I. Address delivered at the Thirty-seventh Annual Meeting, 5th August 1890. By Mr D. F. Macxenziz, Morton Hall, Vice-President. GENTLEMEN,—In the absence of the President of our Society, I am called on to make the customary Address from the Chair, and I think I cannot make a better use of the opportunity than to draw your attention for a short time to the large extent of what is called “Waste Land” in Scotland, and the amount of the same which could be profitably devoted to the growth of Forest Trees. Scotland is very irregular in outline, being so broken up by promontories stretching far into the sea, and by arms of the sea deeply indenting the land, that a great portion of the interior lies within less than forty miles from the sea. This accounts, to a large extent, for the difficulty in getting timber to grow at such high altitudes as it often does on the Continent. The superficial area, according to the Board of Trade, is computed to be 30,463 square miles, or 19,496,133 statute acres; but the final results of the Ordnance Survey give the figures at 19,777,490 acres of land and water. The latter includes lakes, rivers, rivulets, and per- manent pools down to the horse-pond. It also includes land or beaches along the seaboard, and estuaries to low-water mark. Such are the details laid down by the Ordnance Survey Depart- ment, from whose works, and the Board of Trade Returns, the figures Iam about to submit to you have been taken; but, for VOL. XIII. PART I. A 2 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. the sake of saving time, I adopt those of the Board of Trade for the cultivated areas, and the Ordnance Survey for the other details. In order to find the total area suitable and available for the profitable growing of timber, we have to deduct the area under crops of all kinds, woodlands, gardens, nurseries, towns, villages, houses, railways, roads, and water, as also those portions of our glens and mountain sides that are profitably grazed by sheep and deer. This done, we will have found the actual area of waste land ; I mean waste in comparison to what it might be if suitably employed. From this area we must deduct all high-lying exposed parts of our hills and mountains, quite unsuitable for the profit- able growing, or even the growth, of any kind of timber. This latter is regulated not so much by the height as by the distance inland, and the position of the mountain ranges, whether lying across the track of the prevailing winds of the district or along their path. Very good examples of this fact are to be met with at Rothiemurchus, Abernethy, Duthil, and Braemar, where the pine is to be found flourishing at an altitude of over 2000 feet above sea-level; and also in a large track of country in the county of Aberdeen, from near Huntly to Alford. Many more instances could be mentioned to illustrate this point, but enough has been given for our purpose. I now come to the figures. As already stated, the total area of Scotland is computed to be 19,496,133 acres imperial, of which, according to the Board of Trade Returns, Ordnance Survey, ete., 4,739,000 acres are under crops of all kinds, including grass ; under woods, 830,000 acres ; and gardens, orchards, and nurseries, 6920 acres; while towns, houses, roads, railways, paths, and walls take up 1,093,300 acres; water, lakes, rivers, etc., 1,026,337 acres; and 1,260,021 acres are profitably grazed by sheep and deer ; thus leaving 10,540,855 acres to be accounted for as semi- waste land. Of this latter area a large portion falls to be deducted as of no value for growing any kind of timber, viz., that portion of our island directly exposed to the storms from the Atlantic and North Sea, and the tops of mountains too high and exposed for the growth of timber. This portion alone takes up 1,950,000 acres or thereby, including in its area all the highest slopes of our northern and eastern seaboard, leaving 8,590,855 acres or thereby worth less, at the present moment, than 2s. per imperial acre. But we have here again to make a rather curious but important deduction, viz., those roads and strips of waste so very common ADDRESS BY THE VICE-PRESIDENT, AUGUST 5, 1890. 3 in the Highlands and elsewhere, too small of themselves to be profitably planted, but which are included in the Ordnance Survey measurements, and not given separately. I calculate the area of these to be, say, 146,322 acres. I may state that these latter figures are approximate, but are calculated on the basis of that found on given areas. Assuming these figures to be nearly correct, we are left with the still large surface of 8,444,533 acres highly suitable for the profitable production of first-class pine and other timber. This, then, proves so far the great loss we, as a nation, have sustained, are still sustaining, and are likely to sustain for a time, by not appropriating to our advantage the waste lands of our own country. The term waste land is perhaps a misnomer, as Jand can only be said to be waste by comparison with what its value might be under other and different circumstances and management—manage- ment more profitable to both the owners and the nation at large. There are few countries of the same population to a given area which have so large a proportion of their surface comparatively waste or “idle,” and so small a proportion of growing woods to the unit of population. This, no doubt, arises from the fact of our having an abundant supply of coal—wood for fuel being at a dis- count—and that there are no State forests or public interest in forestry. The public, as a whole, admire trees merely for their fine effect in the landscape, or the pleasant green of their foliage, and the shelter and shade they give in street, park, or highway —forgetting all the while, or not knowing or caring to know, the immense influence for good trees have on their welfare generally, and particularly by their sanitary influence, their extraordinary power of ameliorating a rigid and changeful climate, and regulating storms, thereby greatly prolonging life itself; whilst, looking at the case from a commercial point of view, nothing is more certain than if the area of our woodlands were increased even fourfold, the fertility of the remaining portion of waste would be so in- creased as to be able to support a much larger amount of live stock, and would give better crops and earlier harvests than at present. This is well understood in the district in which our meeting is being held—Easter Ross—as well as many other districts of Scotland, especially in the counties of Inverness, Aberdeen, Forfar, Perth, Berwick, and Roxburgh. Many parts of these counties are well wooded, not merely by large areas, but by the judicious arrangements of clumps, belts, etc. (we will see - 4 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. very good examples of this on the Fairburn estates), rendering valuable shelter to stock, thereby increasing the bulk of produce in a given time by about 30 percent. This is already so well known, that further example or reference is not required here. Apart from this view of the case, however, the increased area of woodland would give necessarily a large increase of work to that class—the crofters—who most require it, and who, as a rule, reside in the districts where such operations require to be most exten- sively carried out. Such increase would be of great advantage to the public at large, to the proprietors of the land, and to posterity —to the latter by retaining a large amount of the money sent out of the country to purchase that which we could produce for our- selves, and in many cases of a superior quality to that imported as “seconds” and “thirds,” the latter of which forms the greater bulk of our timber imports; and if you plant the 8,000,000 acres you find employment for 40,000 individuals. In conclusion, it may be observed that the areas are dealt with, in the Returns of the Board of Trade and by the Ordnance Survey, in such a manner as to fully account for every acre under its different heading, with the exception of those parts of the Ross- shire, Inverness, and Perthshire Highlands where sheep are allowed to roam at large on the most barren portions of the mountains. This is not only a loss to the stockmaster, but to the country, because, under such circumstances, the production of good mutton is limited by the exertion the animal has to put forth in order to obtain its living. The owners of such stock are, of course, not the least anxious to fatten it, because, they say, it pays them much better to breed than feed. This is the case under the present condition of the pastures, while, if large areas were planted, the result would naturally be different and better ; besides creating employment for a large number of people. “Men constitute the wealth of nations” if industrious, but the nation must produce the raw material, or pay smartly for finding it elsewhere. Gentlemen, if what I have stated to you will lead to further inquiry and action on the part of those who should be most interested, the landlords and the public, I shall not have spoken in vain. HOW TO COMBAT THE ATTACK OF INJURIOUS FOREST INSECTS. 5 II. How to Combat the Attack of Injurious Forest Insects. By Wituram SomervIL_e of Cormiston, D.(ic., B.Sc., F.R.S.E., Lecturer on Forestry, Edinburgh University.* The question which naturally suggests itself to our minds when we proceed to consider this subject is, “‘ Are our woods really attacked by insects in such numbers as to warrant our going to the trouble and expense of adopting special measures to meet their attack?” or, in other words, “Would the net gain to be derived from eradicating or materially reducing the numbers of our forest insects outweigh the loss which their presence in our woods in- volves?” Now, this question may be answered in one way or another, according to the peculiar circumstances of each case. Whether we would be justified in resting content with simply adopting precautions designed to prevent the undue increase of insects, depends upon the amount of success which has previously attended such measures, and upon the danger which former experi- ence and analogous cases would lead us to apprehend. Whether or not we would be repaid for going a step further, and waging a war of extermination against the insects which are already on our trees, depends upon the amount of damage which they are causing, and, in the event of their not being reduced in numbers, on the probabilities of their increasing to such an extent as to destroy a great deal more. In every case, too, we must take into considera- tion the nature of the preventive or remedial measures which can be applied, that is to say, whether they are cheap and easy of application, and effectual in operation. As to the question of damage, I am sure that all careful observers who have spent much time in our woods must have come to the conclusion that our forest trees sustain an amount of damage each year through the attack of insects, which not only justifies but imperatively demands our taking some steps to prevent the recurrence of such damage in future. In making this statement, let me assure you I am not indulging in the amusement of con- juring up a phantom in order to show you how expertly I can cause it to vanish, neither am I alluding to anything so indefinite and undemonstrable that I would experience any difficulty in 1 Paper read before the Royal Scottish Arboricultural Society at Dingwall, August 1890. 6 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. convincing even the veriest layman that much damage is being done, and that more is to be feared. For the proper understanding of this subject, some considerable knowledge of the habits and life-history of our forest insects is desirable, but perhaps I may, by taking a special case, be able to convince even the non-professional man that insects do play a very important and undesirable part in forest economy. Suppose we go into a middle-aged or old Scots pine wood some- time during winter, and proceed to examine the thick bark at the base of the trees, more especially of those that are semi-isolated or situated near the edge of the wood, we shall find that it is perfor- ated in exactly such a way as would result from the discharge of a gun loaded with No. 5 shot at a distance of about twenty yards. On following these perforations into the bark, we would find that they extended for an inch or so, but did not penetrate so far as the wood, and that each, or most of them, contained a small dark brown beetle in a semi-comatose condition, which we would have no difficulty in recognising as the well-known pine beetle (Hylur- gus piniperda). I fear that at this stage our non-professional friend would be apt to remark that if this small and apparently lifeless creature cannot show more destructive work than that of boring into the dead tissues of trees, it can hardly be said to have earned the amount of reprobation to which it has been subjected. So much I am prepared to admit, merely remarking that if not distinctly destructive, neither is it positively beneficial to tree growth in its winter quarters. Towards the end of March—a little later or earlier according to the character of the weather—the pine beetles withdraw from their winter quarters, and for the next two months are to be found under the bark of a certain class of tree. The conditions which the insects demand are very stringent, that is to say, so long as the conditions can be obtained, no trees will be attacked which do not fulfil these conditions. ‘The trees most in request are pines which are sufficiently old to be provided with thick bark, and which have been dead for a month or more. The thick bark is necessary, because the transition stage from larva to pupa being passed not between the wood and the bark, but actually in the bark, there would not be space for the accomplishment’ of this process were the bark not of a certain thickness, Trees in robust health are, under ordinary circumstances, free from attack, prob- ably because the insects are inconvenienced by the presence of HOW TO COMBAT THE ATTACK OF INJURIOUS FOREST INSECTS. 7. too large quantities of viscid resinous substances ; neither are trees infested which have been dead for a year or so, doubtless owing to the tissues being no longer suitable for the nourishment of the insects and their young. Why pines, and especially the Scots pine, are utilised by the insect for breeding purposes in preference to other trees can only be explained by the assumption that this particular insect has become gradually adapted for feeding in trees of this particular genus, just as the turnip fly only attacks crucifers, or Scolytus Ratzeburgi only birches. Suppose, now, that we had taken our incredulous friend into a wood in April or May, and, having found a Scots pine which had been blown down or felled during the previous winter, were to show him the characteristic galleries of the pine beetle underneath the bark, he would most likely remain unconvinced of our having made out a strong case against the insect. He might say, and so far it would not be easy to contradict him, that surely the boring of even a large number of small passages underneath the bark of trees already dead, could do no great amount of harm, more especially as even the surface of the wood was hardly touched. If we were to cease our attempts at conversion at this point, we would be forced to acknowledge defeat, but the better course to pursue would be to pause and consider what would happen if the insects were to be placed in circumstances which would enable them to increase in numbers at a rapid rate. Now, in the absence of exceptional disturbing causes, practically the only limit to the increase of this beetle, and of many other forest insects, is inter- posed by the want of proper material in which to oviposit ; that is to say, if a sufficient number of old Scots pines in a suitable state be provided, conditions are offered which enable the insect to increase in numbers to almost any extent. The most common cause of the production of a large quantity of breeding material is a severe gale, or a succession of severe gales such as we experi- enced in Scotland some years ago. At that time, as will be remem- bered, whole woods were levelled with the ground over wide areas of country, and for some years afterwards the timber could neither be cut up nor marketed. That, then, was an opportunity for //. piniperda, as well as for all bark beetles, to increase at a prodigious rate, and one which the results show they were not slow to avail themselves of. Let us look for a moment at the rate of increase of which such an insect as the pine beetle is capable when placed in the possession of an almost unlimited supply of breeding material. 8 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. Two beetles, a male and female, make a gallery in spring, and in it they deposit from 80 to 120 eggs; let us take the average and say 100. In ten weeks or so, these, having passed through the stages of larva and pupa, become beetles, of which 50 will be males and 50 females. In the same year, towards the end of July, these 50 couples proceed with the work of reproduction, each pair pro- ducing 100 young, so that by the end of the first year the numbers have increased from 2 to 5000. These beetles hibernate in the manner already described, and proceed to breed the following spring, when the 2500 couples will give birth to 250,000 indivi- duals, and these, reproducing themselves in the same year, will, before the autumn is past, have multiplied to no less than 12,500,000 head. In these calculations no allowance has been made for those which would be destroyed in various ways, but if we even deduct 20 per cent. from each of the broods, we are still left at the end of the second year with over five millions of pine beetles as the result of our having neglected to destroy the original pair. Some idea of the rate of increase may be gained in another way. Where pine beetles are abundant, the bark of suitable trees is undermined to such an extent that, on a large pine, scarcely a square inch will be found that is not occupied by the galleries of the parent beetles or their larve. From observations and measure- ments, I have calculated (allowing 40 square inches of bark to each family) that a large pine can produce quite 100,000 beetles, so that the leaving of ten large Scots pines, or of twenty average sized ones, lying on the ground, or standing dead in the wood, till the middle or end of July, is sufficient to ensure the birth of 1,000,000 pine beetles. Now, although comparatively little damage is done to timber during the breeding season, so long as the insect is represented by but small numbers, the case is entirely altered when a large increase has taken place, such as happened in Scot- land a few years ago. In the insect world the principle of ‘first come first served” receives striking illustration. Those beetles which first awake from their winter’s sleep exercise their usual discrimination, and oviposit only on thoroughly suitable material. It happens, however, when the insects are very abundant, that every particle of suitable Scots pine is occupied, with the result that late comers have to take what they can get, and are forced to oviposit on other conifers, such as the spruce, and, as I have found, on the larch as well.?| Under such circumstances, comparatively 1 Proc. Roy. Soc. Edin., vol. xvii. p. 255, HOW TO COMBAT THE ATTACK OF INJURIOUS FOREST INSECTS. 9 thin-barked pines are also attacked, and, worst of all, growing trees, especially such as are somewhat unhealthy, are no longer safe. Let me cite two instances of a large amount of damage being caused by this insect using growing trees for purposes of oviposi- tion. In the peninsula of Darss, in Pomerania, on the 12th and 13th of November 1872, the tide rose exceptionally high, with the result that a district stocked with Scots pines was more or less inundated. The effect of the sea-water upon the trees was to cripple their growth to some extent, and make them tempting objects for insect attack. During the next year or two pine beetles increased at an alarming rate, and totally destroyed all the pines on 2500 acres, A similar experience, on even a larger scale, is reported from France. In the Department Gironde Pinus maritima is largely cultivated, chiefly for the purpose of binding the drifting sands. In the hard winter of 1879-80 the trees suffered severely, and the pine beetles consequently appeared in enormous numbers. The result of frost and insects together was the destruction of timber to the value of £1,680,000. If any difficulty has been experienced in proving that JZ. piniperda is the perpetrator of an excessive amount of mischief when in its hibernation or breeding quarters, the task will be all too easy when we examine its life-lristory at other times. When the young insects hatched underneath the bark have reached the imago stage, they desert their birthplace and take to the young shoots of the pines, into which they bore, and usually cause their death. The damage is most apparent in plantations from fifteen to thirty years old, where it is no unusual thing to find that quite 50 per cent. of the trees have been deprived of their leading shoots again and again, and have been reduced from fine straight poles to little better than misshapen bushes. When this happens, and I am sure many instances of its occurrence must present themselves to your minds, the future prosperity of the wood can no longer be looked for, as it can, at the best, only produce poorly developed and badly formed stems. In old woods the work of the insect in this way is not less destructive, if somewhat less apparent. Here, too, the young shoots, both of stems and branches, are its feeding ground. Into these it bores its way, and weakens them to such an extent that they are easily broken off by the first high wind, and litter the ground in large numbers, I believe that squirrels are often 10 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. blamed for this work, but however destructive these creatures are in other connections, in this case at least the accusation is unjust. In old woods, where height-growth is nearly over, the damage chiefly consists in the loss of the organs of assimilation, namely the leaves, and the consequent reduction in the formation of wood. Owing to the loss of foliage, however, the fertility of the soil is also impaired, and, in a dry district especially, this consideration may be a very serious one. It would be difficult to estimate the amount of damage done in Scotland by the pine beetle alone, but at all events it must be enormous. I know no part of the country where it is not present in large numbers, and its presence can be detected as well from a railway carriage as from actual examination on the ground. Running through any district which suffered severely from recent gales, or one where forestry is practised in an irrational or careless fashion, one cannot fail to be struck with the miserable appear- ance of many of the old Scots pines, Instead of being provided with dense rounded crowns of dark-green foliage, they are thin and of a pale colour, and, protruding from amongst the leaves, may be seen the extremities of bare dead branches, symptoms clearly testifying to the presence of vast numbers of pine beetles. For the purpose of bringing before you the destructive work of forest insects, I have so far confined my remarks to the pine beetle, an insect, I am sure, familiar to you all; and my own conviction is that, even if this were the only insect which preyed upon our trees, the damage which it causes is far more than sufficient to compel us to adopt measures for its destruction and the safety of our woods. As you know, however, this is not the only foe which the forester has to fear in the insect world. To mention all would be a difficult if not an impossible task, and one which would take us far beyond the limits of time at our disposal. There are upwards of eighty European species of Scolytide (the family to which ZH. piniperda belongs), almost all of which prey upon trees or shrubs; then we have many species of Aphide, several very destructive weevils, including Hy/lobius abietis, the pie weevil, which is considered by many to be the most destructive of all our forest insects, and the caterpillars of many Lepidoptere and Hymenoptere. Mention must also be made of the cockchafer, which both in the imago and larval stages works fearful havoc amongst our forest trees. In France, during years when this HOW TO COMBAT THE ATTACK OF INJURIOUS FOREST INSECTS. 11 insect is specially numerous, it is said that damage is done to fields and forests which is estimated at £40,000,000. Seeing that forest insects are so numerous, and so varied in their methods of attack, it is manifestly impossible that, in a short paper like this, I can do more than briefly summarise the general and indicate a few of the special measures which can be adopted to eradicate or keep them in check. This subject may be conveniently treated in two divisions. We shall, first of all, look at such measures as are designed to keep insects in check, and prevent their ever increasing to such an extent as to threaten our woods with a calamity ; and, secondly, at remedial measures, to be put in force only when the others fail, or have been neglected, and danger is at hand. Measures for the prevention of the increase of forest insects are to be looked for as coming either from the side of the natural enemies of the insects or from the management of the woods. The natural enemies of insects are to be found in most divisions of the animal kingdom. Many insects live entirely, or for the most part, by preying upon other insects. Such creatures as lizards and frogs destroy insects in large numbers. Several mammals destroy large numbers of insects, but unfortunately many of them cause damage in some way or other which prevents our unconditionally advocating their encouragement. This is the case, for instance, with the fox, hedgehog, weasel, mole, and mouse, all of which devour insects in one form or other, but nevertheless whose presence in our woods cannot be regarded as altogether an unmixed good. The two most useful mammals in this country are probably the bat and shrew. Neither of these creatures does any appreciable amount of damage, and they subsist, one may say, all but entirely upon insects, and therefore deserve every encouragement to live and increase. The best friends of both farmers and foresters are undoubtedly to be found amongst the birds, many of which subsist entirely upon insects or their larve. A foremost place in the list, in point of individual usefulness, must be assigned to the cuckoo, which preys largely upon hairy caterpillars, insects which, for the most part, are avoided by other birds. It has been noticed, when caterpillars become very numerous in fields or woods, that cuckoos congregate in such places in large numbers, and, as they are extremely voracious, they do much to mitigate insect ravages. Unfortunately cuckoos are, on the whole, not very numerous 12 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. in this country, to which also they are only summer visitants, but they have the advantage over other birds that, being perfectly unimpeded in their movements by the cares and duties of incubation, they are always ready for action. The tree-creeper, common wren, gold-crested wren, and tits are great destroyers of injurious insects, which, on account of the small size, scansorial habits, and wonderful activity of these birds, are safe neither in the deepest bark-fissures nor on the most delicate of twigs. Their usefulness, therefore, no less than the charm they lend to our woodlands, renders these birds worthy of every protection. Then, we have swallows, pipets, wagtails, the hedge-sparrow, warblers, the redbreast, red-start, chats, fly-catchers, and the starling, all of which are useful in the highest degree, and, if we except the starling’s partiality for cherries, possess no bad qualities to detract from their merits. Many other birds, such as the rook, jackdaw, sparrow, finches, and owls, destroy insects when they come in their way or when no other food presents itself, but, on account of the damage which they cause to crops or game, they cannot be regarded as worthy of unconditional preservation, though, under certain circumstances, the advantages which their presence ensures may outweigh any drawbacks. Now, it must be borne in mind that it is not sufficient merely to preserve our useful birds from destruction, but means must also be taken to secure their increase. This may be accomplished in a variety of ways. During severe weather in winter, food must be supplied. Very suitable for this purpose are the clean- ings of grain or hay-seed, though for tits animal food, such as lard, must be provided. In order to set it beyond the reach of crows, dogs, cats, etc., it should be placed in the shell of a cocoa-nut or some such receptacle, and suspended by a string from the bough of a tree. The numbers of our useful birds may also be largely increased by providing them with suitable nesting and sleeping places. Many of the forester’s best friends only breed in holes, so that unless hollow trees, loosely-built walls, or artificial breeding-places are to be had, it is quite impossible for them to build their nests and rear their young. Holes in trees and walls are the places where, in this country, nearly all our hole-breeding birds are reared, but, as a general rule, such places do not offer great safety from the attacks of cats, weasels, and other predaceous animals, either to the parent birds or their brood. It is, there- HOW TO COMBAT THE ATTACK OF INJURIOUS FOREST INSECTS. 13 fore, much better to provide artificial nesting-boxes prepared from light boards coated with*tar, which can be so constructed, and fixed in such a position, as to ensure for their tenants perfect safety. A firm in Leipzig is prepared to supply any number of nesting-boxes at the average rate of 6d. each, a price which, I think, need not be much, if at all, exceeded in this country. In fixing the nesting-boxes on trees the following points must be observed :—For titmice the boxes must not be placed at a greater height than 12 feet from the ground. They should only be fixed on conifers, and, if possible, on dense conifers, such as spruces and silver firs. For red-starts and fly-catchers the boxes should be fixed on isolated trees, or on such as stand near the edge of a wood. In the case of boxes for starlings, any number may be fixed on the same tree, but in the case of all other birds there must not be more than one box on each tree. In all cases it is found that the best results follow when the boxes are fixed on the south or east side of the tree, the west side being the most unfavourable. So far as the system does not violate the principles of good sylviculture, all hollow trees should be allowed to stand, for not only do our useful birds find nesting-places in them, but they are also largely used by bats as sleeping-places. I may be allowed to mention an experiment I made last spring, and from the success which has already attended it, I hope to extend it next year. In the part of Scotland where the experiment was made there is a great scarcity of trees suitable for the nesting of our hole-breeding birds. We do not lack the hollow trees so much as the means of entrance into them, that is to say, there are plenty larches and spruces which are decayed at the centre, but which are useless to the birds on account of their hollow centres being surrounded by firm wood. Now, it is evident that such trees are of very little commercial value, but with a little ingenuity they may be made most valuable in another way. One has only, by means of a chisel or large augur, to pierce the wood and establish communication with the centre, to make all such trees nurseries from which a large number of titmice and tree-creepers will be sent forth annually. As such trees are, at the best, only fit for conversion into inferior paling-stobs, no real damage is done to the timber if the entrance holes be made at the height of a stob length, say 5 feet, from the ground, while the gain which ensues through the destruction of noxious insects 14 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. far outweighs any little trouble we may be put to in providing for the wants of the birds. Both titmice and tree-creepers breed twice in a season, and produce six to ten young on each occasion. Each bird, it is calculated, destroys two or three hundred thousand insects annually, chiefly in the form of very minute eggs. Five thousand insects are often sufficient to completely denude an average-sized tree of its leaves. If such defoliation be repeated a second year, the probabilities are that the tree will die. The annual produce of one breeding-place, say twelve titmice, can destroy two and a half millions of insects each year, which would be sufficient to entirely denude five hundred trees of their leaves. The preventive measures which we have considered come from the side of the enemies of the insects, the other set is more directly due to the management, and may naturally be subdivided into the following heads :— 1. The Establishment of the Wood.—Strong well-developed plants should be selected, as they are best able to withstand insect attack. In the case of danger from the attack of the pine weevil, only such young trees should be used as have been reared in comparatively open nursery lines, because plants which are much crowded when young have thin and delicate bark, and suffer very severely from this insect. Where a variety of trees thrive equally well, it is always advisable to cultivate mixed woods. This precaution is necessary, because, as a general rule, each species of insect prefers but one species, genus, or class of tree, and great calamities are only known in pure woods. It is scarcely necessary to say that great care must be exercised in inserting the plants in the ground, so that their growth may be interfered with as little as possible, for it almost always happens that the weakest plants are the first victims. One should also avoid as much as possible forming large compartments of wood of the same age. It is much safer to divide large woods into age-classes, because many insects confine their attack either to young or to old trees, but do not attack trees of all ages indifferently. 2. The Tending of the Wood.—Thinning should be begun before there is any chance of the density of the crowding interfering so much with growth as to weaken the vitality of the trees, but, at the same time, care must be taken that over-thinning is avoided, otherwise fertility suffers, and the evil we wish to avoid is encountered. During the operations of thinning, all trees which HOW TO COMBAT THE ATTACK OF INJURIOUS FOREST INSECTS. 15 are unhealthy, or which have been damaged by wind or snow, must be removed, and a watchful eye should constantly be kept on the woods, so that trees which appear likely to die are at once removed, as it is in such trees, or in trees which have just died, that destructive insects find their most congenial breeding-places. The practice of only removing trees from the wood some months after they have died does nothing to keep insects in check, for it is not dry and withered trees, but such as are still supplied with sap, that forest insects make use of for breeding purposes. 3. Harvesting the Timber.—Nothing conduces so much to the increase of many destructive insects as bad management in con- nection with felling and utilising forest produce ; and, conversely, woods which are well managed in this respect are preserved from the attack of many insects. The chief point to be observed is to get the felled timber removed from the wood, and marketed or converted as quickly as possible. Where any difficulty is expe- rienced in this respect, it should at least be peeled, and, if possible, peeled at a time when the bark is full of larve, for, by so doing, large numbers of destructive insects are got rid of, and the prac- tice, from being merely preventive, becomes remedial. These precautions are most necessary in the case of conifers, for it is in them that forest insects breed most abundantly. Where the ground is suitable the trees should be cut close to the ground, but where, as on steep declivities, this cannot be accomplished, the stools ought to be stripped of their bark. It is sometimes possible to get the bark removed without incurring any expense by allow- ing cottagersito strip it off for firing purposes, and the same holds true with regard to branches and the general refuse left after trees are felled. Not only do stools and branches supply breeding- places for Scolytidew, but also for weevils, hence the reason why Hylobius abietis is so destructive to young trees planted on land previously occupied by conifers. The preventive measures which have been noted do not by any means exhaust the list, though they are certainly the most important. Let me now say a few words with regard to measures for the general eradication of insects. Theoretically, insects may be destroyed during any or all of the four stages of their existence, that is to say, as eggs, larvee, pupe, or imagines, and also during any season of the year; but in practice the best stage or season to select depends upon the life- history of the insect to be destroyed. It is comparatively seldom 16 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. that the egg stage is selected, though an exception presents itself in the Black Arches moth (Liparis monacha). The larva stage is the one most commonly chosen, and is almost general in the case — of butterflies and moths. It is also frequently resorted to with beetles, e.g., the whole of the Scolytide, Melolontha vulgaris, etc. The pupa stage is not often selected, chiefly because it is usually of such short duration, and, on the whole, neither is the imago stage, though pine weevils, cockchafers, and certain moths are destroyed in large numbers as perfect insects. As a general rule, one is guided in the choice of the stage and season by that which offers the most opportunities, and for this reason the larval stage is most usually chosen, because many injurious insects pass the greatest proportion of their life in the state of larve, and are at that stage most easily caught. The destruction of forest insects may take place (a) when the insect is feeding, breeding, or hibernating in its natural haunts, or when moving to or from its breeding or feeding ground ; or (6) in special lures prepared to attract the insects to them for the purpose of feeding, breeding, or shelter. We shall now look shortly at some special eradicative measures which can be applied along these two main lines. Destruction of Forest Insects when in their Natural Haunts.—In countries where cockchafers, Melolontha vulgaris, are numerous, advantage is taken of every opportunity to destroy them, and huge numbers are captured by hand-picking. Early morning and dull days are chosen, because at these times the beetles are slow in their movements. The work is chiefly performed by women or children, who are paid at a certain rate per pound (1 lb. contains about 550 head). From reliable sources I have collected the following statistics to show what enormous numbers of cockchafers are from time to time collected. In 1836 a society for the destruction of cockchafers at Quedlinburg, in Saxony, paid out £40 for the capture of 33,000,000 ; in 1860 a private individual in Salzmiinde paid £45 for some 22,000,000 head. In 1864, in the neighbour- hood of Leipzig, over 378,000,000 were collected. In 1868 Saxony was practically overrun by cockchafers, and the secretary of the Central Chamber of Agriculture, Dr Stadelmann, issued a strong appeal for their destruction, at the same time issuing instructions as to how this might best be accomplished. The appeal was generally acted upon, with the result,that there were collected nearly 1400 tons, or a grand total of something like 1,600,000,000 head. In HOW TO COMBAT THE ATTACK OF INJURIOUS FOREST INSECTS. 17 Wurtemberg, in 1872, about 231,000,000 cockchafers were gathered and destroyed. Dead cockebafers have been put to the most varied uses. They have been proved to furnish first-class food for pigs and poultry, they form an excellent manure, and have also been employed in the manufacture of waggon grease and printing ink ; and a silver- amalgam work near Freiberg was for several years lighted with gas obtained from the dry distillation of cockchafers, The pine weevil is often captured in large numbers by hand- picking. This can be performed by children, who in early summer search the woods formed during the previous winter. The cap- tured insects are best placed in small bags, the mouth of each being furnished with a bottle-neck to prevent them finding their way out easily. Another method of catching pine weevils has many advocates, It is, however, only applicable to cases where the surface is fairly level, and the soil firm but not very stony. The modus operandi is as follows :—When a coniferous wood has been felled during winter, the area is, immediately after the removal of the trees, surrounded with a trench 10 to 12 inches broad and as many deep. The sides must be perpendicular, and as smooth as possible. At intervals of ten paces or so there are constructed, in the bottom of the trench, special pitfalls, 4 to 8 inches deep, These trenches must be visited every few days, and the captured beetles destroyed. As the trenches are apt to become damaged or silted up during heavy rains, they must be frequently examined, and, if necessary, repaired. The object of this method is the capture of all pine weevils which are making towards the fresh stools on which to deposit their eggs, as well as those which have been hatched there, and are proceeding to the adjoining young woods to prey on the trees. The system is largely employed in many parts of Europe, and where the conditions are favourable, it is both cheap and efficacious. In the trenches are captured not only pine weevils, but also other destructive weevils and insects generally, which are incapable of or averse to flight. The preventive measure employed in the case of the winter moth, Cheimatobia brumata, at present devastating the orchards in the west of England, falls under this heading. As is well known, the imago stage of this insect is attained under the earth, after which the wingless females proceed to crawl up the stems of fruit and other broad-leaved trees for the purpose of depositing their eggs in VOL. XIII, PART I. B 18 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. the buds. The most effectual way of destroying them consists in taking advantage of their natural habits, and interposing obstacles to their ascent of the trees by surrounding the base of the stems with rings of some viscid material, in which they stick and perish. Instances might be cited of other eradicative measures of the same nature as those already given, but enough has been said to indicate the general principles of such measures, and time compels us to hasten on to look at the other group. Destruction of Insects by means of Lures.—Measuvres of this kind are the most easily arranged and supervised, and are, generally speaking, the most effectual. They have this point in common, namely, that the insects are not actually sought for, but are induced to congregate in certain specially arranged places, where either they or their eggs, larve, or pup may be easily captured and destroyed. Pine weevils can be kept down, if not eradicated altogether, by laying out spruce or Scots pine logs, upon which the beetles deposit their eggs, and these, or rather the larvee which result from them, are afterwards destroyed. ‘lhe system succeeds best on ground previously stocked with conifers, where, however, the old stools have been trenched out. Fresh stems of spruce or pine 3 to 4 inches in diameter are selected, which are cut into blocks 4 or 5 feet in length, care being taken to preserve the bark as entire as possible. These logs are buried in the ground in the month of May, in such a way that the thick end is covered to the depth of a foot or so, while the thin end projects above the ground 2 or 3 inches. The soil and turf are afterwards replaced, and the whole firmed somewhat by tramping. About twelve such lures are enough for each acre, and in order to facilitate finding them, some sort of order should be observed in laying them down, and their position should be marked by wooden pins or stakes. In any case, such lures are largely made use of for oviposition, and when no old stools are present to act as counter-attractions, nearly every female pine weevil finds her way thither, and not only weevils, but many other destructive insects besides. In the month of October the blocks are carefully dug up, and the bark, with the larvee which it contains, is stripped off and burned. A lure of another kind is largely used in the destruction of pine weevils, which attracts the insects not for purposes of oviposition, but solely for food. This lure consists of sheets of the bark of the spruce or Scots pine of a convenient size, say 15 by 10 inches, HOW TO COMBAT THE ATTACK OF INJURIOUS FOREST INSECTS. 19 which are laid out, bast downwards, throughout the young wood, at distances of twenty paces or so. Underneath each sheet are placed a few young twigs of the Scots pine, which greatly assist in attracting the insects, and on the top of all is laid a sod or flat stone to keep the bark from drying up too quickly. The lures should be renewed and replenished two or three times during the season, as the old material is apt to lose its charm. Each morning from April till September, these traps are visited either by the forester, or, which is cheaper and equally suitable, by a boy or woman, and the beetles which are found are removed and destroyed. This is the best remedy for pine weevils that has ever been discovered, and is employed with conspicuous success wherever these creatures abound. The pine beetle, and all the other members of the great family of the Scolytide, can be best, and indeed only, eradicated through providing material on which they may oviposit, and in which their young may afterwards be destroyed. The procedure is very simple, and the results highly satisfactory. From February till September, at intervals of a month, trees, which in the ordinary course of things would be removed, are felled and allowed to lie for six weeks or so, at the end of which time they are peeled and the bark burned. The number of “ catch-trees” which one should prepare depends entirely upon the abundance of the insects. If it be found that all, or almost all, the available space in the trees is occupied by breeding galleries, then it is evident that too few trees have been provided. If, on the other hand, the catch-trees are not much attacked, then fewer may in future be laid dowu ; but on every well-managed estate a considerable number of such lures should always be present. One must also arrange the species of tree to be used as a lure according to the species of insect one wishes to destroy. The majority of the Scolytide infest pines, but Bostrichus typographus attacks the spruce almost exclusively, Scolytus destructor the elm, Hylesinus fraxini the ash, Scolytus Ratzeburgi the birch, etc., so that it may be necessary to prepare catch-trees of many species, though in the great majority of cases the Scots pine suflices. In connection with these lures, the greatest amount of care must be bestowed upon the selection of the right time in which to peel the bark and destroy the broods. If peeling be done too soon, the bark is not occupied by so many insects as it can afford space for, and consequently an excessive number of catch-trees 20 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. niust be prepared, entailing increased labour and greater expense. If, on the other hand, one delays too long before proceeding to strip the bark, many or most of the broods may have reached the imago stage, and have deserted their breeding ground, with the result that not only are the ends of the whole system frustrated, but the wood is actually left in a worse state than it would have been had no such lures been prepared. As it is unnecessary to remove the bark before the larve are half-grown, and unsafe to delay till the pup are formed, the best time to destroy the insects is towards the end of the larval stage, but better a week too soon than a day too late. It seldom happens that all the broods are found at the same stage of development at the same time ; but there must be no striking of averages, it is those that are furthest advanced which must guide the forester in his selec- tion of the right time to peel and burn. It is not now my intention to discuss the question of State interference in the destruction of forest insects. In many countries of Europe laws have been enacted to regulate forestal operations, so as to minimise the chances of an outbreak of forest insects, and also for dealing with an outbreak when such occurs. In this country, however, the State has, so far as I am aware, never interfered with regard to forest insects, nor, on the whole, do I consider that such interference would be desirable. That our management is none of the best cannot be denied, but with a system of more intensive forestry, I hope soon to see signs of decided improvement. In common with most other civilised countries, we have a Wild Birds Protection Act which has done good service in the past, and which only requires to be more stringently enforced to be capable of imparting still greater benefits in the future. ON BRITISH OAKS, 21 III. On British Oaks. By Joun Smitu, Romsey, Hants. Botanists divide the British oaks into three varieties, and hold that there is only one species indigenous to the British Isles, namely, Quercus robur ; the varieties being (1) Q. robur peduncu- lata, (2) Q. robur sessiliflora, and (3) Q. robur pubescens, or intermedia. The first of these, however, is the prevailing tree, and may claim to be the true “ monarch,” as most of the giants in our land are of the variety pedunculata. The distinctive features of the varieties are—(1) Pedunculata has no foot-stalks to the leaves, and the acorns are on long stalks. (2) Sessiliflora has stalks to the leaves, and short flower-stalks, hence its botanical name ; its common name being dur, or durmast oak. The timber is said not to be so durable, but the bark contains a percentage more of tannin, and it enjoys a greater immunity from insects than pedunculata. It occurs in Dean Forest, the New Forest, Sherwood, and in other parts of Great Britain. (3) Pubescens, or intermedia, may be distinguished from the last by the under- side of the leaves having short hairs, which, when the leaf falls, has a dull, leaden-like appearance ; and as this seems to be the only apparent difference, it is evidently only a variety of sesstilv- flora. In Hooker and Arnott’s “ Botany ” it is said : ‘‘ Dr Greville has shown that there is no connection whatever between the relative length of the fruit-stalk and the petiole. The flowers are sessile upon the peduncle in both varieties ; but in sesst/zflora it is mostly very short, or almost wanting, in pedunculata much elongated ; between these there is every gradation. Intermedia, or pubescens, is said to have the lobes of the leaves separated by obtuse angles; but both kinds may be observed on the same branch, and sometimes on the same leaf.” CoMPARATIVE VALUE. With regard to the comparative value of the timber of Q. r. pedunculata and Q. r. sessiliflora, leaving out pubescens, which is merely a variety of the latter, the merchant will give the same price for trees of equal size, so that there is really no difference in their value. But at the time when oak timber was in demand for the navy, sessiliflora, or the durmast oak, was not considered 22 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. fit for that purpose ; indeed, it was through the purveyors for the navy that the distinction was often drawn as to its inferior quality, being, it was said, more liable to dry-rot, and this tradition still lurks in the minds of the older woodmen, several tales being told and localities named as to how these worthy gentlemen were deceived into passing the durmast oak ; but in latter years, as I have said, it will command the same price. This being the case with regard to the buyer, it would seem that there is no differ- ence; but in looking at the matter from the seller or grower’s point of view, the case is different, as sessi//flora increases in bulk faster than pedunculata, and, taking the two trees mentioned at page 25 as representing the comparative rate of growth, we find that the former increases after the rate of 5 feet in ten years, whilst the latter increases only 3 feet in the same time; and, if we put this quantity at 2s. 6d. per foot, the money stands at 12s. 6d. and 7s. 6d. respectively. It has already been mentioned that the bark of sesstliflora contains a percentage more of tannin, but I doubt whether this can be appraised to any advantage, as a tree of pedunculata of equal size to the other will throw a greater weight of bark, the bark of sessilijlora being thinner, presumably owing to its more rapid growth. The timber of the oak is superior to that of any other native tree, and it has Leen said of it “that, although some of the other descriptions of timber may be harder, some more difticult to rend, some that can bear a horizontal or lateral strain better, none contains all these qualities united in such a superior degree as the oak.” Although the ‘wooden walls” are a thing of the past, still the price has not diminished ; indeed, the tendency is rather upwards. But the price of bark varies, as in some years it is so low that it scarcely pays expenses, whilst in other years it pays well. Much, of course, depends on the season being favourable or not. It would be hazardous to say whether the many substi- tutes which now and again crop up will ever entirely displace it for tanning purposes. A company with large capital has been recently started with the object of importing the boiled down bark of the spruce as a substitute—a hint which might be useful in this country for oak bark as well as spruce, for in certain seasons, especially wet ones, it would be a great saving to boil down the bark as soon as the trees are stripped, and cask the liquor for future use. ON BRITISH OAKS. 93 SoiL AND SITUATION. Oak will grow and come to perfection as a tree in almost any description of soil, provided it 1s not too wet, and has a depth of from 3 feet to 4 feet. But the best timber is produced on strong clay, resting on a subsoil of gravel or chalk. It will grow faster on lighter soils, but the timber is more lable to be shaky, and consequently not so good. Where the soil is not naturally suitable for the oak, it is a waste of money to attempt its cultivation. The situation of an oak plantation should be sheltered ; and when not naturally so, nurse trees, such as Scots fir, spruce, larch, or birch, should be introduced. I prefer the three last, as not so apt to overcrowd the oaks, but great judgment is required in this matter. Furze or whin has been recommended, and no doubt has some advantages, in that it is short-lived, and would decay when its shelter was no longer required ; but, on the whole, I prefer larch, or any fast-growing deciduous tree for sheltering the oak in its infancy. A belt of Scotch fir on the most exposed side may be advisable, there to remain until ripe. A practice has prevailed in the New Forest of Hampshire of planting the oaks with alternate rows of Scots fir, the rows running due north and south. This practice is evidently a failure, as the oaks are drawn up so spindly that they cannot support themselves. This is partly due to the fact of too many Scots firs being planted, and also to the want of timely thinning. The excuse for this last is the reluctance to cut down nice thriving plants before they are fit for some commercial purpose. Having selected a place on which to raise oak for timber, a question arises whether the acorns should be sown in the place where they are intended to remain, or whether they should be sown in a seed-bed, and afterwards transplanted. This question seems to be decided by the paper which Sir James Campbell, Bart., submitted—as the result of experiments in the Forest of Dean —to the International Forestry Exhibition at Edinburgh in 1884. In analysing this paper, I will first take certain periods ; and as the year 1822 saw four out of the six non-transplanted trees cut down, leaving but two, I will only deal with them, and taking the period of 38 years, that is, from 1784 to 1822, the increase was for— 24 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY.

Then take two of the transplanted for the same periods, as follows :— A had increased in 1822 to 262 in., or an average of 641 in. , In 1860 it had increased to 744 in., or an average of -936 in. B had increased in 1822 to 254 in., or an average of -664 in, , In 1860 it had increased to 69} in., or an average of “91 )-m: The first thing that strikes one with reference to the above is the great difference in size between the non-transplanted and those that were. In the 76 years “A,” a transplanted one, exceeded “LL,” a non-transplanted, -344 in. per annum, and “B” exceeded “ M” in the same time by ‘348 in. Now it is difficult to believe that the mere fact of transplanting would result in such a difference, all other conditions being equal, and this at the end of 76 years, without any other reason than that the tree was trans- planted. I have taken the period of 76 years, because I happen to be well acquainted with a selfsown wood of about the same age, and in 1888 measured several, with the following results :— No. 1 had a circumference of 60 in. at 5 feet up, or an average increase per annum of : ‘ *789 in. The bole or trunk was 60 feet, and the sheer height 80 feet. No. 2 had a circumference of 65} in., or an average increase per annum of nearly . ; 862 in. The bole or trunk 40 feet, and the sheer helt 80 feet. No. 3 had a circumference of 74 in., or an average increase per annum of : °970 in. The bole or trunk 30 feet, and ihe sheer height also 80 feet. ON BRITISH OAKS. 25 The above examples show that the length of the bole affects the circumference, that is to say, the longer the bole is the less the girth, and wice versa, and this leads me to remark that in Sir James Campbell’s paper the length of the bole is not given, an important omission. Another objection to this experiment has been stated, namely, that the plants left in the “acorn patch” were in exhausted soil, whereas the transplanted ones were put in comparatively maiden soil. An argument put forward in favour of transplanting is, that the tap root only serves a temporary purpose, and is of no consequence to the future growth of the tree. This opinion is founded on observations taken of uprooted trees, which have no appearance of tap roots. In answer to this it may be stated, first, that the absence of a tap root may have been the cause of the uprooting, because whether self-sown or planted, there may have been cir- cumstances in the subsoil unfavourable to its growth. Another omission in Sir James Campbell’s paper is that the variety of the oak is not given. Now I find that pedwneulata does not increase so fast as sess¢liflora. I found this opinion on the measurement, for ten years, of two trees which, so far as can be seen, are growing under precisely similar circumstances. No. 1. Quercus pedunculata, measured in 1878, had a circumference of . : “ 5 ED ft. The bole 9 ft. » Im 1888 the circumference was : : 12 ft. This gives an average increase per annum of : 1-2 in, No. 2.

Pili Or an average increase per annum of : : 2 in. nearly double that of No. 1, The soil in which they grow is clayey loam. Another Q. sessli/lora is increasing at the rate of 875 in. per annum ; but this is evidently an older tree than No, 2, and is growing on stiff clay. PLANTS AND PLANTING. Whether the foregoing statements as to the growth of the two oaks, which are natives of Britain, will bear out the theory that 26 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. sessiliflora grows faster than the other, it is still desirable to have a mixture of sessz/iflora in a plantation, for the reason that the bark of the thinnings is of more value, and would be almost the only return in the earlier years of the plantation. In preparing the land for planting, no better method can be adopted than to crop it with potatoes, which pulverises the soil better than the cultivation of any other crop. The oak plants, four or five years transplanted, should be put into pits at 4 feet apart each way, to be successful, and this operation will require to be carefully done. For the first three years the plantation should be hoed annually, after which tall weeds, brambles, etc., can be cut down as occasion requires. THINNING. The thinning may commence from the seventh to the tenth year, and here great judgment is required, as no hard and fast rule can be laid down. The only plan that can be recommended in the first thinning is to cut out the weakest plants, and if two or more robust plants are found side by side to leave them alone for another time. Before the second thinning, which may be taken in another seven or ten years, all the undergrowth should be cut clean out. The trees will now be, say, twenty years of age, and greater judgment, if possible, will be necessary at this thinning, as the proportions of the trees and their likelihood to become useful timber must be calculated with a skilful eye, and the fittest selected to remain. Some writers have recommended that a certain number per acre should be left, and that they should stand at equal distances apart. This is questionable advice, for in all probability there will be three classes of trees in the plantation, namely—first, those with a straight leader going ahead ; second, those with a short stem, and inclined to have a branchy head; and third, those which it would be difficult to class as a tree or shrub. These last should all be cut over, unless there are special reasons to the contrary, as the shoots from the stools will come in to be cut as underwood at the next thinning. The second class to have plenty of room to develop their head, as in consequence of their short stem they will be the first to come in as marketable timber. The first class may be left closer together ; two or more may be no farther than 8 feet apart, as many fine timber trees are found growing as close. In the third thinning proceed as in the second, and the cuttings of the underwood should now be of some ON BRITISH OAKS. Ti value. Care should be taken to leave all seedlings which may have sprung up, but none of the shoots from the stools should be left, however promising they may look, as trees grown from such are generally faulty at the butt, and otherwise unsatisfactory when they attain maturity. The trees being now about thirty years of age, some of the short stemmed ones will come in as useful timber, but no more should be taken out than is absolutely necessary to make room for the others, as no greater mistake can be made than in taking too many trees at a time. DISEASES OF THE OAK. Insects. The oak, although lord of the woods, is more subject to the attacks of insects than any other tree of the forest. One authority has stated that there are nearly 130 species of galls living on various kinds of oaks in Europe. In this paper it will be sufficient to notice only those that are common in Britain. First, the Marble Gall, so called from its appearance, being like a common marble as used by boys in play. It is perfectly round, brown, and gets very hard in autumn, and with clusters of three or four gives the tree a strange appearance when denuded of leaves. It occurs mostly on young trees, or those that have been pollarded, seldom or never on large growing trees. This gall is produced by an insect known as Cynips Kéllarz. Its history is somewhat obscure ; but the grub occupies the centre of the gall, and lies in a curved position, emerging from it In spring a perfect fly. During the winter many of the galls are pierced by birds and the grub extracted. This, no doubt, tends to check their increase. The Apple Gall, or ‘oak apple,” is occasionally very plentiful, and generally found at the end of a shoot. The galls begin to form at the end of April or beginning of May, and are full grown by “oak apple day,” or the 29th of May, the anniversary of the restoration of Charles II. Sometimes they are 1} inches in diameter, of a greenish-white colour streaked with red, at first soft, but harden somewhat before they fall from the tree ; they are then found when opened to contain many grubs, each in a separate cell, The perfect insect, Terax terminalis, emerges in July. The Root Gall—The females deposit their eggs in the roots 28 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. which they can reach near the surface of the ground. A large number of eggs are laid close to one another, and no doubt two or more females deposit their eggs so close together that they form one gall. The eggs are laid in August, and the galls begin to grow in September, but from the fall of the leaf until the spring they do not increase in size. In May they are full grown, but the gall flies do not emerge until the following April. The galls vary in size from about } of an inch to 3 inches diameter, and will be found full of small oval cells, each containing an insect. The flies which issue from these galls are known as Aphilotrix radicis, and only females appear in this generation. They are much larger than their parents, measuring nearly a quarter of an inch in Jength. They leave the galls in April or May, and deposit their eggs in buds which form the young shoots, causing swellings to appear at the base of the shoot, from which the flies emerge in August. This species, therefore, requires two years to complete the cycle of its transformation. The Artichoke Gall, so called from its resemblance in form to the globe artichoke. This is formed by an insect called Andricus pilosus. Both sexes appear in June, and the female lays a single egg ina bud, which causes it to grow into a scaly bract. On cutting open one of these galls the interior will be found of a woody texture, and partly embedded in the top is a small, hard, brown, oval striated gall, which contains the grub, This gall eventually falls to the ground, when the trans- formation of the insect is completed. In the woody portion of the outer gall may often be found cells containing grubs of some other species, which has laid eggs after its formation was begun. The perfect insects, Aphilotrix fecundatrix, bred from the internal galls, are about one-eighth of an inch in length, and always females. They appear in April, and attack the buds containing the male flowers, within which their eggs are laid. The galls which result are oval-pointed, about one-tenth of an inch in length, covered with stiff hairs, and of a green colour. The perfect insects, which are of both sexes, escape from the galls in June, and attack the leaf-buds as already mentioned. The Spangle Gall insect (Spathegaster baccarum) deposits its eggs on the underside of the leaf at the beginning of June, and the galls begin to form in July, and are full grown in September, when they are about three-tenths of an inch in diameter. They are flat and circular, with the centre raised in a flat cone. They are of a ON BRITISH OAKS. 29 greenish-yellow colour, with tufts of red-brown hairs, and some- times cover the entire underside of the leaf. They were very numerous in 1886. ‘The insects lie dormant during the winter, of course falling with the leaf. They appear in the winged form in April or May. The Button Gall (Spathegaster vesivatrix) is formed by a small species of about one-tenth of an inch in length, both sexes of which are produced, The female deposits her eggs on the under- side of the leaves in June, and the galls are about one-tenth of an inch in diameter. They resemble a small button covered with fine threads, which under the microscope are very beautiful. The flies do not emerge from the galls until spring, when only females are produced. These attack the undersides of the leaves, which causes small galls, somewhat resembling the oak spangles. The Currant Gall (Neuroterus lenticularis).—Vhis fly is about one-eighth of an inch long, and of a reddish-brown colour. The females deposit their eggs in the buds containing the male flowers, and also on the undersides of the leaves. The galls when mature are perfectly globular, of a transparent green, speckled with red, They are of a soft consistency, with a considerable hollow space in the centre, in which is the grub. When formed on the male flowers they resemble a bunch of currants. The flies emerge from the galls in June. Such is an account of the more common of the galls to be found on the oak in Britain; but what the effect is on the growth of the tree it would be difficult to say, as they have occurred in most years for ages past, with perhaps the exception of the marble gall, which is stated to be a more recent introduction. We now come to a more serious class of insect pests, namely, the caterpillars, chief among which is the Tortrix viridana, or oak-leaf roller. This caterpillar attacks the leaves, and has assumed alarming proportions at intervals of years apart, such as in 1831, 1848, 1864, and 1881. This gives a period of about seventeen years between each attack. I particularly noticed the latter years, but in 1888 their ravages were the most disastrous of any. On the lst of June in that year, a bright sunny day, I entered an oak wood, and, after proceeding a short distance, became conscious of being enveloped in cobwebs. On discovering the cause, so thick were the caterpillars hanging by their threads all around me, that I determined to return, and although the distance was but short, I emerged literally covered with them. During that month 30 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. they continued their ravages until whole woods were denuded of their foliage, and looked as bare as in mid-winter, and so annoying were they that labourers could not work in the woods. They also attacked the hazel under the oak, surrounding some of the bushes with their webs as if in a glass case. It was only in the close woods where the ravages took place, isolated oaks not being touched, The trees which enjoyed immunity, although surrounded by infested oaks, were the elm, beech, sweet chestnut, and the Turkey oak, and the ash partially. During the height of the attack I passed through a wood composed of Q. sesst/iflora, which, although the attack had been begun, they had left off evidently either poisoned or starved. This fact has also been noticed by a resident in the Forest of Dean, who, in writing of 1881, says, “ It was strikingly evident last summer that the Q. robur pedunculata, or old English oak, was attacked by blight more severely than the Q. r. sessiliflora. Single trees and groups of several together would be seen in full foliage, or but slightly injured, and, when examined, these were found to be of the last-mentioned variety, while all around them Q. 7. pedunculata would be leafless and bare.” This is another proof that sesst/iflora is distinet from pedunculata. On the 2d of July 1888 very heavy rain began to fall, and continued at intervals for a week. Then the trees that seemed to be dead began to sprout, and the mid-summer shoots soon clothed them in verdure again. Many of these shoots measured from 12 to 18 inches in length. Of the causes, or a cure for such a devastating attack, little can be said. A mild winter is generally reckoned a predisposing cause, but the winter of 1887-88 was not what might be called ‘ mild.” An analysis of the 61 days previous to the attack—that is, from the Ist of April to 1st June—shows that there were 18 days of frost, 2 on which snow fell, 20 on which rain fell, and 8 classed as cold or ungenial, thus leaving only 13 days of moderate temperature, or warm, June 5th was remarkably cold, and snow fell in Scotland and parts of England. Now this record is not consistent with the ‘‘ mild season” theory. A writer, in noticing the attack of 1848 in the Forest of Dean, says, “‘'There seems to be no method of checking their ravages. The rooks come in great numbers, and they and other birds destroy great quantities.” But the report of the visitation of 1881 in the same forest says, ‘‘ The very rapid and destructive nature of the blight this season may have been caused by the absence of large flocks of rooks, jackdaws, ON BRITISH OAKS. ail starlings, and other small birds, which have in previous years attacked the blight on its first appearance ; and, as each bird will consume a large number of grubs daily, the plague was formerly much checked at the outset. The severe weather of last winter undoubtedly killed large numbers of these birds, and the cater- pillar was consequently almost unmolested.” In this statement it is curious to observe that in the writer’s opinion the severe winter of 1880-81, although it killed the birds, could have had no effect on the insect, and this is another testimony against the theory of a mild winter. Of the five seasons in which the blight was preva- lent, namely, 1831, 1848, 1864, 1881, and 1888, two were preceded by severe winters, namely, 1830 and 1880. As to birds being able to cope with this plague, I have to observe that in 1888 they forsook the woods entirely, and it was even said that the rabbits also did so. No living thing would care to be enveloped in such an annoying network of web. Several species of the large family of Geometrina, or “mea- surers,” so called from their progressing by looping themselves up and then extending their whole length as if measuring, are to be found on the oak, and assist the Z'ortrices in their depredations. The other Z'ortrices besides the Vortrix viridana which infest the oak are— Chloephora Prasinana. Pe Quercana. Lozotenia Sorbiana. Sulvana. es aylosteana (common). Ptycholoma Lecheana (common). Hedya dealbana, Dictyopteryx Leflingiana. Pecilochroma corticana. Ephippiphora argyrana (on the bark), Tortricodes hyemana (very common). Of the Deltowles family only one is found on the oak, namely, Herminia barbalis; and of the Crambites there are three, namely, Acrobasis consociella (not common). Me tumedella (not common), Nephopteryx Roborella (not common). For further information on the subject of Lepidoptera the student is referred to “ Stainton’s Manual.” 32 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. Of the several kinds of larvee which are to be found affecting different parts of the oak tree, I have never found any in the acorn, nor do I find any record of such. This is to be noted, as very few seeds of plants escape the ravages of some variety of insect or another. Fungi. We now come to treat of the fungi that are to be found on the oak, but it is doubtful whether they can be properly classed as a disease, or only as the result of some other disease or of natural decay, for whenever they occur it is a certain sign of the bad condition of the tree. Some tree fungi are not particular as to the tree upon which they grow, whilst others confine themselves to one genus or species. The following may be taken as an approximate list of those found on different parts of the oak, some of which are to be found on other trees and substances :— Galarileus quietus, in oak woods. Pleurotus dryinus, on the tree. ie palmatus, on the tree. Crepidotus aurant ferrugt, on the roots. Coprinarius papyraceus, on the tree. Dedalea quercina, on the tree. Microporus frondosus, on the roots. 3 sulphureus, on the tree. x hispidus, on the tree. Fistulina hepatica, liver-like or beef-steak fungus, grows on old trees in the New, Sherwood, and Epping forests, and is edible. Hydnum minimum, on the rotten timber. erinaceus, hedgehog fungus, is very rare and curious. Found in Epping Forest, and recently in the New Forest, by Dr M. C. Cooke, the eminent myco- logist. Merisma rubiginosa, on old trees. sinuans, on the branches. >? Re quercina, on fallen trees. Helotiwm acicularis, on hollow trees. Bulgaria inquinans, on dead trees. Cenangium quercinam, on dead branches, Kxidia flaccida, on the bark. ON BRITISH OAKS. 393 Stromatospheria parallela, on dead trees. = nivea, on dead branches. 3 quercina, on dead branches. Cryptospheria bifrons, on the dry leaves. Pf punctiformis, on dead leaves. Spheria biphemia, on dead branches. Phacidium coronatum, on dead leaves, m dentatum, on living leaves. Hysterium pulicare, on the rugged bark. a quercinum, on dead branches. Xyloma pexizoideum, on dead leaves, Scleroderma citrinum, on the roots. Erineum griseum, under the leaf. Merulius rufus lachrymans, the dry-rot fungus, is perhaps the most to be dreaded, working in the timbers of buildings silently and unseen with fatal effect. The fungi in their action on the trunks and fallen branches assist in the disintegration and decomposition of the wood, and finally to assimilate it again with the soil. The Lichens which grow on the trunks and branches of most of our trees are an interesting study. They give to them a hoary and venerable appearance when the trees are ’ ** Mossed with age.’ The following are to be found on the oak, but of course there are many more which grow indiscriminately on the trunks and branches of it and other trees :— Spiloma microclonum, on old trees. ” punctatum, on old trees. Lecidea carneola, on old trees. Calicium microcephalum, on oak rails. zs hyperellum, on old trees. Thelotrema melaleucum, on young trees, “= hymenium, on old trees. Beomyces cespititius, on the tree. Ramalina pollinaria, on old trees. Verrucaria analepta, on the bark. Sticta pulmonacea, liver-wort, which, when growing on the oak, is called ‘lungs of oak,” and is supposed then to be specially efficacious in the cure of consumption and other diseases. VOL. XIII. PART I. Cc 34 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. HIsTorRICAL AND REMARKABLE OAKS. | Although other trees have their history and associations, the oak has been the historical tree of Britain, from the dark ages of the Druids until recent times, when it has become less the fashion to plant it as a memorial of the great, or in commemoration of any noteworthy event. How far this latter circumstance is wise, not to say patriotic, is open to question. Is any tree, whether native or foreign, except perhaps the yew, so fitting, in every respect, to tell future ages of what has been done, or to mark the progress of time, as the oak? I trow not. Of oak trees remarkable for their historical associations we have the “Royal,” the “ Parliament,” the “Shire,” the “Gospel,” the “ Cheney Court,” from the French chené, an oak, and the “‘ Bound Tree,” marking the boundary of parishes or manors. In the same manner the name ‘ Gospel” is derived from the ancient custom of treading the boundaries of parishes in “ Rogation Week,” when under an oak tree the Gospel for the day was read, and these trees have generally been preserved, but often under other names. The Notable Oaks of England and Wales. The following list has been compiled from various sources, and from personal observation; but it may here be remarked that some of the measurements given are imperfect or unreliable, the height from the ground where the girth is taken not being given with sufficient accuracy, in many cases, to enable one to compare it with other trees, and a girth at the ground is in most instances valueless when the tree is so buttressed with roots that almost any girth may be arrived at, consequently much room is left for exaggeration. On this point Mr Trowsdale says in the Z7imes, “T would venture to express an opinion that local naturalists and antiquaries would render good service to the cause of literature were they to obtain, by personal measurement, the exact dimensions of the famous old trees now existing in their respective neighbour- hoods.” It is to be understood that in this record of remarkable trees they are all Quercus robur pedunculata, except where it is stated they are Q. 7. sessiliflora. With this preliminary I now proceed with the list. The Cowthorpe Oak, Q. robur pedunculata, whose age has been variously estimated at from fifteen to eighteen centuries, stands ON BRITISH OAKS. 35 in the parish of Cowthorpe, three miles from Wetherby, in the West Riding of the county of York. The circumference of its trunk close to the ground was, at the close of last century, accord- ing to Evelyn’s “Silva,” 78 feet. Shortly after the publication of this work, earth was placed around the base of the trunk, with a view to the preservation of the tree, which by covering over some considerable projections reduced the girth of the stem at the ground line to 60 feet. In 1829 the Rev. Dr Jessop measured the tree, and communicated its dimensions to Strutt’s ‘Silva Britannica,” as follows :— Circumference at ground, : ; : 60 feet. - at 3 feet from ground, . 45 ,, Height of tree, : : 45 ,, Extent of the principal Tine. : : : 50) % Greatest circumference of principal limb, ; oa Dr Jessop adds, “The tree is hollow throughout to the top, and the ground plot inside may possibly find standing-room for forty men.” In Loudon’s “ Arboretum” the diameter of the hollow of the tree close to the ground is given at 9 feet 10 inches. This would give an area of over 96 square feet, which is certainly sufficient to afford standing-room for forty men. In Dr Hunter’s edition of Evelyn’s “ Silva,” the dimensions are given—circumference at the ground, 26 yards (78 feet) ; height, 80 feet ; and its principal limb 16 yards (48 feet) from the bole. This tallies so far with the other account, with the exception of the height of the tree. The “Royal Oak” at Boscobel House in the ancient forest of Brewood, Staffordshire, has become celebrated in history for having given shelter to Charles II. after the battle of Worcester on September 6, 1651. The story is variously told. The Earl of Bradford, in a letter dated Weston Park, May 6, 1878, says, “On one occasion when he (that is, the king) was out with one or two of the Penderils, sounds were heard of horses’ feet not very far off. There was not much time for consideration, but his attendants thought he might not be able to get back to his hiding- place in the house quietly, or perhaps thought that even if he did he might be discovered there, and recommended him to go into a thick part of the wood (being early in September, the trees and underwood were still in full leaf), where they helped him up into an oak tree (not a decayed, but a growing oak tree), and implored 36 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. him on no account to come down from the tree until they returned to him and tell him all was safe. They then went as if to their work or ordinary occupation. The troopers of the Parliament fell in with them, made all sorts of inquiries about the house and its inmates and its neighbourhood, and ultimately rode on without discovering how near they were to the king. The Penderils returned in due time, and conducted the king back to the house.” The tree stands in a field near the garden of Boscobel house, and is surrounded by an iron palisading. It has a circumference, at 4 feet up, of 12 feet 3 inches. That the tree now standing is the same in which the king was concealed has been questioned, and that it is only a seedling from the ‘“ Royal,” some authorities alleging that it is only 160 or 170 years of age, whilst others put it between 400 and 500. On this point it may be as well to quote again Lord Bradford’s letter, and to mention that his seat of Weston Park adjoins Boscobel: he says, ‘‘ The tree was from that time well known to them (that is, the Penderils), and doubtless to the owner, Mr Giffard, and other loyal friends in the immediate neighbourhood ; and after the Restoration, which was only nine years afterwards, probably numbers of people visited the tree, although at that time in a thick coppice with only woodmens’ paths or very bad cut roads in the neighbourhood. The coppice was subsequently cleared, I apprehend, in the time of the Fitz- herberts, who inherited from the Giffards, but the tree into which the king climbed was left standing and regarded with pride and affection. It has been known from father to son by succeeding generations from that time to this. As to its being a substitute of any sort, least of all an acorn from the original tree, I discard the idea as ludicrous and absurd. J have known the tree myself for half a century.! It looks now very much as it did then ; and nearly as long ago as that I remember my father speaking of the absurdity of the stories then current as to the owl flying ont of the decayed tree, the present tree being an acorn from the old one, and such like. He used to say that he had heard his father, and, I think, his grandfather, speak in the same sense ; and the recollection of the tree by his grandfather (my great-grandfather) would easily carry him back as far as 1740, which would be less than ninety years after the king sat in the tree.” ' Karl Bradford was born in 1819. ON BRITISH OAKS. Biff “T may mention, with respect to oak trees and oak wood in this neighbourhood, that there are trees still alive in this park estimated to be 1100 or 1200 years old ; there are others reckoned to be 600, 500, and 400 years old. Sometimes a smaller tree is known to be considerably older than a larger one, and I should myself estimate the tree at Boscobel to be 400 or 450 years old ; but it would have been equally capable of affording a hiding-place for a man in the middle of a thick wood, whether it was then some 220 years old, as I estimate it, or whether it was 100 years younger or older.” Against this evidence as to its being the original ‘‘ Royal” oak, another witness says “that he measured it in 1857, and again twenty-one years later, and found that its girth had increased 11 inches, or half an inch annually.” In summing up the evidence for and against, it is necessary to bear in mind that the original tree was in a thick wood, and not a detached tree, or in any way conspicuous, which would have been sure to attract the attention of the Parliamentary troopers. Further, this wood seems to have subsequently been cleared by the Fitzherberts, the successors of the Giffards, but at what date is not stated. Now this fact would have gone far to establish the identity of the tree or otherwise, because, if the date of clearing or grubbing up of the wood was not long after the event, then it would be probable that the Fitzherberts knew the real tree, as they surrounded a@ tree by a brick wall; but if this took place very long after, then a doubt would still remain notwithstanding Lord Bradford’s testimony, as the tree is certainly of small girth for say 450 years. The “ Parliament Oak” in Clipstone Park, Notts, is so called from an informal parliament having been held under it by King John, in 1212. Bailey says, ‘‘ John this year perpetrated the enormous cruelty of putting to death, by hanging, at Notting- ham Castle, twenty-eight youths belonging to the most illustrious families of Wales, which youths he had brought with him after the rebellion as hostages for the future peace and submission of the principality. At the time this event took place, the king was indulging himself in the pleasures of the chase at Clipstone Palace, -when a messenger arrived from his sister Joan, who was married to Llewellyn, Prince of Wales, informing him of a fresh revolt, and at the same time another came with a letter from his friend and ally, David L., king of Scotland, apprising him of the exist- ence of a widespread conspiracy against him in the northern parts 38 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. of the kingdom. Hastily summoning a council of the barons and other distinguished individuals who were about his person or in the immediate vicinity of the palace, they met under the boughs of an oak tree in the park, which thence obtained the appellation of the “Parliament Oak.” Another parliament is said to have been held here in 1290 by Edward I. This tree stands in a nook by the side of the highway leading from Edwinstowe to Mansfield, at a point where that road is intersected by a private way of the Duke of Portland’s. It has a circumference at 3 feet up of 28 feet 6 inches, but it is only a living ruin. The ‘‘ Greendale Oak” is, however, the most remarkable of the Welbeck oaks. It stands about half a mile south of the abbey, and is computed to be one of the oldest trees in existence in this country. The trunk having a century or two back become quite hollow with age, and so much decayed that large apertures occurred in its sides, the opening was, in 1724, sufficiently enlarged by cutting away the decayed wood, to allow an ordinary carriage to pass through, and it is said that one of its noble owners was actually driven through this opening with his bride, on the occasion of his marriage, in a carriage drawn by six horses. The height of the opening is 10 feet 3 inches, the width 6 feet 3 inches, and the circumference at the ground is 36 feet, above the arch 35 feet 3 inches, and the sheer height 54 feet.! The “Shambles Oak” is another remarkable Welbeck tree. It is traditionally said that in its hollow trunk Robin Hood and his merry men used to hang up their venison as they would in a butcher’s shop, until wanted, and that near it much of their cooking was done and revels kept. Some of the iron hooks are said still to be seen in the interior. It is said that, in later times, this notable tree was used by a sheep-stealer as a place wherein to hang his ill-gotten spoil until he could safely dispose of it. From these circumstances the tree acquired its name of the “Shambles Oak.” The ‘‘Two Porters,” a pair of grand old trees, so called from 1 The dimensions of this famous tree, accurately measured for the Royal Scottish Arboricultural Society by Mr Jameson, forester on the Welbeck estates, on the occasion of the Society’s visit to it on the 7th August 1889, are as follows :—height, 45 feet; girth, 31 feet at the base, and 30 feet at 5 feet up; the opening in the tree, 9 feet 1 inch high, by 7 feet 3 inches wide on the east, and 5 feet 4 inches on the west side.—Ep. ON BRITISH OAKS. 39 there having been once a gate between them. They stand nearly at the north extremity of the park, not far from the south lodge of Worksop Manor, and the drive passes between them. They measure as follows :—circumference at the bottom, 38 feet; at 3 feet up, 27 feet ; and at 6 feet up, 23 feet ; sheer height, 98 feet 6 inches. The other has a circumference at the bottom of 34 feet; at 3 feet up, 23 feet; and at 6 feet up, 20 feet; sheer height, 88 feet. These oaks are Quercus robur sessiliflora.+ The “Seven Sisters” so called from having consisted originally of seven stems springing from one common root, is one of the most remarkable trees anywhere in existence. Some of the “sister” stems have, from time to time, been blown down, but it is still a noble tree. It is situated about half a mile from the “Two Porters.” The circumference of the common trunk, close to the ground, is over 30 feet, and the height 88 feet. The measurements of the ‘‘Seven Sisters” were given nearly a century ago, as follows :—in height it is 88 feet 7 inches; the circum- ference at the bottom is 30 feet; at two yards, taking in the stems, 30 feet 4 inches. The largest stem at two yards is 12 feet 10 inches in circumference ; another at the same distance from its bottom is 11 feet 7 inches; one, 9 feet 10 inches; and the smallest, 5 feet 3 inches in circumference.? The ‘Queen Oak,” now called the “ Major Oak,” so named, it is said, after Major Hayman Rooke, who often visited it, and wrote much on the forest; it was also called the ‘ Cock-pen Tree,” from its hollow interior being occupied as a hen-roost. The hollow is nearly 7 feet in diameter and 15 feet high. A considerable portion of its tendons appear above ground, and measuring these about halfway between their junction with the trunk and their insertion in the earth, they gave a circumference of nearly 30 yards; the circumference of the trunk at nearly 6 feet from the ground, the height at which begin the branches, 1 On the occasion of the Society’s visit in 1889, the ‘‘ Two Porters” were measured, and the dimensions are given in the Report of the Excursion as follows:—No. 1 girths at base 36 feet 8 inches, and at 5 feet up 25 feet 8 inches; and is about 24 feet high, having been broken off by a storm in 1881. No. 2 girths at base 36 feet, and at 5 feet up 23 feet 2 inches; and stands about 60 feet high.—Ep. 2 The last of the ‘‘Seven Sisters’ was blown down about a year previous to the Society’s visit on the 7th August 1889, so that this famous tree is now a thing of the past.—Ep. 40 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. was 30 feet, at 4 feet the circumference is 29 feet, and the sheer height 80 feet.? The “ Ruysdael Oak,” so named by a late Duke of Portland, because it resembled in shape those peculiarly formed trees which that great painter delighted to introduce in his pictures. It stands on a commanding eminence in the park, not far from the ‘Seven Sisters,’ and forms a striking object from whichever side it is seen, notably from the mansion itself.” The ‘Simon Forester” oak is another of the famous trees in Sherwood Forest, with a circumference of 22 feet and a height of from 50 to 60 feet. Such are some of the notable old trees of ‘‘Sherwood Forest” which have received names, but although now no longer a royal forest, there still exist many other grand old oaks that date back to times when this great forest was the hunting-ground of kings. We now come to the oaks in Windsor Park. . The “Cow Pond Oak” may be first noticed, as it is one of the few trees of which we can fix the date of planting with any accuracy. ‘The account is, ‘‘ About the year 1715 the plantation lying between Cumberland Lodge and Cow Pond was formed, and we mention it simply because it contains what is generally considered to be the most perfect timber tree in Windsor Park. It has a straight clean bole over 40 feet up to the first branch, with a girth of 10 feet 4 inches at 5 feet from the ground ; now, taking the age up to 1880, would be 162 years, this would give an annual increase in circumference of *765 inch. “ Herne’s Oak.” This tree or trees, for it appears there were two claiming the honour of being the tree immortalised by Shakespeare in the ‘ Merry Wives of Windsor ”— ‘« There is an old tale goes, that Herne the Hunter ; Sometime a keeper here in Windsor Forest, Doth all the winter-time, at still midnight, Walk round about an oak, with great rage’d horns ; And there he blasts the trees, and takes the cattle, And makes milch kine yield blood, and shakes a chain In a most hideous and dreadful manner.” ‘In the Report of the Society’s Excursion in 1889, the dimensions of the “Major Oak” are given as—girth, 29 feet 6 inches at 5 feet up; height, 60 to 70 feet ; spread of branches, 90 feet. ***Gaunt and dead at least fifteen years, but it still defies the blast and maintains an upright position’ (Report of Society’s Excursion, 1889).—Ep. ON BRITISH OAKS. 4] Some years ago a sharp controversy was carried on as to the identity of “ Herne’s Oak,” it being contended by some authorities that it was cut down in error, during the reign of George III., about the year 1796; the other “* Herne’s Oak” was blown down in 1863, but as the Queen has planted one in its place, this will perpetuate the name. It stood in the Home Park, but I cannot find what were its dimensions. “Queen Elizabeth’s Tree,” so called from having been said to have been a great favourite of the virgin Queen. It stands close to the site of ‘‘ Herne’s Oak.” “‘Shakespeare’s Oak,” another tree supposed to have been the great poet’s favourite oak, stands close by the last ; both are said to be fine trees, but in neither case have we got dimensions. ‘William the Conqueror’s Oak.” Beyond the fact that this tree has been associated with the Norman’s name from time immemorial, its history is unknown. The main stem has long been decayed, and is supported with props. It is situate near Cranbourne Lodge, just within the park palings, and is, con- sequently, but little seen by the public. It has a circumference of 37 feet at 5 feet up. The ‘‘ Forest Gate Oak” is an old pollard, with a circumference of 28 feet 4 inches. “Queen Anne’s Oak” has a circumference of 15 feet 3 inches at 5 feet up, and is 60 feet high. “Queen Charlotte’s Oak” has a circumference of 17 feet 3 inches at 5 feet up, and is 65 feet high. “Queen Victoria’s Oak ” is perhaps as handsome a specimen of a thriving young oak as it would be possible to find. It has a magnificent straight stem 38 feet up to the first branch, and a beautifully rounded head. It was chosen by Her Majesty as her favourite oak soon after her accession. It is 11 feet 11 inches in circumference at 5 feet up, and is 70 feet high. The three last-mentioned ‘‘Queen” oaks are in the forest between Highstanding Hill and New Lodge. The ‘“ Prince Consort's Memorial Oak,” planted by Her Majesty on November 25, 1862, marks the spot where her much-loved husband finished his last day’s shooting on November 23, 1861. Before taking leave of Windsor, it may be as well to notice the plantation, containing a large group of oaks, stretching from the back of the park bailiffs house in the direction of Cranbourne Walk. It is supposed that allusion is made to this plantation of 42 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 14 acres in a document of the year 1625, which had been fenced with pales into the Great Park, and sown with acorns in 1580. These trees, at the present time, are of a singularly uniform character, and perfectly healthy. This is supposed to be the earliest authenticated record of any regular plantation known to have been made in England. They number about twenty-one to the acre, and their average content is about 88 feet. In addition to this, it would be desirable to have more details as to the size of individual trees, as this would be a contribution towards solving the question of ‘raising forests from seed.” The ‘* New Forest” in Hampshire, although of large extent, has few oak trees of interest. They do not grow so high or so large as in many other parts of England, but they are more picturesque in their outlines, appearing in the distance as if suspended in the air rather than growing out of the earth. The “ Western Oak” at Boldrewood has a circumference of 24 feet 9 inches. The ‘‘ Eastern Oak,” at the same place, has a circumference of 16 feet. The “ Northern Oak,” also at Boldrewood, has-a circumference at the thickest part of 20 feet 4 inches; lower down it is only 14 feet 8 inches. The “ Knyghtwood Oak” has a circumference of 17 feet 4 inches. The “ Moyle’s Court Oak” is a handsome tree, standing a few yards outside the “ Forest” boundary. It has a circumference of 18 feet 84 inches. The ‘Cadnam Oak” is remarkable in that it puts forth young leaves on Old Christmas morning, which fact seems to be well attested. A description of this tree appeared in Woods and Forests, February 1885, the writer of which, after a graphic account of his visit to it on Old Christmas morning in that year, says, ‘‘ perhaps some of your correspondents may know of such in other parts of England ;” but to this there was no response, so it may be presumed that this oak is unique. It stands some 10 yards to the north of the Southampton Road, where that to Ringwood crosses it, by the fence of Widow Gain’s garden, and has a circum- ference of 10 feet 6 inches at 4} feet up, a bole of 17 feet, and a height of 55 feet. It is apparently a young tree, although a good part of the south side of the whole length of the trunk is gone, which is, however, being fast covered over by the growth of the tree, although it is still from 1 foot to 18 inches broad. ON BRITISH OAKS. 43 “Oakley Oak” is situated in a meadow to the east of Oakley farm-house, from which it is separated by a branch of the river Test, leading to the grounds of Mottisfont Abbey in Hampshire. It has a circumference of 31 feet 6 inches at 44 feet up; at 9 feet it branches into six large but hollow limbs, where, owing to the swell of its branches, the circumference is much larger; the sheer height is 27 feet. The living branches are comparatively young, and they put forth leaves and bear acorns freely. The trunk is quite hollow, and has a cavity measuring at the ground 9 feet by 9 feet in diameter, and at 44 feet up 7 feet by 7 feet, which is the smallest diameter of the hollow trunk. The entrance to the interior is on the north side, and is 3 feet 7 inches high, and 1 foot 8 inches wide. The hollow limbs admit plenty of light into the interior. “Seven Yards Oak.” This is an old tree, showing signs of decay, and although apparently sound in the trunk, it does not look so healthy as the “ Oakley Oak.” It stands in Hurstbourne Park, belonging to Lord Portsmouth, near Whitchurch in Hamp- shire, and on the boundary between the parishes of Hurstbourne Priors and Whitchurch. It is not known how long it has borne the name of “Seven Yards,” but 21 feet is still the circumference at 44 feet up. , “Canon Beadon’s Oak.” I notice this tree because its history is given as follows :—‘ This oak was planted by the late Canon Beadon in North Stoneham Rectory grounds, near Southampton, when home from school, at the age of fourteen years, the same having been raised from an acorn in a flower-pot by his sister. The Rey. Canon died June 10, 1879, having lived to sit under this oak, now a considerable tree, and witnessed a cricket match when he had attained his one hundredth year, the tree being then eighty-six years of age. The circumference is 11 feet 5 inches at 4} feet up. “Dean Forest” is another Royal Forest, and although not so large as the “New Forest,” is not without some notable trees, viz. ,— “Jack of the Yat,” which is probably the oldest within the present bounds of the “ Forest,” stands by the roadside near the 16th milestone on the Long Hill. In 1830, it measured 17 feet 83 inches at 6 feet up; in 1846, 18 feet 34 inches; but in 1881, it was only 18 feet + inch. This discrepancy can hardly he accounted for. 44 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. The “ Crad Oak” is a fine specimen of Quercus r. sessiliflora, in flourishing condition. It stands back in the woods behind “ Jack.” That is all the information we have respecting this “fine speci- men,” but it is certainly desirable that something should be known of its dimensions, as so few trees of this species of oak are recorded. The ‘“‘ Newland Oak” stands outside the present Dean Forest, but within the ancient forest bounds, and is a large old tree, measuring 41 feet round the trunk, and being probably one of the oldest and largest oaks in the kingdom. Another account says, *Tts trunk is not buttressed at the base, and the girth of 52 feet at the ground is scarcely lessened up to 12 feet, where five grand primary branches spread out from the hollow bole, divaricating into more than fifteen. The ‘‘Colwall Oaks.” In the parish of Colwall, near the old hunting-seat of the bishops of Hereford, is a good-sized fish-pool, and near this pool, in the middle of a pasture, stand these trees, supposed to be the two oldest oaks anywhere about the Malvern Hills, showing undoubted evidences of very great antiquity. The largest has been much shattered and lost some of its finest branches, so that at a distance it has a lank and attenuated look. The extreme base of the trunk bulges out considerably, and is more than 60 feet in circumference; but this diminishes so quickly that at a yard from the ground it girths only 27 feet. The companion oak to the great one, and almost as old, girths 45 feet round the swollen base. The “Old Pollard Oak.” In the southern part of Malvern Chace, in a field near the Severn, stands this tree, putting out horizontal arms in a very curious manner. It is a characteristic specimen of what is called a “burr oak,” of which many may be seen in the neighbourhood, the result of pollarding from time to time. The circumference at 3 feet up is 17 feet. The “Devil’s Oak.” This tree has assumed a demoniacal shape, the result also of pollarding, and presents a most grotesque appearance. It is said, however, that the appellation was really given to it from some sweeps having been seen to emerge in the mist of an autumnal morning from its cavity, where they had been sheltering, and as they disappeared in the fog, were very like imps of the evil one. The name, at all events, is likely to stick to the deformed tree. It stands in a hedge by the side of the road leading to Sherrard’s Green, below Great Malvern. ON BRITISH OAKS. 45 The “Cowleigh Oak” is the most conspicuous tree in Malvern Chace for size and spread of bough. It is called ‘“ Cowley’s Oke” in a MS. Survey of Malvern Chace, a.p, 1633, and stands near Great Malvern, in the middle of a pasture next to Cowleigh farm- house. It has a circumference of 27 feet at 3 feet up. The “Great Burr Oak” is another remarkable tree, the result of pollarding, and which has hardly any trunk. It stands on the banks of the Teme in the parish of Leigh, about a mile west of Bransford Bridge, and has a circumference of 20 feet at 3 feet up. The ‘Gibbet Oak’ is supposed to derive its name from having been used as the place for hanging spies and traitors in the Wars or the Roses. It stands on a gentle eminence at short distance from the Tenbury and Bromyard main road in Kyre Park, Worcestershire. It measures 24 feet in girth at 5 feet up, and its huge and widely-extended arms, standing out at right angles some 8 feet or 9 feet from the ground, seem to be well adapted for the use then made of it. The “Weeping Oak” at Moccas Court, Herefordshire, was considered by Loudon to be one of the most remarkable oaks in England. ‘The branches reach from about the middle of a trunk of 75 feet to within 7 feet of the ground, hanging down like cords, and many to a length of 30 feet, having a thickness which does not in any part of them exceed that of a common waggon rope. The entire head covers a space of 100 feet in diameter. The “ Weeping Oak” at King’s Acre, Hereford, was planted in 1785 by a Mr Cranston, and grafted at about 3 feet from the ground. The girth of the trunk at 4 feet up is 8 feet 6 inches; height to the lowest branch, 18 feet; spread of branches, 58 feet ; and the sheer height, 72 feet. The “Coronation Oak,” so called from the proclamation being announced therefrom on a king or queen being crowned, The coronation of Queen Victoria was announced from under the spreading boughs of this grand old tree. It stands in one of the meadows on the farm of Llanhenosk, near Caerleon, Monmouth. The circumference of the trunk in its largest part is 38 feet 6 inches ; in the middle, 32 feet 1} inches ; and the smallest, 27 feet 6 inches: the bole is 15 feet in height. The “Pencraig Oak” is on Pencraig Farm near Newport, Monmouth. It has a circumference of 38 feet; height to first branch, 15 feet, with a spread of branches of 36 yards, 46 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. The ‘Cressage Oak,” or “Christ's Oak,” under which it is said the early Christian missionaries, and possibly St Chad him- self, preached to the heathen before churches had been built, is the sole remaining tree of those vast forests which gave Shrews- bury its Saxon name of Schobbesburgh. It stands in an arable field on the banks of the Severn, half a mile from Cressage in Shropshire. It has a circumference of about 30 feet at 5 feet up, although only about one-half of the shell of the hollow trunk now remains, but it has still fifteen living branches, each 15 feet or 16 feet in length. The “ Beggar’s Oak” grows in Lord Bagot’s park, m North Staffordshire, and is said to be one of the most picturesque trees in England. The head is round and full of foliage, drooping almost to the height of a stag, and offerimg a welcome shelter either in the heat of a summer day or during a storm. The circumference above the swell of the spurs is 27 feet 3 inches, and at 5 feet the girth is 23 feet 2 inches ; the branches extend from the trunk 50 feet in every direction, and the height is 60 feet. The ‘Squitch Oak” is also in Lord Bagot’s park, has a cireum- ference of 23 feet 2 inches at 5 feet from the ground. The ‘‘ King Tree” is another noted tree in Lord Bagot’s park. It was considered when sound to be the most valuable oak in the park, which is celebrated for its numerous splendid oak trees, and was valued in 1812 at £293. It has a circuinference at 5 feet up of 20 feet, and runs up without a limb to 30 feet, with a sheer height of 70 feet. The “ Venison Tree” is supposed to be the oldest tree in Bagot’s Park, and in existing records is shown to have been a tree of note upwards of six hundred years ago. The ‘White Tree,” in the same park, so called from its varie- gated leaves, which are blotched with white, has a very remark- able appearance in contrast with the dark green foliage of its neighbours. The “ Swilcar Lawn Oak” grows in Needwood Forest, Stafford- shire, and towers above all others. It has been poetically named the forest’s “chief mourner.” It has a circumference of 27 feet at 5 feet up. The “Oaks of Caulke Abbey,” Derbyshire. No. 1 girths 25 feet 3 inches above the swell of the roots, and is 75 feet high. No. 2 is a fine tree, girthing 18 feet at 1 foot up, and is 60 feet high. No.3 girths 20 feet at 1 foot up, and has scarcely any ON BRITISH OAKS. 47 taper for a height of 30 feet, is in vigorous health, and a fine timber tree. No. 4 is in a glen near the Monk’s Cave. It girths at the top of the trunk, which is 12 feet long, 28 feet, and at the bottom 31 feet. The ‘ Queen’s Oak” grows at Grafton, Northamptonshire. Sir John Grey of Groby, who fell at the battle of St Albans, being a zealous Lancastrian, his estates were forfeited by the victorious Edward, and under this oak, according to tradition, his widow first met Edward IV., whom she had sought to implore the resti- tution of her slain husband’s forfeited estates. Edward was captivated with her person and manners, and finding her virtue inflexible, was married to her, though the marriage was not proclaimed till some months afterwards. This lady’s name was HKlizabeth Wideville, daughter of Richard, Earl Rivers, and the first British lady subsequent to the Norman Conquest who shared the throne of her sovereign, The hollow trunk has a circumfer- ence of 22 feet at 5 feet up. The ‘‘ Yardley” or “ Cowper’s Oak,” also called “ Judith,” from an old legend that it had been planted by the Conqueror’s niece Judith, Countess of Northumberland, who held eighty-eight manors in Northamptonshire, including a portion of Yardley. On the tree is fastened this warning—‘“ Out of respect to the memory of the poet Cowper. The Marquis of Northampton is particularly desirous of preserving this oak. Notice is hereby given that any person defacing or otherwise injuring it will be prosecuted accord- ing to law.” The tree is a ruin, with a hollow trunk broken through below, and capable of holding many persons. There are two or three bare limbs, from which the bark has fallen, showing like whitened skeletons against the lichened and knotted rind of the trunk, and there are at least two large boughs which still send out their clusters of green leaves. The circumference is 30 feet 6 inches at 1 foot up, and 30 feet at 3 feet up. The ‘ Bull Oak,” in Wedgenock Park, Warwick, was a remark- able tree, now only a ruin, with a butt 18 feet in diameter at the ground. Growing from among its roots is a beautiful ash tree. In Stoneleigh Park, Warwick, near the Abbey, there are many fine oaks. One has a circumference of 24 feet, and is a perfect model of an oak. Another in the Deer Park has a circumference of 36 feet 9 inches. “ King Charles’ Oak,” in Blenheim Park, Oxfordshire, is a very 48 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. fine tree, with a circumference of 23 feet, a bole of 23 feet, and contains 765 feet of timber. The two “ Ampthill Oaks” grow in Ampthill Park, Bedford- shire. This park extends over the sides and summit of the rising ground, and its sweeping glades and hollows, with much wood of later growth, display a greater number of venerable oak trees than, perhaps, any other park in England of the same extent. On one of the two trees the following verses are fastened :— ** Majestic tree, whose wrinkled form has stood, Age after age, the patriarch of the wood ; Thou who hast seen a thousand springs unfold ‘Their ravelled buds, and dip their flowers in gold, Ten thousand times yon moon relight her horn, And that bright star of evening gild the morn. Gigantic oak ! thy hoary head sublime, Erewhile must perish in the wreck of time. Should round thy head innoxious lightnings shoot, And no fierce whirlwind shake thy steadfast root ; Yet shalt thou fall, thy leafy tresses fade, And those bare scattered antlers strew the glade. Arm after arm shall leave the mouldering bust, And thy firm fibres crumble into dust. The muse alone shall consecrate thy name, And by her powerful art prolong thy fame, Green shall thy leaves expand, thy branches play, And bloom for ever in the immortal lay.”’ This provoked the following retort from Lord Wensleydale :— ** Tl] bet a thousand pounds—and time will show it— That this stout tree survives the feeble poet.” The two trees stand at a short distance from the mansion, and are nearly of the same girth, namely, a little over 35 feet at 3 feet up. “Queen Elizabeth’s Oak” stands in Hatfield Park, Hertford- shire. ‘On the morning or afternoon of November 17, 1558, for Mary died between 4 and 5 a.m., Elizabeth was sitting under this tree, when a deputation arrived from the council to apprise her of her sister’s demise and to offer her their homage. She fell on her knees, and exclaimed in Latin, Domino factum est illud, et est mirabile inoculis nostris, ‘\t is the Lord’s doing, and it is marvellous in our eyes.’” It stands half-way down the avenue leading from the house towards Hertford. It is surrounded by a fence, and is not in vigorous health, or of a very remarkable bulk. We have no measurements of this historical tree. ON BRITISH OAKS. 49 The “Lion Oak” stands also in Hatfield Park, and has a circumference of 32 feet. The “Grimston Oak” was planted by James, second Viscount Grimston, who died in 1773. The tradition is that Lord Verulam’s great grandfather planted this tree with his own hands some twenty years before his death, so that it would now be over one hundred and thirty years. It stands a few yards from Oxhey Chapel, about 2 miles from Watford, Hertfordshire, and has a circumference of 17 feet and a bole of 24 feet. Two “Pollard Oaks,” in Moor Park, Hertfordshire, girthing 23 feet and 25 feet respectively ; said to have been pollarded or beheaded in 1686 by the Duchess of Monmouth in revenge for the execution of her husband. The “ Winfarthing Oaks” stand in the parish of Winfarthing, Norfolk. No. 1 has been long known as the ‘“‘ Winfarthing Oak.” Robert Marsham measured this tree in 1744, and gives the circum- ference as 38 feet 7 inches. Mr Geo. Southwell measured it in 1874, when it had a circumference of 40 feet, giving an increase of 17 inches in 130 years. No. 2 was measured in the same years by the same gentlemen, and had a circumference in 1744 of 30 feet, and in 1874 still only 30 feet, having remained in statu quo. “ Wilberforce’s Oak,” at Holwood, Kent, so called from the great philanthropist who brought about the abolition of slavery. The following words, from his diary of the year 1788, are engraved on a stone chair which Earl Stanhope set up close to this historic tree in 1862; they are, “At length I well remember, after a conversation with Mr Pitt in the open air at the root of an old tree at Holwood, just above the steep descent into the vale of Keston, I resolved to give notice on a fit occasion in the House of Commons of my intention to bring forward the abolition of the slave trade.” This tree has a circumference of 18 feet 1 inch at 3 feet up, and 18 feet 3 inches at 5 feet up. “Pitt's Oak,” at the same place, perpetuates the name of the great statesman. He used to sit and read underneath its spread- ing branches. It stands near Holwood House, and has a circumference of 20 feet 1 inch at 3 feet up, at 8 feet up it divides into four massive limbs and spreads its branches 57 feet, the sheer height being only 36 feet. The “Two Oaks” in Cowdray Park, Sussex. No. 1 was measured in 1819, and had a girth of 20 feet at 1 foot up, which was increased to 28 feet in 1879; at the same date it had a girth VOL, XIII, PART I. D 50 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. of 19 feet at 5 feet up; sheer height about 80 feet. No. 2 hada circumference in 1879 of 19 feet 2 inches at 5 feet up, and a sheer height of 90 feet. “Miss Maury’s Oak” has been long spoken of as an object of interest, especially on account of the loving care and the value attached to it by its aged owner. It is not a large nor a very old tree, but is remarkable for its symmetrical proportions and finely- developed head. It stands in a paddock in front of the old farm- house in the parish of West Wellow, Wiltshire, and has a circum- ference of 16 feet 9} inches at 4} feet up; a bole of 9 feet to where ten large boughs had sprung from the parent stem, now only five, some of them 2 feet in diameter; the sheer height is 90 feet, and it spreads its branches from east to west 36 yards, and from north to south 33 yards. “No Man’s Oak,” or the ‘ Forest Tree,” is a striking object, standing on an elevated ridge at the northern boundary of the New Forest. Its knotted and gnarled trunk and bare arms, but scantily clothed with ivy, give it a weird-like appearance, as it stands alone without a companion living or dead. It is, however, quite dead, but is to all appearance sound timber, and it is difficult to account for its death. The place is named “No Man’s Land,” and here the counties of Hants and Wilts are divided by a bank and ditch which are wholly in Wilts, and on the bank stands the tree, about 4 feet within the county. It has a circumference of 10 feet 6 inches, and a bole of 10 feet. The “ Longleat Oak,” at the Marquis of Bath’s Wiltshire seat, has a circumference of 25 feet 6 inches at 5 feet up. ‘Penrhyn Castle Oaks,” Caernarvonshire, of which there are two to be noticed, are standing near the castle. No. 1 girths 10 feet 1 inch at 3 feet up, with a length of bole of 50 feet. No. 2 girths 10 feet 10 inches at 3 feet up, 9 feet 7 inches at 5 feet up, with a length of bole of 43 feet. Although tradition reports some large ere which were in existence in ages past, both in England and Wales, the accounts relating to them are no doubt in many cases considerably exag- gerated ; still the measurement of some of them are sufficiently authenticated to warrant the conclusion that there are none at present in existence so large as some of the giants of old, as for example, the “Golynos Oak,” which grew about four miles from the town of Newport in Monmouthshire, which was felled in the year 1810 for the use of His Majesty’s navy, and contained the ON BRITISH OAKS. ill large quantity of 2426 cubic feet of sound convertible timber. It was bought standing for £405, and the whole produce of the tree, when brought to market, was within a trifle of £600. Now, no tree 1s in existence which approaches this in size and soundness, and I have given an account of it because the particulars are well authenticated. The Notable Oaks of Scotland. Scotland cannot boast of such giant oaks as are found in England and Wales, but there are many remarkable old oak trees scattered over the northern country; and the following description of some of the more notable is taken from “ Forestry,” the Transactions and Reports of Excursions of the Royal Scottish Arboricultural Society, Hunter’s “Woods and Forests of Perth- shire,” and various other publications. The “ Wallace Oaks,” for there are two associated with the name of Scotland’s great patriot. The one at Torwood, Stirlingshire, had a girth of 22 feetin 1771. The other one is at Elderslie, Renfrewshire, the birthplace of Wallace. It has a girth of 21 feet at the ground, 13 feet 2 inches at 5 feet up; height, 67 feet ; and its branches extend 45 feet east, 36 feet west, 30 feet south, and 25 feet north. Wallace and three hundred of his men hid themselves from the English among the branches of this tree, which was then in full leaf. It is said to cover 19 poles of ground, but, according to the above measurements, it would not appear to cover quite 13 poles, taking it as a circle, and even taking the space covered as a square, would only be over 16 poles. Of the “Inveraray Oaks,” one is growing in the grounds of Inveraray Castle, Argyllshire, and has a girth of 12 feet 11 inches at 5 feet up, a straight clean bole of 20 feet, and a height of 96 feet. No. 2,is at the Dhu Loch avenue, and girths 12 feet at 5 feet up. No. 3, at the same place, girths 11 feet 7 inches at 5 feet up. No. 4 is close by the Aray stream, with a girth of 12 feet 4 inches at 5 feet up. No. 5 is on a sloping bank at Maam, and girths 12 feet 2 inches at 5 feet up, and attains a height of 50 feet. On the north side of Loch Arkaig, in Lochaber, Inverness-shire, there is an oak with a circumference of 27 feet 6 inches at 4 feet up. The ‘ Darnaway Forest Oaks,” Morayshire. No. 1 is on a 52. TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. rising ground forming the centre of a little clearing. It girths 11 feet 6 inches at 1 foot up, 9 feet 3 inches at 5 feet, a bole of 15 feet, and a spread of branches of 80 feet. No. 2 is in the Haugh of Logie, with a girth of 13 feet 9 inches at 1 foot up, 11 feet 5 inches at 5 feet, a clean bole of 23 feet, and a spread of branches of 75 feet. The following are also situate in the “Haugh,” and, according to Sir Thos, Dick Lauder, this grove, previous to the great flood in August 1829, when many of the trees growing nearest the river were washed away, contained the finest oaks in Scotland. No. 3 has an irregular gnarled stem, gurthing 23 feet at 1 foot up. No. 4 girths 27 feet 9 inches at 1 foot up, and 20 feet 5 inches at 5 feet up. No. 5 girths 20 feet 6 inches; No. 6, 20 feet 5 inches; No. 7, 18 feet 8 inches; No. 8, 17 feet 1 inch ; No. 9, 16 feet ; No. 10, 14 feet—all at 5 feet up. An oak on the banks of the romantic Findhorn, on the Altyre estate, Morayshire, has a circumference of 16 feet 7 inches at 1 foot up, 13 feet 3 inches at 5 feet up, and spreads its branches 100 feet. The “ Drummond Castle Oaks,” Perthshire. No. 1 grows by the side of the burn to the east of the castle—it girths 19 feet 6 inches at 1 foot up, 14 feet 8 inches at 5 feet up; length of bole, 12 feet; a height of 70 feet; and a spread of branches of 114 feet. No. 2 adjoins the last, and girths 13 feet 4 inches at 1 foot up, 10 feet 1 inch at 5 feet up; length of bole, 14 feet ; height, 81 feet; and spreads its branches 77 feet. No. 3 also adjoins, and has a girth of 10 feet 10 inches at 1 foct up, swelling out to 15 feet 8 inches at 5 feet up; length of bole, 11 feet; and the height, 45 feet. There are two fine oaks at the south end of the loch. No. 4 girths 18 feet 7 inches at 1 foot up, 11 feet 10 inches at 5 feet up; length of bole, 21 feet 6 inches; height, 78 feet 6 inches; and a spread of branches of 100 feet. No. 5 girths 14 feet 3 inches at 1 foot up, 11 feet at 5 feet up; length of bole, 17 feet ; height, 64 feet ; and spreads its branches 73 feet. No. 6 grows by the side of the walk circling round the south side of the gardens—it girths 14 feet 4 inches at 1 foot up, 10 feet 9 inches at 5 feet up; length of bole, 26 feet; and a height of 96 feet. No. 7 is a gnarled old tree by the side of the burn east of the castle—it girths 17 feet 4 inches at 1 foot up, 17 feet 7 inches at 5 feet up; length of bole, 9 feet; and a height of 66 feet. The “‘ Lawers Oaks,” of which there are two, near the ruins of ON BRITISH OAKS. 53 the chapel at Lawers, near Comrie, Perthshire. No. 1 girths 20 feet 8 inches at 1 foot up, and 13 feet 5 inches at 5 feet up. No, 2 girths 20 feet 7 inches at 1 foot up, and 12 feet 6 inches at 5 feet up. The ‘‘ Ochtertyre Oaks,” at Ochtertyre, near Crieff, Perthshire, ‘« By Ochtertyre there grows the aik.” In a group by the margin of the loch is an oak girthing IS feet 1 inch at 1 foot, 16 feet 2 inches at 5 feet up, with a length of bole of 12 feet. “« Hppie Callum’s Oak” stands at the corner of the road leading to Messrs Morgan’s saw-mills at Crieff. It is said to have been raised in a tea-pot by ‘‘ Eppie,” and then planted out. It has a girth of 16 feet at 3 feet up, and is a grand tree. The ‘‘Pepperwell Oak” grows near Methven Castle, Perth- shire, so called from being near a well of that name. It girths 23 feet at 1 foot up, 19 feet 6 inches at 5 feet up, a height of 80 feet, and spreads its branches 90 feet. **Malloch’s Oak” is on the Strathallan Castle estate, near Auchterarder, Perthshire, and is supposed to be a remnant of the ancient forest which once covered this part of the country. It is supposed to be about six hundred years old, and served as a gallows for a man who was hanged by the rebels in 1745. It has a girth of about 16 feet. “James VIth Oak,” situate at Scone, near Perth, is a fine specimen, said to have been planted by “ King Jamie.” It girths 15 feet at 1 foot up, 13 feet 3 inches at 5 feet, and a height of 55 feet. At Seggieden, a few miles below Perth, in the Carse of Gowrie, there is an oak which girths 16 feet at 1 foot up, 13 feet at 3 feet, 12 feet 1 inch at 5 feet, 11 feet 6 inches at 20 feet, and 11 feet 8 inches at 22 feet ; with a clean straight bole of 28 feet, a total height of 70 feet, and spreads its branches 90 feet. “ Birnam Oak” grows near to Birnam, Perthshire, and close to the river Tay. ‘This tree is popularly believed to be one of the remains of ‘ Birnam Wood” of Shakespeare’s “ Macbeth.” It girths 23 feet at 3 feet up, 19 feet 7 inches at the narrowest part of the bole, has a total height of 50 feet, and spreads its branches 40 feet. An oak at Dunkeld, Perthshire, near what is considered to be the first larches introduced into Scotland, has a girth of 12 feet 54 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 6 inches at 5 feet up, a fine bole of 30 feet, and a total height of about 100 feet. The “ King’s Park Oak,” at Dunkeld, on the Athole property, has a circumference of 15 feet 8} inches at 3 feet up, 15 feet 2 inches at 4 feet, the narrowest part of the bole. It has a fine bole 12 feet in length, which branches into five huge limbs the size of ordinary trees. The spread of branches is 99 feet. The ‘‘Murthly Castle Oaks,” Perthshire. No. 1 has a girth of 18 feet at 5 feet up. No. 2 has a girth of 10 feet 4 inches at 5 feet up. The “Taymouth Oaks” grow at Taymouth Castle, Perthshire, and were planted in 1842 by Her Majesty the Queen and Prince Albert. They were measured in 1884—one had a girth of 4 feet 9 inches at 3 feet up, and a height of 45 feet. An oak close to the public road between Weem and Fortingal in Perthshire has a girth of 15 feet at 1 foot up, and 12 feet 6 inches at 5 feet. The “Dalgety Oak” grows in Dalgety parish, Fifeshire, on the north shore of the Firth of Forth. It has a girth of 13 feet 10 inches at 1 foot up, 11 feet at 5 feet up, a length of bole of 48 feet, and a total height of 90 feet. ; An oak at Hillhouse of Luss, on the shore of Loch Lomond, Dumbartonshire, girths 12 feet 10 inches at 5 feet up, and has a bole 20 feet in length. The “ Inchmurrin Oaks” grow on that island in Loch Lomond. They were measured by Sir Thos. Dick Lauder in 1784, but since which time there does not appear to be any record of them. No. 1 stands in the middle of the island, and measured at the above date 18 feet 1 inch in circumference. Its head was remarkable for its great leafy expanse. No. 2 girths 20 feet 8 inches at 3 feet up. No. 3 girths 28 feet 5 inches, also at 3 feet up. The ‘ Blairquhoish Oak,” Strathblane, Stirlingshire, has a girth of 15 feet at 4 feet up, and a spread of 30 yards. An oak at Hopetoun, Linlithgowshire, had a circumference of 10 feet in 1855, which had increased to 11 feet 9 inches in 1880, or 21 inches in twenty-five years. The total height was 106 feet in 1855, and 110 feet in 1880, being an increase of 4 feet. The ‘‘ King of the Forest” grows on the top of a high steep bank overhanging the North Esk river in the old Caledonian Forest at Dalkeith, Midlothian. This remnant of the old forests ON BRITISH OAKS, dD of Scotland extends to about 160 acres. The “King” has a circumference of 18 feet 2 inches at 2 feet up, 15 feet 3 inches at 5 feet up, a length of bole of 20 feet, and a total height of 90 feet. An oak at Penicuik, Sir Geo. D. Clerk’s, Bart., seat in Mid- lothian, has a circumference of 12 feet 8 inches at 1 foot up, and 10 feet 3 inches at 5 feet up. The ‘‘ Yester Oaks,” Haddingtonshire. No. 1 is in the grounds at the garden, and had a circumference in 1854 of 13 feet 10 inches at 3 feet up; in 1880, 14 feet 10 inches—an increase in twenty- six years of 12 inches. No. 2, on the left side of walk from Yester Honse to the garden, had a circumference in 1854 of 13 feet 6 inches at 3 feet up; in 1880, 15 feet 6 inches—increase in twenty-six years, 24 inches. The “Capon Tree” stands a few yards off the road in the level haugh near to the low bank of Jed water, on the Ferniehirst estate of the Marquis of Lothian, in Roxburghshire. There are differ- ences of opinion as to how the name “‘ Capon” came to be applied to the tree, but the theory that seems to find most acceptanee is, that it was the ‘meeting tree” where the tenants assembled to pay their rents in kind. Although considerably damaged by the snowstorm of December 1872, it still presents an appearance of imposing grandeur. It has three gigantic limbs remaining, and girths 26 feet 6 inches at 3 feet up, 24 feet 3 inches at 5 feet up, and covers an area of from 80 feet to 90 feet. “Old Capon tree, old Capon tree, Thou standest telling of the past. Of Jedworth’s forest wild, and free, Thou art alone, forsaken, last.” The “ King of the Wood” grows at the top of a ravine about a bow-shot distant from the last, on the opposite side of the road, and although not possessing the rugged strength of its rival, it has yet a noble appearance, and is said to be another remnant of the great forest of Jedwood, so that the ‘“‘Capon Tree” is not, as the poet sings, ‘‘alone, forsaken, last.” It girths 16 feet 6 inches at 5 feet up, and is 78 feet in height. The “ Hartrigge Oaks,” near Jedburgh, Roxburghshire, the seat of Lord Stratheden and Campbell. Nos. 1 and 2 are by the side of the mansion-house park, girthing 13 feet 10 inches and 11 feet 9 inches respectively at 5 feet up. No. 3 is near the north- east corner of the garden, and girths over 15 feet at 5 feet up. 56 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. The “ Dalwick Oaks” grow on the south bank of the Tweed at Dalwick, Peeblesshire. No. 1, on the west side of the mansion house, girths 14 feet 9 inches at 1 foot up, 10 feet 8 inches at 5 feet, a bole of 35 feet, and a total height of 80 feet. No. 2 is on the east side of the mansion, and girths 17 feet 6 inches at 1 foot up, 10 feet 9 inches at 5 feet, length of bole 35 feet, and a total height of 57 feet. No. 3 is near the bowling- -green, and girths 14 feet 10 inches at 3 feet up, and is 80 feet in height. An oak in the low ground of the Home Park of Stobo Castle, Peebleshire, girths 11 feet 8 inches at 1 foot up, 9 feet 4 inches at 5 feet up, with a bole of 35 feet. The ‘ Barjarg Oak,” in Nithsdale, is a remarkably fine tree. It has a girth of 17 feet above the roots, 11 feet 11 inches at 16 feet up, 11 feet 9 inches at 32 feet up, and 6 feet 8 inches at 46 feet up. The ‘“ Lochwood Oaks,” in Annandale, Dumfriesshire, have a circumference of 20 feet and 18 feet 10 inches respectively at ) feet up. It now only remains to be said, that in compiling the foregoing record of the oaks in England and Scotland, it is to be noticed that none in the latter country are returned as hollow, or to have been pollarded. Now it is fair to suppose that the operation of pollarding accounts for the larger girth of some at least of the English trees, and also for their being hollow. THE BEECH FORESTS OF HESSE NASSAU. 57 IV. The Beech Forests of Hesse Nassau. By GEORGE CaDELL, Esq., 14 Canning Road, Addiscombe, Surrey. Waste LAND IN GREAT BRITAIN AVAILABLE FOR PLANTING. If I venture upon a subject which is not specially set as one of the essays for the year, it is because I am unwilling to believe that the words delivered in the address to the Society of last year will, like so many words upon the subject of forestry, fall fruitlessly on the ground. It is specially necessary to remember in connection with these words, that the area of land available for the planting of trees in Great Britain is not in the strict sense of the word hope- lessly waste. It is land which, owing to various causes—foreign competition, facilities and cheapness of transport, or, as some con- tend, the fluctuations of currency, or to a combination of these causes—can no longer be profitably occupied by ordinary agricul- tural crops. No less than 1,437,000 acres of land, which in 1869 were devoted to the cultivation of wheat, have, we are told, ceased to be so occupied. They are, therefore, available for the cultivation of other crops, which, however unremunerative they may be as compared with wheat, may yet produce something, and when they are occupied by crops which do not exhaust, but, on the contrary, improve the bearing capacity of the soil, the argument, in case a different condition of matters arises, is very greatly strengthened. If no interest at all were obtained in the shape of yearly returns, the planting of such areas with trees would be amply justified by the enhanced value of the capital. The income derived from forests or woodland, in short, cannot be compared directly with the income derived from wheat or other annual produce. It is, I think, neces- sary to bear this very prominently in mind, otherwise the planting of waste lands, either in our own or other countries, is not very intelligible. Tue Strate Forests oF Hesse NAssAu. It was with a full recognition of this unobtrusive but valuable “improvement ” that I went over the beech forests of Nassau the other day in company with the Ober Forster in charge of the division. And while I have really nothing new to tell, no one with a love of forestry could go over the excellently administered forests of Prussia without either learning new lessons, or having old ones practically 58 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. and usefully enforced. For here we have, broadly speaking, no land “ out of occupation.” In the storm-swept plateaux, which produce nothing but tufty grass, we have what I suppose “ statistics” would schedule as wasteland. But even these have their fringe of weather- beaten spruce or other firs, whose flat tops afford a protection and shelter to their more favoured brethren. Nearly one-half—42 per cent., I believe, is the exact proportion—of this part of the empire is occupied with forest. And of this forest perhaps three-fourths are beech. The beech, as we know, has the credit of dominating and sub- duing all other trees which come within its influence. Neither grass nor underwood is tolerated under its shade. And if, in order to satisfy the demands of the vine-growers for stakes to support their trailing and clinging crops, some oaks are grown and main- tained, their presence in long-drawn lines appears only to emphasise the position, viz., that we are in a country of beechwoods. Not the far-spreading beech trees of our parks and meadows, but the tall plain columns crowned with a continuous canopy of leaves, through which the sun, with side-long gleam, strikes in those mingled lines of light and shade on which artists love to dwell, and in which all lovers of Nature delight. Foresters will understand what sort of woods these were, which were estimated to contain between 500 and 600 cubic metres! of solid timber per hectare,? worth something over 10,000 marks ; * while on every side were bundles of firewood, also of beech, con- taining 4 cubic metres, and worth from 30 to 40 marks each, The gross revenue derived is 40 marks or thereby per hectare, reduced by expenses of management, etc., to a nett revenue of 20 marks per hectare. I am not going to follow the statistician into any application of these figures to the waste lands of Great Britain. The agricultural statistics will, I understand, make him a present of something like 28 millions of acres of waste and unoccupied land in our islands, and allowing for deductions, after the usual gracious way of esti- mators, he can yet obtain a very handsome revenue as well as capital, on paper. I will rather pass to another item of practical experience in Nassau, which seemed to me to be rather high. The cost of plant- 1A metre is = 3.280 English feet. 2 A hectare is = 2.471 English acres. 3 A mark is = 114d. sterling. THE BEECH FORESTS OF HESSE NASSAU. 59 ing an acre of wood appeared to average about two (£2) pounds sterling, as under,—three thousand plants were put in each acre, at an average contract price of 13s. 6d. per thousand. Of this fact also I make a present to the statistician, begging him to note my cour- tesy in giving him without circumlocution the comparative cost in plain figures. But so much depends upon the size of the area planted, its accessibility by waggon-roads or otherwise, that while the above figures have a charming simplicity, their application to British soil would, or might be, very misleading. I have been talking hitherto of the Government forests of Hesse Nassau, grown, let it be further noted, on most favourable condi- ditions of soil, a loamy clay mixed with sand ; and while these occupy by far the greater proportion of the land under wood, yet its administration and government into which I need not here enter, offer no lessons to the British official—for within the limits of our own Crown forests there are “rights” which fetter in no small degree the free action of their nominal rulers. I think it well therefore to pass on to a different matter, viz., the administration of communal and private forests in Hesse Nassau, for here we may possibly find lessons and borrow examples, which may be useful to us in Great Britain, where our forests, for the most part, are in the hands of private individuals. CoMBINED EFrorts oF STATE AND PEOPLE IN Nassau To PLANT Waste LAnps. It is very certain that if we are ever able to inaugurate a useful system of forestry in this country, it will be by reciprocal help—the help of the landed proprietors in placing their woods at the disposal of the Government for such time as may be agreed on ; the help of the State in affording facilities for planting and professional advice. Exactly such a system obtains in this part of Prussia. Not only does the State help in the planting of any land that is or may become waste, but all the forests of the country belonging to muni- cipalities or to private individuals are administered in accordance with the advice of the forest officer of the district. Nay more, they may not be administered otherwise. The State prevents the waste of their property by private individuals, as well as assists in its main- tenance, and it does this in the interest of the public good. Granted that the same pressing reasons for such action do not exist in Great Britain, it cannot be for the interest of the public 60 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. good generally that so much land is lying useless, or only cultivated at a loss to its owner. And it cannot be fair to place the responsibility for such a waste of the soil on any one individual or set of individuals. We are told, of course, that the planting of trees does not pay, and the same arguments for non-action are repeated usque ad nauseam. Such excuses, for they are apologeti- cally offered, would not commend themselves—even if there were no colonial requirements to consider—to an estate administered with an eye to the future as well as to the present, such as we see in the district of Hesse Nassau. If the Nassau State forests are regulated as to their felling and replanting, on what is known as the rotation system, the land generally is utilised in perpetuity somehow. It is not all capable of producing the world-renowned Johannisberger wine, nor can its uplands compete with its valleys in the production of corn, but where fruit and grain cannot be cultivated, there is room for the useful rye and the needful forest. Each part has its capacity noted on the field map, each part contributes its share to the general good. I have endeavoured, in the accompanying Map of the topography of the district of the Taunus, one of the principal ranges of Hesse Nassau, and containing some of her most important forests, to give effect to this partition of the capacity of the soil; and I trust that my feeble efforts in this direction may be leniently dealt with, and measured rather for what they aim at than what they really are, for in carefully sketched field maps I see the beginning of practical forestry, as well as of practical agriculture, geology, or anything else. In forestry, as well as in other science, we must have a clear idea of where we are driving to, before we enter on any decisive course of action. DuTIES OF THE Oper FORSTER TO INDIVIDUALS. The details of such cultivation in Nassau are settled by what IT may call the county and municipal councils of the country, of which the Ober Forster is ea-officio a prominent and important member, He can, in effect, place his veto upon any action, such as prodigal cutting and the devotion of an undue proportion of the area of the country to the cultivation of agricultural produce, absolutely. He must be jealous, too, of what is known as the “possibility ”—that is, the fair yield of the forests—being en- dangered or exceeded. But he is, at the same time, no arbitrary THE BEECH FORESTS OF HESSE NASSAU. 61 State official, forcing an unintelligible course of action down the throats of the council. He is there as their friendly adviser, working for and with the people, considering their interests as well as those of the State, which are in reality the same. In no less friendly, if responsible, relationship does he stand to the private proprietor. He, too, is not at liberty to cut and fell his woods as he pleases. Mumm non possessor sed custos solum is the motto which may be written on his private property, for, so far as his forests are concerned, he is the steward, not the irresponsible possessor of his landed revenues. Here I may take occasion to observe that the deer and other game which are sheltered in the forests are not necessarily the property of the lord of the soil. They are exposed to auction, and the proprietor may or may not be the successful bidder. He has, at any rate, to pay for his shooting, starting on all-fours with any outsider. APPLICATION OF THESE PRINCIPLES TO GREAT BRITAIN. I may be told, on the one hand, that such a state of matters as interference with the sacred rights of a landlord would not be tolerated in Great Britain ; and I may be told, on the other hand, that there is no money available in the State treasury to assist proprietors in the planting of waste land. I do not think there is much in either objection. Many of our proprietors, in Scotland at any rate, have been accustomed to hold their lands, as it were, in trust for their successors. They have willingly embarked on “improvements” of which they could not hope to reap the benefits. They have not only expended capital on such improvements, but they have submitted to a loss of any interest accruing on such capital, They have, in a word, although they have not always got the credit for it, acted as stewards for their heirs. The other objection—“no funds available,” is the familiar cry whenever anything not palatable to the powers that be is proposed. It is doubtless perfectly right and proper that the expenditure of the national funds should be carefully scrutinised, and their disburse- ment jealously guarded ; still, they are there for the good of the nation, and should be spent in accordance with their expressed wishes. I will not here allude more particularly to the Report of the Parliamentary Committee on Forestry. This, if it erred anywhere, erred on the side of moderation—and it has suffered accordingly. I have no data by me which show the actual cost 62 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. of State aid to planting by private proprietors in Nassau, But this cannot be much, and need not be in reality anything. Nurseries, or “ Férst Gartens,” are scattered all over the country, and from these, surplus seedlings can be given to proprietors who will promise to plant them, with positive advantage to the nurseries themselves. If money is asked for them, although I will not allude to the shabbiness of the demand, they can be given at cost price, which, if conscience enters into the calculation, will be infinitesimal. It is more the moral support and recognition by the State that encourages private individuals to plant than the actual money assistance. I am getting far away, it may be thought, from my beech forests, and yet not only their dense masses, but the ‘‘ shimmer ” of their countless leaves in the mixed woods of the country, are with me as I write. I see, too, the leaf-covered tunnels of beeches, which form the favourite alleys of the private gardens. And I see, in what Selby, I think, tells us was its original habitat, the red foliage of the copper beech contrasting with and toning down the mass of green. If I have unwarrantably made use of them, in the hope of attracting further attention to the policy of which they are the living tokens—a policy of pulling together by Government and people, under circumstances of difficulty, too intricate for their separate and divided efforts—I shall ask the pardon of my readers. I have not pulled the bow too strongly. I have carefully refrained from even mentioning those other measures of “relief” to proprietors of waste lands, which may commend themselves to the attention of our newly formed County Councils. I have not set forth an ideal, but an existing, and, I may add, a successful state of matters; and in doing so I have purposely avoided all those details of forest administration which have been once and again explained by far abler pens than mine ; and, except for the purpose of giving some idea of the size of these grand beech forests, I have kept clear of statistics and figures, which may be elsewhere ascertained. Those who visit our Continental neighbours will do well to examine for themselves the raison d’étre of the forests of the country, which will everywhere afford them at once a playground and a study. THE NATURAL REGENERATION OF WOODS. 63 V. The Natural Regeneration of Woods. By W1LLtAM SOMERVILLE of Cormiston, D.dic., B.Sc., F.R.S.E., Lecturer on Forestry, Edinburgh University. If the rearing of a young wood, by means of self-sown seed, upon the same ground as that previously occupied by an older generation of trees, is to be successfully accomplished, an amount of skill is demanded of the forester which can only be derived from careful training, long practice, and an intimate knowledge of the requirements of the trees placed under his charge. The difficulties are increased by the fact that generally a long series of years must elapse from the initial stages of the process till the regeneration is accomplished, so that, as frequently happens, the work is not directed in all its stages by the same hand, and unless each successive step be made at the right time and in the right way, total or at best partial failure must be the result of even the most auspicious beginning. In countries where State forests bulk largely in the wooded area, and where consequently ample provision is made for the training of foresters in the science and practice of their profession, no difficulty is experienced in bringing to a successful issue any sylvicultural system which may be inaugurated. As the men who have guided the work are one by one removed, their places are taken by those who have received their training in the same rigorous school as that in which they themselves were educated, and who are therefore fully qualified to carry forward the work, long since begun, on the lines which experience has shown will ultimately lead to the greatest success, The impediments which obstruct the path to the successful formation of woods by means of self-sown seed are so great, and the advantages and convenience of stocking the ground by artificial means, are in most cases so apparent, that in all parts of the world, whenever forests have been brought under scientific sylvicultural treatment, the cases where natural systems of renewal are held to offer greater advantages than artificial systems gradually diminish, till finally they form but a small proportion of the whole. Still it is highly improbable that artificial planting and sowing will ever in all places and under all circumstances completely displace natural sowing, so that it is not too late to 64 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. consider the cases and conditions under which the latter system may be most advantageously adopted, and to look as shortly as may be at the best means of attaining the end in view. Speaking generally, it may be said that the fulfilment of the following conditions would chiefly influence the adoption of natural regeneration in preference to artificial restocking. 1. Where the state of the surface of the ground is such as to offer the conditions requisite for a good seed-bed without the aid of any artificial preparation. This consideration gains additional weight when the financial condition of the estate is such as to make the restriction of all outlay to the very minimum almost a necessity, as well as in cases where the quality or value of the timber is so low that, in order to get even a small balance on the right side, the expenses must be kept down to the lowest point. In outlying districts, also, where the cost of conveyance reduces the profits within very narrow limits, it frequently happens that the only way to secure any return at all from the woodlands is to avoid all outlay in their formation. The cases where no artificial aid is required to bring the surface of the ground into a suitable condition for the reception and germination of the seed are, comparatively speaking, few, and are for the most part only to be looked for in close well-managed woods of shade-bearing trees (beech, silver fir, etc.), and then only if the trees are not too old, and in the absence of destructive gales. In many other cases, no doubt, a patchy imcomplete stocking may be looked for, but that perfect regularity in the distribution of the young plants, which has so much to do with the future success of the wood (and a considerable departure from which must bring, at least, partial failure), is attained without artificial preparation of the ground in very few cases indeed. If weeds must be removed, and the surface broken by means of hand implements before a good seed-bed is secured, the expense incurred is frequently much greater than the cost of stocking by means of planting. 2. On steep, bare, rocky declivities, and in high exposed situations, the system of clear-felling one crop of timber, and then restocking the denuded area by artificial means, admits of serious loss, occasioned by the washing action of rains and melted snow during the time that the surface is destitute of trees, or before the young generation has developed sufficiently to shade the ground, Especially undesirable is it to clear-fell a wood THB NATURAL REGENERATION OF WOODS. 65 where the surface is thickly strewn with large boulders, or where the bare rock projects in large masses, because so long as a close wood is preserved the leaves accumulate to form valuable plant- food, and, in coniferous woods, moss grows in great luxuriance, so that a good seed-bed is provided even on what would otherwise be a bare rock-surface, and the young seedlings ultimately push their roots into cracks or crevices, or ramify over the rocky surface till they get at better soil, and so large well-grown trees are not unfrequently to be seen in situations which they could never have occupied had they not been self-sown. Let such an area be cleared of its trees even for a few years, and the moss and humus will, under the combined influence of sun, wind, and water, entirely disappear from the rocks and boulders, for shade and a humid atmosphere, such as are to be found in a dense wood, are absolutely necessary for the formation of forest humus, and the production of a rank growth of mosses. The fact must not be overlooked that rocks covered by decaying vegetable matter or mosses weather much more rapidly than where unprovided with a covering, for the carbonic acid gas resulting from decomposition of the humus, and the solutions exuded from the roots of plants, act far more powerfully than rain or the atmosphere in corroding rocks and rendering their ingredients soluble, When a locality, in the enjoyment of unrestricted sunlight, is apt to produce a very rank growth of ground vegetation, such as ferns, heather, blackberries, large grasses, etc., it is often advantageous to restock by self-sowing before felling all the old trees, for in this way the weeds are kept in check till the young trees have had time to surmount them, ‘This is often the case on moist, rich, loamy soil, especially if calcareous. Here such a rank growth of herbaceous vegetation would spring up after clear-felling, that small slowing-growing trees would be apt to be smothered, or one would be compelled to give them light and air by mowing the weeds, unless recourse was had to the expensive operation of restocking with extra large trees. 3. A third case where natural regeneration may be advan- tageously resorted to occurs where we have to deal with species of trees which are very liable to be injured in youth by too powerful atmospheric agencies. This is the case more especially with the beech and silver fir. When young both these trees are very sensitive to frost, heat, and drying winds, from which they can VOL. XIII. PART I. E 66 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. be best protected by regenerating under overhead shade. This protection can be procured as well when the young generation is formed by artificial sowing or planting under a shelter wood, as when from self-sown seed, but if the trees which give the shelter can also yield the seed, it is a manifest advantage to utilise them in this way as well. To the two species just named may be added the spruce, which, on account of its shallow roots, is apt to perish on dry land during the first few years of its existence, unless the surface soil be kept sufficiently moist, and nothing conduces more to this end than the shading of the ground by overhead foliage, and the exclusion of drying winds. As we shall see afterwards, the natural regeneration of spruce woods is attended with great difficulty in windy regions, but where a locality is sheltered from violent gales the system may frequently be advantageously adopted. 4. Where young trees are liable to be destroyed by insects, it has been found advantageous to rear them for some years under the shade of an older generation, for insects prove much less destructive under shade than on a cleared area. Here, again, the shading trees may also be the mother-trees, if no serious obstacles interpose to their being used as such; and the ravages of the cockchafer grub and the pine weevil may often in this way be successfully combated. Where any return can be got from the roots and stools, the practice of felling conifers by stubbing their roots is strongly to be recommended, as it is very effective in keeping down the increase of all sorts of destructive insects, and, at the same time, the ground is brought into a suitable state for the reception of the seed. 5. Trees which grow well under the shade of others are much the most suitable for natural regeneration, and now the system is being more and more applied in their case alone. Such trees are known as shade-bearers, and include the silver fir, beech, spruce, lime, and one or two others of minor importance, notably the yew, which develops almost as rapidly under considerable shade as in an open situation. There are two distinct cases in which an area may be supplied with self-sown seed, and where consequently a system of natural reproduction may be put in force. The one is where the seed is furnished by trees (the shelter-wood) occupying the area to be restocked, and the other where the mother-trees stand at a greater or less distance from it. Inthe former case, the general conditions of the situation and the growth of the seedlings are influenced by THE NATURAL REGENERATION OF WOODS. 67 the overhead shading ; in the latter there is no vertical shade or shelter, though there is usually lateral protection. The former of these two cases in its various modifications being the more import- ant, may be taken first. The regeneration of a forest on a shelter-wood system may be accomplished in various ways, the most common being that where the whole is taken in hand at one time, that is to say, the several processes or stages in the operation of natural regeneration proceed simultaneously throughout the whole wood. When it has been resolved to renew a wood by natural seeding, all efforts must be directed towards providing conditions which will be likely to bring about a successful result. It comparatively seldom happens that the surface of the ground is naturally in a proper state to receive the seed, and that the number and distribution of the trees over the area are such as to secure the proper conditions as regards light for the health and development of the young seed- lings. It therefore becomes necessary, afew years before the actual shedding of the seed is to be expected, to undertake various pre- liminary operations in order to avert as much as possible the chances of failure. If the closeness of the wood is such that no weeds, but only dead leaves and twigs, cover the surface of the ground, this preparatory stage offers but few obstacles. It is then only neces- sary to make several very moderate fellings in order to hasten the decomposition of the raw humus, and to bring about a perfectly regular distribution of the old trees, so that every part of the ground may receive the necessary supply of seed, and at the same time be equally shaded. At first attention should chiefly be directed towards removing the smaller class of trees, namely, those that are overgrown, diseased, or poorly developed, and therefore not likely to bear much seed, as well as those species which it is not desir- able to have represented in the next generation. If we are dealing with a mixed wood, the fellings should also be directed towards proportioning the trees as they are intended to be represented in the young wood, due regard being taken of the fact that some species produce far more seed than others, and that some seeds, especially those provided with wings, possess special facilities for distribution. The advance fellings may take only one or two years to accom- plish, or as many as ten or fifteen if the wood is situated ina region subject to heavy gales, or if the trees are of a shallow-rooted species, for in these cases the process of thinning must be very slowly 68 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. performed, in order that the trees which are left may develop new roots, and so gain stability sufficient to enable them to withstand the action of wind. In the early part of this preliminary stage, supposing it to embrace several years, the felling must not be so heavy as to cause inter- ruption to any considerable extent to the leafy canopy, for were such brought about, sufficient light would reach the ground to enable strong weeds to gain a footing which would make the surface very unsuitable for the reception of the seed, and, besides, owing to direct insolation and the entrance of drying winds, great loss of fertility would result. If the wood is rather thin, a proper advance felling may be altogether dispensed with. There is, however, one case in particular where very considerable felling is necessary, namely, in very dense woods of broad-leaved trees, especially beech. In such a case the ground is covered by a thick layer of humus, which is only partially decomposed. Such a covering would not interfere with the ger- mination of the seed, but would be apt to bring about the death of a large number of the seedlings during the first few weeks of their existence. This is due to the fact that a layer of raw humus is subject to great variations in the degree of moisture, so that, if the rootlets of the young plants ramify in this material alone, they are not so able to withstand any considerable spell of dry weather as they would be were they fixed in the mineral soil lying underneath. So long as the layer of leaves and twigs is shaded from the sun, sheltered from the wind, and protected from the rain by a dense mass of umbrage, decomposition goes on but slowly, especially on cold stiff soils; but the process may be much accelerated by the removal of a considerable number of trees, and the consequent admission of light, air, and rain. If the desired result is not attained by thinning alone, recourse must be had to the removal, by means of rakes, of part of the sur- face covering where densest, or the mineral soil may be stirred up and mixed with the raw humus by the aid of mattocks or heavy hoes. The former of these operations involves a cost of about 10s. per acre, the latter costing about twice as much, and both may generally in great part be avoided by bringing the wood into such a state that the natural processes of weathering can be utilised. If artificial aid must be adopted, it should not be put into force till there is an immediate prospect of seed being borne, for if some years elapse between the preparation of the soil and the seeding, THE NATURAL REGENERATION OF WOODS. 69 the quality of the seed-bed will suffer severely, and the labour expended upon it may be for the most part lost. Not only do the advance-fellings, if properly performed, prepare the seed-bed, and adapt the trees to offer greater resistance to storms, but they also induce the mother-trees to produce a large crop of seeds. This is the natural result of admitting light to the lower branches of the crowns, and is most apparent in cold districts, such as high regions, and north or east slopes. In many woods one finds scattered here and there in small groups, or as single specimens, young trees which have sprung from naturally sown seed. These usually occupy the somewhat opener parts of the wood, which are accessible to direct sunlight, but whether they should be retained and fostered or be cleared away, depends on such circumstances as species and quality. If they belong to a kind of tree which it is considered desirable to have represented in the new wood, it is well to retain them, and to encourage their development by cutting out the old trees in their vicinity which are interfering with their growth, provided they have not grown so long in restricted light as to be incapable of ultimate normal development. Most in this respect depends upon species. Silver firs, for instance, have wonderful recuperative power, and may exist for more than fifty years in dense shade, and still retain their vital powers practically unimpaired. During this time they will have made but slow growth—the wood rings, in fact, will often be found to be of hair-like fineness—but when gradually placed in the possession of a greater amount of light, the foliage increases in quantity and becomes darker in colour, the wood-rings become broader, the leading shoot lengthens, and in a few years what before seemed a stunted bush acquires all the characters of a vigorously growing tree. In a close, or moderately close, wood any advance growth which may be met with must, from the very nature of things, consist of some shade-bearing species of tree, for no young light-demanding tree could exist for any length of time under such conditions. Where, however, the wood is open, or where blanks have been occasioned by any cause, advance growth of such light-demanding trees as the Scots pine, birch, etc., may be met with. It is but seldom, however, that such advance growth can be utilised, for, if light-demanding trees have become stunted when young, they never recover to such an extent as to form desirable objects for future encourgement. They should, therefore, be cut out in the pre- 70 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. liminary stage, as should also all growth of the nature of brush or underwood, e.g., sloes, aspen, bird-cherry, willows, ete. These frequently prove a serious annoyance in natural regeneration, because, when cut over, they reproduce themselves by means of stool or root shoots, which, growing with great vigour, are apt to choke out the slower growing seedlings. When as much thinning has been done as is considered safe, attention must be directed towards discovering the first signs of an approaching seed year. In the case of the Scots pine, and the genus Pinus generally, where two years elapse between the time of flowering and the ripening of the seed, one always receives sufficient intimation that the production of a full crop of seed is near at hand. In the case of most of the other important trees, however, no such long intimation is given, for they ripen their seeds in the same year as that in which they produce the flowers. However, if one is watchful, a year’s warning at least can usually be obtained, for, on account of their larger size, and in other ways, the flower- buds can be distinguished from ordinary leaf-buds in autumn, or, at any rate, in the course of the winter and spring. In the case of some trees, large quantities of seed are produced every two to three years, whereas many trees do not bear oftener than once in eight to ten years. Where we have to deal with a species of the latter class, ¢.g., the beech, we must be specially careful not to let the opportunity slip of availing ourselves of a seed year; but, at the same time, the work of preparation must not be completed too long in advance, for unfavourable weather may intervene during the time of flowering, or in the succeeding summer before the fruit has ripened, which may cause the yield of seed to be very dis- appointing. Where the wood is of moderate dimensions it is best to wait till autumn before completing the advance fellings and final preparation of the surface, but where large areas have to be regenerated it is scarcely possible to delay beyond midsummer. In either case, however, if a large production of seed be regarded as tolerably certain, the wood must be brought into that state in which it will be most favourable for the reception and germination of the seed, and for the development and protection of the young plants. At this time the heaviest trees must be felled and removed, partly to provide the future young trees with light as well as to facilitate the entrance of rain and formation of dew, and partly because the removal of specially heavy trees after the young seedlings occupy the ground would be sure to damage them exces- THE NATURAL REGENERATION OF WOODS. it sively. At the same time attention should be given to felling all trees which are provided with low-reaching branches, as these, owing to the excessive shade which they produce, are apt to act prejudicially on the young generation. If, however, such trees must be retained, in order to furnish the necessary seed, or for purposes of protection, then all their branches ought to be removed for 20 feet from the ground. The species of tree, kind of soil, climate, etc., must regulate the amount of shading which should be retained at this time ; or, what is the same thing, these considerations should decide the extent of the seed felling. In the case of shade-bearing trees, it is usually sufficient to bring the wood into such a state that the edges of the crowns of the trees are separated 3 to 9 feet from each other, which implies the removal during the advance and seed fellings of from a quarter to three quarters of the original number of trees. Light- demanding trees require at least twice this amount of thinning unless a subsequent felling can be made very soon after the seed year, in which case it is better not to fell too heavily at first for fear the seeding should not be successful or complete, when it may be necessary to supplement by utilising a second seed year. As a general rule, one should not make the wood too thin where the land is of the character which predisposes it to produce a strong growth of weeds, for the only way of keeping them in check is to retain a considerable amount of shade. Here, again, species must be taken into account, for the rate of development in youth varies greatly, some—for instance, the silver fir—growing very slowly when young, and consequently being lable to be choked by rank vegetation, while others, such as the larch, grow so rapidly as soon to be out of all danger from this cause. In frosty localities, or in the case of tender trees, more shading should be retained than under opposite conditions ; and the same is true where insects are numerous, or where the soil is very dry and apt to suffer from excessive drought. Should artificial assistance be necessary, the stage of the seed felling is the most suitable time to complete the preparation of the seed-bed. Ifthe advance fellings have been too heavy, or if severe gales have occurred, a considerable amount of ground vegetation may have found a footing. This must be got rid of, at least in part; but if not very plentiful, the disturbance of the surface occasioned by felling and dragging the trees is usually sufficient preparation. If the trees have been felled with their stools attached, 72 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. and if the holes thus made in the ground have been carefully levelled, an excellent seed-bed is produced at such places. A practice which cannot be too highly recommended, both on account of its efficacy and cheapness, is that of allowing swine to run in the wood during the summer, autumn, and winter of a seed year. These creatures grub up the ground, spread the heaps of dead leaves, destroy enormous numbers of grubs and mice, and in various ways prove extremely useful. Even in beech or oak woods, where one would expect them to destroy considerable quantities of fruit, they are found to do far more good than harm. In the case of woods consisting of light-demanding trees, ¢.g., Scots pines, larch, etc., where it has not been necessary to under- take any advance fellings—that is to say, where the seed felling has been the first felling of all, the surface of the ground is generally provided with a thick covering of moss or grass, which must be partly removed before successful germination can be looked for. If horse implements, such as ploughs, harrows, or grubbers, can be worked it is sufficient to scarify the ground in narrow lines about 3 feet apart ; but if, as is oftener the case, the nature of the ground does not admit of horse labour, there is no help for it but to remove the mossy or grassy covering in stripes or patches by hand labour, with the aid of rakes, hoes, spades, or mattocks. Where one has to deal merely with moss, raking is quite sufficient, the preparation of an acre requiring four or five days. If heavy hoes or mattocks must be employed (and these must be resorted to when an actual sward of grass is present), the expense mounts up rapidly, as it may take ten to twenty days to prepare an acre, the time depending on the amount of preparation deemed necessary, as well as upon the nature of the situation. Where ploughs can be used, and if single furrows be turned at distances of 3 feet, at least two acres may be overtaken in a day. In the case of the lighter seeds, those of the pines, firs, larch, birch, ete., no covering is necessary, and consequently, if deemed advisable, the preparation of the ground and the felling and drag- ging of the timber and branches may be completed before the seed is shed ; but where one is dealing with large seeds, such as those of the oak, beech, or chestnut, some covering must be provided. This may be obtained by raking the surface with heavy rakes imme- diately after the seed has fallen, which of course adds considerably to the expenses of regeneration ; but in practice it is found better, if possible, to delay the preparation of the surface by raking, ploughing, THE NATURAL REGENERATION OF WOODS. te -or hoeing, till just after the trees have shed their seed, when the preparation of the seed-bed and the covering of the seed may be performed by one and the same operation. Where no artificial preparation is necessary, but where it is desirable to cover the seeds, it is well to delay making the seed-felling till late in winter, when the disturbance to which the surface of the ground is subjected, by the felling and dragging of the timber and branches, usually suffices to bury the seeds to the required depth. If the ground has been sufficiently supplied with seed which has germinated satisfactorily, the future use of the old generation of trees is chiefly confined to protecting the young plants against extremes of temperature. If, however, owing to some cause or other, the stocking of the ground is defective, the old trees must be still further utilised for the production of seed. For this purpose a sufficient number must be retained till a second seed year has come round, their distribution over the area being regulated by the appearance of the young wood. If the blanks or patches which are insufficiently stocked be of inconsiderable size, they may often be filled up by transplanting young trees from parts of the wood where the stocking is so dense that they can be easily spared. These young trees should be lifted with balls of earth adhering to their roots, and as they need not be carried far, the operation is not an expensive one, and the results are excellent. If this practice be adopted—and leaving advance growth out of the question—the young wood is absolutely even- aged, for all the trees have been produced from seed shed during one year; whereas if two or more seed years have been utilised, differences of as much as ten to fifteen years in the age of the young trees are unavoidable. In later life such slight differences become unrecognisable, so that, to all intents and purposes, such a wood may be regarded as even-aged, though, strictly speaking, it is really uneven-aged. In those parts where the regeneration is quite satisfactory, and where consequently no more seed or plants are required, the length of time during which the old trees should be retained is regulated by various considerations. In the case of shade-bearing trees, which are liable to suffer from frost, the old trees should not be removed too soon, for though their shade will somewhat retard growth in the younger trees, it will not cripple them, and will prove very bene- ficial in the way of protection. Where, however, we are dealing with light-demanding trees, the subsequent felling, or light-felling, 74 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY, as it is sometimes called, must on no account be long delayed, other- wise the effect on the young generation will prove very prejudicial. In the latter case, the subsequent felling should be made in the first, or at most in the second, autumn after the seed has germinated, when the whole of the trees may be removed in either one or two fellings ; or twenty to thirty per acre may be retained as standards to grow through the whole of the second rotation, and so form extra heavy timber. In the case of the beech, spruce, silver fir, etc., the subsequent felling should be subdivided into several fellings, the last of which—~.e., the final felling—need not be undertaken till ten or more years after the seed felling, though during that time a con- siderable number of trees should be removed every year or so in order to satisfy the increasing demands for light on the part of the young trees. Speaking generally, the subsequent felling should be most quickly performed on poor dry land, because the shade trees partially prevent the entrance of rain, and yet are so scarce as not to be able to hinder evaporation to any appreciable extent. On north or east slopes, also, or at high elevations, where the growing season is short, the retention of many old trees for a considerable period would retard growth in the young trees to an undesirable extent, On the other hand, the subsequent fellings should not be hurried where late frosts are almost annual in their recurrence, as well as on all strong soils, especially those resulting from the weathering of limestone, basalt, or porphyritic rocks, because there strong weeds are to be apprehended ; and besides, on such rich soils trees can bear an amount of shading with impunity which would soon kill them on poorer soils. It is needless to say that very great care and skill are required in felling the old trees after the young trees occupy the ground, so as to prevent the latter being excessively damaged. Unless snow cover the ground, all operations should be suspended during hard frost, as at that time the young stems are very brittle, and specially liable to be broken. Where the trees are provided with large branches, they must be pruned before being felled, an operation entailing a great deal of labour, but one which it is impossible to avoid. The system which has been sketched, namely, the simultaneous natural regeneration of whole woods under shade trees, has the advantage that the operation in all its phases is confined to a limited period, and is concentrated into a compact area, so that the work can be easily controlled and directed. If all goes well, then a large THE NATURAL REGENERATION OF WOODS. 79 measure of success may be looked for, but if the operations have not been skilfully conducted, or if severe gales have overturned many of the mother-trees before seeding has been accomplished, and the young plants have become securely established, or if it should turn out after seed-felling that the trees are so old as to be incapable of bearing a sufficient quantity of good seed, then, indeed, the con- sequences may be most disastrous. In the event of failure from any cause, the surface of the ground is long deprived of the shade and shelter afforded by the young crop of trees, and if the situation is naturally a poor one, that is to say, if it has the store of forest humus chiefly to thank for its productive power, the fertility which has been gradually accumulated during the previous rotation is soon dissipated to such an extent that the restocking of the ground, either artificially or naturally, becomes a most difficult matter. If the soil is naturally rich, then the same danger sinks in significance, though only in situations of the very highest quality can it be said to dis- appear altogether. It is always well to guard against great calamities by not taking very large areas in hand at one time. Large woods should be divided into compartments of moderate size, which may be regarded as separate woods, and be regenerated at different times. The system works best where the area is pretty flat and the soil of the same character throughout, because in that case the closeness of the wood and the development of the trees are uniform over the whole area, so that there exists no necessity to hurry the operations in one part and delay them in another. Having looked somewhat carefully at the foregoing system, the others may be dealt with much more shortly. The advance, seed, and light fellings are more or less common to all systems, and therefore what has been already said in connection with them need not be repeated. The system which we have already considered undergoes an im- portant modification when a wood, instead of being simultaneously regenerated over the whole area, is divided into a number of bands or stripes, each representing some particular stage of regeneration. This gives rise to the system known as the shelter-wood band system, under which one commences the process of regeneration at one side of the wood, and proceeds systematically towards the other. It is of great importance to begin at the side of the wood farthest away from the quarter from which the severest gales blow —that is to say, in this country one would begin on the east or 76 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. north-east side, and work towards the west or south-west. By so doing a compact mass of wood is interposed between the gales and the part of the wood undergoing regeneration, so that the trees which are semi-isolated in the advance, seed, or subsequent stages are well protected, and not likely to suffer much from gales, and the partially exposed surface of the ground is sheltered from drying winds. In the simplest form three bands are in hand at the same time. One of these bands (L) is in the light-felling stage, another (8) adjoining is in the seed-felling stage, while a third (P) is in the preparatory stage. All the wood lying to the westward of band P is still untouched, and consequently, so far, is not embraced by the process of regeneration. | Intact Wood P sage | West Side The simple case which we have just glanced at is often applicable to woods consisting of light-demanding trees where little advance felling is necessary ; in fact, it often happens, under such circum- stances, that band P can be dispensed with altogether, and so we have only to deal with bands S and L. On the other hand, where much advance felling and preparation are necessary, as is generally the case where the wood is very dense, or where we have to deal with trees provided with very shallow roots, as well as in windy regions, it is not sufficient to have only one band in the preparatory stage at any given time, but several must be simultaneously under- going moderate felling—that is to say, there must be several P bands. Another modification occurs where groups of serviceable advance growth fall to be dealt with. These will be met with irregularly distributed throughout the untouched wood, and light must be THE NATURAL REGENERATION OF WOODS, an given to foster their development by moderate fellings being made in their vicinity. As the regular regeneration bands move forward, the advance growth groups are embraced by them, so that it may happen that final felling is being done in these groups at a time when the band in which they are then situated is only in the preparatory or seed stage. Although such a case introduces us to a compound system (composed of the union of the shelter-wood band system and the one which we shall look at presently, namely —the shelter-wood group system), it need present no extraordinary difficulties, and, if the groups of advance growth are of good quality, it would be most irrational to neglect them. As regards the breadth and length of the bands, no hard and fast rule can be laid down. It is usual to make the breadth correspond to the height of the trees (60 to 100 feet), while the length is regulated by the dimensions of the wood measured from north to south. If the length of the wood from east to west is very great, and if, at the same time, the length of the bands (7.e., the breadth of the wood) is short, it may be advisable to commence regenerating at two places, one on the extreme east and the other in the middle ; or the process may be hastened somewhat by making the bands elbow shaped instead of straight, but this must only be done in well-sheltered districts. Where elbow-shaped bands are adopted, Se tile or where it is impossible, owing to the configuration of the ground, to fell directly towards the wind, it is often advantageous to leave a part of the wood on the west side intact, so as to act as a shelter- belt and break the force of the gales. This system offers several advantages as compared with the fore- going one. Here the danger of total failure over a large area is avoided, the risk of the seed and shelter trees being overturned is not so great, and as the parts of the wood which are light thinned are, for the most part, sheltered from sun and wind by a close wood lying to the south-west or west, soil fertility is well Side Intact Wood West 78 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. preserved. All trees may be treated under this system, but it is specially suited to the wants of the Norway spruce. The objection that the regeneration of a wood in this way is a process slow of accomplishment has not much force, and is altogether lost sight of after a wood has once been gone over, for then we have to deal with a series of age classes systematically arranged, the oldest of which is taken in hand first, and at a time when those which are younger are not ready for regeneration. When regeneration is accomplished in neither of the two ways already considered, but by taking certain irregularly distributed groups in hand as occasion demands, a third system presents itself, which is known as the shelter-wood group system. Under this system all groups of advance growth are specially attended to, and their occurrence regulates, to a considerable extent, the points where felling should be done. Groups of young seedlings which have found a footing in the open parts of the wood, even though embracing an area of only a few square feet, must not be over- looked, so long as they are not stunted in growth, and, owing to this cause, incapable of future development. Advance or seed fellings, properly so called, cannot be spoken of in-connection with these groups, for they have sprung into existence without any artificial aid being given. They must, however, be fostered by light fellimgs being made round about them, and these fellings become advance fellings for other groups which will subsequently spring up in their immediate neighbourhood. By this means each group is constantly being enlarged, like a crystal or a snowball, by the deposition of material on the outside, until ultimately, by group joining on to group, the regeneration of the whole wood is accomplished. Although groups of advance growth form special objects of care under this system, still there are certain circumstances when points of the wood must be attacked for other reasons than the fostering of young trees already established. This happens where patches of old trees occur which are in an unhealthy state, owing to such causes as insect or fungoid attack; or where, in a mixed wood, certain species are ready for felling sooner than others; or where extra old and heavy trees, the survivors of a former generation, have reached maturity, as well as where groups of trees have ceased to grow owing to the effects of situation, etc. In removing old trees, in order to provide sufficient light for the young groups, one must look not only to the vertical shade, but THE NATURAL REGENERATION OF WOODS. 09 also to that which is due to the laterally situated trees. Where a group is surrounded on all sides by a dense wood of tall trees, most light will be let in with the least amount of felling by attacking the old trees on the south and west sides rather than by felling on the north and east sides. Regeneration of a wood under this system usually takes from thirty to fifty years to accomplish, and the result is an uneven-aged wood, with the various age classes distributed throughout in groups of all conceivable shapes and sizes. Provided the management be firstclass, this system has much to commend it. It recognises and provides for temporal and local variations, and admits of parts of a wood being taken in hand at a time when they most require regeneration, and when the operation would be most likely to succeed. It preserves soil fertility from loss better than the two systems already considered, for the surface of the ground occupied by the groups is protected from the sun by the overhead foliage, and from the entrance of drying winds by the intact wood which surrounds them, or by the young groups which have previously been established. It is most in vogue in mixed woods of shade-bearing trees, especially where, owing to greater exposure of certain parts, soil fertility is being reduced, or where, owing to any cause, closeness has been partially interrupted and advance growth groups have established themselves. A modification of the last system is made use of in some coun- tries, and differs from the one we have just noticed, in so far as it does not deal with groups of young trees so much as with isolated examples. These are tended in exactly the same way as the groups in the former case, but here the regeneration is extended over the whole length of the rotation, so that all seed years are utilised, and one finds represented in the wood trees of all ages, from the one- year-old seedling up to those which are perfectly mature. This system ensures a constant covering for the ground, and is therefore most adapted for districts where violent. gales are very frequent, as well as for steep declivities, where the action of snow or water would be apt to rush away soil or rocks were the wood clear- felled even in part. , It is the system which most effectually preserves soil-fertility, for as the ground is constantly shaded, no opportunity for loss is ever presented. It can only be practised in the case of the most decidedly shade-bearing trees, such as the silver fir and beech, though in wood- 80 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. lands of small extent, where constant care can be given, it is not inapplicable to the regeneration of spruce woods. The four systems which have been described have this point in common, namely, that the seed is furnished by trees actually oceupy- ing the ground to be restocked. We shall now look for a little at the other division of the subject, namely, natural regeneration of a clear-felled area by means of seed furnished by trees situated to the side of that area. Here the seed is borne from the mother-trees to the clear-felled ground by the wind, or directed by the slanting course imparted to its fall by the wing with which many seeds are provided. It is therefore evident that the system is only applicable to cases where one has to deal with light or winged seeds, except where, as on the side of a declivity, the cleared area lies at a lower elevation than the mother-trees. In such a case even large and heavy seeds, such as beech nuts, acorns, and chestnuts, may, by rolling down hill, be disseminated for a con- siderable distance from the trees which produced them. As a matter of fact, however, this system is hardly ever practised, except in the case of woods consisting of pines, larch, firs, spruce, elms, birch, willows, and acers ; but in the case of these trees, if properly conducted, it yields satisfactory results. The first consideration must here be given to the direction from which the prevailing winds blow, so that the area to be sown shall lie on the lee-side of the mother-trees. A band of trees is cleared only during a seed year, and the felling, dragging, and carting of the timber over the bare ground is generally all the preparation which the surface requires. One band must be carefully regenerated before any more felling is done, otherwise an imperfectly stocked wood will be sure to result. When it has become evident that little more is to be hoped for from the self-sown seed, blanks are filled up by transplanting young trees with ball-roots from the denser parts. The breadth of the band varies with the height of the trees and with the species. In the case of the acers, ash, and silver fir, the breadth should not exceed about twice the height of the trees, with the spruce and Scots pine it may be as much as four times the height, while in the case of the larch, elm, willows, poplars, and birch it may be increased to eight times. Under this system the young trees are, from the first, placed in the possession of ample light, even though a dense wood lies to the south or west, and consequently it is specially applicable in the THE NATURAL REGENERATION OF WOODS. 81 regeneration of woods composed of light-demanding trees. It may also be usefully put into practice on steep slopes, the bands when run from the base towards the top of the hill forming a convenient passage for the transport of the timber. Blanks in woods, if of only moderate extent, may frequently be restocked by adopting this system, provided the ground is in a suitable state for the reception of the seed, which is blown from the surrounding trees to the bare surface. In countries such as North America, Scandinavia, Russia, etc., where one is more concerned with felling the timber of the primeval forests than with restocking the ground, all the regeneration that is often practised is by means of seed naturally carried from trees situated at a great distance from the cleared area. Under such cir- cumstances anything approaching to a complete restocking of the ground with valuable trees cannot be looked for, as the seeds of the best trees, even when assisted by the most favourable winds, can only be carried for a few hundred yards. On the other hand, such light seeds as those of the birch, poplars, aspen, willows, etc., may be borne for many miles, and so it happens that when the conifer- ous forests of new countries are felled or burned, their place is taken by comparatively valueless trees. In the foregoing pages, all the important systems of natural regeneration by means of seed have been touched upon. Care has been taken to avoid advancing mere theories, attention being entirely given to practical methods which have stood the test of long experi- ence. There appear to be, however, unsurmountable obstacles in the way of any of them being made practically applicable to any great extent to British conditions. Natural regeneration is almost impossible where ground game is as abundant as it generally is in this country. Here, too, there are very few estates where woods are managed on a well-organised working plan, that is to say, there does not exist, nor can there under the system of private ownership, long sustained continuity in the administration of our woodlands. For- tunately several circumstances combine to place this country in an almost independent position as regards natural renewal. Our humid atmosphere does not make the preservation of soil-moisture by con- stant shading the paramount consideration which it becomes under the conditions of a continental climate, though in our drier districts it is still most important. Nowhere are our fertile valleys threat- ened by destructive avalanches of snow or earth consequent on clear-felling a mountain slope. All parts of the country are in good VOL, XIII. PART I.

In cultivating conifers one should, in the absence of rank herbage, make use of untransplanted seedlings, and insert them, not with a spade, but with a single-handed planting-iron. In this way land may often be perfectly stocked at a cost not exceeding 12s. per acre, a sum generally exceeded by natural regeneration. My conviction is that our foresters should very seldom indeed aim at a hard and fast system of natural regeneration, but while making use of all serviceable advance growth, should depend on artificial planting, or, under certain circumstances, on artificial sowing, as the mainstay of British sylviculture. “OLD AND REMARKABLE. TREES IN NORTHAMPTONSHIRE. 83 VI. Old and Remarkable Trees on the Estates of Earl Spencer in Northamptonshire. By F. Mircurxy, Forester, Harlestone, Northamptonshire. The estates of Althorp and Harleston lie in the mid division of Northamptonshire, and are, geologically speaking, on the Oolitic formation. The soil varies from stiff loam to rich red loamy earth, resting on sandstone strongly impregnated with iron. Althorp Park comprises an area of about 550 acres, is well sheltered, and beautifully wooded, the surface rising and falling in gentle undulations. The soil generally is favourable for the production of large hardwood trees, and lies at an elevation varying from 320 to 450 feet above sea-level. The average annual rainfall being about 25 inches. In the following report, the particulars are given of twenty remarkable trees on these estates, all of which stand within a mile and a half of Althorp House, the seat of Earl Spencer. There are avery large number of other trees standing in Althorp and Harleston Parks, which are worthy companions of the “ monarchs ” of the forest which are described in this report. To a forester, one of the most interesting features in Althorp Park is the number of inscribed stones which stand in the woods and groves, and which commemorate the date when the plantations were formed. Evelyn refers to these date-bearing stones, and remarks, “The only instance I know of the like in our country.” The stones are referred to hereafter in describing the positions of some of the trees. Here and there, however, in the woods which these stones mark the birth of, there are standing larger and much older trees, which must have been planted long before any of the dates mentioned on the stones. The earliest date is that on the stone standing in the old heronry, near the Hawking Tower, built by the first Baron Spencer, and which bears the dates 1567-1568. Some of the trees stand so inconveniently for being photographed that nothing like justice has been done to their grand size and beautiful proportions, but the photographs in the accompanying album will give some idea of their shape, size, and beauty.! The first sixteen trees are growing in Althorp Park, and the remaining four in Harleston Park. The twenty trees give an average of 722 cubic feet each, which indicates their great age. 1The album is placed for the inspection of members in the Society’s library.—Eb. 84 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. The measurements of each tree are given in a tabulated form at the end of this report, so as to be more convenient for reference. 1. Ext, Eneuisu (Ulmus campestris). This fine tree is growing in the pleasure grounds, 150 yards on the east side of the mansion. It has a grand bole, girthing 13 feet 6 inches, where it divides into two ponderous stems, and these divide again, one at 12 feet and the other at 16 feet, and afterwards ramify into several smaller ones, which tower away to the great height of 117 feet, forming a top 94 feet in diameter. It girths 21 feet 2 inches at 3 feet from the ground, and contains a total of 924 cubic feet of timber. 2. CuestNuT, Horse (#sculus Hippocastanum). This is a beautiful tree, growing at the extreme north of the pleasure grounds, near the Wilderness. It is shut in very much by other trees, nevertheless it has a beautiful sweeping top 85 feet in diameter, with a bole of 10 feet in length, while-at 3 feet up it girths 13 feet 8 inches, and at 5 feet from the base 14 feet 10 inches, and contains a total of 533 cubic feet of timber. 3. Beecu (agus sylvatica). A fine young park tree, growing close to the drive leading to New Lodge, near Althorp Park Station. It has a bole 36 feet 6 inches in length, with a nice well-balanced top 98 feet in diameter. It girths at 3 feet up 14 feet 8 inches, and contains 375 cubic feet of timber. 4. Oak, ENGLISH (Quercus pedunculata). This is one of the grandest old ornamental park trees to be found anywhere, and one of the largest in the park. It is growing on the east side of the mansion-house, and 150 yards from the boundary wall of the pleasure grounds, standing in full view from the drive leading to the east lodge. This picturesque old oak has suffered very much by severe gales, losing two very large limbs at 33 feet from the ground. ‘The top is beginning to show signs of old age, OLD AND REMARKABLE TREES IN NORTHAMPTONSHIRE. 85 and some of the topmost limbs are quite dead. At 3 feet from the base it girths 26 feet, and contains a total of 947 cubic feet of timber. A stone standing near by bears the following :— This Wood was planted by Robert Lord Spencer in the Year of our Lord 1602-16038. 5. Erm, Encuisu (Ulmus campestris). A very remarkable tree, growing by the side of the carriage drive, and 200 yards from the front gates to Althorp House. The bole, at 12 feet from the base, divides into two very massive stems, and these separate into two each, one at 5 feet and the other at 8 feet; these again dividing into a number of smaller limbs, and towering to 105 feet high. It girths 23 feet 6 inches at 3 feet from the base, and contains 841 cubic feet of timber. 6. Cepar or Lepanon (Cedrus Liban). Growing on a plateau on the south front of the mansion, called the Highwood, stands this very old weather-beaten tree. The top has suffered very much by past gales and snowstorms, having lost at one time or another no less than twenty large limbs. This grand old monarch, before losing so many of its limbs, must have con- tained upwards of 1000 cubic feet of timber. Its girth at 3 feet from the base is 20 feet 10 inches, and at 5 feet, 22 feet 2 inches ; the top (what is left) has a diameter of 70 feet. Height of bole, 8 feet 6 inches, and the tree now contains 603 cubic feet of timber. 7. Wycu, or Scotcu Exim (Ulmus montana). This is a very fine wych elm. It is growing at the top end of Blue Bank Plantation, close to the gas-house, between the mansion and the kitchen garden. This tree deserves a more prominent place than where it is. It is very much shut in by other trees, and cannot be seen until one is quite close to it. It has a clear bole of 20 feet, with a well-balanced top, 94 feet in diameter. At 3 feet from the ground it girths 19 feet 8 inches, and contains a total of 487 feet of timber. 86 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. On a stone standing near an inscription reads— Planted by George John Earl Spencer K.G. in the Year MDCCC. to replace a grove of Ash fallen to decay. ‘*Uno. Arubro, non deficit Alter.” 8. Oak, EneiisH (Quercus pedunculata). A remarkably handsome park tree, growing on the side of a bank sloping to the north, towards the coach road leading to the west lodge. This grand specimen of an oak has one of the finest boles of any tree in the park, and growing as it does in a very prominent position, it shows itself off to great advantage. It is a very healthy- looking tree, and is adding to its girth yearly. The bole is 46 feet high, as straight as a gun-barrel, and it carries a nice well-balanced top of 87 feet 6 inches in diameter. At 3 feet up, it girths 21 feet 94 inches. The bole alone contains 836 cubic feet, and the whole tree 933 feet of timber. £100 was offered for this tree during the Crimean War. 9. OaK, ENGLISH (Quercus pedunculata). This is another good tree, growing 50 yards from No. 8. It is of quite a different type, having some very large limbs, growing out from near the base. At 33 feet up it divides into two, and then goes straight away to the height of 94 feet. It girths 19 feet 10 inches at 3 feet up, and contains 655 cubic feet of timber. 10. Oax, Eneisu (Quercus pedunculata). This tree, which stands in a line with No. 9, and 60 yards from it, is a beautiful specimen of a park tree. It has a healthy and vigorous-growing appearance, and will yet add a lot of girth to its already massive trunk. It has a grand, far-reaching, well-balanced top of 104 feet in diameter ; a bole of 33 feet in height. At 3 feet from the base it girths 22 feet, and contains 582 cubit feet of timber. 11. Oak, Eneisn (Quercus pedunculata), Another fine tree, standing 100 yards up the slope from the west lodge, and 60 yards from No. 10. It hasa bole 30 feet 6 inches OLD AND REMARKABLE TREES IN NORTHAMPTONSHIRE. 87 high, girths 19 feet } inch at 3 feet up, and contains 594 cubic feet of timber. 12. Cepar or Lepanon (Cedrus Libani). This is a beautiful vigorous-growing tree, standing in a hollow in the orchard, below the kitchen garden. It is nicely sheltered on all sides, and has a fine bole 32 feet high, as straight as an arrow, and up to 28 feet it has not a branch on it. This promises to make a tree of large dimensions. It girths at 3 feet from the ground 16 feet 11 inches, and contains 345 cubic feet of timber. 13. OaK, ENGLISH (Quercus pedunculata). In the deer park, on a bank sloping to the south, on the west side of the mansion and near to the church path, grows this remarkable ornamental park tree, just the type of what an old oak should be. It has a very massive bole, 23 feet 6 inches in girth, where it divides into two ponderous stems. ‘Fhese again separate, one at 8 feet and the other at 9 feet, and then ramify into a number of smaller ones, giving a top 91 feet in diameter. Its trunk girths 21 feet 3 inches at 3 feet from the base; and the tree altogether contains the very large total of 1016 cubic feet of timber. Near this tree stands a stone with the following inscription :— This Wood was planted By Sir William Spencer, Knight of the Bath, in the Year of our Lord 1624, **Up & be doing and God will prosper.” 14. Oak, ENGLISH (Quercus pedunculata). This beautiful young oak is growing in the heronry at the top end of Sir John’s Wood, in the extreme north of the Deer Park. It has a fine, straight, clear bole, 64 feet in length, and a vigorous- growing top, the whole rising to a height of 98 feet. This will doubtless make a very large tree, as it is adding to its girth at a rapid rate. At 3 feet from the base its girth is 12 feet 10 inches, and it contains 469 cubic feet of timber. A stone in the centre of the wood, and 100 yards from this tree, reads— 88 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. This Wood was planted By Sir John Spencer, Knight, Father of Robert Lord Spencer in the Year of our Lord 1589. Standing in the old heronry adjoining this wood, and near the Hawking Tower in Althorp Park, a stone bears the following inscription :— This Wood was planted By Sir John Spencer Grandfather of Robert Lord Spencer in the Year of our Lord 1567-1568. 15, Lime (Tilia Europea). A remarkably fine specimen of a park tree, growing on a bank sloping to the north, and 270 yards south of the east entrance to Althorp Park. This is the upper tree of three limes growing in a line at 16 yards apart on rather shallow soil, a quarry, 25 yards from the trunk of the tree, showing the stone to be close to the surface of the ground. A finer specimen of a park tree than this is it would be hard to find. Ata height of 10 feet 6 inches it divides into six large limbs, spreading out and giving it a diameter of top of 90 feet 6 inches, the lower branches sweeping all round close to the ground. It girths 17 feet 7 inches at 3 feet from the ground, and has a total of 575 cubic feet of timber. In the Ice-House Plantation near to this tree there is a stone bearing the following inscription :— Planted by George John, Earl Spencer, K.G., in the Year M.D.CCXCVIII. **Seris Factura Nepotibus Umbram.” 16. Asu (Fraxinus excelsior). This remarkably grand tree is growing on the south side of the mansion, and close to the boundary wall dividing Althorp and Harleston Parks. This gigantic specimen of an ash has a bole 36 feet high, with some immense limbs spreading out on all sides, and gives a diameter of top of 92 feet. The trunk girths 17 feet 6 inches at 3 feet up; and the tree altogether contains 809 cubic feet of timber, OLD AND REMARKABLE TREES IN NORTHAMPTONSHIRE. 89 17. Exo, Enexutsu (Ulmus campestris). On the west of Harleston House, and just outside the flower garden in the park, grows this very fine elm. At 20 feet high it lost a very large limb in the gale of October 14, 1881. It has a good bole to 50 feet 6 inches, and towers to the height of 110 feet. At 3 feet from the ground it girths 20 feet, and contains 715 feet of timber. 18. SpanisH CuHeEstNuT (Castanea vesca). On the north side of Harleston House, and 60 yards from the kitchen garden, grows this grand type of an old ornamental park tree. It has a fine straight bole 20 feet high, dividing here into two enormous stems, these branching out again at intervals, and towering to the height of 90 feet. It has a beautiful well-balanced top of 85 feet diameter. It girths 26 feet 3 inches at 3 feet from the base, and contains the magnificent total of 1220 cubic feet of timber. 19. Spanisn CHESTNUT (Castanea vesca). At 25 yards away, and to the east of No. 18, stands this grand tree, and although somewhat dwarfed by its near neighbour, yet it contains 893 cubic feet of timber. It has a bole of 27 feet in length. At 3 feet from the base it girths 23 feet 4 inches, and has a spread of top 86 feet 6 inches in diameter. 20. Spanish CHestnut (Castanea vesca). This is another remarkable old ornamental Spanish chestnut, grow- ing 140 yards north of No. 19, on a rising bank facing the east, in an exposed situation. At 3 feet from the base it girths 24 feet 34 inches. This tree has lost some immense arms; the largest broke off 5 feet from the trunk at 15 feet up in the gale of October 14, 1881. This arm girths at 3 feet from the bole 9 feet 10 inches. At 12 feet from the ground an enormous limb grows out, curving its way upwards to 65 feet, and having quite an imposing appearance. At 3 feet from the bole this limb girths 10 feet 11 inches, the whole tree containing 924 cubic feet of timber. 90 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY.

The Formation of Plantations. By A. C. Forses, Assistant Forester, Lintmill, Cullen. Introduction. The great length of time which must ensue before any adequate return can be expected from newly-formed plantations in this country probably accounts for a great deal of the apathy and indifference with which the majority of landed proprietors look upon their waste ground and worn-out woodlands. Even the majority of those who do plant are probably actuated more by a desire to beautify their estates, provide shelter for game or against wind, and generally add to the value of their property, than with any definite idea that the money expended in planting and main- tenance will ever be repaid with interest. Although planting with the former objects in view is free from any objection from an esthetic standpoint, or when considered by themselves, yet it will be admitted by every one versed in rural economy that planting without due consideration of the profit and loss principle does not produce such satisfactory results as should be desired. Just as we find the careful and intelligent farmer, who carries on his business on strictly economical lines, more permanently benefiting himself and the country generally than the gentleman farmer who sinks hundreds of pounds in high-class and extrava- gant farming, so we can easily see that the proprietor who never throws money away in planting ground with unsuitable plants, or which is unsuitable for planting at all, will be more likely to permanently increase the value of his property, benefit the local population, and give a better appearance to his estate generally, than another who merely aims at producing game cover, or a mass of foliage which can only be called pleasing when viewed from a distance. In support of these ideas, we have only to visit such estates as those belonging to the Dukes of Athole, Portland, Bedford, Lords Mansfield, Seafield, Lovat, and many others in the United King- dom, and we find that their most attractive features, prosperous appearance, and influence on the local trade and population, are largely due to the careful and practical manner in which their woods have been managed for many years. 92 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. The explanation of these facts must be obvious to all, when we consider that a healthy plantation simply means a mass of healthy trees. A man needs little or no knowledge of forestry to enable him to discriminate between a thriving and healthy tree and a diseased and stunted one; and every true artist will admire the former before the latter, because the healthy tree is the typical production of the great artist herself—Nature, the source of all art. Now every practical forester knows that a healthy and vigorous growth can only be insured by the careful selection of those plants which are thoroughly well adapted to soil, climate, and situation. Although it would perhaps be going too far to say that indigenous plants can alone supply what is required in this respect, yet when we consider the various diseases and climatic affections to which introduced trees are subject in this country, coupled with the fact that they rarely retain their timber qualities when removed from their native habitat, we may safely infer that if we want to see a healthy and vigorous growth main- tained throughout the lifetime of our plantations, we must content ourselves with those species which nature has provided with a constitution strong enough to withstand our changeable tempera- ture and uncertain climate, and leave recent introductions outside the bulk of our woods until careful experiments in various soils and situations have determined their particular requirements in these respects. And with regard to the third point, viz., their relation to local industries, the importance of healthy woods is made still clearer, We usually find that any industry which owes its existence to the manufacture of articles of commerce from or out of the raw material, is located in the neighbourhood from which the raw material is obtained. The reason for this is obvious, and needs no explanation, Now, although the industries connected with woods in this country are comparatively unimportant when considered individually, yet when taken collectively we find that they occupy a more important place in regard to the prosperity of the country than would at first sight appear. It is true that woods neither bring in money nor employ much labour for the greater part of their growth, but this is exactly the period in which they exercise the most beneficial effects on the adjoining agricultural lands. Their relation to climate, rain-fall, water- supply, ete., is also considerable, but which can only be merely referred to here. But during their formation and earlier stages, THE FORMATION OF PLANTATIONS. 93 and the final cutting and disposal of the timber, they give employment to many hands, and at a time of the year when employment is often much needed. The formation of a plantation necessitates the performance of various operations in the way of draining, fencing, planting, etc., all of which give work to a large number of men, and also benefit more or less directly various tradesmen, railway companies, and others, according to the extent of the work. At the final cutting, again, in addition to the labour required for that operation, the manufacture and removal of the produce gives considerable employment to a large number. Woods also give rise to many minor industries in their immediate vicinity, such as hurdle-making, broom, clog, bobbin, and chair making, charcoal-burning, etc., while the more recent use of wood in the manufacture of paper may cause early thinnings to become of greater value than they have hitherto been. We thus see that woods of any kind play an important part in the prosperity of a rural district; but it is only when the true principles of forestry have been observed in their management that the greatest benefits derivable from plantations are obtained. It is a recognised fact that only timber of good quality and clean growth will command a fair price in the market; and if home-grown timber lacks these conditions, the merchant supplies himself with a better class of timber imported from abroad, thereby sending out of the country the money which might have been circulated within it. The question as to how long this importation of foreign timber may continue at its present rate is exercising the minds of many of our political economists of the present day, but it appears to be generally admitted by those best qualified to give an opinion, that if we should ever require to turn our own woods to account in the event of a timber famine, a more scientific and economical system of management will have to be adopted than has hitherto existed in this country. Laying off the Boundaries. When it has been definitely decided to form a plantation, the marking off of the boundaries should be the first operation to be performed. In planting old agricultural land, the existing size and shape of the fields are usually retained, except, perhaps, where the outlines are too formal or irregular, and require rounding off or otherwise modifying to suit the taste or requirements of the 94 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY, proprietor. When formed solely for the purpose of giving shelter to adjacent lands, however, it is sometimes necessary to lay off fresh boundaries altogether, in order to break as much of the wind as possible, and give shelter to a larger area, As winds usually acquire their objectionable character from the surface over which they have previously passed, whether snow-covered mountains, hot deserts, or wide oceans, it is evident that the wind most dreaded in one locality may be perfectly harmless in another, although coming from the same quarter of the compass ; therefore no general rule can be laid down as to the particular direction in which a shelter-belt should extend, all depending upon the direction from which the wind comes that it is desired to break. The shape of the belt must depend a great deal upon the extent of ground it is intended to shelter, and the conformation of the ground. When it is intended to give thorough shelter to a limited area, that of an acute angle is probably the best, with the apex presented to the wind. When given such a shape it has a greater tendency to divert the current of air in two directions, one along each side of the belt respectively ; and it also gives more efficient shelter to the ground immediately to the leeward of the belt, by protecting the two sides nearly parallel to the direction of the wind, forming a cove or recess, an invaluable situation for pasturing cattle. When it is desired to shelter a larger area without increasing the size of the belt, the angle may be increased until it results in nearly a straight line, the convex side of which should always be presented to the wind, otherwise it would have a tendency to concentrate the force of the wind into the corner formed by the junction of the two sides, thereby increasing its force at that particular spot. The length of such a belt is inde- finite, according to the requirements and extent of the ground to be sheltered, but the breadth at the point of impact should never be less than from one to two hundred yards if it is intended to produce timber, and either retaining that breadth throughout, or gradually decreasing towards the leeward extremities. In laying off plantation boundaries which are intended for the production of timber, we have to be guided by different principles. Here we have to consider how best to prevent strong or prevailing winds from injuriously affecting the health and growth of the trees and uprooting them after a severe frost or heavy rain, both of which loosen the ground and render the trees more liable to be overturned, So long as a plantation remains intact, and is not THE FORMATION OF PLANTATIONS. 95 weakened by injudicious thinning, we rarely find that winds do much damage in the way of uprooting, but that they have a great influence on the health and growth of the trees is a well-known fact. Indeed, in wind-swept situations we have only to notice the shape of individual trees that stand alone to ascertain from which direction the prevailing winds come. The windward side of such trees is rounded off as if trimmed with a knife, while the branches on the opposite side are longer and more vigorous. This is more especially noticeable near the sea, where the wind is laden with salt from the ocean, and which few trees can withstand with impunity. Seeing that the wind has so much effect on the growth of trees in exposed situations, it is evident that the smaller the surface presented to the wind the less will its influence be felt. To secure this desideratum, it is clear that we must follow to a certain extent the plan adopted in the case of shelter-belts, and by presenting a barrier to the prevailing wind endeavour to shelter the bulk of the plantation in somewhat the same way as the fields were sheltered in the former case. We notice that the trees on the extreme edge of a plantation exposed to strong winds are always the smallest and most stunted, in consequence of having to stand the full brunt of the blast. The second row back is less affected than the first, owing to the shelter afforded them by the latter, and we find them a foot or two higher, and with their tops leaning away from the wind, The next row presents a similar appearance, but taller than the second ; and so we find the trees gradually getting taller as we penetrate deeper into the wood. It is evident, from the inclined plane presented by the tops of the trees collectively, that the wind, when coming in contact with the edge of the plantation, is forced upwards until it reaches the average level of the tree-tops (where it meets with no opposition to its horizontal course), and only falls to its former level again when it has passed the limits of the plantation. To satisfy ourselves on this point we have only to stand on the leeward side of a wood in windy weather, and go long as we are under the shelter of the trees we feel little or nothing of the force of the wind, but the farther we retreat from the wood the more we experience its effects, until we get to such a distance from it as to render its sheltering influence altogether imperceptible. Such being the case then, it is evident that when once forced to the top of a mass of wood, the wind cannot again fall until an opening occurs in the wood itself, or it reaches the Open country. 96 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. In the case of a plantation on a hill-side, however, which faces the wind, this forcing upwards is continuous until it reaches the summit, and each tree being higher than the one immediately standing below it, owing to the rise of the ground, the wind has almost the same effect on the whole of the plantation as it had on the edges of the one standing on level ground. In forming a plantation on a hill-side, then, we cannot protect the trees from the wind by giving the outlines any particular shape, but merely prevent it from acting on individual trees as much as possible by keeping them as close, and the whole of the plantation as perfect and free from gaps as possible. But on flat ground we can do something to lessen the effect of the wind by presenting as small a surface to the point from which it comes as possible. The most effectual method we could adopt would perhaps be that of giving the plantation an oblong or conical outline, with the shorter sides or the apex facing the wind; but such outlines would be too lengthy, and increase the expense of fencing, while they would probably be considered too formal for making a pleasing feature in the landscape. Perhaps the one most likely to suit all conditions is that of a triangle, with the apex facing the wind, as in the case of the shelter-belts, and for the same reasons. Of course gales do not always blow from the same point of the compass, and therefore we should guard against them as much as possible on all sides; but as this is a matter more closely connected with planting and thinning, we think the prevailing winds should receive most consideration when laying off a plantation intended for the production of timber, as they affect the growth and health of the trees to a greater extent than the others. To endeavour to make the boundaries as short as possible, and the avoidance of unnecessary curves and corners, are import- ant points where economy is aimed at, as the fencing of the ground is always an expensive item, especially when compound interest has to be charged for a number of years on the original outlay. Generally speaking, the size and shape of plantations should conform or agree as much as possible with the surrounding country. Fencing. The expense incurred in fencing and draining ground before planting can be proceeded with probably deters many proprietors from planting more of their waste ground than they do at present. THE FORMATION OF PLANTATIONS. 97 Were it not for the necessity of fencing, there is little doubt that many odd corners and waste patches of ground to be found on every estate would be utilised in growing timber, but owing to the fact that such pieces of ground are usually of a very irregular shape (generally consisting of narrow strips by the roadside, or small ravines), the length of fencing that would be required would be out of all proportion to the area enclosed, and therefore we rarely find such ground planted unless for shelter. In forming extensive plantations, however, the larger the area enclosed the smaller the cost per acre, providing judgment is exercised in laying off the boundaries ; but even then it always forms one of the most expensive items, and should be done at as little cost as is consistent with durability. In planting extensive tracts of moorland or hill-sides which are not depastured with sheep or cattle, fencing may sometimes be dispensed with altogether, or only carried out on the sides liable to encroachment ; but generally speaking, it is rarely safe to omit taking full precautions against any possible damage to the young plants, as any such omission may result in serious injury to the plantation. Plantations to be formed in the midst of agricultural or grazing ground must be thoroughly and efficiently fenced on all sides, and the most economical fence for general plantation purposes is probably the turf dyke, surmounted by a low post and wire fence. The dyke should be 3 feet high (at the base of which a ditch should run 2 feet deep by 3 feet wide at top), and should be substantially formed of sods or turfs containing as little organic matter as possible, the outside face being made almost perpendi- cular, the inner sloping away gradualiy. It must be allowed to settle down properly before the wire fence is erected, or the posts will not take a firm hold of the ground, and when the fence is erected it should not stand nearer the edge of the dyke than 12 or 18 inches. The posts should be larch, 45 feet long, and not less than 2 inches in diameter at the small end, and should stand 24 feet above the top of the dyke. As the posts decay rapidly in dry dykes, the wooden straining posts should be replaced by iron pillars erected every two or three hundred yards in the straight parts of the fence, and at any corner or bend where required. This will increase the cost of the fence at the outset, but will prove the most economical in the long run, as the iron pillars will last for many years if kept varnished or painted, VOL. XIII. PART I. G 95 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. Three No. 7 wires will be sufficient, fixed to the posts by staples, and strained by means of brackets fixed on the iron pillars, double brackets being attached to every other pillar for that purpose. The larch posts should be soaked in creosote or tar after they are thoroughly dry before being used, as when so treated they will last considerably longer than unprepared ones, A fence of this kind, dyke included, will cost from 8d. to 1s. per yard, and if well put up the expense of maintaining it will be comparatively trifling, as after a few years decayed posts may be renewed from the thinnings of the plantation, thus avoiding the necessity of carting from a distance. Should the soil be suitable, and the situation favourable to its growth, a thorn hedge may be planted on the inside of the fence, and, if properly attended to, will be sufficiently strong to take the place of the latter by the time the posts have decayed; but all overhanging branches must be kept cut back, or it will become weak and patchy. In such a case the iron pillars may be dispensed with, and wooden strainers used instead. Various other kinds of fences are in use throughout the country, such as stone dykes, slate, posts, and hoop-iron, and hedges of all descriptions ; but the style most commendable for a plantation depends upon the locality in which it is erected, proximity and cost of materials, skill possessed by the workmen employed, and whether intended to be permanent or only temporary; and there- fore all these particulars must be taken into consideration before any description of a fence can be recommended in preference to another. Draining. In no operation connected with the formation of plantations is more judgment necessary than in draining, for if imperfectly or carelessly done, it often fails to produce any of the good results expected from it, while one drain in the right place may be more effectual than a dozen inthe wrong. The first thing to be ascer- tained is the extent of ground which really requires draining, for it is seldom that the entire surface of an extensive piece of ground is too wet for the healthy growth of trees, and therefore all unnecessary draining should be avoided as much as possible. The natural vegetation affords a pretty good indication of the nature of the surface soil in this respect, and should be carefully noted. It will generally be found that where the natural vegetation is healthy THE FORMATION OF PLANTATIONS. 99 and flourishing, the soil itself is in a fairly good condition, both chemically and mechanically, or at least so far as uncultivated ground can be expected to be. But the natural vegetation usually consists of plants best fitted to exist under those conditions of soil and climate in which they are found, and therefore the fact that the indigenous plants are thriving is no criterion by which we can prove that the trees we wish to plant there will thrive too, unless we know that the latter thrive under the same conditions as the former. If we know this, we can assume that the ground is in a comparatively fit condition for the plants we wish to intro- duce, and draining is therefore unnecessary, but where the vegetation indicates a condition of soil known to be unsuitable to the plants we wish to stock the ground with, then we must endeavour to remedy this unfavourable condition if possible. On the other hand, when the soil is in a sour, unhealthy condi- tion, the vegetation invariably indicates it. If we notice the heather growing on a wet piece of moorland, with an underlying stratum of moor-pan, we usually find it stunted, sickly, and covered with lichens, so that we come to the conclusion that something is necessary to put it in a more satisfactory state, and the removal of the superfluous moisture will be the first consideration. The first point to be considered in commencing to drain, is the outlet which will have to carry off the whole of the discharge from the drains connected with it, and if possible this should always lead into a natural water-course or burn, as all further trouble is thereby avoided in getting rid of the water, providing the natural channel is sufficiently wide and deep to carry off the additional water. It is not necessary for all the drains to have the same outlet, as in hilly and unduiating ground this would be practically impossible ; but on flat ground, or where the fall or slope is very slight, the lowest part of the ground must be the point for the outlet, which should be carefully ascertained by means of the theodolite and levelling rods, as guess-work is often very risky in regard to this point. The outlet having been decided on, a main drain (or several, if required) should be cut from it to the farthest extremity of the ground that requires draining, giving it a few inches more depth than the sub-mains running into it. The main drain, and all others in fact, should be perfectly straight if the surface of the ground permits, but if not, it should take such a course as will ensure a gradual and uniform fall from its com- mencement to the outlet, which must depend upon the slope of 100 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. the ground, but from 1 in 150 to 1 in 200 is quite sufficient to ensure a steady flow, which is less liable to injure the sides of the drain than a more rapid fall. The depth should be from 3 to 4 feet according to the nature of the soil, the depth it is intended to make the sub-mains and laterals, and the quantity of water it will be likely to receive. The sides of the drain should have a slope of 45° if the soil is at all loose or friable, but less than that will be sufficient in clay or adhesive soil, and it should have a width of 1 foot at the bottom, the sides being neatly dressed, and made firm with the back of the spade. The sub-mains should be cut on the same principle as the main, but will not require to be so deep or wide, their dimensions being in proportion to the number of laterals running into them, and the state of the ground. The fall for these should be slightly greater than that of the mains, as their efficiency depends on their carrying off the water rapidly and thoroughly, and they are more liable to get choked with leaves and débris than the larger drains. Two drains from opposite sides of the main should never run into it at the same point, as when the flow is at all rapid, leaves and rubbish are brought down and deposited at this point, and tend to prevent the free flow of the water ; but a slight curve should be given them just before they enter the main, where there is any probability of a rapid flow, in order to prevent the water from washing into the opposite bank. The method of draining the main portion of the ground by means of the lateral drains, must depend upon the cause of wetness and the nature of the soil. When the superfluous moisture is caused by springs, thrown out by an impervious substratum, and spreading over the surface of the ground, a deep drain should be cut along the line of the outbreak (which can easily be seen by the state of the ground), so as to catch and carry away the water before it has spread over the surface. This will sometimes succeed in drying the ground below the drain, but much will depend upon the depth and arrangement of the strata through which the drain is cut. Sometimes the moisture is due to the impervious nature of the surface soil, such as clay or moor-pan, and should this rest on a porous bottom a few deep drains reaching to the porous bed will carry off much of the water, and render a main unnecessary, This is an important consideration on flat ground, where there is a difficulty in getting a proper fall, and should always be taken advantage of when possible. When the wetness is due to the THE FORMATION OF PLANTATIONS. 101 retentive nature of the ground, as in clay soils or peat bog, a thorough system of lateral drains must be carried out. These are usually placed at the distance of from 20 to 30 feet apart, and should be cut with their sides perpendicular, as they are thus less likely to be beaten down by heavy rains, which fill up the inter- stices of the soil, and prevent the water from percolating through them freely. Their depth is usually about 18 inches to 2 feet, according to the requirements of the intended crop, coniferous trees requiring less depth of soil than hardwoods, as their roots do not penetrate so far into the soil as those of the latter. Where the ground slopes, the laterals should be cut at a more or less acute angle with the mains, in order to secure a proper fall, but the nearer they approach to a right angle with the main, the greater will be the area drained in proportion to their length. As before stated, all unnecessary drains should be avoided, while in extra wet places they may be cut closer than the usual distance, just as they may be required. In draining undulating ground, it is sometimes impossible to carry off the water by means of a main without going to great expense in cutting a drain far deeper than the average. Such a case occurs where the ground slopes from all sides, and forms a hollow, when, to carry off the water, a drain would have to be cut through the surrounding ground until a lower level was reached. lt is obvious that the expense incurred in doing this would be out of all proportion to the return expected, and therefore it would be more economical to run all the drains into the hollow, and allow it to form a pool. Should, however, a porous stratum exist within a reasonable distance of the surface of the hollow, a hole cut down to it will carry off the water before it has time to accumulate, On very flat ground, where a fall cannot be obtained, or where it is so slight as to be practically imperceptible, the best thing to do is to cut deep ditches at regular intervals, in which much of the water will collect, and leave a sufficient depth of drained soil to enable certain species of trees to succeed fairly well. Such are the principal and most frequent cases which occur in draining plantation ground, but exceptional ones may arise which will require special methods of treatment, but which it is not necessary to describe here. 102 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. ° Preparation of the Ground. It seldom happens that waste ground can be planted without some preparatory operations being found necessary to secure a favourable start for the young plants. The soil may need break- ing up where too hard, or the natural vegetation require removing, or both of these operations may be necessary before planting can be proceeded with. On heathy ground, moor-pan is the most frequent obstacle to the healthy growth of trees, and it must be broken up before they are planted. Moor-pan occurs in gravelly soils containing a large quantity of oxide of iron, which, when in combination with water, forms a hard solid stratum, through which tree roots are unable to penetrate, and being impervious to rain, it often causes swamps. Moor-pan is usually broken up by means of an imple- ment called a foot-pick, which is familiar to every forester in the north. It must be driven in under the pan if possible, as little good will be effected unless it is thoroughly broken up. This should be done a considerable time before planting is performed, so that the atmosphere may act upon and sweeten the soil, and decompose any inert matter contained in it. Hard: gravelly soils are also benefited by the above operation, and the extra expense incurred is generally compensated for by the growth and vigour of the plants compared with those planted in unprepared ground. When pitting is intended, which is usually adapted for hard- woods, the pits may be opened six months or more before they receive the plants, as the soil is thus pulverised by frost, and chemically acted upon by the atmosphere. In wet soils, however, they are apt to fill with water, and in such cases are better left until the time for planting arrives. Of natural vegetation, whin or furze is probably the most trouble- some to keep down until the plants are out of all danger of being smothered. They should be burnt, and the big stumps grubbed out as low as possible, as it is the growth from these old stumps that proves the most troublesome to deal with, and after the plants are in, burning is out of the question. Some recommend cutting out lines through the whins, and trenching the soil. This would give the plants a better chance of succeeding and growing out of danger ; but in badly-infested places they would still require to be kept down by cutting. Burning should be done about the middle ot June, after the seeds have germinated, and before the pods THE FORMATION OF PLANTATIONS, 103 are ripe on the old plants ; and when done about this time it leaves the roots ina weaker condition than when done in winter. Long, rank heather will also require burning off, and this should be done three or four years before planting, if possible, as short heather is beneficial to the young plants by protecting them from the sun and frost. Long grass must also be removed at or before the time of planting, where it has formed a close matted turf. Such turf intercepts and appropriates both dew and gentle rain, and none but the heaviest rains penetrate it, therefore plants inserted in it by notching invariably die in the event of a dry summer suc- ceeding the planting season, especially in light dry soils. This is best removed some time before planting, so that the soil may be well soaked and softened by rain. The turf should be entirely removed with a spade, leaving a bare space about 9 inches square on the site intended for the plant, and if the soil is broken up at the same time, so much the better. On dry, heathy ground, a dry inflammable sort of peat often gathers on the surface, which is very unfavourable for nourishing most plants, and in which trees never thrive until their roots have reached the soil beneath. Where such exists, it must be removed in the same way as the turf, unless it is too deep to be removed in that way, when the subsoil should be brought to the surface, and spread over the ground to a depth of six inches or so, which will be sufficient to grow Scots fir and birch. Although it may be too expensive a process for carrying out on a large scale, yet it is not more so than planting such ground without any pre- paration, with the result that the plants never grow into anything larger than a stunted bush. Peat of the same description, but wet instead of dry, is equally unfavourable to healthy growth, and must be treated in the same way, providing, of course, that the subsoil is capable of growing timber, as if not, the ground had better remain unplanted. Brambles, thorns, brackens, and all other rubbish must be cut, and cleared off the ground before planting commence, so that nothing may interfere with the pro- gress of the work. Choice of Plants. This is one of the most important and difficult questions which the forester has to decide when forming a plantation, for although comparatively easy to choose species that will grow and make cover, 104 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. yet when the problem of producing the most valuable crop of timber in the least possible time has to be solved, it is one that requires considerable foresight and judgment. To ascertain beforehand the exact capabilities of the soil and situation is nearly impossible, although in many cases it may be done with some degree of accuracy, and the only way it can be accomplished, apart from chance, is by carefully noting the soil and situation of existing plantations, and their condition as to health and growth. Altitude, climate, and exposure have probably more to do with the growth of trees than even soil itself (although the latter has a great influence on the quality of the timber), therefore the situation of the ground in regard to the first-named conditions must receive due consideration. As before pointed out, indigenous trees are more likely to turn out successfully from an all-round point of view, and give better results than those introduced from higher or lower latitudes, or from countries possessing different climatic conditions to those of our British Isles. It is true that exceptions to this rule may be found in many healthy and thriving plantations, composed of larch, spruce, and other introduced trees, but these are only found where the situation, soil, etc., are excep- tionally favourable to their growth, and in such cases no objection can be found to their having been planted. But the miserable appearance presented by so many plantations of larch in different parts of the country proves the folly of planting these trees indis- criminately, and without duly considering the conditions requisite to bring them to maturity. Mere volume of wood, too, is often taken as the standard by which the timber qualities of different trees are compared with one another, but quality should be synonymous with strength and durability, and unless the timber possesses those qualifications, its market value will be compara- tively small, and most of our introduced Conifer obtain their rapid growth at the expense of quality of timber, and therefore nullify any advantage they might otherwise gain over indigenous trees. Considerable caution should be exercised, therefore, before foreign introductions are extensively planted, in order to see that the conditions under which they will have to exist are such as are known to be favourable to their healthy growth and the production of good timber. Deciduous trees (with the exception of birch, alder, and aspen) should never be planted in any situation in which they are known THE FORMATION OF PLANTATIONS, 105 to grow slowly and unprofitably, as their timber value is usually in direct proportion to the rapidity of their growth, ceteris paribus. Coniferous trees, on the other hand, generally produce better timber when their growth has been slow, and are therefore better adapted for planting at high altitudes, although they take longer time to come to maturity. In this country (Scotland) timber of any kind can hardly be profitably grown over 1500 feet above sea-level, and, in the vicinity of the sea, that altitude is probably too great. Much depends, however, upon the latitude ; the nearer the equator the greater the altitude at which plants will grow. Climate is perhaps the most important factor in vegetable growth, for the elements of cold, heat, light, and moisture come under its head. More especially must it be considered in relation to all introductions from other countries, for it is the only important distinction which exists between different countries, and therefore powerfully affects plant life when moved from its native habitat. Owing to the insular position of Great Britain, it enjoys a warmer and more temperate climate than many countries which lie between the same degrees of latitude; but although it possesses the advantage of being usually free from extremes of cold and heat, it has the disadvantage of being very variable, especially during the spring months, when vegetation is very susceptible of atmospheric influence. In consequence of this, introductions from countries possessing more regular and equable climates than ours are often excited into growth by a spell of mild weather during March and April, and in the event of this being succeeded by a few days of cutting wind, or frosty nights, the effect on such plants is very injurious, and often engenders disease and unhealthy growth. This is frequently noticeable in the larch and silver fir, as shown by the unhealthy condition of their foliage, and the consequent attacks of aphides and other insects which generally accompany a weak and sickly growth. To prevent the result of this excitability as much ag possible, such trees should be planted in situations where the variations of temperature are felt as little as possible, such as on slopes facing the north, cool soils, or in any other situations where the plants would be less likely to start early into growth, Duration and intensity of sunlight also exercise a great influence on tree growth, especially in regard to the proper ripening of the wood. Trees like the larch, which continue growing late into autumn, cannot fail to be injuriously affected by a cold wet 106 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. period during the months of September and October, as the young growths do not ripen properly, and are often destroyed by frost in the event of a hard winter succeeding such an autumn. Although rot in the wood of the larch is usually attributed to the condition of the soil, yet it is probable that improperly ripened wood may have equally as much to do with the disease ; while it appears to be almost a certainty that the blister so common in this tree is the effect of the same cause. The requirements of different species in respect to light should be well understood by the planter and thinner, as the mixing and mode of planting and thinning a plantation in a judicious manner depends a good deal on an accurate knowledge of this subject. Trees which require a considerable quantity of light for the development of their branches do best when planted by them- selves in masses, as if mixed with shade-bearing trees, the latter would be apt to crowd them out if both classes were of the same age. In growing oak on dry soils, however, its own shade is sometimes insufficient to keep down weeds and rubbish, which impoverish the soil by appropriating much of its plant food, and in order to prevent this, beech is sometimes recommended for planting under the oaks, when the latter have reached a height of 50 or 60 feet, and have received their final thinning, which has the effect of increasing the leaf canopy and enriching the soil. The same system might be adopted in regard to ash, as although the soil suitable for growing ash is of a damp nature, yet a greater crop of wood might be obtained from the ground than would be the case if the space beneath the trees remained unoccupied. Spruce or silver fir, however, should be substituted in place of beech, as the latter is of little value when small, and ash coming to maturity far quicker than oak, would not allow time for it to grow to any size. Oak, ash, larch, and Scots fir are the principal light-demanding trees; while beech, hornbeam, silver fir, and spruce grow well under shade. The annual rainfall of the district, considered in connection with the character of the soil, should influence our choice of plants to a certain extent. A porous, sandy soil is usually better suited for growing trees in a district with a heavy rainfall, than one of a cold retentive nature. In a moist atmosphere evaporation from the leaves is reduced to a minimum, and therefore the quantity of moisture required from the soil is comparatively small, while dry soils are more favourable to the development of fibrous roots THE FORMATION OF PLANTATIONS. 107 than heavy ones, providing sufficient moisture is present to hold in solution the mineral matter required by the plant. The amount of frost which may be expected in any situation must be anticipated before planting tender species, especially those which do not ripen their wood thoroughly. The young growths of larch and oak are often cut back by frost, although the latter tree is less likely to be permanently disfigured by the loss of a leader than the former, owing to its stem ultimately becoming straight by the way in which its annual layers of wood are deposited. For exposed situations those plants should be selected which are known to withstand strong winds with impunity, and, at the same time, those avoided which become crooked and stunted in such situations. In situations near the sea, the saline-breeze has to be reckoned with, which greatly reduces the list of suitable trees. The most suitable trees for inland exposure are the Austrian pine, mountain pine, Scots fir, aspen, willow, sycamore, mountain ash, birch, etc. All species will grow when in masses, but the above-named should occupy the most exposed places, according to the soil and situation for which they are respectively adapted. Spruce and silver fir stand the wind well as far as growth is concerned, but the former is easily overturned by gales, and should never be planted on the margins of plantations. A belt of copse-wood or bushy growing trees, such as the mountain pine, mountain ash, hazel, thorn, birch, ete., planted round the margins, would be beneficial in exposed situations by preventing the wind from sweeping in under the taller trees, drying the surface, and carrying away fallen leaves, which latter are of great importance in poor dry soils. As growing timber near the sea is almost an impossibility, plantations formed near it are usually only intended for shelter, and therefore such species should be selected as will grow best, independent of their timber qualities. The sea buckthorn is an invaluable plant for the exposed margin of such plantations, and if hedges or lines of it were planted two or three years before the other plants were put in, it would doubtless be found a great aid in giving them a fair start, which is the most difficult part in the formation of these plantations, The most suitable plants are the deciduous trees enumerated above, and the following conifers :— the Austrian, mountain, and Corsican pines, and, if slightly sheltered, the Scots fir. Although it is almost impossible to accurately predict the trees 108 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. which will succeed best in any particular soil, yet a careful examination of the latter is indispensable when making a judicious choice of plants. The natural vegetation is usually a pretty good in- dication of the character of the surface soil, but is not always a safe criterion by which to judge the subsoil. Thomson’s ‘ Gardener’s Assistant” (p. 38) gives the following list of plants that have been observed to grow naturally on different descriptions of soils :—** Argillaceous—Tussilago Farfara, Potentilla anserina, P. argentea, Orobus tuberosus, Lotus major.

Fertility—Cnicus lanceolatus, Urtica dioica, Stellarva media, Dactylis glomerata, Poa trivialis. Cold subsoil—Of this, Equisetum arvense is peculiarly indicative.” When it is intended to plant shallow-rooting coniferous trees only, such as Scots fir, larch, and spruce, the character of the subsoil is of less consequence, as their roots rarely penetrate to a greater depth than 18 inches or 2 feet ; but hardwoods, especially oak and ash, send their roots deep into the ground, and the subsoil has a greater influence on their growth than on the growth of the former. In many cases the surface soil is formed by the disintegration of the rock upon which it lies, and therefore the character of the subsoil can be easily seen; but in alluvial and diluvial deposits it is often of a totally different character, gravel and clay frequently lying in juxtaposition. All such formations, therefore, should be examined by digging holes here and there THE FORMATION OF PLANTATIONS, 109 over the ground, and the subsoil noted down. The soil is rarely found to be of the same nature over any large area, and therefore the species should be distributed so as to suit the different. soils, according to the elevation, exposure, etc. All soils may be roughly divided into three classes, viz.— argillaceous, arenaceous, and calcareous, all presenting fertile and infertile examples, according to their mechanical condition, com- position, and depth, and an attempt will be made.to briefly show the most suitable trees for each class. Argillaceous.—These consist principally of silicate of alumina, and vary from pure clay to strong loam. These soils are especially adapted for growing hardwoods, such as oak, ash, hornbeam, poplar, etc., and all trees that delight in a strong damp soil, On the stiffer and wetter kinds the ash does not succeed so well as the other three. When resting on a bed of sand or gravel, they suit ash and sycamore better than most soils, and the addition of calcareous matter makes a soil highly favourable to ash and spruce. A mixture of clay and gravel suits spruce, silver fir, and larch, providing the drainage is good; but, generally speaking, these soils are not suitable for growing coniferous timber, as although the trees grow rapidly when young, they are usually short-lived, and rarely produce good quality of timber, being too coarse and soft through rapid growth. Arenaceous.—Silica forms the chief constituent of these soils, and they are usually dry and porous. Nearly all species belonging to the pine genus do well on these soils. In this country the Scots fir is the prevailing tree on them, and generally produces better timber than when grown on clay or chalk soils. Wherever the heather abounds we may generally assume that the Scots fir is the most profitable tree to plant, as such ground is usually poor and sterile, and in which few trees will thrive, but which produces a cleaner growth and more durable timber in the Scots fir than soils that are conducive to a rapid and luxuriant growth. The more fertile soils of this class suit the beech, elm, maple, and Durmast oak, but they must be of a fair depth and open nature, so as to allow the roots to penetrate freely in all directions. When moderately damp, or when resting on a clay subsoil, larch thrives well on all soils of this description, but when too dry and arid it is subject to dry rot ; and the same may be said of spruce and silver fir. Pure sand is affected by drought less than any soils, but is usually too deficient in plant food to bring timber to maturity. 110 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. Calcareous.—All these soils contain a large quantity of carbon- ate of lime, and on the chalk formations the soil frequently consists of little else. Owing to this fact, many plants refuse to grow on soils of the latter description at all, and therefore the choice of plants is more limited for this class than for the other two. Amongst the hardwoods, beech takes the precedence in England, ash being better adapted for the north, although chalk formations are not found in the latter part of the United King- dom, and these remarks scarcely apply to it. Many coniferous trees, the pines especially, fail to thrive on chalk, but spruce, Austrian pine, and cedar do very well. The larch also succeeds fairly well up to a certain age, but the dry rot is liable to affect it. On wet limestone soils larch should never be planted, as their close pasty nature render them totally unsuitable to that tree, and blister inevitably results. Peat moors or bogs, properly speaking, are not soils, but as they are sometimes utilised for growing trees, they may be considered as such here. They consist entirely of vegetable matter, being the partially-decayed remains of semi-aquatic plants. Until draining has drawn off the superfluous moisture, and allowed the air to act upon and decompose the inert vegetable matter, plants, or rather trees, will not grow on them, but when this has been effected certain trees thrive fairly well. Birch, alder, willow, aspen, spruce, and Scots fir are the most suitable. When thoroughly decomposed and mixed with inorganic matter, they often form very fertile soils, suitable for the majority of trees that like a light soil. To briefly recapitulate what has been already written on the choice of plants ; the conditions of soil, climate, and altitude should be considered conjointly, and each should be considered as equally influencing the growth and ultimate success of a plantation. Although mixed plantations may be justifiable in some cases, yet a careful examination of the soil and situation, together with a knowledge of the climate, should enable a competent forester to select one, or at the most two, species as the most likely to give the best results, and thereby allow the species selected to receive the proper sylvicultural treatment it requires in order to give the best yield of timber. Certain trees which are more valuable in an early stage than those constituting the ultimate crop may, how- ever, be planted as nurses, to be taken out in thinning, and one here and there might be left for the sake of variety. Larch THE FORMATION OF PLANTATIONS. ite and spruce are the most suitable for this purpose, the former being the most valuable in sheltered situations, the latter in exposed ones, owing to its rigid and erect growth. Laying off the Ground. The usual method adopted in planting a space of land is that of performing the whole of the work in one, two, or three seasons, according to the extent of the ground, state of the weather, and the number of hands employed, and with small plantations this is probably the best plan. But when several hundred acres are to be planted, a proper working plan should be drawn up and adhered to as far as possible. Instead of planting the whole of the ground in the shortest time possible, it should be divided into divisions or blocks of such sizes as to be conveniently planted, thinned, and cut in one season respectively. This system has many advantages, as, for instance, allowing the forester ample time for performing the above-named operations, giving more steady employment to workmen, and preventing a large quantity of mature timber standing in the plantation at a time when the demand for such may be limited, thereby obliging the proprietor either to sell under value or allow the trees to stand after reaching their maximum annual increment, which would result in a reduc- tion of the returns that might otherwise be realised in a given period. Take, for example, a plantation of a thousand acres, containing various examples of soil, and at different altitudes. To plant such an area in four or five years would necessitate the employ- ment of a large staff of men, probably larger than the ordinary staff constantly kept by the forester. Unless a number of extra hands were specially engaged for the work, this would cause much of the ordinary winter work to be thrown back or neglected altogether, which would seriously interfere with the plans and arrangements regarding the other woods on the estate. But if the ground were laid off into squares or blocks of say 10 acres each, so many of these blocks might be planted annually without interfering seriously with other work on the estate. Assuming one hundred years to be the period required for bringing the crop to maturity, one block planted annually would provide for a similar area annually becoming ready for the axe after the first century had expired, and during the course of the second and 112 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. each succeeding century, so longas the ground was replanted after being cleared. But unless the trees were all growing under the same conditions in respect to soil and situation, those on the most favourable parts of the ground would arrive at maturity much earlier than their less favoured neighbours ; and in order, there- fore, to prevent the necessity of cutting before ripe, or causing a break in the returns, the ground should be classified into one, two, or three classes, according to its estimated capability of producing timber, or the length of time each class would require to bring timber to maturity, and a block in each class planted in the same year. Let the ground be supposed to consist of 500 acres of Class I., capable of bringing timber to maturity in 80 years ; 250 acres of Class IT., requiring 120 years ; and 250 acres of Class III., requiring 150 years to mature its timber. By dividing Class I. into blocks of 12°5 acres each, and Classes II. and III. into blocks of 8-3 acres each, and planting a block in each class annually, we should have a continuous crop of mature timber from the 80th to the 180th year from the time planting commenced, the latter operation extending over a period of 33 years, about 30 acres being planted annually until the work was completed. Should the ground be at all exposed, planting should commence on the leeward side of it, and gradually worked up to the windward side, as by this method the removal of those blocks which require cutting first is effected without exposing the ones immediately adjoining them to the prevailing wind, and the tops of the trees present a uniform slope to the wind, and it is therefore less likely to do damage. The above system has the disadvantage of giving a plantation on a hill-side a patchy appearance, owing to the great difference in the sizes of the trees, but this would only be the case when the ground presented a great many variations of soil and exposure, as when planting proceeded steadily in one direction this would prevent such an appearance from being given to it. The formation of roads at the time of planting is quite unnecessary, besides adding greatly to the compound interest on the initial expenses. They should, however, be marked off, and the ground left unplanted, or if planted, such trees should be used as are likely to be of some value when the time comes for their removal. Narrow rides about 13 feet in width should separate all blocks from their neighbours, and should be kept free of grass and rubbish, as in case of fire they may prove of great THE FORMATION OF PLANTATIONS, 113 service in preventing it from spreading from one block to the other. This precaution should always be taken in the vicinity of a railway, as sparks from passing engines frequently ignite the dry grass in adjoining plantations. Formation of Local Nurseries. The custom of getting plants direct from a public nursery, and planting them in all sorts of soils and situations, has a great deal to do with the frequent failures and great loss of plants incurred in planting hilly and poor ground. In addition to the rough treatment they receive in uplifting and transit, and the consequent exposure of the roots, the change from a rich soil to thin, hard, and poor ground usually found on hill-sides and moorland cannot be favourable to the plants starting into a healthy growth until several years have elapsed after transplanting has been effected. The structure of roots differs a great deal according to the soil in which they exist, and it is evident that roots which have been developed in a soil of one description are ill adapted for carrying on their ordinary functions when suddenly removed to a soil of the very opposite character, and new roots must there- fore be formed before the plant can extract a proper amount of nourishment from the soil. Nor does this change merely affect the roots, but the protoplasm throughout the plant has first to accommodate and adapt itself to its new and altered conditions before it regains its former activity; and until these changes have been effected the plant does little more than exist for the first year or two after removal. The ravages committed by rabbits on plants when first put out are probably due in a great measure to their unhealthy and weakened condition from the above causes. It has been frequently remarked that self-sown plants are not nearly so liable to be touched as planted ones are, and there is every reason to suppose that this is chiefly owing to the more healthy and vigorous condition of the former during the early stages, as, when once the latter have recovered from the effects of the move, they are less frequently attacked, or if they are, it is usually the weakest plants that suffer. The true explanation of this fact I have never seen nor heard, but those laws of natural economy which ensure the survival of the fittest have probably something to do with it. The formation of local nurseries on the site of intended VOL. XIII. PART I. H 114 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. plantations would do away with many of the evils enumerated above, and, there is little doubt, would prove the most economical when forming extensive plantations on poor soils, as there is little difficulty in raising Scots fir, larch, and spruce on such ground. They should be formed on well-drained slopes falling gently away to the west or south-west if possible, and the soil should be of the same character as that prevailing over the ground. They should be in as sheltered situations as possible, but not likely to favour frost. They must be securely fenced against game, and the seed-beds should be protected from birds by means of wire-netting stretched over the top. The soil should be trenched as deep as possible, and, if very poor, should be enriched by the addition of leaf-mould, road-scrapings or parings, or anything of that nature. Spruce branches should be stuck round the outside of the beds when the seed is germinating, to shelter it from the wind and sun. The sowing of the seed and subsequent treatment of the plants should be the same as carried out in ordinary home or public nurseries, but being of slower growth, they might stand an additional year in the nursery lines before being planted out, and the seed should be sown rather tater than usual, as larch is extremely liable to be injured by late frosts. The selection of the seed from trees standing in similar localities to that of the future plantation should be care- fully attended to, and only cones off trees possessing good timber qualities and of clean growth should be gathered, as the import- ance of this matter to the ultimate success of the plantation is often ignored, or neglected, with unsatisfactory results. It may be argued that a strong vigorous plant from a public nursery is more likely to survive the ordeal of transplanting than a weaker and less vigorous one, owing to the greater amount of reserve matter stored up in the stem of the former than in the latter, and this is, no doubt, perfectly true when both plants have been growing under the same conditions, and are subjected to the same treatment before being finally planted out; but when the stronger plant has several great disadvantages to contend with which are not shared by the weaker, the positions of the two plants may be considered as reversed. It must also be remembered that the embryo growths in the buds of the stronger plant require a proportionally larger amount of nourishment to develop them, and therefore the apparent advantage in regard to reserve material is less than might appear. It must be admitted, then, THE FORMATION OF PLANTATIONS. was that plants raised on the ground have the advantage so far as transplanting is concerned, and the additional trouble and expense of forming a nursery is fully compensated for before the planting of a large area is completed. Size of Plants. The size of the plants at the time of planting must depend a good deal upon the nature and situation of the ground. For exposed and elevated situations, one-year seedling, one year trans planted, are probably the best, as they have a better chance of getting established in the ground. In more sheltered positions, and where the herbage is coarse and rank, two-year seedling, two years transplanted, may be used, and in ordinary situations no advantage is gained by planting them larger than the latter size. The former size refers only to conifers, the latter to both conifers and hardwoods. The great desideratum is to obtain plants with their roots and tops equally proportioned, or if one of the two preponderate, let it be the former. Distance between the Plants. The distance apart at which the trees are to stand after the final thinning should determine the distance apart at which to plant. To fully utilise the ground, and give the plantation a regular and uniform appearance, the special requirements of each species used (or more properly of the species to form the ultimate crop) in regard to space should be carefully considered. The probable rate of growth and capabilities of the ground will have to be considered, but the principal thing requisite is a knowledge of the maximum number of trees which a given acre of ground is capable of growing and bringing to maturity. By dividing the area by this number, the space occupied by each tree is obtained ; and the square root of this area, divided by a power of two, corresponding to the number of regular thinnings intended, gives the distance which should separate the young plants. This may be considered unnecessary and too theoretical, in view of the many accidents and casualties which may occur during the life- time of a plantation, while no allowance is made for the greater demands of strong and vigorous trees for space compared with their weaker neighbours. The first objection has no more weight than the case of a man who objected to being educated when 116 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY, young, for fear of dying before he could make use of it; and the second would only apply to mixed plantations, which are not alluded to here. The average distances apart at which the following trees are usually planted, are—Scots fir, 2} to 3 feet; larch 3 to 4 feet; spruce 2 to 4 feet. Hardwoods are usually planted at good distances apart, about four times the number required for the ultimate crop say, and the intervals filled up with coniferous nurses, to 3 or 4 feet apart. The following distances oak, 8 feet; ash, 9 feet; elm, 12 feet; beech and hornbeam, 6 feet apart, respectively, the distance for oak being one-eighth of that of the ultimate crop. Mixed plantations are usually planted about 3 feet to 4 feet apart. are suitable for Planting. Planting may be performed at any time during the natural suspension of growth, which, in this country, means from November to April inclusive. The spring months are preferred by many foresters for planting, especially where the ground is at all wet, as the roots commence to grow before they have time to lose the vitality of the fibrils, which frequently takes place in wet soils when the roots have been bruised or broken in lifting. On dry, sandy soils, autumn planting usually gives the best results, as they are firmly established in the soil before the drought of summer commences, and the notches are not so likely to open and loosen the plant as when planting is done in the spring. Planting should only proceed in fresh, open weather, and never during frost or snow. For small plants notching is the cheapest and most expedi- tious method of planting, and for this the planter should be provided with a sharp half-worn garden spade. Inserting his spade perpendicularly into the soil, he makes two cuts or notches at right angles to each other, shaped like the letter L. He then lifts up the corner of the notch so as to allow the roots of the plant to be inserted beneath the spade, which is then withdrawn, and the soil falls back into its place, covering the roots, and is made firm with the heel. The planters should work in extended lines, each man taking his distance from his right or left hand neighbour, according to the side the leading man is on. Every two men should be accompanied by a boy or woman to carry the THE FORMATION OF PLANTATIONS. 1dey plants and insert them in the notch, the planter seeing that the roots are not twisted or doubled up before he withdraws his spade. The boys and women should be provided with aprons with large pockets for carrying the plants, the latter being supplied to them by others specially told off to carry the plants from the “sheugh” to the planters, so as to prevent the roots from long exposure to the sun and wind. In pit-planting much the same method is adopted as the fore- going, except that instead of making a notch, a small hole is taken out about a foot square; the boy holds the plant in the centre, while the planter fills in the finer soil immediately round the roots, leaving the worst for the top. In damp soils pitted plants are apt to be thrown out by the frost if planted in autumn, and are therefore best left until the spring. When planting hardwoods with coniferous nurses, they are often planted at their proper distances before or after the nurses, which simpli- fies matters for the planters and prevents mistakes. In all planting operations careful work should be encouraged before speed, and in very rough and stony ground it is better to take out a hole and remove the stones, than to squeeze and crush the roots into places where there is nothing to support them. Sowing in situ. The practice of sowing in situ, or sowing the seed on the spot in which it is intended to grow, is rarely resorted to in this country, and it has many disadvantages, compared with planting, on rough or waste ground. It might, however, be adopted in afforesting old arable land with hardwoods, such as oak or chestnut. The hard- wood seed should be sown in lines about 8 feet apart, or double that distance, if the ground is suitable for growing larch to a fair size, and the latter tree substituted between the hardwoods, as it is more valuable when young. ‘Two or three seeds should be sown or dibbled into each spot intended for the site of a tree, which should stand about 8 feet apart in the lines, thus allowing for contingencies in the shape of bad germination, damages by vermin, deformed plants, &c. If the ground be fairly clean, the intervening spaces might be sown thinly with larch seed, but if dirty, it would stand in great danger of being smothered before it attained any size, and planting would be preferable, the plants being put in about 3 feet apart. Spruce and Scots fir might also be used if the ground were unsuitable for larch, but the latter tree being double the value of 118 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. the former two, should always be used if possible. Other hard- woods than the two mentioned might be raised in this way, but owing to their strength and vigour as seedlings, oak and Spanish chestnut are better adapted for it than any others. When the ground is in good condition, and the heather short, good results might be obtained by sowing Scots fir broadcast on heathy moors and hill-sides, as the regularity with which this tree comes up on such ground where self-sown, produces almost as good and perfect a crop as could be secured by planting. It is only on heath-covered ground, however, that this would be likely to succeed, as grass or any other herbage is too thick and close to allow the seed to obtain a good hold of the soil. Of course, a large per- centage of the seed would be lost, and therefore this system could only be recommended when seed is cheap and easily obtained, but many barren acres of hill-side and moorland might be afforested by this method at a considerably less cost than planting. Protection from Ground Game. Where ground game abounds, it is necessary to protect the young plants by means of wire-netting. This should be supported by short posts, about 4 feet long, driven firmly into the ground every 6 or 8 feet, or the netting may be attached to a wire fence when if surrounds the ground requiring protection. A small trench about 3 inches deep and wide should be taken out, and the bottom of the netting placed in it, about 3 inches at the bottom being laid flat, and the scil replaced. This prevents rabbits from scratching holes underneath it, which they quickly do when it merely touches the sur- face of the ground. All holes should be ferreted and stopped after the netting is up, otherwise some may be left inside. To protect any large area from rabbits by means of netting is practically impossible, the only effective remedy being that of keeping them down by shooting and trapping, and allowing their natural enemies, such as stoats, weasels, foxes, &c., to restore the balance of nature. The settling of this question, however, is usually outside the forester’s jurisdiction, and he must do what he can, and leave the rest to take its chance. Management for First Twelve Years. The principal work to be done during the first two or three years after planting will be beating up blanks and keeping down rubbish. {HE FORMATION OF PLANTATIONS. 119 If a fair proportion of the trees survive, the former operation is often neglected on the grounds of economy, and rendering a profitless thinning unnecessary. When the production of large trees is alone aimed at, such an omission may be commendable, but when a crop of clean-grown timber of good quality isdesired, it has several objections. In the first place, it favours the growth of coarse side branches wherever gaps exist, which often attain considerable size before they are overpowered and killed by the closing up of the leaf canopy, causing black knots in the timber. Secondly, the stems are exposed to the sun, and unequal zones of soft and sappy wood are formed early in the season. Thirdly, the complete subjection of the herbage is considerably retarded, and the roots of the trees are deprived of a good deal of the available food. Fourthly, the mechanical condition of the soil produced by close shade, and a covering of decaying leaves, which is so eminently favourable to the production of roots, is not attained until the trees are in close order, and is therefore longer in taking place when gaps are numerous. The above objections more than counterbalance any advantage to be gained by the omission of beating up, and therefore it should be attended to wherever practicable. The subjection of rubbish depends a good deal upon its nature. Whins and broom must be carefully watched and kept from closing over and smothering the plants, and if they are cut over with a hand or hedge bill every two years until the plants are well above them, there is little danger of this taking place. Grass rarely does much harm, except to very young plants, which should never be planted amongst it. Brackens, brambles, &c., will require annual attention for a year or two, but the work should never be entrusted to careless or irresponsible hands, or more harm is likely to be done than good. After the plants are fairly established in the soil, they will require little attention until the eighth or tenth year, according to the rate of growth, but hardwoods should be gone over, and all double leaders removed. Oaks often refuse to start freely into srowth after being transplanted, and when this is the case they should be cut over close to the ground, and allowed to break away from the bottom, all but the strongest shoot being removed after a year or two. About the tenth year after planting, the first regular thinning is usually performed. This is generally done by cutting out every other plant, and leaving them about double the former distance 120 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. apart, the nurses only being removed in the case of hardwoods. No doubt this method provides for the welfare of individual trees better than any other; but sylviculture recognises the claims of a mass or number of trees collectively, rather than the special requirements of the units which compose the mass, and aims at growing timber and not merely ¢rees, and therefore we might consider whether the usual method of thinning is the best to attain the object in view. In all natural forests it is evident that the operation of thinning by means of the axe and saw has never been carried out, and yet it is from such forests that our best timber supplies have been drawn, and an endeavour will be made to show the reason of this fact. Let us take the case of a piece of heath-covered ground that is being self-sown by Scots fir. Here we find the plants that show themselves first scattered here and there over the ground, some of them separated from each other by 20 or 30 feet. Every successive year a few additional plants appear, gradually filling up the blank spaces, until the whole surface of the ground is eventually covered with plants. By this time, however, the first plants that appeared will be con- siderably in advance of their youngest neighbours, and will have acquired a certain amount of superiority over the others, according to their age and vigour. It is evident that if nothing occurs to stop the growth of these larger plants, they will be in no danger of being overtopped or smothered by thei neighbours, but will continue growing until they have reached their full height. But although they may have free space for upward growth, they may be checked or stopped altogether from developing their lateral branches by smaller but equally vigorous plants that are growing up around them. Suppose a large plant to be 6 or 8 feet in height at the time a smaller plant, standing 6 feet away, is only 3. Assuming the lowest branch on the former tree to extend 3 feet in the direction of the latter, it would allow a space of nearly 3 feet between the nearest branches of the two trees, assuming the branch in question to be the longest on the side of the tree. This space would gradually decrease until the branches of the two trees touched, when their growths would be checked and ultimately stopped, causing their death. Other branches, higher up on the stems of the two plants, would, however, be meeting in the same way and sharing the same fate, always leaving, however, a clear space between the leading shoot of the smaller plant and the nearest branch opposite on the larger. Supposing the two plants to keep THE FORMATION OF PLANTATIONS, Al their relative positions, and make uniformly equal growths until both had reached their full height, a system of natural pruning would have been carried out on the sides of both stems that faced each other, the branches on the smaller plant being checked and killed earlier in life than those on the larger one however. If small plants had stood on every side of the large one, the pruning process would have been complete, and we should have a typical illustration of what takes place, more or less, in a natural forest, and which produces pine timber of such excellent quality and almost free from large knots. It is not contended, however, that such a method is the best and most economical for the practical forester to adopt in the case of plantations, and there are several reasons for coming to this con- clusion. In the first place, the trees in a plantation are nearly equal in size, and would, therefore, be in danger of sacrificing one another before one could rise above the other. In the case of the natural forest, too, only one out of every ten may be placed in the way we illustrated, and therefore the proportion of well-grown timber trees will be comparatively small, and not sufficient to give a fair yield. But in spite of these objections, it is evident that the saine principles will hold good in the case of artificial plantations, as in the natural forests, although the treatment must be modified to suit the altered conditions. Even in artificial plantations, however, by the time the trees require thinning, they will not be found all one size. Some will be found 2 or 3 feet taller than others ; or, in other words, natural selection will be operating on the crop. The duty of the forester, then, will be to assist this operation as much as possible, and endeavour to secure a regular distribution of strong, clean-growing trees, by checking the tops of all trees that are competing too closely with those that are intended to grow until the second thinning. By the ordinary method, the unnecessary (?) trees would be taken out altogether, but the objections to this method are these :—In the first place, it exposes the soil to the sun and wind, and it becomes hard and dry and unfavourable to any roots that may have found their way along the surface ; Second, grass and rubbish again begin to grow, and appropriate the moisture and humus ; Third, the stems of the plants are exposed to the sun, and the development of side branches encouraged, causing the formation of inferior wood. Other objections might be raised, but these are the principal ones, and are thought to be sufficient to justify the 122 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. adoption of the above method, recommended generally, although cases may occur where it might not be practicable. Conclusion. To go fully into every subject bearing on the formation of plantations, would require more space and time than could be expended on an ordinary essay, and therefore many subjects and operations are only briefly described and treated upon; but as their general application has been kept more closely in view, than their particular adoption or execution in any one locality, no advantage would have been gained by going too closely into details. Some of the theories propounded in this essay are based upon observation rather than experience, and therefore difficulties may be in the way which might render their practical adoption impossible ; but as custom without reason has been defined as an ancient error, the risk of committing a modern error has been incurred, rather than the recommendation of any customary operation for which no logical reason could be given. TREES AND SHRUBS FOR PLANTING IN TOWNS. 123 VIL. Zrees and Shrubs for Planting in Towns. By A. D. Wesster, Holwood, Kent. To those whose lot is cast in or near our more important centres of industry, this subject is of vast importance, and one which, at the present time, occupies a large share of public attention. The surprise experienced by most persons in this country on first visiting any of the larger Continental cities—Paris, Brussels, or Berlin, and where street planting would seem to be considered as a matter of paramount importance—is great indeed, and invariably leads to the somewhat pertinent question, ‘‘ Why cannot we make our cities beautiful by planting suitable trees and shrubs?” No doubt there are a few drawbacks to be encountered in so doing, but that very much more might be accomplished than has hitherto been done is clearly evident to those who have devoted even a small share of attention to the matter. The atmosphere of our larger towns and cities—London, Glas- gow, Liverpool, Manchester, and Sheffield—is, it must be candidly admitted, impregnated to a far greater extent with noxious fumes and vapours than is that of any of the Continental towns above mentioned, and, therefore, the difficulty of establishing many trees and shrubs is correspondingly increased. Observations and experiments carried on during the last ten years in three of the largest towns in Britain—London, Glasgow, and Liverpool (a trial garden was for this express purpose instituted in one of the most smoky districts of East London) proved, however, that there are not a few trees and shrubs well have clearly suited for withstanding even the deleterious effects of the impurest of town atmospheres. Not for one moment do I wish it to be inferred that there are not certain districts—to wit, the environs of the Lambeth potteries, and some of our huge chemical works—where, do what we will, vegetation, be it of whatever kind, will not succeed; but as we recede from these centres of sickness and death, particular trees and shrubs flourish amazingly, and no better example can be pointed out than the healthy and rapid-growing specimens that adorn the Thames Embankment, and which are removed but a very short distance indeed from one of the barrenest and most miserable of the city suburbs—the pottery district. That certain trees and shrubs succeed best in particular towns 124 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. is another strange fact, for, curious as it may seem, the smoke-proof London plane is by no means the best tree for either Liverpool or Warrington, particularly the former town, where the sycamore has been found to be far better adapted. In the very centre of Sheffield the Canadian poplar has been found to be by far the most useful tree, while in some of the worst localities in the colliery districts the chestnut and variegated-leaved sycamore are the greatest favourites. Even the rhododendron does well in the most smoky parts of the town of Bury, Lancashire. No better example could be adduced of how certain trees favour certain towns, than two or three kinds of poplars which grow with unabated vigour at Gatley, a small town near Manchester ; while at Bury, about equally dis- tant on the other side of that city, they positively refuse to grow, and that too after many unsuccessful attempts to get them established. Neither the rhododendron nor the laurel are at all suitable for the smoky districts of London; but casual observers may form a different opinion, from the appearance of such of these shrubs as are replanted annually, the semi-sickly subjects being replaced at stated times by those that are fresh and vigorous. In the smoky and impure (chemically) atmosphere of Glasgow the thorn and beam tree (Pyrus), as also several kinds of Retinospora, thrive amazingly, much better than they do in any of the large English towns, Why certain trees and shrubs succeed best in particular dis- tricts or towns is, perhaps, readily enough explained by the conditions of soil and situation, as well as the particular industry of the inhabitants. Coal smoke from the multitudinous chimneys of our larger centres of industry is no doubt bad enough; but when we have to contend with an atmosphere largely impregnated with the outcome from chemical, gas, or iron works, the difficulties to be encountered are great indeed. Preparation of the Ground and Planting.—In order that success may crown the effort, it may truly be said that no work of the horticulturist requires more skill and good management than the proper planting of trees alongside streets and avenues. The materials with which roads are usually made up are ill-fitted for sustaining a healthy condition in trees, at least for any great length of time, and this is well known to those who have taken any interest in the matter—broken stones, clinkers, and gravel affording but small support to vegetation, be it of whatever kind, but particularly large-growing trees and shrubs. Many failures in TREES AND SHRUBS FOR PLANTING IN TOWNS. 125 street tree planting from this very cause might be pointed out, and in not a few cases the future result will certainly be discreditable to all concerned, simply because the work has not been properly done. In crowded streets and squares, where the air is vitiated with impurities, and the soil hard and often surcharged with gaseous matter, tree planting is quite a different matter to what it is along the side of a field. In the latter case it may be sufficient to open a smal] pit, insert the tree, and stake it ; but in our large towns the case is totally different, for the soil, hard as iron, and composed mainly of clinkers and shingle, affords but little nourishment to a rapid-growing tree, and one that, moreover, has to do battle above ground with the deleterious effects of an impure atmosphere. Another fruitful cause of failure in street planting is placing the pavement above the roots, and in too close proximity to the stems. The roots should always be allowed plenty of breathing room, and to effect this a good-sized space should be railed off around each tree, and no pavement laid within it. In so doing a double benefit is conferred, by allowing free access of rain to the roots, and avoiding the accumulation of noxious gases in the ground (as has been proved to be the case when close pavement has been used), which are inimical to the welfare of the trees. In proof of what is said, we may refer to the trees at the Chelsea end of the Thames Embankment, which have been planted as above directed ; and that success has amply crowned the effort cannot be denied, for certainly that noble avenue has no equal in any British town. Where street trees are to be planted, a good-sized patch of ground —say, at least 6 feet in diameter and 4 feet in depth—should be thoroughly broken up, and if the soil is of inferior quality, which will assuredly be so in 90 per cent. of the pits, good fresh loam should be substituted. By undermining the sides of the pits a much larger receptacle for the fresh soil will be formed, and this will not occasion so much of the footway and pavement being torn up as if the pits were of equal diameter top and bottom, The plants used should be such as have been specially prepared for the purpose, by being frequently transplanted for some years previous to being placed in their final position. They should be stout, stocky, well-rooted, clean, and from 6 to 8 feet in height. In planting, spread the roots well out around the stem, and do not bury too deeply, the mark visible on the stem as to how deep 126 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCTETY. the trees stood in the nursery border being the best criterion to go by. As regards the best time to plant town trees opinions differ, but there can be little doubt that spring is preferable, for the good reason that, as they start into growth at once, they are not so likely to suffer from smoke and other deleterious affections as if they remained during the winter in an inactive condition. Staking the trees so as to prevent rocking by the wind, and consequent damage to the roots, should be set about immediately planting is finished. Circumstances will be the best guide as to how this should be done, but it is generally found necessary, even when the trees are surrounded with iron railings, to drive a stout stake firmly into the ground on the windward side, and as close to the stem of the tree as possible. To this the tree should be made fast with teased-out tarred rope, and to avoid friction the rope may be crossed between the stem and stake. These simple matters connected with the preparation of the eround, planting, and staking are so important in town planting that they should never be lost sight of, for while they add but little to the cost, the advantage gained is very great. | Advantages of Town Trees.—Not only for the cheerful aspect produced by trees when planted alongside streets and thoroughfares, but also from a sanitary point of view, they are of special value and the greatest importance. That a quantity of healthy-growing foliage has a wonderful effect in purifying the atmosphere is a recognised fact, and certainly far more than compensates for any damage to health that might be occasioned by its decay in autumn. Bearing on the question of trees in towns, Dr Phené, at the Social Science Congress at Edinburgh, remarked as follows :— “To the occupants of houses in streets having a northern aspect, the glare of reflected light is injurious; but the effect would be much modified by the coolness to the eye produced by the green of trees. In ancient surgery, persons having weak or declining sight were advised to look at the emerald. In the old style of building, the streets being narrow, were both cooler, from the sun not being able to penetrate them with direct rays, and less subject to noxious exhalations from the scouring and purifying effects of the searching air to which narrow streets were subject, so that while there was no space for trees, there was also less necessity, Wide streets, on the contrary, are hotter, and require the shade of trees to cool them, and, as in the case of London, which has so TREES AND SHRUBS FOR PLANTING IN TOWNS. 127 far done without trees in its streets, not only are modern streets compulsory wide, but the enormous increase in metropolitan build- ings renders every sanitary question one of importance ; and the chemical properties of trees, as shown by experiment, gives them an important standing on that ground, irrespective of ornament or the pleasure they produce. But that which is important in such localities is more imperatively demanded in poorer districts on the score of health, as during the last year alone 21,000 new houses were erected in London, producing 400 streets, with 71 miles and 468 yards of promenade.” TREES. The Oriental or Common London Plane (Platanus orientalis acertfolia).—This variety of the Oriental plane stands first in the category of select town trees. Not only does it grow vigorously in towns, but it is peculiarly well adapted for withstanding the smoke and other impurities of their atmosphere. Repeated experiments have clearly proved that in London this tree flourishes better than any other, and a visit to the Thames Embankment, and several other of the urban districts, will substantiate the statement ; while the fine old tree which still exists at Cheapside, and the equally beautiful specimen, which has hardly room for perfect development, in the Court of Stationers’ Hall, Ludgate Hill, afford other examples of how well suited this handsome tree is for doing battle with the smoke and impurities of the great metropolis. As a diversity of opinion has existed about which variety of plane it is that grows with such vigour in and around London, it may be stated that, on a careful examination of a large number of specimens, the variety P. 0. acerifolia was found not only more commonly distributed, but likewise better suited for town planting than the typical P. orientalis. This valuable variety is readily distinguished from the normal plant by the less deeply divided leaves; and from the American plane (P. occidentalis), with which it is not infrequently confounded, by the many fruit “ balls” which are attached to each peduncle, the fertile catkins of P. occidentalis being for the greater part produced singly. But not only for its value as a town tree is the Oriental plane much sought after ; for the giant proportions to which it attains, coupled with the handsome, finely cut leaves and easy habit of growth, renders it one of our most desirable ornamental trees. Then it is of the easiest culture, succeeding extremely well in soils 128 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. of the very opposite qualities. Taking everything into consideration, we question much whether any other of our forest trees is of greater or even equal value with the plane for town planting. The Maidenhair Tree (Ginkgo biloba).—A prolonged visit to the very worst smoke-infested slums of London, has now quite convinced me that the maidenhair or ginkgo tree is one of the most valuable that can be planted in the impure atmosphere of a town garden. Few trees, | am fully aware, can compare with the one in question for withstanding the deleterious effects produced on vegetation generally by coming in too close contact with the impurities of our great centres of industry. The ample delicate green foliage betrays—even late in the season, and when about to be cast off—little evidence of the fierce struggle that must almost constantly go on between vegetation and the smoke and filth of our towns and cities. That the thick leathery leaves and strong con- stitution of the tree play an important part in keeping it free from disease is clearly evident, while the fact of the leaves being renewed annually must go a long way towards casting off the sooty nodules which work such havoc on the tender foliage of most trees. At no less than five places in and around the great metropolis— and such places, too, where one is almost stifled with the fumes from chimneys—the maidenhair tree may be seen almost in as fresh and flourishing a condition as those enviable specimens on the Isle of Man ; indeed, about as large trunks as can be seen anywhere are growing in the smoke of Chelsea. Not only asa standard tree is the maidenhair valuable, but it is also one of the prettiest wall plants with which I am acquainted, and how many bare ugly erections of brick and stone in our city streets want a bit of greenery I would not like to say. The Ailanthus, or Tree of Heaven (Adlanthus glandulosa), may be seen in a flourishing condition in many of the London streets and byeways. By its rich green spreading foliage, the Ailanthus is, during the summer months, a great favourite with lovers of sylvan scenery, the leaves in many cases reaching to a length of fully 2 feet. It is a tree of very rapid growth when suitably placed as regards svil and situation, shoots nearly 2 feet being often produced in a season. Tt has been largely planted in many Continental cities, and has proved itself one of the few trees that are capable of withstanding the impurities of a town atmosphere. The greenish-white, incon- spicuous flowers, are freely produced, and are succeeded by TREES AND SHRUBS FOR PLANTING IN TOWNS. 129 innumerable fruits resembling the keys cf the ash, but of a reddish- brown colour, which imparts to the tree a wealth of autumn glory that we unfortunately are seldom permitted to witness in this country. The Black Italian Poplar (Populus monilifera).—Next to the plane amongst forest trees, I consider the black Italian poplar to be the most valuable for planting in smoky towns. Asa proof of this, there are to be seen numerous fine specimens of this tree in a flourishing condition, and clothed with the most healthy foliage, in some of our largest cities—to wit, London, Glasgow, and Liverpool. The black Italian poplar may be somewhat stiff in outline, but there is, nevertheless, an air of grace about it that is wanting in any other tree I can bring tomind. It is a tree of the readiest culture, while, as to its rate of growth, a specimen of 100 feet in height has attained to that size in less than sixty years. The wood, unless for a few special purposes, such as cart-bottoms, brakes, &c., is not of great value; but the tree is, nevertheless, a profitable timber- producer when grown in suitable soils. The Canadian Poplar (P. canadensis) and its variety, P. c. nova, are excellent trees for planting in smoky localities. The former succeeds admirably in the very centre of Sheffield, in the old parish churchyard, where for hundreds of yards away not a particle of living vegetation is to be seen. The variety nova is a very superior tree for street planting, it being far more ornamental and of more rapid growth than the black Italian poplar, and equally reliable for retaining a healthy and flourishing cendition under the adverse circumstances connected with a town atmosphere. How well it succeeds may be seen in the beautiful avenue that was formed of it and the Oriental plane some years ago at Wimbledon Park. The Abele Poplar (Populus alba) grows with great freedom where subjected to smoke and foul air. In the very heart of our largest towns, it may be seen flourishing in a manner that is almost incredible. It is a pretty tree, the distinctly cut, ample leaves, with their cottony under surface, being at all times, but especially when agitated by the wind, most interesting, and causing the tree to rank amongst the most ornamental of its kind. It is readily propagated, transplants freely, grows rapidly, and is neither subject to disease nor particular as to the soil in which it is planted. The Lombardy Poplar (P. fastigiata) is another tree that has been planted with some success in and around many of our largest cities, but it cannot equal any of the foregoing for withstanding the VOL. XIII. PART I. I 130 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. baneful effects of a tainted atmosphere. In the outskirts of towns, where the air is purer than amid chimneys pouring forth their volumes of smoke, the Lombardy poplar succeeds fairly well, and imparts an air of grandeur that could hardly otherwise be obtained. The Cucumber Tree (Magnolia acuwminata).—Few planters are aware of how valuable the cucumber tree is for withstanding the grime and soot of large towns. Experiments have, however, resulted in this highly-ornamental and fast-growing tree being added to the list. Its ample foliage, yellowish-white fragrant flowers, and general contour, eminently fit it for a first place as a town tree. Soil of ordinary quality suits its general wants, although it prefers a strong, yellowish moist loam. The Tulip Tree (Liriodendron tulipifera).—Excellent examples are not wanting of how valuable a tree Liriodendron tulipifera is for towns and streets. It seems to have a wonderful recuperative nature, for scorched, blackened, and encrusted as may appear the falling-off foliage, yet in the following spring it again puts forth a garb of the freshest and richest greenery. The remarkable four-lobed, truncate leaves render this tree almost without an equal for orna- mental planting, while its undoubted smoke-resisting qualities place it high in the rank of town trees. It is not particular as to soil. The Indian Bean (Catalpa bignonioides).—For various reasons this fast-growing tree is to be recommended for planting in smoky localities. It grows with vigour in many smoky centres of industry, is a tree of handsome proportions, and when fully established, flowers freely. The violet-white of the petals of the flowers is well set off by the purple and yellow of the throat. A valuable trait in the character of the Indian bean is that, should accident befall it, and the stem get injured, numerous strong suckers are produced, which, as they grow with great rapidity, soon take the place of the original. Few soils come amiss to it. The common Mulberry (Morus nigra) and the white-fruited form (J. alba) may be seen growing satisfactorily in several of the old gardens and nurseries of the metropolis, and where they are now buried alive, as might be said, in stones and mortar. That they are excellent town trees will be admitted by everyone who sees the fine specimens in Liverpool and Manchester. The Honey Locust (Gleditschia triacanthos) is a tall, spreading tree, one of great beauty, and a very suitable subject for planting in smoky localities. In many of the worst smoke-infested parts of TREES AND SHRUBS FOR PLANTING IN TOWNS. ou London and Manchester are seen goodly specimens of this hand- some tree—not poor, miserable trees, but from their great size, wealth of foliage, and general appearance, betoken perfect health amid their rather adverse surroundings. It grows very freely even when rather carelessly planted, and in soil of inferior quality. In autumn the long fruit-pods give to the honey locust a distinct and curious appearance. The False Acacia (Robinia Pseud-acacia).—Almost by the hundred can the false acacia be seen in London and many other English towns, thus proving that it is one of the most valuable trees that we possess for withstanding the injurious effects of an impure atmosphere. It is, likewise, one of the most ornamental of trees, the great wealth of pure white flowers, and beautiful pea-green foliage, being of the richest description. What renders this acacia of greatest value as a town tree is that it retains its rich verdure till well on in autumn. It grows freely in almost any soil, reproducing itself freely in suitable positions, and soon forms a handsome tree of almost giant proportions. The most suitable for town planting are the upright-growing and free- flowering kinds. The varieties known as Decaisneana, microphylla, macrophylla, sophorefolia, and the upright-habited are most to be desired. The White Beam Tree (Pyrus aria).—In many of the confined spaces in Glasgow, the white beam tree grows luxuriantly, and produces annually great quantities of its brightly-coloured berries. The creamy white of the under side of the leaves is particularly attractive when agitated by the wind, and the wealth of small white flowers is a treat to behold. Few trees are more readily suited with soil, for it may be found in a state of nature growing on dry lime- stone rocks, where there is scarcely a particle of soil. The Lime (Z%lia Huropwa).—Where the situation is not too confined, and where soot and smoke do not abound, the lime may and does succeed ; but when used in the worst parts of the metropolis, it soon shows signs of distress, the tips of the branches dying off, and the whole tree sooner or later showing the fierce struggle it has to endure with smoke and fumes. As an avenue tree, in the more airy and pure parts of a town, the lime has certainly few equals, its general contour and the pleasing shade it affords being points of special recommendation. The Sycamore (Acer Psewdo-platanus).—This tree may be classed as amongst the most useful for planting in smoky towns. In 132 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. Warrington, where the noxious emanations from alkali and other chemical works are most disastrous in their effect on trees and shrubs, the sycamore is one of the few that grow satisfactorily. Being a rapid and strong grower, it is thus seen to be, for a certain time at least, unaffected by its inimical surroundings. The variegated variety would seem from recent experiments to be preferable and better adapted for smoky localities than the normal form. The Weeping Ash (fraxinus eacelsior pendula) would seem to be superior to the common ash for planting in towns. It thrives satisfactorily in many of our largest centres of industry—to wit, London, Liverpool, Glasgow, and Manchester. Being of slow growth and dwarf in size, it is well suited for planting where space is confined. It is of the easiest culture. The Horse Chestnut (@sculus Hippocastanum) and the English Elm (Ulmus campestre) may be seen in a fairly satisfactory way in many town parks, but only where they are not exposed to smoke and soot to any great extent. In confined spaces both these trees soon show signs of distress, the points of the branches gradually becoming unhealthy, and the trees ultimately dying off prema- turely. Taking everything into consideration, neither of these trees can be recommended for planting in smoky districts. The Birch, Walnut, Hornbeam, and one or two kinds of Willow will succeed in the less smoky parts of a town; but they are not to be recommended for planting where the air is constantly impreg- nated with soot and dust. The Mountain Ash, or Rowan Tree (Pyrus aucuparia), has proved itself to be a valuable small-growing tree for planting in urban districts. It is also a tree of great beauty, whether in flower or fruit, one that grows almost anywhere, and with a minimum of attention. In many town streets where the air is vitiated with fumes, the mountain ash grows with great freedom. The Alder (Alnus cordifolia).—In this we have a good addition to the few trees that are really suitable for town planting, for it grows with great vigour, and retains much of its fresh, spring-tide greenness in very smoky and impure localities. Of hardy con- stitution, and unusually strong growth, it seems to defy the sooty emanations from hundreds of chimneys in two at least of our largest centres of industry. The Bird Cherry (Cerasus Padus) may be classed among the | most valuable of our town trees. It is a robust-growing and bright- TREES AND SHRUBS FOR PLANTING IN TOWNS. 133 flowering small tree. Few soils come amiss to it, and even where it is hemmed in by taller-growing trees, and constantly subjected to their drip, it grows and blooms with the greatest of freedom. In many of the back streets and slums of London may be seen well- grown specimens, which clearly demonstrate how well suited it is for withstanding smoke and dust. The Sugar Maple (Acer saccharinum) is a handsome, hardy, and fast-growing tree of moderate dimensions, and one that can justly claim a place in any list of town trees. It will not succeed where constantly subjected to smoke and fumes, but planted in the suburban districts it soon forms a really handsome and distinct tree. Sophora japonica is worthy of recommendation as a tree that is admirably suited for planting in towns. It is of large and rapid growth, with elegant dark green pinnate leaves. Being a native of China and Japan, it may not be perfectly hardy in the colder portions of the British Isles, but it succeeds well in southern England and Ireland, and it thrives admirably in the most smoke- infested parts of London. Thorns of various kinds succeed in town parks and gardens, but they are not to be recommended for the most smoky and confined localities. In Glasgow, however, I have noticed how well suited for planting in the squares and public gardens many forms of the thorn are; indeed, even in London, and where smoke and dust are by no means wanting, they gladden the eye with their wealth of flowers and bright green leaves. The single and double scarlet would seem to be best adapted for withstanding soot and smoke ; and these may not unfrequently be seen of large size and in perfect health. The Tansy-leaved Thorn (Crategus tanacetifolia) is another excellent member of the family for town planting. A noble example may be seen near the entrance to the Glasgow Botanic Garden. The English Yew (Zaxus baccata) can hardly be recommended as a suitable tree for smoky localities, although in suburban districts it grows freely, and there forms a dense, healthy dark green mass. From this it must not, however, be inferred that the yew cannot sur- vive in smoky towns, for it grows freely wherever it is not’subjected to an inordinate amount of atmospheric impurities. Soil of fairly good quality should be used when planting the yew, particularly where the surroundings are unfavourable. 154 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. Hollies of various kinds are very suitable for planting in cities, but they are not to be recommended for using in densely populated districts. For a time they may and do succeed, but they ultimately begin to show signs of distress by the tips of the branches dying off bit by bit. The dwarf variety of the common holly is one of the best for smoky districts, where it grows freely, and looks bright and healthy, often in most objectionable quarters. It succeeds much better than any of the others in the London squares and parks, while it is valuable in the more confined parts of Liverpool and Manchester. In Glasgow and Edinburgh it also grows freely. Two other species at least do well where they are not subjected to an inordinate amount of smoke. ‘These are 7. Balearica and I. Hodginsti, two very distinct and desirable hollies. SHRUBS. Of these there is rather a long list of kinds that are suitable for planting in smoky localities. Evidently deciduous species possess an advantage over evergreen kinds in the total annual renewal of their leaves ; and hence it follows that, as with trees, deciduous shrubs should have the preference. The following list includes only such kinds as have been proved suitable for town planting :— Osmanthus ilicifolius is one of the handsomest of evergreen shrubs, and also one of the few that succeed in a satisfactory way when subjected to the impurities of a town atmosphere. In the smokiest districts of both London and Liverpool, it is unquestion- ably the best all-round shrub. The holly-like leaves are thick and of firm substance, and the inconspicuous yellowish-green flowers are also much like those of the holly. Ligustrum coriaceum is a fitting companion to the last, so far at least as its powers of withstanding the effects of an impure atmosphere are concerned. Being an evergreen, it is peculiarly weil suited for planting in the town garden, where it grows with great freedom. It is easily managed, not particular as regards soil, is readily increased, and bears trimming in with perfect impunity. Aucuba japonica.—This well-known evergreen shrub is of great value for planting in urban districts, it being able to do battle with a more than ordinary amount of atmospheric impurities. For TREES AND SHRUBS FOR PLANTING IN TOWNS. 135 this reason it has been largely planted in town squares and gardens in the most crowded and densely populated parts. As an orna- mental shrub, too, the Awcuba is well worthy of extensive culture, its fine, large, glossy, and beautifully mottled leaves being at all times objects of admiration. It is easily raised from cuttings, and grows with great freedom in any soil. Griselinia littoralis.—Although a little-known evergreen, this is well suited for town planting, experiments having proved it a most valuable addition to the limited number of shrubs suitable for such a purpose. The appearance of the plant, with its deep, green, glossy, and somewhat succulent leaves, is most pleasing ; and as it grows freely in ordinary soil, and is readily propagated, it is to be hoped that it will receive the notice it is fairly entitled to as a valuable hardy shrub. Hibiscus syriacus.—This is one of our most valuable late autumn-flowering shrubs, and is also one of the few that can successfully battle with an impure atmosphere. In many parts of London, where the air is vitiated by emanations from factory chimneys, this pretty shrub is seen in perfect health, with plenty of foliage of the richest description, and quite a wealth of showy flowers. It grows freely in ordinary soil. It may be trimmed in at pleasure, and withstands frost perfectly. It is a shrub which town residents should plant freely, if they have a bit of ground that they want to look pretty. The Wayfaring Tree (Viburnwm Lantana).—This valuable shrub does not receive that amount of attention which its merits entitle it to. It succeeds well in some of the most filthy and smoky districts of our largest cities. It blooms with great freedom, and the flowers are succeeded by the brightest and showiest of berries, It is readily propagated, and no soil comes amiss to it. The Venetian Sumach (hus cotinus).—This is a much neglected shrub, but for general usefulness can hardly be surpassed. It is highly ornamental, whether in flower or fruit, the feathery inflor- escens rendering it of quaint and curious appearance, particularly when a well-grown plant is under notice. It is peculiarly well suited for planting in cities. A sound loam, neither too damp nor yet too dry, suits it to perfection. The Stags Horn Sumach (Rhus typhina).—This must on no account be omitted, as it is a plant of pretty and curious appearance, grows with freedom, and is as hardy as could be desired. 136 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. Leycesteria formosa is a beautiful hardy shrub, with hollow stems, large ovate leaves, and white or purplish flowers in pendulous racemes. More conspicuous than the flowers are the deep purple foliaceous bracts, which impart to the shrub a distinct and very ornamental appearance. It is a capital town plant, shooting out fresh and green after being subjected to a winter’s incessant fumes from the chimneys of the great metropolis. It is perfectly hardy, of free growth, readily propagated, and altogether a valuable shrub. The Flowering Currant (Ribes sanguineum).—Too much praise can hardly be bestowed on this handsome free-flowering shrub for the planting of town gardens and shrubberies. There it succeeds to perfection, and flowers with the greatest freedom. In early spring it breaks out fresh and strong, regardless of the noxious fumes and impure atmosphere. Well planted at first, it rarely fails, striking out its roots far and wide, and soon becoming a dense shrub of medium proportions. Nothing can well surpass it for the quantity, colour, and quality of its showy flowers, while it is the easiest of shrubs to propagate and cultivate. Skimmia japonica is a low-growing shrub that I have seen doing well in the heart of London, where smoke and other impurities of the air do not seem to affect it in the least. For beauty of flowers it is not remarkable, but as a handsome berry-bearing shrub it can well hold its own with any other. A north aspect, and half-peaty soil would seem to suit it. The Snowy Mespilus (Amelanchier Botryapium), with its racemes of white flowers and desirable outline, is a valuable shrub for ' planting in towns. The flowers are produced in early spring, when lawns and gardens look dull and cheerless. Of free growth, it succeeds in any fairly good soil, and soon forms a handsome specimen. Lilacs have few equals as town shrubs ; indeed, it would be good practice to plant these first, whatever else might follow. They succeed admirably in the worst and most smoky parts of London aud Glasgow, and there put on an appearance during early summer that it would be difficult to exceed in country gardens. Recent experiments have proved that many of the finer forms are equal to the common kind for this purpose, particularly the Siberian and Persian. All are of free growth, non-fastidious as to soil or site, and easily propagated. The Kentucky Coffee Tree (Gymnocladus canadensis) can ill be TREES AND SHRUBS FOR PLANTING IN TOWNS. 137 spared from any list of suitable subjects for the town garden, it having been proved to be an excellent plant for the purpose. The racemes of white flowers which it bears are particularly showy and interesting. The Bladder Senna (Colutea arborescens) is entitled to rank high amongst town shrubs, for it may be seen flowering and fruiting in the most smoky parts of many of our largest cities. It does well in the very centre of London, and is largely planted in Liverpool, Manchester, and Glasgow. The pretty yellow flowers, and the curious bladder-like seed-pods, are both showy and interesting, and render the plant one of the brightest shrubbery ornaments during nearly half of the year. Few soils come amiss, but it succeeds best in a warm and sunny position, and is well adapted for use as a wall plant. Phillyrea Vilmoriniana.—This has been planted largely for experimental purposes in the very heart of London, and succeeds there in such a way as to entitle it to rank first amongst shrubs for town planting. It is a shrub of neat habit, is an easy subject to deal with, and requires the least of attention. Forsythia viridissima is another deciduous shrub that can with- stand the fumes and smoke of towns. It grows with the greatest freedom in very vitiated atmospheres, each spring breaking out as fresh and green as if it were growing in a sheltered country garden. Of vigorous constitution, it grows freely, and flowers most profusely in the largest cities. Stiffish soil suits it well, but it is far from particular in that way, and stands hard trimming in of its shoots with impunity. The Strawberry Tree (Arbutus Unedo) finds a congenial home in the great metropolis, and there may be seen flourishing, where daily it is subjected to poisonous emanations from chimneys. The thick, leathery leaves seem well able to resist the worst of town air impurities, for they look as fresh and green after every shower of rain as could well be desired. As an ornamental shrub the Arbutus ranks high, the creamy flowers and straw- berry-like fruit being peculiarly rich and attractive. Any soil of good quality, but not surcharged with moisture, grows it well. The Double Furze (Ulex Europeus flore pleno) is one of our handsomest flowering shrubs, and is of great value for planting in town gardens and squares. For clothing warm and dry banks, where few other plants would succeed, furze, does remarkably 138 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. well, the foliage being thick and healthy, while the flowers are abundantly produced. It is of neat habit, and by judicious pruning may be kept to any desirable size. The Spurge Laurel (Daphne Lawreola) grows freely in many a town garden ; indeed, it is no uncommon thing to see large and well-balanced specimens where smoke and filth are the order of the day. It is a pretty evergreen shrub, of free and vigorous growth, and one that is well able to take care of itself under almost any conditions. It does well in the shade, and under the drip of other trees, though it is all the better of a sunny site, but not too exposed a situation. It is readily propagated, and young plants are usually found in quantity where old, established speci- mens abound. Cotoneasters of various kinds succeed well as town plants. All or nearly all are valuable for covering bare and unsightly objects, and as they grow well in the roughest and poorest of soils, they may be used in positions where other less accommodating subjects will hardly succeed. As ornamental plants, many of the Coton- easters are highly valuable, from their neat, glossy leaves and abundance of brightly-coloured fruit. Particular mention may be made of C. frigida, with its large clusters of scarlet berries ; C. Simonsti, with silky foliage and vermilion fruit; and our native C. vulgaris, a neat and hardy as well as free-fruiting species. Euonymus japonicus is another excellent shrub, one that succeeds admirably wherever it is planted. It bears trimming well, and so can easily be kept to any required dimensions. For free growth and a hardy nature it has few equals. It is not particular as to soil, and is an excellent dry-weather plant, easily propagated, and almost smoke-defying. The double-flowered variety of Prunus sinensis is hard to match, either for beauty of bloom or as regards its fitness for planting in our smokiest thoroughfares. In many of the worst smoke-infested districts of London and Glasgow, it and P. triloba appear in quite as good form and health as if they were growing in the open country. They are excellent hot-weather plants, for after hot and dry summers they do not seem so hard pressed as are many of what would be considered more robust subjects. Fairly good soil, and not too draughty a position, is all they need, while their after-management is of the simplest. The Almond (Amygdalus communis) and A. c. nana haye TREES AND SHRUBS FOR PLANTING IN TOWNS. 139 proved themselves to be useful plants for doing battle with the smoke and impure air of towns. They are both highly ornamental when in flower, not fastidious as to soil, and of neat habit. In and around London almonds are largely planted, as they are so ornamental, so free in flowering, and so easily managed. Of the typical A. communis there are numerous distinct varieties, in- cluding some with much larger and brighter flowers, one of the best of which is A. communis major. Kelreuteria paniculata is a very handsome shrub or small- growing tree, particularly when in flower, and it is one of the best of town plants. In many of our most smoke-infested towns—Warrington, and the outskirt districts of Liverpool and Manchester—it grows with great freedom, and produces in great abundance, during June and July, its panicles of showy yellow flowers. Although the Kelreuteria hails from China, it may be relied upon as perfectly hardy in perhaps every part of the British Isles. The Laurustinus (Viburnum Tinus) finds a congenial home in many a London garden, where it has proved itself to be a decided acquisition. It is a plant of bright appearance, and as free-flowering a subject as there is in the whole range of hardy shrubs. Cuttings inserted in sandy soil during August root freely, and soon form sturdy plants that in a couple of years are fit for transferring to their permanent quarters. Weigelia rosea and W. amabilis are both highly ornamental shrubs, of the freest growth, and well suited for planting in smoky localities. In many of the London gardens these shrubs may be seen in a satisfactory state, showing but few of the bad effects that generally attend town shrubs. Both are of simple culture, easily propagated, and not fastidious as to the soil. Deutzia scabra is another neat-growing and highly desirable plant for the town garden. It flowers, in such situations, with unusual freedom, ripening its young wood well, and showing but little traces of its struggle with the impure atmosphere. It may be trimmed in at will, is readily propagated from cuttings, and succeeds well in a great variety of soils and situations. The common Box (Suaus sempervirens) and the Tree Box (B. sempervirens arborescens) are largely used in town parks, squares, and gardens. The thick leathery foliage is well suited 140 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. for withstanding impurities in the air. The tree box thrives better than the normal plant in the heart of our largest centres of industry. The Gum Cistus (C. Jadaniferus) and the laurel-leaved form (C. lawrifolius) are two highly ornamental and perfectly hardy shrubs. The former has large white flowers, with a distinct purple blotch at the base of the petals, while the robust-growing C. laurifolius has pure white flowers. Both are excellent town plants, succeeding well even in very populous localities. Mahonia aquifolia, M. Bealii, and M. japonica all do fairly well in the town garden, but are the better of being assigned to select positions in the open. Good vegetable mould seems to suit the various species of Mahonia, and when once fairly established they grow and flower freely. All are shrubs of great beauty, the bright and showy flowers, produced in rich profusion, are followed by abundance of clusters of rich bluish-purple berries. The Japan Quince (Cydonia japonica) is one of the most beautiful shrubs with which our gardens have ever been enriched ; and from the number of fine healthy specimens that are to he found in many of our largest towns, it would thus appear to be particularly suitable for planting where soot and smoke are prevalent. The brilliant scarlet flowers, which are produced at a season when such are most in want, impart to well-grown specimens a beauty which is almost impossible to deseribe. It is perfectly hardy, not fastidious as to soil, and of free and easy growth, Hypericum Nepalense is the best of the St John’s worts for withstanding smoke, dust, and heat. It is a plant of great beauty, the bright foliage and abundance of large golden flowers placing it in the first rank as an ornamental plant. H. calycunum is also valuable for similar purposes ; while for edging to the shrubbery, or for covering bare spots, it has few equals. Euonymus japonicus and its silver and golden forms are most useful town shrubs, for they succeed well in very smoky and filthy localities. They are plants of great beauty, particularly the variegated varieties, of easy culture, and not at all particular as to soil in which they grow. Z£. radicans is a straggling, decumbent shrub, and, as it stands soot and smoke well, it is suitable for planting as a dwarf plant in the town garden and square, TREES AND SHRUBS FOR PLANTING IN TOWNS. 141 CLIMBERS. Of shrubs suitable for covering walls, trellises, and arbours, and at the same time able to resist the dire influences of smoke and soot, there are a few valuable and well-tried kinds. The Virginian Creeper (Ampelopsis hederacea) has few equals as a town plant, succeeding perfectly in the midst of our busiest centres of industry. Many instances could be pointed out where this handsome climber grows with the greatest freedom in the most impure and smoke-laden atmosphere, constantly exposed to the foul air, heat, and dust. It grows freely in any soil of ordinary quality, and soon covers a great extent of wall. The deeply-cut ornamental leaves change to a _ bright red colour in autumn, and are then particularly handsome and pleasing. The common Ivy (Hedera Helix) is, perhaps, the most valuable of all climbing plants for planting in smoke-infested localities. In some of the courts near Ludgate Hill, a district of London that is by no means free from smoke and foul air, the ivy climbs the houses to a height of 60 feet, and surprises one by its fresh appearance in such a locality. It needs no training, and will succeed admirably in soil composed largely of old mortar, stones, and the smallest quantity of loam. The Evergreen or Trumpet Honeysuckle (Lonicera sempervirens) is another shrub of great merit for town planting, as it thrives well in very confined spaces, and where the atmosphere is very impure. It is one of the handsomest of the honeysuckles, bearing a rich profusion of sweet-scented flowers in early summer, and requiring no special treatment or cultivation. It and the Virginian creeper require their young shoots to be fastened to the wall. Crategus Pyracantha is a most useful wall shrub for the town garden. It is of free growth, stands smoke well, and is one of the handsomest berry-bearing plants in cultivation. The variety known as Lelandii is, however, preferable to the normal plant, both for beauty of flowers and fruit. The Jasminum nudiflorum needs little description, as it is one of our commonest wall plants. For smoky districts it is invaluable, blooming freely when flowers are scarce, and seeming to heed but little the impurities of a town atmosphere. Of free growth, it is well worthy of extended culture, 142 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. The Vine (Vitis vinifera) must not be omitted from any list of town climbers, for it bears exposure to soot, smoke, dust, and heat in a surprising manner. In many towns it may be seen doing well, and covering large areas of wall with its large finely- divided leaves. There are several cut-leaved forms, one or two of which are, perhaps, more ornamental than the typical plant. Several other climbing wall-plants do well in large towns where excessive quantities of smoke are absent, but the above may be relied upon as those that are best suited ‘for planting where the atmosphere is constantly vitiated with impurities. ConIFEROUS TREES. Few of these, if any, succeed in a satisfactory way when constantly subjected to the impurities of a town atmosphere. Where the conditions are favourable, the Austrian pine (Pius Austriaca), Thujopsis dolabrata, deciduous cypress (Laxodium distichum), and Lawson’s cypress (Cupressus Lawsonit) do fairly well, but they are not to be recommended for general town planting. Letinospora plumosa aurea stood for five years in one of the most smoke-infested districts of Glasgow, and looked almost as well as it did when brought from the country. Oruer PLANTS. Yuccas of various species are to be highly recommended for planting, even in very smoky and confined districts. They grow with great freedom in many of the London gardens, as also in Glasgow, Liverpool, and Manchester. Irises, notably J. Ger- manica, do well even in very smoky and confined districts, as they have a marvellous recuperative power after being subjected to the heat, dust, and general impurities of a town atmosphere. Auriculas and border carnations also do fairly well, but they will not stand constant smoke and soot; and the same may be said of various species of hellebore, Virginian stock, Hranthis hyemalis, and chrysanthemums, Much may be done to keep plants fresh and healthy by free use of the watering-pot, syringe, and hose, aud also by carefully looking after insect pests, and stamping them out as they appear. The combination of adverse circumstances to be encountered in . TREES AND SHRUBS FOR PLANTING IN TOWNS. 143 growing plants in smoky towns is great indeed, and should only be engaged in when special care and attention can be bestowed on their culture and general management.

XI. Address delivered at the Thirty-eighth Annual Meeting, 4th August 1891. By Isaac Bayutey Batrour, 8c.D., M.D., F.R.S., Queen’s Botanist in Scotland, Professor of Botany in the University of Edinburgh, and Keeper of the Royal Botanic Garden. Our annual meeting, of which we to-day inaugurate the thirty- eighth, affords us the only opportunity which as a Society we have of reviewing our position with reference to the aims for the attainment of which we were incorporated, of considering how far we have progressed towards an immediate goal, and of discussing the lines along which we may hope to make further advance in the near future ; and it has appeared to me, therefore, that it would be fitting were I from this chair on this occasion to say something regarding matters which have very particularly engrossed the attention of the Representative Council of the Society during the past year, and which it is certain will demand even more attention during the forthcoming one. Into any retrospect of the work of a Society such as ours, there must always enter an element of sadness, As one anniversary after another comes round, and we measure our progress, we are conscious of gaps in the ranks of our comrades in work. Some veterans, or it may be youthful members, are no longer here to answer to the roll-call. And amongst those whom we miss at this annual meeting is one, the doyen of Scottish foresters, by whose death the Society has lost one of its oldest and most valued members. It is difficult to estimate the services which Mr William M‘Corquodale rendered to forestry and to this Society. His VOL, XIII, PART II. M 164 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY, reputation was not Scottish only, it was world-wide, and the woods under his charge at Scone had become the Mecea of those who desired to witness good forestry in this country. An original member of our Society, it may be truly said that to his indomit- able perseverance and determination we owe it that the Society lived through those early vears after birth which are fatal to many like institutions. The presentation made to him in 1878, which will be in the recollection of most of those present here to-day, and his election as an honorary member of our Society, illustrate the high estimation in which he was held by his fellow- workers ; the pages of our publications will witness to posterity his energy in behalf of, and his interest in, the progress of our Society and of forestry, and generations yet unborn will appre- ciate his skill and foresight as a practical forester. He has gone from us in the fulness of years, leaving a record of a life well and usefully spent, and the stamp thereof on the forestry of his time. If I content myself with this brief tribute, and do not refer to particulars of his life and work, it is not because I do not think I might have usefully dwelt on these, but because I think that some pen better qualified than mine may well recount the story of his life, for incorporation in the publications of our Society, as one eminently calculated to be a stimulating example to younger men. IT must not omit to notice also that in Mr John M‘Laren this Society has lost another veteran member, who did it yeoman service in its early days as an office-bearer, and died in office as a councillor. In such men as these the Society loses those whom it can ill spare, and their removal should remind the younger men of the Society that upon them is now coming the burden of the work so well carried on by the preceding generation. May they acquit themselves as well. I congratulate myself, in addressing the Society to-day, that I am able to speak in the hope that, within a very short period from now, the Society will have secured another and most important position, for which it has so long striven in its fight for the cause of forestry. I think all of you will agree with me that at no preceding time within recollection has the subject of forestry been so prominently before the public of the United Kingdom as it is at the present moment, and that not as a mere matter for discussion and talk— the time for that is past. Forestry is now within the range of ADDRESS BY THE PRESIDENT, AUGUST 4, 1891. 165 practical politics, and something must shortly be done which shall give the means for ensuring the permanent and _ progressive improvement of wood-cultivation in this country. That this is so must be a source of peculiar satisfaction to the members of this Society, which for now thirty-eight years has been crying out, unfortunately for long in unsympathetic ears, the need there is for more attention to scientific principle in the method too frequently in operation in dealing with our woods, And more than this, our Society may fairly claim that not only has it been pointing out during all these years that there is room for im- provement in forestry practice, and doing what it could to give effect to its teaching, but it has also from the first perceived that the real way to secure the betterment that is desirable is by giving to those who are to have the care and management of woodlands a knowledge of the scientific principles that underlie their work ; and has advocated the establishment of a school for forestry teaching. It is, I think, not uninteresting to trace the successive steps by which the persistent efforts of our Society ~ has enabled it to approach the goal to which it has been pushing, and which, shall I say, is all but attained to. When the Society was founded but little general interest was taken in forestry, and in the first years of its existence it had much to do to furnish evidence of the need for its creation. These were, however, the days of inflated land-values and pros- perous trade, and no indication of the depression shortly to set in warned proprietors of woodlands that ere many years the neglected trees would have to be looked to as carefully as the annual crops as a source of revenue. Gradually, however, the Society gained the confidence and interest of working foresters, and it is one of the features of the Society that it has been essentially a Society of practical men. The practical foresters of the country have been its backbone, and when the object is achieved which we all look for in the immediate future, and a Forestry School is established, it will be remembered that its institution eventuated from the efforts of practical men to obtain that education which would enable them to better their practice. With its strong following of foresters, the Society prospered, stimulating by its prizes intellectual effort on the part of its members, and all the while crying out for means of education in forestry. It was not, however, until it had reached the 166 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY, appropriate period of its life—its majority—that the Society saw a definite step taken towards the furnishing of the much-needed forestry teaching—the acquisition of Inverleith Grounds by the Town Council of Edinburgh and by the Crown to form an arboretum of the Royal Botanic Garden, and to be used for scientific instruc- tion. In the negotiations which led to this purchase, the influence of the Society made itself felt. It is now some years since the Arboretum was acquired, and some, I know, have been inclined to question whether it has fulfilled the object for which it was secured. Well, to them and to you I would say that, if as yet everything that the more sanguine expected has not come about, the institution of the Arboretum has already given considerable impetus to the cause of forestry. It has acted as a centre upon which ideas of progress could focus, and, as I shall presently point out more fully, it is destined, I hope, to satisfy in the near future the claims, in respect of teaching, which the most enthusiastic of us could urge. Following upon the establishment of the Arboretum, which had set people talking of forestry in a way they had not previously thought of doing, the Society made another important move in promoting the Forestry Exhibition the eyes of many people to the interests involved in forestry. an exhibition which opened Unfortunately, the financial result did not provide a surplus sufficient for the object the Society had in view when it entered on so large an undertaking—viz., the endowment of a system of forestry teaching in Edinburgh. But although the hopes that had been formed in this respect were not realised, the exhibition contributed largely to the advancement of interest in forestry questions, and strengthened the Society for its further efforts to obtain what it had so long sought after. Soon thereafter there came to the Society an honour, a not unmerited one—its Royal Charter. I need hardly say we are all proud of the distinction, and we are glad of it alike because it set a seal of approval upon the work done by the Society in the past, and because it gives greater weight to the endeavours of the Society in the future. I have singled out these three events in the past of the Society as worthy of special notice, and you will, I believe, share with me the opinion that they, each of them, fix important positions in our march onwards in the cause of forestry. And during all this time, what of interest in forestry elsewhere? In our own town ADDRESS BY THE PRESIDENT, AUGUST 4, 1891. 167 the Highland and Agricultural Society had been endeavouring to rouse interest in forestry by granting diplomas after examination, and proposals had been made for teaching in this country of the young foresters for the Indian Government ; but otherwise I am not aware that any society or body of individuals was interesting itself in forestry. But the effect of the work of our Society was making itself felt elsewhere, and the appointment of the Select Committee on Forestry of 1885 may, I believe, be traced to our efforts. You all know what are the proposals of that Committee. After hearing of a great deal of conflicting evidence, the Committee devised a scheme which, if carried out in all its details, would have gone far to supply what we, as a Society, have been seeking for. But, alas! five years are elapsed since the recommendations of the report appeared, and there is no sign of any action being taken on the lines laid down, and it appears as if the only result of the Forestry Committee, so far as we are concerned, will have been the temporary cessation of effort to establish independent teaching of forestry in Edinburgh in expectation of the advantages which it was hoped the deliberations of the Committee would confer. We were in this state of expectancy in 1889, when a new impetus was given to our energies by the arrival of Dr Somerville, fresh from the training he had enjoyed under the master of German scientific forestry, Professor Hartig of Munich. From the moment of his advent we have, I may say, felt that our hopes of the establishment of forestry teaching were near realisation. In Dr Somerville we had just the man required—one devoted to his subject, with full knowledge of it, ready and competent to impart his knowledge. And here you will allow me, whilst con- gratulating him on his election to the important and prominent position he now occupies, to express our sense of the great loss we have sustained in his migration to Newcastle. We all know how generously, for small pecuniary return, he worked for forestry in Edinburgh, and we recognise that it is a misfortune there was not, and is not yet, a post with sufficient remuneration attached to it to keep so good a man in Edinburgh. Let us hope that ere long conditions will be altered, and that we may yet see so admirably qualified a man as he occupying a chair of forestry in our university. The cause of forestry has benefited to a very great extent by the two short years in which Dr Somerville has worked amongst us. For so good a man there was no difficulty in instituting in 168 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. the university a lectureship in forestry, and under this appoint- ment Dr Somerville delivered complete course of lectures on forestry during the winters of 1889-90 and 1890-91. These were open to any student in the university, and I believe I am right in saying that they were the first courses of the kind delivered in the United Kingdom, and that Edinburgh has thus given the lead in forestry teaching. Dr Somerville’s work was in the main a labour of love: the fees provided a mere pittance, which of itself could not support a lecturer, and our Society therefore applied to the then recently established Board of Agriculture for a subven- tion under section 2 of the Board of Agriculture Act, 1889, in aid of the lecturer. Its application was successful, to the extent that in each of the years the lecturer received £100 out of Government funds. Dr Somerville’s labours did not, however, end with the opening up to students of the university of an avenue to a knowledge of forestry. They went further. The members of the Society will recollect that a circular sent to them last year informed them that a short course of lectures on botany and forestry for practical foresters would be given by Dr Somerville, and by the Keeper of the Royal Botanic Garden, during the winter months in the Botanic Garden. The course was opened, and twenty-two working-men were enrolled in the class—suflicient evidence, were it required, that lectures of the kind, if regularly and systematically supplied, would be greatly appreciated by a large body of men. In these ways, then, after so many years of struggling, the Society has seen, thanks in large measure to its efforts, the initiation of a system of forestry teaching, and the beginning, shall I say, of a forestry school. This is matter for hearty con- gratulation. The movements, so far as they have gone, can only be regarded as initial. I hope and believe that they mark the beginning of what is to be a permanent and flourishing forestry school. But, if this is to be so, effort is still wanting. I have endeavoured in outline to point out to you how our progress has been a gradual one, slow at times, but persistent, until, as it appears to me, we are near the goal towards which we have been striving for so long, the foundation of a forestry school. How then are we to proceed? How are we to pass beyond initiation to settled permanency 4 It is fortunate we no longer require to adopt the militant attitude in respect of the claims of our subject. The importance ADDRESS BY THE PRESIDENT, AUGUST 4, 1891. 169 of forestry is now recognised in the country, and it is unneces- sary nowadays to reiterate arguments in support of what is an accepted belief. What we have now to do is to induce those whose interest it is to encourage and foster good forestry to give practical support to the schemes by which alone it is possible to secure it. Circumstances have in a measure settled the lines upon which we must work, and the drift of events has cleared away many of the difficulties which up to a comparatively recent period beset the question of procedure. I think I shall carry you with me when I say that we must utilise, so far as may be possible, existing institutions for forestry teaching, and that our endeavour should be to graft any scheme of teaching we may consider adequate upon establishments already engaged in or adapted to cognate work, And this being so, I will go further and say that, so far as Scotland is concerned, there is now no doubt but that Edinburgh must be the seat for the first foundation on enduring lines of forestry teaching. Schemes for the creation of a forest school in a district more surrounded by forest land than is Edin- burgh are very inviting on paper, but the carrying out of any one such as has been proposed would involve a maximum of cost ; and it is open, I think, to question whether the special advantages claimed for a.school in such a site would compensate for the great additional outlay that would be incurred compared with that required by an adequate scheme in a university town such as Edinburgh. What we have to aim at in our scheme of forestry education is the inculcation of the scientific principles underlying forestry practice, illustrated by reference to practical operations. In a country such as ours, without large State forests, it is not possible to contemplate, in the meantime at least, a system of official practical training such as is compulsory on the State forester on the continent of Europe. For practical experience our men, of whatever class, must, as now, undergo apprenticeship to, or work with, men capable of instructing them in their art. But what we want to do is to raise the practice of forestry every where from the position of empirical routine, to have it practised as a science as well as an art. In connection with our aim, it is necessary even now to emphasise the point, that in any complete scheme of forestry education there are two groups of men to be provided for, for their confusion has led to frequent misconception on the part of those professing interest in forestry. 170 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. There are in the first place proprietors, land agents, factors, and others of similar position, to whom a knowledge of forestry will be of immense assistance in the performance of their duties, but who will not look to forestry as in any sense a profession, and with them may be classed those who propose to enter the forest service of the State in its higher grades in India and the colonies, and who will therefore make forestry a profession. To all these men an university education is essential. And then there is the practical forester—the man who, unless in exceptional circum- stances, cannot look to the advantages of an university education, yet whose training is a matter of national importance, as upon his skill depends the proper management of our woods and plan- tations. The subjects of study involved in the education of both sets of men are the same, but under existing conditions combination of their teaching is an impossibility. The practical point that comes up then for settlement is, how can we in Edinburgh provide for the teaching of all these men ? In the university here, a student can already obtain instruc- tion in some degree in all the sciences underlying forestry practice, and the institution of lectures on forestry has furnished opportunity for his learning their application to the practical management of woods. But a fortuitous attendance on science classes, without prospect of the application of a university test and the award of a mark of university training, does not meet the requirements of our time. What we desire is that forestry shall be recognised in the university as an applied science, on equal footing with engineering and agriculture, and that so important a subject shall not be left to the care of an unpaid lecturer—we could not always hope to have so unselfish a devotee as Dr Somerville to occupy the position—but that, like the other subjects I have men- tioned, it shall be entrusted to a professor occupying a distinct Chair of Forestry. As you are aware, this matter has been brought before the Universities Commissioners. How far they will be disposed to recognise the claims of forestry, and assent to its intro- duction in a curriculum of study, we are not able yet to say; but of this we may be assured, that the Universities Commissioners will not be prepared to provide all the money for the foundation of a chair of forestry. To this end, therefore, our energies must be directed. Already steps have been taken, not only by this Society but also by the Highland and Agricultural Society, with the purpose of raising a sum for the endowment of a chair, I see ADDRESS BY THE PRESIDENT, AUGUST 4, 1891. 171 that the secretary will, at a later period of this meeting, give you some account of what has been done, and what has to be done, in this matter, and I shall not, therefore, say more regarding it now. I would only point out the considerable sum already promised gives us hope of ultimate success. It is well that it should be known that the grant of £100 by the Board of Agriculture to the university lecturer during the past two years, has been only a temporary one, pending the result of our own efforts and the action of the Universities Commissioners, Whatever the latter may be, it seems to me that what we have already done affords evidence of the interest that is taken in forestry here, and should convince the Board of Agriculture that our local effort is deservy- ing of further and greater support from it. With the foundation of a chair of forestry in the university, and the institution of lectureships on plant-pathology and on plant-physiology, desired by the university as auxiliary to the chair of botany, we should have in Edinburgh a fairly efficient equipment for teaching the principles of forestry to those desirous of an university education. But this university teaching does not give us all we want. There is still the question of instruction for practical foresters, and in considering how this is to be secured, we are confronted with a difficulty which has always appeared an obstacle in the way of their education—that, namely, of the maintenance of the forester during the period of instruction, apart altogether from the cost of the education itself. No doubt, were such education for foresters available, there would be found employers who would consider the sum needed to educate and support their foresters an investment good enough to justify them in making it, and large-minded bene- factors might establish bursaries, through which foresters might be enabled to gain the advantage of the instruction offered to them. But these possibilities are not sufficient basis for the building up of a regular system of forestry teaching, and I am justified, I think, in saying that no scheme of education for practical foresters can hope for success unless it ensures at the same time that the forester shall be able to have sufficient for his support during the time of pupilage. Can this be accomplished in Edinburgh? I believe it to be possible by utilising the Royal Botanic Garden, and I shall now describe a scheme I have submitted to my Depart- ment, by which the difficulties referred to may be overcome. I start with the assumption that the subjects of elementary scentific education, with which it is desirable every practical 172 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. forester should have some acquaintance, are these :—chemistry, physics, meteorology, geology, surveying and mensuration, ento- mology, botany, forestry, and horticulture; and I propose that courses of lectures on these subjects should be given in the garden in the evenings, under a curriculum extending over from two to three years, the subjects being arranged so that no more than two lectures would be given in any one week. The subjects taught would, of course, be illustrated practically so far as possible. Foresters desiring to attend the course of study prescribed would be enrolled as workmen in the garden, and would receive the usual weekly wage, and they would pass regularly through the curri- culum of study, receiving the education free of charge. Of course they would have to take their part in all the work of the garden as do our employees at present. At the end of the curriculum the forester would leave the service of the garden, receiving when deserved a certificate of proficiency. It would be possible, of course, to receive only a limited number of men as garden-pupils of this kind, but others might be admitted to the advantages of the course under suitable arrangements. I have referred in the briefest manner to the proposals I have made, but you will see that the gist of the whole scheme is that, whilst the forester gives his labour, which will be paid for at the normal rate, he will receive education in the scientific principles of his work, free of charge to himself. The scheme is one that could be carried into effect at a very small annual expenditure. The existing equipment for teaching at the garden furnishes most of what is required in this respect. The payment of the lecturers would be the chief item of expense, and for the amount required, not more than £150 per annum, I look to Government, and have reason to be hopeful for the success of the application that has been made. In placing these proposals before this assembly of practical men, I venture to think that they are of a nature which will commend themselves to them, and that if carried into effect they will solve in a satisfactory manner the question of the education of the practical forester in the scientific principles of his work. They will not replace his practical training as a forester—I beg of you to remember that—for actual experience in the management of woods he will have as heretofore to learn under an expert forester. Were such a scheme inaugurated, we should have the Botanic ADDRESS BY THE PRESIDENT, AUGUST 4, 1891. 173 Garden and Arboretum at last established as a centre of forestry teaching, and realising the expectations formulated now many years ago of their possible future. In conjunction with the work carried on in the University, the development of teaching such as I have sketched at the Botanic Garden, would complete the Edinburgh Forestry School, the creation of which would be a lasting monument to the determination and indomitable persever- ance of the members of this Society—the practical foresters of Scotland. Gentlemen, I have endeavoured to lead up by reference to the past of this Society to the position it occupies at present with reference to the question of the development of forestry in this country. I trust I have made clear to you that whilst we may congratulate ourselves on what has been done in the past, and may look hopefully to the future, yet our hopefulness must rest on our determination to succeed in what we have set our hands to do. Because we are so near the attainment of what we have worked for so long, we must not allow our efforts to relax, but rather with redoubled energy continue our struggle, with the intent that before another anniversary meeting comes round we may possibly crown our work of thirty-nine years with the success it deserves. 174 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. XII. Introduction to Course of Forestry Lectures, Edinburgh University, Session 1891-92. By Colonel Batney, R.E., University Lecturer; Conservator of Forests, and Director of the Indian Forest School; formerly Acting Inspector- General of Forests to the Government of India. In early times the greater part of the dry land was no doubt covered with trees and shrubs of various kinds, each kind flourishing and maintaining itself in the locality best suited to its special requirements. As the older trees fell to the ground, their places were taken by others of the same or of associated species, which grew up in the openings thus afforded to them, and an unbroken succession of trees and shrubs was in this manner maintained ; for at that remote period but few of those destructive agencies were at work which have raised Forestry to a science, and have led to its inclusion among the subjects to be taught at this University. What is the foremost among these destructive agencies? Unquestionably Man; and had we foresters lived in the days when his energies in this direction were most actively employed, and had we endeavoured to arrest the havoc he was committing among his natural forests, we should have found him a very difficult being to deal with. It is no doubt true that natural phenomena, such as storms of wind, have always occurred from time to time; but the forest growth would, in most cases, surely if slowly re-establish itself after each visitation, and the damage done by four-footed animals, insects, and noxious plants, such as fungi, would not be likely to make much impression on the vast extent of forest which then covered the earth’s surface. The human population of the world was small, and the requirements of man were by no means so varied and extensive as they are at present. But as population increased and civilisation advanced, the older order of things gradually and of necessity passed away; man had to extend the small patches of cultivation which were the scene of his first efforts in the art of agriculture, and he wanted timber and firewood for domestic use. He also needed grazing grounds for his flocks and herds, and much ground was permanently cleared of forest in order to satisfy his ever-growing requirements t INTRODUCTION TO COURSE OF FORESTRY LECTURES, 17 of this nature. Then in course of time he began to build better houses with larger timber; he made boats and ships; and, later on, he constructed railways, and developed numerous industries which consumed vast quantities of wood of all species, qualities, and sizes; at the same time he largely extended his cultivation and increased his flocks and herds ; and before every one of these advances, portions of the natural forest went down, and dis- appeared for ever from the face of the land. But the process was a very gradual one, extending over many centuries. It proceeded slowly at first, and not until comparatively recent times did the country begin to assume its present appearance. It is not so very long ago that the road from London to Edinburgh was an unsafe one to travel over, in consequence of the gangs of robbers who found shelter in the thick forests through which it passed. I nave no figures before me from which I can trace the progress of denudation ; but I have no doubt that a marked change com- -nenced from the time that these islands began to enter upon that narvellous development of their trades and industries, which has laced the British race in the foremost place among the nations vf the world. Do not misunderstand me to pretend that these vere changes for the worse ; you do not require me to tell you that up to a certain, and, indeed, a very advanced point, they were very much for the better. Long before this stage of development had been reached, how- ever, a time had come when it was found impossible for every one to continue to help himself with a free hand ; claims to ownership of forest and waste lands had been set up, and established by the law of Might, and some sort of restrictions had begun to be enforced. But these were quite inadequate to arrest the progress of the destruction of the natural forest, which at length reached a point at which the supply of forest produce became insufficient to meet the requirements of the population ; and measures then began to be taken not only to secure some tracts of forest from further encroachment, but also to increase the wood-bearing area by sowing and planting. But it is not to measures of this nature that many of our largest forests owe their existence at the present day. Their continued maintenance is due rather to the protection they received under strict laws for the preservation of game, than to any endeavour to guard them for the sake of the timber they could yield. The New Forest in Hampshire is a good example of this, and the same may probably 176 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. be said of the Windsor Forest, and of the Forest of Dean in Gloucestershire, as well as of others in Scotland. It will easily be understood that the countries in which civilisation advanced with the most rapid strides were those from which the natural forests disappeared the soonest; and at the present time these islands have a smaller percentage of wood- producing area than is found in any other European country, with the solitary exception of Denmark. The actual proportion is as follows :— tussia, . . 40 per cent. Greece, . - 14 per cent. Sweden, . . 934 - Spain, . a re ap Norway, .

During the winter sessions, on two days in the week, in connection with forestry only. The teaching staff at the academy at the present time consists of thirteen professors and lecturers, in addition to the director. These comprise professors of physics, mineralogy and geology, chemistry, botany, and zoology, four forstmeisters as lecturers on forestal subjects, a lecturer on civil law, and two private lecturers, one on zoology and the other on field engineering. As already men- tioned, the forstmeisters have duties to perform in connection with THE FOREST SCHOOL AT EBERSWALDE, 247 the surrounding Oberforstereien, but, generally speaking, the greater part of their time is free for instruction purposes, or for the various researches which are carried on both by the practical and scientific departments of the academy, and which have resulted in many valuable and interesting reports.! As indicating the nature of these researches, the following may be cited as specimens of those carried out in the practical departments :— On the raising of seedling plants, quantities of seed required for given areas, preparation of the seed, and effects of transplanting on the growth of the plants. On the depth of the earth-covering of seeds. Trials of planting tools, seed-sowing machines, ete. Trials of germinators. On the thinning of oak, beech, Scots fir, and spruce forests. On pruning forest trees. On the behaviour and value of Douglas fir in the German forests. On the grubbing and removal of tree roots. On the comparative value of saws. On the yield of oak and beech seed. On the height growth of different species. On the proportion of branches to stem at different ages and periods of the year, etc., etc. The other experiments in connection with the scientific side are of an equally important nature, and all tend to show the great value of the work carried on at the institution in connection with forest science in all its various branches. In addition to his other duties, the director also edits a forestry periodical, which is issued monthly, and usually contains contribu- tions from the various professors and others outside the teaching staff. In his clerical duties he has the assistance of two clerks, one of whom acts as librarian. A conference is held weekly by the director and professors for the purpose of making arrangements and necessary alterations in connection with the instruction, and other business matters. At the commencement of every session a plan of study and lectures is drawn up by the director after con- sultation with his colleagues, and printed copies posted up in the lecture-rooms, etc. This plan includes two courses, in order to meet the requirements and convenience of those students who enter 1 In this work they have the assistance of seven forest assessors, who are employed chiefly in attending to the details of the experiments, and keeping the necessary records, 248 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. the academy in different years, and also to prevent the lectures overlapping. A student who wishes to do so may, however, take up any subject he chooses, independently of this plan, although those who intend to take a full course must follow it to a certain extent, otherwise they will be unable to finish their studies within the prescribed time. The average number of hours per day spent in the lecture-rooms are not more than five for the five days in the week on which lectures are given, and these are almost entirely confined to the morning in the summer session, a commencement being made at 7 a.m. A lecture which occupies more than one hour is always divided into two parts, by a break of a quarter of an hour in the middle, in order to prevent any weariness or inattention resulting from a long sitting. Great importance is attached to “‘yepetitoriums,” in which the ground of former lectures is glanced rapidly over, bringing out the most important points in the various subjects. These are given frequently during the second part of the course, so that the student may be kept up to the mark in every- thing from the beginning. The afternoons of two days in the week, and the whole of the Saturday, are devoted to excursions during the summer session, while for the students of the second course, the Wednesday also is taken up in this way. In the winter session excursions only take place on the Wednesday and Saturday. These excursions rarely occupy more than half a day, the forestry excursions being of course the longest and farthest afield. They are duly notified in the hall of the academy some few hours or days beforehand, the time and place of rendezvous and also the theme being given. The lecturer there meets the students, and a lecture lasting the best part of an hour is given if the subject is in connection with any special work or sylvicultural system, in order to explain its adoption and the conditions under which it must be modified. In the case of practical work, such as sowing or planting, the cost of the work under different methods is stated, and the older students are usually invited to show their proficiency in the work. Sometimes the excursions are of a more rambling character, and several miles have to be traversed in order to demonstrate the subject in different parts of the forest, anything met with on the way that calls for any special notice being duly observed and commented upon, At every excursion a reporter is selected from among the students, who is obliged to draw up a complete report of the excursion and the explanation given, so far as they relate to the theme. These THE FOREST SCHOOL AT EBERSWALDE. 249 reports are passed by the director, and are then pasted into a book placed in the reading-room of the academy, and prove of great value for reference, as well as for furnishing information to the students of the other course, the two courses having each a set of excursions distinct from each other, the first course excursions being of a more elementary character than those of the second. Frequent visits to the botanic garden are also made during the summer session under the professors of botany, when the various trees and shrubs are in flower, and their different characteristics pointed out, or a number of specimens may be laid down with numbers attached, and the students required to write down the names in their note- books, the professors afterwards reading out the names.! The course of study at the academy extends over two years, or four sessions, beyond which a student is not allowed to remain, except under exceptional circumstances. The summer session begins at Easter and finishes at the latter end of August. The winter session begins in October and finishes a fortnight before Easter, a week at Whitsuntide and Christmas being the only inter- sessional holidays allowed. The instruction given in these two years is very comprehensive, and includes subjects in the funda- mental, technical, and accessory branches. Under the first-named are comprised physics, meteorology and mechanics, chemistry, mineralogy and geology, botany, zoology, and mathematics. The technical subjects taken up are the history and literature of forests, position of forestry in political and rural economy, regeneration of forests, preservation and utilisation of forests and forest pro- duce, forest mensuration and valuation, forest statistics, forest politics and administration, and redemption of forest ground rights. The accessory are civil law, forest roads and timber transport, the chase and fish-breeding. The fundamental and accessory subjects are not gone into further than their bearing on forestry necessitates, while much of the former division has been imparted to the student in a general way before he reaches the academy. The conditions under which candidates for the State service are admitted to the academy are fairly strict, but are not connected 1Jn addition to these local excursions, a more protracted one, lasting about a fortnight, is undertaken at the close of the summer session of every alternate year, the locality chosen being one in which different methods of culture and varieties of soil exist which are not represented in the vicinity of the academy. 250 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. with competitive examinations. The candidate must possess certificates of having passed satisfactorily through a gymnasium or high school under the control of the State, and special proficiency must have been shown by him in mathematics. He must have served an apprenticeship of at least one year under a State forester, and show the necessary certificates of the same. He must have led a blameless and strictly moral life, and possess medical testi- mony in regard to his physical soundness and constitution. He must not be above twenty-five years of age at the time his studies at the academy begin. He must furnish proof of his possession of sufficient means to bear the necessary expenses of his course at the - academy. And further, he must have already passed a session or so at some university, have served his term of military service, and, in addition to his apprenticeship, have passed a certain time in the forests employed in the various work connected with wood-measur- ing, surveying, levelling, etc., special importance being attached to the two latter subjects. He may either go through the whole course at the academy, or he may spend one year at Eberswalde and the other at Munden, the plan of instruction at both academies being so adjusted as to render this course available without great inconvenience, and is recommended by the authorities, as, although the theoretical and scientific instruction is practically the same at both, the different districts in which they are situated furnish a variety of practical work and methods for the excursions. After the necessary certificates, etc., have been produced by the candidate, he receives a matriculation ticket from the director, which he is required to carry about with him at all times, and to produce if necessary. This ticket must be given up again before the student leaves the academy, and if he should happen to lose it, must apply for a fresh one at once. At the commencement of his studies he has also to fill in a form with the subjects he intends to take up during the session, which must then be signed by the respective professors both at the commencement and end of the session or course, the date on which the respective signatures were made being also entered. ‘This form takes the place of a roll- call, the regular attendance being left to the student’s common sense.! 1 The matriculation fee for State candidates and all others intending to take the full course is fifteen marks, while the fees for the whole lectures are seventy-five marks each session, or less if only a portion of the lectures are taken. Hospitanten who are admitted to the academy pay a matriculation THE FOREST SCHOOL AT EBERSWALDE. Oi The students find their own lodgings in the town, but are obliged to conform to the rules of the academy drawn up for their control by the director, although they are rather precautionary than intended for strict observance. He must notify his address to the director within twenty-four hours after receiving his matriculation card, and this address is inserted in a list opposite his name, which lies in the reading-room. The life of the forest student is in almost every respect similar to that led at any of our Scottish universities, and is, generally speaking, a very pleasant one. The majority wear the forest uniform, consisting of light green tunic and trousers and dark green peaked cap, but its adoption is quite optional, and must be provided at the student’s expense. At the expiration of the two years’ course at the academy the candidate has another session to pass at some university before being allowed to stand for the first forestal examination which takes place at the academy, and embraces the majority of the subjects in which instruction has been given. It is held bya special commission appointed by the Minister of Agriculture, and is both written and oral, and also practical, the latter taking place in the forest. The passing of this examination ranks the candidate as a “‘ Forest referendar,” and in the event of his failing to pass, he is allowed to come up again the following year, but if failing to pass within two years after the first attempt, he is excluded from further probation. Before being admitted to this examination, he has also to produce a special plan of not less than 100 hectares of forest, a working plan of 500 hectares, and a lineal section 2 kilo- metres in length, all prepared by himself without assistance. The next move that he is obliged to make is to get himself placed under a. State forester for two years further practice. The first six months of this period are passed in the performance of all the duties connected with the practical management and superintend- ence of forest operations, under the direction of the Oberforster of the division he is in. The next five months are passed in the same division ; but during this period he has complete control over the superintendence, and receives no assistance from, and ig not interfered with by, the Oberforster, unless exceptional causes for such arise. The succeeding four months are passed in work fee of ten marks for every session, and the same fees for the lectures as the other students. These fees are paid into the academy bureau, the professors having nothing whatever to do with them, either directly or as a portion of their salaries, 252 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. connected with the higher branches of forest administration, as the preparation of working plans, valuations, ete. The remaining period of his training is passed under different Oberforsters in the same sort of work, and he is then, seven years after commencing his forestal training, allowed to stand for the State examination, after passing which he becomes ‘ Forest assessor,” and practically enters the forest service as a salaried officer. During his last two years probation he must keep a diary of his daily work and occupation, noting the division which he was in, and also any special incident that came under his observation. This diary must be inspected and signed by the Oberforster before he leaves his district, and must be produced at the final examination. In addition to the above ordinary course of entering the forest service are two others connected with service in the Feld and Foot-Jager Corps. The former course involves a seven years’ service in the Feld-Jager Corps after the yearly apprenticeship in the forest, the corps being stationed in the town of Eberswalde, so that the necessary facilities for receiving the instruction at the academy are present. The members are provided with free quarters and firing, their other necessities they must furnish themselves, the ability to do which they must furnish proof of before their admis- sion to the corps. In the case of the Foot-Jager the military service is shorter, and the conditions somewhat different, but in both cases the service, or part of it, counts as student time in qualifying for the examinations, the latter being the same in all three cases. Such is a brief outline of the training to which the aspirant for forest service in Prussia is subjected, and it is rather surprising that so many are found willing to pass through it, in consideration of the comparatively small remuneration given at the end of it. The advantages are, however, greater than would appear at first sight. In the first place, the life of the forest officer is not one of very severe work, either physically or mentally, and has many attractions for a lover of sport. Everything in connection with the administrative duties are all cut and dried, it may almost be said, years beforehand, while the formule for the necessary revisions and alterations in the working plans, etc., have been well instilled into him during his long training. He has the results of centuries of observation and research at his finger ends, and scarcely a con- tingency can arise but what he has already been warned of its liability to occur. When he takes charge of a division he finds THE FOREST SCHOOL AT EBERSWALDE. 253 everything in the same order in which he is expected to leave it, and he is not handicapped during the first few years by having to make up and overtake arrears of work, ete. The life may appear monotonous, and probably would be to one with no taste for the profession, but the conditions under which he enters the service render this almost impossible, as unless he has considerable interest in his work, the acquirement of the knowledge necessary in order to pass the examinations is almost too great a task to be undertaken. The training of the forest officer is of such a nature as to develop his powers of observation to the utmost, and his acquaintance with- the habits and life-histories of the various birds, insects, ete., and their bearing on his profession, tends to occupy his mind in a manner quite unknown to the ordinary individual. That such a thorough training is absolutely necessary is a matter of opinion, but the results which have followed it tend to prove that it is not thrown away. At first sight there is nothing remarkably striking in German forests to lead one to suppose that they are managed on the scientific principles that they are, but when the detail with which they are worked is once understood, and the minute researches which have been carried out in every branch of the science, it must be admitted that little has been left undone that the most exacting could desire. 254 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. XVII. Trees Best Adapted for Various Soils. By A. D. Wesster, Hollydale, Keston, Kent. There is, perhaps, no soil so bad or barren that may not be rendered profitable by judicious tree-planting ; but, as might be expected, there is often a great want of knowledge as to the proper kind of trees to be chosen to suit a particular soil. Where the plantations are intended mainly for profit, grouping of the trees according to soil and situation will be found the surest method of attaining such an end. In looking over a large extent of woodland one will generally be struck with the great disproportion in size of the individual trees of a species ; but it will generally be noticed that where the largest and healthiest occur the tree is usually growing upon its own soil, and is found to be flourishing at the expense of all around it. Thus the finest oaks will be found where the soil is deep and loamy, resting on clay; beech upon a calcareous gravel, resting on a bed of chalk; ash and elm on a dampish loamy gravel ; birch in a light black loam, with a gravelly substratum ; Spanish chestnut in a good loamy soil, not too damp; the mountain ash at a good elevation, in a rather light soil ; horse-chestnut in deep loam, dry at the bottom; the Scots and Corsican pines, Pinus sylvestris and P, Laricio, at fairly high altitudes, and in gravelly well-drained soils; and the Cluster and Aleppo pines (P. Pinaster and P. halepensis) in almost pure sand on the sea-coast. Some trees grow rapidly enough for a few years in almost any soil, but after a time they gradually show signs of distress, make little or no progress, and ultimately become stunted and ill- grown; or, should the soil be very unfavourable, they die outright. Instances of such are unfortunately far too common wherever one travels over the country, trees of a kind that are utterly unfitted for the particular class of soil being planted in a kind of haphazard way, and without any consideration of their individual requirements. For all practical purposes with reference to tree culture, soils, generally speaking, may be divided into six distinct classes— peaty, chalky or limey, gravelly, clayey, loamy, and such as con- tain ironstone, coal, etc.,—and so as to render the subject as concise as possible we will treat each soil separately, giving a list of the trees best suited for growing thereon. TREES BEST ADAPTED FOR VARIOUS SOILS. 255 Peat.—Few trees will succeed well on an unreclaimed peat bog, but where draining and soiling have been attended to at the out- set, the numbers that grow and produce a fair amount of valuable timber are almost without limit among our generally cultivated trees. On recently examining several large plantations that were formed eighteen years ago on deep peat, on an estate in Ulster within a few miles of Lough Neagh, a useful lesson was learnt as to the best trees for planting on this kind of soil. Previous to being planted, the peat was generally of the kind which is largely used for fuel in Ireland, deep, damp, and in some places almost a quag- mire, yielding to the tread, and unsafe to stand upon. A wide and deep ditch was opened along the lowest part of the ground, and smaller drains run at nearly right angles to the main, usually in the damper places where they were most required. This was carried out fully a year before planting, and it had a decided effect in consolidating the ground for pitting in the following autumn. In summer the heath, in many places fully a yard in length, was closely burned. Pits, about 18 inches square and nearly as deep, were then opened at 3 feet apart, and left exposed to the frost during the winter. The following March and April soiling and planting were carried on at the same time. ‘The soil used was rather stiff clayey loam brought from some distance, spadefuls of which were incorporated with the peat previous to filling the hole. The cost of preparing the ground before planting is apart from the subject of this paper, suffice it then to say that the results thus obtained warrant the recommending of such a method in connection with this class of soil. Among conifers that have proved themselves suitable for bog- planting are the Larch, Scots Pine, Common and Black Spruces (Abies excelsa and A. nigra). The Larch grows rapidly, and is perfectly free from disease ; indeed, I cannot remember having seen a trace of any of the diseases which have rendered the larch so precarious a tree in this country. In thinning a larch planta- tion of fully sixty years’ growth I found the trees felled to be perfectly healthy, and of exceptional quality, with on an average 72 feet of wood in each. The subsoil was clay, and the bog previous to being planted had been cut over for fuel. Drainage and soiling of the pits had been duly attended to. In young larch plantations on deep peat bog, previously drained and soiled in the way above described, I have found the cubic contents to be 256 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. fully 2} feet in eighteen years. The Scots pine grows almost as fast as the larch—the average in over fifty trees measured being about an eighth less—under similar conditions. Natural reproduction of the Scots pine goes on so rapidly on peat bog that it must be considered one of the very best trees for planting on it. As an example of this I may state that five acres of partially drained peat bog on the side of a large lake in Ireland is now quite clothed with a thriving crop of self-sown Scots fir, the seeds being carried from a clump of old trees growing at a short distance away. Seeing how well the young trees were thriving, principally along the edge of the drains, I had all the damper portions of the ground thoroughly drained, with the result being that there is now a healthy crop of fast-growing trees all over the ground. In order, however, to avoid bare patches, I had a few young trees notched in here and there wherever gaps occurred. I am quite aware that the wood of Scots fir is of less value than that of the larch, but my object here is to point out the most suitable trees for growing on the soil under consideration. The Spruces are excellent trees for planting on reclaimed peat bog, where they produce a fair amount of timber, and afford excellent shelter to other trees. Of hardwoods, the Beech is one of the best for bog planting, as it grows rapidly and produces a great amount of clean timber. Several trees felled in thinning a plantation of sixty years’ growth on deep peat, resting on clay, had straight, clean stems for 30 feet, and contained 75 feet of timber. The Alder grows luxuriantly on peaty soils, and in the plantation with the beeches just referred to, the greater portion of the trees were 60 feet in height, girthed 5 feet at a yard from the ground, and showed no trace of disease. Another excellent bog tree is the Cherry, and the same may be said of the Holly. Ash and Oak are not generally of large size, nor are they always healthy on peat bog, even when it has received a great amount of attention in reclaiming. Birch, Lime, and Poplar of various kinds are all suited for planting on well-drained peat. Among the newer conifers, a large number of them are well suited for planting in reclaimed peat bog. By way of experiment, I have planted specimens of various kinds in newly formed plantations, and in nearly every case the trees have grown well, particularly when partially sheltered. Cupressus macrocarpa is one of the best, and not a whit behind it are C. Lawsoniana and C. Goveniana. Wellingtonia gigantea and Sequoia sempervirens TREES BEST ADAPTED FOR VARIOUS SOILS. 257 have done well, while Pinus Laricio and P. austriaca grow freely. I find that a large number of the recently introduced conifers do well on prepared peat bog—that is, where a quantity of loam has been incorporated with the bog, and all superfluous moisture drained away. Chalky Soils.—The Beech is peculiarly well suited for planting in chalk districts, for it will grow and produce a large quantity of timber where but a few inches of loam overlie the chalk—a fact exemplified in Holwood Park, Kent, where trees containing fully 200 cubic feet of wood, with stems girthing over 20 feet, may be seen. It is a fact that, in order to find where the chalk beds lie, one has only to be guided by the line traced out by the _ largest and most luxuriant beeches. As to planting the beech on pure chalk, or where no surface soil exists, I would not think of doing so, at least if the production of timber was of importance. The beech will no doubt grow on pure chalk; but where we have noticed it doing best is where loam, from 1 foot to 3 feet in depth, overlies the chalk, or is incorporated with it. In several instances that have come under my notice lately in stubbing out old field boundaries, this was the only hardwood tree that had attained to a respectable size of the many natural or planted kinds; but in some parts the chalk cropped through, while no part had more than 3 or 4 inches of loam or clay overlying the chalk. The Norway Maple (Acer platanoides) revels in a chalky soil, and so does A. colchicum rubrum, which are both handsome, hardy, large-growing trees, and well suited for extensive forest planting under certain conditions of soil. White Poplar (Populus alba) is an excellent tree for planting in chalky districts—indeed it is surprising to see to what an immense size it attains on almost pure chalk. Where but little soil covers the chalk, however, it does not attain to so large dimensions as where there is a depth of 2 feet or so; but it will grow to a fair size even on the hard, dry chalk, where a particle of soil is scarcely seen. Other poplars that do almost equally well on the chalk formation are P. monilifera and P, canadensis, both excellent free-growing trees. Elms, particularly the Huntingdon and the American, grow rapidly, and attain to a large size, where but a small quantity of loam is present in the chalk. The Wych elm grows freely in chalky districts, and I was surprised, some days ago, to notice it growing on the side of a chalk pit in only 7 inches of gravelly loam. The Lime grows very freely, and attains to large size, 258 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY, where chalk abounds in the soil. False Acacia (Robinia Pseud- acacia) is an excellent tree for chalky soils, and there attains a greater size than on almost the richest of loams. The alder and birch also thrive with vigour on chalky soils, Indeed, most trees which in a state of nature grow in damp or marshy soils are well suited for planting where chalk is the main component of the soil, and this is explained as follows:—Chalk, although sufficiently porous to allow water to percolate through it, has, like all other calcareous matter, a strong attraction for water, and acts like a sponge in holding it in considerable quantity for a very long time. The alder is very largely grown in the southern counties, par- ticularly in Kent, for hop poles, and I have been surprised at its luxuriant growth on the warm chalk. Among the conifers that are suitable for chalky soils the Spanish Fir (Abies Pinsapo) is one of the best. In the chalky districts of Kent it thrives with unusual luxuriance. At the Rookery, near the village of Downe, we were shown, the other day, some of the largest trees of the Spanish fir that we have ever seen. The largest was fully 60 feet in height, with a beautifully rounded tapering stem, girthing at 3 feet and 5 feet from the ground 7 feet 10 inches and 7 feet respectively. From base to tip this symmetrical tree is thickly furnished with branches, whose diameter of spread where they sweep the greensward is exactly 35 feet. The bole contains 69 feet of timber. When we consider that the Spanish fir was only introduced in 1839, or little over fifty years ago, it must be admitted that the specimen whose dimensions we have just recorded has made no bad use of its time. The upward rate of growth has been about 15 inches annually, assuming it was planted in the year it was introduced, and the annual increment of wood fully 1 foot 3 inches. The soil on which this fine tree is growing is a sandy loam mingled with chalk, resting on pure chalk, while the situation is fully exposed to the worst winds of the district. Nota hundred yards from this specimen grows another of almost similar dimensions, the bole of which girths 5 feet 11 inches at 3 feet up, while the branches cover a diameter of nearly 30 feet. The same bright, healthy look characterises both trees, while the luxuriant foliage, particularly of the latter, quite hides the stem from view. In various other Kentish gardens, where only a few inches of loam overlie the chalk, I have noticed how rapidly the Spanish fir grows, and how healthy and bright is the abundantly produced TREES BEST ADAPTED FOR VARIOUS SOILS. 259 foliage. In districts with not a particle of lime in the soil I have noticed this fir thriving well; but, in comparison with those growing on warm chalk or limestone soils, the differences are markedly in favour of the latter. The Mount Enos Fir (Abzes cephalonica) is well adapted for growing in chalky districts. In some places where it is of unusually robust growth, the soil is little else than pure chalk, with a small admixture of loam or vegetable matter, but yet its appearance and vigorous growth are such as betoken perfect health. The number of evergreen trees that succeed on chalky soil is well known to be limited, and it is important that two such beautiful conifers as the Spanish and Mount Enos firs should there find their most con- genial home. The Weymouth Pine (Pinus Strobus) has been recommended as a suitable tree for calcareous soils, which I can corroborate, for on the chalky downs of Kent and Surrey it grows with great vigour, if partially sheltered from cold, cutting winds. The Scots pine ranks high as a tree for planting in chalky soils. Near the chalk pits at Downe, in Kent, grows a noble clump of the Scots pine. I have never seen a better example of the “survival of the fittest” than is here presented, for, nature being allowed her freedom, the strongest trees are gradually exterminating the weaker. But this is not all, for by such a course of natural treatment clean, straight, and almost branchless trees are produced, which, when compared with such as have been allowed room to develop their side branches, are vastly superior in economic value. ‘This clump of Scots pine is growing on a bed of chalk, with only a small quantity of loam on the surface. The Giant Arbor-Vite (Zhuja gigantea) is peculiarly well suited for planting in chalky soils. This beautiful, quick-growing, and valuable timber tree is fast coming to the front for forest purposes, and it is often found difficult to meet the ever-increasing demand for young plants. The American Arbor-Vitz (7’. occidentalis) also does well when planted on chalky soils, if not too dry. For forming a screen this tree is admirably adapted ; but for timber or ornamental purposes we cannot say much in its favour. The Cedar of Lebanon (Cedrus Libani) is a first-class tree for the chalk, for finer trees than those at Goodwood, in Sussex, could not be seen ; and equally fine are those at Wargrave, in Berk- shire, where only a thin Jayer of soil overlies the chalk, The VOL, XII. PART Il. s 260 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. Wellingtonia (Sequoia gigantea) is also an excellent tree for chalky soils, in which it grows with great vigour and a very healthy appearance. Gravelly and Sandy Soils.—The Corsican pine is an excellent tree for planting on gravelly soils, and some of the finest specimens in this country are found at Penrhyn Castle, in North Wales, where it grows quickly to a large size in shingly gravel, and the timber produced in such a soil is of good quality. Some years ago several trees of this kind were felled, and the timber used for various purposes on the estate with the most satisfactory results. I have always noticed its preference for deep gravelly soil, or that of a loose porous nature. One of the trees referred toe growing on such soil, had attained a height of 60 feet in thirty-four years, while the butt end was 32 inches in diameter, and at 9 feet it girthed 6 feet 2 inches. The butt was free of branches for 18 feet, and straight as an arrow, and contained exactly 40 cubic feet. This fine tree was growing on the margin of a disused gravel pit, with hardly 3 inches of decomposed vegetable matter on the surface. Other examples of an almost similar kind might be given, but suflicient has been said to prove that the Corsican pine is peculiarly suitable for planting on pure gravel. The Scots pine on poor thin gravelly soils reproduces itself so freely from seed, and grows with such vigour, that it may be considered an eXtra well-suited tree for the afforesting of thin gravelly commons and similar tracts of land. The Pinaster, or Cluster Pine, is a most valuable tree for planting either in sand or gravel, as its growth in these in many parts of the country clearly points out. The great value of this tree in reclaiming sandy tracts, both at home and abroad, has been so often described that further reference here is not required. The Aleppo pine is a good companion to the Pinaster, and grows with greatest freedom in a sandy or gravelly soil, within the influence of the sea. Gravelly soil also suits the Weymouth pine well, for we have it growing to a large size, and looking well upon it here. Judging from the specimens we have cut up, the timber appears to be of excellent quality, and largely impregnated with resin. Beech and oak both produce a fair quantity of timber on poor gravelly soil. ‘The former in particular grows here with unusual freedom on rough gravelly soil, where hardly half a foot of loam overlies the gravel. To the south of Holwood House, in Kent, TREES BEST ADAPTED FOR VARIOUS SOILS. 261 are numbers of large beech trees growing on a deep bed of gravel, overtopped by a few inches of yellow loam. Clay Soil.—The soil here referred to was genuine clay, entirely devoid of stones, and without a particle of sand or loam in it. It occurred on the slopes, and for some considerable distance from the sides, of one of the park roads on an estate in England; and as the drive was likely to be largely used by the owner of the property, the getting up of shelter and an ornamental fringe at the same time, was a matter of much importance. Pits were dug, and the soil taken out was thrown loosely up for about a month previous to planting. No fresh soil was added at time of planting. Nearly fifty kinds of trees and shrubs were used, but out of all these only about half-a-dozen are doing well, the others having gradually died out, or become so rusty and miserable-looking that their removal was compulsory. First among the trees that have succeeded is the Giant Arbor-Vite, which seems to revel in what is generally considered the most unkindly of soils. For some years after being planted the annual shoots measured 15 inches in length, and the only difference between these trees and others of the same kind planted on rich alluvial deposit was the rather paler hue of the foliage. The branches and foliage were plentifully produced, while the stems were as straight and clean as could be desired. Even at the present time, after being planted fourteen years, all the specimens are in excellent health, and seem quite at home on their exposed and clayey site. Cryptomeria japonica has likewise done well ; but there were not half so many planted of it as of the Arbor-Vite. The trees are hardly so tall as might be expected, from the number of years they have been planted; but they are bushy and well- furnished specimens. In colour of foliage these Cryptomerias are not so intense a green as others growing under more favourable conditions. Cupressus macrocarpa has done fairly well on the clay; the growth certainly has not been rapid, but for all that the general appearance of the tree is the reverse of what one might expect from the unfavourable nature of the soil. Generally speaking, the trees of this kind are bushy and picturesque, and with bright healthy foliage. he Indian Cedar (Cedrus Deodara) we have found to be peculiarly well suited for planting on a clay soil. Not only is the bright silvery tint, that is so characteristic of this cedar when well grown, discernible in these clay-grown specimens, but the rate of growth is fairly rapid, and the drooping 262 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. branchlets are shown off to perfection. Pinus austriaca has in a few instances where strong plants were used done remarkably well, the foliage being of the usual dark yew-green, and the trees well clothed with branches down to the ground. Between the groups of trees were planted clumps of ornamental shrubs, and the best of these is the double-flowered gorse (Ulex europea flore pleno). On pure clay it has grown and increased as freely as it will on a dry chalky bank, which is usually con- sidered as its natural element. These may be considered as the trees that have done best in the clayey soil under notice; a few others still exist, but their present appearance causes me to exclude them from this list. Few of the Pine tribe did well, and this may also be said of the spruces, cypresses, yews, junipers, arbutus, dogwood, cotoneasters, hollies, and others planted. It is far from advisable to plant trees or shrubs in such unkindly soil without first adding other of better quality; but it is of great value to know that there area few plants that will thrive almost in defiance of the stubborn and unkindly nature of a stiff clay soil. Ironstone Soils.—The district to which I mainly refer, and where a few trees seem to be quite at home, is on the coal and ironstone formation, where the top soil is shallow, and the subsoil consists of a loose yellowish rag that is largely impregnated with iron. In most places but a very small quantity of soil exists, and this is of the poorest description, and varying in depth according to the lie of the measure. For all this, several of our largest forest trees seem to do well, but it is principally such kinds as root deeply that succeed in the most satisfactory way, and are able to eke out an existence in such a poor and shingly soil. The Spanish Chestnut is one of the very best trees for this soil, growing with freedom, and producing a fair amount of good timber, while its appearance indicates perfect health. Birch and Beech do well, although neither of them attain to a large size. The latter reproduces itself freely from seed, and soon spreads wherever a footing can be got. Sycamore grows freely, particularly where the pan is broken up, and produces good timber. Another tree that seems perfectly at home on the coal and ironstone is the Wild Cherry, for there it grows to a fair size, flowers freely, and produces excellent timber. Larch cannot be recommended for this soil, but, in places where a small quantity of loam overlies the coal and ironstone, it grows with great freedom for a number of years, and the timber, if cut TREES BEST ADAPTED FOR VARIOUS SOILS. 263 early, is of good quality. The Spruce soon dies out, although it may, for a number of years after being planted, grow freely enough and wear a healthy appearance. Oak and Ash do fairly well, but they rarely attain to a large size or produce first-class timber. Rhododendrons almost revel in this soil, and some of the largest and healthiest are growing with their roots in close contact with the coal and ironstone. Concluding Remarks.—In conclusion, it may be pointed out that it is only by a careful selection of soil that we may expect tree-planting to be successful, and I have no hesitation in saying that many failures can be clearly traced to errors in judgment in the selection of trees for planting on particular soils. The subject is a wide and complicated one, and it must be admitted that very perplexing diversities occur with the same kinds of trees on what to all appearance is the same class of soil. There are of course other considerations beyond the soil itself which must be taken into account, such as aspect, elevation, and whether the ground is inland or on the coast. With reference to some of the newer conifers, it must be admitted that soil and situation have a wonderful influence on their successful culture, and this applies in particular to such kinds as are not perfectly hardy and liable to injury by unseasonable frost. The too common practice of selecting warm and sheltered spots is in the main to be condemned. I have on several occasions removed trees from low-lying sheltered sites to more upland breezy situations, and with marked beneficial results. Abies Webbvana and A. Pindrow when planted on warm rich soil, at a low elevation, rarely ripen their young wood sufficiently in autumn to withstand severe frost ; and as both of these trees are apt in such places to start into growth early in spring, it is the general rule that the young growths are seriously damaged. For these and other trees of a similar nature a northern aspect and fairly rich soil is to be recommended, as in such they do not start growing too early in spring, and are thereby exempt from injury. In a plantation at 950 feet above sea-level, and planted with many of the newer conifere, it is interesting to note the differences in growth between trees of the same genera. Abies Nordmanniana aud A, pectinata, the former hailing from the Crimea, do badly; while A. nobilis and A, lasiocarpa are thriving apace, and under exactly similar conditions with the former, The soil is a loose gravelly loam resting on rough, shingly gravel; and from this 264 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY, we may infer that A. nobilis and A. lasiocarpa can subsist on a drier and poorer soil than can A. Nordmanniana and A. pectinata. It may be said that A. cephalonica and A. Pinsapo are not worth growing, and in many places they are not, but when growing on limestone or chalk they are highly ornamental. The same holds good with A. Albertiana, A. Menziesti, and A. excelsa, which are rarely seen in good form except on soil of a peaty description. Everyone interested in trees and shrubs knows that there are certain kinds which in a state of nature are only found growing in a peaty soil, mixed, it may be, more or less, with sand, and any attempt to cultivate them in other soils is productive of very unsatisfactory results. Who would ever think of planting the so- called American or peat plants, Cape Heaths, and the Epacris in, say, leaf soil, gravel, or loam; or Rhododendrons where lime is present in the soil? and these facts show us that there is something in the composition of certain soils only suitable for the roots of a certain class of plants. Another curious fact is this, that when growing on certain soils the timber of one species of tree is found to be far more durable than in others. Deep loamy soil and soft peat produce timber that is usually of a second-rate description, being deficient in firmness. I have long felt convinced that a great amount of good in point- ing out the trees that are best suited for various soils and formations, might be brought about by a careful study of the geological strata. As an illustration, we are here a distance of some seventy miles inland, and at varying altitudes from 300 feet to 700 feet above sea-level. Generally speaking, the soil consists of the different strata of the middle oolite; and to determine which trees thrive best upon it would be a most interesting study, as well as of the greatest value from a forestry point of view. As this stratum runs for a considerable distance and at greatly varying elevations, it would be valuable to learn what difference in the species of trees upon the various districts of it can be noted. The variation in certain trees, say, between the Kentish rag and chalk formation, or between the coral rag and the Oxford clay, lying next to it, is very striking, and well worthy of the attention of planters in these districts. There would be little difficulty in getting together a mass of informa- tion in this way, as reports from various districts throughout the country would be of almost universal interest in affording data to planters, TREES BEST ADAPTED FOR VARIOUS SOILS.

IntrRopucToRY REMARKS. In earlier times, when there was a plethora of forest supplies, felling was carried on without any regard to the maintenance of the forest, regeneration being left entirely to nature. But by and by nature ceased to fill up the gaps caused by man’s indiscretion, and artificial means had therefore, of necessity, to be resorted to. In this country, at the present time, restocking the ground by planting is almost the only system practised. It is not from any peculiarity of soil or climate that reproduction by self-sowing is impracticable. That this is so seems evident from the fact that, wherever a plantation is formed in a situation favourable to its healthy development, when the trees are of seed-bearing age, such a quantity of seedlings spring up, whenever an opening presents itself, as would prove all-sufficient for a future crop, if only the necessary protection were afforded for their preservation and future growth. But with a superabundance of ground game, such protection, on an extensive scale, at all events, is practically impossible, On an estate in West Aberdeenshire, with which the writer is acquainted, a considerable tract of land was entirely cleared of a heavy crop of larch, Scots pine, and spruce. The work extended over a number of years, and during that time, although nothing was done to encourage them, seedlings of the kinds mentioned, along with birch, sprang up all over the ground, and would have required little artificial assistance to have restocked the plantation ; had not the bulk of them been destroyed by hares, rabbits, and sheep. -And although much of this land is again covered with thriving plantations, yet a considerable saving could have been effected had circumstances been more favourable to the growth of the self-sown trees. I may mention another instance which came under my notice more recently. Part of a small mixed hardwood and spruce plantation was cut down and immediately replanted. But rabbits were numerous, and the result was, that almost the whole of the plants were destroyed by them. After this, the ground was enclosed with wire-netting and effectually fenced against game, whereupon THE FORMATION OF PLANTATIONS, 269 a close crop of sycamore, birch, willow, alder, ash, ete.—the off- spring of surrounding trees—came up in such abundance as rendered artificial aid unnecessary. I do not think the examples I have taken are exceptional. All the broad-leaved timber trees usually cultivated in Scotland, with the exception of oak, which only ripens its seed (in Aberdeenshire, at least) in very favour- able seasons, produce abundance of seeds, which germinate readily when conveyed by natural agencies to a suitable seed-bed ; and the same can be said of Scots pine and larch. It is generally admitted that for woods which are to be per- manently maintained for economic purposes, a well-organised system of natural regeneration is most desirable, affording as it does a more compact condition in the earliest stages of growth, and hence, as a consequence, a straight clean stem, free from large lateral branches, which conditions are, to some extent, wanting in the artificially formed wood. But it is evident from what has been already noted, and for other reasons which need not here be entered upon, that such a system, however desirable, cannot in its entirety be practised in this country ; and it is clear that we must largely depend on artificial planting for the renewal of our woods. Every advantage should, however, be taken of natural growth, when such ean be preserved. Planting or sowing must, of course, be resorted to when dealing with land previously unoccupied with a crop of trees, and in the introduction of exotics. The primary object kept in view in the formation of plantations is that of profit. It has been repeatedly proved, from reliable statistics, that substantial returns can be obtained from plantations, after deducting every item of expenditure connected with their formation and management, Our foreign trade in timber may soon be attended with difficulties. Our principal sources of supply at present are Canada, and the northern part of the Continent of Europe. The United States can now do little more than supply their own wants. Owing to forest fires, and the generally wasteful system of forestry earried on in Canada, our supplies from that quarter are likely to be very much reduced in the near future. Although the forests of America are still of vast extent, the parts of them available are probably confined within comparatively narrow limits. It is only when the timber is situated in the neighbourhood of navigable rivers that it will pay to cut it for exportation, and as these are just the most suitable places for settlers to occupy, so are 270 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. they cleared out to make room for corn-growing as the population increases. At the same time, as a natural consequence, more and more timber is required for structural and other purposes within the country. The supplies of the larger-sized timber from the north of Europe are also considerably reduced. It is highly probable, therefore, that in the course of the next fifty years our supplies of timber from abroad will be very greatly curtailed. We cannot grow all the timber we require at home, but a very considerable proportion can well be produced. Large tracts of land at present worth only a few shillings per acre for grazing purposes, but which are capable of producing Scots pine and larch of the finest quality, are available for plantation purposes. Mr D. F. Mackenzie, in his address delivered at the thirty- seventh annual meeting of the Royal Scottish Arboricultural Society, put the area thus available, in Scotland alone, at no less a figure than eight million acres ; the planting and management of which he considers would give employment to forty thousand persons. Of late the home timber trade, in common with other industries, has been very much depressed, and proprietors have found con- siderable difficulty in getting a market for certain classes of forest produce. But, with a general revival of trade, prices are certain to improve. Even at present prices, land now lying comparatively waste can be made to yield, if properly planted and managed, an annual rental of from 15s. to 30s. per acre. 2, LAYING OUT THE PLANTATION. In laying off the boundary line of a plantation, the prevailing winds of the district should be carefully studied, and precautionary measures taken to counteract their destructive effects. In these latitudes, the most violent and frequent winds blow from a westerly direction. On the eastern coast of Britain, however, the most damage is done by northerly and easterly winds. The greatest breadth of the plantation should, if possible, be laid off in the face of the prevailing winds, and on the highest parts to be planted. As regards the actual form a plantation should take, the individual tastes of the owner, and other attendant circumstances, have to be considered. The best form that can be adopted on the exposed side is the convex, the tendency of which seems to be to divide and weaken the force of the storm, Straight lines are, THE FORMATION OF PLANTATIONS, HT | if possible, to be avoided; for, besides presenting an unnatural appearance in the landscape, they are less able to resist outward pressure. As a matter of convenience, however, they have often to be adopted when the plantation is formed in immediate proximity to agricultural land. Apart from esthetic considera- tions, it is immaterial what form the plantation should take on the side sheltered from the prevailing winds, The chief aim should be to give its general contour as natural an appearance as possible, in conjunction with the securing of strength to resist storms, the curves of the outline being adapted to the configuration of the ground—the convex form prevailing in rising ground, and gradually giving place to the concave, as it again recedes. I cannot agree with those who attach little or no importance to scenic effect when laying out a plantation. Much can be done to secure beauty of scenery by a suitable arrangement of even the commonest of our forest trees. Each kind possesses shades and beauties peculiarly its own. ‘To use the words of the poet Cowper, ** No tree in all the grove but has its charms, Though each its peculiar hue; paler some, And of a warmish grey; the willow such, And poplar, that with silver lines his leaf, And ash, far stretching his umbrageous arm: Of deeper green the elm, and deeper still, Lord of the woods, the long-surviving oak, Some glossy-leav’d, and shining in the sun, The maple, and the beech of oily nuts Prolific, and the lime at dewy eve Diffusing odours; not unnoted pass The sycamore, capricious in attire, Now green, now tawny, and ere autumn yet Have changed the woods, in scarlet honours bright.” A great deal can be accomplished by judicious grouping. Although it is often necessary in profitable wood culture to have a mixture of different kinds of trees in young plantations for the sake of providing suitable nurses, or for the production of timber likely to prove remunerative when removed as thinnings, there is no reason why this order should be maintained with the permanent crop. Viewed as a whole, and as a prominent object in the land- scape, a plantation will produce the best effect at every season of the year when the trees are grouped or massed together according to their several varieties and shades of foliage. 272 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 3. FENCING. It is absolutely necessary, before commencing to plant any piece of ground, to have it thoroughly fenced against sheep and cattle. Many different methods of fencing are in use at the present time, each one possessing peculiar advantages, according to the cireum- stances in which it may happen to be required. Where shelter is of importance, nothing answers so well as thorn hedges or stone dykes. In good land the thorn hedge makes a very permanent and ornamental fence. If, however, the svil is of a light character, or the situation very exposed, it will be necessary to introduce a mixture of beech, one beech to two thorns being the best proportion. The beech thrives in a much lighter soil than the thorn, and also retains its leaves during the winter. In this way, by the shelter and nursing affurded by the beech, the thorn can be successfully cultivated where otherwise it would not grow freely. The bed for the hedgerow should be thoroughly treuched, at least 18 inches deep, and all weeds and _ large stones carefully removed. If the subsoil be of a stiff or retentive nature, it should be thoroughly loosened with the pick, but in general it is not advisable to bring much of it to the surface, unless the ground is of a peaty nature, in which case it will supply the necessary mineral matter so deficient in such soils. The quality of the soil should be equalised as much as possible, that of an inferior nature being removed, and richer put in its place. In this way a more equal growth is at once secured and maintamed. ’ cine, ’ YounlI£, Gcorge, Assistant Forester, Woburn, Beds. a L , Vol AM LLL \" , a 1 a UZ Scot. Arbor S06.

By Isaac Baytey Batrour, 8c.D., M.D., F.R.S., Queen’s Botanist in Scotland, Professor of Botany in the University of Edinburgh, and Keeper of the Royal Botanic Garden. My first duty is to thank you for the honour you have done me in electing me again to preside over your meetings. The position in which you place me is one of which any scientific man might be proud, and if I do indulge such feelings, they are not unmixed with thoughts of the inadequacy of my service and of the forbearance with which you have been pleased to regard my deficiencies. In response to your request that I should during the coming year act as your President, I can only reply by assuring you that I shall continue to promote, as far as lies within my power, the interest of forestry, and the progress of this Society. In addressing to you this evening a few remarks, I must, at the outset, congratulate the Society on its prosperity. The secretary informs me that this is quite a record year for the Society in the matter of new blood; no less than fifty-five new members having been enrolled. Surely we have evidence in this of the spread of interest in the subject of forestry throughout the country, and that the efforts made by our Society are con- tinuing to operate with increasing effect in stimulating attention to the importance of our woodlands, alike from an utilitarian and from an esthetic point of view. And if our accession of strength has been so great, it is pleasant to have to state that VOL. XIII. PART III, x 302 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. losses to the Society and the cause we are all engaged in carrying on, by the death of members, are not an average, and that no forester of outstanding ability has during the past year dis- appeared from our midst. In the remarks which I had the honour to address to the Society, from this chair, on the occasion of our last annual meeting, I briefly reviewed the position of the Society with reference to, and the progress it had made towards the attain- ment of aims for the promotion of scientific forestry after which it had been so long striving, and I ventured to express the hope that before another anniversary arrived the Society would be able to look back on its past endeavours with that feeling of satisfaction, which well-spent effort begets in the successful. It is most pleasing to me to find myself able to say that the past twelve months have been fruitful of solid achievement in the cause of forestry in Scotland; and the fruition, if it has not matured so rapidly as we had looked for, and if it is not so perfect as we could picture, is yet of a kind that we may, I think, be well content to have obtained, and I venture to hope we may claim to have succeeded in laying a foundation of the scientific education of foresters in this country. It was of forestry education that I spoke in a special manner at our annual meeting last year, and to-night I shall devote the short time I ask you to allow me to occupy to the same subject, in order that I may point out what has been done during the interval in the way of furthering this vital matter. You may recollect that I laid stress on the necessity of distinguishing the education of those attending our University from that of practical foresters, and I will to-night refer to those two sides of the question of education separately, for I do not require to remind the Society that it has interested itself alike in both. University Forestry Education—We met last year with a feeling of misfortune, in that we had lost the services of Dr Somerville, who had done such yeoman service for our cause in Edinburgh; and it seemed, for some time after his migration to Newcastle, that the difficulty of filling his official post amongst us as University Lecturer on Forestry, which we all knew would be so great, was to be even greater than we had supposed. But Lieutenant-Colonel Bailey, R.E., whose name is well known to all who are familiar with the aspects of Indian forestry, an officer of ADDRESS BY THE PRESIDENT, AUGUST 9, 1892. 303 wide experience, and whose personal qualities are no less admirable than his interest in forestry, stepped at short notice into the vacant lectureship and continued the work, which DrSomerville’s departure threatened to interrupt. It will, I am sure, be the sanguine hope of every member of the Society, that, under Lieutenant- Colonel Bailey, the progress of University teaching will proceed as rapidly and as effectually as it did under Dr Somerville, and the Society will extend a most hearty and sympathetic welcome to him. To the work conducted by Lieutenant-Colonel Bailey the Board of Agriculture continued the support given previously to Dr Somerville, and until sufficient endowment is obtained for the creation of a permanent Professorship of Forestry in the University, it is to be hoped the Board of Agriculture will not refuse to grant the £100 per annum by which so much has been already done. And this brings me to the question of the Endowment Fund for a Chair of Forestry in the University, to the raising of which the Society has devoted attention. As you are aware, the Highland and Agricultural Society has interested itself in this matter, and, like this Society, has obtained some money towards the fund. The amount already promised and in hand from all sources is, I understand, about a quarter of the total sum required, if the endowment is to be such as to place the Forestry Chair on a footing equal to that of other endowed chairs in the University of like character. The secretary will, at a later period, give us details of the figures. This is not altogether so satisfactory a result as we would wish for, but I see no element therein of discouragement. What I would say, and I believe you will all join me in saying it, is, we must get the money to endow the chair. For this purpose our efforts must be redoubled, and we must, in every possible way, endeavour to bring before those to whom good forestry is a matter of solid importance, the claims which forestry teaching in the University has upon them. A joint circular has been drawn up by the two Societies, this one and the Highland and Agricultural Society, and is to be issued at once. Let me, on behalf of this Society, ask our members to use every diligence in bringing it before those who should be willing and are able to subscribe to the fund. There is one other point bearing on university education in forestry which demands notice from me here. It is the position 304 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. of forestry side by side of others as one of education in the University. Members may remember that the Society addressed a communication to the Universities Commissioners on the subject of forestry teaching, and amongst the points urged upon their attention was the inclusion of forestry amongst subjects qualifying for a science degree. In a certain measure this has been favourably considered by the commissioners. In the draft ordinance for degrees in science in agriculture, the commissioners have placed forestry as one of the subjects of study in the cur- riculum, optional, however, with two other subjects, engineering and experimental physics. But this is not enough, What we want, and must have, is that it shall be compulsory, and I am not without hope that representations may be suc- cessful in securing the assignment to forestry of an essential place in the curriculum, a place which I do not think can be rightly denied to it. However this may be, there is ground for our expression of satisfaction, that the claims of our subject have been so far recognised by the Universities Commis- sioners. If their full recognition is not to be yet, time and organisation of the teaching of the subject will certainly bring it about. You will gather, then, that we have made some advance during the past year in pressing towards the development of university teaching of forestry in Edinburgh. We have not yet surmounted all the obstacles that stand between us and the realisation of our ideal; let us put even more energy into our endeavours and carry them to full success. I turn now to the Teaching of Practical Foresters. With regard to this the only point for dissatisfaction is the delay that has taken place in establishing the scheme which I unfolded in the remarks I made to the Society last year. By a notice in the Scotsman a few days ago, all of you will have learned that the scheme has been sanctioned, and the money required under it is now at our disposal. We may, I think, fairly exult over this achievement. We have now the means, in response to prolonged efforts, of providing for the education of foresters in the science underlying their profession, The day of carrying out the education of practical foresters has come, and as in the past we have shoulder to shoulder fought our battle for means of education, and have succeeded, so now we must in like manner ADDRESS BY THE PRESIDENT, AUGUST 9, 1892. 305 co-operate to make the working of the scheme of education a practical success. You know the essence of the scheme. Whilst educating foresters in the necessary sciences, work will be found for them in the Botanic Garden, and I hope elsewhere about Edinburgh. You may ask then what is to be our next step towards making _ this teaching a reality? We are all agreed, I take it, as to what we propose to do, to educate foresters in the sciences underlying their profession, and we have then two important points now to determine,—(1) When is the teaching to begin, and how is it to be conducted ? and (2) under what regulations are foresters to be admitted to the instruction ? I am glad of this opportunity to say something upon these heads, in order that through this Society young foresters through- out the country may become acquainted with our proposals :— As to the date of beginning- and the method of the course: I think October will be a convenient month in which to open the course of instruction. The present and next month are emphatically holiday months, and I should hore that by October it would be possible to arrange all preliminary matters. I have already been able to arrange for the teaching of several of the subjects proposed for the curriculum, and having secured as lecturers in several instances the assistants to the professors in the University, I am assured that the teaching will be of a most satisfactory kind. It will of course be our endeavour to make the instruction of as practical a character as possible, and the times of lecture and work will be so arranged that they will not interfere with the usual hours of labour, With regard to the second point :— Whatever rules are framed, they must be of a kind that will admit the right men, and will exclude the men who will not profit by the course. But it is not easy at the initiation of a scheme such as this to lay down definite rules, inasmuch as we have no means of estimating to what extent the opportunity we offer will, in the first instance, be taken advantage of, and it is evident that the number of men who can be taken on the staff of the Garden must be limited. But this is just one of these matters in which I look, and I am sure with justification, to the co-operation of members of the Society. This Society having given its imprimatur to the scheme, and nurserymen of Edinburgh having signified their willingness to aid in carrying it into effect, I have no doubt that a large 306 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. number of competent men, should they desire to pass through the curriculum proposed, will be able to find employment in Edinburgh enabling them to do so. There is one condition I would mention that I believe will commend itself to you as of necessity attaching to the scheme. We must insist on all men coming to the course being practical men, who have had some years’ experience. The course is designed for them, and you will agree with me in thinking that men who have not had some such experience could not profit by the teaching we propose to give to the extent that those who have had such experience would do, and this condition is an essential one. And then whilst we are, so to speak, in the dark as to the amount of interest the course will arouse, yet we all believe it will attract considerable attention, and be appreciated amongst practical foresters, and therefore we must be prepared to institute some sort of means of selection amongst those who may apply for admission to the course, should we find from the number of applicants or other cause that it is necessary to do so. Beyond this I do not see that we need go at the present in the making of regulations. How are we now to make known to those who are likely to desire to attend our course the education we offer? I think the simplest plan that could be adopted would be this,—and I propose to adopt it,—to draw up a circular, which would be submitted to members of the Society able and willing to advise upon it, embodying a sketch of the course of instruction, the method in which it is to be carried out, and the regulations under which men may be admitted to it, along with a schedule to be filied up by an applicant, which would be returnable, say, by the middle of September, This circular and schedule, when adjusted, would be issued to proprietors, foresters, and others in the country who are interested in the subject and whom we could reach. Upon all these points concerning the scheme [ should be glad to have an expression of opinion, with suggestions from any member of the Society who will be so good as to favour me with them. During the excursion of the Society, which I hope to join, there will be opportunity of informal conversation upon the questions involved, and I shall be happy to discuss them with any members who may be willing to do so. In the way I have indicated, gentlemen, I hope that before many weeks are passed the scheme we have devised for the ADDRESS BY THE PRESIDENT, AUGUST 9, 1892. 307 teaching of practical foresters may be fairly launched. Personally, I shall do my best to make the scheme a success, and I believe it has in it the germs of success, in which belief I am fortified by the approval with which it has been received by the Society. But it is well that we should bear in mind that this is only the beginning of that portion of our ideal forestry school providing for practical foresters. We must not expect to be able to create all at once a perfect school for the teaching of our science. Like the tree itself, such a school, to be sound and durable, must grow slowly. But I would venture to hope that this beginning we’ shall shortly make is the foundation of a permanent school by which all the aspirations of foresters, so long expressed by this their representative Society, may be attained; for, however it may be in other spheres of work, I think we may, looking at our progress within the recent past, regard the flowing tide as being with us, on which I trust we may be carried to the full accomplishment of the aims we have set before us, Postscriet.—The circular alluded to above was issued in the form subjoined.

Course of Instruction for Practical Foresters and Gardeners at the Royal Botanic Garden, Edinburgh. C1iRCULAR. By arrangement between the Commissioners of Her Majesty’s Works and the Board of Agriculture, a course of study in the Sciences underlying the Practice and in the Principles of Forestry and Horticulture will be instituted in the month of October of this year, at the Royal Botanic Garden, Edinburgh, for Practical Foresters and Gardeners. The curriculum will extend over two-and-a-half years, and will include the following subjects:—Chemistry, Physics, Meteorology, Geology, Surveying, and Mensuration, Entomology, Botany, Forestry, and Horticulture, and these will be taught practically as far as is possible. The curriculum will be free of charge to those who are admitted to it. The times of the classes will be arranged so as not to interfere with the usual hours of labour. No one will be admitted who has not had at least three years of practical experience in forestry or gardening, Applicants for admission must submit a recommendation and certificate of character from their employer.! 1 If an applicant happens to be out of a situation, a recommendation and certificate of character from his last employer should be submitted, 308 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. A certain number of men will be employed as members of the working staff of the Royal Botanic Garden, Edinburgh, during the period of the curriculum. Such men will serve under all the regulations in force in the Garden, and will receive the current wages of their grade. Through the co-operation of the nurserymen in Edinburgh, arrangements will be made for the employment of others in the nurseries about Edinburgh during the period of the curriculum. Those who are admitted to the curriculum will be examined from time to time upon the subjects of study, and any one who does not show satisfactory progress may be debarred from continuing the curriculum. Practical foresters and gardeners desirous of entering on the curriculum are requested to fill up the form on the other side, and to return it not later than the 5th October, along with the recommendation and certificate of character mentioned above, addressed to the Keeper, Royal Botanic Garden, Edinburgh. Should it appear to be necessary or advisable, some method of selection amongst the applicants may be adopted. Applicants will be duly informed whether or no they have been admitted to the curriculum. Isaac BAYLEY BALFouR, Keeper of the Royal Botanic Garden, Edinburgh. 15th September 1892. SCHEDULE.

Sir,—I have the honour to send the annexed prospectus (with form of application) of a Course of Instruction for Practical Foresters and Gardeners about to be instituted in this establishment, and to ask for your co-operation in making known the course to suitable men. I shall be glad to send additional application forms should you require them. I would specially invite your attention to that feature of the scheme by which it is proposed to find employment in and about Edinburgh for young ADDRESS BY THE PRESIDENT, AUGUST 9, 1892. 309 men from a distance desirous of taking advantage of the instruction offered, and in this way to enable them to support themselves during the period of study. The wage obtainable would be 17s. per week in this establishment, and about 2s. 6d. per day in nurseries, The advantages of the opportunities of study afforded by the scheme are so evident that they will probably be sufficient to induce good men to accept employment in Edinburgh at the rates mentioned, even although some diminution in their earnings is thereby involved. There is, however, the possibility that a deserving man might be called upon to make a pecuniary sacrifice in taking such employment which circumstances would not allow him to contemplate, and he might thus be precluded from attending the course. To meet such cases, and to supplement the wage obtainable, it has been suggested that the County Councils and other bodies having control of the administration of funds which could be allocated to such a purpose might, in different localities, see their way to making small grants, in the form of bursaries, to aid men desirous of working through the curriculum, and that many individual proprietors would be glad to give some additional pecuniary help to young men from their neighbourhood who wished to reap the benefit of the education offered. I therefore take the opportunity, whilst bringing under your notice the course of instruction proposed, to ask for your consideration of the sug- gestions I have mentioned, and to solicit your aid to give practical effect to them.—I have the honour to be, Sir, your obedient servant, Isaac BAYLEY BALFour. 310 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. XXI. On the Preparation of Wood Specimens for Exhibition. By GrorGe CapELL, Langley House, Surbiton, Surrey. INTRODUCTION. Some little time since I was asked by the manager of the Kimberley and South African Exhibition, which is to be held in 1892-93, to draw up for the information of his executive com- mittee some suggestions for the effective display of their woods, with the view of their being sent on afterwards to the World’s Fair at Chicago. The idea of writing a short paper on the subject has thence emanated. While I am aware that it is somewhat of a rash adventure to put forward any suggestions, or, @ fortiori, to lay down any rules which may come under the notice of members of the Royal Scottish Arboricultural Society, who knew so well how to set off their exhibits to the best advantage, and to arrange them with the best taste, in 1884, yet I trust this rashness may be viewed with indulgence. For I may be permitted to remind them that neither in the pages of their own Z'ransactions, nor in The Timber Trades’ Journal, the organ of the British timber trade, is there, so far at least as I am aware, any code of directions laid down for those who are tyros in the art. The very temerity of my attempt, therefore, will find its best excuse in the evoking—if happily it may evoke criticism and correction, and in the framing by some competent authority—of whom the Society possesses within its ranks some well-known names—of rules and regulations for general guidance and adoption. For in these days when imperialism is so constantly brought under our notice, when its demands and aspira- tions have been focussed under one great centre, the Imperial Institute, we waut to know, and we shall expect it to teach us, what are the real resources of the empire, and whence any deficiencies known to exist within the bounds of our own islands may be satisfactorily and quickly supplied. I cannot think that, so far as woods are concerned, this information has been fairly, much less exhaustively, pushed, New woods have certainly been taken into favour, notably the padouk wood— Pterocarpus indicus—of the Andaman Islands, regarding which I read in the last annual circular of a well-known firm of timber importers as under :— “ Padouk.—The supplies have been 1°446 loads, and a good business has been done. The use of this wood is steadily extend- ing. Values range from 3s, to 3s. 9d. per cubic foot.” ON THE PREPARATION OF WOOD SPECIMENS FOR EXHIBITION. 311 I fear, however, that this is the exception rather than the general rule, and that this wood owes the particular estimation in which it is held to the fact that the supplies of mahogany—a wood with which it more directly enters into competition—from Honduras, Mexico, and Cuba have been somewhat short recently. It is important, however, to notice this, because it is with special view to competition, and, wherever practicable, the substitution of British, that is Indian and Colonial, woods for those of foreign growth, that this necessity for uniformity in display is becoming more urgent. Even as I write the supply of English ash is scanty, and any really satisfactory substitute for it could at once command a market and a value. Now the exhibition of woods and timber specimens of all. sorts has before it two main objects—/irst, their interest for scientists ; second, their economic value. In the preparation of the specimens, therefore, these two objects should never be lost sight of; and in attempting to attain and illustrate them I would give the first place to Tue PREPARATION OF Forest PLANS AND CHARTS, I have elsewhere insisted upon the great usefulness of maps and plans, especially when the woods of a country which has different and sometimes sharply-defined zones, and correspondingly distinctive flora, are to be exhibited. To those who witnessed the display made by the Japanese Government at Edinburgh, or by the Government of Norway at Amsterdam, this insistence on my part may appear gratuitous. And I am aware that the Government of India, as well as our foreign neighbours, have nothing to learn regarding the usefulness of maps. Of the former, indeed, an intelligent French critic has thus written in reviewing the list of their exhibits :— “ Iiterature and General Cartography.—In my opinion this is the group which enables us to form the best judgment of the degree of perfection to which the technical value of personal administration has arrived. The Indian Forest Department has nothing to fear from the results of such criticism.” My insistence, therefore, is only advanced on the principle that gutta cavat lapidem non wi sed sepe cadendo.1 And if my 1 A drop of water hollows out a stone not by force, but by constant dripping. 312 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY humble efforts can more generally impress this view, I shall gladly underlie the charge of iteration and reiteration. To take a country with whose flora we are all more or less familiar, and which well illustrates my meaning, I append a rough Forest Chart of Switzerland. Here we have certain trees occupying with tolerable exclusiveness well-defined regions of the same country, while that country itself divides the distinctive flora of Northern Europe from the distinctive flora of Southern Europe. Such a map, of course more accurately prepared, should accompany every exhibition of wood specimens, explanatory tables being appended to show the number of trees of each sort, mature and maturing, which are or will become available in given years. We have further at a glance the position of the woods with reference to their accessibility, and the means available, whether by road or by water, for the transport of their products to an inland or sea-coast market. I should like to see such maps illustrating all the portions of the British empire, and I may perhaps be permitted to add that I should like to see such a map in an early volume of the Society’s Zransactions, which would do this good office for Scotland, which, so far as forestry is concerned, is facile princeps amongst its own immediate neighbours. PREPARATION OF Woop SPECIMENS. In regard to the size and shape of the wood specimens, of course tastes are various, quot homines, tot sententie. We have little bricks of wood carefully polished, and we have the rough unhewn product of the virgin jungle. Both have their values, and both have certainly their disadvantages, the latter to my mind preponderating. Looking to the objects I have noted above as apply- ing generally, [ would venture to limit the preparation of actual specimens to two classes with regard to their ultimate destinations, z.e., the museum of the botanist, or the timber-yard of the importer. Neither of these should, I think, be small. For scientific purposes I might admit, in deference to the opinion of others, those specimens made in book form (Fig. 1). Here the size should be not less than 12 inches by 12 by 3 inches, the bark Fig. 1. ON THE PREPARATION OF WOOD SPECIMENS FOR EXHIBITION. 313 of the tree being left on the back, and one side of the specimen should be polished and the other plain. But for ordinary purposes I prefer something larger, even in spite of its comparative unhandiness. The segments which I have in my mind, but which I regret I can only imperfectly delineate, are as shown in Fig, 2. We ert Wii ethyl = avi cM mt ra ved pat Ber Here the specimens are primarily logs or trunks of trees with the bark on, not less than 3 feet in length, and cut first across, second transversely, and third at an oblique angle sloping from the core outwards to the bark. The grain of the wood is thus exposed as subjected to these several cuts; the proportion of sap- wood to heartwood is clearly apparent-—that in some woods, for example, the Indian ebony, Diospyros melanoxylon, being very remarkable ; and the colour of the outer and inner wood is in strong contrast. The bark is, except where the wood is exposed by the above cuts, carefully preserved, while the wood itself is on one side of the line from A to B polished, the other side being left in its natural condition. This form of specimen has the further advantage of evidencing the annual growth of the tree, a subject to which I shall come later on—the concentric rings, the medullary rays, and generally the botanical structure. For the test purposes of the importer the logs or beams can hardly be too large. The most reliable results will be given, ceteris 314 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. paribus, by the largest logs, and the weight, for instance, of the cubic foot will, in some woods at any rate, be very much larger in the case of the log than in that of scantlings. The following results, for example, were obtained from beams of the Indian teak tree, Tectona grandis, which were 10 feet long by 4 inches by 6 inches. Weight per cubic foot, 45 to 50 lbs. Value of P=600. Modulus of elasticity = 5000.1 To illustrate what I have above said regarding the power results obtained from scantlings, | may mention that in the professional papers published at Roorkee, the actual weight of the teak in log was given at 50 lbs. per cubic foot, and in scantlings at only 35 lbs.—the latter having probably lost the essential oil which would be retained in the former. ILLUSTRATION OF RATE oF GROWTH. I am now brought to a consideration of the use of specimens in ascertaining the rate of growth, which is not the least interesting and instructive of their uses. For this purpose the kind of specimens I have commended, varying of course in size according to age, seems to lend itself most naturally to this part of my subject. Here again, however, we shall require explanatory tables. For we want to know the kind of soil in which the various specimens have been reared—the height above the sea-level of the forests or plantations whence they have been taken—the increment of annual growth, in fact everything that can tell us anything of the history and nature of the tree which is represented by its section. This is especially useful to the planter, whether repre- sented by an individual or by a government, who wishes to raise trees, not merely for ornament and use, but for pecuniary profit. I would make special reference in this regard to the specimens of oak shown by Sir James Campbell in 1884 as the products of the 1 Pj sult of f lay P is the result o ormula 5p: W is the weight which causes the beam to break. L = length of beam in feet between the supports. 3 = breadth of beam in inches, D = thickness of beam in inches.

For these form, for foresters, exhibits second in interest to none. I do not want to intrude upon other men’s preserves, but the official reports of the Nilambér teak plantation are common. property, and from them, not to be too diffuse, I extract the kernel for the information of my readers, as under :— I. Trees of seven years of age grown (a) On alluvial soil showed a total height of 29 feet, and a girth at breast high of 12 inches. (6) On gneiss and laterite showed a total height of 30 feet, and a mean girth of 13 inches. II. Trees of thirty years of age grown (a) On alluvial soil showed a total height of 85 feet, and a girth at breast high of 35 inches. (0) On gneiss and laterite showed a total height of 50 feet, and a girth of 24 inches. Here it is interesting to notice how rapidly after the seventh year the trees planted in alluvial soil outstripped their companions which had tapped a less congenial substrata. And it conveys a lesson to us all, that while trees will certainly grow almost any- where, they can only be grown to profit and advantage where the subsoil is suited to their respective requirements. At the risk of being tedious, but for a direct reason which will be apparent a little further on, I append a few more figures regarding the rate of growth of teak in the same plantation. The periodical annual increment of growth in trees of nine years of age was found to be 1:1 cubic feet, in trees of nineteen years 1:3 cubic feet, and in trees from nineteen to twenty-nine years 2°8 cubic feet, showing the rapid ratio of annual growth which took place after they had attained the age of nineteen years. NOMENCLATURE. I come now to a subject which may be thought unnecessary. It seems a childish matter to insist upon giving the specimens a name, for the infant does that to its playthings or to the live pets which surround it. And yet the most extraordinary, and, I may add, the most fatal mistakes have arisen from incorrect nomenclature, and 316 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. the consequent impossibility of identification. I knew of a case where a wood was highly appreciated for the natural oil it possessed, which enabled articles made from it successfully to resist intense - friction. A large consignment of this valuable wood was ordered and found to be absolutely worthless, being in fact another wood altogether. The samples of wood exhibited should bear not only the vernacular or local, and the botanical name, but also the name by which it is known to commerce. If it is not already known in the commercial world, then the name of the wood which it most resembles should be given. And in this branch of nomenclature, to give a wood a bad name is to spoil its chance of acceptance. I do not think, for example, that the market would jump at the “stinkwood” of Africa, although the tree, Oreodaphne bullata, which produces it is an excellent timber tree, and the wood is extremely useful for railway sleepers and the like. Any new wood should be launched under a good name, and if the stinkwood were rechristened the African oak, a name which it could rightfully adopt, its chance of success would at once be doubled. I have not thought it well to insist upon the fact of the wood bearing the true botanical name of the tree from which it is cut. For this goes without saying, and it would be better to leave the name out, or to place it thus,—species ?—than to give it a false name which could only be misleading. Fisres, Dyres, Gums, Resins, ETC. Lastly, I come to what are called the minor forest products. It is part of the object of an exhibition to show all the resources of the subject which it illustrates. There are many trees, such as the Canarium strictum, Pterocarpus marsupium, and a host of others, of which the gums they exude form not the least important part of their products. It cannot be said that the knowledge of these is by any means exhaustive. The importer would hail with delight any real substitute for gutta percha. However, a mere list of the fibres already known to commerce, and in a greater degree a list of those which have failed on trial to commend themselves, would in itself gratify neither my readers nor myself. These have formed pegs on which to hang the introduction of carding and cleaning machines innumerable, and the recollection of their worthlessness cannot but be painful to many who have embarked money in the attempt to establish them. ON THE PREPARATION OF WOOD SPECIMENS FOR EXHIBITION. 317 CONCLUSION. I have given my readers figures for a reason which they may not, I trust, consider presumptuous. The forester, and, I may add, the Scottish forester, is his own best teacher, and they may like to make experiments to determine the data I have above given in the case of the trees growing in their own woods. For this purpose, and to bring the matter nearer home to them, I give below very briefly some data regarding the Pinus latifolia, one of the five Indians pecies of Coniferze, in oxder that they may compare them with results they themselves may obtain from their own Pinus sylvestris, Weight per cubic foot, 27 lbs. Value of P or trans- verse strength, 906-961.1_ I would also venture to commend to their attention the yield tables for the Scots pine, calculated from the detailed measurements of 351 Scots pine woods, situated in Alsace, Baden, Bavaria, Prussia, and Saxony, and converted into English measure by Dr Schlick, C.I.E., Ph.D. These would be extremely interesting for the purposes of comparison with the results obtained in their own woods; and, with a small collection of wood specimens, each forester might have for himself a museum not less instructive, so far as it goes, than the Imperial Institute, which will count its treasures by thousands. Note.—We were told that in 1881 the number of wood specimens named, numbered, and described for India alone were 2530, belonging to 906 species and 432 genera, and the number since identified has doubtless largely increased the tale. 1 See ante, note to page 314, VOL, XIII. PART III. Y 318 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY, XXII. The Afforestation of Large Areas in the Highlands and Islands of Scotland. By W. A. Mackenzie, Strabane, Brodick, Isle of Arran. The fact of raw material being the basis upon which the wealth and prosperity of a fully peopled country depends, it behoves the rulers and leaders of the nation to put forth every possible effort to keep up the supply, in order that the workmen shall be fully employed, and thus prevent the draining of money from their own country to thatof others. In no country is this precaution more necessary than in our own, because, notwith- standing the opportunities we have for producing a large proportion of such timber as we buy in other countries, we, as a nation, take no advantage of these opportunities. The whole matter is left to individual efforts, which, from various causes, are inadequate to make more than a very slight impression on the wants of the country, by supplying marketable timber, or afforesting such portions of our waste lands as are not already so profitably employed. If the people of this country could be brought to see the importance of having the waste lands planted,—the importance not only to themselves, but to future generations,—they would make it a point of first-rate political consequence. Those who quite understand the question, and the value such a movement would be to the country, think it worthy of the consideration of statesmen of the first rank; and it certainly deserves to be laid before the people by their representatives, and made a parliamentary feature at a general election. Out of about ten millions of acres, more or less suitable for the profitable growth of timber, under a million acres are so employed, leaving for such a purpose at the disposal of Parliament, failing private enterprise, an area of about nine millions of acres. At the age of say seventy years, the timber on such an area would be worth to the country a clear sum of about £240,000,000, after paying for planting, fencing, maintenance, and interest at three per cent. on capital for thirty years, because after that age such woods, if judiciously managed, would pay all costs. But this is not all. Had it been so, it could not be supposed that the general public would evince much concern with a project which would take from fifty to seventy years to complete. ut the general community would, in a few years, receive a very direct benefit in the form of a more uniform and genial climate, while the benefit commercially to the adjoining lands would double THE AFFORESTATION OF LARGE AREAS IN THE HIGHLANDS. 319 the interest paid on cost of planting. These points are well known to most arboriculturists, and need not receive further attention here. At present, the great difficulty seems to be the want of money to carry on the work by private enterprise. But if encouraged by Government offering a subsidy of a certain sum for every acre planted in large areas, landowners would, no doubt, take advantage of such encouragement. And why should not Government encourage this industry by subsidy? just as they do steam shipping companies for carrying the mails to foreign countries, and many other schemes of national benefit. Another way to accomplish the end in view would be for Government to lease, under Act of Parliament, such lands as are not profitably occupied, leaving it in the option of the proprietor to redeem at any future period during the lease, the subjects so acquired, either at a valuation, or on paying the costs and interest up to the date of redemption. This could be carried out under the supervision of what is known as the Enclosure Commissioners, together or in connection with a School of Forestry. The work of supervision could be done by the commissioners at no additional cost to the country, and some of the practical details could be worked by, and under, the directions of the managers of the School of Forestry. A third way to effect the same purpose would be by the Government taking over all waste lands and planting them, reserving to the proprietor and his successors, power to resume the lands, together with the crops, buildings, fences, etc., on paying all the costs, and such interest as would be stipulated for in the parliamentary enactment giving such powers; or by paying to Government such a sum per annum, for a given time, as would cover capital and interest; taking care that the land could not be alienated from the present landlord and his successors, without his express consent, and that of his heirs, as is now required under the Acts of Entail. These are the brief outlines of several methods by which the Highlands and islands of Scotland could be clothed with growing timber within a reasonable time. Preparation of the Land.—The first operation is that of enclosing. This may be done in various ways—by wire on wood or iron posts, by walls built of such stones as may be found on the land, or by turf fences. The latter method has the advantage of sheltering the outer edge of the plantation for some years after 320 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. planting, and provides a nice seed-bed for broom and whin, which may be sown on the “backing” of the mound. The cost of this method varies with the situation, but on the average it would be about 9d. per running yard. Owing to the liability of the ditches to get cut up by floods, these fences should only be employed on tolerably flat ground, or along the base or top of plantations, if such is practicable. This kind of fencing is so valuable as a shelter, that it would pay to cut catch drains at short intervals to run off the water. Next to the turf fencing in usefulness is a stone-faced dyke, built on the same principle as the turf fence, stones being used for the face throughout, with the exception of the cope, which should be of turf. This fence has also an earth “ backing” with a scarcement and ditch, and the cost would be from 7d. to 10d. per lineal yard, according to circumstances. The third, and most economical method in the end, is that of wire-fencing of various kinds, the most durable being throughout made of galvanised iron. A good fence is made with T iron standards, with two | droppers between each pair of T standards. The standards should be self-fixing, or fixed in a base of Portland cement. For fixing with cement, small pits should be dug at the proper distances apart and filled up with clean broken stones, in which the standards are placed in position. When this is done, very little cement will be required for concreting the mass into a solid block. The fence should consist of five wires, the top one being a barbed wire. The cost of this fence would vary according to the kind of posts or standards employed. On wood posts it would cost about 10d. per yard, and with T iron standards and droppers, all galvanised, about ls. 3d. It is impossible to say exactly what system of fencing should be adopted in any particular case, for much depends on the position of the proposed plantation. Draining.—YVhe draining of waste lands previous to planting is a very simple operation, and comparatively inexpensive when properly carried out. The best system, in the absence of brooks or runlets, is to run a large “leader” along the lowest parts of the ground to be drained, and into this run small lateral drains, at an angle of about 75°, being careful not to have too rapid a run to cause “ cutting” in floods, What are known as “ well eyes” (¢.¢., where the perennial discharge of water takes place on hill-sides) should always be ‘‘tapped” by a drain, and thus avoid the cost of draining THE AFFORESTATION OF LARGE AREAS IN THE HIGHLANDS. 321] the whole “bog” formed by the spring. Land requiring to be drained can easily be detected by its wet, spongy appearance, and the vegetation with which it is covered. It is often found difficult to drain shallow basins having moorland “pan” underneath. The best and cheapest way to do this is by the use of explosives, such as tonite, which is a cheap and safe explosive. Begin the operation by driving a heavy crowbar right through the “ pan”—which is usually from a few inches to 2 feet below the surface—at every 10 yards or so, and charge the holes with the explosive. If the “ pan” be about 2 feet below the surface, a two-ounce cartridge of tonite will be sufficient to fracture the pan for a few yards around ; but for less than 2 feet of depth, an ounce cartridge will be found sufficient. The cost will not exceed 20s. per acre. The advantage of draining the “pan” by this method is that it never again unites, being so thoroughly disintegrated by the concussion that it becomes mixed up with the soil. The writer has seen the effect of this method on land where it was performed sixteen years ago, and it is still quite open and friable, with a fine crop of young timber now growing upon it. Clearing the Land for Planting.— This operation is often difficult, but cheap and effectual means can be applied to most herbage, dank grass excepted. Heath should be burned in stripes, two or more yards wide, where it is so rank as to overtop ordinary plants of either Scots fir or larch, leaving about a yard between each stripe for shelter. The burning should be from bottom to top of hills, and on level or moderately level land across the path of prevailing winds. The burning is done best in March, during dry weather and moderate winds. Fire the heath in stripes, and give a stripe to two men or lads to keep under control, and to guide the burning in any required direction. The checking of the burning is effected by what is known as “ flogging,” and for this purpose branches of spruce or Scots fir are used, or better, properly made “mops.” These are made of stripes of any old woollen material about a foot in length, tied by means of wire to hazel or ash rods, supple enough to bend, but rigid enough not to turn in the hand. Old sacks do very well. By this means there should be no difficulty in keeping the burning in check. Ifa few stripes are being burned at the same time, it is better to have a spare man or two to look after any little spark that may be lurking in the heath ready to devour the shelter stripes. The cost of this operation will depend greatly on the force of the wind, and the activity of the persons in 322 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. charge, but from 1s. to 2s. 6d. per burned acre should cover the total cost. Another kind of brushwood difficult to deal with is whins and sloes. Probably the most effective way of removing these is by horse-power, and is carried out in the following manner :—A chain is passed round each bush or clump, and is run through an “eye” link in the same manner as is done when dragging logs of wood. Two lads with a tractable horse would be able to clear a consider- able portion of land in a week ; but much would, of course, depend upon the thickness of the plants upon the ground, and no estimate can be given. Suffice it to say that the plan is found much cheaper and more effectual than grubbing by mattock, not costing one- fourth the price of the latter. Grass, particularly on damp ground, is almost an impossible obstacle to get rid of. The only effectual way to prevent choking is turfing (7.e., paring), but such grassy swards are seldom met with in situations forming the basis of this subject. Shelter.—In very exposed places this may be afforded in several ways, either artificially or naturally. By artificial I mean raising turf-dykes, or mous, such as those already mentioned; and by natural is meant shelter obtained by planting hardy trees in such positions as to break the wind. Plant either in narrow belts or in clumps throughout the entire area—elder, plane, mountain pine, and, especially in maritime districts, sea buckthorn; and except near the outside of the plantation, where the shelter must remain, in such a manner as to be removable in the course of the after- management, so as to form roads and shooting drives. Shelter- belts or clumps should be planted several years previous to planting the crop, so that they may have a hold of the ground before the young plants are put in. Artificial shelter by ridges or dykes is liable to serious objection, from the tendency of snow to form deep wreaths to their leeward, and thus large areas of plantation may be crushed down, as is often seen in upland districts. If hardy trees are planted, and whin and broom sown on the ridges, it is surprising what shelter is obtained. Another very good natural shelter is the “wattle” fence placed on exposed positions. These structures are easily and cheaply made by driving a line of stakes on the ridges, or on exposed situations, about a yard apart, taking birch, hazel, or any kind of brushwood, and weaving it roughly between the stakes and leaving it quite open to let the wind pass through, for otherwise the fences would be liable to destruction THE AFFORESTATION OF LARGE AREAS IN THE HIGHLANDS, 323 during gales. This method is only available where plenty of underwood and scrub abound. The Selection of the trees and the Mode of Planting are matters for the forester on the spot to deal with effectually, as no hard and fast rule can be laid down to suit all cases. A general rule, however, is to select the plants of a size, age, and species to suit the soil, herbage, and situation, Generally speaking, the smaller the plants are, the cheaper and more successful will be the planta- tion; and taking the Highlands broadly, two-year seedlings, one year transplanted, are the handiest and most useful plants of most of the pine tribe. So much depends, however, on the exposure and soil, that where to plant, and what to plant, must be left in the hands of the practical forester. Volumes of theory could be and are written on this subject, but to no practical effect, even from the pen of the most subtle writer; the practised eye and experi- enced judgment of the forester are the only reliable medium. Examples—and striking examples—of what the practical forester can do, if left to his own discretion, can be seen in many parts of the country, as in Strathconon near Strathpeffer, and on the Lovat and Ord estates near Beauly. As has been said above, plants should be of such species as are suitable for the different soils, altitudes, and exposures that are to be found in all extensive areas. While that is so, a general idea may here be given. In planting for profit, it may be laid down as a rule, that even in inland situations, hardwoods, such as the oak, ash, plane, and elm, should not be planted above 800 feet altitude, and only in situations highly suitable. This, however, does not refer to such of these trees as may be used in forming wind-breaks or shelter-bands for plantations of large extent. It will be found that for planting in the Highlands the pine tribe is the most suc- cessful, and therefore the most profitable; but it cannot be too strongly impressed upon planters that the smallest plants of every variety will be found to be the most profitable ; being less liable to die during the early stages of growth, and, in after years, less likely to be overturned by wind storms. In the lower situations, and where rank herbage has to be contended with, transplanted plants may be necessary, but in all situations where the herbage is of a stunted nature, two-year seedlings of all the pine tribe will be more successful. On the higher ranges, where steep gradients are met with, seeding should be resorted to, and this more especially where rocky debris prevails. In such places no preparation is necessary, 324 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. as the seed will get quickly covered by the natural process of dis- integration. As there are large areas in the Highlands highly suitable for the profitable growth of exotic conifers, these trees should be largely planted, giving Pinus monticola and other Pines light, deep, moderately dry soils; the Silver Firs, moist soils, with clayey subsoil ; and the Spruce Fir tribe, the cool damp soils, includ- ing moss. But these exotics should only be planted where the situation is naturally well sheltered. In such situations, too, in well chosen soils, the Wellingtonia gigantea and Sequoia sempervirens should find a place. Where the forester, from practical experience, can satisfy himself on the points above cited, success is almost a certainty. Planting.—There are various methods of successful planting. As a general rule the [Ta notch will be found suitable for two- year seedlings, twice transplanted, placing the plant in the slit a, which should be perpendicular to the prevailing wind. The same notch and the L notch are suitable for one-year seedlings, twice transplanted, and two-year seedlings, one year transplanted ; while the ordinary Hand-iron is the proper implement to be used for all pine seedlings, except in extremely rocky situations, in which case the pick ought to be used. As the after success of a plantation largely depends on the manner in which the planting operations are carried out, the greatest care should be taken to have the roots of the plants properly placed under the surface. Larger plants than those above named should be pitted. This latter method is very expensive, and the after results are not any better, but often worse, than what are got by seedlings and small transplants, Where afforestation can be done by cuttings of such as elder, poplar, and willow, their propagation is so easy and certain that the cuttings should be placed in their permanent position at once. The cost per acre of planting depends upon size, age, and variety of plants, together with the number of plants per acre, composition of the land, and the rate of wages in the district, and will be noticed further on. While discussing the question of planting, it will not be out of place to consider the distribution of the plants. It has been found that the grouping system is the most natural and also the most profitable arrangement. This is to be observed all over Scotland, both in natural woods and in those planted by man. Whether in natural woods it is due to the survival of the fittest I am unable to THE AFFORESTATION OF LARGE AREAS IN THE HIGHLANDS, 325 say, but the grouping system is carried out by nature with unerring precision. It is therefore better to copy nature, and assist her as far as possible, and in few things is nature more grateful for assist- ance than in the making and management of woods. The “survival of the fittest,” or mixed system of planting, is that most generally practised, on account of its being thought that if one plant will not succeed another may. Under ordinary circumstances there is a good deal to be said in favour of this plan, but it is an expensive one, and usually gives the least margin of profit during the earlier stages of thinning, It is perhaps here that the practical and thoroughly experienced forester comes to the front, and plants only what he knows will pay best. Seeding.—There are various methods by which the seeding of large areas may be accomplished, especially with birch, ash, beech, plane, elm, and pine, all of which are easily raised from seed, and more especially the birch. A cheap and very efficient plan is, searifying the surface roughly with a log of wood, having its surface covered with iron spikes about 3 inches in length and 1 inch square; the log being about 6 feet in length by 8 or 9 inches in diameter, and having at one end a bolt, swivel eye, and chain for attaching a horse. This rude implement is easily dragged through rough land, or where a thick crop of heath has been burned. With a log of an oval shape, weighing about 2 ewts., the pulling strain will not exceed 12 cwts. A man and horse with such an implement should cover a very large area in a day, giving the land a double stroke, and keeping the lines about 3 feet apart. Under favourable circumstances about 8 acres can be accomplished, but 4 to 6 acres may be considered a fair day’s work. It is an in- valuable implement for raising shelter-belts for plantations on large areas of mountain, and will prepare a good bed for the seed of birch, beech, ash, elm, and pines. The implement was suggested by seeing the effect of dragging wood through forests for lotting for sale, and observing the after results by natural seeding. The cost of the implement, with chain complete, is about 25s., and any forester could make one on being supplied with the iron spikes by a blacksmith. The spikes should be 6 inches in length, to give them a firm hold in the log. Where this implement cannot be got to work on account of the steepness of the ground, or because of boulders or rock, the mattock will be found to be best for good results. The operation with the mattock, however, is more expensive, as it will keep a man busy 326 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. to do three-quarters of an acre per day of ten hours, seeding as he goes along; but the method can be made more economical by a boy sowing the seed after every two men. Where the ground is not covered with heath or herbage to any extent, broadcast sowing may be resorted to with good effect, especially on the face of steep slopes, and among disintegrating rocks. The action of natural agencies will soon cover the most of the seeds thus sown. Sowing may be performed from January to June, according to the species, beginning with oak, mountain ash, ete., and ending with Scots elm, the seeds of which should be taken fresh from the tree about the middle of June. It requires at least ten times the number of seeds as that of plants to stock the same area of ground. On an average 2 lbs. of seed is sufficient for an imperial acre. When sown broadcast, the seeds should be mixed with some foreign substance to enable this small quantity (2 lbs.) to be properly spread over so large an area. Any friable substance will do for this purpose, provided the seeds are evenly mixed with it. Pine seeds should only be sown in the drier soils, such as those having good natural drainage, or on soils properly drained by artificial means. Cost of Planting.—The cost of planting will be more clearly understood in tabular form, taking as our basis 640 acres, or one square mile, but a larger area costs proportionately less for fencing. On each acre the following average of plants and seed should be used :—50 hardwoods, 1000 larch, 3000 Scots fir, 250 Norway spruce, 100 silver fir, and seed as per table.

On the contrary, in such places as this paper refers to, it is found that the larger the plants of the pine tribe used, the higher is the death-rate. This is due to the greater mutilation of the roots of the larger plants, parching of the plants by drying winds immediately after planting, and their liability to be shaken about and loosened by storms during the first year or two of their existence. These are facts so well known as to hardly require mentioning here; but, at the same time, while they are generally true, it sometimes happens that there may be spaces in large areas where it is necessary, from various causes, to plant larger plants than seedlings. Only where necessity demands it, however, should the system be practised. It will be readily understood that the cost of stocking some kinds of land will be more than the estimates I have given, and some will be less, according to the cost of labour and other local circumstances. It must also be borne in mind that where such large numbers of plants are required, the cost of purchasing these may be reckoned as at least 10 per cent. less than the sums stated in the tables, which have been calculated at current prices; and in the seedling class a much greater reduction may be given on large orders, If orders be given two years in advance, as much as 40 per cent. of a reduction may be allowed, and this is a point worthy of the attention of those intending to plant on a large scale. That being so, the cost of plants under No. I. system would be reduced by £285, under No. II. system by £553, and No. III. by £898—a very considerable saving on initial cost, and in every way worthy of serious consideration. It will be seen from the list of plants I have given that no note has been taken of exotics, but the reason for this is very obvious. I may say, however, that if early orders are given for these, a reduction in the price of 50 per cent. may be secured, thus lower- ing prices to a very reasonable figure. When it is borne in mind that about one hundred of these exotics are sufficient for an acre, mixed with larch, Scots fir, and silver fir, as nurses, it is not, after all, so very expensive to raise plantations of those trees in suitable soils and situations. Management for first twenty years. As to the proper manage- ment of the plantation during the period of twenty years after planting, much depends upon circumstances. Should the work be carried out in a general way, as indicated in the foregoing pages, THE AFFORESTATION OF LARGE AREAS IN THE HIGHLANDS. 329 very little will require to be done to the plantation for the first eight or ten years of its growth. The first thing necessary is to make good all deaths from whatever cause. This is more cheaply and effectually done two or three years after planting, because the blanks are then better seen. The next important point is to keep in repair fences and watercourses, artificial and natural, and this should continue till the plantation is at least twenty-five or thirty years old. At eight to ten years of age those portions of the plantation that are on the lower ground, in good soil, and otherwise under favour- able conditions, will require some thinning, or side pruning, as the case may be, the latter often being the more suitable. It need hardly be stated that the age of a plantation is no guide as to the proper time to thin, for much depends on the distance apart at which the plants were originally set, and the variety of plants, soils, and situations. Thinning should be done when the branches are beginning to interlace, and to such an extent as will allow a due amount of light and air to penetrate to all parts of the remaining plants. The least promising plants of every variety should be removed, even if those left should stand irregularly, for that can be rectified later on. When the intervening spaces are again closed up with growth, it is time to set about another thinning, and so on, till the final thinning takes place forty years or more afterwards. Hardwood plants are the better of being carefully trimmed during the first twenty years, with the pruning-knife, Prune so as to give the plants such form as may be desired. With regard to plants that may have been raised from seed, they will require earlier attention to thinning than the planted trees. This is quite natural, because under ordinary circumstances, in five or six years there will be quite a thicket of plants, on account of the way the seed was sown. The weakest plants should be pulled out by the hand, except in the case of birch seedlings, which should be cut close over, and put up into small bundles of about 20 inches in girth. These are valuable for besoms, and are much sought after for that purpose by the cleansing committees of large towns. On this account birch seeding is the most profitable, because, if properly done, it will begin to pay well about its seventh year, and will repay all costs and interest before it is twelve years old, besides leaving a heavy crop on the ground to be dealt with after that age. Before it is twenty years old half the crop may be removed for making bobbins. 330 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. It is now neeessary to give some indication of the Cost of Management of the plantation. This is difficult to do with any degree of accuracy. If there is only one area to be managed, and all of the same age, the expense will be greater than if there are several areas of different ages. Taking the area of 640 acres, and ealculating from the average of similar plantations, the whole cost of management and maintenance may be estimated at 12s. per acre, or in all about £360. The thinning at about twenty years of age should pay itself, if the plantation is situated in a good locality. This is not the case as a general rule, but what the forester and the owner have to bear in mind, irrespective of profit from thinnings, is to thin in such a manner as will prevent injury from suffocation, and allow free circulation of air and light to the soil about the roots, so as to strengthen the latter against storms, and the possibility of the trees being upset by them. This done in proper time, the success of the plantation is assured. REPORT ON PLANTATIONS ON ESTATE OF RAYNHAM, NORFOLK, 3351 XXIII. Report on the Plantations on the Estate of Raynham, Jorfolk. By ARCHIBALD GorRRIE. ! In compliance with instructions received, I inspected the various woods and plantations on the Marquis of Townshend’s estate at Raynham, in the autumn of 1874, and reported as follows on their condition and future management :— 1. Brrow Wak CLump. This is a splendid clump of fine specimens of large, healthy, and ornamental trees. Some forty trees of various kinds, large in size and of great value, have been marked for felling. When this has been done, the clump will have a much finer effect from the Hall, near which it stands. 2. Otp Nursery Woop. This plantation is composed of a rather large proportion of birch, and has been treated differently to the woods near the Hall, by removing many of the birch to make room for the more profitable trees—such as oak, ash, etc., which are very healthy and growing well. Marked 29 oak, 10 ash, 9 Spanish chestnut, and 3 silver fir for felling. 3. PLANTATION. This is in a satisfactory state, and contains many fine trees of different kinds. The rows of beech on the outside are, however, somewhat coarse. This plantation should be laid down to pasture. Marked 27 fine oak, 15 beech, 2 ash, 2 Spanish chestnut, and 1 sycamore. 4, SHEREFORD PLANTATION. This wood consists of a large quantity of valuable hardwoods— oak, Spanish chestnut, ash, beech, sycamore, etc.—besides numerous poles of various kinds. Marked 27 ash, 16 fine oak, 9 Spanish chestnut, 6 sycamore, 2 beech, and a large quantity of poles. In these four plantations are found many well-grown, lofty, and robust trees in vigorous life, and growing fast into money. The marked trees and poles when removed will realise a large sum of 1 Presented by Mr Archibald Gorrie, Brookmans Park, Hatfield, Herts. 332 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. money, and they can be well spared, with great benefit to the remaining trees. 5. THe Kitceen Woop. It is proposed to clear away as much of this wood as will square it with the west front of the Hall, as marked out by stakes on the ground. This will be a grand improvement, as it opens up a wide extent of splendid scenery. To obtain this result 60 oak, 5 Spanish chestnut, 1 sycamore, and 1 old lime tree will have to be felled. This lot, except the sycamore, should be sold to a timber merchant as it stands, who should be bound to grub-fell all the trees. I mention grub-felling in preference to the usual mode, as it is of the utmost importance that the ground should be carefully stubbed and cleared of all roots and weeds, and laid down with the best per- manent grass seeds; and thus, in addition to greatly improving the view, the value of the pasturage would also be considerably enhanced. Marked about forty fine trees in this wood outside of the line of the vista, but could not complete it owing to the abundance and strength of the underwood. Great care is necessary here to preserve only the best specimen trees, such as will improve the appearance of the lawn, and the thinning ought to extend over a period of eight or ten years, the ground to be ultimately cleared and laid down with permanent grass seeds and thrown into the adjoining pasture. The landscape would be much improved by clearing away the thorn hedge on the south side of this wood. 6. Youne KitcHen Woop. Several fine vistas from the Hall are projected through this division, and the trees to be felled carefully selected and marked. When opened up, the vistas will have a fine effect. There are some very large sycamores in this quarter, which, from injudicious pruning years ago, are unsound and fast losing value, and accordingly they are marked for conversion into money before they get to the price of firewood. Several of the best, however, are still very valuable, and will bring good prices, and their places will soon be well filled by the fine young trees that remain. 7. PLreasureE GrounD PLANTATION. This consists of various kinds of forest trees, which, for want of being properly and timely thinned, are very much crowded, drawn REPORT ON PLANTATIONS ON ESTATE OF RAYNHAM, NORFOLK. 333 up, and injured. The trees for felling have been carefully marked, so as to leave only the best specimens, and many years of careful management will be required to bring it into a perfect and profitable state. A large quantity of good larch, oak, ash, and sycamore, as also lots of poles, have been marked for felling, and all, except the oak, should be cut at once and removed before the wet weather sets in. A great improvement will be effected here, by straightening and widening the present vista towards Hardlings, as marked out. When the timber has been removed, and the ground thoroughly cleaned, levelled, and properly laid down with fine lawn grass seeds, and kept closely mown, a very marked improvement will be apparent. 8. PLEASURE GROUNDS—NEXT HARDLING Woop. Oak and beech predominate in this section, and it requires to be carefully thinned in places ; but, owing to the impenetrable growth of underwood, the trees could not be marked. 9, PLEASURE GrounDS—NursERY TO KITCHEN GARDEN. This plantation is very much drawn up and injured from over- crowding, but it has been partly thinned during the past two years. The whole has been closely inspected, and the trees marked that should be felled this winter to liberate the fine timber trees remaining. The youngest part of this wood has far too many laurels in it for either cover or ornament, and it is suggested to grub up full half of them, leaving the remainder in clumps of various sizes and shapes. This will give better cover for game, and be much more ornamental. 10, PLeasureE GrounpsS—FLOwER GARDEN TO LopGE Garter. This consists of various kinds of very fine trees, but overcrowded and drawn up, and those to be felled could not be marked owing to the thick growth of underwood. The fine Wellingtonia by the side of the walk would be much improved with the admission of more air and light. 11. Bett From Hat. To STABLES. Consists of oak, ash, elm, etc., all of which have been carefully inspected and marked, and a good view brought in from the gate and lawn in front of the Hall towards the lake. VOL, XIII. PART III, Z 334 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 12. CLuMP AT BACK OF STABLES. This has been well thinned so as to get the specimen trees to feather low, with a view to hide the stables from the road and other places. The fence round the clump might be removed with advantage. 13. STABLES AND Gas-HOoUwsE. The stable yard is very much exposed towards the church, and to the roads to the Hall, and as the buildings are without architec- tural pretensions, it is desirable to screen them by planting nine or ten trees at the spots indicated by the pegs in the ground. The young lime trees around the moat, which appear to have been planted to hide the old houses, so beautifully mantled with ivy and presenting an extremely picturesque appearance, should be transplanted to more suitable places, excepting one or two next the gas-house and four or five next the waggon lodge, as pointed out to the forester. 14. TimpeR Yarp AND Haystacks, CARPENTER’s SHOP. These should be removed from their present sites, as planting them out cannot be recommended, because it would interfere very much with a charming view of the landscape across the lake and the beautiful scenery beyond. The building now used for a carpenter’s shop is old and dilapidated, and from want of room and light it is ill adapted for men to work in. It is therefore suggested that it should be cleared away and a new one erected as near the sawmill, and as much out of view, as possible, taking care to secure a convenient site, with sufficient space for storing rough timber. If this plan is adopted, the hay can be stacked on or near the site of the present carpenter’s shop ; and then there will be no necessity to plant trees where the stakes are put in at the back of the stables, especially as every tree there planted would interfere very much in course of time with the view of much interesting scenery. By the removal of these unsightly objects the results would be in every way most satisfactory. 15. Park, NORTH SIDE OF LAKE. All along the north side of the lake there is a jumble of fine young oak, elm, beech, ete., much too thick for park trees. A REPORT ON PLANTATIONS ON ESTATE OF RAYNHAM, NORFOLK. 335 number have therefore been marked, with a view to improve both the landscape and the pasture. When they are removed it will give a fine effect from the West Raynham approach, more especially if the lake is cleaned out, as I consider that no landscape view can be reckoned complete in which water does not form a part, and when it does exist it ought always to be made the most of. 16. Harpuine’s PASTURE. This is also a perfect jumble of fine young park trees growing into one another, and require to be well opened up to show the beautiful landscape they now shut out from the West Raynham entrance. A number of trees have been marked, and when they are removed, it may be found necessary to take down more, to open up the beautiful scenery. 17. TREES NEAR THE CHURCH. Several of the trees around the church have been marked, which, when felled, will show a great improvement. I would suggest that the Irish yew in the churchyard be transplanted, or cut down, as it quite obstructs a charming view from the church door. 18. Mr Savory’s Pasture. This division is well furnished with splendid park trees, and forms a fine feature in the landscape viewed from the opposite side of the lake near the Hall. The horse-chestnuts, limes, elms, and walnuts would be difficult to match anywhere else. Marked ten trees for felling ; and great care will be necessary in marking any more, for fear of showing the village from the Hall. 19. BELT BY SIDE oF LAKE, This should be carefully thinned, and put into Mr Savory’s pasture as far as the osier bed. Great care must be taken to leave only the best of the outside trees. 20. Rounp BusH PLANTATION. Consists of oak, ash, beech, elm, etc., very much drawn up. It should be thinned gradually, with great care, every two or three years, till only the best trees are left. 336 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 21. Brick-KILN PLANTATION. This is similar to the last, and the same remarks apply. After being properly thinned, both should be put into the adjoining pastures. 22. Mr ButcHer’s Meapow, NEAR Hitt HovueGHron. Marked twenty-seven good trees in this meadow. In the corner of the meadow, next the village, are some splendid trees, in a very healthy state. 23. GALONEL FIFTEEN-ACRE PLANTATION. The middle of this wood consists of very fine old oak, ash, beech, and sycamore ; and it is recommended that several of the beech be felled, as they are interfering with the growth of the more profit- able timber. The young part of the wood is being much injured for want of thinning, and requires immediate attention to that operation. 24. Woop sy LopGE Next FAKENHAM Roap. Marked thirty trees of various kinds in this wood, leaving only the best park trees, with the view of improving the appearance of the place when the marked trees are removed. Other places require more immediate attention to thinning than this, but it should not be too long postponed, else evil will result. 25. Entrance LopGe to HALt—rFrom FAKENHAM ROAD. The beit on the right side going to the Hall has had trees marked at several points, to break up the monotony of the long even line of plantation. On the left side several trees have been marked. When these are all removed, some beautiful glimpses of scenery will be opened to view from the drive. The unsightly and inconvenient gate which crosses this approach, and the fence dividing the park, are very undesirable, and should be removed. The whole might then be pastured with sheep, if cattle are an objection near to the mansion. The appearance of the park would be very much improved thereby, and much convenience gained.

Marked thirteen trees in this clump, which has a ripe and rather stunted-in-growth appearance, and probably several more trees might be taken down. 27. Rounp CLumpe 1n Mr Case’s PASTURE. In this meadow, marked six ash and five oak trees for felling. 98. THE V PLANTATION. This plantation is getting too much drawn up, and ought to be thinned at once, although the small oaks will not pay for felling. The same remarks apply to the young clump next to it, only, as many of the Scots fir as will make gocd trees should be left, as the extensive park is deficient of evergreen trees. 29. YounaG PLANTATION FROM SHEREFORD Woop TO FAKENHAM Roap. It is to be regretted that in this extensive plantation nearly all the young trees are too much drawn up, and it is suggested that all the parts which have been thinned during the past two or three years should be gone over again immediately, leaving the Scots fir where possible, and carefully thinning out the others, The sacrifice of a little bark on the underwood is really unimportant, conipared to the great benefit that will accrue to the growing crop of timber, by timely and repeated thinning, and especially when the young trees have been previously neglected. A row of full-grown beech runs along the south side of this plantation, beginning at the Shereford end, which might be sold, as they are injuring the young trees, and they are not required for the landscape, as the young plantation would immediately take their place. There are also three rows of ash, on the park side of the plantation, opposite the beech, of which the inside row would be better removed, because if it remains it will ultimately injure the live fence. A good wide drive, or ride, from one end of this plantation to the other would be highly beneficial. It should be run as near the middle of the wood as possible, so as to be con- venient for getting out the timber, as well as for shooting and other purposes. 338 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 30. CLump NEXT Mr Bate’s PASTURE. This clump, by the side of Mr Bate’s pasture, next the Fakenham Road, is composed of fine young trees, which are, however, far too much drawn up. It should be thinned properly, and then put into Mr Bate’s pasture, as, from its proximity to the road, it cannot be of any use for cover. 31. Mitt Hitt Cover—rrom Pusiic Roap To Rose GREEN. This large young wood is chiefly composed of oak, very much crowded and drawn up. It should be treated in the same manner as recommended for No, 29—the young plantation from Shereferd Wood to the Fakenham Road.
