Beware of land subject to floods—looking and enquiring for the ~ highest point ever reached by river or lake. 4, In buying, keep the price low, and remember what the land will cost by the time it is cleaned and ploughed. The higher price is no- criterion of quality, but rather of fashion in land, where living is more expensive. 5. See outlying districts, rather than buy land which has been picked over by many before you came. 6. Remember that land fit to plant must be such as may be ploughed in any direction. Do not plant in an excess of potash, and when planted keep your ranche properly cultivated. 7. Plant only the best varieties of apples. | Dry months occur all over British Columbia, and it will be found that July and August are times when a lack of moisture will check the growth of the trees in their early stages, and in some orchards bad resulis from insufficient moisture are even now apparent. To avoid this some system on the lines given below will have to be adopted :-— — . Irmgation. . Dry cultivation. . Relying on “ seepage.”’ bo OS Irrigation is a troublesome system in an orchard, for while land is being irrigated it needs constant attention, and even then more or less bad “ wash-outs”’ will take place. In the opinion of many it detracts from the flavour of the frm srown, and it stands to reason that by this system much plant food must be washed out of the ground. Irrigation must tend to bring the roots of the trees along the line followed by the water, rather than equally distributing them around the stem, and thus less plant food is available, by limiting the area from which the tree derives its nutriment. Water in British Columbia always costs money in some way or other, and dependence on irrigation must be counted as an extra expense ; it is either put on to the price of the land, when bought, or it is collected yearly as a rent, or you find your own water supply when you “stake ” out your land and convey it to your orchard. Tt also costs money in the labour necessary while irrigation is being carried oui. Dry farming necessitates the constant stirring-of the earth, and keeping the surface of the soil dustlike in fineness, and this condition can only be arrived at by constant cultivation, which therefore means constant labour. The summer heat tends, in a climate where dry farming obtains, to the premature ripening of the fruit, and greater risks have to be incurred when an orchard is first planted. In these regions the hot summer climate is as a rule followed bya severe winter, and so there is a limitation of the varieties which can be successfully grown, and this means the elimination of the finest varieties of dessert fruit. 3 Natural moisture, or “ seepage,” can only be found in sufficient quantity to be serviceable at the foot of very high hills, thus limiting the area of cultivation and affording only small fruit-land areas near rivers and lakes. THE CULTIVATION OF FRUIT IN BRITISH COLUMBIA. 3 But this is surely the most natural way to grow fruit, as here there is no washing of soil, no loss of plant food, no extra labour. Its only drawback is the comparatively small area on which sufficient seepage can be found —namely, where the immediately surrounding hills are high enough to feed the lower lands with moisture from melting snow, and where the land is not too rocky, or liable to flood, to make fruit-growing practicable. , Reviewing the districts, each one has its peculiarities, from drought on some of the western isiands to the damp and lichens of the coast, through the hot reaches round Pentiction and Keremos, through the erstwhile land of scrub round Okanagan Lake, to the timbered lands of - West Kootenay, and on to East Kootenay’s parched valleys. Some parts are well settled and others contain only isolated ranches. In the more settled places land has risen in value until it is almost beyond the reach of the average settler, whereas in the more easterly parts it can be bought for a quarter the price—land standing in timber, it is true, but land which has supported fine forest trees, and which will support fine fruit trees if the climate is not too severe. The chosen site of nature’s forest is better suited to the growth of fruit trees than land unable at one time to support more than sage-bush and greasewood, forced out of a dryness too great for timber into an orchard grown by artificial irrigation. Heavy clearing characterizes the land near the coast, light clearing in and about the Okanagan and Kettle River Districts, and medium clearing in the Kootenays. The cost of clearing an acre of land ready for the plough ranges from 50 dollars to 500 dollars, according to the district. In travelling about British Columbia I was struck by the fact that in most cases ten acres (a one man’s orchard) was all the land a man had. His future firewood was not considered. During the first years, tons of wood in timbered districts were burned to get at the soil, and I feel sure that a few years hence the complaint of the lack of cheap fuel will be great. The man is wise who in starting on timbered lands saves all the wood he can for fuel, and I would go still further and say that he should, if possible, acquire cheap adjoining land unsuited for fruit from which he can get his future fuel. I would also advise him to go to the lesser known parts to start his orchard, for if good land is chosen, with means of transport for fruit, there is no fear but that in due time neighbours will come. I have in mind parts of the West Kootenay District where good land may be bought at a reasonable figure, and a steep piece of hill-side bought to yield fuel. In the process of clearing timbered lands and burning large quantities of wood to get at the soil an excess of potash is formed, and clover crops grown and ploughed in are a necessity to bring back the nitrogen. In many cases the dense timber has excluded the sun for generations, and time which is given for the sun to sweeten the soil after clearing on these lands is time not wasted, but well spent. Often the neglect of such things as clover and sunshine results in disappointment in the early stages of an orchard. Again, the stumps of trees are too often left in the ground in the race to get a piece of land planted, and these are always in the way, difficult to pull out and impossible to blow out after an orchard has been planted, B2 4 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. except by sacrificing the fruit trees, and if left in the ground they interfere with the yearly cultivation of the ranche. So far the idea—one might almost say the rule—has been to plant many varieties and a few of each. But, looking at the business-side of it, ship- ments must, if they are to be made successful, be made by carloads, not by boxes, and in choosing varieties plant, say, three or four varieties for selling on ten acres, so that their picking will not come at the same time, and so that you may sell quantities of the same fruit off your own orchard rather than be compelled to hunt for somebody with the same variety (whose apples may be better or worse than your own) in order to make up a consignment. In the choice of varieties of course the best dessert is the highest priced apple, but some of the best varieties are shy bearers, or poor pollen- — producers, and remember in making your selection that most of the Government’s excellent pamphlets are taken from experiments carried out in other provinces, or in the States, and in neither case is the climate the same nor are the soil and conditions similar to those which are found in British Columbia. For in a large province like this the different districts themselves vary enormously in these respects. Peaches, strawberries, apples, and a variety of other fruits are grown in British Columbia, but it depends entirely on transport, markets, and the locality as to which will be the best business proposition. In very few cases can one rely on the nearest town for the sale of all the fruit grown avound it; but the Prairie on the east and Australia on the west are places where fruit is wanted and where it will sell. Hach year more settlers come out to Canada, and a large proportion of these go to places where fruit cannot be grown, increasing the numbers of miners, farmers, &c¢., who have to buy their fruit. At present we read that not half of the fruit consumed is raised in the province, yet some of this fruit, such as oranges and lemons, must be imported, and although there seems every probability that the demand, which is at present good, will continue for fruits which will travel long distances, yet local markets only can be relied upon for the ‘‘soft’’ fruits, and such demands are not large. T would say in conclusion that there are many things which if run in conjunction with an orchard will help to tide over the five years of wait- ing until the bearing stage is reached, without growing such fruits as strawberries. Honey, eggs, and milk are all profitable, and, given energy and good business instincts, British Columbia has openings for many. Perhaps the most difficult decision which you are asked to make is in the selection of the land on which to make not only an orchard but with it your home. FRENCH GARDENING, 5) FRENCH GARDENING. By Mr. C, D. Mackay, F.R.H.S. [Lecture delivered January 5, 1909.| For many years I have advocated the growing of early salads in the way used by the French gardener or maraicher, but until recently only one or two such gardens had been started. Within the past year intensive cultivation has excited an enormous amount of interest among the leisured classes and among those who have gardens and gardeners of their own, and to these I more particularly wish to speak. Now that they have been awakened to the simplicity of growing early salads in their own gardens, they wonder why they have not attempted to supply themselves instead of being dependent on the foreigner as in the past. They had seen the gardens round Paris and marvelled at them, but they were under the impression that in our climate such methods as are there employed were doomed to failure, whereas there is virtually but very little difference, in fact only about two degrees in temperature, between Paris and London, and although they do not have the black fogs we do, they certainly haye damp white ones. The cry in the past has always been that our climate is not the slightest good for growing vegetables in the manner adopted in France, and that in France they have no frost, fog or snow, and no other difficulty to contend with, in rearing the plants. Of course this is not the case. The French gardeners who have had experience in this country say that the climate here is good, and that the lettuces did not ‘‘ fog off” as they do in Paris. | Perhaps gardeners in this country have also been to blame, in that they have religiously adhered to their old-fashioned ideas. They knew only by hearsay of the wonderful way in which the French grew their early salads, and although their employers may have seen the methods employed and the results obtained, yet the gardeners had no opportunity, and possibly no desire, to see for themselves, and they foolishly con- demned a system which they did not understand. One essential must always be borne in mind: when gardeners attempt the system they must have the right varieties of seeds to grow, and it must not be thought that our usual varieties of lettuces, carrots, &c., are just as good as the proper varieties. Ours really is a most favoured country, especially in the South and West, for this kind of intensive cultivation, and there should be no necessity for the huge quantities of lettuces, carrots, radishes, &c., to come from any foreign country as they do now. Actually lettuces are now (January) coming in from Paris and are realizing good prices, and why ? Simply because our growers are so lethargic and non-progressive that they will not believe it possible to work the system successfully here ; neither is it, unless they adopt the same methods as the French people ; 6 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. these methods I will endeavour to explain a little later on. One thing, however, I am grieved about, viz., that a few people, who would practically not make a success of anything, have been lured by the golden prospects held out to them in certain sections of the Press, into embarking in an attempt to secure, from an outlay of £100 to £200, the comparatively enormous income of £400 or £500ayear. This, too, simply because they may have read a newspaper article, or my book on French gardening. For instance, I have been in communication with engineers, clergymen, and many other professional men who have had long years of training for their particular professions and who cannot make a successful living, ° but they think that with possibly £200, the amount mentioned in my book as possible, they are immediately going to make a good living without having the slightest idea of the method of work. I asked an eminent surgeon the other day if he thought that by reading a book upon surgery I should be able to operate successfully on any one. He said he would not care about my doing so on him at any rate, and I retorted that neither could a man by simply reading a book become a skilled gardener. IT am also sorry to see that the public are being asked to subscribe to large ventures of this description. Personally I do not think that French gardening on a large scale is to be advocated. The methods are suited to small gardens of one to two acres only, and such gardens require the unremitting and assiduous care of the proprietor himself. The name which has been coined for the system, “intensive,” is a very apt one, for it is not, and can never be, an extensive one. About fifteen years ago it occurred to me that there was no reason why we could not grow lettuces here, just as they did in France, and in conversation with an eminent French seedsman I learnt that it was the variety of lettuce which enabled the French to achieve such seeming wonders. I promptly got some of the seed, giving it to some of my Hinglish friends, but it was a failure. Going somewhat further into the subject I found that the seed was not everything, but that the way the plants were cultivated was also an important factor, and the cultivation is somewhat as follows. ‘The French maraicher, and now the English gardener, begins to collect his manure from July onwards, storing it in great heaps. This he keeps until he requires it in December and during that month he collects an equal quantity of fresh manure. This is then mixed in equal quantities and spread nine inches deep on the ground, and on the top of this the frames are placed. About six inches of soil is added to the top of the manure, and on this are sown radishes and carrots in January. Lettuces are planted in the frames at the beginning of January, and are cut towards the end of February. Lettuces are not required in this country very early. The particular cabbage lettuce grown is one that has never been used in this country, except in the few French gardens now existing. It is quite distinct from any lettuce which we are in the habit of growing. If this lettuce is planted in the spring time, it will immediately run to seed, but if sown in October under cloches, the plants soon come up, and after a few days they are pricked out, twenty-five under a cloche, and left until they are wanted to finally replant in the beds in January. FRENCH GARDENING. i Tt is astonishing that there are 2,160,000 cloches used in the immediate neighbourhood of Paris, and that there are also 1,000,000 lights devoted to the same purpose. The vegetable produce from these lights fetches the enormous sum of £500,000. The straw mats which are used for this kind of gardening, or any other if necessary, do not absorb the wet like an ordinary Archangel mat, but allow the water to run off, and they quickly dry and are easily rolled up. Cos lettuce, which is, if anything, more easily grown than the cabbage variety, is a Splendid crop for paying when got into the market before _ our English outdoor ones are ready. They have to be raised at the same time as the cabbage lettuce, and pricked out in cloches, 25 to the cloche, but instead of being put under lights as the cabbage lettuce is, they must be planted out in small beds under cloches. Under each cloche one cos and three cabbage lettuce are planted, and over the whole of the ground carrots, such as have been sown in the frames, are sown. On the outside of the cloches small-sized plants of another variety of cos lettuce, grown especially for the purpose, are planted to be coming on, and as soon as those under the cloches are cut, those outside are ready to have the cloches moved on to them to get a second crop. Of course it would be absurd for everyone to start a French garden, either small or large, but it will be a long time before enough gardens are in working order to supply our wants. I most strongly urge those who wish to go in for French gardening to have a French expert. It is the cheapest in the end, as he can make his wages with extra crops at times when an English gardener would not dream of trying to get them. Iam no advocate of market gardeners rushing to invest large sums of money before they have gained the requisite knowledge, but they can start in a small way, and whatever money they expend will not be lost, as both the cloches and the frames are admirably adapted for other methods of cultivation, and I had this class of men in view when I mentioned an outlay of £200 as being all that was required for starting a French garden. ‘It is a pity that those interested in this or any other particular kind of gardening do not go and see the methods of our French, Dutch and German friends for themselves. None is so perfect that he cannot learn something, and if we go with unprejudiced minds we shall pick up ideas which may lead to the improvement of their own system. Now the Dutch are if anything slower than we are in taking up new ideas, but they have started growing early vegetables and salads round the Hague, and they do it extremely well. In our own country we have an enormous population, and a population who can afford to go to Paris for these delicious early vegetables. It is only necessary to educate people up to the fact that they can obtain them in England, and, moreover, that they can have them fresh either at lunch or dinner cut the same morning, instead of being sweated in boxes coming from France, taking three or four days over the journey, then possibly lying in a shop window for two more days until sold. In advocating the growing of early vegetables in England please do 8 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. not misunderstand me. This is no golden road to riches. In growing these vegetables, hard work year by year is the only means of gaining success. It is true we may “French garden’’ here, but it is also true that it entails very hard work. “Golden soil”’ is very alluring, and the gross profits of a concern run on the lines indicated merits the name, but only the indefatigable toil of a French maraicher devoted to it will make it a success. It may interest you to know how many of these lettuces, &c., are sent every day from February to April to London. The usual consignment every day is four to five thousand crates of lettuces, 500 crates of small early carrots, 100 crates of asparagus, 100 crates of long French turnips, and 50 crates of celeriac. Do not these figures give you some idea of the importance of this method of gardening ? People say that this gardening will soon be overdone. I do not think this will be the case. At the present time the prices of lettuces and carrots in the very early spring are prohibitive to all but those who are fairly well off; but if by production one can cheapen them so that they come within the reach of everybody, the present quantity of 5,000 crates of lettuces a day will speedily jump to 20,000. These particular lettuces are sold by the French gardener to a middle- man at 6d. a dozen all through the season, the growers themselves do not ship anything to England. If the French gardener gets 6d. a dozen he is quite happy, and it pays him well, and I have seen no French gardens which do not look as prosperous as they can possibly can be. As you all know, here there will be no difficulty in getting 1s. to 1s. 6d. a dozen, even if they are what you consider to be low in price. Many will remember the time when tomatos were grown only to a very small extent, when they fetched a high price. When the Canary Islands and other early places began to send in their tomatos, it was thought that it would kill the English trade altogether, but has it? I should say that at the present day there are two to three cwt. of tomatos grown where one pound used to be grown years ago. They are one of the most paying crops, no matter whether grown inside or out of doors. When Guernsey began growing tomatos, did they suppose for one moment that thousands of baskets would be sent away every week ? Why should not this success be reflected in a partial way for these lettuces and other produce ? I advocate growing strawberries under glass, not in green houses in the ordinary way, but in frames such as are used for this particular style of gardening. As you know, strawberries when they first come in from the open eround are sold for anything from 9d. to 1s. 6d. per lb., and if they had been brought on earlier by being covered with lights they would have sold for double that price, and at this price they are a very paying crop indeed. EFFECTS OF GROWTH AS SEEN IN MOVEMENTS OF PLANT-ORGANS, 9 THE EFFECTS OF GROWTH AS SEEN IN CERTAIN MOVEMENTS OF PLANT-ORGANS. By Rev. Proressor G. Henstow, M.A., V.M.H., &e. [Lecture delivered April 6, 1909.] . IntrRoDuctTion.—One of the most prominent effects of growth is the result- ing movements of plant-organs. Though the most obvious characteristic of plants in general is that they are fixtures in the soil; yet, probably all the higher plants, at least, have their growing parts more or less in motion for a time. In some cases of microscopic aquatic organisms, the whole being is in motion in the water, as, e.g., diatoms, Oscillatorias, and the zoospores of Alge. It is not known for certain how the first two * effect their movements, but they are in some way dependent on the properties of protoplasm ; the third are provided with protoplasmic cilia, and these are obviously the instruments of motion. There are also numerous movements of protoplasm within cells, especially when the process of cell-division takes place. The well known “streaming ”’ and “ rotation ’’’ are continually going on and well seen in Chara; but these will not concern us now. Other movements of organs are also the result of forces within the cells, and not the direct consequence of external agencies ; some of these will be referred to; but it is especially the movements resulting from stimuli of the surrounding physical conditions of life which I propose to deal with. As soon as plants begin to.grow, their organs are subjected to, and respond to, various external stimuli; and the problem is to detect which is, or are—as there may be more than one—acting upon any organ at any one time. The chief influences are (1) light and (2) shade; 1.¢., really, varying deerees of light till perfect darkness may occur. (3) Varying degrees of heat and cold. (4) Moisture in the air or soil. (5) Gravitation, always acting in a direction perpendicular to the earth’s surface. (6) Contact with a resisting surface. (7) To the preceding may be added the internal influence of céllular growth, which produces external movements of growing shoots. Organs may be developed under these influences without movement ; but if their positions be altered, they will move or turn towards the source of the influence. Both the tendency to respond to any of these influences may become a fixed and hereditary character, and take place when the original exciting influence is absent; and the structwre itself caused by response may be, and usually is, hereditary as well; so that it may be formed completely or partially previous to the commencement of the action of the stimulus which had originally given rise to it. * See Cryptogamic Botany, by Bennett and Murray, pp. 422 and 442. 10 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. The terms I propose using to express the “ turning ”’ towards the stimu- lus are as a (1) Phototropism (to diffused lght), and Heliotropism (to the sun); (2) Skototropism (to shade or darkness) ; (8) Thermotropism (to heat) ; (4) Hydrotropism (to moisture) ; (5) Helkotropism (to attraction of Gravitation) ; (6) Haptotropism (to touch) ; (7) Orthotropism (becom- ing erect or pendulous) ; (8) Circumnutation (bowing around). I avoid the usual term Geotropism, used for the influence of Gravita- tion, because a “turning earthwards’’ may be due to shade as well; while Apogeotropism, I would regard as a synonym for one application of Orthotropism ; for organs can place themselves in a vertical position from more than one cause. — PHOTOTROPISM, HELIOTROPISM AND SKOTOTROPISM, OR THE HFFEOTS oF LIGHT AND SHADE. In flowering plants, as soon as a seed begins to germinate, the root- end (radicle) and shoot-end (plumule) of the embryo first begin to grow in opposite directions, under the influence of external stimuli. The first question is, Why do they grow orthotropically, 2.e. in a vertically straight line, and why does the former bend downwards and the latter up- wards, if the growing seedling be placed horizontally? As gravitation is a constant force acting vertically downwards, we might naturally infer that this was the cause acting on the root, and so the “ turning downwards,”’ under the influence of gravitation was called “Geotropism’’ and the turning upwards of the shoot was named “ Apogeotropism.’’ These words are descriptive only, not explanatory. If we turn to the simplest or unicellular organisms, such as the aoeneal spores of Cryptogams, which have no polarity or any distinction of parts, we find that the two most important stimuli are hght and shade. Thus the first cell-division, as in the spores of Fucus, Hquisetum* and Ascophyllum, t is approximately at right angles to the incident light, the daughter-cell facing tbe less illuminated half develops into the root, while the other becomes the shoot-end. Sachs describes and figures the shoot and gemmule of Marchantia, and the structures are reversed when the usual dorsi-ventral arrangement has been made to be ventri-dorsal. { Similar effects are produced on the prothallia of ferns ; so that the position of the sexual arrangements are always on the shaded side. If the prothallium be grown immersed in water it curves itself so as to be at right angles to the light and then produces those organs on the shady side. Chlorophyll granules illustrate both phototropism and skototropism very well; for in diffused light they spread themselves over the super- ficial cell in such simple plants as duckweed ; such would be phototropism ; but if the direct light of the sun be very intense they place themselves over the vertical walls to avoid it. This movement is therefore skototropism or apheliotropism, whichever term be preferred. In the case of germinating embryos of plants which do not grow on the ground, as the mistletoe and epiphytes, the roots adhere to the bark of * See Origin of Plant Structures, p. 197, note. t Res. Gen. de Bot., I., p. 58, fig. 5. t Sachs’ Phys. of Plants, p. 524-6. EFFECTS OF GROWTH AS SEEN IN MOVEMENTS OF PLANT-ORGANS. 11 trees and do not grow downwards, but turn towards the darker side. In the mistletoe the hypocotyledonary axis terminates in a pestle-like expansion in adaptation to the bough to which the seed adheres by mucilage. This peculiar organ is prepared by. heredity in advance, in readiness for adhesion, just like the pads of Ampelopsis Veitchit. In epiphytes, as orchids and aroids, some roots cling to the stems horizontally, while others descend freely and vertically to the ground; so that while shade determines the former to grow towards, and haptotropism,* to cling to the stem as they elongate, gravitation affects the latter. The climbing roots of ivy also emerge from the less illuminated side of the stem. ‘This latter, too, is acted upon by shade, for when the stem reaches the top of a wall the terminal shoot bends downwards in order to erow flat upon it. As it is quite immaterial whether the ivy be, growing on the north or south side of the wall, the movement can only be due to a preference for less illumination. Of course this is now a hereditary adaptation to the production of climbing roots. Similarly do the shoots of Ampelopsis turn to the shady side, as they require their adhesive pads to adhere to the wall. Ordinary leaves place themselves at right angles to incident light. This might be called diaphototropism.r The consequence is that they are dorsi-ventral in structure; but some have acquired the now hereditary habit of reversing the sides, as Alstroemeria. The internal structure is correspondingly reversed. It is produced by a twisting of the short petiole, possibly to acquire strength, just as the ovary of Orchis, which has no central placenta, acts as a strengthening pillar. If a naturally growing blade be partially fixed in a reversed position when growing it makes a most determined effort to right itself. Now the orthotropic growth of ordinary stems and the axial roots of germinating seedlings, was presumedly and primarily (like spores) due to phototropism and skototropism respectively. This is well seen in growing seeds, as of mustard, suspended in water, and covered above by a screen, but exposed to bright illumination from below only. In this case the hypocotyls all turn downwards. HEREDITARY INFLUENCES.—DBesides the influence of shade, as the root grows downwards gravitation acts upon it and its effects have become fixed and hereditary. Similarly growth in opposition to it, primarily due to phototropism, has become fixed ; so that shoots fresh cut and laid in total darkness will turn up their tips. That one of the elements of geotropism, 2.e. ‘ turning earthwards ”’ is skototropism is seen in young roots, say of mustard when grown in water, which offers no resistance. If the glass vessel be surrounded with black paper, one strip only being left uncovered for the entrance of light, all the roots bend to the opposite side. Roots of cabbage grow downwards though illuminated only from below. Mr. W. G. Smith described, some years ago, how the stolons of Saxifraga sarmentosa in a pot by a window grew inwards, but as they produced new rosettes, they turned towards the window, their stolons growing inwards till they produced secondary rosettes and so on. He * A term proposed by Prof. Leo Errera, for action of tendrils, ete. Dia-, in the sense of ‘‘ across.” 1b JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. notes that other stolons on the ground, as strawberry runners, have a strong tendency to “congregate in more than usually shaded places.”* Now it must be emphasized that many habits of plants due to growth originally caused by responses to external stimuli may become so per- manently fixed in the life of the species that they occur when the original stimulus is not present. This permanency of acquired habits is thus well described by Professor Vines. In speaking of the periodicity in the circulation of water in plants, he says: “It has doubtless been induced in plants by the daily variations of external conditions, perhaps more especially of illumination, which are involved in the alternation of day and night; but it has become so much a part of the nature of plants, that it is exhibited, even when the conditions which originally induced it are not present, and it is transmitted from generation to generation.’’+ Darwin corroborates such tendencies to become hereditary. There is reason to think that an acquisition of any special habit may become fixed and hereditary. Perhaps one of the most conspicuous is the orthotropism of the terminal part of a stem in total darkness when it has been placed horizontal, already referred to. It is customary to attribute this orthotropism to gravitation ; but we must remember that erect stems grow in direct opposition to it; and, to do this, the stem develops varying amounts of mechanical tissues, always somewhat in excess, to resist the ever existing downward “pull”’ of gravitation, and other strains due to wind, &e. A remarkable instance of change of direction is seen when the tap- root or the terminal shoot of the stem is removed. In the former case, the secondary previously horizontal roots grow downwards, and the boughs near the top grow upwards. These changes must be partially at least attributable to some sudden impulse due to the checks given to the flow of sap in both cases, coupled with gravitation and light. A permanent result of the former is seen in all Monocotyledons and aquatic Dicotyledons, as in neither is the tap-root preserved, but numerous adventitious roots arise from the stem and grow downwards, supporting it as well as absorbing nourishment. Analogous instances may be seen in the two varieties of trees called “fastigiate’’ and “ weeping.’’ In the former ali the branches grow orthotropically, and in the latterin a pendulous manner. How these habits arise is not known. It appears they may (as in Irish yew), or more probably may not, be hereditary, as in the ash. Seedlings sometimes show at first a slight tendency “to weep,” but subsequently lose it. Sachs gives an excellent illustration to show these inherited tendencies to orthotropism. A Yucca gloriosa growing in a pot, with its vertical rhizome, is inverted. In this condition buds on the rhizome, as well as roots are developed from it, the former grow vertically upwards and the latter downwards, though both are, of course, in total darkness, as they are buried in the soil. $ * Gardeners’ Chronicle. t+ Physiology of Plants, p. 96. t Movements of Plants, pp. 407, 491. § Sachs’ Physiology of Plants, p. 529, fig. 344. EFFECTS OF GROWTH AS SEEN IN MOVEMENTS OF PLANT-ORGANS, 18 In the preceding few cases, the organs grow in accordance with the external stimuli; but if the relative positions of plants with respect to light, gravitation, &c., be altered, then the organ moves or bends out of its original direction to try to put itself in harmony with it. These external stimuli, therefore, first, induce growth, and then, when the direction is changed, the plant-organs respond and move themselves so as to be in adaptation withit. Thus, if cabbage or other seed be grown in a pot, upon which the light falls from one side, the seedlings, as they come up, at once grow towards it. If the pot be reversed in position, the hypocotyls begin to bend, about one-third of their length from the cotyledons, the curvature extending downwards till the middle of the concave side is about half-way. There is no circumnutation, but a bending solely in a vertical plane. This phototropism may be repeated again and again if the pot be repeatedly turned half-round. How are we to account for the fixed and hereditary habit of ivy and Ampelopsis turning their shoots in the direction of the less illuminated side ? Comparing the climbing position of the stem with the upper free- growing flowering branches of ivy, the latter have just the reverse habit, for they grow outwards, away from the trunk and branches of the tree to which the lower part of the stem clings. Similarlyin the Virginia creeper, the tendrils were originally adapted to grasping twigs and climbing by that means, as do vines, to which the Ampelopsis is closely allied. There seems to be but one answer, viz., it is an acquired and now hereditary habit. A species of Trichosanthes of the cucumber family, cultivated in a frame, accidentally found its tendrils pressing against the brick wall. Contrary to its normal habit, it at once began to make adhesive pads ; and so we may imagine that the ancestor of the Virginia creeper first acquired this habit in a similar way, the tendrils being now fixed to the wall by adhesive pads; so that its illumination is one-sided. This unequal illumination we must assume caused a response to arise which now induces the shoots to grow or turn towards the darker side. Of course, the origin of all epiphytal plants which cling to the boughs or trunks of trees by means of aérial roots will receive the same interpreta- tion. ‘Thus a tropical epiphytal orchid begins by the seeds being blown up to and resting on the boughs. It could not long remain there wnless its roots could cling to the bough. We rust assume, therefore, that they turned towards the bough, as the radicle of the mistletoe does, that is the less illuminated side, and adhered by clasping and cementing epidermal cells. HypRoTRoPiIsSm and HELKOTROPISM.* Both moisture and gravitation play a great part in determining the direction of root growth. The latter is a feeble force and easily counter- acted by the former, as Sachs has so well shown +; but when roots are permeating a uniformly moist soil, as they arise endogenously at right * T suggest this word, as Geotropism may be partly due to darkness and moisture besides gravitation. The Greek verb helko, to ‘“ attract,’’? is used of the magnet, as well as of the ‘‘ drawing ” down of a balance by weight, 7.e., gravitation. t Phys., p. 715, fig. 404. 14 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. angles to the parent root, they simply continue to elongate more or less in the same direction. If, however, they be in a comparatively drier place and a moister one be at some distance, they will grow in the direction of the latter quite irrespective of gravitation. So that Hydro- tropism easily overcomes Helkotropism. A good illustration of what may be most probably due to gravitation alone is seen in the descending aérial roots of the Indian fig or banyan ; inasmuch as the dense shade would be above and light below ; so that as the roots pass through the air this would be throughout equally dry or moist as the case may be, leaving gravitation alone to exert its influence. THERMOTROPISM. Another stimulus of attraction causing movements, is heat. When one side of a plant receives a higher degree of temperature than the other, stems and leaves will often turn to the warmer side. Kerner observes that in the high Alps, the air being rarefied, the exposed ground receives great heat from the sun; but the temperature of the air above it may be lower; so that many plants creep along the ground, such as species of willow, “ Juniperus pyramidata var. humilis, called the ‘ creep- ing Sabina.’ J. nana or alpina, ve. a dwarf form of J. communis, sends out from the collar of the root long branches tang on the ground, as is generally the case with Alpine plants.”’ * Kerner gives the excess of the mean temperature of the soil over that of the air of different altitudes on the Central Tyrolese Alps as follows : at 1,000 m., 1°5°C. ; at 1,300 m., 1°7°C.; at 1,600 m., 2°4°C. ; at 1,900 m., 3°0°C. ; and at 2,200 m., 3°6°C. In warmer climates similar phenomena are to be seen. I frequently noticed in Malta that very many plants are prostrate when growing by road sides, where the limestone rock is often exposed and gets heated. The Maltese ‘clover,’ Hedysarum coronaria, grows to a height of 3 feet in the fields, but stray plants are perfectly prostrate by the roads. The same thing occurs with both Malva sylvestris and M. parviflora. Similarly with leaves, a small species of dandelion often grows between the loose stones of walls in Malta. When extracted, the leaves, which were flat against the hot vertical wall, curled back against the root. and refused to be straightened out when required to be dried. In early spring in England, bluebells may be seen having their first formed leaves lying flat on the ground, and daisies and plantains always have them so in a close-cut lawn. The following observations on temperatures will perhaps show how thermotropism may account for the prostrate position independently or conjointly with light, a feature of common occurrence in this country. The temperature at the surface of the damp soil by the side of a blue- bell growing in the shade of trees, at 9.45 a.m., April 15, 1891, a sunless morning, was 47° F. The temperature of the air three inches above the ground at the same time and place was 44°5°. At 4 p.m. of the same day, on the surface of the soil the temperature was 60°; while that of the air * See Origin of Plant Structures, pp. 101, 102. EFFECTS OF GROWTH AS SEEN IN MOVEMENTS OF PLANT-ORGANS, 15 was 52°. Similiar differences, only varying slightly, occurred on a mown lawn. These observations appear to suggest the cause of the long creeping stems in sand by the sea as of Carex arenaria, Agropyrum (Triticum) junceum, &c., in that the hot, upper layer of the sand may be the stimulus to develop shoots which then grow horizontally below the surface; this suggestion is supported by the fact (recorded by Babington) that Hordeum murinunm var. arenaria, Bab., has ‘‘the lower part of the stem buried, lengthened and rooting, thus appearing to creep in the sand of the sea- shore.”’ Experiments have shown that the shoots of cress seedlings curved away from the source of heat whereas maize seedlings curved towards it. The roots of hyacinths are thermotropic, but the leaves apothermo- tropic (Vines). I found seedlings of wild cabbage were indifferent to heat, when the pot containing them was in total darkness, the temperature by the side next a fire being 100° F., and the opposite side, 80°. The pot was 3 inches in diameter. HAPTOTROPISM AND APHAPTOTROPISM. So many cases of organs bending after being touched are described by Darwin in his works on The Movements of Plants and Insectworous Plants, - &c., that the reader is referred to them. With regard to root-tips, ‘ Sachs discovered that the radicle a little above the apex is sensitive and bends like a tendril towards the touching object. But, when one side of the apex is pressed by any object, the growing part bends away from the object. . . . We are therefore led to suspect that the apex was sensitive to contact . . . Some few stems bend towards a touching object, but no case, we believe, is known of an organ bending away from one.”’* The advantage of this power to a root penetrating the soil is obvious. ORTHOTROPISM. Besides phototropism, another kind of orthotropic motion is produced by growth in the development of leaf-buds. If the opening bud of lime or beech be observed in spring, the young leaves, as they appear, curve downwards, and as they gradually enlarge and become full-grown, rise up again and assume the horizontal position. In the walnut the petiole of the pinnate leaf curves strongly downwards, and only rises when the leaflets are fully developed. In the ash the petiole curls upwards. In every case they are in a vertical line, hence I call it orthotropism.t The “ object’ of these movements is to place the delicate immature blades in an erect or vertical position so as to avoid the chill produced by radiation, which is always greater from a horizontal surface. Leaves perform very similar movements in the tropics, but in this case it is to protect them from desiccation under the powerful heat of the sun. The movement, therefore, is apheliotropism. * Movements of Plants, pp. 131, 132. t “ Vernation and the Methods of Development of Foliage, as Protective against Radiation.’’—Jouwr. Lin. Soc., vol. xxi. p. 624. 16 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. In intensely cold winters the leaves of evergreens, such as holly, may be seen to hang vertically downwards as long as the cold lasts. - An analogous orthotropism is seen in the sleep or hypnotic condition of plants fully described by Darwin, in his Movements of Plants. CIRCUMNUTATION. As soon as the root and stem have grown long enough, having been vertical at first, they both begin to move approximately in circles or ellipses. This is presumably due to the apical growth of the stem not being strictly simultaneous at all points of the circumference. I the tip of the stem of some cryptogams—say, Hqwisetum *—which is simpler than that of an Angiosperm, be examined, it will be found to possess a conspicuous terminal cell. From this, new cells are cut off in a spiral order, the centre of each cell being at 120° from the preceding, as measured on radii from the centre of the apical cell. Though it has not been clearly demonstrated that the apices of Angiospermous stems start with a single cell, as this apex is so soon composed of a mass of merismatic tissue, still, judging by the “ bowing around,” or “circumnutation’’ as it is called, in a continuously spiral manner (allowing for irregularities), one is inclined to assume that a batch of cells at one point precedes in its formation that of another, about 120° from the former, just as is the case with single cells in the apex of the stem of Hquisetum or horse-tail. Darwin has given us many diagrams of traces, both of roots and stems, circumnutating, so the reader can consult them in his work on The Movements of Plants. Circumnutation of a stem, therefore, may be assumed to result from the process of growth in a definite manner. Perhaps the most con- Spicuous case is seen in the movements of climbing or twining stems. Darwin attributed this to the elongated shoot bending or nodding around, in search, as it were, of a support. As soon as the stem touches another all motion is arrested below the point of contact, while the upper part continues to nutate, and so it winds itself round the support. Sachs calls attention to an omission, that the apex in consequence of the continued elongation of the stem, really moves in a spiral or corkscrew-like manner. This may perhaps facilitate the twining process. Tendrils also circumnutate until the tip has coiled round some object (by haptotropism) ; having acquired a sensitiveness to touch, the previously straight tendril then coils itself into spirals, as many times in one direction as in the opposite. This is effected by means of crank-lke straight lengths rotating. I have described this in detail elsewhere.® - The circumnutation of more or less completely formed organs, such as leaves and tendrils, seems to require some other interpretation than apical growth ; and at present there does not appear to be any satisfactory explanation of this phenomenon. * See Fig. 111 in Sach’s Text Book of Botany, p. 143. + Darwin, however, appears to recognize this fact, for he says: ‘The belief that twiners have a natural tendency to grow spirally, probably arose from their assuming a spiral form when wound round a support, and from the extremity, even whilst remaining free, sometimes assuming this form.’’— Climbing Plaivts, p. 17. { Jour. R. Hori. Soc., vol. xxxiv. p. 417. EFFECTS OF GROWTH AS SEEN IN MOVEMENTS OF PLANT-ORGANS. 17 Of course there are many more cases of special character, but the reader is referred to Darwin’s two books, Climbing Plants and the Move- ments of Plants, which supply an abundance of information. In conclusion, I would summarize what appear to be important pro- cedures in Nature. 1. The external stimulus is the cause (by means of the responsive power of the organism) of a definite or special structwre in adaptation to it ; e.g. light and shade causing polarity. 2. If the direction of the stimulus be changed, the organ may move so as to put itself in adjustment with it; e.g. Phototropism, Hydro- tropism, &c¢. 3. The tendency only, to produce the structure may be hereditary ; e.g. in the formation of adhesive pads in Ampelopsis hederacea. 4, The structure itself may be hereditary and be more or less completely formed before the influence can act; e.g. in the formation of adhesive pads in A. Veitchw. Such is the inheritance of acquired characters. 5. The direction of the growth of the organ can be hereditary apart from the presence of the original stimulus which caused it; eg. the erection of shoots laid horizontally (originally due to light) in total darkness. VOL. XXXV. C 18 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY, THE INTRODUCTION On THE TULLE. AND tet TULIPOMANTIA. By Mr. W. S. Murray, F.R.H.S. [Read March 9, 1909.] DurinG the preparation of this paper on the introduction of the Garden Tulip into Hurope and the subsequent craze or gamble in the seventeenth century, I have had the privilege of consulting the magnificent library belonging to Mr. Krelage, and at the outset I take the opportunity of thanking him for his kindness and courtesy in allowing me free access to it. The first mention of the introduction of the Garden Tulip into England is made by Richard Hakluyt, who, in 1582, in his “ Remem- brances of Things to be Endeavoured at Constantinople,” says: “‘ And now within these four years there have been brought into England from Vienna in Austria divers kinds of flowers called Tulipas, and these and others procured thither a little before from Constantinople by an excellent man called M. Carolus Clusius.”’ Hakluyt was, however, wrong in attributing the honour of introducing the Tulip from the Levant to Clusius. When Augerius Ghislenius Busbequius, the Ambassador of the Emperor Ferdinand I. to the Sultan, was travelling to Constantinople in the year 1554, he saw this flower for the first time in a garden between Adrianople and Constantinople. The most remarkable passage in his letters on his journey reads as follows: ‘As we passed, we saw everywhere abundance of flowers, such as the Narcissus, Hyacinths, and those called by the Turks Tulipan, not without great astonishment on account of the time of the year, as it was then the middle of winter, a season unfriendly to flowers. Greece abounds with Narcissus and Hyacinths, which have a remarkably fragrant smell ; it is indeed so strong as to hurt those that are not accustomed to it. The Tulipan, however, have little or no smell, but are admired for their beauty and variety of colour. The Turks pay great attention to the cultivation of flowers, nor do they hesitate, though by no means extravagant, to expend several aspers for one that is beautiful. I received several presents of these flowers, which cost me not a little.” * The assertion that the Turks call the flower Tulipan is founded upon a misunderstanding, as the only Turkish name for Tulip is “ Lale.” The interpreter to Busbequius may have described the flower as being similar to the Turkish headgear, the fez, which is the shape of a cup. ‘‘Dubbend ”’ is a Persian word for Nettle-Cloth, such as the Turks use as a fez, and from which Europeans derive the word turban. Some few years later, in 1559, Conrad Gesner saw the first Garden Tulips that were grown outside Turkey growing in a garden at Ausburg, * Busbequii Hp. Basiliae, 1740, p. 36. THE INTRODUCTION OF THE TULIP, AND THE TULIPOMANIA, 19 and described them in 1561.* He says: “In this year of our Lord 1559, at the beginning of April, in the garden of the ingenious and learned Councillor John Henry Herwart, I saw there a plant which had sprung from seed which had been procured from Byzantia, or as some say from Cappadocia. It was growing with one large reddish flower, like a red lily, having eight petals of which four are outside, and just as many within, with a pleasant smell, soothing and delicate, which soon leaves it.”’ Levier points out that, according to the description, the smell, and its early blooming, it is known as a spring Tulip, which to-day is described as Tulipa suaveolens, and not as Tulipa Gesneriana, and it may be assumed that these Tulips grown at Ausburg were grown from seed brought home, or sent home, by Busbequius. Clusius in his works does not refer to the Ausburg Tulips, for in comparing the different dates the earliest is 1593, when Clusius came to Vienna, and there met Busbequius, from whom he obtained Tulip seeds, as he mentioned in his “ History of Rare Plants,’ + and as he makes no earlier reference we may take it that these seeds yielded the first Tulips that Clusius owned. Later, Clusius tells us he made experiments as to the comestibility of the bulbs, and in the year 1592 he instructed the apothecary, J. Muler, of Frankfort, to preserve some in sugar, as was done with the bulbs of the Orchids, and he found them far superior in taste and sweetness to the latter. In 1593 Clusius was appointed Professor of Botany at Leiden, but the Tulip found its way into Holland before Clusius and probably quite independently of him. In the “ His- torisch Verhaal,’’ of April 1625, Vol. ix. 9th vers’, Nicolas Wassenaer writes: “The first Tulip seen in Amsterdam was in the garden of the apothecary Walich Zieuwertz, to the great astonishment of all the florists ; but they increased considerably after the celebrated botanist Dr. Clusius came to Leiden, who, besides Tulips, brought with him many other rare plants, such as the Hyacinth of Peru, which was sold for 40 florins, also the first Crown Imperial; and that Dr. Clusius now charged such an extortionate price for his Tulips, so much indeed that no one could procure them not even for money. Plans were made by which the best and most of his plants were stolen by night, whereupon he lost courage and the desire to continue their cultivation ; but those who had stolen the Tulips wasted no time in increasing them by sowing the seeds, and by this means the seventeen provinces were well stocked.” As early as 1590 Joh. Hogeland grew the Tulip in Leiden,t and he possibly procured them from one George Rye, a merchant of Mechlin, who made a study of plants and who cultivated Tulips that he had received from an Hastern merchant at Antwerp.$ Clusius divided his Tulips into three classes in accordance with their time of flowering—Praecoces, the early flowering, Serotinae, the late, and Dubiae, those flowering between the two. He does not lose sight of the fact that such a division could not be of importance, inasmuch as he says explicitly (lc. p. 147) that he has grown from the same seed Tulip Praecox and some single plants of the other two species. Parkinson, however, was stricter in his mode of division, and says in his “ Paradisus,’’ * De Hortis Germaniae, éc., p. 213. t p. 142. ft Clusius, l.c. 147. § Clusius, l.c. 150. co 2 20 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. 1629, ‘ The chief division of Tulipas is into two sorts—Praecoces, early flowering Tulipas, and Serotinae, late flowering Tulipas. For that sort which is called Mediae or Dubiae do near participate with the Serotinae”’ ; further, he denies the possibility of producing a Praecox flower from the seed of a Media Tulip, although, as he says, “I know Clusius, an in- dustrious, learned and painful searcher and publisher of these rarities, saith otherwise.’’ Miller in his ‘‘ Gardener’s Dictionary,’ 1783, says, “ Tulips are usually divided into three classes, but there is no occasion for making any more distinctions than two, viz. early and late blowers,’ and he enumerates five rules of beauty for the Florist’s Tulip, according, as he says, ‘to the characteristics of the best florists of the age.” 1. It shall have a tall strong stem. 2. The flower shall consist of six leaves, three within and three without; the former ought to be larger than the latter. 3. Their bottom should be proportioned to their top, and their upper part should be rounded off, and not terminate in a point. 4, Their leaves should neither turn inward nor bend outward, but rather stand erect, and the flower should be of a middling size, neither over large nor too small. 5. The stripes should be small and regular, arising quite from the bottom of the flower, for if there are any remains of the former self coloured bottom, the flower is in danger of losing its stripes again. The chives (stamens) should not be yellow, but a brown colour. When a flower has all these properties it is esteemed a good one. Laubach tells us of two Turkish manuscripts procured by Von Diez, and now in the Archives of Berlin. The first of the two books, entitled “The Habit of Flowers,’’ was written by the Sheik Mohammed Lalezari, who flourished in the reign of Sultan Achmed ITI., 1703-1730, and wrote also for the Grand Vizier Ibrahim Pasha, 1718-1730. ‘This appears from the first page of the book, which says: “ This is the booklet which was made by order of the late Ibrahim Pasha.” Lalezari, a name which probably means Tupilanist, tells us that he stood in great esteem by the Sultan, who gave him the pet name of Schukjuf Perweran (Connoisseur of Flowers), and in his treatise deals exhaustively in two chapters with the Tulip. The first of these deals with twenty species and explains their points of beauty, whilst the second chapter contains directions concerning the cultivation of the Tulip bulb and seeds. Refer- ence is made to numbers of Tulips and Narcissi with such names as ‘ Mihir Sulemani’ (Beloved Sulemans), ‘Ferah Efza’ (Gladness increasing), and SO On. The second manuscript bears the title “ Acceptable and Beautiful.” It presents a systematically arranged catalogue of various sorts of one flower, but is not explicit as to the name of that flower, the origin of the seed, and the description of the bloom. Von Diez gives a translation as follows: “ As the colour of the violet, curved as the form of the new Moon, her colour is well apportioned, clean, well proportioned, almond shape, needle like, ornamented with pleasant rays, her inner leaves as a Litite van eeniqghe Tulpaen / Werkocht acnde wveelk-biedende / op den 5.

Record of a Tulip sale by auction held at the ‘“ Nieuw Schutters Doelen,” Alkmaar, February 5, 1637, by order of the Governors of the Orphanage, under whose care were the children of Wouter Bartelmiesz, innkeeper of the ‘‘ Oude Schutters Dollen,” Alkmaay.

The flower described would be termed nowadays a ‘ Bybloemen,’ and, as the author enumerates no fewer than 1,323 varieties, although the full description is given of 74 only, one can form an estimate of the many varieties of the Tulip under cultivation in those days. Von Diez further draws attention to the twenty rules of beauty detailed by Lalezari, which corresponded with those of Hurope with one exception. The perfect Turkish Tulip, according to Lalezari, had pointed petals on the 4 to 6 scale; the Western taste of that time, however, demanded a possible rounded form of petal. It seems that the Tulips originally exported from the Turks all had pointed petals. All the varieties illustrated by Clusius are of this form, and of the illustrations in the works of Parkinson, Langlois and Passeus, but very few are to be found with rounded petals, in striking contrast to the demand made by fashion in the second half of the seventeenth century. Von Diez deduces that these Turkish rules were adhered to at the time of the importation of Tulips into Europe, and have been accepted by Europeans. But his contention is not supported by the writings in the eighteenth century manuscripts of Lalezari, and inasmuch as the Tulip was cultivated in Kurope at the end of the seventeenth century, it is possible that a retrospective action towards the Turks was effected ; in other words, that the Turks copied from the Europeans the ways and means of identifying the points of beauty, and the classification of the plants, but it is extremely unlikely that a Turk should have copied anything from a disbeliever, and moreover Lalezari refers to former connoisseurs of flowers who prohibited the watering of Tulips until the growth was well above the ground, and describing the Narcissus he says some of the old teachers had laid it down that it was necessary to lift the yellow Narcissus every third year. This confirms that he had researched in older Turkish writings of which we do not know, and that he draws his conclusions from old Turkish grounds, and from these he obtained the names, and recognized points of beauty. It is possible that the nomenclature and rules of beauty developed in an analogous way. Certainly before the importation of the Turkish flowers into Kurope they were unknown, and at the time of Busbequius the Tulip was held in high esteem by the Turks. These rules of beauty apply only to the florist’s or Amateur’s Tulips known as ‘ Breeders’ (self colours), ‘Bizarres’ (those with a yellow ground lined or marked with purple and scarlet of different shades), ‘Bybloemens’ (having a white ground lined or marked with violet or purple of different shades), and ‘Roses’ (those marked or striped with rose, scarlet, crimson, or cherry colour on a white ground), and they have been dealt with in two excellent papers which have been published in the Journal of our Society, one by Rev. F. D. Horner,* and one by Mr. A. D. Hall. + Seeds sown from either of these four classes of Tulips nrodase invariably self colours, which after an indefinite period “break’’ or * Vol. xv., 1893. Tt Vol. xxvii., 1902. 22 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. change into the colours of one of the three groups, Bizarre, Bybloemen, or Rose. This character of the Tulip has no floral parallel, and at present no scientific explanation has been offered. Tulips are now seldom grown from seeds, as the process although interesting is tedious, taking usually ten years before definite results are obtained, and we are continually getting new and good varieties from the bulbs themselves, which produce spontaneously blooms of more or less the same character but entirely different, either rectified or self-coloured. Two well known varieties from the early flowering class, single ‘la Reine’ and double ‘Murillo’ illustrate this. From ‘la Reine’ we have a yellow, ‘ Herman Schlegel’ or ‘Primrose Queen’; a pink, ‘Rose La Reine’; a deep rose, ‘Reine des Reines’; a white, ‘White Hawk’; and further from ‘ White Hawk,’ ‘Red Hawk’; ‘Flamingo,’ pink; ‘Ibis,’ deep rose ; and ‘ Callipso,’ cream. From ‘Murillo,’ which is itself a pale pink, has arisen a yellow ‘Tea Rose’ or ‘Primrose Beauty’; ‘Harlequin,’ striped; a pure white, ‘Purity’ or ‘Schoonoord’; ‘Paeony White’; ‘Meister van der Hoef,’ pure yellow; and a dark rose and a mauve, which are as yet unnamed. On our farm last season was noticed in a bed of ‘Tournesol’ a pure yellow of that variety. One of the most remarkable variations arising in the Tulip is a form of atavism which occurs in all kinds of garden Tulips, but especially in Parrot Tulips. Occasionally a specimen will lose its character and revert to a form of Tulip with narrow flowers; these have no commercial value and are at once destroyed, but from a scientific point of view they are of the greatest interest. This Tulip is known in Holland as ‘ Tulipa dief,’ or Thief Tulip (fig. 2), probably because it replaces one of some value; the two forms are a deep rose, and a red with yellow border. These have been planted and are found to be constant. The conspicuous characteristic lies in their pointed petals. The first leaf of the largest offset develops in a curved form, that is, the tip of the leaf is elongated into a runner which drives horizontally into the soil and to which is attached an offset. The character of the bulb itself is entirely changed to that of an angular form, similar to the bulb of an unbloomed Parrot Tulip, but lighter in colour. I think this similarity between the bulb of the Parrot Tulip and that of the ‘Tulipa dief,’ rather than the Parrot Tulip being subject to atavism, explains their frequent appearance among the Parrot Tulips. Parrot . Tulips have either a red or a yellow ground, the latter therefore belonging to the ‘Bizarre’ group. That Parrot Tulips are a sport from the late Amateur Tulips has been proved recently at Haarlem, where a fine late Tulip produced unexpectedly a Parrot Tulip of the same colour.* The late Amateur Tulips more especially ‘Roses’ and ‘ Bybloemen’ were among those most sought for and purchased for such large sums at the height of the Tulipomania. The many anecdotes relating to this remarkable mania are well known, and have been copied and possibly enlarged upon by one writer from another, and need not be mentioned here. How or when the mania commenced we do not know, for to find the time with certainty it is necessary to discern where fair trading ends and speculation commences. Munting, in his “ Beschrijven der Kruyden,”’ places the dates as 1634-16387, but M. Van Damme has written to me * Florileguwm Harlemense, Tab. 53. THE INTRODUCTION OF THE TULIP, AND THE TULIPOMANIA. 28 stating that he has recently discovered in the Archives of Haarlem papers relating to disputes over Tulips as early as 1611, but as I have not yet seen them I cannot say what bearing they have upon this point. Munting says that the mania originated in France, where the nobility, especially in Paris, gave hundreds and sometimes thousands of florins for a single Tulip bloom; the more beautiful the colour, the higher the price paid. But we have already seen that Tulips were greatly prized when Clusius was at Leiden, for those he grew were coveted and stolen.

(The vertical line in the middle of the top row represents 1 inch.) more probable that the demand increased with the number of amateur collectors, who would pay high prices for a fashionable or rare specimen, just as to day large amounts are paid for certain postage stamps; but the period of the actual gamble in the bulbs, which was entered into by weavers, carpenters, carmen, and even servant girls, may not have commenced till 1634. | Wassenaer (1623-1625) commented upon the principal varieties of the year ; the ‘Semper Augustus’ is described as the most valuable and 24 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. beautiful. In 1623 he wrote: “The ‘Semper Augustus’ has been the most prominent variety of the year; the colour is white and red, tinted blue underneath. No Tulip has been held in higher esteem, and one has been sold for thousands of florins, and yet the seller was himself sold (so he said), for when the bulb was lifted he noticed two lumps on it which the year following would become two offsets, and so he was cheated of two thousand florins.’’ He says further: “The offsets that the bulbs give are the interest, while the capital remains intact.’’ He also considered that bulbs were a safe investment, for one might carry one’s capital about in the pocket, and if molested by footpads would not have it stolen as with gold or diamonds. One bulb which cost sixty florins has in a short time paid 20 per cent. by offsets, reckoning them at only 6d. each. Wassenaer tells us that in 1624 the ‘ Augustus’ still kept its former reputation, and that there were only twelve in existence. Averaging large and small they could be bought at 1200 florins each. In 1625, 8000 florins were offered for two of these bulbs, but the owner could not be induced to part with them, for, considering that he was the only one possessing the rare bulbs, no one else could procure them, he put his own value, which was very high, on them. It was not to be wondered at that such an easy and profitable business soon found favour, as all that was necessary was to possess a few Breeder Tulips which could be grown in almost the smallest garden. The erowing of tulips from seed had the fascinating possibility that some tulip of exceptional merit and value might be produced. A proof of this is given by Gaergoedt in an answer to Waermondt’s question, “ How the flowers got so many names.’”’ He says: “If a change in a Tulip is effected one goes to a florist and tells him, and it soon gets talked about. Kyeryone is anxious to see it. If it is a new flower each one gives his Opinion ; one compares it to this, another to that, flower. If it looks like an ‘Admiral’ you call it a ‘ General,’ or any name you fancy, and stand a bottle of wine to your friends that they may remember to talk about it.”’ The whole business was based on confidence, and was quite impossible to control, as one could not see when buying the bulb the flower it Fic. 4.—Ftora’s Foou’s Cap; or, Representations of the wonderful year 1637, when one fool hatched another; the people were rich without property, and wise without understanding. This print, which appears in the second edition of the conversations of Waer- mondt and Gaergoedt, published in 1734, depicts a tent in the shape of a fool’s cap, in which are several florists weighing Tulips with goldsmiths’ scales. Outside hangs a sign, as at an inn, showing two fools fighting, and inscribed ‘‘ In the two Bulb Fools.” In the background is the goddess Flora on an ass being beaten and scolded by disappointed florists. Above the heads of those on the extreme right is a rake or claw, meaning that Flora had raised their hopes of wealth to the highest, but they are now in abject poverty. On the left is one well dressed and smiling. This is one of the few successful speculators, and he is turning a deaf ear to one of his victims. On the extreme left is Satan with a rod and line at the end of which is a fool’s cap; on the line are a great many sale notes of Tulips, and in his right hand is an hour glass, meaning “The time is.up.”’ In the foreground are some florists whose reason has left them, throwing their Tulips on the rubbish heap.

That such fraudulent practices occurred we have ample evidence in “Het t’ Zamenspraeken, between Waermondt en Gaergoedt.” Gaergoedt says, “It is right that last year I bought a bulb or two that are not what I bought them for, but what is that compared to the numbers bought?”’ but Waermondt says that his cousin had spoken to people who had bought pounds (in weight) of bulbs purporting to be of such varieties as ‘Crowns,’ but which were nothing better than early double coloured, and even single colours that one may see in any garden. The “ t’ Zamenspraeken,”’ or three conversations between Waermondt and Gaergoedt, was published first in 1637 at Haarlem by Adrian Roman, and purports to be the conversations of two weavers, and from these conversations we learn the way business was transacted during the craze. Bulbs that sold at so much each, or by the dozen, were now sold by weight of so many azen (fig. 5), a small weight less than a grain, in the same way as gold or diamonds. In growing numbers tradesmen and artificers adopted the calling of cultivators and dealers of Tulips, selling their tools and their business, and borrowing money on their houses. The constantly increasing profits from their speculations were to be ample compensation for everything, and now began in earnest the Tulip mania. At the commencement bulbs were sold at the time of delivery from the end of June, when they were taken out of the ground, to September, when it was time to plant them again; later the business extended over the whole year, delivery in summer being agreed upon. As now the prices varied according to the demand ; speculators contrived to get the Tulip trade into their hands; the bulbs became therefore a secondary con- sideration as bulbs, and became the object of a regular exchange and gamble. Collegiums or clubs were formed and held at the inns, which became Tulip exchanges, and we learn that there were two methods. of conducting business. The one as selling “met de Borden or Schijven,”’ the other ‘in het Ootjen.” ‘The first is described by Gaergoedt, who says to Waermondt: “If you wish I will sell you a ‘ Cargasoentje,’ and because you are a good man and my special friend, you may have it for fifty florins less than I would take from anyone else, and if you do not Fic. 7.—Tue Foow’s WAGonN. The original of this rare print, painted probably by Hendrik Pot, who, according to Burger Musées de la Holland, was from 1633-1639 lieutenant in the Guards at Haarlem, shows us a chaise-like car, in the middle of which a sail is fastened, and this, moved along by the wind, carries Flora, who in her arm holds a horn of plenty in which are Tulip blooms, and in -her left hand three blooms—‘ Semper Augustus,’ ‘General Bol,’ and ‘Admiral van Horn.’ In the body of the car are three florists decked out with Tulip blooms, and who are named “ Good-for-nothing,”’ ‘ Hager Rich,” and “ Tippler.” In the front of the car are two women, one named ‘‘ Save All”? (Miser) and the other ‘‘ Idle Hope,” and from whom the bird Hope has escaped. A crowd runs after the ear, calling out ‘“‘ We will all sail with you,” and in their eagerness discard and trample on their weaving-looms, &c. In the foreground are various Tulip blooms, and on the extreme right is a similar sailing car wrecked. At the corner of the picture are small insets showing Pottebackers Garden and Club rooms at Haarlem and Hoorn. 26 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. make 100 rijksdaelers profit, I will make up the difference.”’ Waermondt replies: ‘‘ What a splendid proposal! but suppose I bought the bulb, how shall I get rid of it? Will the people come to me or must I go to them and offer it for sale?’’ Gaergoedt: “I will tell you. You must go to an inn; I will show you several, as I know but few where there are no collegiums (clubs). When there you must ask if there are any florists. When you are admitted into their club room, because you are a stranger some will quack like a duck, others will say, ‘I spy a stranger,’ but do not take any notice. Your name will be written on a slate (or black- board),’’ and then he goes on to describe the method of selling “met de Borden.”’ It was not permitted for one tc offer goods for sale, but one might ask what his neighbour had to sell, thus indicating that he himself had something to sell. He could say for instance: “I have more yellows than I can use, but I want some white.” Having found a possible purchaser, each, as Gaergoedt tells us, “ obtains a small slate or Borden, and each chooses an arbitrator; the seller then goes to the arbitrators, and demands, for example, 200 florins for his goods; the buyer goes to the arbitrators, hears what has been demanded, pretends to be in a rage, and bids as much too low as the seller has asked too much. The arbi- trators then fix the value, and write it on the slates of both parties, calling out the amount aloud. If both agree to the amount, the writing must remain upon the slate and the deal is finished. On the contrary, if both rub the writing out, the sale is off; if either agrees and allows the writing to remain, the other must pay the charges as fixed by the club; in some places two stuijvers, in others three, five, or six stuijvers. But if a sale is made the buyer pays half a stuijver on each florin, to the amount of three florins on each transaction of 120 florins or higher. This deposit was known as wine money, the seller allowing half of it back again to the purchaser upon settlement. The procedure of sales “ in het Ootjen ’’ is also explained by Gaergoedt. Waermondt inquires, “Is there no other way of dealing beside ‘met de Borden’?”’ Gaergoedt replies, “‘ Yes.” When the Schijven or Borden have been round, a drawing is made upon the blackboard (fig. 8). In the upper semicircle is written the thousands of florins, in the middle semicircle the hundreds of florins, and in the circle is “het Ootjen,’”’ in which the amount the highest bidder receives is written. Under the Ootjen, the tens of florins and stuijvers are written. Now one asks, ‘ Who will put something in the Ootjen?”’ If there is one willing, as there always appears to be, he places something in the Ootjen —say it is a “‘Gouda”’ weighing 30 azen. The auctioneer announces that the one who bids the highest shall receive a double stuijver, or three, four, five, or even six stuijvers, according to the custom of the place, and as the company have arranged. The bidding commences at, say, fifty florins, and continues till there is silence, or no further bids than, say, 1508 florins. Then the one at the slate or blackboard says, ‘“‘ Nobody bids, for the first time,’’ again, “‘ Nobody bids, before I finish.” With that he makes three strokes (probably through the amounts written, viz., the thousands of florins, hundreds of florins, and tens of florins) and draws a circle round, and then says, “‘ No one else, once,” ‘‘ For the second time,” “Third,” “Fourth and last time,’ and with this he draws a stroke THE INTRODUCTION OF THE TULIP, AND THE TULIPOMANIA. 27 through the whole, and if the seller agrees, the bulb is sold, and the wine money is paid as “met de Borden,” the purchaser receiving the money promised: to the highest bidder, which amounts were known as ‘‘ Drietjens.”’ The wine money, besides paying for light and fuel, supplied the members of the club with tobacco, beer, &c., for Gaergoedt replies to an inquiry from Waermondt about the wine money, and says: “ Yes. The wine money amounts sometimes to much more. I have often been to inns and eaten baked and fried fish and meat. Yes; chickens and rabbits, and even fine pastry, and drunk wine and beer from morning to Tutip GouDA. 350.

The crisis came unexpectedly, principally because connoisseurs had tired of their hobby, and had placed large 28 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. numbers of Tulips on the market, with the result that bulbs depreciated immediately. Then came the panic and everyone wanted to sell and no one wanted to buy. Waermondt tells us, that on February 3, 1637, a few florists met at an inn, and endeavoured to push the trade again by holding a mock auction, but without result. On February 24, 1687, delegates were appointed from the towns of Haarlem, Hoorn, Alkmaar, &c., who met at Amsterdam and drew up the following agreement: “That all sales of Tulips made to the end of November 1686 should be binding. Transactions after that date could be cancelled at the option of the buyer, upon payment of 10 per cent. of the amount purchased to the seller, providing notice is given before March 1637.” But this was not accepted. Gaergoedt gives us an idea of the times when, pointing to Waermondt, he says, ‘When my buyer pays me I will pay you, but he is nowhere to be found.” pd pa—eg 05 1637.

The Law Courts became crowded and, as no one knew what to do, the Magistrates of the towns were asked to intervene. A petition was handed to the Governors of Holland and West Friesland, at The Hague, pressing for the cancelling of all the trans- actions entered into during the past winter. In their reply the Court declared ‘‘there was not enough information in the papers furnished to enable the Court to come to a legal decision, but they advised the Magistrates to endeavour to induce the parties to come to terms in a friendly manner, and to keep the Court informed how matters were progressing.” A decree dated April 1687, issued by the Court of Holland, by which authority was to be given to the sellers to sell all Tulips sold for future delivery, after giving the buyer due notice, or hold them at their own risk, and that the buyer would be answerable for any differences in the amounts realized.

But as the edict promising legal adjust- ment never arrived, the contending parties were left to settle the matter between them as best they could. Many discontinued trading and came to terms with their creditors paying 5 per cent. or 10 per cent. to get out of their bargain to take the Tulips. Munting tells us that his father had, in 1686, sold to onein Alkmaar a few bulbs for seven thousand florins, on the following conditions :—That the sale should remain binding if there should be no fall in prices within six months, otherwise the buyer could refuse the Tulips upon payment of 10 per cent., but “as the fall occurred within the six months, my father received seven hundred florins for nothing, but he was obliged to keep his bulbs. He would have preferred to deliver the bulbs, and receive the seven thousand florins.”’ The caution displayed by the buyer seems to show that he was fully alive to the possibilities of a crisis. Munting also gives extracts of several of the transactions, from some ledgers kept during the craze, some of which are mentioned in “’t Zamen- spraeken ’’ of Waermondt and Gaergoedt. The example given below shows payment in kind.

One can estimate what an enormous amount these sums represented. 30 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. In 1733 and 1734 there was a minor revival of the mania, when enormous sums were paid for Double Hyacinths, which occasioned the reprinting of the ‘’t Zamenspraeken’ of Gaergoedt, and Waermondt as a warning; and in the ‘Florists’ Magazine’ of 1836 (vol. 4, p. 215) I find the following: “The well known taste of the Dutch for Tulips is not diminished. The new Tulip called the ‘ Citadel of Antwerp’ has been purchased for 16,000 francs (£650 sterling) by an amateur at Amsterdam.”’ At the present day new varieties sometimes change hands for large sums, but a repetition of the mania is not likely to occur. CUCURBITACEOUS FRUITS IN EGYPT. OL CUCURBITACEOUS FRUITS IN EGYPT. By Mr. T. W. Brown, F.R.H.S. Most of the crops in Egypt are grown under irrigation, which necessitates the adoption of methods of cultivation different from those followed in countries where rain is the immediate source of the moisture in the soil. Again, in districts where the ancient system of flooding the land once each year is followed, the agriculture is necessarily different from that practised on land now under perennial irrigation and watered at all seasons. If we also remember that the water-wheels, ploughs, and other implements employed are of the most ancient patterns, it will be seen that the peculiarities of Egyptian agriculture are varied and picturesque. Many Egyptian varieties of cultivated plants are of special interest. In this respect the somewhat numerous varieties of Kgyptian cotton will at once occur to the mind, but the Cucurbitaceous plants are quite as interesting and perhaps not so well known as the cotton. Although they are not indigenous to the country, the introduction of several of the most useful members of the family must have taken place at very remote periods. ‘We remember the fish which we did eat in Egypt freely, the cucumbers and the melons,’’ was the plaint of the Israelites after leaving the land of their captivity. Whatever fruit may be meant by the word ‘melons’ in this passage, it is interesting to note that similar regrets are very often expressed in regard to the sweet melons and water melons of the present day by people leaving Egypt. The kind of sweet melon most commonly grown, and known in Arabic as ‘Shammam,’ is a variety of the same species as the Queen Anne’s Pocket Melon— Cucumis Dudavm. The latter plant is also occasionally met with, but, as in other countries, it is of ornamental value only. It is called ‘Abou Shammam,’ which means “ the father of Shammams.”’ The ordinary ‘Shammam’—C. Dudaim aegyptiaca—is a most delicious melon. There are three varieties of it, viz. the ‘Geyeidy,’ . ‘ Weraki,’ and ‘ Besusi.’ The first is by far the most common. It is oblong in shape, about 30 cm. long, of an average weight of 24 kilos., lightly furrowed, dark green, but becoming yellow between the furrows when ripe. The flesh is greenish white, melting and sweet. The ‘ Weraki’ is a larger variety, but is less sweet than the ‘ Geyeidy.’ The best variety is the ‘ Besusi.’ The fruit is short, but it has a deeper and sweeter flesh than the others. This variety requires a comparatively heayy soil, and is grown chiefly on the island of Abou el Gheit, and Besus to the north of Cairo, whence its name. Owing to the delicacy of the skin, the greatest care has to be taken to protect the fruit from the direct rays of the sun. For this reason the cultivators usually sink the immature fruits in the soil, and dispose the branches so as to form a thick shade above. 32 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY Sickenberger in the “‘ Contributions a la Fiore d’Egypte’’ mentions a fruit which is intermediate between the ‘Shammam’ and the ‘ Abou Shammam,’ but I have not seen it. A very long club-shaped melon is sometimes cultivated on the banks of the Nile. This resembles the ‘Shammam ’ in colour and perfume, but is tasteless, and otherwise of poor quality. At Cairo it is called ‘ quattah saidy.’ Ube. melons belonging to Cucumis Melo are known in Kigypt as “qaoon.’ They are represented by several varieties, all, however, being either netted or winter melons. The Cantaloupes are scarcely known outside the gardens of a few Kuropeans. The best known of the netted melons is the ‘qaoon Santaouy.’ This is a small, globular, and strongly- scented fruit. It is somewhat deeply furrowed, and has a light yellow skin with a close network of raised lines. The flesh is thin, light orange coloured, and very juicy. It is a late variety of melon, and does not appear in the market until the latter half of July, whereas the ‘ Shammam ’ is ready in the middle of May. The ‘ Santaouy’ is grown chiefly in the Delta, but a netted melon is cultivated in Upper Egypt also, under the name of ‘ qaoon saidy.’ It is said to attain a large size, but the specimens which I have seen were not remarkable in this respect. It is a globular melon, somewhat deeply ribbed, and with a dark brown skin mixed with yellow and green. It has a thick sweet flesh of good quality. Of the smooth-skinned melons, the most important is that known as the ‘ qaoon beledi,’ which, like the ‘qaoon saidy,’ is cultivated chiefly in Upper Egypt. It is globular in form, and has a light yellow skin without furrows. The flesh is white, thick.and very sweet, the average weight of the fruit being about 35 kilos. At Cairo this is called ‘qaoon Doumeyry’ and sometimes ‘qaoon Sohagi,’ but neither this nor the ‘qaoon saidy’ comes to Cairo in large quantities. Other varieties are imported in large quantities from Smyrna, after the middle of August, when the Egyptian melons (Shammam) are finished. Mention must be made of an oblong melon called ‘ qaoon mahanaouy.’ The only place where I have known this to be cultivated is Sohag, in Upper Egypt. A native grower of that place informed me that it sometimes attains a length of 50 cm. Itis, however, tasteless and of little value. Apart from these long melons, the most remarkable Cucurbitaceous fruit in Egypt is that known as ‘agour’ —C. Melo Chate, L. (Naud). As De Candolle points out, the name of the cucumber in modern Greek is ‘angouria,’ “from an ancient Aryan root which is sometimes applied to the water-melon, and which recurs for the cucumber in the Bohemian ‘agurka’ and the German ‘gurke,’ &c.’’ The ‘agour’ of the Egyptians, however, bears no resemblance to a cucumber. It is oval in shape, but gradually tapering to a point at both ends. The length. of an average-sized fruit is about 40cm. It has a reddish-brown skin, covered with a close network of raised lines. The flesh is thin, orange- coloured, juicy, but not sweet. The ‘agour’ matures very quickly and appears in Cairo market in April. Coming at a time when no other melon fruits are available, it forms an important and popular food among the natives. It is usually eaten raw with sugar. | CUCURBITACEOUS FRUITS IN EGYPT. oo In Egypt meions are grown largely on the light loam found on the islands and the banks of the Nile when the river is low. The following is the system of cultivation practised. Trenches running in a transverse direction to the prevailing wind are dug in the silt bordering the water. The trenches are made 20 cm. wide, 30 cm. deep, and 90 cm. apart. A layer of decayed pigeon manure is placed in the bottom of the trenches, which are then refilled with soil. Farmyard manure is used where pigeon dung is not available, but does not give such good results. The seed is soaked ia water and germinated before sowing. It is then sown in holes about 40 cm. apart, and a row of maize-stalks fixed in the soil by the side of each trench, in such a manner that the maize leans over the young plants and protects them from the wind, while leaving them exposed to the sun. Where there is a danger of the plants being covered with drifting sand, low barriers are constructed around the plots. Four cr five seeds are sown in each hole, but when the seedlings have attained three or four leaves they are thinned so as to leave one plant only. During the growth of the crop the soil is hoed to keep it moist and loose. When the fruit begins to appear, the maize-stalks are removed and a second trench is often dug parallel with and close to that in which the plants are growing. This is filled with manure and soil in the same way as the first, and forms an additional supply of food for the plants. The best fruit on each plant is allowed to remain, the others being removed when small. These small fruits are in the case of the ‘Shammam’ known as ‘sirt,’ and in the case of the ‘agour’ they are called ‘hersh.’ They are eaten in the same way as cucumbers, but are in much greater demand and bring better prices than the latter. The ‘Shammam’ is grown almost always as a river crop. As the roots descend 60 cm. to 70 cm. into the soil, the water-level is sufficiently near the surface to enable the plants to grow without irrigation. The ‘qaoon Santaouy’ on the other hand, is cultivated chiefly on the high sandy lands on the edge of the desert, in which situations it is of course necessary to water the plants. The preparation of the ground, however, is the same. The ‘agour’ requires a more compact soil than the melons, and is therefore grown chiefly on basin lands which have been flooded during the previous autumn. In this case the seed is sown on the edge of a shallow furrow, and the manure applied when the seedlings have four or five leaves. Water melons are cultivated in the same way as sweet melons. They can, however, be grown on much poorer ground than the ‘Shammam’ and in situations where the sand is too loose for the ‘ Santaouy.’ The water melon is a very important crop, and is sown in large areas both on the river banks and inland. The number of varieties of red- fleshed water melons is large, but many of them are not well defined, intermediate forms making classification difficult. An attempt to do something in this respect was made last year by the Horticultural Society, by collecting and comparing fruits from various parts of the country. It was, however, found that it would be necessary to cultivate all the varieties together on the same soil for one or more years, in order to arrive at definite conclusions. The most distinct varieties are (1) the ‘beledi,’ a rather large, light green or grey fruit of medium quality, (2) the ‘saidi,’ which is dark green and has a firm, sweet flesh, and (8) the VOL. XXXV. D of JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. ‘Yaffaoui,’ which is a plain liight-green fruit with a red flesh of excellent flavour. Almost all the varieties have oblong forms in addition to the ordinary shapes. These elongated forms are distinguished by the name of ‘nims’ (ichneumon) and are spoken of as ‘beledi nims,’ ‘ saidi nims,’ &e. Of yellow-fieshed water melons, two distinct varieties are cultivated, viz. the ‘hegazy’ and the ‘Stambouly.’ The latter is somewhat rare. Both are thin-skinned fruits of excellent flavour. The ‘abou-hazam’ is a variety in which the flesh is rose-coloured in the centre and yellow next the skin. A white-fleshed water melon exists in Upper Egypt, but I have not seen this. The cucumbers constitute another crop of importance in Egypt. Of the ordinary cucumber (Cucwmis sativus) only one variety is grown. It is a strong-growing plant, with fruits about 25 cm. long at maturity. They are, however, always gathered when small, and in this state the flesh is crisp and of excellent flavour. In Arabic this cucumber is known as ‘ khiyar.’ The snake cucumber (C. flecuosus, L.), although not of the same importance as the common cucumber, is, however, grown on a large scale. In habit of growth and general appearance it resembles a melon plant. It produces cylindrical twisted fruits about 50 cm. long. They are light blotched with dark green, and covered with soft woolly hairs. This is the ‘fakus’ of the Arabs. It is not gathered until it has attained a large size, when it is consumed as a salad chiefly by the natives. The hairy cucumber (C. pubescens, Willd.) is another plant which resembles the melon, but the leaves are covered with short prickly hairs. It is known as ‘ quattah firany’ in Arabic. The fruits are cylindrical, generally straight, and about 25 cm. long when full grown. The skin is white, light green, or dark and light green mottled. It is covered with soft hairs and often striated with depressed lines. The fruits are gathered when small and eaten as a salad, or stuffed with meat and rice and after- wards cooked. Of the genus Cucurbita the most important plants in Egypt are the vegetable marrows. These are in the market at almost all times of the year. The varieties most commonly grown are (1) a green bush marrow known as ‘ cosa Skandarani’ and (2) a running variety with white fruit known as ‘cosa beda.’ As in the case of cucumbers, the fruits of vegetable marrows are always gathered when quite small. Apart from the vegetable marrows, the only plant belonging to Cucurbita Pepo culti- vated by the fellaheen is a large globular pumpkin called ‘ qara magreby.’ The fruit attains a diameter of about 35 cm., and a weight of 10 kilos. The flesh is white, and when cooked with rice and meat forms an agree- able dish. This plant, however, is not so common as the Naples Gourd or ‘ qara Stambouly’ (C. moschata), which is grown in all situations, with or without irrigation. The flesh is somewhat dry, of a pale orange colour, rather sweet when ripe, and slightly scented. As the fruit keeps in good condition for six months or more it is in use at all seasons. In addition to the ordinary variety, which has an elongated fruit constricted in the centre, a form with globular fruits is sometimes met with. The mammoth pumpkins—C. maxima—are grown to a very small extent in Kgypt. That most frequently seen is somewhat oval in shape, CUCURBITACEOUS FRUITS IN EGYPT. 35 with an average circumference of 1°25 m., and an average weight of 17-20 kilos. In the Cairo market it is known as ‘ qara Soudani,’ but this is evidently a misnomer. The retail price varies between 4s. and 6s. each. — The plants which now remain to be mentioned are the luffa, or sponge gourd, and the calabash. Although luffas are not exported to a great extent from Egypt, large quantities are used in the country for washing cooking-utensils, &c. They are grown everywhere—on fences, trees, out- houses, &c., but there is a ready sale for all produced. The ripe unpre- - pared fruits bring from 10s. to 16s. per hundred. Three varieties, all belonging to Lujfa aegyptiaca, are grown. ‘These differ chiefly in the length and thickness of the fruit. The ‘rumi tawil,’ which is the kind most valued, produces fruits 45-50 cm. long. The fruits of the calabash—Lagenaria vulgaris—assume many different forms. Some are used as receptacles for water, while others are used as floats for fishing-nets and as household ornaments. The only variety which is of any value asa food plant is that known as ‘ qara atraj.’ This has a straight cylindrical fruit, one metre or more long, with a light green skin and greenish pulp. Gathered in a green state, they are eaten cooked, or they may be allowed to ripen and be made into jam. The cultivation and marketing of the Cucurbitaceous crops give employment to large numbers of people. Donkeys laden with cucumbers and vegetable marrows may be seen coming into Cairo any morning during nine months of the year. Sweet and water melons are chiefly collected in boats and brought to Cairo by river. These cargos are mostly discharged at Giza, whence they are taken by camels, donkeys, and conveyances of every kind to the market, shops, &&. The unloading of the boats in the early morning forms one of the busiest and most picturesque scenes in Hgypt. Large numbers of water-melons and ‘agours ’ are also brought direct from the fields to Cairo by camels. The returns from an acre of melons or water melons vary between £20 and £40. As the expenses do not exceed £10, good profits are made by the cultivators. In view of this fact and of the large quantities of fruit grown, it is somewhat surprising that Egypt imports melons and water melons to the value of £66,000. In spite of the enormous consumption, however, there is no doubt that Egypt could quite easily supply her own wants. The principal reason why she does not do so at present is that the number of people who understand the cultivation is limited. The fellah is very conservative, and unless he has been taught to grow melons by his father or other relation, he is not likely to commence later in life. Experiments carried out on a large scale have also shown that an extensive and highly lucrative export trade may be established in long cucumbers and melons with Europe in late autumn. For the develop- ment of this part of the industry, however, it will be necessary to look to Huropean enterprise. D2 36 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. THE LILY OF THE VALLEY. By Miss H. C. Puiusricx, F.R.H.S. “Awake, O north wind; and come, thou south; blow upon my garden that its spices may flow forth.” Convallaria majalis—the Lily of the Valley. What a host of memories its very name conjures up! And we are carried away captive, for none can remember the time when he did not know and love this flower of fragrance; its beauty and its purity are all its own. Most of us are probably much more familiar with the Lily of the Valley as a garden flower than as a wild plant, but it is a true native nevertheless, and may in many places be found in abundance. You will bear in mind that it really is a plant of the woods, so that it is only there, or in sheltered coppices, that there is any reasonable hope of finding it. We may here, however, advantageously point out that in foliage and general effect the broad-leaved garlic is very similar to the Lily of the Valley (save in perfume), and both are found in the same situation at the same period of the year and that more than one of our friends have been previously disappointed by confounding the two. Yet I think we shall all agree that the pure white clustering starry blossoms of the garlic are very beautiful in themselves, and have a full claim to be admired for what they are—not scouted for what they fail to be. Londoners will hear with interest that in the time of the great botanist Ray, the Lily of the Valley grew abundantly on Hampstead Heath. In 1590, in St. Leonard’s Forest near Horsham in Sussex, where the Lily of the Valley used to be seen in profusion, the local legend tells us that the patron saint of the district, St. Leonard, waged a mortal combat for many hours with a great and terrible-dragon. Though in the end victorious, the saintly dragon-slayer by no means escaped scatheless, and these large masses of snowy blossoms scattered over the forest sprang from his blood shed during the dread encounter. Anyone who in this sceptical age has doubts can go and see the flowers for himself. In the east of England, the Lily of the Valley has made a dwelling place in both Essex and the sister county Suffolk, notably in Woodham Mortimer, the . High Woods near Colchester, and in Bentley Woods near Ipswich. It is also common in many other English counties, very local or almost wanting in others, while in Ireland and Scotland it would appear to be scarcely indigenous, though it is indigenous in most parts of Europe from Italy to Lapland. In the woods of Hileriedle, in the neighbourhood of Hanover, the ground is covered with them; these woods are visited every Whit Monday, we are told, by numerous parties from Hanover, who gather these delightful May flowers. It is sometimes called the May lily—many of the old names of plants, as the pasque flower, Lent lly, St John’s wort, and numerous THE LILY OF THE VALLEY. 37 others, having reference to the date of flowering. It is in France the “Muguet de Mai’”’; in Germany the “ Maiblume.” Its specific name, majalis or maialis, signifies “that which belongs to May,’’ hence the old astrological books place the plant under the dominion of Mercury, for Maia, the daughter of Atlas, was the mother of Mercury or Hermes. It is also called Convall Lily and Lily Constancy by the old herbalists, and in some parts of the country its local name is “‘ Ladder to Heaven.” Its spotless purity of colour and lowly humility were probably the cause of the bestowal of the last name—a name that has no doubt descended from medieval times. The old monkish herbalists often based their nomenclature on associations of a religious character, and united their plant names with the legends of the saints or the services of the Church’s calendar. “To the curious eye A little monitor presents her page Of choice instruction ; with her snowy bells, The Lily of the Vale. She not affects The public walk, nor gaze of noonday sun ; She to no state or dignity aspires But, silent and alone, puts on her suit, And sheds her lasting perfume, but for which We had not known there was a thing so sweet Hid in the gloomy shade.’’—Hvrpis. Again— “And their breath was mixed with fresh odours sent From the turf like the voice of an instrument.” As an ornamental plant few of our native species have a greater claim to a place in the garden, and may I say in our hearts, for few others can boast of so rich a fragrance or so delicate a beauty ; added to these charms it is most easy of cultivation, requiring only to be placed in a shaded corner. The generic name Conyallaria is from the Latin word for valley, and is bestowed in obvious reference to the sheltered woodland dells in which the Convall Lily finds a congenial home. The root of the Lily of the Valley is fibrous and perennial, extending a little below the surface of the ground, and reaching to a considerable distance. The leaves grow in pairs, their stalks sheathing one .within the other. One of these leaves is often larger than the other, as all know, and also that they are very simple in form and deeply ribbed; when forced the leaves are of a much paler green and finer texture, and they take a deeper and more sombre green out of doors as the season advances. The flower stalk springs from the root and is about equal in length to the leaves. It bears a loose raceme of drooping bell-shaped flowers of pure white ; hence in Beaumont and Fletcher’s sonnet on the spring we find them referred to as “lilies whiter than the snow.” In its wild state the blossoms are rarely succeeded by the fruit, but it produces it readily under cultivation. The fruit is rather a large berry, something in size between a fine black currant and a small cherry, and of a brilliant orange red. Our friends in the Antipodes are sighing for the lily fair, and have, I have recently been told, tried more than once to get the plants from England; but they will not, as our friends north of the Tweed have it, “carry,” and ere they 38 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. arrive they are dead. ‘The only resource left is to send out the seed, and this I am doing. It is hardly necessary to say much upon the mode of cultivating this universal favourite: it delights in moisture and partial shade, and in a good light soil it loves to penetrate its fibrous roots. It is found in mountain copses sheltered by shrubs, and in the forest under trees. It is well to have a plantation of Lilies of the Valley upon a southern aspect if you want the flowers early, and in succession, for by this means they may be gathered a fortnight or three weeks earlier than otherwise—I am of course dealing with the days before retarded lilies were known—give rotten manure as surface dressings and plenty of moisture during active growth. ‘The chief point to guard against in outdoor cultivation is frost, this being destructive to the blooms which appear with the leaves. A few spruce or other evergreen branches placed sparsely over the beds afford efficient protection, and a beneficial shelter encouraging growth. Preference should be given to a soft loamy soil well enriched with rotten manure, though sometimes fine lilies may be grown in rather heavy loam. In preparing soft loam it will be best to give a liberal admixture of leaf soil and sharp sand. Whatever the soil may happen to be it should be moderately firm before planting. The best time for planting is in the early autumn, as soon after the foliage has decayed, selecting the crowns singly and dividing them for beds likely to remain undisturbed for several years. The crowns may be planted two, or even three inches apart, as they do not become crowded so soon as to require thinning out. It is a good plan to cover the surface after planting with one or two inches of rotten manure, thorough maturity being secured only by constant applica- tions of water, weak manure-water being the most efficacious. Treated thus with annual dressings of manure the beds will continue in good “heart’’ for years, and bear fine blossoms in abundance. When the plants become crowded with shoots they should be thinned out, or, better still, lifted and replanted, for weakly or blind crowns tend to retard vigorous growth. The Lily of the Valley is now largely forced into flower early, the roots being often imported from the Continent, where they are grown and prepared for the purpose. It may be naturalized, too, in any place sufficiently shaded and moist, and it soon spreads into broad masses. There is a variety with foliage striped with gold and another with double flowers, but the latter is not pretty. The finest form is called “Fortins,’’ which is much more robust than the common kind, having larger flowers; but in spite of this I think the smaller and familiar Lily of the Valley we found in the woods in our childhood is the one which lies the closest to our affections. The Lily of the Valley possesses a most beautiful curve, added to its many other charms, which makes it so perfect as a decorative flower, and when associated with blue forget-me-not—Myosotis palustris, found srowing by river banks, streams, and ditches in June, July, and August— the combination is delightful—the harmony is perfect. I would suggest that the lilies be arranged at the top of a glass vase, the forget-me-not at the base. Such vases are easy to get, and clear glass (not coloured) lends itself best, I think, to this arrangement, coming nearer to nature, and so nearer to the beautiful and the true. CHINESE PASONIES. 39 CHINESE PALONIES. By Rev. W. Winks, M.A. THE Peony found so very commonly in gardens is Paeonza officinalis. It has three well known double varieties—one a deep blood-crimson, another dark rose fading paler, and one called white which opens a pale rose-pink and gradually fades to a dingy, transparent white; it is often known as ‘ Adelaide.’ Of these the first-mentioned is by far the best. All three are comparatively common and have a distinctly unpleasant smell, reminding one a little of crushed ‘ ladybirds.’ Why, then, are the Chinese Pzonies so much less often met with? Is it that people do not know of them—do not know how many varieties there are, and of what lovely colours and glorious form and pleasant scent ? for most of them surpass the modern rose in fragrance. Or is it more probable that people in this twentieth century are in such an impatient hurry that they will not give the Chinese Pony the time it needs to establish itself and grow into the marvellously beautiful plant it will be- come in four to five years from planting? Their cultivation is of the very easiest. ‘They should be planted, only just below the surface, in the last week in October or the first in November, in ground that has been double- trenched, as they love to send down their thick, fleshy, tuberous roots deep into the soil. Plenty of good rotten dung should be dug in in the trenching, as, like roses, the soil can hardly be too rich for them. They want abundance of room and light and air and moisture (but not undrained wetness), but if sheltered from the prevailing wind the less will the blossoms suffer. If grown, as they deserve to be, in beds, they should have a top dressing of old rotten dung put on at the end of February, and if in at all a dry position they should have plenty of water, with a little chemical manure from the end of May till blooming time is over. To have fine flowers the very weak shoots should be removed at an early stage of their growth ; and later on the side-blossom buds should be removed from the strong shoots that have been left; as soon as they are negotiable. A well-grown plant will require three or four short stakes on the outside of the clump, with encircling tar twine, to prevent the heavy blooms bringing the whole plant to the ground. Among the very best varieties are— ‘Canari,’ white with a faint tinge of yellow. ‘Charles Binder,’ and ‘Ceres,’ very similar with pink guard petals and yellow and white centre. ‘Duchesse de Nemours,’ the best white with ivory centre. It is often sold under the name of ‘ Whitleyi.’ ‘ Alba Superba,’ the largest of all, loosely double and worthy of all the superlatives imaginable. (Fig. 12.) ‘Triomphe de l’Exposition de Lille,’ silver-pink with yellow stamens, loosely double. 40 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY, ‘Solfaterre,’ good early white tinged with yellow. ‘Madame Callot,’ pale flesh, very large and very double. ‘Philoméle,’ bright pink guard petals with a yellow centre. ‘Reine des Francais,’ pale pink guard petals with white and pink centre very beautiful. ‘Belle Chatelaine,’ a very fine pale pink. ‘Miss Salway,’ ivory yellow. ‘Festiva Maxima,’ paper white with crimson splashes, ‘Monsieur Rousselon,’ loose blush white with prominent yellow stamens. ‘Princess Beatrice, bright pink guard petals with ivory and pink centre, somewhat like ‘ Reine des Francais.’ . ‘Princess Nicholas Ribere’ or ‘ Ribesco’ (it goes under both names), silver pink guard petals, ivory yellow and pink centre. | ‘ Alba Maxima,’ another good white. ‘Princess Patricia,’ blush guard petals with ivory centre. ‘Lady Leonora Bramwell.’ For those who like a pink that seems as if it had a tinge of blue in it this is a very fine plant; very free- blooming, strongly rose-scented. ‘Marquise de Lorne,’ silver pink with yellow stamens. ‘Marie Jaquin,’ exactly like a white water lily, very beautiful, ‘Vanderbilt,’ pink guard petals, yellow centre. ‘Frances’ and ‘ Alexandrina,’ two good pinks. But perhaps this list is too long. If so take— ‘Alba Superba’ ‘Duchesse de Nemours’ and ‘ Festiva Maxima,’ three very fine but quite distinct whites. ‘Reine des Francais’ and ‘ Philoméle,’ both indispensable. ‘Belle Chatelaine,’ ‘ Frances,’ and ‘ Marquise de Lorne,’ three distinct shades of pink. Add to them ‘Princess Nicholas Ribere’ (or ‘ Ribesco’) and ‘ Marie Jaquin,’ and you have ten of the best. Buta really great difficulty is to get them true to name. For instance, a worthless pink has done duty before now for the glorious white ‘ Duchesse de Nemours’ which is sometimes labelled ‘ Double Whitleyi.’ ‘Reine des Francais’ and ‘ Philomele’ are also” sent out under misleading English names, and how that intercourse with the Continent is so easy and so frequent the practice of rechristening foreign-raised plants by English importers cannot be too strongly con- demned. The figures are from photographs taken in the garden at Coombe House, where these wonderful plants are grown to the utmcst perfection, and where they have stood undisturbed for eleven years, giving an equally magnificent display annually since the third year from planting.

METEOROLOGICAL OBSERVATIONS AT WISLEY IN 1908. 41 REPORT ON THE METEOROLOGICAL OBSERVATIONS MADE AT.THE SOCIETY'S GARDEN AT WISLEY IN 1908. By Mr. R. H. Curtis, F.R. Met. Soc. THE meteorological record at the Society’s Garden at Wisley has been maintained without break throughout the year, and that the observers, Messrs. Frazer and Wallis, have taken a keen interest in their work is shown by the careful way in which the record has been kept. ‘The instruments were examined and compared with standard instruments in July, and the station was then found to be in excellent order. The weather of 1908 was in no respect very exceptional. The temperature was on the whole about the average, there were some warm spells in June and July when several times 80° was exceeded, and again at the close of September and beginning of October when the minimum remained: above 60°. Bright sunshine was more abundant than usual over the southern half of England, and rather less than the average elsewhere. Rainfall was about the average in Scotland and Ireland, about 5 per cent. less than average in Wales, 10 per cent. less in North England, and 14 per cent. less over the southern half of Kngland. Gales were not numerous, thunderstorms also were less frequent than usual, but there were some severe snowstorms, the melting of the snow causing floods in some districts. The observations for each month are as follows: January.—The weather of the first half of the month was in some- what marked contrast to that of the latter half, the former being on the whole fair and cold, whilst during the last two weeks it was generally dull, and for the season rather mild, but with an unusual amount of fog. The average temperature for the month was in most places somewhat below the normal, and during the first week some low minima were recorded, the screened thermometer at the Garden falling to 15°°7, which was the lowest point reacked until the last day but one of the year. Over the greater part of England the fall of rain was considerably below the average, and in,some districts it did not amount to an inch for the entire month. At Wisley the total was just over an inch and an half, but of this amount an inch and a quarter fell on one day (7th), the remainder being distri- buted over nine other days. In some parts of the kingdom, however, there were very heavy falls, and upwards of an inch fell in twenty-four hours at several places. ‘The winds experienced were pretty evenly dis- tributed round the compass except for the quadrant from east to south, from which they seldom blew. Bright sunshine was generally well above the average, and at some stations in the south of England it amounted to 40 per cent. of the possible amount; at the gardens daily amounts of six hours and upwards were registered on five occasions. 42, JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY, Observations made at: Wisley : Mean temperature of the air in shade ae as Sp OS Highest 9 as . ie ee ... 93° 5 on the 27th Lowest ee . 5 ie nee BApraied lesa? retaet eral 6,040 Lowest - on the grass aaa he Lae OU Oe Sat hcamdal a tia Ab lft, Ab Dit. wAgait: deep. deep. deep.

There were 58 hours of bright sunshine, equal to 23 per cent. of the greatest possible amount. There were 13 days on which no sunshine was recorded. February.—The weather of February was marked by a persistence of westerly winds, which during the latter half of the month frequently attained considerable strength, and were accompanied by a good deal of wet weather. It was, however, warmer than February usually is, but whilst there were no very severe frosts neither were there any very warm days, so that there was but a moderate range of temperature. The coldest period occurred at the close of the second week, when the screened thermometer in the gardens fell to 22°, but at the close of the month a keen cold wind with squalls of rain, and in many places of hail and snow, occasioned a spell of weather which, although not so cold, was perhaps more generally disagreeable. The rainfall was below the average over the southern half of the kingdom, but rather above it in the north. At Wisley the fall, which was spread over fifteen days, only amounted to 0°85 inch, and in many districts it was less than an inch. The distri- bution of bright sunshine was peculiar, since the largest amounts were recorded over the north-eastern districts and the smallest in the west. At Wisley the total duration was eighty hours, and at many places in the west, which usually have the largest amounts, less than 50 hours were registered, whilst in Northumberland and on the east coast of Scotland the total ranged from 100 to 111 hours. , Observations made at Wisley: Mean temperature of the air in shade 5g. sak Boy bt 41°5 Highest i" 3 ‘ ue 74 ae nee 53°°8 on the 17th Lowest ‘ 53 Py she whe ce tie 22>*Oo ae wean Lowest ee on the grass... ane Bes ah te DiC A lott At 1ft.

METEOROLOGICAL OBSERVATIONS AT WISLEY IN 1908. 43 The prevailing winds were from south-west and west. The average velocity of the wind was 83 miles an hour. There were 80 hours of bright sunshine, equal to 28 per cent. of the greatest possible amount. There were 4 days on which no sunshine was recorded.

March was a month of continuously unsettled weather, accompanied by winds from nearly every point of the compass, although those from 44 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. westerly points predominated. The temperature was very generally below the normal, whilst the rainfall was everywhere in excess, and hail and snow were not infrequent. The amount of bright sunshine was with few exceptions less than the average, and the weather of the month may be summed up as cold, wet, and windy, and generally unfavourable for all farm and garden work. Occasionally sharp frosts were experienced, and on the night of the 15th the screened thermometer at Wisley fell to 23°°3, and the thermometer exposed upon the grass to 16°°8, whilst another grass thermometer exposed in a lower part of the garden fell a degree and a half lower. But throughout the month there was an absence of really warm days, the highest temperature reached being only 56°°3 on the 24th, when a westerly wind blew and the sun shone brightly throughout the greater part of the day. It was to this absence of spring- like warmth rather than to the occasional occurrence of somewhat low temperatures that the low average temperature and the general back- wardness of vegetation were due, the month being one of the coldest Marchs on record.

The average velocity of the wind was 74 miles an hour. There were 111 hours of bright sunshine, equal to 30 per cent. of the ae possible amount. There were but 3 days on which no sunshine was recorded. April.—The weather of April was in some respects very remarkable, the persistent cold winds from northerly quarters keeping the temperature so low that the month ranks as the coldest April experienced for nearly forty years. The coldest snap was on the 8th and 9th, when the un- screened thermometer at the gardens fell to 17°; but from the 13th to the 15th, and again from the 18th to the 25th, although the cold was less severe, the thermometer on the grass fell several degrees below the freezing point nearly every night. In some parts of the kingdom, however, the low readings at Wisley were greatly surpassed, a temperature of 4° having been obtained on the ground at Balmoral, 9° at Huddersfield, and less than 15° at many places. During the last ten days of the month there were frequent snowstorms, the worst occurring on the 25th with a severe gale, the snow falling to such a depth that railway traffic became disorganized, road traffic was completely stopped in many districts, and much damage was done to trees and shrubs. The rainfall over the greater part of England and Ireland was above the average, but in METEOROLOGICAL OBSERVATIONS AT WISLEY IN 1908. 45 Scotland it was rather below it. Bright sunshine varied from about 100 hours on the eastern coast to rather less than 200 hours in the south- west; at Wisley 145 hours were registered, or 35 per cent. of the greatest amount possible.

There were 145 hours of bright snahine: equal to 35 per cent. of the greatest possible amount. There were 4 days on which no sunshine was recorded. May.—A feature of the weather of this month of interest to gardeners was the absence of low night temperatures, the mean of the minimum temperatures being generally a good deal above the average, whilst in many places the lowest point reached by the thermometer was above the lowest which had been observed in May for a good many years past. This was largely due to the cloudiness of the sky, by which the radiation of heat from the ground was greatly checked whilst the temperature of the soil steadily increased, the readings of the thermometer at Wisley one foot below the surface being 16° higher at the end of May than at the beginning of April. The winds also were from southerly and westerly points; and although the amounts of sunshine registered were generally rather under the average the deficit was not large, and in many places between 40 per cent. and 50 per cent. of the possible total was recorded. Thunderstorms with heavy falls of rain or hail were not infrequent, but generally speaking the precipitation was below the average for the month.

The prevailing winds were from between south and west. The average velocity of the wind was 7 miles an hour. There were 192 hours of bright sunshine, equal to 40 per cent. of the greatest possible amount. There were but 3 days on which no sunshine was recorded. June.—The weather of June was generally fine, with a good deal of sunshine and less rain than the average. A cool northerly wind which was experienced about the 5th and 6th brought the temperature down somewhat, and there was some changeable weather towards the middle of the month, but this was followed by warm summer-like weather which lasted till the close. The amount of rain which fell was in most places less than the average, the amount recorded at Wisley being only 1°72 inches, of which 0°71 inch fell in one day, and it was only on six days that there was any rain to measure. The amount of bright sunshine was generally above the average, and exceeded 280 hours at several places in the south of England. A violent squall, which, however, was of very limited area, was experienced in the Thames valley in the course of the night of the 1st, and did a considerable amount of damage to small trees in Bushey Park and elsewhere ; and another of somewhat similar character visited North Herts on the afternoon of the 4th, in thundery weather, and travelled in a §.S.E. direction for about six miles, scattering hayricks, overturning loaded carts, and levelling trees and other obstacles in its path.

There were 266 hours of bright sunshine, equal to 55 per cent. of the greatest possible amount. There were no entirely sunless days. July.—The fine weather with which June closed continued during the opening days of July and produced some high readings of the thermo- meter over all the central parts of England and even in many parts of Scotland. After the first few days, however, a change took place to un- settled weather, a good many small depressions passing across the country bringing with them rain, which in some districts was very heavy and lowered the temperature considerably. The wet weather ceased about the 18th, and from that day to the close of the month no rain fell at Wisley. The fall of rain was, however, patchy, some districts having much less than the average, whilst others, as for example the north-west ew a. = a) METEOROLOGICAL OBSERVATIONS AT WISLEY IN 1908. AT of England, had considerably more. Winds blew chiefly from westerly points and at times rather strongly, and there were several thunderstorms. Bright sunshine was plentiful over southern England, but at some places in the north it was very deficient, not amounting to 20 per cent. of the possible amount.

August.—The winds throughout a great part of this month were from west, north-west or north, and consequently cool, so that there was an entire absence of very hot days, although the weather was generally fine and dry. The nights were warm, except for a short interval in the middle of the month, when the grass thermometer fell to 35° at Wisley, and: to below the freezing point at several places further north. After the third week the character of the weather entirely changed and a succession of disturbances passing across the kingdom brought with them unsettled, showery weather, and in some parts heavy rain. On the whole the month was a sunny one, Wisley having very nearly 50 per cent. of the possible amount, and many places on the south coast having upwards of 60 per cent. The frequency of rain varied a good deal in different localities, but whilst the fall was deficient over the northern half of the kingdom and in Ireland, it exceeded the average over the southern counties. | Observations made at Wisley: Mean temperature of the air in shade ae Lah ote ei Lge 59°°9 Highest ed ~ ‘ ae ae fe me 81°-2 on the 3rd Lowest ec 3 “A eels Lat = aes 4129-932 th Lowest on the grass 332 eee a3 ye acs ai beeen AAS At ft) Ad Otte ee At 4 ft deep. deep. deep.

At the beginning of the month, with a cool northerly wind, the thermometer very generally failed to reach 55°, whilst at its close it rose to 77° at Wisley, METEOROLOGICAL OBSERVATIONS AT WISLEY IN 1908, 49 that being the highest reading recorded there for the month, and to upwards of 80° in some parts of the kingdom. Insome places there were sharp ground-frosts also at the opening of the month, chiefly in the north and over central England, but at Wisley 32° was reached only on the night of the 12th. In Berkshire a heavy storm of rain, hail and snow was experienced on the 11th, and at Canterbury a deluge of hail and rain accompanied a thunderstorm on the same day. The rainfall was consider- ably more than the average in the north but was much below it in the south of England; the total fall at the Garden was 1:29 inches, whilst on the Essex coast it did not exceed an inch.

There were only 2 days on which no sunshine was recorded. October.—The remarkably warm weather with which September came to a close continued on into October, and the month was one of unusual mildness. During the first four days the thermometer rose to quite an exceptional height, the maximum readings being the highest recorded in October for nearly half a century. At the Garden 77° was the maximum, but at some stations in England 80° was exceeded, and a reading of 78° was recorded so far north as Banffshire. The third week, although not cold for the time of the year, was the coolest period of the month, and ground frosts occurred two or three times, but as the month drew to a close the thermometer rose again, and on the 29th a shade reading within 2° of 70° was obtained at Wisley. On the whole the month was the warmest October experienced for many years. The temperature of the soil kept high, as might have been expected from what has been already said, and the mean at one foot below the surface was only 2° below the mean for September. The fall of rain was generally below the average, and at many places a large part of the total fall fell in one day; at Wisley nearly half of the monthly amount fell on the 18th, and at many places in the south and south-west of England large falls of more than two inches were recorded at about the same date; at Weymouth four inches fell in about five hours. The winds were mostly from southerly points, and the amounts of “bright’’ sunshine registered were generally above the normal, the percentage of the possible sunshine amounting to nearly 50 per cent. at many places.

The average velocity of the wind was 33 miles an hour. There were 113 hours of bright sunshine, equal to 35 per cent. of the greatest possible amount. There were 6 days on which no sunshine was recorded. November.—The most noticeable feature of November was the mild- ness of the weather throughout the month, and although as a rule the temperature was not remarkably high, yet readings of 60° and upwards METEOROLOGICAL OBSERVATIONS AT WISLEY IN 1908. 51 were recorded at many widely separated places, generally at the com- mencement of the month. At the close of the first week there was a short spell of colder weather, the thermometer falling to below 20° at Wisley, and sharp night frosts being experienced generally from the Sth to the1lth. On the grass the temperature fell still lower, 16°°5 being the lowest point reached at Wisley, whilst at Greenwich it dropped to 9° and in Mid-Wales to 7°. Taking the month as a whole it was the warmest November experienced for several years. Winds from the south- westerly quadrant predominated, but over the southern part of the kingdom it frequently blew from northerly and easterly points. The amounts of sunshine recorded were as a rule above the average, and varied from about 40 per cent. of the possible amount in the Channel Islands to only 8 per cent. in the Shetlands ; at the Garden it amounted to 29 per cent. Rain- fall was below the average except in the northern parts of the kingdom, and the number of days on which rain fell was generally small. Over the greater part of the Midlands the fall amounted to less than an inch, and to less than two inches over the eastern half of the kingdom from the Channel to the Moray Firth.

The average velocity of the wind was 53 miles an hour. There were 76 hours of bright a ashines equal to 29 per cent. of the greatest possible amount. There were 8 days on which no sunshine was recorded. December.—The weather of December was in no way remarkable until the last week of the month. The temperature was rather above the average, and night frosts were rare and nowhere severe. The winds blew almost constantly from the south-westerly quadrant, and were not only mild but also of moderate strength, and although rain fell frequently there were no very heavy falls. At Christmas time, however, a change set in; the wind shifted to the north-east, and a current of cold polar air swept across England, bringing with it severe wintry weather, and in many parts deep snow. A screen temperature of 1° was registered at Liphook, and at Wisley a reading of 7°°5, whilst on the ground the grass minimum thermometer fell to zero at Wisley, and to 8° below zero at Epsom. At many places the snow buried the thermometer and rendered its record useless. In Scotland the cold was less severe, and in Ireland it was scarcely felt, as was also the case in western Cornwall.

NOTES ON SOME HYBRID TUBEROUS SOLANUMS. 53 NOTES ON SOME HYBRID TUBEROUS SOLANUMS. | By Rev. J. Aikman Parton, M.A., B.Sc. Iy the summer of 1907, among other crosses, I effected two on S. Maglia, the white-flowered Chilian wild potato. Twenty-five berries were formed and grew (pollen of several different varieties, wild and cultivated, being used), but of these only two were found to contain sufficiently matured seed—one seed in each berry. The pollen parents were (1) S. “etwbherosum”’ (so-called),* and (2) a Chilian cultivated variety (Yrancesa Col.). The two resulting seedlings showed a marked difference from the beginning, the former being much more vigorous. (1) S. Maglia x S. “etuberosum’’?: sown March 28, 1908; first flower July 1, first berry July 6 (thirty-one berries altogether) ; taken up December 7 ; tubers white [«]. This seedling, a very strong one, resembles S. “ etwherosum’’ in having a green stem and soft foliage, but the leaflets are much larger, like those of the cultivated sorts, from which, indeed, they cannot be dis- tinguished. (The foliage of the parents is quite distinct, and in each case distinct from that of the cultivated forms.) ‘The plant has the branching habit of S. Maglia fully developed, almost every node for a good way up the stem producing a branch. The leaves seem immune from attack by the fungus Phytophthora infestans. The corolla is large, measuring about two inches from tip to tip—very much larger than that of either parent—mid-violet in colour, with white tips. (S. Maglia has pure white flowers, S. ‘“‘ etwberoswm”’ pale lavender (No. 207, 1),7 with violet tinge on back rays.) The trusses are very large and abundant. The stamens are large and finely formed, straight (those of S. Maglia are usually curved inwards) like those of S. “etwheroswm,”’ but much larger, and full of fertile pollen. The style very slightly projects beyond the stamens. Thirty-one berries have formed on the plant, all due to artificial pollin- ation. ‘The berries are unlike those of either parent, being large, round, of a beautiful green colour (No. 243, 4, shading to No. 271, 2 and 1), with- out spots, quite like the common potato berries. (S. Maglia has laterally compressed round berries; S. “ etwberosum’”’ has ellipsoidal white-spotted berries, and in both they are much smaller than those of the hybrid. The tubers are in colowr quite white (those of S. Maglia are violet (No. 191),7 those of S. “etwberoswm’’ brownish-yellow-white), but of the same shape (although this varies greatly) as those of S. Maglia. They occur at the ends of short runners, as in some cultivated forms. I have effected a number of crosses with the pollen of this hybrid on cultivated varieties, e.g. ‘ Jeanie Deans,’ ‘ Duchess of Cornwall,’ ‘ Eldorado,’ ‘Ninetyfold,’ ‘Peacemaker,’ &c., showing that it is quite fertile. The seeds produced as a result of these crosses have been sown. * Tts ‘‘ selfed”’ seedlings seem to show that this is a hybrid. (See note p. 56.) t These numbers refer to the colour numbers in the Répertoire des Couleurs. 54 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. (2) S. Magha x a Chilian cultivated variety (francesa Col.) : sown March 28; first flower opened August 8; taken up November 11 [/3]. This seedling entirely resembles S. Maglia in general appearance, and would at first sight be taken for that plant. It has dark branching stems and sparse, firm foliage, which is subject to disease about equally with S. Maglia. The flowers are scanty, the trusses small. The corolla is large, of mid-violet colour, with white tips (very like that of No. (1) seedling in size and colour)—one truss had pure-white flowers—the stamens strong, and straight, similar to those of No. (1), but not having so much or so fertile pollen ; the style is longer, projecting beyond the stamens like that of S. Maglia. This plant had no berries, although every flower was pollinated. The tubers are in colour violet (No. 191, 1 and 2), like those of S. Maglia, of good shape, rounded oblong, smaller at the “rose”’ end than at the base, with white eyes. They were all found near the top of the soil in the pot, and are entirely free from disease, although the leaves were affected. It is difficult to get seed from S. Magla. Again this summer, - although on one of my plants fifty-five berries set and swelled (due to many different crosses) only five of them have contained mature seed—one seed in each. In 1907 I also effected a cross of S. “etuberosum’”’ x ‘ Duchess of Cornwall,’ and append brief notes of the fourteen seedlings resulting. The two dates at each are those of flowering (first flower open) and of taking up. They were all sown on March 19, 1908 :— 1. July 15, September 15: White flower, would not “self”; fifty tubers, same as those of S. ‘‘etwberoswm,” three slightly diseased ; 192 oz. 2. July 16, October 81: Flower almost white, dark lavender rays at back, downy ; sepals greenish, downy ; tips green; three tubers, small, round, violet-black. 3. July 18, November 10: Flower pale mauve; back of petals rich mauve, rays hirsute; sepals brownish, hairy, tips brown; eleven tubers, red (No. 170, 3; or 105, 4); deep eyes. 4, July 19, Sooteaiie 28 : Flower lavender ; back of petals mid-violet ; large anthers; little pollen; sixteen tubers, sean white, five eae diseased ; deus eyes; coarse. Very strong plant. 5. July 30, September 28: Flower uniform mauve; small truss ; nine tubers (besides five largest diseased), round, oblong, white; fine ; second growth started, one bud half-inch long. (Too long in ground.) 6. August 1, September 28: Flower white, tinged creamy-pink ; six tubers, oblong, white, small at end of runners; foliage diseased, September 18. 7. August 8, November 23: Flower not noted; very strong plant ; 102 tubers, white, good size, many of good form, round; large lenticels. 8. August 4, not noted: Flower pale carmine-mauve ; eleven tubers, fine, kidney form, white, flesh yellowish, two diseased. 9. August 5, September 23: Flower nearly as S. ‘‘ etwberoswm,”’ very pale mauve at centre, rest nearly white; pollen abundant; one small coloured tuber forming ; foliage destroyed by disease September 15. | 10. Not noted, September 28: Sixteen tubers, white, round, fine, an NOTES ON SOME HYBRID TUBEROUS SOLANUMS. 55 improved “ etwherosum’’ ; second largest tuber diseased, several pushing November 24. (Too long in ground.) 11. Not noted, September 14: Highteen tubers, white, round, early, no disease ; yellow flesh, very fine; two pushing November 24. 12. Not noted, September 15: Poor plant; roots all gone; five tubers. 13. Not noted, September 23: Eight tubers, white with violet tint; good. 14. No note made. Another cross of S. “ etwberosum”’ x Chilian variety gave twenty- two seedlings, some noteworthy. I may mention the remarkable fact that a seedling plant of S. “etuberosum’’ “selfed’’ produced 481 tubers (probably 500, as some were lost), weighing over 3 lb., white, with no trace of disease. The flower of this plantis white tinged with violet, the back of the petals being pale violet with white edges; the plant very strong, foliage also showing no disease. [Across of this with [a] has given two good berries.] These selfed seedlings were planted out too late for the tubers to attain their proper size, but I have never known a cultivated seedling to produce so many tubers, although I have raised upwards of 13,000. 56 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. NOTE ON “SOLANUM ETUBEROSUM.” By Tae Epiror. In 1835 Dr. John Lindley, F.R.S., F.R.H.S., figured and described in the * Botanical Register,” t. 1712, under the name of Solanum etuberosum, a species of Solanwm which had been introduced from Chile by the Royal Horticultural Society some years before. He describes the plant as a hardy perennial and states that ‘it bears rich clusters of deep purple blossoms, with a golden yellow centre, from July to October, and is very easily multiplied by dividing its stout rooting underground stems.” “ Although extremely similar to the Potatoe (szc) in appearance, yet its larger and more compact flowers and its want of power of producing tubers renders it a proper plant for the flower garden.”’ ‘¢ There can be no doubt that this is a species essentially distinct from the Potatoe, and yet it is impossible to point out any character by which it is to be positively distinguished, except the want of tubers and the smoothness of the calyx and flower stalks; these latter have a shining and nearly downless surface, instead of the rough dull appearance which we meet in those parts in the common Potatoe.”’ Dr. Lindley also emphasizes the absence of tubers and the smoothness of the calyx in a note to his technical diagnosis: “Facies omnino S. twberost, sed tubera nulla profert ; flores majores sunt, brevius pedunculati, calyxque glaber est et lucidus, nec pilis hispidus. Species certo certius distinctissima, etsi notis levibus cognoscenda,’’ Mr. Paton considers that the plant which he has called S. etuberosum in his “ Notes” (p. 53) is possibly a hybrid, since when it is self-fertilized its seedlings show marked variability. My. A. Sutton, F.L.8., V.M.H., has included in his important studies of various wild forms and species of tuber-bearing Solanums* a plant under the same name, which is apparently identical with the one Mr. Paton has employed. He also finds that, when self-fértilized, the seed- lings of this plant vary to the same extraordinary degree, as is seen in the seedlings of the potato of commerce. This trait in the character of the plant, in which it differs from all the other wild forms cultivated by Mr. Sutton, has led him to believe that this “ may probably be the parent form of the cultivated potato of to-day.”’ Mr. Sutton says, “The examples of Solanwm etuberosum which I possess came originally from the Botanic Gardens, Edinburgh, in March 1887, through Mr. Lindsay, and again from the same stock in 1897 from Dr. Bayley Balfour. They produced at first small tubers about the size of walnuts, and the calyces are hispid; in other respects the plants are similar to the type specimen described by Lindley.” t The original source of the plant in the Edinburgh Botanic Gardens * See Jown. R.H.S. vol. xxxiii. pp. xxviii. and xxxvi. and vol. xxxiv. p. xxviii. also Journ. Linn. Soc. vol. xxxviii. p. 446. + Journ. Linn. Soc. xxxviii. p. 449, NOTE ON ‘“SOLANUM ETUBEROSUM.” 57 is not known, but it is thought to have been introduced from a wild source. Some years ago we had tubers from Edinburgh, through the courtesy of Mr. Lindsay, F.R.H.S.; and, as in many other gardens, we found the plant to be quite hardy, but, as Mr. Sutton observes, to produce tubers abundantly (and under garden cultivation much larger than walnuts) and to have a hispid calyx: characters—which are well shown in the excellent plate * which adorns Mr. Sutton’s paper. Thus, in the two characters upon which Dr. Lindley relied to separate his species from S. twberoswm the present plant is like S. tuberosum. It would therefore appear that this plant is not specifically identical with the one Dr. Lindley described, though with which, if with either, of the described species it should be included appears doubtful. lLindley’s plant is probably lost to cultivation, but the type specimen is in the Lindley herbarium at Cambridge. Mr. W. G. Baker considers Lindley’s plant “likely to be a variety of twherosum’’ and notes there is a wild specimen, labelled with the same name in Mr. Reed’s Chilian herbarium, which differs from the “ type by its more hairy leaves and calyx and more pointed calyx teeth.” The Edinburgh plant, except in the characters mentioned above, agrees well with the description of Dr. Lindley’s plant and in addition differs from S. tuberosum by the fruit, which is globose, having small whitish warts upon its surface. [Whether this is always the case is doubtful, since Mr. Sutton = figures a smaller berry without warts.| In addition Mr. Sutton observes that the pollen of S. etwheroswm is always elliptical (a character which Mr. Paton does not confirm), and as this character is common to the undoubtedly wild forms of tuberous Solanums he con- cludes that in this plant we have to deal with a true wild species. The varieties of the cultivated potato produce pollen which varies in shape. Perhaps the greatest interest attaching to the plant lies in the fact that both Mr. Sutton and Mr. Paton have found it, though growing among cultivated potatos attacked by the dreaded Phytophthora infestans, to remain persistently free from the disease induced by that fungus; an observation that we are able to confirm. Since Professor Biffen has shown that, at least in wheat, disease resistance may be an hereditary character, it is to be hoped that by using this form as one of the parents (or grandparents) we may obtain a potato at last which will resist the attacks of the fungus which causes more loss every year to potato growers than any other. = .c.te 46. + ‘“ Tuber-bearing Solanums,” Jowrn.

MANY years ago many varieties of Anemone intermediate between Anemone fulgens and A. stellata were noticed in the gardens of the French Riviera. In this district A. fulgens was then only to be found in gardens; it is admittedly a good species and reproduces itself fairly true from seed. On the other hand, A. stellata was to be found growing wild, especially about Cap Martin; yet this wild anemone is so inconstant in its characters, and so variable in its seed-progeny, that we are compelled to class it rather as a group of varietal forms than as a species in the generally accepted meaning of this word. A few years ago Messrs. Vilmorin, Andrieux & Co., of Paris, put into commerce an alleged hybrid between these species, which, as I understand, they had themselves obtained from a private garden. This is the plant of which I am now treating. Quite recently the same hybrid appears to have arisen spontaneously in the garden of Messrs. van Tubergen, Jun., of Haarlem. In the latter instance the seed parent was a fine form of the species known in gardens as A. fulgens annulata grandiflora, and grew in a collection, amongst which were forms of A. stellata. As a result of sowing the seed of the former there arose an intermediate race differing in no other respect from the hybrid of Messrs. Vilmorin, excepting that it possesses a wider range of colour. This is not at all to be wondered at when we reflect that A. fulgens annulata is a bicolored form of A. fulgens. Now although there is no direct evidence that any particular persons pollinated one species with the other, yet we have the evidence that an intermediate race springs up between these species when they are grown in juxtaposition, and that the origination of this intermediate race has been observed on three different occasions by credible witnesses. I will now show that the alleged hybrid hold a position equipoised between its alleged parents ; beyond this no further evidence can be adduced until an analysis can be made of the subsequent generations springing from the self-fertilized hybrid plants—providing the same are not sterile. On comparing the alleged parents we note only three characters in which they differ iter se, and in only one of these is this divergence very wide. They are as follows :— A. Foliage in male, slightly taller ) Ei had talesar commen a i 3 female 7 shorter B. Sepals ,, male, number 10 to 12 ) Fae Se Oe tes sy Lemale: » 12 or more} - 2 C. Colour in male, white to purple or rosy | lari peneee th C ? , female, intense scarlet j y 2 tie ANEMONE VARIATA. 59 Ce The formula would therefore be Ab or in the individuals I have observed. But I would note that the only divergent character upon which we should place great importance is in the colour of the sepals. In this one respect there is no doubt that A. variata holds an intermediate position ; but the doubt may certainly arise whether two forms of the genus which only differ markedly from each other in the one respect of colour should not be included in one species. On the other hand, as garden plants, A. fulgens and A. stellata are sufficiently distinct, the former being noticeable for the regularity of its intensely coloured sepals, and the latter for the comparative irregularity of its palish sepals and for its richness in albinos and albinoids. The alleged hybrid is generally of an intense purple, and varies between a crimson-purple and a brilliant old-rose colour. Up to the present time I have not seen any other shades of colour. 60 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. COMMONPLACE NOTES. By THE SECRETARY, SUPERINTENDENT, AND EDITorR.

With 150,000 more bunches of Bananas received, the Return shows a reduced gross value of £2,000 compared with 1907, a pronounced reduc- tion in prices. This fruit, and Lemons, show the highest increase in imports, and as both are foreign fruits, the general stability of the other outdoor fruits given in the Return would perhaps indicate that the home orchards are keeping pace with the increasing consumption—a consideration of satisfaction to fruit growers. The importations of Tomatos show a stationary figure for the past eight years, but those of Potatos reached a high level. The value of Fresh Flower imports is lower than the four preceding years by £4,000. This is satisfactory, as the four earlier years had been abnormally high in imports. The exports call for little comment, as the figures show scarcely any or, perhaps, no variation beyond the average. The consumption of Oranges fell short of the previous year (1907), comparing imports and exports, by 364,000 cwt. Imports AND Exports OF Woop AND TIMBER. The amount of unmanufactured timber imported is necessarily very high, though its value in 1908 fell short of the preceding year by nearly £300,000. Again, the value of imported manufactures of wood and timber increased by £50,000, while the value of the exports of this class of goods fell by £151,000. This would make British wood manufactures appear to be in a depressed condition, but comparing 1904 with 1908 we have valued exports of £170,258 and £1,256,545 respectively—a most wonderful comparison. Similarly the exports in 1903 were £179,902, and in 1902, £187,755, so that the advanced export of to-day is really highly satisfactory. BOOK REVIEWS. 63 BOOK REVIEWS. “The Practice of Forestry.”” By Percival Trentham Maw. §8vo., 503 pp. (Walter & Walter, Heatherside, Brockenhurst, Hants, 1909.) 17s. 6d. net. During the last few years a number of books have been written on subjects connected with forestry—the outcome no doubt of the afforesta- tion question. The present work is a valuable addition to those already published, though the high price will no doubt considerably restrict its circulation amongst those for whom it is specially intended. The subjects are very broadly treated and more froma scientific than practical point of view, and include almost all that is necessary for the student of forestry. There is one sentence that we would like to emphasize and that is Mr. Maw’s remark that “ As regards forestry education, I should like to express my opinion that British foresters can only learn their forestry in this country.” No more truthful words were ever expressed, and it is to be hoped that in conjunction with the afforesting of waste lands by the Crown this important fact will be steadily borne in mind. The book is divided into eighteen chapters, some of the most important being “The Financial Aspect of Afforestation,’ ‘‘ Average Yields from Forest Lands,”’ “ Natural Regeneration ’’ and “ As to the Choice of Trees to Plant.” The latter is a sadly neglected point in British forestry, and mainly to this neglect is due the unproductive nature of many of our wood- lands. The ‘‘ Sylvicultural Notes on Timber Trees ”’ contain little that is new, and it is wrong to suppose that the Western Plane (Platanus occt- dentalis) is at all common in this country. Regarding the “ Forest Tables,’ that on quarter-girth measurement i is only an extension of Hopper’s, while basal areas are little required. Altogether the work’ is a valuable one and reflects credit on the compiler. “The Boy’s Own Nature Book.” By W. P. Westell, F.L.8., M.B.0.U. 8vo., 874 pp. (Religious Tract Society, London, 1908.) 3s. 6d. It is rather difficult to decide for what class of readers this book of Mr. Westell’s is intended. From its title one would certainly imagine that it was for boys, but if so, what interest could Chapter II., consisting of 28 pages, be to them? It certainly contains many moral lessons and appears to be intended for their teachers and not for them. Why then insert it? One finds many half-tone figures taken from photo- graphs which could not interest anyone but quite a child, such as a lamb, a mare and her foal, a Jersey cow, evidently taken in a show-yard, a full- faced view, which does not show the points of the animal. Some of the notes in “ Nature’s Year”’ are very trivial, and not worth mentioning. In commenting upon the many strange local names given to some birds, he | says, “ The common partridge probably possesses the most curious name 64 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. of any British species of feathered folk in that of ‘bird.’”’ It is evident that he has not mixed much with shooting men; in old times the name was no doubt given by them to the partridge, which was then the bird par excellence in their estimation, and to this day a sportsman will use the word “ bird’’ when speaking of a partridge. On page 252, in alluding to the grubs of “Ichneumon flies ”’ the following curious expression is used: “Ina word the little mite eats its own environment.” The writer should have said the little grub, so as not to run any risk of being misunderstood ; the word “ environment ”’ is hardly suitable for a boy’s book, and it is generally used with a totally different significance. The author in writing about ichneumon flies is apparently dealing with a matter of which he knows nothing. They are insects belonging to the order Hymenoptera, and like the other members of the order have four wings, and as a rule their bodies are long and slender, and are very unlike the figures given. ‘These figures represent two-winged flies belonging to the order Diptera and presumably to the family Tachinidae, a subdivision of the family Muscidae to which the common bluebottle flies and house flies belong. These flies, as well as the ichneumon flies, lay their eggs in the caterpillars of various insects, and the grubs when hatched devour their hosts in much the same way as the ichneumon grubs do. The figures illustrating this subject are very poor indeed. The author is puzzled because the name of’ bittercress is given to the Lady’s smock, or Cuckoo-flower (Cardamine pratensis), as the leaves have not a bitter flavour. But the term bittercress in various botanical works is applied to all the species belonging to this genus; one of the species is C. amara. On page 288, the common oak galls known as “ marble galls” are said to be “oak apples,’ which are .a very different kind of gall, very much larger, of quite a different consistency, containing a large number of grubs, and not quite spherical as the marble galls are. The author’s views as to the formation of oak galls are not those accepted at the present day ; the cause of the formation of the galls is not the piercing of the tissues of the plant by the gall-fly when laying her eggs, but the action of the grub when it is hatched feeding on the tissues, which appears to cause a more abundant supply of the sap of the plant to that part, resulting in the abnormal growths known as galls. Should the grub die, the growth of the gall ceases, showing that it is the action of the grub which causes the growth. The description of the cause of double apples is altogether incorrect. We do not find in the case of double apples that each has a separate stem as they would have “if the growth of two fruits in close proximity to one another became fused together, thus forming a double fruit.” The explanation of the monstrosity is that two flowers were formed on the same pedicel so that they were in such close proximity that there was a fusion of the two young fruits. In a pocket'in the cover at the end of the book are two folded plates, one of the British butterflies, the other of their caterpillars and those of some moths. These insects are briefly described in two appendices. The figures of the butterflies are fairly good, but some of those of the +P BOOK REVIEWS. 65 caterpillars are regular caricatures. No, indication is -given of the real size of the butterflies, which is a great omission. Unmounted folded plates soon become useless in the hands of an ordinary boy. The book is well printed and profusely illustrated, but many of the plates, in spite of the praise bestowed on them, are very poor, and of very trivial subjects. We cannot altogether congratulate the Religious Tract Society on the publication of this volume, or the author on its com- pilation. “That Rock Garden of Ours.’ By Professor F. HE. Hulme. 8vo., 328 pp. (Fisher Unwin, London, 1909.) 10s. 6d. net. Professor Hulme very wisely does not waste much space in the intro- ductory words of this welcome volume, but quickly plunges into the book itself, which is written in a most practical and interesting style, quite different from many works dealing with horticulture. The whole book is filled from cover to cover with the author’s life experience of plants and their habits, and the many qualities or virtues that plants were sup- posed by our ancestors to possess. A mass of information is given on the conditions most suitable for rock plants. Some curious facts illustrating the distribution of plants are given, as, for instance: A house was pulled down in Whitehall; it had no garden attached, the only open space being a paved stable-yard, which was covered with brick rubbish, mortar, and the like; yet on this unpromising material there sprang up rosebay and thirty-four other flowering plants, besides numerous grasses and bracken. From a ball of clay taken from a partridge’s foot Darwin grew eighty-two plants belonging to six different species. Grass seed was sent to Japan to sow on railway embankments, and with the grass seed were various wild plants; many of these, as the daisy, buttercup, and dandelion, have settled happily in their alien surroundings. However, to return to the rock plants, we are glad to see the author recommending very strongly many plants considered too common for the rockery in these days, particularly ferns and other plants which are found growing naturally on rocks and cliffs, and surely deserve a place on all rockeries. The book is excellently printed, with eight coloured plates and forty-two other illustrations. “The Laying-out and Upkeep of Golf Courses and Putting Greens.” By Martin H. F. Sutton. Obl. 8vo., 46 pp. (Simpkin, Marshall, London, 1908.) 2s. 6d. net. This is one of the most practical publications that we have on the making and care of golf courses. The advice on the drainage, preparation of soils, enriching soils, quantity and selection of the proper seeds to sow on different soils, is exactly the information that many of us want. We were a little surprised to find Mr. Sutton expressing an unfavourable opinion of Poa annua for the formation of turf, our experience being that few if any grasses will stand more wear and tear on a poor soil, but we are in complete accord with him in speaking well of all the grasses he names. Festuca ovina tenumfolia, Poa pratensis, and Festuca duriuscula are all good wearing grasses. The information on the upkeep and improve- ment of greens and the manures to use is valuable. There is no doubt DVOU REX. EF 66 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. that this subject has not been as carefully thought out in many places. as it should have been, and manures have been used that have had the effect of covering the greens with clover. Mr. Sutton says “the applica- tion of farm-yard manure as a top-dressing cannot be tolerated for a moment. It is both offensive and unsightly.” Another reason may be added: it is liable to cause a quantity of noxious weeds to spring up, and result in no end of trouble to eradicate them. A great deal of other valuable advice is given of the mast practical character, that will be most serviceable to golf players, and to those who have lawns. “Studies in Fossil Botany.” By D. H. Scott, M.A., LL.D., F.R.S. Ed. 2. Voli. Pteridophyta. 8vo., 363 pp. (Black, London, 1908.) 6s. net. This work is one which no advanced student of botany or geology can afford to neglect. The first edition of Dr. Scott’s “Studies in Fossil Botany ”’ published in 1904, was based on a course of lectures given at University College, London, in 1896. The matter contained in these lectures was brought up to date in 1904, and the book then published at once took first place among works dealing with Fossil Botany. The style, at once simple and lucid, without being merely “ popular’ in the less reputable sense of that term, made the book one which could be read and enjoyed, as few books can be which deal so thoroughly with any branch of know- ledge. But, as the author stated in 1904, “ happily Fossil Botany is an eminently progressive branch of science and thus the mere lapse of time has necessitated the introduction of much new matter and of many new points of view.’’ This is still more true at the present time. The pro- gress of the science has necessitated remodelling and almost completely rewriting the book. The discoveries of Oliver, Kidston and others, including the author himself, have brought to our notice the great Paleozoic group of fern-like seed-bearing plants the Pteridosperms. Fossils, formerly thought to belong to the ferns proper, have been (metaphorically) ‘ pieced together ” with wonderful skill and industry to form seed-bearing types of the new eroup. But the ferns proper have not been neglected. The ancient synthetic group, the Botryopterideae, have been more fully investigated and must, of necessity, be considered in any scheme dealing with the phylogeny of Pteridophytes. In America Dr. Wieland has published the results of many years’ labour on American fossil Cycads and his discovery of the hermaphrodite strobilus of Cycadoidea ingens has stimulated research and speculation concerning the origin of the Angiosperms. Such discoveries as these could best be described and collated by the author of “Studies in Fossil Botany,” and Dr. Scott has decided to bring out the new edition in two volumes. The first volume, dealing with Pteridophyta, contains less that is new than will be given in Part II.; hence its earlier publication. The chief additions to Part I. include work ‘by Mr. Hickling on Paleostachya and M. Halle’s researches on Mesozoic Equisetales. Dr. Scott’s own work on Sphenophyllum fertile and Prof. Nathorst’s discovery of the Pseudo- borniales are described. The probable connection between the Spheno- phyllales and the Equisetales is clearly and critically discussed as well as the connection between the Psilotaceae and the Sphenophyllaceae. In the . 4 ; 1 i; BOOK REVIEWS. 67 Lycopodiales stress is laid on the development of the “seed habit’’ in plants (Lepidocarpon and Miadesmia) which are remote from the main line of the descent of seed-bearing families. Necessarily, the chapters on Paleozoic ferns have been much altered, descriptions of many “ fern fronds’’ and “fern impressions’’ being transferred to Part II., since many of these fossil ‘‘ ferns’ have now been shown to be Pteridosperms. The ferns proper receive full and accurate treatment; doubtful cases are discussed.and the new work on the Botryopterideae is thoroughly well described and critically considered. The book is admirably illustrated by photographs reproduced from original papers and by clear drawings by Mrs. D. H. Scott and Mr. G. T. Gwilliam. It is a work which will make the reader impatient for Part II., and we trust that in view of the im- portance of recent work on Fossil Spermaphyta the publication of the second volume will not be long delayed. “Trees and Shrubs of the British Isles, Native and Acclimatised.” By C. 8. Cooper, F.R.H.S., and W. Percival Westell, F..5. Part I. 4to., xii + 12 pp. (Dent, London, 1909). 1s. net. Though there is little new in this book, yet the minutely accurate and beautifully executed illustrations—indeed the whole get up of the work —should recommend it to everyone who is interested in the trees and shrubs that have been found suitable for cultivation in this country. The work is to be completed in sixteen parts, and if the succeeding numbers be equal to the first the whole will form a useful book, while the low price will bring it within the reach of all. We are promised chapters on almost every subject bearing on trees and shrubs —soils, planting, insect and fungoid pests, the age of trees, commercial products, plea for an Arbor Day, seed, re-afforestation. Than the coloured picture of the strawberry tree (Arbutws Unedo) which accompanies the first part of the book nothing more accurate or beautiful could be desired. “Our Forests and Woodlands.’ By John Nisbet. New and revised edition. 8vo., 848 pp. (Dent, London, 1909.) 3s. Gd. net. If only for the chapter on “ Ancient and Modern Forestry’’ this book is well worth perusal, and Mr. Nisbet is certainly to be congratulated on the result of his research in that way, fora fuller account of the rise and progress of forestry in this country has not before appeared. We would strongly recommend everyone who has an interest in forestry to read the chapter. Regarding the rest of the book, there is nothing new, the descriptions of our commonly cultivated trees and the uses to which the timbers are applied being old news re-garnished and freshly dished up. The work is pleasantly written, sparsely illustrated, and being cheap will come within the reach of all. 4 The Moths of the British Isles.” By R. South, F.E.S. Second series. 8vo., 8376 pp. (Warne, London, 1908.) 7s. 6d. net. Messrs. Warne have recently published the second series of “The Moths of the British Isles comprising the families Noctwidae to Hepialidae,” F 2 68 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. which under the new classification of these insects also includes the Geometridae, Zygaenidae (or Burnet flies), Cosstdae (Goat moth), Sestidae (Clear wings), so that the three volumes by Mr. South—the Butterflies and the first and second series of Moths—contain figures and descriptions of all the British Lepidoptera except those commonly known as Micro-Lepidoptera (the Yortrices and Tineae). The author in his preface says, speaking of these: “The small fry, as they have been called, exceedingly interesting though they may be to a limited number of students, have therefore been left for separate treatment atsome more con- venient season.”’ All collectors of British Lepidoptera will earnestly hope that Mr. South will soon find this “ more convenient season,” for though the students of the Micro-Lepidoptera may not be so numerous as those who ~ study the more attractive groups, their numbers would soon increase if they had a volume similar to those already published to help them. This volume, like its predecessors, is admirably got up. The coloured plates are excellent; No. 41 is perhaps the least satisfactory, the colours of the moths (the large and small emerald) do not show up well against the tinted background. The black-and-white figures are very clear, but are rather hard and diagrammatic ; the hardness may be accounted for to some extent by the smoothness of the paper on which they are printed; they, however, serve their purpose very well. ‘I'he letterpress gives terse but very clear descriptions of each species both in the perfect and caterpillar states, with some details of their life history and the localities where they may be found. In the preface we read: “ Both classification and nomenclature are always under revision, and we are probably a long way from hearing the last word concerning either; these are, however, matters that cannot be ignored even in a popular work, consequently I have ventured to adopt sundry changes in arrangement, and names although not departing from the old style in any very large way, still approach pretty closely to the new. It would have been of great assistance, however, in this matter if a table had been given showing the classification adopted in this work, which should be in the hands of everyone who collects or is interested in British Lepidoptera. There is no other book which can be said to cover the same ground in such a thoroughly satisfactory manner. ‘“ Beautiful Flowers and How to Grow Them.” By Horace J. Wright and W. P. Wright. Complete in 17 parts (Jack, London, 1908). 1s. each part. We have before us the first nine parts of this work, which is admirably printed and artistically got up. When we state that there are 100 coloured plates by such talented artists as Beatrice Parsons, Eleanor Fortescue Brickdale, Anna Lea-Merritt, Hugh L. Norris, Lilian Stannard, Margaret Waterfield, A. Fairfax Muckley, and Francis I. James, it is at once evident how well they are done. The first part is given up entirely to roses, the second part principally to bulbs, which run well into the third part, and the fourth and fifth parts entirely to herbaceous plants. The sixth part is chiefly devoted to rock plants, of which a capital descriptive list is given, and good cultural hints. Parts 7 and 8 are nearly all taken up with stove and greenhouse plants, the kinds and varieties finding most favour being dealt with in a very practical manner. | - . BOOK REVIEWS. 69 Part 9 is largely devoted to window and room plants, and finishes Vol. I., filling 200 pages. Vol. II. commences in this part, and begins with a chapter on Carnations followed by one on Dahlias. “The Flowers and Gardens of Japan.” Painted by Ella du Cane. Described by Florence du Cane. Sm. 4to., 294 pp. (Black, London, 1908.) 20s. net. In the very first sentence of her preface to “ The Flowers and Gardens of Japan’’ Miss Florence du Cane makes a statement with which it is impossible to agree. She says “An apology is due to the reader for adding this volume to the long list of books already written on Japan.”’ For such an altogether delightful book no apology whatever is needed, but rather the thanks of all flower-lovers are due to the Misses du Cane for giving them a charming book on a fascinating subject. This is nota great book, nor a deep book, nor does it pretend to be a text-book. Readers wishing to study seriously the mysteries of Japanese landscape gardening with all its symbolism and its rigid laws and ceremonies are referred to Mr. Condor’s wonderful “ Landscape Gardening in Japan.” As Condor caters for the student, so the Misses du Cane cater for the dilettante, and give us the flowers and gardens of Japan as seen through European eyes. The illustrations are typicaliy from the European standpoint. The predominant idea in a Japanese garden is form and line and pro- portion. Colour is rather a secondary consideration. Not a word need be said against the form and line and proportion in Miss du Cane’s paintings, but it is evident in practically very one of the fifty drawings reproduced that colour, in a charming setting, but always colour was the main factor which impelled her to paint. This is of course as it should be in a book whose object it is to charm rather than to instruct, to show us the gardens of Japan as we should see them rather than as the Japanese see them. - As examples of ‘“three-colour”’ reproduction from water-colour drawings these illustrations are very fine indeed. Miss du Cane gives a feeling of atmosphere in an extraordinarily clever way. Some of her drawings drag you right out into the open air. The texture and modelling of her rocks and stones are very subtle, and the accuracy, with breadth of treatment, of her flower masses most fresh and satisfying ; yet happily, in reproducing and reducing her paintings for book illustra- tion, these fine qualities have been preserved wonderfully well. Charming as are the paintings illustrating ‘The Flowers and Gardens of Japan,” the letterpress is equally interesting and delightful. A great amount of Japanese garden lore, together with many excellent pieces of descriptive writing, are given. The first chapter deals with Landscape Gardening. Although we may learn much from the Japanese in this art, how futile it seems to attempt a true Japanese garden in England! It is probable that no Englishman would ever make the real thing. FEiven after a life’s study of the subtle technicalities of the art he would lack the Japanese mind, and to his unlearned fellow-countrymen his work would remain a curiosity with some beautiful points and many meaningless accessories. Let us learn from the Japanese, not imitate them parrot-wise. It would be better almost to stick to a good honest circle 70 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. of scarlet, blue and yellow, of geranium, lobelia and calceolaria, than produce some of the hybrid atrocities which have recently been per- petrated in this country under the name of Japanese Gardens. Chapter . II. deals with Stones, Ornaments and Fences, and Chapter III. with Landscape Gardens ; and then follow chapters devoted to Nursery Gardens, Dwarf Trees and Hachi-Niwa, the wonderful miniature landscape gardens representing whole scenes within the space of a shallow dish. The night fairs in Kyoto must be fascinating. Miss du Cane says of them: “On April 1 the best night-market is held. The stalls will be covered with tempting little flowering trees, their buds almost bursting and full of promise of lovely blossoms to come; sturdy little peach trees, their branches thickly covered with soft velvet buds just tinged with pink; drooping cherries wreathed with red-brown buds; slender Pyrus trained into wonderful twisted shapes; little groves of maple trees, their scarlet or bronze leaves just unfurling; or miniature forests of larch, shading mossy ravines with rivers of white sand; ancient pine trees spreading their branches over rocky precipices rising from a bed of pebbles; sweet-scented Daphnes, golden-flowered Forsythias, and early Azaleas in porcelain dishes, which are round or oval, snallow or deep, and of every shade, from white through soft greys and blues to a deep green.” These treasures are to be bought at from a few sen to two or three yen! Then follow an interesting chapter on Temple Gardens, and a delightful one on Summer Flowers. In May Miss du Cane visited Matsushima, the land of the pine clad islands, and later Nikko, to see the Azaleas, a gorgeous feast of colour. Her description of Liliwm auratum in its wild state is worth noting from a cultural point of view. She says: “ By the middle of July the big buds of Liliwm auratum will be fighting their way through the rank growth along the roadside, and in a few days the air will be filled with their scent. Often I was attracted by their fragrance, perhaps all the more remarkable in a land which alas! is not famed for sweet smells, and then far above one’s head, hanging defiantly out of reach, could be seen a single splendid bloom of this king among lilies. They seem to love the shelter and dampness of the wood, where the falling leaves each autumn make a fresh covering for their bulbs. Once I tried to see how deep in the earth the bulbs were buried, but I did not succeed in getting down low enough, and could only tell, from the mark on the stem of the lily which had been pulled, that about 8 or 10 inches seemed to be the usual depth of the bulb.” How often gardeners in England fail to get Lilium auratum to grow, through not planting it deep enough! Other chapters deal with Peach, Plum and Cherry blossom, Wistaria and Paeony, the Iris, the Chrysanthemum, Maple, Pine and Bamboo, &c. “The Flowers and Gardens of Japan ”’ is a book to read as well as to look at, and, as has already been said, no apology for its production is necessary. ‘The Florist’s Bibliography.”’ By C. Harman Payne. 8vo., 80 pp. (Wesley, London, 1908.) 3s. 6d. net. This book has been prepared by a lover of books, and is a useful guide to those forming a library dealing with florists, flowers, and the flower garden. CO a a a BOOK REVIEWS, 71 There is a curious frontispiece which has been copied from an old French work on the auricula published in 1738, evidently taken at a time when auriculas were not in flower, as those represented are caricatures. Mr. Payne is a book collector, a lover of old gardening books, and the preparation of this book has been a labour of love to him. There is one important omission, as the author mentions in the preface, the rose. He says there is “no need to go over the ground again that has been traversed by Sefior Vergara, although a supplement to his ‘ Bibliografia de la Rosa’ might now be reasonably considered desirable.’’ The author has quoted from first editions as far as practicable. The book is useful also in letting us know what we want as well as what we have. There are nine works mentioned dealing with the auricula, but the latest is fifty years cld. The auricula is a more popular flower, and much better grown now than it used to be; as its culture is better understood there is room therefore for a trustworthy treatise on the auricula. Indeed the author of the treatise alluded to has passed away, but he was not a cultivator. The date is 1857. Bulbs and bulb culture have been well dealt with in quite recent years; the latest book is by Mr. John Weathers (‘“ Beautiful Bulbous Plants, 1905’’). There are many old and modern books on the Hyacinth and also on the Lily; and, showing the importance of the Tulip, there are twenty-four books dealing with it, the oldest dated 1654, the newest 1907. The Carnation, Picotee and Pink are credited with forty-eight works beginning with “ Le Jardinage des (Hillets,”’ Paris, 1647, by “ L. B.,” and the latest, also published in Paris, “ Essais sur histoire de quelques fleurs d’ornement: L’(iillets”’ (Le Texnier, 1908). Of course the carnation had been written about in the sixteenth century, although not in the form of a special treatise ; the importance of the Chrysanthemum ‘as a garden favourite is amply demonstrated by the fact that no fewer than 103 books are enumerated and thirty-three society publications. Of course there would be no book on the chrysanthemum earlier than the nineteenth century: the earliest quoted by Mr. Payne was published in Vienna in 1833 by J. B. Rupprecht ; the earliest in England in 1843 by Mr. Tyas. The late Mr. J. Dale, of the Temple Gardens, wrote an excellent treatise which was published in 1856. Modern books are plenti- ful on this subject. Thirty-six books are enumerated dealing with the dahlia, and several society publications. The dahlia seems to have occupied public attention in France earlier than in Britain. Jacquin Fréres published an essay on the cultivation, classification, and nomen- clature of the dahlia as early as 1828, and between that date and 1841 inclusive there were twelve books published in France dealing with it. No one but a lover of books would have taken the trouble involved in searching out and classifying such a large number of books in English, French, and German, treating on every subject connected with the flower garden, and especially with what are termed florist’s flowers. The book should find a place in every garden library. _ “Tittle Gardens, and How to Make the Most of Them.” By H. H. Thomas. 8vo., 152 pp. (Cassell, London, 1908.) 1s. net; cloth Is. 6d. net. A capital little book for the amateur, full of the information he needs, clearly dealing with the making of a garden and all it entails. In the gs 72, JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. next edition we would suggest to the author to add “ Knglish or Broad- leaved ’’ to Paradise stock on p. 143, as this is infinitely superior to the French Paradise stock: the latter should never be used in this country when planting bush or pyramid trained trees. We also think it must have been a printer’s error to place “ Beauty of Bath’’ amongst cooking apples, as this is of no value for cocking, but is one of the best early dessert varieties. With these exceptions we have nothing but praise for the little work. “Garden Rockery : How to Make, Plant, and Manage It.” By Francis George Heath. 8vo., 173 pp. (Routledge, London, 1908.) 1s. To anyone about to construct a rockery this will be a very useful book, as it points out what to do and what to avoid. With many the tendency is to attempt too much, to use too much stone, making the rockery very artificial instead of natural. Again, the way in which stones are placed in the rockery is of vast importance, and here the instructions of the author will be most serviceable, showing by illustration how they should be fixed. There is an excellent list of plants suitable for the rockery, and the whole is well printed and illustrated. “Alpines and Bog Plants.”” By Reginald Farrer. 8vo., 288 pp. (Arnold, London, 1908.) 7s. 6d. net. This may be described as a companion book to “ My Rock Corton being written and printed in the same style. The present volume is sure to be appreciated, as it treats a very popular phase of present-day gardening, and we venture to think a phase that will become still more popular, as many garden-owners are now taking less interest in their glass erections, and developing Alpine, bog, and water gardening to an extent probably never equalled before. From the first chapter on ‘‘ Shrubs and their Placing’ and the second chapter on “Shrubs, mostly Ever- green,’ one may learn valuable lessons, as the author has studied the plants in their native habitat, and tells us under exactly what conditions they seem to thrive best. We are glad Mr. Farrer points out the hardi- ness of so many beautiful shrubs, as many who really love their garden have still little idea of the wealth of hardy shrubs; the beautiful Nandina domestica with its handsome foliage, for instance, so rarely seen, and quite as hardy as the common laurel, but infinitely more beautiful. The same applies to climbing plants; many still plant Wastaria sinensis, and we agree with the author that at her best she is but a poor pallid widow compared with the bridal opulence of Wistaria multiyuga. This is only one example of what Mr. Farrer points out as desirable improvements in our gardens; there are many others quite as good. The other chapters on Alpine plants, large and small Bog plants, Iris, Lilies, the Water Garden, &e., are all admirably written, and in such a clear manner that no one can fail to follow the author and his ideas all through the book. The illustrations are excellent. “The Book of the Pansy, Viola, and Violet.’ By Howard H. Crane. 8vo. 106 pp. (lane, London, 1908.) 2s. 6d. net.. In this book we have an excellent history of the pansy and viola, with exceedingly good chapters on their uses and cultivation, the insect and ee Yee BOOK REVIEWS. 73 fungoid pests that attack them, &c. Only a comparatively short chapter is given to the cultivation of the violet, with another one on the best varieties to grow: Where the violet is attacked by that persistent fungus that causes yellowish brown spots on the foliage, we cannot do better than quote the author’s advice on p. 54: “ Whenever this is seen the affected stem should immediately be removed and destroyed. Do not throw these diseased pieces on the rubbish-heap, but burn them.” Although this advice is given for the disease on pansies and violas, it is equally good for the violet. We regret the author recommends the use of Violas as a groundwork for roses: our experience is most decidedly against it, as the rich food usually given to roses caused rampant growth in the violas, often a foot or more high, making the roses leggy in growth, and we also find a much greater percentage of deaths amongst the roses carpeted with violas than amongst those free from any carpet plant. The viola is so beautiful from early in the year till quite late in the season, that it is indispensable in most gardens, and we thoroughly endorse all that Mr. Crane says in its favour. We can confidently recommend the book to all lovers of these charming flowers, as it is full of sound practical information, that may be followed out easily by anyone. “The Illustrated Strawberry Culturist.”’ By Andrew §. Fuller. 8vo., 59 pp. (Kegan Paul, London, 1908.) 1s. 6d. This book was written for American readers, and scarcely one of the varieties of strawberries named are known in this country ; still there is so much interesting matter and a good deal of useful information in the book, that it is well worth the British grower’s perusal. “Gardens, Past and Present.” By K. L. Davidson. 8vo., 282 pp. (Laurie, London.) 6s. net. We have seldom read a book more pleasantly written or better printed than this. Many gardening books are dry and uninteresting except to the enthusiast, but even the least enthusiastic gardener will read these pages with pleasure and profit. Mr. Davidson tells us how in the far past ages, after the Roman Invasion, Julius Agricola fostered the cultivation of the land so much that, under him and his successors,.Britain became one of the granaries of the world. He traces the history of the formation of physic gardens, and how the cultivation of vegetables was increased and became general through the settling of Flemish cloth-workers in this country. The chapter on “Trees Native and Naturalised’’ is very interesting. Naturally Kew takes the premier place as a Botanic Garden, and the author writes in an enthusiastic strain of its beauties and its practical assistance to the community, while the gardens at Edinburgh, Dublin, and other places receive their fair share of praise. ’ In the second part of the book present gardens are equally admirably dealt with, and most will agree with the author that the question of style should be governed by environment only, and not by any passing fashion of the day. To do away with formality in some of our old gardens would be to ruin them absolutely, yet occasicnally we see this occurring. 74 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. “Bulbs and their Cultivation.” By T. W. Sanders, F.L.8. 8vo., 212 pp. (Collingridge, London, 1908.) 2s. 6d. net. Like all the books written by this author, this work is full of sound practical advice and information, put together in such clear and pleasing style that it gives not only profit but also pleasure to read it. The book is divided into three parts. The first part treats of hardy bulbs of all kinds, soils, manures, bulbs in beds, borders, and on rockeries, the naturalizing of bulbs, liftine and storing, outdoor lilies, bulbs in window boxes, &c., and a useful tabular list of bulbs. The second part is devoted to indoor bulbs, and embraces the cultiva- tion of almost every kind of bulb for the stove, warm or cool greenhouse, frames in water, and in fibre, forcing, &c. The soil, treatment, feeding, and other matters of both great and small importance are well dealt with, and no one can go far wrong in following the instructions. The third part is taken up with the propagation of bulbs and tubers, their English names, pests and diseases, selections of the best varieties, and a most useful glossary of terms. We commend this book to all. ‘The Book of Fern Culture.” By Alfred Hemsley, F.R.H.S. 8vo., 112 pp. (Lane, London, 1908.) 2s. 6d. net. As might be expected from such a well-known plant-grower as Mr. Hemsley, this book is an excellent addition to the multitude of books now published on horticultural subjects. It is a pleasure to see the author advocating a sensible and economic system of growing ferns, 7.e. treating them more like ordinary plants instead of keeping them in an atmosphere heavily charged with moisture. Every phase of fern culture, from the raising of the plants from spores to plants of the largest size, is dealt with ; composts for different kinds and the very important subject of watering are admirably gone into. “Stephens’ Book of the Farm.” Div. Il. By J. Macdonald. 8vo., 280 pp. + many fine plates. (Blackwood, London, 1908.) 10s. 6d. Div. I. of this work was reviewed in the last volume of this,Journal, and the opinion then expressed applies to this book. The subjects dealt with include Rent and Wages; Soils and Soil Improvement; Rotations; Manures and Methods of Application. We consider this work the best of its kind available at the moment, although severe competitors are now appearing. “‘Handbook of Geography, Descriptive and Mathematical.” By Dr. Kimil Reich. 8vo., 2 vols., 568 pp. + 171 pp., 10 coloured maps, and many figs. (Duckworth, London, 1908.) 12s. 6d. net. This work consists of two volumes, the first entitled ‘“ A Descriptive Geography of the World” and the second devoted to Astronomical or Mathematical Geography. The author tells us that “the first part, or Descriptive Geography, treats of the various countries of the five continents, and the chief aim was to enable the reader to form a fair image of each bigger landscape, or, in other words, to view each country, or big sections BOOK REVIEWS. T5 thereof, from a standpoint so high in air as to admit of taking in ata glance entire provinces.’ We cannot say that he has succeeded in his effort, for he does not appear to have worked on any definite plan. Many of his pages contain innumerable short sentences and disjointed expres- sions in note form, making the reading very monotonous and even painful. The opening chapter on the British Isles covers thirteen pages, and deals entirely with physical features, no mention being made of our large towns and industrial centres. In some other chapters the method is reversed, for we find descriptions of towns but much less physical geography. India is treated in this way, and this forms one of the most interesting chapters, but the great range of the Himalayas is practically ignored. The description of the United States of America covers forty-two pages, and contains much useful information, but the vast Dominion of Canada is dismissed in six pages. The admirable set of maps would have better served their purpose had they been accompanied by some explanation in the text. The feeling of disappointment with which one closes the first volume is speedily dissipated on opening the second, and one soon finds that here the author has succeeded in producing a book which should prove of the ereatest use to both teachers and students. “Ruskin Nature Reader.” Senior Book. Small 8vo., 236 pp., 20 illustrations. (Dent, London, 1908.) 1s. 6d. net. This is described as “a collection of literary extracts to accompany a course of Nature Study; selected and edited by G. R. Bennett, B.Sc. (London).”” Of the many so-called Nature Readers which have been pro- duced in the last few years this is one of the most readable. An effort has been made to show “ how Nature has appealed to men, and how men have expressed the influence which the observation of Nature has had upon their thoughts and their actions.” How successfully this effort has been achieved is evident from even a cursory glance through the selected passages. We say a cursory glance, but we doubt whether any sensible scholar opening these pages will be satisfied till he has perused them all, and at the close he cannot but feel that he has been abroad with Dame Nature indeed. The Editor has drawn largely on the friend of our youth, Gilbert White’s “ Nitural History of Selborne,” and has given us six charming extracts dealing with bird-life. The language is, of course, somewhat quaint, having an old-world ring aboutit, a certain charm of its own ; but we would suggest that it might be worth while to conform to modern usages and modify such expressions as “an hundred pieces’’ (p. 18), ‘an hawk appears’’ (p. 36), “an hot stifled inn-yard (p. 41), &. We also note a slight typographical error on p. 385. Gilbert White certainly did not write “the motion of the mandibles are too quick for the eye.”’ The choice of selections has been admirable, and we can heartily join with the Hditor in his wish that, having been given a glimpse of the emotions and expressions of such men as John Ruskin, Professor Tyndall, Richard Jeffries, Louis Stevenson and Sir Martin Conway, boys and girls may be helped “ to observe for themselves the things around them, and also to read and enjoy the beautiful thoughts of others concerning them.” ‘The 76 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY, illustrations are good, but we should like to see a note made of the page to which each applies. “Nature Study.’ By Professor Ainsworth Davis. Crown 8vo., 274 pp., over 100 photographic illustrations. (Dent, London, 1908.) 2s. 6d. This is a Reader for the higher classes of schools, and attempts ‘to give in simple, non-technical language a connected sketch of the natural history of plants and animals.’’ The book is divided into two parts, the first dealing with Botany and the second with Zoology. The botanical section is treated on the ecological plan, and the author has succeeded in producing a very readable introduction to plant study. The scholar is encouraged to carry out simple experiments, make careful observations, and draw conclusions as to how the details of form and structure have a definite meaning in relation to mode of life. There are two excellent chapters on the Struggle for Existence among Plants. A general survey is taken of our more common plants, and details of special interest pointed out. The second part of the book deals mainly with the classification of animals, and, although useful in its way, can scarcely be said to follow out the admirable plan of the botanical section. The author attempts to cover practically the whole of the animal kingdom, with the result that whole groups of animals have to be dismissed in a paragraph, and one has but little chance of making those observations which are supposed to be an essential feature of the new method of teaching. On p. 70 we are told that ‘Begonia plants can be grown from a leaf, which develops roots and buds when placed in damp soil.’’ This statement goes scarcely far enough, and might mislead a young reader. Reference might have been made to the method of insertion, and to the incisions usually made across the principal veins. The latter part of paragraph 425 (p. 151) seems scarcely grammatical, where it says: “The lamprey group (Cyclostomata) is an eel-shaped relative of the fishes, which has not yet developed a lower jaw, and uses its round mouth as a sucker.” The illustrations are some of the best that we have seen employed for the embellishment of a school-reader, and we have no hesitation in saying that on the whole this is an excellent help to nature study in the schools. ‘‘Hiversley Gardens and Others.” By Rose G. Kingsley. 8vo., 280 pp. (Allen, London, 1907.) 6s. net. A well-printed and well-written book dealing with the making of a garden, soils, planting, pruning, spring gardens, bulbs, summer gardens, the rose garden, cut flowers, &c. The illustrations are very good, and a great deal of most useful information is given on the best methods of treating plants individually and collectively, showing a keen observing power on the part of the authoress. It is a handsome book, and will be highly appreciated by garden-lovers. ‘“ Holly, Yew, and Box, with Chapters on other Evergreens.”’ By W. Dallimore. 8yo., 284 pp., 175 illustrations. (Lane, London, 1908.) 7s. 6d. net. We must congratulate Mr. Dallimore on this carefully written and admirably printed book. Such a practical work could only be compiled BOOK REVIEWS. Lev by one thoroughly conversant with the many varieties of the plants he deals with. Mr. Dallimore’s position as foreman of the Arboretum at the Royal Gardens, Kew, has given him unique opportunities for studying the peculiarities of all the varieties under his charge. Very valuable information is given on the habits of varieties of holly, yew, and box, and cultural descriptions are treated in a masterly manner. It is scarcely necessary to state that the work is well up to date, as proved by the inclusion of varieties new to this country from China, collected by Mr. E. H. Wilson for Messrs. J. Veitch. Many old and rare varieties are described, making the work one of special interest to tree and shrub lovers. A small portion at the end of the book is devoted to the evergreen oak, the laurel, and other evergreens, all as much worthy of the reader’s attention as the other parts of the work. We predict this will be considered the standard book on the holly, yew, and box. The index is excellent. : “The Care of Natural Monuments with special reference to Great Britain and Germany.” By H. Conwentz, Prussian State Commissioner for the Care of Natural Monuments. With ten illustrations. 8vo., pp. xii. and 185. (Cambridge University Press, 1909.) 2s. 6d. net. We are not sure that the term “ natural monument,’ the German Naturdenkmal, is either self-explanatory or otherwise satisfactory, though we cannot suggest anything better. Professor Conwentz makes out a good case for his neologism. Not only can he urge that standard works are styled monuments of literature, and that lake-dwellings, which were certainly never “ established in commemoration ”’ of any body or event, are termed prehistoric monuments ; but that Humboldt long ago spoke of big trees as monuments de la nature. This modest but usefully comprehensive little volume, which originated in a lecture delivered by the author at the Leicester (1907) meeting of the British Association, practically begins with a classification of the natural monuments in danger. It then deals with the means of preservation and the extent to which these are realized in the various countries of the world, concluding with suggestions for the future. Professor Conwentz groups the monuments of which he treats under seven heads; views, water (especially falls), rocks, such as the Cheddar gorge, the Marlborough Sarsen stones, or erratic boulders, fens, woods, plants, and animals. The three aims to which preservative efforts should be directed are, he says, an inventory and map, actual preservation 7 loco, and the publication of accounts of these monuments. As to thé means adopted in various countries to realize these ideals, we have government surveys and maps, voluntary associations for similar purposes, such as our Central Committee for the Survey and Study of British Vegetation, and the work of individuals, such as Hewett Watson. Secondly we have national reservations; a state office, such as that in Prussia of which Herr Conwentz is the head; areas protected by public corporations, such as the London County Council, which controls not only public parks, but also open spaces such as Riddlesdown, and the Corporation of London, with Epping Forest and Burnham Beeches; and voluntary bodies such as our excellent National Trust. There is actual legislation such as our Wild “78 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. Birds’ Protection Acts, the laws protecting rare plants in Switzerland, and the international agreement of 1900 as to big game in Africa. There are the numerous private societies for influencing public opinion, such as the Audubon Societies in America, our Selborne Society, the Swiss ‘‘ Associa- tion pour la protection des plantes’’ and the Belgian “Société pour la protection des sites’’; and there are the now numerous county photo- graphic surveys, which, by the by, our author seems to have overlooked. Professor Conwentz rightly dwells or the great amount already done in this matter by private effort, especially in the United Kingdom, as for example the many handsome presents made to the nation through the National Trust. Weare therefore not surprised to find him, although himself the head of a state department, deprecating government action in this matter in Britain. If we do not altogether agree with this conclusion, we none the less feel deeply indebted to the enthusiasm, the industry and the ability of the learned professor for this useful compendium, written, as it is, in faultless English, and concluding complimentarily with Shake- speare’s question, ‘ Who is here so vile that will not love his country.’ “ Experimental Morphology.” By Dr. C. B. Davenport. 8vo., 509 pp. (Macmillan, London, 1908.) 15s. net. The study of the different forms assumed by plants and animals early attracted great attention ; later, the manner of development of these forms was studied; and now attention is being more and more directed towards inquiries into the reasons why organisms develop as they do and what the forces are which direct the path development shall follow. This study of experimental morphology is comparatively new and very much remains yet to be done. The primary aim of the book under review is to give an account of what is known at present concerning the subject in such a manner “as to indicate the directions for further research.” Each chapter contains an account of the action of different external conditions upon protoplasm itself or upon that peculiar phenomenon exhibited by protoplasm called growth, and concludes with a list of the principal papers , already published dealing with the particular branch of the subject of which it treats. The book abounds with details of experiments upon such : subjects as the effect of chemical agents upon protoplasm and upon erowth, and the effects of water, density, contact, gravity, electricity and so on, considered in relation to the living stuff itself and in relation to erowth. A large proportion of the experiments relate to animals, but all the principal effects upon plants are touched upon. This edition appears to be an issue of the original two volumes in one but otherwise unchanged. None of the research of the last twelve years is therefore included. It is to be hoped, for the sake of workers now in the field, that a new edition will soon be called for, when the author may increase the indebtedness of fellow-workers to him by bringing his book down to date. “ British Mosses.”’ By the Right Hon. Sir Edward Fry, G.C.B. 2nd ed. 8vo., 72 pp. (Witherby, London, 1908.) 1s. 6d. net. To those who desire to gain an insight into the structure of mosses and the work they do in the world, this little book can be heartily BOOK REVIEWS. 79 recommended, and none who reads it can fail to have his interest awakened by the lucid account of the mosses, “ the first mercy of the earth,’ which | it contains. The book is abundantly illustrated and the figures in this second edition are a great improvement upon those of its predecessor. ‘‘ An Introduction to Geology.’”’ By Prof. W. B. Scott. 2nd. ed. 8vo., 816 pp. (Macmillan, New York, 1907.) 11s. net. The second edition of this well-known text-book has been thoroughly revised and brought up to date, several of the illustrations, for instance, showing phenomenadue to the great San Francisco earthquake of 1906. The plan of the book is to describe first the principal rock-forming minerals ; secondly to consider the various forces that have been at work in moulding the crust of the earth, dealing with volcanic agencies and the work of earthquakes, and with those surface changes which will more closely appeal to the garden designer, due to the action of water in its different forms ; thirdly, the structure of the rocks themselves is dealt with; then the form of the earth, its mountains and river basins, and so on; finally, an account of the sequence of events in geological time with descriptions of the fossils found in the different strata. The book is written in an interesting style, and profusely and admirably illustrated. The illustra- tions of geological phenomena are taken from many parts of the earth, though as a book written in America for American students, the majority illustrate parts of the United States. A full index is appended. “Tite Histories of Familiar Plants.” By J.J. Ward. 8vo., 204 pp. (Cassell, London, 1908.) 6s. This is one of the now numerous books upon our native flowering plants, written with the object of interesting the unscientific observer in the common plants of field and forest. It deals in a popular way with the structure of the plants treated upon, and especially with their relation to their environment both animate and inanimate. In endeavouring to find an explanation of the form, arrangement and markings of different parts of plants, the author makes many ingenious suggestions, not all of them very convincing. It is a pity, too, to write as though the plants were sentient beings and are even able to convey messages to others of the species; as when, for instance, the first Oxalis found by folding its leaves at night it lost less heat (the suggestion the author makes as the result of the habit), “it forthwith conveyed the hint to the race.’’ This is only one instance of many that occur. The author ascribes sensitiveness to the root-cap—a structure com- posed of dead cells! (page 68). He says, too, that the cowslip is a plant of the low meadows, but surely it is also a plant of the hills; the slopes of the Pegsden Hills, for instance, are covered with cowslips, and so is many a railway embankment. His explanation of the difference in habit of flowering between the cowslip and the primrose seems of very doubtful value. | So long as the reader of books of this kind will exercise his critical faculties and will make observations as to the truth of statements for him- self no great harm is done, but where children are concerned there is often a danger of imbibing theories as facts and finding it difficult later to correct 80 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. them, so fixed do they become on the young mind. One could wish some- times that authors would realize the impressiveness for many minds that still clings round the printed word, and would therefore, in their popular writings, be chary of advancing theories without carefully testing them from many points of view. The illustrations, numbering 120, form a feature of the book and are good photographs well reproduced in half-tone. Most cf them are worthy of praise, though figure 84 does not show the blotches on the Orchis leaves, which itis said to depict. Figure 93 appears to represent Sedwm spectabile, not S. Telephiuwm, as the name is given in the text. “The Methods and Scope of Genetics.”” By W.. Bateson, M.A,, F.R.S. 8vo., 49 pp. (University Press, Cambridge, 1908.) 1s. 6d. net. It was a happy idea of Professor Bateson to publish, for the benefit of the general public, the lecture which he delivered before the members of the University of Cambridge on the occasion of his inauguration as Professor of Biology in October last. The purpose of the lecture is to describe, in a popular manner, the present outlook over the field of experimental research in the physiology of heredity and variation, a study which, owing to Mendel’s wonderful discovery, has now developed into the definite and distinct science known as Genetics. As the author says, Mendelian discovery is leading us into a new world, the very existence of which was unsuspected before. He begins by pointing out the simple fact that each individual plant and animal has a double nature owing to its origin from two cells, one maternal and the other paternal. It is curious that the full consequences of this double nature seem to have struck nobody before Mendel. As Professor Bateson says: “In order to understand the significance cf Mendelism, we must get thoroughly familiar with the fact that a man, a butterfly, and an apple-tree are not each one thing, but are each two things, double throughout every part of their composition. Consequently the contribution of the inaternal and paternal gametes, or ‘ marrying’ cells, may, in respect of any of the ingredients, be either the same or different. If they are the same the regulating organism is pure-bred for that ingredient ; if different it is cross-bred.”’ Recent genetic research has led us to the further important conception that the individual is composed of what we call “ presences’”’ and “absences ’’ of all the possible ingredients. This fruitful conception is the basis of all progress in genetic analysis. As to the nature of these ingredients or factors we at present know nothing, but it is interesting to note that Professor Bateson thinks that with the assistance of the physio- logical chemist, it cannot be very long before we know what some of these factors are. « Professor Bateson next deals with the phenomenon of segregation, and shows that where an individual is cross-bred for a certain ingredient, the germ-cells formed by such an individual alternately either contain or do not contain representatives of that ingredient. In Professor Bateson’s own words: ‘If both the parent-gametes brought a certain quality in, then all the daughter-gametes have it. If it came infrom one side and not from the other, then on, an average, in half the resulting gametes it will ee eee BOOK REVIEWS. 81 be present and from half it will be absent. This last phenomenon, which is called segregation, constitutes the essence of Mendel’s dis- covery.” Professor Bateson modestly shows, in passing, how a little experiment of his with Sweet Peas clearly demonstrated the true nature of reversion and variation. Two well-crown dwarf races of Sweet Peas which breed true, the prostrate ‘Cupid’ and the half-dwarf ‘Bush,’ crossed together produced the ordinary ‘Tall’ Sweet Pea of full height. ‘“ The reversion occurs because the two factors that made the height of the old Sweet Pea again come together after being parted; and the variations by which each of the dwarfs came into existence must have taken place by the dropping out of one of these elements or of the other.’’ Here it may be said that if the study of genetics had done nothing more than this, it would have fully justified its existence, after the many years of vague and futile discussions about reversion and variation since the time of Darwin. It is refreshing to find that a simple experiment with Sweet Peas in Mr. Bateson’s garden at Grantchester should help to give us the solution of two profound problems which have exercised the greatest minds in all ages. In justice to Professor Bateson it seems only fair to point out that though in his writings he modestly ascribes all his results to the work of Mendel, those of us who have had the good fortune to work with him know full well that there is much more than this behind it all. Mendel’s work with culinary peas has undoubtedly been the basis of all recent genetic research, but had it not been for Professor Bateson’s guiding hand, would the problems of reversion and variation have ever been solved? I think not. Other interesting advances are noted in Professor Bateson’s lecture, such as the presence of preventive factors, of superposed factors, of mutual repulsions and interactions between different factors, to say nothing of some stimulating suggestions .on the probable Mendelian inheritance of sex in insects, birds and man. Last, but not least in importance, Professor Bateson alludes to the value of genetic inquiry to the study of evolution and to practical human affairs, and throws out some broad hints to those who are concerned with the problems of the origin of species and the betterment of the human race. In short this admirable and indispensable little book, written by a master-hand, is essentially a popular work in the truest sense of the word, and must appeal to all sorts and conditions of readers, in spite of its some- what technical title. It is a book which makes for progress, and a careful study of it is an absolute necessity to those who wish to be up-to-date in the new science. Through Southern Mexico: being an Account of the Travels of a Naturalist.” By Dr. Hans Gadow. 8vo., 527 pp., 165 illustrations and maps. (Witherby, London, 1908). 18s. net. This is an interesting record of the author’s travels and exploration during some eight months in 1902 and 1904. There are plenty of travel incidents and adventures, which give a very clear and vivid idea of a country which is not often visited by English travellers. The special VOL. XXXV. G 82 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. value of the book lies perhaps in the many details about the life and customs of frogs, tree-frogs, snakes, lizards, and the like, of which a great number were collected. There is, in particular, a very full history of the classical axolotl. There is also a chapter on the ancient civilization in Mexico and its origin, which contains full details of the astronomy and calendars of the Aztecs or Toltecs. The customs and characteristics of the modern Indian inhabitants are often mentioned incidentally. For botanical readers there is a full account of the cultivation of Agave americana, and of its use as pulque; such fruits as the Mexican banana, pineapple, alligator pear, mammee apple and the like, are fully described. The forests of Mexico are still by no means so thoroughly known as one would expect, and there are graphic sketches in many parts of the volume which are of interest. The rain forest is fringed on its outskirts by an impenetrable wall of luxuriant herbage, shrubs and creepers, the tout ensemble recalling a lavishly arranged bank of flowers ata flower show. After hacking and slashing a path through the tangled growth, “we are in a gloomy, stuffy forest consisting of tall straight trees, which branch out at a great height above us, there interlacing and forming a dense canopy of green through which passes little or no sunlight.” ‘From below the leaves, branches, and even bright coloured birds look black.”’ “Tf by a lucky chance, we obtain a bird’s-eye view from some eminence we behold a different world. A dense green carpet overstrewn with thousands of mauve, pink, yellow, or white flowers of some kind ot Bignonia, visited by countless butterflies which are preyed upon by lizards and tree-frogs, these being in their turn sought after by tree-snakes. Of bird life, gorgeous and beautiful in colour, there is plenty. Vividly coloured are also many of the other creatures—frogs, snakes, lizards, and butterflies. Colour has to be laid on vividly, quiet coloration being out of place. This colour-contrast was started by the blossoms, red, yellow, or white; self colours not variegated predominate and stand out very effectively against the green.” The very clear description of the Mexican forest does not, however, apply to all tropical forests, which may be exceedingly different even in one and the same district. The author has also some very interesting notes as to the distribution of plants in the Nevado in which he appreciates the great importance of the cloud zone. There are also many other interesting observations on ants, birds, the Mexican slug, and other animals. “Notes of a Botanist on the Amazon and Andes.” By Richard Spruce, Ph.D. Edited by Alfred Russel Wallace, O.M., F.R.S. 8vo., 2 vols., 518+542 pp. 71 illustrations, 7 maps. (Macmillan, London. 1908.) 21s. net. These notes form a rather miscellaneous collection made from note- books, journals and private letters during Spruce’s long residence in South America from 1849-1864. But they also include several valuable Papers which were prepaved by him for publication and which are to be found in the second volume. BOOK REVIEWS. 83 Many of his adventures and experiences are most interesting, for he travelled in many dangerous and out-of-the-way places, and describes, with almost photographic accuracy, the ferocious insects, the flora, the particularly exasperating Indians and other inhabitants. The scattered references to Orchids, Palms, Ferns, Bromeliads, Melastomaceae and other interesting flowers and trees are often valuable. He was an enthusiastic collector in a botanist’s paradise and tcok every advantage of his opportunities. We must allude also to the full account of the rubber trees, and of the methods of preparation and collection, as well as to his painful and dangerous search for Cinchona seedlings and the successful transport of these specimens from their original home to the seaport from which they eventually reached British India, where their descendants are now flourishing. There are valuable accounts also of the narcotics and stimulants in common use amongst the Indians. His sketch of the vegetation of the Amazon valley is exceedingly clear and compares favourably even with the recent descriptions of Dr. Ula. Indeed one is often apt to forget that these notes are forty years old, and one cannot help wishing that he had worked out several problems of which he evidently knew a great deal more than can be deduced from his rough notes. The floating-islands of the Amazons, composed of grasses which are sometimes forty-five feet long, seem to resemble similar vegetations from the Nile and the Ganges. He has much of: great interest to say also on the different forests in the Amazon’s valley, which are very clearly distinguished and described. There are all sorts of questions connected with anthropology, zoology, geology and meteorology, which are discussed in this work. There is, ¢.¢., a very full history of the Warrior-women or Amazons, of Valverde’s still secret treasure-store, and of the picture writing of the Indians which is found etched on rocks at many points in the valley. But the most interesting part of the volume refers to those ferocious ants which occupy, or perhaps we should say which dominate, the forests of Hylaea. Spruce does not exactly say that they form the ant-gardens by carrying seeds and earth to the forks of the branches, but he alludes to them and very likely did not care to set down what he thought. ‘The Paper on ant-agency, which was written in 1869 and is now published for the first time, is, however, of the greatest scientific importance, and it should be carefully studied by every naturalist. There is a certain Melastomaceous genus, T’ococa, of which there are twenty-four or twenty-five species in the Amazons. One or two of these are entirely submerged in the annual inundations, and these have no ant- homes, but all the others, none of which are ever completely covered by the water, possess peculiar sac-like swellings between the vein-forkings. These are inhabited by ferocious ants which form an efficient bodyguard to the plant. So far as these observations go, they simply add to the already long list of ant-guarded plants. But Spruce in his original Paper states that he examined half-grown plants, and saw that the sacs begin to form long before any ants touch them and proceeds to draw the important conclusion that these swellings or sacs are inherited and are the result of long continued generations of ant-visitors. G2 84 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. It is a case very similar to the well-known acarodomatia or mite-homes common in the vein-forkings of the leaves of many British trees. With _ regard to these it has also been stated that they appear in a rudimentary state before the mites reach them. Readers of this Journal will also recall Professor Henslow’s well-known theory that flower nectaries owe their origin to the probing and tearing of insects seeking pollen or honey. Unfortunately for Spruce, and also for science, it was then supposed that acquired characters could never be inherited, especially if they were of the nature of mutilations. In consequence, this valuable Paper has been held back for forty years, and it is very likely that Spruce was so discouraged by its reception that he did not work out other interesting points. Dr. Wallace, so far as one can see, believes Spruce’s observations to be correct, though without committing himself to the unpopular and heterodox view that acquired characters can be inherited. The Paper may be taken as a valuable step in advance, for there are many instances, not only that of Zococa, of ant-agency. But it is difficult not to feel disheartened and discouraged when one finds that orthodoxy in scientific matters still has such power to discredit and delay the obvious deductions of an experienced naturalist. The publication of this valuable Paper in its original form should make this book necessary for the library of all interested in Darwinism. “ Klementary Botany.” By HK. Drabble, D.Sc, F.L.8. 8vo., 2384 pp. 76 figures. (Edward Arnold, London, 1908.) 2s. 6d. This small text-book of elementary botany has been written for those preparing for examinations requiring but an elementary knowledge of the science, a broad general idea of the fundamental principles in the life of flowering plants, without entering into the minute histological details which entail the use of a microscope. ‘The first 180 pages are devoted to these principles and a simple description of the modifications of the organs of plants, and the student is encouraged to conduct experiments with simple apparatus, taking nothing for granted, but demonstrating for himself the truth of all assertions laid down. About thirty pages are given to a general outline of classification, a summary being given of the broader characteristics of the more important genera in those natural orders which are usually included in an elementary syllabus. The numerous figures are of a somewhat simple character, but sufficiently serve their purpose for illustrating the text. This will prove a very useful little book to put into the hands of a beginner in the study of Botany. , “Roses and Rose Growing.’ By Rose G. Kingsley. 8vo., 163 pp. (Whittaker, London, 1908.) 6s. net. Notwithstanding the number of books dealing with Roses and Rose culture which have appeared in recent years, the present volume fills quite a distinct place of its own. For it is written by an amateur of considerable experience, in the interest of that numerous class of Rose growers who, like the writer herself, tend their Roses themselves, and to whom the exhibition tent offers no attractions whatever. Then BOOK REVIEWS. 85 again, the directions and descriptions are so clearly and graphically given, and with such enthusiasm, that they cannot fail to interest those who have as yet given but little attention to the subjects of which they treat. The early chapters are devoted to such cultural questions as planting, pruning, propagating, &c., while the greater part of the work deals in an interesting manner with the various classes into which cultivated Roses are divided, and the purposes for which they are best adapted—with lists appended of the principal varieties in each. At the end is a short chapter by the Rey. F’. Page-Roberts, President of the National Rose Society, himself an experienced exhibitor, on how to grow Roses for exhibition. In no other part of the volume, however, is the question of Rose-growing treated in any but from a garden point of view. No notice of this Rose book would be complete without special mention of the illustrations, and more particularly the coloured portraits of Roses, which are among the most faithful and pleasing that have yet appeared. “The Nature of Enzyme Action.” By W. M. Bayliss, D.Sc. F.B.S. 8vo., 90 pp. (Longmans, London, 1908.) 3s. net. A highly technical monograph on a section of Biochemistry. It is based upon lectures given at various times in University College, London. The general properties more or less common to enzymes are discussed in such a manner that only the earnest and somewhat advanced student can sufficiently appreciate. A long list of literature which has more or less direct bearing on the subject, and which is to some extent referred to in the text, is given at the end. There is also a good index. “Soils and Fertilizers.” By H.Snyder. 8rded. 350 pp. (Macmillan, New York and London, 1908.) 5s. net. A very useful book by a well-known and painstaking author. Beginning with the physical properties of soils, it proceeds to deal with their formation, classification and chemical composition. Soil nitrogen takes up some forty pages. Organic manures and the various fertilizers are dealt with in a style which most readers will duly appreciate. Food requirements and rotation of crops receive careful attention. ‘Tillage operations are enlarged upon in a manner which shows a master’s hand, and the reader will probably wish this section was more detailed. The work contains a chapter on Laboratory practice. “The Soil: an Introduction to the Scientific Study of the growth of crops.’ By A.D.Hall,M.A. 2nded. 3811pp. (Murray, London, 1908.) os. net. A second edition of a well-known book, and one recommended by the R.H.S. for students. There are several additions and alterations in this edition. The author states he has greatly modified the views he expressed in the first edition on the nature of clay and on the part played by zeolitic silicates in the retention of ammonium and other salts by the soil. He draws attention to the great additions made to our knowledge of the work of bacteria in the soil and the information has accordingly been brought much more up-to-date in this respect. 86 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. The author writes as a scientist and as a teacher, and he is both these of the first water, but he falls into one very serious error. He writes: “There is every probability that the individual farmer will be as often misled as guided by the results of his own experiments. The design and conduct of field experiments must be left to the expert.’’ He will find few to agree with him. | “The Standard Cyclopedia of Modern Agriculture and Rural Keonomy.’ By many Authors; edited by Professor R. Patrick Wright. 8vo., vols I. and II. each 240 pp. and many plates and figures. (The Gresham Publishing Company, London, 1908.) 8s. net each vol. This work, which is to be completed in 12 vols., aims at being an exhaustive treatise on all that appertains to Agriculture, including Horticulture. The contributors are for the most part the best recognized authorities on the subjects dealt with, It would be a bold critic who could venture to question the soundness of the majority of the articles, although before the publication of the entire work is completed we doubt not some of the statements will have been proved to be exploded errors. Vol. I. contains a very valuable anatomical model of the cow. The subjects dealt with are so diverse that without an index it is difficult to find what one requires. Even then the matter is much broken up, probably necessarily so for alphabetical arrangement. The value of the work will very greatly depend upon the index. ‘Gardens of England.” Painted by Beatrice Parsons, and described by E. T. Cook. 8vo., 199 pp. (Black, London, 1908.) 7s. 6d. A charmingly written and beautifully printed and illustrated book which we think would be of more value if an index were appended. About twenty garden scenes are well illustrated in colours, and as in many places similar effects could easily be produced, this work will commend itself to owners of large gardens who may be contemplating alterations or improvements, or making new gardens. The descriptive matter relating to the illustrations contains a mass of information on how and when to plant the various plants figured, and many excellent suggestions are given on desirable plants to grow. ‘“Hnglish Houses and Gardens in the seventeenth and eighteenth centuries.’ Reproduced from contemporory engravings by Kip, Badeslade, Harris, and others. Obl. 4to., 36 pp. 61 plates. (Batsford, London, 1908.) 15s. net. This is not only a most interesting book, but its quaint plates are very instructive in showing the strictly formal style of gardening in vogue during the period mentioned in the title. There are sixty-one plates showing many well-known noblemen’s and gentlemen’s seats: few if any of them would be recognized at the present day. A more natural and beautiful type of gardening has replaced the original stiff plans, but in some of the places mentioned and illustrated that we have visited, there are still the magnificent avenues planted in those days, giving an appearance which excites the envy and admiration of all who do not possess such a noble feature on their own estates. Almost all the build- te z- BOOK REVIEWS. 87 ings and gardens depicted in the plates were made between the years 1550 and 1720; symmetry of design being the prevailing feature of the house, buildings and gardens, and one cannot fail to admire the exceeding care to have everything exactly balanced. Clipped hedges, parterres with box edging, and bowling greens, are much in evidence in some of the engravings, and terraces are seen in almost all, proving that expense was not spared. The book is of a convenient size, well-printed, pleasingly bound. The pages are not all numbered, but the plates are, and are easily found. ! “Mushrooms. How to grow them.’ By William Falconer. 8vo., 169 pp. (Kegan Paul, London, 1907.) 5s. _ Although this work was written in America for American readers principally, there is much that is of interest and value to European readers, in fact, many extracts are from books and papers published in Britain on mushroom culture. While endorsing nearly all the information and advice so ably put before us, we must disagree with the author when he says ‘‘that the manure from carrot-fed horses is good, and anyone having plenty of it can also have plenty of mushrooms.” He freely admits that it is not so good as manure from horses not root fed; and our experience, and that of many others who have grown mushrooms, is that no satis- factory crop of mushrooms can be grown from manure where the horses are daily supplied with roots or where they are physicked to keep them in condition. With the above exception we cordially agree with all the practical author has written, and can recommend the book to all interested in mushroom cultivation. The work is well printed, nicely illustrated, and well-bound. “Children and Gardens.” By Gertrude Jekyll. 8vo. 110 pp. (Country Life, London, 1908.) 6s. net. A charmingly written book with beautiful illustrations, and with the innumerable books on gardening there is still room for this. Nothing is better for children than gardening, and the authoress tells how the love of gardening may be fostered amongst children from her own experience. Many children have been given pieces of barren or rough ground to make a garden, and the work has become so irksome that in a short time they have detested it, and cared very little about a garden ever after, but given a nice little garden already made, the conditions are totally different. All this and much more is fully treated upon by the author, and is well worth reading by all who have children and a garden. The only thing we object to in the book is the praise accorded to cats in the garden; they are nearly as bad as the proverbial bull in a china shop, doing almost as much damage. 88 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. BRUSSELS SPROUTS AT WISLEY, 1908-09. TuHirtTy-Two stocks of Brussels Sprouts were received for trial, all of which, except those received late, were sown on March 21. When large enough the plants were put out at 8 feet apart each way, on land that had been deeply dug and moderately manured. All germinated well, and made excellent growth, but the very hot weather in October caused nearly all the “buttons’’ to become open and loose. Mild weather generally continued to the end of December 1908, when severe weather suddenly set in, the thermometer falling to zero, practically destroying the whole crop. List oF VARIETIES.* 1.

THE Royal Horticultural Society’s fourth Kxamination of the Employees in Public Parks was held on January 11, 1909. As previously, the Examination was partly viva voce and partly written, occupying three hours and twenty minutes. It was held at the Society’s Hall in Vincent Square, Westminster. One hundred and nineteen candidates entered, and of these twenty- five secured places in the first class, forty in the second, and thirty-seven in the third, leaving seventeen candidates who failed to obtain the minimum marks required. No one candidate stands out prominently before the others, and the highest marks obtained fall considerably below those of 1908. It is encouraging, however, to notice that in Class I about fifty per cent. of the candidates were in the lower Classes last year, and other candidates of former years, if not yet in Class I, have attained a higher position than formerly. So much for the value of perseverance. The answers to the questions indicated a very fair acquaintance with the practical work of draining, trenching, manuring, soil preparation for planting, and the general cultivation of the soil. It is on questions involving thoughtful study, observation and resource that many candidates show much weakness. To attain a certain versatility of ability to deal with all aspects of the work of a public garden is a matter requiring thought and observation. The lack of these was evident in answers to Questions 5 and 13. The former merely required the expression of a few graceful curves—but many of the answers revealed the crudest lines and most inartistic ideas; and the few attempts made to answer Question 13 may be supposed to indicate a lack of knowledge of the financial side of a public garden. A marvellous deficiency in arithmetic was exposed, only four correct answers being given to ‘18 (8)’ which any boy in Standard LV at school might easily have answered. With reference to the classification and naming of trees and shrubs, the majority of the candidates were familiar with the common name of many, but were unable to give their generic or specific names. Their native countries also were but weakly known, and as to those which are distinctly ‘ British’ a general haziness of mind existed, the majority of candidates including N. American, Japanese, and New Zealand trees and shrubs as British. The scientific names and the natural habitat of the trees and shrubs of our public gardens would repay a closer study, for nothing interests the public more than to find these points well and correctly set out. An immense improvement is noticed in the understanding of the cultivation of flowering shrubs, indicated by the answers to Question 12, as compared with two years ago, when a similar question was given. Reviewing the results generally :—There is still much room for improvement, the higher standard hoped for in last year’s report having EXAMINATION OF EMPLOYEES IN PUBLIC PARKS. 93 to be still held in anticipation. A completer knowledge of garden practice and the reasons for it ; the values of phosphatic and nitrogenous manures, their comparative cost, and the quantities required ; the art of curves and the power to express them neatly on paper; arithmetical calculations for land measures and simple cash computations—such things as these, added to a more intensive knowledge of gardening specialized for public parks, are necessary to raise the employees to the standard of really first-class craftsmen whose skill is to find expression in the gardens which they serve. The higher places gained by most of the old candidates in the lists should be an encouragement to the less successful to persevere diligently with their work and try again next year. It should perhaps be put on record that there is absolutely no difference of merit whatsoever in being placed in Division A or in Division B. A first Class in one is as good as a first Class in the other. The two Divisions are only kept up for the convenience of certain public authorities. COR. HmEDER; OwEN THOMAS, JOHN W.

GO NOTES ON RECENT RESEARCH AND SHORT ABSTRACTS FROM CURRENT PERIODICAL LITERATURE, BRITISH AND FOREIGN, AFFECTING HORTICULTURE & HORTICULTURAL SCIENCE, JuDGING by the number of appreciative letters received, the endeavour commenced in volume xxvi. to enlarge the usefulness of the Society’s Journal, by giving an abstract of current Horticultural periodical literature, has met with success. It has certainly entailed vastly more labour than was anticipated, and should therefore make the Fellows’ thanks to those who have helped in the work all the more hearty. There are still, we feel, some departments of Horticulture and Horticultural Science very imperfectly represented in these abstracts, and the Editor would be grateful if any who have time at command, and who are willing to help in any special direction in this work, would communicate with him. He desires to express his most grateful thanks to all who co-operate in the work, and he ventures to express the hope that they will all strictly adhere to the general order and scheme of working, as the observance of an identical order can alone enable the Hditor to continue to cope with the work. The order agreed on is as follows :— 1. To place first the name of the plant, disease, pest, &¢., being noticed ; and in this, the prominent governing or index word should always have precedence. 2. To place next the name, when given, of the author of the original article. 3. Then, the abbreviated form of the name of the journal, &c., in which the original article appears, taking care to use the abbreviation which wiil be found on pp. 264, 265. 4. After this, a reference to the number, date, and page of the journal in question. 5. If an illustration be given, to note the fact next, as “ fig.,”’ “ tab.,’ or “ plate.”’ . LIST OF CONTRIBUTORS. 97 6. After these preliminary necessities for making reference to the original possible for the reader, the abstract or digest should follow, ending up with the initials of the contributor affixed at the close of each Abstract or Note.

Aloe dichotoma. By Leonhard Lindinger (Beth. Bot. Centralbl. xxiv., Erste Abth., Heft 2, pp. 211-253; with 4 plates).—A particularly fine specimen of this species having succumbed to disease in the Hamburg botanical garden, the author was enabled to make a thorough microscopic examination of its anatomical structure. The branching is not truly dichotomous, for remains of a terminal flower axis can be found in the forks. The number of branches is not more than two or at most three. Axillary buds are not produced regularly. The plant shows distinct adaptation to resist extraordinarily dry con- ditions of atmosphere, but in the author’s opinion (contrary to that expressed by Schenck) it obtains water from the soil by means of its roots. As the upper layers of the soil are often dried up and strongly heated by the sun’s rays, the upper part of the root is provided with a well-marked cork layer. Many, if not all, giant succulents and xerophytes are subsoil water- plants. They have the power of growing vigorously when conditions are favourable, and require for this as much water as, if not more than, other plants. Aloe arborescens puts out new growing roots when the earth becomes dry, and these grow rapidly when the plant is watered. As regards the growth in thickness of the stem, the author considers that it is not a continuous process, but is active during favourable conditions only, so that it can be compared to the ordinary increase in thickness of dicotylodons. Aloe succotvina produces every year one ring of vascular bundles and a clearly limited zone is also formed every year in Yucca filamentosa, which last is not injured by the German winter. The author considers that the monocotyledons are descended from tree-like forms with secondary growth in thickness. This ancient character is retained in the arborescent Liliiflore. The aerial stems of other monocotyledons may be different, and the result of a phytogenetically younger method of growth.—G. F’. S.-H. Alpine Garden at Bourg St. Pierre. Anon. (Gard. Chron., No. 1184, p. 216, fig. 93, September 19, 1908).—An interesting account is given of the Jardin Botanique de la Linnea at St. Pierre, a small village on the St. Bernard Pass between the Hospice and Martigny. The garden is situated about 5,550 feet above the sea level. It is managed by an international committee, the director being the well-known botanist M. Correvon. A very large collection of Alpine plants will be found in cultivation—not only those which are natives of Switzerland, but others from all parts of Europe, Siberia, and the Arctic regions.—G. S. S.

Ce Jak Anchusa or Bugiloss. By M: Geeckhout (Le Jardin, vol. xxii. No. 518, p. 200; July 5, 1908; coloured plate).-The genus Anchusa includes some thirty species, found in Europe, N. and 8. Africa, and W. Asia. The most interesting are :— A. Barreliert (syn. Buglossum Barrelieri, Myosotis obtusa)—native of Southern Kurope; blue flowers with yellow throat. A. capensis— biennial; not hardy; blue flowers with white tube. A. italica (A. azwrea)—and the Dropmore variety (grandiflora). A. myosotidiflora (A. macrophylla)—Siberian species, with fine blue flowers and yellow throat. A. officinalis—indigenous; pinkish-blue flowers. A variety A. off, incarnata has bright pink flowers. A. sempervirens—indigenous ; small blue flowers. A. tinctorra—S. France; blue or purplish flowers; root yielding a red colour used in perfumery. All these species are easily raised from seed, which is to be preferred to cuttings or division.—/’. A. W. Angadenia nitida (Bot. Mag., tab. 8233).—Nat. ord. Apocynaceae ; tribe Hchitedeae ; tropical 8. America. Climbing shrub ; leaves 4—6 inches long ; flowers in racemes, corolla yellow, with a vermilion band at the base, 14 inch long, 14 inch diameter.—G. H. Apple, Fall Beauty. By H. Garman (U.S.A. Hap. Sin. Kentucky, 17th Rept. 1905, pp. 82-84; figs.).—A description and illustration of this new dessert apple in use in October.—F’. J. C. Apple Juice, unfermented. By N. C. Gore (U.S.A. Dept. Agr. Bur. Chem., Bull. 118, Sept. 1908).—Apple juice being useful as a summer drink, experiments have been undertaken as to the best means of preventing fermentation and moulding. Sterilization, otherwise pasteurization, has been found preferable to the use of chemical preservatives (benzoate of soda) in the manufacture of fruit juices. The objections to sterilization are that it gives a “cooked”’ flavour to the juice, and that the effect is not lasting. The process can be effected in either wood or tin receptacles. The former are the better, as the juice dissolves the tin to a certain extent, though less when it is coated with lacquer. In clarification tests a milk separator was used, but this is not sufficient to produce absolute clearness. Carbonating disguises the “ cooked ”’ taste. An atmosphere of carbon dioxide on the surface of the liquid delays the formation of mould in sterilized juice when exposed to the air for a limited time. Benzoate of soda checks alcoholic fermentation, but encourages development of acetic acid ferment, which spoils the flavour.—C. H. L. Apple Leaf Blister Mite. By P. J. Parrott (U.S.A. Hap. Sin., New York, Bull. 806, December 1908).—This is a pest of increasing occurrence in the Hastern States, especially in western New York. The 102 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. application of a lime-sulphur wash as the buds are swelling and before the leaves appear, followed by the usual sprayings with Bordeaux mixture, has been found an efficient remedy.—A. P. Apple, Powdery Mildew (Podosphaera leucotricha) (Dep. Agr. N.Z., 16th Report, 1908, p. 110).—This is stated to be the fungus formerly known as Podosphaera oxyacantha, and has been very plentiful during the summer months and very destructive. Being a surface mildew it is easy to control with Bordeaux mixture. It often spreads from Hawthorn hedges, which are very subject to attack; hence this plant should not be used as a shelter around orchards.—W. C. C. Apple-Scab (Fusicladium dendriticwm) (Dep. Agr. N.Z., 16th Report, 1908, p. 110; fig.).—This disease has been less in evidence than in former years, and where systematic spraying has been carried out, the loss caused by it has been insignificant.—M. C. C. Apple-tree Measuring Worm (Ennomos subsignaria). By H. Garman (U.S.A. Hap. Sin. Kentucky, 17th Ann. Rept., pp. 79-81; figs.).—One of the looper caterpillars injuring apple leaves in the same way and at the same time as the larvae of the winter moth. The female moth, however, in this case is winged, and hatches out in June, laying eggs which remain unhatched over winter. Spraying in spring with Paris green at the rate of 1 lb. to 150 gallons of water is the only means of dealing with the pest.—F’. J. C. Apples of Maine, Seedling. By W. M. Munson (U.S.A. Hap. Stn.

Araceae, Embryology of (Sot. Gaz. July 1908, pp. 85-42, with 3 plates).—Mr. James Ellis Gow describes the ovary, ovule, and development of the ovule in Nephthytis, Dieffenbachia, and Aglaonema.—G. F’. S.-H. Aster diplostephioides. By Kekhout (Le Jardin, vol. xxii. No. 517, p. 264; September 5, 1908; coloured plate and fig.). Particularly recommended for market purposes as well as pot-culture. A distinct and handsome dwarf plant (25-30 cm. high), flowering May-June in solitary heads of a brilliant purple, with well-marked orange disc, 6-8 cm. in diameter. In habit this plant compares with Gerbera Jameson, and has the further advantage of being absolutely hardy. Like all Asters, it is easy to propagate whether by seed, division of clump, or cuttings. Sow April-May, in pots or pans, prick out in the autumn; or February— March on hot-bed, and prick out in spring. In dividing, break up the plants in spring or autumn, and let the new growths get a start, well- shaded and watered in the reserve garden. Then transfer to border. Cuttings are struck under a bell-glass, and require a little heat. Er. A, W. Aster Wilt, Fusarium sp. (Dep. Agr. N.Z., 16th Report, 1908, p. 109).—This disease has been very prevalent and generally appears just NOTES AND ABSTRACTS. 108 as the plants are commencing to flower. The roots of the affected plants are discoloured and contain a large amount of the mycelium of a fungus with pinkish coloured spore masses. This disease appears to be a soil one, and difficult to control. Asters should not be grown in infected ground for at least two years, otherwise some powdered sulphate of iron should be worked into the soil some weeks before the plants are set out. MC. Ce: Astrantia, Biometrical Researches on. (Leth. Bot. Centraldi., xxiv., Erste Abth., Heft 1, pp. 1-19).—Herr Paul Vogler of St. Gall gives some detailed researches dealing with the number of bracts, of flowers, and of male flowers in A. majyor.—G. I’. S.-H. Beet Sugar Industry, Progress of, in 1996. By C. I. Taylor (U.S.A. Dep. Agr. Report 84; May 1907).—Gives a great amount of valuable information concerning the progress in securing greater sugar yield and statistics relating to the area under cultivation of this crop in the different States. It is-pointed out that beet sugar growing is productive of great good to agricultural interests in many directions. 1d SAGs Begonia manicata. By Ad. van der Heide (Le Jardin, vol. xxii. No. 516, p. 244; August 20,1908; 1 fig.).—A plea for an old and almost forgotten species introduced from Mexico in 1840. Handsome window plant, with large characteristic leaves, adorned like the petioles with long red hairs, which form a sort of gauntlet, and give the plant its name. Abundant rose-coloured flowers. There is also a white variety, B. m. alba, and a fine variegation B. m. aurea maniculata. It thrives in the winter garden or conservatory, little or no heat being required, although rich ~soil and plenty of water are essential. Propagation, like other Begonias, by cuttings of leaf or shoot.—F’. A. W. Begonia Patria. (Le Jardin, vol. xxii. No. 517, p. 258 ; September 5, 1908).—A cross obtained by M. Lemoine from B. socotrana x B. Pearcet. It resembles B. Glowre de Lorraime, but forms a more vigorous plant with brighter inflorescence. The flowers are magnificent—scarlet, salmon, and copper, with golden under-surface—and are very persistent, lasting unimpaired for more than a month after full development. A plant only 25 c. in height will often carry several hundred blossoms.— F’. A. W. Botrytis cinerea, Observations on the Biology of. By F. T. Brooks (Ann. Bot., xxii., July 1908, p. 479-437).—Hixperiments were conducted with the well-known parasitic fungus Botrytis cinerea and the lettuce plant. Botrytis conidia were unable to infect healthy green leaves, neither could they infect plants (grown in artificial cultures) weakened by the omission of one or other of the essential elements. On the other hand conidia were capable of infecting wounded leaves just beginning to turn yellow. Though conidia have no effect on healthy leaves, if young mycelium nourished saprophytically is placed on such leaves infection occurs at once and the fungus spreads rapidly. 104 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY, In dealing with the question of direct infection of the yellowing leaves and the non-infection of the normal green leaves, the author suggests the following possibilities : (1) that some chemotropic substance present in the cells of the yellowing leaf attracts the germ-tubes, whereas no such chemotropic influence is exerted by the normal leaf; (2) that in the case of non-infection of a normal leaf some substance from the ' epidermal cells diffuses through the cuticle in sufficient quantity to neutralize the effect of the small amount of poisonous substance secreted by the germ-tubes, whereas no such substance diffuses from the yellowing leaf; or (8) that the change in the vital activities of the leaf consequent upon yellowing induces some alteration in the composition of the external cell-walls which enables the germ-tubes to penetrate. - It is left for future research to decide which of these suggestions is correct. With regard to the experiments on the mineral starvation of the host, the results agree with those obtained by Marshal Ward with Puccima dispersa, viz. that mineral starvation of the host had no appreciable effect upon the infective power of the fungus.—A. D. C. Bougainvillea Cypheri. By Aug. Nonin (fev. Hort., January 1, 1909, pp. 12,18; coloured plate).—A very fine form indeed. Flowers (bracts) nearly twice the size of B. glabra Sanderiana shown for comparison. Colour identical, a great improvement.—C. T. D. Cabbage and Onion Maggot. By J.B. Smith and EH. L. Dicker- son (U.S. Hap. Stn., New Jersey, Bull. 200, February, 1907 ; 12 figures).— In New Jersey great losses have been sustained by growers on account of the attack of these maggots upon the plants. Remedies which are successful in one district unfortunately sometimes are of no avail in others. The insects are described and their life histories given. It is considered that cultural methods of control are of little avail against the onion fly, but of great importance in the case of the cabbage maggot. It is recommended that all cabbage roots should be removed as soon as done with and destroyed; all cruciferous weeds should be destroyed ; where beds of turnips, &c., have been badly affected, the ground should be ploughed late in the autumn and again early in the spring ; when a crop is found to be badly infested early in its growth it should be dug in deeply; rubbish heaps should be burnt and outbuildings, &c., cleansed by sulphuring or whitewashing. The time of sowing onions also has some influence on the amount of damage done. Late sowing both in autumn and spring was found to be followed by the best results in New Jersey, as the various broods of flies were then avoided. Quick-acting fertilizers are useful, since they bring the plants rapidly over the season when attack is most to be feared. Cabbages and cauliflowers should be firmly planted, since then the newly hatched larva will be unable to make its way down through the hard soil so as to find a part of the cabbage sufficiently tender for it to attack. Various substances were tried, with varying amounts of success, aS preventives, including tarred paper cards placed round the stem of the plants upon the soil, carbolic acid and lime, kerosene and sand, powdered tobacco, powdered white hellebore, dry lime, bran and glue ; and as destructive measures, the application of carbon bisulphide, carbolic- NOTES AND ABSTRACTS. 105 acid emulsion, hellebore decoction, and other things ; and carbolized lime is thought to be the best thing to use. It is made as follows, and is to be applied early, frequently, and thoroughly. ‘The lime is slaked to a thin cream ; three pints of the cream are added to a gallon of water and then a tablespoonful of crude carbolic acid, and the mixture is applied by means of a sprayer along the rows so that the surface of the ground is covered.—F’. J. C. Cabbage, Insects Injurious to. By H. Garman (U.S.A. Hap. Sin. Kentucky, 17th Ann. Rep., 1905, pp. 20-47 ; 17 figs.) Cases have been reported where poisoning following the eating of cabbages which have been sprayed has occurred. It is pointed out that if reasonable precautions as to stopping spraying sufficiently long before the plants reach a marketable size, are taken, there is so little of the spray left that there is no possibility of poisoning occurring. Analyses are given demonstrating this. The insects attacking the cabbage are then described and figured, and appropriate remedies, usually spraying with arsenical sprays, such as Paris green or arsenate of lead, are recommended. The insects dealt with are the white butterflies or cabbage worms (Pontia rapae, the well-known British small white butterfly, and-P. protodice, the former being the most troublesome of all the insects attacking cabbage), the larvee of the moths, the cabbage looper (Autographa brassicae), the southern cabbage moth (Hvergestes rimosalis), the cabbage Plutella (Plutella maculipennis), an insect of world-wide distribution, the zebra (Mamestra picta), the army worm (Heliothis unipuncta), the corn worm (H. armuger), the woolly bear or tiger moth (Diacrisia virginica), the cutworms (Peridroma margaritosa, Agrotis ypsilon, Prodenia ormthogalli, and Mamestra trifoli), the flea beetles (Phyllotreta vittata, P. sinuata, and Systena blanda), the spotted cucumber beetle (Diabrotica 12- punctata), the margined blister-beetle (Hpicauta marginata), the harlequin cabbage bug (Murgantia Iustrionica), the false chinch bug (Nysvus angustatus), the cabbage plant louse (Aphis brassicae) the cabbage leaf-miner (Drosophila granunum), the turnip leaf-miner (D. flaveola) the cabbage Anthomyia (Pegomya fusciceps) and the onion thrips (Thrips tabact).— fF’. J. C. Camassia esculenta. By C. Potrat (Le Jardin, vol. xxii. No. 517, p. 262; September 5, 1908; 1 fig.).—A vegetable, one of the Liliaceae, indigenous in California. It has the advantage of being a pretty garden- plant, 18 inches high, with bright green leaves and blue flowers, of the Ornithogalum type. Two horticultural varieties are C. e. alba and C. e. atro-coerulea. The plantis hardy, but resents damp. When roasted, the bulb (which is the edible part) has a flavour between a yam and a potato. Flour prepared from it is used in confectionery, and as a remedy for coughs. Cultivate from seeds or offsets. Sow the seeds in July-— August, when ripe. Prick out September-October, when the bulbils may also be planted. These will produce flowers the next year, but plants from seed require two years to come to maturity. Flowers May—June.

No. 513, p. 202; July 5, 1908).—This plant is worthy of cultivation as a winter vegetable. Both leaves and root have an agreeable flavour; it may be eaten raw, as salad, or cooked like spinach. The root resembles a crisp white radish. The plant is easily raised from seed, but late sowings (end of June or July) are advisable—otherwise it is apt to run to flower. As the young plants are at first very tender and habie to dry off, it is well to shade them by simultaneously growing some other vegetable, such as summer radishes, which are lifted before the raiponce reaches perfection. It is ready in October and can easily be protected from frost by a light frame and mats.—/". A. W. Carica Papaya. By C. Bernard (Ann. Jard. Bot.

Ff. D. Carnations, Sporotrichum Bud Rot. By F. C. Stewart and H. E. Hodgkiss (U.S.A. Exp. Sin. Geneva, N.Y. Tech. Bull., October 7, 1908 ; 4 plates).—Carnations affected with bud rot are invariably infested with a certain funeus (Sporotrichum anthophilum, Pk.) almost constantly associated with a particular species of mite (Pediculoides dianthophilus, Wol.). Outwardly the affected buds usually appear like normal buds partially opened, but internally they are brown, decayed, and generally mouldy. The stamens, styles, and lower portion of the petals are attacked first; frequently the pistil also is affected. The brown decayed tissue is permeated by the mycelium of the fungus. Experiments prove that the Sporotrichum alone is capable of producing the disease. All affected buds should be picked and burned as soon as they appear.—W. C. C. Ceratozamia, Seedling of. By Helen A.

When separated from the plant both internodes and leaves are capable of producing both tubers and adventitious roots. The free-hang- ing branches grow at the tip and their adventitious roots remain quite short, but if laid on the ground the latter form strong branching roots NOTES AND ABSTRACTS. 107 which enable the main shoot to grow more vigorously. When grown in water, the want of nourishment seems to produce an increased formation of tubers and of adventitious roots. The plant can exist and form new erowths when supplied with cane sugar only, but not when glycerine is used. If the growing point is prevented from development, the axillary shoots increase greatly, and the formation of tubers is also favoured, especially when the plant is prevented from forming axillary shoots. Tuber formation is favoured by darkness.—G. F’. S.-H. Cherry ‘ Bigarreau tigré.’ By Max Garnier (Rev.

In Western Virginia about one-half of the cross-ties on local railroads are chestnut oak, while for furniture, farm implements, tool handles and in wagon-making the wood is largely employed. Not only is the chestnut oak valuable for its timber, but the bark is extensively used in the tanneries, and employed on account of the tannic acid it contains. The management of the tree, list of insect pests, susceptibilities to fire and injury by grazing, and reproduction by seed and sprout are all care- fully explained.—A. D. W. Chile Culture. By Fabian Garcia (U.S.A. Haup. Stn., New Mexico, Bull. 67, 1908 ; illustrated).—The chile is largely grown in New Mexico for home consumption. The taste for it among Americans is on the increase. It is rather less tender than the tomato, and can be sown in the open early in April, or raised in frames end of January and planted out. This is the best, though less common way. The chile resists drought fairly well, but, as it continues bearing as long as it is kept growing, irrigation is valuable. The pods, when ready for picking green, should be smooth, shiny, and from 4 to 6 inches long. Chile is canned when green, or eaten fresh (both green and ripe). C.

H. Clitoria arborescens, Pollination of. By A. F. (Bull. Bot. Dept., Trin., No. 58, April, 1908, p. 79)—From the writer’s minute observations and careful experiments it appears that the pollination is effected through three distinct processes. 1. It is mechanical, and consists of (first) a sinistrorse and (secondly) a dextrorse gyration of the carina, in which the pollen is brushed from the anthers by stylar brushes into the funnel of the carina. 2. Heavy insects, viz. bees and wasps, visiting and shaking the flowers, cause the pollen to fall into the concavity of the vexillum, whence some grains on the insect’s legs are transported to other flowers, and fall into a small protected space formed by the bases of the vexillum and the free anther, the latter helping to rub pollen from the insect. 3. Ants, which visit the flowers freely, carry pollen grains attached to their bodies, and leave them on the stigma. Protected blossoms artificially dusted with their own pollen were in no instance fertilized. Under similar conditions cross pollination resulted in a 93 per cent. fertilization. One plant only has been experimented with, and the writer suspects small flying insects may effect fertilization in its natural habitat, and hopes to make further investigations.—LH. A. B. Codling Worm, Spraying for. By H. A. Gossard (U.S.A. Hup.

There is nothing very definite in the conclusions as to the relative merits of these different washes (p. 117), but the results of the sprayings were very marked, the net profit from spraying (p. 125) an average-sized tree from twelve to twenty years old in one season, at a cost of 30 to 50 cents, being estimated at 83 to $7 when the apples were worth $1 per bushel, a con- NOTES AND ABSTRACTS. 109 servative estimate of the profit from spraying the whole orchard being $1,400 (p. 121); trees of the same size (standards 20 feet in height and diameter) in neighbouring unsprayed orchards produced less than one- fourth as much marketable fruit. At least three sprayings annually are recommended to secure good results (p. 125), some growers in the district making five or more; and the essentials for success are stated to be thorough work, applications at the right times, and a good spraying outfit —in this case a gasoline power pump, a 250-gallon tank on trucks with an elevated platform, and bamboo extension rods ten feet long, each terminated by a cluster of four Vermorel nozzles. Paris green is not recommended for the July spraying, as it is considered to cause excessive falling of the fruit due to the burning of the stems, while Bordeaux mixture or arsenical compounds in cold wet springs conduces to excessive russeting in the fruit (p. 111).—A. P. Cold Chambers, How to construct. By S. F. Walker (Gard. Chron., No. 1141, p. 321, figs. 185, 186, and 187, November 7, 21, and 27, 1908).—Very concise directions are given in this paper for the construc- tion of cold chambers, in which cut flowers may be kept fresh for long periods and plants in bud may be retarded. The writer, in mentioning various substances which are more impervious to heat, hardly seems to realize that it is not the matter of which the substance is composed, so much as the amount of air that they contain, which make them good or bad conductors of heat, though he admits that ‘‘ of all thermal insulators still dry air is by far the best.’’ Yet he writes of filling the space between two walls with some insulating material, and ramming it well down. One would have thought that if the material was put in lightly it would have been more efficacious; some is wanted to prevent currents of air being set up.—G. S. S. Coniferous Conescales. By Dr. Aug.

Heft 1, pp. 27-44; one plate)—Dr. Bayer by anatomical sections, by the examination of abnormal cones of Cryptomeria, and by studying the embryonal development, confirms Velenovsky’s interpretation of the conescales of this genus. Whereas the ovule is borne on a simple carpel in Juniperus, Thuja and Chamaecyparis, the conescale in Cryptomeria is a bract to which is fused a reduced axillary shoot; the teeth of the bract represent so many fertile ovule-bearing carpels which belong to this rudimentary shoot, but are united with the bract.—G F’.

Jaks Tage, JDy Cotton Wilt. By W. A. Orton (U.S.A. Dep. Agr. Farm. Bull. 338, 1908 ; with 11 woodcuts)—The most characteristic symptom of wilt is a browning of the woody portion of the stem and root. These dis- coloured parts are the water-carrying vessels which have become obstructed by the development in them of the fungus causing the disease. 110 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. The “wilt fungus’’ is reported as Neocosmospora vasinfecta (Atk.). It lives in the earth on decaying organic matter until it encounters the small feeding roots of the Cotton, which it enters.

Land-Forst), Vol. 7, pp. 54-75, 87-114, and 129-160, 8 figures, January, February, March 1909).—This investigation deals in an ex- haustive manner with questions of importance in diseases of plants. It is not sufficient to name a fungus or other cause in investigating disease, and recent work has been much more directed towards investiga- tion of disposition to disease. A plant is said to be immune when it is in such a condition that it is not attacked by a disease-producing agent. Disposition arises from various conditions, such as locality. The author distinguished “ disease-receptivity ’’ as a condition of the plant which favours disease. Thus a plant must be frost sensitive before it can be damaged by frost. The results obtained in this paper may be best illustrated by an example. Pine wood is immune against a particular fungus (Ceratostomella) if the volume of air in the fresh wood is below 15 per cent.; with increasing air-volume this fungus grows better and has its optimum growth when the air-content is 42 per cent. of the volume of the wood. This was found to be the case with other fungi, including Nectria, the tree-canker fungus. The results lead to the following general principles: the relationship between immunity and receptivity on the one hand, and air-content on the other, holds good for living plants as well as dead stems; different parasitic fungi have different air-requirements.— W.

The researches of Thouvenin and Pollacci have- already proved that under electrical currents the process of assimilation is more active 161192 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. and energetic provided the currents are not so strong as to injure the tissues. The author cannot confirm Pollacci’s observation that even in the dark, electrical stimulation will produce assimilation. His own experiments were carried out with plants of Hlodea placed in water. When the current passes from the base to the tip, assimilation is favoured, but when it passes in the reverse manner, the current has an injurious effect. When the current passes through the water only, it has also a favour- able effect, however the plant is placed (parallel to or at right angles to the stream lines), except when passing from the tip to the base, when it is decidedly injurious. It is apparently comparatively easy to electrocute Hlodea. With a sufficiently weak current the stimulation of assimilation can be carried on indefinitely.—G. Ff’. S.-H. Encephalartos Barteri (Bot.

Endosperm of some Graminaceae, The Vitality and Self- digestion of. By D.Bruschi (Ann.

It is shown that the starchy endosperm of maize, barley, wheat, and rye can digest itself in the absence of the scutellum and other parts of the embryo, though to a very different degree. The self-emptying can go on in the absence of any vitality in the amyliferous cells, because the starch hydrolysis is accelerated by a strong arnylose which arises from a pro-enzyme existing in the endosperm of the resting seed, and becomes active even though every trace of vitality has been removed from the entire endosperm. Vitality is not, however, wholly denied to the endosperm cells. It is possessed by the aleurone cells at the periphery of the endosperm and also in one or two sub- aleuronic layers, whence it lessens by degrees till it completely disappears towards the middle of the endosperm.—A.

These sprang from Gymunosperms which re- sembled Cycas, Anomozamites and Cycadeoidea in appearance. He supposes the lines of descent to be somewhat as follows: Julianales (also Juglandales, Anacardiaceae &c.) from Terebinthaceae, Rutaceae, Saxifragaceae, Hamamelidaceae, Illicieae, Magnoliaceae. The paper is of great importance in connection with the vexed question of the descent of Angiosperms.—G. F’. S.-E. Evolution, Methods and Causes of. By O. F. Cook (U.S. Dep. Agr., Bur.

Flower-honey contains a much larger amount of water and more saccharose than bee-honey, which last contains dextrin, nitrogen, and formic acid. None of these substances occur in the flower-honey. The fodder-hairs resemble pollen in containing fatty acids and nitrogenous substances, but are much richer in nitrogenous material. The wax of Ornithidiwm is used, in his opinion, for propolis; it both guides larger insects to the flower and also keeps off unbidden guests which often get stuck on the sticky surface. It is especially flowers that have no pollen to spare that produce it.—G. F’. S.-E. Forest Scenery of Cameroons. By Dr. F. C. von Faber (Beth. Bot. Centralol. xxii. 2'e Abth.

The rainfall at Bibundi reaches the enormous amount of 11,900°65 | millimetres, which is one of the heaviest known in the world. The chief peculiarity of the vegetation is the rich rain-forest or tropical wet jungle which ascends the mountains sometimes to 2,000 m. altitude or in ravines to 2,700 m. There are clear and interesting descriptions of the mangrove creeks and of the way in which the mangroves give place to other plants when the soil level becomes higher than that of ordinary high tides.

The losses were most pronounced upon young apple orchards; the per- centage of seriously injured trees ran extremely high and with certain varieties was astonishingly large. ‘The investigations will no doubt prove extremely valuable in determining which varieties of apple are most suitable for withstanding severe frosts, and under what conditions of growth and soil, and other surroundings, they are safest from injury. Ane as Frost, Notes on. By E. B. Garriott (U.S.A. Dept. agr., Marmers’ Bull. 104, 1908).—In the States protection against sevcre frost is very essential, as it often means saving the life of acres of plants and trees, and also makes it possible to put an early and paying crop on the market. This protection is applied to orchards, berry plantations, and vegetables, and is effected in different ways according to situation, extent of land, and duration of frost. Irrigation, flooding, and spraying with water, by supplying moisture to the air, lessens danger from frost. Smudge fires, produced by burning damp material such as straw, manure, or prunings are a recognized means of protection, and should, to be efficacious, be numerous and well distributed. NOTES AND ABSTRACTS. 115 Where coal is used to raise the temperature, twenty to fifty baskets of fire are required to the acre. Other means of protection are earthing-up, mulching with hay, and screening of light material. The forecasts of the Weather Bureau are an invaluable aid to growers. peda kee bp Frost of April 19-20, 1908. By L. Chasset (La Pomologie Fran- caise, June 1908, p. 163).—The effect of the frost is not entirely shown by the number of flowers that open on the day of the frost and the follow- ing days; their opening is not hindered, but upon attentively examining the pistils and stamens, one sees that they are blackish from the time of the opening of the petals. The varieties of Pear that resisted the frost best were ‘Beurré Clairgeau,’ ‘Triomphe de Vienne,’ and ‘ Marguerite Marillat ’; although the following varieties were planted by the side of these three, in spite of the abundance of blossom none of them bore fruit: viz. ‘Beurré Hardy,’ ‘ Le Lectier,’ ‘ Duchesse d’Angouléme,’ ‘ Figue d’Alencon,’ ‘ Beurré Diel,’ ‘ Directeur Hardy,’ ‘ Belle Angevine,’ ‘ Beurré gris.

The remedy suggested against the last is to shake the beetles into a pail of water covered with a film of coal tar. It was found that the insects very frequently inoculated the fruits which they bit with the spores of the brown-rot fungus, fruits which were protected from being bitten by a muslin cover or by spraying remaining perfectly healthy.—/’.

(Woburn, Ninth Report, 1908, pp. 80-86).—The hexagonal arrangement produced an improvement in results as compared with planting on the square, but the experiment was on too small a scale to justify a modification of the conclusion previously drawn—that the slight improvement is not worth consideration in comparison with the cultural advantages presented by the square arrangement.—A. P. Fruit Trees, Chemical Manures for. (Jowr. Soc. Nat. Hort. Fr., p. 768, December 1908).—According to the writer, owing to the character of their root system, chemical manures are not so suitable for fruit trees as organic manures.—MV. L. H. Fruit Trees, Influence of the Date of Planting. By the Duke of Bedford, K.G., and Spencer U. Pickering, F.R.S. (Woburn, Ninth Report, 1908, p. 73).—Twenty-nine out of forty-two trees planted on November 14 showed the formation of rootlets by January 16 following, the plum stocks having made the greatest number of rootlets, and experiments lead the authors to the conclusion that where planting cannot be done till late in the season it is best to defer lifting the trees from the nursery till the eround is ready to receive them. ‘The advisability of cutting trees at the time of planting, even when the trees are planted late in the season, is still maintained (pp. 74-75).—A. P. Fruit Trees, Planting above the Ground Level in Heavy Soils. By the Duke of Bedford, K.G., and Spencer U. Pickering, F.R.S.

By G. Fron (Jour. Soc. Nat. Hort.

The operation is admitted to be a delicate and dangerous one, and the results are so far so little assured that it is on the whole advised rather to renew the soil round starved trees or to transplant those in unsuitable positions — MV. LZ. H. Fruit Trees : Ramming the Soil when Planting. By the Duke of Bedford, K.G., and Spencer U. Pickering, F.R.S. (Woburn, Ninth Report, 1908, pp. 7-80).—The soil was rammed with a heavy rammer till the whole was thoroughly puddled and shook like a jelly at each stroke. The number of cases where this treatment produced increased growth in the first and second seasons after planting, compared with that of trees carefully planted in the usual way, was from four to six and a half times greater than where the opposite was the case. As regards fruiting, no positive conclusions could be drawn. The authors explain the results as being due to the closer contact of the soil aiding in the formation of adventitious root-fibres from the main roots, where there is the greatest store of food material; the fibrous roots, which we have always been told to spread out so carefully, containing but little accumulation of reserve NOTES AND ABSTRACTS, ELT material out of which new rootlets may be made, and on trees which have undergone a journey, at least, seldom making any but the feeblest growth. The scientific basis of the results of this improved contact of the soil with the roots, and of the varying behaviour of the latter when rammed in different soils, is dealt with in an article by Mr. Pickering in his “ Studies on Germination and Plant Growth” in the Appendix to this Report (reprinted from the “ Journal of Agricultural Science.” vol. 2, part iv.). Ane. Fruit Trees: Root Injury on Planting. By the Duke of Bedford, K.G., and Spencer U. Pickering, F.R.S. (Woburn, Ninth Report, 1908, pp. 88-56).—The conclusions arrived at confirm those expressed in the Fifth Report: namely, that the various items which are supposed to con- stitute “bad practice’? in planting are not only not deleterious to the trees, but result in a certain amount of good, and the authors justify this by referring to experiments which go to show that trees benefit by the removal of fibres up to 1 mm. in diameter, as well as by the shortening of the larger roots, the latter practice helping the formation of more vigorous adventitious roots nearer the stem, and they maintain that it is the formation of new roots, and not the preservation of old ones, which should be the aim in planting trees.—A. P. Fruit Trees: Trenching the Soil before Planting. By the Duke of Bedford, K.G., and Spencer U. Pickering, F.R.S. (Woburn, Ninth Report, 1908).—The bastard trenching of the soil before planting has not, as a rule, produced any good results, and the authors advise growers not to go to the expense of trenching without strong evidence that such a _ process has actually been found to be beneficial to the particular soil in | question. Where the-soil is deep and fertile it may have good results, as _ well as in cases where it improves the drainage.—A. P. | Fruits in Virginia and South Atlantic States, Orchard. By | H. P. Gould (U.S.A. Dept. Agr., Bur. Pl. Ind., Bull. 185, December _ 1908).—This is the first published report of the fruit district investiga- tions of the Bureau of Plant Industry, and the object in making them has been to ascertain the limitations within which fruit varieties may be _ profitably planted in these regions, as indicated by the manner in which _ they respond to the influences of their environment, the success of a given _ variety being not alone “its ability to develop to a high degree of per- _ fection, but its commercial value in terms of profit and loss when placed upon the market” (p. 9). Based upon the observations of 63 growers, _ descriptions are given of all the varieties of fruits commonly grown in the districts in question (pp. 30-62) with their varying behaviour at different elevations and in different soils, and these are supplemented by elaborate phenological records by the same observers (pp. 68- ~95). For instance, there are returns by 53 growers on Ben Davies apple, giving the latitude, elevation, slope, and soil where it was grown in each case, with the dates of blossoming in given years and of the last spring and first autumn frosts, the times of gathering, the periods of its season, &.

P. Fumigation of Nursery Stock, Tests of Gases for. By W. E. Britton (Journ. Ec. Entom., I. (1908), Pt. 2, pp. 110-112).—These tests were undertaken with a view to find some gas more convenient than hydrocyanic acid gas for fumigating small parcels of nursery stock. The fumigation was carried out in an oblong box, and two generators were used—one at each end. Apples infested with San José scale were used. The gases tested were carbon bisulphide, carbon tetrachloride, sulphuretited hydrogen, and chlorine, while for purposes of comparison hydrocyanic acid gas in three different quantities was used. No recommendations are yet made. Carbon bisulphide. This was volatilized in iron pans which had been heated. When used at the rate of 10 oz. to 100 cubic feet for one hour, 4°3 per cent. of the scales survived and one tree died. When 60 oz. of carbon bisulphide to 100 cubic feet was the charge, allowed to act for three hours at 59° F., all the scales were killed and the trees uninjured. After being exposed to gas of a strength above this, half the trees failed to grow. Carbon tetrachloride. All the scales were killed and the trees were uninjured where 80 oz. or less to 100 cubic feet was used and allowed to act for two hours. Hydrocyame acid gas. Generated with 1 oz. of potassium cyanide to 2 oz. sulphuric acid and 4 oz. of water to each 100 cubic feet, all scales were killed. In one case, after fumigating for halfan hour, one tree died. In most other cases the trees were uninjured, even by larger quantities of gas acting for a longer period. Sulphuretted hydrogen. Generated from iron sulphide 20 o2z., sulphuric acid 80 oz. (fluid), water 32 oz. (fluid). The quantity of iron sulphide for 100 cubic feet was 9 lb.; and other strengths used were 123 lb. and 25 lb. Im the last case 20 per cent. of the trees were injured after fumigation for two hours; but in other cases no injury followed, and all the scales were killed. Difficult of application, on account of the long time taken to generate the gas. Chlorine. Generated from bleaching powder 14 oz., sulphuric acid 17 oz. (fluid), water 70 oz. (fluid). The quantities used varied from 8°6 lb. to 84°7 lb. to each 100 cubic feet, and all the scales and most of the trees were killed.—F’.. J. C. Galanthus plicatus. By S. Arnott (Garden, January 1909, p. 18). —The author describes G. plicatus, and refers to G. Fraser, Chapel, and other garden varieties of this Snowdrop. He thinks they enjoy the same garden conditions as the common Snowdrop, but are liable to die - off without apparent cause, and are subject to the fungoid disease which attacks Snowdrops of any species.—H. R. D. Gardenias and their Culture. By Ad. van der Heide (Le Jardin, vol. xxii. No. 514, p. 213; July 20, 1908).—The Gardenia was introduced from India in 1754. G. florida fiore pleno is known to everyone. NOTES AND ABSTRACTS. 119 A less common variety, G. f. Fortuneana fl. pl., was brought to the Royal Society from China. It bears large white blooms like Camelha alba plena, but is seldom seen now. G. f. radicans Thunberg, intro- duced from Japan by Fortune, a dwarf plant, with tiny double flowers, very sweet scented (erroneously termed Cape Jessamine), and G. florida foliis variegatis have both died out. Others worthy of culture were G. amoena (Simson), with single flowers, pink and white upon the same corolla; G. citriodora, pure white lemon-scented flowers; G. Stanleyana Hooker, from Sierra Leone (1840), flowers on long tubes like a Datura, white, with purple blotches, and many others are enumerated in this article. The French culture of G. florida fl. pl. differs from the English inasmuch as the flowers are wanted for the Paris winter market. Cuttings are struck in January in greenhouse or hot-bed, and trans- ferred to pots of successively larger sizes, keeping in warm house till June. They are then planted out in heath mould, and left in the open till October, when they should be transplanted to the hot-house and watered freely. This makes them break into full bloom. When the flowering season is over the old plants are burned for firewood. The practice of planting out during the summer lessens the danger of insect pests, to which Gardenias are so liable. It is, however, well to make precautionary use of insecticides.—l”. A. W. Germination of Hard Seeds: Hot Water Method. By J. Tixier (Le Jardin, vol. xxii. No. 515, p. 285; August 5, 1908).—The author. tabulates the results of his experiments for three years with seeds which are prevented by a hard shiny coat from ready germination. Method.—Take quite boiling water, and keep it on the boil. Plunge in a small sieve or pocket of wire gauze containing a very few seeds, and leave it in the boiling water for a time determined in each case by the hardness of the seeds. (Next, for small seeds, plunge into cold water ; but omit this for large seeds.) Sow in pots,.or in the open, according to nature of seed. Only a few should be dipped simultaneously, in order to ensure full action of the boiling water, which dissolves the hard varnish they are coated with. In some cases, where soaked seeds have germinated according to the following table, and the controls (unsoaked) have remained unchanged for three months, a subsequent treatment with boiling water has induced germination at the normal period.

Sc.) has calculated the influence of the hygrometric state of the atmosphere on the vitality of seeds. He finds that when it exceeds 0:7 at a tempe- rature of 25° C. many seeds perish: the Cruciferae are among the most resistant. A drier atmosphere is more generally favourable, but chervil, poppy, and Digitalis suffer in dry air. Parsnips can stand a hygrometric depression to 0°3.—F’. A. W. Gnetum Gnemon, Embryo of (Bot. Gaz.

Grafting, Modifications in the Constitution of Plants produced by. By M. C. Laurent (Jowr. Soc. Nat. Hort. F'r., p. 718, December 1908).—These modifications are of three sorts—in external appearance, in chemical constitution, and in resistance to parasites—and the result of M. Laurent’s investigations goes to prove that the actual chemical com- position of grafted plants differs from that of either stock or scion on its own roots.—WV. L. H. Growth, Laws of. By Georg Ritter (Beth. Bot. Centralbl. xxiii. 1% Abth. Heft 3, pp. 278-819).—This is an important biometrical study of the growth in length, in surface and in cubic contents of various plant organs such as internodes, length and size of seeds, dimensions of leaves in various habitats, &c. The author concludes that, in organic growth, the law of Quetelet is on the whole confirmed. Up to a certain point the process of formation seems to be independent of external conditions. A tendency to exceed or fall short of the mean is regulated by inheritance and must be inherent in the protoplasm. When material has been obtained from different localities in which selection has been at work, the curves found show distinct differences. New culminating points may appear, and there may be a change in the value of the mean character. When a new maximum has been established by selection, the development may be discontinuous but is still on the same lines, and is only influenced by degrees. This holds of Giantism, Nanism, Malformations, Anomalies, &c. The author remarks how the so-called Fibonacci series seems to under- lie the laws of growth in almost all the cases studied. These extracts may serve to show the importance of this paper in biometry, but it is exceedingly difficult to give any satisfactory abstract of the author’s conclusions without a far larger space than is here available.

California, Bull. 200, 1908 ; with NOTES AND ABSTRACTS. 121 14 figs.).—Gummosis is a term applied to a condition in which an exuda- tion of gummy sap takes place through the bark. Such a flow of gum is almost always connected with a dying or unhealthy condition of the tree. Such troubles are particularly characteristic of two classes of trees, citrus and stone fruits. The most important consideration in regard to the control of gummosis is the fact that, since the disease is brought about solely by unfavourable conditions, it can be more easily prevented by avoiding those conditions than it can be cured after once started. In the choice of location heavy wet ground should be avoided, unless it can be drained or improved in some manner.—WV. C. C. Helianthus or Salsify. By P. Graebner (Not. Konig. Bot., Berlin, No. 44, p. 107, 108).—In recent years the name of Helianthus or Salsify has been given in commerce to a plant of extraordinary productiveness. It grows to a height of 10 feet, and is used as food for cattle, and the tubers as a vegetable. The author identifies itas Helianthus macrophylla. S. H. W. Horticultural Society, Indiana, Report of the Proceeding’s of the year 1907.—As usual in these Transactions of American Horticultural Societies, the apple claims the greatest attention. In Indiana apparently neither climate nor situation generally is really quite suited to fruit culture, but much can be achieved by intelligent care ; and one paper in this volume recounts the adventures of a special train run over the system of the Baltimore and Ohio South-Western Rail- road under the auspices of that Railway Company, the Purdue Experiment Station, and the State Horticultural Society. The train carried lecturers, magic-lantern apparatus, samples of fruit, and diagrams of various sorts, and preached the gospel of fruit-growing in towns, villages, and to hastily summoned buggy-loads of interested farmers at wayside stopping-places through a long strip of Southern Indiana. Other subjects treated of in this volume are melon, potato, cherry, onion, peach, pear, strawberry, and plum culture ; remedies for and prevention of the attacks of garden pests ; marketing fruit, cider and vinegar making, the State inspection of orchards and nursery stock; and spray mixtures. An account is also given of a successful method of protecting orchards from severe frosts by lighting fires of wet straw or wet stable manure here and there among the trees. On fairly still nights the smoke, mixed with the fog produced by the condensa- tion of the steam from the wet fuel, hangs low over the trees and acts as a screen to check the radiation of heat from the plants, and even increases the temperature of the air to a considerable height above the ground. Mis Ff. Inflorescence of the Pear and the Apple, Notes on the. By Claude Abrial and L. Chasset (La Pomologie Francaise, August 1908, pp. 243-5).—In apple the terminal flower is the largest and expands first, the lateral flowers expanding from the periphery towards the centre like an ordinary corymb. In the pear, on the contrary, the corymb is indefinite, only the flowers of the periphery are fertile and the central flowers are sterile; in the Williams’ Pear, the flowers of one corymb expand almost 122 JOURNAL OF THH ROYAL HORTICULTURAL SOCIETY. all at the same time, the flowers at the outer edge open more widely than those of the centre ; the three flowers which terminate the cluster do not expand at the same time, the most central flower expands at the same time as the other flowers of the cluster, while the two which accompany it are still in bud. Only a small number of flowers borne by a tree are destined to give fruits ; most act as male flowers producing a considerable quantity of pollen. If the flowers are thinned in the apple the lateral flowers would be cut out, keeping the terminal ; if the terminal is missing, leave two or three of the innermost. With the pear, on the contrary, the central flowers would be cut out and the lateral ones left. The number of flowers left would be ruled by the variety, the varieties with small fruit having the most flowers left. | Photographs of pear inflorescences show two central flowers already fallen, and the small flower at the extremity ready to fall, whilst two outside fruits springing from the base of the cluster are well set. The photographs of apples show the central fruit larger, and stem more fleshy, whilst those at the base, on the contrary, have thin stems and fruit hardy formed. | The hope is expressed that research will be made to find out which varieties of Pears and Apples are the best suited as fertilizers (i.e. pollen producers).—C. H. H. Insecticides—Nicotine, Lead Arsenate, and Paraffin Emulsion. By the Duke of Bedford, K.G., and Spencer U. Pickering, F.R.S. (Woburn, Tenth Report, 1909, pp. 85-42).—Further experiments were made in continuation of those detailed in the Eighth Report (p. 83) to test the comparative insecticidal effect of these three washes. Nicotine was not successful with caterpillars generally, and quite inoperative against the winter moth caterpillar, which was completely destroyed by paraffin emulsion (solar distillate 15 per cent. emulsified with iron solution), as was also the grub of the gooseberry and currant sawfly. The emulsion was much more effective than lead arsenate and did not interfere with the sale of the fruit, but it cannot be used while the trees are in blossom. The experiments were mainly restricted to these two pests. Parafiin emulsions are quite harmless if properly made, but the precaution of churning them up again with a syringe should always be taken (pp. 48-46). APs Ipomoea mexicana grandiflora alba. By B. Chabaud (Rev. Hort., December 1, 1908, pp. 552, 553).—F rom the description this Con- volvulus is extremely attractive, the flowers being very large and sweetly scented. It flowers, however, in the evening and fades early in the day ; but as it flowers for a week after cutting, this drawback is largely dis- counted. It is also known as the ‘ giant white Ipomoea.’—C. 7. D. Iris germanica. By P. de Vilmorin (Jowr. Soc. Nat.

By Ph. de Vilmorin (Rev. Hort. December 1, 1908, pp. 544, 545; coloured plate)—Two very beautiful NOTES AND ABSTRACTS, 123 varieties are figured: ‘Isoline,’ standards very wide, white, tinged with violet at margin, yellowish at base, falls long and decumbent, light violet red, with brown streaks at base; and ‘ Diane,’ plant somewhat dwarf, but flowers equally large, standards light lilac, falls widespreading and darker in tint with brownish-orange basal stripes.—C. 7. D. Japanese Maples. By J. Clark (Gard. Chron., No. 1,188, p. 278, October 17, 1908).—The author of this paper says that ‘“ many species of Acer are indigenous to Japan, but the term ‘ Japanese maple’ is ordinarily applied in gardens to Acer japonicum and A. palmatum together with their respective varieties. ‘The former of these was introduced to this country, according to Loudon, in 1820, and the latter some forty years later. These maples are perfectly hardy, not fastidious as to soil and situation, provided the latter is not too shaded. They are lable to be cut by late spring frosts, but they quickly recover from its effects.” A selection of Japanese maples that can be recommended to the ordinary planter, some fifteen in number, is then given with a short description of each variety. —G.S. 8. Java; the Virgin Forest of the Equator. By M. Treule (Ann. Jard. Bot. Buit., vol. vil., pp. 144-152).—In a primeval forest in the rainy district of the west of Java the leaves of the giant trees are covered with lichens and mosses ; the branches bear innumerable orchids, Gesneraceae, Piperaceae, and ferns. ‘The trunks of the trees support climbers. Hach giant tree exhibits a combination of all kinds of vegetable forms: a rich and varied flora. The undergrowth of the forest abounds in tree ferns, palms, Pandanus, and Musaceae, and in their shade flourish innumerable herbaceous plants. The whole is traversed by lianas and aérial roots. Not only a struggle for existence takes place in the virgin forest, but also on the other hand co-operation and federation. In an artificial wood planted forty years ago solely with Schima Noronhae (in a similar situation to the virgin forest just mentioned), 140 species of plants occur in an area of 4 hectares. The complete absence of lianas and epiphytes formed a striking contrast to the primeval forest. S. H.W. Kaulfussia and Gleichenia, The Prothallia of. By D. H. Campbell (Ann. Jard. Bot. Buit., vol. vii., pp. 69-99; 8 plates)—The prothallium of Kawlfussia is larger than that of the other Marattiaceae, but closely resembles it in structure. An endophytic fungus is always present. The antheridia are restricted to the lower surface of the midrib. In their large size, as well as in the larger spermatozoids, they resemble Ophioglossum. The development of the embryo is similar to that of the other Marattiaceae. The cotyledon emerges from the upper surface of the prothallium and resembles that of Ophioglossum in form and venation. The prothallium of Gleichenia possesses a massive midrib. An endophytic fungus is always present. In G. laevigata the antheridia occur on both sides of the prothallium ; in all other species they are confined to the ventral surface. G. laevigata has the largest antheridia, and G. poly- podioides the smallest. The embryo appears to resemble in its early divisions that of the Polypodiaceae.—S. Hi. W. 124 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. Light Sense. By Dr. P. Schiirhoff (Beth. Bot. Centralbl. xxiii, 1% Abth. Heft 1, pp. 14-26; 2 plates)—Finds in six species of Peperomia distinct evidence of a light-collecting apparatus. This consists, in some cases, of glandular hairs with the waterstoring cells which belong to them, or of secretory epidermis cells with the hypodermis cell, or of the basal cells of hairs with hypodermis cells. In one case there are papillary epidermis cells. The light is always reflected upon the chloroplast, sometimes in con- sequence of the shape of the cell whose upper convex wall functions as a lens, or in other cases because the light rays collected by the lens- shaped upper portion of the cell are dispersed by a crystal of calcium oxalate and so thrown upon the chloroplasts. Whether these structures are intended merely to condense the light or are really rudimentary light organs like the ocelli of some of the lower animals remains an undecided question. If they are only light-condensers one would expect the chloroplasts to change position when the light is thrown upon them from below. 4t was found, by experiment, that they retain their position when the light is thrown on the under surface, which is rather in favour of the theory that they act as ocelli. The distribution of the crystals would seem to show that the stimalus, if any, is transferred by the prosenchymatous cells of the vascular bundles.—G. [. S.-H. Lonicera Giraldii (Bot.

By Ernst H. L. Krause in Strassburg (Beth. Bot. Centralbl., xxiv., Heft 1, pp. 6-52).—Under the title of ‘“ Lapathon and Patience’’ the author investigates the history of Rwmex patientia. His conclusions are as follows :— The Greeks from about 400 B.c. used a Rwmex which was eaten as a vegetable. This plant seems to have been Rumex graecus, which is no longer in cultivation, but wild plants are still collected and used as a vegetable. A polymorphous series of species nearly related to it still exist NOTES AND ABSTRACTS. 125 in the Near Hast, and a few of them (besides graecus) extend into the Balkans. About the first century of our era the Romans obtained this vegetable from Greece, but even in the Middle Ages its cultivation had been abandoned, though a tradition of it still existed. The form cultivated in the Netherlands (which escaped the thorough destruction of the lands of the Allemanni during the barbarian invasions) is not Rwmex graecus but B. patientia, which may be a hybrid between the former and some wild species (perhaps Ff. crispus). This is very like the older cultivated plant, but better suited to a European climate. In the beginning of the sixteenth century the Franciscan monks used the roots of Ff. patientia instead of rhubarb, and cultivated it in the monastery gardens. So it came into gardens and into botanical hands. It was soon found to be unsuited for medicinal purposes. &. alpinus was used by the apothecaries for alonger period. In England it has either remained over from ancient times or been introduced. It has been eaten as a spinach since the seventeenth century, and has been distributed to many countries. G. F.

Gimingham, A.I.C.—The following experiment with nitro-bacterine was carried out at Wye College in 1908. _ The crops chosen were three varieties of ordinary garden peas and one of broad beans. The object of the experiment was to discover whether the use of the inocculating material under ordinary conditions of culture resulted in an increased yield of marketable produce. ‘The experiment was carried out on two types of soil :— (1) A soil which had been previously well-trenched and manured, and was prepared and intended for vegetable culture. (2) A very poor thin soil, just overlying the chalk and very deficient in organic matter. This was dug over just before sowing. In the case of soil (1) it was hardly to be expected that much good would result from inoculation unless the bacteria introduced should prove of much greater virulence than those already present in the soil; for in this case there was a fair amount of nitrogen present in the soil, and, moreover, peas had recently been grown there with success. Soil (2), however, seemed to be just the type of soil on which inoculation should prove of value. No leguminous crop had been grown 126 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. there for many years, and there was extremely little organic matter present ; moreover, lime and the necessary mineral foods were present in sufficient quantity. It would seem to fulfil the conditions mentioned on p. 10 of Professor Bottomley’s “ Seed and Soil Inoculation,’ under which inoculation is stated to be necessary. No manures were used in connection with the trial. On each type of soil four rows of each variety were sown, each row being 21 feet long, and in every case a row sown with inoculated seed alternated with a row sown with untreated seed. Thus at the end of the experiment the weights of produce from two rows inoculated and two rows uninoculated of each variety were obtained. The varieties of peas employed were Carter’s ‘ Hight Weeks,’ ‘ Karly Morn,’ and ‘ Yorkshire Hero.’ The culture fluid was prepared in the laboratory with all care to prevent unnecessary contamination and precisely according to the directions given. The temperature was regulated correctly, and the liquid used for the inoculation of the seed as soon as it appeared sufficiently cloudy. The inoculation was performed by immersing each lot of seed, contained in a small muslin bag, into the liquid until thoroughly wet. The seed was then spread out in a cool shady place until quite dry and then planted, the same amount of seed being used for planting each row. At about the time of flowering plants here and there were taken up from corresponding rows, and their roots examined with regard to the formation of nodules. Apparently throughout, nodules were formed quite as abundantly on the uninoculated plants as on those inoculated. No differences were observable at any period between corresponding rows on the same ground, whether with regard to general growth or to the time of coming to maturity. The following tables give the results obtained, showing the total weight of pods from each row expressed in grams.

The weights of pods of the various rows of each variety show, indeed, remarkably little variation when it is remembered that a difference of 250 grams represents only about a handful of pods. There was no evidence to show that the slightest benefit had been obtained by the use of “ Nitro-bacterine”’ on either type of soil. The experiment was not on a large scale, but it indicates the kind of results to be expected from the use of this material under ordinary garden conditions in this country, and serves to confirm very many results obtained last summer.—C. 7’. G. Nuts, and their uses as food. By M. EH. Jaffa (U.S.A. Dept. Agr. Farm., Bull. 382 ; Oct. 1908).—Nuts are becoming more important as an article of food in the States. The native kinds are being improved, and foreign more widely cultivated. Nuts contain much fat and little water, the richest being the pecan— 70.7 per cent. of fat. The concentrated nature of the food is probably the reason for their being considered indigestible, and nut protein is slightly less digestible than that of meat, but this may be remedied by sufficient mastication. The water in nuts is 3 to 5 per cent. compared with 50 to 70 per cent. in meat. In general, nuts rich in protein and fat (brazil-nut, walnut, pecan and cocoa-nut) should he used with carbohydrate foods, such as bread, fruit, and green vegetables ; whereas those containing starch and sugar (chestnuts, &c.) should be eaten with meat, milk, cream and eggs. Nuts should be used as a staple food, and not merely as an addition to a hearty meal, but a nut and fruit diet is not recommended to the majority of mankind in place of the usual mixed diet. Oily nuts (not containing much starch) such as walnuts, almonds, filberts and brazil-nuts are useful in cases of diabetes, in the form of meal and flour. Nut butters (made from wasted peanuts) are much used by vegetarians, but they become rancid very soon. They are not identical with cocoa butter, or cocca-nut butter. Nut milk also differs from milk of cocoa-nut. The former made from a species of Canadium (seed of the Chinese olive) or Java almond, is used with some success as an emulsion or infants’ food. Many sweetmeats are made from nut products. Among the Tuscan peasants, chestnut flour is largely used in the form of porridge, cakes and bread. Acorns and horse-chestnuts are used by American Indians as food, after a preliminary process of leaching, to remove tannin and poisonous matters. Nuts are not economical as food compared with meat, with the exception of peanuts. Ten cents spent on these will purchase twice as much protein and six times the energy as the same amount spent on steak. Peanuts and dried beans supply more protein and energy than any other food. Amongst the less well-known ‘ nuts’ are the following :— Pinenuts—used in India, Italy and Southern Europe. 128 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. Lichi of China—a raisin-like fruit surrounded by a shell. Ginkgo of China (fruit of maidenhair tree)—nearly always used cooked. - Water chestnut of Asia (Z’vapa bispinosa)—seed shaped like two horns. Another water chestnut (Hleocharis tuberosa)—the corm or bulb is eaten. Seed of Chinese olive (Canarvwm)—oily but palatable. Another species of Canarvum (Java almond)— used to make emulsion for infants’ food. Candle-nut of Tropics—eaten after being thoroughly dried. Paradise-nut of South America. Cream-nut of South Africa. True ‘ Butternut’ of the Tropics. Cashew nut of the Tropics—must be roasted or is poisonous. Kingsland Chestnut. The Tabebuia from Zanzibar—seeds of a pumpkin-like fruit, oily and fairly palatable—is grown at Porto Rico.—C. ZH. L. Oak Disease (Oidium quereinum). By P. Heriot and L. Daniel (Le Jardin, vol. xxii. No. 517, p. 265; September 5, 1908).—In 1907-08 the oaks in France were attacked by a new pest, Ozdiwm quercinum, Thiénsen, which covers the young shoots with a white powder, consisting of ovoid spores (conidia) arranged in chains like those attributed to other Oidia. Up to September 1908 (date of article), the nature of the fungus had not been detected, but it seems probable that it is Microsphaera alni which abounds on oak-leaves in the United States, and has recently been reported from Geneva. Most species of Oak appear to be attacked by it, eg. Quercus sessiflora, pubescens, Toza, Ilex ; it has not yet been detected on Y. Suber, and coccifera. It is suggested that the disease may have originated in imported American oaks, but no observations have been made as to whether these were the first attacked. No adequate remedy is known, since it is impossible to cover a forest with sulphur like a vineyard. M. Daniel in an interesting note points out that the trees beset by the parasite are those which have been recently pollarded. In the Departments of which he writes this takes place every seven years. Some trees are completely pollarded, others are allowed to retain a central shoot, while those destined for the carpenter are not trimmed at all, but are allowed to develop freely. Now the fungus takes complete possession of trees lopped in the previous autumn, when the mutilated tissues contain a superabundance of water with no foliage to carry it off, while in proportion as new growth has been made and there is a return to the normal proportions of trunk and ‘boughs, the parasite has so much the less effect. The moral, according to M. Daniel, is obvious, and the remedy lies in more judicious foresting.—/’. A. W. Odontoglossum Leaf-spot. By M. C. Potter, M.A., F.L.S. (Gard.

O. macrodonta (syn. dentata) is an interesting plant, with crinkled thorny leaves like a Holly, and corymbs of single white flowers, inserted on long peduncles at the apex of the previous year’s growth. It is, however, only half-hardy. O. Hurybia Gunniana is comparatively hardy, and from its dwarf habit well suited for the rock garden. QO. Forsteri resembles O. macrodonta ; O.

Olive Culture, Dry-Land, in Northern Africa. By Thomas H.Kearney (U.S.A. Dept. Agr., Bur. Pl. Ind., Bull. 125, 1908 ; illustrated). —The use of trees as a drought-resisting crop in the dry lands of the States has up till now not been fully considered. The olive would ‘seem especially suitable for cultivation in the arid parts of California, Texas, and Arizona, to judge by the experience of the Old World. Although now practically a sandy desert, there is no doubt that Algeria and Tunis, before the Arab conquest, used to support large and flourishing popula- tions, whose wealth was derived in the early centuries of the Christian era from olive orchards and the production of oil. On the east coast olive culture never completely disappeared. Sfax, a flourishing seaport town, is surrounded by olive orchards to a distance of twenty or more miles, and contains many crushing mills, both native and European. The trees are set out about 70 feet apart each way, and pruned to admit the greatest amount of air and sunshine. The rainfall averages 9 inches a year, and is often less for a number of years in succession, so that irrigation is out of the question. The ground is kept quite clean when the trees are once in bearing. They begin to bear productively when about ten years old, increasing till twenty-five years, when they should be in full bearing, and with good treatment they so remain till fifty years, when they begin to decline. The average yield of oil from each tree in full bearing is about six | gallons. The best means of cultivation is that by contract with native proprietors, more economical and effectual than by European management. (The summary at end of pamphlet is instructive.)—C. H. L.

The eggs are shiny black, small and oval, and are to be found near the tips of the shoots. The aphides are at first of a dark green colour and later assume shades of pink and salmon. As with most aphides the forms hatched from the eggs are viviparous and produce numbers of young. After feeding on the leaves, &c., a large proportion of them acquire wings, and about the beginning of June (in Colorado) desert the peach for some of the other plants mentioned above, returning to the peach in September or October. Larvee of Syrphus flies and lace-wings and ladybirds prey on the aphides, and a small hymenopterous parasite destroys large numbers, while various birds feed upon them. The whole life history is very carefully outlined in the paper. The best results in controlling the pest were obtained by spraying with paraffin emulsion containing 5 per cent oil, Scalecide diluted 1 part to 20 parts cold water, cr tobacco decoction made by steeping 1 lb. of leaf tobacco or 2 lb. strong tobacco dust in 4 gallons water, just before the buds burst.’ It is recommended that all prunings should be burned.—F’.

The kernels of all these fruits are almost identical chemically with those of the sweet and bitter almonds, from which the almond oil of commerce 1s extracted, and as apricot stones from America are already exported abroad, and the extracted oil returned to America as pure almond cil, it is suggested that a native industry might be created, and the American demand for almond oil be supplied from the home orchards. — WES 16, Jak | Peach Die Back (Dep. Agr. N.Z., 16th Report, 1908, p. 112).—This disease was formerly attributed to Clasterosporium carpophilum ; but during studies of ‘Peach-scab’ it has become apparent that the fungus is identical with Corynewm Beyerinckit.

C. C. Peatmosses, Poisoning in. By Alfred Dachnowski (Bot. Gaz., xIvi., August 1908, pp. 180-143; with 6 figures).—The author has carried out some very interesting experiments on the toxic property of bogwater and bogsoil. He alludes to the great importance of the reactions upon habitat of the plants themselves. He collected samples of bogwater from a small “bog island ” (apparently a sphagnum and cottongrass swamp with an outer zone of alder, willow and Acer rubrum). archantr emmae Thea I haw 3 . uinae, Wheat, Indian corn, and several other plants were then grown in this bogwater after it had been variously treated. In one NOTES AND ABSTRACTS. 135 series the water was aerated, in another treated with dry calcium car- bonate, in another shaken with lampblack and filtered ; other sets were srown in the untreated bogwater and in an extract (4 gm. of bogsoil in 400 ccm. of distilled water). The experiments point to an injurious effect of some water-soluble substance in the bogwater which can be corrected by a method of aeration and by the use of calcium carbonate and lampblack. This is more marked in the sphagnum than in the maple-alder zone. Those plants which grew in the bogsoil extract were stunted in -root- formation, whilst their leaves were reduced in area, thicker, and with revolute margins—that is, distinctly xerophilous in character. This he explains as due to a reduced transpiration current in consequence of the poisonous character of the soil. The beneficial effect of small: doses of poisons comes out in some of the CaCO; and carbon-black solutions. Phaseolus seedlings grown in these closely resembled similar cultures in a ‘0001 strychnin or atropin sulphate solution. The width of the annual rings of wood in Acer rubrum, both from the ordinary woodlands and from the bog island zone already mentioned, was measured and tested biometrically. The mode was 3 mm. width from the bog island, and only 2 mm. from the ordinary woods. There were also very marked differences in mean, standard deviation, and coefficient of variability. The author seems to explain this also by the stimulation due ‘to minute proportions of poisonous solution in the bogwater. We find, however, the following sentence: “It may be readily ques- tioned whether part of the response arises from a deficiency of oxygen in the soil.’ This, of course, is the usual explanation of the peculiarities of peat-floras, but whether the author means by this sentence to admit this explanation or not is not particularly obvious.—G.

C. Potato, Brown Spots in Tuber. By W. J. Morse (U.S.A. Hap. Stn. Maine, Rept. 1907, pp. 318-3819 ; figs.).—Brown spots in the flesh of the potato are described. They were not apparently due to the presence of any fungi or bacteria. Some varieties appear to be more susceptible than others and the disease is looked upon as constitutional.—F'’. J. C. Potato Diseases in San Joaquin County, California. By W. A. Orton (U.S.A. Dep. Agr. Circ. 23; January, 1909).—The principal cause of the marked decrease in the yield of old potato land is the presence of a fungus disease, the wilt or dry rot (Fusarium oxysporum, Schlr.). The leaves assume a dull unhealthy appearance, with a rolling or curling of the margins. Gradually the tops wither or fall over; the diseased plants are easily pulled up, the roots partly dead and brittle. The fungus appears on them as a white or pink mould. When the underground portion of the stem is cut across, a pronounced brown discoloration is vi8ible. The brown stain is also found in the branches leading to the tubers. When the potatos are dug there is rarely any external evidence of disease. When infected potatos are stored in a warm temperature, dry rot soon appears.—M. O. C. Potato Experiments. (Jour. Dep. Agr. Vict. Sep. 1908, pp. 559- 575).—Immature potato seed in the case of ‘ Beauty of Hebron’ gave better results than were obtained from seed perfectly ripe and well matured. Change of seed from one district of the State to another did not, however, appear to affect the productiveness.—C. H. H. NOTES AND ABSTRACTS. T3Z Potato, Improvement of the. By Edward M. East (U.S.A. Exp. Stn., Illinois, Bull. 127, pp. 375-456).—The author considers that promising strains may perhaps be isolated from S. Commersonti, but not from any of the other wild species of potato. Even Commerson’s potato has so far not proved satisfactory in the United States. After a short discussion of the historical facts dealing with the introduction of the potato into Europe he points out that certain varieties do not produce flowers or else have infertile pollen which makes the introduction of new strains by crossing or raising from true seeds a difficult and uncertain process. Ninety per cent. of the modern United States crop is from varieties which have been produced by scientific breeders such as the late E.S. Carman. The differences in yield of these varieties is very great, varying from 18°7 (‘E. Six Weeks’) to 137-7 bushels (‘Green Mountain ’) of marketable tubers per acre. ‘The yield is in proportion to the growing season, provided that there is entire maturity before frost. In general, luxuriant vegetation is a sign of great productiveness, but in some varieties excessive vegetative growth is opposed to tuber formation. Rapid growth at first increases the yield, which is affected also by the weight of the seed-piece, by the amount of sunlight (darkened glass, clear glass, and open air as 1: 5: 11), by differences of age and of vigour in eyes when sprouted before planting, and by depth of planting. Drying the seed tubers, up to a loss of 20 per cent. moisture, also increases the yield. The author summarizes a large number of experiments dealing with the inheritance of characters when tubers are specially selected. Many of these experiments did not result in definite conclusions, for seasonal, climatic, and local soil conditions have “a tremendous effect.” It is, however, quite clear that tubers of a plant which has a large yield tend to be extremely productive. Thus in one variety large seed tubers of a productive mother plant gave a crop of 319g. Small seed tubers of the same plant gave 220 g., whilst large and small seed tubers of a small-yielding mother plant gave 113°3 g. and 80°9 g. respectively. The author also discusses the question of degeneration in potato varieties, and considers that there is no ‘‘old age’’ degeneracy, but that disease control is the most important point to consider. The quality of potatos for table use depends upon the anatomical structure. A thick cortical layer and small number of eyes are of advantage. Variations in table quality may be inherited, and can be used for the formation of new varieties. There are also variations in quality within one strain which are produced by the particular conditions under which the potatos have been grown. In composition (total nitrogenous matter) there is a surprising variability within one particular variety. Smaller, younger tubers are richer in nitrogen; but particular shapes or the number of eyes do not give any information as to the nitrogen content. Specific gravity tables are unsafe for the determination of the amount of starch. One tuber with specific gravity 1:090 contained 14°32 per cent. nitrogenous matter. Another (1-091 specific gravity) had only 7:39 per cent. There are also experimental results with regard to high protein 138 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. selection, amount of potassium chloride to the acre, and a useful biblio- graphy of 114 numbers.—G. F’. S.-H. Potato Leak (Potato Diseases). By W. A. Orton (U.S.A. Dep. Agr. Cire. 23; January, 1909).—Considerable loss is occasionally experienced from the rapid decay of potatos shortly after harvesting. This trouble is locally known by the term “leak ’’ or “melters.’”” The decay is due to the invasion of a fungus (Rhizopus nigricans). The fungus can enter only through wounds, and potatos injured by careless digging especially are attacked. The fungus is propagated by spores produced in large heads, or sporangia. It can grow on a variety of dead organic substances. It is known to cause decay in sweet potatos, apples, and pears. As a remedial measure avoid breaking the skin of the potato in handling; avoid piling newly dug potatos in large piles where they will “sweat.” Keep the potatos dry and well ventilated. WHS Ola Potato Plant Louse. (Nectarophora solamfolii). By EH. M. Patch (U.S.A. Hap. Str. Maine, Rept. 1907, pp. 2385-257 ; figs.) —This aphis is reported to have done great damage to potatos during recent years. The insect attacks the upper parts of the plants and causes the shrivelling of leaves, etc. A general account of the life cycle of aphides is given and details concerning field and insectary observations. The winter host of the species is at present unknown, but in captivity the insects fed on both shepherd’s purse and peas. It is regarded as impracticable to spray large areas of potatos with paraffin emulsion or, so far, to attack the pest through its winter host, but it is thought that clean cultivation including autumn ploughing and burning old potato haulm may have a beneficial effect. Various predaceous insects were found feeding upon it and parasitic insects and fungi which destroyed the insects wholesale were discovered. Technical descriptions of the various stages of the insect are Oahie apr COE Potato Seab. By W. J. Morse (U.S.A. Hxp. Stn.

A figure and description of the fumigating room is given. The quantity of formaldehyde gas recommended was found not to injure the eyes of the potato in any way except when the tubers were placed very near the generating pan or immediately above it. Lime was shown to increase the amount of scab materially thus: Treatment 1000 lb. lime 500 Ib. lime No lime Per cent. of scab on potato crop 49 27 tt Leds Potato-Seab, Prevention of. By W. J. Morse (U.S.A. Exp. Sin. Maine, Bull.141; 1907). Potato scab due to the fungus Oospora scabies is reported to be spreading. The scab fungus thrives best in an alkaline soil, and is favoured by the application of stable manure, wood ashes, air slaked or caustic lime, potash, ime and magnesia. It is more prevalent in heavy, moist soils than in light, dry ones. When the soil is once infected the danger of the disease attacking potatos placed in it remains for many years. It is recommended to green mantre such land as a partial check upon the disease before attempting to grow potatos upon it. When fresh soil is brought into cultivation care should be taken to plant only tubers free from scab, and these should be disinfected. The potatos may be soaked for 2 hours in a solution of 4 pint of formalin in 15 gallons of water, or in a solution made by dissolving 2 oz. of corrosive sublimate in 15 gallons of water for 15 hour. The seed tubers may also be disinfected by exposing them to formaldehyde gas in a close room for from 24 to 48 hours. The gas is generated by placing potassium permanganate in wide, flat-bottomed tin or galvanized basins 8 inches in height, and pouring over it formalin, closing the room at once. Twenty-three ounces of potassium permanganate and 3 pints of formalin are required to generate sufficient gas to fill 1000 cubic feet.— F’. J. C. Potato Scab, Varieties of. (Jour. Bd. Agr. xv. 10, January 1909 ; pp. 749-751 ; 2 plates)—Scab in potato may be due to (1) mechanical injury, due to the presence of ashes or sharp sand in the soil, or to a season of drought; (2) black scab due to the attacks of a fungus; (3) the attack of millipedes, especially Julws pulchellus; (4) the attack of the fungus Oospora scabies, which produces a scab superficially resembling that due to mechanical injury, but distinguished by the presence of the parasite; (5) the attack of the fungus Spongospora scabies.— Ff’. J. C. Potato Spraying. By W.J. Morse (U.S.A. Exp. Sin. Maine, Rept. 1907, pp. 287-304).—Relative results of spraying with standard Bordeaux mixture against the leaf diseases caused by Phytophthora infestans and Alternaria solam, as compared with dust sprays and spraying with Bordeaux substitute are reported, the results being greatly in favour of the Bordeaux mixture. Heavy and frequent spraying is shown to be more beneficial than frequent light spraying with Bordeaux, owing pro- bably to the better covering of the foliage by the former method. Spray- ing is often ineffectual in Maine because the spray is imperfectly distributed, the commencement of spraying is delayed too long, the 140 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. mixtures are improperly made, the quantities to be used being guessed - at, and the materials are mixed in the wrong way.—f’.

Maine, Rept. 1907, pp. 321-322).—Black spots on the surface of the tuber from the size of a small pea to half-inch in diameter, on which, when isolated, the fungus Phytophthora infestans developed. It is recom- mended that such tubers be not planted.—f’. J. C. Prairie Grass of Dakota, Floral Succession in the. By Le Roy Harris Harvey (Bot. Gaz., August 1908, pp. 81-109 ; with 3 figures).—The author describes three distinct stages, early spring, spring, and early summer (second week in June to end of July) in the flora of South-Kastern South Dakota. The climatic features of each of these successive flowering periods are given very fully, and the differences due to the various exposures and to the positions of the plants (asat the base or toward the crest of the ridges) are carefully distinguished. This area seems to show the steady colonization of part of the prairie by the forest flora of the south-eastern district, to which region, in the author’s opinion, it had been driven back during the glacial period. He considers that the “ Poa pratensis sod”’ is followed and occupied first by the Wolfberry shrub (Symphoricarpus occidentalis). This is the forerunner of Rhus glabra. These two shrubs are then dispossessed by Quercus macrocarpa and Ulmus fulva associations as the forest pushes out on the prairie. To the west and south-west of the region the plain or prairie type predominates and is of a more xerophytic character, becoming more and more arid and desert-like towards the west. The author does not think that the absence of trees on the natural prairie is due so much to forest fires, but rather to the lack of soil moisture, and to the dense sod, which make it difficult for the seeds of trees to germinate. Seedlings will also hardly resist the severity of their first winter. This paper is a very interesting one, although a few unusual technical terms are at first disheartening to non-botanical readers.

Forest Service, Cire. 151).—An account of the seasoning and grading of the timber of the Loblolly Pine, which has been found so useful for the making of cross-arms. The length of time required for air-seasoning depends largely on the character of the timber, atmospheric conditions, and the manner in which it is piled, all of which are fully described in this pamphlet. Several useful tables and illustrations of the best methods of piling cross-arms are also given. Ge bee Protoplasmic Streaming and Plasmolysis (Bot. Gaz. July 1908, pp. 50-56).—Miss Grace M.

No. 513, p. 204; July 5, 1908; 2 figs.)—The author finds this to be a much hardier plant than is generally supposed. It resists frost in an unheated greenhouse better than Pelargoniums, and may be planted out by the end of April. A month later it will be in full flower, and continues to bloom throughout the summer and autumn. Moreover, it will bear taking up and potting for exhibition at any moment, with subsequent replanting. The flower lends itself as readily as Salpiglossis or Mimulus to the production of new variations in colour. Already such varieties of the common fF. angulata as tugrina and rosea are in the market.—f’. A. W. Respiration, Rise of Temperature in. By George T. Pierce (Bot. Gaz., September 1908, pp. 193-202).—The author has found a new and efficient method of exhibiting the increased temperature in respiration and fermentation. This consists essentially in the employment of Dewar’s flasks or double-walled glass vessels with a vacuum between the two walls. (The 142 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. ordinary “Thermos” flasks depend upon the same principle.) He was — able to obtain with silvered flasks temperatures of 54°, 55° and 56° with living germinating peas, whilst the dead peas in control flasks only showed temperatures of 14° and 15°. The rise of temperature in the case of fermenting yeast was clearly shown, and also the increase in temperature or “fevered state ” of chopped cnions when compared with uninjured specimens. The efficiency of the individual Dewar’s flasks appears, however, to show considerable variation.—G. F’. S.-H. Ribes speciosum. By J. Mottet (Le Jardin, vol. xxii.

The small pendant flowers are characterized by very long stamens of a brilliant scarlet. The bush resembles Fuchsia Riccartoni closely, but its long sharp thorns distinguish it. It grows about 8 feet high, and flowers in May and June. Fruit a small red berry. In the autumn the foliage turns a rich crimson. Unfortunately, it is not hardy, and needs protection in winter. But in the south it grows to a great height, and is a striking ornament to the shrubbery.—F’.. A. W. Root, Geotropy of. (Beth. Bot.

September 1908, pp. 224-229)—The authors found that wheat seedlings when only watered with potash and other salts endured far NOTES AND ABSTRACTS. 148 greater concentrations of the salt than similar plants which were im- mersed in soil extracts. Even so lowa concentration as 700 parts in a million (of P,O;) proved injurious to those immersed, but when watered with a solution of 2,000 parts in a million the plants remained alive for three weeks. These results were found with plants growing in sterile quartz sand; but in ordinary soil, and especially in manured soil, still higher concentrations were tolerated. The absorption of phosphates in the soil varied (according to the system used for detection) from 20°5 to 27:2 parts in a million ina solution of 1,000 parts in a million, or in manured soil from 25°5 to 30:2 parts in a million. With a solution of 2,000 the absorption varied from 26 to 32°6 parts ina million. The absorption is a negligible quantity in the case of nitrate salts.—G. P’. S.-H. Saxifraga seardica (Bot.

The former is a native of Japan and throws out aérial roots which cling like Ivy. The deciduous leaves develop in April, and are opposite and cordiform, bright green above and white below. Flowers small and creamy-white, in dense corymbs. Large oval folioles of the purest white are superposed on the inflorescence, developing above the flowers, and form the chief attraction of the plant. Flowers May-June. Best propagated by cuttings.

Chasset (La Pomologie Francaise, March 1908, p. 85).—A ‘ Beurre Superfin Pear,’ shaded by a small house, has taken seventeen years before bearing any fruit ; a ‘Joséphine de Malines’ planted in the shade of a large tulip tree has never borne fruit. Two trees of the same varieties planted in the sun, pruned by the same gardener, regularly produce each year small crops of very good pears. The shade of the house and the tree has in this case evidently been the cause of sterility. Composition of the soil also affects fertility ; some soils lack phosphate of lime or potash and the trees bear after the necessary constituents have been supplied.—C. H. A. Shade Trees, The more important Insects affecting Ohio. — By J. S. Houser (Agr. Hup. St. Ohio, Bull. 194).—Contains information regarding the injurious woodland insects of Ohio, but particularly such as affect shade trees. The beautifully executed illustrations, some sixty in number, make the work still more valuable, for little difficulty will be found in recognizing a particular species from the pictures. What strikes one most in reading the book is the almost entire absence from the Ohio woods of the insect pests which trouble us so in this country. There are useful notes regarding spraying, preparing the various insecti- cides, and a table showing the common trees of New York State with relation to their liability to insect attack. The Ohio conditions do not vary to any great extent from those of New York.—A. D. W. Shrubs, A Wild Garden of. By W.

South Texan Prairie, Change of Vegetation on the. By O. F. Cook (U.S. Dept. Agr, Bur. Plant Industry, Cire. No. 14).— According to Mr. O. F. Cook, forest and swamp once occupied the gulf plains of Texas. Then followed a period of primitive Indian agriculture, 1a which forest stretches were cleared by fire. Such clearings remained under grass on account of the regular fires, which prevented the development of trees. So the land became open grassy prairies, where nomad hunters chased the great herds of buffaloes. In the early days of cattle ranching the fires were “ very besoms of destruction’’ but as the grazing became more thorough, the fires became of less importance and were kept under control. Sometimes it was found impossible to set fire to the old grass, especially in dry seasons. Then a new development began, for pioneer bushes of the Prosopis established themselves and formed ‘‘ open mesquite country ’’; upon these followed the invasion of Acacia Farnesiana, giant cacti, or “ oak runners,’’ and the forest was by means of these forerunners gradually reoccupying the land. But this will not happen, for the ranch-owners are selling their land to “truck ’’ farmers who find the land fertile and productive even though five to ten dollars an acre has to be paid for clearing away the bushes.

Irrigation and tillage are, however, transforming not only the appearance of the country but the character of the soil itself.—G. F. S.-H. Spenser, The Flowers of. By H. N. Ellacombe (Gard. Chron., No. 1,121, p. 898, June 30, 1908, and subsequent Nos.).—In this paper Canon Ellacombe gives an alphabetical list with interesting comments upon the flowers mentioned by the poet Spenser. The writer says: “ The account of the flowers does not profess to be a positive or scientific account, and the papers are rather an annotated index, or perhaps a concordance. I have quoted, but as shortly as possible, his allusion to each plant, and added short notes on those of them which seemed to require it.” —G. S. 8. Spraying Mixture. By Dr. Contant (Jowr. Soc. Nat. Hort. F'r., p. 122 ; February 1909). The author describes the process of manufacture of a spray fluid which he has found very effective, with the warning that, as it produces poisonous fumes during its preparation, it must be made out of doors. Once it is on the trees, however, a short exposure to the action of the air makes it quite innocuous to all but insect pests. A cauldron capable of holding 36 litres is raised on three bricks, 2 litres of water are put in it, and a fire is lighted underneath. When the water boils, 13 kilos. of quick-lime are put into the cauldron to slake. Water is then added little by little until the kettle is half full, and next 13 kilos. of flowers of sulphur are sifted in through a sieve, the’ mixture being stirred all the while to prevent its getting lumpy. When the sulphur is well mixed the whole is left to boil for about half an hour, and finally enough water is added to fill the cauldron. If there are many tree to dress, the mixture may be well stirred up and applied with a brush to trunk and branches during the winter, not later than the end of January, as it would burn the buds later. The mixture may also be left standing for six hours, when a yellow deposit, having a slight excess of lime, will have settled at the bottom, leaving a clear orange-coloured liquid above. This may be drawn off with a syringe into some vessel which may be corked up, as it spoils if exposed to the air. What Dr. Contant calls the “pure mixture’”’ or the deposit should be applied in the same way as already described, first scraping the lumps made by scale, to allow the poison to have its full effect. The clear liquor, on the other hand, may be used for spraying during spring and summer. When the leaves are young one part of liquor to ten parts of water is strong enough, later one in six parts may be used. For peaches, vines, roses, and beans, however, the weaker solution is always safer. For slugs among strawberries or salads, make holes from 15 to 20 centimetres deep among the plants, pour in a glassful of the mixture, and fill in the hole—WM. L. H. Statice arborescens. By H.

By the Duke of Bedford, K.G., and Spencer U. Pickering, F.R.S. (Woburn, Ninth Report, 1908, pp. 57-64). Stocks planted 24 inches deep weighed three times as much at the end of two years as similar stocks planted only 6 inches deep, new root systems in the former case having been formed from the stems at the optimum depth below the surface. Further investigations are being conducted. With crab stocks deep planting gave bad results, as indeed it would do with all worked trees.—A. P. Stocks, Fruit Tree. By C. T. Cole (Jour. Dep. Agr. Vict. August 1908).—Apples, in order to resist attack by woolly aphis (Schizoneura lanigera) are being grafted on ‘ Northern Spy’ and ‘ Winter Majetin,’ both stocks being immune to this pest; the ‘Northern Spy’ is the better stock. There are other blight-proof kinds of apples which could doubtless be used as stocks, but there is no need to increase the number except for special purposes. To prevent the stock from becoming weaker in its constitution from constantly working and re-working on the same variety, Mr. Cole has worked ‘ Majetin’ on ‘Spy’ and ‘ Maggs Seedling’ (another blight-proof kind, and robust in constitution) upon the ‘Spy,’ with the best results. For dwarf-apple culture the ‘Spy’ can be used, and the ‘French Paradise’ worked upon the ‘Spy,’ and the desired kind again worked upon the ‘French Paradise.’ There is now in this State, raised from seed there, a ‘ Paradise’ apple tree of dwarfing habit, free surface rooting properties, very easily propagated, and upon which the desired kinds may be worked direct. All kinds appear to thrive admirably upon it and it is quite blight-proof. Planters need to take care that their trees are worked sufficiently above the surface of the ground to prevent the scion from striking roots into the ground, and displacing the blight-proof stock, thus rendering the whole tree roots liable to become a blighted mass. Apricot.—The ‘Mussel’ plum stock is found best; ‘La France,’ a variety of the Myrobalan, is largely used, as it is easily propagated from cuttings and does not sucker. 148 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. Peach.—Stock raised from peach stones is generally the best ; selecting stones from medium sized mid-season varieties. In some districts almond makes the best stock. Plum.—The ‘Mussel’ plum stock is generally best; other varieties used include the ‘Julien,’ the seedling plum stock, also ‘la France’ a variety of the Myrobalan cherry plum, upon which Diamond and Orleans plums succeed well. Cherry.—The ‘Mazard’ and ‘Mahaleb’ stocks used in Kurope do not suit Victoria. ‘There, a small red cherry of the ‘Montmorency’ section, much like a ‘ Kentish,’ is found to be the best suited: it is a good cooking variety, and pleasant to eat; it acts as a dwarfing stock. Pear.—The stock most generally adapted for the pear is the seedling pear stock, raised from the hardiest known kinds.” Pear suckers are a bad stock. A small variety of quince, ‘Angers,’ is successful. As there are but very few kinds of pears that do well when worked directly upon this quince, it is usually necessary to double work, using first such kinds as ‘Beurré d’Amanlis,’ ‘Louise Bonne of Jersey’ or ‘ Beurré Diel’ upon the quince ; allowing them to make one growth, and then working upon these the desired sort, when perfect health and vigour will be attained.

The elm leaf-beetle (Galerucella luteola) is a serious pest of the English elm.

An unknown writer in 1845 correctly explained them as protuberances of the surrounding parenchyma cells into the cavities of the vessels. They may be the result of reduced tissue tension in the vessels owing to a wound, or to an abnormally low gas pressure caused in old wood by the cessation of water conduction. They sometimes close up or seal the vascular tissue, preventing loss of water, but in the case of climbing plants they may assist in the ascent of sap by diminishing the width of the vessels. Sometimes they act as ‘pumps’ pressing out carbonic acid into the sap and extracting from it nutritive salts. There is also a useful bibliography.—G. H. S.-E. Weight, Measurements of, Increase in. (Beth. Bot. Centralbl., xxiy., Erste Abth., Heft 1, pp. 45 et seq; with four figures.)—Dr. Hugo Hackenberg gives a series of tables dealing with the rate of increase in dry weight of Cannabis sativa and C. gigantea. The “substance quotient ”’ is obtained as follows: Specimens are taken at fixed intervals; the average dry weight at each period is then divided by that found at the preceding time of measurement. The seedlings one week old were 3:3 to 6°7 per cent. lighter in dry weight than the same number of seeds before planting. After this period there is an increase in dry weight, and the substance quotient varies from 1‘9 to 2°5. After the difference in sex is perceptible, the male plants increase more slowly than the females. In some of the male plants the weight was actually less after flowering (due to loss of leaves and pollen). The quotient curves seem to be independent of normal climatic fluctuations. The plants assimilated with the same regularity in spite of unfavourable conditions. But when a series of both male and female plants were grown in shade the quotients were distinctly lower in the shaded plants, and the dry weight was very much smaller than in the control sun-plants. The male plants were more maesously affected by shade than the female ones.—G. F’. S.-H. Woburn, Ninth Report, 1908. By the Duke of Bedford, K.G., and Spencer U.

His connexion with that Committee had continued without a break from its inception in 1868, and his acting-chairmanship from the time when, on his retirement from the Royal Gardens, Kew, Sir Joseph Hooker, K.C.V.O., F.R.S., F.L.8., V.M.H., still, happily, the Chairman of the Committee, was obliged to withdraw from taking an active part in its meetings. Dr. Masters always looked forward to the meetings of the Committee with pleasure and never grudged the time they took out of his busy life, | but maintained a keen and never-flagging interest inits work. His kindly | firmness, his ready sympathy, and his wide knowledge of botanical science, | always at the service of his colleagues, made him an ideal chairman and endeared him to all the members of that Committee. Not only was he possessed of wide knowledge but he had in a rare | degree the faculty of being able to impart to others the knowledge he possessed.

(Being the first ‘“‘ Masters Lecture.”’] HortTIcuLTURE and botany, practice and science, have always been most intimately connected. The philosophical mind of the student of nature is anxious to discover the laws which give the clue to an explanation of the phenomena he observes. From time immemorial the best way to find this clue has been the combination of the facts scattered over large fields of human knowledge. The florist looks for his information to botany, and the botanist enlarges his views by the study of horticultural observa- tions. Broad conceptions and far-reaching theories have been the result of this mutual co-operation and the doctrine of evolution is based on scientific inquiry as well as on the experience of plaht and animal breeders. Among the men who have worked along these philosophical lines of thought, our Society honours in the first place the name of Dr. Maxwell Tylden Masters. In commemoration of him these lectures have been instituted. The fact that the first of them has been committed to a botanist is a proof of our wish to continue his work along the same broad lines. Mainly through his influence English horticulture has developed itself on a sound scientific basis, whilst English botany has learned to avail itself of the many data afforded by horticultural practice. Physiology and morphology are both concerned in the elaboration of the combined field. Masters, however, preferred the morpholcgical side of the questions. He thoroughly appreciated the morphological ideas of Goethe and repeatedly pointed out the corroboration given to them by the observations of florists. Their bearing on the problems of the systematists, on the conception of species and varieties, and even on the broad lines of the evolution of the vegetable kingdom, were all equally dear to him. Almost unlimited were the facts at his command, many of them new to science or linking previously separated groups of phenomena. He not only recorded them for the use of others, but always carefully in- dicated the lines in which science might utilize them. His most prominent work in this field is his book on Vegetable Teratology. It is an inexhaustible source of information arranged in a clear and legical way. Teratology has always presented special attractions to students and amateurs. With a book like this in hand, they can easily estimate the importance of any apparently new case and investigate it in proportion to its relation to already described cases. In doing so, every florist can contribute his part to the development of the science, and no opportunity that offers itself needs to be lost through want of information. It is now exactly forty years since the Ray Society published this volume, At that time Darwin’s ideas on evolution were triumphing over MASTERS’ BOOK ON VEGETABLE TERATOLOGY. 155 their antagonists and widening their influence on all branches of bio- logical research. Masters warmly sympathized with them. He never allowed himself to digress upon the purely theoretical side of his deduc- tions from the collected facts, but was content with simply hinting at it. For the student in evolution these hints are most valuable; they clearly show that Masters was well aware of the significance of his facts and knew how to utilize them for the solution of great problems. We have only to follow his indications and to work them out in order to find the support teratology gives to the doctrine of evolution. J may here quote the concluding sentence of the book, which clearly shows the principles by which the author was guided. He says :— “That monstrosities so called may become the starting points of new forms is proved by the circumstance that, in many cases, the peculiarities are inherited, so that a new race is produced and perpetuated, and if a new race, why not a new species? The difference is only one of degree ”’ (p. 490). His “ Vegetable Teratology’ is the greatest work of his life. When still a young man he commenced collecting the material and compiling the literature of the subject. He did so at the suggestion of his friend, James Salter. From 1855 to 1868 he was Botanical Lecturer at St. George’s Hospital and for some years was Examiner in Botany at the University of London. It is especially during this time that he prepared his great work. At the age of twenty-four years (1857) he published his first contribution to the science of teratology in the “ Phytologist’ (Vol. I1.) It was succeeded by numerous articles on the same subject in various publications. The material rapidly increased and enabled him to give * An account of the principal deviations from the usual construction of plants,”’ as the second title of his book expresses it. It was a collection of facts, rather than the propounding of a theory, and met with universal acceptance. It is still unsurpassed and even the appearance of the work of Penzig could not make it superfluous. Penzig’s book is on a systematic basis, whereas Masters’ followed a morphological scheme. Shortly before finishing his classic work, in November 1865, Dr. Masters became Associate Editor of the “ Gardeners’ Chronicle.’’ From that moment he gave all his time and all his energy to this Journal and everyone knows how the influence of his mind, character and ability has been stamped upon its pages. His book was soon out of print, but it was impossible for him to prepareanewedition. The pages of the “ Chronicle” were full of contributions to his beloved science, but he found himself constrained to leave their application to another. This task has been taken up by a German botanist. Udo Dammer prepared and published a translation of Masters’ book, using Masters’ later material and aided therein by the author himself. Almost every page of the translation betrays the help of the author, and numerous additions and corrections enhance the importance of the work. New pictures from the “ Gardeners’ Chonicle ”’ give it additional weight. | The classification of malformations to be adopted in his book was a source of much consideration and trouble to the author. Of course a comparative study of the nature of the causes introducing the several changes would afford the most logical basis. But the material at hand M 2 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. did not satisfy this demand, and it was found impracticable to carry it out. In consequence of this, another plan was followed. The aim was to enable the reader to detect the kind of monstrosity he happens to have observed in nature, and to place in his hands all the information he wants in his study of such cases. The morphological point of view answered these requirements, and explanatory remarks, illustrative details, and a summary of the more important facts and conclusions accompany each chapter. The larger number of the cases described rested on personal observations of the author,and numerous figures, either from his sketches or from his preparations, illustrate the text. The main parts of the book describe the deviations from the ordinary type under four headings. These are: the arrangement of organs, their form and number and their size and structure. These four parts are divided into chapters according to the morphological principles. Union and separation of organs, increased and decreased number, changes of form, suppression of parts and hypertrophy, abortion and degeneration are some of the more important subdivisions. But, although the description of anomalies forms the bulk of the book, the influence of the philosophical mind of the author is seen everywhere. Teratology serves as an aid in the study of morphology in general, as well as in that of special groups of plants. It is often a more trustworthy guide in the solution of such problems than even the study of the development of organs. Teratology indicates the primitive structure of the flower in many groups of the higher plants; it implies the hypothesis of a prior simplicity of organization. The author lays great stress upon its bearings on systematic botany. Where broader considerations are concerned, teratology affords aid in speculations concerning the affinities and genea- logical descent of species, of genera and of larger groups. In many cases ordinary morphology is insufficient, but the study of anomalies may give the clue. The anomalies are not indeed, deviations from the common laws, but simply expressions of these laws within less narrow limits. They give indications of atavism as well as of progressive changes. Relationships, otherwise unsuspected, may be disclosed by them. Numerous are the contributions of this study to the philosophical conception of the conformation of plants or of the affinities existing between them. : % * 3% * * * * * * I shall now endeavour to give a short survey of the trend of the book, by making a selection from among its rich contents. We may begin with the chapter on metamorphy, or the change of form. The best known instance is that of the change of stamens into petals, which Masters calls their petalody. Our first example is afforded by the double flowers of the crane’s bill (fig. 36). Here the stamens are changed into petals, and all the different stages of this change can easily be found. The petal formation is brought about by the broadening of the filament and of the connective, the anther lobes being separated and attached to the margin of the band. While this increases in breadth, the anther lobes diminish in size, lose their contents and ultimately disappear. At the end the whole stamen is dilated into a petal of normal structure and size. Some flowers are rich, others poor, MASTERS’ BOOK ON VEGETABLE TERATOLOGY. 157 in these malformations. Sometimes one or two stamens are slightly affected, or the flower becomes semi-double or fully double. All the numerous intermediate forms between true petals and perfect stamens may be seen on the same plant, and not rarely a series of transitions of forms is observed in a single flower. From a careful study of numerous cases of petalody, Masters derives the conclusion that the homology of the floral organs is usually not so much with the entire leaf of a plant as with its sheath. Im the case before us, we may observe how the stamens, in dilating and assuming petaloid structure, at first produce those little appendices along their sides which evidently correspond to the stipules of green leaves. Masters then recalls the views of Goethe concerning the essential morphological identity of the various whorls of the flower and its corroboration in the frequent appearance of one organ in the guise of another. It would take us too long to follow him into all his arguments ; it is quite sufficient to state the fact, in order to indicate how the philo- sophical aspect of the phenomena observed was always uppermost in his mind. Double flowers, sometimes, have all their organs changed into petals, or rather refrain from producing anything save petals. In analysing the very heart of the flower, we find the same scheme repeated almost without limitation, more young petals being produced for development than the flower is able to display. Sometimes the axis of the flower is abnormally lengthened, as in Some instances of the double crowfoot (fig. 37) of our gardens, separating dense groups-of petals and producing the appearance of a series of superimposed flowers. At other times, the petals are equally distributed along a lengthened axis, as in the white lily. Petalody of the connective is seen in some forms of the double columbine (fig. 38), in which this part of the stamen forms a tubular petal or nectary. These nectaries are not rarely repeated, a single stamen producing a series of them, which seem to slide into one another. From petalody there is only one step to phyllody, or the change of floral organs into green bracts and leaves. It is an anomaly of very frequent occurrence. In the green rose all the parts of the flower have become small green leaves (fig. 39). The stamens show the same mal- formations as in ordinary double flowers, but the dilated parts are gre&, instead of having the colours of normal petals. The reduction of the flowers to sterile corollas, and even to simple coloured stalks, is seen in a very beautiful example, the feather hyacinth (fig. 40). In this case it is combined with an increased number and with their branching. The supernumerary pedicels are brightly coloured and attract insects, which, however, can find neither pollen nor honey in them. From the morphological point of view we may consider the absence of flowers as compensated for by the formation of brightly coloured modified pedicels. For the evolutionist they constitute an increase of the change which the species itself shows in comparison with its allies. lis special character is the little tuft of coloured, but sterile flowers on the summit of the spike; these organs are more or less reduced in size and organization, the more so the higher they are placed on the 158 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. tuft. The highest ones may be considered the prototype of the feather- like pedicels of the variety. Another instance of reduction of flowers is seen in a most curious abnormality in maize (fig. 41), which, from time to time, although very rarely, occurs in cultures of the normal sorts. All the flowers of the male spike are absent ; sometimes a small tuft of bracts or of little naked branches is seen at the top, but, often, even this is absent and the whcle spike is reduced to a single spindle. Here not only the absolute bulk of the inflorescence is diminished, but the whole form is altered and de- pauperated. It is therefore to be described as a case of degeneration. In the wheat-ear carnation also the flowers are absent, but replaced by green ears of little bracts (fig. 42). These bracts are the same as those which, in the ordinary carnation, are found at the base of the flower. Here they are arranged in alternating pairs, only a small number of such pairs protecting the lower part of the calyx of each flower. In the whéat-ear carnation there is an increase of the number of these bracts, so as to produce the appearance of ears. As the whole flower is sup- pressed the variety becomes sterile. This monstrosity can be multiplied and preserved by cuttings, but from a horticultural point of view there is, evidently, no use in doing so. On the other hand, many varieties of our garden carnations produce the wheat-ear plants, from time to time, and it is, perhaps, the most interesting instance of a species producing the same striking anomaly at irregular intervals of time. These wheat-ear carnations are sometimes seen to produce instances of reversion or atavism. In such cases the plant bears some normal flowers among the mass of green ears. Intermediate forms arise, con- stituting small or only partly developed flowers on the top of green ears, or better organized flowers with only some supernumerary pairs of bracts at their base. This is an instance of atavism, showing how the lost qualities of the species are not absolutely lost, but simply reduced to the latent condition. In this connexion, it is most interesting to see how the atavistic flowers on the wheat-ear plants do not reyert to the original wild type of the carnation, but to the special characters of the variety from which they sprang. In my own garden, a wheat-ear carnation reverted in this manner and produced beautifully doubled dark-brown flowers, which it had evidently inherited, though in latent condition, from its parent-variety. Here we recognize, in a most typical case, the bearing of the science of teratology on the doctrine of evolution. In cases of specific or generic atavisim, the parents to which a form reverts are not, of course, empirically known, and the whole explanation rests on an hypothesis. In the wheat- ear carnation, on the other hand, the parents from which they sprang are > always still in cultivation, and the reversions may be directly compared with them. The conception of atavism is no longer an hypothesis, but is supported by a complete set of facts and observations. One of the most curious instances of an hereditary anomaly is the Nepaul barley. It is a cultivated and constant variety, which has attracted the attention of many botanists. Masters gives a full description of it, with many figures, some of which are reproduced in fig. 48. In the ears of this plant, it is the outer palea which shows the deviation from aannenent ad ee eT ee eee en ee ee ee RL (gey abnd avs a7) “VOINOGHOIVHO SINHOA'T 40 UHMOT ST ‘SNENYEQ aIOIvEET JO aNY T¥WHON ao sNoIORS SQONVWOTVLAG V JO NOILOUS-SSOUDQ “ATI GLIHAA AHL 10 ANV ‘MNOLG “SSOUD 'SUTMOTY ATAAO(, ANY ‘AIAAOA~IWAG “LIONIG “sTVEO ONT WHE &o “(SIMOV "Yy) anouTELAg WHE wo ‘(SAOILVISY Sa TOONANVy) PNTONVHO XITVACVUD SNIWVEG “(ASNTLVUE WAINVUSED) TIrg S UNVUO LOOTMOUD NICUVH AHL JO SUEMOT YT AIGAOG ‘“AWONOTVING-—'")LE ‘Ply AHL 10 SUTMOT YT ATIACG HHL NI SNENVLY FHL TO AGOTVEN™— ge ‘p1g et et ee kl ce Rose ewe ereene ont to apo S at ota ae “SNAWVLG SLI TO SHALLOUNNO() UvindoAy, M WHOS JUVMC, Lowe GHG Lawl AHL AHL GNV ‘SUHMOTYA AIAA0”d HAI Tut £0 SHILGIUVA INTUaMITd—"Bg “PML ‘SLaTAVaT NaaUt) og, ‘(vINTIIN>y) FNTAWATO) OL DNISNVHO SNEWYLG SLI wO MNOS GNVY ASOY INECEC REED) MASTERS’ BOOK ON VEGETABLE TERATOLOGY. 159 the ordinary type. This lower scale, which in other varieties of barley bears the awn, here forms an inverted flower-bud upon its midrib. It ig three-lobed at the summit. The central lobe is oblong and hollow, form- ing a kind of hood and covered with hairs. In its cavity the super- numerary floret is developed. Ordinarily there is only one, and that is rudimentary, but sometimes two or three of them are seen, each belonging to one of the three lobes of the scale. The three lobes are to be considered as shortened awns or as a three- lobed appendix representing the awn. The length of these awns is highly variable, and this quality is perhaps the most striking in the variety. They often reach only 1-2 mm., or the majority may become longer and attain even one centimetre, while here and there, between them, longer ones are inserted, extending in some instances even as far as 3 cm. from the spike. Their transverse position, in such cases, is strikingly con- trasted with the ordinary erect position of the awns. The accidental flower arises at some distance beneath the summit of the scale on its middle vein. The development begins with the protrusion of a little adventitious scale and the flower itself is situated beneath this scale, protected by it, and the primary scale, and in this way turned upside down. ‘The stamens occur in varying numbers; typically there are three of them, but, often, only one or two are developed. The ovary is situated in the middle of the flower and in some instances it has been seen to ripen into a little seed. All these deviations conform to a single type, and it is very probable that all of them have originated in the manner of a single varietal mark. Their high degree of variability may then be compared with that of variegated leaves or of double flowers. Another case of an hereditary anomaly is that of the peloria of the ordinary foxglove (fig. 44). Rarely is a malformation an isolated pheno- menon ; almost always it is associated, from the operations of cause or effect, with some others. A change, slight in itself, often acquires impor- tance from its combination with other alterations. This is particularly well seen in the case of the peloriated foxglove. Fission of the corolla, petaloid stamens, supernumerary petals often transformed into narrow tubes and sometimes situated on the outside of the corolla, are some of the many secondary malformations. Increase of number is another, and this is perhaps the most striking feature of this variety. The corolla is enlarged, bordered by twelve or more lobes instead of the normal number of five, and the number of stamens is increased in the same way. Finally, proliferation adds to the complexity of the flower. Within its ovary, small green leaflets often take the place of the ovules; and after the fading away of the corolla, they grow and burst the ovary wall and protrude from it, forming a green tuft of bracts. In other cases, the axis of the peloric flowers elongates itself through the middle of the ovary and develops into a new spike with quite a number of normal flowers, some- times even producing at its summit another peloric structure which may then repeat all the anomalies. In different places in his book, Masters has pointed out the necessity of assuming an influence of two sets of causes on the development of monstrosities. One set is internal, the other external. Internal causes are those inherent in the organization of the plant. 160 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. They are, of course, the more important, but external agencies un- doubtedly play some part in bringing about these changes. Masters has given a full discussion of this question in the appendix on double flowers, but the peloric foxglove may also be cited as an example. The more so, as the influence of external causes is most easily studied in this case. Our best way is to compare the terminal flowers on the side branches of a plant, with the pelory at the summit of its main spike. On the weaker branches, the peloric flowers become more and more regular. They lose their association with other alterations and tend to become pentamerous. This, of course, would be the condition of a normal flower of the fox- glove, were it not for its irregular structure. Or, in other words, we may imagine the ancestors of the species as having had pentamerous and regular, instead of irregular, flowers. This philosophical conception is now seen to be supported by the abnormal flowers on the weakest branches. Here the corolla has lost only its symmetry. It is regularly cupshaped with five small, but equal, lobes. Inside there are five stamens of the same length and a normal ovary. In comparing side branches of different vigour, we can easily collect a whole series of transitional forms between the two extremes just described. The peloric foxglove is an hereditary variety. Its seeds have been on the market for more than half a century. It was made an object of botanical inquiry, for the first time, by the Dutch botanist, Vrolik, whose preparations may still be seen in the botanical museum of the University of Amsterdam. Spiral torsion is the subject of another of the chapters of Masters’ book. One of its most interesting instances is afforded by the twisted stems of the wild teasel (figs. 45 and 46,p). Such stems are met with in the field, from time to time, and from their seed I succeeded in starting an hereditary race. It is highly variable and may show the deviation, under appropriate cultivation, in all its individuals, but only part of them will succeed in twisting their main stem over the whole length. | In the normal stem of the teasel, the leaves are arranged in pairs, which alternate with one another and are separated by long and straight internodes, covered with longitudinal ribs. In the twisted stems, on the other hand, the internodes seem to be absent, and the leaves are arranged along a line, constituting a continuous band. This line spirally ascends the stem; its curves are low and numerous in the basal part, but soon become steeper, and not rarely even quite erect. In this case, all the leaves of the main part of the stem are seen to be directed to one side only, thereby giving an extraordinarily strange appearance. The spiral torsion of the stem corresponds with this arrangement of the leaves. The ribs, which are longitudinal in normal specimens, are themselves twisted. The direction of their spiral is opposite to that of the leaves. A similar twisting of the stem is, from time to time, met with in other plants, the leaves of which are arranged in pairs or in whorls. The horse-tail (fig. 46, c) and the cleavers (Galiwm Aparine) (fig. 46, B) afford the most common instances. Ordinarily, only a small part of their stem is spirally contorted, the lower and the upper parts being of normal (091 abnd aovf or) ‘SUVGT LAOULIM GNV ‘Saag SLOOHG CDLVY N LSOWTY WO MDIVNY H 4 OV IN LIM OL Caenh ZV rN TO AVELSNI TUIUALG-—' Tp er er erg MLO BE Mage mo) iL UNV OL ‘SHALOMMLOG "JA LO SHAMIGQ ALIN AA MaATq CHorm WH Ot ‘NASOWOD ‘IN AUVNIGUO SHG Get ot ‘(WASOWATA WASOWOD TUVOSAY) HENIOVAL, UMHLVa THT —' Op “PLT “AUT KUVNIGUO TO SLUVA PNIGNOdSHUUOO TH HLIM ‘SUMLSVIY UALAV ATIVE ‘SLATAMIGG GNV SUTMOT] 10 STIVITC “IGCIW AHL NI AWTUVE, 10 UV TVWUON V HLIM (WOLVOUNMIUL WadauoF) AWIUVG IAVaaN—'eP ‘Ply *NOILVIMV A. qaq HdOouHs NOISUMAUY ONIMOHS NUWIONdS Vo GHOIN AHL NO ‘(SALVOIdS SOTIXHAOAUVO SOHINVIC() NOMVNUVQ UVa-Lva HM—'SPp ‘PLA ieee, Fic. 44.—Two Prtortc Frowsers or Foxa@nuovE (DIGITALIS PURPUREA) ON THE SUMMITS OF SPIKES AND ONE (CUT OPEN TO SHOW THE FIVE STAMENS OF EQUAL LENGTH) FROM A SMALL SIDE BRANCH.

Other examples may be cited, and the ironwood, or Caswa- rina (fig. 46, A), which is in so many respects like the horse-tails, is sometimes seen, in our conservatories, to twist in the same way. Partial spiral torsions, of course, also occur in the teasel and often give rise to additional anomalies. Spiral torsion may be considered as a case of complicated atavism, caused mainly by the loss of the position of the leaves in pairs or in whorls. They return to the more primitive spiral arrangement. This is the main point, and all the other striking deviations may be considered as the mechanical consequences of this primary change. For the evolutionist, this change from whorls into the spiral condition gives proof of the development of the more specialized arrangement, from the undifferentiated, and more common, spiral arrangement. Laciniate leaves, in some instances, afford examples of correlation. This is a most interesting question, and one to which Masters has given much attention. It gives us an insight into the internal causes of monstrosities. The same anomaly may betray itself in different organs, provided they are homologous. Such is evidently the case with petals and leaves, and from this we may expect to find correlations in their anomalies. Laciniate leaves induce laciniate petals, and the corre- sponding variety of the ordinary bramble is one of the best known instances (fig. 47). Pitchers (fig. 48) are, ordinarily, rare abnormalities. In the Magnolia they repeat themselves regularly, but in other plants they are seen but once, or at long intervals only. Some of them are formed from one leaf, others from the two leaves of a pair; and still others from the leaflets of compound leaves, as in the clover. In the case of the lime-tree, individual trees occur which produce pitchers annually and in large numbers, and in the pitcher-plants they form a normal character for whole genera. Returning now to the abnormal structures of the flowers, two of which are quoted by Masters as giving proof of the importance of terato- logy for inquiries about the ancestral relations of plants: it is generally assumed that the gamopetalous plants have been derived from the poly- petalous groups. Authors may differ on the question whether this has occurred once or several times along the main lines of the pedigree of the plant kingdom. But the conception that free petals are the primitive condition, and that gamopetalous or monopetalous flowers owe their organization to a subsequent cohesion of the petals, may be regarded as universally recognized. From this point of view, the dialysis of a gamopetalous corolla has to be considered as a case of systematic atavism, as a reversion of a species of the higher group to the more primitive con- dition of older branches of the pedigree. The Rhododendron (fig. 49) is one of the instances, and it occurs among a group of gamopetalous plants which, curiously enough, include some polypetalous species, such as those of Ledwm and of Pyrola. Quite the reverse is the case with the perennial poppy. Some of its varieties are producing, from time to time flowers in which the petals are united by their margins, so as to form a large cup (fig. 50). Often the petals are fused together in this way along their whole extent, but in other flowers it is only more or less of their base in which they are so 162 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. united. It is an anomaly which may be used in speculations on the origin of gamopetaly in the vegetable kingdom. For, when gamopetaly arises as a variation among poppies, it evidently becomes probable that it may have arisen in the same way, in some long past geological epoch, and then have been the origin of the whole systematic group of gamopetalous families. Itis one of the most striking cases in which teratology explains systematic affinity. It shows clearly the relation of this science to mor- phology and taxonomy and it is, in a large measure, to the philosophical mind of Masters that the now almost universal acceptance of this relation is due. From the work, let us now turn to the man. With his high scientific attainments Masters combined a wonderful capacity, willingness and aptitude for instructing others. His whole career has been one of the most useful in horticultural history. The application of botanical science to gardening was the aim of his life. In return, he was able to collect numerous horticultural facts forming an inexhaustible source of information, especially for the student of practical evolution. His work for the “ Gardeners’ Chronicle’”’ brought him into close contact with every-day practice and enabled him to guide it on a broad scientific basis. He was a model for us all, and his example will remain for ever an incentive to our best efforts. At the end of this first lecture, let us bring him the tribute of our gratitude ! ‘(4) NIVaNVIg ‘(‘o'u) AMATO amy ‘(0) vinssvag ‘(%) VIII, ‘(s) viuvaantovg ‘(a) viuawumog ‘(W) VIIONDV], 40 SUMHOLIG —gp “PLT ‘ATANVAG AUVNIGUO AHL FO WMO ST GNV AVA V THDIU WHL OF, ‘SIVA ANV SUAVATT GUCIAIG Aaa oeel GHL ONIMOHS ‘(SALVINIOVI sodoy) FIAWVYG MLVINIOVT FHT —)p ‘Pl | \ % (-e91 abnd aonf of, } *“KddO dq TIVINNAY AUVNIGUO AHL AO WAMOTY V ANY (wanviTd -ONOW WOLVRLOVUYS WHAVAVG) AddOg CUTIVIAd-ANQ HALOS PL ‘STVLE Tay ATIVILALY { HiIM SYUMOTA GHOTL ATLL OL ‘ SUAMOT iT MTAod fO STIVEATCG Lay THL OF, “NOOLLNOd NOUGNUGOGONY —’6P “OL ROCK GARDENS, NATURAL AND ARTIFICIAL. 163 ROCK GARDENS, NATURAL AND ARTIFICIAL. By R. Lioyp Prazcer, B.EH., B.A., M.R.LA. (Substance of a lecture delivered March 22, 1909). OF late years the cultivation of alpines and rock-plants has been increasing in favour, so that now a piece of rock-work devoted to these inhabitants of the hills is almost a necessity in any garden where an attempt is made to minister to the needs of the various classes of plants deemed worthy of cultivation. While the majority of alpines are of the easiest culture, many of them need special treatment, and some few others are the despair of the gardener : no soil or situation seems to please them, and all the wiles of the most experienced grower are lavished on them in vain. I have spoken of alpines and rock plants, and it may be asked why these two classes of plants are grouped together. It might be said that the conditions under which they grow are widely different ; that the flowers which brave the frost and snow and storms of the elevated regions would differ al- together in their requirements from those which flourish on dry hot rocks in the plains. And this brings us at once to the question as to what are the special features of alpines and rock-plants, and why we award them special treatment in the garden. If we examine a series of plants whose home is on dry rocks or high mountains, a general similarity of form will be observed, and several peculiar features common to both groups will force themselves on our attention ;—their dwarf stature; their tendency to form close cushiony masses ; the frequency with which they display a dense covering of hair or felt, or a tendency to succulence; and the size and brilliancy of their short-stemmed flowers. And all these features are explained when we consider the conditions under which they live. Whether on lowland rocks or highland slopes, these plants suffer great exposure to wind, and tall or loose or straggling forms would be broken ; but dwarf bushy growths successfully weather the worst storm. Exposure to burning sun, also, is excellently met by a cushiony growth, with the roots well tucked in under a dense mass of stems and leaves. Again, in alpine regions the summer is very short. After the snow has passed away, there is no time for the formation of tall or elaborate stems. Within the space of perhaps three months, the whole cycle of growth—leaf, stem, flower, and fruit— must be performed ; and hence our characteristic alpines are close-growing things, with flowers nestling close down to the leaves. Next, guarding against drought is a very important matter for all plants which grow in dry places. Dry winds—whether the scorching winds that blow across Arizona deserts or the icy breezes of alpine regions— are especially dangerous to the proper fulfilment of the functions of leaves and stems, causing as they do an excessive loss of water from the surface of these organs. We find in alpines and rock-plants various devices for hindering undue loss of water. The general reduction of the surface, effected by the close 164 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. growth and small size of the plants, helps materially. The leaves are often very much reduced as regards area, and their surface is often rolled back upon itself, as in many grasses, heaths, &c. Here also we find the use of the dense covering of hair or felt referred to already, which forms a very effective barrier against the scorching rays of the sun. In the succulent plants we see the most elaborate system of protection against drought. The skin of the leaves and stems forms a very imper- vious coat, inside which a large reserve of water and food is stored up against periods of drought. In the size and brilliancy of the flowers of alpines we may imagine we see the effort of the plants to advertise them- selves during the brief period of their florescence to the comparatively few insects of the mountain solitudes, in order that their blossoms may be properly fertilized, and mature seed result. When we come to cultivate alpines and rock-plants in our gardens, we should remember the conditions under which they grow in their native homes. First of all, even in the case of those which live on wet rocks, drainage is perfect; and that is the sine qud non of a successful alpine garden—drainage, and always drainage. And not only main drainage, in the way of a general draining of the site, should it need it; but drainage for each plant, in the form of a light porous soil, with ledges and stony pockets. Then we must imitate the sunny and open positions in which they grow in nature, by avoiding overhanging trees or other too dense shade for our plants. The soil should be deep, too, with big blocks of stone, for many of our little alpines have yard-long roots, which they are accustomed to thrust far into the rock erevices, in search of food and moisture. Natural rock-gardens of course display a wide variety of conditions. In the Alps or on any similar mountain range a whole series of floras is met with, piled one over the other. Above the limit of cultivation the pine forests climb up the slope, giving shade and a rich humus soil for many very delightful flowers. Above this, sub-alpine bushes often again afford protection. Thence we emerge on the great grassy slopes, gay with a hundred beautiful alpine species—Primulas, Gentians, Soldanellas, and many others; while around and above are rocky scarps and precipices, the favoured home of innumerable alpines—Saxifrages, Sempervivums, Andro- saces, and so on. Arctic plants resemble in many ways those of alpine regions, and it used to be thought that these two peculiar floras were closely allied, and had acommon origin. It was held that when the Great Ice Age descended on our earth, and the polar ice-caps crept further and further southward, the polar vegetation was pushed southward over the plains before it ; then, when the ice at length retreated, some of the plants migrated again towards the Arctic regions, but others climbed instead into the mountains, finding there the conditions of cold and exposure to which they were accustomed. But an analysis of the Arctic and the alpine floras shows that as a matter of fact they have little in common as regards composi- tion. Some few species are found in both regions, but the two floras on the whole differ widely. We must look on the alpine flora as a type developed early in mountain regions, which has since, as mountain ranges have slowly arisen and passed away, migrated here and there, so that ROCK GARDENS, NATURAL AND ARTIFICIAL. 165 while some alpines are strictly limited in their distribution, many others have now a wide and discontinuous range. (The conditions under which Arctic planis exist, and the character of the Arctic flora, were then described). Let us choose, for close examination, a natural rock-garden which lies much nearer to our own doors than those of the Alps, but is yet much less known, though it presents problems quite as interesting as any of those furnished by the flora of the great mountain chains. As we stand in Connemara in the West of Ireland, and look southward across Galway Bay, we see the hills of Burren, in Co. Clare (fig. 51), rising gaunt and bare. Even at this distance it can be seen that these hills are grey instead of green. This is owing to the fact that soil or other covering is absent and the naked limestone rock lies open to the sky over many square miles. But light vegetable soil has by degrees accumulated in the pockets of the rock, and on the flat-shelves, so that every chink is decked with flowers, and this seeming desert forms valuable grazing land for sheep. The remarkable feature of its flora is the vast profusion in which a number of plants, which are usually alpine in their habitat, here occur right down to sea-level. And stranger still, mixed with these we find some plants of southern origin, which here occur further northward than in any other country in Kurope. The lecturer proceeded to describe the district and its flora, and showed a series of lantern slides of these plants growing in their native surroundings. Returning to the question of the cultivation of alpine plants, the best methods of building rock gardens and of planting, were discussed. The “‘nocket system ’’ was recommended as combining suitable conditions with ease and cheapness of construction: A series of lantern slides was shown illustrating rock gardens (fig. 52) in various parts of the British Islands, and their good and bad points were commented on. 166 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. SOME LESSONS FROM THE OBSERVATION OF ALPINE PLANTS IN THEIR NATIVE MOUNTAINS. By Mr. A. Cuurron-Brock, F.R.H.S. [Lecture delivered May 18.] It is possible to take an interest and delight in alpine plants from many different points of view, but no one, I believe, can take so keen an interest and delight in the spectacle of them growing in their native mountains ~ as the gardener who tries to grow them in the very different conditions of his own garden. There is a danger, of course, that he may be too narrowly horticultural, that he may overlook all the wonderful beauty of the pasture flowers, of the claret-coloured Columbines mixed with white Orchises, of the Globe flowers and Campanulas that he knows already well enough how to grow, and that he may not be content until he reaches those high places where are the Androsaces and Hritrichium nanum and where he will learn scarcely any secrets that can be applied to the condi- tions of the ordinary English garden. But if he has a natural pleasure in all beautiful flowers, and if he is not over-eager to learn what cannot be learnt, and if at the same time he knows something, when he goes to Switzerland, of the cultivation of alpine plants in England, then his delight and interest in the beauty all about him will be enormously increased by his practical interest in the question how he can _ best reproduce some of that beauty in his own garden. This is the question which, speaking as a gardener to gardeners, I propose to deal with to-day. My object, is—rather vaguely, I fear, and discursively,—to discuss what we can learn about the culture of alpine flowers from seeing them as they grow wild; and I will begin with a few words of warning about the manner in which an inexperienced gardener is likely to be misled if he thinks he can learn everything about alpine gardening in England from visiting the Alps in the flowering time. I believe that some of the worst mistakes in rock gardening, have come from a blind attempt to imitate natural conditions, without considering the inevitable differences between those conditions and any that can be provided in an English garden. I need scarcely say what those differences are ; they are only too well known to all who have tried to grow alpines in England. But we must always bear them in mind when we try to draw conclusions from observation of plants growing wild in Switzerland as to what they will need if they are to prosper in England. And the difficulty of the problem is increased by the fact that some plants are far more adaptable than others, and that only experience will tell us which plants are adaptable and which are not. Thus many higher Androsaces and Hritrichium nanum and Gentiana bavarica are not adaptable at all ; and no one can keep them alive for long in England. But Ranunculus glacialis, another very high alpine, and one that grows higher than Gentiana ALPINE PLANTS IN THEIR NATIVE MOUNTAINS. 167 bavarica, is more adaptable than a plant like Pyrola wniflora, which I have seen growing freely on the bank of a trench in a Swiss pasture only about 6,000 feet above the sea, so freely that if I had not happened to know something of its habits, I might have been tempted by its beauty to carry it home to a certain, if lingering, death in my rock garden. But, if one is in search of deceptive plants, one need not take a rare one like the Pyrola. There is the little Soldanella alpina, one of the commonest plants of the Alps. It grows everywhere, and you would think that it would be as easy to cultivate as Campanula pumila. Yet everyone knows that it is difficult to flower; and for this reason, that it first starts into growth with the snows melting all round it, and it needs the moisture produced by these to make it form its buds. If it begins to form them in the east winds of an English March they are likely to wither up before they can come out, and the only way to succeed with Soldanellas, at least in a dry Surrey garden, is to surround them in spring with moss that must be kept damp until the flowering time is over. Or take, again, the case of Gentiana verna, a plant even commoner, which grows in pastures, in the fissures of rocks, and even in the glades of pinewoods. You might suppose from its abundance in all positions that it would grow anyhow in your rock garden. In which case your plants would probably be dead within a couple of months of planting. For Gentiana verna is not an easy plant to grow, at least in a hot Surrey garden, for two very good reasons. The first is that, like Pyrola uniflora, it dislikes disturbance and is slow to make new roots when once it has been disturbed. Where it grows wild, it is, of course, never disturbed from the time when the seeds first germinate. But since it is difficult to raise from seed, most gardeners plant it in early spring; and then, being thus weakened by disturbance, it has to endure other conditions quite different from those which make it thrive in Switzerland. There when first it starts into growth and all during the flowering time it gets continued moisture from melting snows. In England it may experience droughts and east winds all through Marchand April; the consequence is that it makes no growth before the hot weather and dies in the first -heat of June. In Switzerland one often finds it growing where it must be bone dry in late summer. But then it has got vigour enough in the earlier part of the year to endure any amount of later drought. In England it will not endure any drought until it is well established, which will often take a couple of years; and even then it will not make the same growth in our springs as among the melting snows of its native country. Thus in England it must be always pro- tected against drought, and it is fatal to treat it as an ordinary rock plant. It needs a flat place low down in the rock garden that will catch all the rain that falls, and it needs watering in any hot dry weather. There are many other plants, such as the rock Primulas, Anemone alpina and Anemone sulphurea and the Alpenroses, which one finds growing in very dry places, but which will not endure the same drought in England. On a slope above Fionnay I walked for over an hour among Anemone sulphurea growing as thick as buttercups, and with flowers larger than the largest, of Anemone japonica. It was mixed at first with Myosotis alpestris and higher up with Gentiana verna and Gentiana acaulis. Already where the Anemones were finest and most abundant the 168 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY, ground was quite dry, for the season was the end of June; and by August in a hot summer it will be as dry as a Surrey heath.. Yet there were scarcely any rocks, and the moral is that these Anemones, having grown there from seed, could endure any amount of drought in the summer because they had been well-watered in the spring. From this I infer—and I think experience bears me out—that our first care should be to encourage vigorous growth in the more difficult alpines by careful watering in the spring. Until they are thoroughly established they must of course have care at all times. But when they are established and have grown well in the spring, they will endure a good deal of drought in the later part of the year. It is in winter and spring that our climate differs most from the climate of the Alps; and whatever we do we cannot altogether overcome the difference. We must therefore always bear it in mind when we try to learn anything about the culture of alpine plants in England from observing them wild in Switzerland. In particular we must not suppose that a plant which thrives without rocks in Switzerland will do so in England, or that natural arrangements of rock will always serve as a model for rock work in our gardens. In the higher valleys of the Alps you will often find the whole ground carpeted with alpine flowers, as if they were daisies and buttercups in an English meadow and with scarcely a rock among them. You will find Gentiana verna and Silene acaulis making a flowery turf together ; with Viola calcarata, Androsace obtusifolia, Primula farimosa, Hutchin- sia alpina, Ranunculus pyrenaeus, and Pinguicula vulgaris and alpina. It is sights such as this that tempt one to wild dreams of making the same kind of flowery turf in England. But it cannot be done; at least not in Surrey. With us Silene acaulis will not grow in the same spot as Primula farinosa, nor will Androsace obtusifolia flourish with the Pinguiculas. These high valleys suit all kinds of Alpine flowers, except the highest and most difficult, because they are frozen hard and covered with snow all the winter, while they are moist with melting snows almost until the snows fall again. Thus the plants in them need no rocks to protect them either from stagnant moisture in the dead months of the year or from drought when they are growing ; and the conditions suit them all alike, whether they cannot endure stagnant moisture in winter or drought in summer. But we cannot give them such condi- tions ; and the best we can do is to learn the peculiar weakness of each plant and make what provision we can for them. We cannot make a flowery turf of all these alpine plants in a valley without rocks; because in such a place we cannot have freedom both from stagnant moisture in winter and from drought in summer. We must therefore plan our alpine gardens with a great variety of aspects and with carefully built rockwork, so that we may suit the needs of each particular plant. There is nothing in the Alps so likely to mislead an inexperienced enthusiast as the arrangement, or want of arrangement, of the rocks. Some of the ugliest and most desolate rock gardens in this country are attempts to imitate the savage chaos of alpine boulders,ewhich is supposed to be favourable to plant life, because some difficult alpines are to be found growing in it at an elevation of 9,000 feet. Now we in our gardens (*89T abvd aovfo7,) “AUVITSD mere) ‘NaUIAG HHL #O SNAGAVD-WIOY TWHOLVN GAL NI 0 a Se ee ee Sone alien (VIVLTdOLN0 Sy AU ) s NAW NIVINAOJ FH, Tg! roa (691 end anf OF ) "NULSAS _,daLg,, AHL NO GHDNVUUV SHNOLG ‘SGNQOW OLNI do NMOUHL HIUVA WHE INV ‘TOVAMAS TVUENGD AHL MOTHE LOOT T MNOS SHLVd “ISNGdXa GNVY ATANOUL TO WOWININ VY HLIM GNLOAUWLSNOO NAQUVN-MOOY Y-—GG “OL s0\MOLAN ALPINE PLANTS IN THEIR NATIVE MOUNTAINS. 169 can provide an absurd and insignificant imitation of the chaos, but we cannot provide the elevation with the pure mountain air, the sustained winter frost and the constant summer moisture implied by it. If we strew our little boulders about at random on some dry slope of our gardens, a few stone-crops or seedling wall-fiowers will perhaps flourish among them; but most other plants will seize the first opportunity of dying ; and an imitation chaos in an English garden bare of vegetation is scarcely less ugly than a rubbish heap. It is useless to study the rock- work of Nature, unless you know what functions rocks ought to perform in your garden. Butif you know this, you can get many valuable hints from the Alps, both horticultural and aesthetic. The first of these is that all rocks shall be placed so that the roots of plants near them will be able to run under them and so get protection from drought in summer and from cold and damp in winter. I mention this elementary point because I have often seen in ambitious rock gardens the rocks driven perpendicularly down into the earth, in which position they are of no more use than on a wall. You will notice in the Alps that the finest specimens of alpine plants are to be found often in conditions not otherwise favourable, but at the edge of a great boulder which slants into the ground, so that their roots can run under it and get coolness and shelter as far as they are likely to penetrate ; and it is in the slanting fissures of huge rocks that many of the more difficult plants grow best and most abundantly. Therefore never place a rock without thinking of the plant that is to profit by it ; never consider rocks apart from roots, for the function of rocks in a rock garden is to protect roots and not to look rugged or picturesque. The next point of importance is to have your rocks as large as possible, so that they may sink a good distance into the soil and give continuous protection to deep rooting plants. We cannot, of course, have the giant boulders of the Alps; but it is where they root under these great boulders that alpine plants flourish best; and even those which flourish without rocks at all in their native mountains may need their protection in a hot Surrey garden. Silene acaulis, as I have said, is often a pasture plant in the high valleys ; but in Surrey if you are to give it as much sunshine as is needed to make it flower well, you should protect it from drought by planting it where its roots can run under a large rock. It is the same with so easy a plant as Dryas octopetala which grows everywhere in the Alps. I have seen the bottom of a valley carpeted with it, beautifully mixed with Gentiana verna. It also needs plenty of sun if it is to flower freely, but in hot gardens it will suffer from drought in a sunny place, unless its deep roots can run under a stone. So it is with Polygala Chamaebuzus, another very common plant in the Alps. Even there it varies much in quality, and the most beautiful plants, both in habit and in colour, are not those which grow straggling and wiry in the glades of a pine-wood, but the short tufts mixed, perhaps, with the brilliant Viola calcarata on a rocky and grassy slope. We should try to grow it thus, taking care to water it well until it is established and keeping the stalks short by layering them in stony soil. These are all plants that thrive best among rocks in England, and so is the beautiful Daphne Cneorum of the Southern Alps, which always grows thiekest and flowers best when it is continuously layered and not allowed to grow leggy. VOL. XXXV. N 170 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. Layering as applied to these mountain shrubs is not a purely artificial process. They are constantly, at least when they thrive best, being subjected to the same kind of treatment by nature, for in spring the melting snows carry earth and grit and stones down on to them; and there are some, such as Daphne Blagayana, which soon perish in our gardens unless we imitate this deposit with top-dressing. ‘Top-dressing is, indeed, one of the chief secrets in the culture of alpine plants, and there are some of them, such as most of the Primulas and Aster alpimus which grow out of the soil if they do not get it. No doubt they have this habit because they are used to the natural top dressing of their own mountain snows. They expect an annual deposit and rise up so that they may not be buried under it. But many other plants need this kind of enrichment to encourage them to make new growth in spring, and in the Alps where the snows have just melted you can often see them half buried under the rich gritty soil that has been carried down in the snow. I am convinced both from experience in England and from observation in Switzerland, that we do not, as a rule, have rich enough soil in our-rock gardens. There are some difficult plants, of course, which will only live in a soil mostly composed of stones and grit; but these are the exception; and even these prefer what little soil they want to contain a good deal of humus. But the great mass of alpine plants thrive in a soil as rich as it can be made with decayed vegetable matter. Some are even the better for a deep layer of well decayed manure from a spent hot bed. Those which need but little soil and thrive in a narrow fissure between rocks, yet like that soil to be good and deep, and all alpines like it to be continually enriched with top dressing. Speaking very generally, I may say that the soil of the Alps is usually a thick mass of decayed and decaying vegetable matter, more or less mixed with grit and utterly unlike the hot sandy stuff which many people think good enough for a rock garden. This vegetable enrichment usually goes very deep; and we need to give alpines in captivity every encouragement to root deeply. Therefore we should give them two or three feet at least of good soil and if this is enriched with yearly top dressings we shall not need to be always shifting our plants about. There are a few that make a rank growth in a rich soil, which rots away in the alternate rains and frosts of our winters, but these are usually rock plants from hotter climates than the Alps, plants like the Onosmas and Aethionemas; and special provision can be made for them. Most alpines get through the winter best when they have made vigorous growth in the summer, and the best protection against winter rot is not to grow them poorly, but to give them good drainage and a sunny open position free from any kind — of drip. You must not suppose that because a plant will thrive under the drip of an overhanging rock in Switzerland it will do the same in England. Ihave seen Ranunculus glacialis growing fast and strong in the most drippy places; but we must remember that 9,000 feet up there is no drip in such places in the winter when all moistureis frozen hard. Drip only comes with the sudden spring, and then the plants do not mind it. But perhaps the most obvious lesson one can learn from alpine flowers growing wild is that they thrive best when they grow close together. IT am not speaking of the highest and most difficult plants, such as the e ALPINE PLANTS IN THEIR NATIVE ‘MOUNTAINS. 171 Androsaces or Hritrichium nanum ; we can learn little about them except that they require conditions which we cannot possibly give them in England. Until some one discovers some new process of acclimatizing plants, we shall never make them thrive in our gardens. I am speaking of the innumerable plants that can be made to thrive, which grow sometimes in rocky fissures sometimes interwoven in a beautiful carpet in the short turf of the higher valleys, sometimes more sparesly in great banks of shale, sometimes among shrubs or in the glades of pine and larch-woods. But wherever they are, there is no bare earth round them, and the soil in which they grow is swarming, as a rule, with intertwined roots. Therefore our object, both for horticultural and aesthetic reasons, should be to have no bare spaces round them in our gardens ; a rock garden should show nothing but rocks and plants. Jam aware that there are considerable difficulties in doing this, especially at first starting. Plants must have room to grow, and it is just when they are likely to suffer most from bare spaces—that is to say, before they are well established—that there are likely to be bare spacesround them. We can protect them against some of the evils of bare spaces by surrounding them with chips of stone which will keep the soil moist and open. But our ideal should be to have the ground all covered with plants, which are more beautiful than chips of stone, and we should aim at this ideal from the first, both by providing rich soil in which the plants will grow quickly and by arranging them so that they may be good neighbours. It is this kind of arrangement that needs knowledge and experience to enforce and regulate any observations we may make in the Alps. For we must always remember, before we attempt to imitate the profusion and the happiest combinations of nature, that in a garden our aim is to eliminate the struggle for life which prevails everywhere in nature. Among the Alps you will see Gentiana verna struggling through the rampant trailers of Dryas octopetala. Nothing could be more beautiful, but you will be unwise to subject your Gentians to the same struggle in your garden, for they will certainly succumb to it sooner or later. Nor can you be sure, when you see plants in the Alps growing discreetly together, that they will be as good neighbours in England. For some alpine plants change their growth altogether in the lowlands and some do not. Alpine poppies and alpine toadflax are the tiniest things high up in the mountains, with flowers disproportionately large and amazingly bright. Grow them in rich soil in a lowland rock garden and they will be five times the size, losing altogether their alpine proportions of flower to leaf and some of their alpine brightness. You must therefore know the habit of plants in an English rock garden as well as their habits in the Alpsif you are to combine them safely together. But if you have this knowledge you can get an infinite number of suggestions for beautiful and safe combinations from any alpine Paradise of flowers. You will see Dryas octopetala interwoven with Globularia cordifolia, an exquisite contrast of lavender and cream ; and the Globularia is vigorous enough anywhere to hold its own against the Dryas. Thenif you have a large enough rock garden with cool northern slopes you can plant Anemone sulphurea with Myosotis alpestris, though neither will be as rich in colour as in the Alps. Suzlene acaulis will contrast well with Hutchinsia alpina, both liking a fairly N2 172 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. cool place, but the Silene must be well grown if it 1s not to be crowded out by the Hutchinsia at the start. One of the most beautiful and commonest combinations in the Alps is of Campanula barbata and St. Bruno’s lily. This needs a large rock garden if the plants are to be combined in any quantity, and they should be planted close together, as they do not spread. Both can be easily raised from seed, and both thrive in the same fairly cool and undrained positions. Then there is a wonderful mixture I have seen of Anemone alpina and Aquilegia alpina, a combination I despair of accomplishing, because, for some mysterious reason, the alpine columbine, which surpasses all others in beauty, deteriorates quickly in captivity, even when you can get it true. I have found it in abundance above Champery growing in the rocks of anorthern slope with the alpine anemone, but nurserymen never seem to have the true plant, and if you buy seed under that name it is pretty sure to turn out some variety of Aquilegia vulgaris. Yet the two species are quite distinct, and no one could ever for a moment mistake the alpine columbine for any other. The Swiss themselves prize it more than most of their flowers, and sometimes they cultivate it about the higher chalets. It is not a plant of very high altitudes, and ought to be easy enough both to grow and to obtain—at least from seed. But there is some mystery about it which, since it is the most beautiful of all alpine flowers, ought to be solved. I may note also that the only way to succeed with Anemone alpina and A. sulphurea is to sow fresh seed and to plant out the seedlings as soon as possible. They dislike nothing so much as disturbance, and a full grown plant of either will seldom get over it. Other combinations I may suggest are Dianthus alpinus and Saxifraga caesia, both of which like lime and a fairly cool place; or Dianthus alpimus and Campanula excisa, for the alpine pink-is a plant of the higher turf and likes its roots to be mixed with the roots of other plants, like so many other alpines. Campanula excisa has a bad reputation, but it can be raised easily from seed, and if planted out with little disturbance will send out its little suckers in all directions, mixing up with the Pink but not smothering it. I am convinced, too, that Gentiana verna likes to be mixed with other plants ; it is usually finest and most abundant in the turf, but many of its usual associates in the Alps will smother it in England, and it should be combined with small plants like Androsace lactea or A. obtusifolia. As for Gentiana acaulis, of which the two best forms I know are our Knglish cultivated Gentianella and the sky-blue variety called ‘ Caeles- tina,’ it can be combined with Dryas octopetala or with Polygala Chamaebucus, if the latter is kept low and given plenty of space. Then we can plant Silene alpestris with Viola calcarata or with Campanula pulla, when the two will intermix their suckers and make a beautiful combination. The alpine poppy goes well with the alpine aster as both thrive in flat stony places, and there the poppy, which is often a biennial or annual in our climate, will seed itself freely. In the Alps one sees plants growing in masses of one species, and one sees different species interwoven. In our rock gardens, we should aim at the same mixture of massing and combination ; and where we have masses or combinations of freely growing plants, we need not have too many rocks. Let there be a large rock for each plant to root under. and leave ALPINE PLANTS IN THEIR NATIVE MOUNTAINS. iS plenty of space between them for the plants to growin. They will cover the space in a year or so, if only the soil is rich. Again, observation in the Alps will teach us not to make our slopes too steep, for the flowers are usually most abundant in valleys or on gradual slopes. Many people seem to have the idea that a rock garden ought to look rugged and desolate. Therefore they pile rocks together on a steep slope. But the Alps are not all desolation ; and we cannot imitate the grandeur of their desolate places even in the largest rock garden. We should aim rather at imitating their flowery abundance, and we can do this best with gradual slopes and shallow valleys, especially if we have a light soil to start with. Where sharp drainage is necessary it can be supplied under the soil with rocks and bricks. That is far better than the drainage of a steep slope from which the rain always runs away. No doubt on heavy soil and in rainy places the pockets in which the more difficult alpines are grown must be sloping ; and of alpine gardening in such conditions I cannot speak, for Ihave no experience of it. These notes are made for those who have light soils and a sunny dry climate like my own. I fear they are rather dis- connected and inconclusive; my only excuse is that they are all from my own experience, which is still very incomplete. 174 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. THE BRITISH PANSIES. By Eric Drassuz, D.8e., F.L.S. [Read April 20, 1909.) A SPECIES may perhaps be best defined for general working purposes as “the unit of classification’’: that is to say, it consists of an assemblage of plants, incapable of being further subdivided into segregates, which breed “ true’’ and show characters sufficiently constant to enable them to stand as distinct forms. The pre-Linnean conception of a species seems to have been rather what we now call a “genus’’—a group of plants showing many features in common—for example, the clovers—but readily further separated with a little care into truly distinct forms with constant characters. Linnaeus set himself to deal with a heterogeneous and somewhat chaotic material, out of which it was his ambition to evolve some sort of order. Consider- ing the nature of the material upon which he had to work one cannot but wonder and admire at the magnitude and accuracy of his results. That in many instances he grouped two or even several forms together under one name is no cause for surprise—indeed, he himself was quite aware of this fact; what must occasion surprise is that in the vast majority of cases his conclusions have stood the test of time, and this in spite of the careful scrutiny of specialists in the various groups. That Linnaeus did not stay to split some of the more puzzling and critical groups into their ultimate species was due to the fact that he desired to cover the whole Vegetable Kingdom in his researches, and hence he left such groups to the discriminating examination of those of his successors who should devote their attention to small subdivisions of the Plant Kingdom. Thus it happens that in several cases the “ Linnean Species’ falls but little short of being a genus, including several closely allied species. This is very noticeably the case in Viola tricolor. A great reproach to which systematists have laid themselves open since the time of Linnaeus—particularly his earlier followers—is that they have followed too slavishly in his footsteps and have hesitated to question his conclusions by experiment. This charge, however, must not be brought against all systematists even of the past. Alexis Jordan in © 1546 (“Observations sur plusieurs Plantes nouvelles ou critiques de la France,’ Deuxiéme Fragment) very cogently states the case for further examination, and says that in his day systematists were very much inclined to assume that the last word on the question of species had been pronounced by Linnaeus. But as for himself, he tells us, he refused to adhere blindly to the old traditions, and as -the result of his work we are now in a position in several genera to realize clearly the composite nature of the “ Linnean Species.” His good work was carried on by Boreau and cthers, and is now being continued by many workers at home and abroad. THE BRITISH PANSIES. 175 This kind of work has been greeted in some quarters not merely with _ far less credit than it deserves, but with discouragement and often with unfounded scepticism. The objections have been of two kinds. The first, which is happily now becoming a matter of history only, is founded on a misconception of the true aim of classification, which was, and still is in some quarters, regarded merely as a convenient means of grouping species for purposes of reference. Hence any tampering with the units was looked upon somewhat in the light of an inconvenient and almost unjustifiable interference. This view of course needs but little refuta- tion, for classification is now generally recognized to be an attempt to express natural relationships, and not merely, or even primarily, a matter of convenience. ‘The second objection is far more serious. Doubt is often cast on the scientific accuracy of the observations recorded. Unfortu- nately this objection is only too often well founded. Nothing is more harmful to the cause of Systematic Botany than the unrestrained practice of making a “new variety” or a “new species’”’ out of a plant which may differ in some point or points from the general and typical form of the plant in question. Scientific research is as urgently necessary in Systematic as in other departments of Botanical Science. It is, however, unfortunate that the earnest and careful student should suffer so greatly from the obloquy deservedly heaped on the mere “ species- monger.” It is absolutely necessary that the very best available evidence should be sought for the correctness of the conclusions. This evidence must be derived from several sources. The plants must be observed year after year and as far as possible under different conditions. Careful and minute examination of their characters must be made for several genera- tions, and should be extended to plants taken from localities as widely separated as possible. This examination may best be accomplished by cultivating the plants in such a manner that strict control of the condi- tions is possible. These lines of work are usually sufficient to demon- strate the constancy or otherwise of the form in question. Valuable evidence may also be obtained by investigating the possibility of the occurrence of natural or artificial hybrids. Several years ago I was greatly impressed with the apparent multi- plicity of forms of wild Pansies met with in this country, and in my attempt to gain some knowledge of the work that had already been done _ on this group on the Continent I was greatly helped by Mr. E. G. Baker, F.L.5., of the: Natural History Museum, who at the time was paying considerable attention to these plants. I gladly take this opportunity of acknowledging his kindness. At first the prevalent scepticism on these matters possessed me to the full, and up to a certain point the more Pansies I saw the less did it appear that there was anything but a wide range of variation in a single (or at most two or three) species. Looking back on that period I now see that this unbelief was almost entirely due to the manner in which the Pansies in our large herbaria have been named, for there it seems that nearly every collector has had his own ideas of the species, and has paid but little regard to the ideas of the first describers, and, moreover, the lack of care in discriminating form from form has been truly remarkable. In consequence, plants covering almost the entire range of form met with in 176 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. wild Pansies appear under the same “ critical’? name. This, for instance, is particularly conspicuous in the case of Viola agrestis Jord., for many of the plants so named bear not the slightest resemblance to Jordan’s figure (Obs. Pt. 2). So hopeless a mass of confusion was most destructive of any ideas of distinctness in these plants. Observations in the field were then continued in many parts of England, with the result that the original scepticism, so greatly strengthened by the study of herbarium material, became shaken and finally gave way to a conviction that we have indeed, without the smallest Fic. 53.—Viona Liuoypit Jorp. 1 Flower; 2, a lower leaf; 3, an upper leaf; 4, 5, stipules. (Natural size.) doubt, a considerable number of totally distinct Pansies. This conviction was the result of observations which may be summarized very briefly as follows : Under the same conditions and side by side two or more forms may grow, e.g. V. agrestis Jord.and V. Lloydi Jord., at Norton ; V. polychroma Kerner and V. Lloydw Jord., at Eyam; V. Lloydu Jord. and V. derelicta Jord., at Linacre; V. ruralis Jord. and V. agrestis Jord., at Spital. Moreover, the distinguishing characters are constant under very different conditions. For example, V. rwralis Jord., a plant of rich soils, when grown in almost pure sand on the sandhills at Wallasey kept its general habit and i no way became merged in V.

These supposed hybrids are not themselves referable to any of the named forms, and they show characters quite unlike those found in the plants believed to be distinct species. It is impossible to enter here into a discussion of these characters, but they will be described fully elsewhere. The evidence for a hybrid origin is very strong and supports materially the argument for distinctness of the parent forms. 178 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. What has been the origin of the various species, an account of which is now to be given, does not greatly concern us here. They may be mutational in origin, but I do not believe that they are now being formed by frequent and repeated mutation. _ Quite apart from the inherent interest of the study of any constituent group of our native Flora, this method of study is of particular value in the case of such plants as the Pansies, when we recollect that our garden Pansies in all probability sprang from hybrids artificially induced between the larger wild species of the North of England. It is the object of the present paper to show what was the raw material upon which the first introducers of the Pansies as garden flowers could work. The British Pansies may be divided into four main groups. In the first group are placed the Pansies of the cultivated fields. These are generally annual plants, very leafy and with a large number of E Or Es Bie Ee Eee hon & ae Hed ™~, eo % Eee, { if aN in \y Ee : se x ee Ya \ le ~ ue ie ay cae J 5 St wey i ad ‘NX j Soe /| : os @ | = & < <2 }, % * oe Le wv: 4 & L & \ a = Ee LE > F lf . ee bo A ao > Y Ss 7 j Se SEsny at Ree = poet soe a j i y | é | 6 : j j a beg NK 5 , ~ \ 7 e, cs y ey \ oe BO Sia pay i € 4 j << N 2. \ SG Ser Fic. 64.—VioLaA ALPESTRIS JORD. 1 and 1a, Flower; 2, lower leaf; 3, intermediate leaf; 3a, upper leaf; 4, occa- sional forms of stipule; 5, stipule from intermediate leaf; 6, stipule from upper leaf. (Natural size.) flowers. They possess large and usually somewhat pinnately lobed stipules with a mid-lobe showing a general similarity to the leaf. The corolla-spur is short, not surpassing the appendages of the sepals, and is usually rather stout. Many of these plants are small-flowered, with petals but little longer than the sepals (or even much shorter) and the sepals are usually broad. Of these plants may be mentioned V. agrestis Jord., . V. ruralis Jord., V. derelicta Jord., V. segetalis Jord., and V. subtilis Jord. These, on account of their small and unattractive flowers may be neglected in a search for the origin of the cultivated Pansy. Others of this class, however, have large and very beautiful flowers. V. Lloydw Jord. (figs. 58, 54) is a large plant with blue and white (some- times yellow) flowers; the upper leaves are long and the stipules have a large, rather slender middle-lobe without much dentation, while the lateral lobes are smaller and more slender, and spring chiefly from near the base of the middle-lobe. This plant is common in many parts of THE BRITISH PANSIES. 179 Great Britain. In V. variata Jord. (figs. 55, 62) the flower varies in size, but when large is exceedingly handsome with blue, purple, and yellow coloration, and well worthy of cultivation. The habit is bushy and the leaves are much shorter than in V. Lloydit, while the division of the stipule is very different, the mid-lobe being shorter and rounder and less unlike the lateral-lobes, and the stipule as a whole tends to be palmate in form. V. cantiana mihi (figs. 56, 63) resembles V. variata in habit, but is smaller in all its parts and of a different texture, while the leaves and stipules are covered with very short rather stiff hairs. The figure appears far more like V. variata than does the actual plant, the texture and general relative size of the parts affording ready means of distinction. V.cantiana appears to be extremely rare in England, and hence perhaps would escape the notice of the early observers. V. Lloydu and V. variata, however, would offer excellent material for the horticul- turist. These plants tend to become at least subperennial, and when crossed with perennial forms would probably produce very useful garden plants. a MED o> fs ) SN L - jas t ; ese \ f ‘ x ‘ i = y- ' fi 5 & { LS é ~ ¥ \oee b= r. 4 Ez 3 ¢ ¢ SS 1 oe [| 7 ‘ae a: v1 \ F 2 - | Se gs | 4 | i Fic. 65.—VIoLA LEPIDA JORD. 1, Flower; 2, leaf from base of stem; 3, leaf from middle of stem; 4, stipule. (Natural size.) In the second group we find truly perennial Pansies mostly growing in uncultivated places in the uplands. They are characterized by generally possessing slender subterranean stems, the ends of which, or lateral branches from which, or both, may turn upwards and bear foliage leaves and flowers. The mid-lobe of the stipule is usually quite entire and not leaflike, and the stipule as a whole is palmate. The spur of the corolla is longer than in the plants of the last group, and extends beyond the sepaline appendages. ‘The sepals are narrow and shorter than the petals. The British species are described below. V. alpestris Jord. (figs. 57, 64) approaches V. variata very closely and has often been confused with it. It is a bushy plant of similar habit to variata, but differs in the longer petaline spur. It seems to torm a connecting link between this group and the last. The flowers are yellow and thus differ from the typical form of V. variata, but the latter may also possess yellow flowers, and it is such plants that have been confused with V. alpestris. Viola lepida Jord. (figs. 58, 65) is a plant with several flowering stems arising from the base and bearing particoloured flowers. The mid-lobe of the stipule is entire and not leafy. Viola polychroma 180 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. Kerner (figs. 59, 66) is our handsomest British Pansy. It grows in large clumps 12-18 inches in height and with many stems arising from the base. ‘The flowers are very large and brilliantly coloured with blue and yellow. ‘The stipules are palmate, with a larger but quite entire mid-lobe. This plant appears to be very rare in Kngland; indeed, I have hitherto only found it in Derbyshire. ‘There can be but little doubt that if found it would be seized upon for horticultural purposes, and, as we shall see presently, it is possible that one of the Pansies figured in “ Gerard’s Herbal”? in 1597 was polychroma. Viola Provostw Boreau (fig. 67) is a large branching Pansy with long internodes, stipules like those of polychroma, very long axillary peduncles and large yellow flowers. Our British plants differ from the Continental ones so named only in having broader leaves, a distinction the constancy of which has not been tested and on d prior, grounds seems too small and trifling to serve as a dis- tinctive character.

Pansy (figs. 60, 68), which seems to fall into this group more naturally than into the last. The internodes are long, the leaves are exceedingly narrow, and the whole plant has a slender and graceful appearance. The flowers are large and chiefly blue or purple in colour. The plant is sub- perennial or perennial. ‘The British Pansies referred to this species differ — im one or two important respects from the type, and perhaps should not be placed here. Passing now to the third group, we find it to consist of a set of upland Pansies with short and almost unbranched aerial stems, and under- ground stems of a perennial nature. The leaves are generally small with palmate stipules, and the flowers are large. Of these plants the best known is V. lutea Huds. (fig. 61), a plant growing abundantly on the limestone hills of Derbyshire and elsewhere and having one, or at most few, large yellow flowers on each plant. The flower is generally much longer from tip to tip than it is broad. This is known to be one of the plants used THE BRITISH PANSIES, 181 in the crosses which first gave rise to the garden Pansies. De Vries, indeed, says :—‘‘ The garden Pansies are a hybrid race, won by crossing V. tricolor with the large-flowered and bright yellow V. lutea. They combine, as everyone knows, in their wide range of varieties, the attributes of the latter with the peculiarities of the former’ (‘Species and Varieties ’’). There is a blue-flowered variety of this plant known as var. amoena Syme, often found growing with the yellow-flowered plant. The plant known as V. lutea var. multicaulis (fig. 58) was originally placed here. It has several long stems and the general habit of V. lepida, but the flowers are more like those of a small /utea, and may be yellow or parti-coloured. It falls most naturally into the last-mentioned group. . The fourth group of Pansies is that known as the Curtisw group, and is composed exclusively of plants growing on sandhills by the sea. The habit is generally bushy with long underground stems of similar nature 4 | Li “ Yi 4 g La (| Vp ? a j ‘i ro N i re i ~—- YS 5 ae at mm 4 y | i h 7 ) E Fy \: | \ | Fic. 67.—Vioua Provosti Boreau. 1, Flower; 2, leaf from middle of plant; 3, leaf from base of plant ; re 4, 5, and 6, stipules. (Natural size.) to those possessed by most sand-dune plants. As has been stated above, V. ruralis on the sandhills, while adapting itself slightly to the habit of a sand-dwelling plant, does not at all change its other characters in the direction of V. Curtis. As none of these plants have in any probability served as a stock whence the garden Pansies have arisen they will not be considered further here. =, It is interesting to’consider the Pansies described and figured by Gerard in his “‘ Herbal.’ In the first edition, published in 1597, he refers to a yellow and a tricoloured garden Pansy as quite distinct. He also mentions as wild forms, the Heartsease and the Upright Pansy, the Stony Hearts- ease and the Wild Pansy. Inspection of the very excellent figures leads to the conclusion that these Pansies may with some degree of certainty be referred as follows: the Heartsease is probably V. Lioydi; the Upright Heartsease looks like V. polychroma; the Wild Pansy is a degenerate garden escape and the Stony Heartsease probably a small-flowered V. 182 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. variata. In Johnson’s edition of Gerard’s “ Herbal’’ (1633) the same enumeration of forms and the same descriptions occur, but they are accompanied by different figures. They seem to represent the following Pansies: the Heartsease is apparently V. variata; the Upright Hearts- ease is apparently V. polychroma; the Wild Pansy is a degenerate garden escape; while the Stony Heartsease appears to be a small-flowered arvensis form. Thus it is quite evident that at this early date different forms of wild Pansies were recognized, and, so far as we can judge from the figures, for that time excellent, but not sufficiently critical to render definite identification possible, the following Pansies seem to have been known: V. Lloydit, V. variata, and (rather doubtfully) V. polychroma, all of which would serve as useful plants for crossing with V. lutea to produce garden stock. Fic. 68.—VIoLA DECLINATA WaLpstT. AND Kir. 1 and 1a, Flower; 2, leaf from middle of stem; 4, stipule. (Natural size.) In conclusion, it must be emphasized that it is of the utmost impor- tance to understand the differences between these apparently distinct species in case any further hybridizing experiments involving the use of wild pansies should be contemplated. To say that V. lutea was crossed with the wild Heartsease Pansy means nothing but confusion. Recent work on hybridizing has shown with the greatest certainty that two closely allied forms may give quite different results when crossed with a third form, and hence we must be perfectly sure of our units if the record of the results of hybridizing is to have any value. | If, then, it be urged that the study of ultimate species is of a hair- splitting and somewhat unworthy kind, the answer even from a merely utilitarian point of view is at once forthcoming: that unless we know our units we can never count on any success in repeating crosses for horticultural purposes. To the botanist the only necessary justification is that, if the investigation be carried out conscientiously, the results must be a real contribution to our knowledge of the Vegetable Kingdom. SOME OLD SUPERSTITIONS ABOUT TREES AND HERBS. 188 SOME OLD SUPERSTITIONS ABOUT TREES AND HERBS. By Rev. Professor G. Henstow, M.A., V.M.H. [Read June 8, 1909.] THe TREES OF KNOWLEDGE AND Lire.—Perhaps the oldest of all super- stitions about plants is seen in Tree Worship, which has been almost universal. It most probably arose from veneration for certain trees in each country which supplied the inhabitants with useful products. The tree then came to be the dwelling place of the deity, so that in pictures on the tombs in Egypt, &c., a human being representing the god or goddess is seen amidst the foliage of the tree.* The sacred trees were called in Babylonia “The Tree of Life’’ and the “ Tree of Knowledge.” A Persian ‘‘ paradise ’’ was an enclosed garden of trees and walks for the delectation of the king. Mrs. J. H. Philpot, in her work The Sacred Tree, says: ‘‘ The sacred books of the Parsis contain a very similar version [to that of Genesis.] The original human pair, Maschia and Maschidna, sprang from a tree in Heden, a delightful spot where grew hom or haoma, the marvellous tree of life, whose fruit imparted vigour and immortality. The woman, at the instance of Ahriman—the spirit of evil in the guise of a serpent—gave her husband fruit to eat and so led to their ruin.” On a Babylonian cylinder a palm tree stands between two figures preparing to pluck the fruit, while a serpent stands erect behind one of them. If the date-palm was the “ Tree of Knowledge”’ in Babylonia, it would seem that the vine was most probably the ‘‘ Tree of Life,’ though the date was latterly apparently also considered as a tree of life. “It was characteristic of the earliest period of Babylonia, and while its fruit seemed to be the stay and support of life, the wine made from dates made ‘glad the heart of man.’ Date-wine was largely used, not only in Babylonian medicine, but in the religious and magical ceremonies.” T Professor Sayce, alluding to the Cedar ¢ as a supposed tree of life, which he now thinks was an error, says :—‘‘ It was upon the heart or core of the cedar that the name of Ha, the god of wisdom, was inscribed. It was wisdom rather than life, the knowledge of the secrets of Heaven and the magical arts that benefit or injure, which the priesthood of Babylonia and the gods they worshipped kept jealously guarded. Only the initiated were allowed to taste of its fruit.”” He here means the soma or wine, the giver of eternal youth and immortality. | The date wonld thus seem to include characteristics of both the trees mentioned. But as the vine is equally abundant in Babylonia, there is reason to think that this may have stood for the Tree of Life in that country. _ * See the goddess Nutt in a Sycomore Fig Tree in “‘ The Sycomore Fig,” Jowr.

The vine is often depicted—though in a very conventional form— attached to a date-palm, and this may have perhaps assisted to combine the two. Macic.—Professor Sayce has shown most clearly how magic preceded religion ; magical texts belong to an earlier and non-religious period in Babylon. It was thought that any movement was a sign or proof that the object in motion had a spirit, as man himself can move because he is alive. All sicknesses, &c., were supposed to be caused by evil spirits, so that to cure them magic was resorted to; but, as Professor Sayce says, “receipts for the cure of diseases, which scarcely differ from those that would be prescribed to-day, are mingled with charms and spells in later periods. The sick man was given his choice between a scientific treat- ment and a recourse to the old system of the primitive medicine man.” * Hymns to deities were associated with spells. So was it in the Middle Ages, spells were often remnants of prayers in the fourteenth century in England. “Tt was the existence of disease which first called exorcists into being. The prevention and cure of disease is the main object of the magical texts and incantations. Disease was looked upon as possession by a malevolent spirit.” So is it to this day in the uncivilized world. But one need only go back to Anglo-Saxon days from the ninth to the eleventh century to find the same superstitions still existing. “Scientific medicine was being clouded over by the mystical philosophy and magic of the Orientals, &. The sound methods of treatment were being superseded by charms and incantations with misapplied religious rites.”’+ Thus history repeated itself. In the a books of Babylon, we find prayers to the Sun-god with requests to remove “whatever worketh evil in the body.” Professor Sayce observes that it is a “strange mixture of spiritual thought and the arts of the sorcerer. ... The hymns to the Sun-god were not yet emancipated from the magical beliefs and ceremonies in which they had their origin. ... They must have been used by a class of priests known as ‘Chanters’ or ‘Enchanters.’.. . . In many we have an alternating antiphonal service, portions of them being recited by the priest, the other portions by the worshipper.” t Coming down to much later days charms appear to have acquired a new use in themselves, and not as prayers, for the words “charms ”’ and “ incantations,’ derived from the Latin carmen a “song” and cantare to “sing,” imply their original meaning as soothing lullabies ; but they often degenerated into a long string of Latin words without any coherent sense. These being “ droned’’ over the patient in a subdued voice would have much the same effect as a soporific discourse. But this may have been only a superadded use. ‘The real and original object was to expel the evil spirit which caused the disease. Now, in the preceding, plants formed an important element. The following is a good example given by Dr. Payne of the Magic of Henbane. ‘Dig round the sacred herb Hyoscyamus before sunset with the thumb * Hibbert Lectures, 1887, p. 317. + English Medicine in the Anglo-Saxon Times, by Dr. T. F. Payne, pp. 57 &. +. { The Religions of Ancient Egypt and Babylonia, p. 417. SOME OLD SUPERSTITIONS ABOUT TREES AND HERBS. 185 and the medical (or third) finger, not touching the root, and address it in a solemn invocation—‘ Sacred herb, I bid thee, I bid thee, to-morrow I summon thee to the house of my patient to stop the rheum of his feet, I conjure thee by the great name of Jaoth, Sabaoth, the God who made the earth solid and the sea to stand still, &c., to be thyself the spirit and power of the earth, thy mother, and dry up the rheum of this man.’”’ It was dug up with the bone of a dead animal and hung round the neck of the gouty patient. A somewhat analogous charm is in a list of recipes of the fourteenth century. “For the Goute-caine”’ [probably for “ Sayne,”’ 2.e. healing] :— ‘‘Take the rote of ache [celery] and writte thereon iii words +ihs+xt+ dominus+and as long as he be rith [exactly fixed] on hym aboute his nekke, if he haue gode beleue on God, he salle neuere haue it more in alle his lyue.”” The idea of “ hanging ” the magical article received the name “Amulet ’”’ from the Arabian physicians ; it means “to suspend.”’ In these mere allusions to God, to Christ and to saints, we seem to see a degradation for the hymns sung to the deity, as the Sun-god, to counteract the evil influence of the disease-causing spirit. Some of the charms employed in gathering herbs were very quaint in Anglo-Saxon times. Thus we read :—‘‘ For much travelling overland, lest a man tire :—Let him take mugwood (Artenusia vulgaris) in his hand or put it in his shoe lest he should weary.”’ A most important thing was to name the patient when procuring the plant. Thus Pliny mentions the nettle as being a cure for ague; but the names of the sick man and his parents must be pronounced when it is pulledup. As a lullaby for the toothache the physician is ordered to “ Sing this for toothache after the sun hath gone down [probably as the patient was more likely to sleep then]: ‘Caio laio quaque voaque ofer saeloficia sleah mama wyrm.’ ‘Then name the man and his father, then say: ‘Lilumenne’ it acheth beyond everything: when it lieth low it cooleth: when on earth it burneth hottest: finis. Amen.” The words are unmeaning, but are corruptions probably of Latin and Greek originals. ‘‘Wyrm’’ refers to the idea that toothache was due to worms. ‘Thus a recipe of the fourteenth century reads as follows: “ For toothache of wurms :—Take hennebane-seede and leke-seed and poudre of encens, lay them on a tyl-ston hot glowying and make a pipe of latoun [metal] . . . and hold his mouth there ouer the ouerende that the eyre may in-to the sore tothe and that wil slen [slay] the wurmes and do away the ache.”’ : Another charm was to repeat the words “ Argidam, margidam, stur- gidam, seven times on a Tuesday or Thursday when the moon was waning.” This was because the moon’s influence was then slackening. The spirit of a disease was sometimes threatened by some scriptural name :—Thus for a quartan ague: “ Depart from the sick man, Solomon is after thee!’’ The following is a remedy which Mr. Caudle might have tried, to avoid any distress from his wife’s “‘lectures’’: ‘“ Taste at night fasting a radish; then the chatter cannot harm thee.” SIMILARS AND SIGNATURES, SYMPATHIES AND ANTIPATHIES.—These represent medical doctrines of long standing, and applied to inanimate objects as well as to animals and vegetables. Thus the spear of Achilles VOL. XXXV. O 186 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. was said to eure the wounds it made, the sight of a yellow bird would cure jaundice, and the yellow juice of the Celandine would be equally effective. This wild Hower is still to be found in hedges near villages, being probably naturalized and not native. Hippocrates maintained thatif Nature, when effecting a cure, showed certain peculiarities in the process, the physician should assist by means of drugs which brought on similar symptoms. Philosophers took a wider view; thus one “likes”’ a thing or person because they are “like” what appeals to us. The idea is embodied in proverbs, as “ Birds of a feather flock together,” “ Blood is thicker than water,” &c. Hence Lungwort (Pulmonaria officinalis) was a remedy for lung-diseases, because of the spotted character of the leaves. Soldiers wounded should drink a decoction of Polygonum. Persicaria, because of the reddish dark blotch on the leaves, which resembled blood. The leaves of the cyclamen have somewhat the shape of an ear; hence they were prescribed in aural complaints. Viper’s Bugloss, was a cure for the bite of a viper because the stem has spots like those on a viper’s back. It was thought by some that diseases might be compared to poisons, which may be driven out by “contraries”’ or drawn out by “similars.” Thus one wrote: “It is well known that if a venomous toad be dried and powdered, and the powder sprinkled on a poisoned wound, it will draw out the poison as a magnet draws iron, and the wound will heal ; similarly antimony is a poison, but if treated chemically it will acquire the power of drawing out poisons from the human body.”’ Correspondences are shown by “signatures.”” Thus, if a plant has a fiower of two colours, it has two virtues; if three, then it has three, &c. (Paracelsus). A decoction of a thistle, because it is spiny, is good for pains in the side. The leaves and kernels of the peach tree are useful, “for we see on the fruit of the peach, if it be pressed by the finger, a hollow place, so also severe wounds leave hollow places behind them.” A curious superstition resided in “ Sympathetic ointment.” This was made of moss from a skull which had been exposed to the air, oil of roses, linseed oil, and some other things; then if you can procure the weapon with which a man has been wounded having some of his blood upon it, and anoint it with the sympathetic ointment, the wound will heal of itself without pain, even though the patient be twenty miles off. This idea was firmly believed in in the sixteenth century ; but in 1592 it was strongly denounced as absurd by the great chemist and physician Andrew Libayius, who wrote: “I was carving a ham and cut my thumb to the bone. I sprinkled the wound with sugar, and bandaged it (without anointing the carving knife), and with that single dressing it healed completely in a short time.” Nevertheless the superstition flourished. ASTROLOGY AND MeEpicine.—It was said of old “No one can be a good physician who is not skilled in Astronomy.” It was thought that the planets caused illnesses by exhalations, as the sun by its excessive heat; hence there was no use trying to cure an astral disease while its star was in the ascendant. “The doctrine that the heavenly bodies, and particularly the signs of the zodiac, exert an influence on the human frame was held throughout the middle ages. In the sixteenth century astrological calendars were compiled to show the proper days and seasons in which alone medicine =) EAE AE Airy sy apd» SOME OLD SUPERSTITIONS ABOUT TREES AND HERBS. 187 could be given or venesection performed. Some forbade any medicines to be given when the moon was in the signs of the ram, the bull, or the he-goat, as they are ruminating animals... and all medicine would therefore tend to return to the mouth.”’ * The famous Herbal of Culpeper was published in 1653 and ran through many editions; two, a small and a large, are still issued from the press. It is called ‘‘ An Astrologo-Physical Discourse of the Vulgar Herbs of this Nation.”’ He does not always say why plants are under the dominion of the planets, but now and then he does give a reason, which, however, the intelligent reader of to-day will hardly consider sufficient. Thus in dealing with Henbane : “I wonder how astrologers could take on them to make this an herb of Jupiter ... The herb is, indeed, under the dominion of Saturn; and I will prove it by this argument. All the herbs which delight most to grow in Saturnine places are Saturnine herbs, and the Henbane delights most to grow in Saturnine places ... Scarce a ditch or a [manure heap] is to be found without it growing by it: ergo, it is an herb of Saturn.”’ I once went into a small herbalist’s shop, and, in conversation, asked why it was that so many drugs were put into one receipt; as in the fourteenth century there were upwards of fifty in some cases. The pro- prietor said there are two reasons; one was to secure the chance of one or two being effective ; but also, as to-day, people would not buy it if the prescription has not several put into one mixture! After all, are the ignorant poor of to-day, who insist on this, more to be pitied than the higher classes who think it is “unlucky” to be married in May? not knowing that this has descended from Rome because the Lemuria, or commemoration of the deceased, was held in that month ! * Medical History from the Earliest Times, by Withington, p. 251. 02 188 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. WATER-PLANTS. By F. W. Moors, A.L.S., V.M.H. [Read August 3, 1909.) “ Ars plants require water.’ This may seem a trite observation to start with. Everyone will naturally say, “ We know that.” Nevertheless a suitable supply of water is one of the great difficulties of plant growing, and one which gets far too little attention from careless cultivators. There is no more difficult operation in gardening, nor one which requires more thoughtful skill, than the proper watering of plants. It soon becomes evident that some plants require more water than others; that what is poison for one set of plants means happiness for another set. Even to the unobservant this becomes obvious in a hilly district. By the dusty road side on the higher levels plants flourish, restricted in growth, harsh in appearance ; even in cracks in dry walls plants grow. On descending to the flats, flats which in winter are occasionally covered with water for a considerable period, vegetation becomes ranker and more varied, and finally pools, ponds, or lakes appear in which plants also flourish. In my remarks on “ Water-plants ”’ I intend to include all plants which will grow in a saturated rooting-medium, and not merely plants which grow in water partially or completely submerged, thus including what are gene- rally known as bog plants. The term “bog plants”’ is not a very happy one, as it does not discriminate between peat and mud. In Ireland it is generally applied to peaty swamps in which vegetation is sparse and rather limited, whereas in mud bogs the vegetation is more varied. I consider that any plant which will grow in water or in the saturated margins of a pond, sometimes spreading into the water, and which can withstand being submerged for days, or even weeks, without injury, may be termed a “‘ water plant,’ just as appropriately as a plant which actually lives in the water. Hixperiments made at Glasnevin prove that the list of such plants is far more extensive than one would think. It includes many of the Primu- las, Irises, Trollius, Lobelias, and other subjects often grown in the herb- aceous borders. Not only do such plants survive after being submerged for some time, or even covered with a sheet of ice, but they flourish in a way one rarely sees under ordinary conditions. A list of plants which have been cultivated under such conditions, and which during the spring were covered with water for over a fortnight, part of the time quite frozen Over, is given at the end of this paper. | feel that some apology is due for introducing the subject of this lecture, as it is no new one to the members of our Society. Twenty- eight years ago, September 8, 1881, Mr. George Paul read a very in- teresting paper, entitled “ Hardy Water and Bog Plants,’ in which he described the water and bog gardens made by him, and gave a useful list of plants suitable for the purpose; and Professor Boulger on June 19, 1900, dealt with the morphological and physiological peculiarities of WATER-PLANTS. 189 aquatic plants, and with their origin; while on August 6, 1907, Mr. A. Bedford, of Gunnersbury House Gardens, lectured on Hardy Nymphaeas, and placed before your Society practically all the information available about this charming group of plants. There is no more attractive addition to any garden than a quiet pond with suitably planted margins, and its attractions continue from the opening of the marsh marigolds at the end of February to the early parts of October. There is a quiet happiness in the appearance of such a pool, or pond, on a hot summer day in full sunshine, which is fascinating and which defies comparison with any other part of the garden. It is only when the same scene is contemplated in winter that one fully recognizes how much we owe to waterside vegetation. When making a pond the supply of water has first to be taken into con- sideration, as without a regular supply, small or large, it is folly to make such a garden. If a pond with varied and graceful plants in and around it is inspiriting and beautiful, a dry mud bed with shrivelled vegetation is depressing and ugly ; hence a water garden should be made proportionate to the certain available supply of water, large or small. It is surprising what can be done with a small supply. A rushing cascade is quite unnecessary ; in fact it may be detrimental to the welfare of the plants, as quiet warm water seems conducive to the best results and to the most luxuriant growth and flowering. In choosing a situation there is little difficulty where a stream is available. A pond can be made in any flat place near it and a supply of water brought from the stream, but there must always be means to regulate this supply. If there be no stream and a supply of water is brought by pipes some care is required in selecting a site. Select as low-lying a part as possible, a natural depression if one can be found, where one can stand above the pond and look down on the plants. A pond on a high level with lower parts of the garden beneath it looks incongruous and out of place. Another point worthy of consideration is that when masonry and cement have to be used the pond should not be raised more than a few inches above the level of the ground. A raised pond, or rather tank, may give scope for architectural design, but it is very discouraging to a gardener, and how to cover the sides will be a puzzle to the end of the chapter. If built below the surface of the ground there should be double walls, an outer water-tight wall, and an inner perforated wall. The space between these walls can be filled with peat and mud, and then planted with some of the many beautiful subjects named in the list. It is a great mistake to make a pond too deep: 18 inches to 24 inches at the deepest points, sloping up to a few inches at the margins, is ample for all requirements. A layer of mud may be spread over the bottom, and the individual plants can be planted in flat baskets, or in pans. Now as to the plants themselves. We are not driven to the tropics for them. Among our native British plants are found some of the most beautiful, useful, and dainty for an outdoor water garden, for growing both in and around water. One naturally first turns to the water-lilies, and as a paper specially dealing with these has been read before the Royal Horticultural Society it would be superfluous for 190 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. me to go into them in detail. No praise given them has approached exaggeration. You can have them for all purposes: for the great lake, provided the water is not too deep ; for the large pond; for the tiny pool. For large water areas such sorts as Nymphaea Marliacea and its varieties, carnea, albida, and chromatella, N. atropurpurea, N. Glad- stoniana, N. colossea, and N. candidissima are excellent ; for very small ponds, N. pygmaea and N. pygmaea var. helvola, N. Laydekeri rosea prolifera, N. odorata minor, and perhaps N. Elliszana will be found suitable, as they are of very moderate dimensions, and grow in 12 inches of water. It is rather with their collective than with their individual merits I wish to deal. ‘The ordinary white native Nymphaea alba, dear to everyone, has its drawbacks. It is one of the earliest to flower, and itis the earliest to fade. It ceases flowering in July, and the leaves quickly turn yellow, so that by August a pond covered with its decaying leaves looks quite melancholy. In August the newer varieties are still gay and bright, and the leaves quite fresh, and flowering continues until October.. I have seen flower buds frozen into a sheet of ice which covered the pond in October. This is a great gain, and greatly enhances the value of Marliac’s race. The first water-lily to open at Glasnevin for several years has been the Swedish rosy variety of the common water-lily, N. alba var. rubra (N. ‘ Carpary’), but it has one disadvantage of going off early in the season. It is difficult to get it typical, and there are many very poor varieties in the market. Nymphaeas are not a class of plants which get their sustenance from water alone, as seems often to be supposed; they are in fact rather greedy, and where there is not a good supply of natural mud, pure cow manure, with no Straw or litter, is an excellent food for them. It can be rolled up into small balls and thrown round the crowns just as growth begins. Where there is plenty of space the several varieties of Nwphar may be planted in association with the water-lilies, but they must be so placed as not to encroach on them, as the Nuphars are vigorous and aggressive, and owing to their strong rhizomes and roots they are difficult to get rid of. By far the nicest Nuphar is N. advena. Its leaves are dark shining green, and stand well up out of the water,and the centre of the flower is dark red ; a good patch of it is both effective and pleasing. Other plants suitable for associating with Nymphaeas are Phragmites communis, Ranunculus Flammula, Aponogeton distachyon, Stratiotes aloides, Cladium Mariscus, Sagittaria, Richardia africana, and bulrush. A word of caution is necessary about some of these. The reed grass, Phragmites, and Ranunculus Flammula are apt to take possession of things if not kept in bounds, but their runners are easily caught and pulled out by a strong toothed rake. Why should a little labour and attention be grudged to water-plants ? We give it freely to the alpines and herbaceous plants and recognize that it is necessary. Of the other plants a word may be said in praise of Cladiwm Mariscus, and the common bulrush, as they break the even surface and give variety. The grey foliage and drooping inflorescences of Cladium are particularly attractive, and it is not a plant which spreads much. Richardia africana is perfectly hardy if it is planted in water about 12 inches deep, so that the crowns are covered by water and are thereby protected from frost. Many illustrations WATER-PLANTS. 191 have appeared in the horticultural journals of fine masses of this plant in the favourable climate of Cornwall, in which district its hardiness is never questiuned. I may add that I have personal knowledge of its being hardy in all parts of Ireland, north, south, east, and west. For planting in water, either associated with Nymphaeas or in patches by themselves, there are many plants of varied appearance and beauty, such as Hquisetums, Alisma, Sagittaria, Myriophyllum verticillatum, Carex stricta, Cyperus longus, C. vegetus, Aponogeton distachyon, Orontium aquaticum, Hottoma palustris, Typha latifolia, and T. angustifolia. It may be said that some of these are ordinary native plants; but are they on that account any the less beautiful, or are they unworthy of a place amongst other water-plants? Any one who has seen a happily grouped colony of Hquwisetum, Sagittaria, Alisma, and Hottonia with some of the flowering rush (Butomus) amongst them will have no hesitation as to their worthiness. Whether or not they are to be included depends on size of the pond to be dealt with and must be left to individual taste and discretion. However, none but the smallest pond should be without a clump of the stately giant mace reed, Typha latifolia, or its more delicate and graceful congener, 7. angustifolia. Among plants which may be planted at water level in the margins and allowed to spread out over the water, so as to hide the formal edge, are Menyanthes trifoliata, Calla palustris, Myosotis palustris, Comarum palustre, Veronica Beccabunga, Glyceria aquatica, and G. fluitans. The two last named should be planted only round large sheets of water, as their growth is very vigorous. In mild localities Parochetus communis is also excellent for this purpose. I have seen long trails of it covered with blue flowers floating on the water and waving about in the current in the little stream at Mount Usher, in which position it has survived several winters. For the swampy sides of lake, pond, or stream the choice of plants is extensive and varied, and their flowering season covers the greater part of a year. There are bright flowering plants from February to October, Calthas, Primulas, Irises, Spireeas, Orchids, Lobelias, globe flowers, and others. There are bamboos, rushes, sedges, grasses. There are ferns, such as Lastrea Thelypteris, Onoclea sensibilis, Osmunda regalis. There are giants such as Gunnera manicata, Petasites gigantea, Iris aurea, Iris orientalis, and Spiraea kamtschatica, and from these through every grade to pyegmies such as Parnassia, Primula, Lysimachia, Pinguicula grandt- flora, Gentians, Mimulus radicans, and others. In fact there are plants for all situations, for all seasons, and for all tastes. In making a bog garden adjoining a pond, heavy holding clay should be excavated to a depth of 12 to 15 inches and a layer of stones, or clinkers from a furnace, should be placed in the bottom. The bed should then be made with ordinary rough peat; peat of a quality unsuitable for potting material will be found good enough, and with this may be mixed old potting material, suchas that in which forced bulbs and ordinary greenhouse decora- tive plants have been grown, and where it can be obtained some refuse sphagnum from the orchid houses. Somegood clean cow manure should be incorporated. Small pillars of the original soil may be left standing which will act as supports for flat stones on which one can get about through 192 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. the plants. Where the natural soil is a light loam all these preparations are unnecessary, water-loving plants will flourish in it when thoroughly saturated, and only small portions need be excavated for the peat lovers. It must be remembered that if properly nourished many plants grow to be veritable giants in suitable wet situations. Jiris orientalis and I. aurea will grow from seven to eight feet high. Lobeha fulgens, L. splendens and L. cardinalis varieties, will grow over five feet high ; Spiraea kamtschatica and its beautiful rosy variety will grow eight to ten feet high. Senecio japonicus makes a very stately and handsome plant, and the fine varieties of Iris laevigata make grand clumps. Dwarf plants such as Do- decatheon, Trollius, Primula pulverulenta, P. sikkimensis, Orchis latifolia grow out of all recognition. For this good food is necessary, and I have found nothing to equal clean cow manure. It should be applied every spring when doing up the beds. A note of failures is generally a useful addition to any list of plants for special purposes, and I therefore give a list of plants which are frequently recommended for water and bog gardens in the open air, but which I have found repeatedly die out when planted in water, or in a bog, liable to be submerged for any considerable length of time. Arundo Donax, Miscanthus japonicus, Thalia dealbata, Myriophyllum proserpina- coides, Cypripedium spectabile, Gentiana asclepiadea, Valisneria spiralis, Hydrocleys Commersonu (or Limnocharis Humboldt), Phormium tenaz, Inatris spicata, Meconopsis, Spigeha marylandica, Sarracenias, Darling- tonias, Bamboos. Several of these are, however, perfectly hardy and will live and thrive in damp situations, not liable to be submerged for any length of time. It would take too long now to go in detail into indoor water-plants having given more time than I intended to the hardy section. There is, however, the same fascination about them, and they are even more interesting and quite as varied. I do not advise general cultivation of tropical species of Nymphaea for those who are not early risers, or who are not able to visit an aquatic plant house at dusk, as the majority of them only expand their flowers between 7 p.m. and 11 a.m. The flowers are closed during the day and frequently retire under the water. There is, however, a section which can be cultivated in an unheated house, in tubs or in shallow tanks, the flowers of which remain open all day and close at night. They are chiefly blue in colour, and are very attractive. Amongst the best of them are N. gigantea and its fine variety, N. gigantea Hud- sont, N. stellata and its varieties coerulea and scutifolia, N. zanzibarensis and its varieties, N. ‘Wm. Stone,’ and N. pulcherrima. The habit of growth of these exotic species of Nymphaea is quite different from that of our native species. They have instead of a rhizome a hard coated tuber to which they die down in winter. These tubers may be taken up about the end of October, rolled up in balls of mud, or in some old Sphagnum, and kept in quite a small space, provided they are safe from rats.

BEES IN RELATION TO GARDENING, 195 BEES IN RELATION TO GARDENING. By Wauter F. Rerp, F.1.C., F.C.S. (Vice-Chairman of the British Beekeepers’ Association). [Read August 17, 1909.] Many of the greatest advances of modern science have been due to the recognition of the fact that even the minutest organisms and particles of matter are fully as worthy of detailed study as the grosser units that could alone be investigated before the invention of the microscope. The utility of such study has been abundantly demonstrated by the discovery of the bacterial origin of disease, and the isolation of radium, which has revolu- tionized our views of matter itself. Botanists were among the first to recognize the importance of the infinitely little ; knowing how small a seed could produce even the largest tree they readily accepted the microscopic marvels that were listened to with incredulity by many of their contem- poraries. The discovery of the fertilization of flowers by means of pollen opened a new era for the horticulturist ; but it is only since the classical researches of Mendel have been appreciated at their true value that the reign of law has succeeded to the reign of chance in the improvement of those products of the vegetable world that are necessary for our existence. No sooner was it ascertained without doubt that pollen played a part in the production of some of our most important crops than a series of investigations into the methods of its distribution commenced, and these investigations are still by no means complete. It is established beyond doubt, especially through the patient researches of Darwin, not only that insects are concerned in the pollination of flowers, but that certain insects and flowers are adapted to each other in a most wonderful manner. He found that bees especially contributed very materially to the produc- tion of some of our most important crops; in fact, without their aid the seed would, in many cases, have been sown in vain. While all kinds of bees are useful to the agriculturist it is the hive bee in particular that is his greatest friend, yielding, as it does, useful products of its own in addition to its utility as a fertilizing agent. That the beneficent action of these little workers was not sooner realized was due in a large measure to the erroneous belief which prevailed as to the nature of the substance which bees could be seen to collect from the flowers. Until the middle of the eighteenth century the little pellets of pollen which bees bring into the hive were mistaken for wax. It was not then known that wax was secreted by the bees themselves in glands specially adapted for that purpose. That bees generally visit the same kind of flower on each flight had not escaped notice; Aristotle was aware of the fact more than two thousand years ago; but the important bearing of this habit on the fertilization of flowers has only recently been fully appreciated. 196 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. There are several ways in which the hive bee conveys the fertilizing pollen from one flower to another. and, in considering these we must recollect that it is the worker bee only that visits flowers. Neither queen | bee nor drones are ever seen on flowers; they are consumers of food and do not collect it. ‘The organs of the worker bee are specially adapted for the work it has to perform while the corresponding organs of the queen and drone are but partially developed. First in importance to the bee itself as a means of collecting pollen are the so-called pollen-baskets with which the hind-legs are furnished. It is upon these that the bee brings home the pollen that is one of the ingredients of the food upon which it feeds its young. The hairs upon the body and legs are, however, the first instruments used in detaching the pollen from the flower. If you observe a bee issuing from a flower in which pollen is plentiful you will notice that it hovers for a moment in the air, and that its legs are in rapid motion. They are collecting the pollen grains from the body hairs and packing them upon that portion of the hind legs that is specially adapted to receive and retain them. But the bee cannot itself reach all parts of its body and some pollen is sure to remain on the hair. The tongue of the bee is an organ of great importance from the point of view of the horticulturist, as it can convey pollen into flowers which are much too small to permit of the entrance of the insect itself. The tongue is even more densely clothed with hairs than the body, so that any pollen grains that may come into contact with it are caught andretained. Some flowers are visited by the bees for pollen alone, especially in the spring, but, whether it come for pollen or honey, the bee cannot avoid carrying out the duties which the flower requires in return for the nutriment given. The mutual advantages of this arrangement are very great. Where a plant is dependent upon the wind for fertilization an enormous quantity of pollen has to be produced, with a corresponding strain upon the plant, and yet the fertilization is so imperfect that in some cases, of which the date palm is a familiar instance, harvests cannot be relied upon without human assistance. It has been estimated that one maize plant will produce 50,000,000 grains of pollen. Compared with such figures the quantity of pollen that a single bee can carry may seem small; but the activity of the insect more than compensates for any deficiency in this direction. Estimates as to the number of blossoms a bee visits on each journey differ considerably ; but there is little doubt that it may amount to several thousands. While the pollen gathered by the bee is of primary importance to the flower itself the same does not appear to hold good with regard to the honey, which is certainly one source of attraction to bees. Some authors have considered that honey is secreted by flowers as a bribe for their useful visitors. But some plants, such as the laurel and the Jerusalem artichoke, have nectar glands upon their leaves, and these are frequented by bees and wasps without any apparent benefit to the plant. Although it is customary to speak of bees gathering honey from flowers, what they really collect is nectar, which differs both in chemical constitution and consistency from the honey that we get from the hive. The nectar extracted from the flowers is stored in a small bladder known as the honey sac in which it is subjected to a preliminary process of concentration. On arrival at the BEES IN RELATION TO GARDENING. 197 hive the contents of the honey sac are ejected into a cell in which a further process of ripening and concentration takes place. Until the honey is so concentrated that it will not ferment the bees do not cap the cells over, and the bee-keeper who extracts uncapped honey soon finds to his cost that he has still a lesson to learn from his bees. Whether the hive bee visits flowers for honey or pollen it invariably encounters some device by means of which it is deprived of a sufficient quantity of the latter to fertilize the flower. I use the term hive bee advisedly, because the humble bee is less conscientious and often refuses to pay the price that the flower has the right to demand from it. Its powerful jaws enable it to bite through the corolla of a flower and thus to reach the nectary without coming into contact with the pollen. Darwin states that he has seen whole fields of red clover treated in this way, and that in the neighbourhood of Bournemouth he did not succeed in finding a single flower of Hrica Tetralix that had not been perforated. Such is the demoralizing effect of the desire to acquire riches quickly that even the highly civilized hive bee will utilize the holes gnawed by the humble bee, and where these abound, it will fly straight to them, without even looking at the proper entrance to the flower. Where humble bees are plentiful, gardeners will frequently notice the blossoms of scarlet runner beans perforated at their base, but I have not myself noticed any diminution in the crop of beans in such cases. The devices by means of which flowers force bees to deliver up a portion of their load of pollen are ingenious in the extreme. They have been fully and ably described by Darwin, Miller and Lord Avebury. In the time available to-day only a few representative flowers can be dealt with ; but those illustrated each represent large and important families of plants. (About twenty lantern slides were shown, illustrating the various devices by means of which fertilization is effected by the bee, and cross- fertilization secured.) In order that I might demonstrate the effect of the absence or presence of bees on the crop of fruit I carried out a series of experiments this year and have photographed the results. Gooseberry, red currant and black currant bushes were enveloped in muslin before the blossoms opened and were thus protected from the visits of bees. These bushes were then compared with similar bushes in the same rows and grown under exactly the same conditions with the one exception of the muslin envelope. The illustration (fig. 69, c.) shows a protected gooseberry bush which yielded only six gooseberries. The two adjoining bushes (fig. 69, a and 69,8) yielded respectively 151 and 167 berries; they having been visited freely by bees from hives about fifteen yards distant. Two years ago I happened to photograph the same bush that was protected this year in order to show a friend who complained of the failure of his gooseberry crop that I had been more fortunate than he. The number of berries was nineteen when the photograph was taken (fig. 69, D) ; but a heavy toll had then been taken by the birds. The six berries on the protected bush were probably due to the presence of a raspberry beetle which was 198 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. enclosed in the muslin. These beetles frequently emerge before the blossoms of the raspberry are open and then feed on the pollen of the apple, strawberry, and gooseberry. The protected red currant bush (fig. 70,8) yielded a few currants, chiefly as single berries. In this case ants Fic. 69.—GoosEBERRY BUSHES. when open to insect visits. A and B, Open to insect visits; c, protected from insect visits; p, the same branch as c in a previous year crawled up the main stem and may havelfertilized some of the flowers, or the wind may have assisted in distributing the pollen. A similar bush in the same row had a heavy crop of currants but in the photograph (fig. 70,4) they have been somewhat thinned by the birds who commenced eating them before they were ripe. It is sometimes stated in the daily BEES IN RELATION TO GARDENING. 199 press that the depredations of birds are due to the lack of moisture and that the provision of a supply of water will protect the fruit. This year there was not a single day upon which a plentiful supply of water was not available at a distance of a few yards, but the depredations of the birds have been even worse than usual. Fic. 70.—ReEp Currant Busnes A, Open to insect visits; B, protected from insect visits. The isolation of the black currant bush by means of the muslin was almost complete, for only two berries appeared (fig. 71, B). In this case it was remarkable that the foliage of the protected bush was less fully developed than that of its neighbours. The adjoining black currant bushes gave an average yield (fig. 71, a). The influence of the hive bee in securing the proper fertilization of fruit trees is so generally known that the apathy of fruit growers in 200 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. applying this knowledge is somewhat remarkable. ‘Those who do so, however, have every reason to be satisfied with the result. Mr. R. Brown, of Somersham, Hunts, is a well-known fruit grower who some years ago was dissatisfied with the yield of fruit from his trees and, on the advice of a friend, procured some hives of bees as a remedy. The result far surpassed his expectations, for, in the ensuing year, his crop of bush fruit increased fourfold. Being desirous of ascertaining whether Mr. Brown’s subsequent experience agreed with his first results I communicated with him and he writes on August 10, as follows :— “JT am thoroughly convinced that bees are the chief factors in the fertilization of fruit blossoms, and the production of fruit both as regards quality as well as quantity. Living as I do right in the midst of a fruit srowing district and being an ardent bee-keeper as well as horticulturist IT have made this subject a special study and have not the slightest hesitation in affirming that where bees are kept, much better results obtain in the garden and orchard. In 1907 when we had a very cold spring and when bees could work only at brief intervals and at short distances from home, there was an abundance of fruit in three orchards close to my apiary of fifty stocks. I closely watched their movements and made a special point of noting the results, and can affirm that, with the exception of these three orchards in the immediate vicinity of the apiary there was scarcely any fruit at all in this district. “This year, the weather being favourable at brief intervals for the bees to work, I have got the heaviest crop of apples I have ever had, and up to the present I have gathered 150 bushels off two acres, comprising the varieties Ecklinyille, Peasgocd’s Nonesuch, Beauty of Bath, Julian, June- eating, &c., being only a first picking, and scarcely half the crops. This is a Season when apples are quite scarce in our district !”’ This favourable testimony of a practical fruit grower might be amplified by the remark that Mr. Brown obtains a large quantity of excellent honey from his hives. Mr. T. W. Cowan, chairman of the British Bee-keepers’ Association, one of our highest authorities on apiculture, has long advocated the keeping of bees as a most efficient aid to the horticulturist. He has been good enough to send me two instances of the benefit derived from the introduction of bees which I will give you in his own words :— “Some years ago Lord Sudeley started fruit orchards at Toddington, and for some time they were quite unproductive ; in fact it was a question of giving them up. It was suggested that bees would be of use, and a Scotch bee-keeper was engaged to take charge of an apiary on the spot. The result was that the fruit trees very soon showed the difference and became remunerative. The trial was so successful that the orchards were enlarged, and a large jam factory was established to preserve the fruit. ‘There were 200 colonies in this case assisting the fruit grower which turned an unproductive orchard into a very productive one. ‘Another example is in California. I happened to be visiting Mr. Butler of Penryn, California, and he showed me over his ranch, where he had forty acres of peach trees. He complained that the eurly Alexander peach, which is a very good one, was a very shy bearer; in fact he said that it was such a poor bearer that he intended to grub up all the trees BEES IN RELATION TO GARDENING. 201 and replace them with Hale’s Early. The trees were a fine sight, some fifteen to twenty feet in diameter, and as they were in full flower they made a grand show. We examined the trees, and I noticed that there were no bees about; in fact, looking at a number of trees I only occasionally saw a wild bee. It at once struck me that it was the want of bees that was the difficulty, and that perhaps if there were plenty of them the trees might bear better. I asked how far away was the nearest Fic. 71.—Buack Currant BUSHES A, Open to insect visits; B, protected from insect visits. bee- keeper, and was told five miles. This of course was no use, as Whe country i is covered with ranches and bees at that distance would not do. any good at Penryn. I recommended Mr. Butler to try a couple of hives to begin with, and to get them placed among the trees at once. ‘This was done, and the benefit was felt the very same year. We were asked there in June; and Mr. Butler showed me his trees and said it was the first time he had had so much fruit and was quite satisfied that it was the bees. He was so pleased that he got some more hives, and the VOL. XXXV. : | P 202, JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. following year the trees bore so abundantly that the fruit had to be thinned. In this case, also, an unproductive ranch was converted into a productive one. This was not all, however, for the neighbours also began to feel the benefit and small fruits that were not very profitable began to yield sufficiently to become profitable. ‘There is another aspect in connection with the fertilization of fruit trees in which bees are indispensable. It is well known that some are self-sterile, and require pollen from another tree brought to them to make them fertile. A tree is self-sterile if it cannot set fruit unless planted near other varieties. An indication of self-sterility is the continued dropping of young fruits, and is generally overcome in California by planting other varieties among the self-sterile ones. Cross-pollination is thus obtained by means of bees or other insects, but, Fic. 72.—Puum ‘ Buack Di1Amonp.’ as at the time of fruit blossoming there are twenty bees flying to any one other insect, it is evident that cross-pollination is principally dependent on them. Even with fruits that can fertilize themselves it is an advantage to have cross-pollination, as the result is larger and finer fruit.” From my own experience I can fully endorse all that Mr. Cowan says about the utility of bees to the fruit grower. In the neighbourhood of London and other large towns one often hears the remark that plum and pear trees will not bear fruit because of the smoky atmosphere. It is not the atmosphere so much as the absence of fertilizing insects, especially hive bees, that is the cause of sterility. The trees blossom, and as I have proved by actual experiment, will bear fruit if bees are brought to them while they are in flower. It is important, in our uncertain climate, that the bees should be near the fruit trees. In 1907 the spring weather was very uncertain, and . BEES IN RELATION TO GARDENING. 203 many fruit growers in my neighbourhood had very poor crops. In the short intervals of fine weather, however, my bees were so busy on the blossom, that my trees bore heavy crops. Fig. 72 shows a branch of a ‘Black Diamond’ plum and fig. 73 a ‘ Pond’s Seedling’ plum, both photographs taken in 1907. There are few fruit growing districts that are really adequately supplied with bees, and capital amounting in the aggregate to many millions of pounds is either unremunerative or only partially remunerative. Instead of being an expense, bees are the most remunerative agricultural Fic. 73.—Puum ‘ Ponp’s SEEDLING.’ investment with which I am acquainted. Under proper management there are few districts in this country where the sale of the bee products alone will not repay the outlay on bees and hives in two or three years. A careful examination of a fruit district by an expert bee-keeper who has some horticultural experience would, in most cases, reveal whether the district is sufficiently supplied with hive bees. The British Bee-keepers’ Association, which is to apiculture what this Society is to horticulture, has affiliated Associations in the chief counties of England and is always pleased to assist in this or any other question connected with bee- keeping. Pp 2 204 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. THE GARDENS BY THE LAKE OF COMO. By James Hupson, V.M.H. (Read August 31, 1909.] THE gardens that I have had the privilege of visiting by the Lake of Como have, in my opinion, far more to recommend them than many others in Italy, some of which I have also seen: for instance, Isola Bella, on Lake Maggiore, shows, I think, far too much evidence of the skill of the architect and of the sculptor; and again, at the Villa d’Kste at Tivoli, there is a preponderance of waterfalls and of masonry. Too much artificial stone work mars the beauty of a garden, and detracts from its charm. Around Como masonry is not so obtrusive, at Tenet not in the gardens that I have seen. These gardens, like many others in Italy, owe their existence to the munificence of the Italian nobility of two centuries or more ago: those around Como probably to the Milanese families of high rank; those at Isola Bella to the Counts of Borromeo, and those at Rome to the Borghese family and others. | The gardens I have visited are situated chiefly at Bellagio, at Cadenabbia and at Menaggio. These beauty spots are comparatively close together, Bellagio being seen from both Cadenabbia and Menaggio, but Cadenabbia is shut off, so to speak, from Menaggio by the contour of the lake. To my mind, having seen Como from the town of Como itself, up to the northernmost point of the lake, there is no spot to surpass in beauty the three that I have named. True, I have not been down the Lecco branch of the lake, and therefore cannot make a com- parison with that, but I do not think it can possibly surpass these in beauty, or in the grandeur of its scenery. My two visits have been in August. On the first, the weather was intensely hot, with scarcely any breeze, but on the second the heat was tempered by a cooling breeze blowing down the lake from its northern extremity. Last year I stayed for some days at Lugano, another lovely spot, where it was decidedly warmer than on Como. From the lake we visited Monte Generoso, 5,590 feet in height, where we had a magnificent view of a wide range of mountains towards the north and north-west, © with the Lake at our feet; while to the east we could clearly discern the Lake of Como, with the town of Bellagio upon its promontory. I had often wondered how it was that such tropical luxuriance was to be seen around Como. Now, from this view point I could see how the lake is surrounded by mountain ranges from 2,000 to 3,000 feet in height, and the gardens upon its shores sheltered from the extreme cold, and nestling in such favourable situations along the water line. The shelter from keen biting winds, and the clear Italian sky explain a great deal, while the moisture arising from the Lake itself must be SERCTENE to luxuriant vegetation.

Before describing the gardens around Como, I wish to refer briefly to those at Lugano. One cannot but be struck with the remarkable growth some plants attain, and how they thrive in the most luxuriant fashion. This was particularly the case with Bignonia radicans, the sight of which in such profuse flower might carry one’s thoughts to the gardens around Algiers. The soil in which it grows so well is a stiff calcareous loam in which lime rubble and the débris from the mountain sides were freely incorporated. In England we usually grow it in rich soil with either peat, or leaf-soil predominating. This is, as we know, conducive to growth, but not so much to floriferousness. The best examples that I saw were at Lugano. Nerium Oleander also thrives well around the Lake wherever the sun shines for a good part of the day. This plant is cultivated in soil similar to that in which the Bignonia thrives, in almost every instance. It may often be seen projecting from the sides of the walls that hold up the garden fronts of the houses, where it appears to have been planted when the walls were built. It isa plant that evidently thrives well in the full blaze of the sun, where its growth becomes well matured and capable of withstanding several degrees of frost. The Oleander, to give it its more popular name, is equally at home in the gardens around the Lakes of Como and of Maggiore. The best examples of Nelwmbiwm speciosum were also at Lugano, _ where, in the gardens of one of the principal hotels, I saw a fine mass growing splendidly and showing abundance of buds. This also was in the full blaze of the sun, a pool having been made for it upon the sloping bank leading to the hotel. After traversing.a most delightful and fertile tract of country, we stayed for some days at Menaggio, which we made our centre. In the hotel garden there were several immense bushes of Oleander; these were in most profuse flower and formed quite a feature. There are several distinct forms of Oleander in Italy: the ordinary double pink-flowered variety ; the white, quite pure in colour, and semi-double ; and some very briliant singles, one of which struck me as being most distinct and effective wlth its brilliant deep crimson flowers. Other shades of singles were also to be seen. (I may note in passing that twenty years or more ago there was a collection of Oleanders at Chiswick in which there were many different shades of colour.) At the same hotel and in a portion of the garden running down to the Lake-side were several well-grown plants of Sophora japonica pendula flowering freely as standards. This plant is perfectly hardy, in the south of England at least, and should receive more attention and be planted more freely than at present ; it is a most graceful and effective subject for the water side. The first garden we visited at Menaggio, about 300 to 400 feet above the town itself, was the garden and extensive pleasure grounds of the Villa Vigoni, at one time known as the Villa Mylius. From these grounds a magnificent view of the Lake is obtained, showing the three arms into. which it is divided at Bellagio, as well as of that town itself. The Villa, a palatial building, is finely situated amid most luxuriant vegetation, being sheltered upon its northern and north-eastern sides. Immediately 206 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. surrounding the mansion is a lawn kept somewhat in the English style, and in the best of condition, with but few flower-beds to mar its beauty. Upon the walls of the Villa were Tecoma jasminoides flowering most profusely, Mandevilla suaveolens as we rarely see it in Hngland, Solanum jasminoides making a good display, Bougainvillaea glabra Sanderiana doing well, its bracts being of a deeper shade than usual (this was also grown in bush form and plunged in the grass here and there). A species of Sterculia—probably S. nobilis—was in profuse flower, as well as an Abelia that I did not recognize. In the open, Lagerstroemia indica was just opening its first highly coloured blossoms, the plant being in luxuriant growth. Hydrangea paniculata was grouped in masses, and of the purest possible white, better than we usually see it in England. Desmodium penduliflorum (syn. Lespedeza bicolor) was thriving well. Of Diospyrus Kaki there were several specimens which made me quite envious. Hzbiscus sinensis was doing well with many flowers to expand. The upright Cypress, such a fine feature in the Italian landscape, was planted in permanent situations with telling effect. Passing from the mansion, the lawn is broken up into shady glades and walks where the grass, somewhat mossy, is not kept so close as we see it in English gardens, a system that we might, I think, adopt more than we do with distinct advantage, both in ultimate effect and in the saving of labour. In a sheltered spot—ze. sheltered from the . prevailing winds—I noted a grand mass in vigorous growth of Musa yaponica. ‘The pleasure grounds away from the mansion are almost entirely of an undulating character, the natural outcome of their situation upon the lower slopes of the mountain.‘ This permits the attainment of many charming effects and of the choice of spots congenial to the growth of various shrubs and trees. Many palms were thus advantageously placed with distinctly good effect; among them fine specimens of Pritchardia pacifica and of Chamaerops Fortwunei (syn. Trachycarpus excelsus) : the former remarkable for its stout, sturdy stem, and the latter for its height. Of Bamboos there were huge masses of Phyllostachys mitis, which is evidently a favourite form in this locality ; several of these were more than 80 feet in height. There were also P. aurea and P. nigra which were, though not so tall, in fine condition. The Coniferae were represented by Araucaria imbricata, dark green in colour, dense in growth, and in more than one instance with cones developing. Cupressus funebris (the Weeping Cypress) first sent to England by Fortune from Northern China, was in good condition and | character, especially one very fine specimen such as we rarely see in this country. What struck me as most remarkable among the many fine Coniferae in this garden was an immense spreading growth of Juniperus Sabina, the original stem of which was only about 4 feet in height (knotted and gnarled in all directions), and at that height put on its drooping habit and covered a space about 50 feet by 40 feet with dense, dark green, healthy foliage. The ground upon which it rested sloped sharply downwards, and when looked at from below was one dense mass of verdure. Among Acacias there were several good plants of A. dealbata THE GARDENS BY THE LAKE OF COMO. 207 and A. cultriformis, the latter not nearly so much cultivated, I think, agit should be. A. lophantha had also grown into a fine specimen. The gardens around Como are noted for the remarkably fine specimens of Magnolia grandiflora. There is in this garden an example hard. to surpass, still growing most vigorously. It is not less than 60 feet in height, and well furnished. A large spreading Lawrws Camphora was also a prominent feature of interest. Indian Azaleas were grouped in ereat masses, and must, when in flower in the spring, produce a fine effect. Jasminum grandiflorum was, among many other climbers, most noteworthy. In shaded positions, chiefly on sloping banks, Cyclamen hederaefoluum was just commencing to flower. The outstanding feature of this fine garden was its good keeping with a minimum amount of lawn mowing, and dense carpeting, here and there, where grass would not grow, of what I believe to be Smlacina yaponica which is of a grasslike growth with white flowers and charming blue berries ; it is known in French gardens as L’ Herbe aux Turquoises. No symptoms of drought are to be seen in this beautiful garden, for water from higher altitudes percolates through the soil sufficiently to prevent this. ‘The shaded walks in the grounds make it possible to take as much - exercise aS one may desire, even in the hottest weather, and the pleasure is enhanced by the fragrance of the pines. The garden of the Villa Carlotta at Cadenabbia, which we next visited, is better known than that of the Villa Vigoni. As one journeyed thither by boat the many plants of Oleander to be seen even in the smaller villas en route formed a very striking feature. Frequently Lagerstroemia indica kept it company. Well-shaded pergolas, covered some with vines, others with Wistaria, and others with Fortune’s yellow Rose, were passed on the journey. Upon entering the garden, the Villa Carlotta is seen at the end of a lovely vista, situated a considerable distance higher up and ap- proached by terraces, every possible opportunity being taken of clothing the walls either from below, or from above, with a diversity of climbing plants. Other plants are employed upon the walls in vases or ornamental pots. It is in fact a most beautiful vista either to look up, or to look down when one has arrived at the topmost terrace. In a large circular basin many of the hybrid Nymphaeas were thriving well and flowering freely without that robust growth to which they attain in this country. N. lucida, N. Marliacea chromatella, and N. odorata suavissima were the most conspicuous, and all the twelve varieties were luxuriating in the warmth and sunshine. Near this pond were four fine plants of Caladium esculentum, well adapted to their positions, as were some fine plants of Papyrus antiquorum. Here and there were dotted plants of Impatiens Holtz flowering freely. Several plants of pink Ivy-leaf Pelargoniums of varied shades stood upon the terraces and drooped over the walls, so that they were seen to the best advantage from below. Another plant employed in a similar manner, but stood upon the parapets, was fiusselia juncea, and wreathed in its bright scarlet blossoms it produced a most beautiful effect. These were always placed in the warmest positions, and not necessarily near to the pink Geraniums. Of other flowering plants Bignonia radicans, a very tall plant, was a most lovely object, its blossoms being highly coloured. Well ripened wood 208 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. undoubtedly aids it in producing a profusion of blossoms. In the some- what shaded nooks of this terraced garden good use is made of the Myrtle, particularly of the Box-leaved variety. Here and there a fine specimen of Phormium Colensoi in a pot added to the effect, as did the fine-foliaged Bonaparteas, especially B. juncea. Upon a broader plateau running right and left in front of the Villa are the noted pergolas of Oranges, Lemons and Citrons, a sight well worth the journey to see. Where it is possible (not in this country, of course), no better subject can be chosen with which to cover a pergola. One scarcely knows which to admire the more, the beauty of the fruits or the fragance of the many flowers.. Among the many fine plants upon this plateau are some of Musa Ensete, with a little carpet-bedding surrounding them—somewhat, I think, out of place. After passing through the cool marble saloons, so well known to tourists, we come upon huge but graceful masses of Bamboos including Phyllostachys mitis, P. aurea, and P. nigra, a trio that it is hard to beat. These are very tall, especially P. metzs, and in luxuriant growth, and are well placed in the immediate neighbourhood of the Villa itself. Bambusa yaponica (syn. B. Metake) was not far removed from these, and fully 20 feet in height, forming quite an archway over the path. These gardens also are noted for their fine specimens of Magnolia grandiflora, the largest of which is quite a tree, nearly 60 feet in height, with a stem measuring 5 feet in circumference at a few feet from the ground. Near this Magnolia is a grand old plant of Wistaria sinensis, also with a fine trunk of its own near the ground, while higher up its branches seek support from other trees. In a sheltered and moist spot grows a fine example of Philodendron sp., the ground being carpeted with the blue Lycopodium—J. caestwm—ain its true colour. Soon after we came upon quite a forest of Phyllostachys mitis, the finest mass I have ever seen, about 40 feet in height, with stout, robust stems. Here, too, there are, as may be expected, several fine specimens of palms. A sturdy old veteran is Phoenix dactylifera, with a stout stem of fine proportions. Brahea filamentosa (syn. Pritchardia filtfera) is also a prominent object in a sunny position and ina similar situation there is a fine specimen of Cocos australis, a slow-growing, but extremely handsome palm when seen, as here, with its typical glaucous-grey foliage. In another spot Phoenix canariensis, which grows so well along the Riviera, is equally at home here. Of the Chamaerops there were dense masses of C. humilis in their true character with glaucous-green leaves, and of C. Hortunei, which with their tall stems, had a distinctly good effect. Several of these palms were to be met with in well chosen situations, and generally upon sloping ground, their needs as regards - moisture being undoubtedly supplied from the water percolating through the soil from the higher levels. The same remark applies to the many fine examples of the Conifere to be seen here, as at the Villa Vigoni. At the Villa Carlotta, however, there is a preponderance of trees that are of a rather more tender character; the difference in altitude will explain this. Among the many large trees the most notable are Abies orientalis, 50 feet or more in height, quite hardy in cooler localities, but here in fine condition ; Picea Morinda (syn. Abies Morinda), also evidently quite at home; Cupressus Photo: Brunner, Zurich. Fic. 76.—Patms AND DRACAENAS AT VILLA CARLOTTA.

In one instance a tall climbing China Rose had entwined itself among the branches with a picturesque effect. Of the genus Retinospora several good specimens are to be met with. The Lebanon and the Hima- layan Cedars—Cedrus Libani and C. Deodara—were thriving as large specimens, both evidently enjoying the clear atmosphere and the moist heat. Araucaria braziliensis, tender in this country, was quite at home there. One very fine feature is the dell, apparently a natural formation, wherein are to be seen Hydrangea hortensis of a deep blue colour, amid the shade of Bamboos and of Plane trees above them. One comes upon all kinds of surprises in these gardens—here a lovely peep of the Lake, with the mountains in the distance, and there in a sunny warm spot a group of characteristic plants. For instance, upon almost inaccessible ground there will be groups of Agaves, Aloes, Yuccas and the like, and again groups of Phormiums where the soil is moist. If the ground slopes more than usual, a congenial home is found for many of the Cactus family, and Lotus pelyorhyncus thrives well in similar situations. In quite moist and shaded spots Strobilanthes Dyerianus was growing well and in good character, and not far from it I saw Maranta zebrina. The better varieties of the stove Dracaenas were also succeeding well, being bright in colour. For these and similar plants a carpeting was made of Fittonia argyronewra. The large masses of Azalea indica alba were particularly fine, and in their season must give a wealth of blossom ; they were chiefly in groves or on grass. A fine old tree of Ginkgo biloba (syn. Salisburia adiantifolia), with a Virginian Creeper, approaching its autumnal tints, clinging to its stem and lower branches, formed a pretty feature. In deep damp recesses there were large masses in rampant growth of Adiantum capillus-veneris. As at the Villa Vigoni, a free use of Snulacina japonica was made for carpeting the ground where it was hopeless to think of grass growing at all. This fine garden is full of interest to every plant-lover, and is kept in admirable condition. A portion of the front, next the Lake and near the Villa, has a fine avenue of Plane trees, which forms a cool resort during the heat of the day. This avenue is alluded to by Longfellow in his ‘Poem of Places.’ ‘I pace the leafy colonnade Where level branches of the plane Above me weave a leaf of shade Impervious to the summer rain.’ From Cadenabbia it is easy to reach Bellagio by the steamers that ply upon the Lake. The garden front of the Grand-Hotel Bretagne at Cadenabbia is very well kept, and the Oleanders were just coming into full flower, and Lagerstroemia indica, which had thriven so well in the past as to have had a severe pruning, was now showing for flower again. ‘Tall palms, chiefly Chamaerops Fortunei, formed imposing features. Wvstaria sinensis was flowering quite freely owing to the exposed situation and the warmth. Dianthus ‘Napoleon IIL’ planted in masses in beds was flowering well, and so were Celosias and Cockscombs. The finest effect, however, was got from the large masses of Hydrangea 210 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. hortensis, of the deepest blue, planted upon banks facing west; these were really splendid. Bignonia radicans, growing in the bush form, was most effective. Musa japonica, as a foliage plant, added to the pleasing features of the garden. Our next visit was to the garden of the Villa Melzi, which, speaking generally, faces north-west, so that in the shade cast by the luxuriant forest trees there are many cool spots where several plants thrive well, and in sunny places full advantage is taken with plants that require more warmth. The gardens skirt the Lake for a considerable distance, but do not appear to extend so far back upon the higher ground as some others that we visited. Here there is a considerable expanse of turf interrupted by fine trees and Bamboos, but not so much as to obscure the scenery. It has in fact in many respects much the appearance of a well-planted English garden. Here, again, are some fine masses of Phyllostachys mitts, producing a good effect, with stems bare at the base for several feet ; these reach fully 40 ft. in height. Planted in a similar way was Musa japonica, which when arranged in groups is, I think, much better than where only a few growths are allowed. Groups of Chamaerops Fortunei, containing plants sufficiently far apart to afford perfect development, formed at a distance most striking objects. ‘There is, too, a fine evergreen Oak which the gardener told me was Quercus mexicana. Conifers, too, are planted in groups, and some were already suffering from being planted too closely. One excellent example of this system of planting, not so much crowded as some others, was afforded by Cedrus Deodara. Of Cedrus atlantica glauca I noticed one very fine specimen, the finest I have ever seen. T'suwga canadensis (the Hemlock Spruce) is represented by a fine specimen 50 feet or more in height, and well developed. Picea Morinda (syn. Abies Smithiana and A. Morinda) was in its true character, with long pendulous branches. Pinus palustris was represented by a fine example—the tree, it is true, was an old one, but none the less handsome. There were several good specimens of Thuwjopsis dolobrata variegata, with the silvery variegation well marked. In the warmest spots I noted Hibiscus rosa-sinensis employed as a bedding plant, but I remember to have seen it better in these gardens in 1899. Canna ‘King Humbert,’ to use its English name, is also bedded out here as it is in England, but grows much finer than we can hope to have it. It is one of the very best Cannas for bedding. I have used it in this way for several years now. (Its long deferred recognition was only made at the last Meeting of this Society, on August 17, when it gained an Award of Merit.) It is handsome ‘both in foliage, with its dark bronzy red colouring and leaves fully 1 foot in width, and in its flowers, a rich - orange crimson, while it has so sturdy a growth as to withstand the wind remarkably well. Rwsselia juncea was again seen here as a vase plant and nothing could be more effective than the dozen vases of it all in perfect condition. There is also a large and thriving collection of Citrons, Oranges and Lemons in large vases. Towards the end of the gardens, and nearer to the town of Bellagio, is a sheet of water with several of Marliac’s water lilies upon it, but the situation is rather too shaded for them to flower freely. Near here, but in an ideal position, were again seen numbers of Hydrangeas still of the deepest blue; more were being planted. At this end of the garden one might imagine THE GARDENS BY THE LAKE OF COMO. 211 oneself in one of our Devonshire gardens, the Firs and other forest trees being of large size with broad grassy walks among them. Our next visit was to the Villa Giulia which occupies a unique position: the front of the Villa faces in the direction of Cadenabbia, whereas the gardens run down to the water upon the Lecco branch of the Lake. Towards Cadenabbia there is a broad avenue of the upright Cypress which forms an imposing feature, now that the trees are well developed, from whichever end it is viewed. At the entrance there is a large group of Chamaerops Fortune: consisting of many tall specimens of different heights. Here again the blue Hydrangea was seen just at the season when at its best. Several specimens of the Date Palm also grow towards the pleasure grounds on the farther side of the Villa. An avenue of Horse Chestnuts, casting a heavy shade and affording a cool retreat, is planted in the pleasure grounds. Avaucaria braziliensis thrives, and in favoured situations palms, including Phoenix canariensis, were growing into large trees. A distinct-looking Hwuonymus called EH. fimbriata, which is not hardy, I think, with us, grows in this garden. Magnolia grandiflora, where seen as it is here, and in other favoured localities, of tall growth and pyramidal outline, with its lustrous green foliage, is a distinctly fine feature of the garden. A grand view is obtained from the garden front facing down the Lake (the Lecco branch) across to the mountains beyond. The best specimen hitherto seen on this tour of Latania borbonica (syn. Livistona australis) occurs here; it was growing well, but cannot, even at its best, be a serious rival of either Chamaerops Fortunei or of Pritchardia pacifica. A great feature of this garden is presented by the terraces by which the Lake is at last reached. They do not form an obtrusive feature, and each plateau and the walks also are clothed with verdure. No set design is aimed at, but every plant is placed with due thought and regard to its requirements. The upright Cypress was planted in appropriate spots and grown into specimens exceedingly good and vigorous. Upon one of them a Wistaria had established itself for support, reaching 30 feet or more up the stem. Tall Oleanders were jutting out of the walls and, as usual, flowering freely. A fine avenue of Citrus was formed of Specimens in large vases. In a shaded spot a group of Justicia rosea, in full flower, formed an uncommon feature in the open garden. For the first time I noticed Brugmansia suaveolens, and it was flowering well. (It is to be regretted that this Brugmansia is not more grown in English gardens than it is. Where not infested by the insect that punctures its leaves in quite an early stage of development it forms a fine plant. What the insect is, I do not know.) Where water drips from terrace to terrace, fine masses of Papyrus antiquoruwm and Arundo Donax variegata were planted. Groups of Azaleas were also planted on these terraced gardens. The Wistaria is found most useful for covering the balustrades, and Magnolia conspicua finds a congenial home on the walls along with Bignonia capreolata, which is no doubt the best species to grow outside in England. Sophora japonica pendula was so planted and grown as to form a grateful shade for a seat; Lawrus Camphora had monopolized a considerable Space, and formed a fine feature, not so fine, however, or so large as the large specimen in the gardens at Isola Bella, on Lake Maggiore. 212 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. Cryptomeria japonica thrives well, and is very much happier than I have seen it in England. In quite a sunny spot Punica granata fl. pl. —the Pomegranate—fiowers freely along with Paulownia imperialis, which, when flowering, forms a conspicuous object with its many-flowered panicles of large blossoms. Both the Loquat (Photinia japonica) and Diospyrus Kaki were in good condition upon the terraces and in warm recesses. The steps leading to the Lake and boathouse descend, at last somewhat steeply, so I did not follow them, but one could not fail to observe their attractive features. From this spot we ascend again by shady walks and pass on the way several fine examples of Cedrus Deodara, Sequoia gigantea—a very fine, healthy tree—and other Conifers, as well as a group of Musa japonica, which is now evidently more in favour in this locality than Musa Ensete. Every opportunity is taken to make the most of the space, and every turn has something to interest the lover of a garden. Villa Serbilloni next claimed our interest. It is situated upon the promontory forming the extreme northern boundary between the Lecco and the Como branches of the Lake, and the view embraces a wide expanse of country, including, in many instances, the Swiss mountains, with their snow-capped summits. This Villa is now a dependence of the Grand-Hotel, Bellagio. It has many natural advantages, which might be made much of if it were in the hands of a garden enthusiast ; now the tendency is, to a great extent, to cultivate it from the utilitarian point of view. Here are breaks of Indian Corn thriving well, and there vineyards in suitable aspects, with in addition many Olive trees, until one reaches the higher ground; for this Villa stands well above the town and its surroundings. From the time of entering the gates the carriage road is throughout of a winding character until the summit is reached far above the Villa itself. From the several admirably arranged view-points beautiful prospects are opened in almost all directions, including a wide expanse of the Lake. From one particularly good spot we could see across to Varenna, while at this point it would be possible to cast a stone down the precipice into the Lake, some hundreds of feet below. Most of the pleasure grounds and parterres are near the Villa, where there is also a small nursery and a reserve garden. On dry sunny spots a free use is made of the larger species of Agaves and of the hardier Yuceas, the latter flowering freely. There are also several fine specimens of palms, some of which appeared to have been recently moved. These were placed in admirable positions for effect. Magnolia grandiflora, as usual, was thriving well. Among Conifers a fine specimen of Sequoia gigantea clothed to the ground with branches was noteworthy. One of the chief features of the uppermost part of the grounds is the forest- - like appearance of the surroundings, so that one might imagine he was back in England again. There are several other well-kept and noted Villas around this portion of the Lake, but we had not the time to visit them. Among them Villa Trivulzio, formerly Villa, Poldi, Villa Trotti and Villa Pliniana. These are all worth visiting. Each of the gardens visited had distinct features oi its Own, and no two possessed quite the same natural advantages. The Italian gardener is painstaking in his work, while the courtesy shown to us, and the information given, whenever asked for, were quite characteristic of the Italians and in every respect most admirable.

(a and B slightly reduced, c and p greatly magnified.) widely separated localities, mainly in the south of England, though the disease is not confined to any particular part of the country. The first symptom of the disease is the appearance of small yellowish- brown spots on the upper surface of the leaves (fig. 81, 4) and on the 214 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. leaf stalks and stems (fig. 81, B), perhaps more particularly at the nodes, though not by any means confined to that part. Frequently the spots first appear a little above the base of the stem, but they are to be found in any part right up to the flower. The spots on the stem are usually much paler than those on the leaves, when they first appear. The tissues around the spot are filled with the mycelium of a fungus and the cells attacked are killed. The spots rapidly enlarge, and on the leaves often run into one another. As the fungus spreads the tissues right through the leaf are killed, so that the spots are evident on the lower surface as weil as the upper. On the stems the spots increase in size lengthwise more rapidly than in diameter, so that they soon assume an elongated oval form, sometimes reaching a length of two inches or more. As time goes on the tissues are killed completely round the stem, and subsequently the whole of the stem, above the spot attacked, wilts, turns brown, and dies. The spots become darker in colour and finally almost black, owing to the presence of numerous very dark brown stiff bristles (fig. 81, p) standing up from the diseased spots, among which the colourless spores (fig. 81, c) are produced in great numbers. Several correspondents have stated that the disease has spread through and killed all the plants of this species in a garden, and it is certain that when it once appears its progress is rapid and the havoc it causes certain ; furthermore it has not proved at all easy to combat. The disease is caused by the fungus Colletotrichum malvarwm, a species which was first noticed in 1854, and described by A. Braun and Caspary * under the name of Stetrochaete malvarwm. In 1890 South- worth,r writing of a new hollyhock disease, described the same fungus under the name of Colletotrichum althaeae, thus putting it in its proper genus, but overlooking the fact that it had been described previously under another specific name than althaeae, and under this name Massee + and Cooke § refer to it. Until 1906 it was unknown in this country, but in that year it was recorded as having been “collected by Mr. Wishart at Alyth, Perthshire, on a malvaceous plant,’’|| and, as we have pointed out, it has since that time appeared in many parts of this country. Kriksson found it in a garden in Stockholm on a species of mallow in 1883, and in America it has proved very destructive to hollyhocks. We have not yet seen it upon hollyhocks in England, but, as it has attacked them so disastrously in America, it is to be looked for upon them here. The symptoms of the attack on the hollyhock are similar to those described above. Repeated sprayings with Bordeaux mixture, while they have checked the disease to some extent, yet have not sufficed to stop its progress completely. This fungicide is, however, the best that is available. Plants which show the symptoms of the disease should be destroyed by fire as soon as possible after its appearance.

Although it has not so far been directly proved that the disease is conveyed in the seed, it would be best not to save seed from affected plants, particularly as the commercial “seed ’’ is not only the seed proper, but is surrounded by a part of the old plant on which the fungus may often be found growing. Several of the plants recently examined showed pustules of the fungus, not only upon the flower, stalks, and calyx, but also upon parts of the ovary itself. If the mycelium should prove itself capable of withstanding the drying the “seed’’ undergoes, the source of infection is thus conveyed in the “seed.” Hven if this were not the case, it would be quite impossible, unless the “seeds’’ were treated with some disinfectant, to guarantee them free from adherent spores of the fungus which might well survive the winter and propagate the disease in the following season. 216 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. VIL—A DISEASE oF ANTIRRHINUM. By F. J. CuittEnpven, F.L.S. In the summer of this year specimens of diseased Antirrhinums were received at the Laboratory from Devonshire. Nearly every plant in the garden from which they came was diseased, though they were planted in different aspects and in various kinds of soil. The leaves of the diseased plants had numerous yellowish sommded spots upon them (fig. 82, a), and in some cases these spots were so numerous /) hy j [ oe 405 Fic. 82.—SEpToRIA ANTIRRHINI.

In addition somewhat similar, elongated-oval- dead spots were present on the main stem and its branches (fig. 82,8). In some instances the dead areas upon the stem passed quite round it, forming a girdle of diseased tissue, and then all above the diseased spot, being cut off from the water supply from below, died and dried up. The diseased plants therefore presented a very forlorn appearance, failed to flower, and in most cases soon succumbed to the attack. The disease proved to be due to the attack of a fungus which has not previously been known to occur in Great Britain, though it is known in parts of Western Europe, having been recorded from France, Italy, CONTRIBUTIONS FROM THE WISLEY LABORATORY. 217 and Portugal. It is evident that under certain conditions, if the fungus once gains a foothold, it is capable of causing very serious damage to these popular plants. The genus Septoria, to which the fungus belongs, is a very large one and contains many species which do considerable harm in a very short time. Though the area killed by a single individual of the fungus is usually small, yet the spores are produced so rapidly after infection first takes place, and in such abundance, that the spread of the fungus is rapid, and the destruction of the whole plant in the case of such a plant as the Antirrhinum is a question of only a few days. The fungus which is the cause of the disease is not known to attack any other species of plant, and has received the name of Septoria Antirrhim Desm. Careful examination with a lens will reveal, scattered over the yellowish spots on the leaves and stems, exceedingly small darker spots. These are the fruit bodies of the fungus, and the spores, which are long and narrow (fig. 82, c) and thickly packed within the fruits, escape when ripe by a small pore at the apex. They can germinate at once provided moisture and a suitable temperature are available. Since Antirrhinum majus has become naturalized in this country, particularly in the south, if the disease should spread it will probably prove very difficult to eradicate. Wild plants would serve as breeding grounds for the fungus whence it would continually spread to the cultivated ones. It would, therefore, be well to burn any plants that are attacked badly so as to destroy the spores completely and quickly. Asa means of protecting plants which have escaped, and the whole of the plants in a succeeding year, spraying with Bordeaux mixture or a solution of one ounce of potassium sulphide in three gallons of water should be resorted to. Where only small groups of plants are concerned hand sprayers may be used. Small, light and handy little spraying outfits, producing a very fine mist-like spray of just the kind suitable for such a purpose, may now be obtained. Where larger numbers are required to be sprayed a knapsack sprayer answers the purpose best. As the fungus has not previously been found in this country a description is appended : Septoria Antirrhini Desm.—Spots yellowish ; perithecia on both sides of the leaf, very small, 50u—70p in diameter, rather prominent, numerous, crowded or scattered, with an opening at apex; spores cylindrical, obtuse, bent or curved, 4—7-guttate, one-celled, 15-20 x 2-2°5u.

A curious fact concerning the Banksian Rose has this year come to light. The double white form of Rosa Banksiae was introduced to Kew in the early part of the nineteenth century, in 1815, but Wm. Kerr, according to a note in the Botancal Register, had it in cultivation as early as 1807. The double yellow was introduced some years later, and the single yellow only made its appearance about 1870. ‘The typical form, the single white, remained unknown, though many inquiries were made for it in France, where these climbing roses abound in every garden in the Riviera, as well as in Italy and Switzerland. Four years ago I found a rose erowing on the wall of Megginch Castle, Strathtay, Scotland, which seemed to me a very slender-growing form of R. Banksiae. Captain Drummond of Megginch told me it was a rose that his ancestor, Robert Drummond, had brought with other plants from China the year his brother, Admiral Sir W. Drummond, had cruised in the China seas, in 1796. This old rose had been repeatedly cut to the ground by severe winters, and rarely if ever had been known to flower. The impression, however, was that it was white and very small. Captain Drummond kindly gave me cuttings, which I took to Nice, and this year they flowered, proving themselves to be the typical single white Banksian rose so long sought for and hidden away in this nook of Scotland for more than a hundred years. The introduction of the Banksian rose, therefore, is due to Robert Drummond of Megginch, who brought it from China in the year 1796. THE SWIFT MOTH CATERPILLAR AND DAFFODILS. 919 THE SWIFT MOTH CATERPILLAR AND DAFFODILS. By H. R. Daruineton, F.R.H.S. So secret and so close As is the bud, bit with an envious worm, Ere he can spread his sweet leaves to the air Or dedicate his beauty to the sun. Could we but learn from whence his sorrows grow We would as willingly give cure as know. Romeo and Juliet. My object in calling attention to the attacks of the swift moth caterpillar (Hepialus lupulinus) on daffodils is twofold. I have found it extremely destructive in my own garden, and hope that a discussion of the matter may bring some useful suggestion of a means of effectively dealing with the difficulty ; and I have reason to think that some who have sutfered in the same way may welcome a discussion of the subject and take some interest in my observations, while it may assist others whose daffodils have failed from the same cause, though they have been unable to deter- mine the reason of the failure. I have no doubt that the destruction caused by this caterpillar is much more widespread than is generally known.* On two occasions, in different parts of the country where I have been assured, ‘Oh, we cannot grow daffodils here,’ I have found the grub in the immediate neighbourhood of the ground considered to be hopeless for the purpose. This may of course be a coincidence, but it is possible that if the cause of failure be as I suspect, by taking proper precautions the daffodil might be grown in those places where it has hitherto been found to fail. The swift moth is unfortunately an extremely common moth. At the same time the books on British moths tell us very little about its habits and, so far as | am aware, nothing as to its partiality for the daffodil. The life-history of the swift moth is somewhat as follows :—The moths appear towards the end of May and continue through June. The female is decidedly larger than the male. The colour in both cases is a dusky brown, but the wings are rather prettily marked with a pattern of a lighter colour. The male has a tuft of rufous-tinted down at the back of the thorax. The moths may often be seen flitting about the garden in the early dusk, with a peculiar zigzag flight, to which no doubt they owe theirname. These are probably males, the females lying below at the roots of the grass. The females begin to lay their eggs early in June. I have often tried to observe the moth in flight, but down to the present I am unable to determine whether the female moth lays her eggs deliberately on particular plants or in particular places, or whether at haphazard as * When I first called attention to the pest (Garden, April 27, 1907), Mr. Blake of Guildford wrote to that journal (May 18) stating that out of 160,000 bulbs grown by him something like one third had been affected by it. Q 2 220 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. she flies. Whichever method is adopted it is usual to find several cater- pillars hatched out close together. They may perhaps be hatched on the surface of the ground and then crawl down the holes left by the decaying foliage of the daffodil. I have, at all events, found the caterpillars in July in the scales of bulbs which had been dug from the ground in the middle of June. They were then, of course, very small, but had begun to feed on the bulb which was in process of being dried off. From July till the following May the caterpillars remain under ground feeding on various roots. I have read that they live on the roots of the dock.* I only wish they would confine themselves to so innocent and even laudable an amusement. Unfortunately any fleshy root seems to serve their purpose. Beside the daffodil and the dock, I have found them attacking the roots of the paeony, the tulip, the colchicum, the lily, the pentstemon, Chelone barbata, and on one occasion apparently the young roots of the hawthorn. Of the paeony they seem to be specially fond. They appear to be liable to be attacked in return by a curious fungus which will kill them, and they may then be found dead, slightly orange in colour, hard, and rather brittle. When they feed on the daffodil they seem, as a rule, to prefer to eat the roots and the bulb rather than the shoots. Sometimes the caterpillars will eat the roots right away, and also bore into the bulb, in which case the plant will either die altogether or push up a few miserable leaves ; and is practically ruined. In other cases the roots may be scarcely touched and the bulb only attacked; the plant will then throw a feeble crowth of leaves, seldom a flower. If a fork be inserted under the bulb noticed to be in this condition, and the whole thing dug up, the caterpillar may sometimes be dug up with the bulb, its head buried deep in the base of the bulb. This is, however, not always the case, and perhaps on account of the depth at which they generally work, it is not easy to find the marauder, even when one feels fairly confident that an attack is in progress, and though the bulb when lifted may give positive evidence of having been subject to attack. But the caterpillars will also sometimes eat the shoots as well as the roots and bulbs, and in such cases of course no leaves will appear above ground, and when the bulbs are lifted they will be found to present the appearance of concentric circles of bulb scales, both the top and base of the bulb having been eaten right away. It is, however, very unusual to find this, and I have noticed it only on two occasions. In both cases about ten or a dozen bulbs enclosed in a small partition on the rockery were attacked, and I suppose the caterpillars were numerous and unable to make their way to fresh bulbs after they had consumed the parts of the plants they liked best. In one case the daffodils so completely destroyed. consisted of a group of ‘Vesuvius,’ and in the other of ‘Queen of Spain.’ In all cases that have come under my notice bulbs attacked by the swift moth caterpillar, when subsequently lifted and examined, present quite a different appearance from bulbs which have been attacked by the * Morris states generally that they feed on the roots of plants. ————== = THE SWIFT MOTH CATERPILLAR AND DAFFODILS. 221 erub of the narcissus fly. The narcissus fly lays its egg in the foliage, and the grub which hatches out makes its way into the centre of the bulb, which it completely destroys, and ultimately it eats its way out, though it is occasionally found in the middle of the bulb when it has been lifted and dried off. There is nearly always found a hole from the base into the centre of the bulb, and sometimes another hole out on to the shoulder of the bulb. In a bulb attacked by the caterpillar one or more holes are seen to have been bored into the bulb, generally into the base; but the holes are not deep, and it is usually easy to see that they do not extend into the centre of the bulb. More rarely it may be found that a considerable part of the base of the bulb has been eaten away in an irregular patch. In either case the havoc wrought on the plant is sufficient to impair its vitality seriously and often to destroy it as effectually as though it had been visited by the narcissus fly. Apparently the caterpillar, having eaten a certain distance into the bulb, leaves that spot and begins again at a fresh place or on another bulb. This method of attack was particulary noticeable in the case of some colchicums, the smooth bulbs being pitted all over with little holes about a quarter of an inch deep. But the colchicum bulbs were not very seriously injured by the treatment, the bulb being, as it were, merely a storehouse for reserve material, and the growing shoot produced from the side of the bulb was not generally affected. The caterpillar when full grown is about one inch in length. The body is white and the head brown in colour. In the spring it makes its way to the surface of the ground and spins itself a cocoon. This proceeding begins in April and continues through May into the early part of June. The earliest date on which I have found a caterpillar spinning its cocoon is April 15, and the latest during the first week of June ; but by the middle of May most of the caterpillars have turned into chrysalides, and may be found a few inches below the surface. The chrysalis is of a yellowish chestnut colour, usually about seven eighths of an inch long and three-sixteenths of an inch in diameter, and when disturbed it wriggles a good deal, a habit which often leads to its detection. It is, however, not always easy to find the chrysalides in the soil, even when the condition of the plants raises a suspicion of their presence, and a careful search is made, and although the subsequent finding of the empty shells shows they have in fact been there, and have escaped discovery. The chrysalis stage continues for about three weeks, and the insect then wriggles to the surface and the moth escapes. I have some reason to think that this stage may be slightly shorter in bright warm weather than when it is cold and damp, but the difference is not very great. The hatching out of the moths commences towards the end of May and continues through June. The female moth is nearly an inch and a half across the expanded wings, and just under an inch in length of body, the abdomen being of approximately uniform thickness. The male is one inch and an eighth across the wings, and five-eighths of an inch -In length of body, the abdomen tapering towards the tail, and being Daphge JOURNAL OF THE ROYAL HORTICULTURAL SOGIS tya only about half the thickness of the larger moth and slightly darker in colour. : The moths are seldom to be seen flying during the day. So far as my experience goes, the only occasion on which they appear during daylight is when a bed is being disturbed in getting up daffodils for harvesting, and the moths have been reposing on the earth, and endeavour to escape. They come out, however, towards dusk, and may then be seen flying over the garden with their peculiar zigzag motions. Their active operations seem confined to a couple of hours before and after sunset. The long period over which the swift moths hatch out makes it rather difficult to devise methods for resisting the attack or for destroying the enemy. I will, however, mention the methods I have myself tried in the hope that others may be able to suggest more effective means of preventing or escaping from the evil. From the time when the caterpillar begins to approach the surface for the purpose of spinning its cocoon until the time when the moth hatches out from the chrysalis, that is to say, from the middle of April till the beginning of June, the insect is close beneath the surface, and may be sought for in the ground and destroyed. For this means to be at all effective the whole of the beds must be very carefully gone over and the soil moved and scrutinized to the depth of six inches and the operation repeated at intervals of ten days or a fortnight—a method obviously im- practicable in the ordinary border. It is also possible, though difficult, to catch the moths themselves when flying in the dusk, but these are generally males. I fear neither method will do more than mitigate the evil. I am told the moth is not one of those that can be caught by sugaring the stems of trees, or which is attracted by a bright light. I have not found the method of searching the ground for the females very successful. I have so found them only by accident. It is an unfortunate coincidence that the time of the caterpillar’s greatest destructive activity is precisely that of the principal root-growth of the daftodil—namely, from August till April—and during this period the creature is at work so deep in the soil, that it cannot be sought for without serious injury to the roots and bulbs we are trying to protect. I have tried the plan of surrounding the bulbs with sharp, gritty substances, such as” fine charcoal and ground oyster-shell ; but this proved quite a failure, and did not in any way prevent an attack. Then came vaporite apterite, killogrub, and similar remedies. It is possible I may yet find an effectual way of using these substances, and I am not prepared to say that they are wholly without effect—my gardener thinks they do produce some result—but no method I haye yet tried of applying them can be said to provide a complete remedy for the evil in the case of daffodils left in the ground and not lifted. In one small bed which had vaporite dibbled in between the bulbs in the autumn and again in the spring about one-half the plants were attacked, and I was able to discover some ten or a dozen of the caterpillars or chrysalides in the following May. If these substances produce their effect by means of a gas which they give off, and which acts chiefly in an upward direction, it is easy to under- THE SWIFT MOTH CATERPILLAR AND DAFFODILS. 223 stand the difficulty in getting the dressing, which has to be inserted by means of the dibble, placed sufficiently deep to destroy the grubs when feeding below the bulbs, and this may account for the failure of the autumn dressing; but it was nevertheless disappointing to find that the spring application seemed to produce little or no result on the grubs when they began to come to the surface for the purpose of entering the chrysalis state. I have no doubt that vaporite will kill the caterpillars in certain conditions ; for instance, if a few caterpillars be collected and placed in soil in an ordinary garden flower-pot a little vaporite added to the soil very soon kills them, but it is a different matter in the open, and I must admit my impression that this treatment has not proved an effectual remedy down to the present. Mr. Ellis has suggested to me that scattering vaporite or some smell- ing substance over the daffodil beds in June may possibly scare away the females from the beds, as he thinks they generally descend to the ground to lay their eggs. I have not yet tried this method. A device I have tried with a certain amount of success is to cover the the beds in which the daffodils are growing in the middle of May with a rough framework, and over this to stretch a wasp-proof fabric. Where this can be done it seems to afford sufficient protection, provided two precautions be observed. The first is to take care that the fabric is fastened close to the ground. Where this has not been carefully attended to I have found bulbs near the edge of the bed to suffer, though even then the attack has never proved a serious one. The second is to examine the bed very diligently in order to make sure that none of the enemy is present in the bed at the time the cover is placed in position. In this connexion it is to be observed that the presence of one or two only of the erubs may cause but small damage; no bulb may have failed to come up, and perhaps only one or two may have been without a flower, or shown some other sign of weakness. In such case any symptom of weakness must be regarded as a grave cause of suspicion. The soil must be most carefully moved and examined within a circle of about 18 inches round each plant showing signs of weakness to a depth of 6 inches at least, and the operation repeated a week later, after the covering has been put on. The covering has to be left on until the end of July. I need hardly say that this method, though fairly successful, if carried out as I have described is very inconvenient, and can only be resorted to in a place devoted solely to daffodils, and is quite impracticable in the ordinary border. It has, moreover, the additional disadvantage that it has the effect of keeping the ripening influence of the sun away from the plants just at the time when it is most beneficial to them. I think the use of this method of covering from the middle of May till the end of July is likely to be confined in practice to a few cases of rare or valuable bulbs which for some reason it is desired to retain in the ground for two or more years without lifting. } Somewhat reluctantly I am coming to the conclusion that in all probability the most effective way of outmancuvring this troublesome pest is by resorting to an annual lifting of the bulbs accompanied by a very careful inspection before replanting. Where this has been carried out and the precautions next mentioned observed I have never, down to 224 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. the present, found serious trouble to result. But in addition to the examination of the bulbs I think two other precautions should be taken. One is that the ground should be thoroughly well worked before planting takes place, and the other is that ground which has been subjected to a bad attack should not be again used for daffodils for at least a year after the affected bulbs have been removed. The only case I can recall in which freshly planted bulbs have been seriously injured occurred when I planted a batch of ‘Maurice Vilmorin’ in a spot in a mixed border from which the remnants of a group of ‘Flora Wilson’ had been taken up a month or two before. The latter had been almost destroyed during the previous year. The position selected was in the middle of a mixed border: it had not been found practicable to effectively work the ground after the affected bulbs were taken away, and no doubt the caterpillars when hatched out found subsistence on the roots of other plants until they discovered the newly planted daffodils. If I am right in thinking that annual lifting of the bulbs and working the ground carefully before replanting affords a means of avoiding the troubles caused by the pest, this may perhaps explain why so little has been heard of the caterpillar before this. Nurserymen are from the necessity of their business in the habit of practising both these pre- cautions, as well as of carefully cleaning their bulbs before sending them out, and so the large growers may have escaped being affected by the moth. : I have arrived at this conclusion with reluctance, because, in the first place, the annual lifting of all the daffodils, even where only a moderate number of plants are grown, is rather a serious undertaking and an uncomfortable disturbance of the borders; and besides this I think that many daffodils seem to produce their best blooms only if they are allowed to remain in the ground for two or three years without any disturbance. However this be, so far as my experience goes down to the present the annual lifting and replanting seems the most effective way of combating the evil I have described. I am indebted to Mr. Henry Ellis for identifying the moth and for making many suggestions. AMARYLLIS PARKERI. 92.5 AMARYLLIS PARKERI. 3 (A. Belladonna var. blanda x Brunsvigia Josephinae] By A.

THis bi-generic hybrid should be of great interest to those who study genetics, because the parents are so very dissimilar that we are presented with no less than 17 divergent characters to work on, and the fact that the hybrid is self-fertile will enable the subsquent generations to be analysed.

Parkert may possibly be the progeny of the original cross made by Herbert, and also that Messrs. Van Tubergen’s cross may differ therefrom because it is the reverse cross to that made by Herbert. This may be true of the A. Parkeri raised by Mr. Parker, for this was raised on A. Belladonna, but Herbert’s hybrid was raised * the same way as Messrs.

In examining the hybrid characters in which the blood of the male parent is evident, it so happens that in most of them the only evidence is in increased size and in number of flowers: just those characters that are influenced in so many cases by generous treatment and the appearance of which do not necessarily presuppose hybridization. Again colour is often variable, and. much depends upon the structure and temperature in which the plants are grown. So that the only strong evidence in favour of hybrid origin is in the changed structure of the umbel, which has become regular instead of irregular. Hence Mr. Baker did not feel justified in citing this plant as of hybrid origin when it was first presented for determination at Kew. Moreover, at that time much uncertainty surrounded the traditionary origin of the plant, and no authority could be traced for any definite parentage. But since then evidence has been gradually accumulating. The two genera have been recently crossed in at least three different gardens—and not only so, but the reverse cross has also been made by Messrs. Van Tubergen, junior, of Haarlem, and has produced a not very dissimilar hybrid. All that now remains to be done is to analyse the second generation of self-fertilized hybrids so as to determine the mutations. * As all the individuals I have seen in flower are presumably offsets from one plant, there is pr actically no variation from this formula among them. But doubtless the formula will vary in other individual hybrids. THE DARWIN CENTENARY. 227 THE DARWIN CENTENARY. THE Centenary celebration of the birth year of Charles Darwin was held at Cambridge on June 22, the date coinciding with the fiftieth anniversary of the publication of his “ Origin of Species.’”’ The Royal Horticultural Society, among other scientific societies, was invited by the University of Cambridge to send a representative to take part in the festival, and the Rev. Professor George Henslow, M.A., V.M.H., was appointed to represent the Society. The following is the text of the Address presented from the Society to the University by Professor Henslow, and appended is his account of the proceedings at the festival :— Roya HorricuLTuRAL SOCIETY, VINCENT SQUARE, WESTMINSTER, 5S.W. On our own behalf, and on behalf of the Fellows of the Society (numbering 10,500), we, the President and Council of the Royal Horti- cultural Society, send Greeting to the Chancellor and Senate of the Ancient University of Cambridge, on the occasion of their celebration of the Centenary of the birth of Charles Darwin and of the Jubilee of the publication of his great work ‘‘ The Origin of Species.” Our Society recognizes quite as fully as the University the vast impetus given to Biological Research by the laborious, painstaking, and original investigations undertaken by Darwin. We recognize, also, the peculiar indebtedness of Horticulture to this great Student of Nature, who, by the publication of his own researches and thoughts, fixed the idea of improvement by way of gradual development in the minds of thousands of gardeners, and thus set in motion a vast mass of independent investi- gations which, even if they have not always confirmed Darwin’s theories, have led to a greatly increased knowledge of some of the laws which contribute to the production of improved forms of plants. Nor can we forget the enormous debt which the horticulturists and botanists of the whole world owe to Charles Darwin for the legacy which he left at his death for the production of the work which we now know as “ Index Kewensis ’’—a work which has simplified incalculably the abour of all future investigations in dealing with species. And we feel ourselves particularly happy in being able to send this, our Address, by the hand of Professor George Henslow, M.A.,V.M.H.,F.L.S., etc., who is not only so well known by his own abundant work in the 228 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. realm of plant-life, but also bears a name revered by all disciples of Darwin, who, in his undergraduate days, was known as “the man who walks with Henslow’”’ (the father of our present Delegate), and whose appointment to the “Beagle ’’ was made on Henslow’s nomination. He also took charge of, and arranged, the collections which Darwin from time to time sent home, and of whom Darwin himself writes: “I owe more than I can express to this excellent man... my attachment to natural history, I owed in large part to him.” In token of this our Brotherly Greeting we have caused the Seal of our Society to be set hereto this 6th day of April in the year of our Lord 1909. TREVOR LAWRENCE, President. (Soctnty’s SEAL.) W. Winks, Secretary. The great Darwin celebration will long live in the memories of all who took part in it. Almost every British scientific institution of importance, the Colonies, and many foreign countries were represented. The delegates numbered 248, distributed as follows :— BritisH [suus.—79. 2 ForEIGN CounTRIES.—Germany, 80; United States, 28; France, 15; Italy, 11; Austria-Hungary, 10; Sweden, 8; Russia, 7; Holland, 6; Belgium, 5; Switzerland, 5; Portugal, 3; Denmark, 2; Japan, 2; South America, 1; Greece, 1; Norway, 1; Spain, 1; Java, 1; Egypt, 1. THE Cotonies.—India and Ceylon, 8; Canada, 7; Australia, 6; New Zealand, 6; Cape Colony, 8; Straits Settlements, 1. The first event on the three days’ programme was the Reception of the Delegates and other invited guests by the Chancellor of the University (Lord Rayleigh, O.M., F.R.S., D.Sc.) in the FitzWilliam Museum. Academic robes and orders were worn, and the former consisted of innumerable varieties of forms and colours, and with the accompaniment of the bright dresses of a large assemblage of ladies formed a picturesque scene which could not be paralleled. After being received by the Chancellor at the head of the magnificent marble staircase, the company passed into the picture galleries, which were. soon filled. By the kind permission of the Master and Fellows of Peterhouse, the college gardens were accessible from the museum. They were illuminated by Chinese lanterns and coloured lamps, and were much enjoyed, as the weather (both on the 22nd and 28rd) was all that could be desired. On Wednesday, June 23, the presentation of Addresses by the Delegates took place in the Senate House. The proceedings commenced with a short Address by the Chancellor, who, in the name of the University of Cambridge, welcomed the guests who had willingly responded from all parts of the world. “ Indeed, the occasion was no ordinary one. They THE DARWIN CENTENARY. 229 had met to celebrate the Centenary of the birth of Charles Darwin and the fiftieth anniversary of the publication of ‘ The Origin of Species.’ He was old enough to remember something of the stir caused by the latter event. To many the results of Darwin’s speculations were unwelcome, and probably remained so, at least in their application to the origin of man. Fifty years ago it would have seemed a bold prophecy to predict that day’s celebration. They might perhaps take itas proving that Cambridge was not held so fast in the bonds of Medievalism as some would have them suppose. They were prepared to face whatever strict methods of investigation might teach to be the truth. He need not remind them that on many important questions raised by Darwin’s labours opinions still differed, and he imagined that Darwin would hardly recognize as disciples some of the distinguished biologists who were met to do honour to hisname. But what appealed to all was the character of the man, loved by everyone with a spark of the scientific flame. It was a pleasure and a stimulus to think of him working on in spite of ill-health in his study, his garden, and his hothouses ; and from his retirement moving the minds of thinking men in a manner almost without parallel. He was struck, as were others, with Darwin’s wonderful modesty. This characteristic remained to the end. During the last generation Cambridge, especially since the time of Michael Foster, had been active in biological work. At the present time it was desired to establish a chair of Genetics, a subject associated with the name of Darwin and of his relative Francis Galton, and of the greatest possible importance, whether it be regarded from the purely scientific or from the practical side. He would lke to think that the interest aroused by the celebration would have a practical outcome in better provision for the further cultivation in Darwin’s own, and his son’s, University of the field wherein Darwin laboured.” After the Addresses had been presented by all the foreign delegates, Professor Oscar Hertwig (Berlin) and Professor Metchnikoff (Paris) delivered short Addresses as representatives of the Continent of Europe. Professor Hertwig regarded Cambridge as the centre of Darwin’s influence, and referred to the immense effect of Darwinian thought upon the minds of German scientists. Professor Metchnikoff similarly described the effect and extent of Darwin’s teaching in France. After the delivery of these two short speeches, the presentation of Addresses from the British Colonies and British Isles followed. Professor H. I’. Osborne (President of the American Museum of Natural History, New York City) then rose, and paid a tribute to the University of Cambridge. “To no other institution in any country,” he observed, “could they turn with such a sense of filial gratitude... . Through John Harvard of Emmanuel, Cambridge became the mother of their colleges. . . . Noble offspring, too, of the many pious foundations of the old University, of Trinity, of Christ’s, were the great men such as Harvey, Newton, Clerk-Maxwell, Balfour, and, above all, Darwin. . . . To them Darwin, more perhaps than to any other naturalist, seemed greatest in the union of a high order of genius with rare simplicity and trans- parency of thought. Dwelling on this lucid quality and on the vast range of his observations, from the most minute to the grandest relations in nature, did not the image arise of a perfected optical instrument, in 230 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. which all personal equation, aberration, and refraction was eliminated, and through which, as it were, they gazed with a new vision into the marvellous forms and processes of the living world? With this wondrous lens their countrymen, Cope and Marsh, penetrated into fossil life. Then the arid deserts of the Rocky Mountains gave up their petrified dead as proofs of Darwinism.’ At the conclusion of an eloquent panegyric of Darwin, the speaker said the American delegates, naturalists, and friends desired to present to Christ’s College, as a memorial of their visit, a portrait of Charles Darwin in bronze, the work of their country- man, William Couper, a portrait which they trusted would convey to this and future generations of Cambridge students some impression of the rugged simplicity, as well as of the intellectual grandeur, of the man they revered and honoured. Sir E. Ray Lankester concluded the proceedings by speaking on behalf of the naturalists of the British Empire. His main contention was that “in the judgment of the large majority of British naturalists, after fifty years of examination and testing, Darwin’s ‘Theory of the Origin of Species by means of natural selection, or the preservation of favoured races in the struggle for life,’ remains whole and sound and conmnene in spite of every attempt to upset it.”’ In the afternoon of the 23rd a garden party was given by the Master (Dr. Peile) and Fellows of Christ’s College in tbe college grounds. In the first court, in which his rooms were open for visitors, was also a collection of portraits, prints, and writings of Charles R. Darwin. A . printed catalogue described 257 objects, mainly supplied by his children. The fine portrait by Hon. John Collier was lent by the Linnean Society. In the evening the great banquet to the delegates was held in the New Examination Hall of the Museums building. Nearly 500 guests were present. The toast of the evening was proposed by the Rt. Hon. A. J. Balfour, as well as Dr. Svante Arrhenius, the head of the Nobel Institute at Stockholm. The Chancellor (Lord Rayleigh) was of course in the chair, being supported by the Vice-Chancellor (the Master of Pembroke), Prince Roland Bonaparte, the Rt. Hon. A. J. Balfour, the Duke of Northumberland, Sir Archibald Geikie, and other distinguished men. After the usual loyal toast ‘“ The King,” the Right Hon. A. J. Balfour, M.P., rose to propose a toast ‘In Memory of Charles Darwin.” He began by remarking that he “was conscious of but two qualifications which he possessed for the task. The one was the deepest personal affection and the most unstinted admiration for Darwin; and the second was that he yielded to no man in his loyal devotion to the University of which Charles Darwin was one of the greatest ornaments.” He then reviewed the progress of science in the direction of physical origins. Turning again to Charles Darwin he observed that “he had become part of the common intellectual heritage of every man of education, wheresoever he might live or whatsoever his occupation in life. The fact remained that to him they traced—perhaps not to him alone, but to him in the main—a view which had affected not merely our ideas of the development of living organisms, but ideas of polities, ideas upon sociology, ideas which covered the whole domain of human terrestrial activity.”’ Alluding to his personal qualities, the speaker contributed his quota to Darwin’s well-known traits by saying : ilbtieiaeatiibentntideatitiiale THE DARWIN CENTENARY. 23 “ He was sure he was not in the least going beyond the bare naked truth when he said that, quite apart from his great scientific achievements, there never was a man, never lived a man, more worthy of respect and more worthy of love than this great naturalist.”’ He concluded with the words: “He was above all a man whose heroic disposition and whose lovable qualities would, even if he had not otherwise gained that im- mortal niche in the temple of fame, still commend him to every man who either knew him personally or who by tradition had been able to form some estimate of the rare qualities which he exhibited.” Dr. Svante Arrhenius also spoke to the toast. After alluding to the ideas of Evolution entertained by the Hindoos, in Egyptian legends, Ovid’s ‘Metamorphoses,’ and elsewhere in antiquity ... “the epoch-making word was delivered by Charles Darwin in his ‘Origin of Species.’’’ He concluded an eloquent speech with the words: “In this veneration of Darwin’s memory all men of science regarded him not only as an ideal man of science, but as a man of science whose power and influence had been enhanced by his integrity and moral worth.” The toast was drunk in silence. Mr. W. Erasmus Darwin responded in an admirable reply, dealing more especially with his father’s private life in connection with his family, of which he gave his own reminiscences, which added to the well-known character affectionate traits not usually mentioned in the literature of his life. Another trait was his father’s horror of anything like cruelty, and _ he spoke of occasions in which he took an active part in suppressing it. Professor Poulton, of Oxford, proposed ‘‘ The University of Cambridge,” and the Vice-Chancellor replied. On the third and last day Honorary Degrees were conferred on twenty-one of the delegates. The Public Orator, Dr. Sandys, introduced each of them, recounting in Latin the various services they had rendered to science, for which they were to receive the degree of D.Sc. Subsequently Sir Archibald Geikie delivered the Rede Lecture on “ Darwin as a Geologist.”’ 232 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. BOOK REVIEWS. “The Face of the Earth.” By Eduard Suess. Translated by Hertha B. C. Sollas under the direction of Prof. W. J. Sollas. With numerous maps and illustrations. 3 vols. 8vo., pp. xil + 604; vi+ 556; vii + 400. (Clarendon Press, Oxford, 1904, 1906, 1908.) 25s., 25s., 18s., net. Science among English speaking peoples owes an enormous debt to the delegates of the Oxford University Press for the admirable translations of standard works in foreign tongues which are published from time to time by them. That debt has been greatly increased by the publication of Prof. Suess’ classical work, Das Antliiz der Erde, done into English by Miss Hertha B. C. Sollas under the direction of Prof. Sollas, Professor of Geology in the University of Oxford. Three volumes le before us teeming with interest to all who would learn something of the structure of the earth on which we live and of the manner in which it has been built. Many, perhaps, bearing in mind the great amount of work done by slowly or swiftly moving water acting over long periods, and of other slowly acting agents gradually changing the face of the earth, have neglected to consider those enormous forces which must have been at work leading to the making of tremendous mountain chains with their contorted and displaced strata. That deficiency the present work makes good. The first part of the book (to p. 179) deals with the movements which have taken place in the outer crust of the earth and the causes which have brought them about—with -deluges, those great floods of which legendary history so often speaks, and which in times of great seismic disturbances must frequently have reached huge proportions compared with those of which we have distinct historical records—with dislocations causing through various pressures, folding of strata, over-thrusting and such ike—with volcanos and with earthquakes. Then follows a series of descriptions of the various mountain ranges of the world and their history sketched by the hand of a master; and then a long discussion of the changes of form which have taken place in the surface of the sea. The fourth and last part, “‘The Face of the Earth,’ summarizes the preceding parts and “brings into relation the terrestrial changes which are deduced from them, with the changes which have taken place among the terrestrial faunas of the Northern Hemisphere since the beginning of the Tertiary period.” In such a work as this, parts of course, through the march of explora- tion, get out of date, but all the great discoveries in Africa and Central Asia, etc., which became available during the progress of the work are incorporated in it and, except, perhaps, for extended knowledge of the Antarctic Continent and the bed of the Oceans, investigations which are being pushed forward rapidly, the different parts of the work are only likely to need some modification in detail. BOOK REVIEWS. 2338 The translator and editor have interpolated nothing in the text, and for this abstention they deserve our thanks, for the result has been to give us a master’s conclusions based upon comprehensiveness of detail and an accuracy of observation such as one man is rarely able to combine, in English singularly free from that Teutonic form which is so difficult to avoid in translating from the German. The result is a work which every geologist must read and the conclusions in which he must weigh with all due care and reverence. ‘The maps, plates, and other illustrations —many of the last woodcuts—are admirable. ‘“ Mendel’s Principles of Heredity.’’ By Professor W. Bateson, M.A., F.R.S., V.M.H. 8vo., 396 pp., 3 portraits, 6 plates, 23 figs. (University Press, Cambridge, 1909.) 12s. net. This volume must be considered as the best and most authoritative text book of Mendelism that has yet been published. Ti contains a short biography of Mendel and translations of the two important papers (on Hybridization and on Hieraciwm) upon which the whole structure of Mendelism is founded. There is a long bibliography and a summary of the various characters (61 pairs) which have been the subject of experiment. Some of the chapters, such as those on com- pound characters, on heredity and sex, on double flowers, and on heredity in man may interest horticulturists, but the most important in this respect are the five chapters entitled ‘“‘ Heredity in Colour’’ and the one on “ Practical Applications.” By way of showing the importance of breeding from the first crosses the author gives a beautiful plate illustrating the extraordinary variations in the second generation in the case of two strains of Primula sinensis. The first cross was a dull and uninteresting flower, but in the second generation many of the blooms were richly coloured and showed in- teresting variations. The rest of this chapter deals with breeding from single seeds and with precautions against insect pollination. There are full accounts of those valuable experiments of Miss Saunders and Miss Wheldale which have greatly advanced our knowledge of flower-colours. It would be gratifying to know if other experiments are being carried out not so much in support of Mendelism as to increase our information on this important subject. There are also the interest- ing experiments of Prof. Bateson himself, who found that a richly coloured sweet pea of the ‘‘ Purple Invincible’ type resulted from a cross of two white sweet peas both entirely without colour. We have not discovered any reference to Mr. Hurst’s experiment with Golden Queen and Fireball tomatos which is one of the clearest and most interesting in this connection. On the other hand, Mr. Hurst’s suggestion that the “presence of something ”’ is usually the dominant and its absence the recessive character is, aS we are glad to observe, frankly accepted by Prof. Bateson. It is not too much to say that for all who are interested in the hybridizing of flowers, these chapters on colour are of the first im- portance. But it is at least probable that those who try to understand and appreciate them, must be prepared for severe mental exercise, for VOL. XXXV. R 234 JOURNAL OF THE ROYAL HORTICULTURAL SOCIRKTY. Prof. Bateson is a convinced and thorough Mendelian and his terminology is formidable. The work would surely have been not only more useful but more lucid and even more thoroughly scientific if Prof. Bateson had translated his heterozygotes and allelomorphs into the simple English language. Had he done so, he would have avoided certain scarcely justifiable expressions regarding Prof. Pearson and the Biometricians, and might then have been not only more lucid but less rash in -his conclusions. Thus it is not, for instance, obvious to the ordinary mind that colour- blindness must be always inherited through the mother, even although in thirty-eight cases the sons of colour-blind fathers possessed normal sight. Then again we find on page 127 “‘ whereas in all cases of sensible allelo- morphism, the number of classes is three only, two being homozygous and one heterozygous.” There is nothing new in the idea that children may inherit one special characteristic from either father or mother or ina blended form from both parents. Even in ordinary cases, such as that of the Bassett Hounds, it is certainly not one pair of characters but a great number which are in question. ‘These may be independent or they may be correlated in many intricate ways. The author’s own formula (given on p. 60) j is not very clearly stated but it is enough to show that even with only twenty pairs of characters the types amount to so portentous a number, that they become quite unworkable in practice. “Darwin and Modern Science.’’ Edited for the Cambridge Philo- sophical Society and the Syndics of the University Press, by A. C. Seward, Professor of Botany in the University. Five illustrations, 8vo., 595 pp. (University Press, Cambridge, 1909.) 18s. net. The centenary of the birth of Charles Darwin and the fiftieth anniversary of the publication of the “Origin of Species”’ has been fittingly commemorated by the production of this interesting and valuable book. The Cambridge Philosophical Society, and the Syndics of the University Press have certainly been excellently advised in adopting this method of signalizing a great scientific landmark. The volume consists of twenty-nine essays written by distinguished foreigners, Cambridge men, and a few others. There is first an intro- ductory letter by Sir Joseph Dalton Hooker. The other articles are as follows :— “Darwin's Predecessors,’’ by Professor T. Arthur Thomson (Aber- deen). No one interested in the history of evolution can afford to neglect this contribution, which is one of the most valuable in the whole volume. It is full of information not easily obtained, and written in a clear and interesting manner. “The Selection Theory,’ by Professor August Weismann, contains much that is new and unexpected. We cannot resist quoting in full the following prescient passage. “ Thus everything which we can see in animals is adaptation, whether of to-day or of yesterday or of long gone by ; every kind of cell, whether glandular, muscular, nervous, epidermic or skeletal, is adapted to absolutely definite and specific functions, and BOOK REVIEWS. 935 every organ which is composed of these different kinds of cells contains them in the proper proportions, and in the particular arrangement which best serves the function of the organ ; it is thus adapted to its function.” “ Variation,’ by Professor Hugo de Vries (Amsterdam), is of course concerned chiefly with mutants and fluctuations, and with the external and internal causes of variability. He also insists upon the importance of breeding from single seeds, especially in the case of cereals. “ Heredity and Variation in Modern Lights,” by Professor W. Bateson. This paper is for the most part Mendelian. The author goes so far as to say : “ In the experimental methods which Mendel inaugurated we have means of reaching certainty with regard to the physiology of heredity and variation upon which a more lasting structure may be built.” We think that the author has elsewhere withdrawn the statement (on p. 98) with regard to inheritance of colour-blindness. “The minute Structure of Cells in Relation to Heredity.”’ Professor Edward Strasburger (Bonn) in this brief but lucid article sketches the chief modern discoveries in cell-theory. He also shows that Darwin’s idea “that invisible gemmules are the carriers of hereditary characters and that they multiply by division has been removed from the position of a provisional hypothesis to that of a well-founded theory.” “The Descent of Man,” by Professor G. Schwalbe (Strassburg). This article is an appreciation of Darwin’s book in the light thrown upon ~ the subject by modern researches. There is, however, a short account of the possible ape-like progenitors of mankind. “ Darwin as an Anthropologist,’ by Professor Ernst Haeckel (Jena) consists also mainly of an appreciation of Darwin’s work. There is some severe criticism both of Weismann and of De Vries, but the works of Roux and Semon are highly praised. Professor Haeckel also gives full details of his present views on the subject. “Some Primitive Theories on the Origin of Man.” In this article Mr. T. G. Frazer gives a very readable and valuable account of the theories of savages on this important subject. Some tribes, according to the author of “The Golden Bough,” are crude evolutionists whilst others uphold Genesis. “ Darwin and Embryology.” The theory of recapitulation is, accord- ing to Professor Sedgwick, still without satisfactory proof. All organ- isms possess the property of reacting to the environment and of under- going a change which alters the relation of the organisms to the old environment and places it in a new one. “The Palaeontological Record as Regards Animals’ is not so hope- lessly incomplete as Darwin believed, according to Professor W. B. Scott (Princeton). The genealogy of elephants, of the rhinoceros family, of whales, and of the inevitable horse are all described in detail. “The Palaeontological Record for Plants” is by Dr. D. H. Scott. This is really the story of the successive ascendency of a series of dominant families, each of which attained its maximum in organization as well as in extent, and then sank into comparative obscurity. The flowering plants are traced backwards through the cyead-like forms of Mesozoic times to primitive fern-like seed-plants, from which the Gymno- Sperms are also derived through, at least in some cases, the Cordaiteae. R 2 236 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. For the clear and plain way in which this complex history is given in a few pages one can hardly be too erateful. Dr. Scott shows that morphological characters are sometimes adaptive, and questions the theory of mutations, “ the last resort of the phylogenetically destitute.” “The Influence of Environment on the Forms of Plants,’ by Professor Klebs (Heidelberg). For Sempervivum he finds that with strong light and vigorous carbon-assimilation a considerable increase in the supply of water and nutritive salts produces active vegetative growth, but a decrease in water and salts results in active flower-production. “ Hyery experimental investigation shows that the fluctuation of characters depends on fluctuation in the external factors.” “ Abnormal developments of all kinds in stems, leaves, and flowers may be produced by parasitic insects, fungi, or by injury.’’ These few extracts will serve to show the value of this important contribution for all practical horticulturists. “Experimental study of the Influence of Environment in Animals,” by Professor Loeb (California). The author gives his curious experiments in hybridizing sea-urchins with molluscs, &c. There is also much concerning the effect of light, gravitation, and temperature, especially on Copepoda, butterflies, and sea-urchins. He considers that every species has its own specific nuclear material or nuclein. “The Value of Colour in the Struggle for Life,’ by Professor E. B. Poulton, describes in detail every kind and form of mimicry. Most of his instances are taken from butterflies or other insects. “Geographical Distribution of Plants,’ by Sir William Thistleton Dyer. Darwin’s original views are very thoroughly discussed and con- trasted with those of Bentham, Hooker, and Wallace. There are also many interesting quotations from Guppy’s recent work and some remarks on the influence of the Glacial period on the European Flora. “ Geographical Distribution of Animals.’ Dr. Hans Gadow shows that this is nothing less than the history of the evolution of life in space and time. He attempts to reconstruct the geography of the successive geological epochs and deals with such difficult questions as convergent species, adaptation, &e. “Darwin and Geology,’ by Dr. T. W. Judd. This article is almost entirely an appreciation of Darwin considered as a geologist. ““Darwin’s Work on the Movement of Plants.” Dr. Francis Darwin, in this brief but interesting and important essay, describes the statolith theory of geotropy, sleep movements, circumnutation, and other physio- logical phenomena in the light thrown by recent researches. “The Biology of Flowers,’ by Professor Goebel, is concerned chiefly with self- as contrasted with cross-fertilization, with cleistegamy and heterostyly. It is also for the most part a study and appreciation of Darwin’s work. “ Mental Factors in Evolution.’’ Dr. Lloyd Morgan’s contribution is psychological. “The history of man’s higher progress has been mainly the history of man’s higher educability, the products of which he has projected on to his environment. This educability remains on the average what it was a dozen generations ago; but the thought-woven tapestry of his surroundings is refashioned and improved by each succeed- ing generation.”’ BOOK REVIEWS. 23% “The Influence of the Conception of Evolution on Modern Philosophy,” by Professor Hoffding (Copenhagen). It is sincerely to be hoped that every clergyman of every denomination will read, mark, and inwardly digest this valuable article, but we give up any attempt to review it. “Darwinism and Sociology.’”’ Professor Bouglé (Paris) shows how writers holding the most different opinions all refer to Darwin for proof of their very various conclusions and have all been stimulated by the evolution theory. “The Influence of Darwin upon Religious Thought,” is by P. N. Waggett, M.A., 8.S.J.E., who considers that it has been of value in three ways. These are: Encouragement of the Evolutionary Method in theology, Recoil of Christian Apologetics towards the ground of religious experience, and Restatement of the doctrines of Creation and Divine Design in Nature. Cambridge is still, we suppose, a seminary of religious education and it seems curious that no other Anglican Theologian has been asked to contribute to this volume. “Darwinism and History.’’ Professor J. T. Bury shows the in- sufficiency of general laws to account for historical development. He describes Lamprecht’s theory regarding ages of changing “psychical diapason ’’ (Spirit of the Times ?). There is also an elaborate analysis of the effect of Darwin on historical study. “The Genesis of Double Stars,” by Sir George Darwin, K.C.B. This is one of the most interesting contributions; the story of the evolution of a planet is put so clearly that it becomes, as the author claims, a fascinating study which leads the reader to the very confines of our present knowledge. “The Evolution of Matter.’ Mr. W. C. D. Whetham succeeds in explaining the new discoveries in radio-activity so clearly that the “educated layman ”’ can not only understand these complex questions but is sure to realize their importance. From these various extracts it will be seen that this book is an extraordinarily valuable one and ought, as it is intended, to appeal to the “educated layman.’ One should also mention that in the event of the volume being a financial success, the Syndics have agreed to hand over the profits to a University Fund for the endowment of biological research, which of course makes one hope that it will prove very successful indeed. It would be prudent to venture nothing in the way of criticism, for obvious reasons. Nevertheless it is surely the duty of a reviewer to be brave and to omit nothing which ought to be mentioned. We wish that several of these articles did not so much remind us of the sermons of those ministers who, in bygone years, believed implicitly in the plenary inspiration of the Bible. Darwin would undoubtedly have vigorously objected to this manner of using his work. Nor can we pass over altogether ‘‘ The Influence of Darwin on the Study of Religions’ by Miss Jane Ellen Harrison. There is a valuable Science of Religions, but it requires in the student a serious and broad-minded spirit. We find in this essay such remarks as “religious phenomena result from two delusive processes.’’ We have failed to discover any proof that 238 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY the author has realized the responsibility of writing on such a subject. Nor do we think that any just idea of the scientific study of religions can be derived from its perusal. “Germ Life: Bacteria.’ By H. W. Conn. Sm. 8vo., 206 pp. (Hodder and Stoughton, London, 1909.) 1s. net. Some years ago a little book entitled “Story of Germ Life’’ was published by Messrs. Newnes. The present is a reissue with a slightly different title, unaltered so far as the type goes, printed on paper of a different quality and with rather wider margins. The book is a useful one but here and there requires revision in order to bring it up to date so as to include more recent work. ‘The Balance of Nature.” By George Abbey. 8vo., xlvii + 278 pp. (Routledge, London, 1909.) ‘7s. 6d. net. The principal wild mammals, birds and reptiles of England are briefly described in the first part of this book, classified under the headings “ bene- ficial,’ “ neutral,’ and ‘‘ harmful.’’ The second part is devoted to methods of scaring and trapping the harmful animals and birds, and this part seems to have provided the raison d’étre of the book. A third part is given up to a brief consideration of some domesticated animals, useful as destroyers of vermin. ‘The text is for the most part accurate so far as the facts dealt with are concerned, but the expressions made use of are often of peculiar (and sometimes ungrammatical) construction, rendering the book difficult to read. The illustrations, 150 innumber, are described as diagrammatical. It seems very doubtful whether a diagram of a teal, or of a roebuck, or a sparrow-hawk perched in a most uncomfortable position, is very helpful to an understanding of the text, and, though some of them are not without humour, it cannot be said that the book would have been of much less value without them. “Life and Matter.” By Sir Oliver Lodge. 2nd Hdition. 68vo., 106 pp. (Williams & Norgate, London, 1909.) 6d. net. This well known little book now appears in paper covers. ‘The chapters are the same, but, as the author says, ‘‘ to some extent simplified.” There is also a useful “ Appendix consisting of definitions and explanations of technical and philosophical terms.” But the most important change is in the preface. In the first edition the author wrote: “Incidentally it attempts to confute two errors which are rather prevalent :— “1. The notion that because material energy is constant in quantity, therefore its transformations ... are not susceptible of guidance or directoral control. “2. The idea that the specific ounce power which we call ‘life’ is one of the forms of material energy,” &c. In the present edition Sir Oliver says: “It aims at upholding the theses :— “J. That the conservation of energy is quite consistent with its guidance and control. “2. That life isa guiding and directing principle, and not one of the forms of energy.”’ BOOK REVIEWS. 239 This way of stating the case—viz. of establishing a “ Positive ’’ instead of a ‘‘ Negative ’’—is decidedly preferable. Sir Oliver thus upholds the conception of “ Directivity ’’ which is observable throughout the whole of the organic world. “The Vegetation of some disused Quarries: The Conquest of New Ground by Plants.” ByS.Margerison. 8vo., 52 pp. (Gaskarth, Bradford, 1909.) 3s. This is an admirable brochure, with thirty-three photographs of different aspects of the quarries, &c. It is an excellent ecological exposition, showing the stages of development, including successive extinctions of the first invaders, to the quasi-permanent establishment now existing. He also shows how the same species, e.g. ling, may assume different habits and also structures according to the spots in which it has found a more or less permanent home. We have often noticed various forms of ling on a fishmonger’s stall when grouse is in season. “Oecology of Plants. An Introduction to the Study of Plant Com- raunities.” By Eug. Warming, Ph.D., assisted by M. Vahl, Ph.D. Prepared for publication in English by P. Groom, D.Se., and Dr. I. B. Balfour, F.R.S.. 8vo., 422 pp. (Clarendon Press, Oxford, 1909.) 8s. 6d. net ; morocco, 10s. net. No student of Ecological Botany can neglect this most important work. Since ecology means the application of physiology to plant life, with a complete study of external and internal morphology, with the sole object of discovering the adaptations of every histological detail, even the most minute, to the plant’s own requirements, it is at once seen that it covers the whole plant world as it exists in nature. This necessitates numerous divisions and subdivisions of the subject. Hence this great volume contains seventeen “sections’’ embracing thirteen classes [Classes IV. and VIII. seem to be misplaced; pp. ix. x.], and including 100 chapters in all. The author begins’ with “Oececological Factors and their Action,” requiring twenty-one chapters. ‘‘Communal Life”’’ requires five chap- ters. Then follow clusters of chapters on Hydrophytes, Oxylophytes (on acid soils), Halophytes, Lithophytes, Psychrophytes (cold soils), Psammophytes, Hremophytes, Chersophytes (waste lands), Psilophytes, Savannah formations and Sclerophyllous formations (bush and forest), Coniferous formations and Mesophytes. The last “section” deals with the Struggle between Plant Com- munities, the hundredth and last chapter being on the “ Origin of Species.”’ This chapter has only a little over five pages; brief paragraphs deal with the views of Darwin, H. de Vries, Vesque, and Lamarck. Darwin has ten lines, terminating with the sentence:—‘“ This explanation [by Natural Selection] has recently been assailed on many sides, and does not now find SO many supporters as it had when first promulgated by Darwin.”’ Readers of Dr. Warming’s works, such as Lagoa Santa, will be familiar with the fact that he entirely puts “ Darwinism’”’ on one side, seeing—as all plant ecologists do—that Darwin’s own alternative (first given us in his “ Animals and Plants under Domestication,” vol. ii., p. 271), that new P40 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. species arise by a response in the organism to the “ direct action of changed conditions of life, without the aid of Natural Selection,” is the true and only method which nature adopts for the making of new varieties and species. “The Encyclopedia of Gardening.’ By T. W. Sanders, F.L.S. Thirteenth Edition. 8vo., 466 pp. (Collingridge, London.) 3s. 6d. net. A book that has passed through twelve editions cannot require much recommendation. The author states that it has been thoroughly revised ; and in an introduction starting from the garden of Eden, down through the ages, there is a very good réswmé indeed of gardening and gardeners. Even Noah, we are told, “ experienced delight in cultivating the vine”’ ; truly he did, and drank too much of the wine he produced. The author rapidly surveys the history of gardeners down to the last century; and the work of such men as Thomas Andrew Knight, John Claudius Loudon, Sir Joseph Paxton, Charles Darwin, Dr. Lindley, Dr. Masters, and many others, is gratefully acknowledged. The book itself is to be commended for its cheapness: it is on the lines of Nicholson’s “ Dictionary of Gardening,” but that is beyond the means of many gardeners and amateurs; whereas anyone who cares to purchase books at all may afford the small sum required to purchase the work in question. In looking through the volume there is not much to object to—if one may except the cultural remarks, which are rather too definite. Thus under the heading of Cattleyais this advice, “ Water three times weekly March to August; once weekly August to November, and February to March; once a month other times. Temperature, March to September 65° to 85°. September to March 60° to 70°. Resting period, winter.’ Now as to watering. A plant, whatever may be the genus, should only be watered when it is in the right state to need it; it is acting by square and rule to tell a cultivator to water once a month, once weekly, or three times weekly, at certain periods; if this were all, any novice could water Cattleyas; nor do they all rest at the same time in winter. They rest when growth is completed, and the best time to repot them is not in winter; but as soon as roots begin to push out from the base of the last formed pseudo-bulbs. This instruction as to watering is also given under Phalaenopsis. “ Water daily March to April. Once or twice a week October to March.’’ Probably April is a misprint for September, but it ought not to be in a thirteenth edition. The cultural remarks in other respects are suchas may be depended upon, but in watering no one can advise the number of times any plants should be watered; climate, temperature, and the compost in which the plants are growing must be considered. To illustrate this: we sent on one occasion some Auriculas to an amateur, and, calling there subsequently, the gardener asked me why the Auriculas I sent required watering every day, while their own stock required it once in three days only. I could only account for this by more ample drainage or more porous soil in the set requiring most water. As a work of reference, for short instructions as to culture, and the natural order of genera, as well as the usual informa- tion required by gardeners and amateurs in their work, this book will be found a useful addition to the library. BOOK REVIEWS, 241 “The Book of Nature Study.’”’ Edited by J. Bretland Farmer, D.Sc., F.R.S., assisted by a Staff of Specialists. Vols. I. to IV. 8vo., 212 + 222 + 228 + 210 pp. (Caxton Publishing Co., London, 1908-09.) 7s. 6d. net. each. This book, which is being issued in six volumes, is composed of contributions from ten scientists, all of them experts on the subjects on which they write. The first two volumes, which are those now under review, deal with the animal world, and treat of the habits and structure of animals and the reasons for the difference between various animals in form and coloration, though each is made on a very similar plan to the others. ‘The work is written primarily for the use of teachers, but it will be found to be very interesting by those who have a love for natural history, but have not had any definite instruction. In the preface the editor speaks of nature study in the following terms: “Amongst the studies that deserve to take a high rank in the educational subjects, that of nature study ought to occupy a high place, especially in the case of young people. It is concerned with all the phenomena of the world _ around us, and its problems are those which confront us everywhere in our daily life.”’ The first chapter opens with four questions which are asked by naturalists when studying an animal or a portion of one. The first, what is this? Second, how does it act? Thirdly, whence is this? Fourthly, how has this come to be as itis? It is a great pity that the majority of collectors, when they have found an addition to their collection and have answered the first question to their satisfaction, are quite contented and do not take any trouble to answer the others, and except the names of their specimens cannot tell you anything about them. Such persons do not in any way deserve the title of naturalists: They only collect natural history objects in the same manner as persons collect stamps, &e. It is really much better to know something about an animal or plant, and not to know its name, than to know its name and nothing else about it. Of course it is important to know the name of a specimen, as otherwise it is difficult to make others understand what animal or plant you may be alluding to ; and those persons who spend their time in naming things and in deter- mining in what sequence they should be classed are doing very useful work, and are rather to be pitied as they spend their lives over such dry details. This work is a most interesting one, and suggestive of how the study of nature should be carried on even in channels which are not here indicated, and should have the effect of stimulating the reader to study natural objects instead of merely collecting them. After this preliminary matter a chapter follows on ‘“‘ Mammals or beasts of the field,’ giving their chief ~haracteristics and showing how they differ from others, and the peculiarities of certain types. Birds are then described much in the same manner. Some interesting figures are given showing the formation of feathers and the arrangement on the wings. The frontispiece is a dissected model picture of a vigeon, consisting of four coloured pictures placed one over the othei: the uppermost one shows the bird as usually seen, the next represents it plucked, the third the skeleton, and the last the internal organs. This model shows the 949, JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. whole structure of a bird very clearly. There are also several figures of birds, their eggs, &c. The reptiles naturally follow the birds, and then the amphibians. Figures are given of the transformations of frogs in various stages. With the fishes the account of the vertebrates closes. Earth-worms and some insects are the subjects of the later chapters, the wasp being taken as the insect to be described in detail and figured. Other insects are mentioned in the second volume, bees, ants, gallflies, aphides, and gnats sharing the honours. Centipedes, millipedes, spiders and mites are not forgotten. Snails, slugs, and fresh-water mussels are the subjects dealt with in two chapters, the latter being illustrated by a “dissected model”’ given as a frontispiece to the volume. Plants - and animals which may be reared in a fresh-water aquarium have each a chapter and many figures devoted to them. Various inhabitants of the sea are then described, and a chapter on the haunts of animals completes the second volume. Vol. iii. contains chapters 1 to 4, written by Miss Laurie, on “ The Life and Growth of the Shoot from the Bud’’; “ The Growth of Plants independently of Seeds’’; The importance oe Hairs in Plant Life” ; and chapters 5 to 7, by Dr. Lang, on “ Some Common Flowering Plants,” e.g. Spring il gavete and Karly Summer Flowers.” Several of the statements made in connection with the pork of the chloroplasts are somewhat loose, mainly through an endeavour to avoid circumlocution. : The chapters on the “ Growth of Plants independently of Seeds”’ and on “ The importance of Hairs in Plant Life” are excellent. The second part by Dr. Lang should have come first, just as the examination of common plants should precede the study of the seedling and physiological processes and their effects upon plants. The flowering plants described are among the commonest of the country-side. The writer lays great stress upon the study of their life- history and their ecology. Technical terms are used judiciously; the diagrams are very clear and distinct ; the coloured illustrations, although few in number, are exceedingly good. Those who wish to obtain an introduction to botany might well make a start with this book. Volume LV. is in three sections :— Section I. deals with “Some Common Flowering Plants,” by Dr. Lang, and is a continuation of Vol. III. Among the plants described are the cow parsnip, the potato, the foxglove, the heather, the rose bay willow herb, the dodder, and the mistletoe. Section II. consists of chapters on ferns, mosses, fungi, lichens, moulds, yeast, and bacteria, by Dr. Cavers. ; Section III. on ecology, by Miss Laurie, describes woodland vegeta- tion, plant associations, and the vegetation of commons, heaths, and moors. The illustrations, particularly those in Section III., are very fine indeed, and of great assistance to the text, whilst the diagrams in Section IT. are a delight to follow, they are so beautifully clear. We think Miss Laurie has excelled herself in the ecological section, whilst those sections written by Doctors Lang and Cavers made us wish we had had their valuable help when we commenced our botanical studies. BOOK REVIEWS. 243 As an elementary book it stands far above anything we have ever read. The authors and the publishers are to be congratulated. “Trees: a Handbook of Forest Botany for the Woodland and the Laboratory.’ By the late H. Marshall Ward, Sc.D., F.R.S. Edited by Professor Percy Groom, D.Sc. 8vo., 808 pp. (University Press, Cam- bridge, 1909.) 4s. 6d. net. This extremely interesting book, which is profusely illustrated, is of particular value in that the strictly botanical portions are written in such a popular manner as to be readily understood. The work is crammed full of information about the forms and habits of our commonly cultivated trees and shrubs, with an appendix on seedlings, and is certainly the best book between the popular and scientific work that it has been my pleasure to peruse. Hxtremely interesting are the notes on tendrils, the functions of bark, and branching, while the short accounts of our trees and shrubs are remarkably accurate and to the point. That the Austrian pine is not always readily distinguished from the Scotch pine, as stated in the work, is surely an error, for the shaggy habit of the one compares markedly with the refined appearance of the other. The bitter-sweet (Solanum Dulcamara) does not always die far back in the winter, and often far exceeds the height of 3-6 feet given in the description. But these are minor mistakes, and we strongly advise every lover of our trees and shrubs to procure a copy. “The American Apple Orchard.” by F. A. Waugh. 8vo., 215 pp. ‘(Kegan Paul, London, 1908.) 5s. Although this book was written for America we can strongly commend it to British readers, and especially to those about to embark on fruit culture on commercial lines. We have seldom seen a more instructive and practical work. Soil and situation make vast differences, and although the black loam on the eastern slopes of the Alleghany Mountains is famed for its excellent orchards, there are many black soils in Britain quite unsuited for apples; but all other soils mentioned by the author are found in abundance in this country, and will grow apples well. Mr. Waugh deals in a very clear manner with the advantages and otherwise of wind breaks for fruit plantations, and the advice on starting an orchard is excellent. Supplemented by a useful table of the quantity of trees required for an acre at various distances, orchard cultivation, and the methods to be employed, fill two large chapters, and contain much information well worth the study of all fruit growers. On the vexed question of pruning some capital instruction is given, and the objects of pruning are well stated. The chapter on the feeding of the trees ought to be carefully read. The same applies to the chapters on insect pests, diseases, spraying and solutions for spraying, though fortunately we have not to contend with all the pests of American orchards. Much of the information on gathering and packing the fruit is not applicable to this country, still a good deal may be learnt in the chapter devoted to this important matter, and we would particularly commend to fruit growers the following sterling advice : “Select a few varieties only; choose standard market sorts ; choose 244 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. only hardy healthy varieties; plant no novelties or oddities.” Such words of wisdom deserve to be brought before every fruit grower in large type. The selection of varieties given by Mr. Waugh is of course quite unsuited for this country. ‘“ Chrysanthemums: a Manual for Exhibitors and all Growers of the Queen of Autumn Flowers.” By R. Barnes. 8vo., 112 pp. (Maclaren, London, 1909.) 2s. We think the writer of this manual has been very sensible in not giving long lists of varieties that may be quite out of date in a few years’ time, but instead has paid more attention to the propagating, potting, manuring, taking of buds, insect and fungoid pests, and other matters of importance, not omitting the useful summer flowering varieties. The book is practical, and of a very convenient size. “The Royal Gardens Kew: Historical and Descriptive.” By W. J. Bean. 4to., 222 pp. (Cassell, London, 1908.) 20s. net. | A book on Kew, the finest botanic garden in the world, must be no easy task, yet Mr. Bean has treated his subject in a masterly manner and in his usual thorough style. In the opening part the early history of Kew, its ebbs and flows, successes and trials, are well displayed, but under the directorship of Sir William Hooker, Sir William Thiselton-Dyer, and the present director, Colonel Prain, Kew has become a great national garden of which all Britons are proud. In the second part the landscape, the formal and architectural features, the avenues, lawns, vistas, wild garden, water garden, rose, bamboo, rhododendron, azalea, and other gardens are admirably described. In part three the scientific side of Kew is equally carefully dealt with and the famous North Gallery and the interesting museums. Part four is devoted to the glass erections at Kew and their many and diversified occupants, while the fifth and last part is taken up with the gardens of hardy plants, such as the arboretum, pinetum, alpine and herbaceous plants, &c. In addition to an introduction by Sir William Thiselton-Dyer, the book contains twenty reproductions in colour from paintings by H. A. Oliver, and forty half- tone plates from photographs by E. J. Wallis. These, combined with excellent printing on good paper, make up a very interesting, instructive, and handsome book. ‘The Romance of Modern Geology.” By Edwin 8S. Grew, M.A. 8vo., 808 pp. (Seeley, London, 1909.) 5s. This is one of the volumes of the “Library of Romance.” The illustrations, which are beautifully clear and distinct, are a great feature of the book. The paper is not glazed and the printing large and clear, so that it is easy to read. It is a book that we wish we had read when we got our first introduction to the study of geology, for there is not a dull page from cover to cover. It begins by drawing attention to the breaking down and building up of the shore that is taking place close to home. The great denuding BOOK REVIEWS. 945 power of rivers is well shown. The state of strain existing in the earth is admirably illustrated by comparison with the modern rubber-cored golf ball. An entirely novel view of the shape of the earth without its oceans is described by the author as that of a pear-shaped body. This idea is very cleverly worked out. In fact this contrasting with known common occurrences and things to explain the unknown and in some cases difficult theory is quite a feature of the book. This is done, too, without straining. “The KHffects of Weather upon the Earth’s History,” “Records left by Rivers’? as shown in the cafions of the Colorado, “ Harthquakes, ’’ “‘ Voleanoes,’’ “The Age of Reptiles,” “‘Mammals’’ and other extinct monsters, “The Ice Age’’—these are some of the many subjects dealt with. “Plants and their Ways: an Introduction to the Study of Botany and Agricultural Science.” By Hrnest Evans. 8vo, 171 pp. (Dent, London, 1908.) 1s. 4d. This book, whilst containing some good features, is not in line with modern methods. To introduce such terms as oosphere, embryo-sac, nucellus, integuments, at such an early stage of the book as page 6 is unfortunate. We think the structure of a flower studied at an early stage should be limited to what is able to be seen with the naked eye, as far as possible, then appeal to the lens, and finally to the microscope, when the student is well advanced in botanical study. Technical terms, too, should be reduced to a minimum, particularly as the book is “an introduction to the study of botany.’ Again, to introduce the fern plant and parasites into such a class of books is wholly unnecessary. On page 87 in too briefly noting ‘“ the work done by lime in the soil ”’ the following statement appears :—“ The lime neutralizes any acid which the soil may contain and sweetens it.’ This without any previous mention of what “neutralizing an acid’’ means is a grave breach of modern methods of approach. On page 15, under the head of “ Practical Work to ascertain what is Pollen,” the diagram illustrating the pollen grain, and further on those of a “Section through an Ovule,”’ as well as “the diagram showing the ovule after fertilization,” require the use of a microscope, and hence are unnecessary in an introductory work. We should have liked to have seen the chapters on “Cultivated Plants and Common Trees ’’ and “ Plant Societies’’ more fully treated. The book seems to us to have been hastily produced in response to the great demand for books on nature study, with which, to our mind, it has very little in common. ee “Nature Rambles in London.” By Kate M. Hall, F.L.S. (Hodder & Stoughton, London, 1908.) 3s. 6d. net. The author introduces to us in a most interesting fashion Nature in her seasonal dresses in London parks. Nature as she appears in plant and animal life is charmingly described, and at the same time a large amount of information is conveyed. The illustrations, which number nearly 100, are a great feature of the book and admirably assist the text. 946 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. The idea of giving a list-of the trees and shrubs to be found in the various parks is a good one and worthy of extension. ‘“Blementary Agricultural Chemistry.” By Herbert Ingle, B.Sc. 8vo., 250 pp. (Griffin, London, 1908.) 4s. 6d. net. The writer treats very briefly, perhaps too briefly, of the Atomic Theory, Properties of Oxygen, Hydrogen, Carbon, Nitrogen, Sulphur, Phosphorus, Calcium, Potassium, Sodium, Magnesium, Iron, Chlorine, and Silicon as an introduction. The Chapters on “The Plant,” “ Manures,” “Crops,” “The Animal Body,’”’ “The Feeding of Animals,” and “The Dairy” are particularly well done. “Life Histories of Common Plants.” By F. Cavers, D.Sc. Lond. 8vo., 868 pp. (Clive, London, 1908.) 3s. ; In this book the student is skilfully directed to find out things for himself by the examination of fresh specimens, the foremost place being rightly given to physiology and ecology. The earnest student who does not mind painstaking work will appreciate this book, particularly as the necessary materials and apparatus can be obtained at a trifling cost. If he works through it he will have laid a solid foundation for a sound acquaintance with the structure and life processes of plants, and the relation of plants to their surroundings. After taking the broad bean as a type under the heads of “ Seeds and Seedlings,’ “The Green Plant’s Nutrition,” “ The Growth of Root and Shoot,’ “Buds,” “Flowers, Fruits, and Seeds,” the life histories of such plants as the sweet pea, vetches, clovers, and common repre- sentatives of the Ranunculaceae, Rosaceae, Violaceae, &c., are very well worked out. ‘‘The Life of Philibert Commerson, D.M., Naturaliste du Roi. An old- world story of French travel and science in the days of Linneus.” By the late Captain S. Pasfield Oliver, R.A. Edited by G. F. Scott-Elliot, F.L.S., F.R.G.S. 8vo., 242 pp. (Murray, London, 1909.) 10s. 6d. net. Mr. Elliot first gives us a short account with portrait of Captain Oliver aud his travels, followed by the editor’s preface, in which Oliver knowing that his death was near entrusted all the materials to Mr. Elliot, who although he says he takes “no credit’’ for his share has produced a most interesting and fascinating work. The book contains thirteen chapters, which begin by carrying us from his student days in the Montpellier Gardens and in various parts of France, till he marries and moves to Paris. Then follows some account of Louis Antoine de Bougainville—whose name is perpetuated in the well-known plant—with whom Commerson subsequently travelled. He it was who carried the terms of surrender to the British camp when Canada was definitely lost by the French (Sept. 8, 1760), aman of most remarkable abilities. The sixth chapter describes his journey to Buenos Ayres, his enthusiasm not only for botany but also fishes, about which many interesting details are given. He reaches the Spice BOOK REVIEWS. 247 Islands, and we hear a good deal of the Tahitians. They just see Austra- lia, but pass too far off in going to Mauritius, about the botany of which much is said. Then followed Madagascar, a perfect mine of wealth for his botanical enthusiasm. Here he found a race of pygmies on the mountains and compares them to the dwarf alpine plants. In the island of Bourbon, which he thoroughly investigated botanically, he found more new and curious fishes ; some good photographs are supplied of insects mimicking sticks, leaves, &ce. He died on March 18, 1773, never having lost his enthusiasm for science, and “ eight days after his death in Paris he was elected a member of the Academy of France by a unanimous vote in a full assembly. This was an honour unprecedented in the history of that body. No other savant, however eminent, had ever been elected in absence.” The final chapter deals with Commerson and his scientific work. Would that every student would read the book and try to share in his enthusiasm. ‘“Hissays, Biographical and Chemical.’ By Sir William Ramsay. 8vo.; 247 pp. (Constable, London, 1908.) 7s. 6d. net. The history of chemistry, as generally treated, quite fails to interest one who has little special knowledge in that subject. The author of this work, however, has succeeded in presenting certain periods to the general reader in a most delightful manner. The whole volume is written in non-technical language as far as possible, and where technical terms are introduced they are carefully explained in such a way that the reader with only a general scientific knowledge should appreciate the extremely interesting series of subjects dealt with. The volume is divided into two sections dealing respectively with historical and chemical essays, and throughout the author has given expression to his high appreciation of the characters of those of whom he treats, and of the value of their labours in promoting the growth of scientific ideas. Due importance is given to the life of the man, as well as to the work of the chemist. One would perhaps hardly expect to find Lord Kelvin regarded primarily as a chemist, and this may explain the rather inadequate treatment of his work. With regard to the chemical essays, subjects of recent inquiry are dealt with, and while the essay on “ What is Electricity ?’’ can hardly be described as convincing, that on the “ Aurora Borealis’”’ provides a good example of the wide range of knowledge required to enable one to attempt to explain one of the most interesting of natural phenomena, more especially to the reader of no great scientific attainments. In attempting to explain too much, the line of one’s argument is liable to be rendered indistinct, but by careful summarizing the author has to a great extent avoided this difficulty. The last essay deals with the “Functions of a University,” and will appeal to all who are in any way interested in educational matters. It emphasizes the fact that the modern university is an essential factor in the progress of industry, rather than a convenient centre for the acquisi- tion of mere knowledge or social conventionalities, and anyone who 248 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. doubts the advisability of Government support is recommended to study. the author’s arguments. “Electricity, Present and Future.” By Lucien Poincaré. Trans- lated by Jasper Kemmis. 8vo., 815 pp. (Sisley, London, 1908.) 7s. 6d. net. This work is a review of the various steps that have led up to the present knowledge and applications of electricity. The language employed is not too technical, but a good deal of technical knowledge will be required to enable one to appreciate the author’s very able and comprehensive treatment of his subject. Due prominence is given to the dependence of industry upon science, while it is shown that science has in many instances been a debtor to industry in having problems needing solution provided for her. Only a few pages are devoted to the ‘‘ Future Evolution of Electrizity,”’ and in these are indicated a few of the immense number of paths along which future developments are to be expected. | “The Perfect Garden: How to keep it Beautiful.”’ By W. P. esa : 4to., 408 pp. (Grant Richards, London, 1908.) 6s. net. This is a handsome well-printed volume, opening with a prologue on dream gardens, followed by the subjects divided into five parts. Part I. treats on the design of gardens, the cost of gardening, specialism in gardening, how to learn gardening, and the conquest of the wild. We endorse every word the author says in this part, and taking into con- sideration that the book is written chiefly for those who possess or intend making a comparatively small garden, we can advise all such to study this part carefully, especially the chapter on the cost of gardening. Part II. fills a large portion of the book, and deals with practically evéry phase of the flower garden, including colour, herbaceous plants, rockeries, roses, lilies, trees, shrubs, bulbs, garden enemies, &c. The list of plants, with their different heights and the colour of the flowers, is compiled in an excellent style, and will be most useful to the amateur gardener who may intend making an herbaceous border. The same applies to the rock plants, although only a short list of the plants available for the rock garden is given; still quite sufficient are named for any ordinary-sized rockery, and a bigger list might be confusing. Only a small portion (pp. 287-250) is devoted to the glass-houses, but this part is filled with very serviceable information. Part IV. deals with hardy fruit, and after giving instructions on how to make a fruit garden the author tells us what to plant, and here we consider too many varieties are named. In apples we should leave out Blenheim Orange because even in the Paradise stock it is a shy bearer, New Hawthornden is a bad cooker, Worcester Pearmain is a vastly overrated variety, and Cornish Gillitlower is delicious when you can get a crop, but it is one of the shiest bearers. In pears again we should omit Beurré Clairgeau, Clapp’s Favourite, Conference, Beacon, and General Todleben. Part V. is given up to vegetables; which are ably dealt with, and then follows a series of very good plans of gardens. BOOK REVIEWS. 24.9 “Golf Greens and Green Keeping.” Edited by Horace G. Hutchin- son. 8yo., pp. 219. (Country Life, London, 1906.) 10s. 6d. net. This book is made up by contributions from specialists on golf greens and green keeping, and deals with soils in various parts of the kingdom where golf is played, and owing to the varied characters of the soils the book should prove a very useful one for golf players and others interested in this popular pastime. All the chapters are admirably written, end the information is so plain that anyone may easily follow the writers’ instructions, and we would suggest that committees presiding over golf courses should give their green-keeper a copy of this book. In the next edition we would suggest a few notes being added on the best grasses to use for greens on different soils, so that the green-keeper could not only sow the grasses best adapted to his own soil, but also be able to sow seeds for producing turf to replace worn-out places. The mat grass (Nardus stricta) and Agrostis vulgaris are specially advised for seaside links and for damp ground, but little else is said about any other good grasses tO use. “Sea-coast Gardens and Gardening.’ By Frances A. Bardswell. Svo., 145 pp. (Sherratt & Hughes, Manchester, 1908.) 3s. 6d. net. A well-got-up and interesting work, based on practical experience gained by the authoress in an exposed windy position on the Norfolk coast. Some of the matter we have seen in the Garden and Country Infe, and some information is quoted from that excellent book ‘“ Seaside Planting,’ by Mr. Gaut; but we can recommend all really interested in a seaside gardening or planting to read the authoress’s experience, combined so delightfully with information she has collected from other sources. The book is nicely illustrated. “Gardening Made Easy.’ Edited by E. T. Cook. 4th ed. 8vo., 202 pp. (Country Life, London, 1908.) 1s. net. As the editor states, this is a simple handbook to the garden written for beginners, and we must say that he has achieved his object admirably. Ii would be invidious to single out any special chapters or chapter ; it will suffice to state that ornamental plants, vegetables, and fruits most suitable for beginners to choose are named, followed by descriptions of climbing plants, lawns and how to make them, the rose garden, the greenhouse, bulbous plants, the kitchen garden, the fruit garden, herba- ceous plants, &c. ; in fact, nearly everything that the amateur or beginner in gardening requires is clearly and concisely dealt with by the author. Tt is a very cheap practical book, within the reach of all. “Tllustrations of the Royal Gardens, Kew.” By E. J. Wallis and Herman Spooner. Obl. 4to., pp. 64. 1908. Is. net. Mr. E. J. Wallis has produced some beautifully executed photographs or illustrations of these famous gardens, and Mr. Herman Spooner has written most interesting notes bearing on the illustrations. Many who have visited and enjoyed Kew will be delighted to get such a charming memorial of their visit. The late Director has written a brief history of- VOL. XXXV. S 250 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. Kew and other items of interest, and we compliment Mr. Spooner on the manner in which he has written his descriptive notes, for he not only - explains the illustrations very clearly, but gives the history and habitat of many of the plants shown ; for instance, in describing Amorphophallus Titanum, he says: “It was discovered by Dr. Beccari, the illustrious traveller and botanist, in the province of Padang, in Sumatra, in 1878. Beccari at first found the leaf only, and offered a reward to the natives for a flower, and to his surprise it required two men to carry the vonderous mass. To give an idea of the dimensions of the flower in its native home it is sufficient to say that a man standing upright can barely reach the top of the spadix, and with open arms can scarcely reach half-way round the circumference of the spathe.”’ “Sweet Peas and How to Grow Them.” By H. H. Thomas. 8vo., 112 pp. (Cassell, London, 1909.) 1s.; cloth, 1s. 6d. net. A very useful little book of convenient size for the sweet-pea growers, and their name is legion, giving full directions as to how to grow them, the best varieties to grow, hybridizing, diseases, pests, in fact all one could reasonably wish to know is supplied in this well-written book. “An Artist’s Garden, Tended, Painted, Described.” By Anna Lea Merritt. Demy 8vo., 195 pp. (George Allen, London, 1908.) 21s. net. This is a beautiful book, handsomely illustrated and admirably printed on excellent paper; but its charm is, in our opinion, quite spoiled by the authoress’s attack on a very industrious, respectable, capable, and painstaking body of men. We cannot imagine a nastier term to apply to a gardener than to call him “a hireling gardener,” classing him amcngst such perversities as “insects, moles, mice, and blights of mildew and manners.” It is scarcely obvious why “gardeners ought to have wide faces and eyes far apart.’’ No reason is given why they should be different from the rest of the human race, and it seems that the writer of this book must have a very poor opinion of all gardeners, as she tilts at the wani of taste displayed by the professional gardener. Even artists have very opposite ideas of taste, and to dogmatically state that most professional gardeners are lacking in taste would not be endorsed by all other artists. “In My Lady’s Garden.” By Mrs. Richmond. 8vo., 464 pp. (Unwin, London, 1908.) 12s. 6d. net. The authoress tells us from her own experience what to do, and what to expect in flower every week for the whole year, the whole being written so clearly that no one can make any mistake as to the meaning or instruction given. In every garden of any extent ‘‘ my lady’s garden”’ is of more than ordinary interest, and we naturally expect to see good taste, neatness, and order prevailing ; and to these ends Mrs. Richmond’s book ministers in a marked degree. The information on the most beautiful flowers to grow is excellent, and the positions they succeed best in are well described. Aquatic, wild garden, herbaceous, sub-tropical, stove, greenhouse, hardwooded, and other plants are all brought under the notice of the reader in a charming manner, and the advice on laying out and ~ BOOK REVIEWS. 251 planting a garden, though brief, is very much to the point. The volume is well printed and illustrated. “Gardening in the North.” By §. Arnott and R. P. Brotherston. Svo., 272 pp. (Cassell, London, 1909.) 2s. net; cloth, 2s. 6d. net. Although this book is written for gardeners in the north, much of the information is equally suitable for those in the south. Stress is laid on the climatic conditions of the north, but there they never get the hot drying periods in summer experienced in the south; at the same time this book should prove an acquisition to the young gardener in any part of the kingdom, as it is crammed with really sound practical information on almost every phase of horticulture. The information on plants that will thrive in the immediate neighbourhood of smoky towns, will be valuable for those who do their gardening under such unfavourable conditions, and the lists of plants, fruits, and vegetables, and the calendar of operations are excellent. “Grape Culture up-to-date.’ By Alexander Kirk. 8vo., 75 pp. (Pawson & Brailsford, Sheffield, 1909.) ‘7s. 6d. net. In this latest publication on grape culture we have the experience of one of the most successful growers and exhibitors in the country, and many will welcome his book. He describes in a minute manner how his success has been attained, and we especially advise young gardeners to read, mark, learn, and inwardly digest all the sound practical instruction and in- formation given by Mr. Kirk. We believe that grape culture in private gardens does not reach such a high standard as it used to do. There are of course exceptions, but a gardener who can place large bunches with large berries well coloured and of fine flavour on his employer’s table will find himself appreciated, and should he need a situation he will gain points in the final selection of a gardener. Practically everything the grape grower under glass may wish to learn is given in this book, the capital illustra- tions being a great aid to the inquirer. The construction of vineries, drainage, compost, planting, pruning, thinning of the berries, forcing, watering, feeding, ventilation, renovating, storing, diseases, pests, &c., are only a few of the items admirably dealt with. “The National Rose Society's Handbook on Pruning Roses, 1909.” New and Revised Edition. Compiled by a Committee of the Society. (Mr. H, Mawley, Rosebank, Berkhamsted, 1909.) 2s. 6d. This little book supplies a long-felt want, as all rose growers fre- quently feel in doubt how various kinds ought to be pruned, and in this book they get the instruction required. The information on early autumn thinning of growths we particularly commend to all growers, as it improves the productive power, and also the appearance of the plants, amazingly. The errors made in pruning are pointed out very clearly. The book closes with an excellent alphabetical list of varieties. “Thirty-nine Articles on Gardening.” By Emmeline Crocker, F.L.S. Svo., 159 pp. (Dulau, London, 1908.) 5s. net. This will prove an interesting book to amateurs and. professional gardeners, as the style is pleasing, and the information on plants growing 82 952, JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY, in their natural habitat is just what is wanted by the cultivator in this country. The thirty-nine articles or chapters are too numerous to give in detail, but they cover the following and other subjects, viz. iris, alpine plants, seeds, weeds, annuals, Primulas, insectivorous plants, roses, shrubs, bulbs, sub-tropical plants, pruning, propagating, &c. We think there are too many words printed in italics; if confined to the names of plants the work would have been improved, but as it is italics are freely used for all sorts of words which the authoress desires to emphasize. However, this may be a matter of taste; many will no doubt approve of what we dis- approve. “Tntracellular Enzymes.” By H. M. Vernon, M.A., M.D. 8vo., 240 pp. (Murray, London, 1908.) 7s. 6d. net. This work will appeal chiefly to those interested in the chemical side of the physiology of animals and plants. The subject matter, however, is of very great importance to all advanced students of biology and much of the information has been collected in one volume for the first time. The book is based on lectures given at the Physiological Laboratory of the University of London. The author truly summarizes the importance of the subject by stating that it “bids fair to become, if it has not already become, one of the most important branches of biochemistry, for it alone seems to offer a clue to the solution of the most fundamental of all biological problems—the nature and constitution of protoplasm.” Observations of enzyme activity have accumulated so rapidly during the last few years that we are unable at present to clearly estimate the im- portance of the results obtained. We ‘‘ cannot see the wood for the trees.”’ This is no doubt the reason why Dr. Vernon has found it difficult to fit together fragments collected with much industry from the scientific journals of the world. Many of the results obtained by the original workers are mutually contradictory, and many more are difficult to explain. The author has endeavoured to deal critically with this mass of material, and has accomplished his task fairly and judiciously. His own original observations, which are many and important, receive the same impartial treatment. It would, perhaps, have been convenient to busy workers if the vegetable enzymes had been separated from the enzymes of the animal world, but comparison between similar enzymes inthe two kingdoms would then have been made more difficult. At present, to quote but one instance, the proteolytic enzymes of animals are much better understood than those of plants, and any worker who wishes to deal with the proteases of plants must first become acquainted with the work of animal physiclogists. Dr. Vernon has laid due stress on theoretical questions such as “the rate of enzyme action,” “reversible enzyme reactions,’ “the energy relations of reacting systems,” “the influence on reaction of temperature and of the products of reaction,’ and he has emphasized the fact that enzymes may, and often do, synthesize as well as decompose. They are factors in anabolism as well as in katabolism. The student will find the book a mine of information, but he must be prepared to dig. It is not a volume of light literature for leisure hours. Full references are given to all the most important original papers. BOOK REVIEWS. 953 “The Heredity of Acquired Characters in Plants.’ By Rey. Professor G. Henslow, M.A., V.M.H. 8vo., 107 pp. (Murray, London, 1908.) 6s. net. This little book contains the grounds upon which the learned author bases the belief he so strongly holds, that acquired characters in plants are hereditary, and that all hereditary characters have at some time or other been ‘“‘acquired.’’ He defines “ acquired characters”’ as “ any change of structure (morphological or anatomical) from the normal characters of any part or parts of a plant (z.e. in comparison with others of the same species or genus which have not changed at all) through the means of a response to some new and direct action of the external influences of the environment or ‘ changed conditions of life.’ ”’ No one who gives any thought to the question can fail to be struck with the adaptive structures exhibited by plants and by the fact that the progeny of one plant may vary greatly according to the conditions under which it is found. The assumption that plants can vary so as to acquire any adaptive character and that such acquired characters are hereditary affords an easy and obvious explanation of many of the phenomena we may observe on a country walk. Indeed, the explanation appears a little too obvious, and in reality the question is beset with difficulties, as are most questions connected with the phenomena exhibited by living things. ; Variations appear to be of two species. There may be variations in kind, so that a plant possesses a character or it does not; for instance, a pea may possess the character that makes for tallness, or that character may be absent, and the pea will then be dwarf, and with the dwarfness other characters entirely dependent upon it will be exhibited. On the other hand, variations may be in degree. A tall pea may be more or less tall, a dwarf more or less dwarf; but recent experiments seem to show there to be a mark of delimitation between the two. In this book, although here and there some hint of the existence of two species of variation is given, yet nowhere is it plainly stated that these two species exist. Very frequently one finds that plants grow where they can, not where they can grow best. There are many instances known of plants which hold their own in a certain place, but which when removed to another situation grow with such vigour as to become the dominant feature of the vegetation. We may interpret this in two or three ways, but it would appear quite probable that the plant was better adapted to an environ- ment different from its original one. That is to say, its adaptation to its environment was imperfect. It is not obvious why, if it were able to adapt itself so far, it could not adapt itself perfectly. As Darwin pointed out, there are many adaptations to environment which fall short of perfection. Why should self-adaptations to environment be impertect ? Again, there frequently appears to be no direct correlation between the habitats (environment) of two distinct varieties of a species and their characters. Not far from where we are writing one may find the common form of the ling (Calluna vulgaris) growing with its branches intertwined with the hoary variety incana. Are these both equally adapted to their environment, and if so, why did they not vary 254 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. in the game direction? In ages past one cannot doubt that en- vironment had precisely the same material to act upon—these had a common ancestor. Or is Nature, perhaps, experimenting ? The origin of variations in kind seems still to seek ; or perhaps it is only the origin of the material basis of the power to vary, and from a definite knowledge of what that is we seem to be still far off. All the book contains is worthy of careful reading and consideration ; but whatever the origin of variations may have been we are through the careful experiments of many workers being shown that for practical plant breeding the only sure method is to start with the variations shown by individual plants and to breed from individuals, not from promiscuously crossed groups of the same species. Here and there the book appears to bear the impress of having been compiled in a hurry, which could be no gain. For instance, the references on p. 94 to the plate are all wrong, and it is stated that “ Tamus communis appears to have one cotyledon ’’ when “ two cotyledons ”’ was intended. Other somewhat similar mistakes are noticed on p. 8, p. 52, and p. 53. ‘The Principles of Microscopy.”’ By Sir A. KE. Wright, M.D., F.R.S. 8vo., 250 pp. (Constable, London, 1906.) 21s. net. This is a highly technical manual intended for those who are willing to make microscopy a matter of intellectual study. Tiveryone who uses the microscope seriously should no doubt do this, but, unfortunately, the time at the disposal of most does not permit of studying the instrument so elaborately as the author would have one do, and instead the student has to be content with rule-of-thumb methods and the experience gradually gained by trial and error during the progress of his work. But for those who wish to obtain a thorough knowledge of the fundamental principles underlying the development of proper images in working with the microscope there is no better guide than the volume before us. “Pronunciation of Plant Names.” By Rev. C. Butler, M.A. Small 8vo., 94 pp. (Gardeners’ Chronicle, London, 1909.) 1s. net. The pronunciation of plant names often presents difficulties and particularly in regard to which syllable should be emphasized. With this guide to hand no one need be at loss. It is of convenient size and contains all the generic names that are likely to be met in even the largest garden.. While, unlike the admirable list in Nicholson’s “Dictionary of Gardening,’’ classical usage is departed from in some names, as Anem’one, the author has probably followed the better course in adopting the more popular pronunciation. The vexed question also as to how far local pronunciation should be followed in generic names derived from personal names is got over by retaining the local pro- nunciation, (though not always completely). Thus Halesia is Hal’-zi-a, Stokesia, Stok'-si-a, Heuwchera, Hoi’-kéra, and so on. The author does not attempt T'chihatchewra ! The list is very free from errors in the generic names themselves, though “ Absinth” (p. 1) should have been Absinthiwm, and “ Hsch- scholtzia ”’ (p. 83) was originally spelt without a “t,” as it is in “ Index BOOK REVIEWS. 255 Kewensis.’”’ The book is a welcome addition to the indispensable com- panions of the gardener, amateur or professional. “ Botany for Matriculation’? By F. Cavers, D.Sc, F.L.8. 8vo., 568 pp. (University Tutorial Press, London, 1909.) 5s. 6d. This is an excellent book of its kind, full, clear, and concise, and contains an admirable exposition of ecology. The majority of elementary text-books of preceding years dealt solely with structure with the view to classification, but since ecology has become a subject of examination, students are compelled to study plants from a new point of view. The author says in his preface: “The fact that I regard ecology and physio- logy as the aspects of plant life which should be chiefly presented to beginners will explain—and, I hope, justify—the inclusion in this book of a good deal of information which is given in works of chemistry, physics, meteorology, and geology.’”’ Looking at it from a beginner’s point of view, we think Chapter II. should have been postponed to p. 516, and precede, or even follow, the chapter on ecology; but the fact is no book on botany can be read straight through. The student studies various parts of plants as he can get them. He can study seeds in the winter, then germination in spring, &.; but ecology he can pursue at all seasons, whenever he can take a walk into the country. He thus gathers his knowledge as it is possible, and may study any part of the book before us as he requires it. The author rightly describes types, not in any +rictly classificatory sequence, but just as a student must study them in nature. There appears to be a few omissions, such as the anatomy of the msertion of stipules, an infallible clue to their origin and nature. No mention is made of the special rays concerned in transpiration, viz. violet and red; yellow and blue are rightly stated as necessary for photosyn- thesis. In answering the question, “Is light required for starch forma- tion?’’ the use of sugar in the reformation of starch in tubers, without light, might be alluded to. The author seems to still hold Darwin’s original, but not later, view of the injurious effects of self-pollination (p. 267) ; but on p. 288 he describes the special arrangements for it. The fact is Darwin made a mistake ! We can heartily recommend this book to all who will use it as a help and a guide to their study and examination of living plants. “ Aoricultural Botany.’’ By Prof. J. Percival, M.A., F.L.8. 8rd Ed. 8vo., 806 pp. (Duckworth, London, 1907.) 7s. 6d. net. This is perhaps the best book upon agricultural botany, and the fact that it has reached its third edition shows that its value has been appre- ciated by students. This edition has been further improved by a short but lucid account of the Mendelian law of inheritance. “The Bird-life of London.’ By Charles Dixon. 8vo. 335 pp. (Heinemann, London, 1909.) 6s. net. This book describes 135 species of birds as from time to time coming within the neighbourhood of London, though a few of these, as the raven and the peregrine falcon, are only of historic interest. The book is 256 - JOURNAL OF THE ROYAL HORTICULTURAL SOCIRTY. pleasantly written and shows a very thorough personal knowledge of the birds and their haunts. The introduction contains a list showing the birds that are resident, those that are summer migrants, those that are winter visitors, those seen on migration, and those only occasionally or accidentally visiting the district. Each chapter starts with the local names by which each bird is known, its distribution in Britain, and its distribution within fifteen miles of St. Paul’s. The foods, habits, and notes of the birds are described, as well as the appearance of the adults and nestlings. The illustrations of the bird, some in colour, others in black and white, are by Mr. John Duncan, of Newcastle, and though most of them are small they are very well drawn and life-like. More might have been said of making artificial nesting boxes in the London parks to encourage certain birds nesting there. The book is one of the most interesting on birds we have had the pleasure of reading. “Birds Useful and Birds Harmful.” By Otto Herman (Director of the Royal Hungarian Ornithological Bureau, Budapest) and J. A. Owen, illustrated by T. Csérgey. 8vo., 387 pp. (University Press, Manchester, 1909.) 6s. net. This book is divided into the following chapters: 1. Useful or Harm- ful. 2. Structure of the Bird. 8. Workers on ;the Ground. 4. In the Air and on the Trees. 5. The Farmer’s Summer Friends. 6. Workers all the Year round. 7. Some Wildfowl. 8. Some of the Falconidae. 9. The Rational Protection of Birds. The origin and work of the Hungarian Central Office for Onnitelaes is briefly described. It starts with the idea that nature itself knows neither useful nor injurious birds, but only necessary ones, which have developed according to the natural laws, and on the basis of their development are performing in the world of nature the work which is appropriate to their organization. Where nature is intact, the number of birds is automatically regulated in accordance with the natural development of their surroundings. The adaptability of wing, bill, foot, and feathering to the various purposes in the life of the bird is well illustrated. These two naturalists deal duly with the harm as well as the good done by birds. To English naturalists and cultivators the book would have been of additional interest if a summary had been given of the results obtained by the Hungarians in examining the stomachs of the various birds to ascertain their food and habits, and it would be of interest to know the source of some of the information, whether from Hungary or Kngland. A few of the birds described are practically unknown in England, though perhaps common in Hungary. Passing by the useful birds, we quote a few opinions on some of the birds that do a certain amount of harm; thus with reference to starlings among cherries it says: “yen the most ardent bird-lover will not be foolish enough to protect every bird at all times and seasons,’ and recommends scaring by the gun, &c.; if a long narrow flag be fixed to a strong branch on tall cherry trees these birds will be kept away. The starling has been BOOK REVIEWS. WaT introduced into South Victoria, Australia, and though useful on pasture it clears the vineyards of fruit. The blackbird was introduced into New Zealand, but now a price is put on its head and eggs on account of the damage it does to fruit. Fruit needs also to be protected from the thrush. Of the sparrow it is said: “It is true that the common sparrow multiplies too fast. Many a bird-loving landowner and farmer attempts to keep it within bounds in various ways. The late Lord Lilford declared the most humane way was to pull down all the nests within man’s reach; there would be plenty left in inaccessible places. A humane farmer in Hampshire, a great wheat grower, pays 3d. per score for all sparrows’ eggs brought to him. In a Lancashire parish the vicar encourages the jackdaw, allowing it to build even in his church-steeple, because wherever that bird is, sparrows become more scarce, their young suiting that bird’s palate well.” In the case of the rook early sowing of wheat is recommended, while there is sufficient insect food about for the birds, as the best preventive from the mischief it does in disturbing and eating the corn. A good description of the ways of the hawfinch with regard to peasis given quoted from the observation of a gardener. The injury to gooseberry buds by bullfinches, to swede and turnip seed by greenfinches, and to turnip-tops and acorns by wood-pigeons is dealt with. The book concludes with particulars and drawings of nesting boxes for the encouragement of certain birds. We can recommend the book as combining the natural history of birds with their economic habits in relation to the gardener and the farmer, . but wish the opportunity had been. utilized of giving the results of the observations on the food of birds actually made by the Hungarian Bureau of Ornithology. “ British Birds in their Haunts.’’ By the late Rev.

This attractive book gives interesting accounts and observations of the birds by the late Rev. C. A. Johns, F.L.8., with scientific classification brought up to date, together with additional facts of interest by Mr. J. A. Owen. The colcured illustrations, of which there are 256, are good representations of the birds in miniature. “Birds and their Nests and Eggs found in and near Great Towns.”’ By George H. Vos, B.A., M.B.

These little books are well illustrated by numerous photographs by the author, of birds’ nests, eggs and surroundings from life, or of good specimens of stuffed birds in natural surroundings. The author gives accounts of his natural history rambles and observations at different times of the year. At the end of each volume is a very concise synopsis of the birds mentioned, which must be the result of careful observation, dealing with points such as favourite localities, differences in plumage 258 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY, colour, size, mode of flight, manners, postures and notes, migratory habits, materials of nest, shape and size of nests, coloration of eggs, and the number of eggs ina clutch. Thus fifty-two of the commonest birds are described in the three parts, and for aid in recognition are divided into various groups. “The Cultivation and Preparation of Para Rubber.” By W. H. Johnson, F.L.S, Second edition. Rewritten and greatly enlarged. 8vo., 178 pp. (Crosby Lockwood, London, 1909.) ‘7s. 6d. net. The number of books and periodicals published at the present time which deal with rubber production are symptomatic of the interest taken in this comparatively modern industry. The book under review brings up to date the information bearing on the practical work of cultivating the Para rubber tree (Hevea brasiliensis) and preparing the raw rubber for export. As the author states in his preface, new methods of collecting and preparing rubber are frequently being evolved, and in view of the industry's comparative infancy, there is every probability that what are to-day recognized as: up-to-date or standard systems will in a few years be considered quite obsolete. The book opens with a short chapter on the history of Para rubber, its increase in value and the rapid extension of the areas devoted to Para rubber cultivation, more especially in British possessions in the East. The propagation and cultivation of the tree are next fully dealt with, the soils and manures found most suitable to its well-being discussed, and an account given of the pests (happily few) to which it is liable, and the best methods of combating them. Different planters have different methods of tapping the trees to procure the rubber- yielding latex, and arguments for and against these methods are given by the author. The treatment of the latex to procure the rubber and the various processes to which the latter is subjected before being ready for export are described in detail and fully illustrated. In this connection several machines and labour-saving appliances are figured and described, and suggested plans given for arranging a rubber factory. An interesting chapter is that devoted to the description of the cost of establishing and maintaining a rubber plantation up to the seventh year of its existence, when tapping operations commence. Figures for planta- tions in Ceylon and the Malay Peninsula are given which serve as a guide, but the author is careful to point out that expenses vary in different countries according to the cost of labour, land, and transport. The seeds of the rubber tree yield a drying oil which it is suggested will probably be heard more of in the future when the large number of. cultivated trees reach a seed-bearing age. The book is well printed and fully illustrated, and should prove of value to those desirous of obtaining practical information regarding the rubber planting industry. “Dent’s Scientific Primers.” Various authors.

This is a series of scientific primers with exceedingly clear illustra- tions, particularly in the microscopical sections in the botany and Sea Se Sa rare i an so a pipe lal | ] BOOK REVIEWS. 259 biology primers, and in the drawings of apparatus in that on chemistry. In the preface to the botany primer the author advises that the primers should be read in the following order: (1) Chemistry, (2) Biology, (83) Botany. This valuable advice to the beginner will save him great labour and disappointment. . The authors are masters of their respective subjects, and deal with them in such a way as to be understood by the veriest beginner who seeks for knowledge. That on chemistry is written by Professor Tilden, that on biology by Professor Harvey Gibson, and that on botany by Professor Reynolds Green. “Fossil Plants.” Sixty photographs illustrating the Flora of the Coal-measures. By EH. A. Newell Arber, M.A., F.Z.S., F.G.S. 18mo., 75 pp. (Gowans & Gray, London, 1909.) 6d. net. This little book consists of photographs of fossil plants from the Coal- measures, with a series of short non-technical descriptions by an eminent palaeobotanist at the end. We have spent many hours collecting speci- mens of these plants both above and underground, and we do not hesitate to say that the photographs are remarkably true and clear in ey ery detail. It is a wonderful sixpennyworth. “A First Book of Botany.’’ By Elizabeth Healey, A.R.C.Sc. Sm. 8vo., 142 pp. (Macmillan, London, 1909.) 1s. 6d. A ‘first book ”’ of botany is one requiring the art of omission. When there is such a wealth of matter, the greater is the difficulty in so choosing as to cover the ground with regard to essentials, and yet be seasonal in arrangement. We think in this case the choice is well graduated, and the specimens, with one exception, easily obtainable. The practical work suggested at the end of each chapter is excellent. Where matter and arrangement are so good, one is loth to complain ; yet we think the illustration on p. 40 is far from clear, particularly the tubers and the roots. We would like to see the illustrations of the hazel ‘and the birch, and in fact all the details of the trees mentioned, on a larger scale. It is a book we can strongly recommend to beginners in botany. “Trees and Shrubs of the British Isles, Native and Acclimatised.” By C. 8. Cooper, F.R.H.S., and W. Percival Westall, F.L.8. 4to. Parts 2-11. 214 pp.in each. (Dent, London, 1909.) Hach 1s. net. The first part of this work was reviewed when published, and now ten further parts have appeared. The greater parts of the numbers from two to seven are taken up with carefully prepared chapters on insect and fungoid pests and on insecticides and fungicides. As usual, the descriptions of the trees and shrubs are condensed and to the point, while the many beautiful illustra- tions, which have been prepared with the minutest care, cannot fail to render the book when completed a reference work of no mean order. It must not be taken for granted that all the shrubs of which 260 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. descriptions are given are hardy in every part of Great Britain, as several will only succeed in the warmest and most sheltered of seaside situations. Altogether the work is one of which we cannot speak too highly, and in recommending it to the student we feel that the concise and accurate descriptions and beautifully executed illustrations will render recognition of our trees and shrubs by no means a difficult matter. “Tondon’s Forest: Its History, Traditions and Romance.” By Percival J. S. Perceval. 8vo., 280 pp. (Dent, London, 1909.) 3s. 6d. net. This is a well got up and highly interesting account of Epping Forest, the only forest which is a heritage of the City of London. Its official connection with the Metropolis’ romantic history, both topo- graphical and historical, are stories lucidly and well told by the author, while the numerous illustrations will go far in whetting the appetite of the reader regarding this precious fragment of forest. The chapter on the ‘‘ trees and the deer—the lopping and fuel rights and history of the deer’”’ is well written, though to us who know the forest well it is always a source of regret that lopping should have been so extensively engaged in, for that it has been the direct cause of the early decay of many trees will be denied by none. However that may be, we have still left to us a forest of which we may well feel proud, whether for its historical connections or its great natural beauty. We strongly recommend those who are at all interested in forest land to carefully peruse Mr. Perceval’s remarks regarding this heritage of the citizens of London. “The Battle of Land and Sea.’ By W. Ashton. 8vo., 211 pp. (Heywood, London, 1909.) Paper boards, 1s. 6d. net. An interesting account of the origin and formation of the great line of sandhills on the Lancashire, Cheshire and North Wales Coasts, including besides much of interest in local history. “Trees and Flowers of England and Wales.”’ By H. G. Jameson. 8yo., 186 pp. (Simpkin, Marshall, London, 1909.) 2s. 6d. net. This is a “ key’ by which the name of any native flowering plant, not a grass or sedge, may be ascertained with ease. It differs from other keys in being profusely illustrated by clear, though small, sketches, illustrating the principal points of importance in separating one plant from its near allies, and the points given in the key are stated in clear and simple language so that a reader with scarcely any knowledge of plants could hardly be at a loss to understand them. Anyone desiring to ascertain the name of any British plant will find this a most useful aid. “The Nature Book.” By various authors. 4to., 752 pp. (Cassell, London, 1908-09.) In 24 parts, 7d. each net. The awakening of a more general interest in, and love of, natural surroundings, has led to the publication of a host of books, some very good, others not so good. The value of such books must be gauged, not so much by the information they supply, as by the effect they have upon 1 BOOK REVIEWS, 261 their readers. They should awaken a desire to know more, and should stimulate them to find out more for themselves from the actual natural objects. Judged by this standard, the present book will not fail, for it treats of wild plants, of trees, and birds and beasts, of fish and insects, of gardens and the weather, and of many other such things in a clear and entertaining way, so that the nature-lover may verify for himself what is stated, and in the doing he may learn more of nature’s hidden truths. The printing and general “get up’ of the book is excellent, and the illustrations, both coloured and half-tone, are deserving of praise. “Familiar Wild Flowers.” By F. E. Hulme, F.L.S. New issue. Vol. I, 8vo., pp. 168. (Cassell, London, 1909.) In parts 6d. each net. This is a reprint of a well-known popular work on British wild flowers, with (in all) 360 coloured illustrations of British wild plants and descriptive notes concerning each. Many quotations from old herbals and other old works are given. “Pruning.” Anon. 84x10, 66 pp. (Lockwood Press, London, 1909.) 1s. net. This is a revised reprint of a series of articles which first appeared in “The Fruit, Flower and Vegetable Trades’ Journal.’ It is written for commercial fruit growers and contains an appendix treating of pruning from the standpoint of the small-holder. Seldom have we seen a more excellent series of articles upon this difficult subject. The author is a practical fruit grower who has learned to make use of his eyes, to think carefully over what he has seen, and to draw accurate inferences from his observations. All sides of the subject so far as hardy fruit growing outdoors is concerned, are ably handled, and the author has good advice to give upon each. The present differs from many other books and articles dealing with pruning in that the author recognizes the fact that each variety of fruit has its own peculiar habit of growth and fruiting, and he deals with them accordingly, showing how the pruning is to be done, and why it is to be done in that particular way. This method of treatment makes the book of peculiar value to the commercial fruit grower, especially as the varieties dealt with are those that find the greatest favour in the market. The tools to be used and such things as gloves, aprons, and so on suitable for use are dealt with, and the author, very properly, decries the use of secateurs. The knife, and occasionally the long-arm pruners, are the only tools required. Secateurs are clumsy and more liable to bruise the tree than the knife, making wounds difficult or impossible to heal. The shape of the book is unusual and we think not very handy, and we hope the author will be induced to extend his work and publish it in another form, with perhaps larger illustrations. As it is, no commercial fruit grower should be without it. 262 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY CABBAGES AT WISLEY, 1908-09. Eraury-srx stocks of Cabbage were received for trial.

ONE HUNDRED AND THIRTEEN stocks of Cabbage lettuce, and forty-one stocks of Cos lettuce were received for trial, the former being sown on April 26, the latter on May 3. In almost every case the germination was excellent, the cool damp season. suiting the hot sandy soil admirably. Although the ground had only been moderately manured, the whole collection was so good that the Fruit and Vegetable Committee wished it to be recorded in the Report that it was the finest trial they had ever seen. Many stocks under different names were so much alike that it was impossible to detect any difference, consequently they are referred to the type. As the various stocks came into use they were examined by the Committee. F.C.C.=First Class Certificate. A.M.=Award of Merit. XXX= Highly Commended.

SENIORS: OVER 18 YEARS OF AGE. ONE HUNDRED AND FIFTY-ONE Senior candidates entered, of whom 19, or upwards of 12 per cent., obtained a place in the first class; 69, or upwards of 45 per cent., gained a second class; and 60, or nearly 40 per cent., are placed in the third class. Three candidates only failed to satisfy the examiners. In addition to these, four students resident in India entered for the examination, the questions set by the other examiners being specially adapted to India by the kind assistance of Lieut.-Colonel Prain, F.R.S., and of these four candidates three obtained a second class and one failed altogether. In their report to the Council the examiners (the Rev. Professor George Henslow, M.A., V.M.H., &c., and Mr. James Douglas, V.M.H.), lay stress on the fact that the answers to the questions on the ‘ Principles of Horticulture’ were very satisfactory, especially those on Physiology, which were certainly the most important, and which, they are glad to say, were generally answered. ‘The examiners also report that they were pleased to find that several of the candidates were well instructed in the somewhat new subjects of Ecology and Mendelism. It is necessary, however, to again urge the importance of candidates studying the instructions printed at the head of their paper, before beginning to answer the questions. Fourteen candidates, for example, attempted to answer all the eight questions in ‘“‘ Operations and Practice,” instead of confining themselves (as they were instructed) to four, and it is surely needless to say that four answered well are far better than eight answered poorly. In some cases, again, candidates were so prolix in their answers—had so much to say—that they only left themselves time to reply to three questions instead of to four. It is therefore necessary to urge again the importance of candidates practising conciseness in answering questions, otherwise they waste their own time and the examiners’ also. The questions on “ Practice ’’ were for the most part very well answered. JUNIORS : UNDER 18 YEARS OF AGE. Although the same questions were this year set to the Juniors as to the Seniors, an entirely different standard was looked for in their replies. One hundred and forty junior candidates entered, of whom 17, or upwards of 12 per cent., ‘have been placed in the first class ; 41, or 80 per * See also p. 92. EXAMINATIONS IN HORTICULTURE, 1909. 273 cent.,in the second ; and 60, or nearly 43 per cent.,in the third ; 22 failed altogether. With regard to “ Principles’’ the examiners report that as a rule it was only quantity and not quality that was deficient. As far as the students had learnt there were no serious mistakes, and the answers, in fact, were distinctly encouraging. In “Operations and Practice,’ again, the examiners report that, considering the age of the candidates, the answers were very satisfactory, and they specially note that many of them showed a very fair knowledge of the different kinds of manures and of their application to the different kinds of soils. The fact of 22 failures out of 140 should not discourage the students from trying again; all the examiners look for is a quite elementary knowledge of the ‘‘ Principles’’ and a fair general acquaintance with “ Operations and Practice.”’ W.

A FEw candidates gave serious trouble to the examiners not only by mixing up their papers without reference to numerical order, but also in several instances by beginning replies in Section B upon the same paper as Section A. It is most important for every candidate to read carefully the instructions printed above the questions and follow them exactly. In numerous instances candidates sacrificed time by unduly elaborating their early replies. The best work was found, as is always the case, where both clearness and conciseness were combined with evidence of practical knowledge. : The Examiners, Mr. A. Dean, V.M.H., Mr. F. J. Chittenden, F.L.S., and Mr. Jas. Hudson, V.M.H., report that in very few cases did there seem ' to be any practical knowledge of “ budding ”’ in the creation of fruit trees, grafting being almost solely in the minds of the candidates. In some instances both Fruit-trees and Raspberries were credited with being propagated from cuttings. The term “ planting’ was frequently applied to seed sowing. Considerable confusion as to what constitutes hardiness in plants prevailed. Annuals also were strangely mixed with Herbaceous Plants. Whilst the replies, generally, with regard to School-Garden plots, were satisfactory, great divergence as to their dimensions prevailed. This probably arose from the diverse sizes of these plots in various localities. Some of the candidates had evidently taken note of the latest regulations that have been issued and benefited thereby. ? The treatment of neglected gardens—a most important feature—was in some few cases treated well, and in a practical manner. The answers to the questions dealing with the Principles of Horticul- ture were, on the whole, more satisfactory than last year. The subject of manures, other than farmyard manure, is, however, one that appears to require more study, and the importance of hoeing as an aid to the reten- tion of water in soils was too often overlooked. More attention to simple illustrative experiments, simple enough to be grasped by intelligent children of school age and sufficiently to the point to illustrate the matters dealt with, would be well repaid. In the answers to the last question the deep significance of the fact that the seed is the result of the union of two entities; the consequent probability of considerable variation from the characters of the seed-bear- ing parent; the probable chances of survival in a changing environment and the possibly increased capacity of the seedlings for availing them- selves of opportunities for colonizing new situations—all these were almost entirely ignored. The difference also between the tuberous-root of the dahlia and the tuber of the potato seems to have been noticed by 7 EXAMINATIONS IN HORTICULTURE, 1909. 281 few, and yet in the garden the treatment of these two common plants is intimately connected with the differences in structure. Generally speaking, however, the knowledge evinced in the majority of papers presented to the Examiners must, when imparted to the scholars, be productive of good results to their future well-being; and it is most satisfactory to know that the possession of these Certificates of qualifica- tion to teach Cottage and Allotment Gardening is being so widely recognized by the Managers of Schools throughout the country.

JUDGING by thé number of appreciative letters received, the endeavour commenced in volume xxvi. to enlarge the usefulness of the Society’s Journal, by giving an abstract of current Horticultural periodical literature, has met with success. It has certainly entailed vastly more labour than was anticipated, and should therefore make the Fellows’ thanks to those who have helped in the work all the more hearty. There are still, we feel, some departments of Horticulture and Horticultural Science very imperfectly represented in these abstracts, and the Editor would be grateful if any who have time at command, and who are willing to help in any special direction in this work, would communicate with him. He desires to express his most grateful thanks to all who co-operate in the work, and he ventures to express the hope that they will all strictly adhere to the general order and scheme of working, as the observance of an identical order can alone enable the Editor to continue to cope with the work. The order agreed on is as follows :— 1. To place first the name of the plant, disease, pest, &c., being noticed ; and in this, the prominent governing or index word should always _ have aeedence 2. To place next the name, when given, of the author of the original article. 3. Then, the abbreviated form of the name of the journal, &c., in which the original article appears, taking care to use the abbreviation which will be found on pp. 264, 265. 4. After this, a reference to the number, date, and page of the journal in pay . If an illustration be given, to note the fact next, as “ fig.,” “ tab.,”’ ee LIST OF CONTRIBUTORS. 287 6. After these preliminary necessities for making reference to the original possible for the reader, the abstract or digest should follow, ending up with the initials of the contributor affixed at the close of each Abstract or Note.

NOTES AND AbSTRACTS Aloe ciliaris. By F. Morel (Rev. Hort., August 16, 1909, pp. 380- 881; coloured plate)—A very beautiful winter-flowering Aloe, bearing trusses of brilliant deep orange red tubular flowers, as in Kniphofia, but laxer. A rampant climbing Aloe of much beauty.—C. 7. D. Amygdalus nana. By 8S. Mottet (Le Jard. xxiii. 527, p. 69; March 5, 1909; 1 fig.).—A too-neglected type of flowering almond. A distinct species from the South of Russia, whence it was imported in 1783. A. nana is only 1 metre high. It has deep pink flowers, and is very useful for cutting. Other species are alba, argentea, fruticosa, Gesleriana, georgica (one of the most distinct), microcarpa, serrata, &c. All these are quite hardy and are most useful as foreground shrubs, for rock work, and in forcing for cut flowers.—/’. A. W. Anthocyane. By R. Combes (Ann. Sc. Nat. vol. ix. Nos. 4-5, pp. 274-303).—Anthocyane, the pigment present in the autumnal tinted leaves of Ampelopsis hederacea, Rosa canina, Berberis Aquifolium, &e., is a glucoside. ‘The red leaves are richer in sugars and glucosides, but poorer in dextrine than the green leaves of the same plant. The pigment is only formed in the presence of oxygen. The rate of respiration of plants is increased by the presence of sugar, hence the accumulation of sugar in the leaves favours the formation of the pigment.—S. H. W. Aphides, Orehard. By C. P. Gillette (Jour. Hcon. Hmtom. i. (1908) 5. p. 802; and 6. p. 859).—Technical descriptions of aphides attacking orchard trees are given together with figures. The insects dealt with are the green apple aphis (Aphis pomi de Geer=A. mali Buckton) ; the woolly apple aphis (Schizonewra lanigera Hausm): the black peach aphis (Aphis persicae-niger Smith); the green peach aphis (Myzus persicae Sulz.) a great pest with a very wide range of food plants; the black cherry (Myzus cerasi Fab.) ; and Aphis bakert Cowen, which has its winter eggs and spring forms on the apple and pear and later migrates to the clover. tired ee Apple Blotch. By W. M. Scott and J. B. Rorer (U.S.A. Dep. Agr., Bur. Pl. Ind., Bull. 144; March 1909; 6 plates)—A widely distributed disease of apple, called blotch, does great damage in the Southern States, often rendering 50 per cent. of the fruit unfit for marketing. It is due to the fungus Phyllosticta solitaria. The fruits, leaves and twigs are all attacked, and the attack upon the twigs, which are caused to become cankered, plays an important part in the life cycle of the fungus. The blotch on the fruit is very small, inconspicuous and light brown at first, but it spreads rapidly, increases in size up to 2 in. in diameter, and becomes darker in colour. The margin of the blotch is irregular and jagged and has a fringed appearance. When young apples are attacked, NOTES AND ABSTRACTS. 291 since only the outer cells are killed, the fruit may crack owing to the continued growth of the uninjured tissues. The appearance of the blotches varies somewhat on different varieties of apple. The black fruits (pycnidia) of the fungus appear on the spots after a few days. The spots on the leaves are very small and of minor importance. The fungus passes the winter on the twigs, on which it forms small canker spots (which are fully described in the paper), occasionally killing the twigs. From the twig cankers the disease spreads by means of spores to the other parts of the tree, and these form the chief source of infection. Like most diseases, this is more or less dependent upon weather conditions, damp weather favouring the spread of the disease very greatly. Different varieties show very variable degrees of susceptibility to the attacks of the fungus. A description of the fungus and its cultural characters is given, and an account of spraying experiments with Bordeaux mixture, the application of which at intervals of about three weeks, commencing when the cluster buds are well out and continuing until the end of July or even later, gave satisfactory results.—f’. J. C. Apple, Croatian. By V. Nemeanis (Le Jard. xxiii. 528, p. 55; February 20, 1909; 1 fig.).—This apple is known in Croatia as Sistschika (Heart Apple). Stem smooth and rather greasy. The fruit is very large and rounded and somewhat flattened; olive-green flushed with carmine. Flesh is greenish-white, tender, juicy, slightly acid. Useful November to June, of vigorous growth and hardy, a fine orchard tree. The fruit keeps well, and is equally good for dessert and for cooking.—f’. A. W. Apples, Dimples in. By E. P. Taylor (Jour. Hoon. Entom. i. (1908) p. 370 ; figs.).—The author has found that the tarnished plant bug (Lygus pratensis L.) lay their eggs, which are of an oval, elongate, botile- shaped form, in the small slits in the apple skin while the fruits are very small. The eggs are placed singly in the incisions. A few of the apples attacked dropped early, the others developed pits in their contour as they grew larger. The dimples appear not to impair the keeping qualities of the apple.—F’. J. C. Apple-leaf Hopper. By F. L. Washburn (Jour. Econ. Entom. ii. (1909) 1. p. 54; 1 plate).—The eggs of this insect (Hmpoasca mali Le B.) are laid in small blisters on the apple and perhaps on the elm. ‘They are hyaline and semi-opaque, about as long as, but much narrower than, the blisters in which they lie. They are laid about the end of September and the insect winters in this stage. Other broods are produced in the summer and the eggs are laid on a variety of herbaceous plants. The plants on which the insects have been found are apple, clover, plum, maple, bur-oak, black oak, thorn apple, basswood, hazel, box elder, choke- berry, sumac, birch, Syringa, Carragana, raspberry, blackberry, beans, corn, lucerne, sugar beet, buckwheat, dahlia, hemp, rhubarb, potatos and grasses. The most serious damage is done to nursery stock, the curling of the leaves of the young trees causing a check in their development. Catching the insects on a tarred board as with turnip flea beetles is recommended. Professor J. B. Smith states that these insects are readily attracted by light.—-F. J. C. 292 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. Apple Orchards: Does it pay to spray? By R. A. Emerson and F. K. Denny (U.S.A. Agr. Hap. Sta., Nebraska, Bull. 106, May 1908).—A sevies of experiments was made in the Nebraska apple orchards with spraying. These proved that on the average a considerable gain accrued, after cost of spraying was deducted, not only in quality but also in quantity of first-size fruits. Full descriptions of the methods adopted are given.—Hi. F’. A. Apple Sawflies. By R. L. Webster (Jour. Hcon. Entom. vol. i. 5, p. 810; October 1908).—Certain sawfly larve feed in apples although usually feeding on other plants. Taxonus nigrisoma is reported as burrowing in apple flesh, the burrow being about half the depth from the skin to the core. This larva usually feeds on dock and Polygonum. JESSE AG. Apple-tree Tent Caterpillar. By A. L. Quaintance (U.S.A. Dep. Agr., Bur. Entom., Cire. 98; January 1908; 4 figs.).—The caterpillars of this insect (Malacosoma americana) make tents similar to those of the lackeymoth. They feed on the foliage and often cause complete defoliation. The eggs are laid in belts encircling the branches in early midsummer, and are hatched out in the spring. The larve spin cocoons in sheltered places, as under loose bark, and the perfect insect emerges about three weeks after pupation begins. A considerable number of insects are known as parasites of this, troublesome pest, and a few birds feed upon them. It is recommended that useless trees be removed, that the eggs be collected during the winter when the operation of pruning is performed, or the nests may be completely removed or burnt with a torch when the larve are at home.—F’. J. C. Apple trees injured by Tree Crickets. By P. J. Parrott (Jour. Hcon. Hntom. ii. (1909), 2, p. 124)—Spots on apple bark of a rather dark reddish brown colour with a purplish tinge, more or less circular in outline, somewhat resembling canker spots, are described as being caused by punctures of egg-laying tree crickets (Oecanthus niveus de Geer), the eggs being deposited in the punctures. ‘Trees in negleeted situations are the most commonly attacked. A comparison between the eges of Oe. niveus and Oe. nigricornis is made.—F’. J. C. Apple Trees: Spraying and Orchard Pests in Kentucky. By H. Garman (U.S.A. Agr. Hap. Sta., Kentucky, Bull. 188, January 1908 ; 27 plates)—The numerous insect and fungoid pests prevalent in the Kentucky orchards are well illustrated and described. A series of ten experiments was carried out in spraying to ascertain whether treatment | with various insecticides before or after blooming is the best. The results are set forth, but do not show any conclusive differences.—H. F’. H. Apple Trees, Tumours on. By J. Jaeger (Zeit. f. Pflanzkr. vol. xvili. No. 5, 1908, p. 257; 1 text fig..—Tumours or excrescences on the branches of young apple trees are described which cause serious damage. The outgrowths are produced by a proliferation chiefly of the tissues of the medullary rays. Whether the cause lies in abnormal conditions of nutrition or perhaps in animal pests (Tetranychus) is not yet clear. Gi die NOTES AND ABSTRACTS. 293 Araliaceae. By R. Viguier (Ann. Sc. Nat. vol. ix. No. 6, pp. 805- 405; 18 figs.)—A description of the classification, geographical dis- tribution, and morphology of Aralia, Acanthopanax, Schefiera, and Dizygotheca.—S. HE. W. Arctostaphylos nevadensis (Die Gart., p. 326; July 10, 1909).—A very hardy evergreen shrub of creeping habit with small ovate leaves, urceolate pink flowers, and orange berries. It resembles Arctostaphylos Uva-Ursi, a British plant, but is easily distinguished by the reddish bark, light green leaves, pink flowers, and bright coloured fruit.—G. R. Arsenical Sprays, Danger of, to Fruit Trees. By E. D. Ball. (Jour. Econ. Entom. ii. (1909), p. 142).—The author criticises the state- ments made in a recently published bulletin of the Colorado Experiment Station (No. 118), in which the death of large numbers of apple trees had been attributed to the use of arsenical sprays. He considers the evidence not convincing, and attributes the death of the trees to other and well- known diseases, which occur in places where arsenical sprays are never used. He corroborates the bulletin so far as to warn fruit-growers against using even slightly alkaline water or water containing common salt in solution in diluting arsenical washes, and suggests that heavy spraying on alkaline soils may constitute an important source of danger.—F’. J. C. Artemisia lactiflora (Die Gart., p. 280; May 15, 1909).—A fine hardy perennial and perhaps the best of the genus. It grows from 5 to 6 feet in height, and has pinnate leaves and long panicles of small creamy white flowers which have a faint fragrance. The time of flowering is during August and September till the end of October. A very ornamental plant for beds and borders as well as the wild garden, and very useful as a cut flower.—G. fi. Asparagus Beetles. By F. H. Chittenden (U.S.A. Dep. Agr., Bur. of Entom. Circ. 102; May 1908; figs.)—life histories of these well- known European beetles (Crioceris asparagi and C. duodecimpunctata) are detailed, the larve of one living on the shoots, of the other, at least for a time, in the berries. Spraying with a wash of 1 lb. arsenate of lead, 21 lb. resin soap, and twenty-four gallons water gave excellent results. The larve of the former may be beaten off on a hot day and will perish before they reach the plants again.— fF’. J. C. Aspidiotus destructor (Sig.) and its Chaleid Parasite in Tahiti. By R. W. Doane (Jour. Hoon. Entom. i. (1908) 6. p. 341).— This scale insect is extremely injurious to cocoanuts and other palms in many parts of the tropics. The trees are often so badly infested that they are rendered unfruitful ; all parts of the tree except the roots are attacked. Recently, however, many of the trees in Tahiti have shown signs of recovery and the author has ascertained that this is due to the destruction of the scale insects by the chalcid parasite Aspidiotiphagus citrinus Craw. On some trees from 50 per cent. to 70 per cent. of the scale insects were found to be parasitized. The parasite was also found on some of the neighbouring islands.—F’. J. C. 294 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY, Basket Willows, Production and Consumption of, in the United States for 1906 and 1907. By C. D. Ekell (U.S.A. Depi. Agr., Forest Service, Circ. 150; January 1909).—To those who are interested in the culture of willows for basket-making this pamphlet will be instructive. As with us the varieties of willows grown are numerous, many being of local growth and named accordingly. The annual con- sumption of home-grown peeled basket willows in the United States at present approximates 855 tons, the cost of unpeeled wands being from £12 to £20 the ton—the peeled of course commanding a much higher price. The old English industries of willow-growing and basket-making are almost things of the past, cheap foreign productions and preferential carriage rates having well-nigh ousted this woodland occupation of our forefathers. It will be interesting to note how the industry succeeds in America.—A. D. W. Begonia, Abnormal Flowers of. By Prof. F. Hildebrand (Bezh. Bot. Centralbl. vol. xxv. Abth. 1, Heft 1, pp. 81-114, August 1909; 2 figs. and 8 plates).—Describes very fully some peculiar sports and abnormalities in certain flowers of Begonia.—G. FF. S.-H. Bordeaux Mixture, Effect on Potato-leaf Assimilation. By QO. Kirchner (Zeit. f. Pflanzkr. vol. xviii. No. 2, 1908, p. 65).—Apart from its action in warding off Phytophthora, Bordeaux mixture has been credited with the power of increasing the assimilatory power of the potato foliage and thus increasing the yield. Some have explained this by assuming that the copper salt exercises a tonic or stimulating effect on starch formation. Others have explained it as being the result of the shading of the leaf caused by the film of sprayed material on it which they consider acts beneficially, although still other observers consider that this shading action is the reverse of beneficial. Kirchner’s object is to ascertain whether it really is a fact that spray- ing potatos with Bordeaux mixture does—in the absence of potato blight —really cause an increased yield. He first reviews critically the field results of previous investigators, placing them in three groups. (1) Six cases where sprayed potatos (in the absence of Phytophthora) gave a smaller yield than the unsprayed. (2) Four cases where the sprayed plants pro- duced wholly or partly a greater yield than the unsprayed, the increase being explained as due not to increased energy of leaf assimilation but purely to the increased duration of life of the sprayed foliage. (8) Five cases in which the sprayed plants gave a greater yield than the unsprayed without any explanation being given as to the reason why. He then gives a detailed account of his own experiments. In 1904 there was practically no difference in yield between sprayed and unsprayed. In 1905 there was a difference in favour of the sprayed which is partly explained by the increased leneth of life of the foliage. In 1906 no results could be obtained as Phytophthora was very abundant. In 1907 there was a very decided decrease in yield in the sprayed plants, which could not be entirely put down to shading and which suggests the idea of a direct poisonous action on the plant of the Bordeaux mixture. ~ Gis NOTES AND ABSTRACTS, 2.95 Bordeaux Mixture, Points in the Preparation of. By W. Kelhofer (Internat. phytopath. Dienst. vol. i. No. 3, 1908, p. 65).—The character and action of Bordeaux mixture depend on the quality of the materials, the quantities of each used, and the method of preparation. The greater the amount of lime used, the sooner the precipitate loses its flocculent nature and the more easily it is washed off the foliage, but if only the amount of lime theoretically required is used there is a danger of the copper soon becoming soluble and washing off. Hence to prevent mechanical washing off and to retard the solution of the film of copper salt, it is best not to use the mixture in a neutral condition, but to use excess of lime, the amount depending on the kind, intensity, and frequency of the prevalent rains in a given district. The solution should be mixed cold, and the copper sulphate and the lime should each be diluted as far as possible before mixing, i.e. the copper sulphate should be dissolved in half the total quantity of water that is to be used and the lime mixed with the other half. The copper sulphate solution should be poured into the milk of lime slowly, and not vice versd. The mixture is almost as good if the milk of lime is poured quwickly into the copper sulphate solution, but it is difficult to do this, and the former method works best in practice. Certain additions are advantageous—in particular, sugar. In France, sugar in large quantity was formerly much used, but Kelhofer finds that a very small quantity is all that is necessary, the actual amount depending on the quantity of lime used. In practice with the usual 2 per cent. formula, 50 grams of sugar to each 2 hectolitres is suitable. The sugar acts asa preservative (it must be added at the time of mixing, or at least within twenty-four hours of this), and when it is used, the whole amount of mixture required for one season may be prepared at one time and used when required.—G.

The author states that bracken contains three times aS much nitrogen, and as much phosphoric acid as straw, but less potash. Its manurial value is about 50 per cent. higher than that of straw. It possesses greater absorbing power than straw, but is much inferior to peat moss. As a manure its decomposition is slow, which renders it more effective on heavy clay soil.—H. B. Cabbage Bug, The Harlequin. By F. H. Chittenden (U.S.A. Dep.

The adult insect is red and black and quite conspicuous. It is native in Mexico and Central America, and is spreading northward, where it is likely to do great damage until adverse climatic conditions check its progress. It is recom- mended to plant early crops of rape, radish, or mustard that would attract the insects, and then to destroy these by means of hand torches, etc. JG dio Op 296 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. Carnations, Effect of Gas upon. By W. Crocker and Lee J. Knight (Bot. Gaz. vol. xlvi. pp. 259-276, October 1908; 4 figs.).—A series of experiments has been made illustrating the fatal effect of coal-gas upon carnations. Young buds of ‘ Boston Market’ and ‘Pink Lawson’ may be killed by three days’ exposure to an atmosphere containing only one part of coal-gas to 40,000 of pure air. Open flowers of these varieties close after twelve hours’ exposure to one part in 80,000. Ethylene is still more dangerous, for one part in a million prevents the opening of buds (three days’ exposure), and one part in 2,000,000 causes the closing of flowers already open. The ethylene in coal-gas may determine the “ toxic limit” in the case of these flowers. Go. Ef Cascara Sagrada (Gard. Mag.

Dublesel (Le Jard. xxii. 523, p. 866, December 5, 1908; 1 fig.).—Chicory is extraordinarily subject to caterpillar plagues, and Hadena oleracea seems to be on the increase. The caterpillar is green or grey brown, with white dots, while each segment bears warty spots. On the upper surface of the body there © are three longitudinal white lines, with a lateral yellow line at the origin of the feet. The chrysalis is rusty brown. The moth, which comes out from May onwards, is reddish-brown above, with lighter colour in the median half. An M-shaped white line extends along the outer border. Spraying with soap water is the usual remedy, but seems to destroy only the smallest caterpillars. Otherwise they may be shaken off, and then crushed on the ground.—F’. A. W. Chlorophyll. By J. d’Arbamount (Ann. Sc. Nat. vol. ix. Nos. 4-5, pp. 19%—229.)—Chlorophyll bodies may be divided into chloroplasts NOTES AND ABSTRACTS. 297 and pseudochloroplasts. The former have a spongy, filamentous or reticulated structure and are not as a rule stained by an acid solution of aniline blue. The pseudochloroplasts are subdivided into four varieties. They exist in the form of spangles or conglomerations of spangles and are stained by aniline blue. It is the pseudochloroplasts which fulfil the important function of reducing the carbonic acid of the atmosphere. Many of our large forest trees contain only pseudo- chloroplasts. In certain members of the vegetable kingdom, starch is essential for the formation of both classes of chlorophyll; in other plants starch is not necessary for its production, e.g. in the bud of the sycamore. In some buds the appearance of starch granules precedes the formation of chlorophyll, in others the case is reversed.—S. H. W. Chrysanthemum Sports, How to induce them. By G. T. Grignan (fev. Hort., May 1, 1909, p. 196).—It is suggested that variation is induced by excessive propagation; cuttings are taken repeatedly as soon as they are long enough, and it is the later cuttings which are assumed to be less robust and to lose to some extent their equilibrium, the result being, especially if the major part of the plant be removed, a greater tendency to produce sports. Under such conditions the writer cites the production of ‘Madame Constant Walker,’ while ‘Mrs. Henry Robinson’ gives each year yellow sports. ‘Souvenir de Madame Maniére’ also produced a yellow sport the first year it was put on the market. Cultivators on a large scale have thus a greater chance proportionally than small ones.—C. T’.. D. Ciders and Perries, The Rate of Fermentation of. By B. T. P. Barker, M.A. (Jour. Agr. Scz. iii. (1908) 1, p. 1).—The author finds that the rate of fermentation of different ciders and perries varies markedly, and considers it probable that some varieties of fruit yield juices which ferment more rapidly than others. The main factor in determining the rate of fermentation appears to be the nitrogenous matter present in the juice, which is assimilable by the yeast, and the quantity present is usually below the optimum quantity for rapid fermen- tation. If other substances influence the rate of fermentation their influence is masked by this more important substance. The state of ripeness at the time of milling affects the rate of fermentation, the latter being at its slowest when the period of perfect ripeness is reached, and increasing as ripeness proceeds to decay. The rate of fermentation is also decreased when the fruit has been exposed to bright sunshine. In practical cider-making the rate of fermentation does not appear to be influenced by the high or low fermentative powers of the yeasts present, the varieties normally present being capable of maintaining the fermentation at the maximum rate allowed by the nitrogenous constitution of the juice. | The admission of air to the juice has a marked effect in increasing the rate of fermentation, which is also influenced in the usual way by changes in temperature. The author points out that it should be possible to exercise some amount of control over the rate of fermentation by judiciously blending VOL.

All that is necessary is to use a fine mist-like spray which will leave a small amount of deposit within the cup. In vol. 2. p. 67, Mr. Melander returns to the subject and gives reasons why great force should be used in applying the arsenical washes. EJS. G. Copper Carbonates and the Cupri-Carbonates. By Spencer U. Pickering, F.R.S. (Jowr. Chem. Soc., vol. xcv.; August 1909; pp. 1409- 1429 ; table)—An investigation into the constitution of the carbonates of copper and allied compounds. The author prefaces his paper with a useful compilation of the known ~ facts as to the compounds of copper and carbonic acid known or believed to be produced under various conditions. This paper is of especial interest to horticulturists in view of the important part copper salts play as fungicides. The author found precipitation of copper sulphate in the cold with normal sodium carbonate to produce invariably a basic carbonate 10Cu04CO,. This salt is therefore largely the basis of a preparation fre- quently recommended and used for potato-spraying. The salt decomposes on boiling, evolving CO,, until finally only traces of carbonate remain. NOTES AND ABSTRACTS. 299 When sodium bi-carbonate is added to weak solutions of copper sulphate, the basic carbonate 5CuO8CO, is produced, the precipitate being contaminated with sodium carbonate and basic sulphate, especially when excess of copper is present. When concentrated solutions are used CO, is evolved, and the precipitate formed redissolves. _ Perhaps the most interesting part of the investigation is that of the cupri-carbonates, a name given by the author to the hitherto uninvesti- gated compounds produced by the solution of certain of the basic carbonates in sodium carbonate. These were produced by reacting with mixed solutions of carbonate and bi-carbonate of soda upon copper sulphate, and in these the copper becomes electro-negative, taking its place as a constituent of the acid radicle; in this state it does not respond to the usual tests for copper, such as potassium ferrocyanide (prussiate of potash). The normal carbonate of copper has not yet been isolated. W. A. V. Crambe cordifolia. By S. Mottet (Le Jard. xxiii. 527, p. 37; February 5, 1909; 1 fig.)—The genus Crambe is little known as an ornamental plant; C. maritima (the seakale) is a favourite vegetable ; C. tatarica is also edible, but is less inviting; C. jwncea, and lastly C. cordifolia. This handsome plant is native in the Caucasus and Siberia ; hence it is perfectly hardy, and might well be planted out in parks and shrubberies. The leaves are shiny and dark green, about 18 inches across. ‘The flowers are white and sweet-scented, very small, but arranged in long heads or sprays like Spiraea Aruncus. These plumes are easily blown down and broken, so it is well to tie them to a stake as soon as developed. ‘The plant prefers a sunny aspect, and will flower ten years or more without degenerating. It may be divided in spring.—F’. A. W. Crataegus, New Species of. By F. Ramaley (Bot. Gaz. vol. xlvi. pp. 881-384 ; November 1908; 2 figs.)—Two new species are described from Colorado, viz. C.

Houssy (Le Jard. xxiii. 525, p. 10; January 5, 1909).—Watercress is so easily cultivated, and so lucrative, seeing that it only requires a ditch some 50-60 cm. deep, and 50-60 metres long, that it is a pity more use is not made of it for the English market. Clay soil is the best, as a moderate flow of water from sume neighbouring spring will then provide sufficient to moisten the trenches ; in light or sandy soil it is necessary to line the ditches, which adds to the cost of production. A cress ditch can be reaped every three months ; the plants are best renewed every year. Another methcd is to saw a barrel in half, and fill the tubs with water, covered with a trellis of wicker or galvanized iron. Plant cress on the top of the meshes. It is not necessary to change the water, as it remains good from May to November. Fertilize with ammonium sulphate every three weeks. This should be pulverized and spread on the water, or dissolved in water and poured in. Again, the tubs may be cut down to 50 cm. from the ground and filled with earth, leaving a drain pipe in the centre, down which water is poured daily. Another plan is to pave a bed of soil with the inverted bottoms x2 a a St IT TI 300 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. of bottles. The depression at the bottom catches and holds water, and if cress is planted between the bottles and watered daily it thrives well. If attacked by small green caterpillars, a spray of nicotine 1 in 10 will remove them.—/’. A. W. Cucumber Beetle, The Striped. By F. H. Chittenden (U.S.A. Dep. Agr., Dw.

The area of H. rhamnoides extends from W. Europe to W. China and from 67° N. lat. to the Mediterranean. It does not occur on the Atlas. It is found from sea level to 2,000 metres alt. in mid Europe and up to 4,000 m. in the Himalayas. It grows best on an argillaceo- siliceous soil which is permeable to water. The place must be sunny and not covered by turf. A particularly favourable situation is the bare slope of a ravine. The author doubts Koppen’s view that it existed on the shores of all the tertiary seas, and hence reached the Alps, Caucasus and Himalayas during the period of upheaval of these mountains. The fossils Holliculite and Carpolithes are supposed by him to be seeds of Stratiotes, and other leaves ascribed to Hippophae are very like Pimelea or Cornus. Several new species of Hleagnus are described (by the subdivision of H. latifolia and from new discoveries). The distribution is interesting, for each group of allied species belongs to a definite geographical area, although the respective areas of two different groups may overlap. The author admits H. arcticus, Heer, from the miocene of Greenland as a true Hleagnus. The seeds may be distributed by NOTES AND ABSTRACTS. 801 ocean currents.

The preliminary chapters are devoted to the geography, geology, meteorology, and bibliography of the district. Then follows the list of species, with habitats, altitudes, and other notes (mosses and ferns included). After the flora follows a description in great detail of the various vegetation types, such as the woodland floras. These types are divided into “formation groups’’ as deciduous and coniferous woods. Hach group is then considered in detail (Oakwood, Chestnut, and Beech formations). Every formation is then divided into special groups, such as in the case of the Oakwood formation—(a) Highwood, (b) Bushwood, and (c) Submediterranean Bushwood. Lists of dominant and other species are given under each of these headings. This treatment involves of course a very thorough description of the usual types of associations. There are sixteen types of grass floras alone without including the mixed and subtypes. The last chapter is headed ‘“‘The Regions,” an gives the altitudinal limits of the Submontane, Montane, Subalpine, and Alpine regions, as well as of the Mediterranean extensions which occur up to about 400 m.

Forcing: Hot-Water v. Etherization. By Professor Hans Molisch, translated by E. Lemoine (Le Jard., vol. xxii. p. 865, No. 523; December 5, 1908).—Eight years ago Professor Johannsen demonstrated that lilacs and other plants in a resting state could be awakened to growth at the beginning of the autumn, if subjected for twenty-four or forty-eight hours to the action of ether, and then forced in the usual way. AD a eg er 302 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. This method now seems likely to be supplanted by that of hot-water forcing. In 1906 M. Ferd. Molisch, of Brunn, tried plunging lilacs in November into water at a temperature of 80°-36° C., maintained at con- stant temperature for ten to fifteen hours, after which they were forced in the usual way. In Russia the same method was applied to lilies of the valley. The crowns to be forced were soaked for twelve or sixteen hours in water at 35° C.; they were then forced at 380°-82°5° C., and flowered several days before the control plants. Seeing these practical effects Professor Hans Molisch made a scien- tific study of the method, which is summarized as follows : 1. If shoots or rooted shrubs are plunged into water at 30° or 40° C. during their resting period (only the aérial part of rooted plants being plunged), and soaked for several hours, and subsequently grown on in moderate heat, the resting time will, in many cases, be shortened, and the buds will develop more quickly, ‘The process succeeds well with the following: Corylus Avellana, Syringa vulgaris, Forsythia suspensa, Cornus alba, Ribes Grossularia, Larix decidua, Khamnus Frangula, Aesculus Hippocastanum, Salix, Fraxinus excelsior, &e. Besides the kind of plant and season of the year, success depends on the following factors :— a. Length of bath. Six to twelve hours is usually enough. It is well not to exceed twelve hours, because oxidation is very active at this high temperature, and as the O content of water is very limited, the respiration of the plants is hampered, and the buds are damaged or destroyed. b. The temperature must vary for different plants, and must be found by experiment. Corylus, Forsythia, Ribes, Syringa are started by a bath of 80° C., while Cornus, Rhamnus, and Betula alba require 35° to 40° C. . c. The action of the bath depends upon the stage of rest that the plants arein. In some it takes effect directly the leaves have fallen, in others much later on. If boughs of ash and horse- chestnut are soaked early in the autumn, they will not force ; soaked in December and January, they come on well. 2. The action is purely local. This can be seen by plunging only half the shrub, when the result is unmistakable. A lilac soaked on one side only in November, and then forced, will soon be covered with bloom on the one side, while the other retains its winter appearance. 3. The effect of the hot bath persists even when the plants thus treated are put out in the ground for the rest of the autumn or winter. — Directly they are taken up and forced, they react like the plants forced directly after the bath. | 4. A prolonged bath of damp air at high temperature has the same effect on many plants as a warm bath at even temperature. In some cases it is even more successful, showing it to be the great heat that in the first instance sets up the changes. Up to the date of this article, however, the moist air bath had only been tried at the end of the autumn, when the resting state is less profound than earlier in the season—so that further experiments must be made. It also remains to discover how the heat- NOTES AND ABSTRACTS. 303 factor acts as an excitant. The internal revolution which abridges or suppresses the resting state may be due to acceleration of respiration by the great heat, but this has yet to be determined.—/’. A. W.

Hi. H. Fruits, Chemical Manures in the Intensive Culture of (La Pomologie Francaise, pp. 854-857; October-November, 1908).—The general theory of manures is: (1) that nitrogenous manures cause foliage to be formed in large quantity, they retard the ripening of tissue and lessen their resistance to frost and canker, and spoil the fertility of the trees ; (2) that phosphatic manures predispose the plants to fertility and balance vigour with the nitrogenous manures ; (8) that potassic manures aid the formation of tissue and framework: (4) that calcareous manures insure the quality and hardness of the wood, its resistance to canker, especially in apples. Soils rich in lime are stated to give fruit of better colour and quality than soil deficient in lime. Nitrogenous manures, though little affecting fruits eaten fresh, tend to make fruits required to be kept long more liable to decay. Phosphatic manures are desirable for young trees and those not fertile, nitrogenous manures for older plants lacking vigour. Stone fruits specially require lime, more so than pip fruits.

Agr., Bur. of Chem., Bull. 118; May 1908).—The vegetation was injured by a distance of from eight to twenty miles around a smelter owing to the fumes of sulphur dioxide evolved ; arsenic was also discharged from the smelter and was found in forage crops in sufficient quantities to poison cattle. Copper contained in the water of a river flowing by the smelter also greatly injured vegetation. Junipers proved more resistant to the fumes than most trees.—F’. J. C. Geotropy. By W. Grottian (Beth. Bot. Centralbl. vol. xxiv. Abth. 1, Heft 3, pp. 255-285; April 1909). The author found that very low per- centages of anesthetics (‘5 per cent. to ‘01 per cent. ether) stimulates growth and sensitiveness. Increased sensitiveness to geotropy resulted from rather higher percentages, 8 per cent. amyl alcohol and ethyl alcohol, 15 per cent. ether, and 20 per cent. chloroform. With still higher percentages all sensitiveness ceased although a feeble growth was maintained. The experiments were conducted on lupine seedlings in an atmosphere saturated with the respective vapours. The author repeated, but could find no confirmation of Czapek’s results with antiferment reactions on stimulated and unstimulated roots.—G. F’. S.-H. Gerbera Jamesoni Hybrids. By R. Adnet (Rev. Hort., May 16, 1909, pp. 230-233; coloured plate and figs.)—An interesting article on cultivation and new acquisitions. The plate represents several very fine forms, unnamed, bright yellow with pink under side, salmon, red and purple, obtained by hybridization (G. Jameson x G. iridifolia). Require very sunny positions, rich light soil, and good drainage. The hybrids are much hardier than G. Jameson, and more resistant against wet seasonal conditions, which are fatal to that species.—C. T. D. Germination and Light. By E. Heinricher (Bot. Zeit. vol. Ixvii. Abth. 1, Heft 4, pp. 45-66).—The author’s experiments with seeds of Phacelia tanacetifolia show that germination is possible in light, although a much larger percentage of the seeds germinate in darkness, In the dark 46 per cent. germinated, in blue light 39 per cent., in ordinary light 18 per cent., and in red light 8 per cent. By transferring the cultures from light to darkness, or from the red glass to the blue, a further number could be induced to germinate. Seeds germinated in the same year (two months after ripening) in darkness, but not in light. These results point to some photo-chemical effect of certain rays of light. 306 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. When the cultures were dried, and then again wetted, a greater number of seeds germinated.—G. F’.. S.-H. Germination of Orobanchaceae. By 8S. Kusano (Beth. Bot. Centralbl. vol. xxiv. Abth. 1, Heft 8, pp. 286-800 ; April 1909 ; 2 plates).— Professor S. Kusano describes (in English) the seedling of Aeginetia indica and its method of attacking the host plant. The minute few-celled embryo has at the radicular end about 15 globular epidermal cells. One or more of these cells grow out into hairs which search for the root of a host plant. Many such hairs develop if no contact is at first effected. But on touching such a root, the hairs appear to grow in between its cells; they then contract, curving in like a tendril, and so bring the little embryo into contact with the root. The embryo then grows rapidly, becoming visible to the eye, and forms a primary absorbing tissue or haustorium which penetrates the host plants and develops tracheids in connection with the conducting system of the latter. The roots of many plants appear to excrete some kind of stimulating substance which is necessary for the germination of the Aeginetia seeds, but further development only occurs near the roots of its regular host plants. Seeds wrapped in filter paper and placed near such roots germinated, but if covered by several layers of paper fewer were able to do so. So it seems probable that a definite stimulating substance is excreted by the roots. The host plants were grown in pots and the seeds placed on the inside of the pots in the meshwork formed by the roots.—G. fF’. S.-H. Gooseberry Mildew, American, in Germany. By R. Schander (Internat. phytopath. Dienst. vol. i. No 4, 1908, p. 97; 8 maps in text).— Deals with the distribution of this pest in Germany up to the year 1907. Spraying with a 1 per cent. solution of potassium sulphide retards the development of the fungus, but it cannot be regarded as a satisfactory method of control. Cutting off the twigs on which the perithecia are found in winter and those affected with mildew in summer is stated to be the best means of prevention. In one or two cases sickness is said to have been caused by the eating of affected berries, both by adults and by children (in one case a child aged 14 year died), but in a number of other cases no ill effects followed after eating affected berries. About forty cases were noticed in which the red currant was affected by the same fungus, and it also occurred on Ribes alpinum and RB. awrewm and was artificially inoculated on Ff. atropurpurewm. The author considers it advisable in districts where the disease makes its appearance for the first time and to a slight extent to completely destroy the affected bushes, but in districts where the disease has already got a firm footing this is not to be recommended; here the above-mentioned methods of cutting off and thoroughly destroying the affected twigs should be resorted to. ‘he American Mountain Gooseberry, a derivative of Rf. Cynosbati, appears to be immune, but unfortunately it bears only small fruit. Ii is suggested that attempts should be made to produce a disease- resistant variety. [Eriksson has found (1909) that in Sweden, at any rate, the American Mountain Gooseberry is not actually immune but only less susceptible to the disease].—G. H. P. NOTES AND ABSTRACTS, 307 Gooseberry Mildew, American. Occurrence in Japan. ByE.S. Salmon (Internat. phytopath. Dienst. vol.i. No. 2, 1908, p. 59).—The fungus causing this disease, or at any rate a variety of it, was observed on Stephanandra flexuosa from Japan. It is morphologically almost identical with that attacking species of Azbes in these islands, although the perithecia and asci of the Japanese form are slightly smaller than those of the American species. It is not yet known whether it occurs in Japanon any species of Fibes. It has been recorded as Sphaerotheca mors-uvae var. gaponica.—G. H. P. Grape-vine Root-borer, The. By F. HE. Brooks (U.S.A. Hzp. Sin., Virginia, Bull. 110 ; November 1907 ; figs.)—The larve of the moth Memythrus polistiformis feed in the roots of vines in many parts of the States, at times doing considerable damage. A description of the moth and its larva is given, and full notes upon its life history. The pest is difficult to combat, since the larva feeds in the root, a foot or more from the stem of the plant. Digging out the larvae is almost impracticable ; profitable immune varieties are not known; the moths may be killed in August, and it is considered that thorough cultivation will greatly reduce the ravages of the pest.— Ff’. J. C. Grass of the Alpine region in Colorado. By T. Holm (Bot. Gaz. vol. xlvi. pp. 422-454; December 1908; 5 figs. and 1 plate).—The author has examined the distribution of the specially alpine grasses both in the Colorado Rockies and throughout the North Temperate Hemisphere. Of special interest to British readers are his tables illustrating the range of Phleum alpinum, Aira caespitosa, Poa alpina and Festuca ovina. These Alpine species are more cosmopolitan than those found at lower altitudes, and some arctic and circumpolar species are characteristic of alpine floras. He found also that the habit as well as the floral and anatomical characters of the alpine species are very uniform and simple. | G. F. S.-H. Greenhouse Crops, Soil Treatment for. By H. J. Wheeler and G. H. Adams (U.S.A. Exp. Sin, R.I., Bull. 128; June 1908).— Experiments were carried out to ascertain whether manuring with farm- yard manure or with chemical fertilizers gave the best results in the cultivation of certain plants under glass. Radishes and lettuces, especially . the former, were found to mature earlier and to yield heavier, but different varieties of carnations varied greatly.—F’. J. C. Harlequin Plant Bug. By R. I. Smith (Jour. Econ. Entom. ii. (1909) 2, p. 108).—Certain points in the life history of this insect (Murgantia histrionica, Hahn), such as egg-laying habits and so on, are dealt with. From a consideration of its life history it is recommended that this insect should be vigorously fought in the autumn, especially as the hibernated insects are much more prolific than the summer genera- tions.—F’..

Importation of Tetrastichus xanthomelaenae (Rond.). By L. O. Howard (Jour. Econ. Hntom. i. (1908) 5, p. 281).—The European elm-leaf beetle (Galerucella luteola) was imported into America in 1837 and has recently spread to a great extent. It has no natural enemies in America, but in Europe there are two or three egg-parasites of this beetle and its near relatives. Among them Tetrastichus xantho- melaenae was found by Marchal to have stopped the ravages of the beetle on the elms round Paris, where it had been very destructive, skeletonizing the leaves. Dr. Marchal’s description and interesting notes are translated and added to this article. Hggs parasitized by the insect were obtained and conveyed to America in 1907, but the parasites were dead on arrival. Others were obtained in April 1908, and these were successfully reared, and after multiplying were liberated where the bettles and their eggs were abundant. They began to breed and are apparently multiplying rapidly, and the writer considers there is every hope of keeping the beetles in check by means of this parasite’. J. C. Inoculation and Lime in Growing Alfalfa. By H. A. Harding and J. K. Wilson (U.S.A. Hap. Stn., New York, Bull. 818; February 1909 ; figs. and maps).—The authors show that on American soils the application of lime and inoculation with the appropriate nodule-producing bacteria is followed by a greatly increased growth of lucerne (or alfalfa). The inoculation was performed for the most part by means of soil from fields where the bacteria were abundant.—Ff’. J. C. Insecticide, Use of Cyanide as an. By R. S. Woglum and Wm. Wood (Jour. Econ. Hntom. i. (1908) 6, p. 349).—Pouring a solution of one ounce of potassium cyanide in one gallon of water into nests of ants was found successful in destroying them. The solution would probably be much safer to use for such purposes than the solid substance, as there would be no chance of animals picking it up from the ground. He IC: Insects Injurious to Loco Weeds. By F. H. Chittenden (U.S.A. Dep. Agr., Bur. Entom., Bull. 64, pt. 5; figs.).—The insects living on Astragalus mollissimus and A. Lamberti are described. The poisoning of sheep feeding on these plants on the semi-arid plains of the West of — America has been attributed to the insects living upon the plants ; but it cannot be due to them.—Ff’. J. C. Insects that Carry Disease. By L. O. Howard (U.S.A. Dep. Agr., Bur. Entom., Bull. 78; May 1909).—This masterly account deals with the important question of the enormous economic loss arising from the unchecked development of mosquitos and house-flies. It shows that in Seven years 1900-07 an average of over 12,000 people died annually through malaria in the States, and the germs of this disease are carried NOTES AND ABSTRACTS. 809 from one to another solely by mosquitos of the genus Anopheles. Yellow fever in like manner is carried by the mosquito Stegomyia calopus (=Culex fasciatus), and this disease again claims many victims in the United States. The house-fly Howard proposes to call the “typhoid fly’ in order to draw popular attention to the fact that this fly is a very frequent cause of the spread of typhoid fever and other diseases. The best means of dealing with the pests is also treated upon.—F’. J. C. Lagerstroemia indica (Die Gart., p. 152; March 27, 1909).—This beautiful shrub, which is invariably hardy in England and flowers annually, is treated in the more rigorous climate of Germany as a cool greenhouse plant, grown in pots or tubs during the summer out of doors, in winter indoors. It flowers during the late summer. ‘The flowers are rosy red and the leaves are small, not unlike those of the large-leaved myrtle. Gants Lantanas, Choice. By G. T. Grignan (Rev. Hort., May 1, 1909, pp. 204-226 ; plate and 2 figs).—An interesting article, with descriptive list of twelve of the best novelties. The plate represents a dwarf section, ‘Bruant;’ ‘Rayon d’Or,’ brilliant yellow; ‘Radiation,’ deep copper orange; and ‘ Pictavi,’ a hybrid between Lantana Sellowiana and the varieties of commerce, which has proved hardy and is very distinct; flowers, a few bright yellow, the majority bright magenta.—C. 7. D. Light sensitiveness. By W. W. Lepeschkin (Beth. Bot. Centralbl. vol. xxiv. Abth. 1, Heft 3, pp. 808-356; April 1909). The movements of the pulvinus of Mimosa and of the leaflet stalks of Phaseolus vulgaris and Desmodium gyrans have been again investigated. The author’s experi- ments were very ingenious, and should be consulted by those interested in this special subject. His chief point seems to be that darkness affects the permeability of the protoplasmic membrane, which will bring about an alteration in the turgor, and therefore in the shape of the pulvinus or petiolule.—G. F. S.-H. Maple Mites. By P. J. Parrot (Jour. Hcon. Entom. vol. i. 5, p. 811; October 1908).—Fifteen species of mites have been found on various species of Acer in the States. Descriptions of two which form galls on maple are given, viz. Phyllocoptes aceris-crumena Riley and P. quadripes Shimer.—f’. J. C. Marsh Plants. By Paul Bommersheim (Beth. Bot. Centralbl. vol. xxiv. Abth. 2, Heft 8, pp. 504-511; July 1909).—This paper contains some interesting observations on reed thickets and “half-marsh’’ plants. The author collected leaves of the common nettle from a moderately wet situation, from a reed-bed, and from a dry place, and measured the upper surface of ten leaves from each habitat. In plants from the reeds this amounted to 15 square centimetres, from the dry habitat 28 square centimetres, and from an ordinary position 87°5 square centimetres. Those from the reeds transpired least. In reed-beds the air being generally damp there is a distinct probability of fungus infection, and he details the methods of averting this danger. He found that certain 310 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY. leaves of Phragmites which happened to be in contact with a brick wall were wet with dew in the morning, and were subsequently attacked by fungus parasites. The ordinary leaves, which were always in motion, remained dry and were unaffected.—G. F’. S.-H. Mendelism as applied to Sweet Peas. By William Cuthbertson (Gard. Mag. No. 2885, and No. 2886, vol. lii. pp. 181 and 148; Feb- ruary 18 and 20, 1909).—The author briefly sketches Mendel’s laws and shows how they apply to the raising of new varieties of Sweet Peas. He points out how time may be saved in fixing new varieties.—H. B. Metals, Fertilizing Action of. By H. Martinet (Le Jard. xxiii. 528, p. 51; February 20, 1909).—In Belgium experiments are being made by Mons. Henri Michiels and P. du Heen which go to show that metals may act on plants as ferments, stimulating nutrition and germi- nation. Manganese is already adopted as a fertilizer, and now the same properties are claimed for zinc, aluminium, tin, and magnesium. ‘ i. A.W; Miecrocachrys (Bot.

On the other hand, lower organisms, such as diatoms, infusoria, rotifers, continue to move when exposed to a temperature of 5° to 12° below zero. The zoospores of Dunaliella may even be cooled down to a tem- perature between 17° and 22°5° below zero before they cease to move. S. H. W. Mushroom, A poisonous. By G. F. Atkinson (Bot.
