A. HUNTER. York, June i, 1800. TO THE MEMORY OF JOHN EVELYN ESQUIRE A MAN OF GREAT LEARNING SOUND JUDGMENT AND MOST EXTENSIVE BENEVOLENCE. FROM AN EARLY ENTRANCE INTO PUBLIC LIFE TO AN EXTREME OLD AGE HE CONSIDERED HIMSELF AS LIVING ONLY FOR THE BENEFIT OF MANKIND. READER DO JUSTICE TO THIS ILLUSTRIOUS CHARACTER AND BE CONFIDENT THAT AS LONG AS THERE REMAINS A PAGE OF HIS NUMEROUS WRITINGS AND AS LONG AS VIRTUE AND SCIENCE HOLD THEIR ABODE IN THIS ISLAND HIS MEMORY WILL BE HELD IN THE UTMOST VENERATION. EDITOR'S PREFACE TO THE FIRST EDITION. J.T may appear a matter of singularity that a person of my Profefsion should engage in a work which, it must be confefsed, has but a small alliance with Medicine. But I wish to have it known, that, during the whole time this edition was under my hands, I considered it only as affording amusement, and relaxation from studies of a severer kind. To liberal minds this will be a sufficient apology : To persons of a different turn I have nothing to observe. Tacitus says, Ad utilitatem viLe omnia facta consiliaqne ?iostra sunt dirigenda : and I could produce proofs of the highest authority to confirm this excellent sentiment ; but an age eager in pursuit of natural knowledge needs no incitements. The expense attending this work would have deterred me from the prosecution of it almost as soon as begun, had it not been for a most distinguished Patronage, under whose recommendation the Subscription filled beyond my most sanguine expectations Since the first edition of the Silva, in 1664, many improvements have been made in planting, and in every branch of natural knowledge. It, there- fore, became my indispensable duty to bring down the improvements to the present time. These make the subject of the Notes, which are drawn from the most respectable authorities. I afsume no merit beyond the arrangement of the materials, having in all places preserved the Author's own words, excepting in cases where the sense was obscured by an impropriety of exprefsion. To join the language of so many different x THE EDITOR'S PREFACE. writers, so as to appear with the uniformity of one author, required at first a considerable degree of attention ; but the composition grew easy in proportion as the subject became familiar.. To the following Authors I stand particularly indebted : Sir Charles Linnjeus, the Rev. Dr. Stephen Hales, the Rev. Mr. Hart, Mr. Bradley, the Rev. Mr. Hanbury, Mr. P. Millar, Mons. Duhamel, Mons. Buffon, the Abbe Shabol, and Profefsor Kalm ; and I make this public acknowledgment to avoid the charge of plagiarism. The Philosophical Transactions of London, have, in many instances, been of singular service to me ; and I have had frequent occasion to introduce extracts from my own Georgical Efsays. I also acknowledge to have received much afsistance from James Farquharson, Esq. whose excellent Memoir upon the Cultivation of the Scotch Pine is inserted in the twenty-second chapter of the first book. Mr. Speechly, gardener to his Grace the Duke of Portland, by his Grace's orders, transmitted to me the account published in the first volume, describing the method of planting upon his Grace's estates in Nottinghamshire ; and I have great satisfaction in being authorised to say, that this most excellent planter has his Grace's permifsion to direct gentlemen in the manner of forming plantations for which he is well qualified in all the varieties of soil and situation. From the same judi- cious person I am favoured with the Note inserted at the end of the third chapter of the third book, describing a method of raising the pine apple without the use of tanner's bark. I wish to be known to have received favours from Joseph Banks, Esq. whose desire after natural knowledge is not confined within the limits of the habitable world*. * Vide A Voyage towards the North Pole, undertaken by the H6n. Capt. Phipps, in the year 1773. Introduction, p. 12. THE EDITOR'S PREFACE. xi His Grace the Duke of Portland lays me under the greatest obligation, by presenting this work with two most elegant views of the greendale oak. Mr. Grimm's delineation of this venerable Tree deserves the highest encomiums ; and I have great satisfaction in acknowledging the merits of Mefsrs. Rooker and Vivares, whose Engravings have done it all imaginable justice. Each View has its Skeleton annexed, that the excel- lence of the workmanship might not be injured by the Table of Mensu- ration. Mr. John Miller has shown great elegance and correctnefs in his department as a draughtsman and engraver ; and I am singularly obliged to Mr. Bartolozzi for the fine head of Mr. Evelyn, which stands an unrivalled monument of his excellence as an Artist. I beg leave to present my warmest acknowledgments to Sir John Rufsel, Bart, and to Thomas Frankland, Esq. for their friendly care in overlooking the artists in their different departments. Without their afsistance the plates would have been lefs worthy of the public appro- bation. I efleem myself greatly indebted to my most excellent and learned friend the Rev. Mr. Cappe, for his kind afsistance in the elucidation of several obscure pafsages and corruptions of the Text. Having explained my motives for undertaking this design, and acknow- ledged my obligations where due, either for civility or information, I have nothing left but to observe, that the liberties I have taken with the Text, in a variety of places, are warranted from a careful collation of the five editions with some Original Manuscripts, without which I could not pofsibly have proceeded with any degree of satisfaction : for of all the books in the English language, there are, perhaps, none so incorrect as the two last editions of the Silva : The one printed in 1704; the other in 1729. xii THE EDITOR'S PREFACE. Soon after the publication of the Silva, which made its appearance m 1664, under the auspices of the Royal Society, the spirit for planting- increased to a high degree ; and there is reason to believe that many of our ships which, in the last war, gave laws to the whole world, were constructed from Oaks planted at that time. The present age muft re- fle£t upon this with gratitude ; and it is to be hoped that we lhall be am- bitious to receive from Posterity the same acknowledgments that we, at this moment, pay to the memory of our virtuous Ancestors. A. HUNTER, York, August i, 1776. THE LIFE O F MR. JOHN EVELYN. J OHX EVELYN, the Author of this most excellent and laborious work, was born at Wotton in Surry, the seat of his father Richard Evelyn, Esq. upon the 31st. of October, 1620. He was descended from a very ancient and honourable family, which flourished originally in Shropshire; and was first settled at Wotton, in the reign of Queen Elizabeth. He was instructed in grammar and clafsical learning at the free-school at Lewes in Sufsex, from whence, in the year 1637, he was removed, and entered as a Gentleman-Commoner at Baliol College in Oxford. He remained there about three years, prosecuting his acade- mical studies with great diligence ; and then removed to the Middle- Temple in London, in order to add a competent knowledge of the laws of his country to his philological and philosophical acquisitions. Upon the breaking out of the Civil War, he repaired to Oxford ; where he obtained leave from King Charles I. under his own hand, to travel into foreign countries for the completion of his education. In the spring of 1644 he left England, in order to make the tour of Europe; which he performed very succefsfully, making it his businefs to inquire carefully into the state of the sciences, and the improvements made in all useful arts, wherever lie came. He spent some time at Rome, and happened to be there at the time of Laud's death, which gave him an opportunity of vindicating, in some measure, the memory of that honest, hut rash and zealous man. " I was at Rome," says Mr. Evelyn, " in the com- " pany of divers of the English fathers, when the news of the Arch- " bishop's sufferings^ and a copy of his sermon made upon the scaffold, " came thither. They read the sermon, and commented upon it, with c 14 THE LIFE OF " no small satisfaction and contempt ; and looked on him as one that " was a great enemy to them, and stood in their way, while one of the " blackest crimes, imputed to him, was his being popishly affected. " Mr. Evelyn visited also other parts of Italy, for the sake of improv- ing himself in architecture, painting, the knowledge of antiquities, me- dals, &c. His early affection to, and skill in the fine arts, appeared du- ring his travels ; for we findj that he delineated on the spot, the prospects of several remarkable places that lie betwixt Rome and Naples : more particularly, " The Three Taverns, or the Forum of Appius," mentioned in the Acts of the Apostles; " the Promontory of Anxur; a Prospect of " Naples from Mount Vesuvius ; a Prospect of Vesuvius, as it appears " towards Naples; the Mouth of Mount Vesuvius:" all which were en- graved from our Author's sketches by Hoare, an eminent artist at that time. He returned to Paris in the year 1647; where being recom- mended to Sir Richard Browne, Bart, the King's Minister there, he made his addrefses to his only daughter Mary, whom he soon after mar- ried, and by whom he became pofsefsed of Sayes-Court, near Deptford in Kent, where he resided after his return to England, which was about the year 1651. Some time before this he had commenced author; and the following pieces seem to be the first productions of his pen : — 1. " Liberty and Servitude." 1649, 12mo. Translated from the French. 2. " A Character of England, as it was lately presented in a letter to a " Nobleman of France, with reflections on Gallus Castratus." 1651, 16mo. The third edition of this book appeared in 1659; at present it is very scarce.— 3. " The State of France." 1652, 8vo. — 4. " An Efsay " on the first book of Lucretius, interpreted and made into English "Verse." 1656, 8vo. This translation was decorated with a frontis- piece, designed by his ingenious lady; with a panegyrical copy of verses by Mr. Waller, prefixed to it. — 5. "The French Gardener; instructing " how to cultivate all sorts of fruit-trees and herbs for the garden." 1658 and several times after. In most of the editions is added, " The English " Gardener vindicated, by John Rose, gardener to King Charles II. with " a tract of the making and ordering of wines in France." The third edition of the "French Gardener," which came out in 1676, was illu- strated with copperplates. — 6. " The Golden Book of St. Chrysostom, " concerning the education of Children." 1659, 12mo. MR. JOHN EVELYN. 15 The situation of public affairs induced Mr. Evelyn to live very retired at Sayes-Court ; and so fond was he of this rural retreat, that he seemed determined to enjoy retirement for life. This studious disposition, together with his disgust of the world, occasioned by the violence and confusion of the times, was so strong, that he actually proposed to Mr. Boyle the raising a kind of college for the reception of persons of the same turn of mind ; where they might enjoy the pleasure of society, and at the same time pafs their days without care or interruption. His letter to Mr. Boyle, in which the following plan of a college is contained, is dated the third of September, 1659, and exhibits an agreeable portrait of his philosophic and contemplative mind. " I propose the purchasing of thirty or forty acres of land, in some " healthy place, not above twenty-five miles from London ; of which a " good part should be tall wood, and the rest up-land pastures, or downs " sweetly irrigated. If there were not already a house, which might be " converted, &c. we would erect, upon the most convenient site of this, " near the wood, our building, viz. one handsome pavilion, containing a " refectorv, library, withdrawing-room, and a closet ; this the first story : " For we suppose the kitchen, larders, cellars, and offices, to be contrived " in the half-story under ground. In the second should be a fair lodging- " chamber, a pallet-room, a gallery, and a closet ; all which fliould be " well, and very nobly furnished, for any worthy person that might desire " to stay any time, and for the reputation of the college : The half-story " above for servants, wardrobes, and like conveniences. To the entry " fore-front of this court, and at the other back front, a plot walled in, of " a competent square for the common seraglio, disposed into a garden ; " or it might be only carpet, kept curiously, and to serve for bowls, " walking, or other recreations, &c. if the company please. Opposite to " the house, towards the wood, should be erected a pretty chapel; and, " at equal distances, even within the flanking walls of the square, six " apartments or cells for the members of the society, and not contiguous y Sca- . ligcr. Lib. i. fathers, ancient and venerable persons, who (as the excellent author of c- >■ Poet. * P. Beloni wrote in French, and his work here quoted, was turned into Latin by Car. Clusius, in 1539. Ed. 34 TO THE READER. the rites of the Israelites, chap. xv. &c. acquaints us) were not only obliged to instruct and inform their children of the wonderful things God had done for their ancestors, together with the precepts of the moral law, feasts, and religious ceremonies, but taught them likewise all that con- cerned Agriculture, joined with lefsons of perpetual practice, in which they were, doubtlefs, exceedingly knowing, whilst, during so many ages, they employed themselves almost continually in it: And though now-a- days this noble art be for the most part left to be exercised amongst us by people of grofser and unthinking souls, yet there is no science whatever which contains a vaster compafs of knowledge, infinitely more useful and beneficial to mankind, than the fruitlefs and empty notions of the greatest part of speculatists, counted to be the only eruditi and learned men. An Israelite, who, from tradition of his forefathers, his own experience, and some modern reading, had informed himself of the religion and laws which were to regulate his life, and knew how to procure things neces- sary; who perfectly understood the several qualities of the earth, plants, and places agreeable to each sort, and to cultivate, propagate, defend them from accidents, and bring them to maturity; that also was skilled in the nature of cattle, their food, diseases, remedies, &c. (which those who amongst us pafs for the most learned and accomplished gentlemen and scholars, are, for the most part, grofsly ignorant of, and look upon as base, rustic, and things below them,) is, in this learned author's opinion, infinitely more to be valued than a man brought up either in wrangling at the bar, or the noisy and ridiculous disputes of our schools, &c. To this sense the learned Modena. And it is remarkable, that after all that wise Solomon had said, " tbtit all was vanity and vexation of spirit," amono- so many particulars he reckons up, he should be altogether silent, and say nothing concerning husbandry; as, doubtlefs, considering it the most useful, innocent, and laudable employment of our life, requiring those, who cultivate the ground, to live in the country, remote from city- luxury, and the temptation to the vices he condemns. It was indeed a plain man, a potter by trade; but let no body despise him because a potter, (Agathocles, a king, was of that craft) who, in my opinion, has given us the true reason why husbandry, and particularly planting, is no more im- proved in this age of ours, especially where persons are lords and owners Palifsy, le of much land: " The truth is," says he, « when men have acquired any Moyen de de- ee collsideraMc fortune by their good husbandry and experience, (forgetting vemr Kiclie. TO THE READER. £3 " that the greatest Partriarchs, Princes, their sons and daughters, belonged " to the plough and the flock,) they account it a shame to breed up their " children in the same calling which they themselves were educated in, " but presently design them gentlemen. They must, forsooth, have a coat " of arms, and live upon their estates; so as by the time the son's beard is " grown, he begins to be ashamed of his father, and would be ready to " defy him that should, upon any occasion, mind him of his honest " extraction: And if it chance that the good man have other children " to provide for, This must be the darling, be bred at school and the " university, whilst the rest must to cart and plough with the father." " This is the cause," says my author, " that our lands are so ill cultivated " and neglected: Every body will subsist upon their own revenue, and " take their pleasure, whilst they resign their estates to be managed by " the most ignorant, the children whom they leave at home, or the " hinds to whom they commit them; when, as in truth and reason, the " more learning, the better philosophers, and the greater abilities they " pofsefs, the more and better they are qualified to cultivate and improve " their estates." Methinks this is well and rationally argued. And now you have in part what I had to produce in extenuation of this adventure : that, animated with a command, and afsisted by divers worthy persons, (whose names I am prone to celebrate with all just re- spects,) I have presumed to cast in my symbol; which, with the rest that are to follow, may, I hope, be in some degree serviceable to him (who- ever the happy person may be) that shall oblige the world with that complete system of Agriculture, which as yet seems a desideratum, and wanting to its full perfection. This, I afsure you, is one of the principal designs of the Royal Society, not in this particular only, but through all the liberal and more useful arts; for which, in the estimation of all equal judges, it will merit the greatest of encouragements; that so at last, what the learned Columella has wittily reproached, and complained of, as a defect in that age of his, concerning Agriculture in general, and is appli- cable here, may attain its desired remedy and consummation in this of ours. » Sola Res Rustica, quae sine dubitatione proxima, et quasi consan- P.^sTwLm; « guinea Sapienthe est, tarn discentibus egeat, quam magistris: Adhuc Stw recom- " enim Scholas Rhetorum, et Geometrarum, Musicorumque vel quod ™™^ "^ « magis mirandum est, contemptifsimorum vitiorum officinas, gulosius 5555? 56 TO THE READER. a.-ricobrm!r " condiendi cibos, et luxuriosius fercula struendi, capitumque et capillo- mihi ad sapi- « rum concinnatores, non solum esse audivi, sed et ipse vidi; Agricola- entis ritam . .„ r * . ° proxime vi- tionis neque Doctores, qui se prohterentur, neque Discipulos cognovi " dere.

There are divers learned and judicious men who have preceded me in this argument; as many, at least, as have undertaken to write and compile vast herbals and theatres of plants; of which we may have some of our own countrymen, (especially the most industrious and learned Mr. Ray,) who have boldly, I dare afhrm it, sur- pafsed any, if not all the foreigners that are extant. In those it is you meet with the discription of the several plants, by discourses, figures, names, places of growth, time of flourishing, and their medicinal virtues, which may supply any deficiency of mine as to those particulars; if, for" bearing the repetition, it should by any be imputed for a defect, though it were indeed none of my design. I say these things are long since per- formed to our hands ; but there is none of these (that I at least know of, and are come to my perusal) who have taken any considerable pains how to direct and encourage us in the culture of Forest-trees, the grand defect of this nation, besides some small sprinklings to be met with in Gervas Markham, Old Tufser; and, of foreigners, the Country-farm, long since translated out of French, and by no means suitable to our clime and country. Neither have any of these proceeded after my method, and so particularly in raising, planting, drefsing, governing, &c. or so sedulously made it their businefs to specify the mechanical uses of the several kinds, as I have done, which was hitherto a great desideratum, and in which the reader will likewife find some things altogether new and instructive ; together with directions and encouragements for the propagation of some foreign curiosities of ornament and use, which were hitherto neglected. If I have upon occasion presumed to say any thing concerning their medicinal properties, it has been modestly and frugally, and with chief, if not only, respect to the poor woodman, whom none, I presume, will TO THE HEADER. 37 envy, that, living Far from the physician, he should, in case of necefsity, consult the Reverend Druid, his Oaks*, and his Elm, Birch, or Elder, *NeSHva ..... ,. quidem, hor- for a short breath, a green wound, or a sore leg, casualties incident to his ridiorque na- hard labour.

The world is now advised, and, blefsed be God, infinitely redeemed from that base and servile submifsion of our noblest faculties to their blind traditions. This, you will be apt to say, is a haughty period ; but whilst I affirm it of the past, it justifies and does honour to the present industry of our age-; and of which there cannot be a greater and more emulous instance than the pafsion of his Majesty to encourage his subjects, and of the Royal Society, (his Majesty's Foundation) who receive and promote his dictates, in all that is laudable and truly emolumental of this nature. It is not therefore that I here presume to instruct him in the manage- ment of that great and august enterprize of resolving to plant and repair his ample forests, and other magazines of timber, for the benefit of his Royal Navy, and the glory of his kingdoms; but to present to his Sacred Majesty, and to the world, what advices I have received from others, observed myself, and most industriously collected from a studious propen- sity to serve as one of the least intelligences in the ampler orb of our illustrious Society, and in a work so necefsary and important. F S8 TO THE READER. And now, since I have mentioned the Society, give me leave, worth/ reader, as a member of that body which has been the chief promoter cf this ensuing work, to vindicate (as I stand obliged) that afsembly, and consequently the honour of his Majesty and the nation, in a particular which concerns it, though in appearance, a little foreign to the prefent subject. I will not say that all which I have written in the several paragraphs of this treatise is new; but that there are very many new and useful things and observations, (without insisting on the method only,) not hitherto delivered by any author, and so freely communicated, I hope will sufficiently appear. It is not therefore in behalf of any particular which concerns myself that I have been induced to enlarge this preface ; but, by taking this occasion, to encounter the unsufferable boldnefs or ambition of some persons, as well strangers as others, arrogating to them- selves the being inventors of divers new and useful experiments, justly attributable to several members of the Royal Society *. So far has that Afsembly been from affecting glory, that, they seem rather to have declined their due; not as ashamed of so numerous and fair an offspring; but as abundantly satisfied that, after all the hard mea- sure and virulent reproaches they had sustained for endeavouring, by united attempts, and at their own charges, to improve real philosophy* they had, from time to time cultivated that province, in so many useful * Consult the History of the Royal Society and their registers. The laws of motion, and the geometrical streightening of curve-lines, were first found out by Sir Christopher Wren and Mr. Thomas Neile. The equated isocrone motion of the weight of a circular pendulum in a paraboloeid, for the regulating of clocks, and the improving pocket watches by springs applied to the balance, were first invented and demonstrated to this Society by Dr. Hooke ; together with all those new and useful instruments, contrivances, and experi- ments mathematical and physical, published in his posthumous works by the most accom- plished Mr. Waller, Secretary to the Royal Society; and since, thofe of the incomparable learned Sir Isaac Newton, now President of the Royal Society ; Mr. Halley, the worthy Profefsor of Geometry in the University of Oxford; Dr. Grew, and several more, whose works and useful inventions sufficiently celebrate their merits. I do not mention the Barometer, to which might be added the prodigious effects of the Speculum Ustorium, surpafsing what the French confidently, or rather audaciously, pretend to; nor the other admirable inventions, injuriously arrogated by strangers, though due of right to English? men, and members of this Society; for it is not the businefs of this preface to enumerate ail, though it was necefsary to touch on some instances. TO THE READER. $r> and profitable Instances as are already published to the world, and will be easily afserted to their authors before all equitable judges. This being the sole inducement of publishing this apology, it may not perhaps seem unseasonable to disabuse some, otherwise, well-meaning people, who, led away and perverted by the noise of a few ignorant and comical buffoons, (whose malevolence or impertinences entitle them to nothing that is truly great and venerable,) are, with an insolence suitable to their understanding, still crying out, and asking, What have the Society done ? Now, as nothing lefs than miracles (nor those, unlefs God should every day repeat them at the call of these extravagants) will convince some persons of the most rational and divine truths, already so often and extra- ordinarily established, so neither will any thing satisfy these unreasonable men, but the production of the Philosopher's Stone and Great Elixirs which yet were they pofsefsors of, they would consume upon their luxury and vanity. It is not, therefore to gratify these magnificent fops, whose talents reach but to the adjusting of their peruques, courting a mifs, or at the farthest, writing a smutty or scurrilous libel, which they would have to pafs for genuine wit, that I concern myself in these papers; but, as well in honour of our Royal Founder, as the nation, to afsert what by other countries has been furreptitiously arrogated, and by which they not only value themselves abroad, but, prevailing on the modesty of that industrious afsembly, seek the deference of thofe who, whilst it remains still silent, do not so clearly discern this glorious plumage to be purely asckitious, and not a feather of their own. But still, what have they done ? Those who perfectly comprehend the scope and end of that noble Institution, which is to improve natural knowledge, and enlarge the empire of operative philosophy, not by an abolition of the old, but by the real effects of the experimental, collecting, examining, and improving their scattered phaenomena, with a view to establish even the received methods and principles of the schools, as far as were consistent with truth and matter of fact, thought it long enough that the world had been imposed upon by that notional and formal way of delivering divers systems and bodies of philosophy, falsely so called, beyond which there was no more country to discover; which being brought to the test and trial, vapours all away in fume and empty sound. F2 40 TO THE READER. This structure then being thus ruinous and crazy, it is obvious what they were to do; even the same which skilful architects do every day before us; by pulling down the decayed and sinking wall, to erect a better and more substantial in its place. They not only take down the old, reject the uselefs and decayed, but sever such materials as are solid, and will serve again; bring new ones in, prepare and frame a model suitable to so magnificent a design : This Solomon did in order to the building of the material temple ; and this is here to be pursued in the intellectual: Nay, here was abundance of rubbish to be cleared, that the area might be free ; and then was the foundation to be deeply searched, the materials accurately examined, squared, and adjusted before it could be laid : Nor was this the labour of a few ; lefs than a much longer time, more cost and encouragement than any which the Society has yet met withal, could not in reason be sufficient effectually to go through so chargeable a work, and highly necefsary. A long time it was they had been surveying the decays of what was ready now to drop in pieces. Whatever show the outside made with a noise of elements and qualities, occult and evident, abhorrence of vacuum, sympathies, antipathies, substantial forms, and prime matter courting form; epicycles, Ptolemean hypothefis, magisterial definitions, peremptory maxims, speculative and positive doctrines, and alti-sonant phrases, with a thousand other precarious and unintelligible notions, (all which they have been turning over to see if they could find any thing sincere and useful among this pedantic rubbish, but in vain,) here was nothing material, nothing of moment, mathematical or mechanical, and which had not been miserably sophisticated, on which to lay the strefs; nothing in a manner whereby any farther progrefs could be made, for the raising and ennobling the dignity of mankind in the sublimest operations of the rational faculty, by clearing the obfcurities, and healing the defects of most of the physiological hypotheses, repugnant, as they hitherto seemed to be, to the principles of real knowledge and experience. Now, although it wras neither in their hopes or in their prospect to consummate a design requiring fo mighty aids, environed as they have been with these prejudices, yet have they not desisted from the enterprize; but rather than so noble and illustrious an undertaking should not proceed for want of some generous and industrious spirits to promote the work,, they have themselves submitted to those mean employments of digging TO THE READER. 41 in the very quarry; yea, even of making brick where there was no straw but what they gleaned, and lay dispersed up and down ; nor did they think their pains yet ill bestowed, if, through the afsiduous labour and a train of continual experiments, they might at last furnish, and leave solid and uncorrupt materials to a fucceeding and more grateful age, for the building up a body of real and substantial philofophy, which should never fuccumb to time, but with the ruins of nature, and the world itself. In order to this, how many, and almost innumerable, have been their trials and experiments, through the large and ample field both of art and nature ! we call our journals, registers, correspondence, and transactions to witnefs; and may, with modesty, provoke all our systematical methodists, natural historians, and pretenders, hitherto extant from the beginning of letters to this period, to show us so ample, so worthy, and so useful a collection. It is a fatality and an injury to be deplored, that those who give us hard words, will not first vouchsafe impartially to examine these particulars, since all ingenuous spirits could not but be abundantly satisfied, that this illustrious afsembly has not met so many years purely for speculation only; though I take even that to be no ignoble culture of the mind, or time mispent, for persons who have fo few friends, and slender obligationss to those who should patronize and encourage them: but they have aimed at greater things, and greater things produced. By emancipating and freeing themselves from the tyranny of opinion, delusory and fallacious shows, they receive nothing upon trust, but bring all things to the Lydian touch ; make them pafs the fire, the anvil and the file, till they come forth perfectly repurged, and of consistence. They are not hasty in pronouncing from a single, or incompetent number of experiments, the ecstatic 'Eiyxxa, and offer hecatombs; but, after the most diligent scrutiny, and by degrees, and wary inductions honestly and faithfully made, record the truth and event of trials, and transmit them to posterity. They resort not immediately to general propositions upon every specious appearance, but stay for light and information from particulars, and make report dc facto, and as sense informs them. They reject no sect of philosophers, no mechanic helps, except^no persons of men; but cheerfully embracing all, cull out of all, and alone retain what abides the test; that, from a plentiful and well- furnished magazine of true experiments, they may in time advance to solemn and established axioms, general rules and maxims ; and a structure may 42 TO THE READER. indeed lift up its head, fuch as may stand the shock of time, and render a solid account of the phamomena and effects of nature, the aspectable works of God, and their combinations ; so as, by causes and effects, certain and useful consequences may be deduced: Therefore they do not fill their papers' with transcripts out of rhapsodists, mountebanks, and compilers of receipts and secrets, to the lofs of oil and labour; but, as it were eviscerating nature, disclosing the resorts and springs of motion, have collected innumerable experiments, histories, and discourses, and brought in specimens for the improvement of Astronomy, Geography, Navigation, Optics 3 all the parts of Agriculture, the Garden, and the Forest; Anatomy of Plants and Animals; Mines and Ores; Measures and Equations of Time by accurate Pendulums and other Motions; Hydro and Hygro-Statics, divers Engines, Powers, and Automata; with innumerable more luciferous particulars subservient to human life ; of which Dr. Glanvil has given an ample and ingenious account in his learned efsay, and since in the posthumous works of Dr. Hooke, lately published by the most obliging Mr. Waller, already mentioned. This is, reader, what they have done, and they are but part of the materials which the Society have hitherto amafsed and prepared for this great and illustrious work ; not to pafs over an infinity of solitary and loose experiments subsidiary to it, gathered at no small pains and cost: for fo have they hitherto borne the burden and heat of the day alone ; sapping and mining to lay the foundation deep, and raise a superstructure, to be one day perfected by the joint endeavours of thofe who fhall, in a kinder age, have little else to do, but the putting and cementing of the parts together, which, to collect and fit, have coif, them so mush solicitude and care. Solomon indeed built the glorious Temple, but it was David provided the materials. Did men in thofe days insolently ask, What had he done in all the time of that tedious preparation? I beseech you, what obligation has the Royal Society to render an account of their proceedings to anywho^ire not of the body, especially when they carry on the work at their own expence amidst so many contradictions? It is an evil spirit, and an evil age, which, having sadly debauched the minds of men, seeks with industry to blast and undermine all attempts and endeavours that signify to the illustration of truth, the discovery of imposture, and its sandy foundation.

It is impofsible to conceive how so honest and worthy a design should have found so few promoters, and so cold a welcome in a nation whose eyes are so wide open.

This were indeed to consult an honest fame, and to embalm the memory of a greater name than any has yet appeared amongst all the benefactors of the disputing sects. Let it suffice to affirm, that, next to the propagation of our most Holy Faith and its appendants, (nor can his Majesty or the nation build their fame on a more lasting or a more glorious monument, the propagation of learning and useful arts having always survived the triumphs of the proudest conquerors and spillers of blood,) Princes have been more renowned for their civility to arts and letters, than to all their sanguinary victories, subduing provinces, and making those brutish desolations in the world to feed a savage and vile ambition.

Never had the Republic of Letters so learned and universal a corre- spondence as has been procured and promoted by this Society alone, as not only the casual transactions of several years, filled with instances of the most curious and useful observations, make appear ; but, as I said, the many nuncupatory epistles to be seen in the fronts of so many learned volumes.

I have but one word more to add to conciliate the favour and esteem of our own Universities to an afsembly of gentlemen, who, from them, acknowledge to have de.rived all their abilities for these laudable Under- takings : Whatever is shining in them of most Christian, moral, and other- wise conspicuous, they confefs as derived from that source and fountain, to which, on all occasions, they are not only ready to pay the tribute and obsequiousnefs of humble servants, but of sons and dutiful alumni.

Certainly, persons of right noble and subacted principles, who are lovers of their country, should be otherwise affected, and rather strive to encourage and promote endeavours tending to so generous a design, than decry it; especially when it costs them nothing but their civility to so many obliging persons, though they should hitherto have entertained them but with some innocent diversions. To conclude, we envy none their dues ; nay, we gratefully acknowledge any lights which we receive either from home or from abroad ; we celebrate and record the names of those who give them amongst our benefactors; recommend them to the public; and what we thus freely give, we hope as freely to receive. Thus have I endeavoured to vindicate the Royal Society from some aspersions and encroachments it hitherto has suffered, and showed under what weights and prefsure this palm does still emerge ; and if for all this I fall short of my attempt, I shall yet have this satisfaction, that though I derive no glory from my own abilities, sensible of my great defects, I shall yet deserve their pardon for my zeal to its prosperity. 3>IA020IA2 EdwSi/^etc; 7ra[>a.c«; rt'o^vi Yifiiv aum q of pvi; ; au %\ Sfpuv f/.lv jur) tsyvii' ray hi /Sexr/raK aoi fauvo/jLtvav «roif £^«, wc V7ro tv ©e« Tijuypivo; l/f rxvTriv tyiv toXjut jutjUVYiiro hi on iolr juh i/A/jiimK toT; ouirolg, ol hxtoc- ■yiKavIk <™ 7r{'oTt{>ov, vroi iti vrifW S otv/Aoioched out in "various directions, and have grown much faster than other similar plants, growing in the " same exposure in common air. This observation led me to conclude, that plants, " instead of affecting the air in the same manner with animal respiration, reverse the " effects of breathing, and tend to keep the atmosphere sweet and wholesome, when " it is become noxious, in consequence of animals either living and breathing, or " dying and putrefying in it. In order to ascertain this, I took a quantity of air, •' made thoroughly noxious, by mice breathing and dying in it, and divided it into two " parts ; one of which I put into a phial immersed in water ; and to the other (which " was contained in a glafs jar, standing in water) I put a sprig of mint. This was " about the beginning of August 1771, and after eight or nine days, I found that a mouse " lived perfectly well in that part of the air, in which the sprig of mint had grown, but "died the moment it was put into the other part of the same original quantity of air; " and which I had kept in the very same exposure, but without any plant growing in it. "This experiment I have several times repeated; sometimes using air in which animals " had breathed and died ; sometimes using air tainted with vegetable or animal putre*. " faction, and generally with the same succefs. Once I let a mouse live and die in a " quantity of air which had been noxious-, but which had been restored by this procef^ " and it lived nearly as long as I conjectured it might have done in an equal quantity of " fresh air; but this is so exceedingly various, that it is not easy to form any judgment " from it; and in this case the symptom of difficult ra/iiration seemed to begin. earlier than " it would have done in common air. Since the plants that I made use of manifestly " grow and thrive in putrid air ; since putrid matter is well known to afford proper " nourishment for the roots of plants ; and since it is likewise certain that they receive u nourishment by their leaves as well as by their roots, it seems to be exceedingly probable, " that the putrid effluvium is in some measure extracted- from the air, by means of the " leaves of plants; and therefore that they render the remainder more tit for respiration. " Towards the end of the year some experiments of this kind did not answer so well as " they had done before, and I had instances of the relapsing of this restored air to its " former noxious state : I therefore suspended my judgment concerning the efficacy of " plants to restore this kind of noxious, air, till I should have an opportunity of repeating " my experiments, and giving more attention to them. Accordingly I resumed the "experiments in the summer of the year 1772, when I presently had the most " indisputable proof of the restoration of putrid air by vegetation ; and as the fact is of "•some importance, and the subsequent variation in the state of this kind of air is a litrte "remarkable, I think it necefsary to relate some of the facts prefty circumstantially. 22 .

The same you may also do for ruder hand- " The air, on which I made the first experiments, was rendered exceedingly noxious by " mice dying in it on the 20th of June. Into a jar nearly filled with one part of this air, " I put a sprig of mint, while I kept another part of it in a phial, in the same exposure ; f* and on the 27th of the same month (and not before) I made a trial of them, by intro- " ducing a mouse into a glafs vefsel, containing 1\ ounce measures filled with each kind " of air ; and I noted the following facts. When the vefsel was filled with the air in ft which the mint had grown, a very large mouse lived five minutes in it, before it began to " show any sign of uneasinefs. I then took it out, and found it to be as strong and " vigorous as when it was first put in; whereas in that air which had been kept in the " phial only, without a plant growing in it, a younger mouse continued not longer than " two or three seconds, and was taken out quite dead. It never breathed after, and was " immediately motionlefs. After half an hour, in which time the larger mouse (which I " had kept alive, that the experiment might be made on both the kinds of air with the " very same animal) would have been sufficiently recruited, supposing it to have received " any injury by the former experiment, was put into the same vefsel of air; but though it " was withdrawn again, after being in it hardly one second, it was recovered with "difficulty, not being able to stir from the place for near a minute. After two days, I " put the same mouse into an equal quantity of common air, and observed that it continued " seven minutes without any sign of uneasinefs ; and being very uneasy after three " minutes longer, I took it out. Upon the whole, I concluded that the restored air wanted " about one fourth of being as wholesome as common air. The same thing also appeared -" when I applied the test of nitrous air. In the seven days, in which the mint was " growing in this jar of noxious air, three old shoots had extended themselves about three " inches, and several new ones had made their appearance in the same time. Dr. Franklin " and Sir John Pringle happened to be with me, when the plant had been three or four " days in this state, and took notice of its vigorous vegetation, and remarkably healthy "appearance in that confinement. On the 30th of the same month, a mouse lived " fourteen minutes, breathing naturally all the time, and without appearing to be much " uneasy, till the last two minutes, in the vefsel containing two ounce measures and a " half of air which had been rendered noxious by mice breathing in it almost a year " before, and which I had found to be most highly noxious on the 19th of this month, a " plant having grown in it, but not exceedingly well, these eleven days; on which " account I had deferred making the trial so long. The restored air was effected by a '' mixture of nitrous air, almost as much as common air. As this putrid air was thus easily "restored to a considerable degree of fitnefs for respiration, by plants growing in it, I OF FOREST-TREES. 23 lings by burying your seeds in dry sand, or pulverised earth, barrelling chap. them, as I said, in tubs, or laid in heaps in some deep cellar, where the ^-^^v rigour of the winter may least prejudice them; and I have filled old hampers, bee-hives, and boxes with them, and found the like advantage; which is to have them ready for your Seminary, as before hath been showed, and exceedingly prevent the season. There be also who affirm, " was in hopes that by the same means it might in time be so much more perfectly " restored, that a candle would burn in it; and for this purpose I kept plants growing in " the jars which contained this air till the middle of August following, but did not take " sufficient care to pull out all the old and rotten leaves. The plants, however, had grown, " and looked so well upon the whole, that I had no doubt but that the air must constantly " have been in a mending state; when I was exceedingly furprised to find, on the 21th of " that month, that though the air in one of the jars had not grown worse, it was no better, " and that the air in the other jar was so much worse than it had been, that a mouse would " have died in it in a few seconds. It also made no effervescence with nitrous air, as it " had done before. Suspecting that the same plant might be capable of restoring putrid " air to a certain degree only, or that plants might have a contrary tendency in some " stages of. their growth, I withdrew the old plant, and put a fresh one its place; and " found that, after seven days, the air was restored to its former wholesome state. This "fact I consider as a very remarkable one, and well deserving of a farther investigation, M as it may throw more light upon the principles of vegetation. It is not, however, a " single fact; for I had several inrtances of the same kind in the preceding year; but it «' seemed so very extraordinary, that air should grow worse by the continuance of the " same treatment by which it had grown better, that, whenever I observed it, I concluded " that I had not taken sufficient care to satisfy myself of its previous restoration. That " plants are capable of perfectly restoring air injured by respiration, may, I think, be " inferred with certainty from the perfect restoration, by this means, of air which had " pafsed through my lungs, so that a candle would burn in it again, though it had. " extinguished flame before, and a part of the same original quantity of air still con" " tinued to do so. Of this one instance occurred in the year 1771, a sprig of mint having " grown in ajar of this kind of air, from the 25th of July to the 17th of August following; " and another trial I made, with the same succefs, the 7th of July, 1772, the plant having " grown in it from the 29th of June preceding. In this case also I found that the effect " was not owing to any virtue in the leaves of mint; for I kept them constantly changed. «' in a quantity of this kind of air, for a considerable time, without making anv sensible " alteration in it. These proofs of a partial restoration of air by plants in a state of " vegetation, though in a confined and unnatural situation, cannot but render it highly " probable, that the injury which is continually done to the atmosphere by the respiration " of such a number of animals, and the putrefaction of such mafses of both vegetable and " animal matter, is, in part at least, repaired by the vegetable creation. And, notwith- '* standing the prodigious mafs of air that is corrupted daily by the above-mentioned *' causes; yet, if A-e consider the immense profusion of vegetables upon the face of the u earth, growing in places suited to their nature, a*d consequently at full liberty to exert 24 A DISCOURSE that the careful cracking and opening of stones, which include the kernels, as soon as ripe, precipitate growth, and gain a year's advance ; but this is erroneous. Now, if you gather them in moist weather, lay them a drying, and so keep them till you sow, which may be as soon as you please after Christmas.

" all their powers, both inhaling and exhaling, it can hardly be thought, but that it may " be a sufficient counterbalance to it, and that the remedy is adequate to the evil. — " Dr. Franklin, who, as I have already observed, saw some of my plants in a very flourishing " state, in highly noxious air, was pleased to exprefs very great satisfaction with the *' result of the experiments. In his answer to the letter in which I informed him of it, " he says, " That the vegetable creation should restore the air ivhich is spoiled by the animal part of it, looks like a rational system, and seems to be of a piece with the rat. Thus fere purifies water all the world over. It purifies it by distillation, when it raises it in vapours, and lets it fall in rain; and farther still by filtration, when, keeping fluid, it suffers that rain to [tercolate the earth. We knew before that liutrid animal substances were converted into sweet vegetables, when mixed with the earth, and ahlilied as manure ; and now, it seems, that the same Jiutrid substances, mixed with the air, have «- similar effect. The strong thriving state of your mint injiutrid air, seems to show that the air is mended by takinv something from it, and not by adding to it." Experiments and Observations on different Kinds of Air, p. 86— 94. Vol. I. Every one who has a pleasure in contemplating and reflecting upon the wisdom of God in the creation, must be delighted with the harmony of the above system; but some foreign philosophers have lately introduced a new theory in hopes of destroying it entirely. They tell us that vegetables, during the day time, are continually perspiring through their leaves oxigene, or good air, and that in the night time, the same system of vefsels pour forth azote or impure air. If this kind of reasoning be founded upon correct experiment, we should form our plantations at some distance from our habitations, in order that these two opposite kinds of air may be well mixed with the surrounding atmospheric air before they find their way into the family-apartments. We should also forbid the introduction of plants into our parlours and drawing-rooms, in order to guard against those diseases that are supposed to originate in an excefs, or deficiency, either of azote or oxigene. To enter further into the medical history of those airs would in this place be thought improper. * It must be confefsed that sowing of Acorns, Beech-Mast, Ash-Keys, &c. in the Autumn, when those seeds fall spontaneously from the trees, appears by much the most natural method; but the destruction made by the field-mouse upon those seeds, both at the time of sowing and during the winter, has induced many gentlemen to prefer Spring- sowing to the Autumnal one. When the first is determined on, the acorns and other jeeds must be carefully preserved during the winter; and, in forming the magazines, care must be taken to keep the different sorts apart from each other. It is not customary to preserve the acorns, &c. in the manner recommended by Mr. Evelyn; but, as he always Ipeaks from experience, his method should not be rashly condemned.. OF FOREST-TREES. 25 4. But to pursue this to some farther advantage, as to what concerns the election of your seed, it is to be considered, that there is a vast difference in trees even of the same growth and bed, which I judge to proceed from the variety and quality of the seed: This, for instance, is evidently seen in the heart, procerity, and stature of timber ; and there- fore choose not your seeds always from the most fruitful trees, which are commonly the most aged and decayed; but from such as are found most solid and fair. Nor, for this reason, covet the largest acorn, 8cc. but (as husbandmen do their wheat) the most weighty, clean, and bright- This observation we deduce from fruit-trees, which we seldom find to bear so kindly and plentifully from a sound stock, smooth rind, and firm wood, as from a rough, lax, and untoward tree; which is rather prone to •spend itself in fruit (the ultimate effort, and final endeavour of its most delicate sap) than in solid and close substance to increase the timber. And this shall suffice, though some haply might here recommend to us a more accurate microscopical examen, to interpret their most secret schematisms, which were an over nicety for these great plantations. 5. As concerning the medicating and insuccation of seeds, or enforcing the earth by rich and generous composts, &c. for trees of these kinds, I am no great favourer of it; not only because the charge would much discourage the work, but for that we find it unnecefsary, and, for most of our forest-trees, noxious; since even where the ground is too fertile, they thrive not so well; and If a mould be not proper for one sort, it may be fit for another. Yet I would not, by this, hinder any from the trial, what advance such experiments will produce: In the mean time, for the simple imbibition of some seeds and kernels, when they prove extraor- dinary dry, as the season may fall out, it might not be amifs to macerate them in milk or water only, a little impregnated with cow-dung, &c. during the space of twenty-four hours, to give them a spirit to sprout and chet the sooner; especially if you have been retarded in your sowing without the former preparation: But concerning the mould, soiling, and preparations of the ground, I refer you to my " Treatise of Earth," if what you meet with in this do not abundantly encounter -all those difficulties. 6. Being thus provided with seeds of all kinds, I would advise to raise woods by sowing them apart in several places destined for their growth, where the mould being prepared (as I shall show hereafter) and so quali- Volume I.

As to the Air and Waten, they are certainly of almost as great import- ance to the life and prosperity of trees and vegetables; and therefore it is to be wished for and sought, (and they commonly follow, or indicate the nature of the soil, or the soil of them,) that they be neither too keen or sharp, too cold or hot, not infected with fogs and poisonous vapours, or exposed to sulphurous exhalations, or frigiverous winds, reverberating from hills and other ill-situate eminences, prefsing down the incumbent particles so tainted or conveyed through the inclosed vallies; but such as may gently enter and pervade the cenabs and vefsels, destined and ap- pointed for their reception, irrtromifsion, respiration, and pafsage, in almost continual motion: In a word, such as. is most agreeable to the life of man, duly qualified with their proper mixts, be it nitre, or any other vege- table matter, though we neither see, nor distinctly taste it; nay, so univer- sally pervading and necefsary, that all aquatics, how deeply soever submerged, could not subsist without this active element the ah. water.. The same qualification is, as we said, required' in Water, to which it is of so near alliance, and whose office it is not only to humectate, mollify,, and prepare both the seeds and roots of vegetables, to receive the nutrition, pabulum, and food, of which this of water as well as air are the proper vehicles, insinuating what they carry into -the numerous pores, and through the tubes, canals, and other emulgent pafsages and percola- tions to the several vefsels, where (as in a stomach) it is elaborated, concocted, and digested, for distribution through every part of the plant; and therefore had need be such as should feed, not starve, infect, or corrupt; which depends- upon the nature and quality of the mixed, with what other virtue, spirit, mineral, or other particles, accompanying the purest springs (to appearance) pafsing through the closest strainers. This therefore requires due examination, and sometimes exposure to the air and sun, and accordingly the crudity and other defects taken off and qualified: From all which rain-water that has had its natural circulation,, is greatly free, so it meets with no noxious vapours in the defcent, as it must do pafsing through clouds of smoak and soot, over and about great cities, and other volcanoes,, continually vomiting out their acrimonious, and sometimes pestiferous fervour, infecting the ambient air, as it OF FOREST-TREES. 27 perpetually does about London and for many miles adjacent, as I have chap. i. shown in my treatise entitled Fumifugium. -*~v~*- In the mean time whether water alone is the cause of the solid and bulky part, and consequently of the augmentation of trees and plants, or without any thing more to do with that element than as it serves to trans- port some other matter, is very ingeniously discufsed, and curiously in- quired into by Dr. "Woodward, in his History of the Earth, fortified with divers nice experiments too large to be here inserted '. The sum is, that 1 It is of the utmost consequence to determine what is the Food of Plants. Upon that question Philosophers have widely differed. From a number of experiments, accurately conducted, I am led to believe that all vegetables, from the hyfsop upon the wall, to the cedar of Lebanon, receive their principal nourishment from oily particles incorporated with water, by means of an alkaline salt or absorbent earth. Until oil is made miscible, it is unable to enter the radical vefsels of vegetables; and, on that account, Providence has bountifully supplied all natural soils with chalky or other absorbent particles. I say na- tural soils ; for those which have been afsisted by art are full of materials for that purpose; *uch as lime, marl, soap-ashes, and (he volatile alkaline salt of putrid dunghills. It may be asked, whence do natural soils receive their oily particles ? I answer, the air supplies them. During the summer months, the atmosphere is full of exhalations arising from the steam of dunghills, the perspiration of animals, and smoke. Every •shower brings down these putrescent and oleaginous particles for the nourishment of .plants. Of these particles, some fall into the sea, where they probably serve for the nourishment of fuci, and other submarine plants. They are, however, but seemingly lost, as the fish taken from the sea, and the weeds thrown upon the beach, restore them again .under a different form. Thus Providence, with the most consummate wisdom, keeps up -the necefsary rotation of things. .

The ingenious Mr. Tull, and others, contend that earth is the food of plants. If so, all •soils equally tilled would prove equally prolific. The increased fertility of a well-pulverised soil, induced him to imagine that the plough could so minutely divide the particles of . earth, as to fit them for entering into the roots of plants. An open soil, if not too light in its own nature, will always produce plentiful crops. It readily receives the air, rains, and dews into its bosom, and at the same time gives the roots of plants a free pafsage in quest of food. This is the true reason why land well tilled is so remarkably fruitful. — Water i^ thought, by some, to be the food of vegetables, when in reality it is only the vehicle of nourishment. Water is an heterogeneous fluid, and is no where to be found pure. It always contains a solution of animal or vegetable substances. These constitute the nourishment of plants, and the element in which they are minutely suspended, acts ^only as a vehicle, in guiding them through the fine velsels of the vegetable body. The -L-2 28 A DISCOURSE water, be it of rain or the river, (superior or inferior,) carries with it a certain superfine terrestrial matter, not destitute of vegetative particles, which gives body, substance, and all other requisites to the growth and perfection of the plant, with the aid of that due heat which gives life and motion to the vehicle's pafsage through all the parts of the vegetable, continually ascending, till (having sufficiently saturated them) it trans- hyacinth, and other bulbous roots, are known to perfect their flowers in pure water. — Hence superficial observers have drawn an argument in favour of water being the food of vegetables. But the truth is, the roots, stem, and flowers of such plants are nourished by the mucilaginous juices of the bulb, diluted by the surrounding water. This mucilage is just sufficient to perfect the flower — and no more. Such a bulb neither forms seeds, nor sends forth off-sets. At the end of the season, it appears weak, shrivelled, and exhausted, and is rendered unfit to produce flowers the succeeding year. A root of the same kind, that has been fed by the oily and mucilaginous juices of the earth, efsentially differs in every particular : it has a plump appearance, is full of mucilage — with off-sets upon its sides. All rich soils, in a state of nature, contain oil; and in those lands which have been under the plough for some years, it is found in proportion to the quantity of putrid dung that has been laid upon them, making an allowance for the crops they have sustained. To set this matter in a clearer light, let us attend to the effects of manures of an oily nature, and we shall soon be satisfied that oil, however modified, is one of the chief things concerned hi vegetation. Rape-dust, when laid upon land, is a speedy and certain manure, though an expensive one, and will generally answer best on a limestone land, or where the soil has been moderately limed. This species of manure is much esteemed by the farmer. It contains the food of plants ready prepared; but as it is not capable of loosening the soil by any fermentation, the lands upon which it is laid ought to be in excellent tilth. At present,, that useful article of hufbandry is much diminished in goodnefs, owing to the improved methods of extracting the oil from the rape; Heat and prefsure are employed in a double degree. Farmers that live in the neighbourhood of large towns use abundance of soot. It is an oily manure, but different from the former, containing alkaline salt in its own. nature, calculated as well for opening the soil, as for rendering the oily parts miscible with water. It is observed that pigeon's dung is a rich and hasty manure. These animals feed chiefly upon grains and oily seeds ; it must therefore be expected that their dung should contain a large proportion of oil. The dung of stable-kept horses is also a strong manure, and should not be used until it has undergone the putrid ferment, in order, to mix and afsimilale its oily, watery, and saline parts. Beans, oats, and hay, contain much oil. The dung of horses that are kept upon green herbage, is of a weaker kind, containing much lefs oil. Swine's dung is of a saponaceous and oily nature, and perhaps is the richest of the animal manures. When made into a compost and applied with judg- ment, it is excellent both for arable and grafs lands. The dung of stall-fed oxen, espe- cially if oil-cake make part of their food, is of a rich quality and greatly preferable to that of cows and oxen supported by grafs only. A farmer, when he purchases dung should attend to all the circumstances under which it is produced. One load of dung from a hunting stable where much corn is consumed, is worth two loads produced by hay and; OF FOREST-TREES. 29 pires the rest of the liquid at the summity and tops of the branches into the atmosphere, and leaving some of the lefs-refined matter in a viscid honey-dew, or other exsudations, (often perceived on the leaves and blofsoms,) anon descending and joining again with what they meet, repeat this course in perpetual circulation. Add to this, that from hence those regions and places, crowded with numerous and thick-standing forest- green provender. The dung of ruminant animals, as cows and sheep, is preferable to that of horses at grafs, owing to the quantity of animal juices mixed with their food in chewing. And here I beg leave to remark in general, that the fatter the animal, ceteris paribus, the richer the dung. Human ordure is full of oil and a volatile alkaline salt. By itself, it is too strong a manure for any land ; it should therefore be made into a compost before it is used. The dung of carniverous animals is plentifully stored with oil. Animals that feed upon seeds and grains come next, and after them follow those which subsist upon grafs only. To suit these different manures to their proper soils, requires the greatest judgment of the farmer, as what may be proper for one soil, may be highly detrimental to another. In order to strengthen my argument in favour of oil being the principal food of plants, I must beg leave to observe, that all vegetables, whose seeds are of an oily nature, are found to be remarkable impoverishers of the soil, as hemp, rape, and (lax ; for which reason, the best manures for lands worn out by these crops, are such as have a good deal of oil in their composition ; but then they must be laid on with lime, chalk, marl, or soap- ashes, so as to render the oily particles miscible with water. The book of nature may be displayed, to show that oily particles constitute the nourishment of plants in their embryo state ; and, by a fair inference, we may suppose that something of the same nature is con- tinued to them as they advance in growth. The oily seeds, as rape, hemp, line, and turnip, consist of two lobes, which, when spread upon the surface, form the seminal leaves. In them the whole oil of the seed is contained. The moisture of the atmosphere pene- trates the cuticle of the leaves, and, mixing with the oil, constitutes a kind of milk for the nourishment of the plant. The sweetnefs of this balmy fluid invites the fly, against which no sufficient remedy has, as yet, been discovered. The oleaginous liquor being consumed, the seminal leaves decay, having performed the office of a mother to her tender infant. To persons unacquainted with the analogy between plants and animals, this reflection will appear strange. Nothing, however, is more demonstrable. Most of the leguminous and farinaceous plants keep their placenta, or seminal leaves, within the earth ; in which situation they supply the tender germ with oily nutriment, until its roots are grown suf- ficiently strong to penetrate the soil. It is usual to talk of the salts of the earth ; but chymistry has not been able to discover any salts in land which has not been manured, though, it is said, that oil may. be obtained from every soil, the very sandy ones excepted. Marl, though a rich manure, has no salts. It is thought to contain a small portion of oleaginous matter, and an absorbent earth, of a nature similar to limestone, with a large quantity of clay intermixed. Lime mixed with clay comes nearest to the nature of marl of any factitious body that we know of, and may- 50 A DISCOURSE .book i. trees and woods, (which hinder the necefsary evolition of this superfluous s"*""v"^"/ moisture and intercourse of the air,) render those countries and places more subject to rain and mists, and consequently unwholesome, as is found in our American plantations, as formerly nearer us in Ireland ; both since so much improved by felling and clearing these spacious shades, and letting in the air and sun, and making the earth fit for tillage and be used as such, where it can be had without much expence. By increasing the quantity -of clay, it will make an excellent compost for a light sandy soil; but to make the ground fertile, woollen rags, rotten dung, or any -oily manure, should be incorporated with it some time before it is laid on. It is the opinion of some, that lime enriches the land it is laid upon, by means of supplying a salt fit for the nourishment of plants ; but by all the expe- riments that have been made upon lime, it is found to contain no kind of salt. Its opera- tion therefore should be. considered in a different light ; by the fermentation that it induces the earth is opened and divided, and, by its absorbent and alkaline quality, it unites the -oily and watery parts of the soil. It also seems to have the property of collecting some- thing from the air, but with which we are not yet sufficiently acquainted. From viewing lime in the light of afsimilating oil and water, it is probable that it tends to rob the soil of .its oily particles,, and in time will render it barren, unlefs we take care to support it with rotten dung, or other manures of an oily nature. As light sandy soils contain but a small portion of oleaginous particles, we should be extremely cautious not to overdo them with lime, unlefs we can at the same time afsist them liberally with rotten dung, woollen rags, shavings of horn, and other manures of an animal kind. Its great excellence, however, upon a sandy soil, is by mechanically binding the loose particles, and thereby preventing the liquid parts of the manure from escaping out of the reach of the radical fibres of the plants. Upon clay the effect of lime is different; for by means of the gentle fermentation that it produces, the unsubdued soil is opened and divided : the manures laid on readily come into contact with every part of it; and the fibres of the plants have full liberty to spread them selves. It is generally said that lime answers better upon sand than clay. — This observation will undoubtedly hold good as. long as the farmer continues to lime his clay lands- in a scanty manner. Let him double the quantity, and he will then be con- vinced that lime is better for clay than sand. It may be justly answered, that the profits will not admit of the expence. I agree. But then it must be understood that it is the application, and not the nature of the lime, that should be -called-in question. Clay, well limed, will, after a time, fall in water, and ferment with, acids. Its very nature is changed Under such. agreeable circumstances, the .air, rains, and dews are freely admitted, and the soil is enabled to retain the nourishment that each of them brings. In consequence of a fermentation raised in the soil, the fixed air is set at liberty, and in that state of activity it becomes an useful instrument in dividing the tenaceous clay. However, let the farmer who uses much lime for his clay lands, be instructed to manure them well, otherwise the -soil will become too hard to permit the roots of the plants to spread themselves in search of food. It is the nature of lime to attract oils, and tlifsolve vegetable bodies. Upon these .^principles .we may account for the wonderful effects of lime in the improvement of black OF FOREST-TREES. S* pasture, that those gloomy tracts are now become healthy and habitable. It is not to be imagined how many noble seats and dwellings in this na- tion of ours (to all appearance well situated) are for all that unhealthful, by reason of some grove or hedge -rows of antiquated dotard trees (nay, sometimes a single tuft only, especially the falling autumnal leaves neg- lected to be taken away) filling the air with musty and noxious exhala- moor-land. Moor-earth consists of difsolved, and half-difsolved vegetable substances. It is full of oil. Lime difsolves the one and afsimilates the other. Such lands, not originally worth fourpence per acre, may be made by paring, burning, and liming, to produce plen- tiful crops of turnips, which may be followed by oats, rye, barley, or grals-seeds, according to the inclination of the owner. These observations, however, are rather foreign to the present argument, to which I shall now return. To the universal principle, oil, we must add another of great efficacy, though very little understood ; I mean the nitrous acid of the air. That the air does contain the rudiments of nitre, is demonstrable from the manner of making salt-petre in the different parts of the world. The air contains no such salt as perfect nitre ; it is a factitious salt, and is made by the nitrous acid falling upon a proper matrix. The makers of nitre form that matrix of the rubbish of old houses, fat putrescent earth, and any fixed alkaline salt. The universal acid, as it is called, is attracted by these materials, and forms true nitre, which is rendered pure by means of crystallization, and in that form it is brought to us. In very hot coun- tries the natural earth forms a matrix for nitre, which makes the operation very short. It is observed that nitre is most plentifully formed in winter, when the wind is northerly: hence we may understand the true reason why farmers and nurserymen lay up their lands in high ridges during, the winter months. The good effects of that operation are in general attributed to the mechanical action of the frost upon the ground. Light soils, as well as tough ones, may be exposed in high ridges, but with some limitation, in order to imitate the mud walls in Germany, which are found, by experience, to collect considerable quan- tities of nitre during the winter. After saying so much in praise of nitre, it will be ex- pected that I should produce some proofs of ils efficacy, when used as manure. I- must confefs that experiments do not give us any such proofs. Perhaps too large a quantity has been used j or rather, it could not be restored to the earth with its particles so minutely divided, as when it remained united with the soil, by means of the chymistry of Nature. 1 shall therefore consider this nitrous acid, or, as philosophers call it; the acidum vagum, in the light of a vivifying principle, with whose operation we are not yet fully acquainted A curious observer will remark, that there subsists a strong analogy between plants and animals. Oil and water seem to make up the nourishment of both: Earth enters very little into the composition of either. It is known that animals take in a great many earthy particles at the mouth, but they are soon discharged by urine and stool. Vegetables take in the smallest portion imaginable of earth j and the reason is, thev have no way to dis- charge it. It is highly probable, that the radical fibres of plants take up their nourishment. from the earth in the same manner that the lacteal vefsels absorb the nutriment from the intestines ; and as the oily and watery parts of our food are perfect! <• united into a milk.*- S2 A DISCOURSE tions, which being ventilated by glades cut through them, For pafsage of the stagnant vapours, have been cured of this -evil, and recovered their reputation. But to return to where we left-: Water in this action, imbibed with such matter, applicable to every species of plants and vegetables, does liquor, by means of the spittle, pancreatic juice, and bile, before they enter the lacteals, we have all the reason imaginable to keep up the analogy, and suppose that the oleaginous and watery parts of the soil are also incorporated, previous to their being taken up by the absorbing vefsels of the plant. To form a perfect judgment of this, we must reflect that every soil, in a state of nature, has in itself a quantity of absorbent earth, sufficient to in- corporate its inherent oil and water ; but when we load it with fat manures, it becomes efsentially necefsary to bestow upon it, at the same time, something to afsimilate the parts. Lime, soap-ashes, kelp, marl, and all the alkaline substances, perform that office. In order to render this operation visible to the senses : difsolve one drachm of Rufsia pot-ash in two ounces of water ; then add two spoonfuls of oil. Shake the mixture, and it will instantly become an uniform mafs of a whitish colour, adapted, as I conceive, to all the purposes of vegetation. This easy and familiar experiment is a just representation of what happens after the operation of Bum-baking, and consequently may be considered as a confirmation of the hypothesis advanced. Let us attend to the procefs. The sward "being reduced to ashes, a fixed alkaline salt is produced. The moisture of the atmosphere soon reduces that salt into a fluid state, which, mixing with the soil, brings about an union of the oily and watery parts, in the manner demonstrated by the experiment. When the under stratum consists of a rich vegetable mould, the effects of Bum-baking will be lasting. But when the soil happens to be thin and poor, the first crop frequently suffers before it arrives at maturity. The farmer, therefore, who is at the expence of paring and burning a thin soil, should bestow upon it a portion of rotten dung, or shambles manure, before the ashes are spread, in order to supply the deficiency of oily particles. In consequence of this prudent management, -the crop will be supported during its growth, and the land will be preserved in health and vigour. Hitherto I have considered plants as nourished by theirroots. I shallnow take a view of them as nourished by their leaves. An attention to this part of the vegetable system is efsentially necefsary. Vegetables that have a succulent leaf such as vetches, pease, beans, and buck-wheat, draw a great part of their nourish- ment fromthe air, and on that account impoverish the soil lefs than wheat, oats, barley, or r\e, the leaves of which are of a firmer texture. In this mariner the vegetable creation .renders- the air pure, \>y afsimilating to itself those putrescent particles, which, if not re- moved, would render the atmosphere unfit for animal respiration. Rape and hemp are oil-bearing plants, and, consequently, impoverishes of the soil ; but the former lefs so than the latter, owing to the greater succulency of its leaf. The leaves of all kinds of grain are succulent for a time, during which period the plants take little from the earth ; but as soon as the ear begins to be formed, they lose their softnefs, and diminish in their attractive power. The .radical fibres are then more vigorously cmplojed in extracting the oily par- ticles of the earth, foi the nourishment of the seed. OF POREST-TREES, S3 not, as we affirmed, operate to the full extent and perfection of what it gives and contributes of necefsary and constituent matter, without the soil and temper of the climate co-operate, which otherwise retards Vegetables being fixed to a place, have few offices to perform. An increase of body and maturation of their seed, seems all that is required of them. For these purposes, Providence has wisely bestowed upon them organs of a wonderful mechanism. The anatomical investigation of these organs, is the only rational method of arriving at any certainty concerning the laws of the vegetable ceconomy. Upon this subject Dr. Hales judiciously observes, " That as the growth and preservation of vegetable life is promoted " and maintained, as in animals, by the very plentiful and regular motion of their fluids, " which are the vehicles ordained by Nature to carry nutriment to every part, it is ** therefore reasonable to hope, that in them also, by the same method of inquiry, '• considerable discoveries may in time be made ; there being, in many respects, a great " analogy between plants and animals." The seed of a plant, after it has dropt from the ovarium, may be considered as an impregnated ovum, within which the embryo plant is securely lodged. In a few days after it has been committed to the earth, we may discern the rudiments of the future plant. Every part appears to exist in miniature. The nutritive juices of the soil insinuate themselves between the original particles of the plant, and bring about an extension of its parts. This is what is called the Growth of the vegetable body. With regard to this increase by addition and extension, there seems to be a great analogy between the animal and vegetable kingdoms. I have already endeavoured to prove, that oily particles constitute the chief nourishment of plants and animals; and as I apprehend that much depends upon a proper investigation of the subject, I shall occasionally introduce come other proofs in support of my opinion. Every one knows that animals, instead of being strengthened, are enfeebled by a supply of improper nourishment. It is the same thing with regard to vegetables; but with this difference, that animals refuse whatever is improper, while vegetables, from their pafsive nature, must be content with what we give them. The impregnated ovum of every animal, after it has pafsed down the Fallopian tube, and fixed itself to the bottom, or side, of the uterus, is found to contain the tender embryo within two membranes called Chorion and Amnion. In this situation the embryo could not long subsist without a supply of nourishment. Nature has therefore bestowed upon it a placenta and umbilical chord, through which the blood and juices of the mother are transmitted, for its preservation and increase. Seeds are disposed by Providence nearly in the same manner. They have two coverings, answering to the Chorion and Amnion, and two lobes which perform the office of the placenta. These lobes constitute the body of the seed, and, in the farinaceous kinds, they are the flour of the grain. Innumerable small vefsels run through the substance of the lobes, which, uniting as they approach the seminal plant, form a small chord to be inserted into the body of the germ. Through it the nutriment supplied by the placenta, or lobes, is conveyed for the preservation and increase of the embryo plant. In order that I may bo Volume I.

This we find, that the hot and warmer regions clearly understood, it will be necefsary to observe, that the lobes of most farinaceous grains are fixed in the earth: They are therefore improperly termed seminal leaves, being rather the placenta, or cotyledons of the plant. On the contrary, vegetables that have an oily seed, as rape, hemp, line, and turnip, carry their lobes upwards, and spread them upon the surface, in the form of broad leaves. These, though they perform the office of a placenta, are properly seminal leaves; and to this distinction I shall adhere.

As soon as the coronal, or spring root, puts out, the pipe of communication throws off its covering, and appears naked, as in Fig. 4. b. — Regarding these two kinds of roots, the osconomy of Nature is wonderful. The seminal root, lying deep, nourishes the tender plant during the severity of winter ; but when the spring comes on, and it is necefsary that the plant should advance in size, the coronal root then shoots forth and spreads its fibres just within the surface, where the land is always the richest. When the seed happens to be buried very deep, Nature lengthens the pipe of com- munication, and on no account will form the crown, from whence the spring roots are sent forth, till the surface is obtained : Fig. 4. 1 believe I do not err when I call this vegetable instinct. To illustrate the subject of vegetation, let us take a view of what happens to a bean after it has been committed to the earth. In a few days, sooner or later, according to the temperature of the weather and disposition of the soil, the external coverings open at one end, and disclose to the naked eye part of the placenta, or body of the grain. This substance consists of two lobes, between which the seminal plant is securely lodged. Soon after the opening of the membranes, a sharp-pointed body appears ■ This is the root. By a kind of principle, which seems to carry with it some appearance of instinct, it seeks a pafsage downwards, and fixes itself into the soil. At this period the root is a smooth and polished body, and perhaps has but little power to absorb any thing from the earth, for the nutriment of the germ. The two lobes now begin to separate and the germ, with its leaves, may plainly be discovered. As the germ increases in size, the lobes are further separated, and the tender leaves being closely joined, push themselves forward in the form of a wedge. These leaves take a contrary direction to the root- Influenced by the same miraculous instinct, if I may be allowed the exprefsion, they seek a pafsage upward, whjch having obtained, they lay aside their wedge-like form, and Hu*e 34 \,YV r 'I, /■/,,■/„,/ /,™"/','^7y, V. r '//,',„/,,'.

The radiele, every hour increasing in size and vigour, pushes itself deeper into the earth, from which it now draws some nutritive particles. At the same time the leaves of the germ, being of a succulent nature, afsist the plant, by attracting from the atmosphere such particles as their tender vefsels are fit to convey. These particles, however, are of a watery kind, and have not in their own nature a sufficiency of nutriment for the increasing plant. Vegetables and animals, during their tender states, require a large share of balmy nourishment. As soon as an animal is brought into life, the milk of its mother is supplied in a liberal stream, while the tender germ seems only to have the crude and watery juices of the earth for its support. In that, however, we are deceived. The Author of Nature, with equal eye, watches over the infancy of all his works. The animal enjoys the milky humour of its parent. The vegetable lives upon a similar fluid, though differently supplied. For its use the farinaceous lobes are melted down into a milky juice, whkli, as long as it lasts, is conveyed to the tender plant by means of innumerable 6mall vefsels, which are spread through the substance of the lobes. Thefe vefsels enter the body of the germ, and perform the office of an umbilical chord. Without this supply of balmy liquor, the plant must inevitably have perished ; its root being then too small to absorb a sufficiency of food, and its body too weak to afsimilate it into nourishment. How beautiful is the resemblance between this and the imagery of Lucretius ! Hinc ubi quxque loci regio opportuna dabatur, Crescebant uteri terra radicibus apti: Quos ubi tempore maturo patefecerat aelas Infantum fugiens humorem, aurasque petifsens, Convertebat ibi natura foramina terra, Et succum venis cogebat fundere apertis Consimilem lactis, sicut nunc foemina quaque Cum peperit, dulci repletur lacte, quod omnis Impetus in mammas convertitur ille alimenti. Lib. v. 1. 807. Turnips, and all the tribe of Brafsicas, in opposition to most of thelegumenous and farina- ceous plants, spread their seminal leaves upon the surface. These leaves contain all the ■oil of the seed, which, when diluted by the moisture of the atmosphere, forms an emulsion of the most nourishing quality. How similar is this juice to the milk of animals! On account of its sweetnefs, the seminal leaves are greedily devoured by the fly. This demonstrably proves that oil constitutes the nourishment of plants in their tender state; and, by a fair inference, we may suppose that it also nourishes them as they advance M2 S6 A DISCOURSE book i. but a shrubby dwarf in the other; deficient of that active spirit, which ^""v^*-7 elevates and spreads its prolific matter and continual supplies without check, and is the cause of the leaves deserting the branches, whilst those trees and plants of the more benign climate are clad in perennial verdure; and those herbaceous plants, which with us in the hottest seasons hardly perfect their seeds before winter, require to be near their genial beds and nurse, and sometimes the artificial heat of the hot-bed. Lastly, to all this I would add that other cheerful vehicle, Light, which the gloomy and torpent North is so many months deprived of, the too long seclusion whereof is injurious to our exotics kept in the conserva- tories; since however tempered with heat, and duly refreshed, they in growth. A grain of wheat, as soon as the germ has made its appearance, shows the milky liquor to the naked eye. As the plant increases in size, the balmy juice diminishes, till at last it is quite exhausted. The umbilical vefsels then dry iip, and the external covering of the grain appears connected to the root in the form of a shrivelled bag/ See Fig. 4. c. — Here is no mortality : From the moment that the seed is lodged in its parent earth, the vegetative soul begins its operations, and, in one continued miracle, proves the wisdom and bounty of an Almighty Providence. It is worthy of observation, that farinaceous vegetables and oviparous animals are nourished, in their tender states, nearly in the same manner. We have already seen that the embryo plant is supported by the farina melted down into a milky liquor, and conveyed into its body by means of an umbilical chord, at a time when the radicle was unable to supply a sufficiency of nutriment. In like manner an oviparous animal, from the time it is brought into light, seems to receive all its nourishment from without. This, however, is only an appearance: The yolk of the egg, remaining entire during incubation, is received into the body of the animal, and in a manner similar to the pafsage of the milky juice of the vegetable, is slowly conveyed into the vefsels of the tender chick. Thus a sweet nourishment is prepared at a time when neither the industry of the animal, nor the attention of its mother, could have procured a sufficient supply. How beautiful are the general laws of Providence! The more we explore them, the more we have cause for wonder and astonishment! Every thing is wisely disposed; nothing is fortuitous; all is order, regularity, and wisdom : Was every faultering tongue of man, Almighty Father! silent in thy praise, Thy works themselves would raise a general voicej Ev'n in the depths of solitary woods, By human loot untrod ; proclaim thy power, And to the quire celestial Thee resound, Th' eternal caufe, support, and end of all.

In thick, forests, the young trees always lean to the side where the light penetrates. The new shoots of an espalier detach themselves from the wall which robs them of the air the sun and the light. It is in quest of the same excellent gifts of Nature, that the lateral branches of- trees, abandoning the direction of the stem, spread and extend themselves in a direction parallel to the soil, even when planted on a declivity. Trunks are not, however the only parts of plants which direct their course towards the air and the light of the sun There are flowers, which, quitting their perpendicular direction, present their surface directly to that luminous body, and follow it in its diurnal course. This sort of motion has been called by some writers, nutation ; and the plants which are subject to it have been termed Heliotrojia ; that is, turning with the sun. The story of the Sun-flower in Ovid's Metamorphoses, is confirmed by daily observation. Thomson beautifully de- scribes its affection: But one, the lofty follower of the sun; Sad when he sets, shuts up her yellow leaves, Drooping all night ; and, when he warm returns, Points her enamour'd bosom to his ray. Most of the discous flowers, by some power unknown to us, follow the sun in his course.

This being a cheap and laudable work, of so much pleasure in the execution, and so certain a profit in the event, when once well done, (for, as I affirmed, a very small plantarium, or nursery, will, in a few years, stock a vast extent of ground,) has made me sometimes in admiration at the universal negligence; as well as raised my admiration, that seeds and plants of such different kinds, should, like so many tender babes and infants, suck and thrive at the same breasts; though there are some indeed will not so well prosper in company, requiring peculiar juices: But this nicenefs is more conspicuous in flowers and the herbaceous offspring, than in foresters, which require only diligent weeding and frequent cleansing, till they are able to shift for themselves ; and as their vefsels enlarge and introsume more copious nourishment, they often starve their neighbours. 2. Having therefore made choice of such seeds as you would sow, by taking and gathering them in their just season, that is, when dropping ripe, and as has been said, from fair thriving trees, and found out some .fit piece of ground, well fenced, respecting the south-east rather than OF FOREST-TREES. 39 the full south, and well protected from the north and west, let it be chap. ii. broken up the winter before you sow, to mellow it; especially if it be a v,^~y"^^ clay, and then the furrow should be made deeper, or so at least as you would prepare it for wheat: Or you may trench it with the spade, by which means it will the easier be cleansed of whatsoever may obstruct the putting forth, and insinuating of the tender roots.

He that for wood his field would sow, Must clear it of the shrubs that grow; Cut brambles up, and the fern mow. Ha'ing given it a second stirring, immediately before you sow, cast and dispose it into rills, or small narrow trenches, of four or five inches deep, and in even lines, at two feet interval, for the more commodious runcation, hawing, and drefsing the trees: Into these furrows, about the new or increasing moon, throw your Oak, Beech, Ash, Nuts, all the glandiferous seeds, mast and key-bearing kinds, so as they lie not too thick, and then cover them very well with a rake, or fine-toothed harrow, as they do for pease : Or, to be more accurate, you may set them as they do beans, especially the Nuts and Acorns, and every species by themselves, for the Roboraria, Glandaria, Ulmaria, &c. which is the better way n : This is to be done at the latter end" of October, for the autumnal sowing, and in the lighter ground about February, for the n The most natural, direct, and general way of raising trees and plants is from seeds. In order to this, proper soils must be prepared for them, as suitable as pofsible to their respective natures ; and when the ground is ready, and well furnished with the embryo plants, it is properly and significantly called the Seminary. Its situation should be as near the nursery as pofsible; and as it is of the utmost consequence to preserve the young plants from being cropped by hares in the winter, the ground should be fenced round with pales of a sufficient height In the beginning of winter let the land be trenched about two spits deep, working the sward to the bottom; and during the spring, the surface should be carefully kept clear from weeds. About Midsummer, unlefs the soil be very rich, let some rotten dung be spread over the surface, after which it should again be trenched. By this second operation the rotten swarth will be brought to the top, and the soil will put on a mellow appearance. From Midsummer to September, the ground should be kept clear of weeds ; and just before the seeds are committed to it, it should again be 40 A DISCOURSE book I. vernal. For other seminations in general, some divide the spring in *^"V*«^ three parts, the beginning, middle, and end; and the like of the autumn, both for sowing and planting, and accordingly prepare for the work such nursery furniture as seems most agreeable to the season ; Proinde nemus sparsa cures de glande parandum: Sed tamen ante tuo mandes quam semina campo, Ipse tibi duro robustus voraere fofsor Omne solum subigat late, explanetque subactum.

Then see your hopeful grove with Acorns sown; But e'er your seed into the field be thrown, With crooked plough first let the lusty swain Break up, and stubborn clods with harrow plane : Then, when the stem appears, to make it bare, And lighten -the hard earth with hough, prepare : ] Hough in the spring, nor frequent culture fail, Lest noxious weeds o'er the young wood prevail. To barren ground with toil large manure add ; .Good husbandry will force a foil that's bad.^ Note, that six bushels of Acorns will sow or plant an acre at one foot's distance: And if you mingle amongst the Acorns the seeds of trenched which will effectually produce an uniform mixture of all the parts. This being clone, let the ground be levelled, and the'beds laid out for the different purposes, reserving proper portions for the reception of such seeds as must be sown in spring. Avery judicious planter has recommended to me the following method of making a Seminary. Trench the ground in November eighteen inches deep, if the soil will admit of it- but where the staple is too thin, one foot will be sufficient, in which case the sward must be pared off very thin, and laid in the bottom of the trench. The following year let this land be cultivated with a crop of cabbages, turnips, or rape, which must be eat off by sheep. After this a common digging will be sufficient, previous to its being formed into beds for the reception of the seeds. It will be necefsary to remark upon this mode of preparation, that the urine of sheep is considered as one of -the most cherishing manures for all plants raised in a Seminary. OF FOREST-TREES. 41 Genista Spinosa, or Furze, they will come up without any damage, and for a while prove a sufficient fence, and will be killed by the shade of the young Oaklings, before they become able to do them any prejudice. One rule I must not omit, that you cast no seeds into the earth whilst it either actually rains, or that it be over sobbed, till moderately dry. The Seminary being now ready, it follows that the planter should be instructed in the manner of sowing and raising the seeds of Forest-trees; and as Bradley, Miller, Hanbury, Weston, andMawe, have published useful directions upon this 'head, I flatter myself that I shall be thought right in transcribing their authorities for the manner of raising the following trees from seed. The Oak, the Pride and Glory of the Forest, is a native of this country, and suits itself to all sorts of soils. It is of slow growth; but its cultivation is of the utmost consequence to this nation. In order to raise this tree, let the acorns be procured from straight thriving trees, when they are full ripe and begin to fall. In February or March, (or in October, if the autumnal sowing be more agreeable,) prepare the beds four feet wide; rake the earth out into the alleys two inches deep,- and draw lines acrofs the bed at four inches asunder with a sharp-pointed stick; on these lines lay the acorns at about tw» inches distance from each other; when the bed is finished, prefs the seeds gently dowa ■with the back of the spade to keep them in their places, then spread the earth over them two inches thick, and rake the beds even ; by their being planted in rows four inches asunder, a two-inch hoe can pafs betwixt the rows without hurting the plants, by which the weeds are more easily destroyed, and the stirring the earth so much will cause the plants to grow the more, which advantage is lost if they are sown broadcast. It will be necefsary to place some traps in the alleys to catch the mice, particularly after autumnal sowing; the crows are also very fond of acorns; therefore it will be proper to guard against these enemies, or all your labour will be lost. For two years the plants may remain in the seed-bed, with only the care of weeding them constantly in summer, and •spreading a little fresh earth and ashes among them against the winter. They must then be "transplanted, in March or October, either where they are to remain, or else into the nursery? if into the nursery, it must be in rows two feet and a half asunder, and each plant at eighteen inches distance, where they must be constantly hoed, and the ground dug between them before winter, till they are planted out for timber. ELM. The Wych Elm is the only one that ripens its seeds well in (his country. The sce^ must be gathered the beginning of June, laid in a dry place for a few days, and then it will be fit to sow. After having formed the beds four feet wide, rake out the earth, about two inches deep, and sift it into the beds again, except leaving about half an inch of it to cover the seeds ; rake it level again4 and flat it a little with the back of the spade, J 'oil', me /. N 42 A DISCOURSE To this might something be expected concerning the watering of our Seminaries and new plantations ; which indeed require some useful directions, especially in that you do by hand. Pour it not with too great a stream on the stem of the plant, which washes and drives away the then sow the seeds, and sift the remaining earth over them. When you have sown the seeds, the beds must be hooped, and covered with mats to screen them from the sun ; but when it rains,, take them off; and if it be very dry weather, the beds must be frequently and gently watered. In about a month, many of the young plants will appear; towards September the mats may be taken away, but before winter the beds must be well weeded, and a quarter of an inch of ashes sifted over them. In spring the rest will appear, and during the summer they must be constantly weeded, frequently watered in dry weather, and have some earth sifted over them. The February following they must. be taken out of the seed-bed and planted in rows three feet asunder, and each plant at eight-en inches distance, where they are to remain with the usual care of digging between the rows, and hoeing the weeds in summer.. Gather a sufficient quantity of mast, about the middle of September, when it begins to fall; spread it upon a mat, in an airy place, for six days, to dry; and after that you may either proceed to sowing it immediately, or you may put it up in bags, in order to sow it nearer the spring; which method I would rather advise, as it will keep very well, and there will be lefs danger of having it destroyed by mice or other vermine, by which kinds of animals these seeds are greatly relished. The ground being ready for the seeds, line your beds out four feet wide, with alleys a foot and a half or two feet broad, for this is the properest width for raising the seeds of all sorts of forest-trees; let theearthbe raked out of each bed, one inch deep; and, after having levelled the bottom, and gently tapped it down with the spade, sow the seeds all over it, even and- regular; then tap them down with the back of the fpadeT and cover them over with mould an inch deep. In the spring of the year, many of the plants will make their appearance, whilst others will not come up till the following spring. After they have been two years in the seminary, they must be planted, in the nursery way, on some double-dug ground. The rows should be two feet and a half asunder, and the plants at eighteen inches distance in the rows. The rows ought to be kept clean of weeds in the summer, and dug between every winter. Here tfiey may remain till they are to be planted out for continuance. Procure the keys from healthy young thriving trees in October or November; rake some of the earth off into the alleys, to lower the bed about an inch ; sow the keys moderately thick then throw the earth back again lightly with a spade, or else sift it over them, an inch thick, and rake it level. In spring, with a vefy small light iron rake, (the teeth about an inch asunder,) rake off the mol's, pull up the weeds,, and again sift a. little earth uver the beds. They will want no other care the first year, except weeding. The OF FOREST-TREES. 45 mould from the roots and fibres; but at such distance as it may percolate chap, ii, into the earth, and carry its virtue to them, with a shallow excavation, ^■«^"y""*»-/ or circular basin, about the stalk; and which may be defended from being too suddenly exhausted and drunk up by the sun, and taken away second spring, in the first open weather in February, rake oft" very gently the earth as before, sift fresh over them, . about half an inch thick, and in March and April the young plants will appear in plenty. During the summer they must be constantly weeded, and in very dry weather, now and then watered ; in October weed them again, and sift some coal-ashes half an inch thick over them ; but if the heavy rains in the summer have laid the roots bare, it will be necefsary to sift a little earth amongst them first. No persons, unlefs they have practised this method of sifting earth and ashes over their seedling plants before winter, can conceive the advantage they receive from it; it strengthens the stems, prevents mofs from growing amongst them, and secures them from being turned out of the ground by the frost. The next spring prepare some beds six feet wide, with a path of two feet betwixt each ; plant all of a size in each bed, at one foot square, first shortening the tap-roots, and also the side ones ; in this bed they must remain for two years, hoeing the ground when any weeds appear, and against winter sprinkling a few ashes amongst them. After standing at this distance for two years, they will want removing; they mast then be planted out into your nursery, in rows three feet asunder, and each plant at one foot distance, where they are to remain till they are wanted for planting out for good; but observe to keep the weeds constantly down when small, for then a labourer with a Dutch hoe can clean near half an acre in a day, and your trees will thrive amazingly by such a practice. As the Ash keys do not make their appearance till the second spring, some judicious persons recommend them to be bedded in dry mould, and treated in the manner of haws. This method has many apparent advantages. In general the keys are sown too thick, which makes the plants come up tall and weak; a practice much to be condemned. In the winter let a sufficient quantity of cones be procured, and kept till the spring of the year. Just before sowing, let them be opened or torn into four quarters by a knife, the point of which must be thrust exactly down the centre, so that the seeds in their respective places may not be damaged. Formerly, great pains were bestowed in getting at the seeds, by cutting oft' the scales of the cones singly, and letting the seeds drop. This occasioned great expence to those who wanted a quantity of seeds ; so that it is now wholly laid aside, for the more easy method of opening them with knives, and then threshing them. A certain price is generally allowed per thousand to the poor for opening them. When a sufficient quantity is opened, they should be threshed in a room, which will divide the scales, and dislodge the seeds, without injuring many of them. Three thousand cones will generally produce about a pound of good seed. The cones being sufficiently broken, and the seeds threshed out, they should be winnowed or sieved, to have clear seeds; after which they will be ready for sowing in April. Let the seminary N2 44 A DISCOURSE book i. before it grow mouldy. The tender stems and branches should yet be ^-""-v*"*-' more gently refreshed, lest the too intense rays of the sun darting on them, cause them to wither; as we see in our fibrous flower-roots newly set. In the mean time, for the more ample young plantations of forest consist of a spot of fine light earth, and let the seeds be sown in beds a quarter of an inch- deep. After the plants have made their appearance, they should be gently refreshed with, water in dry weather, and carefully kept clean of weeds during the whole summer. By the autumn they will not have shot more than an inch or two; and in spring they should be pricked out in beds about three inches asunder. The second spring they must be taken out of these beds with care, and planted in the nursery, in rows three feet asunder, and the plants eighteen inches from each other; and here they may remain until they are fit to plant out for good, which will be about the second or third year after. When they grow well in the nursery, I would advise them to. be planted out where they are to continue, after having got two years strength, for these trees always thrive best that are removed small from the nursery, if they are only of a sufficient size not to be injured by the weeds. For an improved method, of. raising the Larch, consult its history in the Chapter on Pines. CHE3NUT. Before you attempt planting any Chesnuts, whether Foreign or English,, put them into a» tub of water, and let those that swim be thrown away. The middle of February draw four drills along each bed, at a foot distance and five, inches deep; in these drills place the- nuts at about four inches asunder, and cover them well. When the plants appear, weed, them very carefully, and if you make use of an hoe, it must be done with great care, for fear of hurting the tender bark ; but if any weeds break off within the ground, a carpenter's chifsel, about an inch broad, will be of great use in getting the roots ur> without damaging the plants. In the seminary they must stand two years, be well weeded, and earthed up before winter, and then some ashes spread amongst them. In February they will want transplanting intothe nursery (the ground being, first double dug) in rows, three feet asunder, and each plant at eighteen inches distance; after they have remained there another year, cut them down to the ground, by which they will shoot very strongly with handsome straight stems, and overtake those that have not undergone the same operation. Here they may remain four or five years, keeping them clean from weeds,, and digging betweea the rows. WALNUT. Having marked the trees that produce the finest nuts, either for thinnefs of shell or goodnefs of taste, we must proceed to gather them when they begin to fall. But as collecting them by the hand would be tedious, they may be beat down by long poles prepared for that purpose. Having procured the quantity wanted, let them be preserved,. with their husks on, in sand, till the beginning of February, which is the time for planting OF FOREST-TREES. 45 and other trees, I should think, the hydraulic engine called the Quench-fire, (described in the Philosophical Transactions, number 128,) might be made very useful, if rightly managed, and not too violently pointed against any single trees, but so exalted and directed, as the stream being them. This is to be done in the following manner: Let drills be made aerofs the seminary,. at one foot asunder, and about two inches and. a half deep, and let the nuts be put into them at the distance of about four inches. In spring the young plants will come up. In this situation they should continue for two years, being constantly kept clear of weeds ; when they will be of a proper size to plant oat in the nursery. The ground should be prepared, as has been always directed, by double digging; and the trees, having their tap-roots shortened, should be planted therein, in rows two feet and a half asunder, and at the distance of a foot and a half in the rows. Here they may remain, with the same culture as has been all along directed for the management of timber-trees, till they are of a proper size for planting out for good. If they are designed for standards to be planted in fields, &c. before they are taken out of the nursery they should be above the reach of cattle, which would otherwise wantonly break their leading shoots, though they do not care to eat them, on account of their extraordinary bitternefs. They ought likewise to- be removed with the greatest caution, and the knife should be very sparingly applied to the roots. They must also be planted as soon as pofsible after taking up; and this work should be always done soon after the fall of the leaf, in the manner that will be directed for planting out standard timber-trees. If these trees are intended to form a wood, for which purpose they answer extremely well, I would advise to take them out of the nursery when they are about three or four feet high, and to plant them about three yards asunder; and, after their heads begin to touch, they should be thinned. By this means, these large and branching trees will be drawn up, with beautiful stems, to a great height. At the last thinning of the trees, the standards should be left at about thirty feet distance: But if the owner expects to reap the benefit of the fruit, the distance ought to be seven or eight feet more. Procure the seeds from the red-twigged Lime, by beating them down with a pole in October; and spread them in a dry place for a few days before you sow them: Prepare your beds four feet wide, and rake the earth out about an inch deep ; level the bed, and then sow the seeds about an inch asunder, prefsing them down gently with the back of the spade, and covering them. In spring they will appear, and must be constantly weeded, and watered a little in very dry weather ; before winter, sift some ashes over them to>. destroy the mofs. The plants must remain in the seed-bed two years, and then (hey will be fit to plant out into the nursery in rows two feet and a half asunder, and each tree at eighteen inches distance; but before they are planted, shorten the roots a little, and cut off any side-branches. In this place they may remain for several years, (for they will bear removing at any size,) with hoeing the weeds down in summer, and digging between, them every year; but as you want them, it is better to take away every other tree, which, by giving more air, will increase the growth of those that remain. 46 A DISCOURSE book I, spread, the water might fall on the ground like drops of rain; which I s'— ■""v"**''' should much prefer before the barrels and tumbral way. Rain, river, or pond-waters, reserved in tubs or cisterns, simple or enriched, and abroad in the sun, should be frequently stirred, and kept from stagnation. HOES E-CH ES NU T. Tut the nuts in a tub of water, and throw away all that swim ; plant them in the same manner as the other Chesnuts, except that they are better put in the ground in October; for if they are kept till the spring many will miscarry. In spring they will appear, and when one year old they must be taken up, the tap-roots shortened, and then planted in the nursery, in rows three feet asunder, and each plant at eighteen inches distance: but there is this difference from the other Chesnuts, that, these make their whole shoot in about three weeks or a month's time, and after that only increase in thicknefs ; therefore during that period it would certainly forward them to give the ground an hoeing, though it was dug in the spring; and if the beginning of May should prove dry, which is some- times the case, it will be proper to give the plants a few gentle waterings. Be careful not to prune these trees after they are planted, for they will not bear it; and indeed their own beautiful natural shape indicates, that they want no afsistance from art. — SYCAMORE. In the autumn, when the keys are ripe, they may be gathered, and in a few days after •sown, as has been directed for the Ash. In spring the plants will appear, and make a shoot' of about a footjind a half by the autumn following, if the ground of the seminary be tolerably good, and they are kept clean from weeds. The spring after they come up, they should be planted in the nursery, in rows two feet and a half asunder, and their distance in the rows must be one foot and a half. Here they may remain till they are big enough to plant out for good, with no further trouble than taking off unsightly side-branches, and -digging between the rows. MAPLE. If a quantity of these trees are wanted, they may be raised in the same manner as the Sycamore, and managed accordingly. MULBERRY This tree is propagated two ways; by seeds, and by layers. Where the former can be procured, it is the most expeditious way of raising great quantities; and whoever has a correspondence in the south of France, or in Italy, may, through that channel, obtain them. Having the seeds ready, let a fine warm border of rich mellow earth be prepared ; and let this border be hooped, in order to support mats to defend the young plants, at their first appearance, from frosts. If no such border can be easily had, it will be proper to make a gentle hot-bed, and cover it with rich fat mould : This also must be hooped as the border. Then sow the seeds in little drills, about a quarter of an inch deep. The middle of March OF FOREST-TREES. 47 S. Your plants beginning now to peep, should be earthed up, and chap. rr. comforted a little, especially after breaking of the greater frosts, and v-^~y""w/ when the swelling mould is apt to spue them forth ; but when they are about an inch above ground, you may, in a moist season, draw them up is the best time for this work ; and when the young plants appear, which will be in about six weeks, they must be constantly covered with mats in the night-time to guard against the effects of frost. During the summer they should be kept clear from weeds, and covered from the extreme heat of the sun while the hot months continue. Whenever any cloudy or rainy weather approaches, the mats should be always taken off, that the plants may enjoy the benefit of it. By thus carefully nursing the beds, keeping them clear from weeds watering the plants in dry seasons, covering them from the parching sun, and uncovering them again in the night, or when the weather is cloudy or rainy, the plants by autumn will be got pretty strong ; though not so strong as to be left to themselves. The following winter they will require some care. When the frosts approach, they must be carefully- covered with the mats, as in the spring; for without this protection many of them would be injured, and the greatest part killed, at least down to the ground. In tills bed they may stand two years, when they will be strong enough to plant out in the nursery. The ground for this purpose being double Jug, the young plants should be set in rows, at two feet and a half distance, and one foot and a half asunder in the rows. There they may- remain till "they are of a sufficient size to plant out for good. HORNBEAM. In the autumn the seeds are ripe ; when, having gathered a sufficient quantity for the purpose, let them be spread upon a mat a few days to dry. After this, they should be sown in the seminary, in beds four feet wide, with an alley of about two feet, in the manner directed for raising the Ash. In this bed they will remain till the second spring, when they will make their appearance. During the summer of their concealment, the weeds should constantly be plucked up as soon as they peep; for if neglected the fibrcs- of their roots will strike so deep as to occasion many of the seeds to be drawn out on- weeding the ground. After the young plants appear, they should constantly be kept clear of weeds ; and if they were now and then gently refreshed with water in drv weather, it would prove highly serviceable to them. In the spring following they may be taken out of these beds, and planted in the nursery. MOUNTAIN ASH, OR QUICKEN -TREE. Having procured a sufficient quantity of berries, they should be sown, soon after they, are ripe, in the seminary, about half an inch deep, in beds made as before directed : they frequently lie till the second spring before they make their appearance. In the spring, following let them be taken from the seed-bed, and planted in the nursery. 4* A DISCOURSE i where they are too thick, and set them immediately in other lines or beds prepared for them; or you may plant them in double fofses, where they may abide for good and all, and to remain till they are of a compe^ tent stature to be transplanted; where they should be set at such distances The commen Birch is raised from seeds, and the varieties are continued by layers. The seeds should be gathered in the autumn before they drop from their scales, which will happen soon after they begin to open. In a day or two they should be sown in the semi- nary, in a superficial manner ; and after they are come up, the plants should be carefully kept clear of weeds for the first summer. The spring following they may be planted out in the nursery: the rows must be two feet and a half asunder, and the plants a foot and a half distant in the rows. Here they may continne till they are of a sufficient size to be planted out where they are to remain. SCOTCH FIR, -Having obtained a quainty of good seeds, let them be sown in beds ef light loamy mould, sometime in the beginning of April, or sooner, if the weather be favourable. In about six weeks the young plants will make their appearance, and then is the time to watch them carefully; for if the sparrows, or other birds, once find them out, they will destroy them as faijt as they come up. In order, therefore, to secure the crop, it will be proper to have the beds well netted soon after being sown, and strings of sewelling drawn acrofs. As ■soon as the plants are come up and have parted with their husks, the netting and sewel- ling may be removed : all this summer the beds must be kept clear of weeds, and in the latter end of the following March, or beginning of April, the plants must be pricked out, at the distance of four inches from each other, into beds properly prepared. After re- maining in these beds two years, the plants should be removed into the nursery, where they should be planted in rows three feet'asunder, and the trees one foot and a half distant in the rows. In this place they must continue till they are required to be planted out for .good. And here it will be proper to remark, that bleak and cold situations require the .firs to be planted from the seed-bed ; of which a particular account is given in the twenty- second chapter of the first book. WILD PINE. This tree may be raised in the same manner as the Scotch Fir ; and the cones should be prepared and the seeds obtained according to the directions given for that tree. They should also be sown at the same time,; and in about six weeks the young plants will ap- pear. They will make a short shoot the first summer; and in the spring following they •should be pricked out in the nursery beds, at a foot asunder each way. After your plants .have taken to the ground they will want no farther care than keeping them clean of weeds, till the latter end of September, or beginning of April following; in either which months they -shpuld be planted out for good, if pofsible ; but if the ground cannot be got ready for their OF FOREST-TREES. 49 as their several kinds require: but if you draw them only for the thinning chap. ii. of your Seminary, prick them into some empty beds (or a plantarium v'"*~'^ purposely designed) at one foot interval, leaving the rest at two or three. reception, they must undergo a second removal in the nursery way, otherwise they will mostly die when planted out ; for it is difficult to make this tree thrive when grown large, if it has not been used to constant moving. WEYMOUTH PINE. Weymouth Pines being the most beautiful and most valuable of all the different sorts, every Gentleman should plant some of them ; it is from these trees that our ships are furnished with masts; the trees now produce good seeds here, therefore may be procured in greater plenty than they used to be. If these seeds are not sown in boxes or pots, which is by much the best way, they must be covered with mats in the heat of the day, during the violent heat of the summer, and uncovered every night ; but if sown in pots or boxes, they will be more easily moved into the shade in summer, and brought back to a warmer situation in winter. April is the season for sowing thefe and other Pines. After the plants are come up, sift some earth amongst them, if they appear weak, or are beaten down after heavy rains, and before winter, sift some ashes over them : then in spring plant them out into beds six feet wide, at eight inches asunder each way : there let them remain two years, being constantly weeded, and the earth frequently stirred up with a small hoe, and before winter spread some ashes among them. The second spring they must be planted out into rows, eighteen inches asunder, and each row at three feet distance, where they may stand two or three years; and if they are not then intended to be planted out where they are to remain, they must be taken up, and planted again at two feet distance from each other, and the rows three feet asunder. This tree will bear planting out when six or eight feet high ; though not so many will live as when planted at a lower standard. SWAMP PINE. Its propagation is the same as the Weymouth Pine; and the planting out, and after- tnanagement of the trees, is also similar. STONE PINE. The Stone Pine produces large eatable seeds, and from their size they can easily be planted at what distance you please. In spring make some drills an inch deep, and at six inches asunder ; in these plant the seeds about four inche3 from each other, and cover them with the eartli near an inch thick. In dry weather the plants should be gently wa- tered, and kept clean from weeds until the ibllowing spring, when they should be planted out in rows, two feet asunder, and one foot in the rows, v\here they must continue two years ; after that they must be removed to where they are to remain, for they will not bear transplanting large.

When your seedlings have stood thus till June, bestow a slight Vy-*-v-"*-// di°-- upon them, and scatter a little mungy half-rotten litter, fern, bean-haume, or old leaves among them, to preserve the roots from scorching, and to entertain the moisture ; and then in March following SPRUCE FIR In the beginning of April, having got the feeds out of the cones, which are very long, let them be sown in a North border ; for when they come up, by being constantly shaded all the summer in such a situation, they will shoot much stronger, and be better to prick out the spring following in the nursery. In about six or seven weeks after sowing, the young plants will appear, when they should be screened with the usual care from the birds, which otherwise would soon destroy them. By the Autumn many of these young plants if they are kept clean from weeds and watered in dry weather, will have shot two or three inches ; and in spring they should be carefully removed out of their seed-beds, taking care that the fibres be not broken off or injured. Being thus cautiously taken up, they should be as carefully planted in the nursery-ground, at the distance of one foot asunder each way. Here they may continue, with keeping them free from weeds, for two or three years, when they should be set out in the places where they are designed to remain. SILVER FIR. These trees are raised by sowing the seeds in a shady border, about the beginning of April. They will readily come up if the seeds are good ; but as this is not often the case they should be sown very close, otherwise we may depend on having a very thin crop. The succeeding summer the plants will require no trouble, except keeping them clean from weeds; and the spring after that, they should be pricked out in beds at about four inches distance from each other. There they may stand for two years, when they should be planted in the nursery, in rows a foot asunder every, way. The year, or at farthest two years, after having been set in the nursery, they should be planted out for good; for if they are continued longer, many of them will die when planted out, and those which grow, frequently lose their leading-shoot, or meet with so great a check as to be hardly able to get into a growing state for several years. STRAWBERRY TREE. The Arbutus, or Strawberry Tree, is best propagated by seeds ; therefore when the fruit is ripe it should be gathered, and mixed with dry sand to preserve the seeds till the time of sowing. These seeds should be sown in pots, which should be plunged into an old bed of Tanner's bark that has lost its heat, covering the bed with glafses, &c. to keep out the frost. This should be done in December, and as the spring advances, if the pots are refreshed with water, the plants will come up the beginning of April, when they should be frequently, but sparingly, watered, and constantly kept clean from weeds. As the summer advances, if the plants are shaded in the heat of the day, it will greatly promote their growth ; but in warm weather they must be exposed all night to receive the dew, OF FOREST-TREES. si (by which time it will be quite consumed, and very mellow) you shall chap. ii. chop it all into the earth, and mingle it together. Continue this procefs ~*~*~*- . for two or three years succefsively, for till then the substance of the kernel will hardly be spent in the plant, which is of main import; but so should only be covered in the middle of the day : with this management the plants will rise to the height of five or six inches the first summer. The beginning of October, the plants may be shaken out of the pots, and their roots carefully separated, planting them singly in small pots filled with light earth; then plunge the pots into an old bed of Tanner's bark, under a common frame, observing to shade them from the sun in the middle of the day, and to give them water as they may require: in this bed the pots should remain during the winter, observing to expose the plants to the open air, at alt times when the weather is favourable; but in frofly weather they must be covered, otherwise they will be in danger, if the season prove severe. The spring following, the plants may be removed to a very gentle hot-bed, which will require no other covering but mats. This will enable them to make strong shoots early in the summer, whereby they will be in abetter condition to bear the cold of the succeeding winter: in this bed the plants may continue most part of the summer; for if the pots are taken out and set upon the ground, the smallnefs of their size will occafion the earth in them to dry so fast, that watering will scarcely preserve the plants alive; but if they are kept growing all the summer, they will be more than a foot high by the next autumn: it will also be advisable to screen them from the frost during their continuance in pots, by plunging them into the ground in a warm place, and covering them with mats in bad weather. When the plants are grown to be two or three feet high, you may shake them out of the pots, and plant them in the open ground in the places where they are to remain; but this should be done in April, that they may have time to form good roots before the winter; and as all the earth about the roots may be thus preserved, there will be no fear of succeeding at this season. HAW-THORN. As soon as gathered, let the Haws be buried about a foot thick in a dry trench, and to prevent their heating it will be proper to mix some earth with them. Then cover them with earth of a sufficient thicknefs to keep out the wet. In this situation let them remain two winters and one summer, and early in March sow them in beds properly prepared. In the course of the summer the seeds will come up plentifully. Having stood a year in the seed-bed, let the plants be pricked out in heds -of fresh earth early in the spring, at the distance of four inches from each other; and during the summer they must be kept clean, for the goodnefs of the Quick depends a great deal upon that operation. After remaining two years in those beds, the plants will be of sufficient size to plant out for hedges. Some persons recommend the Haws to be sown immediately upon being gathered, but that method is attended with many inconveniences. 02 53 A DISCOURSE then (and that the stature of your young imps invite) you may plant them forth, carefully taking up their roots, and cutting the stem within an inch of the ground, (if the kind, of which hereafter, suffer the knife,) set them where they are to continue : If thus you reduce them to the distance of forty feet, the intervals may be planted with Ash, which may be felled either for poles or timber, without the least prejudice to the Oak : Some repeat the cutting, we speak of, the second year, and after March (the moon decreasing) recut them at half a foot from the surface, and then meddle with them no more : But this (if the procefs be not more severe than needs) must be done with a very sharp instrument, and with care, lest you violate and unsettle the root; which is likewise to be practised upon all those which you did not transplant, unlefs you find them very thriving trees; and then it shall suffice to prune off the branches, and These observations upon sowing are taken from approved Authors that have wrote for the Southern Parts of this Island, which may account for the great distances recom- mended in planting from the seed-bed into the nursery. Nurserymen in the Northern Counties do not allow much more than half the distance here recommended, and probably the greater coldnefs of their climate may make it necefsary to crowd the plants closer together. Some other differences may be remarked, which, in like manner, may be accounted for from the difference of climate. Having thus given some particular directions for forming the Seminary, and afterwards stocking it with plants, it will be required to say something concerning the Nursery into- which the infant seedlings must be removed at proper seasons, in order to train them for planting out. And in fixing upon a proper piece of ground for this purpose, I recommend it to be a rich, deep, and stiffish mould, notwithstanding that the trees must afterwards be removed into a poorer soil. Reason teaches, that young trees, growing luxuriantly and freely in a good soil, will form vigorous and healthy roots, whereby they will be qualified to nourish themselves well ; and when they come to be afterwards planted into worse lands, they will be enabled, from the strength of their constitution, to feed themselves freely with coarser food. On the contrary, young trees, raised upon poor land, by having their vefsels contracted, and their outward bark mofsy and diseased, will be a long time, even after being removed to a rich soil, before they attain to a vigorous and growing state: and as this is suggested by reason, experience confirms it to be true. Having fixed upon a proper place, large enough to contain the quantity of trees wanted, let it, in the first place, be well fenced, either with hedges sufficient to keep out cattle, or pales or walls to keep out rabbits or hares; for without such defence a nursery will soon be demolished. In October or November, trench the land two spits deep, and in spring turn it over again ; after which let the surface be smoothed, and laid oat in quarters for the reception of the different trees taken from the Seminary. OF FOREST-TREES. 53 spare the tops; for this does not only greatly establish your plants, by chap. ir. diverting the sap to the roots, but likewise frees them from the injury s^~y-*»"/ and concufsions of the winds, and makes them to produce handsome, straight shoots, infinitely preferable to such as are abandoned to nature and accident, without this discipline : By this means the Oak will become excellent timber, shooting into straight and single stems: The Chesnut, Ash, &c. multiply into poles, which you may reduce to standards at pleasure. To this I add, that as oft as you make your annual trans- planting out of the nursery, by drawing forth the choicest stocks, the remainder will be improved by a due stirring and turning of the mould about their roots. But that none be discouraged, who may, upon some accident, be desirous or forced to transplant trees, where the partial or unequal ground does not afford sufficient room or soil to make the pits equally capacious (and so apt to nourish and entertain the roots, as where are no impedi- ments,) the worthy Mr. Brotherton, (whom we shall have occasion to mention more than once in this treatise,) speaking of the increase and improvement of roots, tells us of a large Pinaster, two feet and a half in diameter, and about sixty feet in height, the lowest boughs being thirty feet above the ground, which did spread and flourish on all sides alike, though it had no root at all towards three quarters of its situation, and but one quarter only into which it expanded its roots so far as to seventy and eighty feet from the body of the tree : the reason was, its being planted just within the square angle of the corner of a deep, thick, and strong stone-wall, which was a kind of wharfing against a river running by it, and so could have nourishment but from one quarter. And this 1 likewise might confirm of two Elms, planted by me about thirty-five years since ; which being little bigger than walking-staves, and set on the very brink of a ditch or narrow channel, not always full of water, wharfed with a wall of a brick and half in thicknefs to keep the bank from falling in, are since grown to goodly and equally spreading trees of near two feet diameter solid timber, and of stature proportionable. The difference between these, and that of the Pine, being their having one quarter more of mould for the roots to spread in ; but which is not at all disco- vered by the exuberance of the branches in either part. — But to return to planting where are no such obstacles. 54- A DISCOURSE 5. Theophrastus, in his third book de Causis, cap. vii. gives us great caution in planting to preserve the roots, and especially the earth adhe- ring to the smallest fibrils, which should by no means be shaken off, as most of our gardeners do, to trim and quicken them, as they pretend, which is to cut them shorter ; (though I forbid not a very small topping of the straggling threads, which may else hinder the spreading of the rest ;) not at all considering that those tender hairs are the very mouths and vehicles which suck in the nutriment, and transfuse it into all the parts of the tree ; and that these once perishing, the thicker and larger roots, hard and lefs spungy, signify little but to establish the stem ; as I have frequently experimented in Orange-trees, whose fibres are so very ob- noxious to rot, if they take in the least excefs of wet : and therefore Cato advises us to take care that we bind the mould about them, or transfer the roots in baskets, to preserve it from forsaking them ; as now our nursery-men frequently do, by which they of late are able to furnish our grounds, avenues, and gardens in a moment with trees and other plants, which would else require many years to appear in such perfection. In this case the earth is already applied, and fitted to the apertures and mouths of the fibres ; but it would require some time to bring them in appetite again to a new mould, by which to repair their lofs, furnish their stock, and proceed in their wonted ceconomy, without manifest danger and interruption ; nor lefs ought our care to be in the making and drefs- ing of the pits and fofses into which we design our transplantation, which should be prepared and left some time open to macerating rains, frosts, and sun, that may resolve the compacted salt, (as some will have it,) render the earth friable, mix and qualify it for aliment, and to be more easily drawn in and digested by the roots and analogous stomach of the trees : this, to some degree, may be artificially done, by burning of straw in the newly opened-pits, and drenching the mould with water, especially in over dry seasons, and by meliorating barren ground with sweet and comminuted laetations Let therefore this be received as a maxim, never to plant a fruit or forest-tree where there has lately been an old decayed one taken up, till the pit be well ventilated and furnished with fresh mould. 6. Pliny, the author of the Natural History, tells us, it was a vulgar tradition in his time, that no tree should be removed under two years old, or above three. Cato would have none transplanted lefs than five OF FOREST-TREES, 55 fingers in thicknefs*; but I have showed why we are not to attend so chap. ii. long for such as we raise of seedlings. In the interim, if these directions v-*-v-"»'' appear too busy or operose, or that the plantation you intend be very ample, a more compendious method will be the confused sowing of Acorns, &c. in furrows, two feet asunder, covered at three ringers depth,' and so for three years cleansed, and the first winter covered with fern without any farther culture, unlefs you transplant them: but, as I showed before in nurseries, they should be cut an inch from the ground, and then let stand till March the second year, when it shall be sufficient, to dis- branch them to one only shoot, whether you suffer them to stand, or re move them elsewhere. But to make an efsay what seed is most agree- able to the soil, you may,, by the thriving of a promiscuous semination, make a judgment of Quid quxque ferat regio, et quid quaeque retuset. ' What each soil bears, and what it does refuse. Transplanting those which you find least agreeing with the place, or else by copsing the starvelings in the places where they are newly sown, cause them sometimes to overtake even their untouched contemporaries. Something may here be expected about the fittest season for this work of transplanting : of which having spoken in another treatise*, as well as Pomona. in divers other places throughout this of Forest-trees, I shall need add little, after I have recommended the earliest removals, not only of al] the sturdy sorts in our woods, but even of some lefs tender trees in our orchards,. Pears, Apples, Vulgar Cherries, &c. whilst we favour the de- licate and tender Murals, and such as are pithy, as the Walnut, and some others. But, after all, what says the plain Wood-man, speaking of Oak3, Beech, Elms, Hawthorns, and even what we call Wild and Hedge-fruit ? " Set them," says he, " at All-hallon-tide, and command them to pros- " per ; set them at Candlemas, and intreat them to grow." Nor needs it explanation. 0 Cato does not fay, that no trees ought to be transplanted thai are lefs than five fingers in thicknefs : His directions only regard the manner of transplanting trees that arc five fingers in thicknefs. 56 A DISCOURSE 7. But here some may inquire what distances I would generally afsign to transplanted trees ; to this somewhat is said in the ensuing pe- riods, and as occasion offers ; though the promiscuous rising of them in forest-work, wild and natural, is to us, I acknowledge, more pleasing 'than all the studied accuracy in ranging of them ; unlefs it be where they conduct and lead us to avenues, and are planted for vistas, (as the Italian term is,) in which case, the proportion of the breadth and length of the walks, &c. should govern, as well as the nature of the tree; with this only note, that such trees as are rather apt to spread than mount, as the Oak, Beech, Walnut, &c. be disposed at wider intervals than such as grow best in consort, as the Elm, Ash, Lime-tree, Sycamore, Fir, Pine, &c. Regard is likewise to be had to the quality of the soil for this work : V. G. If trees that affect cold and moist grounds be planted in hot and dry places, then set them at closer order; but trees which love dry and thirsty grounds at farther distance. The like rule may also guide in situations exposed to impetuous winds and other accidents, which may serve for general rules in this piece of tactics. In the mean time, if you plant for regular walks, or any single trees, a competent elevation of the earth in circle, and made a little hollow, like a shallow basin, for the reception of water and refreshing the roots, will be required; sticking thorns about the edges, to protect them from cattle, were not amifs. Fruit-trees, thus planted, may be set round with beans, which will produce a small crop and shade the surface, perhaps, without detriment; but this more properly belongs to the garden. Most shrubs of Ever-green, and some trees, may be planted very near one another ; Myrtles, Laurel, Bays, Cyprefs, Yew, Ivy, Pomegranates, and others, also need little distance, and indeed whatever is proper to make hedges; but for the Oak, Elm, Walnut, Firs, and the taller timber-trees, let the dismal effects of the late hurricane, never to be forgotten ! caution you never to plant them too near the mansion, or indeed any other house, that so, if such accident happen, their fall and ruin may not reach them. 8. To leave nothing omitted which may contribute to the stability of our transplanted trees, something is to be premised concerning their staking, and securing from external injuries, especially from winds and cattle; against both which, such as are planted in copses, and in ample woods, arc sufficiently defended by the mounds and their closer order, OF FOREST-TREES. 57 and made fast to one another by short pieces above and beneath, in which chap, i i. a few brambles being stuck, they will be abundantly secured, without ^^^^*p/ that choaking or fretting, to which trees are obnoxious that are only single staked and bushed, as the vulgar manner is; nor is the charge of this so considerable as the great advantage, if we consider the frequent reparations which the other will require. Where cattle do not come, I find a good piece of rope tied fast about the neck of trees upon a wisp of straw to preserve it from galling, and the other end tightly strained to •a hook or peg in the ground (as the shrouds in a ship are fastened to the masts) sufficiently stablishes my trees against the western blasts without more trouble ; for the winds of other quarters seldom infest us : But these cords had need be well pitched to preserve them from wet, and so they will last many years. I cannot in the mean time conceal what a noble person has afsured me, that in his goodly plantations of trees in Scotland, where they are continually exposed to much greater and more impetuous winds than we are usually acquainted with, he never stakes any of his trees, but upon all disasters of this kind, causes only his servants to redrefs and set them up again as often as they happen to be overthrown, which he has affirmed to me, thrive better than those which he has staked; and that at last they strike root so fast, as nothing but the ax is able to prostrate them : And there is good reason for this, in my opinion ; for these concufsions open the mould for the more ready insinuations of the roots in quest of nourishment. It is in another place I suggest, that transplanted Pines and Firs, for want of their penetrating tap-roots, are hardly consistent against these gusts after they are grown high, especially where they are set close, and in tufts, which betrays them to the greater disadvantage ; and therefore such trees do best in walks, and at competent distances, where they escape tolerably well. Such therefore as we. design for woods of them, should be sowed and never removed. In the mean time, many trees are also propagated by cuttings and layers; the Ever-greens about Bartholomew-tide; other trees within two or three months after, when they will have all the sap to afsist them. .Every body knows the way to do it is by slitting the branch a little way, and then to plunge it a foot under good mould, leaving as much of its extremity above it; and if it comply not well, to peg it down with an Volume J, P &8 OF FOREST-TRESS. hook or two, and so when you find it competently rooted, to cut it- off beneath, and plant it forth ° « Other expedients there are, by twisting the part, or baring it of the rind ; and if it be out of reach of the ground, to fasten a tub or basket of earth near the branch, .filled, with a succulent mould, and kept as fresh as may be. For cuttings, about the same season, take such as are about the bignefs of your thumb,, setting them a foot in the earth, and near as much out. If it be of soft wood, as Willow, Poplar, Alder, &c. you may take much larger truncheons, and 0 There are various ways of layering trees, by which they may be multiplied. In order to raise great quantities, a sufficient number of trees should be set, in order to be headed down for stools. The ground, previous to planting, should be double dug; and the distances the trees ought to stand from each other should vary according to the size, height or manner they are intended to grow before they are layered. The autumn after plantings each tree should be headed to within a few inches of the ground; and the summer following kit will afford you plenty of young shoots proper for layering in the autumn. Neverthelefs, in many trees, it will be the best way to wait two years before you layer them, as each stool will afford you ten times the number of layers for the purpose ; and the shoots being then many of them side-shoots, and weaker than the strong shoots from the stool the autumn before, will,, for the most part, more readily strike root : for it is often observed^ that in very vigorous and strong shoots, of one year's growth, after they have been layered a twelvemonth even by slit-layering, the end of the divided part has only swelled, and struck no root; whereas smaller branches on the same tree, in the same space of time, have struck good root, and commenced plants fit to be taken off and removed to the nur- sery. If the tree has grown from the siool two years, it must be splashed, to bring the head and, branches down to the ground S all branches which crofs, crowd, or any ways incommode each other must be taken out, the ground should be hollowed, and the head of each branch brought into the hollow, pegging it down firmly with a strong peg. The ends of the young shoots must be also shortened ; for one eye only, for the most part, ought to be out of the ground, if you can tell how they will fall, as it will be a safer way to do it before the slit is made than afterwards. Then the slit, or twist, or whatever method you choose, must be entered upon; and when all the branches have undergone the operation, the mould must be carefully brought in among them, filling all the inter- stices, and levelling the whole so that an eye of each may just appear above ground ; and if any shoot has been left too long, it may now be shortened, holding it steady with the left thumb and finger, and cutting off an eye above the ground with the right. When the stool is completely layered in this manner, proceed to the next; and so on till the whole be completed. By waiting two years after the heading of the plant for the stools, (fools which perhaps would hardly have afforded you six plants, will now yield sixty, or more^ which is a sufficient encouragement for patience; nay, it is what ought to be practised by Jiurserymen, or gentlemen who want to raise large quantities -of trees for sale, or to be- OF FOREST-TREES. 59 so tall as cattle may not reach them ; if harder, those which are your.g, small, and more tender ; and if such as produce a knur, or burry swelling, set that part into the ground, and be sure to make the hole so wide, and point the end of your cutting so smooth, as that, in setting, it violate and strip none of the bark ; the other extreme may be slanted, and so treading the earth close, and keeping it moist, you will seldom fail of succefs. By the roots also of a thriving, lusty, and sappy tree, more may planted out on their own estates. And when this is the case, two quarters of sufficient size should be planted for stools, which coming in alternately, there will be an annual crop of layers for the purpose wanted. As soon as the layers are taken off, all scraggy parts should be cut off from the stools ; the heads should be refreshed with the knife ; and two years after, each stool will afford you a sufficient quantity of branches to be layered afresh; during which time the ground should be dug between the stools every winter ; and in spring and summer the weeds should be hoed and cleared off, as often as they make their appearance. Trees of much larger growth than two or three years may be splashed, brought down, and layered in this manner; and when they are grown too large for splash- ing, .or the nature of the wood will not bear such an operation, they may be thrown on their sides. In order to effect this, the mould must be cleared away from the roots, ou the side you intend the head to be brought down ; and on this side a sufficient number of the roots must be cut, that the tree may be brought to the ground, leaving proper roots to continue it in a growing state; but for this very few will be sufficient. When the tree is brought down, all the young branches are to be layered in the former manner ; and the year following, after they are taken off, the tree may be set upright again, cutting off all scraggy parts, side branches that had been beat down, &c. and if you put fresh mould to the roots, it will put out as fresh as ever, and may, if you please, afterwards undergo a second operation in the like manner. If Magnolias, or large leafy Evergreens, are layered in this manner, and the place is not well defended, it will be highly proper to make a stake-hedge of good height, at a small distance; otherwise the high winds having power on their large leaves, will frequently break them off before they have taken root. Layers may be procured from trees of any size, by building scaffolding of proper height, to support tubs or pots filled with good earth, in which to layer the young branches : but this method is never practised unlefs on some very scarce tree, which is desired to be continued in its upright state, in as much beauty as pofsible. Neither, indeed, does it deserve to be adopted, unlefs on some such extraordinary occasions, not only on account of the expence of building the scaffolding, but of the constant trouble there will be in keeping the mould in the pots of a due moisture; for being elevated in that manner above the ground, it will dry very fast; and if it be not constantly watered, there will be little hope of your layers striking root in any reasonable time. — Layering may be performed different ways; and trees of different texture are with different degrees of difficulty made to strike root. It is ■chiefly the young shoots of the preceding summer that the operation should be performed P 2 69 A DISCOURSE be propagated; to effect which, early in the spring, dig about its foot, and finding such roots as you may with a little cutting bend upwards, raise them above ground three or four inches, and they will in a short time make shoots, and be fit for transplantation ; or in this work you. may quite separate them from the mother roots, and cut them off. By- baring likewise the bigger roots discreetly, and hacking them a little, and then covering them with fresh mould, suckers may be raised in abundance ; which drawing competent roots, will soon furnish store of on ; though all wood of a loose texture or spungy nature, if several years old, will grow" very well. The different ways of layering are : 1. By only laying the shoot, whether young or old, and covering it over with fine mould. No other trouble than this slight layering is necefsary for the increase of numbers of trees and shrubs. — 2. By twisting the shoots and slightly breaking the bark, numerous trees, which would not so readily take by the former method, will emit roots from the bruised parts; and, if the work be performed tn the autumn, the shoots will commence good plants by the autumn following. 3. By; thrusting an awl through the joint, the young shoots of many trees will sooner emit fibres, from such wounded, part, than if they had been otherwise laid in the ground ; and in the course of the summer months will commence good plants, fit to be taken off and planted, out. — 4. Cutting out some small slips of bark, about a joint, will facilitate the shoot's, striking root, and cause it the sooner to commence a plant. — 5. Twisting of wire round the shoot, and pricking it in each side with an awl, has been recommended : some consider the twisting as an unnecefsary trouble, when the places are pricked with the awl, as the fibres always proceed from the wounded places, and not from the parts surrounded by the wire. — 6.. Slit-layering, or that operation generally known among gardeners by the name of Tongue-layering, is the most universal, the best, and the safest way of layering trees and plants. It is known to every florist, who layers his carnations this way : and is practised by all gardeners for almost all sorts of trees which are not known to take by the simple method of barely laying the shoots in the ground. It is performed by cutting with the knife halfway through the shoot at right angles with it, and then turning the edge of it upwards, in a perpendicular direction, along the middle of the shoot, half an inch, an inch, or more, according to the nature of the stock that is to be layered. The hori- zontal cut in carnationTlayering, is always at a joint, and is for the most part practised by making the cut at a joint or end, where the performance is on trees. The more elegantly to perform this,, make the horizontal cut half through ; take out the knife and insert it below that cut, on the heel of the underwood, taking it off and drawing the edge of the knife up the middle to the above length- By taking the heel of the underwood off, the tongue or bottom of the layer will sit more at ease ; and by being surrounded with mould, will be the better disposed to strike root, should the parts by any accident be made to elose again. The shoot being cut in this manner, should be next pegged down into the ground, a place being hollowed for the purpose ; then the point of the layer should be brought forward, pointing towards the stem of. the plant, which will separate the tongue OF FOREST-TREES. 61 plants, and this is practicable in Elms especially, and all such trees as chap. n. are apt of themselves to put forth suckers ; but of this more upon occa- ^— **f**A sion hereafter. And now to prevent censure on this tedious and prolix introduction, I cannot but look on it as the basis and foundation of all the structure rising from this work and endeavour of mine ; since from station, sowing, and continual culture and care, proceed all we really enjoy in the world. Every thing must have birth and beginning ; and afterwards, by diligence and prudent care, formed and brought to shape and perfection. Nor is it enough to cast seeds into the ground, and leave them there, as the Ostrich p does her eggs in the Lybian sands from the other part of the branch ; and to keep it at a distance, a small chip, or such like thing, may be inserted near the top of the slit, to keep it open. The mould must now be applied ; and after heading the layer down to within one eye or more of the ground, the businefs is done; in all layering, watering must be applied in summer to keep the ground moist, if dry weather should happen. The ground must always be kept clean from weeds • and there are few trees, if layered in this manner in the autumn, and with this manage- ment, w-hich will not be ready for taking up the autumn following. Layering on different plants may be performed at all times of the year ; though, in general, the best season for it is in the autumn : neverthelefs it may be done succefsfully for the most part in the winter or spring; and such plants as are found not to take readily by being layered at that season, should be layered in June or July, while they are tender, and performing their summer's shoot ; but as the shoots will then be soft and herbaceous, they must not be loo much watered, for that will cause them to rot; therefore it will be a better method to- cover the surface over the layers with mofs, which will prevent the soil from dr} ing too fast, so that a little water, now and then, will be sufficient. A large share of the vege- table creation may be multiplied by planting only their slips or cuttings in the eartli and affording them management suitable to their respective natures. Some trees grow so readily this way, that it is the only method practised to raise any desired number of plants. The Willow, the Alder, the Poplar, &c. in all their varieties, are instances of the larger kinds; whilst Sage, Rosemary, the Rue-plant, and Southernwood, are same instances of the lower ligneous plants, that are, with the utmost facility, multiplied by slips. These will grow if planted at any time of the year ; but such as will not prove so obsequious to> your discipline, you must indulge in the season they require to be set in ; the autumn for some, the spring for others ; the early part of the summer for one plant, and the latter end of it for another; all which various circumstances will be particularly described. under the article of the respective trees. * It is commonly reported that the female Ostrich deposits her eggs in the sand, and covering them up, leaves them to be hatched by the heat of the climate, and then permits the young to shift for themselves. Very little, however, of this history is true; no- bird has a stronger affection for her young than the Ostrich, and none watches her eggs. 62 A DISCOURSE boo'k i. without minding them more; (because nature has deprived' her of under- > -w-y-^.- standing ;) but great diligence is to be used in governing them, not only ' till they spring up, but till they are arrived to some stature fit for trans- plantation, and to be sent abroad, after the same method that our child- ren should be educated, and taken care of from their birth and cradle; and afterwards, whilst they are under pedagogues and discipline, for the forming of their manners and persons, that they contract no ill habits, and take such plyes as are so difficult to rectify and smooth again without the greatest industry : for prevention of this in our seminary, the like care is requisite : whilst the young imps and seedlings are yet tender and and flexible, they require not only different nourishment and protection from too much cold, heat, and other injuries, but due and skilful manage- ment in drefsing, redrefsing, and pruning, as they grow capable of being brought into shape, and of hopeful expectation, when time has rendered them fit for the use and service required, according to their kinds. He therefore that undertakes the nursery, should be knowing notonty in the choice of the seeds, where, when, and how to sow them, but also in the time of gestation they require in the womb of their mother-earth before parturition, that so he may not be surprized with her delivering some of them sooner or later than he expects ; for some will lie two, nay three vears, before they peep ; most others one, and some a quarter, or a month with greater afsiduity. It happens, indeed, in those climates, that there is lefs necefsity for the continual incubation of the female; and she more frequently leaves her eggs, as they 'are in no danger of being chilled by the weather ; but though she sometimes forsakes them in the day, she always carefully broods over them in the night: and Kolben, who saw great numbers of them at the Cape of Good Hope, affirms, that they sit upon their eggs like other birds, and that the male and female take' this office by turns. Dr. Sparrman makes the same observation. Nor is it more true what is said of their forsaking their young after they are excluded the shell. On the contrary, theycung ones are not able to walk for several days after they are hatched : during this lime the old ones are very afsiduous in supplying them with grafs, and are very careful in defending them from danger ; nay, they encounter every danger in their defence. When pursued, this animal, instead of running directly forwards, and availing himself of his natural speed, takes his course in circles; while the hunters make a small course within, relieve each other, meet him at unexpected turns, and keep him thus employed for two or three days together : at last spent with famine and fatigue, and finding escape impofsible, he endeavours to hide himself from those enemies he could not avoid, and covers his head in the sand, or the first thicket he meets. The means used by this bird to escape from its pursuers, and the manner of its death, are the only things that can, with propriety, be cattad fiolishiirjs. OF FOREST-TREES.

Those of hard shell and integument will lie longer buried than others ; for so the Libanus Cedar, and most of the coniferous trees, shed their cones late, which sometimes remain two winters and as many summers, to open their scales glued so fast together, without some external application of fire or warm water, which is yet not so natural as when they open of themselves 9: The same may be observed of some minuter seeds, even among the Olitories, as that of Parsley, which will hardly spring in lefs than a year; so of the seed of Beet, part in the second and third month, which, upon inspecting the skins and membranes involving them, would be hard to give a reason for r.

These Terrae-filii are what we call Timber-trees, -the chief subject of our following discourse. Trees are distinguished into subordinate species. Frutices, or Shrubs, are ligneous trees, though of a lower and humbler growth, lefs spreading, and rising up in several stems, emerging from the same root, yielding plenty of suckers, which being separated, and often carrying with them some small fibre, are easily propagated and planted out for a numerous store; and this, being clad with a more tender bark, seems to differ the frutex from other arboreous kinds ; since as to the shaft and stems of such as we account dwarf and pumilo, they rise often to tall and stately trees, in the more genial and benign climes '. Suffrutices are Shrubs lower than the former, lignescent, and more approaching to the stalky herbs Lavender, Rue, &c. but not apt to decay so soon, after they have seeded ; whilst both these kinds seem also little more to differ from one another, than do trees from them ; all of them consisting of the same variety of parts, according to their kinds and structure, covered with some woody, hard, membraneous or tender rind, suitable to their constitution, and to protect them from outward injuries ; producing likewise buds, leaves, blofsoms, and flowers, pregnant with fruit, and yielding saps, liquors, and juices, lachrymse, gums, and other exfudations, though diversifying in shape and substance, taste, odour, and other qualities and operations, according to the nature of the species.

It is allowed on all hands that animal con- OF FOREST-TREES. 65 Besides this general definition, as to what is meant by Trees, Fru- texes, &c. they are specially distinguished by other characters, viz. Leaves, Buds, Blofsoms, &c. but more especially by what they produce of more importance; by their fruit ye shall know them* The Glandiferae, Oaks, and Ilexes, yield acorns and other useful ex- crescences.— The Mast-bearers are the Beech, and such as include then- seeds and fruit in rougher husks, as the Chesnut-tree, &c. — The Walnut, Hasel, Avelans, &c. are the Nuciferae. — To the Conifera?, Resinifera?, and Squamiferze, belong the whole tribe of Cedars, Firs, Pines, &c. — Apples, Pears, Quinces, and several other Edulae fruits, Peaches, Apri- cots, Plums, &c. are reduced to the Pomiferaj. — The Baccifera? are such as produce Kernels, Sorbs, Cherries, viz. Holley, Bay, Laurel, Yew, Juniper, Elder, and all the Berry-bearers. — The Genista? in general, and such as bear their seeds in cods, come under the tribe of Siliquosa?. — The Lanuginosa? are such as bed their seeds in a cottony down. ccption is performed by the junction of the male and female; but it has remained a doubt with some, whether the union of the sexes be as elsential in the propagation of vegetables. The great Linnaeus has formed his noble system of Botany upon the certainty that all plants have male and female organs, either growing upon the same tree, or upon different trees of the same species: his method is distinguished by the name of the Sexual System, and is now universally acknowledged. On its first appearance, it was received with all that caution that becomes an enlightened age ; and Nature was traced experi- mentally through all her variations before it was universally afsented to. Tournefort refused to give it a place in his system ; and Pontedcra, though he had carefully examined it, treated it as chimerical. The learned Dr. Alston, Profefsor of Botany in the University of Edinburgh, violently opposed it ; but the proofs which Dr. Linnaeus has given amongst the aphorisms of his Fundamenta Botanica, and farther illustrated and explained in his Philosophia Botanica, are so clear, that the mind does not hesitate a moment in pro- nouncing animal and vegetable conception to be the same: there is, however, this difference ; in animals fruition is voluntary, but in vegetables necefsary and mechanical. Another and more striking proof of the analogy between plants and animals may be drawn from observations made in their infant states, at which early period they seem nourished and protected in a similar manner. For this the curious reader is requested to consult the note upon page 27, in which he will find sufficient proofs to convince him, that every blade of grafs which he contemptuously treads upon, has been nurtured in its infancy by the hand of Providence, with as much care, and in the same manner, as Man himself with all his pre-eminence of station.

" Mast-bearing trees were princi- u The OAK, the pride and glory of the forest, demands our first attention, whether we confider the dignity of its station, or the variety of uses to which it is applied. Being a native of our island, it adapts itself in a wonderful manner to almost every soil; and, if well defended in its infancy, there are few places in which it will not grow to a national advantage. The Oak naturally delights in a rich, deep, and loamy soil; but lands of that quality are now more profitably employed in pasture and tillage. However, there are large portions of land in this kingdom which yield but a small profit to the owners. Such wastes, if situated near rivers, or navigable canals, are nobly calculated for raising Oaks, which, at some distant period, may launch themselves into the Ocean, Guardians of Liberty and Commerce. Of the Oak there are fourteen species, of which number nine are deciduous and five evergreen. 1. QUERCUS (robvr) foliis deciduis oblongis superne^ latioribus, sinubus acutioribus: angulis obtusis. Lin. Sp. Plant. 1414. Oak -with oblong deciduous leaves., broader toward the fift, laving acute indentures, ■with obtuse angles. The coxmow oak. This is the common English Oak, which, for ship-building and other (Economical uses, far excels all the kinds in the known world. The /following is a variety, but Mr. Miller con- siders it as a distinct species under the title of QUERCUS (fcemiva) foliis deciduis oblongis obtusis, pinnato-sinuatis petiolis brevifsl- mis, pedunculis glandorum longifsimis. Oak -with oblong, obtuse, deciduous leaves, -which are winged, sinuated, and have very short foot-stalks, with the fruit growing vjion long foot-stalks. The FEMALE OAK. Mr. Miller observes that this sort is not fo common as the first, and he informs us, that in the Wilds of Kent and Sufsex there may be seen many large trees of this kind. According to him, the leaves are not so deeply sinuated as those of the common Oak, nor are they so irre- gular, the indentures being opposite, like the lobes of winged leaves ; these have scarce any foot-stalks, but sit close to the branches ; the acorns stand upon very long foot-stalks. The timber of this kind is accounted, by some, better than that of the first, and the trees, when growing, have a more lofty appearance.

The trunk rises nearly as high as the common Oak ; the branches extend very wide on every side, and are covered with a greyish bark, inter- mixed with brown spots ; the branches are closely garnished with oblong oval leaves, about three inches long, and almost two broad, which are deeply sawed on their edges ; most of the saws or teeth turn backward, and terminate in acute points. The leaves are stiff, of a pale green on their upper side, and downy on their under ; the acorns have very large scaly cups which almost cover them ; the scales are ligneous and acute pointed, standing out a quarter of an inch ; some of the cups are as large as middling apples. 5.

Oak -with broad shiny leaves, -which are divided like the Esculus. The RED OAK. This sort grows naturally in Virginia, and in other parts of North America. It arrives at a large size in the countries where it naturally grows ; the bark is smooth, and of a grevish colour, but that on the younger branches is darker; the leaves are six inches Ions, and two and a half broad in the middle ; they are obtusely sinuated, each sinus ending with a bristly point, of a bright green, standing upon short foot-stalks. The leaves continue their verdure very late in autumn, so that unlefs hard frost comes on early, they do not fall till near Christmas, before which time they change their colour and become red. The acorns of this sort are a little longer, but not so thick as those of the common Oak. 6. QUERCUS (prikus) foliis obovatis utrinque acuminatis sinuato-serratis, denticulis rotundatis uniformibus. Lin. Sp. Plant. 1413. Oak -with oblong oval leaves, -which are hointed on both sides, and have solved sinuses, -with uniform roundish indentures. Quercus castaneae foliis procera arbor Virginians. Pluk. Aim. 309. The cheskut-leaved oak. This grows naturally in North-America, of which there seems to be two kinds ; one grows to a much larger size than the other, though this may be occasioned by the soil in which they grow. The largest sort grows in the rich low lands, where it becomes the largest tree of any of the Oaks in those countries : the wood is not of a fine grain, but is very serviceable ; the bark is grey and scaly ; the leaves are five or six inches long, and two inches and a half broad in the middle, indented on the edges, and have many transverse veins running from the midrib to the borders ; they are of a bright green, and so nearly resemble the leaves of the Chesnut-tree, as scarcely to be distinguished from them. The acorns of this sort are very large, and have short cups. The leaves of the other are not so large, nor so strongly veined, and the acorns are smaller and a little longer, which may arise from the soil. 7. QUERCUS (xicraJ foliis cuneiformibus obsolete trilobis. Lin. Sp. Plant. 1413. Oak with -wedge-shaped haves, having three -worn-out lobes. Quercus folio non serrato in sum- mitate quasi triangulo. Catesb. Car. I. p. 20. The black oak. This grows naturally on poor land in most parts of North America, where it never comes to a large size; the wood is of little value. The bark is of a dark brown colour ; the leaves are very broad at the top, where they have two waved indentures, which divide them almost into three lobes ; they diminish gradually to their base, where they are narrow ; they are smooth, of a lucid green, and have short foot-stalks. The acorns are smaller than those of the common Oak, and have short cups. Of this species we have a variety or two, one par- ticularly with trifid leaves, and another slightly trilobate, called the Black Oak of the Plains. 70 A DISCOURSE our common Oak ; whereas there be many species of that goodly tree, though we shall take notice only of the two which are frequent with us. These are, the Quercus Urbana, which grows more upright, and, being clean and lighter, is fittest for timber; and the Robur, or Quercus Silvestris, (taking Robur for the general name, if at least contra-distinct from the rest,) which, as the name imports, is of a vast robust and in- 8.

The bark of this tree is greyish, the leaves are of a light green, six or seven inches long, and four broad in the middle ; they are regularly indented almost to the midrib. The indentures are obtuse. The leaves have short-footstalks. The acorns greatly resemble those of the common Oak. 9. QUERCUS (piiellos) foliis lanceolatis integerrimis glabris. Lin. Sp. Plant. 1412.

Of this sort there are several varieties, which are all included under the appellation of W illow-leaved Oaks. 10.

The ilex, or ever-green oak. This species is generally known by the title of Ilex, or Ever-green Oak ; of which there are several varieties, differing greatly in the size and shape of their leaves ; but they all arise from acorns of the same tree, as Mr. Miller observes ; nay, the lower and upper branches of the same tree are frequently garnished with leaves, very different in size and shape from each other ; those on the lower branches being much broader, rounder, and their edges indented and set with prickles, but those o~n the upper are long, narrow, and entire, The leaves of this tree are from three to four inches long, and one broad near the base, gradually lefsening to a point ; they are of a lucid green on their upper side, but whitish and downy on their under, and are entire, standing upon pretty long foot-stalks ; these remain green all the year, and do not fall till they are thrust off by the young leaves in the spring. The acorns are smaller than those of the common Oak, but of the same shape. 1 1 . QUERCUS (gramvvtia) foliis oblongo-Ovatis sinuato-spinosis sefsilibus subtus to- mentosis, glandibus pedunculatis.

This kind of Oak grows plentifully in Spain, Provence, Languedoc, and along the Mediterra- nean coast. It is a tree of small growth, seldom rising above twelve feet. The leaves are oval and undivided ; they are smooth on their surface, but indented on their edges, which are armed with prickles like those of the Holly. It is feathered to the bottom, which gives it the appearance of a bushy Shrub. The acorns are smaller than those of the common Oak. From this tree are gathered the Kermes, with which the antients used to die their garments of that beautiful colour called Coccineus, or Cocceus, being different from the Purpura of the Phoenicians obtained from the testaceous fish called Murex. In course of timi the Murex became neglected, and the Kermes, we are now speaking of, was introduced. This sup- ported its reputation till the discovery of America, when it gave place to the Cochineal, an insect found in the Mexican woods upon a plant named by Linnaeus, Cactus Cochinilfifer. Both antients and moderns seem to have had confused notions concerning the origin and nature of the Kermes ; some considering it as a fruit, without a just knowledge of the tree which produced it ; others taking it for an excrescence formed by the puncture of a particular fly, the same as the common gall produced upon the Oak. Tournefort was of this number. — Count Marsigli, and Dr. Nisole, a physician of Mountpelier, made experiments and obser- vations, with a view to further discoveries, but did not perfectly succeed. Two other phy- sicians at Aix in Provence, Dr. Emeric and Dr. Garidel, applied themselves about the same time, and with greater succefs, having finally discovered that the Kermes is the body of an insect, after having undergone several transformations. The progrefs of these transforma- tions must be considered at three different seasons. In the first stage, about the beginning of March, an animalcule, no larger than a grain of millet, is perceived sticking to the branches of the tree, where it fixes itself, and soon becomes immoveable; at this period it grows the most, and swells with the sustenance that it draws in : this state of rest seems to have de- ceived the curious observer, it then resembling an excrescence of the bark ; during this period of its growth, it appears to be covered with a down, extending over its whole body like a net, and adhering to the bark ; its figure is convex, not unlike a very small Sloe; in 72 A DISCOURSE and becoming yellow at the fall, do commonly clothe it all the winter the roots growing very deep and straggling. The author of Britannia Baconica speaks of an Oak in Lanhadron-Park in Cornwall, which bears constantly leaves speckled with white, and of another called the Painted Oak : others have since been found at Fridwood, near Sittingbourn in Kent; as also Sycamores and Elms in other places, mentioned by the such parts as are not quite hid by this soft garment, many bright specks are perceived of a golden colour, as well as stripes running acrofs the body from one place to another. At the second stage, in April, its growth is completed, when it becomes round resembling a pea in shape. It has then acquired more strength, and its down is changed into dust, and seems to be nothing but a husk or a capsule, full of a reddish juice, not unlike discoloured blood. Its third state is towards the end of May, a little sooner or later according to the warmth of the climate. The husk appears full of small eggs, lefs than the seeds of a poppy. They are properly ranged under the belly of the insect progrefsively placed in the nest of down that covers its body, which it withdraws in proportion to the number of eggs : after this work is performed, it soon dies, though it still adheres to its position, rendering a further service to its progeny, and shielding them from the inclemency of the weather, or the hostile attacks of an enemy. In a good season they multiply exceedingly, having from 1800 to 2000 eggs, which produce the same number of animalcules. When observed by the microscope in July or August, that which appeared as dust, are so many eggs or open capsules, as white as snow, out of which ifsues a gold coloured animalcule, of the shape of a cockroach, with two horns, six feet, and a forked tail. In Languedoc and Provence the poor are employed to gather the Kermes, the women letting their nails grow for that purpose, in order to pick them off with greater facility. The custom of lopping off the boughs is very injudicious, as by that means the next year's harvest is destroyed. Some women will gather two or three pounds a day ; the great point being to know where they are most likely to be found in any quantity, and to gather them early with the morning dew, as the leaves are more pliable and tender at that time than after they have been dried and parched by the rays of the sun. Strong dews will make them fall from the trees sooner than usual. When the proper season pafses, they fall off of themselves, and become food for birds, particularly piceons. Sometimes there will be a second production, which is commonly of a lefs size with a fainter tinge. The first is generally found adhering to the bark, as well as on the branches and stalks ; the second is principally on the leaves, as the worms choose that pat where the nutritious juice preserves itself the longest, is most abundant, and can be most easily devoured in the short time that remains of their existence, the bark being then drier and harder than the leaves. Those who buy the Kermes to send to foreign parts, spread it on linen, taking care to sprinkle it with vinegar, to kill the worms that are within, which produces a red dust, which in Spain is separated from the husk. Then they let it dry, pafsing it through a searce, and make it up into bags. In the middle of each, its proportion of red dust is put into a little leather bag, and belongs to the buyer; it is then ready for transportation, being always in demand on the African coast. The people of Hinojos, Bonares, Villalba, and other parts of the kingdom of Seville, dry it on mats in the sun, stirring it about, and separating the red dust.

The same is done with the husks ; but these are but of half the value of the dust. The Kermes of Spain is preferred on the coast of Barbary, on account of its superior goodnefs. The people of Tunis mix it with that of Tetuan, for dying these scarlet caps so much used in the Levant. The Tunesians export every year above 150,000 dozen of these caps, which yields to the Dey a revenue of 150,000 hard dollars (33,7501.) per annum for duties ; so that, exclusive of the uses of the Kermes in medicine, it appears to be a very valuable branch of commerce. — In some years it has produced 30000 dollars (5000 1.) to the inhabitants of Xixona in Spain. The first who has spoken of these insects with any accuracy is Peter Quiqueran, Bishop of Senez, in his book de Laudibus Provincial, 1550. 13. QUERCUS (suber) foliis ovato-oblongis indivisis serratis subtus tomentosis, cortice limoso fungoso. Lin. Sp. Plant. 1413. Oak with oval, oblong, undivided leaves, saitxd and ■woolly on their under side, and a fungous cleft bark. Suber latifolium perpetuo virens.— C. B. P. 424. The cork-tree. The leaves of this useful species are entire, of an oblong oval, about two inches long, and one and a quarter broad, sawed on their edges, and have a little down on their under sides ; their foot-stalks are very short ; the leaves continue green through the winter 'till the middle of May, when they generally fall off just before the new leaves come out, so that the trees arc very often almost bare for a short time. The acorns are vejy like those of the common Oak. The exterior bark of this tree is the cork, which is taken off from the trees even' eight or ten years; but there is an interior bark which nourishes the trees, so that the stripping off the outer is so far from injuring them, that it rather prolongs their life; for those whose bark are not taken off, seldom last longer than fifty or sixty years in health; whereas the trees which are barked every eight or ten years, will live a hundred and fifty years and more. The bark of the young tree is porous and good for little ; however it is necefsary to take it off when the trees are twelve or fifteen years old, without which the bark will not be good, and after ei
