is the largest of our field peas. Its stem grows to a great length, seldom less than six, frequently eight to ten feet. This pea pro- duces its pods in pairs, the form of which is broad and flat. The seeds are usually five or six in number, and of a " dun brown " colour, with black eyes ; they are much flattened in shape, and wrinkled in the skin. No. 5, or Marlborough Pea, is, like No. 2, the Warwick, an early variety, and, like the Giant Pea, is a strong grower, the stems being generally about four feet in length, bearing large broad leaves, and pods broad-shaped. The seeds vary in number, averaging from five to seven ; they ar§ 272 CULTURE OF FARM CROPS. round in form, of a yellow -"brown colour, and having eyes light-coloured. 67. The soil best adapted for the pea is a warm, well- drained, loamy, or marly soil. Like the bean, it is a lime plant, and soils of a calcareous nature are most "beneficial for it. But although the soil is required to be free and well-drained, it must still possess a certain degree of co- hesion and of moisture. Rich in inanurial ingredients it must also be, if productive crops are desiderated. Its roots do not take such a hold of the soil as those of* the bean, hence it may be cultivated in shallower land than the latter crop. From what has been said above, it will be seen that heavy clay soils are not calculated for pease. But when such soils are in good tilth, and in districts gen- erally warm and dry, pease may be, as they often are, culti- vated along with beans ; and clinging as they do to the strong stalks of the beans, the pease yield good crops, and the united produce is more valuable, it is said, than where beans alone are grown. The attacks of the plant-lice, or aphides, are also said to be less severe than where the crops are taken off singly. 68. Pease do not form what is called a rotation crop, being generally taken off stubble or grass layers. • On light soils, by taking pease in place of beans, the clover may come into the rotation every eighth in place of every fourth year, and thus reduce the chances of its being at- tacked with the " clover sickness," if, indeed, which has been questioned, a frequent recurrence of the clover in the same soil is the cause of its failure. On stronger, heavier lands, the pea crop should be placed between two cereal crops, and, according to a high authority, treated as a fallow crop. But great difficulties lie in the way of so treating pease, from their habit of growth. With their long tendrils trailing on the ground, it is sometimes scarcely possible at even the early stages of their growth, quite impossible at their later, to hoe and stir the soil between the rows. But on this point will be found remarks bearing on it at another part of this Chapter; meanwhile we proceed to CULTURE OF THE PEA. 273 notice that some advanced agriculturists are advocating the importance of bringing the pea crop more regularly into the rotation of the farm than it now is. One authority has stated that he has always had the heaviest crop of barley and the cleanest land which followed pease, top- dressed with 2 or 3 cwt. of guano ; while, on the other hand, he found the turnips which were made to succeed pease lighter than when taken after two years' grass. At a time when so much is being said about the clover plant and its sickness, it will be worthy to note here what a practical man has stated the result of his experience to be in the growing of pease followed by clover. He states that in a field one-half was sown with pease, the other with clover ; the whole field was then laid with clover, and the half which had been previously under it was bare, not a head of clover being seen, while the half which had been with pease had a remarkably fine crop of clover. The same authority states that the course of cropping he has adopted where pease or beans came in, is to have turnips and barley or seeds followed by oats, and then the beans or the pease. 69. "When taken on the wheat or the barley stubbles, the land should be deeply ploughed as early as possible, and left to stand all winter. In spring a second plough- ing may be given, but a scarifying or grubbing will in many cases suffice. The surface is then well harrowed, and the seed put in. If farmyard dung is applied, it is spread over the surface, and then ploughed in. Lime, or superphosphate of lime, 2^ or 3 cwt. to the acre, will fre- quently be mixed with the manure with great advantage. Where they are both used, Professor Wilson recommends that the lime should be ploughed in with the winter fur- row, and the farmyard dung spread over the surface in spring previous to sowing, the dung being well rotted. He says, however, and we decidedly agree with him, that it would be better still to reverse the operation as above described, ploughing in the dung in the winter furrow, and applying the lirne or the superphosphate in the spring. 274 CULTURE OF FARM CROPS. 70. Where the crop comes after the corn or grain crop which has followed turnips, the land should be made as clean as possible in the autumn, or if the state of the weather or other causes will prevent this being done, early attention should be given to the spring work of the field, so as to get the land in good heart for the pea crop. The soil should be ribbed some 12 inches or so wide, but the seed may either be sown broadcast or drilled on the flat. The width between the drills varies in practice from 1 8 to 24 inches. In view of the benefits attendant upon the cleaning of the crop during its growth, in the early stages, it is better to err in having the distances between the drills too wide than too narrow. We are inclined to think that, as a rule, the distances are too narrow. But in this, as in other departments of culture, practical men have only to conjecture what is best ; for the experiments, and the care- ful mode of conducting these, which we have in these papers and elsewhere advocated as essential to eliminate practical results in connection with the cultivation of crops, are as much needed in reference to the Leguminosas as the cereals. If it is deemed necessary to apply a heavy dress- ing of artificial manure, it will be advisable to apply it in two dressings rather than in one — half at the harrowing-in of the seed, half at the first or second hoeing. However clean the land may be when the sowing is completed, not long will it be before it is found that it is bearing some- thing more than pease ; and as it certainly is JJie aim of the farmer to make pease the only, if not at least the prin- cipal, crop which the land is to bear, it will be wise on his part to go on, as soon as the drills are fairly up, with the hoeing, this being thoroughly and carefully done. When we see how often a so-called field of pease is as much a field of weeds, we have abundant evidence of the need there is for securing cleanliness of land, and of the reason for the prejudice, moreover, that exists on the subject of pea cul- ture. Not seldom, indeed, do we find that a crop is blamed as the cause of dirty land, when the real nature of the case is that it is the fault of the farmer, not that of the crop. CULTURE OF THE PEA. 275 This is specially true of the bean and the pea crop. While on the subject of manuring and preparing the soil, it is necessary to note that the experience of many farmers shows that it is a somewhat unsafe practice to sow the seed on a newly-manured soil ; inasmuch as the plants are more apt to run to stalk or haulm than to produce seed. When of course the plants are grown, as they sometimes are, to be cut green for fodder in place of vetches, then this plan of sowing en newly-manured soil is beneficial. 71. Where soils are not in good condition it might be well to give them two good ploughings, the first having for aim the cleaning, and this to be followed by a cross- harrowing, the second ploughing to lay the land up in the drills. The drills in heavy soil should not be deep, as the seed is apt to rot ; in light soils the drills should be made deeper. Where the pea crop is taken upon a clover lea, one ploughing is found to be sufficient. 72. The depth to which the seed is to be sown is a matter of some importance : it should never exceed two and a half inches — two inches being, as a rule, a safe depth. 73. In close connection with the point now under notice, we must refer to the difference of opinion there is as to whether the weeds in a field of pease are best kept down when the seed is drilled or broadcasted. One eminent practical authority states that a larger crop will be secured by broadcasting, and of course fewer weeds, than by drilling, because the fewer the wide spaces the less room there is for weeds coming up. On the other hand, if a field is badly infested with weeds — as, say, the wild mustard or thistles, which will come up along with the pease — there can be no doubt of this, that the drilling system affords opportunities of attacking the weeds at the early stages of their growth, which is an immensely valuable feature in the war against weeds. So far as broadcasting is concerned, the thicker growth of the pease which the system secures, seems to act as a preventive of weeds, simply as tending to overshadow or overgrow them. 276 CULTURE OF FARM CROPS. It is a mere question between the vigour of the one or of the other. Not seldom, however, have we seen the ques- tion decided in anything but the most favourable manner for the interests of the farmer, by the vigour of growth being all on the side of the weeds ; in the struggle for existence — a la Darwin — the pease, poor things ! having decidedly the worst of it. On the whole, we are inclined to believe that the balance of evidence is in favour of the opinion that broadcasting gives a better crop of pease than drilling, if the land is thoroughly clean previous to sow- ing. We have italicised the if, inasmuch as on it turns the whole question ; for if the land is not clean, and weeds infest it, the drilling system is the best, as it undoubtedly affords facilities greater than that of any other system for getting rid of the weeds which will come up. 74. The pea crop suffers from the attacks of certain dis- eases and insects. The most common disease is blight or mildew. This arises apparently from a variety of causes, none of which as yet are very well understood j nor have they been, as they ought to have been, investigated by authorities. Doubtless the weather has the most remark- able influence upon the creation of blight. Sudden and also frequent transitions from cold to hot, or vice versa, produce a tendency to blight in other crops as well as in the pea. The soil, doubtless, has also a great influence upon the liability of the pea to be attacked by blight. Thus, it has been observed that pease grown upon heavy clays of the yellow or blue lias formation, have not been so subject to blight as when grown upon calcareous, peaty, or sandy soils. The season or period at which they are sown has also its influence, as indeed has the kind of manure used, and the mode of using it. How suggestive do we thus find the consideration of all departments of crop culture to be ! As to this great truth, that we know comparatively little of what we may call the inner life of those crops — their field habits, and what influences those habits, whether in the modes of culture and treatment, or in the more occult causes arising from climatic or atmo- DISEASES OF THE PEA. 277 spheric changes — we here reiterate what we have often ex- pressed, that our agricultural societies have yet a vast deal to do before they can say they have done all they can do to make known what, for lack of a more suggestive word, we here call the philosophy of our crop culture. What- ever may yet be done by them — " if it were done, 'twere well that it were done quickly " — we will venture to say the most good will be done if they direct their attention to discover, if possible, the causes which predispose crops to be attacked either by atmospheric, vegetable, or animal diseases, rather than to the discovery of a cure or cures for these diseases. To prevent is better than to cure, if, in- deed, cure can ever be successfully carried out when dis- ease in plant life has once set in. We are inclined to believe that prevention is hopeful, cure is hopeless. 75. The insects which attack the pea crop, and too fre- quently rapidly and completely destroy it, are pretty numerous. The seed when fairly in the soil is attacked, or very liable to be attacked, by mice, and by the milli- pede insects. Mice are so fond of the pease that their in- genuity in discovering the locality of their deposit, and their perseverance in getting to them, are something won- derful. One practical man states that he suffered heavily from the attacks of mice, until he adopted the plan of spreading a layer of coal-ashes over the soil where the seed was deposited. Pease have also been recommended to be steeped in coarse train or lamp oil, and by others in coal- tar, before sowing, so as to make them obnoxious to the mice. To prevent them finding out the position of the seed, it will be well to make the surface as uniform in appearance as possible. The attacks of the snake milli- pedes is another cause of the seed being destroyed. 76. Should the seed pass safely through the ordeal which it has to encounter through the attacks of mice or of millipedes, the leaves are no sooner developed than they are in their turn subjected to the attacks of " weevils," of which the species known as the Sitona lineata, or "striped weevil," is that commonly found to attack the field pea. 278 CULTURE OF FARM CROPS. When the weevils appear in large numbers, they soon clear the fields of green. The only curative process — which, although attempted, will also be too frequently curative in name merely — is to brush the surface of the young plants with a light seed or bush harrow when the dew is on them, so as to bring the soil in contact with the leaves ; a soiled or dirty leaf the weevils will not touch. The same effect may also be obtained by broadcasting dried road-detritus mixed with coal-ashes, soot, or with lime. 77. When the leaves are fairly developed, they are often attacked by the larvae of a minute fly, the presence of which is indicated by little " faded patches, with a minute brown speck in their centres." The fly is the same as that which is one of the scourges of the turnip crop, the Phytomoza nigricornis, and the larvae of which feed upon the fleshy parts of the leaves. 78. Should the pea still succeed in passing through these ordeals, the nature of which we have described, and get into the flowering stage, it is here again subjected to the attacks of what is properly called the louse, but scientifi- cally the Aphis pisi, the colour of which is green — that of the Aphis fabce, or bean louse, being black. The same remedy so efficacious in the case of the bean — cutting off the head of the plant — is, from the nature of the plant, not admissible in the case of the pea. Of preventive mea- sures, then, which are all that are left to the farmer for this disease of the crop, many have been proposed. Salt is said to be the best, but it requires to be used with great judgment. Soot also is recommended by some. 79. If, in spite of all these enemies, the pea-stalks should get the length of being podded, the pods themselves form receptacles for the larvae of certain fly scourges. And as the pea itself progresses in growth, it is attacked, or liable to be attacked, by the caterpillar of the moth Tortrix pisana; so that when thrashed out they present the worm- eaten appearance which is as much dreaded by the farmer as the full, plump, sound sample is cherished by him. Should he be fortunate enough to have a good sample of FLAX. 279 this kind to store up, the chances of loss are not yet done with, for the seed is apt to be ravaged by the attacks of the beetle, which is found so frequently destructive to the bean seed, and of which a notice, and the best means of pre- venting them destroying the vitality of the seed when sown, will be found in the chapter on the bean crop. DIVISION THIRD. FLAX. 80. OP what are termed the "industrial" or the "special" crops, as flax, hemp, and the oleaginous plants, space only permits us to treat of the first of these ; and which, when we view it as the source of one of our important textile fibres, is certainly the most important of them. Of our industrial farm crops, flax possesses high claims to a great antiquity, taking precedence of all other crops of this class. Frequent mention is made of it in Holy writ, and abundant allusion is made to it in the writings of profane authors. It formed one of the principal crops, if not the principal of ancient Egypt; the crop was also well known amongst the Greeks and Eomans ; and amongst writers of the latter people, Pliny gives considerable space to a minute detail of the mode of cultivating it. Flax in this country was cultivated from a very early period, and for long was one of the most important crops we possessed. 81. The botanical order to which flax belongs is linece, having three genera, and these having ninety species ; of these the only one cultivated is linum usitatissimum, or common flax. The plant is annual, grows to a height of from 18 to 24 inches, and bears numerous flowers of a beautiful pale delicate blue. The seed pods which suc- ceed the flowers are of five cells, each of which contains one seed. This, of a long flattish shape, and of a dark brown colour with shining surface, contains oil which is 280 CULTURE OF FARM CROPS. known as linseed, and the residue of a mass of which is — when compressed — known as linseed cakes, or generally as " oil-cake." 82. The flax crop is by no means a favourite one with farmers generally, as it is by them — as it was indeed by an- cient authorities — considered to be an exhausting crop. Pro- perly cultivated, however, it is no more an exhausting crop than wheat or barley, and its cultivation is consistent with as good and economical cropping of the land as that of any other crop. As already stated, flax is a special crop, from which it may be gathered that it is cultivated only in special districts. These are chiefly in this country to be met with in Ireland ; and of the best mode of cultivation there adopted, the following will convey a fair idea : — 83. The soil found to be best adapted to the cultivation of flax is a sound, dry, deep loam, with a clay subsoil. As with other crops, draining and subsoiling are essential; good flax cannot be expected where surface or underground waters abounds. The land should be carefully and re- peatedly cleansed from weeds, to place it in the " finest, deepest, and cleanest state." This will enable the roots to penetrate the soil, which they will frequently do to a depth equal to half the height of the plant above ground. On light friable loam, one ploughing after wheat may be suffi- cient, but two will be better ; on stiff soils three are ad- vised, one of these immediately after harvest, across the ridges, the remaining two in spring, so as to be ready for sowing in the first or second week of April Better crops will be obtained, if the land is so worked that the seed can be sown in flats. To give the land time to consolidate, the subsoiling should be done at a not less interval than two years previous to the flax crop. After oats, where thorough draining has been carried out, it will be necessary to plough early in autumn, to the depth of 6 or 8 inches, the land to be thrown into ridges, to receive the frost and air, with surface drains ; to be ploughed again in spring 3 or 4 inches deep, so as to preserve the winter surface for the roots of the flax. This spring ploughing should be FLAX. 281 done some time before sowing, to give time for weeds in the land to spring up, and these, when harrowing in the flax seed, will be killed. To give an even surface, and to consolidate the land, the land should be rolled after the last harrowing ; this to be again broken up with a short- toothed or seed harrow before sowing; this to be up and down, not across the ridges, or angularly. " The seed best adopted for the generality of soils is Riga, although Dutch has been used in many districts of the country for a series of years with perfect success. American seed does not generally suit well, as it is apt to produce a coarse branchy stem ; if used, it should be in deep loamy soils. In buy- ing seed, select it plump, shining, and heavy, and of the best brands, from a respectable merchant. Sift it clean of all the seeds of weeds, which will save a great deal of after trouble when the crop is growing. This may be done by fanners, and through a wire sieve twelve bars to the inch. Home saved seed has produced such excellent crops of late, that it is strongly recommended that every farmer should only sow, each year, as much foreign seed as would pro- duce a sufficient quantity for his flax crop of the following season. (The produce of seed averages about 12$tmshels the statute acre, so that the seed saved off one statute acre will sow about 5.) The thinner portion of the crop would be the best for this purpose, as when flax grows thin it produces much seed. This plan, besides the saving effected in the price of foreign sowing seed, would effectually secure the farmer from any danger of loss from fraudulently made- up seed. It will be best in most cases to use the seed tvhich is saved from this, in the following year, for feeding, or to sell it for the oil-mills, although it often produces good crops. The proportion of seed may be stated at 3J imperial bushels to the Irish, or plantation acre, and so on in proportion to the Scotch or Cunningham, and the Eng- lish or statute acre." With thick sowing, the fibre pro- duced is of greater length and fineness than in thin sowing ; in the former case, the stem grows tall and straight, pro- ducing little seed ; whereas, in the latter, the plant grows T 282 CULTURE OF FARM CROPS. coarse, producing much seed, and a very inferior quality of fibre. To give an equable supply of seed the land should be marked off in divisions of 8 or 1 0 feet broad, if it has been laid without ridges. Cover it with a seed harrow after sowing, and to avoid the small drills otherwise made by the teeth, go twice over it, once up and down, once across or angle wise. Finish with the roller, which will leave the seed covered about an inch, which is the proper depth. This rolling after sowing is much recommended; care, however, should be taken not to do it when the ground is so wet as to cause the soil to adhere to the roller. 84. The ridges should be little raised in the centre when the ground is ready for the seed, otherwise the crop will not ripen evenly. Where it can be dispensed with, it is recommended not to sow clover and grass seeds with the flax, as these plants injure the root ends of the flax. Carrots may, however, be sown in drills where the soil is suitable ; and when the flax is being pulled, the work- people can step over the rows, and afterwards hoe and clean them, finishing with a top-dressing of liquid manure. After
