IT is nearly a year since I left this work with the printer. The first copy of the book which I saw was procured in a foreign land; and now that a second edition is called for, I find myself again in fields and orchards of another country. These per- sonal remarks are not of themselves worth making here; but they shall be my excuse for writing a few contrasts of American and European fruit-growing. Classified in respect to the objects in view, there are two kinds of fruit-growing,— that which desires the product primarily for home use, and that which desires it primarily for market. Of market or com- mercial fruit-growing, there are again two types,— that which aims at a special or personal market, and that which aims at the general or open market. The ideals in these two types of fruit-growing are very unlike, and the methods and the varieties which suc- ceed for the one may not succeed for the other. The man who grows fruits for the special market, has a definite problem. The product is desired for its intrinsic qualities; and special products demand special prices. The man who grows fruit for the world's market, has no personal customer. The product is vi Preface. desired for its extrinsic or market qualities; and the world's products bring the world's prices. The special -market fruit-grower generally works on a small base. The world's -market fruit-grower works on a large base ; or he sells to another who, by com- bining similar products of many persons, is able to command the attention of the market. Now, it is the large base upon which American fruit-growing is established which enables it to enter European markets. In America are thousands of acres of one variety, and the conditions under which the fruits are grown are so similar as to produce uni- formity in the product. We speak one language, and, although we are two nations, we live in practically the same political environment. We go to Europe, and to our own great markets, with wholesale quan- tities. In Europe, on the contrary, nearly every fruit- growing center is unique. The industry is the out- come of years, may be of centuries, of local effort and tradition. There is no general uniformity of methods and varieties. Community of interests on a large base is impossible. There are insurmountable difficulties of physiography, of races, languages and political systems. In the staple products, the Euro- pean grower may not be able to compete with Ameri- cans in his own markets, so long as those markets remain naturally open. The American fruit-grower quickly assimilates new methods. He is unfettered by tradition; and how much this means only those can understand who know Preface. vii the European customs and ideals. He is bold and confident. He easily buys and sells land. He con- trols his own efforts and destinies. He has more help from teachers and experiment stations than the Euro- pean has. A single instance will illustrate all this. Spraying for fungous diseases is a European develop- ment, whereas large -area spraying for insects is an American development. The American has assimi- lated the spraying for plant diseases and has made improvements in the machinery, while he has at the same time made equal progress in fighting insects; but the European has not assimilated the American methods of handling insects, and spraying for plant diseases is probably less generally understood than in America. In manj- parts of Europe, the farmer is a tenant, and he therefore has little interest in planting trees. But even if he owns land, the area is usually small, notwithstanding the fact that there are many very large individual plantations. There are few great geo- graphical regions which are adapted to fruit-growing, or which, if they are adapted, can be utilized for that purpose. The environments of the Old World farmer a IT relatively inflexible. The result is that his methods tend to become stereotyped and rigid. He lacks the inspiration which comes of conditions which are easily recast and modified. His small areas must be so crowded with many kinds of plants that machine- work is impossible. There are few orchards in Europe, as that word is understood in America, meaning an area devoted exclusively to tree fruits set at regular viii Preface. distances and cultivated systematically with labor- saving machinery. For these and other reasons, as well as for the fact that our fruits and their manufactured products are attractive and of good quality, I believe that the American fruit-grower will find an increasing market in Europe. But the greater the quantity sent abroad, the more discriminating will that market become; and it must be true that the brands and the varieties of inferior quality tend to supply the inferior markets. But if I believe that American fruit-growing is in advance of the European in its general commercial aspects, I am equally convinced that the European is in advance in growing for special and personal usas. The narrowness of the enterprises, the competition in restricted areas, the respect for traditional methods and varieties, conserve the very elements which appeal to the discriminating consumer, while, at the same time, they develop great skill in the fruit-grower. The care which is bestowed on individual plants, the niceties of exposure and of training, the patient hand- work, may almost be said to develop personal traits in the fruits themselves. Such fruits may not find a place in the open market, but for that very reason they may have a higher commercial value. At the head of a little valley, closely shut in by the Alps, is a famous apple orchard. The trees are trained upright on the opposite sides of a double espa- lier or trellis, the sides of which are less than two feet apart. In each of these rows, the trees are two to four feet asunder. These trellises are perhaps ten feet Preface. ix the one from the other, and between each two is a row of apples on cordons or single horizontal wires; and in the spaces potatoes or other annual crops are often planted. Even the wires that brace the end posts of the trellises have apple trees trained on them like strands of vines. Each' tree is trained to a definite number of branches or arms, and even the fruit -spurs are carefully determined. This plantation is the property of a company whose business it is to care for the land and the trees, and to find a mar- ket for the fruit. It is expensive to grow apples in this way ; but the best Calvilles often bring a gulden (about forty -one cents) apiece. Perhaps the most important lesson which the American fruit-grower has yet to learn is the fact that there are two types of effort in commercial fruit- growing, and that there may be pecuniary reward in fruits which are unknown in the market. Failure to distinguish these two categories is the result of a con- fusion of ideas. One grows fruit either for a special and personal market, in which case he looks for his own customer and is independent of general trade; or he grows what the market demands, and allows the machinery of trade to handle the product. In the latter effort, the American fruit-grower is preeminent; but in the former he has made little more than a beginning. L. H. BAILEY. BOZKN, TYKOL, May 20, 1898. CONTENTS CHAPTER I.

In order to spread a knowledge of the subject, further studies in the evaporation from winter twigs have been made for me by my stu- dent, A. L. Knisely, M.S.: "In January, 1897, I cut twigs of various kinds about one foot in length, and took them to the lab- oratory. When ready to weigh the twigs, they were cut down to about four or five inches in length, the object of the second cutting being to leave as little time as possible between the cutting of the twigs and the weighing. As soon as the short twigs were cut, they were weighed, and the freshly cut ends were then dipped in melted paraffine, thus sealing the cut surfaces and preventing evaporation except through the bark and buds of the twigs. After dipping in the paraffine, they were weighed again, and then put in places as much exposed as were the trees from which they came ; in fact, in some cases, the twigs were tied on the trees and left there for 72 hours, and then weighed. They were afterward exposed for another 72 hours and weighed again, making a total length of time of 144 hours, or 6 days, that the twigs were exposed. During all this period, the thermome- ter registered below the freezing point. That there is loss of moisture by evaporation is shown by the following table, which gives the data obtained from the twigs of a number of our most common fruit and shade trees: The Principles of Fruit -growing. •os -qaj — -.*\BL[i E jayB jnD s3iMj ui ajnjsioui jo jaaJ «d 'tl 8 OS 5 g OS 1 i •oz -lief— -auizaajj [BnuijuoD jo s.isp [BJaAas jays »nD S^IMJ ui aiajsioin jo juao Jaj •$! a 9 " oi 3 CO •SKVHO— 'SJnoq tz ui SDEjjns jo y -bs jad sso| pajB[no|B3 -gt 1 5 i ? s rr •ua^B) s3i.«j uo aoBjjns jo saqoui ajBnbg 'II s 8 8 ?1 ei i jo aDusjajuinDap'aaEaaAv' '01 ^x^ ^ SOX* ^^ X > 3 3 X XR X3?4? »S^ riT " i -— — -« N . - « - -s^unso,,^., . 5« n a s a •swvao — -saq »z joj ssoi pajEjnDiEO -9 | O I i I s 3 •swvao — -sanoq tti U| ssoi IBJO^ -5 i s i I i h 0 •swvao — 'SJnoq ni jajjB Jn3iaM 't | 5 CD 2 1 i s •Swvao— pauiofqns sso[ qiiM Sjiiot[ zL jayB )q3ia^ *f i 11 ri • || Ji §3 H •swvao— -auujEJBd sn[d 'jna uaq* s3i«» jo )q3ia^l -g ! 1 S 1 S s •swvao — -JOD uaq* s3i*j jo jq3iaA -\ s 1 § m i 1 1 •SOIAU.

"In observing trees in continuous severe winter weather, ray attention has often been called to the fact that the twigs seem somewhat duller and more somber than usual, and in some cases tend to shrivel up and have the appearance of drying out. When a warm spell comes, this condition changes, and the twigs become brighter and seem to freshen up, and sometimes I imagine that they become more plump. The freshening -up feature is especially noticeable on large clumps or groves of willow; the twigs usually take on a much brighter color during warm spells in winter than during the continued freezing weather. During thawing weather, the equilibrium is main- tained between the moisture or sap in the tree top and that taken in by the roots, and as fast as mois- ture evaporates from the tree top, sap flows up from the roots and the equilibrium is re-established. In freezing weather, the moisture, even though frozen, is probably evaporating from the tree tops ; and the sap, being frozen, does not flow up from the roots and replace the evaporated moisture. Thus the equilibrium between the tree tops and roots is unbalanced, and it is at this time that the twigs become shriveled by reason of moisture being lost and not replaced. "In support of these statements, I made the fol- lowing investigation: After several days of con- tinuous freezing weather, and at a time when I expected a thaw, I cut twigs of a variety of trees and estimated the percentage of moisture contained in them. Again, just as soon as a thaw came, I cut Amount of Moisture Lost in Winter. 17 twigs from the same trees and from the same parts of the trees, and estimated the percentage of moisture again, the object being to determine if the twigs contained less moisture after several days of con- tinued freezing than they did a short time later, dur- ing a thaw. The last two columns of figures in the table (pages 14 and 15) are upon this subject. The average water content of those twigs cut dur- ing a freeze was 47.27 per cent, while that of those cut later, during a thaw, was 48.40 per cent, being an increase of 1.13 per cent, even though the trees had been constantly losing moisture by evaporation. Therefore I conclude that during every thaw in winter, the tree top fills with sap, and then if a sudden severe freeze comes, we are likely to have injured trees, due, no doubt, to the sudden freezing of the sap, and to the loss of moisture when none (ian be supplied. "It will be interesting to calculate what weight of moisture a tree may lose in winter. A certain soft maple, standing 30 to 35 feet high, with a trunk of 15 to 18 inches in diameter near the ground, ex- poses from 750 to 800 square feet of surface, and loses daily by evaporation from 170 to 180 grams of moisture. A given elm tree, 12 to 15 inches in diameter at the base, possesses some 300 to 400 square feet of surface, and loses daily from 70 to 100 grams of moisture. An apple tree 30 years old, with a trunk 15 inches in diameter, with a dense, bushy top, possesses approximately from 800 to 1,000 square feet of surface, and loses daily from 275 to 18 The Principles of Fruit-growing. 350 grams of moisture." These calculations, there- fore, may explain some of the injuries which follow very dry winters. Since evaporation takes place through the bark of winter twigs, it is reasonable to suppose that the tenderness of some trees in dry winter climates (as in our plains regions) may be due to such an ana- tomical structure of the bark as does not resist evap- oration, and that, on the other hand, hardiness may sometimes be a matter of thickness or denseness of bark. Studies in this direction have been made at Cornell, and they indicate that this supposition may be well founded in certain cases, but the investi- gations are not yet sufficiently extended to allow of any definite statements. The soil determinant. — There are special adaptations of fruits to soils. Pomologists are well aware of this fact as a general truth, but very little close attention has been given, in this country, to the minor applications of it. To be explicit, it is well understood that pears flourish best on clay soils and peaches best on sandy soils, but there are, no doubt, distinct preferences amongst the varieties of pears and peaches themselves. It is possible, in fact, that each distinct family or type of varieties of any species has preferences of land and location, and it will be the business of coming generations to de- termine what these peculiarities are. With the in- creasing refinements and competitions of the future, the special and local problems must receive more and more attention. If these positions are well taken, it Adaptation to Soils. 19 must follow that the promiscuous and wholesale dis- semination of a few varieties over the country must eventually cease, and that local and special sorts must constantly tend to drive out the cosmopolitan and general varieties. In this country, it is only in the strawberry that the peculiarities of adaptation of varieties to soils have begun to be well under- stood ; and this is rather because the subject is forced upon the attention by the short generations and constantly shifting plantations of the plant than from any investigational motive. Many of our fruits are very cosmopolitan as to soils, although there are, probably, none of them which are indifferent to even comparatively minor variations in land. Of the temperate fruits, the apple undoubtedly has the most generalized adaptabilities to soils, and this is closely seconded by the domestic plum. Amongst semi-tropical fruits, the orange thrives upon a wide range of soils. The peach and grape are more exacting, and the same may be said of the pineapple amongst semi-tropical fruits. Now and then fruits are made to grow in soils which are uncongenial to them by working them upon adaptive stocks. Thus the plum may thrive in sandy regions when it is budded upon the peach, the pear is sometimes grown upon very light lands by working it upon the mountain ash, and the ma- haleb cherry is thought by most persons to be a better stock for strong soils than for light ones. We may look for the time when certain varieties of the same species may be selected as stocks for 20 The Principles of Fruit -growing. given soils. But all this forced adaptation to soils is a very special matter, and it only illustrates the more strongly the great importance of giving par- ticular attention to the general subject of the adap- tabilities of species, varieties, and even of strains, to variations in soils. The parasite determinant. — Inasmuch as many of the organisms which seriously interfere with fruit- growing are more or less restricted in their range, it would seem to follow that the zones of profit- able fruit -culture may be determined more or less by the parasite factor. A moment's reflection will show, however, that the geographical distribution of the parasite is determined primarily by climate and by the distribution of its host -plants; so that, on the one hand, the climatal limit of the cultivation of the fruit may be approximately the climatal dis- tribution of the pest, and, on the other hand, the parasite is local or cosmopolitan according as the fruit is either local or widely grown. Many of the common pests are restricted in range because they have not yet reached the full limit of their distribution. An excellent illustration of this fact occurs in the case of the codlin-moth. A generation ago, Michigan was represented to be the Eutopia of the apple -grower because of the absence of this pest, and in our own day similar recommen- dations have been made of Oregon and other far western states. To the naturalist, however, it was evident from the first that the insect was following closely behind the apple frontier, as a storm follows The Alarm of Insects and Fungi. 21 an area of high pressure. It is evident, too, that no amount of legislative enactment could have stayed the dispersion unless it should have forbidden the planting of apple trees. As a matter of practice, the energetic and intel- ligent fruit-grower will think last and least of the parasite factor when locating his plantation, for this factor is variable and migratory, and, moreover, there are means of keeping most fruit pests under control. Insects and fungi are apt to be bugbears— sometimes literal bugbears — to the fruit-grower; but, after all, they are rarely to be counted upon as per- manent factors, and they are the direct and perhaps the most efficient means of keeping the farmer in a state of mental alertness. There are a few cases, of course, to which these remarks will not well apply, but they are clearly exceptions. One of these is the dreaded nematode root -knot of the southern states, and one might seriously hesitate in planting peaches where the ground does not freeze deep enough to destroy the pest. The professional ex- perimenters can determine the course of the life- histories of the various pests, and can point out their most vulnerable points, and may even devise general means for their eradication; but the final application of this knowledge is a local problem, which each man must work out for himself. Laws are generally of little avail for the destruction of pests, except in those few cases in which disease is more or less permanent or perennial, and in which there is no practicable recourse but to destroy the 22 The Principles of Fruit-growing. plant or the part affected. Such troubles are peach yellows, and black -knot of the plum and cherry. A law cannot be enforced unless public sentiment is behind it, and when public sentiment is aroused the law is not needed. Yet a law is often useful for a time to awaken public sentiment and to call attention to the evil. The final recourse is always greater knowledge and enlightenment. There are also insurmountable difficulties in the enforcement of laws designed to control the spread of noxious insects and fungi, because it is practically impossible to detect the eggs of insects or spores of fungi upon a large number of plants, and because there are" so many natural and uncontrollable ways in which the parasites may spread. The original Maryland law, designed to prevent the introduction of fruit-tree diseases and pests, was a case in point. It required that "whenever any trees, plants or vines are shipped into this state from another state, every package thereof shall be plainly labeled on the out- side with the name of the consignor, and a certifi- cate showing that the contents had been inspected by a State or Government officer, and that the trees, plants or vines therein contained are free from all San Jose scale, yellows, rosette and other injurious insect or disease." It would be impossible for any botanist to certify that a dormant tree were free of all disease ; and even in the matter of San Jose scale, an entomologist could not give a clean bill of health without giving more time to the examina- tion of a tree than it is worth, In the operating of Laws and Pests. 23 this law, trees were allowed to pass if an officer certi- fied that he had examined them and had found no evidence of disease thereon, which is a very different matter from asserting that they are free from dis- ease, and which is a virtual acknowledgment that such provisions of laws really cannot be enforced. The best laws of this nature, and for the regulation of spraying and the like, are probably those which are not mandatory, but which provide a protection or a legal remedy in case any person considers him- self to be endangered or injured by the perverseness or the negligence of another ; and it is a question if the common law does not provide ample redress for such grievances. There are instances, too, in which it may be wise to make a general effort to stamp out a pest when it first obtains a foothold in America, but this is a very different matter from the endeavor to control the spread of insects and fungi between the different parts of the country. The fact is, that most insects and diseases are beyond the reach of legislative fiats, and it is time that the fact were fully learned. The demand for functionary proceedings against the bugs sometimes recalls the laborious efforts of the Middle Ages. "At one time," writes Fernald,* "a thoroughgoing procedure, accord- ing to all the rules of jurisprudence, occurred before the spiritual judge. The accused insects were sum- moned, and in case of non-appearance, which always occurred, unless the insects were moving to new feed- *C. H. Fernald, "The Evolution of Economic Entomology," Proc.

Entomologists, 1896. 24 The Principles of Fruit-growing. mg grounds and the court-house happened to be in their way, a proxy was appointed to represent the accused insects, who debated the whole subject with the accuser, after which judgment was rendered, invariably against the accused insects in the form of an excommunication, which was carried into effect only when the insects disappeared at the time of pupation." The suggestion which Washington is said to have made upon the constitution whilst that in- strument was under discussion, is not inapplicable to the present subject. A clause having been pro- posed that the standing army should be limited to five thousand men, he suggested that another clause be inserted forbidding any foreign power to in- vade us with more than three thousand men! It is probably advisable to provide for inspection of plants at ports of entry, but too much should not be expected of such examinations. The exam- ination soon comes to be largely a perfunctory matter, and the most serious pests may easily slip through the hands of officers. It is probable that no law could be devised which could have kept the codlin-moth, Hessian -fly, gipsy -moth, and a score of other pests, out of the country, to say nothing of the fungous diseases, which are more difficult to detect. Then, again, one can never tell what insects are likely to become troublesome upon introduction into a new country. Many insects which are comparatively innoc- uous in their native country, and against which, there- fore, no suspicion exists, may become scourges in an- Natural Spread of Insects. 25 other country. A comparatively harmless insect in France becomes the dreaded horn -fly in America. Again, the demand for legislation usually arises be- cause of the incursion of some new intruder, but a pest is commonly worst when newly introduced, for, like a prairie fire, it finds its course unimpeded. After a time it reaches an approximate limit to its furious spread, parasites overtake it, and other pests oontest its feeding grounds. Nearly all insect pests lose much of their terrors after they have once run over the country. This is admirably illustrated in the potato-bug.* In other words, the first ap- pearance of a pest in formidable numbers is apt to result in a scare, to which, it is to be hoped, the San Jose scale, which is. now attracting so much atten- tion in the east, is no exception. The fact is, that insect and fungous pests are inevitable, and the farmer can have no peace of mind until he accepts the fact, and then resolutely prepares to meet them, both by strategy and direct battle. Yet, if now and then a serious pest can be kept out of the country, even for a few years, by means of in spectiou upon the frontiers, the effort may be emi- nently worth the while. * It may as well be said, once for all, that the writer uses the word bus for any hard-shelled insect. The entomologist uses it technically for a certain classificatory group of insects, and he generally insists that every- one else use it in the same way; but it should be remembered that the word was a common-language term long before the entomologist impressed it into special use. This common usage, therefore, has prior rights; and since it is impossible to make people use it in the entomological sense, it is plain that the entomologist must be prepared to accept any confusion which arises from his use of it. He can probably arrive at his purpose quicker and better by using purely technical terms. 26 The Principles of Fruit-growing. THE COURSE OF EVOLUTION OF A FRUIT REGION. Fruit-growing is usually a comparatively late de- velopment in any region. The epochs which precede the agricultural occupation of a country are com- monly about as follows: Discovery, exploration, hunt- ing, speculation, lumbering or mining. The real and permanent prosperity of a country begins when the agriculture has evolved so far as to be self-sustain- ing and to leave the soil in constantly better con- dition for the growing of plants. Lumbering and mining are simply means of utilizing a reserve which nature has laid by, and these industries are, therefore, self -limited, and are constantly moving on into uii- robbed territory. Agriculture, when at its best, re- mains forever in the same place, and gains in riches with the years; but in this country it has so far been mostly a species of mining for plant -food, and then a rushing on for virgin lands. The first effort in an agricultural region is gener- ally the growing of the staple crops, like the grains or bread-stuffs. This is both because the capabilities of the country are all unknown, and because such regions are far removed from the markets, and must, therefore, grow such commodities as can be stored or shipped long distances; and it may be said, also, that the growing of these crops in a new country demands comparatively little special skill. The second devel- opment is very often a stock-raising or grazing in- dustry. If the country possesses special adaptabilities for fruits, a man here and there will be found en- The Commercial Outlook. 27 and thereby escape, to a large extent, the effects of over-production. This c.an certainly be done. The very fact that there are years of over-production and under-production shows that fruit-growers have not yet mastered the con- ditions which control their plantations. In orchards, at least, there are more persons who discover their crops of fruit than there are who produce them. With the cheapening of the product, the demand will be increased. The United States now leads all countries in the extent, variety, excellence, and abundance of fruits, and our people are pronounced fruit -consumers : and this desire for fruit is very rapidly increasing. In particular fruits, as in grapes in the east, the price seems already to have fallen to the very lowest point of profitable production, and in these cases salvation seems to lie in the hunting out of special markets, in devising more secondary means of disposing of the product (as in 36 The Principles of Fruit-growing, manufactured goods), and especially in improving the quality of the product and increasing the attractive- ness of the packing. It is a common practice to estimate the amount of fruit which will be produced at any given time in the future by multiplying the number of acres of plantation by the yield of a normal acre of that kind of fruit. The fallacy in these calculations lies in the fact that very many of the orchards which are planted in hope and expectation yield only bugs and fungi. It is probably not too much to say that fully half of the fruit plantations which have been set in the past fail to produce any crop for the market. There are numbers of people who devote their entire energies to copying their neighbors ; but having no original grasp of the subject, they are likely to achieve only a haphazard success. CHAPTER II. THE LOCATION AND ITS CLIMATE. IT is apparent that any advice respecting the proper place for engaging in fruit-growing must be of the most general nature, since the species of fruits are so numerous, and the elements which enter into a choice of location and soil are so various and indefinable. Yet there are certain considerations which are approximately fundamental, and to which the reader may profitably give heed. These may be found to be suggestive in improving one's practice upon his established plantation, as well as useful in aiding him in the choice of location and land. THE PLACE. The choice of the place in which to grow fruit, leaving aside the element of soil,* is determined by the location and the site. The location is the po- sition of the place as fixed by the map or the sur- veyor. It is in such and such a township, and lies along such and such a highway. It is a matter of "The problems comprised in the selection of the proper soil must be de- termined for each particular fruit. They are, therefore, special questions, and must he treated in the books to be given to the different fruits, and not in a general work upon fruit-growing. (37) 38 The Principles of Fruit-growing. local geography ; it may lie in any one of a thou- sand places in the general fruit zones which were outlined in the last chapter. The site is the partic- ular or actual place, in the location or upon the farm, upon which the plantation is set. It comprises the aspect as to whether the exposure is towards the north or the south, and the consideration of the minor elevations and other topographical features of the place. To proceed, then, from the general to the speoinc, we may say that a certain fruit plantation is located at Willow Creek, in New York, and that it has a high site, with a sharp eastward exposure. In the choice of a location with reference to its geographical position, there are two chief elements to be considered, the choice with reference to market and that with reference to frosts ; and to these we may now proceed. Location with reference to market. — Time has over- come distance. Market facilities are, therefore, de- termined more by transportation facilities than by nearness to the market itself. To have the choice of two or more means of shipping — as by rail or water, or by more than one railroad — is a most desirable feature in the location of any fruit farm. This is not only because competitive rates 'may be secured, but also because more and various markets may be reached. The choicer the fruits and the greater the desire to reach personal markets, the more should the grower prize any means which shall enable him to reach a number of markets. Such a grower will desire to locate within easy reach of a The Market Factor. 39 number of cities or large towns. He will not care, perhaps, to grow what may be called the staple va- rieties, leaving that effort to those persons who are farther removed from points of consumption. It would seem to be unwise, therefore, for the fruit- grower who has access to several or many unlike markets to attempt to copy the methods of those in the west or south, who must grow largely of one thing and grow that in sufficient quantity to com- mand concessions from transporters and salesmen. Fruit-growing can never be reduced to a dead level of ideals and practice. In one place great speciali- zation may be most profitable, but in another place generalization — the extensive growing of general- purpose varieties — may be best. Location with reference to frosts.— In the last chapter, the general influence of cold and heat in determining the fruit zones was discussed. At that place, the subject was the average annual tempera- ture. But within these various zones there are end- less minor variations in physiographical features which have a direct influence in determining the areas of the incidental frosts of late spring and early fall. The reader must clearly distinguish between frosts and freezes. Frosts occur on still, clear nights, and are more or less local ; freezes are usually accom- paniments of storms, often of high winds, and are general or even continental in range, and their courses are not marked by the whiteness of frost. It was a freeze, and not a frost, which swept ever Florida in the winter of 1894-5, and over the north- 40 The Principles of Fmit -growing. eastern states in May, 1895;* and most of the serious disasters of untimely cold are of this kind. These freezes are mostly beyond the reach of man. He can only move beyond their limits. But injuri- ous frosts may not only be avoided, in many cases, by the selection of the location or even of the site, but they may sometimes be prevented upon the very '.light when they are expected. The chief local determinant of immunity from frost is proximity to bodies of water. These bodies act as equalizers of temperature. The water holds latent heat, and it does not respond quickly to the atmospheric fluctuations. It is, therefore, cooler in summer and warmer in winter than the adjacent land is. The larger and deeper the body of water, the greater is this equalizing effect upon the tem- perature of the shores. As between the two, great depth is more important than great expanse of sur- face. Lakes which are only a mile or two wide may exert a very profound influence over the adjacent * In order to show the natural history of one of these wide-area freezes, the following account is given (by E. T. Turner, Meteorologist of the Weather Bureau of the Department of Agriculture of the State of New York) concern- ing causes which led to the disastrous cold snap of May 13, 189.1, in New York state: " For about a week preceding the 12th, the temperature had been very high, from 80 to 85 degrees in the daytime and from 50 to 60 degrees at night. The temperature of the soil must, therefore, have been considerably higher than usual at that time of the year. The conditions which produced the freeze were very general rather than local. About the 9th, the pressure increased and the temperature fell over the western and central parts of the continent. Early on the llth a large low-pressure or storm area passed eastward over Canada, southerly winds flowing into it, giving the high temperature observed here at noon of the llth. But after the storm center passed further to the eastward we were subject to the cold westerly winds which flowed into the depression from the cold high-pressure area in the west, and which continued Influence of Bodies of Water. 41 land if they are very deep. This is admirably illus- trated in the slender lakes of central New York, about which the fruit-growing has disposed itself. The distance to which the ameliorating influence of the water may extend is determined very largely by the conformation of the shore lands. As a rule, there are distinct slopes towards the water, and it is rare that the effect of the water upon the temperature extends beyond the crest of the elevation. As a matter of fact, when the elevation is three hundred feet or more high, the region of immunity from frost ordinarily does not extend more than two -thirds of the distance to the summit. Along the central New York lakes, the area of the tender fruits, like grapes, does not reach more than half a mile, and at the utmost a mile, from the water. The famous Chau- tauqua grape -belt is confined to a strip about two to three miles wide lying upon Lake Erie, and reach- ing an elevation at its landward margin of less than also during the 13th, as the storm center lingered over the northeastern coast. The fall of temperature at this Station from noon of the llth to the 12th was 40 degrees, and by the 13th, 50 degrees. "This cold wave appears to have differed from ordinary frosts in the follow- ing particulars : Frosts commonly occur on clear, calm nights, when the cold air sinks to the valley bottoms ; but in this case the weather was cloudy or partly cloudy, and strong westerly winds prevailed. The valleys, being pro- tected from the wind, lost less of the soil warmth stored up during the pre- ceding week than the higher and more exposed localities, which suffered most. The temperature fell to 32 degrees or below over northern and central New York generally on the llth, 12th and 13th, and probably we were saved from disastrous frost in the valleys and sheltered localities only by the warmth of the soil. "I may add that the high-pressure area in the central states brought severe killing frosts near Lake Michigan and the central valleys on the 9th and 10th. With us there was the added feature of the high winds, due to the storm area as described. " 42 The Principles of Fruit-growing. two hundred feet.* Along the eastern shore of Lake Michigan, the peach area extends all the way from one or two miles to fifteen or twenty, depending upon the conformation of the surface. Along the lower Hudson River the area of the tender fruits does not depart, as a rule, more than a mile from the stream. In very gradual slopes, the ameliorating in- fluence of the water usuallj- extends farther, but it is apt to be less marked than upon the lower parts of abrupt slopes. In all these cases, the limit of the boundary of the area is determined by two factors, — the distance from the water, and the elevation above it. Tarr, after studying the local geography of the Chautauqua grape country, makes the following ob- servations upon the ameliorating influence of Lake Erie, and the remarks will apply to most other bodies of water: "The lake is a great modifier of climate. In the spring, by reason of the low temperature of its waters, it holds back the vege- tation, and this tends to keep it behind the ordinary frosts. Its very presence checks frosts by moderating the temperature of the neighboring air. In the summer, the water tends to cool the air of the day and to keep the nocturnal temperature fairly high. During the fall, the water has been warmed by the summer sun, and the influence of this warm body of water lengthens the growing season and tends to keep off the early autumn frosts. There are many other influences, but nothing of importance can be *For a detailed account of the physiography of this region, see R. S. Tarr, Pull. 109, Cornell Exp. Stn, Retardation of Bloom. 43 stated, excepting on the basis of a careful study extending over several years. The lake breeze of the day must moderate the daytime temperature; and the land breeze of the night may, in some cases, so keep the air in motion as to prevent frosts. That there is a marked influence upon cli- mate as a result of the peculiar conditions of topography and neighborhood of water, is evident at the very first. Sketeh maps show that the mean annual rainfall is greater on the escarpment than on the lake plain, and that the mean annual tempera- ture of the hills is lower than that near the lake." The particular influence which the water exerts over frost injury in spring is often due more to the retardation of the period of bloom than to the actual prevention of frost, although its influence in the latter direction is important. The lands adjacent to the water ordinarily warm up later in spring, and the trees are not likely, therefore, to swell their buds until danger of serious frosts is past. The amount of this retardation of bloom is often as great as ten to twenty days within a stretch of fifteen or twenty miles from a large body of water. It is well known that the danger from frosts is greatest in mild climates, in which "warm spells" are likely to occur in late winter or early spring. In the central and southern states, this frost injury following a period of warm weather is commoner than true winter -killing, whilst in the northernmost states and Canada serious injury to the trees from late spring frosts is comparatively infrequent. In the northern 44 The Principles of Fruit-growing. states, also, the plant goes into the winter in a perfectly dormant and ripened condition, and is thereby able to withstand great cold. It has been said that injury from cold is more frequent in the Gulf states than in New York. The elevation of any place also stands in close relation to the frostiness of it. Perfectly flat lands are nearly always frosty, because there is no atmos- pheric drainage, a subject to which we shall soon recur. On the other hand, very high lands are also frosty, because the air is drier and rarer, and there- fore allows of rapid radiation of heat from the land; and they are exposed to cold, unbroken winds. The local altitude to which the fruit lands may be carried can be determined only by actual experiment; but in the north the best elevations for the ten- der fruits are usually between 100 and 300 feet above the local rivers or lakes. Whilst it is extremely important that the loca- tion for the growing of tender or early -blooming fruit should be selected with reference to its im- munity from disastrous winter temperatures and un- timely frosts, it should also be said that climate is often held responsible for failures which are charge- able to ignorance or neglect. This is particularly well illustrated in the perishing peach -growing of some parts of the north. It is a common complaint that peaches cannot be grown so easily as formerly. The writer has investigated this matter upon the eastern shore of Cayuga Lake, in central New York-* *Bull. 74, Cornell Exp. St». Decline of Peach -growing. 45 a region which may be considered to be typical of the complaint that peaches are now particularly diffi- cult to raise. "There are many theories to account for this failure. Oftenest, perhaps, it is attributed to change of climate, but we have no proof that any considerable climatic change has occurred, while it seems to be true that the northern peach frontier is holding its own, or is even advancing. In New York the failure is often attributed to yellows, that disease which seems to exist as a vague and indefinable alarm in the minds of the general agricultural popu- lation. Yellows and increasingly rigorous climate are said to have wiped out the peach growing of the Cayuga belt. Twenty years ago a million peach trees, it is said, could be seen upon the eastern shore from one point upon the west side, but now there are only a few scattered orchards. Here, then, may be found the secret of this strange falling off of the peach trees in all parts of the country in these recent years. "Slanting towards the lake and pouring into it their drainage of water and cold air, laterally drained by deep ravines and protected from sweeping winds by lines of wood, these Cayuga lands seem to be ad- mirably adapted to the peach. But the region had never been a peach belt, in the sense in which that term will apply to the best part of the Niagara dis- trict, or to the Lake Michigan belt, or the areas in more southern states. In other words, peaches had never been a leading industry there, but the orchards had been planted here and there near the lake as a 46 The Principles of Fruit -(/rowing. very minor appendage to the general farming. For a generation or two of trees the insect pests were not common. There were no good markets, and the fruit sold as low as twenty -five cents a bushel from the wagon -box. In fact, it was grown more for the home supply than with an idea of shipping it to market. Under such conditions, it did not matter if half the crop was wormy, or if many trees failed and died each year. Such facts often passed almost un- noticed. The trees bore well, to be sure, but the crop was not measured up in baskets and accounted for in dollars and cents, and under such conditions only the most productive trees left their impress upon the memory. The soils had not undergone such a long system of robbery then as now. When the old orchards wore out, there was no particular incentive to plant more, for there was little money in them. Often the young and energetic men had gone west, there to repeat the history, perhaps, and the old people did not care to set orchards. And upon this contracting area, all the borers and other pests which had been bred in the many old orchards now concen- trated their energies, until they have left scarcely enough trees in some localities upon which to perpet- uate their kind. A new country or a new industry is generally free of serious attacks of those' insects which follow the crop in older communities. But the foes come in unnoticed and for a time spread unmo- lested, when finally, perhaps almost suddenly, their number becomes so great that they threaten destruc- tion, and the farmer looks on in amazement. Why Pmcl Orchards Fail. 47 "The cause of the failure of these early orchards, therefore, is the gradual dying out of the old system of agriculture and the coming in of special indus- tries. The methods followed with success a gene- ration and more ago are not profitable in the sharper competitions of the present time. At least, there is not the smallest evidence that there is any unusual or insurmountable difficulty in the way of peach growing in this once famous Oayuga region. The climate may be somewhat more bleak, but this difficulty may be lessened by the planting of shelter- belts; and there are enough protected places in which winds are not unusually severe. What yellows exists seems to have come in very recently. Good culti- vation and attention to borers, and the other diffi- culties to which peaches are everywhere subject, will enable the people in that region to grow better orchards than were grown there in former times. This statement is proved by the partial success which is even now attending those parts of the seven remaining orchards which are receiving as much as indifferent care." Winds and air-currents in relation to fruit-grow- ing.— It is necessary that more specific attention be given to the subject of winds and currents of air, an inquiry which is suggested by the preceding re- marks. There are the most various and contra- dictory opinions amongst fruit-growers as to the influence of winds upon fruit plantations. It is commonly admitted that high or rolling lands are best suited to most fruits, and many growers sup- 48 The Principles of Fruit-growing. pose that the reason of it is that winds there find free course. The truth is, however, that several features conspire to , render these lands congenial to fruits. Some of these characteristics are the follow- ing : Good atmospheric drainage ; the avoidance of still air in frosty weather ; good water drainage ; earliness or lateness, according as they are southward or northward exposures. High or strong winds are always to be avoided, if possible, for they blow off the fruit and injure the plants. As a rule, winds are beneficial to fruit planta- tions only when they bring warmer air, or when they keep the air in motion in frosty weather. If, therefore, high lands could be protected from winds without endangering atmospheric drainage or expos- ing the plantation to frost, much should be gained. In dry regions there is a special reason for de- siring to abate the winds, from the fact that they abstract so much moisture from soil and plants. Even a slight impediment in the path of the wind may give marked results in the conservation of moisture. Upon this point, King* writes as follows: "In arid or semi-arid countries, and in districts where the soil is light and leachy, but especially where there are large tracts of land whose inco- herent soils suffer from the drifting action of winds, it is important that the velocity of the winds near the ground should be reduced to the minimum. We have in Wisconsin extensive areas of light lands which are now being developed for purposes of *The Soil. 204. Land Covers to Conserve Moisture. 49 potato culture; but while these lands are giving fair yields of potatoes of good quality, they are in many places suffering great injury from the destructive effects of winds. On these lands, wherever broad, open fields lie unprotected by wind-breaks of any sort, the clearing west and northwest winds after storms often sweep entirely away crops of grain after they are 4 inches high, uncovering the roots by the removal of from 1 to 3 inches of the surface soil. It has been observed, however, that such slight bar- riers as fences and even fields of grass afford a marked protection against drifting for several hun- dred feet to the leeward of them. "In the case of groves, hedge -rows and fields of grass, their protection results partly through their tendency to render the air which passes across them cooler and more moist, and partly by diminishing the surface velocity of the wind. The writer has observed that when the rate of evaporation at 20, 40 and 60 feet to the leeward of a grove of black oak 15 to 20 feet high was 11.5 cc., 11.6 cc., and 11.9 cc., respectively, from a wet surface of 27 square inches, it was 14.5, 14.2 and 14.7 at 280, 300 and 320 feet distance, or 24 per cent greater at the three outer stations than at the nearer ones. So, too, a scanty hedge -row produced observed dif- ferences in the rate of evaporation, as follows, dur- ing an interval of one hour: "At 20 feet from the hedgerow the evaporation was 10.3 cc. " 150 " " " " " " " 12.5 " " 300 " " " " " " " 13.4 " 50 The Principles of Fruit-growing. "Here the drying effect of the wind at 300 feet was 30 per cent greater than at 20 feet, and 7 per cent greater than at 150 feet from the hedge. "When the air came across a clover field 780 feet wide, the observed rates of evaporation were: "At 20 feet from clover 9.3 cc. "150 " " " 12.1" "300 " " " 13. " or 40 per cent greater at 300 feet away than at 20 feet, and 7.4 per cent greater than at 150 feet. "The protective influence of grass lands and the disadvantage of very broad fields of these light soils was further shown by the increasingly poorer stand of young clover as the eastern margin of these fields was approached, even on fields where the drifting had been inappreciable. Below are given the number of clover plants per equal areas on three different farms, as the distance to the east- ward of grass fields increased: "No 1, at 50 feet, 574 plants ; at 200 feet, 390 plants ; at 400 feet, 231 plants. "No 2, at 100 feet, 249 plants ; at 200 feet, 277 plants ; at 400 feet, 193 plants ; at 600 feet, 189 plants ; at 800 feet, 138 plants ; at 1,000 feet, 48 plants. "No. 3, at 50 feet, 1,130 plants ; at 400 feet, 600 plants; at 700 feet, 543 plants. "In these cases the difference in stand appears to have resulted from an increasing drying action of the wind. On the majority of fields the de- structive effects of the winds were very evident to Uses of Low Wind-breaks. 51 the eye, and augmented as the distance from the wind-breaks increased. "It appears from these observations, and from the protection against drifting which is afforded by grass fields, hedge -rows and groves, that a system of ro- tation should be followed on such lands which avoids broad, continuous fields. The fields should be laid out in narrow lands, and alternate ones kept in clover and grass. Wind-breaks of suitable trees must also have a beneficial effect when maintained in narrow belts along line fences and railroads, and, perhaps, wagon roads, in places." Budd writes* as follows respecting the low wind- breaks of Manitoba: "Professor N. E. Hansen and others recently made a trip to Indian Head and Brandon. He was surprised to find miles of low wind-break not over five or six feet in height to stop the sweep of the wind on the surface of the earth. These low hedges are made by planting the shrubby artemisia. This grows readily from cuttings stuck in early spring, and soon attains its final height. It is really proving a blessing in that land of winds, where even the wheat is blown out of the ground if the wind is permitted to hug the earth's surface. We found this a common shrub on the steppes of central Russia, and introduced it as an ornamental plant. The thought did not occur that it would become the most popular wind-break of the wheat districts of Manitoba and Northwest Territory." Atmospheric drainage. — The air is rarely, if ever, » Rural Life, 189«. 52 The Principles of Fruit-growing. perfectly still. This is well illustrated in the vagaries of light frosts, which touch here and there where the air is the stillest or the radiation most rapid. This is particularly true in the growing months, when the earth becomes very warm during the day and loses the heat rapidly at nightfall, and when, also, the sky is less overcast by clouds than it is in the win- ter months. After studying the disastrous frosts of May, 1895, in the Chautauqua vineyard district, Tarr wrote* as follows : " The behavior of this frost was altogether remarkable, leaving some districts or vineyards almost unharmed, and nearly ruining the crop in others, while even in the same vineyard these extremes were sometimes noticed. This was probably chiefly due to eddies of the air, for even though air is almost quiet, it is still in uneven motion. One may see this illustrated on a calm day by noticing the movements of a column of smoke. The air, be- ing invisible, does not reveal these movements, and we become aware of them only when the conditions are exceptional, as when a frost is dealing out de- struction to vegetation. The condition of the ground also affects the frost, and the question whether it is dry or moist, freshly plowed or turf covered, whether there are trees or pastures or plowed ground in the neighborhood, all have their influence ; but this sub- ject has never been properly studied, and it is not possible to state just how these differences affect frost action." Much of this unrecognizable movement of the air *Bull. 109, Cornell Exp. Sta.. 121. Air Drainage on a Hillside. 53 is due to the draining off or settling away of the cold air, which is densest, and therefore heaviest. It pours down the valleys of hilly and mountainous countries, and as its vapor condenses it gives rise to the valley fogs and clouds. It lies in the low places upon the farm, and there may cause frost. A person riding across an undulating country upon a still sum- mer night can scarcely fail to notice the chillier air of the depressions. This escape of the cold air is the secret of much of the success of fruit-growing on rolling and sloping land; and this fact explains Fig. 1. The frosty belt below a wood upon a hillside. the importance of giving great attention to the selec- tion of the site and aspect when setting a planta- tion of the tenderer fruits. Features of such little apparent importance as not to appeal to the fruit-grower often exert great influence upon the quiet movements of air. A fre- quent case is this : A strawberry field is upon a gentle slope, and on the upper side is a wood. In time of frost, the only injury occurs in a belt two or three rods wide just against the wood, in the very place where the greatest immunity was ex- pected. This is because the slight bodily movement of the air down the hillside and over the forest 54 The Principles of Fruit-growing. strikes obliquely downward from the edge of the wood -top, and leaves a narrrow belt of dead air against the timber (as at A in Fig. 1, page 53.) The atmospheric drainage is marked only in still air. Winds mix up the air, and bring it all to a comparatively uniform condition. The slightest ob- stacles may sufficiently retard the movement to leave their impress in the distribution of a light frost. A rail fence, a stone wall, a row of bushes, a slight elevation of land, the earth thrown out of a ditch, — all of these are obstacles to drainage of cold air when they extend across a slope. In some cases, there may be a difference of ten degrees in tempera- ture in as many feet of elevation . A dense row of trees standing diagonally across a slope may convey away the cold air which settles down against it, and thereby prevent injury to plants on the lower levels. It has been suggested that in certain hilly regions, levees a few feet high be built diagonally across the slopes, with ditches or moats above them to hold water, the evaporation of which would tend to raise the dew-point. The range of elevation through which atmos- pheric drainage acts beneficially to the f ruit - grower is limited. A fall of a few feet in a plantation is often sufficient for the very best protection from light frosts ; and a fall of one or two hundred feet may be regarded as the general maximum through- out which the benefit may be observed, for very high elevations are, as we have seen, bleaker and colder in sum -temperature than comparatively low Temperatures on Hills. 55 § 5' ill I H § w II 2 ?a to h- » lo 3 SS tO 05 W I M I JO |» ^ - *. || I w o.

Statements of authors. — In connection with the foregoing reports, it will be well to review the statements of various writers respecting the use of wind-breaks: It [the fruit garden] should be screened on the north and the east, either by high walls and fences, or, what is far better, either by hills or a deep and dense border of evergreen or other forest trees, intermixed with fruit trees and shrubs of ornament. — Ken- rick, New American Orchardist, IX. (1832]. As our native forests become cleared away the climate is changed and becomes more harsh ; hence it is found desirable to construct some kind of protection from the point of most destructive harsh winds and storms. Belts of trees, either ever- green or deciduous, or both mixed, and surrounding or placed so as to screen from the northeast, north and northwest, are con- sidered highly advantageous. — Downing, Fruits and Fruit Trees of America, 54. The atmospheric changes and conditions we cannot control, and we can modify them only in a very limited degree, by hedges, by timber belts, and by evergreen screens, the value of which begins to be appreciated. — Warder, American Pomology, W7. 72 The Principles of Fruit-growing. In localities exposed to the sweep of winter winds, belts of evergreen or deciduous trees will be found of great service. In all instances where the side of an orchard exposed to the pre- vailing winds is less successful and productive than the opposite side, proof is afforded that shelter would be beneficial ; belts, especially if of deciduous trees, standing too near fruit trees, have, however, rather injured than benefited them. The orchard should be beyond the reach of their shade and roots, and be well ex- posed to sun and air. — Thomas, Fruit Culturist, new ed., 48. If possible, a situation should be chosen where some natural obstacle, as a hill, or a belt of woods, would break the force and influence of these destructive winds. Where no such ob- stacle naturally exists, a belt or border of rapidly growing trees * should be planted simultaneously with the planting of the orchard. ' Instances occur every year in our own section where sheltered orchards bear full crops, whilst those fully exposed to the winds fail entirely. — Barry, Fruit Gar- den, new ed., 176. Although having an orchard closely pent up by trees, etc., is injurious, nevertheless a screen of forest trees, at such distance from the fruit trees as that the latter will not be shaded by them, is of very great service in protecting the trees in spring from severe cold winds. — Bridgeman, Gardener's Assistant, by Todd, II., 39. A few orchards, in specially bleak situations, need protection from winter winds, but all orchards need wind-breaks toward picking time. The damage done in exposed orchards by the blowing off of fruit before it is reached by the pickers may amount to 50 per cent of the entire value of the crop, or even more. Belts of natural timber furnish most protection ; but they are apt to be the breeding grounds of noxious insects. A thick row of arbor vita?' (white cedar), like that shown in Fig. 2, is easily grown, and furnishes ample protection. This occupies some laud, however, and such dense belts of evergreens inter- fere seriously with atmospheric drainage (the rapid evening flow of cold air off the land to lower ground) . This is a most impor- Opinions of Wind-breaks. 73 tant consideration. Very satisfactory results have been secured in young orchards by planting between tree rows, and in encircling belts, with tall growing, western dent corn. It is practicable in some cases to plant Northern Spy on the more exposed sides of the orchard. This variety makes large trees, which protect the remainder of the planting, while the fruit holds on much better in arbor vitas wind-break. (Adapted from Waugh, Bulletin 55, Vermont Exp.

As the young wood and fruit buds [of the peach] often suffer from the pierc-ing blasts of winter, a spot that is sheltered from these is much to be desired. And, as they usually corne from the north and northwest, a site on the south or southeast of a wood or hill is, other things being equal, greatly to be preferred. —Fulton, Peach Culture, 68.

It is within the power of man greatly to modify the character of a situation by the judicious planting of belts of evergreens, by a wise addition of elements and a proper culture of the soil, and by encouraging the shade of the vineyard itself wherever circumstances indicates its necessity. — Strong, Culture of the Grape, 101. •'• . In general, it will be found necessary to secure protection on the west, north and northeast. * * * * No defense is better than a good belt of Norway spruce, and if they form a crescent in which the vineyard is embowered, but little danger need be apprehended from violent winds. — Phin, Open Air Grape Cul- ture, 40.

If trees are to be used, evergreens are best. — Ful- ler, Grape Culturist, 89. The location [for the vineyard] should be sheltered from the cold winds from the north and northwest. — Husmann, Culture of the Native Grape, 43. An artificial wind-break of this kind ["in the shape of an L, sometimes a perfect square," generally of cottonwoods, of the style prevalent in the west] is an excellent thing for the build- ings, and it should embrace several acres, but for protection to the orchard it is worse than useless. In a quiet, warm day in late winter these groves reflect the sun's rays, and, if continued for some days, will either start too early a growth, which is soon to freeze up again, or the freezing and thawing of the bark kills it in patches, and we have the next summer the evidence in the sloughing off of the bark on the sunny side, followed by decayed wood and a consequent swarm of borers, which take possession, Opinions of Wind-breaks 75 and death soon follows. It is generally conceded now by prac- tical orchardists that these wind-breaks are detrimental to the fruit trees, but we are frequently asked what we are to do to prevent the fruit from blowing off. We answer by asking what prevents this in an orchard of several hundred acres in extent?* Adam says that the best wind-break is "another row of trees." If it is determined to have this wind-break, why not make it of the Haas apple? — C. W. Gurney, Northwestern Pomology (Concord, Nebraska), 59. A free circulation of air is very desirable in an orchard, and full exposure is better than shutting in too closely, yet in a full exposure is not found the best condition for a successful orchard. It should be surrounded with wind-breaks on the ex- posed sides, sufficient to somewhat break the force of the wind, but not heavy enough to prevent a good circulation of air through the orchard at any time. It is much more important to have a wind-break on the south and west sides of an orchard than on the north or east, for it is from the former directions that come the most injurious winds. — Samuel B. Green, Amateur Fruit-grow- ing (Minneapolis), 74. Fig. 3. Protection of an orange grove from the morning sun. Though the climate of California renders unnecessary the pro- tection against rigorous weather which fruit-growers in some other parts of the world have to provide, there is often advantage in securing shelter from winds and protection from late frosts. *The outside rows act as wind-breaks. The larger the orchard, the less is the injury to the interior parts of it by wind. An orchard may be very completely protected by another one standing to the windward.— L. H. B. 76 The Principles of Fruit -growing. * It has already been remarked that on the immediate coast the successful growth of fruit will sometimes be wholly dependent upon proper shelter from prevailing winds, and in regions farther from the ocean the topography may induce strong currants of air, which will ill affect trees and vines. In all such places the fruit-grower should plant wind-breaks, and will find himself well repaid for the ground they occupy, by the success- ful production on the protected area. In the interior valleys there is also need of shelter from occasional high winds, which may visit the orchards either in summer or winter, and prove very destructive both to trees and fruit. — Wickson, California Fruits, 557. At Rivers [California] our orange groves are subject from Oc- tober to March to so-called "northers," a wind blowing from due north, and usually for three days and nights continuously. When orchards are not protected from these winds, the injury some seasons amounts to fully 75 per cent of the whole crop. Have also found that when the shelter belt was planted on all sides, and that on the east side was tall enough to shelter the orchard from the first rays of the morning sun, the injury from frost was only perceptible in the branches first exposed, while in orchards without the shelter on the east side, the damage was quite marked throughout the orchard. The diagram (Fig. 3, page 75) illustrates my meaning and experience. The top of the tree at the right was nipped by frost, whilst those at the left escaped. The Eu- calyptus globulus (Blue gum), Schinus molle (so-called Pepper- tree ) , and the Monterey cypress are all used for shelter belts ; the last named is the best.*— H. J. Budisill, in American Garden, XI., 563. Do not locate where your orchard will be exposed to severe winds. Quite a large proportion of fruit is lost every year by being whipped against thorns and branches, and the trees them- selves are sometimes half stripped of leaves.

A place free from strong winds is best, but some that are subject to them are otherwise exceedingly desirable. Some windy places have been proved to be the best in other respects for orange culture. If orchards be planted in places subject to wind, wind-breaks should be planted at once. — Garey, Orange Culture in California, IS. The frequent discussion of the subject [advantages of partial forest shelter] * among orange -growers, its impor- tance to all, and especially its importance to many portions of the state [Florida] where success must ever depend upon either forest or some artificial protection, demands careful attention. Many persons have heretofore considered it unnecessary, and the idea even absurd. But years of experience and observation, and especially the experience of the winter of 1876-7, have made many converts. — Moore, Treatise and Hand-book of Orange Cul- ture, 3d ed., 54. Forests and fruit-growing. — One of the reasons why fruit-growing is attended with increasing diffi- culties is because the forests have been destroyed, causing the country to become drier and hotter in summer and bleaker in winter. Forest, then, aids the fruit-grower in two important respects: 1. It prevents the disastrous effects of sweeping winds. 2. It conserves and regulates atmospheric moisture. It is very doubtful if the extremes of tempera- ture 01 fluctuations in annual means are more in- tense in recent years from the effects of forest re- moval. It may not even be true that there are more high winds now than formerly, but it is true that winds sweep over the farm with greater force. 78 The Principles of Fruit-growing. Winds sweep the surface and bear away the mois- ture of the soil at the same time that they come in contact with the trees and bushes themselves, and take away their moisture. The chief effect of the forest is to check the force of winds in pre- scribed areas. It has a local influence. Aside from all this, if forests were retained about the sources of creeks and upon springy hillsides, a more con- tinuous supply of water might be obtained for irri- gation, stock, spraying and domestic uses. It is worth saying, too, that a country which is dotted here and there with forest areas is a much more attractive one, to every person who loves variety of landscape and nature, than one which has been re- duced to a dead sameness by the removal of all timber. Whilst there are thus many advantages to fruit- growing of small forest preserves, there are also disadvantages. In certain cases they may become the harbors and rallying places of serious insect or fungous invasions. This difficulty may be largely avoided by cutting out those trees and bushes which breed the fruit-grower's enemies. The wild cherries are much loved of the tent caterpillars, the elm of the canker-worm, and wild roses and their kin of the rose-chafer. The cedar- apple fungus thrives upon the red cedar, and is thence transported to the quince or apple orchard, and a form of it affects the wild thorn trees. The red -rust flour- ishes upon the wild blackberries, dewberries and black raspberries, and the strawberry diseases breed influences of Wind-breaks. 79 upon the patches of wild berries. It is not often, however, that the forest areas become a very serious menace to fruit-growers. Review of the influences of wind-breaks upon fruit plantations. — The benefits derived from wind-breaks are numerous, most positive in character, and appear to possess sufficient importance to warrant the strongest recommendations of horticultural writers. Yet the injuries occasionally sustained in consequence of shelter belts may be serious, for it is a well attested fact that trees sometimes suffer from cold in the immediate vicinity of a dense wind-break when they escape injury in other places. This fact is easily explained, however. The influence of a wind-break upon the temperatures of an adjacent plantation is governed by its position with reference to prevailing or severe winds. Of itself, wind probably exerts little or no influence upon tempera- ture. It acquires the temperature of surfaces over which it passes. If these surfaces are colder than the given area, cold winds are the result, or if warmer, as a large body of water, the winds are warm. But wind often causes great injury to plants because of its acceleration of evaporation; and winds which are no colder than the given area, if com- paratively dry, may consequently do great damage to fruit plantations. This is particularly true at cer- tain times during the winter season. Land winds, being cold and dry, are therefore apt to be danger- ous, while winds which traverse large bodies of water, and are therefore comparatively warm and 80 The Principles of Fruit-growing. moist, are usually in themselves protectors of tender plants. The following table, giving the average temperature of different winds at New Haven, Con- necticut, as compared with the mean temperature of that place, shows that those winds which blow off the Sound are much warmer than the land winds:* Direction of wind. Average above the mean temp. Direction of wind. Average under the mean temp. Southwest + 4° Northeast - .6° Southwest + 4° Northeast - .6° South + 3.2° ;!

Similar ob- servations might be made concerning the Michigan stations. Temperatures of the coldest days would show much greater differences. It should be observed that the influence of a body of water is not governed by its proximity, but by elevation of the land and direction of winds. Grand Rapids, Michigan, although about twenty -five miles from Lake Michigan, is greatly influenced by it. It is evident that if a wind-break stops or deflects a warm wind, it may prove injurious. A still place in the lee of the wind-break may, therefore, be the coldest part of the plantation. So far as the writer is able to learn, this sort of injury from wind-breaks is confined to those regions which are directly influ- enced by bodies of water. The eastern shore of Lake Michigan has furnished many examples. Most growers G 82 The Principles of Fruit-growing. in that region demand a free circulation of air from the lakeward, while desiring protection from the east. (Cf. Mr. Cook's letter in Table IV., page 70.) This experience, however, does not argue that wind-breaks should be entirely abolished on the lakeward sides of plantations, but that such breaks should be thin enough to allow of the passage of wind, while break- ing its force. In such places, a wind-break should be simply a wind-break, not a wind -stop. The diagrams (Figs. 4 and 5) admirably illustrate Fig. 4. The deflection of winds over a lake bluff. these remarks. Fig. 4 is a diagram of a high bank on Lake Michigan. The strong winds from the west- ward strike the bank and are deflected upward, and strike the surface again at some distance from the cliff, leaving a comparatively still space at A. Decay- ing substances on the beach of the lake are often more obnoxious to those living half a mile or more from the lake than to those living near the bank. Fig. 5 is a diagram showing a similar deflection of wind and a comparatively still area (A) by a very dense wind-break. Deflection of Winds. 83 The advantages of wind-breaks in lessening wind falls, and in preventing the breaking of trees, dc not appear to be sufficiently understood. In sections which are influenced by large bodies of water, or when the fruits grown are sufficiently hardy to endure the most trying winds, these are the chief advantages of shelter belts, and are ample reasons for planting them. The greater facility with which labor can be performed in windy weather, under the protection of a wind-break, is worth consideration. The injuries sustained through the greater abun- Fig. 5. Deflection of winds by a dense shelter bel dance of insects immediately adjoining the wind- break are easily overcome with the modern spraying devices. There are many instances in which the wind-break lessens the vigor of one or two adjoining rows of fruit trees, but such injury appears to occur only where cultivation is poor, or where the wind- break has already obtained a good foot -hold when the fruit is set. The writer has examined a number of excellent plantations in which the rows next the wind-break are as vigorous and productive as any in the orchard. In fact, a number of good observers declare that best fruit and greatest productiveness 84 The Principles of Fruit-growing. occur next the wind-break. When the wind-break has been long established, however, it is difficult to make trees live alongside of it. The better plan is to plant the break with or only shortly before the orchard is planted. The following from T. G. Yeomans & Sons, Wai- worth, Wayne County, New York, who have had ex- tensive and pronounced experiences with wind-breaks, 'is a judicious statement of the advantages to be de- rived from shelter belts-. "We have been extensively engaged in fruit -culture for over forty years, and now have in bearing about one hundred and thirty acres of apple orchard, ten acres of dwarf pears, ten of orange quince, and small fruits. For many years we have experimented with wind-breaks, and now have many artificial shelter belts of various kinds and ages, the oldest having been planted nearly thirty- years. We consider wind-breaks to be of the great- est value to fruit culture, and we are confident that most fruit-growers do not realize their importance. They protect the trees and plants at all seasons, and prevent windfalls to a great extent. Orchards thus protected in this region are more productive, more uniform, and longer lived than others. They render labor among the trees and plants much easier on windy days, and enable men to work in very windy weather, when otherwise it would be impossible. We have always succeeded in raising good fruit close to the wind-break. * * * We consider land devoted to shelter belts as very profitable invest- ment, even to ordinary farm crops. We should not How to Make the Wind-breaTt. 8.~> attempt to grow dwarf pears, orange quinces or raspberries, without shelter of some sort." Position of the wind-break with reference to the fruit plantation. — It appears that a wind-break is desirable wherever the fruit plantation is exposed to strong winds. In order to prevent possible in- jury from too little circulation of air in certain localities, particular care should be exercised in the construction of the wind-break (cf. next section). The west, southwest, and north winds are the ones which need greatest attention in general. The pre- vailing winds are the ones which are chiefly to be avoided. This is particularly important in regions where these winds 'are normally strong, as on the ocean shore. In fact, it is generally impossible to grow successful orchards in full exposure to the ocean. How to make the wind-break. — From a general study of the subject, it appears that in interior lo- calities dense plantings are advisable, tight hedges being often recommended. This is because the winds, coming off the land, are likely to make the plantation colder. In localities influenced by bodies of water, however, it is evidently better practice to plant a belt simply for the purpose of breaking or checking the force of the warmer winds, still allow- ing them to pass in their course. Such a belt gives the desired shelter to trees when laden with fruit and ice, and may hold the snow, while danger from comparatively still air is averted. The damage from still air is usually observed in the lee of Construction of the Wind-break. 87 natural forests, and it is in such places that injury is reported by correspondents. The writer has found no indisputable evidence to show that such injury ever accompanies artificial wind-breaks; places where such injury was reported have been visited, but the loss of trees and fruit was plainly due to age of trees or other obvious reasons. Still, it is probable that a hedge -like wind-break may sometimes be the cause of mischief; and such should never be made in any locality until the problems of local atmos- pheric drainage have been well considered. The coarser evergreens, planted close together, are therefore advisable for interior places, while deciduous trees, or evergreens somewhat scattered, are often better for the lake regions. In these latter cases, however, the lay of the land is im- portant, for if atmospheric drainage is good there is less danger of injury from tight belts. Lower levels, upon which cold air settles, are therefore more in need of open belts than higher lands. For interior places, a strip of natural forest is the ideal wind-break. In artificial belts, the kind recommended by Messrs. Yeomans, and illustrated in Fig. 6, is undoubtedly one of the best. The illus- tration shows two rows of maples backing up a row of Norway spruce. "The maples then receive and break the force of the wind, and prevent the spruces from becoming ragged. We never shear the spruces." A Lombardy poplar wind-break alongside a peach orchard is shown in Fig. 7, on the following page. Fig. 7. A Lombardy poplar wind-break to protect a peach orchard, in south- western Michigan. Trees for Wind -breaks. 89 Correspondents in New York and Michigan ad- vise the following trees for shelter belts: Recommended by Norway spruce 25 persons. Austrian pine 5 " Scotch pine 3 " White pine 2 " Native deci'otis trees 2 " Lomlwrdy poplar.... 2 " European larch 1 " K«-oni mended l\v Hemlock spruce Arbor vit» Nut-bearing trees Hard maple Elm Basswood Willows... The gist of the whole matter is to select those kinds of trees which are most thrifty and healthy in the particular locality, and which are least in- fested by fungi and insects that are also common to fruit plants, and then to study the local condi- tions carefully to determine how dense or how open the shelter should be. For California, Wiekson* recommends species of eucalyptus, pepper or schinus, Monterey cypress, Monterey pine, osage orange, locust and maples. "Quite a number of the larger grow- ing deciduous fruit trees," he continues, "are used to some extent along the exterior lines of orchards for the protection of the iuclosure. The fig, the walnut, the chestnut, seedling almonds and apricots, are especially commended for such use." In Florida it is a common practice to leave strips of the original forest to serve as shelter belts. If this forest is hammock land, and there- fore well clothed underneath, the protection of a belt two to four rods wide will be most complete. 'California Frnits, 558.- 90 The Principles of Fruit-growing. The cabbage palmetto is often allowed to stand promiscuously through the orange plantation, partly to serve as a protection from winds, partly for shade and ornament, and partly to exert some sup- posed influence in correcting the acidity of the land. In exposed places, orange -groves are sometimes protected by very tall open fences. General summary upon wind-breaks. — 1. A wind- break may exert great influence upon a fruit planta- tion . 2. The benefits derived from wind-breaks are the following : Protection from cold ; lessening of evapo- ration from soil and plants; lessening of windfalls ; lessening of liability to mechanical injury of trees ; retention of snow and leaves ; facilitating of labor ; protection of blossoms from severe winds ; enabling trees to grow more erect ; lessening of injury from the drying up of small fruits ; retention of sand in certain localities ; hastening of maturity of fruits in some cases ; encouragement of birds ; ornamentation. 3. The injuries sustained from wind-breaks are as follows : Preventing the free circulation of warm winds, and consequent exposure to cold ; injuries from insects and fungous diseases ; injuries from the encroachment of the wind-break itself ; increased lia- bility to late spring frosts in rare cases. a. The injury from cold, still air is usually confined to those localities which are directly influenced by large bodies of water, and which are protected by forest belts. It can be avoided by planting thin belts. Summary upon Wind-breaks. 91 b. The injury from insects can be averted by spraying with arsenical poisons. c. The injury from the encroachment of the wind-break may be averted, in part at least, by good cultivation, and by planting the fruit si- multaneously with the belt. So far as practicable, the wind-break should be planted at a distance of six rods or more from the fruit plantation. 4. Wind-breaks are advantageous wherever fruit plantations are exposed to strong winds. 5. As a rule, in localities where atmospheric drainage will not be seriously checked, the wind- break should have a comparatively dense bottom, formed by undergrowth or low -branching trees. 6. The wind-break should never be dense enough to force the buds on fruit trees in those localities which are subject to late spring frosts, as it may sometimes do when it faces the south and acts like a southern exposure for the plantation. It is evi- dent, therefore, that spruces and other evergreens should be planted sparingly in such localities, and that deciduous trees which leaf out late in spring should be chosen for the wind-break. 7. In interior places, dense or broad belts, of two or more rows of trees, are desirable, while within the influence of large bodies of water narrow belts, comprising but a row or two, are usually preferable. 8. The best trees for wind-breaks in the north- eastern states are Norway spruce, and Austrian and Scotch pines, among the evergreens. Among decidu- ous trees, most of the rapid -growing native species 92 The Principles of Fruit-growing. are useful. A mixed plantation, with the hardiest and most vigorous deciduous trees on the windward, is probably the ideal artificial shelter belt.* PROTECTING PLANTATIONS PROM FROST. Having now considered the relations of location, site and wind-breaks to cold and frost, we may ad- dress ourselves to a discussion of the means by which injury from local frosts may be averted, in case they threaten to occur. These means are of two types, — those which attempt to enable the plant to escape injury from the frosts, and those which attempt to prevent the frost from occurring. Altogether there are six general means which have been proposed for protecting plants from frost: Mulching, covering the plants, adding the vapor of water to the atmosphere, making artificial clouds, causing currents of air, and heating the air.f Middling to enable plants to escape frost. % — It is a general opinion that a mulch or heavy cover placed upon the soil about plants when it is frozen will re- tard flowering and the maturing of fruit ; yet the practice appears to be often unsatisfactory, and there are reasons for supposing that the philosophy of the subject is not commonly understood. The subject is one of increasing importance, for it is essential that *Bnll. 48, Neb. Exp.

Efforts must also be made to reach the market when there is least competition from other sources, and, in the north, at least, this competition comes chiefly from early products produced in states to the southward. A rehearsal of experi- ments made to test the efficiency of mulching for these purposes will indicate the nature of the problem. The tests were made at Ithaca, New York. The ground froze deep in December, and the frost did not leave it until the mid- dle of March. Upon the 28th of February, 1893, the snow being well settled and a foot and more deep in the open fields, heavy mulches of coarse manure and litter from horse stables were placed about apples, almonds, buffalo berries, blackberries, rasp- berries, currants, gooseberries, grapes, June- berries, peaches and quinces ; and straw- berries were mulched later. Observations were also made upon roses which were mulched in the fall for winter protection. The apples and other tree -fruits com- Fig. 8.

Half of a large wagon load s'hoot*08* of mulch was placed about each tree, covering the snow deep for a distance of three feet or more in all directions. The small -fruits were mulched heavily to the middle of the rows, or three and a half to four feet in each direction. A heavy 04 The Principles of Fruit-growing. wagon load of mulch was sufficient to cover about ten feet of row. On the 29th of March, these mulches were examined, and, although the frost had left the fields fully ten days before, the earth under the cover was still solidly frozen and from six to eight inches of snow persisted. Here, then, was an excellent opportunity to study the effects of a cold soil upon the vegetation of plants. On the 13th of April, there was still frost and snow under the goose- berry mulches, and yet both mulched and unmulched plants seemed to be starting alike. It was appar- ent that the temperature of the soil exerted no influence upon the swelling of the buds, for the buds which projected above the mulch were as for- ward as those upon untreated plants, while the buds immediately under the mulch, upon the same twig, were wholly dormant. The illustration (Fig. 8, page 93) shows a gooseberry twig upon which this differ- ence is apparent. The twig was covered up to the point indicated by the mark (A). The protruding portion is seen to have pushed its buds forward, except the very tip, where the shoot was winter killed. Shoots of which the tips were caught under the mulch showed perfectly dormant buds at both ends, while the protruding middle portion was as forward as twigs upon unmulched plants. Moreover, the protruding portions of the mulched plants main- tained their forwardness, and produced leaves, flow- ers and fruit at the same time as the contiguous plants which were not treated. Crandall currants, Juneberries, roses, grapes, and all the tree fruits, The Stored Food. 95 behaved similarly throughout the season. The mulched blackberries, raspberries and Victoria cur- rants seemed to be a day or two behind the others in starting, but they very soon caught 'up, and there was no difference in season of bloom and maturity of fruit. With the strawberries the case was far different. General Putnam and Oregon Everbearing were mulched March 25, when the ground was completely t ha wed out. The mulch covered the plants and the entire space between the rows to the depth of three inches. On the 15th of May, this mulch was re- moved. At this time, the unmulched plants were in full leaf, and were nearly ready to bloom. The plants under the mulch were just starting into leaf, and the growth was weak and bleached. The plants were endeavoring to push themselves through the cover to the light and air. The mulch was forked off the plants, and they gradually assumed a normal color and habit, and bloomed June 1. The bloom was delayed from ten days to two weeks, according to the depth of the covering. The plants did not seem to recover entirely, however, and the fruitage was somewhat lighter than on the normal plants ; but it was delayed about a week. All this is what the botanist would have ex- pected. It is well known that plants store up starchy matters in their bulbs or branches, to be used in the growth of the adjacent parts in early spring. The earliest bloom of spring is supported by this store of nutriment, rather than by food 96 The Principles of Fruit-growing. freshly appropriated from the soil. This is well illustrated by placing well -matured twigs of apple or willow (or other early -flowering plants) in vases of water in winter, when the buds will burst and flowers will often appear. It was admirably enforced by a simple experiment which we made in connec- tion with the foregoing inquiry. On the 15th of February, a branch of a nectarine tree which stood alongside the horticultural laboratorj- was drawn into the office through a window. This office was maintained at the temperature of a living room. On the 6th of April the buds began to swell, and the young leaves had reached a length of three- fourths inch a week later. The leaves finally at- tained their full size upon this branch before the buds upon the remaining or out -door portion of the plant had begun to swell. This experiment is by no means a novel one, for essentially the same thing has been often accomplished with the vine and other plants; but it must impress upon the reader the fact that much of the bursting vegetation of springtime is supported by a local store of nutriment, and is more or less independent of root action. These various experiments and observations show that a mulch can retard flowers and fruit only when it covers the top of the plant as well as the soil. If the ground could be kept frozen for a sufficiently long period after vegetation begins, the plant would consume its supply of stored food, and might then be checked from inactivity of the root, but this would evidently be at the expense of in- Effects of Mulching. 97 jury to the plant ; but, in practice, it is fortunately impossible to hold the frost in the soil so long. It is evident, too, that the covering of strawberries and other low plants for the purpose of retarding fruit must be practiced with caution, for a mulch of sufficient depth to measurably delay vegetation is apt to bleach and injure the young growth, and to lessen the crop. Yet it can sometimes be used to good effect, and fruiting can be delayed a week, perhaps even more. Some skilful strawberry -grow- ers are able to delay fruiting upon small patches as much as two weeks by means of mulches. We may draw the following conclusions upon the effects of mulching to retard bloom : 1. The early bloom of fruit -plants depends very largely upon the appropriation of food stored in the twigs, and it is more or less independent of root action. This is proved both by direct experiment and by study of the physiology of plants. 2. It must follow, then, that the temperature of the twig or branch must be reduced if its vegeta- tion is to be much retarded ; or, in other words, the top of the plant, as well as the soil, must be mulched, and in practice this is possible only with strawberries and other very low plants, or those which are laid down during winter. 3 There is danger of injuring plants by heavy mulch which is allowed to remain late in spring. If it is desired to retard flowers or fruit by mulch- ing, the practice should not be violent, and the plants should be carefully watched. 98 The Principles of Fruit-growing. 4. Many strawberry -growers are able to delay the ripening of fruit by mulching from two days to two weeks ; but a week's delay is usually about the limit of profitable results. 5. Whilst mulching the ground may not retard the period of bloom, and thus enable the plant to escape frost, it is, nevertheless, often useful in pro- tection from frost because it holds moisture, and, therefore, tends to raise the dew-point, as explained farther on. Covering plants for protection .—The discussion of the mulching of strawberries in order to protect them from cold and from frost, as already described, really belongs here. It is, of course, well known that plants may be covered to protect them not only from the winter's cold, but from the incidental frosts of spring. It is not necessary to discuss the various means of covering them, but to enter into only sufficient detail to enable the reader to grasp the capabilities of the operation. Many low -growing plants can be covered with earth for protection. Thus it is a practice in some places to plow a furrow or two over the strawberry rows when a frost is anticipated, Fig trees, and other low or flexible -stemmed plants, are often planted on sloping land, so that they may be bent to the surface and covered when occasion requires. In parts of Russia, and other cold countries, the trees of orchard fruits are often pegged down in a similar manner. Blackberries and raspberries are extensively laid Laying Down UK 99 down in cold climates, and it may be well to relate the method here, for the benefit of those who occupy bleak locations. Late in fall, the bushes are tipped over and covered. Three men are generally employed to perform this labor. One man goes ahead with a long-handled, round-pointed shovel and digs the earth away six inches deep from under the roots. The second man has a six- KiK. !».

Heating the air. — It is sometimes possible to di- rectly heat the air by means of large fires, although such practice does not seem to have generally met with encouraging results. In the combined smoke and vapor smudges which have been commended by Hammon (page 112), the heat of the fire may add something to the efficiency of the protection. The strong currents of air which are set up by heavy fires seldom aid in the protection of the plantation. Yet there are cases in which hot fires have saved trees over considerable areas from heavy frosts and even from freezes. One of the best experiences in this direction is reported from Florida by Da vies.* In the freeze of February, 1895, he was able to raise the temperature in his grove from 18 degrees to 33 degrees by means of fires. "On the north and west sides of your grove have what are called conflagrations, big fires, that will send billows of heat rolling between and over your tree tops ; and all through your groves, at short distances, have small fires to help on the good result." Mr. Davies recommends that orange growers "get ready, and keep ready all the time, for the freeze. Once it has come, there will be no time for gathering materials for fire. Your fuel must be on hand, and plenty of it." It is then necessary to keep the fires burning vigor- ously until the cold spell has passed. H. R. Ste- *D. O. Davies, "Protecting. Orange Groves from Cold," Fla. State Hort. Soc. 1896, 28. Foretelling Frosts. 121 vens, 011 the same occasion, reports success in sav- ing orange trees from cold by burning rosin, secur- ing both heat and smoke. He makes cones six inches high and six wide of common hardware paper which lias received a coat of paint. These cones are filled with cheap rosin and set near the trees. A little of the rosin is pulverized on top, and it is then set on fire from a bit of oiled waste which is dropped on it. Six pounds of rosin burn about an hour. THE PREDICTION OF FROST. In considering the means of predicting frost, it is first of all important that the student should ob- tain a clear idea of the usual or average dates of the opening and closing of the seasons of his locality. Records made by himself upon his own farm from year to year are invaluable. He may derive very much help, also, from the records of meteorological bureaus. A general tabulation of spring and fall seasons (see pages 123 and 124) may be suggestive in this connection:* "The data for the accompanying tabulation of the killing frosts of the region east of the Rocky Mountains was compiled from the bulletins and an- nual reports of the United States Weather Bureau. The table is divided into dates for spring and fall, and these in turn into earliest, latest, and average *Made by Alexander D. MacGillivray, Assistant in Entomology, Cornell Uni- versity. 122 The Principles of Fruit-growing. dates. By 'earliest' is not meant the first frost in the spring, but the earliest date at which the season has opened, while when applied to the fall it is the first actual occurrence of a frost. By 'latest' is meant the last occurrence of a killing frost in the spring, and in the fall the latest date at which the season has closed. The average date is in most cases the mean of average dates given by the Weather Bureau. "The states have been grouped into three regions, the states of the coast plain, the states of the Ohio River basin and its adjuncts, arid the states of the Missouri River and its adjuncts. The first thought in separating the states into these regions was that they represented distinct faunal regions, and that they probably represented distinct climatal regions. This has been sustained in most part. The most marked cases are eastern New York, or the Hud- son Valley, and western New York, the former be- longing to the coast states and the latter to the Ohio valley states. There is a difference of eleven days in the spring on earliest dates, twelve days on latest, and two days on average ; Pennsylvania, which falls in the same category, in the spring, fifty-four days on earliest, eleven days on latest, and twenty days on average dates. In the other regions the difference is not so marked, and yet there is some difference in all cases. "This tabulation is of interest in showing the earliest and latest dates at which the seasons have opened, for some of the data is based on records Records of Frosts. 123 TABULATION OF SEASONAL CHANGES, WITH SPECIAL REFERENCE TO KILLING FROSTS.

"The effect of topography is shown well in the cases already cited, eastern and western New York and Pennsylvania. It is equally true of Virginia and West Virginia, and North Carolina and Ten- nessee. The effect of situation is shown markedly in the case of Maine, which is north of New Hampshire and Vermont, and yet earlier. Georgia's season opens twenty -one days later than South Car- olina's, and ten days later than Alabama's, while North Carolina is ten days later." The liability of any particular locality to injury from late spring or early fall frosts is capable of being expressed in charts or by other graphic means. Very good records of the habitual frosti- ness of any place could be made by an army of careful growers who had neither a barometer nor a thermometer. Let us suppose, for instance, that the peach - growers of a certain geographical area were to make observations for a number of years upon the relative synchronisms of late frosts and bloom- ing-time, a subject which is of the most vital im- portance to every grower of the tender fruits. The tabulation of these observations would enable us to construct two series of curves, which would indicate at a glance the comparative safety of an}- station for the cultivation of the given crop. We will suppose that observations have been taken for a number of years by various persons at seventeen 126 The Principles of Fruit-f/rowing. ! -: Frost and Blooming Time. 127 closely connected stations, represented by the letters in the margin of the plate (page 126). One curve represents the date of the last killing frost, and the other the date of the opening of the peach flowers. Wherever the frost line lies beyond the bloom line, as in the first five stations, peach-grow- ing is impossible. When it lies at the left, peach- growing is possible, and the industry is safe in proportion as the two lines diverge. At the stations I, K, and O peach - growing may be considered to be far beyond danger of late frosts. These tabula- tions would be valuable, of course, in proportion as they include a minute record of every farm in the given territory ; but even a somewhat superficial series of observations would possess great value if accurately made, as indicating the probable influence of local climate upon the given industry. If lines tend to converge, or if the frost line crosses beyond the bloom line, there is indication, at least, that safe peach lands are few in those localities. The information which these records ask could be well ascertained from observations upon a few peach trees here and there long before any general experi- ment of cultivation had been tried. This method of study is a part of the science of phenology, or that science which treats of the periodical phenomena of animals and plants, as the migrations and nesting of birds, awakening of the frogs, and the dates of blooming and leafing of plants. Such records are more accurate measures of seasonal climates than instrumental measurements 128 The Principles of Fruit-growing. are. Some day the country will have charts of iso- phenal lines as well as of its isotherms. Local studies of this type must eventually come to be an important province of meteorological bureaus. Every state must ultimately be completely charted not only in respect to liability to frosts, but to other incidents of local climate and weather. The most reliable prediction of frost is given by readings from the wet- and dry -bulb thermometer, which measures the moisture in the air. Kedzie gives the following description of this thermometer : * "The sling psychrometer is a formidable name, but a simple instrument. It consists essentially of two thermometers, the bulb of one being left naked and kept dry, the bulb of the other being covered with a thin layer of cloth which is kept wet ('wet -bulb') during the time of an observation. By placing these 'dry -bulb' and 'wet -bulb' thermometers side by side and comparing their readings, we may determine the amount of cold produced by evaporation, and thus measure the relative dryness of the air. If there is no evaporation the two thermometers will show the same temperature, but any evaporation will produce cold, and the more rapid the evaporation the greater the reduction of temperature. The drier the air the more rapid the evaporation, and the greater the cold caused by evaporation. The psychrometer, or the 'wet- ajid dry-bulb thermometer,' affords the means for .determining the amount of moisture in the air, *See also Horticulturist's Rule-Book, 4th ed., 222. Tlte Ming Psychrowieter. 129 and the temperature of complete saturation or dew- point, by measuring the reduction of temperature by evaporation . "A sling psychrometer can easily be made, as fol- lows : For the frame, take a board eighteen inches long, two inches wide, and one -half inch thick, with a hole bored in one end to hang the apparatus on a nail when not in use. Get two all -glass thermom- eters with cylindrical bulbs, and the degrees Fahren- heit engraved on the stem. Cover the bulb of one thermometer with a thin piece of cotton cloth, fastening it securely by a thread. When this cloth covering is wet with water and exposed to evapo- ration in the air, it constitutes the 'wet -bulb ther- mometer ' ; the other thermometer has no covering on its bulb, is not wet at any time, and constitutes the 'dry -bulb thermometer'. "Securely lash the thermometers on opposite edges of the narrow board, leaving the graduations on them plainly in sight, and the bulbs extending a short distance below the end of the board. To use the instrument, wet the cloth -covered bulb with water, leaving the other bulb dry, and then swing the apparatus freely through the air for three to five minutes, or until the wet -bulb thermometer ceases to fall in temperature, and then read the temperature of each thermometer. Unless the air is saturated with moisture the wet -bulb will always show a lower temperature than the dry -bulb. Sub- tract the degrees of wet -bulb from those of the dry -bulb, and the remainder will show the degrees j 130 The Principles of Fruit-growing. of cold produced by evaporation. Suppose the dry bulb marks 65° F., and the wet bulb 56°, then 65° - 56° = 9C or the cold produced by evapora- tion. This swinging and reading of the pyschrom- eter are done in the shade in the open air when the temperature of dew-point is sought ; it should be done rapidly and the ther- mometers read promptly The dry -bulb gives the temperature of the open air, and dew-point is de- termined by reference to tabulated figures." A com- mon form of psychrometer is shown in Fig. 11, but inasmuch as this has a cup of water connected with the wet -bulb, it is not so handy for whirling. Such an instrument may be fanned instead of whirled. Hammon gives the fol- lowing directions and fig- ures for determining the dew-point : " To obtain the dew-point from the wet -and dry -bulb hygrom- eter or psychrometer, moisten the muslin on the i'ig. 11.

Continue the ven- tilation until the wet -bulb thermometer ceases to fall, when the two thermometers should be read. Subtract the reading of the wet -bulb thermometer from that of the dry. Find this difference in the column at the left of the table. The dew-point will then be found at the intersection of the line opposite this difference and the column which is headed by the number nearest the air temperature (dry -bulb reading). Examples are given below: " Dry -bulb thermometer 55° Wet-bulb thermometer 44° Difference 11° Dew-point from table 30° " The dew-point is the temperature at which the deposition of dew be- gins. Frost is formed when the dew-point and freezing-point coincide (that is, at 32°). The nearer the dew-point approaches the freezing-point nt nightfall, the greater is the danger ot frost during the niglit. When the dew-point is 10° above freezing-point at nightfall (42°), there is little danger of frost; but when it is less than this, frost may be expected. w DEW -POINT TABLE.

THE TILLAGE OF FRUIT LANDS. THE study of the evolution of the ideas respect- ing the tillage of the soil opens one of the most interesting chapters in history. The subject is all the more suggestive because tillage is such a com- monplace and almost universal labor that no one thinks of it as having had a history. Yet the practice of the simple stirring of the soil has been slowly evolved, like all other methods and institutions, through a long period of time, and as the result of many forces which were unobserved or even unknown at the time. We think of tillage as a custom ; and if one considers the condition of farming at the present moment, he would seem to be warranted in such an association, for a custom is a habit which is not suggested by reason and inquiry. Per- haps the only reason which most persons could give for the tillage of the land is that they are obliged to do it. It would seem to be the simplest and dull- est thing to till the soil. It is simply the driving of the animal and the holding of the plow, or taking care that the harrow scarifies the entire surface ; or it may be only the stubborn wielding of the hoe or rake. This view of the matter is wholly correct (133) 134 The Principles of Fruit-growing. when one thinks of tillage only as labor. The work must be done because, somehow, plants thrive best when it is done ; but the sooner it is done and the less there is of it the easier, and what is the easier is the better. It was, no doubt, some such mind as this which dominated the rude farmers in the early history of the race Throughout all the years until now — and, unfortunately, too often even now — tillage has been a mere necessity forced upon the husbandman by a most ungenerous Nature. The first tillage probably arose from necessity of breaking the earth to get the seed into it ; and the second step was the dig- ging out of other plants which interfered with its growth. In many cases, still another hardship was imposed, for the earth must be disturbed to get the crop out of it. These three necessities served to keep the surface of tamed lands in a greater or less state of agitation until it finally came to be seen that there is something in the practice which causes plants to thrive wholly aside from the lessening of the con- flict with weeds. But it is only in the last century or two that there appears to have been any serious attempt to discover why this age -long practice of stirring the soil is such a decided benefit to plants. One reason why the art of tillage has made such slow progress is because it seems to be wholly con- trary to the operations of nature. In very recent years it has been vehemently proclaimed that the proper treatment of an orchard is to plant it thick and to allow the leaves and litter to cover the Forest and Orchard Unlike. 135 ground, wholly omitting the stirring of the soil, for this is the method of the forest ; and forest lands increase in fertility from year to year and the mois- ture is held in them as in a sponge. The reason- ing is plausible. There are two ways of testing it, — by experience and by reflection. It needs only to be suggested that the experiment has been tried, and is now trying, upon an extended scale, as a large part of the apple orchards of the country testify. The chief .beneficiaries of the experiment are the bugs, mice and fungi, all of which would vote the method a success. The reasons why the forest method is successful are because the trees stand so thickly that the earth is protected from the drying effect of sun and winds; the forest cover is so ex- tensive as to produce a climate of its own, all the product is returned to the soil, and there is no haste. In every one of these essentials the orchard is unlike the forest. Those writers who urge that the orchard be planted thick enough to imitate the forest condition, should also make it clear how the insects and fungi are to be kept at bay, or how acceptable fruit can be obtained upon trees which are unpruned and unthinned. The objects to be attained in the forest and in the orchard are wholly unlike. In one case it is the perpetuation of the species, and there results a severe conflict for exist- ence, in which more plants die than reach maturity; in the other it is the securing of an abnormal pro- duct of the plant,— a product which can be kept up to its abnormal or artificial development only by 136 The Principles of Fruit-growing. abnormal conditions,— and the struggle for existence is reduced to its lowest terms, for it is desired that not a single plant be lost. It is simply because it is impossible to imitate the forest conditions that the forest methods cannot be followed in fruit plantations. Now that we have come to understand why and how it is that the stirring of the soil makes plants thrive, the old-time drudgery of tillage becomes the most important, the most suggestive, and therefore the most difficult to properly understand and perform, of all purely farming operations. If we cannot have the protection of the forest cover and the forest mulch, we must make a mulch for the occasion ; and if we wait impatiently for results, we must un- lock the granaries of the soil more rapidly than nature does. We must till for tillage's sake, and not wait to be forced into the operation — as men have generally been — by the weeds ; yet, whilst we have outgrown the need of weeds, we should not despise them, but remember them kindly for the good which they have done the race. They have been an inexorable priesthood, holding us to duty whilst we did not know what duty was, and they still stand ready to extend their paternal offices. Coming, now, to the specific question of the till- age of fruit lands, one is struck with the fact that all kinds of fruits are commonly more productive than the apple ; and a moment's reflection brings to mind the fact that the apple alone is the fruit which is commonly raised in sod, and which every- Old and New Methods. 137 where receives the least attention. The presumption is at once raised, therefore, that this sod and neg- lect are in some vital way associated with the de- clining productiveness of apple trees. In order to put ourselves right upon the question, we must first of all ascertain, if we can, why the apple is of all fruits the most neglected. My older readers will recall the fact that until recent years the effort of the farmer has been di- rected to the growing of hay, grain and stock. Previous to this generation, the growing of fruit has been a matter of secondary or even incidental importance. A bit of rocky or waste land, or an odd corner about the buildings, was generally given over to the apple orchard, and if the trees received any attention whatever it was after all other de- mands of the farm had been satisfied. All this was particularly true of the farming previous to the second third of this century, and the apple and standard pear orchards of the country still record the old method. . It has required at least a genera- tion of men in which to thoroughly establish any new agricultural system, and the time is not yet fully arrived for the passing out of the old orchards and the coming in of the new. In other fruits than apples and standard pears, the generations of trees are comparatively short-lived, and those fruits sooner feel the effect of new agricultural teachings. Vine- yards, and orchards of plums, dwarf pears, apricots, cherries and quinces, have mostly come into exist- ence along with the transition movement from the 138 The Principles of Fruit-growing. old to the new farming, and they have been planted seriously, with the expectation of profit, the same as the grain crops have. Peaches had passed out in most parts of the east, and they are now coming in again with the new agriculture. At the present time, men buy farms for the sole purpose of raising fruit, a venture which would have been a novelt3r fifty years ago ; but the habit of imitation is so strong that the apple planter patterns after the old orchards which were grown under another and now a declining system of agriculture, and many of which are still standing on the old farms of the northeastern states. The apple orchard, therefore, upon the one hand, and the well -tilled vineyard upon the other, are the object lessons which illustrate the faults of non- tillage and the gains of tillage. THE PHILOSOPHY OF TILLAGE.* Tillage may be defined as the stirring of the soil for the direct purpose of making plants thrive. Its immediate effect is to ameliorate and modify the soil itself, but its secondary effects are those which are desired, and which are also intimately concerned in the welfare of the plant. For example, tillage is capable of lessening the capillarity of the surface soil, and from this there may result a saving of moisture from evaporation, and it is the moisture *The reader who desires the fullest and best exposition of tillage in its va- rious aspects should consult "The Soil," by King, and "The Fertility of the Land," by Roberts. Benefits of Tillage. 139 which is sought. For practical purposes, however, it is unnecessary to keep this distinction in mind, and we may classify the benefits of tillage under three general heads, arranging them approximately in their order of importance to the fruit-grower: 1. Tillage improves the physical condition of the land, («) By fining the soil, and thereby presenting greater feeding surface to the roots; (b) By increasing the depth of the soil, and thereby giving a greater foraging and root- hold area to the plant; (c) By warming and drying the soil in spring; (d) By reducing the extremes of temperature and moisture. 2.

The simple statements of these offices of tillage is sufficient for the present occasion, except, perhaps, in respect to the improving of the texture of the 140 The, Principles of Fruit-growing. soil and the conservation of the moisture, for if the cultivator is skilled in these latter matters, all the other benefits will follow. The texture of the soil. — The texture or physical condition of the soil is nearly always more important than its mere richness in plant-food. That is, the productivity of land is not determined wholly, and perhaps not even chiefly, by the amount of fertiliz- ing elements which it contains. Thi.s is particularly true of all lands — like the clays — which tend to be- come and to remain hard and unpleasant if left to themselves. Plant-food is of no consequence unless the plant can use it. The hardest rocks may con- tain various plant-foods in abundance, and yet plants cannot grow on them. A stick of wood contains potassium and phosphorus and nitrogen, and yet nothing grows upon it until it begins to decay. A hundred pounds of potash in a stone -hard lump is worth less to a given plant than an ounce in a state of fine division. Soils which the chemist may pronounce rich in plant -foods may grow poor crops.* In other words, the chemist can not tell what a soil will produce; he can only tell what it contains. All this is not surprising, when we come to think of it. Every good farmer knows that a hard and lumpy soil will not grow good crops, no matter how much plant -food it may contain. A clay soil which has been producing good crops for any number of years may be so seriously injured by one injudi » See, for example, Bull. 119, Cornell Exp. Sta. Fertilizers vs. Tillage. 141 cious plowing in a wet time as to ruin it for the growing of crops for two or three years. The in- jury lies in the modification of its physical texture, not in the lessening of its fertility. A sandy soil may also be seriously impaired for the growing of any crop if the humus, or decaying organic matter, is allowed to burn out of it. It then becomes leachy, it quickly loses its moisture, and it becomes ex- cessively hot in bright, sunny weather. Similar re- marks may be applied to all soils, although they are not equally true of all. If these remarks are true, then it follows that it is useless to apply commercial fertilizers to lands which are not in proper physical condition for the very best growth of crops. If potash, for example, were applied to hard lumps of clay, it could not be expected to aid in the growth of plants, because plants cannot grow on such a place. If the same quantity were applied to mellow soil, however, the greater part of it would be presented to the roots of plants at once, and its effects would no doubt be apparent in the season's crop. The improvement of the texture of the soil is not only a means of presenting the plant -foods to the roots of plants and of uniformly distributing what fertilizer may be ap- plied, but it is also a direct means of conserving moisture and of hastening chemical activities. The soil is a vast storehouse of plant -food, and the first effort of the husbandman should be to make this store available to plants. "Men take him for a foole or a mad man that, having store of 142 The Principles of Fruit-growing. wealth in his trunck, doth yet complain of want.

The fact is that they generally need both, if the largest and best crops are to be secured. Drought seems to most people to be one of those calamities in which there are no secondary or inci- dental blessings, and it must be confessed that the lesson of the recurring droughts has not yet been learned by the great body of farmers. The one remedy which occurs to most persons is irrigation, and yet there is sufficient rainfall in most parts of the fruit-growing regions of the country to provide all the needs of large crops. The difficulties are that this rainfall comes when it seems not to be wanted, and very "much of it is allowed to escape by evaporation. The truth is that the heavy rainfall * Samuel Hartlib, "An Essay for Advancement of Husbandry-Learning," London, 1651, p. 3. Saving the Water. 143 usually comes at the best season, for it is the period of inactivity, when the work of the farmer aud the growth of the plants are least interfered with. If we, in the east and south, were perfectly certain that we should have no rain from June until September, we should carefully husband the rainfall of the earlier months, and we should suffer little loss ; but now that we expect rain all summer long, we neg- lect the saving of the early rains, and gamble upon the chance of having a rain when we shall need it. It often happens that the dry countries suffer least for water! How shall we save the water? By holding it in the earth. If the earth is finely divided and yet compact, the capillary pores or interstices will hold enormous quantities of water. If, then, we break up these interstices next the atmosphere, we shall prevent the water from passing off by evaporation. The whole subject of the saving of moisture, there- fore, falls into two means, the catching and holding of it (or the making of a reservoir), and the pre- vention of evaporation. It is, therefore, a question of plowing and then of surface tilling. It will thus be seen how futile it may be to try to save the water by beginning tillage late in the season, when a drought is threatened. If the land has not been well prepared, there may be no water to save by that time. It may either have run through the land into the drains, or it may have evaporated long before the farmer saw the need of saving it. The hard-pan may be so near the surface that but 144 The Principles of Fruit-growing. little water could get into the land; the dish -pan was shallow, and the early rains made mud -puddles or passed off over the surface. Upon such lands, deep plowing is necessary, in order to break up the hard-pan and to increase the storage capacity of the soil. If the land is open and leachy, shallow plowing may be necessary, else the soil may be loos- ened too much. And the water -storage capacity of inost soils may be increased by putting humus — or decaying organic matter — into them. It will thus be seen that the methods of conserving or saving moisture must be worked out — or rather thought out — by each farmer for his own farm. The water of rains and snows is held upon the surface for the time, and allowed to percolate into the soil, if the land is rough and open from recent plowing, if there is a cover of herbage upon the land, or if the surface is soft and mellow. Fall plowing may be advisable in order to catch the water of the inactive season, and also to expose hard soils to weathering, and it may hasten the work of spring. But clay lands with little humus in them may puddle or cement if fall -plowed, and if ban-owed and fitted in the fall ; and in the south all rolling lands are exposed to serious gully- ing by fall plowing. As a general thing, it is not advisable to plow fruit plantations in the fall, how- ever, not only because it may too greatly expose the roots to the weather, but because it prevents the ameliorating of such lands by the use of some in- cidental or catch crop which may be sown after the Tools with which to Save Moisture. 145 summer tilling is done. The winter covering of plants is quite as efficient in holding the precipi- tated water as fall plowing is, and the other ad- vantages of it are invaluable (as explained in Chap- ter IV.). Any body or substance which is interposed be- tween the air and the moist soil will prevent the evaporation of the moisture. The ground is moist underneath a board. So is it underneath a layer of sawdust or of ashes ; and so is it underneath a layer of two or three inches of dry earth. It is expensive and difficult to haul this dry earth onto the land, and, moreover, it soon becomes hard and dense, and is no longer a mulch. It is better to make the mulch on the spot by shallow cultiva- tion, and to repair the mulch as soon as it be- comes hard and crusted. The orchardist will, there- fore, till as often as the land needs it, however frequent that may be ; but as a general statement it may be said that fruit- lands ought to be tilled every ten days and after every rain. USE OF THE VARIOUS TOOLS IN RELATION TO CONSERVATION OP MOISTURE.* Plowing to save moisture .—The first step in the conservation of moisture must be the preparation of the land so that the rain will sink down, and not be carried off by surface drainage. In many sec- * Adapted from L. A. Clinton, Bnll. 120, Cornell Exp. Sta. For a fuller diteussion of the subject, consult Roberts' "The Fertility of the Land." 146 The Principles of Fruit-growing. tions of the country, especially in the southern states, the great bane to agriculture is the surface washing of the soil. Owing to shallow plowing and shallow . cultivation, the water is unable to set- tle into the hard soil with sufficient rapidity, and is carried along the surface, producing those gullies which are there so destructive to farm lands. * The improvements in the plow have done much towards remedying these defects, but there is still much ignorance as to the proper use of this imple- ment. As an implement to be used in the prepa- ration of the soil for the reception of moisture, it stands pre-eminent. Good plowing does not con- sist— as ordinarily supposed — in merely inverting a portion of the earth, but in pulverizing and fining it and burying the sod or refuse which may be on the surface. The amount of water which a soil is capable of holding depends directly upon the fineness of its particles. Then that plow which will break and pulverize the soil most thoroughly is the one best adapted to fit the soil for holding moisture. This point is well illustrated by King in NOTE.— Pigs. 13 and 14 (pages 147 and 148) are designed to illustrate some of the leading types of tools which are used for tilling fruit-lands. It is not the purpose to recommend these particular tools over any others, or, in fact, to recommend them at all ; but simply to show the reader the range of forms which are in common use. Fig. 13.

Saving Soil Moisture. 149 ''The Soil." He says: "Since each independent soil grain of a moist soil is more or less completely surrounded by a film of water, it is evident that, other conditions being present, the largest aggre- gate surface area may retain the most water per cubic foot. Now, a cubic foot of marbles one inch in diameter possesses an aggregate surface of 27.7 square feet, while if the marbles were reduced in diameter to one -thousandth of an inch, then the total area per cubic foot is increased to 37,700 square feet." From this it is evident that the total amount of water capable of being absorbed by a soil which is cloddy and lumpy is very slight in comparison with what it would be were it in a finely divided state ; and not only is its absorbing power less, but its power of holding moisture is also greatly reduced. A large amount of water is lost during the winter and spring months, owing to the surface drainage of melting snows and heavy rainfalls. To prevent this loss, fall plowing may be prac- ticed, and when the subsoil is very hard and com- pact, the use of the subsoil plow may prove most beneficial. Should the ground break up in clods, then it may be allowed to remain during the winter without harrowing, to more thoroughly sub- ject it to the beneficial action of the elements. But if the soil is in good mechanical condition, and in fruit- land, plants should be growing on it during the winter. Harrowing to save moisture. — The harrow, besides 150 The Principles of Fruit-growing. pulverizing and fining the soil for the seed-bed, is most efficient in furnishing an earth -mulch. The spring -tooth harrow is in reality a cultivator, and its action is similar to that of the cultivator. When used as an instrument to conserve moisture, the teeth should penetrate to the depth of about three inches, and to produce the best effect the ridges left by it should be leveled off by a smoother, which can now be purchased as an attachment to the harrow. The tillage of orchards by the harrow is now practiced extensively, and nothing short of irrigation will so nearly meet the demands of trees for moisture, particularly upon the heavier soils. The Acme harrow is a most excellent implement on soils which are comparatively free from stones and rubbish. The plow -like action of its blades serves to pulverize the soil, to spread the mulch evenly, and it leaves a most excellent seed-bed. The cutaway or disc harrows may be either bene- ficial or of absolute injury. If the discs are so set that they cover but a portion of the surface with the mulch, they leave a ridge exposed to the action of the wind and sun, and the rate of evaporation is greatly increased. The discs should be set at such an angle that the whole surface shall be stirred or covered. Their chief value lies in their cutting and pulverizing action on clay soils, but as conservers of moisture they are inferior to the Acme or the spring -tooth. Soils which need the disc harrow to pulverize them should generally be gone over again with some shallower tool. Cultivating to Save Moisture 151 The mellower the soil, the lighter should be the work done by the harrow. On most heavy orchard soils, it will be found necessary to use the heavy tools, like the spring-tooth and disc harrows, in the spring, but if the land is properly handled it should be in such condition as to allow the use of a spike -tooth or smoothing harrow during summer. This light summer harrowing should be sufficient to keep down the weeds, and it preserves the soil- mulch in most excellent condition. With such a tool and on land in good tilth, a man can harrow ten or more acres a day. Cultivators and conservation of moisture. — The ac- tion of cultivators is not materially different from that of the spring -tooth harrow. The size of the teeth should be regulated by the work to be per- formed, an implement with many small teeth being preferable to one with a few large teeth, when the ob- ject is to conserve moisture. It must be borne in mind that in a dry time the less surface exposed the less will be the evaporation. If a large-toothed im- plement is used to destroy grass and weeds, then it should be followed by a smoother to reduce the ridges and prevent loss of moisture. Ridge culture is only allowable when the object is to relieve the soil of moisture on bottom lands where the water comes very near the surface, or for some special crops, where a high degree of warmth is required early in the season. In these cases, it rn^y be necessary to throw up ridges to produce the proper degree of warmth for germination, but even then the ridges 152 The Principles of Fruit-growing. should be slight. Nothing could be better calculated to dry out a potato field or a corn field than throw- ing the ground up in high ridges, leaving a large surface exposed to the action of sun and wind. In fruit plantations which are in a proper state of cultivation, a small -toothed or even spike -toothed cultivator will be found sufficient to maintain the surface mulch. The roller, in Us relation to soil moisture, is an implement whose value depends largely upon local conditions. There is no tool which requires more judgment as to its proper use. On light, loose, sandy or gravelly soils, where every effort must be made to solidify and pack the particles closely to- gether, the roller must be used repeatedly. The difficulty with such soils is that the spaces between the grains are so large that the water is permitted to pass through freely, and is lost by percolation. The capillary openings are so large that there is very feeble rise of the water to take the place of that used by plants and lost by evaporation. The roller lessens the size of these pores in solidifying the soil, and the capillary force is then strong enough to draw the water to the surface. If, now, the soil is left in this condition, it has been put in the best possible form for parting with its moisture into the atmosphere, and it will take ad- vantage of the opportunity unless prevented by establishing a surface mulch. In seeding land in a dry time, the soil should be rolled in order to bring sufficient moisture to the seeds to insure germina- Rolling and Smoothing. 153 tion. When circumstances will permit, the roller should be followed by a smoothing harrow, that the surface mulch may be restored and the moisture stopped before reaching the atmosphere. On clay lands the roller must be used with much caution. If used immediately after grain is sown and a heavy rain follows, there is danger of the soil becoming so compact on the surface that the tender shoots are unable to get through, and the most direct con- nection is established between the soil moisture and the air. A good method of treatment for clay is to roll before the seed is sown, then harrow and Fig. 15. A pluuker or float. make a good seed bed, and then drill in the grain. After the plants are well up the roller may be used again, which will bring the water to the surface, where the growing plants can make use of it before it passes off by evaporation. Various kinds of plankers or floats may be used in the place of the roller to smoothen and compact recently tilled lands. A good tool of this kind is shown in Fig. 15. "To make this cheap and easily- made adjunct to good cultivation, take two hard- wood planks, 2x8 inches and 7 feet long, and 154 The Principles of Fruit-growing. notch them as in the cut, boring a hole at the upper end to hitch to; the notches should be 8 inches apart and 2 inches deep ; now nail cross planks on the two notched bed pieces, using the same sized pieces, 2x8 and 6 or 7 feet long ; let the cross planks project 1 foot at each end over the bed pieces. If more weight is needed to fine the clay lumps, the driver can ride the float, or weights can be placed on it. I go over with this float when seeding to grass, and also in fitting strawberry ground. I prefer it to a roller, as it leaves the surface smooth and fine."* SUGGESTIONS FOB THE TILLING OF FRUIT -LANDS. Lands which enjoy perfect natural drainage are particularly desirable for orchards, because they are not only warm and give up their fertility easily, but because they also allow of very early cultivation, which is an important requisite in the management of orchards. If this perfect natural drainage does not exist, tile-drainage should be employed until the soil is brought into the best possible condition. It should be said that many hard and wet soils make excellent pear and plum lands when thoroughly tile- drained. It is a common opinion that only flat lands need draining, but one often finds rolling lands in which the subsoil is high and hard, and holds the water like a dish -pan. Judicious draining not only carries off the superfluous water, but it also *H. L. Barton, in Fruit; quoted in Market Garden, Apr., 1897. Subsoiling. 155 loosens the subsoil and allows it to retain its mois- ture better in times of drought. An attempt should be made to bring the land in the various parts of the orchard into conditions as uniform as possible, so that the same tillage and treatment may be ap- plied to the entire area. All hard and "sour" spots should receive particular care in drainage and subju- gation, or they should be left outside the plantation. Lands which have hard and impervious subsoils should be plowed very deep before trees are put upon them ; and in some cases, as for dwarf pears, it may pay well to use the subsoil plow. It should be borne in mind, however, that the subsoil plow is not always a fundamental corrective of hard subsoils, for it does not remove the cause. The subsoil may gradually settle back into its old condition, and land cannot be completely subsoiled after it is planted to trees. In the case of strawberries, raspberries, and other short -rotation fruits, the subsoil plow may be used at frequent intervals; but in lands which are to be planted to orchards, the tile drain is a more per- fect ameliorator of the subsoil than the subsoil plow- is. Yet even the one subsoiling may serve a use- ful purpose in sending the roots downwards at the start, and this advantage will be the greater when the superfluous water removes itself rapidly from the hard-pan. The soil in which orchards are set should always be in a thorough state of cultivation at the time the trees are planted; that is, whether in sod or in hoed crops, the land should be in good tilth or physical 156 The Principles of Fruit-growing. condition, fertile, and free from hard or "sour" places and pernicious weeds. There are exceptions to this rule in the case of certain rocky or steep lands upon which it is desired to set apples; but for all orchards which are planted directly for commercial results, this advice has few, if any, exceptions. It is gener- ally best to put the land into hoed crops the sen son before the trees are set, as potatoes or corn; although sod land, if well fitted and naturally in good heart, often gives excellent results when turned over and set at once to orchards. But most soils need the previous cultivation to bring them into a mellow and uniform condition. Many of the "bad places" in or- chards, where trees die out the first two or three years, could have been discovered and corrected if the land had been devoted to one or several hoed crops, for the owner would have observed that they were too wet or too lumpy, or had other serious de- fects. Lands look more uniform when in sod than when cultivated, and the farmer may be led to over- estimate their value for orchard purposes. It may also be said that the familiarity with a particular piece of land, which comes of frequent cultivation, enables the careful grower to judge accurately of its adaptability to particular fruits or even to special varieties. The best tillage is that which begins early in the season, and which keeps the surface stirred until late summer or early fall, and the best implements are those which secure this result with the least amount of time and labor. For the first few years, it is gen- Plowing Orchards. 157 erally advisable to turn the land rather deep with a plow at the first spring cultivation. For the subse- quent cultivation of the season, there are many styles of clod crushers, spring- tooth harrows, cut-aways and smoothing harrows, which adapt themselves readily to the cultivation of the particular soil in question. There is no single style of tool which is best for all soils or for all years. As a general statement, it may be said that for all heavy lands the fruit-grower needs four types of harrows,— the cut-away, or spading -harrow type for hard land, and the first spring work ; the spring -tooth type, the Acme or clod -crusher type, and the smoothing -harrow type. The last is to be used only to make and maintain the surface mulch after the land has been got in fine tilth. In all friable or loose soils, shallow cultivation is always preferable. When the land is once in good condition, but little effort and time are required to run through the orchard. Crust should never be al- lowed to form upon the surface, and weeds should be killed before they become firmly established. The entire surface of the orchard should be thoroughly stirred as often as once in ten days or two weeks whilst the tillage lasts. In general, level culture is best. This is secured by plowing one year to the trees and the following year away from them; one year north and south, and the next year east and west. It is somewhat difficult to plow away from large trees, however, and with the cultivators or harrows now in use, it is easy to work the soil away by subsequent cultivation, allowing the 158 The Principles of Frnit- growing. furrow to be thrown towards the tree each spring, particularly if the land is in good tilth; but it is al- ways advisable, upon fairly level ground, to plow the orchard in opposite directions in alternate years. Land which is so wet that it needs to be thrown permanently into ridges for drainage is not often adapted to fruit. The difficulty of working close to the trees has had the effect of en- couraging too high pruning. There is a tendency to start tops too high rather than too low, thereby exposing great length of trunk to injuries of sun and wind, and elevating the top beyond the reach of pickers and of sprays. For most trees the ideal length of trunk is under five feet rather than above it, and implements now in the market allow of this lower training. Trees which have low tops, or which hang low with fruit, can be reached by separating the halves of any of the double Fig. 16. Set-over harrows by means of a long dou- beam vineyard plow, bletree, so that the halves, when ad- justed, run from four to six feet from each other. A cut-away harrow rigged in this manner will work away the back -furrows from under the trees during the season. All cultivators or harrows with high handles, wheels or levers should be discarded if orchards are worked when the limbs Tillage of the young Orchard. 159 bend low with fruit. An implement of the grape - hoe type may be used with advantage in some eases to loosen the earth about the trees. A single -horse plow, with a set-over beam (as in Fig. 16), is also most excellent for plowing close to trees and bushes. The objection to medium -low heads to trees arises from the use of the old-fashioned implements of till- age, and also from a misconception of what the plowing of an old orchard should be, for if the or- chard is properly cared for in its earlier years, heavy plowing will not be needed in its later life. This labor of working about trees is greatly facil- itated by the use of harnesses which have no metal projections. There should be no names with elevated tops, and the turrets on the back -pads should be simply leather loops. The back -pad itself should be reduced to a single wide strap entirely devoid of wadding. Harnesses of the Sherwood type, with no traces, but drawing by a single chain between the horses, are excellent in orchards, as they require no whiffletrees, and they are likewise handy and efficient. The better the plowing and other tillage of the orchard in the first few years of its life, the easier and more efficient the subsequent plowing will be. If care is taken to keep the land friable and well -filled with humus, it may not be necessary to turn furrows at the spring plowing after four or five years. Per- sons commonly suppose that an orchard must be plowed the same as corn or potato ground is, by in- verting the land and running regular furrows ; but inasmuch as the object is simply to keep the land 160 The Principles of Fruit -growing. mellow on top, and not to get a crop into it, heavy plowing is not essen- tial. Very often some of the heavier harrows or light gang- plows may be used to tear up the ground in spring, if the land has been got into proper shape when the plantation was young. This is especially true in light lands upon which peaches are generally grown. If cover crops are to be plowed under, these remarks will not apply with equal force. In the first few years, however, it is essential to plow moderately deep in order to break up the soil and to send the roots down, as explained farther on. A world of trouble with the orchard will be saved if the suggestions in this paragraph are fully understood. Specific remarks.— 1. Begin to till when the orchard is planted, and till the entire surface. If trees are prop- Root -growth in Trees. 161 erly set, and if cultivation is begun the first year, the roots will go deep enough to escape the plow. The roots of trees spread much farther than the tops. I will give some examples from trees of which we have carefully measured the tops and roots. Fig. 17 shows a standard Howell pear tree set in 1889 and photographed in 1895. It grows on a hard clay knoll. The full spread of the top is seven feet. Two roots were laid bare, and they ran off in one direction to a distance of twenty-one feet. Assuming that they ran an equal distance in the other direction, the spread of roots was forty-two feet, or just six times that of the top. And yet it is commonly said that the spread of roots and tops is about equal! Now, these roots were long and whip -like. The soil was so poor that they were obliged to search far and wide for pasture. Compare Fig. 18. This is a Fall Orange apple, also set in 1889, in rich, well tilled soil. Here the roots are in good pasture, and they remain at home; yet their spread is twice that of the top. The top of this tree had a diameter of eight feet, and we followed the roots eight feet upon the side in which we dug. These object lessons enforce the im- portance of tilling all the land between trees. But these figures teach another lesson. Even at their highest point, the roots of Fig. 17 are eight inches below the surface. They escape the plow. A like remark applies to Fig. 18. Now look at Fig. 19. This tree is the same age as the others, but has always stood in sod. The roots ran ten feet in one direction and the total 162 The Principles of Fruit-growing. spread of the top was six feet ; but the roots lie just underneath the surface. This land could not be plowed without great injury to the tree. Let us consider the relation of this tree to moisture: the roots are in the dri- est part of the soil ; the grass is pumping out the water and locking it up in its own tissues and sending it into the at- mosphere with great ra- pidity ; the soil is baked, and pulls up the water by capillary attraction and discharges it into the air ; there is no tillage to stop this waste by spreading a mulch of loose and dry soil over the earth. If Fig. 18. Roots of a young apple tree in rich tilled land. one were to sink a well under this tree and were to erect a windmill and pump, he could not so completely deprive the tree of moisture! And the Tillage in Young Orchards. 163 less moisture, the less food! And yet this is a com- mon method of treating fruit -trees! In young orchards, then, it is commonly best to plow rather deep — say six to eight inches— in order to send the roots down. Of course, the plow should not be run deep close to the trunk of the tree. The careful plowman will turn out his plow when he comes within a couple of feet of the tree. This deep plowing for a few years will ameliorate the land, establish the root -habit of the tree, and obviate the necessity of laborioiis plowing in after years. 2. Tillage should be be- gun early in the season, in orchards. Trees com- plete most of their growth by the first of July. Early tillage saves the moisture Fig. 19.

All catch crops on the orchard should be plowed under just as soon as the ground is dry enough in the spring, for these crops soon pump the water from the soil and cause it to bake and cement together, and the longer they remain the more difficult it is to cause them to rot when turned under. Hard and woody herbage, plowed under late in the season, may remain as a foreign body in the soil all summer, breaking the connection be- tween the upper and the lower soil, and thereby preventing the upward movement of the water and causing the top soil to completely dry out. The chief value of crimson clover, rye, or other catch crop in the orchard lies in its fall growth and its protection of the soil in winter, not in its growth in spring. Few people are aware that the season of growth in most woody plants extends scarcely to midsum- mer. It is worthy of note that most, if not all- native trees and shrubs cease growing very early in the season. This is no doubt one reason why they are able to endure the winter. Plants which cease growing early, and which mature their wood well, are often said to be determinate in their growth, Early Growth of Trees. 165 while those of opposite habit are said to be inde- terminate. It is, of course, apparent that plants of indeterminate growth are not hardy, as a rule. A series of careful measurements of growth was made upon various trees and shrubs at Lansing, Michigan, in 1886, and some of the records are presented be- low.* The last date in each case designates the ter- mination of growth for the year. It will be observed that very few of the plants grew until July. This fact is illustration and proof that in our rigorous climate cultivation should stop early, and that it should be vigorous at the opening of the season. RECORDS OF GROWTH.!

The drought may have checked growth to some degree, although it did not become severe until the end of June. Most of the plants stood upon the eampus, with no cultivation. A few were younger, and stood in the rows of a closely planted arboretum, where they received occasional cultivation, or in a newly-pl anted group, where the soil was frequently hoed; these plants are designated by asterisks. 166 The Principles of Fruit-growing.

It can spare some of the moisture which comes with Mistakes in Orchard Culture. 169 the fall rains. We may, therefore, sow some catch or cover crop. (See Chapter IV.) 4. Till in such manner that the land shall be in uniformly fine tilth. Every good farmer knows that the value of his crop depends more upon the tilth of the soil than upon the mere richness of it. Fer- tility is largely locked up in poorly tilled lands. Orchards which are plowed late in spring are usu- ally in bad condition all the season, especially if the soil is clay. Fall plowing upon stiff and bare lands is apt to result in the puddling of the soil by the rain and snow, as already explained; if there is sod on the land, this injury is less likely to follow. In general, it is best to let orchard lands pass the winter under a catch crop. 5. Remember that tillage may be overdone. Trees may be made to grow too much wood, and there- fore too little fruit, and they may be sent into the winter in soft and unripened condition. If land is in good tilth, as it is when in best condition for the growing of potatoes or melons, tillage beyond that needed to conserve the moisture is useless ; and even this conservation -tillage may well stop in late summer in very many cases, as already indicated It is a common practice to severely head -in trees which are making a too vigorous growth, but this practice usually aggravates the difficulty rather than corrects it. The fundamental treatment for such trees is to check the growth by some means, as by lessening the tillage or by withholding stimulating fertilizers. 170 The Principles of Fruit-growing. CROPPING THE ORCHARD. It will now be asked what crops may be grown in the orchard. Grain and hay, never! Any hoed crop may be used for the first few years ; but it must be remembered that every crop competes with the trees for food and moisture, and whatever may befall the crop, the trees should not be allowed to suffer. An open space should be left about the tree, free of crops, at least several feet in extent. As a general statement, it may be said that a space three feet wide should be left upon all sides of the tree the first year, and this area should be enlarged a foot or two each year ; and this space should con- tinue to enlarge until the trees occupy the entire sur- face. Corn and some other luxuriant plants appro- priate moisture more quickly than the tree can. In general, some low -growing crop which demands good tillage and comes off the land early is best. The notion that young trees should be shaded by a <-rop is probably erroneous for most regions. In orchards set less than twenty feet apart, the land should rarely be cropped after the third year ; but apple orchards, if well cared for, may be cropped lightly for seven or eight years. In no case should the grower expect to secure as much crop upon orchard land as upon other areas ; and the drier the land, the less should it be cropped. When the orchard comes to bearing age, give it the entire land. Thereafter, the most profitable secondary crop to raise is cultivators. Crops for Fruit Plantations. 171 In general, it may be said that only those crops are allowable in a fruit plantation which demand such treatment as to improve the land for the fruit plants. The growing of light crops is a means of keeping the land stirred when it might otherwise be neglected ; and if the grower is careful to see that the physical condition of the land is improved, and adds enough plant -food to supply the loss, the light Cropping of orchards for the first few years may be a decided benefit. At all events, cultivated crops are better fhan sod. The danger is that the fruit- grower will continue the cropping too long, and «ixpect too much from it. In an orchard, the crops ought to pay for taking care of the land until the trees come into bearing. Strawberries and the bush fruits may be advantageously set in alternate rows with beans or potatoes, and the same tillage is re- quired for each crop. Only annual crops should be grown in fruit plan- tations. The growing of nursery stock in orchards —a frequent practice in parts of the north— should be discouraged.* This crop makes essentially the same demands upon the land as the orchard itself, and it does not allow of those variations in culti- vation and management which may be essential to the varying seasons. It may be true that enough fertilizer can be placed upon the land to replace the loss of plant -food, but it is rarely done ; and, more than this, the nursery stock drinks up the moisture *The double-planting of fruit lands— the mixing of different kinds of fruits -is discussed in Chapter V, 172 The Principles of Fruit-growing. which should be used by the orchard. Nursery stock is known to be particularly hard upon land, so much so that nurserymen seldom grow two crops of fruit-tree stocks in succession upon the same area; but this injury to the land is an impairment of phj'sical condition rather than exhaustion of plant- food. (See Chapter IV.) Sod may sometimes be allowed in an orchard if it is closely pastured, but hay should never be cut. Sod lands are not only drier than cultivated ground, but they are favorite breeding places of insects. Borers are particularly bad in grass land. No stone fruits should ever be allowed to stand in sod, and the same may be said of dwarf pears. Apples and standard pears may now and then be seeded with safety, but it is certainly true that, in general, fruit decreases in proportion as sod increases. Very thrifty young apple and pear orchards may sometimes be thrown into bearing by seeding them down for a time, but the sod should be broken up before the trees become checked in vigor. The whole question as to whether sod is hurtful or beneficial to an orchard is a local one. The grower must determine it for himself. If the orchard is in sod and is not doing well, the best advice in general is to plow and till it. Certainly it is better to make tillage the rule and sod the excep- tion, than to start out with the intention of growing an orchard in grass and cultivating it only when forced to do so. It is better to pasture an orchard than to allow the grass to grow at will, but close pasturing can by no means take the place of tillage. Remedy for Unprofitable Orchards. 173 If one wants to raise hay or grain, it is cheapest to grow it where there are no trees to bother. If he wants to grow apples or grapes, he had better choose some other place than a meadow or grain field. The use of clover and other temporary cover crops as a means of fertilizing the land is another matter, and is discussed in the next chapter. Most apple orchards are in sod, and growers are always asking if they shall be plowed up. If the growers of apples are satisfied with the crops, let the orchards alone ; but if it is thought that better crops are desirable, do not hesitate to make an effort to obtain them. It is surprising that the disastrous fail- ures of recent years have not awakened farmers to the necessity of really doing something for their orchards. Now and then an enterprising man makes an energetic attempt and is rewarded, but the greater number continue to exercise the most thoroughgoing neglect and to bewail the failure of the crop. Yes, plow the old apple orchard ; then fertilize and spray it. Or, if the roots are too near the surface to allow of plowing, harrow it thoroughly when the turf is soft in spring, and continue to work it during the season. If this is not feasible, then pasture it closely with sheep or hogs, feeding the stock at the same time. If this cannot be done, and the orchard is unprofitable, cut it down. When orchards begin to bear well, the crops should be discontinued. Young orchards may some- times be summer -fallowed with the very best results if the land is hard and intractable. This fallowing 174 The Principles of Fruit-growing. is clean cultivation. This is often the quickest and cheapest way of bringing such lands into fit condi- tion for the growing of the fruit, and the longer the process is delayed after the plants are set, the more difficult and the less efficient the labor will be. This summer -fallow should be begun very early in the season and continued until midsummer, at which time some cover crop may be sown. CHAPTER IV. THE FERTILIZING OF FRUIT LANDS. ANY land which is fit for the growing of crops will maintain a fruit plantation throughout its exist- ence without the addition of plant -food, and enable the trees to produce at the same time a normal quan- tity and quality of fruit. But the profit in fruit- growing lies in securing the extra normal or superior quantity and quality, and this result demands fertiliz- ing of the land and every other good care. How much plant -food the farmer should add to his land depends upon the amount of increase or profit which he secures. It is a matter of business, an item of profit and loss. If the fruit-grower applies five tons of fertilizer to every acre and secures a profit on the investment, the quantity is none too large ; but in many instances it is a loss of the material to add anything. The successful merchant is the one who is dissatisfied with a normal and common trade, but he forces the demand by attracting and interesting his customers beyond the point of their actual needs. There are many causes which contribute to the unsatisfactory results of applying fertilizers, but the commonest one is lack of proper tillage and prepara- tion of the land. Poorly-tilled land, as we have (175) 176 The Principles of Fruit-growing. seen, not only refuses to yield up its own stores of wealth, but it will delay and even preclude the good results from plant -foods which may be added to it. The first thing to do, then, is to make it possible for the plant to grow. Make the physical and en- vironmental conditions right, and the addition of plant -food will be felt and appreciated. The plant must be made comfortable before it will thrive. A cow will not relish even the fanciest ration if she shivers with cold. The grower must set himself in line with nat- ural methods. He must see that the soil has a good supply of humus or decaying organic matter (got from crops turned under, dressings of stable manure, muck, and the like), and that it generally has some cover upon it. Early in the season, this cover is the surface mulch of cultivated soil, and later it is the cover crop of rye or crimson clover, or something of the kind. Nature is a kindly and solicitous mother. She knows that bare land becomes unproductive land. Its elements must be unlocked and worked over and digested by the roots of plants. The surface must be covered to catch the rains and to hold the snows, to retain the moisture, and to prevent the baking and cementing of the soil. The plant tissues add fiber and richness to the land, and make it amenable to all the revivifying influences of sun and rain and air and warmth. The plant is co -partner with the weather in the building of the primal soils. The lichen spreads its thin sub- Evolution of Soils. 177 stance over the rock, sending its fibers into the crevices and filling the chinks, as they enlarge, with the decay of its own structure ; and finally the rock is fit for the moss or fern or creeping vine, each newcomer leaving its impress by which some later newcomer may profit. Finally the rock is disinte- grated and comminuted, and is ready to be still further elaborated by corn and ragweed. Nature intends to leave no vacant or bare surfaces. She providently covers the railway embankment with quack -grass or willows, and she scatters daisies in the old meadows where the land has grown sick and tired of grass. If one pulls up a weed, he must quickly fill the hole with some other plant, or nature will tuck another weed into it. Man is yet too ignorant or too negligent to care for the land, and nature must still stand at his back and sup- plement the work which he so shabbily performs. She knows no plants as weeds. They are all equally useful to her. It is only when we come to covet some plant that all those which attempt to crowd it out become weeds to us. If, therefore, we are competent to make a choice of plants in the first place, we should also be able to maintain the choice against intruders. It is only a question of which plants we desire to cultivate. We must keep the land at work, for it grows richer and better for the exercise. A good crop on the laud, aided by good tillage, will keep down all weeds. The weeds do not "run out" the sod, but the sod has grown weak through some fault of 178 The Principles of Fruit-growing. our own, and thus the dandelions and plantains find a chance to live. So the best treatment for a weedy lawn is more grass. Loosen up the poor places with an iron garden rake, scatter a little fertilizer, and then sow heavily of grass seed. Do not plow up the lawn, for then you undo all that has been accomplished ; you kill all the grass and leave all the ground open for a free fight with every ambitious weed in the neighborhood. If the farmer occupies only half the surface of his field with oats, the other half is bound to be occupied with mustard or wild carrot or pigweed ; but if his land is all taken with oats, few other plants can thrive. So, a weedy farm is a poorly farmed farm. But if it does get foul and weedy, then what ? Then use a short, quick, sharp rotation. Keep the ground moving or keep it covered. No Russian thistle or live -for -ever or jimson-weed can ever keep pace with a lively and resourceful farmer. THE LESSON OF NURSERY LANDS. The injurious effects of leaving soils bare, and of tilling at untimely seasons, are well illustrated in most nursery plantations. The best nursery lands are the "strong" lands, or those which con- tain a basis of clay, and these are the ones which soonest suffer under unwise treatment. The nur- sery land is kept under clean culture, and it is, therefore, deeply pulverized. There is practically no herbage on the soil to protect it during the winter. Depletion of Nursery Lands. 179 When the crop is removed, even the roots are taken out of the soil. For four or five years, the land receives practically no vegetation which can rot and pass into humus ; and then, the trees are dug in the fall, often when the soil is in unfit condition, and this fall digging amounts to a fall plowing. The soil, deeply broken and robbed of its humus, runs together and cements itself before the following sum- mer ; and it then requires three or four years of "rest" in clover or other herbage crop to bring it back into its rightful condition. This resting period allows nature — if man grants her the privi- lege—to replace the fiber in the soil, and to make it once more so open and warm and kindly that plants can find a congenial root -hold in it. The following synoptical sketch of the causes of the so-called wearing -out of nursery lands will serve to bring the question of productivity of lands into its proper relationships and perspectives:* a. The fertility of the noil. — There are two analytical means of determining the fertility of the land. One method deter- mines the chemical constitution, and the other the mechani- cal or physical condition. Chemistry determines the amount and kind of plant-food in the soil, but it cannot tell just how useful this food may be to the plant. This depends upon the physical condition of the land, or upon the relation of the soil to warmth, moisture, air and mechanical constitution. The plant is not simply a passive agent, taking in the food which is pre- sented to it, but it is actively engaged in searching for and appropriating food. * L. H. Bailey, before American Association of Nurserymen, at Chicago, as reported in Garden and Forest, June 24, 189B. 180 The Principles of Fruit-growing. The actual fertility of the soil depends, therefore, upon the plant as well as upon the land. The better and more comfortable the plant, the more food it can appropriate from a given soil ; hence that soil is practically the richer. The chemist does not determine the physical conditions which make the plant comfortable and active. In other words, the amount of plant-food in the soil is only one of the ele- ments in the fertility of the land. In most instances as much depends upon the physical condition of the soil as upon its chemical constitution, and in many cases even more depends upon it. Soil is derived from two sources — rock and organic mat- ter. Each is essential to it. Without the rock matter it would lose body and staying qualities. Without the organic matter it would lose life, or "heart" and activity. Nature adds the organic matter to the soil by growing plants upon it and then incorporating their remains with it. Everywhere the process of soil -building is now going on. The longer the soil is in crops the richer it becomes, al- though the relative amount of mineral matter which it con- tains may be decreasing at the same time. Nature makes the soil richer, then, both by fining and digesting the mineral matter and by ameliorating its physical condition through the incorporation of humus or organic matter. This fining process must ultimately cease, but the addi- tion of humus never ceases. The final and complete en- richment of the soil, therefore, must come largely as the result of the incorporation of humus with it. The chief value of this humus is not to directly afford plant-food, but to improve the conditions of temperature, moisture, aeration and the like. b. Man's treatment of the land. — Man's chief desire is to use the organic products of the land. He consumes the plant product. As a consequence, cultivated soils soon tend to become hard, dense, heavy and lifeless, and the more clay- like the land the more pronounced is the result. The Best Nursery Lands. 181 The best and richest farm soils are those which are loamy — that is, those which are friable, soft and dark-colored. This loamy condition is brought about largely by the ad- dition of stable -manures and green crops. Every ordinary soil tends to lose its humus sooner than its mineral plant-food, and most so-called exhausted soils are injured in their physical condition rather than exhausted of their fertility. It follows, therefore, that the addition of mere plant-food cannot entirely restore the generality of worn-out lands. The physical condition must always receive first attention. The addition of concentrated fertilizers is not a fundamental corrective of poor lands in the vast majority of cases. It should be considered as a supplement to the treatment of the land by means of tillage and cropping. If man's reward from the cultivation of the laud is so unlike nature's, it follows that one cannot copy the prac- tices of nature in the treatment of the land. Yet, in every generation, there are men who proclaim that because nature neither plows nor tills, therefore man should not. The only infallible guide to the proper treatment of the soil is experi- ence, not mere science, nor speculation ; but science explains the laws and directs the application of them when once ex- perience has discovered them. In fact, experience is law, for experience that persists is that which gives consecutively uniform results under like con- ditions. All experience proves that frequent tillage and the addition of humus quickly and invariably ameliorate and im- prove the soil. It is folly to attempt to controvert the facts by mere speculation. On the other hand, experience proves that the addition of chemical fertilizers does not invariably visibly benefit the soil ; therefore, the value of such applica- tions must depend upon local or transient conditions. c. Tlie nursery lands. — The best nursery lands, at least in New York state, are those which contain much clay. This soil is the most easily injured by unwise or careless treat- ment and by the loss of organic matter. 182 The Principles of Fruit -growing. The nursery crop occupies the land for three to five years. During all this time the land receives no addition of organic matter, and finally even the roots are taken out of it. In very many cases the trees are planted and dug when the soil is wet or very dry, and, it is therefore, quickly and very se- riously injured in its "grain," or its physical condition. Nurserymen find that if the land is rested in clover or grass for a few years it will again grow trees. This rota- tion, like all others, is a means of ameliorating the physical condition of the soil as well as the chemical condition of it. A part of the rotation must aim at the incorporation of humus. Therefore, every famous rotation has a "rest" crop in it. An incidental advantage of any rotation is the variety of tillage imposed by it. A rotation of tools and of methods and seasons of working the land, is often as important ;;s the other results of alternate cropping. Extended figures of chemical analyses* of nursery stock show that the amounts of potash, phosphoric acid and nitro- gen which such stock removes from the land is really very small, and less than that removed by similar bulk or weight of corn or wheat. Experiments now being made show that the addition of concentrated or chemical manures to heavy nursery lands does not promise very important results ; but there are greater hopes from experiments in the sowing of crimson clover and other cover crops in the nursery rows, and in the use of stable manures. There are instances of excellent results following the addition of stable manure to nursery lands between the trees in the fall. One piece of land so treated has grown excellent plum trees for twenty consecutive years. There is no necessary reason why nursery stock should not follow nursery stock as well as wheat fol- low wheat, except that the land is usually more clay-like, the rotation or cropping is longer, and the addition of humus or fiber to the soil is less. d. The conclusions. — The difficulty, then, is not one of amount •Consult 10th Rep. N. Y. State Exp. Sta. (1891), and Bull. 103, Cornell Exp. Sta.; also Rep. Amer. Assoc. Nurserymen, 1896, 43-45. Treatment of Nursery Lands. 183 of plant-food so much as of the availability of that food by improving the physical conditions of the soil. The soil must be warm, soft, mellow, and the plant must be comfortable. The trouble is, not that nursery trees take so much from the soil, but that the rotation is too long, the fiber is burned out of the soil, and much of the working of the land is untimely. Certain lands are not readily injured by nursery cultiva- tion, and these may grow several continuous crops of trees. Now and then the nurseryman can augment the growth of his stock by extra attention to tillage (it is assumed that he always tills well), and by the addition of some quick nitrogen compound, as nitrate of soda ; but these are gener- ally only temporary correctives. The complete or fundamental corrective for nursery land is rotation ; but the length of this rotation may often be shortened, or even entirely re- duced, by the judicious intercultural use of stable manures and cover crops. The conclusion was made that the physical condition of the soil is a subject of greater or earlier importance than its chemical constitution ; that the value of rotation of crops lies largely in its ameliorating effect upon the physical con- dition, and that nursery lands are no exception in demand- ing such rotation. Instead of thinking it strange that trees do not readily follow trees, we should rather think it strange if they did. Because the crop is of several years' duration, it becomes necessary that the alternating cropping should also be extended. A system of rotations must be practiced in blocks of years, not in single years. But this alternating cropping can be greatly shortened by giving greater attention to the addition of fiber to the soil while the nursery stock is growing. There are instances in which the alternation may be made short, and some in which there need be hardly any. Professor Bailey said that he did not look for a gen- eral corrective of the depletion of nursery land, therefore, by the addition of concentrated or chemical fertilizers, but by better management of the lands. 184 The Principles of Fruit-growing. COVER CROPS. A cover crop* is one which is used for the par- ticular purpose of securing its mulching and phys- ical effect upon the land in the intervals between the regular crops or the normal seasons of tillage. A sowed crop in the orchard may be valuable in two ways: by affording a cover to the land, and by improving the soil when it is plowed in. As a cover, it may keep down weeds, and protect the land from injurious effects of frost. As a green manure, it may add fiber to the soil, and thus augment its power of holding fertility and moisture, and it may add directly to the fertility of the land. This late crop catches and holds the leaching nitrates which the tree -roots utilize earljer in the season. Taken as a whole, the cover crop may be said to improve the soil in eight ways: I. It directly improves the physical condition of the land : Prevents hard soils from cementing or pud- dling ; Holds the rains and snows until they have time to soak away into the land ; Dries out the soil in spring, making early. tillage possible ; Sometimes serves as a protection from frost. Term first used in this connection in Bull. 61, Cornell Exp. Sta. 333 (Dec. 1893). Cover Crops and Moisture. 185 II. It improves the chemical conditions of the soil: Catches and holds some of the leaching ni- trates ; Adds humus; Renders plant -foods available; Appropriates nitrogen, if it is leguminous. As a rule, crops grown for cover alone should be sown not earlier than midsummer. The most thorough tillage can then be given early in the sea- son, and the benefits of the cover can be secured for the early fall and winter. It is generally advis- able to grow a crop which answers for both a cover and green manure, although it is easily possible to make the soil too nitrogenous for some fruits by the extravagant use of such fertilizers. It will also be observed, from the above enumeration of the bene- fits arising from- cover crops, that crops which are killed by the winter may still be exceedingly use; ful. The reader must also be reminded, in passing, that much of the value of the cover crop depends upon its being plowed under very early in spring, as explained in the last chapter. There is much confusion in the popular mind concerning the relation of cover crops to moisture. Some contend that any crop which shades the ground will ke.ep the surface moist and conserve moisture, whilst others, knowing that all plants exhale water, consider that any crop tends to make the land dry. Both these opinions are partly correct. A crop which occupies the soil the entire season, and which does not allow of cultivation, will make the land 186 The Principles of Fruit-growing. dry, whilst one sowed late in the season upon land which has been thoroughly tilled during May, June and July, does not seriously rob the soil of mois- ture. At all events, there need be no fear of dry- ing out the soil by sowing a late crop, for the serious injury of drought is usually effected before such crops are established, and rainfall is then becom- ing abundant ; and the tree needs to be checked, rather than stimulated, at this season, by the trans- fer of the nitrates and moisture to other plants. The most marked way in which such crops conserve moisture is by means of the fiber and humus which they impart to the soil when plowed under ; but even this humus cannot compete with cultivation as a retainer of moisture. An experiment at Cornell* illustrates the value of cultivation over a green crop occupying the land the entire season, in a dry year. The orchard is a hard clay,— just the soil which is benefited by the loosening effects of green manures. The orchard was divided into three portions in 1890, a year after the trees were set. One -third has received liberal annual dressings of commercial fertilizers, and has been well tilled ; another third has had no treat- ment except good tillage ; and the remaining third has had liberal applications of potash, and has then been sown early to a nitrogenous (leguminous) green crop. This third portion has simply been plowed *Bull. 72, Cornell Exp. Sta. This experiment has not yet progressed far enough for report upon methods of fertilizing, and is mentioned here only for the purpose of contrasting methods of cultivation. Cover Crops vs. Tillage. 187 and fitted well each spring, and then sown, having received no subsequent tillage. The crops were all plowed under the following spring. The following are the crops : 1890. Mixed beans. Sowed June 16. 1891. Field peas. Sowed June 24. 1892. Vetch. Sowed June 16. 1893. Cow peas. Sowed June 19. 1894. Field peas. Sowed June 14. Here, then, is a chance to compare the effects of tillage with humus in a season of almost unpre- cedented drought. Upon September 1, 1894, the green manured strip was much the driest portion of the orchard. The tree growth in this portion was much less vigorous, and the leaves were perceptibly lighter colored, than on the adjacent plots. Even the unfer- tilized but well tilled tract showed a better foliage. In this green manure portion, leaves on peach trees were then beginning to yellow and fall from the effects of drought, whilst the same rows, when they struck the other plots, showed perfect foliage. In apricots the effects were also marked. Pears and plums also showed the differences. In the cultivated portions one could easily stir up loose earth with the toe of his boot, while in the green manured part one had to dig from six to ten inches in a hard soil before he could find visible moisture. Careful tests showed the same fact. Samples of soil were taken to the depth of one foot on September 1, by means of a soil sampler, eight samples being lifted from representa- tive parts of both the tilled and untilled areas. 188 The Principles of Fruit-growing. Four of these samples were combined into one, and this mixture constituted the complete sample which was used in a test for moisture ; that is, there were two samples of untilled soil and two of tilled soil, but each of these was made up of four other sam- ples selected from various parts of the areas. These samples were carefully weighed, and were then equally fire -dried and weighed again. The loss in weight represents the comparative content of free water in the different samples. The results are as follows : Sample I. Sample II. Moisture in tilled soil, per cent 11.3 12.8 Moisture in untilled soil, per cent 8.7 9.6 In addition to this difference in moisture between the two areas, it should be said that in the tilled land it was distributed to within two inches or less of the surface, while in the untilled land the first few inches was exceedingly dry. In other words, in the tilled land nearly the entire soil was in con- dition to part with its fertility, while in the other the uppermost and richest soil was inactive. All this emphasizes the fact that tillage alone is better than green manuring alone; but the best re- sults would no doubt have been obtained if good till- age had been given for two or three months, and if the green crop had been sown in July or August. In general, this combination is an excellent one for orchards, particularly for such lands as lack nitrogen and vegetable matter, and for those fruits which are benefited by winter protection of the soil. Choice of Cover Crops. 189 The kinds of cover crops. — It will now be asked what is the best plant for cover and green manure. It is hard to tell. Clover is a stand-by, but it often fails to "catch" late in the season, and it should stand on the land an entire season in order to obtain its full value. Upon good and well- tilled lands and in favorable seasons, considerable herbage can be obtained for turning under in the spring if it is sown the preceding August or Sep- tember ; but in general it is unreliable as an annual crop, and is not adapted to fruit lands. It should be said at the outset that the choice of the proper crop for the covering of an orchard is a local matter, the same as the determination of the method of tillage or the kind of fertilizer is. There is also no one cover crop which is best for all purposes and all conditions. The grower must study the condition of his trees and his land, and then judge as best he may what course he shall pur- sue. Nature's cover crops, at least upon farms, are weeds, and these may be useful if allowed to grow in the fall after the tillage is completed. The difficulty is that they cannot always be relied upon to cover the land at the time when they are wanted, most of them do not live through the winter, and they are very likely to become a serious nuisance. It is best, therefore, to substitute some other plant for the weeds. In approaching the question of the choice of cover crops, the grower must remember that there are two great classes in respect to their power to gather nitrogen. The one class is non- 190 The Principles of Fruit-growing. leguminous, comprising those plants which take only such nitrogen as has already been worked over into available form by plants or animals; the other class is the leguminous plants, comprising those which have the power of appropriating and utilizing free nitrogen. For purposes of cover and protection, the non- legu- minous crops may be just as good as the nitrogen- gatherers, and when the fruit plants are growing very vigorously they may be decidedly better than the others because, by not adding nitrogen, they do not over -stimulate the growth. A rotation of cover crops will nearly always be found to be important. It is perfectly possible to put so much nitrogen into the land that the trees or plants grow too vigorously or too late in the season. This may be especially apparent upon peaches, apricots, grapes, and the like. It should also be said that some of the most useful of these cover crops will not thrive upon hard and intractable land, and in such cases a rougher and coarser crop must be used. The golden scale of cover crops for orchards be- gins with rye and ends with crimson clover. Lands which are very sandy and leachy, as well as those which are hard and lumpy, are usually not adapted to the growth of crimson clover, especially in the north. Such lands must be gradually ameliorated by the use of other plants, and, as a rule, the best plant to begin with is rye. This plant thrives upon a great variety of soils, it demands little preparation of the land, the seeds are large and germinate at a low tem- perature, it can be sown late in the season after Kinds of Cover Crops 191 cultivated crops are removed, and it is exceedingly hardy. Rye may be sown upon the very moment of the freezing up of the land, and it will sometimes germinate the following spring. It is ordinarily best, however, to sow it about a month or six weeks before the land is expected to freeze up ; and for the purpose of securing a cover, not less than one and one -half bushels should be sown to the a<3re when orchards are young. When the trees have begun to shade the ground, a less quantity will answer. Another plant which is sometimes used to begin the amelioration of intractable lands is Indian corn, sown broadcast very thickly, six weeks or two months before killing frost. Although it does not stand the winter, it nevertheless affords an excellent cover for the land and supplies besides a large amount of herbage. Buckwheat may be used for the same purpose, sown so late in the season that it will reach its full height but will not go to seed. There is danger, however, of using buckwheat too much, and only an occasional crop of it— if any at all— should be used upon orchards which are growing upon the hard types of lands. Turnips and rape are also to be recommended in certain cases. Turnips sown late in July in the north make a complete cover of the land, and fur- nish so much bulk and moisture as to greatly improve the character of the soil when they are plowed under the following spring. Turnips are especially good to begin the process of improve- 192 The Principles of Fruit-growing. ment upon certain hard lands which are much in- clined to be dry. Oats, wheat, barley, millet, and various other quick -growing crops may be utilized as covers, but they are less adapted to the purpose than those which have been mentioned. In order to impress the different qualities of cover crops upon the mind, it may be well to say that rye and corn, and the like, are to cover crops what pigs and mules are to domestic animals. Amongst the leguminous crops are the various kinds of peas, beans, vetches, and the clovers. If it is desired to grow a leguminous crop upon land which is hard and dry, it will be necessary to choose those with large and quick -germinating seeds, like the beans and the field peas. Common field beans may be sown broadcast late in the season, and if they can have six weeks of uninterrupted growth, will make a good cover before killed by frost. Canada peas are not injured by the early frosts of fall, and therefore may be sown later. At the Cornell Station, peas sown as late as the 20th of September reached a height of about six inches, and were large enough to afford a fairly good cover, if they were sown very thick. But, in gen- eral, in the northern states, it is advisable to sow not later than the last of August or the first of September. The cow pea ( Vigna Sinensis) can often be used to the greatest advantage, especially in the middle and southern states, where the long seasons allow Cow Peas for Cover. 193 it to make a most luxuriant and satisfactory growth. In fact, it is probably destined to fill the office in the southern states that the red clover does in the north, and, if properly used, can, no doubt, be made the means of filling the burned -out soils of the south with fresh life and vigor. It is killed by the earliest frost, and is, therefore, not advisable at the north, unless sown early or upon land which is in good condition, so that it may obtain a quick start. Experiments with this plant have been made at the Cornell Station,* with the following results: "Six- teen varieties were grown at the Station this year [1893] for the purpose of ascertaining which ones will mature in this latitude ; and over half an acre was sown to the Black pea, which Professor Massey, of North Carolina, thought likely to prove the best variety for our purpose. These black peas were obtained of L. R. Wyatt, Raleigh, N. C., and were sown June 20. The land was clay, and variable in contour, comprising two dryish knolls, with a moist vale lying between them. The peas were slow in starting, owing to the hard soil, but they made a fair growth in August and early September. In the vale, the plants grew nearly two feet high and cov- ered the ground well, but on the knolls the soil was not covered. The plants had just begun to flower when they were killed by the first frost. The leaves fell off, and the bare, stiff stems now afford very little protection to the soil. *Bnll. 61. Cornell Exp. Sta., 334. 194 The Principles of Fruit-growing "The varieties of cow peas, grown for the pur- pose of ascertaining the earliness of the various kinds, were sown May 31, in rich garden loam. These peas were obtained from the Experiment Stations of North Carolina, Arkansas and Louisiana. The varieties ripening seeds are ten, as follows: Black, from North Carolina. Black Eye, North Carolina. Blue, Louisiana. California Bird's Eye, Arkansas \DdUchos sesquipedalis) . Clay, North Carolina. Gray Prolific, North Carolina. Large White, Louisiana. Whippoorwill, North Carolina, Arkansas, Louis- iana. Yellow Prolific, North Carolina. Yellow Sugar Chowder, Arkansas. "The varieties which did not mature seeds are the following: Black, from Louisiana. Brown Eye, Arkansas, Clay, Louisiana. Conch, North'Carolina. Indian, Louisiana. King, Louisiana. Lady, Louisiana. Purple Hull, Louisiana. Stewart, North Carolina. "The varieties which seemed best adapted to this Vetch for Cover. 195 latitude were the Black and Whippoorwill. The lat- ter fruited also at Lansing, Michigan, in 1887. It will be seen that there appears to be a difference between samples of the same variety coming from different sources. The Black pea from North Caro- lina seed matured well, but that from Louisiana stock was too late. The same difference occurred in the Clay. This is what might have been ex- pected, and it emphasizes the importance of securing seed from the northernmost station, when choosing stock for growing in the north. On the whole, the Black cow pea seems best adapted to growing in central New York. A small patch of this was sown on a rich, loose soil July 17, and the plants made as heavy growth as those sown upon the clay soil nearly a month earlier. But the cow pea af- fords so much less winter protection to the soil than the vetch, without any counterbalancing ad- vantages, that it can scarcely be recommended for an orchard cover in the north." Upon mellower and moister lands, however, good results have fre- quently been obtained with cow peas in the northern states, and they are growing in favor. The use of the vetch or tare as a cover plant was brought forward by the Cornell Station,* and reported upon in 1892, as follows : "Orchard lands are nearly always benefited by some cover or mulch during a part of the year, especially during fall and winter. One of the values of sod lies in the protection to the soil, but a sod cannot be obtained *Bull. 49, Cornell Exp. Sta., 1882. Principles of Fruit -growing'. Fig. 20. A good stand of vetch, in November. Sown in early July. in a single season. If orchards can be cultivated in spring and early summer, and then protected with some growth which will shade the soil and keep Experiment with the Vetch. 197 it moist during the remainder of the warm weather, and afford some protection from frost during winter, the best results will undoubtedly be obtained, as a rule. This cover crop should also afford fertiliz- ing materials to the soil when turned under, and greatly improve the mechanical character of the soil as well. '' The leguminous plants — those belonging to the clover family — at once suggest themselves, because they are rich in nitrogen, and may therefore serve both as cover and fertilizer. We have tried mixed beans and field peas, but there are objections to both, although either one is probably better than weeds or bare ground. This year we have tried the European vetch or tare (Vicia sativa) , seed of which we ob- tained of J. M. Thorburn & Co., New York. This plant is grown for forage in England. A half bushel of seed was sown June 16 upon five -eighths of an aero of heavy clay loam. It was sown broadcast upon a freshly prepared surface, and well dragged in. The seed could have been sown later with equally as good effect, no doubt, and the cultivation of the orchard could have been continued for ten days or two weeks longer. The young trees of pear, plum and apricot have made an excellent growth this year among the vetch. The vetch started somewhat slowly, and the seeding seemed to have been too thin ; but by the middle of September the ground was covered thickly. Frost came October 1, but the vetch was not injured, and it continued to grow until the middle of th«i month, and remained green still longer. It made a 198 The Principles of Fruit-growing. remarkable cover, growing knee-high in a dense mat, and everywhere completely covering the ground. It began to flower in September, but no seeds ripened except upon a few poor spots. Upon light soils, seeds would probably form freely, but the plant is an annual, and is not likely to become a weed. The roots do not extend deep. With the approach of hard freezing weather, the stalks fell upon the ground, where they now lie like a thin, even cover- ing of old hay. The stems are soft, and can be easily plowed under in spring, and will soon decom- pose ; and they will not keep the soil wet too late in spring, which is an important point upon clay soils." The following year a second report was made upon it: "The vetch is an annual leguminous plant, which continues its growth long after frost, and which mats down with the snow into a perfect, carpet -like covering. In the spring, the vines are so well decayed that the cover can be plowed under easily. The vetch can be sown late in June or earlj- in July in this state, and the plants will cover the ground with a dense tangled mulch two feet deep when winter sets in. Last year (1892), we sowed the vetch June 16. This year we sowed one area June 20, and another June 28. Both made an ideal mulch, and the plants were green and still grow- ing late in November. They produced no seeds, and but very few flowers. About a bushel of seed should be sown to the acre. The seed is large and germinates readily, and is likely to catch at Crimson Clover for Cover. 199 almost any time during the summer. Some idea of the dense growth of the vetch this year may be obtained when I say that one patch overcame and obscured a heavy growth of horse-radish which had been in the ground two years. I am confident that upon fairly good soil, good results can be obtained with vetch sown as late as the middle and possibly the last of July." Crimson or scarlet clover was brought emphati- cally to the fore as a cover plant for orchards by the Delaware Experiment Station* in 1892. It has been the occasion of much speculation and much misunderstanding. Like other novelties, it has been hailed by some as a plant which is bound to revo- lutionize orchard management and to make planta- tions productive; and others, who have failed, have discouraged its use entirely. The fact is, as already pointed out, that crimson clover is only one step or round in the ladder of cover crops, and it is ordi- narily the last and the highest. By this it is meant that it will not thrive upon hard or poorly tilled land. It must be sown in midsummer or a trifle after, when the ground is likely to be dry. The seeds are small and oily, and the grower is very likely to fail in securing a "catch." Upon the better tilled lands, however, crimson clover may be expected to succeed as often as any other plant of its class will. People have also made a mistake in expecting too heavy a growth of herbage in the crimson clover. It is an annual plant, normally completing its entire *Bull. 16, Del. Exp. Sta., March, 1892. 200 The Principles of Fruit-growing. growth in a single season. When sown at midsea- son, therefore, it should not be expected to yield a very heavy crop. If it should arrive at that stage when it nearly or wholly covers the surface of the ground with a thin, close mat, it will have reached its most profitable condition. Neither is it necessary that the plant should stand the winter and grow in the spring. Turnips, maize, vetch, and other tender plants are known to be very useful as orchard cov- Fig. 21. A good stand of crimson clover as it looks before growth has begun in the spring. ers, although they pass the winter in the dead state. If the crimson clover passes the winter and grows in the spring, much will be gained; but if it should not pass the winter, nothing will be lost. In respect to the proper time for sowing crimson clover, it may be said that if it is sown very early in the season (that is, before the first of July), it is likely to be- come too large and ripe, and be killed by the win- ter; if it is sown too late (that is, after the middle Legumes as Fertilizers. 201 of August in the north), it will ordinarily not attain sufficient foothold to be able to withstand the heav- ing by frost. Crimson clover may be sown amongst Indian corn at the last cultivation, but in orchards it is ordinarily sown from the middle of July to the middle of August in the north, upon a well prepared seed-bed, and is then lightly dragged in. In old or- chards, six quarts to the acre is a sufficient amount of seed; in open lands, about eight quarts are re- quired. The following analyses show the fertilizer values of the various leguminous plants here discussed. The vetches and peas were analyzed at the Cornell Station. The analysis of cow peas is taken mostly from Professor Teller's recent studies in Arkansas, those of clovers from reliable sources for comparison: VETCH, KEADY TO BLOOM, ROOTS AND TOl'S.

Having now discussed how, by tillage and cover crops, the land may be made fit for the growing of fruit plants, we come to the question of what plant -foods may be added to the soil. It should first be said that fruit plants use up plant -foods NOTE.

In fact, the depletion of the land by fruit trees is more serious than by annual crops, from, the fact that plant- foods are locked up for many years in the trunks and branches of the trees, whilst a large part of the fertilizing constituents in common crops returns to the soil each year. On Lthe other hand, it should be said that the roots of trees have a larger foraging area than the roots of small crops do. This is well shown in Figs. 17 and 18 (pages 160 and 162). The former shows the roots running far away in the poorly tilled soil in search of food, and the latter shows the home -stay ing roots in the rich soil. Roberts has computed,* from analyses, the values of nitrogen, phosphoric acid and potash taken from an acre by apple trees (the trees thirty -five feet apart) in twenty years, counting in ten crops of fruit : Value. •' Total in fruit for twenty years $147.00 Total in leaves for twenty years 160.51 Total in wood for life of. tree 70.00 Grand total $377.51 "The value of nitrogen, etc., in any given case is so indefinite and variable that stress should not be laid on values as given above, but on the total amounts of plant -food used by the orchard. *Bull. 103, Cornell Eip. Station. 204 The Principles of Fruit-growing. "The total amount of nitrogen, exclusive of that used in the growth of the trees, is 1,336.8 pounds, of phosphoric acid 310 pounds, and of potash 1,895.4 pounds. To restore the potash alone, as above, and that used by the growth of the tree, it would re- quire 21.69 tons of high-grade ashes containing 5 per cent of potash. To restore the nitrogen as above, would require 16.19 tons per acre of a com- mercial fertilizer containing 5 per cent of nitrogen. "How much of this plant-food is usually fur- nished to the orchard by leguminous plants and by feeding supplementary foods to animals which graze upon it, and how much by the fallen leaves and apples which are not blown or carried off, cannot be told. "While some of the computations and conclusions are based on estimates, yet it is believed that the tables represent average conditions, and need only the good judgment of the observant reader to make them apply to his individual case with such degree of accuracy as to give valuable aid in the care and feeding of orchards. "Many old orchards have not only been making these large demands on the soil for the last twenty years, but in many instances the land has been used for the production of hay or grain, or more fre- quently for the growing of lambs or pigs, with little or no supplementary food. The grazing of orchards, especially with growing animals without extra food, is as certain to deplete the land as grain raising, though the soil robbery is not so rapid. Plant -food Consumed by Apples. 205 "These investigations, when considered in all their hearings, lead one to wonder not why old orchards are failing, but why they have not ceased to pro- duce merchantable fruit long since." Another calculation by the same investigator shows the amount of plant -food which may be ex- pected to be carried away in the fruit, and blown off in the leaves (not computing the amount in the wood), for the period between the ages of 13 and .'53 years of apple trees : Apples.

He also "shows that an average crop of apples removes in round numbers eleven pounds of nitro- gen, nearly one pound of phosphoric acid and six- teen pounds of potash, and that the leaves of a tree large enough to produce the apples would con- tain ten pounds of nitrogen, nearly three pounds of phosphoric acid and ten pounds of potash, or a total 206 The Principles of Fruit-growing. of twenty -one pounds nitrogen, three pounds phos- phoric acid, twenty -six pounds potash." "As a clearer comprehension is had by comparing unfamiliar things with familiar things, a table follows which gives in brief the soil exhaustion which is likely to occur from a continuous twenty -year wheat production. Here, again, an average yield has been assumed which, while approximately correct for New York, may be wide of the mark in some states where the average yield of wheat falls to eight or ten bush- els per acre. "The following tables show the amounts and values of the fertilizing ingredients removed by wheat (grain and straw) in twenty years' continuous crop- ping, assuming an average yield of fifteen bushels per acre and seven pounds of straw to three pounds of grain : "COMPOSITION OF WHEAT AND STRAW.

No one would think for a moment of trying to raise wheat, even on our best New York land, for twenty consecutive years, even though the soil was fitted in the best possible manner yearly." Respecting the need of fertilizers for orchards, Voorhees writes as follows:* "It is argued by many, and sometimes by those who should know better, that fruit-growing is quite similar to growing trees; that the question of soil exhaustion is not a matter of very great importance, provided the soil is well culti- vated, and that all soils contain sufficient quantities of the food elements to insure the relatively small available supply required from year to year. "It is admitted that on soils of good mechanical condition, well drained and cultivated, which are naturally adapted for fruit as well as other crops, be- cause well supplied with the essential constituents — nitrogen, phosphoric acid, potash, and lime — the exhaustion arising from the continuous removal of crops will not become apparent for a long time, but it should be emphasized that it is only upon soils which possess these characteristics that the growth of fruit, even poor fruit, can be continued for any considerable period without the application of manures." "It is obvious that such specific results as have been obtained concerning the needs of general farm *E. B. Voorhees, "Manuring Orchards", before Mass. Hort. Soc. Mar. 28 MM 208 The Principles of Fruif-r/ rowing. crops, as grain and grass, for specific plant -food ele- ments, cannot be applied with any degree of accuracy to fruit crops, particularly the larger fruits, as pears, apples, peaches, grapes, and plums, because these dif- fer from the cereals, grasses, and vegetables, first, in their habits of growth, second, in the character of the produce, and third, in their relation to soil ex- haustion. "In the first place, farm crops, as a rule, require but one year for the entire processes of vegetation and maturation. For fruit crops, with but few ex eeptions, the purely vegetative processes continue for at least three years, and with many kinds much longer, while after the fruit -bearing period begins the vegetative processes do not cease, but are coincident with the growth and ripening of the fruit. In the second place, the product of the harvest, namely, the fruit, differs very materially in its character from that of ordinar}- farm crops, which mature their fruit and die in one season, because a whole season is re- quired for its growth and development; that is, it is necessary that there shall be a constant transfer of the nutritive juices from the tree to the fruit throughout the entire growing season, while the growth for each succeeding year of both tree and fruit is dependent upon the nutrition acquired and stored up in buds and branches, as well as upon that which may be derived directly from the soil. In the third place, the relation of fruit-growing to soil ex- haustion is very different from that in general -crop farming, because in orchards there is an annual de Needs of Fruit Trees. 209 mand for specific kinds and proportions of soil con- stituents; it is really a continuous cropping of the same kind; there is no opportunity, as in the case of ordinary farm crops, to correct the tendency to exhaustion by a frequent change of crops, or the frequent growth of those which require different kinds and amounts of plant -food constituents. "In studying methods of manuring orchards, how- ever, it must be admitted that the general princi- ples of manuring which apply to fruits apply quite as well to farm crops; that is, the essential con- stituents of manures must be the same. A fruit tree will not make normal growth in a soil destitute of nitrogen. That nitrogen encourages leaf-growth is a recognized fact, and, since trees grow by means of both leaf and root, its presence is required in the soil in order to promote the growth and extend the life of the tree. It is very evident, too, that pot- ash is an essential constituent in the growth of fruits, not only because it constitutes a large pro- portion of the ash of the wood of the apple, pear, cherry, and plum, and more than 50 per cent of the ash of fruit, but because it forms the base of the well-known fruit acids ; and in order to nourish a tree properly, as well as to insure proper ripen- ing, phosphoric acid is also very essential, though it is apparent from such investigations as have been made that this constituent is relatively of less importance than for the cereals. "It is also a matter of common observation that, in the production of stone-fruits particularly, lime 210 The Principles of Fruit-growing. is an important constituent. Its function seems to be to strengthen the stems and woody portion of the tree, to shorten the period of growth, and to hasten the time of ripening. Fruit trees growing on soils rich in lime show a stocky, steady, vigorous growth, and the fruit ripens well, while those on soils which contain but little lime, particularly the clays, appear to have an extended period of growth, the result of which is, that the wood does not mature and the fruit does not ripen properly." Voorhees also reports* an experiment in the fer- tilizing of peaches, showing large gains in crop from the separate use of stable manure and fertilizer. "It is interesting to observe," he writes — "and it is a point of great importance — the effect of an abundance of food in overcoming unfavorable weather or seasonal conditions. The year 1889 was extremely unfavorable, and the crop throughout the state [New Jersey] was small. In this experiment the unman ured plot yielded at the rate of ten and nine -tenths bas- kets per acre, while the manured and fertilized plots both showed a yield exceeding one hundred and fifty baskets per acre. The manure strengthened and stimulated the trees, and enabled them successfully to resist such conditions as were fatal to the crop on the unmanured land. This point is one that is seldom considered in calculating the advantages to be derived from proper manuring, though it is of extreme value, since the expenses of cultivation, trim- *See, also, Repts. N. J. Exp. Sta., 1884-1894. Stable Manures for Fruits. 211 ming, and interest on investment are quite as great in one ease as in the other." Stable manure. — The kinds of fertilizing applica- tions are of two types, stable manures and concen- trated or commercial plant -foods. The stable manures exercise a most important effect upon the physical features of the soil, and, in fact, this is often their greatest value. In this respect, stable manures may answer much the same purpose as green or cover crops, particularly if they are applied in fall or early winter. When manure is not sufficient to cover the entire plantation, it should be applied to the hardest and driest spots only, and these spots should be observed and noted the previous season. Lands which are so hard or dry that even rye will not catch, may be got under way for the cover crops by liberal applications of barn manures. Rota- tion in the use of fertilizers may be found to be as useful as it is in the case of cover crops. A soil which has had a liberal application of stable manure one year, may profit more by some chemical fertilizer the next year. In orchards which are thoroughly tilled, the use of barn manures should sometimes be discouraged, for the chief element of fertility in them — if they are not leached— is usually nitrogen. This advice is particularly applicable to vineyards, and all other fruits which run very strongly to wood. In such cases, it is better economy to apply the manures to the annual crops of the farm. The old, neglected u|)ple orchards of the country, however, may receive 212 The Principles of Fruit-growing. barn manures with safety; yet, even here it is a question if economy would not dictate tillage and late green manures to supply the nitrogen, except, perhaps, for a season or two when an attempt is making to rejuvenate an orchard. Mulching a sod orchard with manure often gives fairly good results in cases in which the land cannot be cultivated ; but better results in the way of fertilizing and in freedom from weeds and insects can be obtained by pastur- ing closely with sheep or swine. Chemical fertilizers. — Nitrogen, potassium and phosphorus are the elements which need to be ap- plied to orchard lands ; and to these should some- times be added lime, mostly for its secondary effects upon the soil. Nitrogen is particularly efficacious in promoting growth. "The general tendency of nitrogenous ma- nures is toward the excessive production of wood and foliage," writes E. F. Smith, after having made many explicit experiments upon peach trees.* In fact, the amount of growth and the color of foliage are reliable guides for the application of nitrogen. When mature or bearing trees make a foot or more of growth upon all shoots, and when the leaves are of good size and dark color, the orchari' probably has enough nitrogen. A free application of nitrogen to such orchards might do more harm than good, in promoting growth at the expense of fruit, or, in the case of some stone fruits, in pro- *Bull. 9, Section of Veg. Path., Botanical Div. U. S. Dept. Ap-.. 142. Nitrogen for Orchards. 213 ducing a poorly matured growth, which will be likely to suffer in winter. Orchards are grown for fruit, not for forestry purposes. In general, it is better to supply nitrogen by good cultivation — which assists nitrification — and an occasional green -manure crop, than by the application of nitrogenous fertilizers. If the orchard is not growing, and is yellowish in foliage, good cultivation— begun early and repeated very frequently — in connection with the use of pot- ash, phosphoric acid and green manures, will com- monly correct it. It is probable that lack of moisture is quite as much the cause of the weak- ness as lack of nitrogen, particularly if the orchard has been in sod. Now and then a tree will be found which fails to respond to ordinary treatment. If the tree is healthy — that is, not attacked by dis- ease or borers — it may sometimes be brought into a vigorous condition by applying to it a light dressing of nitrate of soda ; but this treatment need seldom be applied to an entire orchard which has been well hnmllcd. An experiment made by the Cornell Station (Bul- letin No. 153) gave very decided results from the use of nitrate of soda alone. An apple orchard about twenty-five years old and unproductive, standing upon a rather hard and dryish light clay loam, was plowed in the fall of 1894, and certain trees were given an application of ten pounds of nitrate of soda. Contiguous rows received heavy applications of sulfate of potash and muriate of potash. All materials were applied August 11, 1894. The or- 214 The Principles of Fruit-growing. chard was plowed again in the fall of 1895, and a third time in the spring of 1896. None of the dressings showed any effect in 1895, but in 1896 the trees which had received the nitrate of soda were very remarkably superior to those which had received the other treatments and to those which had received none. They had very much heavier and darker green foliage, so that they could be readily distinguished many rods away, and they had a heavier load of fruit, which was larger and finer than that upon the other trees. This heavier crop was probably not due to more profuse blossoming, but to a less dropping of young apples. In 1897, the trees still showed the effect of the nitrogen. In 1898, all effects were lost, and the trees and fruits could not be distinguished from those which were un- treated. Nitrogen -fertilizing often exerts a decided influ- ence in delaying the maturity of fruit, and it is worth 'while to consider the application of such fertil- izers to winter apples which tend to ripen too early. These fertilizers also tend to the production of low colors in fruit. Lodeman found,* as the result of experiment, that "the apples produced upon the plot which was, in all probability, the richest in nitrogen, were late, and they were also poorly colored." Potash is generally the most important element to be applied directly to orchards, particularly after * Rural New-Yorker, Jan. 2, 1897, 2. Potash for Fruits. "215 the trees have reached bearing age. The store of available potash in the soil is much increased by the thorough tillage which has already been recom- mended, but in bearing orchards it should also be supplied every year in some commercial form. One of the best sources of potash for orchards is wood ashes, but this material is so often weakened by leaching that it cannot be confidently recommended. A good sample of unleached hard wood ashes should contain from 5 to 9 per cent of potash, but some of the commercial article does not analyze above 2 to 3 per cent. Potash in this form has a trade value of 4% cents per pound. To this value of wood ashes should also be added 2 per cent or less of phosphoric acid, now worth 6 cents a pound. Forty to fifty bushels to the acre is considered to be a good dressing of wood ashes, if it has been kept dry. Muriate of potash is perhaps the best and most reliable form in which to secure potash at the present time for fruits. Commercial samples gener- ally contain from 80 to 85 per cent of muriate of potash, or about 50 per cent of actual potash. Kainit is an impure muriate of potash, containing about 12 to 15 per cent of potash. An apple or- chard in full bearing and upon loose soil may receive as high as one thousand pounds of muriate of potash per acre, but a normal and economical application is from one hundred and fifty to three hundred pounds, if applied every year. Sulfate of potash is also thought to be a good form in which 216 The Principles of Fruit-growing. to buy potash. The commercial article analyzes 50 per cent or less of actual potash. Sylvinit is a lower grade of potassium fertilizer. Its value— like that of other materials mentioned — should be reck- oned upon the amount of potash present. Phosphoric acid may be obtained in the form of a high-grade plain superphosphate (like dissolved South Carolina rock), in bone compounds, and Thomas slag. The plain superphosphate contains about 16 or 18 per cent of phosphoric acid, and two hun- dred to five hundred pounds per acre is a liberal and very useful dressing for bearing orchards. The bone fertilizers are always valuable. Those which are untreated give up their phosphoric acid slowly, unless they are very finely ground. Dissolved bone gives more immediate results. Thomas or basic slag, which is yet less known to farmers in this country, has given good results in many tests, but it parts with its fertility very slowly. It is yet too early to recommend this material for orchards with full confidence. In general, phosphoric acid is probably less im- portant in fruit plantations than potash, although this order is reversed in general farming. Potash should undoubtedly be the leading factor in orchard fertilizers, and nitrogen may be obtained largely, or even wholly, in some cases, by means of tillage and green crops. It will then be seen that the use of combined or " complete " commercial fertilizers may not be economical. The best results are to be ex- pected when the fruit-grower observes closely the Fertilizing Orchards. 217 behavior of his trees and then applies such materials as the plants appear to need. Any of the mate- rials mentioned in the foregoing remarks may be mixed together, so that the phosphorus and potas- sium can be applied at the same sowing. It should be said, however, that if wood ashes is mixed with a nitrogenous fertilizer, some loss of nitrogen may ensue, unless the material is used at once.* Voorhees givest the following "practical sugges- tions" for the fertilizing of orchards: "A system of manuring for cultivated orchards, based upon the limited data at ou^ disposal, may be outlined as follows : "To provide vegetable matter and to improve th<> physical quality of poor soils, apply yard manure once in four years, in fall or winter, at the rate of from five to ten tons per acre. To aid in the decomposition of vegetable matter, and to insure a * To answer inquiries concerning the prices of fertilizing materials, it may l>e said that muriate of potash costs $40 and upwards per ton, sulfate about $48, dissolved boneblack about $24, ground bone about $:«), kainit about $13, and nitrate of soda 2% cents per pound. These prices vary, of course, with the composition or mechanical condition of the materials. The average com- position of unleached ashes in the market is about as follows : Potash, 5.2.") per cent ; phosphoric acid, 1.70 per cent ; lime, 34 per cent ; magnesia, 3.40 per cent. The average composition of kainit is 13.54 per cent potash, 1.13 per cent lime. The composition of sylvinit (which is said to be known as sulfate of potash in some quarters) is about 16 per cent of potash, in the form of both muriate and sulfate, mostly the former. The fact that the soil itself is the greatest storehouse of plant-food is shown by the follow- ing average of thirty-five analyses of the total content of the first eight inches of surface soils, per acre : 3,521 pounds of nitrogen, 4,400 pounds of phosphoric acid, 19,836 pounds of potash. Much of this is unavailable, but the good tillage and cover cropping which have been recommended tend to unlock it. t E. B. Voorhees, address before Mass. Hort. Soc. Mar. 28, 1896. 218 The Principles of Fruit-growing. sufficiency of lime as plant -food, apply lime at the rate of twenty -five bushels per acre once in five years. To provide, in addition, an abundance of all forms of available plant -food at the times needed for the development of the tree and fruit, apply annually chemical fertilizers in the following pro- portions : "Nitrate of soda 100 Ibs. South Carolina rock superphosphate 100 " Ground bone 200 " Muriate of potash 200 " "The amounts to be applied depend upon the character of the soils, as previously outlined, the kind of fruit, and the age and vigor of the tree ; these given perhaps mark the minimum. "In a number of best orchards the quantities applied are very much larger than is here indicated, and the larger application is believed by the grow- ers to be proportionately profitable. "By the recent introduction of crimson clover, we have a plant admirably adapted to supply cheaply nitrogenous vegetable matter for orchards, and its growth is to be recommended wherever the plant can be successfully grown, instead of the use of barnyard manure, particularly upon the poorest soils, until they are abundantly supplied with vegetable matter. The clover should be plowed down early in the season, in order not to retard the spring growth of the trees. Where the conditions are favorable for the growth of clover, the application of nitrate of soda may be omitted." What Treatment is Needed. 219 Summary statement.— The fruit-grower will no doubt desire to ask how he is to tell just what kind and what quantity of fertilizers to apply to his land. This is one of those questions which no person can answer for him. Having studied the matter carefully, and having observed his plantation from day to day and year to year, he should be able to discover about the treatment which it needs. As a general statement, it may be said that the fruit plantation which is giving satisfactory results is receiving the very treatment which it needs ; but when it is giving unsatisfactory yields, some change in the management should be made. An orchard which is in sod and not doing well should certainly be plowed and tilled. One which is tilled and is not doing well may be benefited by seeding down, or it may not. If the growth is strong and rapid, and the trees or vines seem to be going to wood at the expense of fruit, then some check may be necessary. This check may be given by seeding down for a time, by giving somewhat less thorough or prolonged cultivation, or by the use of rather more mineral fertilizers and less nitrogenous ones. In all cases in which the growth is not sufficient and the leaves are yellow and drop early, it is probable that either more nitrogen or more moisture, or both, is needed. As a general principle, it may be said that nitrogen can be had in sufficient amount by thorough and judicious tillage, by the use of leguminous cover crops, and by stable manure. In some cases, how- ever, quicker and cheaper results may be had by 220 The Principles of Fruit-growing. the direct addition of nitrogenous materials, like nitrate of soda, sulfate of ammonia, or some of the animal compounds. The grower should also remember that the plants need all the elements of plant growth, and not one of them alone. For example, a heavy application of nitrogen upon soil which is deficient in potash and phosphoric acid cannot be expected to give useful results. In the same way, the application of pot- ash to soil which is very poor in nitrogen or phos- phoric acid would be comparatively useless. The heavy loamy or clay lands nearly always contain an abundance of potash and phosphoric acid in a more or less unavailable condition, and much of these materials can be liberated to the plant by care- ful tillage and the incorporation of humus. How- ever, it is nearly always advisable, in orchards which are bearing, to add these materials in the shape of manures or concentrated fertilizers. The quickest results following the use of fertilizers will be seen upon the sandier lands. Two or three years often elapse after the application of chemical fertilizers to heavy lands before any decided results are observed. In other words, clay lands ordinarily show quicker results from tillage than they do from the application of fertilizers. The farmer should bear in mind that he should never rely exclusively upon chemical plant -foods, because they contain no humus, and the soil is apt to become hard and life- less. They should be used in judicious rotation, or in connection with cover crops, or stable manures. Humus Improves the Land. 221 or applications of muck or some other organic dress- ings. It is not necessary that the chemical fertil- izers should be mixed before application ; in fact, upon lands of varying soil and conformation, it ift ordinarily better to apply the different ingredients separately, because different parts of the plantation may need different amounts of the various materials. The low lands will ordinarily need less of the nitro- gen and perhaps more of the potash and phosphoric- acid. In general, it is advisable to buy the plant- foods separately, as advised in the preceding pages. Farmers do not appreciate the importance of humus as an ameliorator of land. In farm lands, it is usually supplied in form of green crops, stubble or sward, and barn manures. When humus is ab- sent, sandy soils become too loose and leachy and hot, and clay soils bake and become lumpy. The different physical characteristics of clay lumps and mellow soils are largely due to the greater amount of humus in the good soil, and yet we have seen that the chemist may pronounce the cloddy soil richer in native plant -food. If the farmer has much of this hard, unproductive land, what is to be done with it ? To cover it with commercial fer- tilizer would be of little benefit. It must first be put in fit condition for the growing of crops. A crop of clover plowed under would quickly improve it, but if tne land is planted to orchard he does not care to seed it down. The next recourse is stable manure. Of this, perhaps enough can be had to cover the hardest soots. For the rest, 222 The Principles of Fruit-growing. catch or cover crops must be used. Following the early tillage, he can sow rye, and plow it under very early in the spring. Now and then he can use a fall crop of sowed corn or oats, or something of the kind. After a time, he may be able to get the land in such condition of tilth as to secure an occasional stand of crimson clover. This practice, continued judiciously for a few years, ought to radi- cally change the character of the land ; but all this will be of little avail unless the plowing and cul- tivation can also be done in a timely and intelli- gent way. All this will take time and patience. He may wish that there were some short-cut and lazy way of improving this land by making some appli- cation of fertilizer to it, but there is not. The most he can do is to slowly bring it into such condition that it will pay to put concentrated fertiliz- ers on it. In short, the first step in the enrichment of unproductive land is to improve its physical con- dition by means of careful and thorough tillage, by the addition of humus, and perhaps by underdrainage. It must first be put in such condition that plants can grow in it. After that, the addition of chemi- cal fertilizers may pay by giving additional or re- dundant growth. All this means that no amount of penance in the way of applications to the land can ever atone for the sins of poor tillage ; or, farm- ing cannot be done by recipe. The gist of the whole matter respecting the use of fertilizers is that the grower should experiment with his plantation, adding a little more of this Summary Conclusions. 223 and a little more of that as he thinks the different trees or the different types of land may need. There is no other way of arriving at this local knowledge except by trying for oneself. If one is observant of the conditions, he will after a time come to have an intuitive sense of what the land prob- ably needs, but he may not be able to tell just why it needs it. In most matters of handicraft in agriculture, the skilled man develops methods and results almost unconsciously. These methods are really founded upon close observation and truthful inductions, but the person can rarely ever impart this particular information to his neighbor. The only general statement, perhaps, which can be made, is that liberal applications of potash and phos- phoric acid should nearly always be made to bearing fruit plants, if the grower desires the best results; and he may be able to supply his nitrogen more cheaply by cover crops and tillage than by buying chemicals, CHAPTER V. THE PLANTING OF FRUIT GROUNDS. THE subjects which one naturally considers when starting out to begin the planting of a fruit area fall into four categories, — the choice of the varie- ties, the selection of the trees or plants, the actual setting of the stock, and the laying out of the fruit plantation. These matters may now be con- sidered. THE CHOICE OF VARIETIES. The most personal matter connected with the making of a fruit farm is the subject of choice of varieties. This is the one subject upon which most questions are asked, and it is also the one upon which the least specific and dogmatic advice can be given. The choice of varieties depends primarily upon the personal preferences of the grower, upon the purpose for which the fruit is to be grown, and upon the locality. Without knowing these three elements, it is impossible for any person to give satisfactory advice as to varieties. The grower who has no personal preferences for varieties is one who has not yet mastered the first essential to (224) Choosing the Varieties. 225 successful fruit-growing, — the obtainment of a spe- cific ideal. In the greater number of eases it is easy to answer questions .as to what varieties to plant by asking the questioner what he wants to plant. He will commonly answer his own question fully. The intelligent question about varieties is that which asks for specific information ; as, for example : What is the best red fall apple for southern Ohio ? What is the earliest raspberry ? What is the hardi- est apricot? What is the largest plum? What is the best strawberry for canning ? Such questions as these indicate that the questioner has classified his own ideas, and that he is driving straight to the point for information ; and they are usually capable of rather definite answer. When a man asks, "What variety of fruit shall I plant?" no one should attempt to answer. The writer has long since come to the practice of refusing to recom- mend specific varieties to individual persons. He prefers to name those varieties which he thinks might please himself for the purpose or place named, or to give lists of the kinds most likely to meet the requirements ; but the grower must choose for himself. There are a few general rules or precepts which may be stated to aid the intending fruit -planter in the choice of varieties:* 1. So far as possible, follow your own personal preferences,— the type of fruits which you love best *The whole question of the running out of varieties is discussed in «Th« Survival of the Unlike." 226 The Principles of Fruit-growing. or take most interest in. These are the ones with which you will most likely succeed. 2. Obtain a clear and specific ideal of the pur- pose for which the fruit is to be grown, — whether for dessert, for canning, for a local market, for ex- port, for evaporating, and the like. Then choose the varieties which are best suited to meet these ideals. 3. Do not covet a variety simply because it is eminently successful in another region. Varieties have distinct adaptations to geographical areas. If a given variety is a universal success in the plains regions, the probabilities are that it will not thrive equally well in New England. The farmers of the east have learned that they cannot compete with those of the west in the growing of wheat, but they have not yet learned that one region may not be able to compete with another in some particular variety _ of fruit, even though the variety thrive well in both. It is a question if the northeastern states can compete with the mid -western states in the growing of the Ben Davis apple. The south and mid -south are being planted extensively to the Kieffer pear, largely because it thrives better over a large area than most other varieties. It is doubt- ful, then, if it is wise to plant it extensively in the north, where other pears will thrive which do not succeed in the Kieffer region. Diversification must come to be more and more important in fruit-growing; and any region should grow that type of fruit most freely which other regions can- not grow so well. Choosing the Varieties. 227 4. Choose with reference to the local environment One must consider t,l?e adaptation of the variety to his particular climate, to the probable length of his season, to his distance from market, and to his system of husbandry. The adaptation of varieties to soils is an important consideration, and one which demands closer attention as cultivation becomes more intense and perfect. As a rule, the finer the variety in quality, the less able it is to thrive equally well under diverse methods of treatment. It- is partly for this reason that des- sert fruits are commonly regarded as unreliable and difficult to grow. Fig. 22. strawberry One can scarcely hope for success in "°e™esr moA* the best horticulture unless he gives particular study to the adaptations of species and varieties to soils. 5. Choose with reference to inter- pollination. It is known that some varieties of fruits are self -sterile, — that is, they are not iruitful when planted alone. This sterility may be due, as in the case of the straw- berry, to imperfect (or unisexual) flowers, or, more commonly, to pollen which is impotent upon the pistils of the same flower.* This infertility or self- sterility is largely a varietal characteristic, yet it is no doubt greatly modified by seasonal and enviroii- *For a discussion of the philosophy of this self -sterility, see the essay oil "Sex in Fruits," in "Survival of the Unlike," p. 347. 228 The Principles of Fruit-growing. mental conditions. It is probable that varieties may sometimes be self -fertile and at other times self- sterile. The strawoerry flowers in Fig. 22 show the marked influence upon pollen -bearing which is ex- erted by different conditions. The flowers are of the same variety, and were grown under glass. The lower one shows the small development of stamens in a long cloudy spell, and the upper one shows the profusion of stamens which appeared in other flowers after two or three days of sunshine. It is probable that pollen is more profuse and more potent in some years than in others. There is very little positive knowledge concerning the inter -pollination of fruits, and no subject con- nected with pomology is in greater need of study. We chiefly know that the most productive orchards are usually those of many varieties, and that some varieties sometimes refuse to fertilize themselves. The most positive knowledge respecting the impotency of pollen amongst our common fruits is in connection with the plums of the Wild Goose type. The safest practice, therefore, is to plant no more than two or three rows of any one variety together of fruits in which self -sterility is a frequent characteristic (pears, plums, apples). The chief point to be observed in se- lecting the varieties is that they shall bloom together. All pears and apples, and nearly or quite all plums, seem to be inter-fertile when they bloom simultaneously. The following lists of self -sterile and self -fertile fruits are summaries of our present knowledge upon the subject: Impotent Fruits. 229 Pears — Varieties more or less self-stertile. — Angou- leme, Anjou, Bartlett, Boussock, Clairgeau, Clapp, Columbia, De la Chene, Doyenne Sieulle, Easter, Gan- sel's Bergamotte, Gray Doyenne, Ho well, Idaho, Jones, Kieffer, Lawrence, Louise Bonne, Mount Vernon, Pound, Sheldon, Souvenir do Congres, Superfin, Colonel Wilder, Winter Nelis. Varieties generally self-fertile. — Bosc, Brockworth, Buffum, Diel, Doyenne d'Alenc.on, Flemish Beauty, Heathcote, Le Coute, Manning Elizabeth, Seckel, Tyson, White Doyenne. Apples— Varieties more or less self-stertile. — Bellfleur, Chenango (Strawberry), Graveustein, King, Northern Spy, Norton Melon, Primate, Rambo, Red Astrachan, Roxbury Russet, Spitzenburg, Talman Sweet, Willow Twig, Winesap. Varieties mostly self -fertile. — Baldwin, Ben Davis, Codlin, Fallawater, Greening, Oldenburg, Rail's Janet, Red Astrachan, Smith Cider. Plums — Varieties more or less self -sterile. — Coe Golden Drop, French Prune, Italian Prune, Marianna, Miner, Ogon, Peach, Satsuma, Wild Goose and many other native plums. Varieties mostly self -fertile. — Burbauk, Bradshaw, De Soto, Green Gage, Lombard, Robinson, Damsons. Strawberries often lack stamens altogether, whilst others, like Crescent, have so few and so poor stamens that they are practically self-sterile. Ordi- narily, there should be a row of a perfect -flowered variety for every two rows of a pistillate or infer- tile variety. 230 The Principles of Fruit-growing.

THE SELECTION OF THE PLANTS, It is first of all necessary, in selecting the plants for fruit grounds, to determine what first-class stock is. "The nurserymen contends that he grows the *For recent notes, see Beach, Bull. 169, N. Y. Exp. Sta. tNotes upon the uses of variety tests by experiment stations will be found in « Survival of the Imlike," pp. 171 and 370, jThe Methods of propagating are fully set forth in "The Nursery- Book." First -class Stock. 231 varieties which the planters want — those for which there is a demand. As a matter of fact, he largely forces the demand by magnifying the value of those varieties which are good growers in the nursery. The nurseryman's business ends with the growing of the young tree, and the tree which makes the straightest, most rapid and cleanest growth is the one which finds the readiest sale. Now, it by no means follows that the variety which is the cheapest and best for the nurseryman to grow is the best for the fruit-grower. Probably every apple -grower is now ready to admit that the Baldwin has been too much planted, whilst Canada Red and various other varie- ties which are poor growers in the nursery row have been too little planted. "The blame for this condition of things does not rest wholly with the nurseryman, although it is partly his fault. The original difficulty lies in the fact, it seems to me, that our conception, and con- sequently our definition, of what constitutes a first- class tree is at variance with the truth. We con- ceive a first-class nursery tree to be one which grows straight and smooth, tall and stocky, whilst we know that very many — perhaps half— the varieties of apples and pears and plums will not grow that way. In order to make our conception true, we grow those varieties which will satisfy the definition, and, as a result, there is a constant tendency to eliminate from our lists some of the best and most profitable varieties. "All this could be remedied if people were to be 232 The Principles of Fruit-growing. taught that varieties of fruit trees may be just as different and distinct in habit of growth as they are in kind of fruit, and that a first-class tree is a well- grown specimen which has the characteristics of the variety. It seems to me that it is time for nursery- men to begin to enforce this conception upon the public. Why may not a catalogue explain that a tree may be first-class and yet be crooked and gnarly ? Why not place the emphasis upon health and vigor, and not upon mere shape and comeli- ness ? And why may not a nurseryman give a list of those varieties which are comely growers, and another list of those which are wayward growers?"* It is generally best to buy first-class trees, — those which are of medium size for their age, shapely in body and head, stocky, with straight, clean trunks and abundant roots, which are not stunted, and are free of borers and other injuries, and, in the case of budded trees, those in which the union is very near the ground ; and the tree should show the natural characteristics of the va- riety. In dwarf pears, especially, it is important that the stock, to be first-class, shall be budded very low. It is often thought that large size is of itself a great merit in a nursery tree, but this is an error. Vigor, cleanness, stockiness, firm, hard growth, are much more important than bigness. The toughest and best trees are usually those of medium size. The very small extra expense which *«The Survival of the Unlike," p. 246. Age of Plants for Setting. 233 one incurs in buying the best trees is a good in- vestment. In an acre of apple trees, the difference in cost of first-class over second-class trees will not be more than a dollar or two, but the differ- ence in results is often great. The age at which plants should be bought must be governed by circumstances and by variety. There is a general tendency to buy trees too old rather than too young. When varieties are new and scarce, it may be economy to buy young stock. Some of the freer -growing apples and pears are large enough when two years old, if grown from buds ; but these fruits are usually set at three years from the bud or graft. Dwarf pears may be set at two or three years, preferably at the former age. Quinces are set at two and three years. Peaches are set at one year from the bud. Strawber- ries are set only from new plants (that is, those which have not borne) ; gooseberries and currants prefera- bly from two-year stock, and raspberries and black- berries from stock not more than one season old. Dwarfs vs. standards.— Fruit-growers are always asking whether standard or. dwarf trees are the better to plant, but the question is a personal one, and cannot be answered for another any more than the question can as to whether peaches are more desirable than plums. Dwarf apples and dwarf pears are of a different type of fruit-grow- ing from the standards, and the intending grower must weigh the evidence for and against as best he can. As a general thing, the standards are the 234 The Principles of Fruit-growing. safer and more reliable ; but persons who are will- ing and competent to give the extra care which the dwarfs need, and who have access to extra good markets, may generally grow the dwarfs with profit.* The parentage of the cion may affect //x value. — "It is probable that many trees fail to bear because propagated from unproductive trees. We know that no two trees in any orchard are alike, either in the amount of fruit which they bear or in their vigor and habit of growth. Some are uniformly productive, and some are uniformly unproductive. We know, too, that cions or buds tend to reproduce the char- acters of the tree from which they are taken. A gardener would never think of taking cuttings from a rose bush, or chrysanthemum, or a carnation, which does not bear flowers. Why should a fruit- grower take cions from a tree which he knows to be unprofitable ? "The indiscriminate cutting of cious is too clumsy and inexact a practice for these days, when we are trying to introduce scientific methods into our farming. I am convinced that some trees can- not be made to bear by any amount of treatment. They are not the bearing kind. It is not every mare which will breed or every hen which will lay a hatfull of eggs. In my own practice, I am buy- ing the best nursery -grown stock of apples (mostly 'Further remarks apon dwarf trees may be fouiid in Nursery- Book, 3d ed., and in Loderoan's "Dwarf Apples," Bull. 116, Cornell Exp. Sta. Raising Trees from Seeds. 235 Spy), and am top -grafting them with cions from trees which please me and which I know to have been productive during many years. Time will dis- cover if the effort is worth the while, but unless all analogies fail, the outcome must be to my profit."* If one is to plant hardy stocks and then work them over, he should usually plan to graft or bud them after they have stood in the orchard one year. Good results sometimes follow grafting in the very year in which the stock is set, but this is the exception. Some persons have proposed to sow seeds in the very spot where the trees are to stand, and thereby to raise stocks for top -working without transplanting them, but the labor and un- certainty of the method make it impracticable. It is cheaper to grow trees in the nursery row— the same as it is cheaper to buy trees of a nursery- man than to attempt to grow them — and the trees also receive better care. Again, seedlings vary, and the poor and weak ones should be discarded the same as they are by the budder in the nursery row who finds them to be too small or too scrawnjr to bud. Well -grown stock of a strong- growing variety usually gives more uniform results than a lot of home-grown seedlings can. Buying the trees. — It is best, when it can be done, to order trees late in summer or early in the fall, if *L. H. Bailey, Bull. 102, Cornell Exp. Sta. See, also, "Survival of the nHkf." pp. 249, 250. 236 The Principles of Fruit-growing. one expects to plant an orchard. Buy where the best trees can be obtained, and where there is good reason to expect reliable stock and honest dealing. It is generally advisable to buy at the nearest nursery at which the desired stock can be secured, for the buyer has more personal knowledge of the nurseryman, he can visit the nursery, he saves freight, and he may be able to secure his stock in fresher condition ; but trees of equal excellence will generally thrive equally well when transported from long distances, if they arrive at their destination in good condition. While one should endeavor to secure low prices, it should be remembered that nursery stock should never be pur- chased simply because it is cheap. Poor stock is dear as a gift. Yet farmers who annually plant a few trees, and who buy of agents, often pay exorbi- tant prices. In a certain town, when farmers were paying 28 cents apiece for peach trees in lots of a dozen, any reliable nursery would have been glad to have supplied the same varieties at $8 per hundred, at the nursery. Plums which should have sold for 15 cents to 20 cents apiece were selling to farmers for 50 and 60 cents apiece. The man who seriously ex- pects to plant an orchard for profit will not be led into any wild scheme or new varieties by agents. He will generally buy directly of the nearest nurseryman who can supply the desired stock and varieties at the prices which suit him. Some nurserymen employ reg- ular and reliable agents, and such agents carry a cer- tificate from the firm they represent. But while these salesmen may be perfectly straightforward, and may Substitution of Varieties. 237 be the best channels through whom small orders can be secured by those who are uninformed in porno- logical matters, all persons who expect to go into fruit-growing seriously should buy directly of the nurseries. But it must always be remembered that the tree agent has been the means of clothing the country with fruit trees, and of thereby adding much to the contentment of farm life. The buyer should make up his mind just what varieties he wants, and then find the nursery which has them, and order early enough to get them. There is then no occasion to consider the vexed ques- tion of substitution of varieties. If the varieties are not in market, buy stocks of some strong -growing, staple variety, and after these are established— usually the spring or summer of the next year — bud or graft over the tops to the desired varieties. THE SETTING OF THE PLANTS. When to plant. — There is much difference of opinion as to the relative merits of fall and spring planting. The writer's opinion is that fall planting is generally preferable to spring planting upon thor- oughly drained soils, particularly for the hardy tree fruits, like apples, pears and plums ; and if the ground is in good condition and the stock well ma- tured, peaches can sometimes be set in October, even in the northern states, with success. The advantages of fall planting are several. The trees become estab- lished during the open weather of fall, and they usu- 238 The Principles of Fruit-growing. ally make a start in spring before the ground is hard enough to allow of spring planting. This early start not only means a better growth the first season, but, what is more important, trees which get a very early hold upon the soil endure the droughts of midsummer much better than trees planted in spring. Planting is nearly always better done in the settled weather and workable soil of fall than in the capricious days and in the hurry of springtime ; and the orehardist is free to begin cultivation at a time when lie would otherwise be planting his trees. Again, it is generally better to buy trees in the fall, when the stock of varieties is full and when the best trees are yet unsold : these trees must be kept until planting time, and it is about as cheap and fully as safe to plant them directly in the field as to heel them in until spring. In fall planting, however, it is important to insist that the trees shall be thoroughly well matured. In order to move stock quickly, it is the practice of some nurserymen to "strip" the trees before the growth is completed; that is, the leaves are stripped off, the growth stopped, and the trees are put upon the market for September deliveries. This process weakens the trees, and many failures in young plan- tations are probably attributable to this cause. Such trees may die outright, especially if set in the fall and a hard winter follows ; or they may live to make a dwindling growth for the first few years. Like early -weaned calves, they lack vitality and push. If one were setting an orchard in the fall, he should Buy in the Fall. 239 place his order for trees in August or September, if possible, with the express stipulation that thf trees should stand in the nursery rows until the leaves begin to die and fall. In the meantime, the land should be fitted and the holes dug, so that when the trees arrive they can go directly into their places without delay or without the expense of heel- ing them in. Trees are mature enough to dig late in September or early in October in the northern states, depending upon the season, soil and variety. When the tree is fully mature, some of the leaves will still hold upon the vigorous shoots, and these are stripped off; but this stripping does no harm, for the young growth is then mature and it has a thick, strong, brown appearance which is very dif- ferent from the slender, soft and green branches of early -stripped trees. It should be said that there seems to be a ten- dency amongst nurserymen to urge fall planting in order to push sales ; and there are man y good planters who consider fall planting hazardous, espe- cially in the north. It is true that unless the con- ditions are right, spring planting is the safer course; and farmers who have many fall crops to harvest will also probably find more time for tree setting in the spring. Distance apart. — Fruit plants are oftener set too close together than too far apart ; in fact, the latter error scarcely exists. Trees, especially, are wide feeders ; and the best results are obtained when each tree stands far enough from its neighbors to 240 The Principles of Fruit-growing. allow it to possess an individuality all its own. An additional reason for sparse planting has lately become important, — the necessity of spraying for in- sect and fungous pests; and for this reason, as well as to allow of better cultivation, the outside rows should not be set close to fences. The distance at which trees may be set depends much upon the system of pruning. If heading-in is followed vigor- ously and systematically, trees may be set a third nearer than if allowed to take their natural form. Heading- in should always be practiced with dwarf pears, and many of our best growers pursue it with peaches, plums and quinces. Thin planting is the safer rule for the majority of cases. The following table may be supposed to represent the outside aver- age limit for the planting of fruits in New York, when the plants are allowed to take their natural form: Apples, 40 ft. each way. - dwarf, 10 to 15 ft. Pears, standard, 20 to 25 ft. — dwarf, 12 ft. to 1 rod. Quinces, 1 rod. Peaches and Nectarines, 20 ft. Plums, 20 ft. Apricots, 20 ft. Cherries, sour, 20 ft. — sweet, 30 ft. Figs, 20 to 25 ft. Kaki, 20 to 25 ft. Pecans, 40 ft. Distance of Planting. 241 Oranges and Lemons, 25 to 30 ft. Grapes, 6x8 to 8x10 ft. Currants, 4x6 to 6x8 ft. Blackberries, 4x7 to 6x9 ft. Raspberries, 3x6 to 5x8 ft. Strawberries, 1x3 or 4 ft. [way. Cranberries, 1 or 2 ft. apart each These are safe distances. In certain cases, how- ever, where the soil is strong and the grower makes thorough work of cultivating, pruning and fertilizing, these distances can be reduced somewhat with profit, except, perhaps, in the case of apples. (See, also, remarks by Van Deman, page 273.) The quincunx system plants in triangles rather than in squares. The triangles may be equilateral, in which case all distances are equal. Usually, however, s Hfth tree is set in the center of a square; this sjsiem therefore requires twice the number of trees needed i'or ordinary planting, not counting the uneven ends. The mixing of species, or .double planting. — These remarks upon the proper distances for trees call for some discussion of the common question as to whether it is good policy to plant shorter- lived trees, ns peaches, between apples and pears. It all depends upon the man. In general,- it should be discouraged; but if the orchardist gives the very best attention to fertilizing and cultivating, plantations can be mixed with good results. This mixing of species is a per- sonal question. Now and ther a man succeeds ad- mirably with it, but the greater number fail to 242 The Principles of Fruit-growing. secure very good results with more than one type of effort upon the same piece of land. Van Deman* writes the following upon this sub- ject: "For a number of years, the trees will neces- sarily have much more space than they really need, if planted the distance apart that they will require when grown to full bearing age. Not only will there be wide spaces between their tops, but much of the soil will be unoccupied by their roots. Therefore, some plan for using this space without in any way hindering the proper growth of the trees, is permis- sible, economical and desirable. Many plant peach trees among their apple trees to fill the spaces until the apple trees get old enough to need all the room. I have done so myself, but do not like it now. The peach trees are of quicker growth, and rob the apple trees to a damaging degree, in many cases. Dwarf pears are occasionally set in apple or standard pear orchards, but this is generally a mistake, because the trees often need very different culture, especially when the pear trees blight badly from too rapid growth. Moreover, if the dwarf pear trees are planted deep, they send out pear roots above the quince stocks, and become almost as long-lived as the other trees. The wiser plan is, usually, to plant apples, peaches, pears, cherries, plums, apricots, etc., by themselves, but to fill up the spaces until the permanent trees need the whole, plant varieties of *H. E. Van Deman, "Plans for Orchard Planting," Rural New-Yorker, March 6, 1897. Double Planting. 243 the same species that will come into bearing early. ''Not only do different kinds of orchards fruits re- quire different distances between their trees, but the same species or the same variety often needs more or less space in different climates and soils. Despite all the manuring or cultivation we may give them, those planted in some localities will not attain the same size as they would had they been planted in others. For instance: the peach trees of Connecticut and northern Michigan are much smaller than those of Delaware and Missouri. No manner of treat- ment will cause them to grow to the same size, unless those in the more southern locality were cut back in summer time or starved, and thereby stunted. It is climate that does it — more warmth, more sun- light, and, in short, more congeniality. The apple trees of Michigan and New England are far larger than those of Texas and the tide -water sections of Virginia, because the apple delights in a climate both moist and cool. The gigantic cherry trees of the Shenandoah Valley far exceed in size those which grow in the richer lands of Illinois. "Where land is dear, economy of space is an important point ; hence the plan that will put the most trees on a given area, provided they are not too thick, is the best. The more there are on an acre, the less it costs per tree to cultivate them." Some of the small -fruits may be planted in or- chards with the very best results. Strawberries are practically an annual plant, and are much better for orchards than any kind of a sowed crop is. 244 The Principles of Fruit-growing. How to plant the stock. — Plow the land and fit it well. As all fruit grounds should be put into culti- vated crops for the first two years, at least, it will generally be found advisable to plow the entire area before the place is set, rather than to plow strips where the trees or plants are to go, for the land can then be shaped better with reference to surface drainage and general convenience. Trees should be set neither in dead -furrows nor on back -furrows. Level culture should generally be adopted from the start, unless it is known to be necessary to displace surface water ; and in that case it may be questioned if the land is fit for fruit plants. In all ordinary soils, holes must be dug by hand for the tree fruits. Plowing out a deep furrow in the line of the rows may lessen the dig- ging and aid in getting the trees in line. The hole should be dug broad and ample ; and the harder the soil the larger ought the hole to be, for in that case the loose dirt which is filled in must give the tree its start. In loose and deep soils, the hole need be no larger than the spread of the roots. Chop up the soil in the bottom of the hole, or throw in a few shovelfuls of loose surface earth. Trees should be set an inch or two deeper than they stood in the nursery, for the loose earth will settle and wash away in the course of the season, even if it is well packed when the trees are set. Dwarf pears should be set from three to six inches below the bud. The roots are trimmed, as ex- plained further on. Every care must be exercised Setting the Plants. 245 to get the soil thoroughly firmed in about the roots — which are straightened out in approximately their natural position — and especially under the crown or fork of the roots, in order that no air-spaces may be left to dry out. This dirt can be best placed by fingering it in, moving the tree gently up and down at the same time. Once or twice in the pro- gress of filling the hole, the earth should be stamped down. Fill the hole to a little more than level full to carry off surface water, but be careful that no hollows are left too close about the tree into which water can settle, especially when planting in the fall. Stamp or pound the earth very firmly about the tree before leaving it, for the double pur- pose of retaining moisture and of holding the tree against winds. Small stuff, like nursery stock and small-fruit plants, may often be well planted by means of a dibber or spud. All this operation of planting can proceed to perfection only when the earth is dry enough to crumble. Stock cannot be well planted in wet and sticky soil. If trees are set according to these directions, and the tops are cut back as explained farther on, there will rarely be any necessity for staking and tying the trees to keep them plumb. Mulches of straw or manure are sometimes ad- vised for newly set trees. For trees planted late in spring and upon droughty soils, a light mulch about the tree may be advised ; but in other cases it is not. If mulches are applied to fall -planted trees, care must be taken to tramp them down well, or 246 The Principles of Fruit-growing. they may become a nesting -place for mice, which may girdle the trees when there are heavy snows. There are those who favor placing a forkful of ma- nure in the bottom of the hole, but this is a practice of doubtful value ; and, at all events, the manure should be well mixed with the soil to pre- vent drying out. There is often discussion as to whether it is desirable to place the mulch on the surface or to place it an inch or two below the surface and cover it with soil. No dogmatic as- sertion can be made for either method, although, of the two, the former is probably more generally advisable. But it should be remembered that a mulch of tilled earth (as explained in Chapter III.) is more desirable than one of straw or manure in general fruit -planting. Puddling the roots is a good practice when trees are to be shipped any distance or when they are likely to be unduly exposed, and it is a common practice amongst nurserymen. The operation con- sists in sousing the roots in a thin mud or paste of clay. Trimming the trees.* — There is much difference of opinion as to the best method of trimming trees when they are set. So far as the root is concerned, it is advisable, in the north, to cut away only those roots which are broken or badly torn. These should be cut off just back of the injury. It is the custom "Complete discussions of pruning and training, with a full analysis of th* Stringfellow or stub-root method, may be found in "The Pruning-Book." Trimming the Young Tree. 247 to cut off the ends of all roots of the size of a lead pencil or larger, for a clean, smooth wound is sup- posed to heal quicker than a ragged one. These cuts are made from within outwards, so that the wound is more or less slanting across the roots, and so that it rests firmly upon the ground when the tree is set. When the tree is planted, all the roots should be straightened out to nearly or quite their normal posi- tion. If it is found that one or two roots run off to an inordinate length, they may be cut back to corre- spond somewhat with the main root system. Perhaps half the entire root system of the young tree is left in the ground when it is dug. It is there- fore evident that the top should be cut back to a cor- responding amount. In fact, the top should be more severely shortened -in than the root, because the root, in addition to being reduced, is also dislodged from the soil, with which it must establish a new union before it can resume the normal activities. Trees which are allowed to carry too much top when planted may fail to grow outright ; or if they start, they are very likely to be overtaken by the droughts of summer. Even if they live, the growth is gen- erally small and uncertain, and the tree may fall a prey to borers or a victim to high winds. On the other hand, trees may be trimmed too severely when set. Except possibly in the case of peaches, it is probably unwise to trim the trees to a mere pole ; and with peaches, it may be better to leave spurs with at least one bud than to trim to a whip. There should be a number of strong, bright buds left upon 248 The Principles of Fruit-growing. the top, for these are the points where early and active growth begins. These buds are upon strong branches. If they are removed, the weaker or halt' Fig. 23. Yearling peach tree. Fig. 24. Peach tree, pruned. dormant buds upon the main trunk or low down in the crotches, must take up the work, and these start slowly and often feebly. Trimming the Young Plant. 249 There are two general methods of trimming the tops of young trees at planting time. One method cuts back all the branches to spurs of from one to three buds ; or sometimes, particularly with dwarf pears set when two years old, the side branches may be cut entirely away, leaving only the buds on the main stem or trunk. The tree, therefore, " feathers out" the first season; that is, it makes many small shoots along the main trunk. The following fall or spring, the top is started at the desired height. Fig. 23 shows a peach tree as received from the nursery, and Fig. 24 the same tree, trimmed in this manner, ready for planting. This method is the one generally best adapted to the peach, which is always set when a year old ; but for other fruits, unless the trees are slender and without good, branchy tops, it is doubtful if it is the best practice. If the bodies are thought not to be stiff enough, this man- ner of trimming may be used to good advantage. The main shoot should usually be headed back in this as in all styles of trimming, in order to make the trunk stocky. The second method aims to start the top at the required height when the tree is planted. It is adapted only to strong and well grown stocks which have a more or less branching and forking top. From three to five of the best branches are left, and these are headed back to a few buds each. Fig. 25 shows a pear tree, trimmed in Fig. 26, and the illustration may be considered to represent a good example of its class. Many of our best plant- 250 The Principles of Fruit-growing. ers prefer the spur system for all trees, and there are some who would trim all newly set trees to a Pig. 25. Three year old pear tree.

It is, of course, evident that there is no one method of pruning young trees which is all wrong, nor any other which is all right. The method must always be modified by the age and shape of the trees, by the climate (or part of the country) in which the plan- tation is set, by the species of plants, and especially by the ideal which the grower has set for himself. In general, it may be said that the younger the stock the more nearly to a whip it may be pruned. Fig. 30. Grape plant, showing where it should be pruned. Trimming the Young Stock. 253 It may be said in general, then, that peach trees and small or slender trees should be well headed back and spurred (Figs. 23, 24); but that strong, well branched trees may have the Lend started at the desired height at the time of setting, all the branches being well headed back (Figs. 25 and 26). Fig. 27 shows a small plum tree cut to spurs, and the roots have also been properly dressed. Figs. 28 and 29 show second- class apple trees. In these the tops are not well formed, and it might be best to trim to a whip, allowing the branches A to be- come the leaders. Such whips may look very crooked and scu'awnjr, but they will straighten as they grow.

Pruning a newly-sei tree. 254 The Principles of Fruit -growing. The trees may be trimmed before they are planted, although it is generally better to do it just after they are set, especially if the tree is trimmed after the method of Fig. 26, for one can then better esti- mate the proper height, the operation is easier done, and there is no further danger of breaking off the limbs by the handling of the tree. One foot is planted firmly at the base of the tree, and then with one hand the branch to be removed is bent upwards and with the other the knife is applied to the under side and the cut is made neatly and easily (Fig. 31, page 253). Never cut downwards on a limb, for a ragged wound nearly always follows. In fall -set trees it is generally inadvisable to prune them before spring (unless the tops are so heavy and the bodies so weak that they are likely to be injured by wind), because the cut surfaces are likely to dry out. The roots of the tree are not yet sufficiently established in the soil to supply the added evaporation which takes place from the wounds. If it seems to be desirable to trim the trees when they are set, they should be cut back only part way. They may be cut again, to fresh wood, in the spring. THE LAYING -OUT OP THE FRUIT PLANTATION. It is difficult to make the rows straight in large areas, especially on rolling ground. Persons who have had areas regularly surveyed with chain and compass, and a stake set for every tree, may have Making the Rows Straight. 255 found the orchards to be as crooked as others set with much less care. The surveyor sets his stakes by sighting across the field from certain fixed points ; but it is difficult for the planter, when the stake is removed and the hole dug, to stand the tree in the exact place of the stake. It is better to regard the trees as stakes and to set them by sighting. The area can be "run out" on two or three of the sides, a conspicuous stake being set at the location of each tree on these outside rows. If the field is large or rolling, it may be necessary to set one or two lines of stakes across the center of the field also. For areas of a few acres, a garden- line stretched across the field will be found to be a great help and to save much time. This line is moved at either end to the adjoining row, as soon as one row is set alongside it. Persons sometimes tie conspicuous strings on the line at the given intervals between the trees, expecting to set a tree at every knot, but with the stretching of the line, and other sources of error, it is nearly impossible to get the cross rows straight in this manner, and the trees must be kept in line by sighting. Upon comparatively level fields, especially if the land is in good tilth, the plantation may be laid out with a corn -marker. If the planter keeps his back to the row of trees and sights ahead to the marked line or furrow, he will get his rows straighter than he will if he sights by the trees. Two men are better than one when setting plants, for one usually attends to the sighting whilst the other 256 The Principles of Fruit-growing. puts in the plants. There are various devices for locating the position of the original stake, after the hole has been dug. One of the best consists sim- ply of a thin board three or four inches wide and six or seven feet long, with a notch at its center, and a stationary leg or pin at one end (a). The other end (b) is provided with a hole to receive the top of another stake or pin. The notch is set against the stake, the legs at each end of the board being thrust into the ground at the same time. The end (b) is now raised off the pin or leg, and the board is swung around out of the range of the hole. When the hole is dug, the end (b) is swung back and dropped upon the pin, and the tree is set in the notch.* The methods of laying out orchards have been discussed in detail recently by H. E. Van Deman, formerly pomologist of the United States Depart- ment of Agriculture, and copious quotations are made from these writings. t "To lay out with the plow. — Before doing any- thing, one must decide which style or arrangement of the trees is to be followed and the distance apart to plant them. This having been decided, the first thing to be done is to establish a base line, which should be along a fence, road or some other perma- nent border of the tract to be planted. Prepare The reader will find this implement and another one illustrated on page 56 of " Garden-Making." tH. E. Van Deman, "Laying Out Orchards," Green's Fruit Grower, April. 1897. Making the Rows Straight. 257 enough small split stakes, that may be easily seen, to put at each end of every tree row; that is, enough to go entirely around the tract. Then, set a stake firmly at a spot which shall be the first established corner of the outside limits of the orchard. It must, however, be set at a spot which shall also be the end of another line running exactly at right angles to the base line. In the west, where the farms are nearly all laid out in perfect squares or rectangles, the field.-* are apt to be rec- tangular. In the absence of a surveyor's transit, a carpenter's square may be used to establish the lines, by sighting along its edges when laid on the tops of three stakes at the corner. Set a stake at the farther end of each of these lines. From this first corner stake measure along the base line fifteen feet, or as far as it is thought best to have the width of the margin between the trees and the fence, and there set a stake. Next, measure along the base line from this second stake the distance that the trees will be apart, and set a stake. Measure along the entire length of the base line, setting a stake at every 16%, 20, 25, 33 feet, or whatever distance may have been decided upon. This line of stakes being only the ends of the transverse rows and not the places for trees, they need not be set absolutely in a straight line, but should be nearly so. Then, go back to the original corner stake and measure fifteen feet at right angles to the base line and set a stake, which determines the width of the border next the base line. Now, 258 The Principles of Fruit-growing. measure and set stakes along this other side of the orchard site, up to the stake at the farther end. The two remaining sides should be measured and staked in the same way. "Provide several tall stakes with a white rag tied at the top of each, to use as sight poles at each end. If one can run a straight line with a plow without intermediate sight poles, that is, with only one at each end, these will be enough ; but I have found that it pays ro have an extra line of stakes set a few rods from each end, and a guide pole to be set at each in turn, as the laying -out pro- "We are now ready for the plow. Some like one horse, but two make the plow run steadier, and it is easier for the plowman to sight between two horses than over the head of one. My plan is, to first mark out crosswise to the way I intend to plant, and to make but a single shallow furrow. This being done, we are ready to make the fur- rows in which to plant. If these run up and down the slope they will act as a drain to the trees, in some measure. By plowing two rounds and finishing with a dead -furrow or trench on the line, and then subsoiling in the bottom of it, there will be very little work for the spade in preparing to set the trees. It is by no means difficult to set them in the checks, with a little sighting, so straight that no one would know but that they were set by a line. After setting the trees, hitch one horse to a plow with a very short singletree covered Making the Rows Straight. 259 with rags at the ends to prevent injuring the trees, and fill up the trench at two rounds. Then plow the space between the rows. One thing must be very carefully figured out the very first thing, if the hex- agonal style is used (which I prefer and use), and that is, the distances between the rows at right angles, and not diagonally from tree to tree, and then accurately measured and staked on the outer lines. The great Wellhouse orchards, in Kansas, were laid out with the plow. J. H. Hale substituted a 60 -cent per day darkey and a mule for a six -dollar surveyor and transit, in laying out his rows for planting his 600 -acre peach orchard in Georgia. "Laying out with a line. — For small orchards of an acre or two, I have often practiced a method of laying out in the hexagonal style, which is very quickly and easily done. As many stakes are pro- vided as there are trees to be set. A wire is pre- pared of the exact length that the trees are to be apart, and a ring or loop twisted in at each end, by which to hold it. A base line is established by setting stakes just where each tree will be in the first row. One person (A) slips a finger through one ring, and another (B) takes the other end of the wire and runs a small stick through the ring. A holds his end exactly at stake 1, and B steps to where he supposes the first tree of the second row will come, and with the point of his stick marks a small segment of a circle on the ground. He remains there while A goes to stake 2 and holds his end exactly to it. B describes another arc on the 260 The Principles of Fruit-growing. ground, and where it crosses the first one he sets a stake, and moves to the place for the next stake. There he makes a mark, and A then goes to stake 3 of the base line and holds the wire as before, while B finds the crossing of the marks and sets another stake ; and so on to the end of the row. When the second row is complete it is used as a base line from which to make a third, etc., etc. If the work is done carefully the stakes will be found to be in very straight rows every way. I have tried it on some of the roughest hills in northern Michigan, where, in newly cleared places the stumps were very thick, and planted nice orchards that are now over twenty -five years old, that look to-day as if the trees might have been set by a compass and chain. On level ground, free from obstructions, it is fun to lay out an orchard so. "Another line method. — Another cheap and handy method is, to mark and set by a wire long enough to reach entirely across the field. It should be stretched tightly between two stout stakes that have been firmly driven into the ground, and exactly on the line of the first row to be planted. Directly over the place for the first tree or vine, wrap a small wire two or three times and twist the ends tightly, so it cannot slip. Measure along the wire to the next place and fasten another wire coil, and so on to the end. If these little coils were soldered fast they could not move. A little piece of bright cloth should be tied over them, that the places may be easily seen. Now, dig the holes and plant the Staking Out an Orchard. 261 first row while the wire is in place. Then move the wire and stakes to the second row and stretch as before, being very careful to have the first mark exactly where the first tree should be. Proceed to dig and plant as before. Move the wire to the third row, and so on throughout. This obviates all necessity for marking off upon the ground, except the distances between the rows and a starting point on each row. Some of the most accurately planted orchards and vineyards I have ever seen were planted by this method at the North Carolina Experiment Station at Southern Pines, and elsewhere in that region, and there I got the idea. It is entirely practical. The wire can be wound on a reel, and thus be easily moved about the farm or stored for further use." Staking methods.— There are so many methods of staking out an orchard, that it will interest the reader if one of the best of them is described. The Yeomans plan is as follows : * "In connection with the accompanying diagram, is explained an easy, simple and accurate way of marking out the ground and planting the trees without putting any stakes where trees are to be planted or removing any while planting. The stakes not only show where to dig the holes, but when the planting is to be done the same stakes indicate the precise place where the trees are to be placed, always sight ing only by the stakes in setting, without any regard *T. O. Yeomans, Walworth, N. Y., Country (ientlemau, Ixi. 288 (Apr. », 1896). 262 The Principles of Fruit-growing. to the trees planted. Thus all the stakes will be standing when the last tree is planted, showing the accuracy of the work done. "The outside line of the diagram represents the A ID NORTH F G SOUTH Fig. 32.

The ground being properly prepared for one hundred trees, pro- Staking Out the Ground. 263 vide sixty lath as very suitable stakes— light, straight and of proper length — lay them on the ground or a board and whitewash on each side about a foot or more at one end, by which they can readily be seen at a distance and distinguished from any other stake or object. Let two men with a tape line start at the corner of the ground at D, and measure 25 feet along the east side to 1 and then set a stake ; thence measure 40 feet to 2, setting a stake, and continue to 10, putting a stake every 40 feet to C, setting all stakes as perpendicular as possible. "Then with ten stakes start at B and measure the same distance toward A, sticking a stake first at 25 feet, and after that 40 feet, to correspond with those on the east side. And on the same plan and in the same manner, stick ten stakes 40 feet apart along the north and south bounds of the orchard, and entirely outside of where any trees are to be planted, being particular that no trees shall be planted nearer than 25 feet to the fences surround- ing the orchard, for the reason that when the trees become large, as much as 25 feet of space will be necessary to allow a spraying wagon and fixtures to pass in spraying the trees properly, and to place ladders about the trees for gathering the fruit. "The stakes being set around the orchard ground at proper distances, the tape line is no longer needed, as the cross intermediate rows of stakes are to be set by sight. Now let one man take ten of the white -top stakes and go about to E (at bottom 264 The Principles of Fruit-growing. of diagram, and another man go to the first stake north of D, and sight the man at E precisely where to stick a stake in line with the two stakes on opposite sides of the ground ; then move north- ward to 2, and stick a stake between 2 and 2; and thus continue from south to north and from east to west, through and not far from the middle of the field, being careful not to place either of these intermediate rows where a row of trees is to be planted. These rows need not be straight, but each stake must be in line with the corresponding stakes at the right and left. "With the stakes thus placed, a person moving anywhere about the ground to be planted can readily find, by looking in the direction of two stakes in two directions at right angles, precisely where a tree is to be planted. Thus, a person standing at either + is at a point where a tree must stand, and at either of those points will see two stakes in a line with him in two directions at right angles ; and so of every point where a tree is to be planted. If men are to be employed to dig the holes who are not capable of setting a stake in line with two other stakes already standing (there are such men), let some one who can do so go through the field, and with point of stake or other thing, mark where the holes are to be dug. "With this arrangement no stakes are placed where the trees are to be planted. Any number of men can go on with the work of digging the holes and planting in any part of the orchard without Hexagonal or Quincunx Planting. 265 reference to any other trees in any other part. The writer has planted about 150 acres of apple and 100 acres of peach orchard on this plan, and has furnished many parties brief descriptions of same for planting ; has planted rows 30 to 40 rods long of nice trees, so straight in line that a stake two inches in diameter set up in the row would hide every tree from view, looking from the end thereof." Orchard plans. — Van Deman* writes fully upon the methods of constructing a plan of an orchard, as follows : " The hexagonal, Van Deman plan. — The plan that will best (•cononiize space is what is known as the ' hexagonal ' plan. It is a system of equilateral triangles, and is sometimes called the ' triangular ' system. It puts all adjacent trees equally distant from each other. This is the plan I have followed in all my own plantings, and now think it the best I have ever seen. I have practiced upon the additional idea of planting temporary trees alternately with permanent ones, and leaving 'alleys be- tween every fifth and sixth row, which I have never seen in any other orchards of the hexagonal style ; therefore, I have called this part of it the ' Van Deman ' plan. In the lower part of Fig. 33 it may be seen. By this plan there may be planted 156 trees per acre one rod apart, with every sixth row left out for an alley, which gives easy access to wagons for gathering fruit, and for any other necessity. The permanent trees are marked by the letter P throughout this and all the other plans. These trees are two rods, or 33 feet, apart, which, for apple trees in most climates and soils, is sufficient. In Michigan, Pennsyl- vania, New York and some other localities where apple trees *H. E. Van Deman, "Plans for Orchard Planting," Rural New-Yorker. March 0 and 13, 1897.

The places for the temporary trees or, 'fillers,' are designated by the letter F.

But, aside from his published statements of the results of his enterprise, I know, from a long 270 The Principles of Fruit-growing. and intimate acquaintance with Judge Wellhouse and his or- chards, that they have done remarkably well. "The Parker Earle plan. — The plan originated by Parker Earle, who is one of the leading western horticulturists, is shown at Fig. 36. He has planted several hundred acres of apples after this plan in the famous Pecos Valley of New Mexico, where the trees come into bearing very early. They are 16 feet apart east and west by 20 feet north and south, except that every sixth row is left out for an alley, as in the lower section of the diagram. There are 108 trees per acre. The intention is to cut out every other north and south row, thus leaving them as shown in the middle sec- tion, 32x20 feet. There will then be 63 trees per acre. One -half of these may be taken out later, if more space be needed, leaving at the rate of 32 trees per acre, 42 feet apart. This will give ample space when the trees get to be very large; but in that climate, and northward to Colorado, Utah and Idaho, the trees are so precocious, and bear so abundantly, that it is doubtful whether they will ever attain size to need so much space. "The Olden plan. — Who has not heard of the famous Olden Fruit Farm, in southern Missouri ? I made three prolonged visits there to see it at different times of the year, and it is well worth seeing. The oldest parts of the apple orchards are just at good bearing age. It is planted mostly to apples and peaches, but there are a few pears, plums and small fruits. Each year more are added; last year 960 acres were planted. J. C. Evans and L. A. Goodman are the leading spirits of the company that owns and runs it. Their plan for apples is 25x25 feet, in plain squares, and all of one variety in a block, making 64 trees per acre, as in the lower section of Fig. 37. The trees have not come to the age that requires thinning by the ax, but they will do so in time, for apple trees grow to a very large size in that rich soil and agreeable climate. When it does come, they will take out every other diagonal row, leaving 32 trees per acre, 37% feet apart the nearest way (diagonally), and 50 feet east Plans of Orchards. 271 and west, as in the upper section. While it may seem pre- sumptuous for me to suggest an improvement on a plan so well matured, and by such eminently practical orchardists, and, when it is true that the apple bears quite young and pro- fusely in all that Ozark Mountain region, yet it does seem (NOETH.)

This modified plan I have depicted in the central section of Pig. 37. 272 The Principles of Fruit-growing.

The contour of the ground and intervening rocky hillsides or oak forests left standing, do not always permit these blocks to be of regular size or shape. "Then, we have the great Hale peach orchards in Georgia and Connecticut, and who has not heard of them and of Plans for Peach Orchards. 278 their stirring Yankee proprietor, J. H. Hale, of Connecticut f He plants 13 x 13 feet, which seems extremely close, even for peach trees in Connecticut. As I walked through them with Mr. Hale, I repeatedly expressed such an idea, but he refuted it as often, gave favorable statements from experience, »nd then he would say, 'There are the trees; do they not look thrifty enough ? ' And I could not say but that they did. But he feeds them like a lot of pigs in a pen. He prunes them back to bearing, paying and convenient size. He is not growing peach trees for fuel simply; although they will go into the wood and brush piles whenever their day of usefulness is over, and others be planted in their stead. Streets are laid out both ways through his Georgia orchard of 600 acres, cutting it into regular blocks 1,000x500 feet in size. There are 289 trees per acre, as may be seen in the upper part of Fig. 38. "The Delaware and Maryland peach orchards are set wider than those already mentioned. The trees grow to large size, and utilize the 16 to 20 feet space given them. The Michi- gan peach orchards are set somewhat closer, and those of the northern part of the peach belt along the lake are de- cidedly so. I have visited all of these sections and exam- ined the orchards, finding the square or hexagonal styles the most popular. In Texas and California I saw large, thrifty peach trees that needed as much space as any, and planted in the most exact manner, usually in squares or hexagons, at from 18 to 24 feet apart. "The pear, cherry, plum and prune (some plums are called prunes, especially in the Pacific states), taking the country over, are all subject to the same conditions and variations of climates and soil as the apple and peach, and, like them, they can properly be planted in any of these styles men- tioned, the distances being changed to suit each. The pear, being an upright grower, as a rule, does not need so mucn room as the apple; 20 feet apart is a common distance to plant standards, and 10 to 12 feet for dwarfs. The Kieffer, Le Conte and Garber bear very early as standards, and may 274 The Principles of Fruit-growing. be planted about 16 feet apart, and thinned out as they crowd each other. " The sour cherries need about 18 to 20 feet, while the larger -grow ing sweet varieties require fully 20 feet, and in time, if they are not pruned back severely, 40 or more- feet when they attain their full size. Plum orchards should vary APPLE TREE Fig. 9 Ft. 6 Ft. 6 Ft. 9 Ft. 19. Setting small-fruits in an orchard. somewhat in closeness with the varieties planted. The great prune orchards of the Pacific slope are set with about 20 feet between the trees. The orchards of our native species require about the same room; but the Japanese class is usually more upright in growth, and may be planted a little closer."

The trees are planted on the hexagonal plan, the rows being 30 feet apart and the trees 35 feet apart in the rows, the trees in one row alternating with those in the next. By this method of arrangement, 15 per cent more trees can be planted to the acre than by the ordinary method, and yet not be any more crowded. The bushes are 6 feet apart one way by 5 feet 10 inches the other. At present no trees are nearer than 9 feet to the apple trees. As the trees increase in size, those bushes within the circles, as shown on the plan, will be the first to be removed." The family fruit plantation. — It is impossible to give any specific advice for the plan of a family fruit garden, because tastes are so personal, and the amount and character of land at the disposal of the party are so various. One can only say that the varieties should be chosen for best dessert and culi- nary qualities, for succession through the season, and that the area should be so planted that the rows run the long way of the land and to allow of easy cul- tivation with a horse. In general, it will not be necessary to provide for cultivation both ways. The accompanying diagram (Fig. 40) suggests how an area of one acre may be laid out in a fruit garden for the home supply. For a number of years, other plants — as vegetables, small-fruits, or dwarf apples or dwarf pears — may be grown, not only between the rows, but between the trees in the row. CHAPTER VI. THE SECONDARY AND INCIDENTAL CARE OF THE FRUIT PLANTATION. THE methods of tilling the fruit plantation have been fully considered in Chapter III., but since the subject is so important and so commonly misunder- stood, it may be well to repeat two or three of the advisory suggestions at this place. There are many persons who fully believe that clean tillage is the proper treatment for an orchard, but who are de- barred from putting the matter into practice because of the great amount of labor which they conceive to attach to it. As commonly practiced, it is certainly true that the tilling of orchards is one of the most laborious duties of the farm, but this is because the accustomed methods are wrong or bungling. The orchardist rarely has the land fully under his control. The essence of the whole matter is to get the land in ideal condition whilst the orchard is young, and then to practice surface tillage (with only occasional plowings) after the trees begin to bear. The use of modern implements makes it easy to keep the land clean without resorting to the high trunks of the old-time orchards. If the roots are made to strike deep into the land by deep plowing for the first (277) 2?8 The Principles of Fruit-growing. few years, it may not be necessary to turn any furrows in the plantation in later years, except to turn under cover crops. • All this can be done even with hard clay land. The writer has the management of two orchards upon very hard clay of uneven surface, which, in six years from the setting of the trees, is in such con- dition that deep plowing is no longer necessary, and the spring fitting of the land is done with spading harrows and spring -tooth harrows, and the subse- quent tilling is partly done with a spike -tooth har- row. Weeds are not allowed to appear ; but if a patch should get a start now and then, it can gen- erally be destroyed with the cultivator. Perhaps once or twice during the season it will be necessary to send a man through the orchard with a hoe to take the weeds away from the trees, but the space which needs such hand labor will not exceed two feet in diameter, and it is usually very much less. This has been accomplished by exercising great care to plow the clay when it is in such condition that it pulverizes when it is worked, and by the incor- poration of one or two cover crops. It will be necessary now and then to put cover crops on the land for the purpose of adding humus, and the land will then be regularly plowed in spring to turn the crop under ; but even then it may not be the de- sire to secure a heavy growth of cover crop, and the spring plowing need not necessarily be deep and laborious. If, however, it seems to be necessary to plow six or eight inches deep, there will be no Roof -pruning. 279 hesitation in doing so, for the roots are deep enough to escape the plow if the plowman is ordinarily careful about the trees. It is not necessarily a misfortune to cut the smaller roots of plants with the plow, providing only a few are cut in any year. In other words, it is no doubt safer to sever a good many roots a Fig. 41. A broken grape root sending out branches. half inch, or sometimes even an inch, in diameter, than not to plow the orchard at all. The severed roots generally send out numerous branches near their ends, and these branches increase the forag- ing power of the root in soil which is normally laid under small tribute. Figs. 41 and 42 are drawn from actual specimens of roots which were broken by the plow. It would seem as if the absorbing 280 The Principles of Fruit-growing. area of the root had been actually increased, for the many small roots certainly present more surface than the main shaft of the root did. It must be remem- bered, however, that the real surface of the original root extended far beyond the present point, and there is no way of telling if the adventitious roots actually present more surface than the whole of the original root did. But it is probable that an occa- Fig. 42. Showing the numerous adventitious branches of a broken npple root. sional light root -pruning may do more good than harm in some cases. The particular methods of caring for plantations of small -fruits can scarcely be discussed in a gen- eral work on fruit-growing, but in general it may be said that a deep cultivation with a spring -tooth cultivator (No. 9, Fig. 13, page 147) is usually suffi- cient for breaking up the ground in spring amongst bush -fruits, if the land is clean and in good con- Study of Soil and Climate. 281 dition. If the land is soddy or infested with bad weeds, however, a regular plowing may be necessary. A handy plow for such plantations is one of the type shown in Fig. 16, page 158, managed by a single horse. The management of the land in small -fruit plantations does not differ in principle from the management of orchard lands, and the tools are of the same general kind, except smaller and generally adapted to a single horse. If the rows are far enough apart, however — as they usually are in blackberries and black raspberries — it may be necessary in hard lands to hitch two horses to such a tool as the spring -tooth cultivator. It is scarcely necessary to repeat that it is essen- tial to give the fruit plantation just as good tillage as the corn receives, if equally good results are desired. Wholly aside from the direct benefits of tillage (which have already been explained), the operation is necessary in order to supply the enor- mous quantities of moisture which are exhaled from the leaves of the plants. Professor Burrill, of the University of Illinois, estimates* that a good -sized apple tree, having 25,000 square feet of evaporating surface, which is not a large estimate, will give off 31,200 ounces of water per day in the hot season, or say 250 gallons. It is generally a matter of a few years to thor- oughly learn one's soil and climate, after moving onto a new farm. The farmer has a local and per- * Trans. 111. Hort. So.'. 282 The Principles of Fruit-growing. sonal problem to apprehend and to solve. He should not be discouraged, therefore, if he does not secure the desired results from the treatment of his land within the first two or three years. THE GENERAL CARE OF THE PLANTS. Staking young trees. — If fruit trees are stocky and well planted, and if the land is deep and in good condition, it will rarely be necessary to stake them. The staking of an orchard is generally an indication of poor trees or poor management at some point. It occasionally happens, however, that trees must be staked to enable them to overcome some accident or injury, as breaking by heavy winds, or ice, or other means. When it is neces- sary to stake trees, it is ordinarily preferable to drive a stout stake upon two sides and then to bind the tree firmly to each of these stakes, in order to keep it from whipping. The best bandage is one of burlaps or other strong, soft cloth, cut in strips two or three inches wide and firmly tied about the tree. Just as soon as the tree has recovered from its injury or weakness, the support should be removed. Trees which have blown over, but which have not been broken completely off, may be severely headed- in and tied up in this manner, often with the very best results. The wounded and broken surfaces should be thoroughly covered with some antiseptic wash or paint. Sun -scald.— It is often necessary, especially in Shading the Trunk. 283 the hot plains regions, to shade the trunks of young trees in order to prevent sun -scald. In the nursery rows, the bodies of the trees are ordinarily well shaded. There are various means of provid- ing this shade, but the best results may be ex- pected to follow from some protection which simply breaks the force of the sun and does not entirely obstruct it ; for in the latter case, the bark does not so read- ily become inured to exposure to sunshine. Finely woven wire net- ting rolled around the tree (in more than one thickness, if necessary), is said to afford very good protection for this pur- pose, as shown in Fig. 43 (but preferably ex- tending higher up the trunk). The upper part of the trunk is likely to be shaded sufficiently by the branches of the tree, although this is not always the case. These rolls of wire netting also serve a purpose in keeping away mice and other vermin. Fig. 43. Tree protected by a roll of netting. 284 The Principles of Fruit -growing. Hansen* writes as follows upon this subject for Dakota conditions: "Sun -scald causes great loss in northwest prairie orchards. By sun -scald is meant the alternate thawing and freezing of the stem on the southwest side in late winter, causing the bark to die and decay. Oftentimes the dead, blackened bark separates entirely from the stem. Orchardists now generally recognize the cause of the trouble, and prevent it by shading the stem in some way. Trees planted and kept with stem leaning toward the southwest until the branches shade the trunk, are free from it. Some fruit-growers set a board, or two boards nailed together trough -fashion, on the southwest side ; others use corn stalks, wire netting, or lath. Low -headed trees are best for severe lo- cations ; in more favorable sections trees may be headed two -and- a- half to three feet high. Tall trunks suffer more from sun -scald and severe winds." Trees are apt to suffer with sun -scald after a heavy pruning, especially if they have been allowed to grow too thick in the first place. Cutting out heavily from the center of the tree exposes the oblique and horizontal limbs to the intense heat of the sun, and the bark is likely to blister and be killed, after which borers are very apt to finish the work of destruction. In all interior hot regions, there- fore, it is well to exercise caution in the pruning of the tops of trees. It is better to keep the top *N. E. Hansen, "Fruit Culture," Bull. 50, S. Dak. Exp. Sta., 1897. Washing tht Trees. 285 somewhat thin and open from the start, rather than to allow it to become overgrown and then to make a sudden and radical correction of the difficulty. Bark-bound trees.— When a tree has been allowed to become stunted for two or three or more years, it is likely to become hide -bound, so that growth is impeded, even though the care of the plantation be corrected. The bark becomes very thick and dense and tight, and is likely to be dull and lifeless in color and sometimes moss -covered. The newer and fresher parts of the tree are likely to show a tendency to overgrow the lower parts which are hide -bound. In all such cases, the bark should be softened so as to allow the trunk to expand. In general, the best means of loosening up the bark is to scrape off the outer hard layer, if it should become mossy or en- tirely dead, and then to wash the tree thoroughly with some soapy compound. This washing should be done with a broom, or preferably with a strong scrub- bing brush, so that the body may be vigorously scrubbed. A wash of strong soapsuds is very good. Tar soap, whale-oil soap or carbolic soap are also very useful for the purpose.* These washes have the effect of softening the bark and allowing the tree to grow more readily. The effect of a good wash upon orchard trees is often exceedingly marked. It is sometimes thought by orchardists that the potash in rlit'st- washes is absorbed through the bark, and thereby stimulates the tree. It is probable that it * The reader uiay tiud various recipes for washes in "The Horticulturist'* kuleBook." 286 The Principles of Fruit-growing. eventually becomes plant -food by being washed off onto the soil, though the chief value of the wash is no doubt the softening and loosening effect which it has on the bark. Another means of releasing the pressure upon hide -bound trees is to slit the bark the entire length of the trunk or hide -bound portion. This is done by simply thrusting the point of a knife through the bark until it strikes the wood, and then drawing the blade down the entire length of the portion to be treated. When the knife is withdrawn, the slit is scarcely visible ; but after a time the slit widens, as the tree begins to expand. This method is to be advised only as an extreme resort, for it is better to keep the bark fresh and elastic by good tillage and by the use of washes ; but the slitting is of no damage to the tree, as a rule. The washing also has the additional advantage of killing Carious insects and their eggs which may be in or about the bark. Spraying with Bordeaux mixture will kill the lichen or "moss" on the trunks. Scraping trees. — The outer layers of bark of any tree gradually die and peel off, as the tissue grows upon the inside. This old, rough bark is of no direct use to the plant, but it probably affords some protection to the tender tissues within. It also af- fords a lodgment for insects and fungi. Trees which are kept in a good condition of growth and which are watched carefully, will need very little attention in the removing of the bark, but if the shaggy bark accumulates to any great extent, it is well to scrape Scraping Trees. 28? it off. The operation should be done when the warm weather approaches in spring, or, in fact, at almost any time in the growing season. A good tool for this purpose is an old and thin hoe, the handle of which is cut down to about two feet in length. This tool is grasped lightly in the hand and is raked up and down the tree, and it removes the rough bark with ease. The very best tool for the purpose, however, is that shown in Fig. 44, which is a steel plate with sharp, ground edges, fas- tened securely to a bent shank. This tool can be had of hardware dealers, to Fig 44 Scraper for cleaning and whom it is known repairing trees. as a box -scraper. Aside from removing the loose bark from the trunks of trees, this tool is very useful in cutting out and removing all diseased spots upon the bodies or in the crotches. The wounds resulting from the barking of trees may be trimmed down to fresh tissue by such a tool, and all spots injured by bark borers, spots of pear-blight, patches of canker, and the like, may be cut away, and the wounded surfaces are thereafter covered with Bordeaux mix- ture or paint. In the scraping of trees, it is al- ways advisable to take away every particle of wounded and diseased tissue, unless it extends deep into the wood. When the object is to simply take away the rough and loose bark, the tree should not Thf Principles of Fruit-growing. Fig. 45. A young trunk girdled by a label wire. be scraped down to the quick • that is, only the loose ex- terior portion should be re moved. Girdled trees, and gird- ling.— Trees which are girdled should have the injured parts pared down to live tissue and the wounded surface then covered with an antiseptic, dressing. It is also advis- able to bind up the girdle with some material like grafting -wax, which will keep the wood moist and thereby allow the ascent of the sap ; for the sap rises in the tree through the young, soft wood, and not between the wood and the bark. The bark is formed over the wound by the sap which is re- distributed through the tree after it has been elaborated in the leaves ; that is, the reparative tissue is formed by elaborated sap which is on its downward course. If the woody tissue is kept soft and fresh, the tree may continue to live for yoars, but there will be a deposition Repairing Girdled Trees. 289 of woody matter above the girdle, whilst the por- tion below will not increase in diameter. This is well known to all observing fruit-growers. Fig. 45 shows a deposit of woody matter above a girdle caused by a label wire. After awhile the younger wood is apt to become hard and dry, pre- venting the upward passage of nourishment taken in by the roots, and the tree then starves to death ; or, as in the case of the young tree shown in Fig. 45, the top may become so heavy that the plant breaks off at the point of constriction. It is, therefore, evident that it is very necessary that the orchardist give careful attention to his label wires, to prevent them from doing great injury. It is always best to take the labels from young trees when they are set, and to depend upon a map record for the names of the varieties. Or, if the label is left upon the tree, it is best to hang it upon one of the minor limbs, rather than upon the trunk. In adjusting the label wire to the tree, it is important that only the ends of the wire be twisted together, allowing thereby a large loop in which the limb may expand. The label may be held tightly to the limb by simply pinching the wires together with the fingers. Trees which are freshly girdled in the growing time of spring may be expected to heal over before the season is over, if the girdled zone is not more than four or five inches wide, and if the surface of the wood, as already explained, is kept perfectl.v fresh. It is generally best, however, if no connec- tion of bark remains, to bridge over the girdle by 290 The Principles of Fruit -growing. cions. These cions are of the same kind as those which are used for ordinary grafting. The edges of the girdle are pared down to fresh wood, and the eions are cut two or three inches longer than the width of the girdle. They are whittled to a wedge shape upon either end, and these ends are inserted between the bark and the wood upon the upper and lower sides of the girdle. They should be so numerous as to almost touch each other en- tirely around the tree. After they are inserted, a strip of cloth should be bound tightly upon the bark over their ends, and the whole girdle should then be waxed over. It is a good plan to pour melted wax over the work, allowing it to run in between the cions and cover the edges of the bark and the exposed surface of wood. The congestion of the parts of the plant im- mediately above the girdle shows that those parts are overfed ; that is, they receive nutriment at the expense of the portions below the girdle. It would seem, therefore, that girdling might be made to in- crease the size and hasten the maturity of fruit which is borne beyond the girdle ; and such is known to be the case. The girdling of grapes is a common practice in some regions. The girdled portions are entirely removed in the next annual pruning, and enough of the growing portion is left below the girdle to maintain the roots and trunk. It will be seen, therefore, that the liability of in- jury to the vine is all a question of how much is left below the girdle and how much above it. Girdling of Trees. 291 Careful vineyardists are able to continue the prac- tice year after year without apparent injury to the vine. The girdling is done when the grapes are about the size of peas, and a section of bark about an inch wide is entirely removed from the cane. A gain in earliness of a week to ten days may be secured by the process, but it is commonly believed that the quality of the better grapes is injured. As a matter of practice, only the very earliest varieties of grapes are girdled or ringed for commercial pur- poses ; and it is doubtful if the practice is to be commended. Apples and other fruit trees are sometimes ringed to set them into bearing. "Many orchards develop a habit of redundant wood -bearing, and these are often thrown into fruiting by some check to the trees, as seeding down, girdling, and the like. Probably every orchardist has observed that the at- tacks of borers sometimes cause trees to bear. Tt is an old maxim that checking growth induces fruit- fulness. This is the explanation of the fact that driving nails into plum and peach trees sometimes sets the trees to bearing, and also of the similar in- fluence exerted by a label wire which has cut into the bark, or of a partial break in a branch. Girdling or ringing to set trees into bearing is an old and well- known practice. It is not to be advised as a general resort, but I should not hesitate to employ it upon one or two of the minor branches of an unprofitable tree for the purpose of determining if the tree needs a check. I saw a Baldwin tree this year in which 292 The Principles of Fruit-growing. two large limbs had been -girdled last year, and these limbs were bending with fruit whilst the remaining branches and the adjacent trees were barren. Gir- dling may generally be done with safety in spring, when the leaves are putting out. A ring of bark two or three inches wide may be removed clear to the wood, and entirely encircling the limb. I have heard of excellent results following the simple ringing of trees, which consists in severing the bark— but remov- ing none of it — completely around the tree with a sharp knife, in spring. These are, of course, only incidental operations, to be employed with caution, and then only upon branches of less importance. Their value is wholly one of experiment, to aid the owner in determining what fundamental treatment the orchard probably needs."* Pruning and heading -in.— The subject of pruning cannot be understood until the fundamental principles of the practice are clearly apprehended. It is, there- fore, well -nigh useless to state any general rules or precepts for the pruning of trees in a work like the present. It is only necessary to say that a heavy pruning upsets the habit of the tree, and generally sets it into the heavy production of wood for a time. The only proper pruning is one which is applied in something like the same proportion every year, and which begins the very year in which the plants are put into the ground. Trees which are alternately neglected and heavily pruned are kept in a condition *Bull. 102, Cornell Exp. Sta., 519 (Oct., 1895). A fuller discussion of ring- ing may be found in "The Pruning- Book." Heading -in Fruit Trees. 293 of unrest which is apt to be fatal to the best produc- tiveness. The question of heading -in of trees is one which is commonly misunderstood, and upon which there is the greatest demand for information. It is impossible to give any dogmatic statements as to whether the operation shall be practiced or not. There are two or three considerations which the grower should chiefly bear in mind, which may help him to think out the problem for himself. In the first place, it is largely a question of the type of training which the grower prefers : that is, every good fruit-grower will set before himself a certain ideal type or form of tree, and he will bend all his energies uniformly and consecutively to the working out of this idea through- out all the years of the plantation. If his ideal is for trees which shall have round and dense heads, then he will, of course, head -in the stock from year to year ; if, however, he sets for himself the ideal of a tree with the natural form and open head, he will not head -in, as a rule. Whichever purpose the grower sets in his mind should be worked out sys- tematically and logically from first to last. The other factor which chiefly determines the question of heading -in is that of redundant growth whilst the plants are young. As a rule, young trees grow more thrifty and upright than old ones do, and the grower should, therefore, not be misled into thinking that his trees will keep up their present pace after they have come into maturity and bearing. Kieffer pears, for example, make a very tall and narrow 294 The Principles of Fruit-growing. growth for the first two or three years, but when the bearing time arrives, this enormous growth is checked and the tree spreads. However, in such cases, it may be advisable to head -in the tree for a time, or until the period of maturity begins to ar- rive. It should always be borne in mind, however, that this heading -in is not the fundamental corrective of the difficulty ; in fact, it rather augments it. It is a question, therefore, if it is not better to pre- vent redundant growth by withholding tillage and fertilizers, rather than to produce it and then to take it off. Winter preparations. — In winter, plants are exposed to injuries of wind, snow, water, ice, mice, rabbits, and the like. Before the season closes, the farmer should see that young trees stand stiff and straight, and in order to keep them rigid and to afford good surface drainage, it is sometimes well (especially with newly set trees in cold climates) to bank up the trees with earth to the height of six or eight inches. In making the bank, the workman should be cau- tioned not to leave holes, from which the earth is taken, close about the tree, for the water is likely to stand in them, and it may do harm. In small -fruits, grapes and nursery stock, it is often advisable to plow a furrow to the plants, upon either side, in the fall. Care should be taken to provide for top drain- age if the conformation of the land is such as to hold surface water. A word should be said respecting the protection of trees from mice and other vermin. Mice and rab- Injuries from Rabbits and Mice. 295 bits injure trees chiefly in cold winters, when the amount of green food is scarce. They are apt to be especially bad in new countries. The best preventive of injuries from mice is to see that there is no mate- rial, as dead grass or weeds, close to the base of the tree, in which the rodents can nest. If the litter is not taken away, it should at least be tramped down tightly before winter sets in. The best preventive of injury by rabbits is not to have the rabbits. If the brush piles and old fence -rows, in which the animals harbor, are cleaned away, there will commonly be little trouble ; and, at all events, a smart boy who is fond of hunting will ordinarily solve the question without help.* If mice are very serious, it may be advisable to put cylinders of wire netting about the trees, as al- ready recommended. Rolls of birch bark are some- times used in regions where the paper -birch grows. It should be borne in mind, however, that such cov- ers for the bodies of trees interfere with clean culture about the base of the tree, and they are apt to afford a most excellent place for the lodgment of borers and other insects. The common notion that wire screens, and tarred paper, and mounds of ashes, and the like, prevent borers from working, is unfounded, and is, in fact, likely to be the very opposite of the truth; for a wire screen, which soon fills with grass and litter, is a most inviting place for the congregation of insect life. 'Various washes and other devices for preventing the injuries by mice, rabbits and gophers may be found in "The Horticulturist's Rule-Book." 296 The Principles of Fruit-growing. Depredations of stock and birds. — Injuries of trees can be prevented in sheep pastures and hog pastures by giving the animals plenty to eat and especially plenty to drink. They are very likely to gnaw the trees for the moisture which they secure. If, how- ever, the animals begin to injure the -trees, the only recourse is either to take them out or build wide racks about the trunks ; but any sort of rack or fence about the tree prevents the proper care of the tree. The incursions of birds upon cherries and small- fruits can usually be prevented by planting in suffi- cient quantity that the birds may get their fill with- out ruining the plantation. Cherry orchards may sometimes be protected by planting a number of trees of very early sweet cherries around the outside of the plantation. These will be sufficient to satisfy the birds. In some cases, however, it is impossible to save the fruit unless fire-arms are used ; but it is usually sufficient to fire blank cartridges a few times to scare the birds away, and thereby obviate the necessity of killing them. Small trees and garden plats of small fruits may also be protected from birds by means of netting which is now manufactured in this country for that purpose. Troop reports* as follows upon an experi- ment in this direction : "The past season we had several varieties of the Russian cherries which were fruiting for the first time, and wishing to test the practicability of cov- *James Troop, Bull. 53, Indiana Exp. Sta. 125 (1894). Protection from Birds. 297 ering trees as a protection from birds, we procured from the American Net and Twine Co., of Boston, Mass., several hundred square yards of bird netting, and a part of the trees were covered with this just before the fruit began to ripen. "Three trees of the Bessarabian variety were standing together in the same row, all well loaded with early fruit. Two of these were covered with the netting and the third left exposed. When the fruit on the covered trees was ready to pick, the exposed tree was completely stripped of every cherry, thus showing what the result would have been to the others had they not been protected. The question has often been asked : Will it pay ? "As already stated, the trees were young, having been set but six years. Each tree bore a half bushel or more of fine fruit this year, which sold for eight to ten cents per quart. The trees were of the round- headed type, about ten feet high, so that the labor involved in covering was comparatively slight. The amount of netting required for each tree was about seventy -five square yards, which cost four cents per square yard. As soon, however, as the fruit from these early trees was gathered, the netting was trans- ferred to later varieties, and the same process re- peated. So that when the experiment was completed the account stood as follows : To 75 yds. netting at 4 cents. .$3.00 $3.00 By 16 qts. of cherries at lOcts. .$1.60 " 18 " " " "8 " . 1.44 $3.04 298 The Principles of Fruit-growing. "It will be seen that in this experiment the ac- counts nearly balanced at the end or the first year. With careful handling this netting will last ten years or more ; so that the question — will it pay to use it? — will depend largely upon circumstances. Judg- ing from our own experience the past season, where, in . testing varieties of fruits, it becomes absolutely necessary that the fruit should remain on the tree until fully ripe, there seems to be no question about the expediency of covering the trees." Top -graft ing bearing trees.* — One of the important factors in the secondary care of an apple orchard is the grafting over of old trees or of worthless varieties. It is often asked if it will pay to graft trees after they are fifteen or twenty years old. The answer depends entirely upon how profitable the trees are in their present condition. If they are bringing in no return, then nothing can be lost if they are grafted ; and if the trees are strong and healthy, there is no reason why much should not be gained. If the operation of top -grafting is properly done, the trees ought to be completely changed over to a new variety in three or four years. It should be said, however, that the careful fruit-grower will find out whether his trees are to be profitable or not long before they reach the age of fifteen years. Trees which have arrived at that age before the owner has found out whether they are useful or not, are those which advertise an indifference or *For advice respecting the top-working of youug trees, see pages 2IM, 235. The Thinning of Fruit. 299 neglect of the owner. Even with apple trees, the orchardist should be able to tell within ten or twelve years after they are set whether the trees are likely to be profitable or not, and if there are strong indications that the varieties are unsuited to his needs the sooner they are grafted over the better. In grafting over the top of an old apple tree, it should be borne in mind that it is at the best a harsh operation, and that the top should be replaced as quickly as possible. In other words, the effort should be made to graft only limbs of com- paratively small size (say not more than an inch and a half in diameter, and preferably less), and to set very many cions, even if some of them need to be cut out after two or three years. The setting of so many cions is somewhat expensive, but the orchardist should be able to do the work himself. Finally, it should not be expected that an old tree which is remodeled by top -grafting shall be of as good and handy shape as one which has been grown right from the start. (See Figs. 127, 128, 129, "The Nursery -Book," third ed.) Thinning the fruit. — The thinning of fruit for the purpose of improving that which remains is a prac- tice which is always advised, but comparatively sel- dom followed. It has been demonstrated time and time again that no work in connection with a fruit plantation pays better than this thinning. It not only results in a much finer product, but it is also a means of destroying the insect -infested and dis- eased specimens, and of saving the energies and vir 300 The Principles of Fruit-growing. tality of the tree. Persons complain that the thin- ning of fruit is expensive and laborious, and this is true ; but it is a fair question if there is anything worth the having of which the same may not be said. If the operation pays, then there is no excuse for not performing it. It should be considered, also, that the fruit must all be picked sooner or later, and it really does not cost very much more to pick it early in the season than to pick it late ; in fact, much fruit which is not worth picking in the fall might have been eminently worth the labor if the trees had been thinned in the early summer. There are two general methods of thinning fruits: One is a matter of pruning, by means of which the superfluous branches, or even the fruit -spurs them- selves, are removed ; the other is the direct picking of the redundant fruits. There is no reason in the nature of things why trees should not bear every year; but the formation of the fruit -spur is usually such as to preclude the production of fruit upon the same spur every year. The philosophy of the thin- ning of fruit, therefore, is that one spur shall bear one year, and another spur the next. This means that when fruit is thinned, it should be the object to remove it wholly from some spurs in order that they may produce fruit -buds for the following year. In those regions where certain fruits are systemati- cally thinned, the crop is obtained with great uni- formity every year. This is especially true of peaches along the Michigan lake shore, and in other places where this important fruit is well cared for. There Experiment in Thinning Apples. 301 is no reason why the same should not be said of other kinds of fruits, and for every fruit region. There have been no long -continued and system- atic experiments upon the thinning of fruits in this country. One of the best investigations which has yet been undertaken was in connection with the State Experiment Station at Geneva, New York, under the direction of S. A. Beach in 1896. These experiments were made upon full-grown apple trees, and the following extract* details the methods and the 'results : "Trees of the same variety, as nearly alike in all respects as could be found, were paired for com- parison, one of each pair being thinned, the other left unthinned. Three ways of thinning were tried : "First.— All wormy, knotty, or otherwise inferior fruit was removed, and all clusters thinned to one fruit. "Second. — Same as first, and remaining fruit thinned so that the apples were not less than four inches apart.

"The sixteen trees which are included in the experiment belong to three varieties, namely : Rhode Island Greening, Baldwin, and Hubbardston. The Baldwins were most heavily loaded last season, and gave the most marked results in favor of thinning. "With the first method Baldwin, thinned, gave *Proc. W. New York Hort. Soc., 1897, p. 75. 302 The Principles of Fruit-growing. 16 per cent less fruit, but about 10 per cent more No. 1 fruit than did the unthinned Baldwin. With the second method Baldwin, thinned, gave 26 per cent less fruit and about 22 per cent more No. 1 fruit than did the corresponding trees which were not thinned. "With the third method, Hubbardston gave 25 per cent less fruit, but about 17 per cent more No. 1 fruit than did the unthinned Hubbardston. "The Greenings were very heavily loaded in 1895, and in 1896 they bore a good crop, but were not overburdened, and needed comparatively little thin- ning. They were thinned according to the second method, and gave 6 per cent more fruit and about 10 per cent more first -class fruit than the trees did which were not thinned. "In all these tests the picked fruit gave about one bushel of culls where the fruit was thinned, to three bushels where it was not thinned. Where the fruit was thinned the "drops" were fewer and con- siderably better, and in all grades the fruit was clearly superior in size and color to fruit of the same grade which was not thinned. The first grade in- cluded no apples less than two and one -half inches in diameter, and the proportion which measured two and one -half inches was a great deal larger where the fruit was thinned than where it was not, so that No. 2 apples from trees which were thinned were much superior to the No. 2 fruit from trees not thinned Mr. Wilson [in whose orchard the tests were made] estimates that the fruit from the tree* which were Thinning Small -fruits, 303 thinned would generally bring 10 per cent to 15 per cent more in market than the same grade from trees which were not thinned. According to these results, the second method of thinning is enough superior to the first to more than pay for the extra work involved. The second and third methods can- uot well be compared from the data now at hand." Maynard reports* experiments in thinning apples and plums, from which there were marked gains. To thin "full -sized" apple trees cost from 35 to 48 cents. In plums, "a distinct advantage gained by thinning is the appreciable decrease in the ravages of fungous diseases, and to a small extent, of insect pests. This is especially noticeable in the case of monilia, or brown fruit -rot, which often ruins the peach or plum crop in wet seasons, while the speci- mens of fruit attacked by the curculio were largely removed in thinning." Tests have been made in a small way in the thinning of small fruits by clipping off the ends of the clusters. Halsted reportst as follows upon such a test: "Some experiments were made here [New Jersey Experiment Station] last year with currants, by removing the lower half of the flower clusters with a pair of scissors. It is a well-known fact that only a few of the berries of any cluster usually mature, and the free end of the stem becomes dead before the fruit is ripe. By the removal of this *Bu]l. 44, Mass. Hatch Exp. Sta. (1897). t Garden and Forest, iii. 19 (Jan. 8, 1890); also, Kept. N. J. F.xp. SU. 18«», 304 The Principles of Fruit-growing. portion before the flowers upon it have opened, it was hoped that there might be a larger and better fruit produced upon the remaining portion of the cluster. "In the experiment, alternate bushes in a row were treated with the scissors, and in passing it may be said that this method of thinning can be done rapidly. When the fruit was ripe, the whole product from an average bush, of the clipped and of the undipped plants, was picked and spread out upon tables. Judges ignorant of what had been done were then called in to inspect the results. No one failed to notice at once the difference, and all pro- nounced in favor of the fruit that had been treated. The berries were larger and of more nearly uniform size and ripeness. Two hundred berries were next removed from the uncut clusters, and it required thirty-five clusters to furnish this number. They weighed, clear of all stems, one hundred and fifty- two grams. The same number, furnished by thirty clipped clusters, weighed one hundred and sixty -three grams. These results show that there were about 15 per cent more berries to the cluster upon the cut plants than upon the ordinary ones, and that these berries were about 7 per cent heavier. The question of quality was only determined by tasting, but there was no doubt in the minds of the judges that the thinned clusters bore fruit of the finest flavor. Like all other fruit, currants sell somewhat upon their appearance, and there is no mistake that from the uniform size and ripeness of the fruit and Thinning Small -fruits. 305 the absence of dead tips on the stems, the clipped clusters were much the more attractive." Experiments made at the Cornell Station* with raspberries and blackberries failed, however, to give such specific results: " To test the feasibility of thinning berries, rows of Cuthbert raspberry and Early Cluster blackberry were thinned by clipping off the tips of most of the clusters, and also by reducing the number of clusters, especially in the raspberry. The result was not encouraging, for the eye could detect no increase of size in the berries on thinned plants, and as the principal object was to increase the size and attractiveness of the fruit, it seems to have failed of its purpose. It should be said, however, that the season was favorable for berries, and the crop was very fine. In a very dry season, or with varieties much inclined to overbear, the result might be different. In general, however, the thinning can be managed well enough and much more cheaply by regulating the amount of bearing wood at the annual spring pruning." The thinning of tree fruits is done in essentially the same way in which the fruits are picked; that is, the fruits are picked off by hand, and are then dropped onto the ground, where they may either be allowed to lie, or, if they are infested with insects or disease, may be raked up and burned. It is customary to thin the fruits as soon as the dangers of spring frosts and other early accidents are past, *Fred W. Card, Bull. 57, Cornell Exp. Sta. (1893). U 306 The Principles of Fruit-growing. but before they have become of sufficient size to be a tax upon the tree. Peaches are generally thinned when they are about the size of a small hickory nut (that is, about the size of the end of one's thumb), and apples are thinned from that size until they are twice or sometimes even thrice as large. Various devices have been suggested for the thinning of fruit, but they are all impracticable, because they do not discriminate between good and poor fruit, because they do not leave the fruit well distributed over the branches, and because they are very likely to break off the spurs. Some of the implements figured in Chapter VIII. may be used in special cases. It really requires more discrimination and judgment to thin fruit properly than it does to pick it. In the thinning of peaches it is a good rule to allow none of the fruits to hang closer than four or six inches of each other. This means that in years of very heavy setting, fully two -thirds of all the fruits are to be picked off in June. In many parts of the country this thinning is systematically done, and it has in all such cases come to be regarded as an indispensable element in successful fruit-growing. No reliable estimates of the cost of thinning fruit can be given, because so much depends upon the form and pruning of the tree and the amount of fruit to be removed. The result is also greatly influenced by the character of the workmen and the price paid for labor. Full grown peach trees may be thinned for 15 to 50 cents each. Apple trees twenty -five and thirty years old have been well thinned for 30 to 80 cents each. Maps for Fruit -grounds. 307 MAPS AND RECORDS. One of the most annoying parts of fruit-growing is keeping track of the various varieties which in- evitably accumulate in plantations to which the owner gives much loving" thought. The best means is a systematic plat, map or diagram of the plantation, in which every tree or every row of small -fruits is given a number. It is well to designate the rows in orchards by letters, and then to number each tree in the row, beginning with number one ; or, some prefer to number all the trees in the plantation con- secutively. It is an ideal plan for the grower to devote a large blank -book or record to each plan- tation, entering the plan of the area in the earlier pages, and then recording the yield of each tree or each row on consecutive pages which are devoted to the different years. Such a book would be to the orchard what the Babcock test is to the dairy, — a means of determining the unprofitable individuals. If such a record were kept, it would not be many vt -.-Irs before the orchardist would be experimenting with a goodly number of his trees in order to de- termine how to make them as productive as the In -si ones are. Of labels there are endless devices, but it must be remembered that no label can be expected to last in good condition more than six or eight years. For temporary or annual plants, where little horse work is done, the commercial garden stakes, 12x1% in., are excellent. These cost, when painted and made of 308 The Principles of Fruit-growing. soft, clear pine, $4 to $5 per thousand. For a more permanent stake label, one cut from clear pine, 2 ft. long, 3% hi. wide, 1% in. thick, and sawed to a point, is one of the best. These are given two thin coats of white lead,, care being taken not to pile them upon their faces until thoroughly dry, to avoid a rough surface for the pencil. The record may be made by a large soft pencil, like a carpenter's pencil, or by a brush and black paint ; but for all annual crops the pencil will be found more serviceable. At the end of the season, or when the record becomes dim, a thin shaving is planed off the face of the label, it is repainted, and used again. The label is thick enough to allow of many annual dressings, while the lower portion is not reduced, and it there- fore lasts for many years and is strong enough to resist the shocks of cultivator or whippletrees. For ornamental bushes this large label is too conspicu- ous, and for this purpose a pine label 1% in. wide, % in. thick, and 18 or 20 in. long is excellent. The lower half is soaked in a strong solution of sulphate of iron (copperas), and, after drying, in lime water, to preserve it. A great variety of labels has been recommended for trees, but it is doubtful if we have yet found the ideal label, although some of those which are here described seem to satisfy most needs. Many people like zinc labels (No. 11, Fig. 46), cut in narrow strips from a sheet of the metal. The record is made upon the zinc with a soft lead pencil, and the label is then wound about a branch. Very often the record is Various Labels. 309 indistinct upon the zinc label, but the chief fault is its inconspicuousness. It requires much searching to find a ziuc label upon a large tree, and this objection holds with almost every practicable tree label which has been introduced, even with the three or four -inch pine labels which are common in the market. Patent /inc. and copper labels, which are cut from very thin metal, so that the record can be made .by the impres- sions of a sharp point or style, have been tried at Cornell. "These pretty and so-called indestructible labels are furnished with an eyelet through which the wire passes. We were much pleased with these labels when we put them upon our orchard trees one fall ; but the next spring we found that the metal had broken away from the eyelets, and nothing remained of them but a hole hung upon a wire."* The Cornell label is the device shown at No. 3, in the illustration (Fig. 46). "We buy the pine 'pack- age label,' which is used by nurserymen, and which is 6 in. long and 1% in. wide. These labels cost, painted, $1.30 per thousand. These are wired with stiff, heavy, galvanized wire, much like that used for pail bales, and not less than eighteen inches is used upon each label. Hooks are turned in the ends of the wires before the labels are taken to the field. A pail of pure white lead, well thinned with oil, is taken to the field with the labels. The record is made with a very soft pencil, the label is dipped into the paint, the wire is placed about a conspic- *Bull. 61, Cornell Exp. Sta. 341. Pig. 46. Various types of tree labels. See explanation, ou pages 308-311. Various Labels. 311 uous limb, and the hooks are joined with a pair of pliers. The paint at first almost completely obscures the writing, but some of it drips off and the re- mainder dries in, so that the record becomes bright and the soft pencil marks are indelibly preserved, while the label remains white. If the paint is brushed on, the soft writing will be blurred. If in the future the wood becomes gray, the label can be brightened by immersing it in a pot of white lead, without removing it from the tree. The large loop of wire allows of the growth of the branch, and the label hangs so low that it can be seen at a glance. The heavy, stiff wire insures the safety of the label against boys and workmen. It cannot be removed without a pair of pincers. The label is large enough to allow of a complete record of the name of the variety, the place of purchase, age, and other matters; and it is readily found."* The various labels which are shown in Fig. 40. are as follows : 1, 2, German labels, made of glazed earthenware, with the name colored blue and sunken. Strong copper wire, coiled, to allow of the growth of the limb, holds the label to the tree. 3, Cornell label, described above. 4, double wooden label, consisting of two common wooden labels fas- tened together. The name is written upon the outside of the double label, as in any other label, but it is also written on the inside to insure permanence.

INJURIES BY COLD AND RAIN. There are two distinct types of injuries to fruit plants by cold, — true winter -killing (or the injury of the tree or buds when perfectly dormant by the low temperature of winter time), and the killing of the growing or swelling parts by the "cold snaps" or frosts of late spring and early fall. Either subject is too large for full elaboration in the present vol- ume, and therefore only some of the most obvious and usual aspects of the subjects are here considered. Winter -killing of the wood.— There are three fac- tors which chiefly appeal to the fruit-grower in th« winter-killing of trees, — positive cold, very dry or very wet soil, and heaving of the land by frost. The subject of "dry freezing" has already been dis- cussed to some extent in Chapter I. The heaving of the land is prevented by drainage, by proper methods of tillage, and by the judicious use of cover crops. The degree of cold may be somewhat modi- fied, as we have already found, by exercising judg- ment in the selection of site and exposure, and by the careful employment of wind-breaks. Yet, winter- 314 The Principles of Fruit-growing. killing must always be one of the gravest risks which the fruit-grower assumes when he undertakes the business. Winter -in jury to the trees or plants themselves usually appears in the form of splits or long checks in the trunks, or in the outright death of the ends of the branches, or even of the entire plant. For the splits lengthwise the trunk, the proper treatment is to pare off the dead and loosened bark to the "quick" just as soon as the bark begins to spread, and to cover the surface of the wound (and the cleft) with Bordeaux mixture or paint.* The proper treatment for frozen -back trees must be determined for each particular case; but it should be borne in mind that the injured portion is no longer of any use to the plant, whilst it may be a positive detriment by accelerating the evaporation of moisture. The best treatment for plants seriously injured upon the extremities is to cut them back very heavily. This severe heading -in — sometimes to the extent of three or four feet— removes the driest and weakest portions, and concentrates the energy of the tree into a comparatively small area of top. Heavy pruning always tends towards the production of wood, and this wood production is probably never more needed than in winter -injured trees, for it tends to renew the vitality of the tree. The philosophy of this becomes apparent upon a moment's reflec- tion. The browned and injured wood can never re- *The general subject of treating and repairing injured trews is fully dis- cussed, with illustrations, in "The Pruning-Rook." Treating Frozen Trees. 315 gain its former usefulness. New tissue must be developed as quickly as possible, in order to carry forward and to maintain the vegetative energies. This new tissue is laid on over the old, and the old thereby quickly becomes sealed in, so to speak, and removed from the agencies of decay. Every observant fruit-grower knows that if a tree which is severely winter -injured in limb and trunk were to bear even a partial crop of fruit in the coming sea- son, it would very likely die outright. If, however, all its energies were directed to the development of new tissue, the injury would soon be overgrown. The injured wood, like the heartwood of the tree, is soon removed from active participation in the vital processes. It therefore follows that the danger re- sulting from the browning or blackening of the wood by winter- injury depends very much upon the sub- sequent treatment of the trees. Fig. 48 shows the body of a young plum tree (in longitudinal and cross-wise sections) which was frozen black in the severe winter of 1895-6. It was heavily pruned in the spring of 1896, and in the fall had made a ring of bright new wood, which was amply sufficient to maintain the tree in perfect health for a long life. This appearance is common in nursery stock the year following a very hard winter, but such trees may not be permanently injured. There are instances in which this heavy heading- back seems to do more harm than good. These are cases in which the entire tree is almost uniformly in- jured, and the plant se^ms to need the stimulus of The Principles of Fruit -groiving. all its buds to bring out the feeble life which is still left to it ; but these cases are comparatively rare. It is probable that the greater number of reported in- stances of death due to heavy pruning of winter -injured trees are of such trees as would have died under any treatment. Winter -killed plants often retain suffi- cient vitality to enable them to leaf out- or to bloom, and sometimes even to be- gin growth, but when the stored vital- ity of the tissues is exhausted the plant perishes. This explains the phenomenon, which, after a bad winter, nearly always puzzles the inobservant fruit-grower, of trees starting into feeble growth and then suddenly dying when warm and dry weather approaches. Winter -killing of the fruit- buds. — In severe winters, the entire fruit -spur (in the spur- fruits, as apples, pears, plums and apricots) may be killed outright, but the commoner case is the death of the bud only. The bud may be entirely killed, in which case it soon turns brown through- out its entire diameter and the flower never opens : or only the pistil (the central organ, which ripens into the fruit) may be killed, in which case the flower may Fig. 48. Showing the new tissue formed around winter-injured wood. Winter -killing of Buds. 317 open and appear to be perfectly normal to the un- critical observer. The latter case is common in peaches and apricots. Fig. 49 illustrates the point. The flower at the right was unin- jured by the winter, and the pistil is seen, grown full length, at 1. In the other flower, the pistil, at 2, is dead. We know that this pistil was killed before the bud be- gan to swell, because it retains the small size which it must have had in the dormant bud. If it had been killed after the bud had Fig. 49. Normal apricot flower swollen, it would have appeared j^^o? wtS. ' as a much larger and a more or less crumpled or withered organ, as in 6, Fig. 52, page 320. A true fruit -bud is one in which the flower, or cluster of flowers, is present in miniature. (See "The Pruning -Book" for full discussion of fruit -buds.) This flower occupies the very center of the bud, and is sur- rounded by dense lay- ers of scales. A healthy bud is nor- mally green in the central part in cross -section. When the bud has been killed by the winter, in the usual manner, this central portion of the a 6 c Fig. 50.

Fig. 50 shows a fresh or live bud at a, and a killed bud at 6 and c. When only the pistil is killed, un- trained eyes may not detect the injury. The general run of examinations made of buds by farmers, to de- termine if there is winter -in jury, are of little conse- Showing structure of peach buds. quence. Except in very pronounced instances, the only reliable examination is one which is made under a dissecting microscope.

Sta., 1890, U'JT; also Ai Killing of Fruit -buds. 319 maturely developed buds. At a, Fig. 51, is shown a section through a bud, as found in January of an ordinary winter. The bud scales overlap each other closely, and inclose all thfi more tender parts that go to make up the blossom y^\ The pistil, that is to de- velop into the fruit, occupies the center, and is a somewhat flask-shaped body, while next to it are the floral parts, to which the stamens are attached. The stamens are small and almost colorless. Turning now to />, which represents a section through a half -opened bud, it will be seen that there is very little change in the pistil. This portion is the last to be affected by the modifying circumstances; but the scales are • wide open at the top, the stamens have enlarged re- markably, and it is to their development that much of the opening out of the scales is due. It is only necessary, at this time, to call attention to the fact that the stamens are organs for the production of pol- len, and this flower -dust is only used to stimulate the receptive pistil into new life. And, while the growth of the pistil is mostly after fertili/ntion, it is, however, true that during the time when it is receptive to the pollen it is most susceptible to cold and other condi- tions, and it is the portion of a peach bud that first manifests injury from frost or other exposure. "The inference is natural that cold can get into an open bud much more easily than a closed one, but we need to look back of the visible differences to the vital conditions. Vegetable tissues in active condition are less able to bear extremes of heat and cold than those in a quiescent state. A seed, for 320 Thf Principles of Fruit-growing. example, that is dormant will bear the conditions without injury that would kill it if germination was taking place. The delicate structure at the center of a flower not only needs to be kept, by the infold- ing bud scales, from being exposed to the elements, but, most of all, it requires that an inactive condi- tion within itself shall prevail.' A well -prepared bud is like a seed, and becomes most sus- ceptible to sudden changes only when it is unfolding or preparing to grow. It is not so much the opening of the bud scales as the grow- ing condition within, result- ing in the unfolding, that permits the dangerous results. "The pistil is the part first to show that the flower bud is blasted and worthless. The green, fresh appearance is replaced by brownness, the former plump, upright organ becomes shriveled and drooping. In Fig. 52, at a, is shown a healthy pistil, as seen in a live bud. To the right, at 6, is another pistil that has recently been killed, and was turning brown. The stamens are the next -to change, in the same way, from the normal color to the brown of death. The other less vital organs of the blossom finally die, and after a short time become a dark and worthless substance. If the Fig. 52. Live and killed pi and Killing of Fruit -buds. 321 bud is not opened, it may require a longitudinal cut of the knife to determine the exact condition, but last winter an ordinary pinch of the swollen bud Fig. 5:5. Showing, respectively, swollen buds of apricot, peach, Japan plum, and pear, all of which were uninjured by 14° of frost. was enough to demonstrate that all was blasted and worthless within." Injuries to the swelling buds. — A great amount of mischief is done by "cold snaps" after the buds have begun to swell, and yet the disaster is not so easily wrought,— at least not in the north,— as is commonly supposed. Even the buds of the tenderer fruits ma3r endure very sharp freezes after they have begun to 322 The Principles of Fruit -growing. show color. In the spring of 1897, some observa- tions were made upon this point at Cornell. Buds of apricots, peaches, plums and pears (as shown in Fig. 53) had swollen to three or four times their normal size. The pink color of the apricot buds was distinctly visible, and the tips of the anthers could be seen in the Japan plums by looking down squarely upon the buds. In this condition, the buds endured with no injury the following temperatures, as taken by self -registering thermometers hung in the trees (very light snow on the ground and a wind blowing all night): Lowest temperature. April 20, Apricot, peach, Japan plum, pear 18° April 21, Apricot, peach, pear 19° — Japan plum 18° It will be seen that these buds endured 14 degrees of frost without injury. Upon the coldest morning, the buds were stiff from freezing, and in some in- stances the backs and tips of some of the petals were permanently discolored. The buds swelled with the freezing, but returned to their previous size when thawed out, but they looked as if withered for several days, — or until active expansion began. It is very probable that buds cannot endure this degree of cold further south. Injuries to flowers and growing parts. — When the flowers have fully expanded, a comparatively light frost will destroy them. This is shown in the fact that a very slight elevation in a blackberry or straw- Frost Injury to Flowers. 323 Kig. r>t. A strawberry nnbbin, due to frost. berry patch is often sufficient to avert injury. The pistils seem to suffer first. A strawberry nubbin is shown in Fig. 54. The top of the berry (or the bot- tom, as it hangs) is flattened and deformed. This is generally due to the freezing of the upper pis- tils in the flower, as it stood erect. Nubbins are sometimes the result of imperfect pollination, but in such cases the deformity is more apt to be upon the sides than upon the top, for the top pistils are the ones which are very likely to be fertilized by insects. A similar case is reported upon blackberries at Cornell.* "The only serious ac- cident which is known to injure the blackberry crop in this state is frost ; and in most cases the injury is unavoidable, even though the grower has warning of its approach. In the six crops which we have grown in our patches here, only this year have we suf ered from frost, and even this year, when the cold wave was unusually late and severe, only the lowest places suffered seri- ously. Drawings of blackberry flowers were made upon the spot, two or three days after the frost, and Fig. 55. Blackberry flower: full size. 'Bull. 99, Cornell Exp.

Inside the five white petals or leaves are seen the numerous sprawling stamens or so-called male organs, each one bearing an enlargement or anther on the end, inside which the pollen is borne. In the center of the flower is the head or cluster of pistils or so-called fe- male organs, each of which ripens into one of the Httle grains which go to make up the blackberry. The frost killed these organs, so that the center of the flower- bore only a small black column of dead pistils (see Fig. 56). Now and then, one or more of these pistils in the head escaped, and developed into a fruit-grain, so that the berry became a nubbin. Fig. 57 shows the dead and aborted fruits at picking time. At the top of the picture are some fruits (N, N,) in which one or two grains or drupes are full grown, whilst the Fig. 57. Blackberry fruits ruined by frost rest of the berry failed to develop. Frost Injury to Floivers. 325 Upon the 8th of May, 1897, a temperature of 27° (5 degrees of frost) was recorded by self -registering thermometers hung in fruit trees at Cornell, but no injury resulted. At this time, all the petals had dropped from apricot flowers, but the calyx ring had not yet fallen from the young fruits ; peach flowers were in full bloom, but their fertilization had mostly taken place ; •Japan plum flowers were just dropping, and pear flowers were open, but not yet fully fertilized. Young fruits of apples and pears may sometimes re- cover from a severe freeze and make per- fect specimens.

A com- mon effect of very late frosts is to leave a distinct russet zone upon the fruit. This zone marks the position of the frost upon the young fruit. Apples and pears are usually still erect when these frosts occur, and the dew, — which, when frozen, is frost, — probably settles in a ring or belt near the top of the fruit or midway down it. The exact position jind conformation of this deposit of dew are, of course, determined by the shape, position and exposure of tho fruit. Figs. 58 and 59 show the frost zones on Fig. 59.

Amongst the most serious results of very late frosts in the north are the injuries to vineyards.

Grape shoots ruined by the freeze of May, 1895. The extent to which the vines had grown is shown by Fig. 63 (page 330). The spray upon the left shows the grapes of normal size (that is, from unin- jured shoots) as they looked in midsummer. The central spray shows grapes which were produced from the second crop of flowers, which appeared after the Treating Frozen Vines. 329 vines began to recuperate. The right-hand spray shows a cluster of flowers appearing upon a belated shoot. Of course, only the clusters of the largest size, as shown at the left, ripened into good fruit. In proceeding to treat frozen vines, like those de- scribed, it must first of all be borne in mind that the injured parts are of no further use to the plants, and, as we have seen, they are very apt to weaken the plant by causing it to lose much of its moisture. The rational procedure, therefore, is to strip off all the frozen shoots soon after the disaster, so as to allow the energies of the plant to divert themselves to the production of new shoots. When the injured parts are soft and small, it is customary to remove them by pulling them off, rather than by cutting them off. In vineyards which are well pruned, the cost of stripping ought not to exceed one dollar an acre. What is an injurious degree of cold?* — To this oft -asked question there can be no specific answer, because so much depends upon the latitude, the time of year and the condition of the plants. Hammont gives the following " table of temperatures at which the following plants are liable to receive injury from frosts, compiled from information received from horticulturists, orchardists and gardeners through- out the entire Pacific coast. "The temperatures given are as nearly as pos- sible those in contact with the plant itself. * A discussion of acclimatization, and other problems of climate and plants may be found in "The Survival of the Unlike." t W.

We have already seen (page 322) that at Ithaca, New York, apricots, peaches and other fruits were able to endure a temperature of 18°, even when the buds were well swollen. In respect to the variations in the effects of winter temperatures, McCluer* writes from the Illinois Experiment Sta- tion as follows : "Here, we ordinarily think of 14° or 15° below zero as fatal to the peach crop, and as we often have a lower temperature than that but few peaches are planted. During the winter of 1894-5 the ther- mometer several times ranged below 20, and once sank to 25 below zero, and yet only half the peach buds were killed, and the trees produced a good crop the season following. Last winter, with a minimum temperature of only 5° below zero, fully one -third of the peach buds were killed. I do not know just what conditions made the buds more hardy one season than another ; neither do I know why part of the buds on a tree should be more hardy than the rest. Even in the axil of the same leaf one bud may be killed and the other live. "Other organic substances show the same differ- ences. In a half-bushel basket of potatoes exposed to the cold in a cellar, I have often found frozen tubers scattered through the basket and the rest not frozen. In the blossom -buds of the cherry and plum one or more may often be found killed, while the rest have escaped. *G. W. McCluer, Garden and Forest, ix. 209 (May 20, 1896) Effects of Rain at Blooming -time. 333 "When we first began to spray our peach trees to prevent the fruit from rotting, the Bordeaux mixture used was not properly prepared, and as a consequence a large part of the leaves on the sprayed trees fell off prematurely. The next spring it was found that there was a larger proportion of live buds on the trees from which the leaves had fallen than on the rest of the same variety. My explana- tion at the time was that the buds become less hardy in proportion as they are more developed. We know this is true in the spring. The question at once arises, at what stage in the development of a bud is it the most hardy, and how can we best control that development? This seems to me a promising field for careful study." The effect of rain upon blossoms. — It is perfectly well known that the weather conditions in which plants are growing may profoundly affect the fecundity of the flowers. In the forcing of winter vegetables, for example, it is of the greatest impor- tance to keep the house dry and warm when polli- nation is to be effected, and better results — both in the amount of pollen produced, and in the ease with which it is discharged from the anthers — are commonly obtained in bright sunshine. (See, also, page 227.) It is very probable that if the flowers of fruit plants were to be kept constantly wet, very little pollination would take place. It is probable, also, that dashing rains at blossoming time wash away much of the pollen, but it is doubtful if enough of it would be lost in such passing storms 334 The Principles of Fruit-growing. to seriously reduce the crop of fruit. The most disastnms storms are probably those milder ones of long duration, and which are accompanied by a low temperature. Not only may such weather tend to prevent the discharge of pollen, but it prohibits the work of insects. It must be admitted that the above remarks are inferences. We have almost no exact knowledge as to the effect of rain storms upon the setting of fruit. A few small studies have so far been made in this country, and these are now quoted. Beach and Fairchild* report experiments in ap- plying continuous sprays to pears and grapes. "On May 16 two Mount Vernon pear trees, apparently of equal vigor, standing within one hundred feet of each other, were selected. Into one was thrust the Vermorel nozzle, with its broad, fine spray. The tree was about twenty -five feet high, and the spray from the nozzle did not entirely cover it ; in fact, the original design, soon abandoned, was to wet only one -half of the tree, and leave the other half dry. At the inauguration of the experiment, only a few blossoms had opened upon either tree, and, as no insects had been busy about the fruit trees, owing to the cold weather immediately preceding, no risk from previous pollination was run. The water was turned on at noon of May 16, and kept running (except from 10 A. M. of the 21st, to 10 A. M. of the 23d, during ai almost constant rain-storm, pre- * Eleventh Ann. Rep. N. Y.

The total length of time in which the tree was kept wet was two hundred and nineteen hours, or nine days and three hours. "On May 17, after the tree had been under the spray twenty -four hours, an examination was made of the stigmas of many of the flowers, and they were found to be dusted with pollen, although no insects had been seen about the tree. Pollen was taken from fresh anthers on the 21st (the fifth day), and placed in weak sugar solution, to test its ger- minative power. It proved to be perfectly capable of germination. The flowers at this time presented a curious appearance. The anthers of the innermost stamens were plump and of their normal pink color, while the outermost ones were swollen and decayed, and contained many disintegrated pollen grains, and a few that had evidently been induced to germinate by the excess of moisture. The power of the male elements to withstand long -continued moisture was apparently great, for at the close of the experiment, after the rain had ceased, many anthers opened and shed an abundance of pollen, while the anthers of flowers on adjacent trees had withered and fallen sev- eral days previously. After turning off the water , on the 25th, an examination with a hand lens was made of flowers on both the side nearest to and that far- thest from the spray, with the following result : "Of four hundred and three flowers counted on the side receiving the most water, one hundred and three were possessed of plump anthers and apparently 336 The Principles of Fruit-growing. normal stigmas. Of three hundred and three flowers upon the dryer side, only three were still fresh and capable of fertilization. The effect of the water in retarding the development of the flowers was strik- ingly illustrated. * ********** "Although, as mentioned above, after the spray had been removed many flowers with perfect anthers and pistils remained capable, presumably, of self-pol- lination, only one fruit, bearing three seeds, was borne by the tree. This was produced about midway between that half more heavily wet down and that more nearly dry. The unsprayed tree produced a fair crop of normal fruit. "Two vines situated near each other were selected for an experiment. One was left untreated for a check, the other was sprayed for twelve nights and days. Since the Duchess came into blossom later than was anticipated, the sprayed vine was under treatment a week before the check began to bloom. Unavoidably the spray was discontinued before either of the vines was out of blossom. It will, therefore, be seen that the twelve days' treatment did not cover the entire period that the vines were in bloom. "The first apparent effect of the spray was to re- tard the opening of the grape blossoms four days, as compared with the blossoming of the check vine. This effect was noticeable during the blossoming period, and the treated vine continued in blossom at least four days longer than the check. Retarding the blossoming period, however, had no perceptible Rain at Blossoming -time. 337 influence on the ripening of the fruit, for the fruit of both vines ripened at the same time. * * * "A microscopic examination, made after the spray had been running eleven days, failed to disclose any perceptible injury to the pollen. The pollen germs were not disintegrated, nor had they germinated, and no difference could be detected between them and pollen grains from the check vine. By its peculiar structure the grape blossom is well adapted to with- stand protracted rains without injury to the sexual organs. As shown by one of the writers in a re- cent paper (see page 230), many grapes pollenize their own stigmas before the blossoms open enough to allow the entrance of outside pollen, and the Duchess belongs to this class. Although self-pollina- tion is thus insured, efficient fertilization does not always follow, and consequently in some varieties it does not result in the production of fruit. Such grapes are able to set fruit only when supplied with outside pollen. It is, therefore, probable that with grapes of this class, e. , Caswell Geared Sprayer. 4, Wagon Outfit (Morrill & Morley). 5, Mounted Barrel Sprayer, fi, Eureka Tank Outfit (Morrill & Morley).

The syringe and bucket purnps are very efficient for work upon a small scale, and especially when it is desired to be extra thorough. The greatest difficulty with the bucket pump is that the amount of material which can be carried is very small. The power sprayers (those which work from the wheel of the vehicle) are useful for vineyards, dwarf pears and low- growing plants ; but, as a rule, they are not adapted to large orchard trees, because enough liquid cannot be thrown whilst the machine is passing a tree to thoroughly spray it. For very large areas and very tall trees (as street trees) steam- power sprayers are coming into use. 7. The farmer should know what he icants to kill before he begins to spray. — It is common to find a man who is going at spraying with enthusiasm, but who cannot explain a single definite object which he has in view. He simply knows upon general principles that spraying is useful. To such a man, spraying is spraying, whether he uses Paris green, or Bordeaux, or both, or neither one; and his results are about equal to his knowledge. There is no longer an excuse for such ignorance, for all the lead- ing insects and fungi have received more or less exact treatment in the publications of the experiment stations. The state of knowledge is far in advance of the state of practice. Many fruit-growers demand such elementary instruction as this: The arsenites (Paris green and London purple) are used to kill all larvae or worms, and all those When to Spray. 369 insects which chew the leaves or shoots, — such as the codliii-rnoth, bud -moth, canker-worm, potato - beetle, tent -caterpillar, and the like, kerosene emul- sion* is used for scale -insects and plant -lice. Bor- deaux mixture and ammoniacal carbonate of copper are used to prevent the attacks of fungous parasites, as apple -scab, leaf -blight of the pear, quince and plum, potato -blight, and such like. Bordeaux is the better all-round fungicide, but the copper carbonate solution! does not discolor the fruit, and may there- fore be used if very late sprayings are necessary. The times and seasons of spraying depend entirely upon the enemies which it is desired to reach, and upon the weather. 8. The time to spray must be determined for each jHuiicular case. — The grower himself must decide when and how often to spray, because he should * KEROSENE EMULSION.

Dilute with 9 or 10 gallons of water. For same purposes as the Bordeaux mixture. 370 The Principles of Fruit-growing. know what enemies he desires to reach. If he has the bud -moth, he should spray with the first swell- ing of the buds, and if he has the plum -scale he should spray in the winter. But, leaving the special insects aside, it is safe to say that for the two staple enemies — the apple -scab and the codlin-moth — at least two sprayings should be given. It is not yet clearly proved that spraj'ing when the tree is dormant has any appreciable ef- fect in destroying the apple- scab fungus. As a general state- ment one may say, spray twice upon ap- ples and pears, once just as the fruit-buds break open but be- fore the flowers ex- pand (Fig. 76), and again just as the last blossoms fall. In both cases, use a combination of Bordeaux mix- ture and Paris green. The first spraying is for the scab fungus in particular, and for this the Bordeaux is used ; but the Paris green will most likely be of service in destroying various leaf -eating insects. The second spraying is for the codlin-moth in particular, and for this the Paris green is used ; but the Bor- deaux mixture will still be needed for the apple -scab and other fungi. Whether or not it is necessary to spray again will depend largely upon the season. Fig. 76. Showing when apple tre?s ready for the first spraying Stock Solutions. 371 The operator must watch matters closely, and spra.y when he needs to do so, or when he is in doubt. Two spraj'ings are sufficient for the codlin-moth, and three are generally sufficient for the apple -scab. These two sprayings constitute the insurance which lias been mentioned ; thereafter, the grower will be jible to see more definitely what is needed. These remarks illustrate the nature of the questions which the fruit-grower must consider. At any time when the tree is in growth, Paris green or London purple should be used with lime, or, better, with Bordeaux mixture, to prevent injury to the foliage. One pound of Paris green to two hundred gallons of water is the most serviceable gen- eral foi-mula for that material ; and to this a pound or two of lime may be added. A pound of Paris green (or London purple) may be added to two hun- dred gallons of Bordeaux mixture. If the Paris green • is made into a paste with a little water, it mixes bet- ter in the barrel. 9. Prepare stock solutions for the Bordeaux mix- lure* rather than f<> »ie used on peach foliage, apply it at one-half the ordinary strength. 372 The Principles of Fruit-growing. called for by the formula.— The sulfate of copper may be put into solution and kept in this condition in- definitely, ready for use. A simple method is to dissolve forty or fifty pounds of sulfate in as many gallons of water, pulverizing the material and hang- ing it in a coffee -sack in the top of the barrel. A gallon of water, therefore, means a pound of sulfate. The lime may also be slaked and kept in readiness for use. Slake it into the creamy condi- tion familiar to masons, cover lightly with water, and then close the box or vessel to prevent the water from evaporating. When making the Bordeaux mixture, pour the requisite quantity of the stock solution of sulfate of copper into the barrel, and then dilute with four or five times the quantity of water. Now add the lime, and then add enough water to satisfy the formula. If the ferrocyanide test is used, place a spoonful of the mixture in a saucer or plate, and add a drop of the test solu- tion. If a red color appears, the mixture needs more lime. If the test solution is added directly to a tank or barrel of the mixture, the color re- action is apt to be lost in the mass. An excess of lime ensures the safety of the mixture. 10. How can one tell if soluble arsenic is jtrrsatf in Paris green "I — It is the soluble arsenic which burns the foliage. This is present in London pur- ple, but good Paris green should have little of it. Farmers are always asking how they can determine if Paris green contains soluble arsenic. This may be determined by the use of the sulfur test. This Testing Paris Green. 373 test consists in adding sulfuret of hydrogen to a solution of the poison, when, if arsenic is pres- ent, a yellow precipitate (or sediment) will be thrown down. In a bottle holding" five or six ounces, place a quarter of a teaspoonful of Paris green. Add water until the bottle is nearly full ; shake well, and then allow the material to settle. The clear liquid which remains on top will contain what soluble arsenic may be present. Carefully turn off this clear liquid into a long, slender bottle, or test-tube, add two or three drops of muriatic or sulfuric acid, then add a tablespoonful or more of the solution of sulfuret of hydrogen. If any arsenic is present in the clear liquid, a yellow discoloration will at once appear, and if the liquid is allowed to stand for a few minutes, patches or grains of a sand -like material will settle to the bottom. This yellow precipitate is sulfide of arsenic. If very little soluble arsenic is present, the sulfuret solution should be warm when used, for the reaction is then more delicate. The sulfuret is easily made by anyone who has had even an elementary instruction in chemistry, by add- ing sulfuric acid to iron pyrites. This sulfuretted hydrogen is not a commercial preparation, but it is present in all sulfur mineral water, and the water sometimes gives the test. One can make sure of the presence of this material, for its odor is strong and offensive. It is the odor of spoiled eggs. If mineral water is used, it should be strong and fresh, and about equal in quantity 374 The Principles of Fruit-growing. to the arsenic solution ; and even then only a faint amber discoloration may appear, because of the small amount of sulfur in the water. The min- eral water test, therefore, is practically out of the question. This test of arsenic determines only the fact that soluble arsenic is or is not present. It does not determine how much soluble arsenic there may be ; although the greater or less amount of the yellow color on precipitation will afford a compara- tive idea of the amount present in any two or more samples. It has already been advised to use lime with Paris green or London purple for the purpose of taking up the soluble arsenic, by the formation of arsenite of lime. If this is done, or if the Bor- deaux mixture is used with the arsenit.es, it will not matter if the poison contains soluble arsenic. 11. Ho ic can one determine if Pa rift green is pure f — It sometimes happens that material which is obtained as Paris green contains no arsenic. Chrome green may be sold instead. If the material is pure Paris green, it will quickly and completely dissolve in common strong ammonia, giving a beautiful, rich, dark blue, clear liquid, whilst any of the compounds which would ordinarily be substituted for Paris green on account of their color and texture, will not be- have in this manner in ammonia. Any insoluble residue is impurity. Chrome green will not dissolve in ammonia. 12. What becomes of the arsenic when it ftilh upon Arsenic in the Soil. 375 the soilf — With the action of the rains and the fall- ing of the leaves, most of the arsenic which is applied to trees finally reaches the soil. What then becomes of it? If lime has been used with the spray, the arsenic will be insoluble when it falls upon the soil. It is possible that the organic acids in the soil, and also carbonic acid, may dissolve some of the arsenic, but it would be almost surely made immediately insoluble again by combination with lime or other soil constituents. If soluble arsenic is placed on the soil, it probably almost immediately goes into insoluble combinations, and remains where it was placed unless slightly washed down by mere mechan- ical means. Now, some plants appear to have the power to take up very minute quantities of arsenic and still thrive — probably so minute that the nicest chemical test can scarcely discover it, — but any appre- ciable quantity of soluble arsenic in the soil quickly destroys the roots. If, therefore, the grass and other plants under sprayed trees continue to live, there need be no fear that the arsenic will injure the soil. A study of the destination of arsenic which has been applied to the soil in the form of Paris green was made at the Cornell Station (Bulletin 101), from which the following conclusions were drawn: "The gist of the whole matter then, if we may generalize from these tests, is that the arsenites do not leach from the soil. They remain where they fall, the same as sand does, and are carried down only when there are crevices or other openings in the soil, and they then go down as insoluble compounds, and to 376 The Principles of Fruit-growing. a slight extent, by the mere mechanical action of the water. It is really remarkable that sand was such a perfect filter as to hold the great quantity of arsenic above a depth of three inches for over four months. If the soil in either experiment had been a homogenous subsoil, where the sun could not have cracked or checked it, it is fair to conclude that no arsenic could have penetrated it."* Summary. — The fruit-grower may desire to have a very brief epitome of some of the cardinal sug- gestions touching spraying : 1. Spraying is only one of several means or opera- tions which the pornologist must master if he aspires to the greatest and most uniform success. Other fundamentally important requisites are tilling, fertil- izing and pruning. 2. Spraying is not necessary to successful results every year, but inasmuch as the farmer cannot fore- tell the need of the operation, he should spray as a matter of insurance. 3. Spraying is almost sure to be of some benefit every year, particularly upon apple, pear, plum and quince trees, and upon grape vines. 4. Spraying is of little consequence unless care- fully and honestly done. The spray must actually reach every point which it is intended to protect. 5. Prepare for the year's campaign during the previous winter, by reading the last teachings, and * For another discussion of this subject, and of the destination of copper in the soil, see Lodeman, "The Spraying of Plants," 231-237. Summary. 377 by completing pumps and appliances. Give particular attention to a convenient wagon outfit. 6. The Bordeaux mixture need not be made up at each using in the exact numbers of the formula. The copper sulfate may be permanently dissolved in water and the lime may be slaked. When the mix- ture is prepared, the stock solution of vitriol is di- luted, the lime added, and the tank filled to the required amount. 7. Spraying is of small account unless the opera- tor understands precisely what he sprays for. 8. The time to spray is when the operation is needed to protect the plant. This will vary, there- fore, with every season and every different pest. In general, apples and pears need spraying twice, first when the fruit -buds open, but before the flowers expand, and again when the blossoms fall. 9. The presence of soluble arsenic in Paris green may be determined by a test with sulfuret of hy- drogen. 10. Pure Paris green dissolves in ammonia, giv- ing a rich, deep blue liquid. NOTE.— Home-made arsenites of lime and soda are now used in some regions Either can be used with Bordeaux mixture. When used with water, it is safer to add freshly slaked lime. Arsenite of lime is made by boiling one pound of white arsenic in two to four quarts of water until it is dissolved, then use this arsenic solution to slake two pounds of good lime, adding water if necessary to slake it ; when slaked, add water enough to make two gallons of this stock mixture. This may be kept in a tight vessel and used as desired. Thoroughly stir the material before using. For most insects one quart of the above to forty gallons of water will be sufficient.

CHAPTER VIII. HARVEST I * 'G- AND MARKETIXU FRUIT. ALTHOUGH the management of the business or commercial side of fruit-growing — the importance of which is urged in the first chapter — is very largely a matter of personal temperament, nevertheless a few general remarks by way of suggestion may be given to the subject. The business part of fruit- growing is chiefly concerned with the broad subject of marketing the fruit, which may be considered under the four heads of picking, packing, storing and shipping. The actual selling of the product is an enterprise which belongs rather to the merchant- man than to the fruit-grower. PICKING FRUITS. When to pick. — Just when and now the fruit should be picked for best market results depends very largely upon the species or variety of fruit, and greatly, also, upon the distance to which it is to be shipped. The closer and better the market, the riper the fruit should be when it is taken from the plant. If one is fortunate enough to have a special or personal market, delivering the fruit to (378) When Fruit is Fit to Pick. 379 the consumer direct, then he can hope to retain this market only by sending in the products in the very finest dessert condition. Such consumers are generally willing to pay a sufficient extra price for the advantage of having the fruit taken from the plant when it is in its highest state of edible quality. Most serious mistakes are constantly made in the picking of blackberries, for example. It is ordinarily considered that when the berries are black they are ripe, but such is not the case. They are fully ripe only when they shake from the bushes readily, and when they are soft and free from sharp acidity. In this condition blackberries can be handled direct to the consumers in the local market which is only a few miles away ; but they could not be shipped by rail. The strawberry is ordinarily picked for market when only a portion of the berry is really ripe, and when the organic acids are still too sharp and ' austere for the des- sert. A strawberry which has a green or white tip is not yet in fit condition to pick, if one is ex- pecting to reach a really good market. With the tree -fruits, it may be said that in general the samples keep longest when they are picked greenest, but they suffer thereby in point of quality. There are no well-marked lines between greenness or immaturity, ripeness or full maturity, and over maturity and decay. The one stage passes into the other insensibly, and it is a part of the normal chemical history of the fruit that it should begin an incipient breaking down and disorganize- 380 The Principles of Fruit -growing. tion of tissue as soon as the ripening process is thoroughly complete. It will be seen, therefore, that the riper the fruit, the more nearly it approaches this period of disorganization, and the sooner the breaking down of the tissues may be expected to begin. When the fruit is picked very green, how- ever, this period of natural disorganization is com- paratively remote. On the other hand, fruits which are picked very green are not yet arrived at their most edible stage, and unless they are kept in the most favorable conditions, they are very likely to shrivel and to become unmarketable. In the case of apples, it is generally best to pick them, if they are to be stored or exported, just as they have arrived at their full size and when they have attained only a part of their full color. Overripe or fully ripe fruits must be sent to the market at once, or else they must be kept in artificial cold storage in order to thoroughly stop the chemical processes within the fruit, and when they are taken from storage they are very likely to soon decay. Apples which are picked slightly green, however, generally continue to keep well after being taken from cold storage. This was demonstrated at the World's Fair at Chicago, at which New York apples taken from cold storage remained upon the shelves in good condition for several weeks.* Pears, on the other hand, nearly always lose quality by fully ripening upon the tree. The cells of the fruit fill up with gritty mineral matter, much * Annals Hort. for 1893, 67. Ripening of Pears. 381 to the detriment of texture. It is ordinarily con- sidered that the best time to pick a pear of any variety is just as soon as it reaches its full size and before it has begun to color. In most varie- ties, this stage is pretty well indicated by the facil- ity with which the fruit stem parts from the spur. The pear is taken in the hollow of the hand and turned up ; if the stem snaps off from the spur at its point of articulation, the fruit is generally considered to be ripe enough to pick. The pears are then ripened under cover. The best place in which to ripen them is a rathei: cool but dry room, like a loft or a chamber. Here they are piled upon the floor or upon racks, and they should not lie, for the best results, more than three or four pears deep. If they are piled too deep, the lower ones are likel}r to be indented by the weight of those above them. The room should be kept fairly close. If there is too much circulation of air, and if the temperature is high, the pears ripen too quickly, and often shrivel. A Bartlett pear, when properly picked and handled, ordinarily requires a full week in which to ripen up to its best quality, and the ripening process may often be continued consider- ably longer than this by picking the fruit early and keeping it cool. Kieffers, especially if grown in the north, seem to ripen best if they are stored in bulk, like beans, two or three feet deep, or even in barrels, and the ripening process is ordinarily two to three weeks long. If they are given this long time in which to mature, the quality may be 382 The Principles of Fruit- growing. expected to be very much better than it is in the general run of samples. A peach is fit to pick when it is full grown and has begun to develop its characteristic color. Peaches and apricots do not ordinarily color up well after they are picked, although plums usually will do so, especially the Japanese plums, which may be picked very green and yet develop a high color. It is very difficult to describe .that period of ma- turity at which a peach is ready for picking. An experienced picker will take the fruit softly in his hand and press the ball of his thumb very lightly upon the side, and if the fruit has a somewhat springy feeling, it is ready to take off the tree. This pressure is never sufficient to leave any mark upon the fruit. Pinching a peach will almost always spoil it. If the peach is too green, it will feel hard and stone -like. If it is too soft, it will simply indent, and will not have the elastic feeling which is mentioned. In the case of cherries and plums, it is very important that the fruits be picked just before they have reached their condition of most edible quality. This is largely because the fruit-rot fun- gus is very likely to destroy the fruits at the time of their ripening, especially upon those varieties which are particularly subject to the disorder. Amongst plums, the Lombard is one of the most seriously attacked ; and amongst cherries, nearly all the white -fleshed ones, like Governor Wood and Napoleon, are greatly subject to injury. If the Rot of Cherries. 383 weather at picking time gives promise of being (dose and warm or muggy, then it is exceedingly important that the fruit should be picked earh'. In sweet cherries, a delay of a few hours will some- times result in the loss of an entire crop from the fruit -rot fungus. Cherries and plums should always be picked, if possible, when they are perfectly dry. This is especially true of the sweet cherries. If they are picked when they are wet, and put into boxes or baskets in this condition, they will be almost certain to decay before reaching the market, unless the weather remains very cool. This fruit -rot fungus is very serious upon many stone fruits. In cherries, "the losses from this dis- ease which have come under my observation are invariably the result of letting the fruit hang on the trees till ripe, and then the rot is very active; but cherries should be picked a few days before ripe, before they soften, and then the rot does not seriously affect them. An illustration of this point, which is a most important one, was brought to my notice the present season. The last week of June, in eastern New York, was very hot and close, with showers every day or two. The cherries were then ripening, and the conditions were favorable for the rot to spread. In one orchard, from which several tons of cherries were shipped that week, there was not more than one hundred and fifty pounds destroyed by the rot, while in another or- chard a few miles distant at least ten tons of the same varieties were ruined on the trees. In the first 384 The Principles of Fruit-growing. orchard the fruit was picked before it had ripened, and all that was fit was taken off as soon as the trees dried off after a shower ; in the other or- chard it was left till nearly ripe, and one -half to two -thirds of the crop was lost before the fruit could be picked. So rapid is the work of this fungus at this period, that the owner of the orchard told me that he lost three tons of -one variety in one night. It might be added that the orchard first mentioned was a much stronger one, as it was in cultivation, while the last had been in sod for years, and the general debility and neglect of the trees made them good subjects for the attacks of rot or any other disease."* How to pick. — In picking the soft fruits, like cher- ries and plums, the operator grasps the stem and not the fruit itself. In this way he does not remove the delicate bloom, and does not injure the fruit when pulling it from the spur. In the case of grapes, it is likewise very important, especially in those which have a heavy bloom, that the picker should not grasp the bunch itself, but should take the cluster by the stem and snip it off with shears (which are made for the purpose). In the case of peaches and apricots, this precaution, of course, need not be taken, because the stem does not naturally adhere to the fruit ; but the operator must be very careful, when picking these fruits, not to grasp them too tightly, otherwise he will bruise them and cause *G. H. Powell, Bull. 98, Cornell Exp. Sta. 410. Leave the Stems On. 385 them to become discolored. The picker must always bear in mind that every evidence of fruits having been touched by the hands detracts from their market value. Strawberries should always be picked with the stems on. A berry which has the hull pulled out is not fit for the market. The picker should grasp the stem itself and pinch it off between the thumb and the finger. Upon all fruits which grow on a distinct pedicel or stem, this stem should be allowed to remain. Pears which have the stems pulled out or broken in two are never first-class fruits, no matter how good and uniform the specimens otherwise may be. This is even true of apples when they are put up for the finest dessert trade ; but as they are ordinarily handled, very little attention is paid to leaving the stems on. Leaving the stems on is vital to the handling of plums and cherries, not only because the market demands it, but because the fruit will be very likely to rot if the stems are pulled out, and they will not pack so snugly, and will not stand the transportation so well. The stems of cherries, plums and currants, and the hulls of strawberries, serve a most useful purpose in hold- ing the fruits in place in the box or basket, and in taking up the slack from settling or shrinkage. A word may be expected in respect to the ex- act methods of handling fruit in the field. It is only in rare cases that fruit should be sent to the market in the packages in which the pickers place it ; that is, it will need to be sorted from these 386 The Principles of Fruit-growing. packages into others, and this sorting should be done in a cool shed or packing room. In the pick- Fig. 77. Dundee berry st ing of small fruits, various kinds of trays or stands are used. In strawberries, it is important that these stands should have legs, so that when the package is set down it will not crush the berries, and neither will it be so likely to tip over. Such stands are handy for grapes, or for any kind of berry fruits as well. Fig. 77 shows a type of berry- stand which is largely used in parts of New York for the picking of raspberries and blackberries. This stand holds six one -quart boxes, and a tier is easily stacked upon another, one tier or layer of stands breaking joints with those above and Fig. 78. Berry-tray made of slice iron, with band-iron handle. Berry - stands . 387 below. Other types of berry -stands are shown in Figs. 78, 79 and 80. In the picking of tree -fruits, it is ordinarily best to use a basket and not a bag, for in spite of all one can do, the fruit is bruised when r4, is thrown into a bag which is slung over the shoulder. In the picking of peaches, it is customary to pick in something like a Climax basket, or better still, in the old-fashioned tall, round -top peck baskets, such as are standards in New Jersey and other places. These baskets are held at about one'* Fig. SO. Tniy for berry boxes. middle by dropping them into a hoop which is held upon the person by a strap running over the shoulder and under one arm (Fig. 81). This allows the picker the free use of both arms, and obviates the necessity of his being obliged to stretch or stoop to deposit the fruit after he has picked it. The baskets are filled about level full, all the fruits which are ripe enough for picking being saved in- discriminately. The basket is then set in the shade alongside the tree from which the fruit was taken, and at intervals a wagon or cart collects the bas- kets and takes them to the packing -room, where The Principles of Fruit-growing. the fruit is sorted, graded and packed. In the picking of apples, the best method is ordinarily to use a half -bushel, round -bottomed splint (not woven) basket which has a swinging handle. If this basket V Fig. 81. Picking peaches. is lined on the .inside with thick cloth or burlaps, it will answer the purpose all the better. This basket is provided with a strong wire hook, that can be hung upon a limb, allowing the picker to Baskets and Wagons. 389 have both hands free. There are various special practices to facilitate apple -picking, which are not proper subjects for discussion in a general fruit- book. There are various appliances which may be used in the field to facilitate the picking of fruit, some of which may be briefly mentioned. In the first place, the fruit picker should provide himself with an ample supply of crates or baskets, or whatever other receptacle may be used in the field. These receptacles should be strong and durable, so that they may be used year after year ; this is espe- cially true of the baskets and crates which are used for the picking of the heavier fruits, like pears, apples and grapes. It is generally advisable to take the fruits to the packing house in the very baskets or boxes in which they are placed from the tree, thereby avoiding unnecessary handling of the fruit. In the case of winter apples, however, it is sometimes ad- missible to carefully pour the apples from the round- bottomed baskets, into which they are picked, into bushel baskets, or sometimes into crates such as are used for potatoes. In any case it is always advis- able, in the best quality of fruit, to have all these baskets or crates lined with burlaps. The best wagons for use in orchards are those which are of the platform style, with low and very broad -tired wheels, and the platform extending over the wheels. Such wagons are not only capable of carrying a very large load, but do not cut up the ground ; they are easily drawn and managed, and 390 The Principles of Fruit-growing. they escape the limbs in low orchards. It is desir- able that the front wheels should turn under the platform, in order that the wagon may be turned at sharp angles. The practice of loading apples and other fruits into a wagon box in bulk cannot be too strongly deprecated. It is only admissible when the apples are of low quality, and are fit only for sale as second and third grades, or for manufacture into cider, evaporated stock, or other products. The styles of ladders to be used must depend directly upon the height of the trees. In old apple orchards, it is nearly always essential to have long and light ladders, with a sharp or peaked top, which can be run directly up into the top of the tree and find lodgment against the branches. Extension lad- ders are also used, but they are usually more cum- bersome and more difficult to manage than the light pointed -topped implement which is here mentioned. In most other orchards, however, a step-ladder of the ordinary pattern, but perhaps somewhat taller (running from ten to even twelve feet high), is all that will be required. This ladder should have a flat top, and also a movable shelf upon its back, where baskets may be placed. The facility of pick- ing fruit is very much increased if the trees have been well trained and pruned. Dwarf pears should rarely reach a height of more than twelve or fifteen feet ; and if pear and apple trees are planted suffi- ciently far apart, and are kept open at the base, the pickers can reach most of the fruit by climbing. In the picking of apples and pears, there is nothing fig. 8'eutsche Landwirtschaftliche Presse, xxiv., No. 7, Jan. 27, 1807. 412 The Principles of Fruit-growing. This danger has now become actual through the flooding of the German market with fresh American apples. It is, e. g., a fact, that during this winter the demand for apples in Berlin is being supplied with the American product, and others are scarcely offered or not desired. This condition, and the dangers to the German fruit industry arising there- from, are set forth in a praiseworthy manner in a small pamphlet by B. L. Kiihne-Rixdorf (Berlin, 1897). This pamphlet also points out the means 'by which we in Germany, by following to some extent the practical American — in relation to the growing of a. few good marketable varieties of fruits, rigidly sort- ing them, and packing and shipping in proper pack- ages— can successfully meet the dangers alluded to. "The suggestions made by the author of the pamphlet are as follows : "1. The fast transportation of fresh German fruit at low rates on the part of the railroads. "2. The cultivation of a few valuable varieties. "3. The rigid sorting of fruit destined to be eaten in the fresh state. "4. The rational conversion of the less valuable fruit into imperishable marketable products, as fruit juices, cider, marmalade, jelly, steamed fruit, dried fruit, and fruit wines. "5. The general introduction of light, cheap and strong packing cases of standard size. "6. The proper packing of the fresh fruit. "7. The training of scientific and practical special- ists in fruit culture. Wrapping in Paper. 413 "8. The planting of large, rationally conceived and intensively cultivated fruit plantations, for the imme- diate supply of the German market. "The present conditions prove that past methods for advancing the German fruit industry have not been productive of the desired results, and it is high time that all who have the welfare of this industry at heart unite on the basis suggested; then and not until then will the conditions improve through the in- creased home production of fruit, if but sufficient to cover home consumption; we shall be able to suc- cessfully meet foreign competition, and this done, it will be possible to conquer for the German product a prominent place in the markets of the world." Fruits which are intended for the dessert may often be put into the consumer's hands in very excel- lent condition by wrapping them in soft grocer's paper, of the kind which is ordinarily called tea paper ; or, when the product is especially choice, and the grower has a large quantity, it may pay him to use a grade of tissue paper. There are many middle- men who practice this careful packing, and growers may often imitate them with profit. It is needless to say that all wrapped samples of fruit reach the consumer in perfect condition, and he may depend upon their excellence and uniformity as he could upon a case of eggs. With pears or apples, the in- side of the keg or barrel is lined with newspapers, and each fruit is individually wrapped in soft ma- nilla paper. Such fruits may be expected to carry thousands of miles without perceptible injury. When 414 The Principles of Fruit-growing. opened, their aroma is such that no well-bred con- sumer can resist the temptation of a high price. Ordinary fruits, however, are not worth this care. It is important that all fruit should be packed very snug, especially that which is to be shipped any distance in barrels or other large packages. Fruit which is slack when it reaches the market is nearly always injured, and sells as second or third quality product. This slacking or shaking Jn barrels may be prevented by using fruits which are not over ripe, by careful attention to grading, so that all the specimens are of uniform maturity, by keeping the product cool after it is packed, and especially by placing the fruits in the package by hand. Barrels of apples and pears should ordinarily be filled about an inch above the chine and the fruit should be pressed in with a screw or lever press until the head comes into place. If the fruits are wrapped in paper, or if the package is lined with several thicknesses of paper, the spring of the paper itself will take up the slack and will keep the fruit in place ; and in such cases it is not necessary to apply heavy pressure in the heading -up of the barrel. Upon the best brands of fruit, a trade -mark is often important. Some neat pictorial design, with the name of the grower and a statement to the ef- fect that the fruit is guaranteed to be as repre- sented, attracts the eye of the purchaser and gives him confidence in the article ; but to put a trade- mark upon fruit of indifferent or even of ordinary quality is little more than a joke. If a man uses Thf Growing of the Fruit. 415 a trade -mark, he must expect, of course, to handle his own produce, or at least to see that it reaches the market under his own name. The fruit, buyers who travel through the country for apples and other produce ordinarily pay little attention to the trade- mark of the grower, but put their own mark upon the package. If one really grows a good quality of fruit, it will commonly pay him to give his farm some neat and attractive name, which can go onto the labels. In short, every effort should be made to put up the produce in a finished manner, as the best grades of manufactured produce are now packed and delivered to the consumer. Very much .of the success of any fruit upon the market depends upon how it is grown as well as how it is handled. There may even be a difference in the salableness of samples of fruit which are to all appearances alike. It is now pretty well demon- strated, for example, that apples from trees which have been thoroughly sprayed and well tilled are better keepers than those of similar size and appear- ance which are grown upon neglected trees. When fruits are to be shipped to any distance, it is par- ticularly important that the tillage and general care of the fruit plantation should have been the best. Packages. — It is well nigh useless to make any general remarks upon the packages which are used for fruits, because so much depends upon the par- ticular grade of the fruit and upon the way in which it is shipped and handled ; very much also depends upon the demands of the given market 416 The Principles of Fruit-growing. It is an excellent plan for the fruit-grower to visit markets in advance of the ripening of his crop, and to determine just what style of package his market will most appreciate. When fruits are pooled, or shipped through exchanges or unions, it is imperative that a uniform style of package should be used; but when a man handles fruit solely upon his own ac- count, and has a fine or superior quality, he can often advertise his product by a unique package, or at least by one that is unlike those in most common use. Such a package singles him out from his neighbors, and answers as a trade -mark for his product. The writer has known profitable returns to be got from fruit which was shipped in colored baskets. A dye was made of aniline, and the bas- kets were dipped into the kettle (being handled with a pitchfork), and fruit which was no better than the ordinary run brought from two to five cents a bas- ket more than that packed in the ordinary white package. This will not often succeed, however, but this instance is given simply to show that a package which is somewhat out of the usual run may be a desirable one for a man to use upon particular oc- casions. In all the finest fruits the grower should use nothing but a gift package, that is, one which is given away with the fruit when it is sold. This in- sures a clean and dainty package, and the pur- chaser is not bothered with the thought of returning it. In fruits which are to reach a good market, a package which has been used once is a positive Packages for Fmits. 417 detriment. In very many cases, it is the packing and the package which sells the fruit, more than the fruit itself. When fruits are sold by the defi- nite quantity, as by the quart, the peck or the bushel, the packages should be full measure. It sometimes happens that for a time a man secures as much for a short or snide package as for one of full measure ; but such a person can scarcely expect to hold a superior trade for a great length of time. The most popular package at the present time for grapes, peaches and apricots is the Climax basket, which is made in various styles and sizes. Some of the common forms are shown in Fig. 95. These are made in sizes holding from five to ten or twelve pounds of fruit. They are handy, cheap, nest well in the shipment, and are durable. A good basket of any kind should be one which is neatly made, with no splinters or tag ends hanging from it, which is firm and symmetrical in shape, well nailed, and which is perfectly clean or white in appearance. Baskets become yellow and discol- ored if they are left in the sun; therefore, when they are stored, they should be placed in a clean and dark dry loft or room. If packages which have been left over from the last year are some- what dingy, it is sometimes possible to bleach them by burning a little sulfur in tne room. The grower, then, will begin some months in advance to look up the packages which he shall use, for he will thereby not only suit himself and BB Fig. U4. Various types of fruit packages. »5. Various types of baskets. 420 The Principles of Fruit-growing. the market, but lie will likely be able to secure his packages at a lower cost if he gets them early in the season ; and he will, in any event, be sure of his packages in case there should be a large demand for them at marketing time. It is well to secure the illustrated price- lists of the manu- facturers, and to thoroughly canvas the subjects of styles and prices some months in advance. All packages smaller than a half peck should be shipped in crates. It is customary to use crates with slat sides and an abundance of openings, in order to insure complete ventilation; but if the fruits are firm and dry when they are picked, and are then reduced to a lower temperature, they can be shipped in unventilated crates, generally with better results (page 397). The shriveling and shrinkage of the fruits will be less in the tight crates, and decay will ordinarily be less also. These crates should be gift packages, and made out of light split stuff, as bas- NOTE.— The pictures in Figs. 94-97, pages 418, 419, 422, 42,'i, are shown for the purpose of acquainting the reader with some of the leading types of fruit packages now in use.

Crates which are designed to be returned to the grower are usually heavy, are commonly made of sawed stuff, aud are provided with hinges and clasps. In shipping long distances by rail, large crates (holding as many as sixty baskets or cups) are generally preferable, because there is less "side shake," because of the greater bulk; and such heavy packages are not so carelessly handled as the small ones are. The time is rapidly coming when all the better grades and better qualities of fruits will be put up in special gift packages, and the time can- not be far distant when pasteboard boxes will be used to some extent. One of the most marked re- sults of the recent advancement and competition in the manufacture of products is the packing of single articles in tasty boxes. Boots and shoes, for ex- ample, were shipped loose in large cases a few years ago, whilst now, in all of the better grades, every pair is boxed by itself. In other words, not only is the product itself a finished article, but it is packed in a dainty and finished way, and the same The bushel box; 8. patent fruit barrel; 9.

With these packages the reader should compare Fij. 98, showing crates actually sent into the New York market with pears. The grower was evi- dently of an economical turn of mind, for he had made the packages of the odds and ends of the place,— old boards and old rail, a wagon-jack, and a wagon-reach ! The New York party who sent us these packages wrote as follows : " I found a new fruit package on the market here, and as I know that you are deeply interested in horticulture, this will be of interest to you. Tt was invented and manufactured by a man up the Hudson River, and was used for shipping pears.

He did so, sorting out n few of the smallest fruits, and then sold th« ken for $1." Fig. ye. Baskets ami crates.

In the fanciest fruits, like the best dessert pears, and even some of the largest and finest strawberries, it is often profitable to .ship in cases something like Fig. 98. Novel packages found New York niarkt those used for eggs, in which each individual fruit has a compartment or receptacle of its own. If, in addition, the fruit is carefully wrapped in these com- partments, the very finest type of packing will result. To one who has not followed the market closely, all these suggestions will seem to be expensive and un- profitable ; and this is certainly true of everything Packing Equipments. 425 but the best quality of fruits. The common run of goods will not bear the expense of extra care in the handling and marketing, and this is the kind of fruit which it does not pay to grow. If one makes a study of the market he will soon come to feel that the package and the packing cut a most impor- tant figure in the sales. The package really adver- tises the fruit more than the fruit advertises itself; and it is a well-known business principle that an article which is first-class will stand very heavy advertising, but no other will. PACKING -HOUSES AND APPLIANCES. The subject of packing -houses is one which can- not be treated specifically for each grower, from the fact that every person has a different ideal, and he may grow fruits for a market which demands par- ticular treatment of the products. Amongst the best types of packing-houses, which one generally meets in the east, are those used by the grape men ; and if one studies the question, he will find that there are two distinct types of packing- houses in use in the grape regions. One type is a com- bined packing and storage house, and is used very largely where Catawbas are grown, and where the grapes are often stored for some time before they are marketed. The other type of house is that which is used in the Concord regions, and which is simply a half-way station between the field and the railway station, — a shelter place for the pack- 426 The Principles of Fruit-growing. ing of the grapes, — and is not used for the storage of the fruit. One of the best of the storage type of packing- houses (used for holding the fruit until winter or later) may be described as follows:* It is built on a side hill, and the basement or cellar is used for the storage of grapes, the first floor is used for packing, and the second floor or attic for the storage of baskets, crates, and the like. This build- ing measures 25x60 feet over all. The foundation walls are 24 inches thick, and the cellar is pro- vided with ample means of ventilation by outside windows, and also by means of a chimney which runs from near the middle of the cellar up through the roof. The floor is of dirt. By means of care- ful attention to ventilation, this cellar can be kept to 50° or below during September and October, and is frost -proof during the winter. The windows are provided with close-fitting screens, to keep out rats and squirrels. This cellar will hold easily fifty tons of grapes in the picking trays. The first floor is divided into two rooms, the front one being a pack- ing-room 25 feet square, and the back room being a storage and shipping department 25x35 feet. This packing -room is provided with heat, and is lighted by seven large windows. The floor above the cellar is double and made of 1%-inch matched pine, with an abundant air space between the two layers. This, therefore, protects the cellar from *Bull. 117, Cornell Exp. Sta. Packing -houses. 427 sudden fluctuations of temperature. The building is also shaded, especially from the afternoon sun, by large trees. This building can be erected for about $1,200. It has 18 -foot posts, a tin roof, the two Fig. 99. A good type of packing-house. rooms in the first floor ceiled with pine, but the top floor not ceiled. The other type of packing -house (used only for purposes of packing and of storing packages) is ad- mirably illustrated by Figs. 99 and 100, which are pictures of the house of W. W. Pettit, Brocton, New York. In this case there is no cellar, for the grapes are not to remain in the house more than a day or two at the longest, and they ordinarily 428 The Principles of Fruit-growing. pass directly through it on their way to the rail- way station. This is a house which can be built for about $500. The main floor of the building is 24 x 40 feet, and aside from this there is a drive- way, W, under the same roof, and which measures Fig. 100. Plan of the 40 ft. packing-house. 11x30 feet. This driveway connects with the main floor by two doors. The front room, N, which is lighted by four windows in the front and one upon the side, and is 12x24 feet in size, is the packing- room. In the rear of this is a store-room, E, for the grapes. The half -story above is used for baskets Packing Appliances. 429 and crates, and these are delivered into the pack- ing-room by a shute. This building will accommo- Fig. 101. The packing and sorting of grapes. date ten packers, and will easily handle the grapes from fifty acres of land. In the packing of grapes, the greatest care is required to keep the fruit clean and fresh, to pre- vent the bunches from being broken, and to pre- serve the bloom upon the fruit. It is essential 430 The Principles of Fruit -(/row ing. that the house should be kept thoroughly clean ami sweet at all times. It is especially important that the storage room for the baskets and crates should be dry and airy, in order that the baskets may Fig. 102.

In this case, the picking trays are set before the packers upon an inclined table, and the Packing - houses. 431 packer handles the grapes from this tray into a basket which she places at her left. When the basket is filled, it is placed upon a flat ledge in front of her (R), and is taken off by an attendant, who places the baskets on a truck and rolls them into the back room, from which they are delivered to the wagon. Empty baskets are stored upon the nigh shelf C, and these are replenished by an atten- i'ig. 10.'t. Packinghouse of the Hale orchards, Georgia. dant, as necessary. When the tray is empty, it is slid through an opening just in front of the packer and underneath the flat ledge upon which she places her finished baskets. Fig. 102 shows a packing-table in the packing-room of George C. Snow, Penn Yan, New York. This is a circular revolving table, about 432 The Principles of Fruit-growing. which the packers sit. The packer holds the bas- ket in her lap and takes the grapes off the table, which is turned as fresh fruit is put upon it. This device allows the packer to select from a large quan- tity of fruit. The packing-house of the great Hale orchards in Georgia is shown in Fig. 103, and an interior view Fig. 104. Packing peaches in Georgia. in Fig. 104. The latter picture is a peach -packing scene. The suggestions in the last few pages cover most of the points which it is necessary to consider in the construction of a packing -house. The grower will be able to apply them to his own conditions. A simple temporary shed erected in the orchard is often made to serve all the purposes of a packing- house. A cloth tent is often used. The appliances Sorting -tables and Presses. 433 which are needed in packing-houses, aside from packages and crates, are trucks, sorting- tables, barrel presses, and an abun- dance of baskets or barrels for the refuse fruit. Sorting -tables are of various patterns, but those which are used for apples, cran- berries (Fig. 105), Fig. 105. Sorting cranberries. and other firm fruits, consist of a table or tray about twice as long as broad, narrowed at one end, at which it is open to allow the good fruit to roll off into a basket or barrel. The fruits are poured from the picking baskets on to the table, and a num- ber of persons standing on either side remove the litter and the inferior fruit, whilst they work the good fruit on to the outlet. Of barrel presses there are several styles. The most expeditious is some kind of lever press (like No. 3 in Fig. 106), but more pressure can be ob- tained* with a screw press (7), and such an im- plement holds itself in place whilst the head is being adjusted.

In fact, the same structure may be used for both purposes, as the grape house is which has been described in 'he preceding pages. There is more and more necessity that the fruit-grower should provide the means of storing fruits, when prices are low and competition is very sharp. General advice. — As a rule, it 'will not pay the fruit-grower to build iced storage or chemical store- houses for his fruit, unless he has a very large acreage. This cold-storage of fruit is really a busi- ness by itself, and ivqniivs a great deal of care and skill to carry it through successfully, and a discussion of it is foreign to the purpose of this book. If the grower desires to keep his produce until late winter or spring, and has no cellars or naiural storage place, it will ordinarily pay him Ix-st to put it into some commercial cold-storage house, and to pay so much per package for the storing of it. For temporary storage, however, these remarks will not apply. Every person who grows fruits, especially perishable kinds, should have some kind of a building in which he may place the fruits over night, or for two or three days, when waiting for the market to improve, or for the purpose of cool- ing them down before shipment. These houses are ordinarily cooled merely by cold air. They are often 436 The Principles of Fruit-growing. known as "chill rooms." A room which is well fitted for the keeping of butter in warm weather may also be used to advantage for fruit. In some cases, arrangements can be made for the use of ice to reduce the temperature for the time being. If one has a considerable quantity of fruit, and has a large cellar which is well adapted to the keeping of apples, he can often store his crop to advantage when the price is low in the fall ; but the grower must bear in mind that the risks in the storing of fruit are very great. In the first place, markets may not improve as he thinks they ought ; and, again, the fruit may not keep well. Even when the fruit does keep well, there is frequently a large shrinkage, and the expense of re -packing and han- dling is a large item. The fruit which is designed to be kept for the late winter or spring trade should be carefully sorted when it is put in storage, and especial care should be taken that none of the fruit is over -ripe. (See page 379.) Fruit which is in proper condition for storing when it is picked may be ruined for long -keeping quality by allowing it to' lie in the sun or in a warm place for a day or two. Neighborhood or cooperative storage is often practicable, without, however, attempting to establish a true cold-storage business. C. H. Perkins* has presented the advantages of such an enterprise to the fruit-growers of New York, as a means of sav- *«Cold Storage for Neighborhoods," Proc. 39th Meeting W. N. Y. Hort. Soo., 41 (1894). Neighborhood Storage. 437 ing the fruit crop over gluts, and especially of hold- ing the market from western competition. This would no doubt prove to he a very useful method for the north for the late fall and winter fruit, but it would probably not be practicable for the south, or for holding the summer fruits. "If, there- fore," he writes, "every neighborhood in western New York had a cold-storage house for barreled apples, that would protect against frost and hold anywhere from ten thousand to twenty thousand barrels, run, if need be, on the same cooperative principles and methods as the cheese factories of this state, or the fruit associations of California or Michigan, would not the result be very much more satisfactory to the grower than present methods? * * * * * Such a building may be of moderate cost and yet substantial and durable, and need not always be located at the nearest railroad. How many have ever figured or thought of the cost to the grower of transporting his apples to the railroad or canal station from his farm during the months of Sep- tember or October, when there is much work to do and time is of most value ? Say that the grower is five or eight miles from said station. I believe that for less cost per barrel the dealer located in western New York will deliver the same apples in barrels at Chicago, Milwaukee, Duluth, Philadelphia, New York, or Boston. There are quite a number of apple houses in western New York owned by dealers, but there are few that were built for the express pur- pose of safely storing apples. I have a building that 438 The Principles of Fruit -growing. was built for the storage of nursery stock, and in which I have had apples stored all winter. It is frost- proof, built on a heavy stone wall twenty -four inches thick and three feet high. On this wall were set up two by four scantling ; these were sheathed with inch hemlock, then covered with tarred building paper, then furred out with strips four inches deep, and again covered as before, until the wall has three air spaces. The roof is constructed in the same way to protect against frost. Light and ventilation come from two rows of windows at the top. The roof is gravel. The outside is covered with novelty siding. The building has double or two sets of doors at each end, and a driveway through the center. It is painted inside and out, is one hundred feet long by forty feet wide, the whole cost was $1,400, and it would afford storage for ten thousand barrels. The atmosphere is the same inside as out, only that the building is frost -proof and can be run in the winter months with a variation of not over 12°; there is no smell of a cellar whatever, and stock always keeps perfectly. Such a house, or a better one, in a neigh- borhood, would pay four years out of five, at least 50 cents per barrel over all cost of labor for han- dling, sorting, insurance, etc., and this year where there were apples, it would have paid $1 to $1.50 per barrel." Requisites for domestic storage. — The home storage establishment is generally either a cellar or a half- cellar, although, by taking particular pains in the construction of air spaces, a building entirely above Features of a Storage House. 439 ground may be made to answer the purpose. A building wholly on the surface, however, is more likely to give variable temperatures than one which is partially under ground. An ordinary house cellar, if it has good ventilation and is not too dry or too warm, may answer very well for the storage of fruit; but it is ordinarily best, both for purposes of storage and for health, that the fruit cellar should be a sepa- rate structure if products are to be stored in any quantity. The requisites of a good storage cellar for fruit are chiefly four : protection from frost ; the ability to secure a uniform or unvarying- temperature of 40° or below ; facilities for ventilation ; and air which is moist enough to prevent evaporation. The protection from frost is secured either by sinking the building below the surface of the soil, or by making two to four air spaces in the walls in that portion which stands above the earth. The ven- tilation should include facilities for removing the warm and impure air from somewhere near the top of the structure. Some kind of a shaft or chimney construc- tion, with a valve or shutter which can be opened or closed as necessary, will answer this purpose. In buildings which are above ground, it will be often necessary to provide some means of taking in the cold air near the bottom of the building, especially before the cold weather of winter sets in and after the warm weather of spring begins. Cold air being heavier than warm air, it settles upon the surface of the ground in still nights, and if the floor of the storage structure is two or three feet below the top 440 The Principles of Fruit-growing. of the ground, this cold air may be drained into the building by means of flues which are. laid through the walls, the outer ends standing just above the earth. Six -inch sewer pipes, at intervals about the building, answer this purpose admirably. In a build- ing thirty feet wide and seventy feet long, three of these valves along either side, and one upon either end, are probably sufficient for all ordinary require- ments. Sub -ventilation is sometimes recommended, and may often work to good advantage. This is secured by running a long pipe from near the bottom of a cellar storage out to the surface of the ground six or more rods away. This pipe has a valve at the outer end, or at least some protecting structure to prevent the leaves and litter from blowing into it, and it is ordinarily best, also, to have a valve at the inner end. Inasmuch as the earth about this subterranean passage is not frozen during the win- ter, cold air may be drawn in from the outside and be warmed up above the freezing point in its passage through the tube. This type of ventilation has been used with success in cellars designed for the wintering of bees. It should always be remem- bered that cold air contains less moisture than warm air does. When very cold air is admitted, therefore, moisture is rapidly taken up when its temperature rises, and the cellar may be made too dry. It is advisable, therefore, to raise the temperature of such air to nearly its ultimate or required degree before it enters the storage room. Cellars which are very dry cause the fruit to Keeping Fruit on Trays. 441 shrivel. Those rooms in which there is a natural sand or gravel bottom ordinarily keep fruit in the best condition. Cement bottoms are very apt to be too dry. Running water is very often desirable in a fruit cellar, not only because it furnishes moisture to the air, but also because it is an equalizer of the temperature. One must be cautioned, however, that a cellar which is not properly ventilated will cause the fruit to mold and decay, if it is wet. In gen- eral, it is best to have means for supplying fresh air, and then keep the cellar simply moist, not wet. One should avoid drafts in the storage cellar, for currents of air are very likely to cause the fruit to lose moisture and to shrivel. Much is said about the keeping of fruit upon trays in cellars rather than in barrels or crates, but this must be determined by the character of the cellar as to temperature and moisture. In cellars which are too dry, the fruit should be left in the closed packages; but if the air is moist and the tem- perature very low, the fruit may be placed upon racks or trays to the very best advantage. But in any case, it should always be remembered that fruit which has been placed in storage for a month or more, should be re-sorted and re -packed before it is put upon the market. It has been said (page 436) that the best results in the storing of fruit are had when the product is very thoroughly sorted before it is put into the cellar, for even if the cellar is very nearly perfect for the keeping of the fruit, any over-ripe or decayed specimens will very likely break 442 The Principles of Fruit-growing. down, and spread the contamination to the entire sample. The fruit should be cooled down somewhat before it is placed in cold storage, especially if there is much of it, otherwise it raises the temperature of the compartment. The requisite features in a domestic iced storage house are set forth as follows by Hexamer : * " To preserve fruit or retard its ripening, it has to be stored in pure, dry, cold air. These conditions can be produced in various ways. But the simplest and least expensive method for farm use is to build a two -story ice house, the ground floor of which is for the storage of fruit and the upper for ice. The most important part of such a house is the proper con- struction of the dividing floor upon which the ice rests. The timbers, the size of which depends on the quantity of ice to be supported by them, are so ar- ranged as to have narrow openings between one another to permit the cold air from the ice cham- ber proper to descend to the storage room below, and also to facilitate the dripping of the water from the melting ice. r'To prevent the water from falling on the fruit, an additional floor or roof has to be constructed under the dividing floor. The best material for this purpose is galvanized, corrugated sheet iron, arranged so that all the water which falls upon it flows into a gutter connected with a leader, through which it is carried into the main drain. Dryness in the storage *Dr. F. M. Hexamer, "Cold Storage Fruit House," Auier. Agric., Jan. 3D. 1897, 135. Storage for Or apes. 448 room being of prime importance, the floor should be cemented whenever existing conditions permit. Of course, ample provision has to be made for thorough drainage, ventilation and circulation of air. Several devices for the accomplishment of this have been patented, and an excellent non- patented plan is minutely described and illustrated in Theron L. Miles' hook on the 'Ice Crop.' The general construction of the walls, roof, ventilation, etc., of such a storage house does not differ materially from that of ordinary ice houses. If the storage house is used much during hot weather, the greater part of the ice will probably have melted before the fall fruit comes in. It will therefore be necessary to have a reserve ice house near by, from which the storage house can be re- plenished." The requisites for keeping grapes during the winter are given as follows by George C. Snow:* "Any good building in which the temperature can be held even at about 35°, with ventilation as may be required, this to be determined by noting how the fruit is keeping, will be found available for grapes. No positive rules can be laid down. A cooling room, in which the fruit can be first cooled, is a necessity. If placed directly in cold storage, the temperature will be found to be raised rapidly by placing a quantity of warm fruit in the room. As even a temperature as possible is much the best. Grapes should not be packed in baskets for shipping before being stored. They should be ripe, as grapes do not mature after *Rural New-Yorker, K.-l,. J, lx'M\ • Mull. 117, Cornell Kxp. SU. 444 The Principles of Fruit-growing. picking. Niagara or any other variety can be held only for a limited time, some varieties longer than others." The following temperatures at which a cold stor- age company (Geuesee Fruit Company, Rochester, New York) engages to hold certain products, will be in- teresting to the horticulturist: GOODS. Temp.

NOTE.— The director of the Genesee Fruit Company writes under date of May 22, 1897, as follows : "We carry apples at a temperature of 30 degrees, and we would advocate carrying them at 29 degrees for the first month in storage. Apples are going out of our warehouse in perfect condition ; in fact, there was one small lot, consisting of 198 barrels of Baldwins, which went out two weeks ago, and they were all run (or sorted), and the shrinkage occasioned by decay was 1% barrels. One of the roost essential features in carrying apples is getting them in storage directly after they are picked from the trees, and we do not advocate receiving Greenings for storage after October 20." Fruit -houses. 445 Fig. 107 shows a simple fruit -house, with tiers of trays upon either side of a central passage-way. The chimney and the area in the floor allow of change of air. Fig. 108 is a fruit -house of the late Charles Downing, of pomological fame. Whatever the style of the fruit -house, the walls above the surface of the ground should be well provided with air- spaces. The accompany- ing details of the con- struction of celery houses Fig 107 Simple fruit.house. (Figs. 109, 110), will suf- ficiently explain some of the problems which should be considered.* "This structure has a brick foundation, and the roof is well provided with air chambers and paper linings, affording the best protection against cold. The additional large air chamber above the collar beams, with its separate windows, seems also desirable. There are large double doors at each end, and the space between each outer and inner door is large, and the connections are well arranged for the exclusion of cold air. It seems of sufficient interest to give a view of such a storage house ; but full details of construction may not be entered upon in this connection. It will be seen that Fig. 109 shows the construction of the peak and collar-beam (k) of the house, and also of the ventilator (1. 1). Fig. 110 *B. M. Duggar, Bull. 132, Cornell Exp.

The owner of this house (T. L. Kinney) gives the following information (See Fig. 112): "The fruit house is built on high and dry ground.

Apple house; from the islands of Lake Chainpliiin. and plaster ; inside of studding, matched pine, then paper, and then one -half -inch sheathing, painted. This gives two hollow walls, or dead -air spaces. For ventilating, there is one ventilator from cellar to the observatory on top of building, which has four large- window frames, with blinds, but no tight windows. The ventilator opens into both storage rooms. We DD 450 The Principles of Fruit-growing. have three eighteen -inch windows on east and west sides of building in the cellar, and three large win- dows in west side, next to store room. Both floors are double, with paper between, and the second room is ceiled overhead with matched spruce, and painted. The two windows on east side show in cut, with the outside doors. "About picking time, we begin to cool off the building by keeping open during westerly winds or cold waves, and closed as much as possible when it is warm. We try not to put in any fruit when the fruit is warm, but have it cool, if possible. In this way the air in the building is cool all the time. I have kept a partial daily record of the temperature in the cellar this winter (1896-7) since December 28, the results of which are as follows: CELLAR. SECOND BOOM. DATE. Temp. DATE. Temp.

This difference is occasioned by the cellar being nearly full of barrels of apples, y ./&\ Fig. 112.

I have no fire except an oil stove, and have not used that yet. I think that winter apples will keep as well at a temperature of 36 as 32°; yet, I have no proof of it. I do not like to have the apples get too cold, as we have twelve miles to haul to the car; and if the fruit is kept too cold, it is more likely to freeze on its long trip to market." A "new plan for the construction of a storage cel- lar" is given by Alwood:* "The winter storage of fruits and vegetables is a question of much importance in this state [Virginia] because of the wide range of temperature which prevails during that sea- son. Also, temporary summer storage is a subject worthy of careful attention, and may be to some extent solved by careful application of the principle explained in this article. The com- mon practice for winter storage largely in vogue over this state, is to bury such vegetables and fruits as are required for winter and spring use in outdoor pits. The particular method followed varies with the different kinds of crop to be preserved, but the essential facts are the same. This system of pitting can hardly be considered a success so far as relates to the main crops stored; viz., apples and potatoes. The essentials of win- ter storage for apples and potatoes are a low, dry, even tem- perature, and to secure this without artificial cold storage is a problem that cannot be met by the outdoor pit methods of burying these staple articles. These two crops are necessarily held by growers in considerable quantity for winter and spring use, and the problem of storing them in a convenient and suc- cessful manner is the one had in view in the discussion which follows. It may be well to state at the outset that we doubt the even partial success of the plan herein explained for all of *W. B. Alwood, Bull. 11, vol. iv., Va. Exp. Sta. Virginia Storage House. 453 that portion of the state lying east of Piedmont. Several years since, we concluded to construct a simple storage cellar upon a plan which we once heard discussed, but had not seen carried into practice. In fact, our building is the first one constructed on this plan of which we have any knowledge. ''The essential features involved in the storage building which we designed for this purpose are : First, a cellar exca- vated into a gently sloping hillside, carried into the bank far enough to place the cellar room entirely below the surface of tho earth, and yet give opportunity to enter the cellar easily by an inclined way from the lower side of the slope ; secondly, a flue leading out from near the center of the floor of the cellar room, along the bank of the hillside for a considerable distance, with sufficient fall to make it act both as a drain pipe and a fresh air flue ; thirdly, ventilating flues placed at each end of the cellar room or elsewhere, as desired, and rising to the height necessary to give a sufficient draft to carry off rapidly the air from the cellar room whenever ventilation is desired. "The cellar room will better serve the purpose of cold stor- age if the excavation is carried back into the bank so as to make the floor twelve or fifteen feet below the lowest point of the adjacent hillside. In the case of the cellar built here, the excavation is only ten feet deep at the deepest point, but we are now satisfied that a greater depth would give better results. The principle of a subterranean air flue is the essential feature of this cellar. In its use we aim to secure a dry, even temper- ature in the cellar by admitting air as desired through this flue. It should be at least six inches in diameter and, we now think, should be laid, at a depth of eight or nine feet, along the bank of the hillside, for a distance of about five hundred feet. It is not necessary that this flue should lie in a straight line, but any departure from a straight line should be a gradual curve, so as to permit an unobstructed flow of air into the cellar. Situated at this depth, and having a length approxi- mately as stated above, the air flowing into the cellar through this flue will be in summer reduced, and in winter raised, to the temperature of the soil at the depth stated, which will 454 The Principles of Fruit-growing. approximate somewhere between 50° and 55° Fahr. during the entire year. The above statement is based upon the observed temperature of perennial springs in this vicinity. "From the foregoing it follows that if the air in the cellar becomes warmer than the air in the underground flue, it will rise through the ventilating flues, and the colder air will flow in from the supply fl'ie, as desired. The temperature of the cellar room can thus be approximately controlled to at least the neighborhood of 55° to 60° Fahr. The construction of the cellar is shown somewhat in detail in the drawings below. These figures are not intended as working drawings, but serve to bring out the essential ideas and plan of the structure suffi- ciently to enable any mechanic to carry them out on larger or smaller scale to suit the needs of the builder. Fig. 113 is a Fig. 113. Longitudinal section of Alwood's house. longitudinal section through the cellar room, and shows also a side elevation of the storeroom above. The two ventilators a a rise through the storeroom, and are six inches in diameter by fifteen feet long, thus insuring good draft. The air flue 6 Virginia Storage House. 455 enters under the foundation and discharges fresh air into the cellar room near the center. This flue is six inches in diam- eter, and theoretically should be extended far enough along the hillside to admit of tempering the air to the temperature of the ,* gggg} . 1 •« i | i * £ - ". :. % •• *...:•....„ ; V *?

The cellar built here has an air flue only one hundred and fifty feet long, and we have never been able to cool the air down below 60° Fahr. when the temperature of the outside air is above 70° Fahr. "The dotted line h h shows the contour of the hillside, and the line i shows the entry-way into the cellar. The entry-way should preferably be on the north side of the structure, and should be closed in by a vestibule, so as to protect the cellar- way from storm, and to prevent influence of outside temperature upon the atmosphere in the cellar. "The roof structure of vestibule is shown at d, and one of the side walls of the entry-way at e. The floor of the cellar // pitches slightly to the mouth of the air flue b, which serves as a drain pipe when one is needed. The cellar floor is made of broken stone and cement, and successfully checks the upward rise of ground water. The bins c c and c' on one side of the cellar room are shown, with dimensions. They are constructed of two by four scantling and one inch oak boards. At c the facing on lower bin is shown in position. When we desire to fill the bins additional facing boards are used. The letters A; k 456 The Principles of Fruit -growing. at lower ends of ventilating flues indicate position of sliding dampers, by means of which the flow of air from the cellar is effectually controlled. With the short flue used in the cellar here, we find that when the mercury remains below 20° Fahr. for any length of time the cellar will be reduced below freezing, unless the ventilators are closed. "The dimensions of the ground plan of the cellar are shown in Fig. 114. The letters so far as used always indicate the same part of the structure in the several figures. This figure Shows the walls to be constructed of stone, which is unquestion- ably the proper material. In our building, which was con- structed to test the practicability of an idea new to this class of structures, expense was avoided so far as possible, and the walls are built of wood. The framing of the walls is constructed of two by four scantling framed into sills laid in broken stone and cement. The corner posts are four by four scantling. This frame is covered outside by a double sheathing of inch oak plank. The first course was put on diagonal and covered with strong builder's paper, and over this a perpendicular course of sheathing was put on. The whole structure was then literally soaked with crude petroleum, and the earth rammed in tight around the cellar story and banked up, so as to carry surface water away from the walls. Inside the walls were covered with mch oak boards, and -the bins constructed as indicated' in the drawings. The entry-way to the cellar is wide enough to admit of backing a horse -cart or wagon down into the cellar, so as to unload directly from it. This is a matter of much convenience to the workmen. The width of the cellar floor will permit of a row of barrels being placed in front of the bins and yet admit the vehicle. "A series of observations on the range of temperature in the cellar was made during November, December, January and part of February, and the results are summarized below. The ven- tilator and the supply air flue were all left open from November 1 to December 10. The outside air temperature registered 28° on the morning of the first of November, and the cellar showed a temperature of 46° Fahr. As the month progressed, a period Virginia Storage House. 457 of warm weather set in, without a drop to freezing from the 7th until the 24th of the month. During this time the temperature often registered above 60° in the shade, with maximum readings considerably higher. The cellar temperature varied just 12° for the entire month, reaching 58° on two occasions, but closing the month at 46°, with outside temperature at 34°. During Decem- ber the cellar temperature was reduced quite steadily from 45° to .'58°, the daily variations being at most 2°. Outside temperature varied considerably, but the range was between 15° and 46°. Quite a number of observations was made on the working of the supply flue and the ventilators. The tests made showed that air passed through the one hundred and fifty feet supply flue in thirty to forty seconds, and the ventilators could be depended upon at all times to keep up a movement of air in the cellar so as to draw a fresh supply. In fact, during the coldest weather we frequently closed the ventilators to prevent the too rapid lowering of the temperature in the cellar. The tests showed that this short flue could not be depended upon to raise the air to a proper temperature when the mercury outside was at 15° or lower. Our observations showed that the air was, under these circumstances, raised about 20°, varying, of course, with conditions. During January further experiments showed that we could quite easily reduce the cellar temperature to 35° when the outside air regis- tered 15° to 20°. However, the building proves to be lacking in two essentials to hold the cellar temperature stable; viz., it is not deep enough in the earth, and the floor between it and the tool-room above is not properly laid. This floor is made double, of half -inch stuff, while we now see that the cellar-room should also be ceiled in the best possible manner, to prevent interference by outside changes of temperature. The total range in the cellar during January was 35° to 42°. This result was, however, se- cured by carefully watching the conditions, so as to admit cold air during the night or periods of low temperature and then clos- ing the flues when the outside temperature would act injuriously upon the temperature of the cellar. With the temperature fluc- tuations which prevail in this region, much attention is necessary to properly control the conditions in the cellar." 458 The Principles of Fruit-growing. Alcoholic vapor as a fruit -preservative. —In connec- tion with cold storage, it may be possible to experi- ment with the "new process for keeping fruit fresh," which was published in 1895 by the Department of State (Bureau of Statistics, by Henry P. DuBellet, Consul at Rheims, France), and distributed by the Division of Pomology of the Department of Agricul- ture : "The great difficulty experienced in preserving fruits in their natural state is such that the dealers who make the attempt of furnishing them out of season are compelled, on account of the heavy losses they sustain, to sell their goods at prices which ren- der it impossible for the great majority of families to place fresh fruits on their tables during the winter months. The high prices which fresh fruits command on the city markets increase day by day from the time they are gathered, and have induced orchard and vine owners to run many risks in order to keep their fruits as long as possible before offering them for sale. And it is not surprising that no pains, efforts, and sacrifices are spared to reach the coveted result, when it is known that during these last years, first-class grapes sold from 2 to 4 francs (38.6 to 77.2 cents) per kilogram (2.2 pounds) from September to November, that they were worth 8 francs ($1.53.4) and as much as 12 francs ($2.31.6) in February and March, and 14 francs ($2.70) in April and May. "These exorbitant prices show plainly how imperfect are yet the means employed for keeping fruits fresh, how few must be the successful efforts, and how many the difficulties encountered. The solution of this question is, therefore, of great interest to all, and the result of the experiments made in the latter part of the year 1894 and lately reported to the Horticultural Society of Soissons by Mr. A. Petit, chief of the laboratory of horticultural researches at the National Horticultural School of Versailles, de- serves the attention and consideration of fruit-growers through- out the United States. Alcoholic Vapor to Preserve Fruit. 459 "Impressed with the powerful action of alcoholic vapors on the mold which generally appears on the surface of fruits in a damp atmosphere, Mr. Petit noticed that pears and apples kept for sev- eral months in a surrounding saturated with vapors of water and alcohol, even were they at the beginning in a state of decay, showed no signs of mold, while fruits in every particular identi- cally similar to the former, stored under the same conditions, but not exposed to the action of alcoholic vapors, were entirely cov- ered with it. "Taking advantage of this observation, Mr. Petit applied the principle to the preservation of fruits in general, and most par- ticularly to grapes, because, more than others, the latter are sub- ject to mold. It was to be foreseen that grapes kept, from the day they are cut off the vines, in an atmosphere saturated with vapors of water and alcohol would, by the retarding of the sweat- ing period, not only remain free from mold, but would even re- tain their natural aspect. Consequently, should the temperature be constant and low, the preservation could be maintained long and well. "On the 31st of October, 1894— that is, very late in the season and at a very unfavorable time — Mr. Petit placed, with other fruits and a bottle filled with 100 cubic centimeters (61 cubic inches) of alcohol at 96°, some bunches of grapes known as 'Chasselas de Fontainebleau,' fresh from the vine, in a brick recipient in the form of a parallelepiped, cemented inside and closed as hermetically as possible by a common wooden door. In two similar recipients contiguous to the first, one of which was kept open "and the other closed, but without alcohol, were stored similar fruits from the same trees and vines. The fruits were laid on wood shavings. The recipients were built in a very damp cellar, the temperature of which varied regularly from 10° to 8° C. (50° to 46§° F.) during the whole time the experiment lasted. "On November 20, the grapes placed in the recipent left open, and especially so those in the closed recipient without alcohol, were mostly rotten and covered with mold, and were immediately removed. In the recipient containing the bottle of alcohol, the 460 The Principles of Fruit-growing. srapes were beautiful ; on one bunch, two grapes had turned brown, but were firm, full, and free of mold; they did not taste at all sour, thus differing essentially from moldy grapes, espe- cially those subject to Penicillium glaucum. The hair hygrometer in the recipient registered 98°. On December 7, the bunches of grapes in the recipient containing the alcohol had kept their fine aspect; on most of them, however, one or two grapes had turned brown, and were in the same condition as those above referred to. On December 24, same results ; on most of the bunches could be seen one or two grapes commencing to decay. At the end of nearly two months, each bunch had lost but from two to four grapes each and all were in a perfect state of preservation, the stalks being perfectly green and the grapes firm, full, and savory, and having all the qualities of fresh -cut grapes. "At the conclusion of the experiment, 28 cubic centimeters (17 cubic inches) of alcohol at 60° remained in the bottle out of the 100 cubic centimeters (61 cubic inches) at 96°, but, as Mr. Petit remarks, the door of his recipient had not been built with great care and did not close hermetically, hence a useless con- sumption of alcohol. "This process offers many advantages. It is simple, easy of application, and cheap, and, if adopted by our fruit-growers, would allow them not only to hold their fine fruits until they can dispose of them at a fair price, but would also insure them hand- some profits during the winter months." Beckwith makes the following note* upon this method: "For the purpose of testing the process as described in the above circular, two fully ripened branches of Norfolk grapes were placed, together with two ounce bottles filled with alcohol, upon a large pane of glass and covered with a glass bell jar. The grapes thus prepared were placed upon a table in my laboratory, where they remained until December 18, perfectly sound and plump in appear- * Eighth Ann. Rep. Del. Exp. Sta., 110. The Grower and the Consumer. 461 ance, but had changed to a slightly darker brown color. The flesh was sound and firm, and still re- tained nearly its normal flavor. The grapes re- mainded under the treatment until February 10, when they were removed. At this date, nearly all of the grapes were firm and plump, a few having become somewhat shriveled. They had a peculiar alcoholic taste, having entirely lost their normal flavor. The flesh was very firm, and of a light brown color. The above was, of course, a severe test of the process for keeping fruit fresh, and could not be considered a success. It is possible that by placing the fruit in a cool apartment it could be preserved for a considerable length of time without any great expense." SHIPPING, AND REACHING THE CONSUMER. The grower and the consumer. — The means to be employed in reaching the consumer are such per- sonal matters that little specific advice can be given upon the subject ; and the suggestions which are here made are not meant to apply to the buyers of fruit, nor to those growers who sell their fruit to itinerant buyers. It should first be said that the fruit itself is the best business card which the grower can have, in the long run. Fruit which is well grown and well packed is already virtually sold. If the consumer is convinced of the honesty and good faith of the grower and the packer, then his suspicions are allayed, and he is willing to purchase 462 The Principles of Fruit-growing. freely, and at a fair price. If the grower's name is upon the package, it becomes a guaranty of the quality of the fruit, and the consumer buys confi- dently. If, in addition to this, there is some neat and unique label attached to the package, the con- sumer will be convinced that his grower is not only willing to be responsible for the quality of the fruit, but that he is also a man of business in- stincts. It has recently been remarked that the Canadian apples which are shipped into the Ameri- can markets bring a better price than the domestic products, and very largely for the reason that the law demands that the fruit should be marked "Canadian grown," and the grower ordinarily places his name upon the parcel. The buyer in such case knows who is to be held responsible for the prod- uct in case it does not come up to his expecta- tions. The time is certainly coming when an in- ferior grade of fruit cannot be put upon the market with profit. Competition is gradually increasing, and it is only the better grades which can pay for the expense of shipping and packages and selling, and leave a margin of profit to the grower. The gist of the successful distribution and sell- ing of fruit lies in searching out the best markets, and then in finding out what the consumer wants. This can be done only by giving as much atten- tion to the market end of the business as to the distinctly agricultural end of it. The grower who expects to handle his own fruit directly should visit the markets, and should take particular pains Finding a Market. 463 to determine the especial types and brands of fruit which the consumers in that market require. It is generally true that the fruit-grower raises whatever comes handy, and sells it if he can. It would be better business to determine what the market is likely to demand, and then to grow the article that is wanted. The essence of modern trade is the specialization of business and the individualizing of the consumer. The person who has much fruit of good quality to sell should begin to look up his markets some weeks in advance of the market sea- son ; and he will ordinarily do well to sell some- what by sample. Regulation packages, with his ac- customed grade of fruit, may be sent here and there to dealers and consumers, to represent the product which he has for sale. Much of the success of this type of" marketing depends upon the quantity which the grower can provide. Dealers ordinarily demand that the grower furnish them with stated quantities of stated varieties ; and if the grower cannot do this he may be unable to hold his cus- tomer, and must simply meet the vagaries of an incidental trade. The grower or shipper should notify his dealer in advance as to the amount and quality of fruit which will be likely to reach him at any given time. The dealer is then able to inform his customers and to find an outlet for the product. It should be remarked that this matter of finding a market is a perennial enter- prise ; that is, it is one which must be renewed every year, for the market of one year may not 464 The Principles of Fruit -growing. be the best market for the following year. The market details should be followed up with the same thoroughness which the grower gives to the new development in varieties, and in means of contend- ing with fungi and insects. The selection of the middleman, through whom the fruits are to be sold, is one of the most im- portant features in the whole range of fruit market- ing. The first requisite is that this man should be honest and capable. Then the grower should place great confidence in his judgment, for, as he is nearer the point of consumption, his advice should be worth much more than the judgment of one who is far away. Too many growers are guided m their selection of a merchant by high quotations and flattering letters which are sent out at the be- ginning of the fruit season, but it is often true that the man who at the beginning of the season makes the most moderate and conservative quota- tions, is the one who secures the most profit for the grower in the end.* If one is to reach special and personal markets, the small package is nearly always advisable ; but in the wholesale and impersonal methods of market- ing, the large package will no doubt prove to be the most economical, not only because it costs less for a certain quantity of fruit, but because the ex- pense of packing is less. In the early days of commercial fruit shipping in this country, the large *Por a sketch of the rise of the auction system of selling fruits in this nountrj, see Annals of Horticulture for 1892, p. 43. Sizes of Packages. 465 package for peaches and other tender fruits was commonly used. Peaches were shipped almost wholly in bushel baskets. With the increase and speciali- zation of the business, however, smaller packages were in demand, and in some of the largest peach regions of the country, the product was finally shipped in fifth and sixth -bushel baskets. Now that the production has come to be enormous, however, and the returns to the individual grower are com- paratively light, there has again arisen a demand for the large package. All this is well illustrated in the Lake Michigan region, in which the bushel basket has recently come into great use. The prob- ability is that if the low price of grapes continues for a few years, there will arise a great demand for a larger package. The individual grower who has a special market to reach, however, will still find that the small package is as useful as ever, and it may perhaps have an added advantage be- cause of its contrast with the larger ones in com- mon use. There is likely to be, therefore, a differ- entiation in the use of fruit packages, tending upon the one side towards a larger wholesale package, and on the other towards a small retail and per- sonal package. It should be said in passing that one reason why the small package falls into disfavor is because the fruit is so completely packed by hand that there is a great temptation on the part of the grower to include fruits of poor quality, or at least not to keep up the standard of an arbitrary grade. When 466 The Principles of Fruit-growing. large packages are used, and the grades are not so carefully made, there is less reason for finding fault with a few poor fruits. It is also true that many of the packages, especially in the handling of peaches, have been too small to allow of thoroughly honest packing. This is true of the fifth and sixth -bushel baskets especially. They are either too high or too low to allow a given number of full tiers of fruit to be placed in them, and in order to bring the top layer up to its required height, it is often necessary to insert a layer of small fruits somewhere below the top ; and this small fruit is commonly placed in the middle, because the packer cannot always dis- cover if he must use it until the package is par- tially filled. In the distribution of fruit, it should be re- membered that the establishing of a reputation for the fruit is quite as important as the securing of a remunerative price for the present samples; there- fore, the inferior fruits and culls should be kept in the home markets, or manufactured into cider or other secondary products ; or, if shipped, they should be placed upon the market without guaranty and without the grower's name. They are then sold simply upon their merits, without the recommenda- tion of the grower's name or any attractive label or description. Refrigerator cars. — Fruit which is of superior quality will pay for considerable extra effort in transportation. If it is of a perishable nature, and the market is more than six or eight hours away, Refrigerator Cars. 467 it may pay to ship in iced cars, particularly if the weather is very warm. In shipping fruit in iced cars, it is important to know that the car should be iced some time in advance of its receiving the fruit. This is for the purpose of completely cool- ing off the car. The ice should be put in at least six hours in advance of the loading, if possible, and a longer time is very often advisable. The trans- portation companies should be notified in advance of the number and route of the cars which are ship- ping, in order that the ice may be renewed at the necessary intervals. It may be said, also, that the car should not be completely filled with fruit. The upper part of the car is apt to be very hot, especially in summer, and if space is left above the fruit there is better opportunity for ventilation. About three hundred bushels of fruit in bushel packages should be the limit of the amount in any one car. Earle writes* as follows upon shipping in re- frigerated cars : "Many difficulties and much prejudice were formerly en- countered in shipping fruits under refrigoration. Dealers and buyers were afraid to handle fruits that had been on ice, claiming that they would melt down and spoil as soon as they were removed to the warmer air. This belief was wide- spread ar 1 deeply seated, and it has taken much time and many practical demonstrations to fully convince the trade of its falsity. It probably originated in attempts to save fruit that was already over-ripe, and on the verge of spoiJing, by placing it in the ice-box. Such fruit will be preserved for *F. S Earle, Bull. 79, Ala. Exp. Sta. 468 The Principles of Fruit -growing. some time, if kept cold enough, for cold arrests the growth of the organisms of decay. The decay is only arrested, how- ever, for these organisms are not killed by the cold, and as soon as such fruit is again brought into a warm atmosphere they rapidly complete its destruction. If, however, the fruit is taken from the field at the proper stage of maturity, and is placed at once in a refrigerator car, the cold prevents the beginning of incipient decay; and the fruit will arrive at its destination in a condition to keep almost as long after taking it from the car as it would have kept in the open air at the time it was picked. Strawberries must be in the best possible condition, and the weather not too hot, for them to stand thirty-six hours' transportation by express; or, in other words, for them to reach market in good condition on the second morning after picking. In the writer's experience, strawberries have been repeatedly sent from southern Illinois to Detroit, a three-days' run, by refrigerator freight, and have been successfully reshipped by express to Canadian points that were not reached till the second morning after leaving Detroit. "Again, no fruit is more perishable than a fully ripened peach; but peaches fully mellow, and ready to eat, have been put in refrigerator cars in California, and, after a six-days' run to Chicago, have been reshipped by express to New York, reaching there in condition to bring good prices. Of course, to endure such severe tests, it is necessary to have the fruit very carefully assorted and packed. A very few specked peaches or rotting strawberries would spoil au entire package before reaching so distant a market. Good judgment, too, is necessary in picking fruit at the proper stage of maturity for refrigerator shipment. Of course, it should not be too ripe, but the mistake is much more often made of picking it too green. In shipping by freight in open cars, it is often nec- essary to pick rather green, but with most fruits this is done at great sacrifice of quality. Under refrigeration, fully ma- tured ripe fruit will keep better than that which is grass green. This is an important point in favor of refrigeration, and one that many growers do not understand, for it enables Earle on Refrigerator Cars. 469 fruit to be put on the market after its full flavor and qual- ity has been developed. The flat, insipid quality, and lack of flavor so often noticed in California fruits on the eastern markets, comes very largely from the pernicious habit of green picking. A peach that is ripe enough to be fully mellow is hard to handle without bruising, but they should hang on the tree till fully grown and colored. A peach that would be mellow if left on the tree till to-morrow, is in just the right condition to pick to-day. Pears, on the other hand, should be picked green, at least ten days to two weeks before soft- ening, and should be ripened in a close, dark place. For this reason, they can be safely shipped in tight boxes or barrels in open cars, unless it is intended to place them in cold storage on arrival. In this case, they should be shipped under refrigeration, to retard the ripening process as much as possible. "Refrigerator cars were first built for the meat trade. The meat was hung in cold-storage houses, and was loaded into the cars at or near the freezing point. In a tight, well built car such a cold load would warm up very slowly, and a small amount of ice served to carry it safely to its destination. When it was attempted to use these cars for fruit, the hot load, fresh from the fields, soon melted the limited ice supply, and the cars invariably arrived heated and in bad order. To use these cars successfully, it was found necessary to build cooling houses at the shipping points, in which the fruit could be cooled off be- fore loading, as in the case of the meat. This caused delay in getting the fruit on the market, and made much additional ex- l»ense. It, however, demonstrated the success of refrigeration for the transportation of fruits, and soon cars were built espe- cially for the fruit trade, with sufficient ice capacity to cool off a load of hot fruit in transit, and to keep it cool. At the present time there are a number of refrigerator car lines, with specially built fruit cars, that are actively competing for the fruit, and vegetable carrying trade; so that any point, having sufficient business to offer, can secure efficient car service, with competent men to look after the proper loading and icing of the 470 The Principles of Fruit-growing. cars. Each line, of course, claims to have the best cars; and for difficult service there would certainly be considerable choice between them, but with the numerous re-icing stations that are now available, any of them will give satisfactory service, if properly loaded and handled. "The main points to consider in selecting a refrigerator car for transporting produce are first, its ice capacity, and second, its insulation. The ice tanks should hold at least five tons of ice, and six tons is even better. The position of the tanks, whether overhead or at the ends, is a question .of minor im- portance. The car should be tightly built, with double walls and roof, with the space between them filled in with some non- conducting material, or by numerous linings of building paper, with dead air spaces between them. The doors should be built like the walls, and be of the same thickness; and they should fit as nearly air-tight as possible. Of course the car should be sweet and clean. "It is usual for the refrigerator companies to furnish their own men for loading the cars, for proper loading is a point of so much importance that they do not care to trust the repu- tation of their cars to inexperienced men. The important points to secure in loading are first, that the packages be so spaced that the cold air has immediate access to all sides of them, and second, that they be so secured that the load cannot shift by the bumping of the cars while in transit. These points are usually secured by piling the crates or other packages one above another in tiers or ranks, from three to six inches apart, and with lath or strips between each layer. Strips are placed upright against the end of the car, and a row of packages is placed on the floor, with the ends set snugly against these strips, and carefully spaced. Light half-inch strips, as long as the width of the car, are placed across the ends of the packages; and the front one is nailed down with a light nail to the head of each package, to prevent side shifting. Another row of packages is placed on these strips, each one directly above one in the lower row. These are again stripped and nailed, and BO en to the top. Th<» Associations and Pools. 471 next course is placed with the ends snugly against the ends of the first course, so that the air spaces are continuous. When the center of the car is reached, begin in the other end and load in the same way. A space will usually be left at the last, too narrow to admit another course of pack- ages; and the car must now be braced, to prevent the courses from shifting endwise. Pieces of one by six inch boards are set up against the ends of each rank of packages, and other strips are nailed across these uprights, near the bottom and the top of the car. The distance between these opposite cross-pieces is now carefully measured, and pieces of board are cut for braces about an inch longer than this space, so that they will have to be driven home with con- siderable force. The braces are toe-nailed in place, to pre- vent their falling, if they should chance to loosen in the bumping of the car. When thus loaded and braced, the con- tents are absolutely immovable, yet each package is separated from its neighbors on all sides by a layer of cold air, which, when it becomes warmed by the hot fruit, rises, and is car- ried by the currents thus generated to the ice, where it is quickly cooled again, and where it deposits the moisture that may have been taken up from the fruit. This rapid circu- lation of the air is very important, and the ice, instead of making the fruit damp, as might at first be thought, really serves to dry it very effectually." Shipping associations. — In many parts of the country, the grower, if he is a good business man, can find a special market for all that he can raise ; but, in general, it is no doubt true that a thoroughly competent organization of fruit men is the best means through which to distribute fruit. Such an organization should make it a particular business to determine just where the best markets are, and to make out lists of those towns which are within practicable reach of the fruit region, with the popu- 472 The Principles of Fruit-growing. lation and the consuming capacity of each, the transportation rates thereto, and all incidental mat- ters which are likely to influence the market from day to day. Having such information before it, the association, if it has the shipping of the larger part of the fruit of any region, can place such quantity in each city or town as can be consumed, and thereby prevent the glutting of the markets. All this can be done only when the system of organi- zation is exceedingly thorough and when the growers are willing to cooperate; but it would likely be a mistake for any organization to expect to enlist in such an enterprise those fruit-growers who are able to find special and personal markets for themselves, as indicated in the next paragraph. Such growers are ordinarily so few, however, that they do not influence the general market conditions. Much has been said during the past few years about the shipping of fruit in pools or unions. When the market is very far removed from the producer, so that transportation rates are high, an organization of interests is often necessary. In districts which are so far from markets as the Pacific coast, it is necessary that a man have either a large quantity of fruit to ship or that he ship in conjunction with his neighbors; or, that he sell his fruit outright to buyers. In districts which are close to market, it is rarely advantageous to the growers of the very finest fruits to ship through pools or unions. The difficulty is that the best fruit is sold for about the same price that the poor fruit Shipping in Pools. 473 is, and it is very rare that all the growers of any locality pack their fruit in the same degree of ex- cellence. If the union were to exercise very strin- gent oversight over the packing, this difficulty might be overcome. If, for example, the fruit were brought to the union in the trays or crates directly from the field, and were then re -packed uniformly before shipment, and each grower paid for the exact amount of good fruit which he delivers, the union might prove to be very advantageous, because there should !>•• an economy in the purchase of baskets, in the cost of packing, in transportation rates, and also in the finding of the best markets. The unsatisfactory results which have arisen from fruit unions have not come from inherent difficulties in the system so much as from the lack of a thorough business system of oversight to the packing and grading of all the different samples which are submitted. The number of persons who can and will grow a dessert quality of fruit is very few, and such I id-sons can really not afford to pool their interests with the common run of fruit-growers. These per- sons are the ones who find special markets here and there, and they should use special and personal means of disposing of their produce. The more cities there are within a given distance, and the greater the number of transportation lines, the greater are the chances that a man will be able to find a personal and special market for his produce. An illustration of a fruit market. — A knowledge of the destination of fruit after it reaches a 474 The Principles of Fruit-growing. metropolis should aid growers and shippers in com- prehending the needs of the market. The following is a graphic description of fruit -selling in Chicago:* "The distribution of the supplies furnished by the fruit-grower, whether direct or through the agency of others, has gradually become a complex and complete system. Perhaps I ought not to use the term 'complex,' as each step is well defined and, after all, simple, but I think but few fruit- growers have any idea of how complete it is, and to what distances fruit is exported, — the only limit being the cost and ability of the consumer to pay prices commensurate with the expenses and risks. "Practically all receipts are taken from the depots or docks to the various places of business as early as practicable after the arrival of the train or steamer. To make the matter clearer, let us illus- trate by using letters in place of names. A, a shipper, consigns to B, his correspondent, a ship- ment of fruit. On arrival, B has his spring wagons in waiting, and takes it to his place of business on South Water street. There, with other lots of fruit of different grades, qualities and conditions, it is examined and offered for sale. The largest, finest, and every -way -select lots are taken by the retail grocers whose patronage is among the 'upper ten,' to whom money is no object, apparently. The grade must be of the very best, quality superior and con- dition perfect. Less than 5 per cent of the total *Mr. Barnett, of Barnett Bros., before Mich. Hort. Soc., Dec., 1896, as re- jiorted in the Horticultural Gazette, Allegan, Mich., for Dec. 19, 1896. The Chicago Market. 475 receipts meets the conditions exacted, so that the amount that can be disposed of to this class of buyers is limited, and their requirements are also about in the same proportion "The next grade is of really good quality and good condition, so that it can be handled with a reasonable degree of safety, and good for, say, twenty -four hours' transit to other points, or to be handled safely by the average retail grocer who supplies the well-to-do classes. The competition for this class of fruit is the greatest, and often a sale turns on the condition only, the shipper often turn- ing from a good line of fruit and accepting some- thing not so desirable in quality, to secure that which will reach his customers in good condition. It is very much better to have a medium grade of quality in good condition than a fancy line of fruit as to flavor, size, etc., worthless on account of de- cay. That fruit which lacks the carrying qualities desired by the shipper is just right for the retail dealer, and, as a rule, will class good to choice. "There are then left the inferior grades, both as to quality and condition. For these, buyers are found among the grocery keepers in the poorer sec- tions of the city, — among the foreign populations. They are good judges of fruit, and buy to meet the wants of their customers. With them, also, there are the peddlers, a numerous class and an influen- tial one, whose trade is necessary in handling large receipts. These latter also use the refuse, the 'off condition' of all grades, and the poorest qualitie* 476 The Principles of Fruit-growing. that arrive, or that become in poor condition after arrival, as well as a respectable portion of the better grades, for they sometimes carry a very good quality. " Let us trace these different classes a little further, bearing in mind carefully that there is no arbitrary grading, the perishable qualities of fruit at times making the 'fancy' of 5 A. M. the 'peddler's- stock' at 5 P. M. Let us suppose C is a retail dealer having the best patronage. He selects what he needs (carefully paying no more than he can help— which remark also applies to all), has it set aside, and sends .his wagon for it as soon as he has completed his purchases. Arriving at his store, the fruit is temptingly displayed to catch the eye, and from his stock he fills his orders, taken often with- out the price being named in advance, quality being the chief requirement, sends to his customer, and charges it up to his account. The transaction is completed— all but collecting the bill. Many pay; many do not, and during the last thirty years, of all I have known, in the strictly fancy trade, less than a dozen have earned a competence. But little net profit remains with them. "The retail dealer, D, who supplies the middle classes, with a fair proportion of the well-to-do, loads his purchase into his wagon, and at once goes home to be ready for dinner, placing a moderate advance on his purchase price as his selling figure. He sells for cash if he can, or to his 'book.' cus- tomers at practically the same figure. He delivers to his customer's home, if desired, but the bulk of Description of a Mark ft 477 it is taken at the time of purchase, ami he clears out his stock as closely as possible. The advance charged by the retailer for his labor of selecting, selling, delivering, and collecting his accounts may be roughly estimated at 2 cents per box on small fruits, and 2 cents per basket on peaches and 5 cents per peck on apples. This must cover the loss by decay, sampling, etc., inevitable to the retail trade. At times, when fruit is scarce, the profit charged will be larger, and when abundant, less. Sometimes a 'run' is made, and a single dealer will buy one hundred to three hundred baskets and sell at cost, but I consider this as advertising. "E, the peddler or huckster, buys everything left. It may be 'fancy,' or 'good,' 'out of condition,' 'scrubs,' 'trash' — anything is grist for his mill.

Taking their purchases into their wagons, they at once start for their routes and cry their wares. There can be no fixed margin. They get what they can, take a margin, or sell at cost ; live on the refuse, and prob- ably have only a dollar per day on which to sup- port a family.

There is not a lane, street, nor avenue of the city where their voice is not heard, not a block but is visited by their ram- shackled old wagon, their apology for a horse with his harness or straps and strings. Not a house is passed unnoticed ; they are everywhere, and sell the fruit at a margin so close that, as I have said, their profits are exceedingly small. I honor them, for they are engaged in an honest calling ; I respect them, for they bring to the very poor, in the poor- est sections of the city, a taste, at least, of the richest and best offering of the country to the city, and we use them freely in our business and treat them, rough, uncouth, ragged and ignorant though they may be, as men. "There remains F, the shipper, whose aid is val- uable in the disposition of the receipts from day to day. His selections have been made on the basis of his orders in hand or in prospect. He has carefully studied the country that can be reached from this city, and by a course of correspondence or personal interview has built up a clientage that orders from him in such quantities as may be sold profitably. The entire northwest has been carefully studied, and from central Illinois to middle Missouri, western Iowa, central 'Minnesota, and all of Wisconsin, orders have been solicited and some have been received. Weekly quotations are sent, some houses sending two thousand to three thousand at a single issue. These reach every city, town, village, or hamlet within reasonable rail communication, and everything else is Description of Fruit -selling. 479 out of the question. He studies the needs of each customer, and having secured the amount needed to fill his orders, at once commences to send by ex- press, and to many points where through freights run the fruit goes largely in that manner. It is safe to say that there is no spot within two hundred miles of Chicago that, with fair means of connection with this market, can not have a full supply of fruit. "Now, as to the expense or cost of these ship- ments. The broker, dealer or shipper is well satis- fied if he can realize 10 per cent on his purchases. Let the shipper of fruit to this market consider what it means. There is the careful selection of fruit, the marking, billing, practically guaranteeing of safe de- livery, chances of failure of his far-off customer — and collecting his bill at the end of two weeks to three months. Applying the test to the fruit broker or shipper, but few get much more than a living out of the business. The express and freight companies charge only a fair compensation for the service per- formed. Although fruit may come high in central Minnesota or northern Wisconsin, the dwellers in those regions can not reasonably expect to have fruit brought to them without labor and expense." APPENDIX. /. HOW DID THE VARIETIES OF FRUITS ORIGINATE? There Is universal curiosity to know how the various kinds of fruits have originated. It seems to be next to impossible to en- lighten the public mind upon the question, for whatever detailed ex- planation one may give seems to leave the questioner unsatisfied. The real cause of this dissatisfaction is the fact that people assume that there is something mysterious about the process of the origi- nation of varieties; and so long as the mind makes a mystery of a subject it is impossible to elucidate it. We have also been taught that like normally produces like, and therefore that any unlikeness between two plants — as between the parent and its off- spring—calls for instant explanation. The fact is, that it is not the nature of domestic productions for like to produce like, but rather for similar to produce similar. That is, there are certain type or family characteristics which . pass over to the offspring, but there is normally almost endless unlikenesses in the details. Apples give rise to apples, and sometimes- there is a closer reproduction of the parents in tribes like the Fameuse apples and the Crawford peaches; but there is seldom or never an exact duplication of pa- rental features. Considering that this is the normal law of nature, it follows that the wonder is that plants should ever reproduce the variety with approximate exactness. In other words, rigidity of generation may be the thing to be explained rather than the elas- ticity of it. In kitchen-garden vegetables this rigidity has come about, but it is the direct result of a long effort at selection and breed- ing until the elasticity of the type has been largely bred out.* *A fuller explanation of this class of facts will be found on pages 88, 89 and 90 of "Plant-Breeding;" and the reader is referred to that work and to "The Survival of the Unlike" for discussions of the philosophy of plant-breeding and of the running out of varieties. PF (481) 482 Appendix. Those persons who are always wondering how the varieties of fruits have come should consult the records. History is capa- ble of enlightening them. If the origins of varieties are traced it will be found that in the vast majority of cases the variety was simply discovered, and that some one began to propagate it because he thought it to be good. A tree springs up along a roadside, in the fence-row, back of the barn, in a thicket, and bears acceptable fruit. It is the product of a chance seed dropped by a bird or thrown there by an urchin. A thousand, perhaps ten thou- sand, seeds produce trees which bear poor or indifferent products where only one bears superior fruit. This one good tree is cherished, and all the others are forgotten, or perhaps are never seen ; and then we wonder why so many more good varieties originate in the half-wild places than in the garden. It is only because more seeds have been sown there ; and as we do not covet the ground, the failures pass unnoticed. If we should secure the same results in the garden by the sowing of only half the number of seeds, we should consider the experiment to be a costly one. It is probable that a seed will produce the same character of fruit, whether the tree springs up in a fence-row or in the garden ; and the half- wild areas are, therefore, most useful and prolific places in which to allow nature to carry out her various whims in plant-breeding. And if man has been willing to be relieved of all effort in the matter, it is fair to assume that he will long continue of the same mind, and that this exploration for new varieties will be a passion of the adventurer until every copse and tangle has been razed into cultivated fields. There has been, to be sure, an occasional direct attempt to pro- duce new varieties, but there has been very little definite plant- breeding of the type which sets an ideal before the mind and then tries to attain to it. It is not germane to the present book to dis- cuss the fundamental reasons why plants vary and new forms arise. These reasons are obscure at best, but the greater part of them are probably not past finding out. It is enough for this occasion to say that nearly all the varieties of fruits were seedlings found in some waste place, or in a nursery row or a garden ; and they were propagated. Apprmlis. 483 //. REMARKS ON CLASSIFYING AND DESCRIBING FRUITS. We name the varieties of fruits in order that we may speak and write about them. Since the name is a definite thing, it is commonly assumed that the variety is also a definite thing. It is a fact, however, that varieties are not definite or definable. This follows from two facts, —that there is no original or necessary standard or measure of what shall constitute a variety, and that the variety may vary or change through the influence of climate or other agencies. There are, there- fore, varieties representing all degrees of differences, some being so unlike all others as to be universally accepted as distinct, and some so like others as to cause dispute as to whether they are really varieties or not. Again, we must not assume, because one name has been retained for a certain stock, that the stock, therefore, remains the same. For example, the fact that we still use the name Catawba does not prove that the Catawba grape is the same now as it was when first named and disseminated; the King is not the same apple in Oregon and New York, although the name is the same in both states, and all the trees have been propagated from one original. These remarks are made for the purpose of pointing out the facts that the classifying and describing of varieties involve two classes of problems,— the questions connected with the making of the names and the systems (as the form of the name, rules of priority, schemes of classification), and those associated with the natural history of varieties (as to whether given varieties are distinct, the value of geographical names and synonyms, and the like). The practical ap- plication of these remarks is, that we are not to expect uniform exactness, either in the classifying of varieties or in the describ- ing of them. We can deal only with types, expecting that numerous exceptions will be found to the most painstaking description, and to the most carefully made key. Varieties are not entities or things, as machines are, a fact which, though usually not recognized, has been the reason for the failure of the many attempts to protect the originator of varieties by means of patent rights. The first step in making a sketch of a variety is to distinguish clearly between a description and a characterization. A description gives a full account of all the attributes; a characterization gives only those attributes which are unique to the variety. For example, ten kinds of cherries may be large, red and heart-shaped; in descrip- tions, these three attributes are repeated for each variety; but in 484 Appendix. characterizations, these attributes are omitted (having previously been given in a general sentence), and only those features are mentioned which distinguish any variety from the other nine. It follows that when varieties are arranged alphabetically, only descriptions are of value; but when they are arranged in some system of classification, only characterizations are admissible. Descriptions are easy to make: one writes down what he sees. Characterizations are difficult to draw: one must make comparisons of many specimens, and he must clearly perceive an ideal type. In making either descriptions or characterizations, the student should consider the entire plant as well as the fruit itself. The habit of growth, the bark and foliage, the flowers, often have characteristic features in different varieties. Yet, since the fruit is the main con- sideration, and since the enquirer can seldom have flowers and fruits at the same time, and often has not even access to the plant, it must follow that characters drawn from the fruit itself must form the foundation of the characterization; and these should usually precede other characters in the paragraph. Similarly, a system of classifica- tion of the varieties of any fruit which gives great emphasis to char- acters not drawn from the fruit itself, is fundamentally weak. It is to be expected, therefore, for example, that the effort to classify varieties of apples and pears by characters of the stamens and styles will never come into popular use; but these characters are no doubt of great value if they can be used as secondary features of descrip- tions or characterizations. For studies of the characters of stamens and styles in pomaceous fruits, see Beal's various writings. (Rep. Mich. Pom. Soc. 1876, 17. Am. Pom. Soc. 1877; 1879, 27; 1881, 73.) Of ideals of classification founded on the characters of the fruit, one of the best discussions is to be found in Hogg's "Fruit Manual" (English). The student should also consult Warder on "The Apple," and Thomas' "American Fruit Culturist." Since each fruit demands a separate and usually distinct mode of classification and characterization, the details of the subjects cannot be considered here; but the following extracts will show what consti- tutes a complete and good description in the mind of one careful stu- dent (Real, Proc. 12th and 13th Ann. Meetings Soc. Prom. Agric. Sci., 1892, pp. 25, 28) : « Crescent Strawberry. — Plant rather large, not robust, soft pubes- cent, of a light green color, very hardy and vigorous and exceedingly productive; runners rather slender, bracts a little above the middle; leaflets slightly involute-conduplicate, oval, coarsely serrate or rarely Appendix. 485 doubly serrate; peduncle rather stout, raising the panicle nearly as high as the leaves; panicle 2-4 inches long, 12-24-flowered (usually about 15-flowered); lower bracts broad, oval; sepals lanceolate or ovate-lanceolate, the alternating bractlets about the same length; petals orbicular, or oval, 4-16 to 5-16 inches long, including a short claw; stamens numerous and well developed; fruit bright crimson, broad ovoid to round oblong, % inch long; moderately firm; quality, medium; season medium. "Origin, Connecticut, 1870. "Probably not excelled by any variety for its productiveness on all sorts of soils and with every kind of treatment. Extensively grown." "Cuthbert Raspberry. — Pl&nt tall, stout, slightly glaucous, prickles recurved, few, weak, seldom more than one mm. long; leaves, some- what wrinkled, light green above, light green to glaucous green below, under a lens more or less tomcntose; leaflets large, doubly serrate-dentate, often recurved, those on stout shoots' mostly five, sessile, puckered at the base, those of bearing branches three, stipules 45 mm. long, erect, terete, 7-10 of the upper leaves bearing 1-4 flowers, light red on the upper side, pedicles 1.5-2.5 cm. long (the whole panicle 20-30 cm. long), smooth or with minute prickles, bractlets 1-2 mm. long; calyx destitute of prickles, petals narrowly oval or obovate, 4-5 mm. long, including the very short claw; pistils clothed with minute reddish pubescence; fruit ovoid-conic, 6-8 mm. long; base of calyx 3-5 mm. long; styles, when dead, brown, bent, 2.5 mm. long; torus conical, 8 mm. long, fruit red, very large and firm, productive and vigorous, quality good, rather hardy, season medium. "Origin, New Jersey or New York, 1870." A glossary of some of the leading terms used in describing fruits may be useful to the novice. Of general terms, the following may be mentioned: Phytography, the describing of plants; taxonomy, the science or practice of classification; terminology, the knowledge of the terms or technical words used in any subject; nomenclature, the knowledge of the names used to designate any class of objects. Leading terms used to designate the shape of fruits are as fol- lows: Conical, length equal to or greater than the breadth and the upper shoulders narrowed (Fig. 115); ovate, broader than the conical (Fig. 116); obovate, inversely ovate (larger at the apex); oblong, length equal to or greater than the breadth, and sides parallel or very nearly so; oblate, distinctly flattened endwise (Fig. 117); lop-sided (Fig. 118). Combinations of these terms with themselves (Fig. 119), Fig. 118. Lop-sided. Appendix. 487 and with such common adjectives as spherical, round, short, flat, enable one to designate the form of the more irregular fruits. The ends or extremities of fruits are described by technical terms. In pome-like fruits, the depression in the apex (or blossom end) is known as the basin (d, e, Fig. 120). The depression at the base (or stem end) is the cavity (a, b, c, Fig. 120). The basin is broad and deep in e, and small and shallow in d; and it is corrugated or fur- rowed in Fig. 117. The cavity is narrow and deep in a, broad and deep in c, and narrow and shallow in b. In the basin sits the calyx or eye. This calyx is open in e, and closed in d. The stalk or stem is short in a, very short in 6, and long and slender in c. In stone- fruits, the depressions at apex and base are less marked, and the term basin is not used; but cavity is used for the depression about the stem. The longitudinal furrow or depression on the side of a stone-fruit (as of a peach or plum) is known as a suture. In describing the color of a fruit, it is customary to assume an under-color or ground-color, which is laid on nearly or quite uni- formly over the entire surface, and over which the markings are dis played. This ground-color is therefore the prevailing tone of yellow or green, or other subdued color, which shows between the spots and streaks, underneath the solid red or purple, and on the uncolored side of the fruit. A fruit is striped when it is marked by broad and more or less definite longitudinal bands; streaked when the markings are very narrow, as in Fig. 115; splashed when the stripes are broken and irregular; mottled when marked by large confluent dots. The quality of a fruit is determined by its texture and its flavor. The texture is said to be hard, coarse, gritty, rough, fine-grained, buttery, melting. The flavor is described as poor, good, very good (largely matters of individual taste), sweet, acid or sour, subacid or nourish (that is, only slightly sour), dry, juicy, vinous (with a lively wine-like suggestion), aromatic, and the like. The names of varieties should be short and modest; and a name which has once been used should not be used again in the same class of fruit, even though the variety to which it was first applied should have become extinct. All titles, as General, Professor, President, and all extravagant adjectives, as superb, magnificent, grand, should be omitted from the name of the variety. The standard practice in this country is that specified in the rules adopted by the American Pomo- logical Society. Helpful suggestions may also be found in the rules adopted by a committee of horticulturists for the naming of vege- tables, and published in "Annals of Horticulture for 1889." 488 Appendix. III.

"It has the unique distinction of presenting for the first time, in a carefully arranged and perfectly accessible form, the best knowledge of the best specialists in America upon gardening, fruit-grow- ing, vegetable culture, forestry, and the like, as well as exact botanical information. . . . The contributors are eminent cultivators or specialists, and the arrange- ment is very systematic, clear and convenient for ready reference." "We have here a work which every ambitions gardener will wish to place on his shelf beside his Nicholson and his Loudon, and for such users of it a too advanced nomenclature would have been confusing to the last degree. With the safe names here given there is little liability to serious perplexity. There is a growing impatience with much of the controversy concerning revision of names of. organisms, whether of plants or animals. Those investigators who «re busied with the ecological aspects of organisms, and also those who are chiefly concerned with the application of plants to the arts of agriculture, horticulture, and so on, care for the names of organisms under examination only so far as these aid in recognition and identification. To introduce unnecessary confusion is a strious blunder. Professor Bailey has avoided the risk of confusion. In short, in range, treatment and editing, the Cyclopedia appears to be emphatically nsefnl: ... a work worthy of ranking by the side of the Century Dictionary."— The ffation.

H. BAILEY With delineations from nature by W. S. HOLDSWORTH, of the Agricultural College of Michigan SEVENTH EDITION-491 PAGES-446 ILLUSTRATIONS-12MO- CLOTH-Sl.10 NET There are two ways of looking at nature. The old way, which you have found so unsatisfactory, was to classify everything — to consider leaves, roots, and whole plants as formal herbarium specimens, forgetting that each had its own story of growth and development, struggle and success, to tell. Nothing stifles a natural love for plants more effectually than that old way. The new way is to watch the life of every growing thing, to look upon each plant as a living creature, whose life is a story as fascinating as the story of any favorite hero. "Lessons with Plants" is a book of stories, or rather, a book of plays, for we can see each chapter acted out if we take the trouble to look at the actors. "I have spent some time. in most delightful examination of it, and the longer I look, the belter I like it. I find it not only full of interest, but eminently sug- gestive. I know of no book which begins to do so much to open the eyes 'of the student— whether pupil or te:ieher-to the wealth of meanin • contained in simple plant forms. Above all else, it seems to be full of suggestions that help one to learn the language of plants, so they may talk to him."— DARWIN L. BARDWKLL, Superintendent of Schools, fiiiighamton. " It is an admirable bonk, and cannot fail both to awaken interest in the sub- ject, and to serve as a helpful and reliable guide to young students of plant life. It will, I think, fill an important place in secondary schools, and comes at an op- portune time, when helps of this kind are needed and eagerly sought."-Professor V. M. SPALDING, University of Michigan.

BAILEY TWELFTH EDITION- 431 PAGES-500 ILLUSTRATIONS-Sl . 10 NET "This book is made for the pupil: ' Lessons With Plants ' was made to supplement the work of the teacher." This is the opening sentence of the preface, showing that the book is a companion to "Lessons With Plants," which has now become a standard teacher's book. The present book is the handsomest elementary botanical text- book yet made. The illustra- tions illustrate. They are artistic. The old formal and unnatural Botany is being rapidly outgrown. The book disparages mere laboratory work of the old kind: the pupil is taught to see things as they grow and behave. The pupil who goes through this book will understand the meaning of the plants which he sees day by day. It is a revolt from the dry-as-dust teaching of botany. It cares little for science for science's sake, but its point of view is nature-study in its best sense. The book is divided into four parts, any or all of which may be used in the school: the plant itself; the plant in its environ- ment; histology, or the minute structure of plants; the kinds of plants (with a key, and descriptions of 300 common species). The introduction contains advice to teachers. "An exceedingly attractive text-book." -Educational Review. " It is a school book of the modern methods."— The Dial.
