I. — Contributions to a History of the Relation between Climate and Vegetation iji various parts of the Globe. No. 13. — Notes, chiefly Botanical, made during an Excursion from Darjiling to Tonglo, a lofty mountain on the confines of Sihkim and Nepal. By J. D. Hooker, M.D., F.R.S. [Reprinted from the ' Journal of the Asiatic Society' for May, 1849, -with corrections by the Author.] 3Iay 19/^5 1848.— Left Darjiling in the forenoon of this day, accompanied by my friend C. Barnes, Esq. We took with us a small tent, about 15 Lepcha (Sikkim native) and Ghorkha (Nepal) coolies, with as few other servants as possible, these being bad mountaineers, and our route involving much ascent and descent. The direction is W. ; the distance in a straight line little above 12 miles, but occupying good 3 days' march: for we have to descend from Darjiling 5000 feet to the intervening river beds, cross these and several spurs of 1000 — 1500 feet, and thence ascend to a summit 10,000 feet above the sea. The route is wholly within the Himalaya, and always through the forest region ; large trees extending to the top of Tonglo, which is below the lower limit of Alpine pines in this parallel, and of the Arctic vegetation of the loftier Himalaya. A Lepcha carries liis load in similarly formed, but much ruder baskets than those used by the Nepal races, and 1 observed that he uniformly used shoulder-straps, often without the belt across the forehead.* The weight thus transported to great distances * May not the use of the head-strap be a predisposing cause of goitre, by inducing congestion of the laryngeal vessels ? The Lepcha is certainly far more free from this disease than the Bhotea, or than any of the tribes of E. Nepal I have mixed with, and he is both more idle and less addicted to the head-strap as a porter. I have seen it to be almost universal in some vil- lages of Bhoteas, where the head-strap alone is used in carrying both summer and winter crops ; and also amongst the salt-traders, or rather those families who carry salt from the passes to the Nepalese villages, and who have very frequently no shoulder-straps, but invariably head-bands. I am far from attributing all goitre, even in the mountains, to this practice, but I think it is proved that the disease is most prevalent in the mountainous regions of both the old and new world, and that in these the practice of sup- porting enormous loads by the cervical muscles is frequent. It is also found in the Himalayan sheep and goats, which accompany the salt-traders, and whose burthens are supported, in ascending, by a band passing under the throat. VOL. VII. B 2 BELATION BETWP:EN CLIMATE AND VEGETATION is very surprising: on an average our Lepcha loads weighed 100 to 120 lbs. On our return we had the curiosity to weigh the then sodden tent; it was 180 lbs., and had been carried for 10 houi-s both up and down hill in this state. To keep the contents of the basket dry, the Lepcha makes a large liood of bamboo platting, enclosing layers of leaves of Phrynium dichu- tomum; this fits over the head and basket, reaching as low as the hips, but is open in front, and leaves both the upper and lower limbs free. In point of climate Tonglo shares the excessive humidity of the rest of Sikkim, though Avhen viewed from Darjiling it is often seen to be clear when all the northern and much nearer eastern and south-eastern mountains are wrapped in clouds. This arises from its position, and its partial protection from the S.E. or rainy wind. It rises as a long saddle, from a great southern spur of Kunchin-jinga, called Singalelah, which, dividing Nepal from Sikkim, extends from the perpetual snows of perhaps the loftiest mountain on the globe to the plains of India. The di- rection of this ridge is meridional. At right angles to Tonglo, and a little south of it, the Sinchul ridge of 8000 feet meets that of Singalelah, the latter bounding Sikkim to the west, whilst the former shuts it off from the plains of India on the south. Darjiling station is on a ridge projecting N. from Sinchul, parallel to that of Tonglo, which bounds the western horizon. Throughout the greater part of the year the S.S.E. wind pre- vails, rising at sunrise, and its vapours are at once condensed on the forests of Sinchul ; billowy clouds rapidly succeed, and rolling over to the N. side of the mountain, are carried N.W., over a broad intervening valley, to Darjiling. There they bank on the east side of the spurs, and this being cleareii of wood, the accumulation is slow,* and always first upon the few clumps of trees. Very generally by 9 a.m. the whole eastern sky, from the top of Darjiling ridge, is a dense fog, the western exposure enjoying sunshine for an hour or two later. At 7 or 8 A.M. very small patches are seen to collect on Tonglo, which * I have the singulai'ly good fortune to occupy, in Mr. Hodgson's house, the most favourable spot in the station for watching the diurnal march of atmospheric phenomena. My host's house is placed on an eminence 500 feet above the main body of the Darjiling spur, and at its upper or southern extremity. It commands an unimpeded prospect to the N.W. and E., having Kunchin-jinga to the N., and the superb sweep of 80 miles of snow from its summit round by N.E. to E. : to the S.E. Sinchul; and to the W. the Singalelah range, from Kunchin to Tonglo. The station stretches N. in front, as a sharp ridge. I have found it difficult to make old residents, on one or the other side of Darjiling spur, believe that whilst their house on the western slope is enjoying hours of sunshine, the whole eastern side is enveloped in fog. IN VARIOUS PARTS OF THE GLOBE. 3 gradually dilate and coalesce, but do not shroud the mountain for some hours, generally not before 1 1 a.m. or noon. Before that time, however, masses of mist have been rolling over Darjiling ridge to the westward, and gradually filling up the valleys, so that by noon or 1 p.m. every object is in cloud. Towards sunset it falls calm, or a light S.W. wind springs up. In the former case the mists rise, first from the S.E. mountains, and especially if the S.E. wind, exhausted of its surplus vapours, still blows, which raises the clouds first from Sinchul ; and when this is clear, Tonglu breaks through the western mists. If on the other hand a S.W. breeze sets in, or a W. or N.W., Tongl6 clears first. In descending from Darjiling the zones of vegetation are well marked at a little below 7000 feet, or between 6000 and 7000, by — (1 .) The oak, chesnut, and 3Iagnoliacece, the main fea- tures of 7000—10,000 feet. (2.) Immediately below 6500, the Tree-fern* appears {Alsophila gigantea, Wall.) — a widely dis- tributed plant, common to the Ilimalaya from Nepal eastward to the Malayan Peninsula, Java, and Ceylon. (3.) Of palms, a species of Calamus,^ and Plectocomia, the " llhenoul " of the Lepchas. The latter, though not a very large plant, climbs lofty trees, and extends about 40 yards through the forest ; 6500 feet is the upper limit of palms in the Sikkim Himalaya, the Rhenoul alone attaining this elevation. Four other Calami range between 1000 and 6000 feet on the outer hills, some of which are found 40 miles distant from the plains of India. The other palms of Sikkim are, " Simong," — Caryota urens : it is rare, and ascends to nearly 6000 feet. Phanix,'\. a small stemless species, proljably P. ncaulis, Buch. (/*. humilis, Koyle?), which grows on the driest soil in the deep valleys ('' Schaap" of the Lepciias). Wallic/tia§ oblongifolia, Gr. (densifiora, Mart.), a plant liaving a very wide range (Assam and Chittagong). It is the " Ooh " of the Lep- chas, who make no use of it ; Dr. Campbell and myself, however, during a recent journey hi Sikkim, found that it is an admirable fodder for horses, who prefer it to any other green food to be had in these mountains. Areca gracilis, tlie eighth, and Licuala, are the only other palms of these mountains ; but Cycas pectinata, with the India-rubber fig, occurs in the deepest and hottest * Of this I have seen two species in the mountains. X The fruits of all the Calami are eaten by the Lepchas, and the stems of larger species applied to various economic purposes. X The feathery fronds of the Phamix are used as screens in hunting : no other use is made of any part of the plant, except that the yoimg seeds are eaten. § Von Martius, in the last part of his superb work, retains Roxburgh's generic name of Wallicliia for this palm. B 2 4 RELATION BETWEEN CLIMATE AND VEGETATION valleys — the western limits of both these interesting plants. Of Pandanus there is a graceful species at elevations of 1000 to 4000 feet ('• Borr," Lepclia). 4. Tlie fourth striking feature is a wile] plantain, which ascends to above 6000 feet (" Lukhlo," Lepcha). This is replaced by another and rather larger species at lower elevations ; both ripen austere and small fruits, which are full of seed and quite uneatable ; good specific characters may be drawn both from the male flowers, and from the size> form, and colour of the seeds. The commonly cultivated plantain of Sikkim is, I am always assured, an introduced stock (nor have the wild species ever been cultivated) : it is very large, but poor in flavour, and does not bear seeds. The zones of these conspicuous plants are very clearly de- fined in descending anywhere from Darjiling, and especially if the traveller, standing on one of the innumerable spurs which project from the ridge, cast his eyes up the gorges of green on either hand. Firing the forest is easy in the drier months of the year, and a good deal of cultivation is met with on the spurs, at and below 5000 feet, the level generally inhabited by the Lepchas, Limbos, and Sikkim* Bhoteas. The mountain slopes are so steep, that these spurs, or little shelves, are the only sites for habitations between the very rare flats on the river banks, and the mountain ridges, above 6000 feet, beyond which cultivation is rarely, if ever, carried by the Lepchas. The crops are the usual ones of the plains, and the agriculture similar, with one important exception, that the rice is seldom irrigated. This appears the more remarkable, as on crossing the Singalelah range into Nepal, in localities as steep as those covered with rice crops in Sikkim, irrigation is almost universally resorted to. The varieties of grain are difterent, but as many as eight or ten kinds are grown without irrigation by the Lepchas, and the produce is described as veiy good (80 fold). Much of this success is due to the great dampness of the climate ; were it not for this, the culture of the grain would probably be abandoned by the Lepchas, who never remain for more than three seasons on one spot. At the bottom of the valley is a small village of Lepchas, Limbos, and Murniis, aggregated in groups, on one spur, and surrounded with small fields of the usual summer and winter * I apply the term Sikkim Bhoteas to the more recent emigrants from Tibet, who have settled in Sikkim, and are an industrious, well-conducted people. The Bhoteas, again, of Bhotan, to the eastward, rarely reside ex- cept at Darjiling, and deservedly bear the worst reputation of any of the numerous people who flock to this station. They should not be confounded with any other Bhotean tribes of Tibet, Sikkim, or Nepal. IN VARIOUS PARTS OF THE GLOBE. 5 crops of the plains. The Lepcha house is far more roomy and comfortable than that of the others ; it is generally square, built on posts, with a stage in front of the door, and has a low-eaved thatch of bamboo stems, split and laid flat. The walls are of bamboo wattle-work. In all respects it resembles the Bhotea house, but is smaller, and the framework is slighter, it not being worth the Lepcha's while to render his liabitation strong and durable. Both Limbos and Murmis build smaller houses, some- times on the ground, but more frequently elevated ; the roof is of grass-thatch, or occasionally of a piece of bamboo matting. The soil at the bases of tliese hills is very fertile, owing to tlie accumulation of vegetable mould brought down by the rivers, the rapid decomposition of the rocks, and the ashes of the burnt forest. Beneath the mould is generally a stratum of red clay, wliich uniformly covers the hills at all elevations, to a greater or less depth, sometimes even 15 feet. This varies much in quality, apparently owing to the constituents of tlie subjacent rocks. Of the latter some gneisses decompose m ith the greatest rapidity, others resist the elements for ages. A clayey soil covers even the sharpest ridges, retained in its position by the arboreous vegetation; much of it makes excellent bricks, as it contains a very large per-centage of alumina.* A large bamboo (" Pao," Lepcha) is the prevailing plant near the bottom of these valleys ; it attains a lieight of 40 — 60 feet, and the culms average in thickness the human thigh ; it is not spinous, its colour is deep green orpurplisli, and it is used for large water-vessels. Besides this there are nearly a dozen kinds of bamboo known to the Lepchas, all of which liave been pointed out to me. Whether tliese are different species it is impossible to say, for different genera even are too similar in their foliage to be thereby distinguished. Three kinds usually flower; and of these, two bear no leaf on the flowering plant, which dies after seeding. A certain clump of plants seems to flower at the same time, but I could not detect any cause for this isolation of the flowering plants. Bamboos, in the general acceptation of the term (for remotely allied genera bear the same trivial English name), occur at all elevations below 12,000 feet, forming even in the pine-woods, and above their zone in the skirts of the Rhododendron scrub, a small and sometimes almost impervious jungle. In an economical point of view they may be classed into those which split readily, and those which do not. The young shoots of one or more are eaten ; and the seeds of another are made into a fermented drink : but it would take many pages * Nearly 30 per cent., according to the analysis of my friends, J. and C, MuUer, Esqs. 6 IIIXATION BETWEEN CLIMATE AND VEGETATION to describe the numerous purposes to which the various species, even in Sikkim, are put. Gordonia is here common ( G. Wallicliii ?) ; it is an erect and handsome tree, much prized in all parts of the Himalaya, and universally adopted for ploughshares and other purposes requiring a hard wood : it is the " Sing-brang-kun " of the Lepchas, and ascends to 4000 feet. In very dry soils it is replaced by "Sal" (Valeria ro&M*^a), and occasionally by the Pi7ms lotigifolia. " Toon "'( Cedrela tootia), " Simalkun " (Lepcha), and another species (probably C. serrata, Royle), accompany the Gordonia, as do Engelhardtia (which ascends to 6000 feet), and several leguminous trees, Acacice, Dalbergia, Terminalia, and a So7i- neratia. Oaks at this elevation occur as solitary trees, of species different from those of Darjiling. There are three or four with a cup-shaped involucre, and three with spinous involucres en- closing the nut ; these generally grow on a dry clayey soil. Phyllatithiis emblica, Grislea, Symplocos, and other small trees and bushes of the plains, occupy the more open spaces near the streams. Cucurhitacece, Marlea, and scandent Legiiminosce skirt the forest. Fici and Chloranthus with Ferns inhabit rocky places, and an amaranthaceous plant climbs over the loftiest trees ; its abundant inflorescence, like hops, whiten the forest in some places. Sterculice, of two species, are common, as is Pcederia fcetida, which, as well as many Cucurhitacece, peppers, Gnetum, Porana, a few other Co7ivolvulace(B, and many Asclepiadeee, Hoi/a, &c., climb high. Though the temperature of the air was only 77° at noon, these valleys are close and oppressively hot : the streams small and varying in temperature, according to the exposure of their banks ; that of the first we crossed was 70°. Some low steep spurs were well cultivated, though the angle of the field was upvvards of 25° : the crops, chiefly maize, now sprouting. This plant is occasionally hermaphrodite in Sikkim, the bisexual flowers forming a large drooping panicle and ripen- ing small grains ; it is, however, a rare occurrence, and the specin)ens are highly valued by the people. On the ridge a " Seraul " tree (£o?nbax) grows, at upwards of 3000 feet : it is rare at this elevation, or anywhere else upon the mountains. MusscE?ida is conspicuous for its white calycine leaves. A Lysimachia, very like the L. nemorum of Europe, grew beneath it. Descending to another stream, the path led through a low dense jungle of bamboo and figs * of several species. Indeed, * One species of this very tropical genus ascends almost to 9000 feet on the outer range of Sikkim. IN VARIOUS PARTS OF THE GLOBE. 7 the general prevalence of these and their allies, the nettles, is a remarkable feature in the botany of the Sikkim Himalaya, up to nearly 10,000 feet. Of figs there were here five species, some bearing eatable and very palatable fruit of enormous size, others with the fruit small and borne on prostrate leafless branches, which spring from the root of the tree and creep along the ground. A small wild mulberry tree is common in these situations, with three species of nettle,* several of Bcehmeria,\ Procris, Trophis, Celtis, and Conocephalus. Of shrubs there are Randia, Gar- denia, Rondeletia, Citrus ; Rotlera, and other Euphorbiacece, some Sapindacece and Terebinthaceee. ScitaminecB were not above ground ; grasses are rare, as indeed are most monocotyle- donous plants at this season. Of terrestrial OrchidecB there are several species : in the valleys, Dendrobium takes the place of Ccelogyne, the common epiphytical genus at Darjiling. A troublesome dipterous insect (the " Peepsa ") swarms on the banks of the streams ; it is very small and black, floating like a speck before the eye — its bite leaves a small spot of extravasated blood under the cuticle, very irritating if not opened. We crossed the Little Rungeet river at 4 p.m., and found its temperature 69°, and that of the air 75°. Thence we ascended another steep spur from the base of Tonglo, and camped. The night was calm and clear, with faint cirrus, but no dew. A thermometer sunk 2 feet in rich vegetable mould stood at 78° two hours after it was lowered, and the same on the following morning. This probably indicates the mean tempera- ture of the month at that spot, where, however, the dark colour of the exposed loose soil must raise the temperature considerably. May 20th. — Temperature at sunrise 67° ; morning bright, clear over-head, but tlie mountains threatening. Darjiling, perched on a ridge 5000 feet above us, had a singular appearance. We descended from the spur to a narrow ravine, choked with Calami, figs, and the WalUchia, and crossing a stream ascended the Simonbong spur of Tonglo, so called from a small village and Lama convent of that name on its summit. They cultivate here rice, murwa {Eleusine), millet, yam, brindjal, Solanicni me- longena, bhang, Cannabis saliva, buckwheat of two species, fennel and cummin, &c. A white-flowered Rue, Ruta albifiora, is wild at elevations of 3000 to 7000 feet, and is sometimes culti- vated ; it is used for all diseases of fowls, mixed with their food. Celastrus, Myrsine, Embelia, Ardisia, and M(Esa all occur at 3000 to 6000 feet, and we passed through groves of a hand- some shrubby purple Tephrosia in full flower. Near the top of * Of two of these cloth is made, and of a third cordage. The tops of two are eaten, as are several species of Procris ? t Two species yield a fibre : one is the " Poa." 8 KELATION BETWEEN CLIMATE AND VEGETATION the spur Osbeckia and several species of Rubus appeared ; and hence upwards the brambles are very frequent, twelve species occurring between this level and 10,000 feet. They flower at different seasons ; one was bearing large-sized, well-flavoured yellow fruits, as big as raspberries. At noon we arrived at tlie top of the spur, and passing some chaits,* gained the Lama's residence and temple. The latter is nothing more than a rather large wooden Bhotea house raised on a stone platform. As we stopped here on our way down, I shall allude to it afterwards more particularly. Two species of bamboo, " Payong" and "Praong" of the Lepchas, here replace the " Pao " of the lower regions. The former was flowering abundantly, tiie culms, which were 20 feet high, being wholly a diff"use panicle of inflorescence. The " Praong " bears a round head of flowers at the apices of the leafy branches. Wild strawberry, violet, Lysimachia of several species. Geranium, Polygonum, Veronica, &c., announced our approach to the temperate zone. Around the temple were potato crops and peach trees. The potato thrives extremely well in Sik- kim, though I think the root cultivated in the plains of India from the Darjiling stock is superior both in size and flavour. Peaches never ripen in this part of Sikkim, apparently from the want of sun ; the tree grows well at 3000 to 7000 feet, and flowers abun- dantly, and its fruit makes the nearest approach to maturity (according to the elevation) from July to October. At Darjiling it follows the English season, flowers in March and fruits in September, when the scarce reddened and still hard fruit falls from the tree. It is curious that throughout this, the temperate region, there is hardly an eatable fruit except the native walnut.| English cultivated fruits are extremely poor ; the native are confined to the walnut, some poor brambles, of which the " yellow " and " ground raspberry " are the best, some insipid figs, and a very austere crab-apple. The European apple will hardly ripen, the pear not at all. Currants and gooseberries show no disposition to thrive, and strawberries, which grow well, ripen a flavourless * The chait of Sikkim, borrowed from Tibet, is a square pedestal sur- mounted with a hemisphere, the convex end downwards, and on it is placed a cone, with a crescent on the top. These are erected as tombs to Lamas, and as monuments to illustrious persons, and are venerated accordingly, the people always passing them from right to left, often repeating the invocation, " Om mani Padmi hom." t The walnut of Sikkim has an extremely hard shell, whilst that of Bhotau has a remarkably thin one. In both the kernel is excellent, but in Sikkim not worth the trouble of freeing from the shell. Bhotan walnuts are largely exported, and are in all respects excellent. IN VARIOUS PAETS OV THE GLOBE. 9 berry. Vines, figs, pomegranates, plums, apricots, &c. will not succeed even as trees. European vegetables again grow and thrive remarkably well throughout the summer of Darjiling, and tlie produce is very fair, sweet and good, but inferior in flavour to the English. Of tropical fruits cultivated below 4000 feet tlie orange and banana alone are frequent, with lemons of various kinds. The season for these is however very short : that of the plantain might with care be prolonged, but the fruit, as I have said above, is poor ; oranges abound in winter, and are excellent in flavour, but neither so large nor free of white pulp as tliose of South America, the AYest Indies, or AV. coast of Africa. Mangos are broiiglit from the plains; they do not thrive in the valleys ; and tliougli I have seen the pine-apple plant, I never met with its fruit. A singular and almost total absence of the light and heat of the direct rays of the sun in the fruiting season, is the cause of this dearth. Both the farmer and orcliard gardener know full well in England the value of a bright sky as well as of a warm autumnal atmosphere. Without this corn does not ripen, and the fruit trees are blighted. The winter of the plains of India being more analogous in its distribution of moisture and heat to a European summer, such fruits as the peach, vine, and even plum, the fig, strawberry, &c., may be brought to bear well in March to April and May, if they are only carefully tended through the previous hot and damp season, which is, in respect to the functions of flowering and fruiting, their winter. Hence it appears that, though some English fruits will turn the winter solstice of India (November to May) into summer, and then flower and fruit, iieither these nor others will thrive in the summer of 7000 feet on the outer Himalaya, though its tem- perature so nearly approaches that of England, by reason of tlie accumulated evils of its excessive rains and fogs. Further, they are often exposed to a winter's cold no less rigorous than the average of that of London, the snow lying for a week on the ground, and the thermometer descending to 25°. It is true that in no case is the extreme of cold so great liere as in England, but it is suflficient to check vegetation, and to prevent fruit trees flowering till they are fruiting in the plains. There is in this a great difference Ijetween the climate of the central and eastern and western Himalaya, at equal elevations. In the eastern (Kumaon, &c.) the winters are colder and more comfort- less than in Sikkim — the summers warmer and less humid. The rainy season is shorter, and the sun shines so much more fre- quently through the heavy showers that the apple and other fruits are brought to a much better state. It is true that the rain gauge may show a greater fall there, but this is no measure 10 RELATION BETWEEN CLIMATE AND VEGETATION of the humidity of the atmosphere, and still less so of the amount of tiie sun's direct light and heat intercepted by aqueous vapour. It takes no account of the quantity of moisture suspended in the air, nor of the dei)ositions from fogs, which are far more fatal to the perfecting of fruits than the lieaviest brief showers. In the valley of Nepal, Mr. Hodgson informs me tliat at 4000 feet the apple, tliough flavourless, ripens well and is a good fruit, as are two varieties of the European fig ; but these ripen at the same seasons as they do in the plains, the winters being so mild that snow is rare, and never lies. There, however, the plantain and mango do not ripen, nor the orange always. It is too warm for gooseberries, currants, and raspberries, and too rainy for the vine. Apricots may be produced with care, but seldom peaches. The Indian solstices, which are marked by one season of exces- sive drought, and the other of excessive humidity, can never be favourable to a copious fruit market. The obstacles to the pro- duction of good European fruits, either in the plains or hills, are manifest, nor do the tropical kinds flourish as in other quarters of the globe, where the seasons are not so contrasted. Hence there is not one good fruit peculiar to the country, and perhaps but one, which arrives at full perfection -, namely, the mango. The plan- tains are good, so are the oranges and pine-apples, but are less abimdant, and of inferior kinds, and remain a shorter season in perfection than they do in most other equally warm climates. Who tliat has walked the fruit-markets of South America, the West Indies, or Western Africa, has not been struck with the profusion of all the above fruits throughout the year, and of many more besides, which are unknown to India ? On ascending Tonglo we left cultivation and the poor groves of peaches at 4000 to 5000 feet (and this on the E. exposure, wiiich is by far the sunniest), the average level to whicli agriculture reaches in Sikkim ; though both in Bhotan and in E. Nepal cultivation is carried much higher, the more flourishing salt trade, and probably the easier nature of the passes, favouring the formation of fixed iiabitations much nearer to the perpetual snow than in SikkLpi, where the enormous mass of Kunchin-iinga in- trudes its snows considerably south of the main range, and forbids cultivation within upwards of fifteen miles from its summit: its uniform clotliing of forest too allows of no pasturage. Above Simonbong the path up Tongl6 is little frequented ; it is one of the many routes between Nepal and Sikkim which cross the Singalelah spur of Kunchin-jinga, at various elevations, gene- rally lower as they approach the plains of India, and varying from 6000 to 7000 feet. As usual, the track runs along ridges wherever these are to be found, vet-y steep, and narrow to the IX VARIOUS PAKTS OF THE GLOBE. 11 top; through deep humid forests of oak and Magnoliacece, many Lauri, both Tetranthera and Cinnamomum, one species of the latter ascending to 8500 feet, and one of Tetranthera to 9000. Chesnut and wahmt here appeared, with ElcBOcarpus, and some leguminous trees, which however did not ascend to 6000 feet. Scarlet flowers of Vaccinmm serpens, an epiphytical species, were strewed about, and above these the great blossoms of a Rhododendro7i and Manglietia ? lay together on the ground. The Rhododendron Balhousia is a beautiful epiphytical species, growing on the larger oak limbs, and bearing clusters of 6 to 8 flowers of great size ; they are pure w hite, and deliciously scented of lemon. The Manglietia forms a large tree, of which the foliage is very dense, and of a deep shining green. Most of the flowers drop unexpanded from the tree, and have a very sweet aromatic smell ; they are as large as the fist, the outer sepals purple^ the inner pure white. It may be tlie Liriodendron liliifera, Willd. (Rox. ii. p. 654). The fruit differs from both 3Iagnolia and Michelia, and I need not say equally so from Liriodendrofi. In every flower I picked up, there was a grub of a lamellicorn beetle in the centre of the receptacle. Heavy rain came on at 3 p.m., obliging us to take insufficient shelter under the trees, and finally to seek the nearest camping ground. For this purpose we ascended to a spring, called Sim- sibong, at an elevation of 6000 feet. The narrowness of the ridge prevented our pitching the tent, small as it was ; but the Lepchas rapidly constructed a house, and thatched it with bam- boo and the broad leaves of the wild plantain. A table was then raised in the middle, of 4 posts and as many cross pieces of wood, lashed with strips of bamboo. Across this, pieces of bamboo were laid, ingeniously flattened, by taking cylinders, crimping them all round, and then cutting each down one side, so that it opens into a flat slab, several inches across. Similar but longer and lower erections, one on each side the table, formed bed or chair ; and in one short hour, half a dozen men, with only long knives and active hands, had fitted us with a to- lerably water-tight furnished house. A thick flooring of bamboo leaves kept the feet dry, and a screen of these and other foliage all round rendered the habitation tolerably warm. It is a little below this elevation, 3000 to 5000 feet, that great scandent trees of the forests, either wholly enveloping trunks of others or twisting around them, strangle the greatest of these, which, decaying within their folds, leave the reticulated sheath of climbers as one of the most remarkable vegetable phenomena of these mountains. They belong to several orders, and may be roughly classified in two groups— 1. those which merely twine, and by constricting certain parts of their support, produce death ; 12 UI-XATIOX BKTWEEN CLIMATE AND VEGETATION 2. those which form a reticulated mass or network round the trunk, by the coalescence of their lateral branches and rootlets, &c. : these wholly envelop and often conceal the tree they enclose, whose branches appear far above those of its destroyer. To the first of these groups belong many natural orders, of wliicli the most prominent are I^eguminoscB {Bauhinia, Ccssal- p/nia, DaJbergia, Milletia, Butea, 3Iimosa) ; Vines, Pothos, Comhretacece^ Menispermacece, 3Ialpi(jhiacecc, and a few other natural orders. The inosculating ones are almost all figs and WigJitia. At niglit the Lepchas sit late chatting round the fire, wretchedly housed, miserably clad, and very insufficiently fed. A more thoroughly happy people it would be difficult to find any where ; they very rarely quarrel among themselves, and their disposition is singularly cheerful and lively. The flute is their favourite and only musical instrument : it is of bamboo ; has only 4 equi-distant holes, situated far below the mouth-hole, which again is remote from the butt end of the instrument ; and it is very difficult to sound. I have often listened with real pleasure to the simple music of this rude wind instrument ; its low and sweet tones are singularly ^Eolian, as are tlie airs usually played, wdiich fall by octaves : it seems to harmonize willi the solitude of their primaeval forests. A thermometer sunk 2 feet 4 inches in the deep vegetable mould and clay fell to 62°, and stood at 61 "7 on the following morning. Except for the occasional hooting of an owd, the night was profoundly still for sevei'al hours after dark, it being too early in the season for the cicadas. A dense mist slirouded every thing, and the rain pattered on the leaves of our hut. At mid- night a tree frog broke the stillness with his curious metallic clack, and others quickly joining in the chorus, they kept up their strange nmsic till morning. This is called the " Simook " (Lepcha), and like many Batrachians, has a voice less like that of an animal than any organized creature I know. The cries of beasts, birds, and insects are all explicable to our senses, and we can recognize most of them as belonging to such or such an order of animal ; but the voices of many frogs are like nothing- else, and allied species utter totally dissimilar noises. In some, as this, it is like the sound of the concussion of metals, in others of the ringing of steel or brass — any thing but the natural effects of lungs, larynx, and muscles.* 31ay 2\st. — Early this morning we proceeded upwards, our * A very common Tasmauian species utters a sound that appears to ring in an underground vaulted chamber beneath the feet.

The road, still carried up steep ridges, was very slippery, owing to the rain upon the clayey soil, and was only passable from the hold afforded by interlacing roots of trees. At 8000 feet some enormous detached masses of micaceous gneiss rise abruptly from the ridge ; these are covered with mosses, ferns, CyrlandrecB and Begonia', and creeping UrticecB. Such masses occur on all the sharp ridges, and at all elevations ; they project awkwardly through the soil, and are strangely confused and distorted in tlieir stratification, down even to the ultimate lamination of the mica, felspar, and quartz. They are never in situ, and are generally strangely shattered, and evidently not the mere exposed top of any continuous rock forming the nucleus of the mountain. A uniformly dipping stratified rock of any extent would, if raised at the angle of the slopes of these hills, present a precipitous face somewhere; but the ranges of 4000 to 8000 feet ramify and inosculate in all imaginable directions, without presenting a bold face any where near Darjiling. The road cuttings from tiie plains to the Sana- tarium, as well as the landslips, reveal iiighly inclined continuous strata, all variously distorted and much dislocated, but these are only at the foot of the hills. Above 4000 feet all appears a strangely piled mass of gneiss rocks, with no uniformity of dip. Amongst these the red clay lies deeper or shallower as the hollows retain it or otherwise. These rocks are scaled by means of the roots of trees, and from their summit (7000 feet) a good view of tiie surrounding vegetation is obtained.

A very large, broadly cucnilafe spathed Arisfctna first appears at 8000 feet, and is abundant thence to the top of the mountain, where smaller kinds are found at 10,000 feet. It is to be remarked that Lvijiiminosa: are all but unknown in tliis part of Sikkim aljove GOOO feet, except the Parochclu.s com- munis, which however I did not see on this accent. This total absence of one of the largest and most ubir|uit(jus natural orders through 4000 feet of elevation is most remarkable, and charac- terizes much of the Himalayan range of Sikkim. I know of no parallel case anywhere on the globe. In the equally humid fcnests of South Ciiili and Fuegia the order is extremely rare, but species do exist, and the whole flora of those countries is nmch poorer in numl)ers than this. Grasses are also extremely scarce above 4000 feet and below 10,000 feet, always except- ing the bamboos, which by their giant dimensions may be fanci- ftdly supposed to compensate for the want of many herbaceous species : or it may perhaps be stated better thus : — where the proportion of trees is very great, both in nunjber of species and of individuals, arboreous grasses replace the herbaceous sjtecies of less jungly regions. A loathsome tick infests the small bamboo, and a more hateful insect I never encountered. The traveller cannot avoid these coming on his person (sometimes in great numbers) as he l>rushes through tlie forest. They are often as large as the little finger nail, get inside one's dress, and insert the proboscis deeply with- out pain, liurif-d head and shoidders, and retained by a barbed lancet, it is only to be extracted by main force, which is very painful. I have devised many tortures, mechanical and clie- mical, to induce these disgusting intruders to withdraw the pro- boscis, but in vain. Leeches* swarm at below 7000 feet ; a small black species above IJOOO, a large yellow-brown solitary one behjw that. They are troublesome, but cause no irritation. In August and Sep- * I cannot but think that the extraordinary abundance of these Annelides in all the grazing-grounds of Sikkim may cause the death of many animals. Some marked nmrrains have followed very wet seasons, when tlie leeches swarm more than ever ; and the disease in the cattle, described to me by the Lepchas as in the stomach, in no way diflers from what leeches would pro- duce. It is a well known fact that these creatures have lived for days in the fauces, nares, and stomachs of the human subject, causing dreadful suf- ferings, and death in the latter case. I have seen the cattle feeding in places where the leeches so abounded that fifty or sixty were frequently together ou my ankles. 16 RELATION BETWEEN CLIMATE AND VEGETATION teinber these absolutely swarm, and are no less troublesome to man than to the feet of the ponies. The rain continuing heavily, we rested the men by some large pools on the flat. A small Lobelia, Chrysosplenium, Procris, and CaUitriche formed a sward on the banks, amongst which some RauiDicuU grew {diffusus, Wall., and a similar species). A large and handsome Carex flourished in the water. Rauniiculus, though so common a genus literally almost every- where else, is extremely scarce in the temperate and tropical zones of the Sikkim Himalaya ; R. sceleratus abounds in the plains close to the foot of tlie hills, but between that elevation and 10,000 feet I have nowhere seen this or any other species. Here, and probably elsewhere in the Himalaya, the genus is very rare in these zones, though more abundant in the arctic zone above. CrucifercE is another natural order very frequent in the tem- perate and mountainous regions of all the world, except the Sikkim Himalaya. A variety of Cardamine liiisuta? is absolutelv the only plant of this order occurring wild between the plains of India and the summit of Tonglo. CompositcE again are far from represented on the scale thev are everywhere else. Though about Darjiling, where clearances have been effected, the amazing prevalence of Gnaphalmm and Auaphalis. &c., gives an appearance of usual abundance of Com- positcE, these very species will be found elsewhere scarce in the temperate zone of southern Sikkim. Labiatce are also poorly represented, except in clearances. As far as I can guess, this paucity of representatives of orders for which the temperature of the Sikkim Himalaya is admirablj' adapted, can best be attributed — (1.) to the uniform luxuriance of the arboreous vegetation, and the absence of either precipices or naked spots of any kind. (2.) to the htmiid atmosphere ; for some of these groups, as LeguminoscE , arc very rare in equally temperate climates which, in respect of humidity and equabilitv of temperature, can be compared with Sikkim, namely, New Zealand and Fuegia. There, as here, Cruciferce, Compositce, Ranunculi, Labiatce, and above all, LeguminoscE and grasses, are very rare in the forest region. Our ascent to the summit was by the bed of a watercourse, now a roaring torrent, from the heavy and incessant rain. A small Anagallis (like tenella) and a scapeless Primula grew by its bank, also some small Carices, and Hemiphragma. The top of the mountain is another flat ridge, with depressions and broad pools or small lakes, in which grew an Iris. A square platform, raised by the Surveyor General (whose party were the only Europeans wiio had previously to ourselves visited this IN VARIOUS PARTS OF THE GLOBE. 17 mountain), which had been cleared from jungle only eight months before, was already fast getting choked with bamboo and various trees. Upon the very top, though only about 500 feet above the flat, the number of additional species was great, and all betokened a rapid approach to the alpine region of the Himalaya, though large forest trees still abounded. In order of prevalence the trees are, — Rhododendrons of three species. (1.) i?. arboreum, var. roseum, in large bushy trees, 40 feet high. These ramify from the ground, the lower branches being long and spreading, and the apices of all loaded with a superb scarlet inflorescence. (2.) H. barbatum, a tree of nearly the same height, but not so spreading ; flowers as copious and beautiful, but foliage brighter, more luxuriant and handsomer. (3.) R. Falconeri, in point of foliage the most superb of all the Himalayan species ; trunks in- clined, 30 feet high, branching but little, bark very smooth and papery. Branches naked, except at the apices, where clusters of white flowers are borne ; the corollas are 10 cleft, and the stamens numerous. Leaves 18 inches long, very thick, above deep green, underneath wrinkled and covered with a rich, deep chesnut-brown tonientum. Next in abundance to Rhododendrons are shrubs of Limonia, Symplocos, and Hydrangea, forming small trees ; there are still a few Magnolias, ^ery large Pyri, of three species, and yew,* the latter 18 feet in circumference ; besides these, Buddleia, not in flower, Picris, Andromeda, Olea, Celastrus, Cerasus, and Daphne cannabina. A white flowered rose, R. sericea,^ was very abundant, growing erect, its nu- merous inodorous flowers pendent, apparently as a protection from the dashing rair). Sphcerostemyna, Sabia, Stauntonia, and Clematis montana ^ were the prevailing climbers. I met with a cucurbitaceous plant at this great elevation, a Smilax and Asclepiadeous geims. A currant was common, always grow- ing epiphytically on the trunks of large trees. Two or tliree species of Berberis and maple, I think, nearly complete the list of woody plants. Amongst the herbaceous and smaller shrubby plants were many of great interest, as a rhubarb, and Aconitum i)almahim,\ a very pretty species, which, as well * The red bark of the yew is used as a dye, and for staining the fore- heads of the Brahman Ghorkhas in Nepal. t This is the only species of rose occurring in Southern Sikkim. j Probably Bikh is yielded by various Aconita. The name of both the Sikkim Aconites is Bikh-gniong, by Lepchas and Bhoteas, who do not dis- tinguish the two species by the roots. Another far more powerful Bikh is yielded by a plant of the order Composita, which I have gathered abun- dantly at 10,000 and 9000 feet ; and it requires care to distinguish its root from that of the Aconites. When mixed, the Bhoteas could not separate them. VOL. VII. C , 18 RELATION BETWEEN CLIMATE AND VEGETATION as various congeners, yields the " Bikli" poison of E. Nepal, Sik- kini, and Bhotan.

GraminecB were very few in number, but a large Carex covered the ground, amongst the bamboo. Still tlie absence or rarity of several very large natural families at this elevation, which have numerous representatives at and much below the same level in the Western Himalaya, indicates a certain peculiarity in Sikkim. These are the following : — Ra- nunculacecE, Fumarice, Cruciferce, Alsiiiece, GeranicE^ Legu- mi?iosce, Potentilla, Epilobium, Crasstdacece, Saxifragece, Um- helliferce, Lonicera, Valerianece, F>ipsacece, various genera of Compositce, Cumf>anulacece, Loheliacece, Gentiance, Boraginece, Scropliularinece, Prirmdacece, Gramitiece. All the above ai'e genera of the north temperate and subarctic zones, which affect a much higher level in this part of Sikkim than in the Western Himalaya or Bhotan — the difference in this respect being very much greater than the small disparity of latitude will account for, or tlian the (if there be any) difference of mean temperature, for the snow-line is certainly very little different here from that of the N.W. Himalaya. On the other hand, certain tropical genera are more abundant in the tempe- rate zone of the Sikkim mountains, and ascend much higher there than in the Western Himalaya. Of this fact I have cited conspicuous examples in the palms, plantains, and tree-fern ascending to nearly 7000 feet, and in the presence of many other orders at great elevations, as figs, peppers, Lauri, tfec. ; and to these could be added many others, none more remarkable than Balanophora, bf which there are several species above 4000 and even 6000 feet, one ascending to 11,000 feet. This ascent and prevalence of tropical species is due to the humidity and the equability of the climate in this temperate zone, and is perhaps the direct consequence of these conditions. An application of the same laws accounts for the extension of similar features so far beyond the tropical limit in the Southern Ocean, where various natural orders which do not cross the 30th and 40th parallels of N. latitude, are extended to the 55th in Tasmania, New Zealand, the so-called Antarctic Islands south of that group, and to Cape Horn itself in Fuegia. The forest region, encroaching so far upon, and in fact cover- I>f VARIOUS TARTS OF THE GLOBE. 19 ing the temperate zone of the Sikkim Himalaya, and the snow- level not being proportionally higher, it follows that, cceteris jjaribus, the belt occupied by upland alpine and Arctic species is more confined, and in all probability less prolific in species, tlian it is in the N.W. Himalaya. Of this the rarity of Pines (themselves indices of a severe drought in tlie air or soil) would appear to afford a proof; for between the level 2500, the upper limit of the P. longifoUa. and the Taxiis, 10,000, wliicli also coincides with the lower limit of Abies, there is no coni- ferous tree whatever in Southern Sikkim, except on the moun- tain faces immediately subtending the perpetual snow ; and there they descend 1000 feet lower. There are only six species of Coniferce, including Taxus and Juniperus, in this part of Sikkim, of which two are not common to the N.W. mountains, and none are by any means abundant. We encamped amongst the Rhododendron trees, on a spongy soil, of black vegetable matter, so oozy that it was difficult to keep the feet dry. The rain poured in torrents all the evening, and this, the calm, and wetness of the wood prevented our enjoy- ing a fire. Except a transient view into Nepal, a few miles west, of us, nothing was to be seen, the whole mountain being wrapped in dense masses of vapour. Gusts of wind, not felt in the forest, swept over the gnarled and naked tree tops; and though the tem- perature was 50°, tliis produced cold to the feelings on walking about, and being exposed to it. Our poor Lepclias were miserably off, but always happy under four posts and a bamboo-leaf thatch, and witli no covering but a single thin cotton garment. They crouched on the sodden turf, joking with the Hindus of our party, who, though supplied with good clothing and shelter, were doleful companions. I made a shed for my instruments under a tree ; Barnes, ever active and ready, floored the tent with logs of wood, and I laid a " corduroy road " of the same to my little observatory. During the night the rain did not abate; the tent-roof bagged and leaked in torrents, so that we had to throw pieces of wax- cloth over our shoulders as we lay in bed.

Two of the Hindus crawled into the tent during the nigiit, with fever and ague.* The tent being too sodden to carry, we had no choice but to remain where we were, and there being * It is a remarkable fact that both the natives of the plains under many circumstances, and the Lepchas when sufi'ering from protracted cold and wet, take fever and ague in sharp attacks.

Observing the track of sheep, we sent two Lepchas on the scent, who, after being absent the whole day, returned from some miles west in Nepal, with two sheep and as many lambs. The shep- herds were Goorongs of Nepal, who were grazing their flocks on a grassy mountain top, from which the woods had been cleared ; probably by fire. These to the Lepchas were a great boon, but the Hindus would not touch the flesh, and several more sick- ening during the day, we had the tent most uncomfortably full.* Our inability to obtain a view was extremely disappointing, the mountain commanding a superb prospect. It embraces nearly 100 miles of the snowy range, from the far west in Nepal to Kun- chin-jinga due north and its five sister-peaks, varying from 20,000 to 28,000 feet, and from which an uninterrupted succession of snowy ridges sweeps round to the east. The culminant jioints rise, several to 22,000, and many to upwards of 19,000 feet. Chamalari, in Tibet, rears its head above the eastern amphi- theatre of snows at a distance of 80 miles. S. E. are the sub- Himalayas of Bhotan, and all between are the billowy mountain masses of Sikkim. South, the eye sliould have ranged over the plains of India, the courses of the Teesta, the Konki, the Cosi, and the innumerable smaller streams which debouche on the plain. During the whole of the 22nd, from 7 a.m. to 11 p.m., the thermometer never varied 6*5 degrees, ranging from 47*5 in the morning to 54°, its maximum, at 1 p.m., and 50*7 at night. At 7 the following morning it was the same. A ther- mometer sunk 2 feet 6 inches in deep vegetable mould and clay, maintained for two days the constant temperature of 50*7 (alt. 10,000 feet — May). In spite of the heavy rain and fog, the dew point was always below the temperature, at which I was sur- prised, for more drenching weather could not well be. The mean dew point was 50*3, and consequent humidity 0"973.f These observations, and those of the barometer, were taken some 60 feet below the summit, to which I moved the instru- ments on the morning of tlie 28th. At a much more exposed spot the results would no doubt have been different. A thermo- meter there sunk to the same depth as that below stood at 49 • 7 ; or one degree colder tlian 60 feet lower down.

The air, wliich was always foggj', was alternately cooled and heated, as it blew over the trees, or the open space we occupied, sometimes var^'ing 5° and 6° in J hour. Whenever a lull occurred the fog was sensibly heated by the sun's rays. The number of mosses, Hepaticce and Lichens, growing near and on the summit, is very remarkable. Tliere were various species of ferns, and a small Agaricus grew on decayed twigs ; lichens infested the naked branches of the rose, berberry, and cherr}\ The trunks of both the Rhododendrons, owing to their smooth papery bark, and the bamboo, are remarkably free from cryptogamic vegetation. Having partially dried the tent in the wind, we commenced the descent, which, owing to the late torrents of rain, was most fatiguing and slipper}^ ; it again commenced to drizzle at noon, nor was it till we had descended to 6000 feet that we emerged from the region of clouds. There I met Avith a species of Balano- phora * pushing through the soil ; it is a new species, monoicous, the earliest flowering of any in Sikkim, and may be distinguished from its congeners by its cyathiform involucre round the middle of the pedicle. By dark we arrived at Simonbong, having descended 5000 feet at the rate of 1000 feet an hour, and here we were kindly received by the Lama, who gave us his temple for the accom- modation of the whole party. We were surprised at this, both because the Sikkim authorities had falsely represented the Lamas as very averse to Europeans, and because he might well have hesitated before giving ingress to a promiscuous horde of some thirty people into a sacred building, where the little valuables on the altar, &c. were quite at our disposal. He made but one request, that the Hindus should not smoke their hookahs inside.

Many of these are of excellent masonry, Chinese in architecture, gorgeously decorated, and, for so poor a country, richly endowed. During my more recent travels in Sikkim I have visited many, been an inmate in the monasteries, and met with the greatest kindness and hospitality from the good fathers. As the first European who had ever lived with the monks, this was the less to be expected.

It consists of one large room, with small sliding shutter windows, raised on a stone foundation, and roofed with shingles of wood ; opposite the door, which is at one end (the east), the altar is placed, of wood, chequered with black, white, and red diagonally ; to the right and left are shelves with a few MS. books, wrapped in silk ; a model of Symbonath temple at Nepal, in wood ; a praying cylinder, and some implements for common purposes, bags of juniper, &c. On the shelves are English M'ine-bottles and glasses, with tufts of Abies Wehbiana, Rhododendrons, and peacocks' fea- thers. On the altar seven little brass cups are ranged, full of water ; a large shell carved with the sacred lotus : a brass jug from Lhassa, of beautiful design, and a human thigh-bone, hollow and perforated through both condyles. The shelves above con- tained various trifles, clay ornaments and offerings, and little Hindu idols brought from the Hurdwar fair. Facing the altar is a bench and a chair, and on one side a huge tambourine, with two curved iron drum-sticks. The bench was covered with mysterious implements, bells handsomely carved with idols, censers with juniper-ashes, the dorge which the priest holds in his hand during service, and various water-vessels ; on the stool or chair was a large platter, with a brass egg-cup inserted in it. Of these articles, the human thigh-bone is by much the most curious ; it is very often that of a Lama, and the longer they are the more value is put upon them. As, however, the Sikkim Lamas are burned, these relics are generally procured from Tibet, where the corpses are said to be cut in pieces and thrown to the kites, or into the water. The Lama was consecrated at Cimngachelling, one of the oldest Sikkim convents (it has existed for three centuries), and unfortunately was not an educated or intelligent fellow. Two boys usually reside in the temple, and their beds were given up to us, which being only rough planks laid on the floor, proved clean in one sense, but contrasted badly with the springy couch of bamboo the Lepcha makes, which renders carrying a mattress or aught but blankets superfluous. May 24.th. — We were awakened this morning by the dis- coi'dant orisons of the Lama ; these commenced at sunrise, by the boys coming in and beating the great tambourine close to our ears for several minutes, then blowing the conch-shells, and finally the thigh-bone, each for as long a time. Shortly the Lama entered, clad in scarlet, shorn and barefooted, wearing a small red silk cap. He walked along, slowly muttering and groaning his prayer, to the end of the ajiartment, whence he took a small red bag in which were a brass bell and dorge. Sitting down he LV VAKIOLS PAKTS OF THE GLOBE. 23 Commenced matins before the chair with the brass cup, which he filled with water and placed again in the platter — took off' his beads and continued counting them or beating tlie bell, uttering- most dismal prayers in a very deprecatory tone, of whicli " Maliva, oh Maliva," was the burden. After various disj)o.-als of the water- jugSj cups, and platter, wliich were filled and refilled, rice added and sprinkled about, a large bell was violently rung for some minutes, himself snapping his fingers and uttering most unearthly sounds. Having put away those instruments, incense was brought, of charcoal with juniper-sprigs. This was swung about, and put tiirough many evolutions, and finally, with the water, thrown out of the window, when the morning service was concluded, to our great relief, as the noises were quite intolerable. After breakfast the Lama came to visit us, bringing rice, a few vegetables, and a large basket of fermented Murwa (seeds of Eleusina coracana) : the latter is invariably given to the traveller, either in the state of the fermented grain, or more conmiunly in a bamboo jug filled with warm water and grain ; the fluid sucked through a reed is a refreshing drink.

AVe reached Darjiling late in the evening, and again drenched with rain ; our people, Hindus and Lepchas, imprudently tarried for the night in the valleys below.

A more interesting and attractive companion in this respect than the Lepclia I never lived with : cheerful, kind, and patient with a master to whom he is attached ; rude but not savage, ignorant and yet intelligent ; with the simple resource of a plain knife he makes his house and furnishes yours, with a speed, alacrity, and ingenuity that whiles away that well known long hour when the weary pilgrim frets for his couch. In all my dealings with them they have proved scrupulously honest. Except for drunkenness and carelessness, I never had to complain of any of the merry troop, some of whom, bare- headed and bare-legged, with absolutely nothing but a cotton garment and long knife, followed me for three months on a recent occasion, from the scorching plains to the everlasting snows. Ever foremost in the forest or bleak mountain, and ever ready to help, to carry, to encamp, collect, or cook, they cheer on the traveller by their unostentatious zeal in his service, and are spurs to his progress ; for who would not go forwards where such followers are behind ? II. — Mode of Heating adopted at Porthgwiddeti, 7iear Truro, By the Rev. T. Phillpotts, F.H.S. (Communicated Sept. 29, 1851.) The accompanying plans and sections refer to a forcing-pit, orchid-house, and cutting-frame, erected at this place, under my own direction, early last year. Their success has been so com- plete in all points, that I place the details at your disposal, that others may, if they think fit, pi'ofit by my experience. Real usefulness rather than display has been my object, and I lay no claim to novelty or invention beyond what a practical rather than a scientijic adaptation or modification of the plans of others, avoiding as far as possible their defects, may deserve. Without discussing other systems, their merits and demerits, I will only say, that I have for many years paid much attention to the best method of constructing and applying heat (especially bottom heat) to horticultviral buildings. The Tank system and the Polmaise have both been tried by me at different times (under the personal advice of Messrs. Rendle and Meek), honestly and without any prejudice ; but after the expenditure of a good deal of time, trouble, and money, I have arrived at the conclusion that an apparatus consisting of hot water in pipes, with open troughs connected with them, affords the simplest and cheapest, ADOPTED AT PORTHGWIDDEN, NEAR TUURO. 25 because the most certain and efficient means of heating I have yet seen. The range consists of — I. A forcing pit,* 42 feet by 8 feet, divided into three com- partments A, B. C. of three lights each. II. An orchid house of the same length, 10 feet wide, in two divisions. III. A row of striking frames on the north side, to which heat may be given at pleasure. The whole M'as put to work at Easter, 1850, when pit A. was planted with cucumbers (Cuthill's black and Snow's white spine I find the best), and since that time we have had a constant supply of the finest fruit, which has in every instance at five suc- cessive exhibitions carried off the first prize. Pit B. was filled with vines in pots, which were ripened and succeeded by melons. In December a fresh lot of vines was introduced, which produced the finest crop of grapes (in pots) I ever saw. Some of the pots had as many as 14 and 15 bunches, well coloured. These were cut in May and June, from vines which were most of them only 15 months old, and on their removal melons were planted, of which there is now (Sept. 29) a good crop, nearly ripe. Pit C. has already ripened ofi'a fine early crop of melons, one of « hich obtained the Bronze medal at the Botanic Society's exhibition in the Regent's Park. It is now occupied as a cool pit, with plants of various kinds. The whole is heated by a single 24-lnch ribbed boiler of Burbidge and Healey's pattern (they have in my opinion spoiled their newly improved (?) one by getting rid of the central tube). Perfect command of heat is given by the Sylvester fire-doors and dampers, which need no praise from me : they are admirable, and may be used with almost any boiler. The setting of the boiler, as recommended by Messrs. Burbidge and Healey, is a great advantage : the fuel does not come in contact with any of the iron work, every inch of which is, however, exposed to the action of the heat, and a system of slow combustion, regulated by dampers and by a flue, which descends a little before it goes off to the stack, economises fuel to a most surprising degree. The pipes are 4 inclies in diameter, and 1 foot from centre to centre. The open ti'oughs are cast with a pipe at each end to fit into the sockets ; they are 6 feet long and 9 inches wide at the top ; depth 4 inches, with a shoulder cast in each rim to enable us to cover them with common slate, when less moisture is required ; if a very dry heat is wanted, a little sand strewed * The pits are really only G feet wide, but in the drawing I have made them 8 feet, as I find I have such a superabundance of heat that I now wish for the extra width. This is the only improvement I can suggest, after 18 months' trial. 26 MODE OF HEATING over the slate keeps all tight. The heat is regulated not by expensive cocks or valves, which contract the flow, and are liable to get out of order, but by series of cast-iron cisterns M'hich supply the place of elbows, and being cast with one, two, or three sockets of the same bore as the pipes, may be plugged off with a conuuon piece of wood, with a little cloth wrapped round it, so as to clieck or entirely cut oft" the supply from any part which may not need it. But the most perfect system of heating would be vain without good ventilation night and day. If my theory is correct, the air of plant houses of this description should be in direct pro- portion to the light, the moisture, and to the heat. This is best attained (where the quantity is easily controlled) in a small house, for the temperature must not be lowered too much by the admission of external air, while, on the other hand, it must not be dried by artificial heat. To obviate this difficulty, you will observe an air chamber between the two buildings, wliich has its opening at a lower level, near the ash pit ; from this chamber several small drains open into the pits, &c. 6 inches above the floor, with gratings of (about 6 inches square) per- forated zinc. From these a constant supply of fresh air in small and broken quantities arises, so that no strong draught is created ; and this, passing over the surface of the pipes, under which it enters, loses its chill, while the open troughs supply it Mith moisture ; these are constantly open, but may be closed if necessary. Tliere are also ventilators in the front and back walls, and at the top of the orchid house. It will be perceived that the ridge piece is raised above R. the roof, the south side of which carries a roller for sun-blinds, while the north side has a row of luft'er boards, which are opened and shut at pleasure, by balance weights within. The front of tlie orchid house is fitted with Plartley's patent rough plate-glass, which answers admirably without diminishing tlie light ; indeed, a blind is still needed for tlie orchids in very bright weather. One word as to drip — by adopting the pattern of sash-bar given by Mr. Lyons in his work on Orchids, this is entirely avoided, even when the house is saturated with moisture, and a cold Mind blowing without. ADOFTED AT rORTHGWlDDEN, NEAll TKLTtO. 27 It may be objected that the cold in this neighbourhood is not excessive, the thermometer never falling below 18°, and rarely within 10° of that point. I may, however, say that we have never worked to our full power, and my gardener is so convinced of the sufficiency of the boiler, that he wishes to heat another range of store pits from the same, which he says he could easily do with little or no increase of fuel. AVith these observations I leave the plans in your hands, be- lieving that with such modifications as circumstances may require they will be found practically useful and economical, getting rid in a great measure of the nuisance and uncertainty of dung beds, and doing the real work of the forcing ground in a simple and efficient manner. Such successful results can only be expected where the gardener not merely understands but loves his business. It is but common justice to add, that I have the good fortune to be so assisted, and that I highly value the care, attention, and zeal with which my plans have been carried out. Note. — I must not omit mention of the cucumber pits erected for Mr. Ludlow, at Heywood House, Wilts, from which I re- ceived much assistance, and, indeed, tlie first idea of my own range. They failed, however ; at first from an excessive mois^ ture, caused, as I believe, by an insufficient supply of air. 1 have no doubt Mr. Crane, tlie intelligent gardener, has long since remedied this. It may be useful to add that the entire cost of my building, including everything, was 160/. The consumption of fuel to keep it constantly working is about nine tons of culm (jjrice here 14*. per ton) per annum.

SCHLEIDEJJ'S THEORY OF AGraCULTURE. III. — Dr. Schleidens Theory of Agriculture. By the Rev. M. J. Berkeley, M.A., F.L.S.* The volume before us, whose full title we have given below, may either be considered as a distinct work in itself, or as a single volume out of three, constituting a cyclopaedia of theoretic natural history for the use of agriculturists, comprising physics, inorganic and organic chemistry, meteorology, mineralogy, geology, the knowledge of soils and manures, the physiology of plants and animals, and the theory of rational husbandry. It is not our intention to advert to that part of it which relates to the physiology of plants and animals ; it is to the third part only that we purpose to direct the attention of our readers, premising that in the prospectus issued by the publishers it is considered so complete as to render any more especial rules of husbandry un- necessary, inasmuch as the principles involved are so clear and certain as to enable every one who has any interest in the matter to apply them at once as any particular case may arise. While, therefore, it modestly proclaims itself merelj' as theory, it in point of fact professes itself as thorougiily practical. It is in this point of view, therefore, that we think a fair abstract, conveyed as mucii as possible in the words of the author, may prove not uninteresting nor unsuggestive of practical good, though we are not prepared at once to adopt the views of the learned author, which are greatly at variance with many notions which are generally current amongst cultivators. Dr. Schleiden, though often paradoxical, is always an able reasoner ; and whatever we may think of his new theory of the impregnation of plants, he has so many titles to merit as an excellent anfl acute observer, that whatever he advances is entitled at least to a candid examination. The main position amidst others of various degrees of import- ance contained in the theory of the cultivation of plants is simply this, that manures do not act immediately on vegetation by means of their organic contents, but by reason of the inorganic substances which they involve. The organic portions, however, perform a part absolutely necessary to the process, as they retain the inorganic portions in their tissues, and by their power of absorption of matters contained in the surrounding atmosphere render them available for nutrition. * Die Physiologic der Pflanzen und Thiere uiid Theorie der Pflanzen- cultur fiir Landwiithe bearbeitet von Dr. M.

SCHLEIDEN'S THEORY OF AGRICULTURE. 31 Without further preface, we proceed with our account of the argument. There is a great difference between experience and observa- tion ; the latter merely indicates the external relation of one phenomenon with another as regards space and time ; the former their intimate connection in point of cause and effect. Without experience in this true sense of the word there can be no theory. "What is meant therefore in the present volume by Theorj'^ of Agricultvire is only the apposition of those sciences which can alone place an intelligent cultivator in a condition to make real and useful experiments, and when a sufficient quantity of these are collected, and not till then, a theory of agriculture in the real sense of the phrase will be possible. At present we must be content by means of chemical and physical science to make agri- cultural experience possible. The first question which arises is what are cultivated plants or plants of husbandr}', and in what respect do they differ from wild plants. It is quite self-evident that all laws to which wild plants are subject, hold good of cultivated plants so long as their inapplicability is not proved by intrinsic difference of nature. The greater part of writers on agriculture are wholly incom- petent to say whether cultivated plants are under more or less favourable circumstances than wild plants. The first thing which strikes us about those plants whose cultivation is carried on on a large scale is that they comprise a very small portion of the species which are distributed over the earth. Out of the ten thousand species of grasses scarcely twenty species are exten- sively cultivated ; of the immense family of Papilionaceous plants, perhaps twelve ; half a dozen Crucifers ; scarce as many Umbellifers, Chenopods, and 8olanads : besides a sprinkling of species cultivated in tlie tropics with which we are less familiarly acquainted. Out of 300 families, consisting of some 200,000 species, we have mentioned nearly all that come within our present scope. These plants may be divided into two different groups ; those of which we do not know witli certainty the wild state, and those whose origin is well ascertained. The most important cereals for instance, as Indian Corn, Rice, Wheat, Rye, Oats, and Barley, are never met with truly wild. All the researches of travellers in America after the wild state of the Indian Corn have been vain, and our European species which are supposed to have been derived from the East have never been found in coun- tries except where it was more than probable that tiiey had been introduced by the hand of man. The wild originals seem to have perished before what are called the historical ages. Nor indeed do they establish themselves in general as wild plants ; 32 DR. SCIILEIDEN'S THEORY OF AGRICULTURE. after two or three more or less abortive efforts they completely vanisli. As regards tlie second group, how different are the roots of our cultivatetl Carrots, Turnips, «S;c., from tiie dry, useless produce of the wild plant ! What resemblance between our CauliHowers, Savoys, and Cabbages, and the juiceless plants of Brassica oleracea from the Dunes of the Baltic, which, nevertheless, is the origin from which they sprang ? The wild Potato of Chiloe has a small, greenish, nauseously bitter root, and other instances might be alleged. The characteristic, then, of agricultural plants consists not in what distinguishes them as species, but in that which separates them as varieties from the typical form. Moreover the natural orders to which they belong are amongst those which have an especial tendency to form varieties, '\i\ which, therefore, the distinction of species is extremely difficult, and requires great circumspection. To understand then the peculiarities of these plants we must become well acquainted with the mode of origination of varieties and subspecies. If the seeds of a double Dahlia are sown, a few only of the produce resemble the parent, the greater part differ from that and from each other ; and when the same circumstances take place in the second generation the plant which exhibits them is called a variety. The Cauliflower, for instance, was originally a variety of the wild Cabbage. If proper attention, however, be paid to the soil, the seeds reproduce the variety with certainty, and it is then called a subspecies. But few varieties arise from mere cliange of soil or climate : the flesh-coloured Hi/di-angea becomes blue in certain soils ; some blue flowers become red when grown near anthills from the effect of the formic acid ; and in a dry situation the lliband Grass of our gardens is produced from the common green form. Changes of colour and increase or decrease of vigour are effected, but new varieties in general do not arise. Where plants are propagated by buds varieties more frequently originate. Potatoes for instance alter more or less in different soils, and Strawberries degenerate where they are allowed to spread extensively from runners. The main source, however, of varieties and subspecies is from seed. Art indeed exercises a certain degree of power over their production, so that the expected produce is almost matter of cal- culation where a sufficient degree of skill is exercised. If tiie seeds of a variety are sown with due attention to similarity of soil and treatment, there is almost a certainty that some individual will exhibitHhe characters of the variety. If amongst these that one is selected which is nearest to the mother-variety, the new gene- ration will afford a greater number of individuals true to the DR. SCHLEIDEX'S THEORY OF AGRICULTURE. 33 desired characters, and if tlie experiment be continued through a series of years, the variety at last will constantly produce plants like itself, and will be then an established subspecies. The necessary condition is, that the same circumstances of soil and cultivation should be continued through the whole pro- cess, and it is clear that by inverse treatment a plant may be made to revert to its original type. The object tiien of field-culture is not plants as species, but as varieties. And as such they may be arranged in three classes. With the first of these, which regai-ds mere general vigour of growth, as in varieties of real or artificial grasses and forest trees, we have at present little interest. Preternatural development of certain parts and modifications of chemical action are much more to our purpose. The following list comprises the most familiar instances : — A. Preternatural development of certain Parts. a. Boot . . Turnips. b. Stem . . Kohl-rabi, Cauliflower, Flax, and Hemp. c. Leaves . Cabbages. d. Buds, especially subterranean. Potato. e. Fruit . . Apple, &c. /. Seed . . Cereals, Pulse, and Oil Plants. B. Modifications of Chemical Action with a view to the Multiplication of peculiar Constituents. a. Protein . Cereals, Pulse, and Coleworts. b. Starch . . Potato, Cereals, Pulse. c. Sugar . . Beetroot. d. Oil . . . Oil Plants. The preternatural development of one part supposes peculiarities of chemical action in the whole. What then are the conditions which can induce such modifications ? To this end we must compare the circumstances attendant on natural and artificial growth, which will throw much interesting light on the nutrition of plants, and some other important points of their culture, as for instance the nature of manures. Now there are soils extremely rich in organic substances, as peat bogs or moors. They support a very poor vegetation ; poor in the number of species, their uniformity of habit, and their all but utter worthlessness. There are soils again rich in organic substances, consisting to the depth of 100 feet or more of humus, which support the most luxuriant vegetation, viz., the tropical virgin forests : their richness in species, their variety of forms, and their great utility form a striking contrast to the case just men- tioned. Again, there are soils consisting of lava and volcanic ashes, with scarce a trace of humus, except such as arises from the still undecoraposed remains of the plants which they have VOL. VII. ^ 34 Dli- SCHLEIDIiN'S THEOKY OF AGIUCULTUKK. supportetl, which still are remarkable for their exuberant vegeta- tion, and which have for centuries been equally prolific without any acKlition of manure. Tiie tierra colorada of Cuba, whicli is used for the cultivation of coifee and indigo, is a case in point. Again, there are soils void of humus, which support no vege- tation, or one of the very meanest ciiaracter, as for instance the loose sands of the Sahara. The humus then cannot be the cause of fertility, for we find a very poor vegetation on land ex- tremely rich in humus, and a luxuriant growth on that which is destitute of organic constituents. Nor can the presence of water be the only requisite, for if we ascribe the desolation of the desert to the absence of water, we cannot lay the blame on that in the case of peat bogs. If water be added to the loose sand, as in the forests of tlie German marches, we have a uniform and poor vegetation. There remains but one answer : in the soils destitute of humus it must be the mineral inorganic constituents wliich are the cause of luxiu'iance, and to the same cause must be attributed the fertility of the virgin forests of the tropics, in comparison with the barrenness of the peat bogs, though equally rich in organic matter. Fi'om the very mode of formation of peat bogs it follows that all the soluble mineral constituents are washed out and carried off, whereas in the soil of the virgin forests tliey are stored up, insomuch that the continued cultiva- tion of tobacco for some centuries is required to exhaust tiie alkali of the North American woods. Now if a comparison be made with our cultivated lands, it is the first superficial glance alone which recognizes any necessary proportion between the fertility of the soil and its richness in hunuis. Analysis shows that no such relation exists, but that the goodness of the soil depends upon its inorganic constituents, so far at least as they are soluble in water, or through continued action of carbonic acid ; and the more abundant and various tliese solutions, the more fruitful is the ground. But the matter may be viewed in another light. If we take the Flora of a country, as for instance that of Germany by Koch, which is perhaps the most perfect of its kind, we find plants divisible into two classes, one containing those whose forms are extremely simple and constant, and another those which are rich in remarkable and definite varieties. The latter, with few ex- ceptions, are either Alpine plants, or such as, in our cultivated ground and its neighbourhood, are subjected to the influence of agriculture. This is the most striking when we compare the species of a particular genus with one anotlier, and find that even nearly related species are distinguished in tliis respect according to their natural locality. The one is subject to produce varieties. DR. SCHLEIDEN'S THEORY OF AGRlCULTUrvE. 35 the other extremely constant. Now, certainly, it is not the rich- ness in humus which intluces the multiplied varieties of Alpine plants, or its comparative absence, on the other hand, which causes the poverty of forms in other species. The Alpine plants grow in a soil to which the water contiimally brings down the decomposed elements or the comminuted fragments of the im- pending roclvs. The characteristic of our cultivated fields is equally the richness in soluble mineral constituents, and not the greater proportion of humus. We may now then answer the question : What is an Agri- cultural plant ? It is one which is distinguished from wild individuals of the same species by peculiar qualities which con- stitute its fitness for culture, and which depend upon a modifica- tion of chemical action. By cultivation, in its confined sense, to the exclusion of all cases of mere promotion of luxui'iant growth, is meant the pro- duction of certain definite qualities in particular individuals. There is however another end in view, namely, that of associa- tion, to the exclusion of all other plants. Even where no pecu' liar qualities distinguish the plant under culture from the wild state of the species, such association is necessary to save the labour of the collection of scattered individuals. Nor is this necessary association without its consequences. Most men con- sider plants so collected as in a far more favourable situation than they occupy by nature ; but the fact is precisely contrary ; for the greater part of cultivation consists in restoring the fer- tility which has been impaired by such association. Although it is improbable that different natural laws prevail in the nutrition of cultivated plants from those which are wild, we must not take this for granted, but put it to a strict proof, especially since the most erroneous notions on this subject are prevalent. The facts which follow are collected from Loudon's Encyclo- paedia : — ■ Up to the 35th degree of latitude, on either side of the equator, the farmer depends not on dung, but on irrigation ; from thence to the 45th degree manure accompanies irrigation, but by no means universally ; from thence to the 67th degree, which is about the limit of cultivation in Norway and Sweden, the ground is drained and manure employed. In tlie southern hemisphere this latter region is of little importance, while the first is of great consequence on both sides of the equator. Three- fourths then of tiie cultivation of the whole globe is quite inde- pendent of manure. In the following countries organic manure is not used, and frequently impracticable from the want of beasts to yield it. D 2 36 DR. SCHLEIDEN'S THEOEY OF AGIUCULTUHE. In the middle of Russia the corn which supplies the market of Odessa is produced year after year on the same ground without any manure. The straw is simply burnt. Sometimes indeed the produce is only six or seven fold, but occasionally very rich. The stems of the wheat are frequently as thick and tall as reeds, and the leaves like those of Indian corn. In some parts of Malaga wheat and barley are grown alter- nately without either dung or fallow. In Arabia Felix raw manure is replaced by water or burnt camels' dung. In Hindostan the ground yields two harvests without manure, the first principally of vetches, the latter of Indian Corn exclu- sively. In the rice districts, comprising a great part of Asia, organic manure is not applied. The Chinese however lay great stress on vegetable ashes, and collect the weeds for burning. In Van Diemen's Land fifteen successive crops of wheat are taken without manure ; the land is then suffered to run wild, and when covered with Acacia scrub the trees are burnt, and the soil is again fit for cultivation. The same is the case at the Cape of Good Hope, and many like instances might be produced. As examples of plants which yield a great produce without organic manure, we may mention Indian Corn, Rice, Sugar-cane, Coffee, Cacao, Banana and Plantain, Manioc and Yam, Cotton, Indigo, and a great portion of Tobacco. In fact the 200 or 600 fold produce of Indian Corn in Mexico without any manure, puts to shame our 12 or 15 fold harvest with every effort of agricultural skill. The following considerations show clearly tiiat in no case do the organic substances contained in the ground perform any direct part in the nutrition of plants. Humus, taken in its widest sense, is nothing more than the undecomposed parts of animal and vegetable substances. Before organic beings appeared on our earth, there could have been no organic mould ; but even supposing such to have been the case, and in whatsoever degree, the earth must long since have been a wilderness had plants lived on organic matter. The organic substances which an animal devours are, to the extent of at least a half, entirely con- sumed by the process of nutrition ; and the more or less rapid combustion of decomposition wherever life has ceased, raises the amount of complete destruction of organic matter to something quite enormous. The process of destruction may be estimated as follows : — For every rod of ground (containing 100 square feet) we may reckon at least 200 lbs. of destructible organic matter, of which 4 lbs., according to De Saussure's direct ex- periment, are changed into Mater and carbonic acid. Taking the surface of productive land in the whole earth, we have 3 millions of square miles, and thus 104 billions of pounds are annu- DR. SCHLEIDEN'S THEORY OF AGRICULTUKE. 37 ally destroyed. The destruction of organic matter by men and animals, according to the observations of Valentin, amounts to one billion annually. And supposing the consumption of fuel by each individual to amount in the year to one cord of wood, on data afforded by the consumption of Germany, without taking into account the extensive natural conflagrations which are so frequent and disastrous in many parts of the world, there is a consumption on this account of 40 billions of dry organic matter. The annual destruction then amounts to 145 billions. Now sup- posing the specific gravity of the matter on an average to be equal to that of water, we have 2^ billions of cubic feet. And since the above mentioned surface contains 1164 billions of square feet, to satisfy the necessary conditions for the nutrition of the vegetable worJd, there must have been 5000 years back lO feet deep of pure organic substance on its surface, supposing nutrition to be dependent on organic matter. The following example will still further explain the author's views. In the year 1844 France possessed, according to sta- tistical reports, 10,709,391 of the large animals, such as horses and beast, 30,859,454 of the smaller, as swine, .^lieep, calves, &c. Now if the daily annihilation of organic matter in the former case be reckoned at 1 1 lbs. per head, and that of the small at 3, the process of nutrition has entirely destroyed in the course of the year 76,789,000,000 lbs. of organic matter, that is six times more than the weight contributed by the whole mass of small and great taken together, reckoning the larger at 1000 lbs., the smaller at 600,* with 50 per cent, of dry organic matter. Now if we suppose that the other animals and plants of France con- tain 600 times as much organic matter, the whole organic material of the country would be consumed by the nutriment of the stock in a hundred years. And the application is easy to the whole universe. It follows then that a process must exist for the sustenance of organic life upon the earth, in due proportion, which must be diametrically opposite to the process of nutrition in animals, and the consequent decomposition ; and as that continually destroys organic matter and changes it into inorganic combinations, as water, carbonic acid, and ammonia, so this must form organic materials out of the inorganic elements. Since this process exists neither in the animal nor inorganic creation, it can be no other than the process of life and nutrition in plants ; and if this is true generally, it is true of those plants which are the object of husbandry. * There must be some error in the numbers here, as an average of 60 would be nearer the truth. The principle, however, remains the same. 38 I>K. SCHLEIDEN'S THEOKY OF AGEICULTUKE. If we reflect again on the constant outgoing from an estate in various forms, and the extremely small quantity of matter \vhich conies in to replace the expenditure, it is easy to see that all virtue would be extracted in a very short time from the land if plants depended, even in a small degree, only on the organic substances ; whereas under good cultivation the ground is con- stantly improved in quality. Indeed, from the observations of the best authorities, it appears that the ground produces three times as much organic matter as it receives. But more than this, the greater part of the organic substance of manure cannot enter into the produce. The land is manured not for the year only, but for a series of years. By far the greater portion passes off by a silent process of decomposition, especially when the land is stirred, into the surrounding atmosphere. Not a tenth part of the organic substance of plants can possibly be supplied by the decay. There is, however, no ground to suppose that this tenth part arises from a different quarter from the remain- ing nine in cultivated plants, and the whole ten in a state of nature. When it was stated above that plants of husbandry are dis- tinguished by an alteration in the chemical process, this did not necessarily imply a change in quality. Wild plants form from water, carbonic acid, and ammonia, albumen, gluten, sugar, starch, oil, &c. The same substances are formed in cultivated plants ; they do not form peculiar secretions, but merely store up some particular substance in excess. Nor shall we find the matter weakened if the elements con- cerned in nutrition be severally examined. Oxygen and hydrogen need not be here considered, as they are amply supplied by water. Attention, therefore, may be confined to carbonic acid, nitrogen, sulphur, phosphorus, and the inorganic ashes. 1. Carbon is doubtless the most important constituent; it forms half the substance of the dry plant, and eight times as much as the nitrogen ; the whole question therefore turns on the absorption of carbon. As in general the organic matter of the earth cannot supply the exigencies of the whole plant, so neither can it satisfy its demand of carbon. Sugar plantations receive no manure in general, or at least merely the ashes of the spent canes. An acre produces 7500 lbs. of cane, the expressed juice of which contains at least 700 lbs., and the fragments of cane 500 lbs. of carbon. There is there- fore an expenditure of 1200 lbs. of carbon per acre without any compensation. The Oil palms grow in sand destitute of humus. Thirty- three million poimds of carbon are produced annually on ground free from organic matter in this way alone. DR. SCHLEIDEN'S TIIKOKY 0¥ AGRICULTUUE. 39 But the most striking instance is that of Bananas. An acre yields 98,000 lbs. of fruit a-year, which contains about 17,000 lbs. of carbon. For twenty years tlie harvest is repeated without any manure, and the ground, so far from becoming poorer, is every year more rich in iiunuis, from the decay of the large juicy leaves. But it may, perhaps, be as well to give some instances nearer home. The following table, by Boussingault, of plants grown in pure quartzose sand or burnt clay, with distilled water, is exactly to our piu'pose : — B o a & o e c be Increase in Carbon. •o a» i3 >^ .ti ts O K O ■A Hed Clover- Seed . . . l,58G 0,806 0,095 0,571 0.114 |l58 percent.

The objection that carbon is necessary to supply the carbonic acid requisite for the early stages of vegetable growth, is fully answered by the fact that, if such were the case, it is amply supplied by the atmosphere to the water with which the plant is nourished, and tiiat germinating seeds succeed for a time quite as well in moist quartz sand or cotton as in vegetable soil. The only question which remains is, whether carbonic acid is really present in sufficient quantities to supply the demand. This, however, scarcely needs any answer, for by the process of decomposition and vital action the whole of the carbonic acid is returned to the atmosphere, so that it is a simple case of repeated circulation through plants, animals, and atmosphere ; one gene- ration gradually affording the material for another, even were there not other sources which we have no power of estimating. But to set the matter beyond all doubt, the following calcula- tion may be made : — According to Link, Schwartz, and others, an acre of water meadow produces 4400 lbs. of hay, which, when dry, contains 45 . 8 per cent, of carbon. The hay then yields 2000 lbs. of carbon, to which 1000 lbs. may be added for the other portion of the year and for the roots. To produce these 3000 lbs. of carbon, 10,980 lbs. of carbonic acid are requisite, which may be raised to 12,000 lbs., to compensate for the nightly expiration. Now, according to Schubler, an acre of so wretched a grass as Poa annua exhales in 120 days (too low a computation) of active vegetation 6,000,000 lbs. of water. To supply the exi- gencies of the plants then, it is only necessary for it to imbibe 3^ grains of carbonic acid with every pound of water. 2. Nitrogen comes next in order. If there are soluble sub- stances in the soil which could, if necessary, supply the requisite carbon, there are none to furnish the nitrogen. As soon, there- fore, as it was ascertained that plants receive their nitrogen in the form of ammonia, it was generally allowed that organic nitrogenous particles of the soil must first, by decomposition, form ammonia before they can be available for nutrition. The ques- tion, therefore, as to the origin of the nitrogen of plants, assumes quite a different shape from that of carbon. There is no doubt as to the form in which it enters, but whether they depend in greater or less degree on the ammonia contained in the organic matter of the soil, or whether in this respect also they are independent of the organic substances of the soil, is matter of inquiry. Now it is clear that the ammonia from the nitrogenous con- stituents of the soil is as available for vegetation as other am- monia, and that our domestic plants do not require a greater supply than in a state of nature. A water meadow which has DR. SCHLEIDEN'S THEORY OF AGRICULTURE. 41 never received anj' dunj? yields yearly 40-50 lbs. of nitrogen, while the best ploughed land yields only about 31 lbs. The plants for which most dung is used, as potatoes and turnips, are in fact proportionally the poorest in nitrogen. The vast Pampas of Buenos Ayres, since the introduction of horses and oxen, have yielded for their support almost incal- culable quantities of nitrogen, millions of pounds being annually carried off in the form of hides, horns, &.c. ; and yet there is no decrease in tiie produce of the country, which must have been the case had the plants depended upon the soil for the requisite ammonia. The Swiss Alps, the meadows of East Friesland and Holland, receive no organic nitrogenous matter, for the dung of the beasts whicii feed on them contributes always less than they have received. A horse, according to Boussingault, consumes in its food in 24 hours 78 -6 drams of nitrogen ; the excrement con- tains only 65 drams; 13' 5 drams are given off by perspiration in the form of ammonia. In the cow the nourishment in the same time contains 113*7 drams, the nitrogen in the excrement and milk amounts to 98 '4 drams, and that of the perspiration to 15 -2 drams. In other worils, the cow returns to the meadow for the 710 drams of nitrogenous organic matter which she con- sumes, only 614 7. JSevertheless, these alps and meadows con- tribute annually enormous quantities of nitrogenous matter in the shape of hay and cheese. This production of nitrogen must therefore be independent of the soil. Another proof appears as follows : — Since the manure is intended for the supply of several successive years, the content of nitrogen in the crop, as the decomposition proceeds, must year by year regularly rise or fall. It is, however, quite inde- pendent of the time which may have elapsed since the manure was applied, as appears from the following table taken from Boussingault : — Nitrogen per Acre, lb. Year 1. Potatoes 24,75 „ 2. Wheat 18,92 „ 3. Clover 45,21 „ 4. Wheat and stubble turnips 29,93 „ 5. Peas 52,63 „ 6. Rye 17,43 In two five-year courses, and one of six years, the ground re- ceived yearly, per acre, 21-90 lbs. of nitrogen in dung. The excess of nitrogen in the produce over that in the dung was yearly— 42 DR. SCULEIDEN'S THEORY OF AGRICULTURE. lb. ; lu the first 5 years' course . . . 5,06 In the second 5,15 In the 6 years' course . . . . 9,83 According to De Saussure, nitrogenous substances are per- fectly decayed in 88 days. But supposing the nitrogen supplied by the dung to be available for nutriment during the first year, yet after repeated ploughing eveiy trace must have disappeared, and there would be no supply but for that which is absorbed from the air. Yet in the foregoing table we have the pro- duction of 18-92 lbs. per acre in the second year, and 52*63 in the fifth. If, then, 40 or 50 lbs. can be absorbed from the atmosphere when no dung is present, it seems absurd to suppose that 18 lbs. cannot be absorbed for the wheat and rye. If we refer to the table at page 39, we shall see that the nitrogen was increased 37 per cent, in red clover grown in quartzose sand or burnt clay, with distilled water, in the course of 3 months only; while peas in 99 days gained 119 per cent., and wheat 5 per cent. In the last experiment, red clover trans- planted into tlie same soil gained in 2 months about 70 per cent. It remains only to inquire whether plants can derive sufficient ammonia from the air. As before, in the consideration of car- bon, it may be remarked that plants and animals are momentarily giving out an immense quantity by the act of decomposition, and though we find but little in the atmosphere and in variable quantities, it must be recollected how easily and quickly it is absorbed by every porous body and by water so as to be at once available for nutriment. There is tiien a constant circulation of this element as of cai'bon, and there are other sources, as volcanoes and thunder storms, in which the hydrogen and oxygen arising from the decomposition of water pass into nitrate of ammonia, and the combination of free hydrogen with the carbon of the atmosphere. Lastly, by a consideration similar to that which was made with respect to carbon, it appears that -j'^ of a grain of ammonia in every pound of water is sufficient for the exigen- cies of vegetation, and there is perhaps no spring water in the universe which contains so little. 3. The quantity of sulphur and phosphorus is so small that it is needless to enter into lengthened details. Peas, which yield 50 lbs. of nitrogen per acre, contain in tlie albumen 2 lbs. of sulphur and 1 of phosphorus. If tlie time of vegetation is spread over 120 days, and reckoning the height of the atmos- phere at 3000 feet, only -5-4-Vo-o-o- of a grain of sulphuretted hydro- gen and TrrFTiVo-o-o- of a grain of phosphuretted hydrogen per cubic foot are requisite. DR SCHLEIDEN'S THEORY OF AGKICULTUEE. 43 "We have still to consider those inorganic substances which remain in the ashes when a plant is burnt. It has been already seen that the inorganic or mineral con- stituents of the soil are of the most importance not only for plants in general, but for plants of husbandry. Tiiis is no new theory ; it was broached by De Saussure in the last century ; and even before Liebig reproduced it in a more perfect form, it had been acknowledged by Thaer and some other genial spirits. Notwith- standing all the great difficulties \\hich are involved in the study of the inorganic constituents of plants, their importance is un- questionable; and when we compare the analyses of their ashes, conducted on tlie same uniform plan, the result is incontestable that different plants are distinguished by the quantity and quality of their inorganic contents. Unfortunately such analyses have been confined principally to plants under cultivation. But with differences of outward form and modifications of cliemical action there must be great differences also of inorganic contents. We cannot indeed at present follow the intimate connexion between the process of vegetation and the inorganic constituents, yet the certainty of this connexion is beyond all doubt. Take what plant we may, we always find that witli a different content in organic constituents there is a difference in the quantity of inorganic matters. We may refer to Boussingault's table of comparison of the nitrogen and phosphoric acid in plants : from this it appears that the proi)ortion of phosphoric acid to nitrogen is tolerably constant ; yet the phosphoric acid is in no general necessary proportion to tlie nitrogen. It is very probable there- fore tliat pliosphoric acid does not contribute directly to the formation of the nitrogenous parts, for albumen, gluten, and legumin contain nearly the same quantity of phosphorus, viz., about 0-3 per cent., although the proportion of phosphoric acid to nitrogen in the plants which afford gluten, as wheat, maize, and oats, is as 1 : 2*9 ; in the albuminous i)lants (as hay, potatoes, mangel wurzel, stubble turnips, and Jerusalem artichokes), as 1"35 ; and in those which contain legumin (as clover, beans, peas, and kidney beans), as 1 : 4*6. It is self-evident tiiat the inorganic constituents of plants are received from the soil in solution with water. It remains only to inquire what inorganic constituents are most important for do- mestic plants. They require indeed in kind the same as wild plants, but the question as to quantity is verj- different. They yield in general nearly twice as mucli of inorganic ashes. Flint is mostly found in the walls of the cells in which it is deposited, and whicli it helps to strengthen ; and the same may be said of a portion of the lime, wiiich enters as a pectate into an insoluble combination with the gelatinous component of the cell 44 UR. SCHLEIDEN'S THEOKT OF AGRICULTURE. walls. We can form a notion of the content in silex from an examination of domestic plants, though silex is by no means characteristic of tliem, but rather of monocotyledons in general. 100 Parts of Silex.

The phosphates, as appears from a careful microscopic exam- ination of the ashes, are found principally in the contents of the cells, and the easily soluble alkaline salts are diffused in the liquid matter. If then it is the inorganic constituents especially which modify the chemical action of plants, it must be in great measure the pliosphates and alkalis, since this process takes place principally in the inside of the cells and their contained juices. The flint and lime contained in the cells must have a constant and direct proportion to the quantity of cells and the mass of the whole plant ; the pliosphates and alkalis on the contrary rise or fall with modifications of the chemical action. There are two circumstances especially in which wild vegeta- tion is distinguished from that of our cultivated fields. 1st. In wild plants the departing generation is again incorporated with the ground. All the inorganic matters whicli they received from the soil return to it, and in the most favourable form. In cultiAation, on the contrary, great quantities of inorganic matter, and that exclusively important for vegetation, are carried oflf with the plants themselves, and in consequence the soil must in a short time be exhausted if nothing be brought in in the shape of manure. 2ndly. Uncultivated ground becomes constantly richer in humus through the decay of the plants which it produced, and the more so because, in consequence of its never being disturbed, the decomposition of the humus is indefinitely prolonged, while cul- tivated land not only suffers from tlie removal of the crop, but what liumus it contains is continually subject to decomposition by the frequent exposure of a new surface to the atmosphere. It may besides be mentioned that in cultivation, as the ground is covered by a crop consisting of one plant only, the inorganic materials are far less fully worked up than where the especial exigencies of multitudes of plants of different natures are to be supplied at one and the same instant. There is, however, one more important circumstance to be mentioned before this part of the subject is closed, on which the dependence of agricultural plants on their soil actually rests. The geographical distribution of plants is determined by ^the con- DR. SCHLEIDEN S THEORY OF AGRICULTURE. 45 currence of all those conditions on which the success of any par- ticular species depends. In general the peculiar kinds under cultivation in any given locality depend on the geographical dis- tribution of the species. Every locality in the more anciently cultivated parts of the Old World has some prevailing kind of bread-corn, that, viz. which yields the greatest produce in that particular district. If a line be drawn from the o6th degree of North latitude through Asia, gradually approacliing the 60th degree passing through the Lake of Ladoga, and then almost to tlie 66th degree in Sweden — this line forms the southern limit of the first zone of cultivation. Part of the mountainous distiicts of Korway and Scotland belong to this zone. Korth of tliis line, as far as cultivation extends towards the Pole, Barley, in some one of its forms, is the peculiar bread-corn, and Rye is cultivated only in favourable situations. A second line runs through Asia almost coincident with the 51st degree, retiring in Russia and Germany a little below 50°, proceeding through Holland and through the north of England and Ireland. Between this and the former line Rye is the staple corn, mixed here and there in favourable localities with Wheat. Both these regions have besides a plant of a different order producing Hour, especially in the northern half of the Rye zone, viz., Buckw heat. In the south of England, the north of France, the middle of Germany to the Alps, the north of Turkey, the south of Russia, and from thence through Asia in a broad zone to Persia and Thibet, AVheat is the bread- corn, with Rye intermixed in rough mountainous districts. Finally, the whole circuit of the Mediterranean Sea produces Wheat and Maize almost in equal quantities. The environs of the Red Sea, the nortli coast of the Indian Ocean, and the north of India yield Wheat and Rice in pretty equal propor- tions ; and finally in the two Indian Peninsulas, China, and Japan, Rice is the exclusive staple. In all the northern districts the cereals are notoriously intro- duced plants which would vanish entirely in all parts of Europe at least, without cultivation. Their presence and their geogra- phical distribution in those countries affirm nothing more than that they have found there suitable conditions of climate. Even supposing them to be indigenous, the cessation of their cultiva- tion would cause them to disappear except from some very con- fined district. The distribution of plants does not depend alone on conditions of climate. We have in cultivation to provide cer- tain conditions which nature has not provided in the field of our exertions, w hile wild vegetation needs no such artificial help, since plants in nature do not grow where the conditions necessary for their existence are not present. 46 SPIK^A PHUNIFOLIA AND FORSITHIA VIRIDISSIMA "VVe stop here for the present with the intention of returning to the subject in a future number. We have shown what are the author's notions as to what manure will not do — we are next to see what it really is calculated to effect. IV. — On Spircea prunifolia Jiore plow and Forsytlda viridis- sima in the United States. By John Saul, Washington, D.C. (Communicated November 11, 1851.) Some idea of the beauty and condition of these plants in this country may perhaps be gleaned from the following observa- tions : — ■ Spircea prunifolia Jlore pleno. — When this plant first made its appearance in England, and in some parts of the continent of Europe, it was hailed as a great acquisition. It will be recol- lected that Mr. Fortune sent it from China to the Horticultural Society's Garden at Chiswick, and that Mr. Van Houtte had it from Dr. Van Siebold. It was let out fiom Ghent at a high price, and its sale I presume must have been extensive ; for it was soon scattered over England in all directions. Nevertheless, how few have been successful in cultivating it ! I have known parties in England who had fine plants which they never bloomed well ! Now, what were the causes of failure ? Let us ex- amine how such subjects had been managed, and we shall pro- bably discover something like a cause. The plants in England, if grown in pots, were probably placed in a tolerably shady situa- tion ; if planted in the open ground, a piece of well prepared soil and sheltered situation were chosen for them : under both these circumstances they grew well, and apparently matured their wood ; I say apparently, for Avhen blooming time came, we had green abortions, called flowers. Now, if we inquire into the nature of the native climate of this plant, we shall soon perceive the cause of so much disappointment with it in England. If I describe the climate of the Middle States of this country, I shall, I apprehend, very nearly represent its natural conditions; here this plant is perfectly hardy, enduring a very low temperature. The springs are warm, followed by intense sunnner heat, with bright light ; autumn is also bright and warm. Under these cir- cumstances the wond acquires a firmness and maturity whicli it never attains in England. In the latter country, when ripe, it has at best a greenish hue, very different from the brown rigid appearance which it acquires in America. Spring comes, and IN THE UNITED STATES. 47 with it a profusion of bloom of snowy wliiteness, precisely like the flowers of Ranunculus aconitifolius, but smaller ; it is in no way particular as to soil, but dry rather than moist earth appears to suit it best. From its success here, it is evident that in Eng- land it would require a well-drained soil and an open, airy situa- tion, where it would receive all the sun and light which the climate can give, so as to get the wood thoroughly and perfectly ripened by autumn : this secured, a good bloom is certain. For forcing, this plant is invaluable ; for this purpose speci- mens grown in pots should be placed in a sunny situation, in order to mature their wood well ; if this is not attended to, failure will ensue. I have observed in some of the forcing houses in this country, tiiat wlien the plants had been kept too warm, in too dark a house, or the atmosphere over moist, green flowers were the result, and in some instances no flowers at all. Now, if this will happen in a climate like that of the Middle States, wliere the wood had been well ripened, how much more likely is it to occur in England, where the wood is never half matured, and the plants in tiiat state transferred to a warm dark forcing-house, at a season when there is little sun ! There are few plants more de- serving of care or attention than this, whether employed in or- namenting the shrubbery in spring, or the conservatory and green-house at an early season. How very neces.sary it is that we should know the latitudes from whence plants come, in order to be able to treat them properly ! How frequently is every method but the right one tried ! — soil, situation, frequently too much heat. Had more of the beams of the sun been permitted, all would have been well. Forsythia riridissima. — The value and exquisite beauty of this plant are not, I fear, sufficiently known in England, where by many it is only considered a second rate subject. When Mr. Fortune introduced it to the Garden of the Horticultural Society from China, he spoke in high terms of its beauty, and I question much whether any thing more handsome can be found among all his introductions, not excepting even the lovely Weigela rosea. It has qualities aa Inch the latter does not possess, and which must ever render it one of the most Aaluable of hardy plants. From specimens which I had an opportunity of inspecting in England,* I entertained a doubtful opinion of its merits. What was my surprise last March, however, when I beheld a magnificent bush of it in the nursery of A. Saul and Co., Newburgh, New York, covered with myriads of its deep yellow blossoms ! The nursery in question is situated in the highlands of the Hudson, with that * Some persons may have been successful in cultivating it there, but no really fine plants ever came under my notice in that country. 48 SPIRAEA PRUNIFOLIA AND lORSYTIIIA VIKIDISflMA noble river flowing by their base, and open to a cold breeze from the north, especially in winter, during which time tiie constitu- tional hardiness of plants can be well tested. The soil in which it grows is a gravelly loam ; the plant is about 5 feet high, very bushy, and it appears to have been planted two or three years. During the summer of 1850 it made shoots from 3 to 4 feet long, which, though strong and gross, •were well ripened in the autumn The bright light and burning heat of an American sun consolidatethe wood as it elongates during summer. Autumn arrives, fully as warm as an English summer, and much drier. This perfects what remains of the ripening process, and enables the plant to endure the winter unprotected, through a degree of cold which has no parallel in Britain. About the middle of IMarch it commences opening its blooms, which had been thickly set over the wood of the previous year, and by the end of the same month it is one complete mass of deep yellow. Its season of flowering will of course depend on the latitude in which it is grown : here it commenced opening its blooms on the first ap- proach of fair weather, and while the snow still lay thickly on the ground. Compared with other early flowering plants, it was decidedly ahead of all of them. Even the early Pyrus (Cydo- nia) Japonica had scarcely commenced expanding its flowers when the Forsythia was in full beauty. In the 1st Vol. of the ' Gardener's Magazine of Botany,' p. 249, occurs the following passage : — " Unfortunately the flowers are too delicate in texture to bear exposure to rough w'ind, as they are readily bruised and soon show the effects of rough treatment ; but planted and trained against a wall, or in a very sheltered situation, it will be found a useful and excellent plant." So far is this from being correct, that I know of no plant whose blooms will bear an'equal amount of " rough treatment" uninjured. The subject of my remarks here was fuUj' three weeks in bloom, during which time it encountered one or two falls of snow and much wet weather, yet the blooms did not appear discoloured in the least up to the time they dropped off, and the ground was literally covered with them. The plant was in an open, exposed situation. In order to grow this plant well in England, we must examine the causes to which success is to be attributed in the case just cited. It was not soil ; for that in which the plant was placed was rather of a poor de- scription, and I observed other plants in the same nursery grow- ing vigorously in earth of the poorest kind. Bright light and intense heat are the conditions to which success was owing ; for the plants were luxuriant and happy, such as we might expect to have seen them in their Eastern home. In England, no doubt, the best situation for it would be against a soutli wall, where it would receive all the sunlight possible ; so circumstanced, it IN THE UNITED STATES, 49 would ripen its wood well and yield abundance of flowers in early spring-, or more probably in the mild climate of Eiig-land it would bloom like the Cydonia Japonica, Chimonanthus fragrans, the greater part of the winter. JPlanted out as a bush, an open, airy situation should be chosen, where it would receive the direct rays of the sun all day ; in all cases it should be guarrled against overmuch moisture at the root : let the soil in which it grows be ratlier dry than otherwise. In this way the wood would ripen well in autumn, and would be followed by an almndant bloom. The work from wliich I have already extracted considers it a very useful plant for winter and spring forcing, an opinion in which I entirely concur. In order to grow" this plant for winter blooming in the conser- vatory or green-house, take strong young plants in the spring ; shift them liberally, using any good compost ; stop the plant to cause it to break into several shoots — as it is rather inclined to throw one or two strong branches. As the plants progress in growth they should be shifted occasionally, and frequently stopped ; the best way of effecting this is, as soon as any shoots are ob- served to grow longer than the others, to pinch out the extreme points ; they will soon break freely : whereas if left till the wood becomes firm and then shortened, they take a longer time lo break, and they never do it so freely. When the plants have com- pleted their growth, let them be placed in an open, sunny situa- tion,— they cannot possibly be too much in the blaze of the sun : — • here they should remain until autumn arrives, when tliey may be plunged in any convenient situation. As the plants are re- quired to bloom they may be introduced into tlie forcinij-house, or what in my opinion is better and quite sufficient for the pur- pose, a warm green house, placing them in the most sunny part of it. In a house of this description the blooms would come deeper in colour ; it is well known how pale and washy such colours are out of the confined atmosphere of a forcing-house. Whether used for the latter purpose, or grown in the open border, as I have already stated, I consider this plant one of the most valuable of Mr, Fortune's introductions. The Weigela, though extremely beautiful, blooms at a season when many other things are in flower, whilst the Forsythia blossoms when every stray floret is welcome. Note. — The Weatlier Register at Shanghae given in the folio-wing pages will materially elucidate the question of -what climate does for these t-wo plants. VOL. VII. 50 A REGISTER OF THE WEATHER AT SHANGHAI: V. — A Register of the Weather at Shanghae for Nine Months of the Years 1850-51. The large number of plants now in our gardens from those Chinese provinces the climate of which may be practically regarded as illustrated by that of Shanghae, has suggested the propriety of printing, from the colmnns of the North China Herald newspaper, a pretty complete record of the weather there for two years from tlie beginning of November to the end of July. Hereafter, if the paper should continue to reach England, the three remaining months may also be given, with such remarks as the facts mentioned in the Register may seem to call for. In the mean while it is sufficient to point out the fact that the Camellia, the Chinese Azalea, the Tea-plant, the Cryptomeria, and numerous other shrubs, find themselves at home in the cli- mate here described.

The beans are healthy ; in many places the pods have attained a length of three inches, containing seeds two lines in their greatest diameter. The peasants were observed yesterday for the first time scattering cotton seed among the wheat, to be ready to take the place of the latter crop when cut down. The average temperature during the past week has been 57-4° ; during the corresponding week of 1850 it attained an average of 65-3° — an excess of heat over the present season of no less than 7 9°.

In numerous fields the crop of beans has been ruthlessly pulled up by the roots and either dug or ploughed into the ground for manure, grown apparently for no other purpose. Those fields intended for the future growth of paddy have been irrigated by the numerous chain pump machines in the con- struction of wliich the Chinese display so much ingeimity. During the last few days the peasants have been busy in treading with their feet and by means ol' buffaloes the irrigated fields, and in one or two parts have sown that portion of the grain intended for subsequent transplantation.

At no season of the year is there greater cause to admire the Chinese husbandry than at this, the time for sowing cotton. The art with which the four-pronged implement of agriculture, half pitchfork, half hoe, is wielded, so as to act as both spade and rake, calls down our admiration. The neatness with which the beds are pre- pared, and the seed sown and trodden down, is one of the circumstances in which has originated the title to an almost fabulous superiority of the natives of this empire over Europeans in the cultivation of the soil. Some of the cotton sown only a few days since is already appearing above ground. The paddy intended for transplantation is now a couple of inches high. In some fields the bearded wheat is nearly ready for cutting, and the ears of the unbearded variety are improving in size.

It is very extraordinary to observe the carelessness with which this process is con- ducted, and the little anxiety manifested by the peasants to keep their grain clean.

( 69 ) VI. — On the Climate and Vegetation of the Temperate and Cold Regions of East Nepal and the Sikkim Himalaya 3Iountains. By J. D. Hooker, M.D., F.E.S. The following notes were collected, and have here been thrown together, with the view of facilitating the cultivation of Hima- layan plants, and of those of Sikkim and the adjacent mountains of Nepal in particular, by supplying accurate data obtained on the spot, relative to the various conditions of soil and exposure, the degrees of temperature and amount of humidity under which they flourish in their native country. As the genus Rhododendron is the most prominent of these plants, and that about which inquiries are constantly directed to me, I shall commence wdth a description of it, prefacing this with some observations, wliich are called forth by a visit to several nurseries where many species are cultivated with more or less success. The Sikkim species of Rhododendron have now all been de- scribed, as far as tiiey are known, and with few exceptions figured, in a manner that will ensure the recognition of our seedlings when they blossom ; but it must not be expected that the flowers, so impatiently looked for, will in all or perhaps in most cases equal, in number and size, those of the dra^nngs made on the spot, which were in many instances from the choicest bouquets that could be procured over a large extent of country. Unexampled success has attended cultivators in the germina- tion of the seeds. Seedlings liave been raised in quantities ; but whereas in some cases the young plants have, with few exceptions, been all reared, in others the whole crop has been lost tlirough injudicious treatment. The different kinds are at present kept together and treated alike ; there is no discrimination exercised in their culture ; the same amount of light and heat as is given to the natives of 6000 and 7000 feet elevation, wliich are in full leaf throughout the year, is also given to those from ] 5,000 feet, whose vegetative organs are in activity for only five or six months of the twelve. This course will eventually prove preju- dicial, for it is not possible that the alpine kinds can long endure the excitement of perennial heat and moisture. Variatioji. — There is a prevailing disposition to limit the species of this genus by characters presented in the seedling plants, and to argue, from my inability to pronounce arbitrarily on the same in our greenhouses, the probability of there being fewer or more species than of names received with the seeds. In some cases an undue value is given to these names. Slight varia- 70 CLIMATE AND VEGETATION OF tions in the strength of the stem, colour, texture, and hairiness of the leaf, are regarded as certainly indicating specific differences ; whilst other kinds are considered as the same, because un- distinguishable in their present infant condition. Some of the latter certainly resemble one another in foliage, even when full grown, but are nevertheless totally distinct in flower and in fruit. I may instance R. cinnabarinum, R. camelliajtorum, and R. 3Iaddeni, as one case in point ; R. campylocarjrum and R. Thomsoni as another ; R. campamdatum and R. fulgens as a third instance of species being often so alike in the leaf, as generally to puzzle me when I had nothing else to judge by ; and yet there is in the two former cases little affinity between them. My attention was drawn to this point throughout a resi- dence of many consecutive months (including the flowering and .fruiting seasons of the Rhododendron) at elevations varying from 8000 to 16,000 feet. It is especially between 10,000 and 14,000 feet that the genus prevails ; several species comprising three-quarters of the bulk of the vegetation above the forest- region (12,000 feet). There Rhododendron wood supplies the native with fuel, and, from its tough nature and property of being easily worked, witii many domestic vitensils, poles for his tent, stools, saddle, bowl and spoon ; the bark is used as that of the birch is in arctic regions, and the leaves serve as plates and wrappers for butter, curd, and cheese. It is the traveller's con- stant companion throughout every day's march ; on tlie right hand and on the left of the devious paths, the old trees and bushes are seen breast high or branching over head, whilst the seedlings cover every mossy bank. At 13,000 feet the flanks of the snowy mountains glow .with the blood-red blossoms of R. fulgens, whilst the beauty of R. campanulatum and the great elegance and delicacy of the white bells of R. camjjylocarpum excite the more admiration from their being found in such regions of fog and rain. Yet with all these advantages of position, and that of an intimate knowledge of the species, I was constantly at a loss to distinguish to which species the seedling plants belonged, especially when they grew intermixed, or to recognize others when distant from their parents. Is ot only does the very variable nature of the foliage render it exceedingly difficult to recognize even the best known kinds by tliese organs, but the species themselves run into races, stirpes, or constant varieties, assuming under certain circum- stances characters inherited by the seedlings. This is habitually the case with those that have considerable ranges in elevation ; they alter their habit materially (as willows do in our own country), and there is more apparent difference between the robust, hardy, rusty-leaved, dark-coloured seedlings from an EAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAINS. 71 alpine locality, and the young plants of the same species from wooded regions lo^ye^ down, than between some widely distinct species. I have hereby been led into much error in my illus- trated work on Sikkim Rhododendrons, which I shall endeavour to remedy in the present essay. Hybridization in a Native State, — It has been insisted that many of the so-called species of this genus are naturally-produced hybrids. This is by no means clear to me, though I am far from denying its possibility, and I am aware of the many obvious facilities for such a process : it shares the plausibility of all hy- potheses against which negative proof only can be brought to bear. A gardener's opinion is in such cases of value, as he can best appreciate the power of an agent he employs himself with great effect, and to which the attention of botanists is being drawn through the pages of this Journal especially. Con- sidering, however, the consequences which have attended the process of hybridizing Rhododendrons in our gardens, it appears to me that were such an operation actively pursued by nature, or tardily throughout a series of years, in the Rhododen- dron region of the Himalaya, the species would be in the con- dition of Salix, Ruhiis, Rosa, Mentha, and many other familiar examples of hopelessly entangled assemblages of species. Where the Rhododendron "scrub" prevails, it is impossible for any but very strong growing plants to establish a footing ; a mule would have little chance of a flourishing existence anti numerous offspring'in so dense a mass ; but the prevalence of land and snow-slips often lays bare broad tracts of land, \\hich are for years but scantily clothed with vegetation. From the constant local changes of surface that hence ensue, there is no want of opportunity and space for hybrids to establish themselves. Be- lieving it probable that this genus has survived slow but gi'eat changes in the physical geography and climate of the countrj'^, especially with relation to the snow -level, I cannot but conclude that varieties, perhaps permanent ones, may have been induced, which are now regarded as species ; and this has prompted me to unite some plants from very different elevations which, though varying much, present no well-marked specific characters. Such are R. eltsagnoides, R. salignum, and R. obovatum. All these I include under Wallich's R. lepidotum, to which a range in ele- vation of upwards of 7000 feet is consequently given, but I can- not trace the influence of hybridization in itself or any allied species. It is accompanied by twenty congeners in its ascent from 7000 to 15.000 feet, but except that its flowers varj' from yellow to a dirty purple, at various heights, neither it nor they present any characters that can be attributed to hybridization. ^.fulgens is the most suspicious- looking plant in this respect, 72 CLIMATE AND VEGETATION OV liaving the leaves of R. campanulatum, and capitula and flowers of a scarlet variety of R. arboreum ; but considering how variable R. campanulutum is in colour, and that it assumes a denser capi- tuhnn in its variety ceruginosurn (which I published as a species), I sliould be more inclined to rank. R. fulgens as a permanent variety of that species tlian as a mule between it and a plant with a totally dissimilar leaf, which is comparatively tender, and which grows 4000 feet lower down. The principle of hybridization is a dangerous one to admit heedlessly in these cases, and should only be resorted to as a forlorn hope, when every other attempt to account for the Protean habits of an assemblage of species has failed : such I cannot consider to be the case with the Sikkim Rhododendrons ; and though I do not abandon the idea in theory, I shall not adopt it in this emergency. Epiphytical Habits of some Species. — Much undue import- ance has been given to the fact of some kinds growing habitu- ally epiphytically (R. Dalhousice, R. camelliccjiorum^ R. pendu- lum^, and it has been supposed that much difficulty must attend their cultivation. Having occasionally seen all these species growing on rocks, and the two latter sometimes becoming erect, and that always in exposed but very moist localities, I have been induced to attribute their predilection for tlie branches of trees to their weak habit and want of light elsewhere. Being plants of the forest region, and unable to contend against the vigorous undergrowth that prevails there, the offspring of sucli seeds as fall on the ground are choked, whilst the perennially humid atmosphere supports such as sprout on the mossy limbs of trees, where they receive the stimulus of light. R. Dalhousice, for instance, which is never found on the ground in the woods of Darjiling, grows in thousands on the clay and mould banks of the roads which are cut through the forest, the young plants coming up in profusion as soon as the cuttings are made : these, however, seldom attain any size, from the too great exposure of the soil, which in the dry season rapidly parches during a short day's heat. In Dr. Campbell's garden at Darjiling there is a perpendicular bank, 15 feet high, exposed to the west, and partly sheltered from the south-west by a house. R. Dalhousice has annually appeared on this, the seeds being imported by winds or birds from the neighbouring forest. The seedlings, however, perished till within the last two years, since which time abundance of Lyco- jwdiuin clavatum and a Selaginella, with Marclinntia, retain so constant a supply of moisture that the plants now flourish and flower in perfection. Though not equal to the herbaceous, the number of small shrubby forest plants that grow on the trees in these damp regions is very great, especially the orchideous. Those that do so most habitually are species of Vaccinium EAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAINS. 73 (serpens and others). These are all provided with soft woody swellings on the root, of all sizes, from that of a nut to the thick- ness of a man's thigh, which, though structurallj^ the same as other parts of the root, serve as reservoirs for a great quantity of fluid destined to nourish the plant in the drier season of the year. These plants never grow on the ground, properly speaking, but often on exposed rocks, where the use of these tubers is more evi- dent, and it is a part of their economy to be so provided. The Rhododendrons have never such organs, and there is no difference between the root of a specimen grown on the ground and one from a mossy tree-trunk. Such species as are habitually epiphytical re- quire a lighter soil, with plenty of moss, and a very damp, humid, equable temperature ; and will, I am sure, present no insuperable obstacles to the cultivator. Soil. — There is in this respect little variety throughout Sikkim, and, as far as vegetation is concerned, it may be divided into vege- table mould and stiff clay — each, as they usually occur, remark- ably characteristic in composition of such soils. The clay is uniformly of great tenacity, and is, I believe, wholly due to the effect of the atmosphere on crumbling gneiss and other rocks. It is tenacious, seldom friable, and sometimes accumulated in beds 14 feet thick, although more generally of only about 2 feet. In certain localities, beds or narrow seams of purer felspathic clay on vegetable matter occur in it, probably wholly due to local causes. An analysis of that near Darjiling gives about 30 percent, of alumina, the rest silica, and a fraction of oxide of iron. Lime is wholly unknown as a constituent of the soil, and only occasionally seen as a stalactitic deposit from a few springs. The vegetation has always good drainage, from the broken nature of the subjacent highly-inclined stratified rocks : with the Rhododendrons of the second zone this is especially the case, and they thrive luxuriantly on the soil overlying old moraines. A layer of vegetable earth almost invariably covers the clay for the depth of 3 to 12 or 14 inches. It is a very rich black mould, held in its position on the slopes of the hills by the dense vegetation, and accumulated by the banks of small streams to a depth at times of 3 and 4 feet. R. arhoreum is one of the few species that seem to avoid this soil, but, I think, in appearance only — that species loving exposure, and therefore occupjang a comparatively poor dry soil, over which other things do not extend. I have seen R. arboreitm and barbatiim growing on the margins of pools of water, in what is almost bog earth ; but pools and bogs are rare in Sikkim, and of very local occur- rence. The following is an analysis of an average specimen of 74 CLIMATE AND VEGETATION OF the surface-soil of Darjiling-, made for me by my friend C. J. Miiller, Esq., of that place : — A.— Dry Earth. Anhydrous 83'84 Water 16-16 100-0 B. — Anhydrous Earth. Humic acid 3*89 Humine . . ■ 4-()l Uudecomposed vegetable matter . . . 20-98 Peroxide of iron and manganese . . . 7-05 Alumina 8-93 Silicious matter, insoluble in dilute hydro- chloric acid 54-52 Traces of soda and muriatic acid ... • • 100-0 C. — Soluble in water, gr. 1'26, consisting of soda, muriatic acid, organic matter, and silica. The soil from which this example was taken was 12 inches deep ; it abounded to the eye in vegetable matter, and was sili- cious to the touch. There were no traces of phospliates or of animal matter, and doubtful traces of lime and potasli. The subsoil of clay gave only 5*7 per cent, of water, and 5-55 of or- ganic matter. The above analysis was conducted during the rainy month of September, and tlie sample is an average one of the surface-soil at 6000 to 10,000 feet. There is, I think, little difference anywhere in the soils at this elevation, except where the rock is remarkably micaceous, or where veins of felspatliic granite, by their decomposition, give rise to small beds of kaolin. At elevations above 10,000 feet, the rocks are generally much harder, the gneisses and schists are baked by metamor- phic action, and more granitic rocks prevailing, a lighter and more sandy soil is met with. Towards the southern parts of Sikkim, the copious rains wash away at once the scanty annual deposit of humus at these great elevations : there is consequently no sward or peat ; the plants, shrubby and herbaceous, growing out of a generally naked soil in tufts. In the northern parts, again, there is a considerable accumulation ; and at equal and greater elevations a sward of CijperacecB and Graminece are found, nourishing a tolerably rich Flora. Further north still, in the Tibetan climates, at 15,000 to 17,000 feet, the climate is too dry for anything but an arid Flora, except along the borders of streams. Generally speaking. I conclude that a rich light vegetable EAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAINS. 75 mould of loam and peat, with good drainage, are necessary for the shrubby plants of these regions. On the Species. — Since the preparation of the several parts of the illustrated work on the Sikkim Rhododendrons, my opinions, which were then far from fixed as to the limits of some of the species, have changed, with the many additions to the localities, &c., I have collected. When the first part was publislied, I had only seen single specimens of some of the species figured ; and without books of reference of any kind, I was unable to deter- mine their names ; the specimens and drawings sent diflTered so widely from cultivated individuals, and from the indifferent herbarium specimens attainable, that they were pronounced new, and published accordingly. The results of a careful study of all my species and specimens are, that of those figured in the first parf, R. Campbellice does not differ from R. aThoreum^ R. lanci- f'olium from R. barbatum, R. Wallichii from R, campanulatum, and R. Roylei from R. cinnabar inutn. In the second part a synoptical view of all the Indian species is given, in which some of these errors are indicated, and the species are thrown into groups defined by characters I still think natural and constant. In this and in the concluding (third) part 22 more Rhododendrons are figured as species, several of which were regarded by myself as well-marked forms or varieties only, and as such worth figuring, but which were published with the provisional specific names I attached to them. To these I shall allude liereafter. Lastly, I have gone over the Bhotan collections of Mr. Griffith, and identified all his 14 species with my own, except the one figured by Dr. Wight as R. grande. Of this I find no specimen in the set of Griffith's plants given to Sir W. Hooker, except it be the R. Hodgsoni, which I can hardly re- concile with the plate and description in Dr. Wight's Icones. Dr. Wight's R. Griffithii, on the other hand, 1 find to be founded on a very starved state of R. Aucklandii, a name which I waive. Bhotan borders upon Sikkim to the eastward, and presents the same characters of humidity in that western part (wiience Mr. Griffith's specimens wei'e procured) as Sikkim does. Its lower and outer ranges of liills, however, being drier (from reasons hereafter to be explained), it does not appear to be so rich in Rhododendrons, and hence probably no peculiar species are found; for to the eastward of Bhotan again, in the " Durrung" country, other species have been discovered by Mr. Bootli. I shall now give a list of tlie 27 Sikkim species known to me, arranged in natural groups, with such brief characters as are ne- cessary for determining them when they shall flower. An account of the geographical features of Sikkim will follow, and a division 76 CLIMATE AND VEGETATION OK of tlie country into zones, each inhabited by a different vegetation of Rhododendrons and other phmts. vSome more general descrip- tion of the species, with remarks on their appearance, habits, and relations to soil, climate, &c., will naturally be brought in there ; and I shall conclude with a raliier minute account of the climate, temperature, &c., of tiie tliree zones of the Himalaya, which may be termed Temperate, Alpine, and Arctic, and wliich are best defined by the limits attained by ConifercB and Rhododendrons.

If from a consideration of the species themselves we turn to that of the country they inhabit, it will be found that a great part of it is characterized by perennial humidity^, which is exces- sive during the summer months. It will be seen, also, that the degree of humidity varies in different parts of the country, and that the rain-fall is unequally distributed ; also that elevation is to a great degree a relative term, equal altitudes having different climates in various parts of Sikkim, with a dissimilar vegetation. To explain these points, it is necessary to give some account of the natural features of the Sikkim Himalaya Mountains, which seem to be little known, or generally misunderstood by those who have sought information respecting the management of Ehodo- dendrons, through the various horticultural periodicals. Except these points are clearly understood, it will be impossible to appreciate the conditions under whicli the species grow. Sikkim is included in a section of the Himalaya Mountains about sixty miles broad from east to west, where it is bounded respectively by the mountain states of Nepal and Bhotan. Its southern limits are easily defined, for the mountains rise rather abruptly from the plains of Bengal, as spurs of 6000 to 10,00Q feet high, densely clothed with forest to their summits. The northern and north-eastern frontier of Sikkim is beyond the reo^ion of Rhododendrons, and is not a natural but a political line, drawn between itself and Tibet. Sikkim is nearly due north of Calcutta, and only 400 miles from tiie sea at the Bay of Bengal ; its latitude being 26" 40' to 28" N., and longitude 88° to 89" E. The greater part of the country between Sikkim and the sea is a dead level, occupied by the delta of the Ganges and Burrampooter, above which the slope is so gradual to the base of the mountains, that the surface of the plain from which the Himalayas imme^v diately rise is only 300 feet above the sea. The most obvious effect of this position is, that the prevailing southerly wind reaches the first ranges of hills loaded with vapour. The same current, when deflected easterly to Bhotan, or westerly to Nepal and the north-west Himalaya, is intercepted and drained of much moisture, by the Khassya and Garrow Mountains (soutii of Assam and the Burrampooter) in the former case, and the Rajmahal hills EAST NEPAL AND THE 8IKKIM HIMALAYA MOUNTAINS. 83 (south of the Ganges) in the latter. Sikkim is hence the dampest region of the whole Himalaya. Viewed from a distance on the plains of India, Sikkim pre- sents the appearance — common to all mountainous countries — of consecutive parallel (wooded) ridges, running east and west, backed by a beautiful line of snowy peaks, with occasional breaks in the foremost ranges, throuoh which the rivers debouch. Any view of the Himalaya, especially at a sufficient distance for the distant snowy peaks to be seen overtopping the outer ridges, is very rare, from the constant deposition of vapours over the forest-clad ranges during the greater part of the year, and the haziness of the dry atmosphere of the plains in tlie winter months. At the end of the rains, when the S.E. monsoon has ceased to blow with constancy, views are obtained, sometimes from a distance of nearly 200 miles. The angle subtended by the giant peaks is so low (not a degree) that they appear like white specks very low on the horizon, tipping tlie black lower and outer wooded ranges, which always rest on a belt of haze, and from the density, probably, of the lower strata of atmos- phere, are never seen to rest on the visible horizon. The remark- able lowness on the horizon of the whole stupendous mass is always a disappointing feature to the new comer, who expects to see dazzling peaks towering in the air. Approaching nearer, the snowy mountains sink behind the wooded ones long before tlie latter have assumed gigantic proportions, and when tliey increase in size, they appear a sombre, lurid grey -green mass of vegetation, with no brightness or variation of colour. There is no break in this forest caused by rock, precipice, or cultivation ; some spurs project nearer, and some valleys appear to retire further into the heart of the first great cliain that shuts out all the country beyond. No pines whatever are seen on the outer range of Sikkim, both soil and climate being far too damp in the rainy season ; nor are the colours of the foliage so varied and bright as tlie more per- ennially humid forests of tropical shores, from the want of any abundance of such palms as Caryota, tall Arecce, and of Arto- carpi, or of orange-groves. As it is not my purpose to discuss here the tropical, or lower zone of Sikkim, I shall at once transport the reader to the north side of the first range of mountains. From here it will be seen that the appearance of parallel ridges is due to the inosculating spurs of long tortuous ranges that run north and south through- out the whole length of Sikkim, dividing deep wooded valleys, which form the beds of large rivers. The snowy peaks still look like a long east and west range of mountains, at an average distance of 30 or 40 miles from the outer range. Advancing into the country, this appearance proves equally deceptive, and the range of snow G 2 84 EAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAINS. is resolved into isolated [)eaks, situated on the meridional ranges, at distances varying from 30 to 80 miles from the observer ; their snowed spurs, projecting east and west, cross one another, and being uniformly white, and all brought by perspective into one line, they appear to connect all the peaks into one grand un- broken range of snow. The rivers, instead of having their sources in the snowy mountains, all rise far beyond them ; many of their sources are upwards of 100 miles in a straiglit line from the plains, in a very curious country, loftier by far in mean ele- vation than the meridional ridges which run south from it, and though so lofty, comparatively unsnowed. This rearward moun- tain region is Tibet, and into it all the Sikkim, Nepal, and Bhotan rivers lead, up to a watershed whose discharge to the northward is into the Yarou-Tsampu river, which becomes the Burrampooter of Assam. Tibet is a very arid mountain mass, the southerly wind being exhausted of vapour by these long ridges long before reaching it. The maximum range in latitude and elevation of the Himalayan vegetation is determined very much by the length of the rivers, which, rising in Tibet as small streams, increase in size as they receive the drainage from the snowed parts of the ridges that bound them in their courses. Their banks, between 8000 and 14,000 feet, are generally clothed witli Rhodo- dendrons, sometimes to the almost total exclusion of other woody vegetation, especially near the snowed mountains — a cool tem- perature and great humidity being tlie most favourable conditions for the luxuriant gi'owth of this genus. The source of this humidity is the southerly or sea wind, which blows steadily from May till October in Sikkim, and pre- vails throughout the rest of the year, if not as the monsoon pro- perly so called, as a current from the moist atmosphere over the Gangetic delta. This ruslies north to the rarefied regions of Sikkim, up the great valleys, and does not appear materially disturbed by the north-west wind, which blows during the after- noon of the Avinter months over the plains, and along the flanks of the outer range, and is a dry surface current, due to the diurnal heating of tiie soil. When it is considered that this wind, after passing lofty mountains on the outer range, has to traverse 80 or 100 miles of alps before it has watered all the Rhododendron region, it will be evident that its moisture must be expended before it reaches Tibet. Let the accompanying woodcut represent two of these long meridional ridges, from the watershed to the plains of India, following in this instance the course of the Teesta river, from its source at 19,000 feet to where it debouches from the Hima- laya at 300.

A deep valley is interposed between these two ridges, with a feeder of the Teesta in it, which runs south from Kinchin, and turning west enters the Teesta at R. The position of the bed of the Teesta river is indicated by a dotted line from its source at T to the plains at S ; of Darjiling, on the north flank of the outer range, by D ; of the first point where perpetual snow is met with, by P ; and of the first indications of a Tibetan climate by C. A warm current of air, loaded ^nth vapour, will deposit the buliv of its moisture on the ridge (8000 feet) D. Passing on, little \^ill be precipitated on E, whose elevation is the same as that of D, but much at F (10,000 feet), where the current being further cooled has less capacity for holding vapour than it had at D, and is ftirther exhausted. "When it ascends to P (15,000 feet) it is sufficiently cooled to deposit snow in the winter and spring months, more of which falling than can be melted during the summer, it becomes perennial. At K (20,000 feet) ver}- little falls, and it is doubtful if the southerly current ever reaches the prodigiously elevated isolated summit of Kinchinjunga (28,178 feet) ;* but all that does, is evaporated or retained as snow. The amount of surface above 20,000 feet is, however, too limited and broken into isolated peaks to drain the already nearly exhausted wind current, whose condensed vapours roll along in fog beyond K, are dissipated during the day over the arid mountains of Tibet, and deposited at night on the cooled surface of the earth. Other phenomena of no less importance than the distribution of vapour, and more or less depending on it, are the duration and amount of solar and terrestrial radiation. Towards S the sun is rarely seen during the rainy season, as well from the con- stant presence of nimbi aloft, as of fog on the surface of the ground. An absence of both light and heat is the result in the parallel of K ; and at C low fogs prevail at the same season, but do not intercept either the same amount of light or heat ; whilst at T there is much sunshine and bright light. During the night, again, there is no terrestrial radiation between S and P ; the rain either continues to pour — in some months with increased violence — or the saturated atmosphere is con- * I believe that the utmost elevation the S.E. monsoon attains is 23,000 feet, and that only where the whole mass of land is immensely elevated.

EAST NEPAL AND THE SIKKI.M HIMALAYA MOUNTAINS. 87 densed into a thick white mist, which hangs over the redundant vegetation. A brigiit starlight night is ahnost unknown in the summer months at GOOO to 10,000 feet, but is frequent in December and January, and at intervals between October and May, when, however, vegetation is little affected by the cold of nocturnal radiation. In the regions north of K starlight nights are more frequent, and the cold produced by radiation is, at 14,000 feet, often severe towards the end of the rains in Sep- tember. Still the amount of clear w eather during the night is small ; the fog clears off for an hour or two at sunset as the wind falls, but the cold north returning current chills the air again soon after, and rolling masses of vapour are hence flying over- head or sweeping the surface of the earth throughout the summer nights. In the Tibetan regions, again, bright nights and even sharp frost prevail throughout the warmest months. Referring again to the cut, it must be borne in mind that neither of the two meridional ridges runs in a straight line, but that they wand or zigzag like all mountain ranges ; and that spurs from each ridge are given off" from either flank alternately, and that the head of a spur on one side answers to the source of a river (i.e., the head of a valley) on the other. These rivers ai-e feeders of the main stream, the Teesta, and run at more or less of an angle to the latter. The spurs from the east flank of one ridge cross, at their ends, those from the west flank of another ; and thus transverse valleys are formed, presenting many modifications of climate with regard to exposure, temperature, and humidity. The roads from the plains of India to the watershed in Tibet always cross these lateral spurs. The main ridge is too winding and rugged, and too lofty for habitation throughout the greater part of its length. The river channel is always very winding, un- healthy for the greater part of the year below 4000 feet, and often narrow, gorge-like, and rocky. Villages are always placed above the unhealthy regions, on the lateral spurs, which the traveller keeps crossing throughout every day's march ; for these spurs give off lesser ones, and these again others of a third degree, whence the country is cut up into as many spurs, ridges, and ranges, as there are rills, streams, and rivers on the moun- tains. Though the direction of the main atmospheric current is to the north, it is seldom in reality felt to be so, except theobservef is on the very exposed mountain tops, or watches the motions of the upper strata of atmosphere. The lower currents of air rush up botli the main and lateral valleys, throughout the day ; and from the sinuosities in the beds of the rivers, and generally trans- verse directions of their fieeders, the current often becomes an east or west one. In the branch valleys draining to the north 88 CLIMATE AND VEGETATION OF the wind still ascends ; it is, in short, an ascending warm moist current, whatever course be pursued by the valleys it follows. The sides of each valley are iience equally supplied with moisture, though local circumstances render the soil on one or the other flank more or less humid, and favourable to a luxuriant vegetation : such ditferencesare a drier soil on the north side, with a too free exposure to the sun at low elevations, where its rays, however transient, rapidly dry the groimd, and where the rains, though very heavy, are of sliorter duration, and owing to the capacity of the heated air for retaining moisture day fogs are comparatively rare. In the northern parts of Sikkim, again, some of the lateral valleys are so placed that the moist wind strikes the side facing the south and keeps it very humid, whilst the returning cold current from the neighbouring Tibetan mountains imjjinges against the side facing the north, which is hence nearly bare of vegetation. An infinite number of local peculiarities will suggest themselves to any one conversant with physical geography, as causing unequal local distribution of light, heat, and moisture in the different valleys of so irregular a country — the amount of slope, and its power of retaining moisture and soil ; the composition and hardness of the rocks ; their dip and strike ; the protection of some valleys by lofty snowed ridges, and the free southern exposures of others at great elevations. One other peculiarity deserves especial attention, which is, the position of the great masses of perpetual snow. A reference to the woodcut will show that the same circumstances which affect the distribution of moisture and vegetation, determine the posi- tion, amount, and duration of the snow. The principal fall will occur, as before sliown, where the meridional range first attains a sufficiently y^reat elevation, and the air becomes consequently cooled below 32° ; this is at a little above 14,000 feet, sporadic falls occurring even in summer at that elevation : this snow, however, melts immediately, as do the copious winter falls in the summer months. As the depth of rain-fall diminishes in advancing north to the higher parts of tiie meridional ranges, so does the snow-fall. Its permanence, again, depends on — 1. the depth of the accumulation ; 2. the mean temperature of the spot; .3. the melting power of the sun's rays ; 4. the prevalence and strength of evaporating winds. Now at 14,000 feet, though the accumulation is immense, the amount melted by the sun's rays is trifling, and there are no evaporating winds ; but the mean temperature is so high, and tlie corroding powers of the rain (which falls abundantly throughout summer) and of the warm and humid ascending currents are so great, that the snow is not perennial. At 15,000 feet, again, it becomes perennial, and its permanence at this low elevation (at P) is much favoured EAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAINS, 89 by the accumulation and detention of fogs over the rank vegeta- tion which prevails from 8 nearly to P ; and by the lofty moun- tains of K, which shield it from the returning dry currents from the north. In proceeding north all the circumstances that tend to the dispersion of the snow increase, whilst the fall diminishes. At P the deposition is enormous, and the snow-line low — 15,000 feet ; whilst at T little falls, and the limit of perpetual snow is 19,000 and 20,000 feet. Hence the anomaly, that the snow-line ascends in advancing north to tlie coldest Himalayan regions. The position of the greatest peaks and of the greatest mass of perpetual snow being generally assumed as that of the ridge or watershed, travellers, arguing from single mountains alone, on the meridional ridges, have at one time supported, and at another denied, the assertion, that the snow lies longer and deeper on the north than on the south flank of the Himalaya ridge. The great accumulation of snow at 15,000 feet, in the parallel of P, exercises a decided influence on the vegetation. The alpine Rhododendrons R. setosum and R. aiithopogon hardly reach 14,000 feet, sometimes not 13,000 feet, in the broad valleys and round-headed spurs of the flanks of Kinchinjunga ; whilst the same species ascend to 16,000, and one to 18,000 feet, at T. Beyond the latter point, again, the great aridity of the climate prevents their growth, and in Tibet there are generally none even as low as 12,000 and 14,000 feet. Glaciers, again, descend to 13,000 feet in the tortuous gorges which immediately debouche from the snows of Kinchinjunga, but no plants grow on the debris they carry down, nor is there any sward of grass or herbage at their base, the wliole surrounding atmosphere being chilled by enormous accumulations of snow, and the summer sun rarely warming the soil. At T, again, the glaciers do not descend below 16,000 feet, but a gi-een sward of vegetation creeps up to their bases, dwarf Rhododendrons cover the moraines, and herbs grow on the patches of earth they carry down, which are thawed by the more frequent sunshine, and by the radiation of heat from the unsnowed flanks of the valleys down which these icy streams pour. Looking eastward or westward on the map of India, the phe- nomenon of the perpetual snow is regulated by the same laws. From the longitude of Upper Assam in 95° E. to that of Kasli- mir in 75° E. the lowest limit of perpetual snow is about 15,000 feet, and the mass of Rhododendrons affect the most humid locali- ties near it, at 12,000 to 14,000. Receding from the plains of India and penetrating the mountains, the climate becomes drier, the snow line rises, and vegetation diminishes, whether the elevation of the land increases or decreases, plants reaching 17,000 and 18,000 feet, and the snow line 20,000 feet. To mention extreme cases: the snow level of Sikkini in 27° 30' is at 15,000 90 CLIMATE AND VEGETATION OF feet, and of vegetation at 14,500 ; whereas in lat. 35° 30' Dr. Thomson found the snow line 20,000 feet in Karakorum, and vegetation up to 18,000 feet — features common also to Sikkim in lat. 28°. Of the Sikkim Khododendrons I have little further to say except with reference to the individual species, and I shall therefore arrange these in three groups, according to the elevations they inhabit, adding such notes upon each as may prove useful in their determination and assist in their cultivation. No species that I am aware of extends much below 6000 feet in Sikkim, or in the Himalayas generally, though, according to Mr. Griffith, R. arhoreum is found below 4000 on some of the dry rocky outer ranges of Bhotan. In this respect, however, the latter country is very exceptional, and demands a passing notice. The Khassya mountains, as I have elsewhere shown, shield the lower ranges of Bhotan from the effects of the southerly monsoon ; they rise to an average height of 5000 feet, extending (as the Gar- rows, westward, and Jyntea hills, eastward) for about 250 miles parallel to and 60 miles south of the Bhotan Himalaya, the inter- vening valley being that of the Burrampooter river. The mon- soon from the Bay of Bengal is in this longitude a S.S.W. one, and after traversing 200 miles, partly of the Sunderbunds and partly of a very peculiar marsh district called the J heels, it dis- charges an amoimt of water on the abrupt southern face of the Khassya which, as a rain-fall, I believe has no parallel in the world, amounting to between 400 and 500 inches a-year. Sud- denly deprived of one-third of its water, the current pursues its course northward, traversing 30 miles or so of hills, whereby it is cooled ; while it is again warmed in the moist valley of Assam. What is thence carried on to the Bhotan Himalaya is not con- densed on the mountains till it reaches a considerable elevatioUj 5000 feet and upwards, where it is cooled and deposits moisture abundantly. The Bhotan Himalaya is therefore very dry below 50OO feet, and humid above that, but never so nmch so as Sikkim. R. arhoreum is found at 4500 feet on the Khassya (but not near the southern edge of the range), and ascends to 7000 feet* There are several other Khassya species, all avoiding the southern parts, though one of them descends to 2000 feet on the north flank. Most of the species, as well as those of the Malay peninsula, Java, and Borneo, belong to the same section with R. cinnaharinum, having comparatively long tubes to the corolla and small calyces, or none. The Borneo species* gathered by Mr. Low on Kini Balu, * Many of these species will be figured shortly in Sir Wi J. Hooker's * Icones Plantarum.'

Thirteen kinds found below 8500 feet, on a mountain unexplored beyond that height, and in a country but once ascended so high, argues a profusion of species in the mountainous regions of that island of which we can form no adequate idea.

It forms a tree 30 feet high ; trunks solitary, or two or three together, spreading, branched above, the bark pale, and the branches leafy at the apex. Leaves very beautiful in the leaf- buds, at first enveloped in erect and silky scales, so closely im- bricated and so large as to resemble the cones of some species of pine ; the outer or loM'er scales broad and coriaceous, glabrous, of a reddish-brown colour, the innermost ones oblong-spathulate, pubescent. When fully developed the leaves are among the largest of the genus, 6 inches to a foot long, 3 to 5 inches broad, full green above, beneath silvery white. Bracteas deci- duous, densely silky. Flowers 2 to 3 inches long, 2 to 2^ inches in diameter, inodorous, always white. — In the silvery underside of the foliage, but in nothing else, this resembles R. arboreum^ while the blossoms are often as large as those of R.

On Sinchul, the higher parts of the mountain, from 8000 to 9,000 feet of elevation, are more or less clothed with it ; on Tonglo, as it approaches 10,000 feet, it is suddenly replaced by R, Falconeri. It seemed to be shy of flowering in the season of 1848, for it was with difficulty I could then procure sufficient specimens to complete my drawing; in 1849 it flowered pro- fusely, and, with the white magnolias, formed at a considerable distance a conspicuous object amid the lurid green vegetation of the mountains. 2, R, barbatum, — Distribution and range : Kemaon, Nepal, Sikkim, and Bhotan ; 8000 to 1 1 ,000 feet ; confined to tlie dampest wooded regions, A tree 30 to 40 feet high, branched from the base.

Petioles sometimes quite deprived of hairs. Flowers moderately sized, blood-colour, collected into a compact globose head 4 to 5 inches in diameter. Bracteas oblong or ovate, the inner ones silky, all more or less glutinous. — One of the most beautiful of the Himalayan species, but variable in size and habit. I have seen it forming a low shrub in mossy swamps, and then entirely destitute of bristles on the leaf and flower stalks ; in such a state it was figured and described as R. lancifolium. 3. R. arboreum. — Distribution and range : throughout the Himalaya. 5000 to 10,000 feet. Most frequent in the drier valleys and ridges. Of this well known species no description is necessary : it abounds in the inner ranges of Sikkim, descending to 5000 feet beyond the first great ridge ; on that ridge, on the other hand, it is very rare, never descending below 7500 feet, and only appearing in exposed places. It prefers a drier soil and locality than most other species. The leaves are very variable in shape and in the form of their base, which tapers into a foot-stalk or is cordate ; their under surface is generally silvery white, but as the species attain higher elevations they become yellower, and finally rusty underneath, as in the variety CamphellicE. The seedlings partake of the habit, colour, and texture of their parents in a remarkable degree, whence the diflficulty of recog- nizing R. arboreum under several very common forms in our nurseries. A jelly is made from the flowers of this plant in the N.W. Himalaya, but I have never seen the preparation. The honey of wild bees is at the flowering season said to be poison- ous in Sikkim, but opinions are divided as to whether R. ar- boreum or R. Dalhousics is to blame ; if either, I suspect it to be the former, which alone is abundant near the localities where the bees abound. After a verv' careful examination I have come to the conclu- sion that the R. Campbellice is only a variety of this ; and I further include the R. nobile, "Wall. ; R. Nilagaricum, Zenker ; and R. Zeylanicum. Its geographical distribution is therefore Ceylon, the peninsula of India, the Khassya mountains and the Himalaya mountains from Upper Assam nearly as far west as the Indus; between the elevations of 5000 and 10,000 in Bhotan, Sikkim, Nepal, and Keniaon, but only between 5000 and 7000 elsewhere. It is not found in the valley of Kashmir, but on the south flanks of the mountains bounding that valley on the south. EAST NEPAL AND THE SIKKIM HIMALAYA INIOUNTAIXS, 93 4. R. niveum. — Distribution and range: Sikkim — 10,000 to 12,000 feet — in moist valleys of the interior. This species forms a tree so similar to R. arboreum, that I much doubt its being distinct. The snowy white down is pecu- liar, as are the short capsules, and in my ignorance of the flowers I rest its claims upon these characters alone. I have not recog- nized young plants in cultivation. 5. R. Dalhousice. — Distribution and range : East Nepal, Sikkim, and Bhotan (Griffith)— 6000 to 9000 feet— in Immid forests, generally growing on limbs of trees. The seeds of this species have germinated as freely as any, and the young plants are making rapid progress in a cool moist house. The young leaves are very hairy, which character and their tenderness distinguish tliem. They most resemble R. cili- atum, but the latter is more hairy, of a darker colour, and rigid texture. — A straggling shrub, 6 to 8 feet high, generally growing, like tropical Orchideae, among moss, with ferns and Aroide£e, upon the limbs of large trees : the stems clothed wiih a reddish, papery bark, the branches straggling in distant whorJs ; each branch bearing its leaves and flowers only at the extremity. Leaves few, spreading or reflexed, about 4^ to 5 inches in length, footstalk about ^ an inch long, the margin plane (not revolute), the upper surface darkish green, inclining to yellow ; beneath paler, dotted with very small, scattered, rusty-coloured scales. Flowers 3 to 7 in a terminal, umbellate head, the spread of which is greater than that of the leaves. Corolla 3^ to 4t inches long, and as broad at the mouth ; at the contracted base of the tube are 5 deep pits. Lobes of the limb nearly equal, very broad, rounded, waved, spreading. The flowers are white, with an occasional tinge of rose, in size and colour almost resembling those of the white Bourbon Lily (^Lilium candidum) ; in age they assume a delicate roseate tinge, and sometimes become spotted with orange, which rather adds to their beauty than detracts from it. Tiiey are lemon-scented, and very fragrant. 6. R. Griffithii. — Distribution and range : Bhotan and Sikkim — 7000 to 9000 feet — in the valleys and ridges of the interior only, where the climate is drier. It forms scattered bushes, 4 to 8 feet high, branching from the base, where the trunk is 6 inches in diameter. Branches sub- erect, copiously leafy. Bark smooth and papery. Leaves vari- able in size and breadth, but large for the size of the plant, 4 to 10 inches long; margin plane, often tinged with yellow; upper 94 CLIMATE AND VKGETATION OF surface lii^ht full green ; the under paler, slightly glaucescent. Flowers the largest of the genus, variable in size, terminal, 3 to 5 together, inodorous. Peduncles rather slender, longer than the petioles, red or green. The calyx represents a shallow, concave, irregular, subrhomboid-shaped platter, ]! inch in its greatest diameter ; the back marked with sliglitly elevated, radiating lines, glossy, as if varnished. Corolla white, tinged with pink, veiny, of a firm, rather fieshy texture : tube short for the size of the flower, yellowish and rose-colour towards the base, the mouth very wide, lobes exceedingly large and spreading. I have measured some only 3 inches across, but others 5 and 5:^ inches in diameter! —I have found but few plants of this superb species, and in these the inflorescence varied much in size. The speci- mens from which the drawing in Sikkim Rhod. (under the name of R. Aucklandii, PI. XI.) was made were from a bush covered with blossoms, growing in a rather dry, sunny exposure, above the villa-^e of Choongtam. The same species also grows on the skirts of the pine-forests {Abies Briinoniana) above Lamleng, and it is there conspicuous for the abundance rather than for the large size of its blossoms. When I described this plant I was not aware of its being the R. Griffithii of Dr. Wight's Icones Plant. Ind. Or., the draw- ing of which seems to have been prepared from very bad ma- terials. The great size of the corollas figured in the " Sikkim Rhododendrons " may be due to tlie individual being sterile, for I found the anthers to contain little or no pollen. 7. R. Edyeworthii. — Distribution and range: Sikkim — 7000 to 9000 feet — in forests of the dampest regions. Leaves 2 to 4 inches long. Corolla white, often tinged with blush or pale yellow : tlie tube rather short, widening much at the mouth, slightly curved, the limb unusually large, more than 4 inches across, spreading, of 5 nearly equal, rounded, slightly emarginate lobes, crisped at the margin, delicately veined on the surface. — A truly superb species, from the size of the flowers and their roseate tinge on a white ground, also from the varietj^ of rich colour in the leaves, bracteas, stipules, calyx, &c., while the very wrinkled surface of the leaf adds much to its beauty. In its floccose character and foliaceous calyx it resembles R. pendu- lum; but in the size and shape of the flowers it approaches R. DalhousicE, next to which I would place it. The majority of my specimens were obtained from the land-shoots or slips in the rocky ravines, wliich bring down in their course those pines on the limbs of wliich this species delights to grow. EAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAINS. 95 8. R. Maddeni. — Distribution and range : Bhotan (?) and Sikkim — where it was found in the inner and drier valleys only, and very rarely there, at 6000 feet ele- vation. A shrub 6 to 8 feet high. Leaves abundant, of a coriaceous substance but flaccid, 4 to 7 inches long, frequently pendulous. Corolla Zh to 4 inches long, and as much across the limb, very handsome, white with a faint blush chiefly on the upper lobe, rather fleshy, but firm in substance ; in shape much more con- tracted than is usual with the Himalayan species : the limb very large, spreading, of 5 nearly equal, rounded, entire lobes, slightly crenato-undulate at the margin, delicately but obscurely veined. The foliage and flowers are faintly odorous. This species clearly belongs to the same natural group as R. cinnabarinum ; from which, however, the very large white flowers, the numerous stamens, and ten-celled fruit abundantly distinguish it. 9. R. ciliatum. — Distribution and range : Sikkim — > 9000 to 10,000 feet — in rocky valleys of the interior. This forms a small very rigid shrub, growing in clumps 2 feet high, generally in moist rocky places. Odour faintly resinous and pleasant. Corolla 1^ inch long, nearly as much across at the mouth ; tube rather contracted below, limb 5-lobed, colour pale reddish-purple; upper lobe obscurely spotted. Allied to R, harbatum, but widely different in stature, habit, and the scattered scales on the under surface of the leaves. I have not observed it in other valleys than those flanked by snowy mountains, where it is common, scenting the air in warm weather. The scales (as in its congeners) are orbicular, sessile, attached at the centre, formed of 3 concentric series of cells surrounding a central one, in which a resinous fragrant oil is secreted. 10. R. virgatum. — Distribution and range : Hhotan and Sikkim— 1000 to 9000 feet— in damp valleys of the interior. Under this I have included two species figured in the " Sikkim Rhododendrons" which are perhaps only extreme varieties. Tlie characters common to both are a slender twiggy habit, a height of 3 to 6 feet, glaucous leaves, and a perfect identity in all essential characters of inflorescence and fruit. The shape of leaf is a variable one in all cases, as are the size and colour of flower, upon which characters R. triflorum was founded. The latter is by far the handsomer plant, and grows at lower elevations. The following remarks apply to it : — 96 clijMate and vkgetation of Var. triftorum forms a slirub 4 to 6 feet liigli, with erect and rather twiggy branches. Leaves frequently pendulous, on rather short, slender petioles (4 of an inch long), ovato-lanceo- late, approaching to oblong or elliptical, 2 or 3 inches long, the margin a little recurved, substance rather thin, upper surface smootli and shining, under quite glabroiss and glaucous, but so beset with ferruginous scales as to partake of that colour. Peduncles generally 3 together, terminal, ^ to f of an inch long, slender, erect. Corolla greenisii -yellow, in shape much resem- bling that of the common garden Azaleas, having a somewhat obconical tube very open at tiie mouth, and a limb of 5 spreading oblong entire segments, which are slightly veiny, nearly 2 inches across the lobes. 'R.virgatum itself has stems and branches 4 feet high, scarcely the thickness of a crow-quill. The leaves are in form and size like those of R. (jlaucum. Flowers solitary, rarely in pairs, and axillary ; the pedicels 2 to 3 lines long, covered with sheathing, deciduous, coriaceous, brown scales, wliich are longer than the pedicel, very rigid in texture, downy on the back. Corolla a pale red-purple, smaller tiian that of Var. triflorum^ but of the same form ; the tube short, narrow, and obconical, tlie segments narrow and spreading. 11. R. vaccinioides. — Distribution and range: Sihkim ■ — 6000 to 8000 feet — in very moist situations of the outer and inner valleys. The flowers of this species were unknown to me when I pub- lished the second Fasciculus of the " Sikkim Rhododendrons," and I consequently placed the species in a wrong section of the genus. An excellent drawing, prepared by my friend the late Mr. Cathcart, represents the flower and fruit ; it will shortly be pub- lished in Sir W. Hooker's Icones Plantarum. In the synoptical account of the species given above I have associated it with R. caynellicpjlorum, &c., with which it further agrees in its fre- quently epiphytical habit. It is not now alive in this country, and, being of no beauty, it may be long before it is so. In the neighbourhood of Darjiling it is very abundant. A small, very slender, straggling species, sometimes pendulous from trunks of trees, and then 2 feet long, of a bright green colour, and so like a common Sikkim species of Vaccinium (V. ohovatimi, Wight, Icon., t. 1193) as not to be distinguishable at first sight. Stems no thicker than a dove's quill, rough with tubercles, indicating the former ])osition of scales, which still clothe the branchlets, petioles, and more sparingly the under surface of the foliage. Leaves coriaceous, ^ to an inch long, obovate or even spathulate, the blade narrowed downwards to EAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAIXS. 97 the very point where it meets the stem ; upper surface a bright green, lower paler. Flower-stalks as long as the leaves, slender. Flowers nodding, white, nearly half an inch across, of the same form as those of R. setosum and R. lepidotum, having a short, swelling, almost spherical tube, and spreading or recurved round lobes. Stamens projecting far beyond the tube. Seed-vessels curved, unlike those of any other species, being slender and membranous, pale-brown, an inch long, scarcely ^ in diameter, valves linear, a little scaly on the back. II. Species of the Middle or Alpine Zone, answering to the Alpine region of Southern and the Subalpine of Middle and Northern Europe, to the climates of the Scotch Fir, &c. (10,000 to 14,000 feet). 12. R. Falconeri. — Distribution and range: East Nepal and Sikkim — 9000 to 12,000 feet — in moist forests. A tree 30 feet in height ; 2 or 3 trunks springing from the same point, often 2 feet in diameter. Bark pale and smooth ; branches few, spreading, leafy at the tops ; young leaves clothed with velvety down, and when in bud concealed by downy gluti- nous scales, of which the outer are subulate, the inner ovate. The perfect leaves are very coriaceous, from 8 to 20 inches long, and 5 to 12 inches wide, the upper side glossy green, but fading into yellow at the margins, which are quite plane (not recurved) beneath ; clothed with a short, dense, pale, ferruginous down, except on the mid-rib and reticulated veins. Leaf- stalks long and very thick, plane and glabrous above, clothed beneath mth dark rusty down. Heads small, composed of numerous white, densely placed flowers. This is a most striking and distinct species, of which the foliage resembles the ferruginous-leaved Magnolia grandiflora. The dense many-flowered head, the multiplication of the lobes of the corolla, and of the stamens and fruit-cells, and the exserted style, bring it very near R. grande (Wight's Ic. PL, vol. iv., t. 1202), a Bhotan species found by Mr. Griffith ; but the foliage is totally different. The flowers and leaves of this species usually attain a much larger size than those represented in the " Sikkim Rhododen- drons." 13. R. Hodgsoni. — Distribution and range : East Nepal, Bhotan, and Sikkim— 10,000 to 12,000 feet — in humid forests. A small tree, from 12 to 20 feet, branching from the base, VOL. VII. H 98 CLIMATE AND VKGETATION OF main branches as tliick as the human tliigh, spreading horizon- tally 20 or 30 feet evei-y way, interwoven with the adjacent plants and shrubs. Bark smooth, pale Hesh-coloured, flaking off in broad membranous patches. Wood white, very close-grained, soft yet tough, neither w^arping nor splitting, but, in consequence of the great compression of the larger branches, rarely affording a sample a foot square. Leaves terminal on the end branches, ample, spreading, 12 to 18 inches in length, of a singularly thick coriaceous texture, glabrous and bright glossy green above ; beneath, all except the thickened costa, clothed with a pale silvery white, rarely ferruginous, closely appressed wool, but which is easily rubbed off by the finger, and is often itself eva- nescent. Heads 4 to 6 inches in diameter, of several delicate, pale purple or rose-coloured flowers. Flower-stalks short, viscid, often downy. Corolla large, the tube IJ inch long, broadly campanulate, the base depressed at the insertion upon the flower- stalk, the margin of the depression lobed, limb spreading, 2 to 2^ inclies across, 8-lobed. This, and its associate the Abies Wehbicma, I have always regarded as characteristic plants of 10,000 to 12,000 feet in all the interior parts of Sikkim. 7?. Hodgsoni, in this respect, ranks with R. arhareum and M. Campbellice, being found in a loftier zone of Rhododendrons, succeeded by the arctic one of R. anthopogon, R. setosum, R. elcEcignoides, and finally, far above the ordinary limit of pheenogamic vegetation, by R. nivale, which is found at an elevation of 18,000 feet. Within the limits assigned to the present species, the traveller's attention is continually arrested by its magnificent and brilliant deep green foliage, as large as that of R. Falconeri. In summer the leaves spread all around the plant ; in winter they are rolled up, shrivelled, and pendulous from the tips of the branches. It is found alike at the bottom of the valleys, on the rocky spurs or slopes of the hills, in open places, or in the gloomy pine-groves, often forming an impene- trable thicket, not merely of twigs and foliage, but of thickset limbs and stout trunks, only to be severed with difficulty, on account of the toughness of the wood. As it is easily worked, and Jiot apt to split, it is admirably adapted for use in the parched and arid climate of Tibet ; and the Bhoteas make from it cups, spoons, and ladles, and the saddle, by means of which loads are slung upon the " yak." The leaves are employed as platters, and serve for lining the baskets which contain the mashed pulp of Ariscana root (a kind of Colocass) ; and the customary present of butter or curd is always enclosed in this glossy foliage. EAST NEPAL AND THE blKKIJl HIMALAYA MOUNTAINS. 99 14. R. Thomsonl (and R. candelabrum). — Distribution and range : East Nepal and Sikkim — 1 1,000 to 13,000 feet — in moist valleys. A bush 6 to 10 feet high, or in damp woods 15 feet, but then spare and woody. Lower branches stout, a foot in diameter ; upper slender, leafy at the extremities. Leaves 2 to 3 inches long, very broad, much resembling those of R. campijlocarptim, only that in the latter the leaf-stalks are often glandular, here never ; the texture of the leaves is coriaceous, but not very thick, the colour pale green, below sub-glaucous, everywhere quite gla- brous. Flowers in a head of 6 or 8 together from the ends of short branches among the leaves, on stalks an inch or more long, which radiate, as it were, from a centre, spreading horizontally, or curving downwards. Corolla remarkable for its almost un- rivalled deep blood-red colour and glossy surface, yielding only to R. fulgens ; deeper coloured than that of R. arbor eum ; the tube elongated, often vertically compressed, 2 inches long; the limb large, spreading, 5-lobed, the lobes notched, upper ones spotted. This species is perfectly inodorous. In the base of the corolla is secreted much honey, which is not considered poisonous, like that yielded by R. Dalhousice and R. argeniemn. The two latter species are said to render deleterious the wild honey which is collected during their flowering season. ' 15. R. Wightii. — Distribution and range: East Nepal and Sikkim — 12,000 to 14,000 feet — alpine valleys, abundant. A small shrubby tree, yielding, in beauty of inflorescence, to none amongst tlie yellow-flowered group to which it belongs. The trunks are often as thick as the thigh, and branch very much both upwards and outwards, forming a thickset shrub of 10 feet high. Leaves 6 to 8 (rarely 10) inches long, 2h to 3 broad, very coriaceous, more plane tlian is usual in the genus, bright green above, beneath covered with a very closely appressed opaque wool of a deep rufous colour, rarely pale and nearly white in the young foliage. Heads much larger than those of R. arboreum, 12 to 2U-flowered, the flowers not densely packed. Bracteal scales chesnut-brown, very coriaceous and viscid. Flowers have a faint honeyed smell ; foliage inodorous. This exceedingly handsome and abundant species replaces the R. Hodgsoni in ascending the moiuitains, and is the most prevalent species at 12,000 and 13,000 feet, conspicuous at all seasons for its large foliage, of a rusty cinnamon-colour beneath, and for its viscid buds. 100 CLIMATE AND VEGETATION OF 16. Iv. campanidahnn. — Di.stribution and range: Ke- maon, Nepal, Si/ikim, and Bhotcm — 10,000 to 14,000 feet — where it is abundant in all parts of Sikkini. This well-known species is commonly cultivated in our gar- dens, and requires no particular description. It is wholly inodo- rous, and the flowers are very variable in colour, being of a deeper or paler lilac, often spotted inside the corolla. The variety I liave called Wallicliii is nearly destitute of wool on the under- surface of the leaf, and 11. (erugiuosum, another variety, diflers only in the purple capsules and curious verdigris-green colour of the young foliage. This and the following are the great orna- ments of regions above 12,000 feet, where they often cover the flanks of the valleys with their rich green foliage and gaudy blossoms. 17.

Supposing the same law to apply (wliich I exceedingly doubt) to heights above 19,000 feet, 2° would be the mean annual temperature of the summit of Kinchinjunga, altitude 28,178 feet, the loftiest known spot on the globe. The upper limit of plienogamic vegetation coincides with a mean temperature of 30° on the south flank of Kinchinjunga, and of 22° in Tibet ; in both cases animals and perennial-rooted herbaceous plants are to be found at elevations corresponding to these mean temperatures, and even at higher elevations in shel- tered localities, I have assumed the decrease of temperature for a corresponding amount of elevation to be gradually less in ascending (1° =320 feet at 6000 to 10,000 feet, and 1° = 400 feet at 14,000 lo 18,000 feet). My observations appear to prove this, but I do not regard them as conclusive ; supposing them to 110 CLIMATE AND VEGETATION OF be SO, I attribute it to a combination of various causes, especially to the increased elevation and yet unsnowed condition of the mass of land elev-ated above 16,000 feet, as is shown in the woodcut (p. 85) ; also to the greater amount of sunshine there, and to the lesser density and height of the fogs wiiich obstruct the sun's rays at all elevations. In corroboration of this I may mention that the difference of temperature is much less in sum- mer than in winter, 1° of Fahr. being equivalent to only 2oO feet in January between 7000 and 13,000 feet, and to upwards of 400 feet in July. Again, at Darjiling (7500 feet) tlie tem- perature hardly ever rises above 70° in the summer months, yet it often rises even higher in Tibet at 12,000 to 14,000 feet. On the other hand, the winters, and winter nights especially, are disproportionately cold, the thermometer falling upwards of 40° below the Darjiling temperature at 6000 feet above that elevation. The diurnal distribution of temperature is equally and simi- larly affected by the presence of vapour in the tliree different zones. The lower zone is first clouded, because the lower ranges, of 6000 to 10,000 feet, first receive the diurnal charge of vapour- loaded southerly winds ; the middle gets more of the sun's rays, and the upper more still. Though the summer days of the upper zone are warmer than their elevation would indicate, tlie niglits are not proportionally colder ; for the light mist of 14,000 feet, which replaces the dense fog of 7000 feet, effectually ob- structs nocturnal radiation, though it is less an obstacle to solar radiation. Clear nights, be it observed, are as rare at 14,000 as at 7000 feet, the nights being rainy, if windy ; or, if calm, cold currents descend from the mountains, condensing the moist vapours of the valleys, whose narrow floors are at sun- rise bathed in mist at all elevations in Sikkim. The rise and dispersion of these dense masses, and their collection and recun- densation on the mountains in the morning, is one of the most magnificent phenomena of the Himalaya, when viewed from a proper elevation ; it commences as soon as the sun appears on the horizon. The mean daily range of the thermometer at 7000 feet is 13° in cleared spots, but considerably less in wooded, and certainly one-third less in the forest itself. At 11,000 feet it amounts to about 20°, and at 15,000 feet to 27° (London 17-5°). These values vary widely in the different months, being much less in the summer or rainy months. At 7,000 feet it amounts to 8°-9° in Aug. and Sept., and 17° in Dec. 11,000 ,, 12° ,, ,, 30 15,000 ,, 15 ,, ,, 40 ,, London ,, 20 ,, ,, 10 EAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAINS. HI Temperature of the earth. — This, at 2^ to 3 feet depth, varies %vith the temperature of the month, but is hardly affected by the diurnal variation, except in extreme cases. In summer, throughout the rains, May to October, the temperature is that of the month, which is imparted by the rain to the depth of 11 feet during severe continued falls (of 6 to 12 inches a day), on which occasions I have seen the buried thermometer indicat- ing a temperature above the mean of the month. Again, in the winter montlis, December and January, it stands 5° above the monthly mean ; in November and February 4° to 5° ; in March it is a little below the mean temperature of the month, and in October above it ; April and May being sunny, it stands above their mean temperature ; June to September a little be- low the mean temperature of each respectively. In the middle and upper zones the sunk thermometer always stands considerably above the mean of the month, the sun's rays being more powerful and frequently felt, the rain less ; and the earth, being cooled less by nocturnal radiation than it is warmed by solar, accumulates heat to a certain depth. Thus in January, at 13,000 feet, I have found it 17° above the mean temperature, though the soil was frozen hard for 16 inches; and in July, at the same elevation, 7'5° above the mean temperature. In August I have seen it + 8° at 12,000 feet, in September + 74° at 15,400 feet, and in October + 12° at 16,800 feet; in July -|-7'6° at 12,800 feet, and in October -f 10*5° at the same spot ; in December + 9^ at 13,500 feet with several inches of frozen soil. It is probable that the intense winter cold of the upper zone does not materially affect the soil at 3 feet deptli, for there is always a sufficiently deep covering of snow^ after the second week of January to protect the soil from excessive cold. Solar radiation. — From a multitude of desultory observations with the black bulb thermometer, I conclude that at 7000 feet, 67° above the temperature of the air is the average maximum effect of the sun's rays on a black bulb thermometer* through- out the year, amounting rarely to + 70° and + 80° in the summer months, and more frequently in the winter. These re- sults, though greatly above what are obtained at Calcutta, are not much, if at all, above what prevail at the foot of the hills and up the Gangetic valley. This effect is greatly increased with the elevation. At 10,000 feet, in December, at 9 a.m., I saw it mount to 132° with a diff. of -1-94°, whilst the tempera- ture of sliaded snow hard by was 22°; at 13,100 feet, in * From the mean of very many observations I find that 10° is the iiveriige (UfFerence between two otherwise equal and similar white and black bulb thermometers at the level of the sea. 112 CLIMATE AND VEGETATION OF January, at 9 a.m., it has stood at 98°, difF. + 68-2°, and at 10 A.M. at 114°, difF. + 81-4°, wliilst the radiating thermo- meter on the snow had fallen at sunrise to 0'7°. In December, at 13,500 feet, I have seen it 110°, difF. + 84° ; at 11 a.m., 11,500 feet, 122°, difi; + 75°. In November, 9 a.m., at 13,500 feet, 112°, difF. 4- 82°. This is but a small selection from many, of the extraordinary power of solar radiation in the coldest months at great elevations. It is accompanied by a great increase of solar light, as I found by means of the black glass photometer. Two phenomena particulax'ly obstruct the solar light and heat — the clouds and fog from the end of May till October, and the haze from February to May. On the former I have dwelt suffi- ciently at length. Two months alone are usually clear, one before and one after the rains, when the air, thougli still humid, is transparent. The haze has never been fully explained, though a well-known phenomenon. On the plains of India, at the foot of the iiills, it begins generally in the forenoon of the cold season, with the rise of the west wind, and, in February especially, obscures the sun's disc by noon ; frequently it lasts throughout the 24 hours, and is usually accompanied by great dryness of the atmosphere. It gradually diminislies in ascend- ing ; it cannot be said to prevail at 7000 feet, and I have never experienced it at 10,000. At 7000, however, it very often, in April, obscures the snowy ranges 30 miles off, which are bright and defined at sunrise, and either pale away or become of a lurid yellow-red, according to the density of this haze, as they disappear at 10 A.M. I believe it always accompanies a S.W. wind and dry atmosphere in Sikkim. Nocturnal radiation. — This is even a more difficult pheno- menon for the traveller to estimate than solar radiation, the dano-er of exposing instruments at night being always great in wild countries. I have used the parabolic reflector and white cotton most frequently, and find no material difference in the means of many observations of each, though often 1° to 2° in individual ones. Avoiding radiation from surrounding objects is very difficult, especially in wooded countries. I have also tried the radiating power of grass and the earth ; the latter generally is lower, the former higher than the thermometer ex- posed on cotton or in the reflector, but much depends on the surface of the herbage and soil. Snow radiates the most power- fully of any substance I have tried ; in one instance, at 13,000 feet, in January, the thermometer on snow fell to 0*2°, which was 10"8° below the temperature at the time, grass showing 67°, and on another occasion to 1*2°, when the air at the time (before sunrise) was 21*2°, and the difference 20°. I Jiave frequently made this observation, and always with a similar result ; it may EAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAINS. 113 'account for^tlie great injury plants sustain from a thin covering of ice on their foliage, even when tlie temperature is but little below the freezing point. The power of terrestrial radiation increases with the elevation, as does solar radiation, but not in an equal proportion. At 7000 feet there is little radiation during the rains ; the nights are almost invariably cloudy — 3° to 4° is the mean maximum, but it is not on one night out of six that there is any radiation. From October to December the amount is greater = 10° to 12°, and from January till May greater still, reaching 15°. During the winter months the effect of radiation is often felt throughout the clear days, dew forming abundantly at 4000 to 8000 feet in the shaded bottoms of narrow valleys, into which the sun does not penetrate till 10 a.m., and from which it dis- appears at 3 P.M. I have seen the thermometer in the reflector fall 12° at 10 A.M. in a shaded valley. This often produces an anomalous effect, causing the temperature in the shade to fall aftei" sunrise ; for the mists which condense in the bottoms of the valleys after midnight disperse after sunrise, but long before tlie sun reaches the valleys, and powerful radiation ensues, lower- ing the surrounding temperature. A fall of 1° to 2° after sun- rise of air in the sliade is hence common in valleys in November and December. The excessive radiation of the winter months often gives rise to a curious phenomenon ; it causes the forma- tion of copious dew on the blanket of the traveller's bed, which radiates to the tent roof, and this inside an open or closed tent. I have experienced this at various elevations, from 6000 to 16,000 feet. Whether the mininum temperature was as high as 50° or but little above zero, the effect is the same, except that hoar frost or ice forms in the latter case. Another remark- able effect of nocturnal radiation is the curl of the alpine Rhododendron leaves in November, which is probably due to the freezing and consequent expansion of the water in the upper strata of cells exposed to the sky. The first curl is generally repaired by the ensuing day's sun, but after two or three nights the leaves become permanently curled, and remain so till they fall in the following spring. Many alpine plants resist a great degree of radiation ; the Cyananthus, especially, I have observed to be uninjured by a minimum temperature of 31'0° lowered 12'0° by radiation, in the month of September, at 15,500 feet; and yet this is one of the most delicate as well as beautiful of Himalayan blossoms. As a general rule, however, the commencement of the Septem- ber and October radiation is the signal for the extinction of the alpine herbaceous vegetation. I have elsewhere said that the nocturnal radiation of the 114 CLIMATE AND VEGETATION OF English spring months is the great obstacle to the cultivation of many Himalayan plants ; it is not hence to be inferred that there is no similar amount of radiation in the Himalaya, for, on the contrary, in April its amount is much greater than in England, equalling 13° of difference frequently, and I have seen 16° at 7500 feet; but the minimum temperature at the time is 51°, and the absolute amount of cold hence immaterial. The mean minimimi of London is 38"0°, and when lowered 5*5° by radiation the consequent cold is very considerable. Mr. Daniell, in his admirable essay on the climate of London (the perusal of which first gave me an interest in these pursuits), mentions +17° as the maximum effect of nocturnal radiation ever observed by him ; I have had +20° from the surface of snow, and I have registered + 13-0°, + 14-0°, + 15-5°, and + 16-0° in April at Darjiling ; nearly as much at 6000 feet in February ; once + 12-0°, twice +13-0°, and once + 14*2° in September at 15,500 feet; +10° in October at 16,800 feet ; + 1 10°, + 1 2-0°, and nearly +13-0° in January at 7000 feet; +10° to + 14-5° repeatedly in February at that elevation, and + 12° to + 14"7° at 10,000 feet in November on several occasions. To conclude, though nocturnal radiation does occur frequently, and lias on the whole a much more ])owerful effect in Sikkini than in England, I doubt if the mean effect of all the months in Sikkim would equal that of London, from so many more nights being cloudy, which cloudy atmosphere and the comparatively high temperature of the nocturnal radiating months are what a Himalayan vegetation wants in England. Winds. — Of the Himalayan winds there is little to be said affecting the horticulturist. The southerly moist, warm current is perennial, except during the spring months, when occa- sional S.AV. squalls or moderate day winds blow. The nights are usually calm, or return cool winds sweep gently down the valleys. The northerly winds are said to bring snow ; in December to February they appear to me to be local phenomena, and are under currents from the snowed regions, which condense and freeze the lower strata of the main current. Heavy gales occur at the equinoxes in the Himalaya as all the world over, but I have never experienced cyclones or hurricanes. Mid- summer and midwinter are also generally characterised by storm and rain. Atmospheric presstire. — It has long been surmised that an alpine vegetation may owe some of its peculiarities to the dimi- nished atmospheric pressure ; and that the latter being" a condition which the gardener cannot supply, he can never successfully cultivate alpine plants in general. I know of no foundation for this hypothesis ; many plants, natives of the level of the sea EAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAINS. 115 in other parts of the world, and some even of the hot plains of Bengal, ascend to 12,000 and even 15,000 feet on the Himalaya, unaffected by diminished pressure. Any quantity of species from low countries may be cultivated, and some have been for aIay is its flowering season in its native locality, and a purplish red the colour I have been accustomed to see it. Sikkim climate as compared with London. — The colder win- ters and warmer summers are the prominent differences of the London climate, as the following comparison shows : — Mean Temp. July. January. Range. Mean Max. London . 50-0 . . 63-2 . . 36-0 . . 27-2 . . 71-0 Darjiling . 53'5 . . 61-4 . . 40'0 . . 21-4 . . 65-3 Mean Min, Extreme Max. Extreme Min. Extreme Diff. London . . 34-2 . . 94-0 . . -4-5 98-5 Darjiling . 38-2 . . 71-0 . . 25-5 . 46-.5 The extreme Darjiling data given here are not low enough for the minimum, or high enough for the maximum ; but they give a sufficient approximation. At 10,000 to 11,000 feet, where most species of rhododendrons grow, the climate in its main features of great extremes approaches nearer to the English ; but tlie mean temperature (40°) is too low. Our summers are nmch too hot for the plants of that elevation, and our winters being too mild, they make shoots earlier in spring than in the Himalaya, which are cut off by frosts in April. Though the temperature is more uniform in Sikkim, it presents one curious anomaly, which is, that an accession of 8° of temperature occurs in March, above February, the parallel of which does not occur till June in Eng- land, which is 8° warmer than May. This brings the rhodo- dendrons so early into flower at 7000 feet, and keeps the radiating thermometer always above freezing for the rest of the spring. Again, there is in London nearly 20° of average difference between the day and night temp, of April, and 22° in May, — months wherein 15° and 13° are the corresponding Darjiling differences. This is a very powerful obstacle to the cultivation out of doors of many otherwise very hardy Himalayan plants, which are impatient of sudden changes, and incapable of bear- ing sudden, sharp frosts in March and April. As the flowering season advances and fruit-setting comes on, the temperature in Sikkim becomes more markedly uniform, the mean difference between day and night being, in May, 13°; June, 11°; July, 10°. Li London it is not so: May, 22°; June, 21"6° ; July, 21*6°. Turningagain to the autumn solstice, the sudden fall of temperature occurs both in Sikkim and Lon- don ill November, and amounts in each to upwards of 7° ; but whereas the difference between day and night is increasing in Sikkim, it decreases in London, a circumstance which may affect ^Jje rijjening of seed, by checking tli(> vegetative organs. EAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAINS. 117 I have here taken the Darjiling elevation of 7000 feet as the standard of comparison between the Himalaya and London, and of course it is understood that I here speak of the cultivation of species of that zone ; but as most of the Himalayan plants have a range of fully 3000 feet, which equals a mean annual diti'erence of temp, of about 10°, it follows that localities with a mean annual temp, of 46° to 56° are in that one respect suited to the cultivation of species of the lower zone. It must also be borne in mind, that the temperatures are less uniform above 7000 feet in Sikkim, than at that particular elevation where the maximum of moisture prevails. Seasons, general remarks on. — These, throughout the Hima- laya, partake more or less markedly of the hot and cold, or wet and dry of the plains of Bengal, with this exception, that the dry westerly wind which sweeps across the plains during many of the winter months is scarcely felt in Sikkim, or in the after- noon only in occasional puffs from the S.AV. The southerly wind blows steadily from May till November, but is not uni- formly moist at all seasons; it attains its maximum of humidity in July and August, when, being warmest, its capacity for trans- porting moisture is also greatest. From November till April, calms and light winds prevail, with occasional gales. Electric disturbances are most frequent from March to May, and again at the end of the rains ; they are however almost wholly con- fined to the foot of the hills and outer ranges. The rainy season commences with a spring fall in April or May, which is the flowering seasons of all the rhododendrons, and of most of the magnolias of the lower zone (7000 to 10,000 feet). A I'emarkable uniformity of humidity and temperature now prevails at all elevations, till the fruiting season, which occurs in September at the upper zone, in October in the middle, and November and December in the lower zone. The rains have fairly " set in" by the middle or end of May, and the rho- dodendron flowers are withered within a month of their flower- ing, that is, by the beginning of June in both lower and middle zone, and but little later above 14,000 feet ; for though they bud so late in the alpine regions, vegetation proceeds there much more rapidly. In the upper zone May is the budding month, and the resinous scales that envelop the rhododendron flowers are no sooner thrown off than the leaves are expanded, and the flowers follow with that rapidity which is so characteristic of an arctic spring, and indeed of all excessive climates. The distribution of the seasons in the three zones is very pecu- liar, and gives rise to some anomalies that have puzzled natu- ralists. From the middle of October to that of May, vegetation VOL. VII. K ]]8 CMMATE AND VEGETATION OF is torpid above 14,000 feet, and indeed almost iinifonnly co- vered witli snow. From November till the middle of April, vegetation is also torpid in tiie middle zone (above 10,000 feet), except that a few trees and bushes do not ripen all their seeds till December. The three winter months (December, January, and February) are all but dead in the lower zone (above 6000 feet), the earliest appearance of spring at Darjiling (7000 feet) being at the sudden accession of heat in March. From May till August the vegetation in each zone is (in ascending order) a month behind that below it ; 4000 feet being about equal to a month of summer weatlier in one sense. I mean by tliis, that the genera and natural orders Avhich flower at, say 8000 feet in May, are not so forward at 12,000 feet till -Tune, nor at 16,000 feet till July. After August, however, the reverse holds good ; then the vegetation is as forward at 16,000 feet as at 8000 feet. By the end of September most of the natural orders and genera have ripened their fruit in the upper zone, though they have flowered as late as July ; whereas October is the fruiting month at 12,000, and November below 10,000 feet. The Rhododendrons offer good instances of this : — 16,000 to 17,000 feet, R. nivale flowers July; fruits September. 13,000 to 14,000 feet, E. nnthopogon flowers June; fruits October. 11,000 to 12,000 feet, li. campannlahtm flowers in May; fruits in Nov. 8,000 to 9,000 feet, R. argenteum flowers in April ; fruits in December. And so it is with many species of ComposittE and Umbelliferce, and indeed of all natural orders, some of wliich I have on the same day gathered in ripe fruit at 13,000 to 14,000 feet, and found still in flower at 9000 to 10,000. The brighter skies and more powerful and frequent solar radiation at the greater elevations, account for this apparent inversion of the order of nature. I shall conclude this long essay with some notices of the vege- tation of the months in the three zones specified, assuming the elevations of 7000 feet, 11,000 feet, and 15,000 feet, as typical of the three. I shall commence with March, which begins the new year as far as vegetation is concerned at 7000 feet. March. — In the lower zone, in which alone vegetation is active, the mean temperature is 50*7°, or 3° below the mean of the year, and 8° to 9° warmer than February. The mean maximum is 58'4°; 68° is the extreme temperature attained in the shade, and 120° in the sun, from my very insufl^icient data for solar radiation in this month. Tlie mean minimum is 43° ; the greatest cold 37°; and when aided by radiation 27'8° ; with a maximum difference of 9° between the minimum tiiermometer EAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAIN'S. l\Q and radiating one. The mean daily range is 1 5° to 1 6°, and the thermometer at 3 feet depth stands at 50°. The dew-point is 45-8° ; the mean humidity 0"8° to 09°, and the rain-fall about an inch, which generally comes in heavy showers of rain and hail, sometimes of sleet at the equinoxes. This is eminently the spring month at Darjiling. Laurels and maples bud and leaf, together with many other trees, but not oaks. The ground is often covered with the long leaf bracts of the Tetrantheras. The large white Michelia flowers, Cherry abiuidaiitly, white Rhododendron {cirgenleum') and the scarlet {arhoreum) in sunny spots. An early leafless Ccelogyne is common on the rocks {C. prfscox?), the small blue gentian covers the ground on grassy banks, with the yellow Fragaria Indica, Tormentilla, a few violets, a pretty blue Mazus, and some few Rubi. The Michelia, cherry, and rhododendrons are, however, the only conspicuous plants of this season and eleva- tion, with a pretty Uisporum in the woods. In the .garden peaches are in full flower, and many plants of the cold season of India, such annuals especially as belong to too cold or dry a climate to survive the damp heat of May and June if sown then — • stocks, for instance. Most other garden flower seeds and bulbs are planted now, as well as vegetables ; the young plants sown previously require transplanting and protection from the hail, which occasionally cuts up tender plants terribly. Potatoes are planted out. Table vegetables are still abundant of the ordinary kinds. Insects commence their attacks on the gardens.* April. — Mean temperature 56° ; of maxima 64°, and minima 48°; extremes 68° and 38°. Extremes of radiation— solar 125°, terrestrial 33°. Extreme differences — solar 66°, terrestrial 16°. The mean daily range is nearly 16°; sunk thermometer 60°; dew-point 50° ; and saturation 0-80°. Rain 25 inches. Most of the trees leaf and many flower in this month, as laurels, oaks, chesnuts. Hydrangea, birch. The smaller blos- somed Michelia and the large magnolias flower in profusion, and the woods at 8000 to 9000 feet in some years look mottled with their great white and red flowers. Maple leaves are broad and red. Birch hangs its catkins. Some pretty and conspicuous shrubs flower, as Adamia cyanea, a Viburnum, white honey- suckle, the beautiful purple Stauntonia, several white and pink Rubi, a very sweet Daphne in the woods (of which jjaper is made), and the curious" genus Helivingia. On the ground AriscBmas appear in profusion, and many other herbaceous plants leaf, as Aralia, Paris, and Polygona. Yellow strawberry, * I am indebted to my friend Dr. Campbell, the superintendent of Dar- jiling, for most of the garden memoranda of the month. K 2 120 CLIMATE AND VEGETATION OF Tornientilla, violets, and the ground-raspberry are common, with several Uispora, Oplnopogon, Melissa parvifolia, and Iso- pyrum ; beautiful white-Howered leafy Ccclogynes adorn the moist rocks, which, with a very fine Cymbidium on the trees, are common at and above 6000 feet. Little is doing in the garden more than was in March ; sowing and planting out go on with activity. English strawberries flower abundantly, as do currants. 3Iay. — Mean temperature 56'6° (only 1° above April). Means of maxima 6o"3°, and of minima 50° ; extremes 69° and 38°. Extremes of radiation — solar 125°, terrestrial 40°. Mean daily range 13-3°; dew-point 50°; saturation 0-91°. Rain 9 inches, falling in sharp showers late in the forenoon or after- noon of about half the days in the month. More falls in the night than in the day. The botanist may reap a rich harvest in this month, the jungle and mountain plants between 6000 and 10,000 feet" coming into flower in rapid succession. Of these the trees are — Yew (probably identical Symplocos. Walnut. ■with English). Alder. Eiio)ii/miis. Maples, various. Large-leaved oak. Myrsinece, various. Apple and several Pj/ri. Hydrangea. Olea. Photinia. Sauraitja. Podali/ria. Manglietia. Englehardtia. Ash. Lauri, various. The great magnolias and michelias, and large white Rhodo- dendron {argenteum), are all past flower. Of shrubs there are many and l)eautiful species — Woody climbers. Limonia. Ruhi, several (the yel- Staiintonia. Staiintonia. low-fruited now abun- Sauraiija. White Rose {Wehhiana^, dantly ripe). Kadsura. Sarcococca. IndigoJ'era. Spharos temma. Aiicuba. Cotoneaster. Sabia. Si/mplocos. Adamia. Myrsinea sp. GualthericE. Smilax. Holnstemma. Vaccinia. Ribes. Smilax. Rhododendrons. Jasmiiutm (white). Herbaceous plants are common, but being annuals they are comparatively backward ; the chief are — Dentaria. Androsace. Many and splendid Viola. Tiarella. Arisamas. Anemone. Chrj/sosplenium. Panax (2 herbaceous Potentilla. Ophiopogon. sp.). Fagopyrum. Coriaria. Some fine Hedychia. Paris. Fumaria. Roscoea. Trillium. Dielyira. Strcptoiirion. Euphorbia. Corydalis. EAST NEPAL AND THE SIKKIM UIMALAYA iMOUNTAIXS. 121 A leafless purple Ccelogyne ( C. Wallichii ?) is abundant, and makes a gorgeous show on the trees, as do the white-flowered leafy species. The gardens at Darjiling are ven,' gay during this month — roses, poppies, snapdragons, heartseases,] larkspurs, pinks, and lupines. Strawberries ripen, and continue in fruit for two months. The cucurbiiaceous vegetables are planted, as melons, cucumbers, squash, &c. Those planted in autumn are now pro- ducing abundantly, as peas, French beans, salads, turnips, and cabbages. Middle Zone. — In this region spring is only now established ; much less rain (one-third less) falls above 10,000 feet, in the position marked P in the woodcut, than at Darjiling. Snow occasionally sprinkles the forest, but what falls does not lie on the ground. On the other hand, the winter's snow, still abundant at 12,000 feet, is rapidly melting, and the rivers rise daily. The different pines, Abies Webbiana, Brunoniatia, and the larch flower, as do Viburnum, willow, and juniper. Very few her- baceous plants are advanced, of which the chief are a purple Dentaria, and some other Cruciferce, primroses. Anemone^ Ranunculi, a Gentiana, two large Ariscemas, a purple Saxi- fraga li!;e ciliata, Cotoneaster, Potentilla, and Podophyllum. Upper Zone. — So little snow falls here, comparatively speak- ing, that the passes even of 18,000 to 19,000 feet are open this month, but vegetation has made little progress, the soil being frozen in many places. Even the grass is not long enough to be cropped by cattle or sheep. Ju7ie. — Mean temperature (7000 ft.) 61 "2° ; of maxima 66*7°, and minima 55'8°. Extremes 71° and 51 "5°. Extremes of radia- tion—solar 126°, terrestrial 47°. Extreme differences — solar 62°, terrestrial 4*8°. Mean daily range of temperature, 11°. Mean dew-point, o9"5°; saturation 093°. Rain 26*964 inches (mean of 5 years — maximum 32-68 inches, minimum 12 inches), distributed, in 1849 (when 32*688 inches fell), over every day but 7, and every night but 3. Between sunrise and sunset 12*593 inches fell ; during the night 20*035 inches. The showers, though heavy and frequent, do not combine to form a continuous down- pour at any time, and there is a good deal of sunshine from 8 to 10 A.M., and often at sunset also. The flowering season of most of the trees at 7000 feet is now over, but many shrubs blossom, as Polygala, Xanthoxylon, Indigofera, a Magnolia with white sweet-scented globe flowers, SpircEas, Hydrangea, yellow jasmine, various AraliacecE, Neillia, Leycesteria, and shrubby Polygona ; Pyri, many and shrubby ; RosacecB generally ; some laurels and Viburna, vines. Of herbs, balsams now appear prominently, with SheploUrion, Ge- 122 CLIMATE AND VEGETATION OF rania, great-flowei'ed Aristolocliia, Parochatus, Smilacituij Convallaria, and Dispora ; some fine Scitammece, Parnassia, Poteiitilla aiiserina, Arum and Ariscemas, Monotropa, Pyrola, Pieris, yellow Craiqfurdia, Iris, Campanula, Palanophora, HahenaricB, and some curious terrestrial orchideae, as Cyrtosia. Wild brambles are abundant, and several kinds are very good. Elceagnus berries ripen. In the gardens the rains damage the unprotected flowers sadly. Cuttings are taken of rose, sweet-william, and pink. Such flowers as will blossom after the rains are now sown, as sweet- j>eas and lupines. Tulips flower, but not very well, as does the Fuclisia. Transplanting goes on activelj'. Table vegetables of all kiiids are abundant and good, but flavourless. Middle Zone. — I spent the greater part of this month above 11,000 feet, a little to the north of the position of Kinchin- junga, in well-wooded valleys, &c. The weather was uniformly cloudy, misty, and rainy ; but the showers were never excessive, and only 6 inches fell, or one-half less than at Darjiling. The trees in flower are generally of the same genera as flowered at 9000 to 10,000 feet last month, and the species are in many instances the same, as Pyri, birch, one oak, willow, a maple, holly (forming a bush) ; Abies Webhiana cones are a splendid liurple, those of the larch red brown, and of P. Smithiana green ; junipers form beriies. A wliite cherry, Loniceras, Syniplocos, and Pieris, are the chief flowering trees. Of shrubs there are other Loniceras, Potentillas, Rhododendrons, Araliacece, 2 cur- rants, willows, Andromeda, Gualtlieria. Primroses are the glories of the herbaceous vegetation, appearing in profusion, yellow, white, and purple ; beautiful anemones and ranunculi flower, with Thalictra, some Berberris, a splendid single-flowered 3Iecnopsis, several Cruciferce, Tamarix (creeping), Sibbaldice, Fritillaria, Orobunche, small Paris and Trillium, Pinguicula, Parnassia, Allium, Morina, Ophiopogon, the great Rheum, Junciis, and Luzula. Rhododendrons many. Upper Zone. — Towards the end of this month the grass is well grown in the valleys, at 13,000 to 16,000 feet, and the cattle aie driven up to the grazing grounds. A few plants flower above 15,000 feet, as Anemone, Primida, Astragalus, Par- nassia, and Picrorhiga teeta. July. — Mean temperature 61'4° ; of maxima and minima 6o'5° • — 57'3° ; extremes 70° — 56°. Extremes of radiation, solar 130°, terrest. 3'52°. Extreme differences, solar Q2°, terrest. 3'5°. Mean daily range of temperature 8°. Dew-point 60*7°. Saturation 0"97°. Rain-fall 25"336 inches (mean of 5 years, maximum 33, minimum 17-915). In 1848, 21-605 inches fell ; it rained every (ay but one, 12'22 inches per day, and 9"23o between EAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAINS. 123 sunset and sunrise, there having been 18 rainless nights, but only five occasions on which none fell between sunrise and sunset. The beautiful scarlet Buddleia at 9000 to 10,000 feet, and a fine Erythria at 6000 to 7000 feet, are the only remarkable trees I have noted as flowering during this month in the lower zone, except a Saurauja. Of shrubs, the chief are Hypcrica Deutzia, Philadelphus, Neillia, and many that flowered late in tlie previous month, together with the beautiful red rose. Herba- ceous plants succeed one another rapidly ; magnificent Balsams, CyrtandracecB, Begonias, Scitaminece, and ^schynanthus abound, with 3Ihmdus, Torrenia, Campanula, Codonopsis, Thalictra. The gigantic lily, and various terrestrial Orchidea, as Calanthe, Habenaria, Spatkoglottis, Neottia, and Serapins. Epilohia are common. Circece, Valeriana, Notochcete, tlie purple Convolvulus, white-flowered Polygona, and Cucni-hitacece begin to flower. Acorns, holly, and laurel berries are fully formed ; Lahiatce bud, as do Compositce and Urticece. In the garden there are still heartseases, lupines, sweet peas, roses, evening primroses, dalilias, sweet AYilliams, hollyhocks, mallows, snap-dragons, and marigolds. The kitclien-garden sliows radishes, cress, cabbages, squash, and other Cucurbitaceai ; French beans and peas, but sparingly ; cabbages, brocoli, and cauliflower abundant. AVeeds grow apace and keep the gardener busy. Second, or Middle Zone. — I spent much of this month at 12,000 to 16^000 feet elevation, and further north than in June. Tlie rain-fall I found reduced to little more than 6 inches ; it rained however nearly every day, three times as much falling at night as during the day. Between 10,000 and 14,000 feet vegetation has advanced during this month with marvellous rapidity. The short grass and herbage of open spots, especially at 10,000 to 12,000 feet, are replaced by a rank growth, 6 to 8 feet high, of Thalictra, tall Astragalus, grasses, and Cype- racece, Euphorhice, a superb yellow and a purple Meconopsis, each with racemes 1 to 2 feet long of blossoms as broad as the palm of the hand ; gigantic Heraclea spring up 9 feet high whilst fruiting, with twiggy Bupleura, Dipsacus, Convallarice, Dispora, and Smilacina, Ciinicifuga, Rumex, and various Compositae not yet in flower, bound together by masses of Cuscuta and Codonopsis. Amongst these grow, but more sparingly, Bala- nophora, Morina, Gerunia, large Cynoglossa, many Pedicularis, Hypericum, and Gamoplexis, together forming complete thickets of herbage. In more open places, at greater elevations, 12,000 to 13,000 feet, Cypripedium, Epipactis, and small OrchidecB are very abundant, with tufted Astragali, Lloydia (two species), 124 CLIMATE AND VEGETATION OK Other Pediculares, Triglochm, Callitriche, Veronica, Campa- iiula, Saxifraga, Draha, small Morma, Parnassia, Ehemn, T/iermopsis, a Sanssurea with bladdery bracts, Anisodinus flowers, Berberry begins to fruit, as do Pyri and Lonicera. Agriculture is little pursued at tliis elevation, Fagopyrum crops flower at 12,000 feet, and barley sown two months before is fully in ear, or, if sown in the end of May, in flower early this month. Eadishes and turnips are in leaf at 15,000 to 16,000 feet, and tlieir tubers formed. Potatoes flower. Tliird, or Upper Zone. — There is much snow still in July, even on the rearward mountains, where the perpetual snow-line is at 18,000 feet; still most of the slirubs that are found above 14,000 feet are in flower, as Spiram, Lonicera, Poteniilla, willow, juniper, berberry, and an occasional rose. Ranuncu- lacece abound. Ranunculus, Delphinum, Aconitiim, Caltha, many Astragali flower, with Corydalis, Hypecotim, Myosotis, Parnassia; many Pedicularis, Sibbaldia ; small Pri/mdce, Alsinece, and Crucifercs ; the alpine purple Meconopsis, Ma- rina, Androsaces, Picrorhiza, Nardostachys, Gymnandra, Dra- cocephnlum, Veronica, Seda, Cassiope, and Menziesia. The single-spiked Carices and Poce flower, Festuca, Aira, Hiero- chloe, Stipa. In Tibetan regions a nettle abounds at upwards of 16,000 feet, and some ArtemisicB are the only early Com- positae in flower. August.— 'MediW temperature (7000 feet) 61'7° ; of maxima 66-1°, and minima 57-4° ; of daily range 8-7°. Extremes 70° and 54-5° ; of radiation— solar 133°, terrestrial 50°. Extreme differences — solar 62°, terrestrial 3*5°. Mean dew-point 60-4° ; saturation 0-97. Rain 29*454 inches (means of 4 years 33-320 and 24-510 inches). In 1849 26-811 inches fell, and it rained every day but one, 10-802 inches falling after sunrise, and 16 after sunset. In the interior, on the other hand, at the same elevation, I experienced only 12*45 inches of rain, of which 8-29 fell in the night, and 4-16 during day. It rained, however, more or less nearly every day. Vegetation in the lower region is at its fullest vigour. The common bracken {Pteris aquilina'i) covers the ground, with a yellow Cucurhitacea. Many annuals that flowered in May and June are passing to seed, as Cyrtandracece, balsams, and bego- nias, but still many species are in flower. Umhelliferfs, which are rare below 9000 feet, flower, together with Ane7none viti- folia, various Hedychia, some very magnificent. Sparganium blossoms, and Colquhounia, the small-flowered Neillia, Cero- pegias, Cuscuta, many Cucurhitacea;, especially Trichosanthes, tree Araliacecc, the sweet Buddleia, Ophelia, Clematis, Tri- cyrtis, Passijiora, Myrsine, and Emhelia, yellow honeysuckle, KAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAINS. 125 Xanthoxylon, Hypericum, Osbeckia ; a few thistles commence flowering, with gnaphaloid Composite', but not so freely or fully as Eupatorium, blue CichoracecB, Myriactis, Callinieris, two Artemisias, Picris, Inula, Doronicum, and Mulgedium. In open places at 8000 feet Euphrasia, Drosera peltata, Neottia (Bstivalis, Dijjsacus, Halenia, and Erigerons flower. In tlie kitchen-garden potatoes are planted with manure, and towards the end of the month the haulms of the early sorts wither, and the roots are stored. Table vegetables are abun- dant, with legumes of all kinds, turnips, radishes, carrots, lettuce, all varieties of vegetable marrows, squash, cucumbers, and asparagus, the latter generally small and woody. In the flower-garden are dahlias, marigolds, sunflowers, China roses, lupines, mignonette, larkspurs, rose-campions, Oenotheras, hearts- ease, all thriving tolerably if protected from the rain, but it is better to keep them back till the following month. There is little native cultivation carried on. Rice and other cerealia are in ear above 7000 feet, and maize is in flower just below that. Animal life swarms in this month, especially insects. Cicadas and glow-worms ascend above 8000 feet. Libellulce, Tipulce, Cynthia cardui, and Papilio Machaon are very frequent at 6000 to 10,000 feet. Mosquitoes in myriads and countless leeches, with sandflies, swarm at 6000, and ascend to 8000 feet, the leeches and sandflies to 12,000. Swampy places become feverish even at 6000 feet. Second, or Middle Region. — Above 9000 feet vegetation is also in its prime, from the abundance of Compositce which adorn the skirts of the woods and open places, especially beautiful senecios, thistles, Mulgedium, Aplotaxis, Dolomiaa, Ligu- laria, and Saussurea, Callimeris and abundance of Erigeron, Doronicum, Clematis blossoms freely. Gentians, Halenia, Ophelia, &c., are all in bloom, with the most of the Umhel- lifera-. Saxifrages form masses of golden blossoms at 12,000 to 13,000 feet, mixed with Cyananthus, Codonopsis, Scrophu- laria, Polygona, Fumaria, and Corydalis, Oxyria, Primula denticulatu. Salvia, Delphinia, tall aconites, terrestrial Orchi- dece, Lilium Thomsoni, Verbascum, and many other European genera. Third, or Arctic Zone. — Some beautiful primulas are still only in flower, near the snow, at 15,000 feet, with many species of Corydalis, Nardostachys, Chrysosplenium, Menziesia, Sedu, Saussurea, Parnassia, yellow Drabas, and Androsaceee, at the southern passes, which, being in a more rainy climate, are backwarder. In the northern or drier parts, again, Artemisice appear, with Delphinium Brunonis, various Cyananthi, Vero- 126 CLIMATE A^'D VEGETATION OF nisa, Kvenigia, 6 potentillas, Anaphalis, Serratula, and many grasses, caiices, and Junci. September. — Mean temperature (7000 feet) 60° ; of maxima 64*7, and minima 55*2 ; of daily range 9'5°. Sunic thermo- meter 60°. Extremes of temperature 7U° and 51-5° ; of radiat- ing- thermometers — solar 142°, terrestrial 475°. Extreme dif- ferences— solar 70°, terrestrial 10°. Mean dew-point 58.5° ; saturation 0*95°. Rain 15*762 inches (mean of four years 20-375 and 13,410). In 1849 15-675 inches fell, 3-621 by day, and 12-054 by night. It rained all the month except on 5 days, but most frequently at night. The first fortnight of this month is usually a continuation of the August humid weather, when it holds up for a week or so previous to the equinox, which is ushered in by violent electric disturbances and heavy gales. The most prominent botanical feature of the month is the abundance of LahiatcE, especially Plectranthi, ElsJiolsia, Cra- niotome, Colquhounia, Prunella, Ajitga, Scutellaria, Nepeta, and Melissa ; and graphaloid compositge, especially species of Anaphalis, Mhiten the ground in some places. Oshechia is in full bloom, with white and shrubby polygonums. Many Urticece flower, but they are insignificant green plants. March and April flowering species are generally in seed. Acanthaceee, of which there are very few, flower. In the garden the vegetables are, besides those of August, more cruciferce, as kohl-rabi and savoys, with tomatoes and capsicums. Peas and beans are sowed for early crops, with cabbage, turnip, beet, radishes, and spring crops of all kinds. Peaches redden and fall oflT the trees without ripening. Straw- berry-beds are cleaned and ruimers planted ; rose-cuttings made. Rice and other cerealia are cut at 4500 feet, but not higher. Second, or Middle Zone. — I passed the latter part of August and beginning of this month at 11,000 feet, considerably north of Kiiichinjunga, in a very moist valley, with patches of snow in gulleys at 12,000 feet, where, however, the rain-fall was less than half that at Darjiling. From the 8th to the end of the month I camped at 15,400 feet, and experienced only 1-67 inches, whilst 9-993 fell at Darjiling. A good deal of this m as in the form of snow, which lay for several days at 16,000 feet, as early as the 9th. At the equinox the snow lay three days around my tent, but melted again. In the more southern parts of Sikkim (in the position of P on the woodcut) the September snow-fall sometimes lies till the following April or May. The weather was constantly misty and foggy at my position, but was always clear though cloudy when I went into Tibet. U'liis is a fruiting month everywhere above 13,000 feet; the barley and Fagopyrum crops are cut, and turnips and radishes gathered ; EAST NEPAL AND THE SIKKIM HlilALAYA MOUNTAINS. 127 the cattle are driven down to 12,000 feet early in the month, and to 10,000 feet towards the end. Dandelion, Erigeron, and other compositee are still in full flower. Fourth, or Upper Zone, above 15,000 feet. — Many plants continue in flower early in the month and to beyond the middle, as beautiful Cyananthi, Gentians, Elsholsia, Calthn, Taraxa- nem, Prunella, curious LactucecB, Saussurece, and Serralulas, Leontopodium, and other Gnaphaloid compositse. Small Poly- gona, Primulce, and indeed all June and July flowering plants, ripen their seeds. By the 21st vegetation may be said to be at an end, the grasses change colour, and severe frosts set in. Birds migrate south, and the Hoopoe and various small birds are occasional visitants on their passage to warmer climates. October. — Mean temperature (7000 feet) 58^ — of maxima 66'0°, minima 49"5° ; daily range 17°; sunk thermometer 59° ; extremes of temperature 68° and 43o^ ; of radiating thermome- ters— solar 133°, terrestrial 32°; extreme differences from temperature of air — solar 65°, terrestrial 12°. Mean dew-point 52*5° ; saturation 9"88. Kain-fall 8'66 inches (mean of four years 17*964 and 5"50). Tliis is one of the most variable months in the year as regards the distribution of both heat and moisture. Fine weather almost invariably follows the equinoxial gales, and sometimes lasts. October has loeen described to me as a glorious, cloudless month, without a drop of rain. In 1848 there was more bad weather than good, with heavy squalls, thunder and lightning, and nearly 18 inches of rain fell. In 1849, again, very little rain indeed fell, but the month was so uniformly fog'jfy and damp, that the rains were not considered over till November ; yet during twenty days no rain fell at all. The same irregularity marks this season at all elevations, and I experienced more rain at 13,000 feet, in an almost Tibetan climate, than fell at Darjiling, owing probably to the condensa- tion of the southerly wind over the September snow-fall, vvhich had already lowered the snow-line in some parts of Sikkim. In the lower zone tliere are still plants to flower, as Prinsepiay the beautiful blue Craivfurdia, Eleagnus, and Balanophora pohjandra. Various species of Clematis also flower, with Ca- mellia, Eurya, Cuscuta, Syynplocos, Prunus, Wightia, a late- flowering Michelia, Aplotaxis, the superb Luculia gratissitna, fragrant Olea, Bucklandia, Eleagnus, and many parasitical OrchidecE. The apple and other wild fruits ripen. In the garden the early frosts are apt to do injury ; potatoes should be all housed ; celery is planted out in trenches ; cabbages and kohl-rabi in drills. The garden should be all cleaned and weeded for planting spring vegetables before the end of the month. 128 CLIMATE AND VEGETATION OF The natives gather in all crops between 6000 and 8000 feet this month, including the various millets, which yield 200 to 400 fold, and the unirrigated rice grown in slopes, and producing 80 fold on the average. Second, or 3Iiddle Zone. — Above 14,000 feet the scene is more wintry than autumnal, but below that many Compositce and UinbellifercE continue in flower, and some in fruit ; the Coniferce all have fully formed cones ; some Clematis flower with Prin- sepia, and blue Crawfurdia and the nut. The larch leaves turn yellow and then red previous to dropping. Belts of scarlet girdle the forests from the abundance of berberries, whose leaves change colour. The bircli turns golden yellow, Pyri and maples red and yellow, whilst the Abies Webbiana and junipers are still black, the grass brown, rhododendrons a briglit verdegris green. Of the latter some species throw out a few flowers, but most are in seed, as are wild currants, cherries, berberries, apples, hips, and Stauntonia, which latter affords the best wild fruit of this region and that below it, except Rubi. November. — Mean temperature (7000 feet) 50° — of maxima 56'5°, minima 43*5°: daily range 13°. Sunk thermometer 54°. Extremes of temperature 63° and 38° ; of radiating thermometers, — solar 123°, terrest. 30°: extreme difference from temperature of air — solar 68°, terrest. 12°. Mean dew-point 46*5° ; satura- tion 0-89°. Rain-fall 0-4°. This is the least rainy month of the year, sometimes no rain falls, and it seldom exceeds a few tenths of an inch. Drought is sometimes experienced, with a bright clear sun by day and sharp frost at night. The sun's rays are very powerful, considering how low the temperature is, but the air is bracing and pleasant, like an English April. The Bucklandia flowers in this month at 6000 to 7000 feet, a magnificent tree as regards form and foliage ; Wightia, a scandent Bignoniaceous tree, also blossoms profusely, bearing no leaves, and forming immense masses of red in the forest ; Pittosporum blooms, and a Prunus like Padus, whose leaves are excellent fodder for cattle. Alder is in catkin, and the yel- low Daphne Gardneri, a very beautiful plant, scents the air ; nettles flower profusely, and Cuscuta, witli the great shrubby Teucrium. All crops are now housed, and wheat and barley sown at 9000 feet to be reaped in May. In the upper regions the snow-line tlescends to 14,000 feet. December. — Mean temperature (7000 feet), 43° ; of maxima 51-6°, and minima 34*9°; daily range 16*7°; sunk thermometer 48°. Extremes of temperature 56° and 32*5° ; of radiating thermometers — solar 108°, terrestrial 26°. Extreme differences from temperature of air — solar 77*2°, terrestrial 10°. Mean dew-point 30° ; saturation 0-61°. Rain-fall 0*45. This month EAST NEPAL AND THE SIKKIM HIMALAYA MOUNTAINS. 129 is sometimes very dry; it was unusually so in 1837, when Dr. Chapman's register was ke^it: his reduced wet bulb obser%a- tions are those from which I have worked the dew-points. Hoar frost is of almost nightly occurrence in December, but the cold is never extreme. About Christmas a storm is experienced, and a great quantity of snow falls in the upper regions, at as low elevations as 9000 feet, where I have seen 3 feet : much of this melts, however, owing to the warmth of the soil. January. — Mean temperature (7000 feet) 40° ; of maxima 47'2°, and minima 32-8°; daily range 14-4°; sunk thermo- meter 45°. Extremes of temperature 56° and 29° ; of radiating thermometers — solar 119°, terrestrial 16°. Extreme differences from temperature of air — solar 72°, terrestrial 12*7°; mean dew-point 34*3°; saturation 0-84°. Kain-fall 1-718 inches; mean of three years 0'30 and 4*27. January is generally a stormy month, with bitterly cold, often violent winds, hail, sleet, and sometimes snow at Darjiling, and as low as 6000 feet, never lying beyond a few hours at the latter elevation, and it is rare for 3 inches to remain as many days at 7000 feet. Much snow falls about the middle of the month in the upper regions, the ground being covered several feet deep at 13,000 feet, and the snow-line is lowered to about that elevation, and does not recede from that till April or May. I found the soil at this elevation frozen for 16 inches, but warm below that, and as high as 34*5° at less tlian 3 feet deep. February. — Mean temperature (7000 feet) 42-1° ; of maxima 50°, and minima 34'2° ; daily range 15-8° ; sunk thermometer 47°. Extremes of temperature 57° and 25*5°; of radiatino- thermometers — solar 124*0°, terrestrial 23*°. Extreme differ- ences from temperature of air — solar 78°, terrestrial 15-3°. Mean dew-point 36*7°; saturation 0-85°. Eain-fall 0916; mean of three years 2-047. This is also a stormy and cold month, with a good deal of thunder and lightning, hail, and sometimes snow. Turnips, car- rots, beet, and cabbage are the ciiief garden vegetables ; peas blossom freely in spite of the weather ; tender plants are pro- tected by matting ; artichokes and rhubarb are manured ; lupines, marigolds, and stocks are still in flower. Snow that falls at 11,000 and 12,000 feet remains till April : there are no plants of any consequence in flower above 6000 feet. I append a meteorological register of the separate months for convenience of reference, but at the same time must remind the reader that it does not pi-etend to strict accuracy. It is founded upon observations made at Darjiling by Dr. Chapman in the year 1837, for temperature and wet bulb only ; the other data and some modifications of the above are supplied from a very careful 130 CLIMATE AND VEGETATION OF collection of a nuiltitude of observations of my own. The means of the month are taken by meaning the daily maxima and minima, which I tliink gives too liigh a result. Those for ter- restrial and nocturnal radiation are accurate as far as they go, that is to say. tiiey are absolute temperatures taken by myself, whicii may, I believe, be recorded in any year, but nuuh liigiier are no doubt often to be obtained. The dew-points and satura- tions are generally calculated from the mean of two day ob- servations (10 A.M. and 4 p.m.) of the wet bulb tiiermometer, toiJfether with the minimum, or are taken from observations of Daniell's hygrometer. The dew-point and temperature are as- sumed to coincide onlj^ at the hour of minimum temperature ; but as the}^ do coincide for, on the average, 10 hours of every 24. tins method obviously gives too low a dew-point. On the other hand, the wet bulb observations, or hysrometer, were never taken at the hours of greatest dryness : and as I find the mean of the temperatures of 10 a.m., 4 p.m., and the minimum to coin- cide within a few tenths with the mean temperature of the whole year, I assume that the mean of the wet bulb observations of the same hours will give a sutHciently accurate approach to that of the 24 hours. The climate of Darjiling station has been in some degree altered by extensive clearances of forest, which render it more variable, more exposed to night frosts and strong sun, and to drought, the drying up of small streams being one direct consequence. My own observations were taken at Mr. Hodgson's house, elevated 7450 feet, the position of which I have indicated at p. 2 of this volume (in a note), where the dift'erences of climate due to local causes are sufficiently indicated to show that in no two spots could similar meteorological results be ob- tained. At my station, for instance, tlie uniformity of tempera- ture and humidity is infinitely more remarkable than at Dr. Chapman's, possibly from my guarding more effectually against radiation, and from the greater forest about Mr. Hodgson's house. I have not, however, ventured to interfere with the temperature columns on this account. Such as they are, I believe they afford amply sufficient data for the horticulturist who is anxious to exert his skill and ingenuity in the cultivation of Himalayan plants in general, and especially of Sikkim ones, though they will little avail him except he be previously master of the climate of England, for which purpose I would most strongly urge the study of Mr. Daniell's essay before alluded to, and the many papers in this .Journal and elsewhere of Mr. Thompson, of the Horticultural Society's Gardens, which contain a vast amount of valuable matter, carefully collected and extremely well arranged.

VII. — On Grape Mildew. By Hugo v. Mohl. [Translated from the Botanische Zeitung, Jan. 2, 1852.] The attention of the readers of the Botanische Zeitung has frequently been called to the disease which has attacked the vines for some years in the west of Europe, and has been ex- tremely injurious to tliem. Since this epidemic has passed over the boundaries of Germany, and the history of its previous course gives ground for fearing that it may spread widely amongst us next year, some more particular account, which I am enabled to give from observations made last autumn in Switzerland, may not be vmacceptable. How far it deserves to be called a new disease may be left undecided. Even supposing it to have appeared from time to time in isolated spots, it must have been in a very trifling degree, since it did not excite the attention of the cultivators of vine- yards, and the fungus attendant on it was imknown to botanists. It was calculated to attract the greater interest last year because, after its first appearance at Margate (see Bot. Zeit., 1848, p. 376), it gradually spread into France, where it appeared at Versailles, in 1848 (see Bouchardat in Comp. Rend, xxxiii. p. 145), the next year, to some extent, at Paris, and finally, in ISol, reached the south of France, at the same time rapidly travelling the whole length of Italy from tlie coast of Liguria to Naples, then, as autumn approached, taking a retrograde course through the Tyrol as far as Botzen, overrunning nearly the whole of Switzerland northwards to Winterthur, and, at last, trespassing on certain isolated points of Germany at the Hard- gebirge, in Baden at Salem, and in Wiirtemburg at Stuttgart and Cannstatf. On its first appearance in England, as also at Versailles, Paris, and Grenoble, it seems to have been confined to the vines in hothouses, and from thence to have spread to those on walls, and, finally, to the vineyards. In districts where grapes are cultivated exclusively in the open air, the disease in 1851, in many places which I visited, as, for instance, in great part of Switzerland and AViirtemburg, attacked those vines which were grown on walls, and, where it had attacked the vineyards, the bunches on the walls suffered far more than those on vines in the open field ; and I was convinced that, in particular spots, where the malady was at present much confined, it had passed from the trellises to the neighbouring vineyards. It reached the greatest heio:ht on those trellises which stand vinder the wide-spreading roofs of the Swiss houses, and by which they are protected from the rain. ON GRAPE MILDEW, 133 From its very first appearance it was observed to be constantly attended by a {angus {Oidium Tuckeri, Berk.). This fungus resembles, to the naked eye, a white, mealy coat, which, accord- ing to the virulence of the disease, forms a scarcely visible powder, or a tolerably thick crust. In slight cases the fungus arises only in certain places of the plant, and, without any defi- nite rule, sometimes on the bark of the two-year-old shoots, sometimes on tiie leaves, sometimes on the stalk of the bunches, or on the berries themselves, but on such parts only as are covered with a living cuticle, and never on the dead bark of the older branches. In extreme cases the fungus covers every part which has developed itself in the course of the summer so thickly that at the distance of twenty paces the vine is at once known to be diseased. A question has arisen in various quarters whether this fungus is a peculiar species, and confined to the vine ; Marie, for instance (Comp. Rend. xxxi. p. 312, 454), Guerin-Meneville, and Bal- samo Crivelli (1. c. xxxiii. p. 295) assert that the same fungus grows on many other plants, and that Oidium Tuckeri is iden- tical with Old. leucoconium. Since it depends so much on the peculiar views of individuals, whether two allied forms are consi- dered as varieties or distinct species,* I shall not consider tliis point more narrowly, j though the difference between Oidium Tuckcin, with its clavate incrassated threads surmounted by only one or two spores, and O. leucoconium, whose threads produce a long row of spores, appears so striking-, that we must necessarily allow the existence of a specific difference. The question seems to me far more important whether Oidium Tuckeri is cajmble of living on other plants besides the vine. If this were the case, it would be probable that it might spread from diseased vines to neighbouring plants. This, however, seems decidedly not to be the case ;:]: at least, notwithstanding the most careful examina- tion in a garden where plants of the most different families stood close to highly diseased vines, I could not find a trace of the fungus on any plant whatever ; it did not attack even Am- pelopsis quiiiquefolia, although the boughs were intertwined * No great stress can be laid on the size of the spores, since in those of Oidium Tuckeri, -which I figured by means of Sommering's apparatus, the major axis varied from jL to ^"', the minor axis from ^ij to jig'". t It is very true that in fungi the reproductive organs vary greatly in size ; but if the mean in every case be ascertainetl, it will be found available for the distinction of species. To take a familiar example, peas may be found in any undressed sample no larger than tares, and yet it may be safely asserted that peas have much larger seeds than tares. — Traiisl.

Wiiether the plant is capable of attacking' American vines I am not able to say, since in the only vineyard in which I saw a quantity of these vines, all were healthy, a circumstance which may, how- ever, be accidental, since the vineyard itself was only slightly infested wi(h the disease. As in so many other cases of fungi which accompany disease, so in tlie grape mildew, the question has arisen wiiether the fungus is the cause or the consequence of the malady ; and so, also, as in many analogous cases, the original ground of the evil has been attributed to insects, as, for instance, by Robineau- Desvoidy (Conip. Rend, xxxiii. p, 343). This latter view seems to me to be decidedly wrong. I am very far from wishing to intimate that Robineau's observation of the presence of an Acm'its on diseased vines is false, though, after the most careful microscopical observations of many diseased vines, in all stages of the malady, and in different places, I have been unable to detect any insect, and therefore can only attribute their occur- rence, as observed by M. Robineau, to mere accident. A far more difficult question to answer is that, wiiether the fungus is the cause or consequence of the disease. Were the fimgus an entophyte, did it arise from a visible demonstrable alteration of the contents of the cells, did it break out from within the plant to its external surface, the latter position might be considered as proved.* Tlie contrary, however, of all these things is the case. Not the slightest trace can be discovered of any disease of the vine anterior to the appearance of the fungus, which creeps over the cuticle of the plant, does not protrude into its tissues, and much lessf arises within previous to bursting forth into the free air. These circumstances make it probable that the fungus first affects the plant on which it grows by decomposing the juices of the superficial cells, and impeding their growth in the same way in which Achlya proUfera injures the aquatic animals on which it grows, and as Merulius destruc- * Oldinm leucoconium is an entophyte, exactly as Botrytis infestans and the group of allied species which grow on green leaves ai-e eutophytes. The probability therefore is pritnu facie that O. Tuckeri is an entophyte. — yyansl. t It is figured in the ' Gardener's Chronicle ' as making its way, like other Oidia, through the stomata. Le'veillc, however, like Mohl, denies that this is the case ; and Duchartre asserts truly tliat there are no stomata (or at least extremely few) on the upper surface of the vine leaves, on M'hich the fungus grows according to Continental authorities. At Margate, how- ever, it was more abundant on tlie under than on the upper surface of the leaves. A re-examination of the matter must be deferred to the summer, as it is impossible to make out anything satisfactory from dried specimens. Indeed, like many other moulds, it is very diflBcult to preserve in the Herba- rium, on account of the ravages of mites. — Transl. ON GEAPE MILDEW. 135 tor produces decay in dead wood. Many experiments also seem to prove that the cause of the disease is to be found in the fungus, according- to which the fiirtlier diffusion of the evil is greatly repressed by the removal of the first affected shoots on a wall, the destruction of the fungus through washing, &c.* The indisputably contagious character of the disease is also explained only by the fact that the fungus causes the malady, for it is easily imagined how the lightest breeze may carry the innu- merable quantity of spores which it produces, and which are only Tu-o"'" "^ length, from the diseased to the sound vines. The appearances which the diseased vines present are as fol- lows. The spots on the green bark of this year's shoots on which the fungus has begun to vegetate are discernible by a faint cloud in their green tint before the fungus itself is visible to the naked eye. The fungus consists at this time of minute extremely delicate threads, visible only through a good lens, resembling those of a spider, which creep on the surface of the cuticle, forming an irregular web. The bark has assumed in the spots which are attacked, frequently not exceeding 1'" in diameter, a somewhat deeper tint ; these spots soon increase in diameter as the disease spreads, become confluent, and change, in consequence of the death of the superficial cells, into a choco- late brown. Microscopic observations show that the depravation of the juices which produces this change of colour, and tlie death of the diseased cells, is confined to tlie most superficial strata, while those which lie deeper, as well as the wood, remain per- fectly sound. Under these circumstances the malady, as far as it attacks the branches, seems a very unimportant evil, and there is no danger of the death of the vines which are attacked, inas- much as the external coats of the bark must, in the natui'al course of things, be dried up in the ensuing autumn and winter, and tlirown off during the next year. The fungus exercises a still smaller influence on the leaves than on the branches ; at least I could not remark, even in those vines which were thickly covered with the fungus to the very tips of the shoots, that the vegetation of the leaves was really affected. As regards the fruit the case is far otherwise. Here also only the extreme layer of cells at first suffers under the attack, while the inner parts of the fruit, as far, at least, as may be concluded from microscopic observation, remain perfect. The appearances which the affected berries exhibit differ much, according to the * I could uot institute the experimentum crncis of banging diseased bunches ■which I bad brought to Tubingen, where the malady has uot yet intruded, on untainted vines, with the view of proving whether it could not be com- municated by contagion, because I would not subject myself to the respon- sibility of contributing to spread the evil in a wine district. L 2 136 ON GEAPE MILDEW, time which has elapsed since they were infested, the greater or less vigour of the fungus, «fec. When the fruit is sharply attacked, and at a time when it has arrived at about half its growth, or when it is scarcely so large, since the outer diseased skin cannot keep up with the expansion of the juicy parenchym, it splits longitudinally into many lobes, so that the seeds, wiiich are more or less perfectly developed, are exposed, as in the rup- tured capsvde of an Euonymus. These fissured berries seem, under all circumstances, incapable of further development ; they remain small, although they hang on the vine till late in the autumn, and seem at last to dry up or rot ; at least I saw in none any symptoms of becoming ripe. On tlie contrary, if the fruit is attacked towards autumn, when it is already much advanced in its development, the influence of the fungus is too weak to prevent the production of ripe, perfect, normal fruit, even when the stalks of the berries are thickly overrun with its tlireads. Between these two extreme cases a number of inter- mediate conditions naturally occur, in which the berries do not crack, but are arrested in their growth, and never ripen or become profitable. The question whether the use of diseased grapes has any noxious consequences, seems not to be decided. While, on the one side, a string of examples from French papers is brought forward in the Reforme Agricole, according to wliich diseased grapes are injurious, producing colic and vomiting, express experiments to a contrary eflfect have been communicated to me in Lausanne. Probability is in favour of the latter opinion, since the extent to which the malady has lately reached in France could not fail to have aflTorded a number of well-esta- blished examples, if the diseased grapes were really injurious, for they were frequently eaten by children. It is a natural question, what will be the condition of the dis- ease in future ; is it transitory, brought on and favoured only by accidental and temporary circumstances, or is it a durable evil, and what remedy, in this case, can be administered for the warding off or diminution of the malady? We are treading here on dangerous ground, for it is notorious how little, for the most part, in epidemic diseases, science is in a condition to answer such questions, and the potato murrain affords a lamentable instance amongst vegetable epidemics how little the numerous solutions of the difficulty, and these frequently given with no less confidence than imperfect knowledge, serve for the removal of the evil. The question as to the future condition of the malady, whether it will vanish or extend step by step to the districts which at present are uninfected, is, from the very nature of the case, per- ON GRAPE MILDEW. 137 fectly incapable of answer. The prospects afforded by its pre- vious history are by no means comfortable. We have to contend with an enemy against which, as regards its diffusion, we are perfectly powerless, since every breeze may bring thousands of its minute microscopic germs from an infected district to one which is at present untainted. Nor less is any notion of tlie destruction of the fungus on the diseased vines, by washing, fumigation, &c., in places where vines are extensively cultivated, completely out of the question. Under these circumstances there reniains only the by no means powerful consolation that, as in analogous diseases produced by other fungi, even though it may not entirely vanish, it may be expected to be at all widely extended, and, consequently, decidedly injurious, only in certain years. A remedy is the more difficult, or rather the more im- possible, because it relates to a woody perennial plant, and there- fore a multitude of variations in the mode of culture which are available in annual plants, as different ways of planting, the choice of a favourable site, rotations of cropping, &c., are clearly inapplicable. It appears also that all such remedies as depend on variations of culture, even were they more easily applicable to the vine, would not be crowned with much success, since, at least as far as my own experience goes, no particular rules are deducible from the condition of diseased vineyards, according to which the occurrence of the evil is regulated as regards the exposure towards a particular quarter of the heavens, the geological nature of the subsoil, the lower or higher training of the plants, the age of the vineyard, the circumstance whether it had been recently planted on virgin soil, or was of the growth of many centuries, &c., since none of these points seem to have the slightest influence, and only in particular spots, a low situ- ation and the moisture of the soil, appear to be favourable. Al- though particular kinds of vines, as the crowfoot (Trollinger) and muscatels, suffer extremely, this is but a proportional difference, since in other places sorts of the most various nature were attacked ; and even should experience clearly prove the especial tendency of particular varieties to contract the infection, this point could scarcely induce any great alteration in the cultivation of the vine, as the choice of sorts depends upon so many other circumstances. At least for the present what is possible to be done in the way of alleviation must be confined to culture on a small scale in con- servatories or on walls, since the small quantity of vines Avhich are cultivated in such situations admit of some special treatment. These situations are moreover, as was remarked above, the most perilous, because they afford the most favourable ground for the malady, and form the centre from which it extends to the vine- 138 METEOROLOGICAL OBSERVATIONS yards, for which it is so much the more dangerous, since the artificially accelerated development of the vine permits its occur- rence some months earlier than in the open air, and the disease is in a condition to attack the bunches at a mucli younger stage of growtli. It is a great question whether, now that the disease is widely spread, any benefit would be derived from preventing the artificial growth of grapes, as has been proposed, on one side, even supposing it were, or could be, put in practice ; on the other hand, there is no doubt that tiie owners of vines wliich grow in conservatories or on walls can use remedies against the malady when appearing in such situations. It seems at least, after the experiments made in England and France, to admit of no doubt that the removal of the parts first diseased, and the washing with solutions of lime, sulphuret of lime, alum, soap, &c., besides fumigation with tobacco smoke, and dusting with sulphur, are attended with advantage.

January, — The weather was in general remarkably fine for the period of the season, and operations in the open air were carried on with less interruption than is usually experienced in the winter months. Although the quantity of rain amounted to nearly double the average for the month, yet it mostly fell in the nights ; the days were often exceedingly fine. The wind was from north-east one day, and from west two daj's ; in all the rest of the month it came from the warmer quarters of soutli, south- east, and south-west, and owing to this the mean temperature was fully 2° above the average. February. — The day temperature of this month was equal to the average, but that of the nights was 3^° colder than usual. Tlie night temperatures averaged 4° lower than those of the preceding month. The barometer stood above the average height. The quantity of rain was less than an inch, or little more than half the usual quantity. Some sleet fell on the 27th ; but throughout the month the ground was not at any time whitened by snow. On the whole the weather was very favourable for all out-door operations. March. — The first week was fine ; but from the 9th to the end of the month there were only six days in which rain did not fall. The amount of rain was fully 3^ inches, or upwards of 2 inches above the average. The bai'ometer was generally low during the last three weeks, and remarkably so on the evening of the 22nd. Westerly winds were prevalent. The average mean tem- perature was nearly maintained. The morning of the 14th was frosty with slight fog ; heavy clouds formed during the day ; the evening was hazy, and at night nearly 1 inch of rain fell. A mock-sun was observed between 6 and 7 a.m. on the 29th ; the forenoon proved boisterous, showery, with sunny intervals ; and one-third of an inch of rain fell between 8 a.m. and 1 p.m. April. — The amount of rain was exactly equal to the average. The mean temperature was 2|° below the average, and tiiis may be attributed to the prevalence of north, north-east, and north-west winds. Fourteen nights were more or less frosty. Peaches and nectarines on walls suffered much, especially in gardens where no protection was afforded. In the Society's Garden fair crops of these fruits were saved by means of coping- boards, projecting about 9 inches. The last week of the month was very inclement. On the 27th there Mas a hail-shower be- tween 5 and 6 p.m. ; the stones were large, but not very hard ; lightning was seen in the evening. On the afternoon of the 29th thunder was heard, and soon after large hail began to fall ; the 140 METEOROLOGICAL OBSERVATIONS stones were short-pyriforni, and in substance resembled compact snow. On the 30tli there were also hail-showers occasionally during- the day. May. — Tliis month was generally cold and windy. The mean temperature of the days was only lf° below the average of the days in May, but the niean of tlie night temperatures was 4° colder than the average. The first four nights were frosty. Pears were then generally out of bloom, and a plentiful crop of young fruit had set, notwithstanding the previous cold nights, even as much as 7° below freezing, on the 26th and 27th of the preceding month. But the trees had not then been much excited by warm weather. They became, however, very much so in consequence of a warm south v/ind on the 8th, 9th, and 10th of the present month. On the latter of these days tlie thermometer rose to 70'^ in the shade. The sap was in rapid motion towards the young fruit, when it was suddenly checked by 5° of frost on the night of the 14th. The flow of sap appeared to have been in consequence diverted from the fruit, and afterwards appro- priated by the foliage. -At all events most of the former became yellow in a few days, and dropped, after it had endured, 17 days earlier, 2° more of frost, with much less foliage to shelter it, June. — The mean temperature was about 1^° below the ave- rage. The quantity of rain was nearly half an inch less than the usual amount; none fell after the 18th; and from this time to the end of the month the days were generally very hot. Occa- sionally, however, the nights were comparatively cold. On that of the 23rd the thermometer was within 3° of freezing, probably the effect of a brisk north-west wind on the 22nd. The 5th, 8th, and 1 6th were boisterous. July. — Upwards of 1^ inch above the usual quantity of rain fell in this month ; yet there were many fine days, for nearly half the amount of rain fell on the 1st and 23rd, The morning of the 1st was hazy and mild ; several peals of thunder were heard ; and again about 8 p,m,, lightning being then vivid, with rain falling in torrents. This rain, it may be remarked, and also that of the 23rd, came in the train of east winds, and not from south-west, as heavy and continued summer rains generally do. The mean temperature of the month was nearly 3° below the average. August. — The mean temperature of the month was folly equal to the average. During the first three weeks the weather was, on the whole, exceedingly fine, with scarcely any rain excepting on the l7th. The barometer stood high throughout the month, altliough south-west winds were prevalent. The day of the 27th was fine ; but during the night a greater depth of rain fell than in any 24 hours of the preceding 26 years, at least in this MADE IN THE GARDEN OF THE SOCIETY. 141 locality. Before morning 1 inch ^^ had fallen. The 29th was showery, with hail between 1 and 3 p.m. On the 30th the tem- perature at night fell to 35°, and the radiating thermometer indicated as low as the freezing point. September. — The weather througiiout the iBonth was almost uninterruptedly fine. Kain fell during the day on the 25th and 30th only ; and altogether the quantity was very limited, scarcely amounting to half an inch. The barometer stood remarkably hio-h ; the height of the mercurial columu was never under 30 inches from the beginning of the month up to the 20th. The mean temperature was 2° below the average, owing solely to the coldness of the nights, for the mean temperature of the days was not lower than usual. Frost occurred as early as the 9tli, and some leaves of scarlet-runners and gourds were then blackened. On the 28th the common thermometer indicated 2° below freez- ing, and the radiating one 4° below that point. North-east winds were remarkably prevalent. October. — The mean temperature of the month was about | of a degree above the average. The depth of rain was about 2 inches, fully half an inch less than the average. The ground was previously verj^ dry, and planting out was retarded in con- sequence. The quantity of rain in this month was sufficient to moisten the soil for this purpose ; but it did not penetrate to the lower roots of trees and shrubs ; for it was found that the soil under these still remained very dry. November. — This was the coldest November that has been experienced for the last 26 years at least. The mean tem- perature was upwards of 7° below the average. 23 nights were more or less frosty. On the night of the 18th the common thermometer indicated 16° below freezing, and the radiating one as many as 21° below that point. The wind came chiefly from cold quarters — from north 10 days, north-east 4 days, and north-west 6 days. The amount of rain was very limited, being little more than half an inch. "With the exception of that on the 23rd, none fell after the 12th. December. — The mean temperature of this month was nearly equal to that of December deduced from the average of 26 years' observations, and it was 3° above that of the preceding month. The amount of rain was much below the usual quantity. With the exception of a very little on the 5th and 16th, none fell from the beginning of the month till the 19th. Reckoning from this date, and as far back as the 9th of the preceding month, there is a period of 40 days almost without rain. The barometer was unusually high. 142 OBSERVATIONS MADE IN TlIE GARDEN OF THE SOCIETY. Geothermometrical Ohservations. Temperature Temperature Monthly Day OF THE Earth. Day OF THE Air.

(Communicated March 4, 1852.) That many plants, which pass uninjured through the ordinary severity of our winters, are often seriously damaged by a few degrees of frost in spring is a fact well known to all who pay the least attention to the cultivation of hardy plants ; and the causes, too, are equally well understood. In winter the plant is at rest ; its vegetative powers are in a comparatively dormant state. The tissues are solidified and more deficient in tluids than at any other season, and a combination of circumstances, not now neces- sary to be discussed, render it both physically and mechanically less susceptible to the influence of external agency. In a word, a plant is then less organic, or approaches nearer the condition of an inorganised mass, than when its vegetative and vital prin- ciples are in active operation, and exhibits a corresponding inert condition. It is, I am aware, a prevailing opinion that this spring-tender- ness, of which I am speaking, arises wholly from constitutional peculiarity — an hereditary quality, induced by the nature of the seasons in the country or district from whence any given plant may be a native, and which still continues to evince itself under adverse circumstances. But I believe that such peculiarities arise, not so much from a natural tendency in the individual to put forth its buds at a particular season, as from its being in- duced to do so from the influence of local circumstances attending the situation in which it may be placed. A change of country, with a corresponding relative alteration of season, would lui- doubtedly aflfect in a material degree any plant removed from one part of the globe to another, even though the seasons were in both identical in point of temperature, but diflferent in time of occurrence. Yet careful attention to the peculiarity evinced would in a few seasons induce the plant to adapt itself in some degree to its altered conditions, or rather I should say circum- stances may be suited to the plant, to enable it to take advantage of them. Now I cannot believe that the most enthusiastic disciple of the doctrine of the hereditary transmission of qualities would venture to assert that, even admitting such peculiarity to cling to an originally introduced plant, it would show itself so decidedly in its descendants, removed perhaps some half-a-dozen generations from the ancestor. All gardeners know very well, that a plant may be made to change its periods of growth by artificial means. Take the vine as an example. Under ordinary out-door tivat- 144 ON SPRING-TENDERNESS IN PLANTS. ment it is perfectly hardy in England, and does not begin to grow, except ia a few rare instances, till after all danger from spring frosts is over. Sometimes it gets " cut " certainly. So does the oak, and much oftener too, an indigenous tree be it re- membered ; and the ash and the elm, and the most coy of our cultivated trees, the mulberry, often gets " nipped in the bud," though late in putting on its spring attire. But to return to the vine. Take one from the open ground, and by artificial means induce it to " break " for a few consecutive seasons at Christmas, and allow it to rest when others are in full leaf and fruit. The summer sun will scarcely prolong its vegetative season beyond what is required for its healthy economy ; and, if you now remove it to the open air, its instincts will not teach it to hold aloof from the influence of excitable causes at a period when such would be fatal to it in its then unprotected condition. It will certainly for a few seasons exhibit a much greater tendency to vegetate at an unnatural season than one Avhich liad not been induced to do so artificially. But no one will believe that if seeds were ob- tained from a vine while under an unnatural period of growth, and plants obtained from them, that they too would naturally attempt to put forth their leaves at Christmas. I believe that in a great measure the periods of vegetation and its attendant phe- nomena may be changed in relation to the seasons, and tliat such phenomena do not result periodically and under apparent adverse circumstances from any inherent and unchangeable quality in the individual itself, but that it in a great measure depends on the circumstances by which the plant is surrounded, and that in pro- portion as those circumstances are under control or direction, so are the results which must arise from those causes. It may, however, be urged in opposition, that out-of-door culture is a veiy different affair as regards the management and modification of climate, from having to do with glass-houses and all the attendant aids for creating an artificial and spoiling a natural climate. I grant it ; yet the action of natural climate may be much modified, and of course the results in a corresponding ratio, with reference to plants in the open air, and their tendency to subject their young growths to the nipping frosts of spring much obviated. It is not fair to condemn a plant as not being hardy purely because it gets its young growths cut off by spring frosts, and to discontinue its cultivation accordingly. The hardiest of our indigenous trees are often severely cut by their agency, yet we do not consider them the less able to withstand the climate, and merely view such as natural and imavoidable contingencies. And in a small number of trees this influence of frost could be wholly avoided if it were thought necessary. A short time since I was conversing with a gentleman who ON SPEING-TENDERNESS IN PLANTS. 145 had spent much time upon the Himalayan mountains, in tlie district where the scarlet Rhododendron arboreum grew abun- dantly. He assured me that in their native habitats, when occu- pying warm southern slopes, they suffered much by the destruction of their blossom buds from the late frosts, almost as much as the early blooming kinds do in the gardens of this country, while, on the contrary, where growing on northern aspects and experiencing a greater intensity of frost they were uninjured. These are facts, exemplifications of which we can witness every spring, in a more or less degree, in the gardens of this country. Early flowering hardy plants are of no use as a general rule in our gardens. Wet, winds, and frost will not associate with bright and fragile corollas. The two are incongruous and in- compatible. Plants which bloom in the open air before May have little chance of expanding their flowers. But of blooming plants I did not intend to take cognizance in this paper further than as illustrative of the principle which I intended to elucidate, though it will be obvious that they come into the category of spring tender plants. To ornamental evergi'eens, such as Coni- ferae, I intended these remarks especially to apply. An uniform temperature would be almost as injurious, though in a different manner, to vegetable life as an excessively fluctu- ating one. But so long as plants are not unduly excited, and then as unduly retarded or checked, much damage will not accrue. It is the alternate exciting by the influence of spring suns and the antagonistic check by the frosts at night which pro- duces the disastrous results, and renders plants spring-tender. To counteract these injurious effects such hardy plants as are known to be highly excitable should be planted in such a situa- tion as will remove them as much as possible from the influences which induce such excitability, for by removing or combating the cause you of course prevent in an equal ratio the results. Many plants are only spring-tender during the early years of their growth, and when having reached four or five feet of altitude evince no susceptibility to their influence. Abies cephalonica is a remarkable instance of this. "Within a few days I have exa- mined some of the earliest introduced plants, which for several years after being planted scarcely progressed at all, being inva- riably much damaged by spring frosts. The fact of their pro- gressing very slowly is evident enough when the lower branches are examined. They are now as luxuriant and as spring-hardy as could be desired. The comparative hardiness of the same species in various districts is apparently of a very anomalous character, and cannot be explained otherwise than by attributing it to the influence of 146 ^^- SCIILEIDEN'S TIIKORY OF AGHrCULTUEE. local causes ; but, from the facts wliioli may be gleaned from an investigation of the subject, theie cIi- SCHLEIDEN'S TIIEOltY OK AGRICULTURE. cause. Many mosses and liverworts can be bvonglit to fructify under cultivation only when covered with green glass, which imitates the peculiar light of the places in which tliey naturally grow. Electricity, beyond doubt, is a powerful agent in vegetation, but at present we are not in a condition to estimate its influence. The luxuriance of growth after a thund<;r&torm is well known to be such as the mere quantity of rain which descends is not at all sufficient to explain. C. The geological nature of the subsoil was the third point mentioned. With respect to site, a gentle slope towards the south-west is the most preferable, except in very thin, dry soils, and the lower the land lies the more probability is there of accessions of inorganic matter from above. A too rapid inclination causes the water to run off too rapidly, often to the destruction of the soil. Under these circumstances, however, the want of a pervious substratum may be less felt ; and even where it is rocky, the shallowness of mould, other circumstances being favourable, may be compen- sated, and the cultivation of deep-rooting plants be possible. Tlie mechanical composition of the substratum is also of great import. Firm rocks, and difficult of decomposition, present an absolute impediment to any penetration beyond the external soil. Coarse masses of gravel or rubble, which have no power of im- bibing the substances lixiviated from the soil and in turn of restoring them when needful, are equally injurious. The most profitable subsoil is afforded by alluvial or diluvial strata of sand, clay, marl, &c., but of these the worst is sand, unless constantly moist from lying at a sufficient depth. The great advantage of these substrata is, that tillage may be carried to any depth, and next in order come such strata as consist of stone, which is loose and easily decomposed. Nor is its chemical nature of less consequence. On this depends the richness of the soil in inor- ganic constituents, and those subsoils which the more easily part with these constituents are the most favourable, such as volcanic ashes, lava, and basalt ; after which come feldspathic porphyry and granite. Pure sand and lime, free from admixture of clay, are the poorest. Those strata also which crop out and whose fractured ends are exposed are better than those where the sur- face follows exactly their dip. In fact, on the subsoil in great measure depends the just degree of drainage, temperature, and other circumstances, and in general the looser the soil itself is, the firmer and more compact should be the substratum. II. There are, however, other circumstances which are more or less under the power of the cultivator and on which success immediately depends. He can form a soil where none is present, Dl{. SCHLEIDEN'S THEORY OF AGRICULTURE. ]51 unci with few exceptions can modify it in till its peculiarities. Each circumstance must, nevertheless, be carefully distinguished in the inquiiy and its especial influence noted. The matter may be considered under tAvo heads, the physical and chemical pro- perties of the ground. A. a. The quantity and state of aggregation first require no- tice. Other points being equal, the most favourable circum- stance in soil is its depth. Some of the virgin forests of Ame- rica, without any manure and with scarcely any labour, will yield abundant crops of tobacco for centuries. The mean depth of soil, how^ever, in our fields is about 6 inches, but the only limit to improvement in this respect is a substratum of hani stone or un tractable water. Some plants require a much deeper soil than others. The white mountain clover, for instance, and sainfoin succeed best in a shallow soil,lucern and common clover in deep layers. Plants with spreading roots never grow so thick as tliose whose roots run deep, and tliese, when compelled to ex- pand their roots in wet ground, require more lOom, consequently seed may be sown thicker in deep than in shallow soils. The deeper the soil is, the more independent of course it is of the subsoil. In the southern States of America, for instance, as also in many parts of Hungary, it is so deep as to make the nature of the substrata quite indifferent. The composition of the soil, however, apart from chemical considerations, is equally im- portant. Deep sands like those about Berlin, which sometimes are carried oflP together with the whole crop which they sustain, and plastic clays which are turned by the heat of sunnner into stone, are the extremes. Between these there are innumerable gradations, varying in the degree of fineness and looseness, of very different value in proportion as they are suflficiently reten- tive to allow of no waste of chemical matters, and loose enougii to permit the free penetration of the rootlets. b. The capabilities of soil, as regards temperature, is the next point to be considered. According to Schubler, the temperature depends very little on its chemical constituents, but principally on its colour, and on the moisture it contains. The darker it is, the higher in general its temperature ; consequently vegetable mould has in this respect a very decided influence. Humus, however, is an active agent in point of temperature, not only as regards its colour ; its loose structure continually saturated with oxygen favours extremely the process of decomposition of the organic substances in the soil ; or in other words, a con- tinued combustion which must elicit a quantity of heat equivalent to the results of combustion. How important this is will appear from the following consideration : — If we assume the deptli of very good soil, and rich in humus, to be eiu:ht inches, there will INI 2 ]52 I^R- SCHT.KIDEN'S THEORY OF AGRICULTURE. be rather more than two millions of pounds to the acre ; accord- ing to Saussure, 8^ per cent, will be consumed by combustion in a year, that is more than 160,000 lbs. ; a consumption capable of raising the temperature of the water contained in the soil 3° of Reaumur. As regards moisture, the ground is less suscep- tible of warmth the more evaporable water it contains, since the evaporating fluid consumes the iieat which is present in the process of tlie formation of steam. If, in addition, it has a pale light colour, it is almost incapable of receiving heat. The actual temperature of the soil is in an inverse proportion witli its susceptibility of Iieat. Since a body, on an average, radiates heat the more readily it receives it, there may be soils which attract heat slowly, and therefore are cooler in summer, but which give off their heat also slowly, and therefore are warmer in winter. We are only speaking however of heat directly received from the sun. There is sometimes an accession of heat independent of the sun, namely from the irrigation of running water. Springs have generally a lower temperature in summer, and a higher in winter, than the surrounding atmos- phere. In consequence, the formation of seed in water-meadows must be checked in summer, and vegetation kept up in winter, on which principle their great produce is most easily explained. c. One of tlie most important properties of soils is the power with which they imbibe gases. The question here relates prin- cipally to those which are most important to vegetation, as car- bonic acid and ammonia. Unfortunately, though tables exist relative to the absorption of oxygen, there are none which show how the matter stands with those just mentioned. Oxygen is needed only during germination. Where, however, no actual chemical combination exists, it appears that, when one kind of gas is powerfully absorbed, anotiier is also powerfully absorbed by the same substance ; and, there- fore, assuming this to be the case, we may use the existent table for an approximation to the results which may be expected with carbonic acid and ammonia. Now these gases are absorbed by all absorbing substances, and particularly by water, which is of especial consequence to our question, in incomparably greater quantities than oxygen ; and we may therefore assume that the same law liolds good with reference to the soil. With respect to clay, for instance, it is known that, when heated, it begins attain while cooling to receive ammonia from the atmosphere. Many of the constituents of humus have so great an affinity for ammonia that, as for instance crenic and apocrenic acid, they were a long time considered as nitrogenous combinations when we were not in a condition to separate them from ammonia. According to some authorities, humus and humic acid, ulmin DR. SCHLEIDEN'S THEOKV OF AGEICULTURE. 153 and ulmic acid, especially in a moist state, neutralize twenty or thirty times their volume of carbonic acid or ammonia. It appears then from the tables above mentioned that pure quartz sand has the smallest, lime and gypsum a medium, clay and humus the highest power of absorbing carbonic acid and ammonia from the atmosphere, on which alone the proportionate fertility of these soils depends. d. The moisture of the ground is however the medium of these powers. Dew and rain will not by themselves supply the demands of vegetation, and therefore the soil must have the power of absorbing steam from the atmosphere. And tins power is in exact accordance with what has just been mentioned with respect to carbonic acid and ammonia. And to this must be added that property of retaining water when absorbed, as well as of absorption. B. The chemical peculiarities of the soil form the second liead under this division. Soil which is capable of producing plants in luxuriance must contain the necessary chemical constituents. It is not immaterial in what combination these exist in the soil, which must also contain many constituents which are not neces- sary for nutrition, but whose presence and quantity affect the physical qualities of the soil, which are themselves of great moment. a. Insoluble combinations are of course useless to plants, however rich they may be in the requisite materials. On the other hand, analyses which regard merely wliat is held in solution, inasmuch as a greater portion is carried off by drainage, are, in great measure, useless. The most important constituents of the soil are those which are gradually rendered soluble by the decom- posing influence of water containing carbonic acid and ammonia, and partly also by the oxygen of the atmosphere. Silicates, rich in alkalies, answer these conditions. The most favourable com- binations are those in which the requisite inorganic matters are contained in organic substances, w hicli protect them from imme- diate solution, and still, in consequence of their constant decom- position, part with them as the exigencies of the plants require. Almost all important inorganic matters are destructive or injurious to plants when concentrated, and therefore they must be carried by the water away from the influence of evaporation, which might concentrate them too much, or at least they should be in such chemical relation to water, that it can contain only a certain quantity, and therefore on evaporation parts with the superfluous quantity in an insoluble state. Plants are not capable of selecting their food. The chemical constituents must, therefore, exist in the proper proportion. In uncultivated soils, where the proportions necessary to a particular plant do not 154 I^K. SCIILEIDEN'S THEOllY OF AGBICULTURE. exist, or where they are exceeded, the species will not grow ; and in the case of cultivated plants, certain conditions are neces- sary for the perfect success of each species or variety. It is possible that different conditions may be requisite or desirable at different stages of growth, a point which requires attentive study, as also in what order and in what quantities the con- stituents of organic materials become free under the influence of weather or decay, and thirdly, in what proportion, at different periods of the year, and in different stages of vegetation, sucli dissolution and decay take place. If vegetable mould cannot be regarded as the actual nutriment of plants, with reference to their organic constituents, yet some of its constituents are probably not without importance for the supply of their inorganic elements. Besides that many salts are changed when in contact with decaying humus into easily soluble carbonates or more salutary to vegetation, there ai'e two acids contained in humus, the crenic and apocrenic, which, through their remarkable properties, are in a condition to supply a great quantity of inorganic matter to plants, without, at the same time, overwhelming them with a great mass of organic substance. Both acids are pluribasic ; the apocrenic, for instance, is 5 basic, that is, it contains I equivalent of acid, and 5 of the base ; therefore double and triple salts are easily formed ; and if but one equivalent of ammonia be present, the salts are easily soluble. It must be remembered, that this condition must be reversed, if the organic substances of the ground were really destined for the organic nourishment of plants. h. The physical nature of the soil must be in a proper relation to its chemical constituents. Sand, lime, clay, and humus are the elements of the question. These, if properly proportioned, will satisfy the necessary conditions of vegetation. About 40 or 50 per cent, of clay seems the best proportion. A greater quantity makes the ground too stiff, and also, from its retention of water, too cold. With less than 10 per cent, it will be too light or poor. Humus is here, however, of the greatest moment. Its very loose consistence acts with extraordinary rapidity on the texture of clay, while its attraction and reten- tion of water serve in the most wonderful degree to bind sand together, as appears from the fertility of the red soil of Cuba, which is naturally free from humus, and the Brazilian and Nortli American forests, which consist of nothing else ; so that, under favourable circumstances, clay may replace humus, and iuunus clay. The following table shows, in the most striking way, tiiat the fertility of soil is proportionally quite independent of the humus which it contains: — DK.

Tliis leads to the subject of fallowing, then to varioiis modes of working- the land, to manures, to drainage, and finally to rotation of cropping-. Some of these have already occupied so much room that they must be passed over in a few words. A. Under the first head we shall content ourselves with pointing- out the necessity of embracing- every opportunity of improving- the objects of cultivation. Wherever any peculiar qualities exist in a particular plant, especially adapted to any particular soil, that plant should be carefully preserved, and every circumstance about it noted. Those who cultivate on a large scale, and extensive proprietors, may thus in process of time acquire valuable varieties or information as to the points which have produced any especial good qualities, to the great benefit of society. But in cultivation on a small scale, mucli dei)ends on a cautious selection of seed. It should be perfectly ripe, clean, and free from admixture of weeds, and care should be taken that it was grown upon a suitable soil. That which comes from a barren field is much more likely to be true to its variety than what comes from highly manured land. In general, the time of sowing depends upon circumstances which place it out of the power of the cultivator to choose his weather; rye and barley, however, recpiire a drier time than oats. B. As regartls tlie knowledge of the soil, thisnuist be obtained by actual examination, though not by a perfect cliemical analysis. No certain judgment can be formed by its natural produce, but 156 DR. SCHLEIDEN'S THEORY OF AGRICULTUKE. an inspection of its physical condition and general chemical con- stituents, such as may be made by simple mechanical processes and a slight degree of chemical manipulation, which will give not only a notion of its present worth, but of its future capa- bilities, is almost indispensable. C. The object of ploughing, and other allied processes, is the deepening of the soil, the alteration of its texture, either by the mere mechanical action or admixture of organic and inor- ganic manure, and the destruction of noxious weeds, to which may be added the necessity of placing the seed in a fit position for vegetation, and protecting it from birds and other noxious animals. It nmst be borne in mind that, Avhile the opening of the soil subjects it to the influence of the atmosphere more com- pletely and to a greater depth than would be otherwise possible, the humus is rendered liable to rapid decomposition, such as may more than overbalance any good which might arise from the exposure of the surface ; and this destruction takes place at the very time when it is not available for the demands of vege- tation, added to which the most valuable portions are often carried off by an overflow of water. Ploughing, then, must be considered rather as a necessary evil, and one to be employed only so far as necessity requires. Because frequent ploughing is useful in some cases, it is not to be assumed hastily that the rule is generally applicable. D. The doctrine of fallows will require a rather more copious abstract. The word was originally applied simply to land wliich was left uncropped, and may be considered exactly opposite to tlie employment of manure. Afterwards the system was some- what complicated by the introduction during the last century of leguminous plants, such as clover, especially from Italy, where the system had long been practised, and fallows, in tlie old sense of the word, have in great measure become obsolete, though it was long retained for matters with which it was originally entirely unconnected. We may define it as follows : Fallow is that condition of the land in which, during one or more years, notiiing is taken away in the shape of harvest, or added in that of manure. In this strict sense the grazing of cattle on the fallow-field would be excluded, but, inasmuch as through grazing there is so little in- frino-ement on the proper purport of fallow, it is included under our notion of the word. Fallows may be divided into green and naked fallows : in the first the land is suffered to clothe itself with a thick coat of weeds ; in the second it is kept bare by one or more ploughings, so as to be constantly exposed to the influence of the atmosphere. 1. The thick covering of soil with vegetation hinders in many ways the action of the atmosphere upon it. The shading of the DK. SCHLEIDEN's THEORY OF AGRICULTUEE. 157 leaves keeps off the direct sunbeams, and consequently impedes evaporation. The moisture is therefore retained for the exi- gencies of the plants, which are consequently more luxuriant, as also from the increased absorption of carbonic acid ; while the consumption of humus is either prevented or prolonged from the stagnation of the air immediately in contact with it, since an atmosphere of carbonic acid, the produce of decomposition, sur- rounds the constituents of the humus, impeding the accession of fresh oxygen, and consequently of further decay. Those parts meanwhile which are slowly dissolved are stored up in the plants which cover the ground, which constantly receives an addition from the falling leaves, and the accession of vegetable matter is eventually greatly increased by the ploughing in of the green covering. The benefit of such fallows to poor and light ground is at once evident. 2. In the naked fallow, weeds are not allowed to come to their full growth. The increase of humus is therefore slight from this source, while it is sensibly diminished by the constant ploughing, the dissolution of its mineral constituents proceeding with equal rapidity. These unfortunately are subject to be washed away by overwhelming rains. The naked fallow is only useful then where the requisite looseness of soil camiot be at- tained in any other May. The notion of rest so prevalent amongst cultivators is clearly wrong, except it be rest from the destructi^■e influence of the plough. E. The subject of manures has already been touched upon so much that we must content ourselves with some general remarks, without entering upon any special substances, which are treated at considerable length by Dr. Schleiden. There is the less need to follow all his observations, as much is accessible to English readers in the work of Boussingault. The word manure, taken in its widest sense, comprehends everything that is put to the land with a view to the improve- ment of the crop, whether organic or inorganic. Ko agricultural operation can satisfy one condition alone of vegetable life. It is by manure almost exclusively that man is able to alter the character of land, and the supply of nutriment from it is so far from being the only object it answers, that in many cases it might be doubted even whether this were the principal end, and therefore the indi- vidual properties must be separated carefully from one another. If we consider the waste which takes place in the consumption of what is carried out of the field, that in such crops as flax scarcely anything is returned, that a large portion of the organic matter is destroyed by the process of combustion, it will be evident that, without having recourse to fallows or green crop- ping, it would be impossible to cultivate land with mere farm- 158 I5I^- SCHLlilDliN'S THEOKY OF AGKICULTURE. yard manure, and that the organic matters can be merely acces- sories, and not the most important principles. It must be remembered, too, tiiat the animal world depends ultimately for its existence on the vegetable kingdom, and there- fore what animals reqiure for nourishment must be necessary and not accidental constituents of plants. Manmialia want, for in- stance, lime and phosphates for their bones, iron for the colouring- matter of their blood, nitre for their bile, muriates for their gastric juice, and probably they could not live without potash and sulphur, which we find in all their fluids. These then of necessity must enter into their composition, and in grasses flint is indispensable, though we do not find that it exercises any important function in animals. This latter principle is universally diffused, while phosphates are comparatively rare, and therefore demand the first consideration. They exist in animal manure, especially in human ordure, combined with lime, magnesia, and ammonia ill a soluble or insoluble form, and are supplied largely by bones, which in England are imported extensively from the Continent. Tiiere are many tables which seem to indicate that manures are profitable in proportion as they are rich in nitrogen ; but the experiments from which they were derived were made under pre- judiced view^s, and they show that their beneficial character is at least as clearly indicated by their alkalies and phosphates, as appears by the tables of HermbstJidt and Kuhlraann. Alkalies are very generally diffiised in nature, though there are lands almost destitute of them which require a proper admixture. These besides generally form highly soluble combinations which are easily carried away by water, and the plants which grow in the neighbourhood of dung-hills and firm-yards are especially those whose ashes abovuid in them. A great waste, therefore, must occur, which ought to be carefully replaced. Chili salt- petre, a natural nitrate of soda, has been mvich recommended. That tlie alkali, and not the nitrogen, is the active principle here appears from the fact that the increase in hay and straw from manure with nitrate of soda contains twice as much nitrogen as the salt used for manure. Lime is a very general principle, and as the carbonate and sulphate are not very soluble a good deal remains in dung ; still there is waste, and some kinds of land are naturally deficient in this principle. Marl and gypsum are the great sources from which it can be artificially supplied ; the latter also affords sulphur. Iron, magnesia, sulphuric acid, and nuiriatic acid may be classed together, because they are of less importance than the others, and need no particular observations. Magnesia, though pi-esent in small quantities, seems to have an important office (perhaps from its relation to phosphoric acid) ; at least, it is surprising that in the ashes of most plants it bears a greater projiortion to lime than it does in the soil. DR. SCULEIDEN'S THEORY OF AGRICULTURE. 159 Flint is so universal that, however necessary, it scarcely ever requires to be supplied artificially, and if so the point would be to apply it in a soluble form. It must be remembered that the greater part of the silex comes back to the land with the manure, while a proportionately large quantity of the more valuable con- stituents is carried off with the grain, a circumstance of great consequence in estimates of cropping and manure, as the relative proportions on which so much depends are totally deranged. It does not follow, though under certain methods of farming more inorganic matter comes back continually tliau has been taken away, that inorganic matters are not the important consti- tuents in the nutriment of plants, because, if the alkalies in the harvest be as 2*3, and that in the manure as 2-17, or on the addition of turf ashes, as practised by Boussingault, as 2 "30, the conditions are altogether different, a fact which seems to be too often overlooked. A very few words on organic manures must suffice, as so much has already been said on the subject. Nitrogen is received from dung in the form of ammonia. It is a common notion that the proportion of ammonia contained in manure is of great value as regards the nourishment of plants, which is sometimes regarded as the only source from whence tlie nitrogen contained in plants is derived. The great produce of water-meadows, which receive no dung, is sufficient to show that this prejudice is not well founded. Peruvian guano containing 29 * 88 lbs. of nitrogen has almost the same effect as bone-jelly containing 82' 55, and one-third more than sulphate of ammonia containing 50 'To. The substances which have most effect as manures are those which are rich in phosphates, and in a series of experiments the greatest effect was protluced by Flemish dung, consisting of urine and pure human excrement, which is rich in alkalies ; and that these ought to be taken into consideration is proved by tiie favourable effects of Cliili saltpetre (nitrate of soda). It is re- markable too that bone-ashes, rich in phosjihate of lime, produce no effect by themselves, but, when combined with ammoniacal water from gas-works, their effect is surprising, a result wiiich probably depends on the dissolving power of the ammonia on other substances, and especially on phosphates. On the whole then it appears that, except in cases of an inex- haustible depth of soil, cultivation cannot succeed, or at least the fertility of the land be fully sustained, from the resources of the soil itself; either a portion must be in meadow, or additional manure must in some shape or other be introduced. B. Manures act also on the physical constitution of the ground. The power of absorbing steam and gas from the atmospliere depends almost exclusively on the quantity of clay or humus. The great pohit undoubtedly is to keep up the supply of the 160 UR sen LEIDEN'S THEORY OF AGRICULTURE. latter, to protluce which is the great office of the organic matter ill manure. The manure, however, made upon a farm will not suffice for this, without there is a proper proportion of meadow or of artificial grasses. Other physical conditions, as temperature, looseness of soil, are also promoted by this substance, which liow- ever on strong clays may, to a certain extent, be replaced with sand, and on loose sands with clay, where it is profitable to do so. C. The regulation of water or draining is absolutely indispen- sable for good cultivation, while, on the other hand, the freest irrigation is of immense advantage. The difference arises from the state in which the water is which comes in contact with the roots of the plants. The poorest vegetation exists in moors and peatbogs, which are constantly saturated, wldle the richest is found in alpuie meadows constantly irrigated. The difference is, that in the one case the water is stagnant, and in the other constantly changed. Plants require but little sulphur, and consequently sulphuretted hydrogen, supposing that they receive their sulphur in this form. Sulphates in contact with decaying organic substances soon unite with them, and tluis sulphuretted hydrogen is generated in such quantities as to be destructive to many plants. D. A few remarks on rotation of cropping must close our abstract. Experience has shown that fallows may be in a great measure dispensed with by a system of rotation, including clover. The object of science is to show in what way this is explainetl by the nature of plants, and inasmuch as improvement is impossible, or at least accidental, without knowledge, such inquiries have their practical side. It is on the cultivation of clover that the main advantage of rotation depends, the object of it being to increase the quantity of humus ; and it is to be observed that in the pub- lished tables a very important part of the accession derived by the field is neglected, namely, that from the leaves which are constantly withering and falling off, which amount perhaps to twice or thrice as much as what is carried away. Wheat, like other cereals and grasses, will succeed without humus, provided the requisite moisture be kept up, but where this is not possible there must be either a verj' favourable clay, or the groiuid must be very rich in hiunus ; but, in consequence of their thin leaves and slender hollow stem, they cannot take up a great quantity of moisture at once in anticipation of a dry time, and therefore they require an uninterrupted supply of moisture, which must be afforded by absorption from the atmosphere by means either of the clay or vegetable mould. There are two points to be distinguislied Mith respect to rota- tion. First, it may be regarded as a whole, as a method of culti- \ ation by which cloxer takes the place of fallow, and by u hich a greater produce of cereals is possible ; and this leads to the DR. SCHLEIDEN'S THEORY OF AGRICULTURE. j (Jl cultivation of other plants, so that a greater number enters into the question. Hence a second subject of inquiry, in what order ought these to succeed each other ? The first question needs no further observation. The second is unfortunately one of great difficulty, for the solution of which but few data exist at present. Experience informs us that two crops of a similar nature should not succeed each other, and science at present can do no more. The matter of greatest con- sequence will always be with what plant to begin the course. Inorganic matters ought not only to be present in the soil, but in the right proportion. The worst method then should seem to be to begin with the potato, the contrary practice for so many years being probably one of the main causes of the present depraved state of the plant. The choice must be directed by a comparison of the inorganic constituents of the dung with those of the plant proposed, so that that plant will be taken first which on analJ^sis bears the nearest proportion to that exhibited by the manure. If then the inorganic contents of the harvest be sub- tracted from those of the manure, the second plant will be chosen according to its relative proportions, and so on through the whole of the course. Now, if we compare the contents of ordi- narj' manures with those of agricultural plants, we shall find that potatoes and wheat are those which have the most distant relation. They are those which are subject to most diseases. If the com- parison be continued, and attention be paid to the proportion of the most influential constituents, namely, the phosphate of lime and magnesia to the sulphuretted and muriated ali.>.>, c sn ^•2 » .T 2 O » .— CO o — . a c J £5 1 REPORT OF THE COUNCIL, MAY 1, 1852. 175 Upon analysing the items in the Balance-sheet, and compar- ing' them with tlie corresponding items in the accounts of last year, it will be found that the receipts have been greater by the sum of 558/. 0*. lOd., as shown by the folhjwing statement : — Income. 1850-51 1851-52 Compositions for Life from Fellows . £. s. d. 84 0 0 2825 6 8 £. s. d. 2533 12 0 Admission Fees from Fellows . . . .

ORIGINAL COMMUNICATIONS. XII. — Observations on the Diseases of Plants as illustrated hy the Potato Murrain. By Dr. Schleiden. [The present memoir, which is here very slightly abridged, to avoid needless repetition and render it more suitable to this Journal, appeared in the form of an appendix to the treatise of which an account has been given in the two previous num- bers. Though the primary subject is in itself scarcely calcu- lated to excite attention after so much has been written on it and is still daily overloading the Continental press, it is of great importance as regards its general bearing on the diseases of plants, and for this reason is submitted to the Society.] The general features as well as the especial marks of dis- tinction which are exhibited by the more important diseases to which potatoes are subject, are so extremely various, that it is necessarj' to examine a large quantity of specimens before we can draw up the essential characters of any particular disease, so as to be entirely free from individual and local circumstances. Since the first appearance of the potato-murrain I have paid con- stant attention to the subject, collected all possible information, and carefully examined a great quantity of tubers from all parts of Germany, without however finding any reason to alter the views which I entertained in the year 1845. My prediction that the malady was independent of temporary causes, and that it would never disappear, has, at least at present, been sadly verified. 1. The following general remarks, which are founded on in- formation derived from various quarters, are of great importance to the due estimation of the nature of the disease. And first I must protest against the erroneous notion that the malady is of recent origin. The cultivation of potatoes diffused itself very slowly over Europe, and especially in Germany. From its very first commencement complaints were made of degeneration and disease, which became still louder and more urgent as it ex- tended ; and indeed every one well acquainted with the history of the potato is aware that from the middle of tiie last century, a few years only were free from disease, every succeeding year in general exhibiting some more aggravated and widely extending form. DISEASES OF PLANTS ILLUSTKATED BY THE POTATO MURKAIX. 179 General attention was first attracted to the subject in particular countries in 1840, which extended in 184o to the whole of P^urope. Since the former date disease has been more or less prevalent, thouo-h the climatic conditions have been as various as possible. No especial variety has been entirelj^ exempt, or indeed has uni- versally exhibited the disease in a milder form. No single kind of soil has been entirely free, or even peculiarly privileged. In the nei"'hbourhood of Jena, for instance, cases have occurred wliere potatoes have succeeded extremely well in ill-drained moors, Avhile the crops in tlie neighbouring sands have been wortliless. No particular situation seemed to make any difference, with the single exception, and tliat of some importance, of the whole ex- tent of coast on the Nortii Sea. as far as the immediate influence of the sea-fog extended. Whether the crop was raised from seed, from entire tubers, from sets or eyes, the result was just the same ; or perhaps those crops which were immediately derived from seed exhibited the worst form of the disease. Moreover, the crops suffered indifferently, whatever peculiar place in the usual rotation they might occupy, except indeed that the murrain appeared the latest, and was first ameliorated, where potatoes, as in Thuringia, are never planted, on a large scale at least, in fresh manure. The first symptoms of disease appeared in the tubers as soon as in the haulm, or even sooner. It is at least indubitable that highly diseased tubers proceeded from perfectly sound haulm, in which therefore the cause of the disease could not reside, nor could it be propagated from the green parts to the tubers. On the same plant sound and highly diseased potatoes frequently occur, and in the same heap during winter sound tubers are found amongst those which are quite putrid, from whence I conclude that the disease is not connuunicated by con- tagion. 2. The first symptom of the disease consists of brownish dis- coloured specks which extend from the superficial cells inwards. The nitrogenous lining of the cells, which in sound tubers is colourless and uniform, assumes the appearance of a pale yellow membrane. As the disease increases, this membrane is finely granulated, giving off reticulated threads in which a distinct circulation is often visible. The nucleus at the same time be- comes sharply defined ; the nitrogenous coat assumes a darker tint, the starch-grains are absorbed exactly as in a sprouting potato ; in short the phenomena are the same as occur generally in germination, a circumstance which agrees remarkably with the fact that diseased potatoes, when they do not pass too rapidly into a state of putrescence, have a surprising tendency to germi- nate, in consequence of which, after three or four weeks, they are often covered with young tubers. VOL. vii. o 130 OBSERVATIONS ON THE DISEASES OF PLANTS In process of time the intercellular passages, which normally are filled with air, are injected with a yellow fluid. Tliis takes place even in the vessels, when once tliey are attacked by the disease. In tliis fluid sharply defined granules soon appear, and at length mycelium arises both in the intercellular passages and cells. The individual cells separate from each other, their walls become attenuated, and at length disappear. In general the starch-grains remain involved in fungal threads, and the wliole dries up into a hard white mass, or if the decay is more rapid, the amylum is destroyed, so that frequently nothing remains of the whole potato except a thin sac filled with a fetid fluid. Parasites, whether insects or fungi, are never original, but de- veloped on the diseased tissues. 3. I shall now offer some remarks on the chemical condition of the infected tubers. The juice of sound potatoes is slightly acid, whereas the dis- eased spots exhibit at times a weak alkaline reaction. As the disease increases, sometimes a decidedly acid, sometimes an equally distinct alkaline reaction takes place, M-ithout any assign- able reason ; in the latter case the circumstance does not depend alone on the presence of ammonia. The liighly fetid tubers react clearly on ammonia, as is of course the case in the decomposition of nitrogenous substances. Tlie walls of the diseased cells are at first blue when treated with iodine and sulpliuric acid, then, as the disease is progressing, successively greenish blue, green, and greenish yellow, and finally dark golden yellow or brownish yellow. The nitrogenous matters become darker when treated with iodine in proportion as the disease advances, and, according to Liebig, consist no longer, or at least not principally, of albu- men, but of casein. The starch grains, in all potatoes which are strongly affected, even in the cells which still remain sound, exhibit a peculiarity which distinguishes them from the starch of sound tubers. As soon as it is dry, a quantity of broad cracks are formed within them. This is never the case with sound potatoes, and proves that these bodies in diseased tubers are far more saturated with water than in those which are sound. When boiled there is also a great diflPerence. Diseased tubers boiled for four hours remain as hard as at first ; if they are then quartered, and the cortical layer removed, they remain unchanged though repeatedly boiled, while sound potatoes from the same field, after three hours, burst and separate into individual cells. The starch in the cells of diseased potatoes when boiled swells out into little gelatinous sacs, but these remain single and un- connected in the cells, and do not long fill them out. Observations on diseased potatoes as compared with sound, by Payen, Schacht and Janssen, Petzholdt, &c., give the following: AS ILLUSTRATED BY THE POTATO MURRAIN. Igl actual variations. The amount in water and ashes in diseased potatoes is absolutely more marked, in starch less so than in those which are sound. The albumen is relatively more marked in proportion as well to the starch only, as also to the collective non-nitrogenous constituents. Most chemical analyses of diseased potatoes are useless inas- much as they are made without any knowledge what is to be gained by analysis, and what questions are to be answered by it. One of the best and most worthy of confidence is that of Janssen and Schacht, but, like all similar analyses of plants, is deficient as regards the nitrogenous constituents. According to this the proportion of albumen to starch in sound potatoes is as 1 : 31,8 ; in diseased as 1 : 28,7 ; to starch, cellulose, gum and sugar col- lectivelj^ — in the sound as 1 : 25,8, in diseased as 1 : 36,6. It is remarkable that diseased potatoes, according to this ana- lysis, which in this respect is very careful, contain more cellu- lose than those which are sound, and if the cellulose is set down at unity, the following jiroportions are obtained, which perhaps approximately correspond with the proportions in the single cells.

This is not the place to treat on every individual malady to which plants are subject, but merely to bring forward the general points of view whicli arise from a physiologico-chemical exami- nation of the little which we know of the diseases of plants. It is not my intention to advert to the destruction of plants or por- tions of plants arising palpably from external agents, but merely to examine the alterations which depend upon an inward abnormal condition. Two things must here be distinguished, the diseases of plants in free nature and those under cultivation, including those wild species on which it exercises an indubitable influence, as corn- weeds. As regards the first, the question may be asked, whether diseases at all affect them, or are capable of doing so, when they are left entirely to nature, and are removed from every influence of man ? The answer to this question would lead us too far. It is, however, indubitable that diseases do arise in apparently wild plants, as for instance tlie Tyrolese fir-woods were very generally visited by Rust in 1845. The causes of such diseases, however, may perhaps be completely external and merely tran- sitory, and rest most probably on tlie peculiar atmospheric con- ditions of particular years, and therefore vanish of themselves in the succeeding season. But in cultivated plants it is entirely different. Almost all of them are no longer in their natural condition, but, regarded in a scientific point of view, are in themselves deviations from their normal condition. The natural equilibrium in their formation is abolished by the unnatural and excessive development of especial circumstances of form or of particular elements, and they present, to the external injurious influences which in part subsist in the very modes of cultivation, a greater number of weak points. To this is added that a great part of the objects of cul- ture are not in their natural climate, but in a zone whicli is strange and ungenial, and that consequently they are affected by a number of inevitable causes of disease.* It scarcely requires * This mode of viewiug the case leads to the comfortless conclusion, that we shall perhaps never be in a condition to extirpate completely the diseases of our cultivated plants, and that as with us people reckon on the tenth grain, but not upon the hundredth, as is the case in Chili, or as in some places in every great calculation a certain per centage is deducted for the probable destruction of hailstones, so it would be better, instead of writing thick volumes and even little libraries containing treatises on the occurrence and treatment of diseases, to collect correct statical data, with a view to calculate the mean loss due to disease, so as to make it harmless by reason of foresight. In a political point of view beyond doubt the firm establishment of such statical conditions is of the greatest importance, for in AS ILLUSTRATED BY THE POTATO MUKEALV. 183 an express intimation that the condition of a plant as an object of cultivation and its disposition to disease are perfectly iden- tical. Both are alteratious of cliemical action in the plant, pro- duced through the conditions under which it grows. All our cultivated plants, with very few exceptions, may be regarded as diseased ; that is, as deviations from the normal process of for- mation of the species, and it is only the egotism of man which thiniis otJierwise of them, inasmuch as he finds his profit in these diseases as in tlie artificial enlargement of the liver in the Stras- burg goose. The greater part, indeed, if not all the peculiar internal diseases to which plants as well as men are subject, arise from an improper, deficient, or more frequently too abundant, nourishment. In order, however, not to deviate too widely from the common mode of speech, I shall distinguish that condition of cultivated plants in wliich they deviate from the normal form which they exhibit when wild, in consequence of too abundant nourisliment as a general inward tendency to disease. This tendency, however, becomes specific when they belong naturally to a very light or sandy soil, as oats or potatoes, and are now cultivated on heavy ground, or if, in consequence of tlie plan of cultivation which was once imiversal, they are grown in the first year in wliich the land is manured, as wheat, rye, potatoes ; or finally, if the climate in which they are cultivated deviates greatly from their natural place of growth, as is the cast in wheat, maize, and potatoes. Under these circumstances very slight prejudicial influences are requisite, as for instance wet, cold, or extreme heat at an improper time, to cause the appear- ance of disease. The only point which man has in his power is the avoidance of unsuitable soil and site in the cultivation of a plant, which will, however, be exercised by every intelligent agriculturist. Climate is beyond our power, and we cannot increase the general disposition to disease without at the same time hazarding the total loss of any particular species. The outer appearances of the diseases of vegetables are well known, and their specification belongs to the pathology of plants. Tiie inward phenomena, as far as they liave at present been examined, possess something general, which deserves a place here, since it points decidedly to the fact that the general tendency to disease is due to the influ- ence of artificial culture. As the physiology of plants turns on the investigation of the life of a single cell, if it is to be worked out with any degree of every country the most fearful difficulties arise, -when a harvest fails on which dependence was placed. The loss is however entirely free from evil conse(iueuces where it has been calculated and provided for beforehand. 184 OBSERVATIONS ON THE DISEASES OF PLANTS success, SO also in pathological researches we must direct our attention exclusively to the alterations which the individual cells exhibit. In every living cell the substances proper to it are arranged on one simj)Ie plan. The wall of tlie cell is formed of firm, perfectly insoluble cellulose, which, after it has been pene- trated witli this or tiiat matter, and has in consequence lost its purity, is in a condition to exhibit different appearances on the application of re-agents, but abstractedly always the same, and that a non-nitrogenous substance remains, in which, together with carbon, hydrogen and oxygen are present in the proportions in which they constitute water. This cell-wall is lined within by a coat of greater or less thickness, either yellowish or free from colour, consisting of a semi-tluid, somewliat coagulated, gela- tinoso-granular substance, wliich is formed of a proteinous matter rich in nitrogen, and called by II. v. Mold* the primordial sac. Finally, the inner cavity of the cell contains a highly mixed fluid, the medium of whose fluidity is water, in which a few nitro- genous, i^roteinous compounds are present, together with many which are non-nitrogenous, as gum, sugar, pectin, &c., soluble salts, and in a fixed form starch, inulin, and crystals. The relation of the greatest consequence as regards the life of the cells seems to be that of the nitrogenous lining to the other substances, especially the non-nitrogenous, and the vigorous health of the cells to depend entirely on the normal condition of this stratum. When the cell is old and begins to perish (as for instance in the wood-cells), tiiis coat gradually disappears, or is so closely united with the cell-:wall tliat it becomes inseparable, while at the same time it penetrates it in a soluble state, and thus by degrees the original reaction on the cellulose is perfectly masked by the constantly increasing re-action on the proteinous combinations. If we now examine the first deviations from normal phenomena which are exhibited in the occurrence of internal diseases, as for instance in smut (^Uredo segetmit), in decay, as in the stems of Cacti, juicy fruits, &c., or in the potato murrain, we find in every case that the nitrogenous lining of tlie cells first becomes discoloured, assumes a darker tint, a firmer consistence, a more evident granulation, and that it begins at the same time to per- colate and saturate the cell-wall, so that it ceases to exhibit its pure reaction on the cellulose. These phenomena are so general * It is matter of regret that the best organic chemists are so little agreed as to the normal constitution of cells. Schleiden's view is so much more simple than that which regards the proteinous lining as the original cell, that it bears the stamp of truth about it. Mulder's admirable work is, in our opinion, impaired very materially by his trusting so much to the fancies of Hartiff.— Tr. AS ILLUSTKATED BY THE POTATO MUEKAIN. 185 that we may well suppose that all inward diseases of plants actually derive their origin from an abnormal condition of this coat, and inasmuch as the peculiar power of the chemical pro- cess in the cells is apparently concentrated there, its depravation first calls into existence the symptoms of disease which are per- ceptible at a later period in the other portions of the cells. I subscribe, indeed, to the doctrine first put forth by Saussure and Davy, and at a later period extended by Boussingaidt and Liebig, which lays so great stress on the inorganic substances in plants. I believe, as Liebig first expressed it, that the whole multiplicity in the vegetable kingdom, as far as it rests and de- pends on a chemical process, arises in the first instance exclu- sively from the action of the difierent qualitative and quantitative combinations of the inorganic substances which the plant re- ceives from the earth, and that consequently its meagre or luxuriant growth, its healthy or diseased condition, must be de- rived from these substances. It appears to me, for instance, to be clearly established by the investigations of Boussingault and Liebig, that the formation of the organic substances of the Dextrin and Protein Category is entirely dependent on the pre- sence of certain inorganic matters, without which the greatest superfluity of organic elements in the available combinations is utterly useless to the plant. Although it is indubitable that the formation of Proteinous matters depends on the presence of phosphorated salts, that of matters of the Dextrin group, on the contrary, of non-phosphorated alkaline salts, tlie following inves- tigation will render the subject even more probable. The proportional rarity of phosphates in most geological for- mations, and also in the soils which are wholly or principally formed from them, is Avell known ; on the contrary, they are ac- cumulated in soils principally formed of decomposed vegetable matter after being slowly collected by the plants. Animal ex- crements are very rich in these salts, and therefore manured fields, and especially gardens, contain a greater proportion than is normally present in plants, or can be consumed by them. But the influence which inorganic substances in the soil exercise on vegetation depends upon their being generally present. For since plants have not the power of choosing their own nutriment, and since the proportions in which soluble substances present them- selves for absorption can be altered by endosmose within very narrow limits, it is equally important that the substances which are requisite for plants should be contained in the soil in some- thing like the projx^r proportions, since the plants are otherwise compelle vest,inckiding straw j 1-000 0-305 0-124 0-140 0-021 0-550 Subtracted from the A proportions ill stable 1 1-000 1-500 0-629 0-044 0-354 0-301 dung given above, j multiplied by 3 . i Ashes in rye harvest,! including straw .

Most agriculturists agree that rye is most fitted for newly ma- nured land, which is clearly attributable to its greater amount of phosphoric acid. The best rotation then seems to be to begin with winter lye, and to let potatoes follow. I do not, however, give this as a decided fact ; all I would assert is, that the place usually given to potatoes is the worst and most destructive. The choice, however, of another system, if it is to lead to the desired result, must not merely be tried by individuals ; but the earlier methods of cultivation must be abolished, at least as ge- nerally as they have been hitherto firmly established. But unhappily in the very nature of things, any legislative measures can have no effect, even supposing tlie views I have developed to be true. The only measure which a government can take, is to provide by every means at its disposal for the instruction and enlightenment of cultivators, so that on the one side they may possess such well-grounded knowledge of natural science as may enable them to comprehend facts in their just connexion or as actual experience, instead of opposing raw empiricism or the mere observation of facts with the self-sufficiency of ignorance to scientific discussion, and on the other side landowners may STYLE AND EXPEESSIOX IN TREES AND SHRUBS. 193 bring themselves to such a national economical illumination, that their own interest may go hand in hand with the well-being of the whole state, and the first cannot long continue without the last ; whereas at present a narrow-mindedness is frequently exhi- bited, which with confined views works against its own interest, while it holds the nearest profit as the surest, forgetting that a speculation for ten days in the case of mortal men is not more sure than one for ten years. XIII. — On Style and Expression in certain Trees and Shrubs ; their Adaptabilities, Sic By Robert Errington, C.M.H.S., Gardener to Sir Philip de Malpas Grey Egerton, Bart., M.P., F.H.S., Oulton Park, Tarporley, Cheshire. (Communicated April IG, 1852.) Landscape gardening in its strict sense has scarcely kept pace with what has been termed the Gardenesque of late years ; and why ? Simply I suppose from the fact, that where there is one person Avho can appreciate the beauties of lines and forms inde- pendent of colour, there are a score who cannot ; but who never- theless are, it may be, adepts at what is termed " clumping " flowers and all the paraphernalia of the flower garden. Whilst, however, England sustains her position in the van of civilisation, so long must true landscape gardening be fostered ; and it must be confessed, tliat we owe its preservation and encou- ragement mainly to our aristocracy, who are ever in a better position to appreciate its value than any other class of society. My purpose is to draw attention to the beauties of form in certain trees and shrubs, old-fashioned kinds or not, and to point to their eligibilities, whether in the park, the ordinary pleasure- grounds, or the flower-garden. As country' seats differ — and indeed should do so — as to their general tone or expression, sometimes through position and adventitious circumstances, and sometimes as a matter of design, it follows that a judicious adap- tation of trees and shrubs becomes necessary, whether as accom- paniments or as constituting a portion of the chief features of the grounds. In most of the pleasure-grounds connected with the seats of our nobility and gentrj^, certain by-scenes, retreats, nooks, or decorative adjuncts occur, which either possess a kind of indi- viduality, or require it to be created by the skill of the artist. Hence the necessity for a nice perception of the character and ultimate expression of trees and shrubs. The grave and the gay would be terms far too sweeping in their signification to embrace 194 ON STYLE AND EXPRESSION all the objects required in extensive gardens. From the mau- soleum to tiie parterre may exist several intermediate characters, each requiring a separate impress, yet merging into each other. For instance, there may be the rosary, the American ground, the decorated promenade, the terrace, I'ock-work, &c. ; and as matters farther from home, wallcs and acljuncts connected with the mar- gins of the park, the lake, the woodlands, the grove. It need scarcely be urged that each of these requires peculiarity of style in the trees and shrubs which are used as accompaniments. There exists, moreover, in addition, a demand for trees and shrubs adapted to the various styles of architecture ; and to the vestibule, the corridor, balustrades, arcades, the conservatory, &c. Thus far I have pointed to a few of the chief objects, in order to show the demand for a variety and choice of materials, and to mark the existence of such, and to claim in some degree for the landscape gardener an immunity from the ordinary bondage imposed by the great goddess Fashion : the genuine landscape gardener caring more for lines and forms than gaudy colours. Mere novelty and colour, then, being set aside for a moment, I would beg to advert to what we may term style and expression in trees and shrubs, and with much deference submit the following, which is capable of amplification : — Fonns : — Kound or flat-headed, generally massive. Pointed or spiry. Columnar. Fastigiate. Horizontal. Weeping. To these common terms, as descriptive of general forms, may be added certain other characters or habits ; such as the tinted, or those which impart a solemn grandeur or richness, at tlie sea- son of fading, in our early autumn or winter months. Feathery and light branched trees or shrubs, adapted in a special way to the vista or glade, rock-shrubs and trees, those adapted to the banks of water; climbers, creepers, twiners, berry bearers, and variegations ; witli the coarser and more rustic-looking things, as leading to or connected with the woodlands, the fields, or the moor. I will now point to a few trees and shrubs in each of the classes, begging it to be understood that they may be either old or new, their suitability alone being the assumed ground of merit. Round or Flat-headed Section. — Foremost, " the gnarled and unwedgable Oak" — everybody's favourite. Here we have one of IN CERTAIN TREES AND SHRUBS. 195 the finest contributaries to a bold sky outline — in age exliibiting broad and heavy masses of foliage, disposed in well defined, abrupt, and even angular breaks ; added to which a tortuous and rugged bark — a bold relief amongst trees and shrubs of tamer character. The Beech, too, a tree for the park, the grove, the glade, or the vista. The Sycamore, which, although when young, is of no significance, attains a character in age frequently of much consequence to the scenery where it is situate ; the foliage in this case running into heavy masses, with deeply indented breaks in the outline. The Scotch Fir in age frequently attains a most picturesque appearance. In this section we have such trees as the Elm, the Lime, and various others. Pointed or Spiry. — Such as the Lombardy Poplar, the Taxo- dium sempervirens, Douglas Pine, Larch, Silver Fir, and several other Conifers, with the beautiful Cryptomeria, and many orna- mental shrubs. Trees and Shrubs of this habit are finely adapted for relieving the monotony of a heavy sky outline. What a charming effect is produced by even a group or two of the Holly- hock, peeping forth from amongst a heavy mass of flat-headed shrubs ! The Lombardy Poplar too : who has not seen and admired this tree, rising in the distance in conjunction with the steeple of some time-hallowed church ? This is indeed a most important section. If I remember right, Mr. Repton affirms that spiry trees are well adapted to the Grecian style of architecture. Columnar. — Here are many admirable things, particularly suitable as accompaniments to buildings. For the margins of promenades, terraces, or indeed any long, straight, and formal walks or lines — the corridor, balustrade, &c. — they are con- sidered well adapted. I need only point to the Irish Yew, Arbor vitse. Red Cedar, with some of the members of the Juni- perus and Cupressus families, as peculiarly of this class. Fastigiate. — There are some singular-looking things in this section ; as for instance the upright or Cornish Elm — indeed, some of the Conifers may be placed here. There has been some difference of opinion as to the use of the Lombardy Poplar, which is perhaps more of the columnar character ; but I think any one going from London to Richmond by water must be struck with the extraordinary effect produced at some villas on the banks, in the grounds of which the Lombardy Poplar, the Cedar of Lebanon, and the Weeping Willow may be seen in close combination with buildings of modern style ; the whole producing a most striking picture ; such forms powerfully con- trasting with the beautiful river to complete the scene. Horizontal. — The ancient Cedar of Lebanon may here be placed foremost : too well known to require description. The Cedrus Africanus will probably stand in this class ; and that VOL, VII. P 196 ON STYLE AND EXPRESSION ponderous and dignified-looking tree, the Araucarla inibricata; the Silver Fir, and indeed several Conifers belong here, which altogether is a most important class, especially witli reference to architectural lines and forms. Weeping Kinds. — First the old Salix Babylonica, or Weeping Willow, which may stand as the type of this class of trees ; albeit we have such graceful things as the Cupressiis funebris, the Deodar, the Hemlock Spruce, &c. ; even the Birch in some of its best humours swells the list, which, if space would permit, might be enlarged with many a goodly candidate. Who would refuse the Deodar and the Weeping Willow a place contiguous to water scenery ? The latter is so much at home in such a situation, that an ornamental piece of water in a pleasure ground is scarcely considered complete without it. Here previous associations and individual aptitude combine to press this time-honoured tree on the notice of all lovers of the graceful. Having thus given a hasty sketch of character in trees, a subject which, if done justice to, would fill a book, I may now be permitted to point to a few trees or shrubs, which, although possessing much character, may not fall in strictly with any of the classes here assumed. Conifers in general : it is almost superfluous to remark that they possess capabilities of giving quite a new tone to British scenery ; not that they will by any means cause us to part with our majestic Oaks, our Beeches, &c. On the contrary, they will add power to existing groups of deciduous timber trees, by depth of contrast ; and combine as it were the freshness of spring with the gloom of winter. Amongst these the Deodar seems by general consent to occupy the very first place, based upon a double consideration ; its exceeding great beauty as a tree, and the well known durable character of its timber. Another capital feature belongs to it, the power of its leader to resist frost or cutting winds. No person on first observing its graceful and delicate-looking leader, growing so late in the autumn, could suppose that it could remain unscathed through a severe winter. It is moreover the most manageable Fir I have seen, as to habit ; it would be easy to keep it in a dwarf state for many years. It is thus adapted to rock work or other rustic affairs, where pendent forms are employed. Next the regal-looking Araucaria — a tree for palaces. Cryptomeria, too, and the Douglas Pine, and then the genera Cephalotaxus, Libocedrus, Juniperus, Taxodium, Cu- pressus, &c. What a rich group ! Any painter who, by antici- pation, could produce a landscape on canvas, such as will be obtained in Britain in some twenty or thirty years hence by the IN CERTAIN TREES AND SHRUBS. 197 use of these fine things, would perhaps give a greater impulse to planting than all the advertising of the tradesmen. Tlie selection of trees and shrubs possessing autumnal tints is by no means an unimportant part of the planter's business. When the gloom of winter threatens — when the aspect of our gardens becomes totally changed by the general decadence of the floral tribes, then the bounteous hand of Providence, by a gracious compensation, " lights up " the woodland, the grove, and the shrubbery by those delightfully various and ever- changing tints which all who can appreciate the beauties of the landscape so much admire. This is a numerous section, and any one who would watch and carefully classify them would do planters a real service. I may just observe, that the most glorious tints I am acquainted with are those of the Liquidamber, the old yellow Azalea, and I am tempted to add, although somewhat out of place, the true West's St. Peter's Vine. The Oak family are not poor in these things ; the old Merry tree is sometimes beautifully tinted ; so is the Corylus atropurpureus, the Hippocastanum, and a host of others, including pure yellows, as the Tulip tree, &c. To these may be added for their rich tints our coloured stemmed shrubs, as some of the Dogwoods. The Berried race may also be glanced at. Foremost the old Holly, associated in the mind with the Christmas festivities of centuries, and outdoors second to none in the richness of its embellishment, or as shelter, \yhether in the shrubbery, the field, the park, or the forest. Next the sombre Yew, with its funereal associations, combining massiveness, dura- bility, and hardihood. The Arbutus, Juniper, Leycesteria, Snowberry, Ivy, Mahonia, the Garrya, Euonymus, &c. The Variegated section is by no means meagre or inapt for decorative purposes. Materials also for rock work, or for impart- ing a wilderness character, undergrowths and climbers ; and lastly, as a consideration worthy the close attention of every one engaged in ornamental gardening, our very early spring flower- ing shrubs or trees, and our very late ones. Amongst the former I would point to the old snowy Mespilus, tlie Almond, Ribes, the Corchorus, Chimonanthus, Cydonia japonica, Mezereon, Cornelian Cherry, Weigelia, Forsythia, &c. Amongst the latter, the old Althaea frutex, Erica herbacea, Clethra, Arbutus, Escallonias, Laurustine ; and lastly, the old Glastonbury Thorn of legendary fame ; and difficult it is to know whether to class this with the old year or the new. Sketchy as the present remarks necessarily are, as applied to a subject having such wide bearings, it may be seen by those unacquainted with our trees and shrubs, how rich England is in materials for decoration, at whatever period of the year, or what- p 2 198 SOME ACCOUNT OF A NEW LEVEL. ever the style : and I may be allowed to express a hope, that all intent on beautifying their gardens, parks, &c., will take into consideration the propriety of paying a due regard to the habitudes and adaptabilities of trees and shrubs. XIV. — Some Account of a Neiv Level. By A. Forsyth, C.M.H.S., St. Mary's Church, Torquay. (Communicated April 28, 1852.) I NEED not say one word on the importance of the plumb-rule and level ; they are essentially necessary in ground-work, and indeed in all the operations of horticulture they play a promi- nent part. Persons employed in other branches of industry have imple- ments peculiar to their trades : the cooper would not be able to do his work with the cabinet-maker's tools, and the mason would be puzzled to keep his work right with the surveyor's swing level and graduated staff. In the various divisions of labour, therefore, every class clings to its particular character of tools, and as new branches are introduced fresh implements must be had. Having been accustomed to gardening from my infancy, I may take some credit at this time for knowing what tools may be required for the ordinary operations of horticulture ; and, not to tire the reader with a useless list, I will confine my observations to the point at issue, and state what difficulties I have expe- rienced in getting things true to the horizontal and the ver- tical lines. For example, we shall suppose that five tliousand stakes of various sizes, from 4^ feet to 10 feet in length, are to be inserted in the ground by the gardener in one month, viz. the month of May, as props for Hollyhocks, Dalilias, Roses, &c. ; these stakes, being neatly planed and painted, are stuck up quite naked, a forest of green sticks, and they are contiguous to the main-lines of walks, where highly educated parties are constantly passing: now, I would ask, could a handy man, with rule of thumb, do this neatly ? He could not. This is no fan- cied case ; I have tried it with good workmen, I have tried it myself ; it could not be done. I had to get the plummet, and stand by the pole, and first set it right from south to north, and then from east to west, and this in windy weather is not a very straightforward job. Again, in plunging Pine-apple pots in a bark-bed sloping to the south, it is not very easy even for a practised eye to put them level, and, if they are not, the water will flow over one side and leave the other dry. I need not adduce further instances : these two examples may suffice, as they are taken SOME ACCOUNT OF A NEW LEVEL. 199 from real practice in the ordinary routine of flower and kitchen gardening. The Level I have invented combines the plumb-line and the level in the same instrument, and that instrument so small as to be got into the pocket ; with it a stake may be set upright in any weather, and the vertical line determined instantly ; ten observations may be made with this tool whilst the mason's plumb-rule is being adjusted to make one ; and the same may be said of the horizontal line, for it is no easy matter to get the spirit-level accurately adjusted ; and that most valuable tool, the mason's level, is miserably slow in its movements in all weathers, and in windy weather it will not give a true line at all, whereas this little implement not only tells instantly when the bed is level on which it lies, but tells how far it is from that point in case the bed be an inclined plane, thereby giving a regular fall to drains, &c., where inclined planes are wanted. The Level is constructed upon the principle of the hour-glass, and, by a particular character of sand, the lines are given very fine. The accompanying sketch will give an accurate idea of the dial of the contrivance. No scale is needed, as the sketch is the full size of the instrument. 200 SOMK ACCOUNT OF A NKW LEVEL. The first was made three years ago ; the subject lias been carefully digested since, and it is to be hoped tliat tliis will prove a most valuable implement in the ordinary operations t>f horti- culture long after the inventor has been forgotten. In appearance the instrument is something like half a brick. Its dimensions are 3^ inches X 3^ x ^^^ The diagram represents the face of it, in which two cavities are cut out so as to form each a quadrant of a circle, as appears by the degrees marked. Some fine sand, like that used for hour- glasses, is enclosed in these cavities by glazing in front. The sand falls from the upper part through a small hole into the lower, as in the conmion hour-glass. 'J'he particles of sand fall so continuously that they form in appearance a tolerably fine line. If the instnnnent be placed upon anything that is truly horizontal the sand will fall, as a plunnnet would, from the small hole in the centre, to 90^. But should the instrument be placed upon anything that is not level, the particles of sand will still fall perpendicularly, in accordance with the law of gravitation ; but the apparently continuous line of falling sand will not be direct from the centre to 90'' ; it will deviate from the latter point in proportion as the object on which it may be placed de- viates from being level. If it sliould be placed on the slope of a rafter making an angle of 20^ with the ground, then the sand will fall from the centre to 20'-' from the point at 90°. Again, if the instrument be placed with its side against an upright post or stake, the sand will be seen falling in a line from the centre to 90° ; if the post be not perfectly ui)right, then the perpendicular stream of sand will be seen to fall on points more or less distant from the line at 90°, according as the post is more or less out of the perpendicular. In using this level for draining purposes, or for other inclined planes, such as setting a melon-frame up to the sun so that its roof may be of the same pitch as an adjoining pine-pit, first put the level upon the rafter of the pine-pit or other inclined plane to be copied, and mark the sand line, which we shall suppose to indicate 75° ; then put the level on the rafter of the melon-frame, and prop the frame until the sand line indicates the same angle. And so of drains or other inclined surfaces, putting the level on a piece of wood with parallel edges (a common straight edge). The level, if made of our Devonshire madrepore marble, is expensive ; but, for ordinary purposes, the instrument does very well made of oak or other well-seasoned wood. ON GARDEN WALKS. 201 XV.— On Garden Walks. By R. Glendinning, F.H.S., Member of the Royal Agricultural and Botanical Society of Ghent. (Communicated May 15, 1852.) The comfort and enjoyment of a garden, especially in our moist climate, depend in a great degree upon the condition of its walks ; for unless these are smooth, firm, and dry, they can scarcely be passed over during a large portion of the year except in very fine weather, and rarely indeed by invalids, more especially at those times wlien gardens are most enjoyable, viz. mornings and even- ings, as well as after showers. A main feature in the formation of a garden should therefore be walks so made that they could be walked on in all weathers with comparative comfort. la forming walks, the first thing is to determine the position of tlie verges. In doing this it must be kept constantly in view that in nearly every case, whether on level ground, ascending or descending inequalities of surface, the verges at right angles across the walk sliould be on the same level, and for the follow- ing reasons. First, each half of the walk will receive only its due proportion of rain, which tends in so many instances to dis- figure and disturb the surface ; secondly, walks so made will be found more agreeable to walk on than if they had an inclination from one verge to tlie other ; and lastly, by this arrangement the eye of taste will neither be offended nor annoyed. The mind will receive that kind of satisfaction which it derives from looking at a perfect architectural elevation, and to efl^ect this ap- pears to me equally important in matters of gardening as in those of building, especially where the utmost refinement in the art is aimed at. The next point to be considered is to make provision for carry- ing off water, and this should be so contrived as to meet the maximum amoiuit of our atmospheric precipitations, particularly where the inclinations are rapid and of great length ; on level surfaces and when the natural soil is loose and friable, this w ill not be so urgent, provided the walks are otherwise properly formed. Tlie best material to use for conveying the water will be the earthenware tubing now so well known everywhere, and of a diameter in proportion to the width of the walk and the length the water may have to run before it is discharged. This will be easily determined by persons accustomed to such mat- ters, or at all acquainted with draining. The most convenient place to lay the tubing will be in the centre of the walk, with communicating tubes to the sides, where square cesspools about 202 ON GARDEN WALKS. 9 inches square and 18 inches deep, built in brickwork, should be formed to receive the water and sand or other earthy matters wliich may be carried along with it. Tlie water will pass into the drain near the surface of these cesspools. A grating fitted in a stone frame must be placed over each cesspool, so tliat by lifting up the grating the cesspool may be readily cleaned out ; where the walk takes a precipitate fall, and for a considerable distance, provision must be made for the water to run in before it reaches the gutters, without allowing it to rut the gravel. This can be effected by means of surface guttering both sides of the walk with tiles made for the purpose, or where sea pebbles abound these may be used with good effect. One of the main points which conduces so largely to the beauty of a garden is the perfect keeping of the walks, and unless precautions are taken in their first construction to guard against those natural and un- avoidable causes which disturb the surface, there must be con- tinual repairing and unsightly patching, producing at best a most unsatisfactory result, which a little extra trouble in the first instance would have effectually obviated. The material of which walks should be formed is a subject de- pending in some measure upon the geological formation of the neighbourhood ; for where the most fitting material is not readily accessible, few are inclined to incur the expense of distant car- riage, although railroads have in many instances assisted in this matter. In nearly every part of the country some kind of rough and hard material can be had, such as broken stones, rubble, or even clinkers constitute a good foundation. "Walks for ordinary purposes do not, as some imagine, require a great depth of bot- tom beneath the fine gravel which constitutes the finish ; 9 inches in most cases will be found ample. This foundation has been mistaken by many for drainage, but no such thing is meant, as the surface of the walk when finished ought to carry the rain to the sides ; as little as possible should be absorbed by the gravel, because where there is great traflfic, in a short time the walks would become a complete puddle, and hence the necessity of ren- dering the surface impervious to wet. This has induced many persons to cover the tops of their walks with concrete or asphalte, but when good gravel can be procured at a reasonable expense, I think under all circumstances it is to be preferred. It is more congenial to our feelings and harmonises better with the sur- rounding scenery of the garden. Under particular circumstances necessity will suggest other expedients, but then let necessity also justify their use. Two inches of fine screened gravel are sufficient wherewitli to cover the surface as a finish to the whole, and where this is found to be an expensive article, one inch ON GAKDEN WALKS. 203 carefully laid on will suffice. Therefore when the cost of a cubic yard of gravel is known, it will be easy to ascertain ex- actly the expense of coating any given extent of garden walks. I shall now direct attention to the form which the surface of walks should have when finished. This I apprehend has been but little understood by those who have attempted to lay down rules for our guidance, inasmuch as certain requirements, as well as peculiar situations, have a considerable influence in the matter. Perfectly level walks, like the floors of a house, are not only more agreeable to walk on, but they are also strictly in conformity with good taste in geometrical gardening, where sculptural and architectural decorations prevail, and indeed in all kinds of gardening ; the only plea that can justify a deviation from this rule is, that our garden walks are exposed to the atmosphere, while the floors of our houses are protected. To render walks available therefore for the purposes for which they are introduced, becomes a matter of primary import, otherwise the level rule might be made absolute, as is the perpendicular in the elevation of a building. Now on terraces surrounding buildings, and in elaborate parterres similarly or identically circumstanced, the nearer the walks approach a level surface, just in proportion will a mind imbued with taste and a correct eye appreciate their execution. AYalks so laid down are only available in perfectly dry weather. Situations which are elevated, either naturally or artificially, and thus rendered perfectly dry, afford the best oppor- tunities for a close approximation to this rule. It must be stated also, that even in situations where the traffic over them is con- siderable, they will soon cease to afford either comfort or enjoy- ment. Necessity, therefore, compels the adoption of a surface less or more convex as the circumstances may appear to demand. Walks in private gardens are little used in wet weather, and therefore they are not likely to be much disturbed at such a period, which is the time above all others when excessive traffic breaks up their surface. The water does not pass off, but is held in the loose gravel until they become almost impassable, which is in fact the case in all public walks so constructed, as was formerly notoriously exemplified in the Society's Garden on wet exhibition days previous to their being altered. It therefore becomes clear that situation, and the uses for which walks are required, should materially influence the operator as to the proportion of convexity which they should receive. Some entertain an idea that walks should only maintain a very subordinate position in garden arrangements, that they should be kept as much as possible out of sight, and that their appearance 204 ON GARDEN WAI.KS. should be only a matter of necessity ; but such notions are only applicable to garden wildernesses, and have no relation to gardening as an art of design. It might be urged, with quite as much consistency, that tlie door of a mansion should be hidden or obscured, being only a means to an end. Those at all ac- quainted with the classical and decorative style adopted in some of the best examples of Continental gardening will readily under- stand this, where indeed walks constitute quite as important a feature in geometrical gardening as windows do in the elevation of a building ; they illustrate in fact a material part in the composition. Divest a garden of walks, and the main lines which mark out its form and proportions are destroyed. As roads are to a country evidences of the degree of its civilization, so walks in a garden are indications of the amount of artistical skill brought to bear upon it. Take as an example a garden planted with all possible taste, and with tlie most decorative flowers which can be selected, and I would ask what satisfaction could such an arrangement produce in a mind cultivated and refined by a high social position, or how could such a garden be enjoyed ? Walks contrasting with turf and flowers, conduce to a harmony in the composition which the two latter of themselves never could accomplish. Where artistic gardening has been carried to the utmost limits consistent with propriety and good taste, and where numerous architectural and sculptural embellish- ments have been introduced, walks are then frequently elevated above the general level. To accomplish this, stone edgings have in some instances been used, and in others, where the style admits of more elaborate embellishment, walls of solid masonry as edgings have been employed in order to raise the walks above the level of the garden, so that the eye may look down upon the flower beds, and more perfectly view the general arrangement and design. It has been attempted by some to lay down rules as to the direction which walks should take, and also their width ; such, however, can be of little service, as local circumstances must nearly in every instance determine this. It may be stated, however, as a principle, that where walks take a straight direction and are level, or upon a uniform inclination, the width must bear a relative proportion to the length ; as for example, a walk 10 feet wide may look very well if the length does not exceed 200 feet, but supposing it to be 2000 feet, the proportion would then be entirely destroyed. These, and other matters of detail, must be left to the operator. rivers' S SEEDLING ELIZA STRAWBERRY. 205 XVI. — Note on Rivers's Seedling Eliza Strawberry ; and on a mode of Potting. By R. Thompson. Three plants of this were received from Mr. Rivers, October 8th, 1851, in order to ascertain the effects of a particular mode of potting the runners. This consists in ramming the soil in the pots with the view of condensing in the latter a greater quantity of nourishment for the plants. The above were placed along with the other strawberries potted in the usual way for forcing. Under the same circum- stances the Seedling Eliza ripened about a fortnight later than Keens' Seedling, therefore it cannot be recommended for early forcing. Tiie fruit is middle-sized, somewhat conical ; flesh solid, with the flavour of Myatt's Eliza ; the scapes and foot- stalks very hairy. It is likely to prove a rich-flavoured straw- berry in the open ground. Hard potting produced no beneficial result. Plants of Keens' Seedling potted in the usual way made a better growth, and yielded a larger crop ; and when turned out of the pots after forcing the roots were sound ; but many of those in the hard potting were not so. If we put into each of two pots an equal quantity of the same kind of soil, and if by ramming we can make one pot contain the same quantity of soil, and of course all the nourishment that was in the two, it would seem to follow that a plant would thence derive a double amount of nourishment, and make a proportionate growth. But the experiment proves that such is not the case. It shows, on the contrary, that a large quantity of nourishment may be unavailably contained in soil that is too compact for the roots of certain plants to penetrate. This is more especially the case as regards plants in pots, because they are induced to make finely divided roots, like a net- work, between the sides of the pot and ball of earth. All below the surface, the ball is often completely enveloped with these very fine roots, which bind it more and more, whilst they seem to have lost the power of re-entering it. They assume the character of roots formed in water, and losing the stronger form which those have that travel in the soil, they neces- sarily avoid the latter, if not of a very permeable nature. The roots of large trees will traverse a great extent of very firm soil, and will sometimes even upset walls that have shallow foundations ; but let these powerful roots dip into a well, and then their earth penetrating adaptation ends. They form there, a mass of thread-like roots, that may be bundled up like a quantity of rope-yarn. In like manner, but in a finer degree, the roots of plants in pots form fibres in the moist easy medium o. extension along the insides of the pots; and if it is desirable that 206 HOW TO FORM AN ASPARAGUS BED. they sliould not in this way almost entirely desert the soil, it is certainly necessary that the latter should not be rendered, by any means, too obstructive to their ramifications throughout its mass. I may take this opportunity of adding a word respecting CuthilVs Black Prince Strawberry . Runners of this sort of Strawberry were ordered to be potted last summer for the purpose of trying its merits for forcing. The plant is naturally of slender growth, too much so for throwing up a sufficiently strong scape in forcing. Its setting is very preca- rious ; but it is a little earlier than Keens* Seedling, yet it is in every other respect so inferior to the latter, that it cannot be recommended. It has neither size, beauty, nor flavour to render it worthy of room in a forcinor-house. XVII. — How to form an Asparagus Bed. By Peter Kendall, Esq., F.H.S., of the Marine Villa, Aldborough, Suffolk. On forming a new vegetable garden at my residence here about four years since, 1 made of course a new Asparagus bed, and finding it quite answer my expectations as to its productive- ness and quality, and the plan I adopted being original, I send you the particulars of its formation. I set out my bed as follows : — 60 feet long, 5 feet wide, 4 feet deep. The earth was all taken out and laid on one side the bed ; I then placed at the bottom 2 feet deep of salt ooze, from the banks of the Aide : 1^ feet deep of the river weed (a long grass) : 2 feet of the best vegetable mould was then placed on the top, and the young plants set out at 18 inches distance, all over the bed. Note by the Vice- Secretary. — It will be obvious that the me- thod of proceeding adopted in this little experiment was founded upon tlie most just conception of the nature of the Asparagus plant. Deep rich loose soil for its roots, salt in moderation, and the crown of the plant only just buried in earth, produced, as might have been expected, heads of the finest Asparagus possible, green, succulent, excellent in flavour, and in no respect inferior to any that has been seen by the most experienced gardeners. PROTECTION OF FEUIT TBEES AGAINST WALLS. 207 XVIII, — A Note on the Protection of Fruit Trees against Walls. By R. Thompson. With reference to the protection of Fruit trees, it may be of utility to state the means employed in the late unusually severe weather, and the results. In March the nights were generally frosty ; the wind during twenty-four days came from north-east or east, dry and cold, so that vegetation was fortunately much retarded. In April, the wind still continued to blow from cold quarters, and the dryness of the air increased so that there was not sufficient vapour to form clouds to prevent the escape of heat by radiation ; and the consequence was, that on the nights of the 19th and 20th of April, the thermometer indicated, respectively, 12° and 11° below freezing. According to the register kept at the Garden, this was lower than had been registered for twenty-six years so late in April ; and it appears from Howard's " Climate of Lon- don," that so low a temperature has not occurred so late in the season within the last fifty years. Peaches and Nectarines were in full blossom at the time. In the end of March, coping-boards were placed along the wall, and also a net over half of it, and straw screens were placed against the trees on the other half at nights. But previous to the severe nights abovementioned, the net was removed, and straw screens, deemed better protection, were substituted. These screens consisted of one length of the straw fixed on twine stretched between inch- square 6 feet long training-rods. The screen was kept stretched by placing the tops of the rods a a against nails in the wall, whilst the lower pointed ends were in the ground. During the day the screens were rolled up and laid at the bottom of the wall. So far as these extended, the blossoms were sufficiently pro- tected ; but all blossoms on the fronts of the shoots above them were destroyed. Some, however, that were on the sides of the shoots, and leaning close against the face of the bricks, derived as much heat from the latter as kept them alive. On the whole a fair crop has been saved. On the Pear walls the blossom was abundant and mostly expanded. Coping-boards were procured for a considerable portion of the walls that were originally furnished with brackets. In addition to the coping-boards a net was suspended in front of the trees on the east aspect ; and elsewhere straw screens were made to project from the top of the wall. Under these the fruit on the upper branches near the straw were saved, but those towards the bottoms of some of the trees were much injured. With few exceptions, however, the crop of pears on walls will be good. A glazed Peach frame was covered with mats ; but, notwith- standing this precaution, the blossoms were in great measure cut off. 208 niOTECTION OF FRUIT TREES AGAINST WALLS. The iron and glass protecting frame by Messrs. Cottam and Hallen was not completed wlien the severe frost was experienced. The foliage under it is at present (June 1) very healthy, and does not appear checked like that exposed to the cold nights in the end of May. From what has been observed, the facts are ascertained that a thin straw screen will protect peach-trees in blossom from the effects of twelve degrees of frost ; that coping-boards will be sufficient for about four degrees ; that a conuuon net (not woollen), aided by coping-boards, was insufficient compared with straw screens ; that sashes, in a nearly horizontal position, covered with a mat, but with a 3-inch opening at the back of the frame, and a perforated zinc plate in front, were likewise insufficient, the peaches suffering as much, or more than those on the open wall with coping only. Straw having proved so efficient, probably owing to its being hollow, and, confining in its interior a quantity of air, a slow conductor of heat, it seems desirable that it should be manufac- tured so as to preserve, in great measure, its tubular form, and have a neat appearance. ORIGINAL COMMUNICATIONS XIX. — Recent Researches on the Respiration of Plants. By M. Garreau, M.D.* In the course of my first experiments upon the absorption by and exhalation from those surfaces of plants which are exposed to air, I had often noticed that the leaves and green parts of plants, when acted upon by the direct rays of the sun, gave out very sensible quantities of carbonic acid. This fact, so apparently opposed to the ordinary notions re- specting the functions of leaves, struck me very forcibly, espe- cially as it is also precisely under the direct influence of the sun that the leaves and young shoots of plants reduce the carbonic acid in the atmosphere with the greatest rapidity and retain the carbon. Some more recent experiments made in the latter part of 1850 {Annalesdes Sciences Naturelles, 1851) not only confirmed my former observations, but showed that expiration of the acid gas takes place equally in the shade if the temperature is sufficiently high to cause the vital juices of the plants to move. These ex- periments being made towards the end of the summer, did not enable me to ascertain whetlier the phenomena which I have men- tioned were affected by the age of the plants or the seasons, and for the purpose of acquiring further information upon this sub- ject the experiments about to be described were made. 1. The Action of Buds on Atmospheric Air. Buds, like young plants, represent individuals at a time when tlie living substances containing proteine are, comparatively speaking, much greater than at any other time of their existence, and it became interesting to ascertain whether the activity of their respiration bore any ratio to the quantity of their animal matter. In order that the results might be as exact as possible and easily compared with eacli other, the degree of the develope- ment of the buds, and their weight both when fresh and dried, were noticed with the greatest care, as was also the quantity of air in which they respired, wdiich was always kept as nearly as possible at the same temperature during all the experiments. * Annales des Sciences Naturelles, xvi. 271. VOL. VII. Q 210 KECENT RESEARCHES ON THE RESPIRATION OF PLANTS. The buds, selected from amongst the finest and cut witli a small disc of the branches bearing them, were made up into a little bundle in such a way that the small discs formed a support which could be plunged into water and yet leave the buds un- wetted. A cup of water with the buds thus arranged within it was placed under a graduated bell-glass, the inside of wliich liad been previously covered with a concentrated solution of hydrate of potash in order that the carbonic acid might be fixed at the moment of its escape ; the bell-glass and the cup within it were then put in a dish of water placed near the window of a room the temperature of which was kept at 15° or 16° C during the twenty-four hours for which the experiment lasted. The buds did not suflfer the least under these circumstances, and whilst under the glass their little scales expanded, and the size of the small leaves lying immediately below the scales of the strongest buds, as those of the Mihes, Tilia, Staphylea, &c., was doubled. The diminution of the volume of air was noted separately, day and night ; the temperature being the same, this diminution very nearly expressed the volume of carbonic acid given out ; for it had been previously ascertained that the air was condensed by the buds only to a very insignificant extent. The experiment over, the buds were separated from the small discs which supported them, weighed when quite fresh, then dried for twelve hours at a temperature of 110° C, and weighed dry. The annexed table (p. 211) shows that in equal times and tem- peratures buds consume on an average twice as much carbon as fully developed leaves. This accounts for the fact, that in the buds and their vicinity M. Dutrochet was enabled to determine in a most marked manner the temperature peculiar to plants, and to generalize the discovery of their paroxysm made by M. Ad. Brongniart. If the numbers in the three last columns be compared, it will be seen that as a general rule, and under the conditions men- tioned, the buds exhale about eight times their volume of car- bonic acid in the twenty-four hours ; that dried at a temperature of 110° C. they lose on an average five-fourths of their weight, a loss which represents their water of composition and of vege- tation, and that then the carbonic acid exhaled is to the volume of their solid parts as 40 to 1, if we admit, as we may witli con- siderable accuracy, that in this state their density is the same as that of water. Theodore de Saussure was satisfied with establishing the re- lation in volume which the carbonic acid expired by leaves bore to their weight wlieii fresh. In our opinion no exact results EECENT RESEARCHES ON THE RESPIRATION OF PLANTS. 211 1 • 1 • Jl -r. a> CO >-. oi >-i 3 9 -^ P 1 -3 ^ O 3 73 ^^ S -M X Si 'P. CD C OJ M H 13 > -3 -3 ci ai J3 O si X day.

Besides, as soon as an attempt is made to determine the relations which exist between the matters containing proteine and the oxygen transformed by them into acid gas, all comparison is liable to lead to erroneous conclusions unless based exclusively on the weight of the organ dried at a temperature which is kept uniform in all tiie experi- ments ; for this reason the buds upon which the present ob- servations were made were dried for twelve hours at a temperature of 110° C. These first experiments upon the respiration of buds were scarcely finished when the temperature fell rapidly, and their vegetation remained stationary until the 15th of April, when it again I)ecame very active, the temperature in the shade having risen to 15° and 18° C. On the 20th of the same month each of the buds of the trees previously examined had made a young shoot, and these shoots were in their turn taken and made up into little bundles, of the same weight as that of the bundles of buds before mentioned, and placed under the same conditions as the latter. The results were very analogous to and sometimes identical with those obtained from the buds ; this will be seen if the numbered examples in the following table (p. 213) are compared with the corresponding numbers in that before given. If, instead of comparing the partial results given in this table, we take the mean as term of comparison, the differences which will be then found to exist are so small that we feel warranted in stating that the buds and young shoots which succeed them, con- sume, under the same conditions and for equal weights, an equal quantity of carbon : that is to say, that the activity of their re- spiration is the same. We have in effect, — Table the first : 69 grammes ; fresh buds = 1 2-55 grammes ; dry buds = 240 c.c. carbonic acid. Table the second: 66 grammes; young shoots= 12-85 grammes; dry shoots = 266 c.c. carbonic acid. 2. The Respiration of Young Plants. Seeds, like buds, contain the fundamental rudimentary organs of the plants which they spring from, and are provided with a large proportion of living azotized matters : thus it is that during their germination, if collected into masses, they consume their own carbon, and give out sufficient heat to affect the commonest thermometers. This function, already so active at the commence- ment of germination, goes on with still greater intensity when the seeds, disengaged from their episperm, spread out their cotyle- UECENT RESEARCHES ON THE RESPIRATION OF PLANTS. 213 CO o o >o o o ^H I— I CO o O '-I •ajBjs HS3JJ o o o o ^Oi r- O t^ CD o 05 CO o CO •jiy JO 9011^0^ i30 O O O .O O O O u t— t^ t— t^ o o o o 1:^ t- o o o o o o t^ lr~ t~ o o CI o o •daiUBaadcaaj, o o C^4 o (M CO e ^ 9 o. ^ o5 s o ^ a; .8 2 s ^ J o 5: -c r'^ "^ e ^ ^ S to ^ Cq ft, tn ^ IB Sn O 'S O ?i o .^ o cq k; O e-^ »o CO 00 05 r^ 2 K ^ 214 KECENT RESEARCHES ON THE RESPIRATION OF PLANTS. dons to come into still closer contact with the air whicli sur- rovinds them. To measure the activity of the respiration of young plants, some seeds were sown, from the 12th to the 16th of April, in very fine siliceous sand moistened with rain-water, and placed in glass capsules. After germination the episperms were carefully re- moved, and the glasses mth the vegetating plants were placed under a bell-glass as before. After having carefully measured the diminution of the volume of air, the young plants were taken with tlieir radicles, washed in a little stream of water to get rid of the sand attached to them, wiped, weighed, then dried at a temperature of 110° C, and weiglied again. The following table shows the conditions under which the experiments were made, and the results obtained from them : — Names of Plants. Dates AprU. 3 fl 0! lb rs a; Observations.

Comparing the volume of acid produced with that of the plants containing their water of vegetation, the proportion will be found to be that of 6 to 1, or thereabouts; but if the comparison is made with the weight of the organic matter dried at 110° C, it will be seen that in reality they consume, in the same space of time and in Ihe same conditions, a much larger quantity of carbon than is consumed by the buds ; and this might have been expected, inasmuch as the seeds, at an early stage of germination, part with tlieir episperm, which is very poor in animal matters, and their living azotized substances, which form the seat of the respiratory action, are thus relatively increased. In a former paper {Atm. des Sci. Nat., 1851) I had collected some proofs which are increased by the new facts just related ; for now as then it may be seen, on consulting the analytical results given hereafter, that the organic azote contained in the buds, the young plants, and the leaves is abundant in proportion as tlieir RECENT KESEAECHES ON THE RESPIRATION OF PLANTS. 215 respiratory activity is well marked, or, in other words, and other circumstances being the same, as the oxygen consumed in a given time is greater. In order that the results might be as trustworthy as possible, the accurate tests pointed out by MM. Warentrapp and Will were employed in the first instance, and afterwards the not less accurate one of M. Millon was used to correct any error that might have escaped notice.

Although the exhalation of carbonic acid under the influence of the solar rays at a certain temperature cannot be doubted, it must nevertheless be admitted that in the young shoots and leaves there exist two simultaneous and opposed actions, one of combustion, the other of reduction, and that the accumulation of carbon in plants can only be explained by the greater effect of the latter as compared with that of the former. New experi- ments upon this matter were however required in order that this curious subject might be satisfactorily understood, and they have accordingly been made. Tiiey were suggested by the following- consideration : if plants exhale carbonic acid at the very same time that they reduce it, they ought incessantly to reduce that which they give oflf if they are in a confined atmosphere. If then two branches covered with green leaves, of tlie same plant, of equal ages and weights, were placed in two equal atmosphera*;, one with and the other without a solution of baryta, the glass with baryta-water ought to contain more carbonic acid than the other, inasmuch as the gas would be fixed in the former, and thus not be liable to be reduced by the leaves. The following table shows the results obtained by actual experiments, and the conditions under which they were ob- tained. 218 KECENT RESEARCHES ON THE RESPIRATION OF PLANTS.

These experiments, made with the greatest care, sliow to demonstration that not only the carbonic acid exhaled whilst the plant is exposed to the sun is to a great extent reduced under its influence as the gas is given off, but that this also takes place in the shade even on a cloudy day : this may explain the oc- casional rapid growth of plants during a long succession of dull rainy days in the climate of Lille. The above experiments were made in the apparatus already described, and in the examples num- bered 1 the quantity of gas was ascertained by means of baryta- water introduced through the safety tube as soon as the experiment was over. It is scarcely necessary to remark that in the examples numbered 2, the whole of the gas given off is not represented, some of it having been reduced by the leaves, the surface of which was much larger than that of the baryta-water at the bottom of the vase. It must also be observed that, as is shown in the following table, experiments made in the sun, and in a high temperature, give a larger amount of carbonic acid.

The influence of temperature upon the respiration of plants is not doubtful, for the Fagopyrum deprived of light, and at a temperature of 35° C, gives out twice as much carbonic acid as it does at the ordinary temperature of a summer's night. The four examples just given serve not only to show the stimulating action of heat on the respiration of plants, but they, or at least the three first, may assist in determining the quantity of carbonic acid exhaled and reduced. In short, as it has been found that the acid given off by a plant in a confined atmosphere is wholly or partly reduced, it is natural to admit that the three Fagopyra of the same weight, and submitted for the same period of time to the same tempera- ture, respired in the same manner, that is to say that they all probably formed 120 cubic centimetres of gas, of which 78 cubic centimetres were reduced by the first number, and only 54 by the second ; the diflTerence of 24 cubic centimetres being, I imagine, owing to the action of the baryta-water. This surmise must not however be considered as a decided opinion, for it may happen that in the dark all the acid produced by respiration is completely given off, whilst under the influence of the solar rays, whether direct or indirect, one part of the acid is reduced in the parenchyma of the respiring organ. I am the more inclined to think that this is often the case, because I have occasionally observed that very small quantities of acid escaped reduction. The means employed for ascertaining the reduction of acid exhaled during the day may be also used for the purpose of 220 EECENT RESEARCHES ON THE RESPIRATION OF PLANTS. observing whether carbonic aeid gas is not reduced during the long summer evenings and mornings. The following table shows the results of some experiments undertaken with this view, and they are given, though, from the small number of the experi- ments, nothing decided can be inferred.

The reduction of carbonic acid being less active in the shade than in the sun, I was curious to learn if the diffused light, occasioned by the eclipse of the 28th of July, caused an increa.se of undecomposed carbonic acid in the air surrounding the plants. For this purpose four apparatus were got ready just as the moon passed before the sun, and were examined the moment the eclipse was completely over. The experiment lasted for three hours, and the feeble solar rays were almost constantly intercepted by liglit clouds. The results obtained are given in the following table.

The sky was clear and cloudless, and the tem- perature average, but in the shade 2° C. higher than before. Names of Plants. Observations. 1. Fagopyrum cymosum .... 2. Fagopyrum cymosum .... 3.

From the above it would seem that the eclipse of the 28th of .July had no sensible influence on the respiration of plants, and that the smaller quantity of carbonic acid existing when the eclipse was over ought to be attributed to the lower temperature caused by the interception of the sun's rays by the clouds, inas- much as in the experiments made the next day the difference was greater, as the temperature to which the apparatus was exposed was greater. However, it may be concluded that the temperature being the same, tlie acid expired would have been more abundant in the diffused light caused by the eclipse ; for the reduction of the acid gas is known to be much less intense in the ordinary light of day than in the sun. If it be inquired how M. Theodore de Saussure, whilst en- gaged in his experiments on the respiration of plants, happened to overlook the fact that carbonic acid is given off by them, it can only be answered by way of conjecture that in all proba- bility he was so intent upon its decomposition by the leaves when acted upon by the sun, and upon the importance of tliat gi-eat 222 RECENT RESEARCHES ON THE RESPIRATION OF PLANTS. fact, tliat he was induced to neglect as trifling all contrary ap- ])earances ; and this is the more probable as in two instances he noticed its exhalation, without, however, doing more. It being clearly ascertained that jilants decompose carbonic acid, and that they also exhale it, we may fiiirly infer that the accumulation of carbon is explained by the predominance of the first process over the second ; and to show that this is so, the following experiments were made. A top of a young, green, and leafy stem of Fagopyrum cymosuni, w^eighing, after the ex- periment, 15 grammes, was placed in the curved part of the apparatus before mentioned, which was then carefully closed and luted ; a small caoutchouc bladder, furnished with a stop-cock, and containing 200 cubic centimetres of carbonic acid, was then fixed to a tube, so that the stop-cock being open there was a free comnmnication between the gas in the bladder and the air in the flask. After an exposure to the sun for six hours, only Yo cubic centimetres of gas were found in the flask and bladder. Whilst this experiment was going on, another, and in every respect similar piece of the same plant, was in a second apparatus with some baryta-water, which fixed 1 1 cubic centimetres of ex- haled gas. In order to ascertain whether the air in calm weather can by its carbonic acid supply the wants of a plant, notwithstanding the loss of carbon occasioned by the latter, both by day and night, water saturated with baryta and its carbonate, and with a surface of 300 square centimetres, was exposed for an hour in the open air to the rays of the sun ; the pellicle which had then formed gave, on being decomposed by citric acid, 15 cubic centi- metres of carbonic acid, that is 180 cubic centimetres for twelve hours of day. Now, the surface of the leaves of the 15 granmies of Fagopyrum was five times as large as that of the solution of baryta. These 15 grammes were then at least in the immediate contact of 900 cubic centimetres of carbonic acid during the day — i. e. 40 or 45 times more than that which might have escaped reduction during exhalation. Besides, the exhalation by the leaves is not really very great, unless the temperature in the shade is 20° C"; at a lower temperature it generally decreases, as does also the reduction, the opposite effects of which it seems destined in part to correct. Now that the existence of two simultaneous and contrary pro- cesses— namely, those of combustion and reduction — is no longer doubtful, the notions regarding the respiration of plants hitherto current must necessarily be considerably modified. Indeed it is clear, that both in the day and in the night plants respire like animals, but that this resjnration is during the day more or less concealed by the contrary process : and it was for this reason RECENT KESEAECHES ON THE BESPIEATION OF PLANTS. 223 that ever since 1849 {Ann. des Sci., 1850) I was inclined to regard what was called the respiration of leaves as two distinct processes. Plants decompose water and lix its hydrogen ; they decompose ammonia and its salts, and fix nitrogen ; they reduce sesqui- oxide of iron in solution to protoxide, and they reduce carbonic acid obtained from the soil, formed in their tissues or taken from the air. All these acts are, in our opinion, closely connected with the functions of assimilation and nutrition, whilst the con- sumption of carbon and perhaps other elements, which is the principal source of the vital heat of plants, is connected rather with the function of respiration. If we look, then, at the most evident phenomena, the respiration of plants does not differ from that of animals, and instead of tlie processes being different in flowers, leaves, fungi, &c., they are all identical, combustion of carbon and production of heat, which may itself influence the intensity of the function of respiration, where only a small quan- tity of the acid produced thereby escapes reduction. The existence of a diurnal and nocturnal animal respiration in plants ought not to be looked upon as very surprising if it be remembered that those matters whose vital properties are most manifest in plants have life, and are of an animal nature, and, it may be added, become true animals at certain periods of the life of some plants. Let us take for example the animalcules found in the anthe- rida of Chara, Nitella, Ferns, Mosses, Horsetails, Liverworts, t&c., which have been so carefully examined by MM. G. Thuret, Niigelli, Sumenski, Wigand, Derbes, Sollier, «S:c., and it will be found that their animal nature cannot be doubted, and that their origin is incontestably owing to tlie metamorphoses or de- velopenient of the living proteine substances of the cells. For my own part, I have observed them in several species of Chara, in Nitella jiexilis, and Marchantia polymorpha, and the animal nature of these beings appears to me so evident that, with all due respect to M. Siebold, I cannot help thinking that his observa- tions were made at a wrong season. Let us examine again the motion of the zoospores, discovered by Meyen, and the organization of which was described by linger in the Vaucheria clavata, and afterwards by Thuret, and the movements of the sporoides of different Fucacem described by MM. Decaisne and G. Thuret {Ann. des Set., 1850) ; and if we do not then believe the living azotized substances which move in the cells of plants to have the organization of animals (as, for example, that of the animalcules in the antheridia, or of the zoospores), we shall be at least convinced that their organizations are remarkably similar. 224 RECENT EESEARCHES ON THE KESriRATlON OF PLANTS. What is more to the point still, is that the zoospores, actually living and moving, but deprived of the cellular envelope, soon become stationary, and cover themselves with a cell which they secrete ; and though to all appearance dead under the veil wliich hides them from our view, their vitality is still retained, for they form a plant which again calls tliem into life. This curious fact deserves a most careful examination by physiologists, as it might lead to other circumstances throwing great light on the true nature of plants. There is in truth an immense difference between algals and the large majority of other plants ; but we must look for their resemblances not to form or functions of secondary importance, but to the movements and principal functions of their azotized substances. Conclusions. From the facts which have been now mentioned, we may conclude : — 1. That buds when respiring consume more carbon than the leaves, and less than plants themselves. That the quantity of acid expired is great in proportion as the quantity of living proteine matters contained in these organs is great, their weights and surfaces being equal. 2. That in the day time, both in the sun and in the shade, leaves exhale carbonic acid, the quantity of which is great in proportion as the temperature is high. 3. That the acid found in the apparatus does not represent by a great deal all the carbonic acid given off, the larger part of it being reduced after being exhaled. 4. That two simultaneous and opposite actions go on in the leaves, both in the sun and in the shade ; one by which carbonic acid is formed, the other by which it is decomposed, and that the accumulation of carbon in plants is due to the excess of the effects of the latter over those of tiie former. 5. That these two acts being simultaneous, the former ought to be considered as the respiration of plants, and the latter as more especially connected with their nutritive functions. CniNliSE riNNATED BEKBERRIES. 225 XX. — Chinese pinnated Berberries. By Robert Fortune. In tlie earlier volumes of this Journal there are several notes of mine on Chinese plants inti-otiuced by the Horticultural Society from 1843 to 1846. Some of the plants noticed then were almost unknown to cultivators in tliis country, and it was difficult to convince the learned in sucli matters that they were of much importance. Time, however, often does what nothing else can do. After three more years of travel in the far East, I return to find many of my Chinese pets in high favour, and occupying tlie places in our gardens which they so richly merit. It is unnecessary now to write of the beauty of such plants as Dieljjtra spectabilis, Weigela rosea, Forsythia viridissima, Jasminum nudijiorum, Spircea primifolia jjlena, and many others which need not be mentioned. Leaving these to work their own way^ in tlie world, I must now introduce to notice some strangers of no less interest and beauty. Amongst the most striking of these are tiiree species of evergreen pinnated-leaved Berberries, discovered in the north of China. 1. Serberis Bealei. The first was met with in tlie autumn of 1848. I was then travelling in the district of Ilwuycliow, a place famed for its green teas, and which furnishes nearly all tlie finest kinds which are exported to England and America. The discovery is described in my journal as follows : — " Having taken a survey of the place [an old garden], we were on our way out, when an e.xtraordinary^ plant growing in a secluded part of the garden met my eye. When I got near it I found that it was a very fine ever- green Berberis, belonging to the section of Mahonias, and having of course pinnated leaves. Each leaflet was as large as the leaf of our English holly, spiny, and of a fine dark, shining green colour. The shrub was about eight feet high, much branched, and far surpassed in beauty all the other known species of Mahonia." AYhen dried leaves of this plant reached England it was supposed to be identical with Thunberg's Ilex japonica, of which there is a figure in his ' Icones Plantarura Japonicarum,' and which is no doubt a Berberis, and not an Ilex. After a care- ful examination, I have come to the conclusion that the Chinese plant is really distinct from Thunberg's ; and I therefore pro- pose to retain the name of Berberis Becdei, whicli I gave it in the ' Gardeners' Chronicle ' for 1849. I have no doubt that it is quite as hardy as an English holly ; and, if it proves so, it Avill be one of the noblest Evergreen bushes of which our gardens can boast. VO-L. vn. R 226 CHINESE PINNATED BERBERRIES. 2. Berberis consanguifiea. The second species {Berberis consanguinea) was found in the same distiict by one of my Chinese servants. It is easily distin- guished from the former by the colour of its stems and leaves, which are of a light green. The leaflets are also more lanceolate in form, and have a tendency to vary ; that is, some are lanceolate and some ovate or corolate. This is scarcely inferior in beauty to the last, and no doubt quite as hardy. 3. Berberis tr if urea. The third species (^Berberis trifurca, Lindl.) was found in the province of Chekiang, and near the coast. I bought it in a cottage garden, but I was informed afterwards that it is culti- vated extensively on account of the dye which it furnishes. It may be easily known from the other species by its dark green lanceolate leaflets, and, as Dr. Lindley has well observed, by the terminal one, wdiich is almost always sessile. Its young stems are also covered with scales of a clear reddish purple colour, which give it a marked appearance. It is just possible that this species may be less hardy than the former, having been found about two degrees further to the south. This, however, remains to be proved, as it may have been brought south to the province of Chekiang for the purposes of cultivation. There is a marked difference between tiiese three Chinese species and the Himalayan Berberis nepalensis which it may be well to notice. The leaves of the Chinese kinds are of a stout and leathery texture, somewhat like the common holly, while those of the Himalayan species are thin and more flimsy. This difference in structure may be owing to the Himalayan plant courting situations of shelter and shade, and moreover accounts for its being less suited to bear the extreme cold to which the northern Chinese plants are liable. The Chinese Berberries just noticed are all in the nursery of Messrs. Standish and Noble at Bagshot, but they are at present extremely rare and not for sale. They are propagated readily from cuttings ; but although they grow vigorously enough, there is a difficulty in getting any number of young shoots for the pur- poses of propagation. As soon as they produce seeds they may be expected to become plentiful, and will no doubt be highly prized by all lovers of ornamental Evergreens. CULTIVATION OF THE PAULOWNIA IMPEIUALIS. 227 XXI. — Cultivation of tlie PauloiLmia itnperialis. By Charles Dorrien, Esq., F.li.S. As this handsome tree so rarely flowers in England, though it grows vigorously, it may be interesting to some of the Society to learn the circumstances under which it has produced blossoms here, in perhaps rather a favourable situation on the south coast, and not more than 50 or 60 feet above the level of the sea. The plant I possess is now nearly 14 feet high, and the circum- ference of the stem, at a foot from the ground, is 14 inches. For several years it continued growing luxuriantly, making long shoots every summer, which only partially ripened their wood. It was planted in a large slate-box, and plunged in tlie gromid, which was turfed over ; the year before last it was removed, and in the operation it was foinid to have sent down several roots more than an inch thick, through the drainage holes into the soil beneath, which were necessarily cut off; and it was re- planted in the same box in front of the iiouse, in an aspect nearly due south, and sheltered from wind. In 1851 it did not grow so luxuriantly, and the summer having been unusually hot and dry, in fact, there had been no rain for more than two months, the leaves began to look yellow in September, when the shoots of the year began to show blossom-buds in the axils of the leaves, forming a terminal spike of six or eight to each branch. My anticipations of bloom were, however, partially disappointed, as in the course of the winter and spring the buds fell off one by one after sudden changes of weather, till at last only three were left. Those remaining opened in May, and much resembled a Gloxinia in form and colour, with the additional merit of being delightfully sweet scented, something like violets, remaining four or five days in perfection. The tree is again (Sept. 13) forming its flower buds, and therefore as the habit of flowering is induced, it may continue to do so. Being a native of Japan, it must require considerable sun-heat in summer, and it is probably the dampness of our climate which prevents it from flowering, by causing it to produce long succu- lent shoots and leaves instead, particularly when planted in deep rich soil. Mine is in light loam, well drained. It seems not to suffer from frost ; but the frequent and sudden changes of the weather in this part of England (where a frost of a few days is often succeeded by a temperature of 40°, with heavy rains, and afterwards a return of frost) cause the buds to drop off, as those of Camellias do under the same circumstances. 1 think it will be worth while to protect the flower buds by some light covering, such as a cornet of oiled paper, during winter. It may be clearly inferred, that the system required to pro- it 2 228 '^ >iEW KliNU OF GARDEN EDGING. diice its Howers is to check its too rampant growth by root })runing and rather a poor (hy soil ; if this is pursued, i)lantiiig it in a sunny place, not too much exposed to winds which injure its broad spreading foliage, I have no doubt it may l)e brought to tloM'er tolerably freely ; a little care would be well bestoweil upon it, forming as it does such an ornamental large shrub or small tree, and for the sake of its fragrance it ought to be near the house, though I am aware many persons have been disap- pointed with it, as I was for some years. If planted in deep loose soil, or in a shady place, I believe it would never flower in this country. Sennicots, near Chichester, \Zth Sept., 1852. XXII. — A new kind of Garden Edging. By Robert Ilogg. When the Great Exhibition building was being erected, a pa- ragraph appeared in a leading article in the Gardener's Chro- nicle, suggesting that the horticulturists of this country should on that occasion direct their attention to improvements in the implements and appliances of their profession. Among the sub- jects mentioned was "another material that would prove higldy useful, would be a cheap earthen\Aare edging to flower beds and walks ; what we now have is too dear and too ill-made." Feeling at that time the want of a durable edging for my own walks, I set about devising something in the material of " cheap earthenware," and succeeded to my own satisfaction in producing an edging wliich answers every purpose, both for cheapness, du- rability, ornament, and easy application. My first intention was merely to satisfy my own wants ; but many friends who saw my edging, and whose opinions in such matters are worthy of consideration, advised me to have it intro- duced for the general good. With this view I have caused some of the tiles to be sent to the Garden of the Horticultural Society, for the opinion of the Soeiety as to their applicability and usefulness. Their great recommendations are durability and ornament. They are composed of the same clay and are manufactured at the same works as the patent hollow bricks, and from m hat I have seen of them, they appear to become harder on exposure to the weather. Cheapness is another great qualification. They can be supplied in any quantity at 10.y. 6d. per 100, or about \\d. each, each tile being one foot in length. I would also call the attention of the Society to the mode by which they are secured in tlieir position, althoi'nii tliey allow \ NEW KIND OF GARDEN EDGING. 229 the borders to be cultivated close to them, and any extent of the soil disturbed or removed. The shoe which passes under the walk being covered with four inches of gravel, when that be- comes " bound " the tiles are literally immoveable, and no wheel- barrow or roller can displace them. They also afford ample drainage for the walks, and under no pretence whatever do they ever harbour slugs. I have had experience of them for nearly twelve months, and I have found them answer all the purposes an edging is intended to supply, and that too at more than one- half less than dwarf box, and nine-tenths less than many other edgings. I call them " Hogg's Edging Tiles for Garden Walks, &c." 13, Gelston Road, Brompton. Note hy the Vice- Secretary. — This kind of edging appears to possess much merit. It is hard, good-looking, a good colour, cheap, and enables the walks to be relieved easily of water. The accompanying figure represents one of the main tiles seen in perspective. It is 4|^ inches broad, 6|- inches deep, and 12i inches long. Informing curves very short lengths of the same kind are employed. 230 KFFECTS OF PKACH STOCK ON TREES WOKKED UPON IT. XXIII. — On the Effects of the Peach Stock on Trees worked upon it. By Robert Thompson. It was mentioned that the trees of (he Shanghae Peach were worked on the Peach stock. As the buds take readily on this, the proceeding was advisable in the first instance in order to secure the sort. Eut it must be removed to the Almond or Plum stocks ; for in this climate no Peach will thrive long budded on the Peach stock ; the ground, it is presumed, is too cold for it. At all events, the leaves after several years acquire partial tinges of yellow : and this goes on every year increasing, whilst the leaves are annually produced narrower and narrower, till at last the tree becomes useless. Peach trees received by the Society from America were generally on the Peach stock, and they invariably became affected in the same way. George the Fourth Peach was one of the best of them. In a series of warm seasons it extended 35 feet along the wall ; but being on the Peacli stock its foliage became so nari'ow and yellow that it was found necessary to remove the tree. The same variety has now a healthy green foliage on the Plum stock. Tliis disease is doubtless the same as that so prevalent in America, where it is termed the Yellows. It is described by the late Mr. Downing-, who perished, so much regretted, in con- sequence of the burning of the Henry Clay steamer ; but his writings cannot fail still to produce a beneficial influence on Ame- rican horticulture. In his Fruits and Fruit-trees of America, it is stated " that this most serious malady (the Yellows) seems to belong exclusively to this country, and to attack only the Peach tree. Although it has been the greatest enemy of the Peach planter for the last thirty (now thirty-seven) years — rendering the life of the tree uncertain, and frequently spreading over and destroying the orchards of whole districts; still, little is known of its nature, and nothing with certainty of its cause. Many slight observers have confounded it with the effects of the Peach- borer, but all persons who have carefully examined it know tliat the two are totally distinct. Trees may frequently be attacked by both the yellows and the borer, but iiundreds die of the yel- lows when the most minute inspection of the roots and branches can discover no insect or visible cause." Now, Peach trees in America are either grown directly from the stone, or they are budded on Peach-stocks, very rarely on the Plum or Almond. In consequence of the buds taking so readily on the Peach, and growing to form orchard trees with such facility, it is preferred. According to the above-mentioned author, a Peach-stone "planted in the autumn will vegetate in the ensuing spring, grow three or four feet high, and may be budded in August or September. EFFECTS OF PEACH STOCK ON TREES WOliKED UPON IT. 231 Two years from this time, if left undisturbed, it will usually produce a small crop of fruit, and the next season bear abun- dantly, unless the growth is over-luxuriant." He also justly obsei'ves that " healthy Peach-stocks afford the most natural foundation for the growth of standard orchard trees." There can be no question as to that ; but when on this stock whole orchards, some containing from 10,000 to 20,000 trees, become diseased in America, and when in England all on this stock, and on no other, are similarly affected under ordinary circumstances, we must conclude that the soil in both countries is uncongenial to the Peach roots. They are soft, spongy, yellow, more like a pale carrot than the roots of trees we usually see. Most probably the soil is too cold for them. This probability is strengthened by the following instance. It was stated that all trees on the Peach-stock, under ordinary circumstances, Avere sooner or later affected. One of the Sliang- hae trees in the Society's Garden has foliage not tinged with yellow as that of the others are, although it is like them worked on the Peach, and is of the same age, planted at the same time in similar soil, and sharing with the others the same aspect. But its luxuriant foliage exhibits a healthy dark green colour. Nearly opposite to where it is planted there is the fireplace of a room adjoining the fruit-room ; the lower })art of the wall is there heated through to the south side, so that there the latter often exhibits a dry surface, when elsewhere it is wet ; and the ground adjoining has been seen thawed when all not near this heated portion of wall was frozen ; it is, therefore, evident that the roots of this particular tree must have been in a warmer medium than those of its fellows ; and to this different circum- stance, all others being the same, the difference as regards being free from disease may be fairly attributed. These remarks may be the means of preventing the planting of Peach trees worked on the Peach-stock, and consequently the loss of the trees when they ought to be at their best. Excepting in parts of the world where the soil is never too cold, the Peach- stock ought not to be used. It is not the loss of only one planta- tion that has to be considered, for in such countries, as some parts of America, the trees rush up with little pains being taken, and they quickly bear sufficiently to repay that little ; but pre- sently disease makes its appearance, and the whole has to be cut down. The ground having been once cropped with stone-fruit, will not well bear such again without great expense in tending, compared with which that of procuring suitable stocks in the first instance would be inconsiderable. 232 ON THE CULTIVATION OF THE POTATO. XXIV. — Remarks on the Cidtivatio?i of the Potato. By- James Hutchison. (Communicated September 14, 1852.) Since the commencement of the disease in 1846 I have grown the potato in various soils and situations in three different coun- ties, viz. Brecknock, Hereford, and Sussex. That the potato should liave become diseased is not wonderful when the general mode of cultivation in former times is considered. When taken up in the autumn they were generally put into large pits, where they underwent a process of fermentation, which to a certain extent injured the tubers. The usual practice with farmers was to keep their potatoes in such pits till about the beginning of May. By this time they had made shoots about six inches long. Those shoots were pulled off and the potatoes ])lanted. Tlie tuber was thus injured by fermentation, exhausted by growth in the pit, and not planted until a late period of the season. It is true that means were used to accelerate its growth by the force of stinuilating manures ; but, if we may judge from the experience of the last few years, such manures have only hastened the pro- gress of its decay. The method I have adopted is directly the contrary. I keep my potatoes cool and dry in winter. I plant early, so as to give the plant all the advantages which a cold and variable climate can afford. With regard to manure, I have taken a hint from the method which has been so successfully pursued with regard to other exotics which have been acclimatized. I prefer a mo- derately poor soil to one that has been enriched by the addition of strong manures. There is another point worthy of consideration, although farmers seem slow in adopting it. Everything should be done that can by means of draining and deep working to raise the temperature of the land intended for the growth of potatoes. To the intelligent reader this will appear self-evident. But I have met with persons who were prejudiced against both draining and deep working. The opinion which such persons maintain is, that the former won't pay the expense, and the latter they have found to do more harm than good. It must be borne in mind that those operations should be performed with judgment. One man will drain a field at a great expense, and not do it properly after all ; another will do it for half the cost of the former, and finish the work in a very efficient manner. With regard to trenching, it is not necessary to bring a foot or two of exhausted soil or stiff clay to the surface all at once. Let the soil be trenched two spades deep, if not trenched before, and throw the first spading MISCELLANEOUS MEMOPwYNDA. 233 to the far side of the trench, and the second or under spading to the near side, and in this way top and bottom will lie side by side. For the successful cultivation of the potato I am convinced that more depends on the condition of the soil than on the appli- cation of manure. It is not until the land is drained and pul- verised to a certain depth that it has the ability of developing its powers. Moreover it is not until it is placed in this condition tliat free ingress is permitted to the carbonaceous and ammoniacal gases of the atmosphere. No sooner is tlie stagnant water drained off, and the soil opened up, than fertilizing gases flow in. This is one of the many ways by which Providence rewards the industry of man. The cultivation of the potato is very simple. I plant in February or Marcli, according to the state of the weather, in shallow drills, running from north to south, drawing the earth well over them. As the ground becomes solidified by wet wea- ther after planting, I take the first opportunity of dry weather and frosty mornings to fork the ground over between tlie drills. By this process the soil will become in fine condition for earthing up the plants, which should be done in good time. Some allow the ground to become covered with weeds, which exclude the sun's influence ; and in the operation of hoeing many of tlie roots of the potatoes are cut, by which their growth is checked — a circumstance which always increases tlieir liability to disease. It is scarcely necessary to say that the potato should be taken up and stored as soon as it is ripe, more especially if there be any appearance of wet weather. If diseased it should be stored in dry eartli, sand, or similar material. I do not say that the practice I have pointed out is a complete safeguard against all disease ; but whoever follows it may look forward with a great degree of confidence botli to " seed time" and " harvest," and he need not be troubled with tliose imaginary terrors which haunt men who trust to quack preparations for the cure of animal or vegetable debility. XXV. — Miscellaneous Memoranda. By Robert Thompson. In the Great Exhibition in 1851 was to be seen the follow- ing :— " A Circular Earthenware Enclosure and Support, for the Fruit and Foliage of the Strawberry Plant, Mliereby the blos- soms and fruit are pi'otected from the blemishes produced by the ravages of the slug, also free from grit from tlie effects of rain. The material of wliich the pan is manufactured, together 234 MISCELLANEOUS MEMOR.VNUA, with its ONtorior surface, retains a wai'in aiul moist alnios[)Iu ic in tlio noiglibourlmod of the plant thiring tlie eoUlest nii!,lit likely to oeeur in the season of its fruiting-. Thus the Havour of the finest species is improveil, and tiie greatest dimensions of the fruit obtained. The manner of using this pan is to allow the plant to grow freelj- till the first blossom is set for fruit, then gather the stems and foliage together within the compass of the cylindrical part of the Strawberry pan, then arrange the blos- soms to be supported by tlie sloping part. This pan has a fine ornamental appearance, with the advantage of ripening its fiuit a week earlier than any other mode of protection. Invented, and provisionally registered, April 28, 1851, by Thomas Smith, 1, Ilamor Cottages, ITornsey-road, Islington." In the Garden this was tried as directed. It does not appear from the trial that it possesses the advantages supposed. The leaves have to be gathered together and taken through the hollow- stem of the pan. They are there comparatively dark and too much confined. The fruit was not so good as in the adjoining- plants that were freely exposed to light and rain. Some fruit of the Acton Scot Peach wasi thoroughly ripened, August 31, under sashes placed over a glazed trellis, the space under the trellis having been filled up nearly close to it, and paved with tiles. The fruit attained fully the average size of the variety, which is not naturally a large sort. It was Tg inches in circumference; tolerably well coloured, and thoroughly ri- pened, being- equally soft on all sides. The flavour was not however so rich as in those grown against an open wall ; and the period of ripening was a fortnight later than that of the same sort against a wall. But the almost too vigorous growth of the tree under glass would make some difi'erence in this re- spect ; for witii a great flow of sap the fruit does not ripen so early. In former seasons the fruit on the glazed trellis did not ripen thoroughly ; its underside, in two seasons, remained hard whilst the side next the sun was soft. That sucli was not the case in the present season must be attributed to the solar heat being partly reflected by the tiles, partly absorbed and given out to the part of the fruit next to them. It can only be accounted for in tins way, for excepting- the introduction of the tiles, all other circumstances were tiie same as in former years. Since the above was written, additional experience has been gained respecting the effects of glazed trellises in ripening other sorts of Peaches, naturally later than the Acton Scot, such as the Koyal George, Noblesse, and Chancellor. With regard to these MISCELLANEOUS ME.MOKANDA. 235 it will be seen that this mode of growing has given more satis- iactory results. The following note was received from i\Jr. Samuel WooUey, Gardener to Heniy Bellenden Ker, Esq. : — ''Cheshunt, Sept. 14, 1852. " Mr. Ker being from home, I have forwarded you a sample of Peaches grown on tiie protected trellis. Those sent are a fair sample. We have had a very good crop. There are four trees, on which there were above 40 dozen, this being the fourth season since planting, and the fruit is better flavoured than those grown on the wall. The only protection the trees had was a little hay thrown over the glass during the sharp frosts in April." The Peaches were of average size, well coloured, and of very good flavour. They appear to be tlie Royal George and No- blesse. The former averaged 8^ inches in circumference, and the Noblesse 8^ inches. The same sorts had been ripe a week previous on the open wall in the Society's Garden. Oa this some of the Noblesse measured 9 inches in circumference. In tliis garden, one of the trees planted under the protected frame, along with the Acton Scot, was the variety called the Chancellor. It bore some fruit which ripened on the 17th September of the present year. The fruits were not from blossoms situated next the glass, on the front of the branches, for those so situated were killed by the frost in spring ; they were from blossoms near the under sides of the branches, so that when full-sized the Peaches were close to the tile paving. They were compared with the same sort grown against a south wall. The fruit in both situations was about the same size, between 91 and 10 inches in circumference. As regards the time of ripening, those on the trellis were about four or five days earlier, but in point of flavour those ripened against the wall had rather the advantage. From what has been stated, it is evident that Peaches can be very well grown in protecting frames, especially with a tile paving under the trellis for reflecting both heat and light, to a considerable extent ; and that early sorts are retarded, but late kinds are slightly forwarded, comparatively with those matured against walls. The facts which I had to state on a former occasion with reference to the Protecting Frame in the Society's Garden, were at variance with the anticipations of the gentlemen wiio proposed the plan, and also with the results they obtained. Mr. Rivers justly observed that this might be owing to the frame being in a situation more exposed to a current of air than those at Cheshunt. The constant ventilation of the frame was greatly reduced, that 236 GAKDEiVS AND OKANGE GROUNDS OF ST. MICHAEL'S. is to say, a three inch opening was left only along tlic back, and perforated zinc in front ; and this season a tile paving was intro- duced under the trellis, as above stated. These modifications have reconciled tlie discrepancy. It is necessary to remark, that in case of frosty nights when the trees are in blossom, the glass of these frames must be covered, for it has been proved in course of the experiment, tliat the blossoms are more liable to be cut off under the glass than they are against a wall. When frost is apprehended, the opening at the back of the frame could be easily closed ; and straw screens could be made for rolling over the glass at little expense. With regard to economy, the first cost of the protecting frame and that of a wall are nearly equal for the same extent of surface. The protecting frame costs about 8c?. per square foot, or 9/. 1*. 6d. per rod. A wall of the standard thickness, 14 inches, may be built for 10/. per rod ; and a 9-inch brick wall for nearly one- third less, or, say for 71. per rod, allowing for piers ; and if we allow another 1/. per rod for foundations, still this substantial wall is upwards of 1/. per rod cheaper than an equal surface of glazed frame. The latter occupies much ground — it requires a breadth of at least 8 feet ; the wall stands on 14 inches. On the other hand, since it has been proved that Peaches can be grown in these glazed frames with ordinary care, they may be reconmiended where walls cannot be conveniently bvult. In parts of the country, also, where the Peach does not ripen well on the open wall, the protecting frame may be employed with decided advantage, provided additional attention can be be- stowed in covering up in cold nights, and in giving more or less air according to circumstances. XXVI. — 77*6 Gardens and Orange-grounds of St. MicliaeVs in the Azores — its Climate and Peculiarities. By P. Wallace, Chiswick House. (Communicated Sept. 16, 1852.) The position of the group of islands termed Azores, or Western Islands, lying nearly half way between England and America, and near the middle of the North Atlantic Ocean, is no doubt well known to most people. St. Michael's forms one of the principal features of those fertile little specks of the ocean. It may be thought that such an atom of the earth could contain none or few objects of sufficient worth to interest cultivators in GARDENS AND ORANGE GROUNDS OF ST. MICHAEL'S. 2o7 England ; and, indeed, gardening in the Azores, as in its mother country, Portugal, resjai'dless of its fine climate for such occupa- tions, has been wofully neglected, but latterly the spirit of improvement has commenced among the wealthy inhabitants of the Western Islands, and shortly St. Michael's Mill possess gardens which can only be rivalled by those at home. Previous to describing the gardens of St. Michael's, it may be well to state that this island is evidently of comparatively recent sub-marine volcanic formation — symptoms of this are manifested at almost every step by the condition of its surface, which exhibits strong marks of having been formed by the violent agency of fire, by which means, in fact, it is supposed the wliole of the Azores have been at different unknown periods forced up from the sea. St. Mary's Island may perhaps be an exception, yet from its strong resemblance in form and general appearance to the other islands, there can be little doubt tliat it has been forced above the level of the sea by volcanic action — it nowhere, however, bears traces of the effects of fire ; and what is equally singular, St. Mary's is the only island of the Azores that \)vo- duces stiff clay. The effects of these volcanic movements have given rise to appearances on the face of the country of a most picturesque and peculiar nature, which possibly are nowhere better exemplified than in the interesting characteristics of St. Michael's. In the eastern end of the island is a deep, extensive valley, surrounded by liigh mountains, many of them from three to four tliousand feet above the level of the sea : this valley is named by the inhabitants Valle das Furnas.* There dame Nature at the present time still keeps her kettles boiling. Tiie hot springs of the valley are numerous ; the most remarkable is called the " Grand Caldeira," situated in the eastern part, by the side of a rivulet on a small eminence, on which is a basin twenty feet in diameter, where the water boils with prodigious fury, rising at times to the height of three or five feet, and so hot that the inhabitants usually boil their Indian corn in it for food. An egg is boiled hard in the springs in about the same time as it would occupy over a hot fire. A few yards distant from tlie Grand Caldeira is a cave in the side of the bank, in which tlie water boils in a furious manner, throwing out thick, muddy water, and often mud alone, to a distance of five or six feet from its mouth, accompanied by a hideous roaring noise. On throwing a stone into the aperture it redoubles its roaring, as if angry at the insult. In the middle of the rivulet are several places where the water boils up with so intense a heat, that a person cannot dip his finger into it without being scalded. On its banks are .several * Valley of Furnaces. 238 GAPvUENS AND ORANGE GROUNDS OF ST. MICHAEL'S. opening's, out of which the steam rises to a considerable lieighl, and so hot tliat it cannot be approaclied. In this truly wonderful valley are found, within a few yards of each other, hot sulphur- water and cold iron-water running side by side. About twenty yards distant from the Bocca d'Inferno, the name given by the inhabitants to tlie cave I liave just described, gushes from a rock a strong stream of delicious effervescent soda-water, surpassing any I ever drank in England, and requiring no iceing to make it cool. Standing at this part of the valley spectators would be led to suppose that the bellows of a mighty forge were blowing near them, while sulphureous streams issue out so numerously that the neighbouring bushes are covered with pure brimstone, con- densed from the steam. The climate of St. Michael's is remarkably regular, the ther- mometer during the summer months ranging from 76° to 80° and 84° Fahrenheit. A few days in the summer of 1851 it stood at 94° in the shade, but the summer was unusually hot. At this period tlie night temperature ranges from 65° to 70° and 76°. During the winter months the day temperature is from 60° to 70°, often rising with strong sunshine as high as 76°. In the valleys, the night temperature at this season ranges from 50° to 60°. In January, I have sometimes remarked the thermometer at 40°, but these were rare occurrences. I have adopted this form of giving the temperature for the sake of brevity, making it summer from May to October, and winter from November to April. The soil of the island is generally a friable loam, and in the plains of considerable depth, a great quantity being annually carried down by the heavy rains which fall in winter. Yet so fertile is this volcanic soil, that I have seen Indian corn growing where there were only six inches in depth of earth on the rock, and producing excellent crops. Many of the Orange- gardens are formed in places where there is little more than from fifteen to eighteen inches of soil above the shattered mass of rock and rubble, which the volcanoes have thrown together. In some localities a thin coating of black, peaty soil is found, but of so loamy a nature as scarcely to merit the name of peat. The native plants of the Azores are not numerous ; some of them, however, are objects of interest : Myrica faya serves the Azorians in a variety of forms, sucli as sheltering their Orange- gardens, and affording fuel, &c., ivhilst its bark possesses the pro- perty of tanning leather, and for this purpose it is much used by the natives. The sides of tlie mountains least exposed to the sea are covered with several species of Laurus, Myrsine retusa, Lau- rustinus, a native .Juniper and Heath, both of great beauty, assuming nuich diversity of habit, according to soil and situation, GARDENS AKD OEAh'GE GROUNDS OF ST.

Campanula Vidalii is the best I have seen of its genus ; it forms a spreading bush, growing from two to three feet high, and producing masses of cream-coloured flowers. These, with the following Ferns, form the principal features of t lie natise vegetation of St. Micliael's : — Balantiiim culcita, "Woodwardia radicans, several common Aspidiums, Os- munda regalis, Hymenopliyllum Tunbridgense, and Lycopodium denticulatum abound. My object in contributing these observations regarding the gardens and Orange-grounds of St. Michael's is, that I tliink they may prove of service to such of our wealthy aristocracy as may possess villas on the shores of the Mediterranean, pointing out, as I will do, what plants they might successfully introduce to ornament their lawns and pleasure-grounds, and those which best resist the baneful effects of the salt spray, when driven by strong winds from the sea to the shore. The garden of Senhor Jose do Canto, the gentleman with whom I was engaged, contains about sixteen acres, a small portion of which is laid out in the shape of a kitchen garden and orchard, the rest in that of lawns and i)leasure-ground. It was designed by Mr. Mocata, a London architect, and is situated on an incline facing, at about a mile distant from the sea. When I arrived it was partly laid out by Mr. Brown, an English gardener, sent here by the Messrs. Osborn, of the Fulham Nursery. A large architectural conservatory was being erected for such plants as were too tender to withstand the sea breeze ; and other operations were in progress for the completion of a good garden. Senhor Jose do Canto at that time had collected nearlj"^ two thousand different species of trees, shrubs, and plants into his garden ; and it was truly an admirable and beautiful sight to see the leafy natives of almost every clime growing side by side. The Anona and tlie Apple, the Guava and the Green-yage, the Loquat and the Peach, the Poinsettia pulcherrima and the old English Oak, all thrive together in this highly favoured little island. No attempt had been made to arrange the plants sys- tematically, but as is generally the case in private gardens, they were planted in the belts or clumps in such situations as were thought suitable for them. The collection comprises some fine specimens of Paulownia imperialis, two of which are thirty feet high, with clear stems, ten fe^t above the ground (the stems measuring three feet in circumference at the base), and round spreading tops twenty feet in diameter. These two trees are about seven years old from the seed. The singular manner in which the Paulownia annually produces its flowers is worthy of notice. AYhen the summer growth is made flower-spikes are 240 GARDENS AND ORANGE GROUNDS OF ST. MICHAEL'S. formed at the point of every shoot ; and so perfect and full are the buds, that to all appearance they are about to open. They remain in this state until the leaves fall off in December, when they present a very singular aspect. The spikes are regvilar in form, and about six inches in length : the flowers are inclosed in a thick, light brown hairy calyx, which, in any climate where the summer is long enough to allow the Paulownia to ripen its growth, would prove sufficient protection to preserve the embryo bloom during winter. They continue in this condition until the begin- ning of March, when the flowers open a few at a time on the base of the spikes ; and they keep in bloom for the space of a month previous to any leaves being developed. At the end of that period the trees become covered A^th light green foliage, which, added to the pale blue Gloxinia-like flowers, present a most lovely appearance. The leaves of the Paulownia, when fully developed, measure from ten to twelve inches in diameter. It also produces abundance of good seed. The forest and ornamental trees that grew and withstood the salt breeze best, are Araucaria excelsa, Pinus pinaster, Pinea, palustris and Canariensis. Many other Pinuses were introduced, but they scarcely survived a year. Eucalyptuses all succeeded well. E. resinifera has been a long time introduced into the island ; and there are some specimens from seventy to eighty feet high. Casuarina equisetifolia and stricta grow in perfection : of the former some plants are twenty feet high, surpassing in elegance of form any lawn tree I ever saw, with the exception of Araucaria excelsa, Avhich I ought not longer to pass over without particularly describing. Our example of this Araucaria was planted in the most exposed part of the garden, without the shelter of a single tree between it and the ocean, yet after some of the severest storms, and when other plants which usually resisted the salt spray best were slightly injured, I could never discover any blemish on the Araucaria, whilst on the other hand, A. imbricataand Braziliana were damaged by the slightest amount of salt winds. One specimen of A. excelsa, in an orange-garden belonging to Mr. Ivens, a merchant of St. Michael's, and situated very near the sea, has attained the height of fifty feet. Another, in the gartlen of Mr. Dabigny, American consul at Fayal, is still higher, and has produced cones, but owing to the absence of male catkins the cones were barren. I ought to state here, that the^reat taste for gardening which now exists in St. Michael's has originated with the English residents on the island. The late Dr. Nesbit was one of the first who began to introduce new plants into his garden at Nesbit's Pico, a small hill, so named from his country residence being built upon it. Here, at the present time, are some of the finest GARDENS AND ORANGE GROUNDS OF ST. MICHAEL'S, 241 Specimens of Camellias, Arbutuses, Metrosideros, &c., in the island. In this garden is a plant of the Cajeputi tree, Mela- leuca Leucodendron, above thirty feet high. The trunk is enclosed in a thick coating of tliin layers of papyriferous bark. The Portuguese name it the paper-tree, on account of its shaggy bark being easily stripped off and divided into sheets, as it were, of fine paper. The light and airy foliage of the Cajeputi, with its ragged coating, gives it a wild, interesting form, and at the same time a character quite its own. I will now cursorily describe all the large trees that have been introduced, many of which have become already important features, not only on the face of the country, but in supplying wood for building, orange-boxes, and for other pur|X)ses. The greater part of the wood at present used for building is impo/ted from America and Figaro. But within the last ten years planta- tions have sprung up on almost everj' uncultivated side of the mountains, where the soil is unfit for agricultural purposes. Formerly every proprietor in the island planted for himself, but latterly a more liberal feeling has prevailed, and now every piece of ground that will not produce corn or oranges is planted with timber trees. I have already stated that Pinus pinaster is one of the best trees for thoroughly resisting the effects of the salt spray ; it is also one wiiich has become universal throughout the island, and is the principal tree employed in the construction of orange-boxes. We have also Laurus indica, named Viniiatico by the Portuguese, and known in England as Madeira mahogany ; tliere is likewise another Laurus, called Camphora by the natives, but it is quite a distinct species from L. camphora. When or how it was introduced I could never ascertain. This tree grows from sixty to seventy feet high, has intense deep green foliage, possesses a strong camphory scent, and produces abundance of spikes of white, sweet-scented flowers, which are succeeded by seeds resembling an acorn. If this tree would prove hardy in England, it would surpass any of our evergreen trees at present introduced. In a neigiibouring garden stood the parent-tree of all the Camphoras in the island ; it is between sixty and seventy feet high, and sixteen feet in circumference at the base of the trunk, which is quite as knotted and gnarled as that of any of our old Oaks. These two Lau ruses are widely disseminated throughout tiie island ; the former is generally planted in plantations, the latter, at one time, was much employed as shelter for the orange- gardens, but being a gross feeder its use in that way has been greatly diminished. In the garden of Jose do Canto are Oaks, Elms, Beech, VOL. VII. s 242 GABDENS AND ORANGE GROUNDS OF ST. MICHAEL'S. Chesnut, Birch, Limes (Tilia europpea), Alder, Walnut, Nettle- tree (Celtis occidentalis), Liquidambar, Ailanthus, Sumach, Fraxinus lentiscifolia (common Ash would not grow), Acers, Olives, Plane trees, the Ploney Locust tree (growing to a large size, and producing abundance of long seed pods from fifteen to eighteen inches in length), and Salix babylonica and its variety crispa. Contrary to an idea I had always entertained, these willows gi'ow finer and larger, planted in high and very drj^ situations, than I have ever seen them near watersides in England. Taxodiumdistichum, another tree generally supposed to thrive best in damp places, when transplanted to a dry spot grew when other plants moved at the same time died. Some examples of this Taxodium, in the driest part of the garden, grew twenty feet high from seedling plants in five years. The above, together with many other deciduous trees, suc- ceeded well in the island. The greater part of them retain their leaves till near Christmas, and are again early in leaf in the spring. Populus alba might almost be called evergreen, retain- ing its foliage to the end of January, and by the end of February it is again covered with young leaves. P. angulata grows quicker than any otlier tree in the island, plants of it having obtained the height of forty feet in little more than five years, forming a stem proportionately thick. Among rarer deciduous trees wliich flourish here is Melia azedarach (the Bead tree), which is covered with masses of lilac-coloured flowers every spring — occupying the place our Persian Lilac does at home. It is much employed in the decoration of triumphal arches, and is strewn in the streets in wliich religious processions pass on saint-days. Erythrina caffra, Crista-galli, and Corallodendrum, all acquire a large size. E. caff^ra flowered last year for the first time in the Azores ; its flowers closely resemble tliose of E. Corallodendrum, but E. caffra being of a much better haliit, and producing its flowers when in full leaf, is superior to it in beauty. Acacia lophantha and julibrissin, owing to the large size they acquire, must be classed as trees. The Portuguese name the A. julibrissin " the Rainbow Tree," on account of its flowers pos- sessing various hues. In addition to the Coniferous plants already enumerated as being capable of withstanding the sea-breeze, are Juniperuses, Cupressus, Callitris, Thuyas, and Taxus. Most of the species belonging to these genera succeeded well in our garden, and if sometimes slightly injured by a continuation of high winds blowing from the sea, the rapidity with which young shoots and leaves were formed in spring soon obliterated all traces of the injury tliey had received. The Cedar of Lebanon and the Deodar suffer GARDENS ANT) ORANGE GROUNDS OF ST. MICHAEL'S. 243 very much and grow slowly, and the common Larch will scarcely exist in the island. Banksias succeed equally well here as in their native soil and climate ; with the exception of B. palustris, they have been all introduced within tlie last four years, and some are already ten feet high, both blooming and .seeding. Protea cynaroides grows well, while every other species intro- duced died. Some years ago Jose do Canto procured some Pro- teaceous. seeds from the Cape, and was successful in rearing young plants of Leucadendron argenteum, which lie planted in an orange-garden. One plant surpa.ssed anything I ever saw ; it is impossible to convey in writing any coiTect idea of tiic beauty of this .silky and silvery-leaved native of the Cape. The genus Ficus is spread over every garden of extent in the island. F. elastica and australis have been many years intro- duced ; they grow to a large size. Ficus elastica retains tlie same straggling habit it has in our stoves. F. australis is a com- pact, noble tree. F. repens will become the Ivy of St. Michael's, growing over rockwork, and imparting a peculiar charm of light and shade — the old leaves being deep green and tlie young slioots a pale yellow, often tipped with a tinge of red. Magnolias likewise appear to liave found a congenial home in the island ; some specimens of M. grandiflora are forty and fifty feet high, with spreading tops like an oak ; at evening time the air is filled with tiie sweet scent of their flowers, and at noonday their branches form a favourite retreat from tlie heat of the sun. All the newlj^ introduced Magnolias appear to thrive quite as well as M. grandiHora, which has been many years in the island. Few Palm trees have yet been planted, but those which have been tried are thriving well. In the court-yards of many houses in the city of Ponta Delgado are Phcenix dactylifera, the Date. They are tall, noble-looking plants, producing abundance of bloom every season, yet, from some cause I could never satis- factorily find out, they bear no fruit. I will now proceed to notice briefly a few of the floweiing shrubs that are worthy of attention. Camellias have long been favourites with the natives. The inner courts of every convent and monastery contain .some noble specimens ; when newly in- troduced from nurseries in England they suffer a little from the winds, and grow slowly ; but in a few years they become accus- tomed to their new home and flourish luxuriantly. I have mea- sured some Camellias twenty feet high, forming lawn bushes like the Portugal Laurel in England. So great is tlie desire for Camellias, that several of the Portuguese gentlemen have purchased plants of all the named varieties in the English and French nurseries. Metrosideroses, Melaleucas, and Callislemons, all thrive well, and form objects of great beauty, flowering well s 2 244 GARDENS AND ORANGE GROUNDS OF ST. MICHAEL'S. in the open air. Metrosideros speciosa surpasses in brightness of colour when in bloom any of the Rhododendrons. I saw one plant in the garden of an old Jesuit college, fifteen feet high, clothed with spreading branches to the ground, and covered with hundreds of bright scarlet feathery flowers ; in fact, this plant and Poinsettia pvdcherrinia are the brightest coloured plants yet introduced. We have Telopea speciosissima in St. Michael's ; but it has not yet equalled the abovenamed plants in beauty. Any one unaccustomed to see the gorgeous Poinsettia in perfection must be astonished at the effect it produces ; its broad deep green foliage well sustaining the glare of bright scarlet furnished by its noble bracts. Brugmansia suaveolens is another plant of great beauty, producing its delicate white flowers four and five times a year. In many parts of the city of Ponta Delgado it is planted in the court yards, and overhangs the streets, filling the whole air in the evening with its delicious odour, a thing particularly desirable in a Portuguese town.

I must not omit to mention the following climbing and her- baceous plants in order to show how complete the Hortus Michaelensis is, and how much more so it, or any country pos- sessing a similar climate, might be made. Ipomoias and Big- nonias produce their showy flowers at every season of tlie year. B. venustaand I. rubro-caerulea bloom from November to March, growing over a stupendous rock-work side by side, and entwining their branches together. The deep rich orange-coloured flowers GARDENS AND OllANGE GROUNDS OF ST. MICHAEL'S. 245 of the Bignonia contrasted with masses of the delicate blue flowers of the Ipomoea was a sight not easy to be forgotten. Passion flowers, Bugainvillea, Clematises, AVistaria, Honeysuckles, Pergularia, Periploca, Jasmines, Lophospernium, Maurandyas, Dolichos, Phaseolus, all impart a charm when trimly trained against trellised walls or climbing up the sides of rockworlv or dead branches placed in the ground for tiiat purpose. Among herbaceous plants I would point out Hedychiums, Canna^, Alpinia nutans, Strelitzias, Heliconia, Cycas revoluta, Calla Eethiopica, Bletia Tankervillia and hyacinthina, Begonias, Lilies, Amaryllis, Ixias, and Tritonias. Of these the Amaryllis bella- donna is the Daffodil of St. Micliael's ; though not a native of the island, it is so thoroughly spread over it that every road-side is quite gay with it in spring. Most of our herbaceous plants and annuals grow well. Dahlias flower from July till Christmas. The only native fruits of St. Michael's are a Vaccinium and a wild Alpine Strawberry. At the present time, besides Oranges, there are numerous Apples, Pears, Plums, Peaches, Nectarines, Apricots, Figs, Grapes, and Strawberries, wliich all do well under proper treatment ; Goose- berries and Currants will not grow. Of exotic fruits there are three kinds of Guava (Psidlum pyriferum, polycarpon, and Cattleyanum, the two last-named being the best) ; the Custard apple (Anona cherimolia), whose fruit is much liked by some; the Date Plum (Diospyros lotus, Kaki, and Virginicus: the former only has proiluced fruit, which, when first put into the mouth, has an agreeable taste, but it immediately becomes so astringent as to render it unfit to be eaten). Jambosa vulgaris (Rose Apple) produces a quantity of fruit not very desirable. The Pomegranate (Punica granatum) bears freely. All the difterent kinds of Granadilla bear abundance of fruit, which is much esteemed by the Portuguese. The Loquat (Eriobotrya japonica) is only second to the Orange, being noble in appearance, and frequently outri- valling the Orange tree in size, while its branches are laden with delicious rich golden fruit in April and May, when the Oranges are all sent to England. The Loquat is the only fruit of its season, and in the opinion of many it is superior to an Orange. Physalis edulis has become wild ; it is found in every hedge-row, and is much used for preserving. Musa paradisiaca, sapientum, Cavendishii, abound in every part where there is a valley or shelter for them. The fruit is seldom left to riperj on the plants, it being found more convenient to cut them and hang them up in a room, where they are quickly matured by the aid of a little sweet oil put in a small hole cut in the end of the stalk. We had the Lee-chee (Euphoria litchi), Longan, the Akee (Blighia sapida), Manimee tree (M. americana), the Wampee 246 GARDENS AND ORANGE GROUNDS OF ST. MICHAEL'S. (Cookia punctata), tlie Papaw (Carica papaya), tlie Malay Aj)))!*? (Eugenia malacceiisis), aiul several species of Anona growinsi^ in the conservatory without artificial heat, and only waiting for a proper place to be })lanted out in tlie open ground. Euphoria Longana Avas in flower when I left St, Michael's. Melons, water and other kinds, are abundant during the summer and autumn montlis. The manner of cultivating them is as fol- lows : — The ground is deeply trenched in April, after which holes are dug tMo feet deep and eight feet apart, the rows being the same distance ; some rich manure is thrown into the holes and mixed with the soil. In this state they remain for a week or ten days, the manure and soil being stirred up two or three times during this interval. Two or three inches of soil are tiien spread over the mixture, and the seeds sown ; a kind of basin is formed to protect the young plants from strong winds, which often blow in tlie end of April and beginning of May. As the plants grow they are thinned out, and the earth round them is drawn up and pressed firmly about the neck and roots of the plants that remain after thinning. Tliis operation is performed two or three times, after which, with the exception of spreading out the shoots and cleaning, they are left to themselves. The varieties of Melon grown are " legion ;" every one leaving the island on a visit returns with some new kind, wliich is generally sown along with the old sorts. In fact, so numerous are the plots of Melon ground that it would be impossible to prevent intermixture of the sorts taking place. I adopted the English method of stopping the shoots, and was more successful than my neighbours. The Water Melon nuist be allowed to run like a Vegetable Marrow, or no success will attend its cultivation. The heaviest JMelon I produced was A kind of Beechwood, weighing 1 1 lbs. and of delicious flavour ; the heaviest "Water Melon 22 lbs. The latter variety is a uni- versal favourite with the Portuguese, serving as food, at the same time quenching their thirst, and furnishing a wash for their faces. Cucumbers grow successfully treated in the same manner. On arriving at St. Michael's, one of the first things I did was to erect a pine-pit, which I made on tiie same principle as the latest erected at Chatsworth. I adopted the planting-out system, having a lining in the front, and a stone path at the back, for convenience of watering, &c. At this time I had not experienced an Azorean winter ; and perceiving tliat material for making linings was likely to be scarce, as few horses were kept on the establishment, I saw it was quite necessary that some other precaution should be taken to insure bottom heat for my Pines. Neither boilers nor hot water pipes could bo procured in the island ; bricks were not manufac- liired, being prohibited by the Portuguese government. At last GARDENS AND ORANGE GROUNDS OF ST. MICHAEL'S. 247 I thought of the old can-flues. I ordered some clay-pipes to be iiiade, eight inches in diameter, and constructed the hot chamber under the bed, more capacious than I would have done had I had liot water. I did this for fear of the flue overheating, and to prevent the roots from being burnt. The cans were laid down on a slight foundation carefully fitted into each other, and covered with a coating of mortar and red pumice stone. This I found quite effectual, and ^ I would not hesitate to grow first rate Pine Apples on the same plan in England. I dislike the method of filling the space for tlie bottom with bricks, as is sometimes practised : it confines the heat ; however little the obstruction, it is too much in the vicinity of tlie pipes. In INIarch, 1850, I received from the late Mr. Wilmot a batch of good succession Pines. The soil had all been shaken from their roots, and they had been packed without moss or straw in a packing case — a jilan I would always adopt when sending Pines a long journey. They arrived in excellent condition, and were planted in a compost of peat, burnt refuse, and well decayed manure, all roughly mixed up together. My method of treat- ment was much the same as that pursued at Chatsworth ; using, perhaps, more manure water, and keeping my Pines gently grow- ing during winter. From May to October, 1851, 1 cut seventy Pines, averaging 5 pounds weight each ; four smooth Cayennes, weighing respectively 12 lbs., 10 lbs., 9 lbs., and 8 lbs. ; six Trinidads, averaging 8 lbs. each ; six Moscow Queens, one 7 lbs., the others 6 lbs. each ; six Kipley Queens, 5 lbs. and 6 lbs. each ; six Antigua Queens, 6 lbs. each ; and Jamaicas, Envilles, and Montserrats, proportionately heavy. The large Cayenne Pine was sent to Lisbon, to be presented to tlie Queen of Portugal. Pines will exist in a half-starved state in the open ground here, but they produce no fruit. Vegetables can be had at every season. Asparagus is much superior to that at home ; the whole stalk is tender and sweet. Seakale was rather difficult to force. Peas could be had from Christmas till June ; French Beans every month in the year. Walcheren Cauliffower was the only one that did well ; it is a real prize, producing fine heads winter and summer. All kinds of Cabbages succeeded well, and Salads of every description can be grown. The foregoing remarks on the gardens of St. Michael's have principally been confined to that of my employer. Jose do Canto was the first to commence gardening on a large scale in the island. The situation for his garden was badly chosen, being exposed on every side to the sea : yet all the plants I have eimmerated, with many others, ffourish well ; but many tender kinds would have done better in a more sheltered situation. With Jose do Canto began the 248 GARDENS AND ORANGE GROUNDS OF ST. MICHAEL'S. present great taste for gardening. Jealous of the improvements he was making, other proprietors began to follow his example. Senhor Antonio Borges, profiting by the bad effects he had wit- nessed in the garden of Jose do Canto, produced by sea breezes, selected a site for his garden in a valley at the west end of the island, very much resembling the valley I described in the begin- ning of this paper. Many plants succeeded well there that would not grow in our garden, particularly American plants. During my stay at St. Michael's 1 designed and partly laid out two large places for the Barao das Laranjeiras and Senhor Jose Jaconie Correa. The Visconde da Praya employs an English cultivator, Mr, Webster, who is propagating and preparing plants for a gar- den the Visconde has proposed making many years. At present not much has been done. Some years ago Senhor Louriano made an English garden, containing grass, rock work, water, hill and dale, fountains, &c., on little more than half an acre of ground. Shortly after the Barao da Fontabella made a garden at Botelho, four miles from Ponta Delgado, consisting of a series of terraces, a large architectural basin, temples, statues, and fountains. In this establishment is a splendid Magnolia grandiflora, some ar- bours covered with Duranta Plumieri, and a plant of Tristania neriifolia thirty feet high ; also some magnificent Camellias, Mela- leucas, &c. This garden is small and very much crowded, yet very interesting. It is connected with Orange grounds that con- tain some beautiful avenues of Pittosporum undulatum. The Orange gardens of St. Michael's are, however, what form the principal wealth of the island. But for them the country would be one large field of Indian corn. To preserve the Orange- trees from being broken by the high winds when laden with fruit, it is requisite to plant tall quick-growing trees round and across the quintas, the Portuguese name of the Orange grounds. These shelters, composed of Myrica Faya, Camphoras, Pittosporum un- dulata and Tobira, each possessing their own particular green, and scattered over the face of the country with an irregular hand, give a wild and varied charm to the landscape almost indescribable. It is every man's ambition to possess a quinta. They toil early and late, live on Indian corn-bread and water day after day, in order that they may purchase a quinta in which to spend their saint-days and Sundays. Quintas are the emporiums of pic-nics ; the places of retreat of the citizens in summer. Most of them contain a snug cottage ; and the shelters aftbrd plenty of shady walks. These quintas are of as many different forms and sizes as they possess owners. Every proprietor is his own decigner, and a great variety of taste is displayed. On one point, however, they all agree, which is that every quinta must have a high tower and flagstaff, from which flags and pennants wave on every occasion. GARDENS AND ORANGE GROUNDS OF ST. MICHAEL'S. 249 Orange-trees were first introduced to the Azores by the Por- tuguese ; and as the fruit became an article of commerce in Portugal, their extension was encouraged in those islands, in all of wliich they grow. Fayal formerly exported nearly as many Oranges as St. Michael's. About ten or twelve years ago the Orange-trees of Fayal became infested by a species of Coc- cus to such an extent as to render the Oranges worthless. It was found impossible to destroy the pest, and the trees were all cut down. Terceira annually exports from twenty to thirty cargoes of Oranges ; St. Mary's one or two. St. Michael's at present is the great mart for Oranges, but unfortunately there, too, the Coccus has made its appearance, and several quintas have been already destroyed. It is supposed by many that the Orange- trees in St. Michael's grow spontaneously, and produce their fruit without any care. This is a mistake. Before the Orange- trees can be planted, a high wall must be built, and Pittosporum uudulatum planted around and across, to break the force of the winds. P. undulatum is now generally used, growing quicker and possessing a more handsome appearance than the other trees employed for this purpose, A hedge of P. undulatum will grow in five or six years from twenty to thirty feet high. When the walls are built and shelters planted, the ground is trenched, but an attempt is seldom made to level it, the walks following the natural undulations. This done, the Orange-trees are planted at a distance of from twenty-five to thirty feet apart, and the ground sown with Lupins, which are considered by the Portuguese to be a favourite food of Orange-trees. Seven years elapse from plantiug-tirae before the Orange-trees come into full bearing ; during which space the garden is cropped with broad Beans, French Beans, Melons, and Water Melons. The quintas of the poorer proprietors are always cultivated ; the wealthy discon- tinue this practice at the expiration of the above-named period. The Orange-trees are annually primed — thinning out their superfluous branches, so as to allow a free circulation of air, which is required for the proper maturing of the fruit. The trees bloom in March and April, and Oranges are gathered as early as November for the London markets. The Portuguese never eat them before the end of January, at which time they possess their full flavour. Orange grounds vary in size from one to sixty acres, and they are rarely wholly occupied by Orange-trees ; Limes, Citrons, Lemons, Guavas, and other fruit trees are scattered about in them. There are only two kinds of Oranges cultivated in the island, viz., the Portugal and the Mandarin ; many varieties of the former exist, and they are greatly improved by the genial climate of St. Michael's. The Mandarin Orange has not been many years 250 GARDENS AND ORANGE GROUNDS OF ST. MICHAEL'S, in the island, nevertheless there are some trees of it fourteen feet high and nearly as niucli in diameter. This capital little Orange has lately been exported to England, where it realizes a higher price than the common St. Michael's. The largest Orange- tree I measured was thirty feet high, the stem being seven feet in circumference at the base. The produce of the trees is almost incredible ; props are ahvays used to prevent the weight of fruit from breaking down the branches. I was told by Senhor Jacintho Victor Vieyra, a gentleman on whose veracity I could depend, that an orange-tree in the quinta of the Barao das Laranjeiras produced twenty large boxes of oranges, each box containing upwards of a thousand fruit. On telling Senhor Vieyra of the large tree I had measured, he assured me that in the garden of the Barao (who was the father of Orange growers in the island) many larger trees had been cut down, having been destroyed by the coccus, which attacks old trees first. In the Orange grounds of the wealthy a small portion is gene- rally devoted to flower gardening and ornamental shrubs ; some- times surrounding their casinho, or in a remote part of the quinta, sheltered on every side from the winds. It is in these places fine specimens of exotic plants are to be found. In a quinta belonging to the Visconde da Praya, at Roche do Cao, are two plants, DracEena draco and arborea; the former has a clear stem, twenty feet high, with a large spreading top ; the stem was six feet in circumference, and nearly the same in thickness to the top — D. arborea was forty feet high. In another quinta belong- ing to the same nobleman, in the centre of a circular Camellia garden, was the best plant of Pandanusodoratissiraus 1 have seen. Much of the fine eftect that might be expected in a large Orange- garden is destroyed by the quantity of shelters that intersect the gardens, yet they possess delightful walks and avenues of Pitto- sporum, and are, on the whole, very enjoyable. Two hundred ship-loads of Oranges are annually exported from St. Michael's, being nearly two hundred thousand boxes. P.S. — I observe that I have omitted to describe the Caiota, (Sechium edule, or Sicyos edulis.) This interesting and valuable plant was introduced to St. Michael's from Madeira — I believe it to be the Sechium edule of Jamaica. It is perennial, and from October to February bears abundance of its delicious culinary fruit. It is esteemed by the Portuguese beyond their native Cabbage, and that speaks volumes in its favour. The substance of the Caiota is much firmer before and when cooked than tliat of the Vegetable Marrow ; its taste partakes of TWO NEW FOKMS OF TRAINING WALL TREES. 251 the flavour of Asparagus and Cauliflower. In my opinion it is the most delicate vegetable I have ever eaten. So much is it esteemed by the Portuguese, that they think tlie English cannot fail to like it, and are making attempts to export it for the London market, as it will keep in a fresh state a long time. I think it could be easily cultivated in England : growing as it does through the summer months, and producing its fruit at a cold season, it would merely require protecting from tlie frost. Yielding its fruit at a time when vegetables are usually scarce, it would be invaluable to gardeners, and a great addition to the dinner-table. Tlie Caiota attains the weight of two to three pounds, delights in a rich soil, and will grow trailing on the ground in the same manner as the Vegetable Marrow ; but the approved way of cultivating it by the Portuguese is to plant it against, and allow it to run over, a high wall. It will bear pruning to any extent. The fruit of the Caiota has a rugged, roundish form, of a pale yellow colour, and somewiiat resembles the fruit of the Shad- dock ; the pulp is pure white. In tlie list of vegetables that succeed in the island, I ouo-ht to have mentioned Potatoes, Carrots, Parsnips, and Turnips. Pota- toes became diseased at the same time as in England, and the disease still continues, more or less, in certain localities. Potatoes planted in December will produce in Marcii ; the same tubers being kept a sliort time, and again put in the ground, will produce another crop ; and a third crop can be had almost within the year. I have had four crops of French Beans in the same way. XXVII. — Two Neiu Forms in which Wall Trees may he trained.* By none of the methods hitherto employed can trees trained on walls be established in less time tlian from 11 to 21 years according to the kind of tree. Take, for example, a. Peach-tree trained half horizontally against a wall 10 ft. high (H<>-. 1) ; this form is one of the simplest and most easily obtained, and 10 ft. are, upon the whole, the most convenient height for the wall. Let us further suppose that Peach-trees are planted alono- the wall at a distance of 7 yards from each other ; each tree will then cover a surface of 25 square yards. Experience shows that this space is necessary in order that these trees, planted in a * Translated from the French of M. Du Ijreuil. 252 TWO NEW I'OU.MS OF TUAINING WALL XllKKS. TWO NEW FORMS OF TRAINING WALL TREES. 253 soil of average fertility, may produce good fruit and preserve a proper state of health. If the secondary branches be placed at a distance of 2 feet from each other, six of them may be developed on each tree. If an interval of two years between the time of obtaining the first and second stages of secondary branches be allowed, it will take seven years to obtain the whole number of stages, and four years more must elapse before the upper secondary branches can attain their full length ; that is, alto- gether, eleven years. If instead of Peach-trees we take Pear-trees, and train them as above against a similar wall, planted as before in a soil of average fertility, and grafted on Quince stocks, the same space must be allowed between them as was allowed in the case of the Peach-trees ; for Pear-trees ought to cover the same surface to be sufficiently productive. But as the secondary branches should be placed only one foot above each other, they cannot be all obtained in less than thirteen years ; and if to that we add four years for the completion of the growth of the upper branches, we have seventeen years altogetiier. Pretty nearly the same period of time is required by all the other forms of training, and it becomes longer still in the cases of Cherry, Plum, and Apricot trees trained against walls ; for these trees have a greater number of secondary branches, the spaces between which ought not properly to exceed 8 inches, and only one stage can be obtained in a year. It takes, indeed, nearly twenty-four years to get these trees into the form men- tioned. It is true the principal branches of these different trees may be sometimes obtained much more quickly ; for example, by making several stages grow in the same year either by winter pruning, or, which is better, by causing the development of buds by means of summer pruning. But these methods can only be adopted in special cases, and when the trees are more than usually vigorous ; otherwise the growth of the lower secondary branches is almost always injured. What we have stated above is then true as a general rule. But length of time is not the only ground of objection to these forms of training. If by any accident (and this often occurs in stone-fruit trees) one of the secondary, or even one of the primary, branches be lost after the tree is formed, whether it be fan-trained, en canrlelabre, or horizontally with two stems, it is a matter of exceeding difficulty, not to say impossibility, to refill the space thus left empty. The tree consequently, during the remainder of its existence, occupies profitably only a portion of the space originally allotted to it. . On the other hand the different methods at present in vogue, 254 TWO NEW FOKMS OF TRAINING WALL TREES. and especially those of fan-training, ccmdelahre, or horizontal, from double stems, demand no little attention and care in order that the vegetation of the different parts of the tree may be kept in equilibrium. This cannot by any means be done by every gardener, and occupies a very considerable quantity of time. In short, as matters stand, a period of time varying from eleven to twenty-one years, according to the species, is required to make a tree completely cover the space which ought to be allotted to it. A consequence of this is, that about one half of the wall remains unoccupied for five, eight, or ten years, accord- ing to the kind of tree, without reckoning the spaces which are lost during the whole life of a tree by the death of one of its branches. The unprofitableness of one half of tlie wall for nearly eight years, in the case of Pear-trees, is to be regretted, notwith- standing that it bears a small proportion to the whole time during which these trees are profitable, and which, under good management, is about sixty years. But this loss becomes much more important in the case of stone-fruits, such as the Peach, which does not last above twenty years, or as the Apricot, Cherry, and Plum, which cannot be kept profitably more than thirty years. It was to avoid this loss of space and time that formerly the trees were (and even now too often are) planted much closer to each other than we have mentioned, so that each one covered much less space, and was more quickly developed. But this plan is still more disadvantageous than the other ; for the sap, being confined in too small a space, makes the tree so vigorous that it will not fruit at all. We have several times seen Pears on walls thus planted, and which, although some forty years old, had produced nothing but such an abundant supply of wood, that it had to be removed every year. At other times trees are planted close, with the intention that when they interfere with each other every other one shall be removed. But then one does not like to make this sacrifice when the time for it arrives ; or, if it be made, the trees which remain can withdifliculty cover the spaces left vacant, inasmuch as their roots, as they extend, enter ground already ex- hausted by the trees removed. To overcome these inconveniences we were led to train fruit- trees in two forms, which can be established with less difficulty than any other, and which, allowing the trees to cover tlie wall regularly and quickly, do not interfere with their longevity or productiveness. One of these forms is the following : — Simple oblique course (fig. 2). The annexed figure was ori- ginally published in 1846, in the first edition of tlie Author's Cours d' Arboriculture. 'N^^e have no hesitation in again draw- TWO NEW FORMS OF TRAINING WALL TRLES. 255 256 TWO NEW FORMS OF TRAINING WALL TREES. ing attention to the arrangement there shown ; for it is very im- portant, and has been attended witli complete success wherever it has been adopted. The Peach-trees (for this plan is only ap- plicable to them) are planted obliquely at a distance of 34 inches from each other, and so that, the stems being inclined at an angle of 45°, the perpendicular distance between any two of ' them which are adjacent may be 2 feet. At the first pruning the stem is cut at about 20 inches from the graft, and during the following summer the shoots which make their appearance are so managed that an elongation is obtained only at the top, whilst fruit-branches are produced on the two sides. The next year the length of the new growth is left at from 2 feet 4 inches to 3 feet, according to the strength of the tree, and the fruit- branches are treated in the ordinary way. The stem of each tree is thus made to elongate continually, in the line of inclina- tion, until the top of the wall is reached. The tree is then completely formed, and consists of one single stem inclined at an angle of 45°, and bearing nothing but fruit-branches. Fear might be entertained lest the sap, being confined to a single stem, should cause the lateral buds to develope too vigor- "ously to admit of the formation of flower-buds. But this action of the sap being proportional to the quantity of the roots, and these being confined by their proximity to each other, tlie vigour of the trees does not become excessive. Tlie walls against which trees are thus trained should not be less than 10 feet in height, otherwise the trees will, notwithstanding their inclination, be too •confined to fruit well. In order that empty spaces may not be left on the wall, it is necessary, as appears from the figure, to begin the series of trees, to the right, with a half horizontal, and to end, to the left, with a, tree bearing a liorizontal principal branch A, which itself must bear secondary branches inclined at an angle of 45°. This prin- cipal branch is in fact nothing but the original stem of the tree gradually brought down, and upon which the secondary branches have been allowed to develope, beginning with those farthest from the stock. Let us now see whether this arrangement does or not possess the advantages we ascribe to it. And first, inasmuch as the successive elongations of each stem when pruned are on the average 32 inches in length, it cannot take more than 6 years -at most to cover a wall 10 feet in height, since the stems inclined at an angle of 45° are at the end of that time upwards of 16 feet long. Five years, then, at least are gained by the above method, which cannot be gained by any of the others, and most •of the inconveniences attributed to them are at once avoided by this. If one of the trees should die, another may be put in its TWO NEW FORMS OF TEAINIXG WAI.T, TREES. 257 place, and the empty space is soon refilled. Lastly, tliis form of training is very easily accomplished, and the regular inclination of the stems renders the means of equally distributing the action of the sap extremely simple. As to the productiveness and longevity of trees thus trained we are perfectly satisfied, both by those which were planted by us 10 years ago in the Garden of Plants at Kouen, and by otliers since planted in the environs of Paris, and all of which are quite equal to those treated in the ordinary way, that in this respect the above plan is inferior to none. But as we have said, the plan can only be followed in the case of Peach-trees. The following arrangement, wiiich is quite new, appears to us to be ai)plicable and with similar advantages to trees of other sorts. Double oblique Course {Jig. 3). — The only difference between this and the arrangement already described is that in the latter the perpendicular distance between the stems was 2 feet, whilst in this it is only 1 foot. That is the space which ought to sepa- rate the branches of a Pear-tree, which ha.s been taken as an example in the figure. This necessity, however, gives rise to another ; the trees being planted at a distance of nearly 3 feet from each other, in order to attord their roots sufficient room, two branches have to be developed instead of one as before. This sort of training is established as follows. The trees should be strong maiden plants ; they should be planted ver- tically with proper care in the places marked. The fir-^t year nothing more is to be done than to remove portions of the .stem in order to establisi) an equilibrium between it and the roots. The next year a single shoot at the top of each stem must be left to grow vigorously, all the others being converted into spurs by the proper means. In the spring of the following year, the young trees having taken goofi hold of the ground, and already grown, each stem is to be inclined from its base at an angle of 45°. During the succeeding summer one vigorous shoot is al- lowed to develope in a vertical direction inmiediately above the bend. In the 4th spring the branch produced by this bud i.s itself bent, half a yard above the ground, parallel to the first branch. Care is to be taken during the next summer to maintain an equal vigour in the two branches of each tree, and to promote the vigorous growth of each terminal shoot by converting all the others into spurs. In pruning, about 32 inches of the leading shoots should be left, unless they are of unequal strength, in which case the strongest is cut shorter. The same operation is repeated eveiy year until the trees reach the top of the wall. If it were desirerl to apply this plan to Cherry, Plum, or Apri- VOL. VII. T 25.8 TWO NEW FORMS OF TBAINING WALL TKEES. to TWO NKW FOKMS OF TEAUNING WALL TUBES. 259 cot trees, the young trees should be planted at a distance of 2 feet instead of nearly 3 feet from each other, in order to have the branches 8 inches apart, which is sufficient in these cases. The advantages of this plan are the same as those which belong to that adopted in the case of Peach-trees. The two branches which each tree has may be obtained in 6 years at most, and thus time is gained to the extent of 11 years for Pears and lo years for Cherries, Plums, and Aprii-ots. The powers of pro- duction and of vitality do not appear to be lessened by adopting the double any more than by adopting the single course. It is no small recommendation to be able to adopt, for trees against walls, a form which is obtained and kept up at a much less cost of time and care than is ordinarily incurred, and to fill up with ease any empty space to which acciilent may give rise ; but if in addition we find that the same surface of wall is covered by the plans proposed in one half the time taken by those ordi- narily followed, the advantages appear to us to preponderate greatly in favour of the former. It cannot be denied that the new forms are less agreeable to the eye than most of tlie others, but that will not be thought of much moment by those whose object it is to derive profit from their trees. — Revue Horticole, Sept. 1852. XXVIII. — New Esculent Vegetables and Fruits examined in 1852 in the Society^ s Garden. By R. Thompson. " Hardy's Transmuted Shallot to Onio7i" or Hardy''s Shallot Onion. Seeds of this were presented to the Society, March 20th, 1851, by INIessrs. Hardy and Sons, Maldon, Essex, ac- companied with the follow iug note : — " The transmuted shallots, or rather onions, raised by us from shallot seed, and planted last winter, did not produce potato onions, as was presumed they might, but numerous heads of seed varying from 10 to 20 from a single bulb. They certainly pos- sess the qualities of both onions and shallots in flavour, size of the onions, and the fact of their being divisible like shallots. The blade is very narrow, partaking of both species. The seed is small." The seeds were sown when received, March 20th ; and the produce is a mixed race, varying in size, form, and colour. Some are regularly formed by concentric layers, like an onion, and not unlike a Reading onion. Sometimes the formation con- sists of two closely-conjoined, compressed, but separable bulbs ; T 2 260 NEW ESCULENT VEGETABLES AND FRUITS and frequently clusters are produced very like shallots. Tlie colour in some approaches that of the Silver-skin Onion, in others the Blood-red; but tlie generality are reddish-hrown. They are strong-flavoured, and have tlie appearance of being- good keepers. From the want of uniformity in the size and form of the bidbs, the crop would not be profitable for the growers for market. By a judicious selection of bulbs for seed a useful sound-keeping variety may very probably be obtained. Florentiner PJlucherhse Pea. Presented to the Society by Mr. Seitze, Royal Gardens, Munich. This was stated to be a good variety of early pea. It proves the same as the Early Frame. Paradise Pea. Presented by Messrs. Stuart and INIein. Sown May ITth ; fit for use July 23rd. About 4 feet higli ; pods straight, flattish, containing 6-7 peas of good quality. An abundant bearer. Dry seeds yellowish-white. Allied to the Early Charlton. Dorii de Fitz-James Pea. Presented by Bossin, Louesse & Co., Paris. Sown May 17th; fit for use July 20th; about 4 feet high; pods straiglit ; flattish, in shape and size like those of the Charl- ton, but the pods, and also the peas, are pale yellow. It is a curious degeneration, most probably from the Charlton ; the plants are similar in growth to those of the Charlton. The quality of the peas is very good ; but the want of greeiniess in the pods, even in a young state, would render the sort not mar- ketable. SuttOH'S Early GoliatJi Pea. Received from Messrs. Sutton and Son. Sown May 17th; fit July 18th; about 4 feet high. Pods tolerably large, containing about 7 gooil-sized white peas, of ex- cellent quality. A very good early productive pea. Sutton^s Superb Marrmofat. Received from Messrs. Sutton and Sons. Appears to be the same as the Woodford Green Marrow. EXAMINED IN THE SOCIETY'S GARDEN. 261 Early Prince of Wales Pea. Presented by Messrs. Whalley of Liverpool. Sown February 16th; fit June 2oth, Appears to be a well- selected Early Frame. Royal Alfred Pea. Presented by Messrs. Weeks and Co. Sown February 16tli; fit July 14th ; from 3 to 4 feet high, of strong growth ; pods large, nearly straight, containing 6-7 peas of good quality. A sort of Marrow, but not so sugary as Knight's. Trial of Early Peas. — The following are the results of sow- ings of different kinds of Early Peas, made with the view of ascertaining their comparative merits in point of earliness : — 1. Earhj Frame 2. Earh/ Kent . 3. Early Emperor 4. Sanyster's No. 1 . . 5. Earl;/ Charlton 6. Early Long-podded Bishop's Dwarf 7. Early Surprise The first four of the above may be considered identical. Sang- ster's No. 1 was admitted to have been sent out in mistake. Slight differences will take place in the Early Frame, and other sorts, in consequence of the mode of saving. Hence the Early Kent and Early Emperor ; but they are certainly not decidedly different permanently. They were exactly alike in the above trial. Haricot de Prague jaspe. Obtained from M. Vilmorin, of Paris. This is a tall running Kidney Bean, but the pods are rather thin-sided, and the seeds soon become prominent, therefore it is not to be recommended for use in a green state : the dry seeds, however, are said to be of excellent quality. Haricot de Belgic. Presented to the Society by Messrs. Bossin, Louesse and Co., Paris.

A tole- rably good bearer, but not very early. AVhere sticks can be afforded, this variety deserves cultivation, for its quality is veiy good. Bush Haricot {Haricot solitaire). Obtained from M. Vilmorin, of Paris. Seeds of this were distributed to the Fellows of the Society. Grows about 15 inches high, throwing out a number of branches nearly close to tlie ground, thus forming a sort of bush. The slioots successively emitted bear in succession ; whilst they also shade the ground, and tend to keep it moist in dry weather. The flowers are of a pale blush. The pods are abundant, 5 inches in length, crisp, transparent, excellent. They commence to form tolerably early, and they continue long fit for gathering in succession. The dry seeds are speckled red and white. The rows siiould be 2 feet apart, and the plants half that dis- tance from each otlier in the row. This forms a valuable succession to the earlier sorts, especially during hot, dry weather. Small white-seeded Haricot. Presented by Jolm Tinne, Esq. This appears to be a variety of the Haricot viz. The seeds are small, white, roundish-oval, like tliose of the Haricot riz, but larger; and the plant is earlier, more productive, and hardier, con- sequently better adapted for this climate. Its growth is between dwarf and tall. The blossoms are white ; pods long, rather narrow, pale green, tender, but not so fleshy nor so good as various others for use in a green state. It may, liowever, be well substituted for the Haricot riz in cases whei'e that variety is preferred on account of its small white seeds. Newington Wonder French Bean. Seeds of this were received from Messrs. Lee, and from Mr. Rendle. Both proved to be correctly the same variety ; and it is an excellent one. Very dwarf, about a foot high, early, and pro- ductive. The pods are moderately long, not very broad, but having tliick fleshy sides, within which the seeds form but slowly, and the pods remain long crisp ; their colour is dark green. It may be planted in rows 18 inches apart. EXAMINED IX THE SOCIETY'S GAKDEN. 263 Black Belgian Kidney Bean. Received from M. Vilmorin, of Paris. Although this variety has been previously noticed in the Society's Journal, yet the present mention of it will doubtless be excused, for it may be usefully stated that it is the best for botli early and late sowing-. It is dwarf, and may be sown in pots before tlie open ground has acquired sufficient warmth, and if planted out when this is the case it soon comes into bearing. Again, late in summer, when taller sorts would not even blossom if tlien sown, tlie sort in question will produce a good crop, that will keep in gathering condition till cut off by frost. This, and tlie Newington Wonder, are considered the best varieties of dwarf Kidney Beans. Tilrkische Bohne (^Schlachtschwerdt-Stangenbohne). Presented to the Society by John Tinne, Esq., together with the original label, bearing the above name, under which he had obtained the variety from the Continent. It was also stated on the label that {^^ diese Sbrte liefer t 12 bis 14 ZoU lange und ubei- 1 Zoll breite Schoten''^) this sort bears pods from 12 to 14 inches in length, and upwards of an inch in breadth. They did not attain these dimensions here, the season being dry, and the ground cold in the early part of summer ; but some were ten inches long, and nearly an inch broad, and doubtless they would grow to the full size mentioned in a moist warm season. It appears to be the same as the Haricot Sabre d' Allemagne of Noisette's Manuel du Jardinier^ and the Sabre of the Bon Jardinier. It grows tall. The pods are large, curved, tender even when the seeds are half grown, but the latter then render it objec- tionable. It does not remain so long in gathering fit for use in a green state as the Bush Haricot {Haricot solitaire) and several others, nor does it bear so abundantly. It has, however, good qualifications, which are thus described in the Bon Jardinier : — " This vai'iety is, perhaps, the best of all ; it bears tolerably well ; its pods are of an extraordinary length and breadth ; in a young state they make excellent haricots verts; when nearly full-sized they are still tender and fleshy, and may be used in this state, either fresh, being broken in small pieces, or, in winter, after being cut into narrow strips and preserved with salt." The diy seeds are tolerably large, flat, kidney -shaped, and white ; and in point of quality the French rank them amongst the best, whether used new or dried. It therefore appears that this variety possesses good properties, which those 264 NKW KSCULliNT VKUETAHLES AND l-TvUIT;* who can may fiirii to account. But it is iieccssiry to observe that it requires good tall sticks, and these are too expensive, excepting- for those who have their own plantations to cut from. Duchessc de Trccise iSlraivherri/. Presented to the Society by M. Janiin, liourg-la-Reine, near Paris, Sept. 6, 1851. Fruit middle-sized, ovate, tleep red ; seeds small, rather deeply embedded ; flesh pale red, juicy, with a brisk rich Ha\ our. Leaves large, roundish, widely and ratlier obtusely serrated. Leaf- stalks moderately tall, very hairy, the hairs on these spreading horizontally, but those on the scapes and runners are adpressed. Appears to be a good bearer, ripening quite as early as Keens' .Seedling. It will require to be planted as widely apart as the sort just mentioned. As far as can be judged of it in the present season it seems deserving of cultivation, or, at all events, cer- tainly of further trial. Salter s Versaillaiae Strawberry. Presented to the Society by Mr. .John Salter, Nurseryman, Hammersmith, Oct. 24, 18.52. Fruit large ovate, sometimes flattened or cockscomb-shaped ; dark red ; seeds rather deeply embedded ; flesh pale, juicy and rich. Leaves middle-sized, roinidish-oval, widely serrated. Leaf- stalks, scapes and runners hairy, the hairs spreading almost hori- zontally. A good bearer, ripening about the same time as Keens' Seedling, to which it will doubtless be preferred by those who like a brisker flavour than is possessed by Keens' Seed- ling. On the whole, it is worthy of recommendation, being large and a good bearer ; many of tlie new sorts have these pro- perties only, but this has also good flavour. BeadnelVs Seedling Pear. This was raised by John Beadnell, Esq., West Green Roatl, Tottenham, and cuttings of it were presented by him to the Society. The fruit is nearly middle-sized, turbinate, stalk short; eye a little open ; skin pale yellowish-green on the shaded side, red next the sun, much speckled with whitish-grey dots. Flesh melting, exceedingly juicy, and ricii. It is not buttery, but so melting, when used in its full })erfection, that one can scarcely say whether he is not rather drinking than eating. Its period of ripening varies between the nuddle of September and that of KXA.MINED IN THE SOCIETY'S GARDEN. 26o October. It does not keep lon;^ after being ripe. The tree is vigorous, and bears very abundantly. Slioots long, bright chestnut coloured where well exposed, much spotted with whitish dots. Leaves moderately large, cordate on the young shoots, somewljat concave and acuminate, serrated ; those on the spurs are elliptic. Stipules linear, rather more than half the length of the petioles. This variety cannot fail to be very acceptable on account of its rich, abundant, and highly refreshing juice. Shanghae Peach. This variety was sent to the Society by Mr. Fortune, who found it growing to a very large size in the North of China. Along with a plant of it in a pot, he sent some of the peach stones. These were sown and came up abundantly ; but they had a very unpromising appearance for fruit, tlieir foliage being narrow, and altogether unlike that of a cultivated sort. They were, however, potted, and when fit, used as stocks for the origi- nal. Several trees on these stocks were planted against a south wall, where they grew rapidly. The trees have produced better fruit this year tlian formerly, probably owing to unusually high temperature in July. The flowers are large ; the leaves of the petals deeply coloured. Leaves crenated, with reniform glands. Fruit very large, 10 inciies or more in circumference, roundish, and very handsome ; pale yellow where shaded, and delicate crimson red next the sun. The flesh is pale yellow next the skin, but very deep red at the stone, to which it is attached by strong fibres, yet it is not every- where adherent like the flesh of the cling-stone peaches. It is juicy and rich, but it recpiires to be gathered a day or two before it is used. In tiiis state some gentlemen preferred it to old esteemed sorts. It ripens about the same time as the Bellegarde. The tree is a good bearer. Buds of this sort have been distributed to the various nursery- men or other Fellows of the Society who applied for them. It nuist however be observed, that it requires a good aspect, and warm situation. It would probably answer for forcing, with plenty of heat. Some buds of it were sent to Paris, and there its fruit is said to be splendid. Like all large fruited varieties it ought to be well thinned. ( 266 ) i/ NEW PLANTS, ETC , FROM THE SOCIETY'S GARDEN. 1. Sedum ruRPUREUM. Link, Enum. Hort. Berol., I. 437. Ledebour, Fl. Rossica, II. 181. Received from J. Gent, Esq., in April, 1852, under the name of Sedum purpurascens. By many writers this is regarded as a mere variety of Sedum Telephium, and their opinion is probably correct. It only differs in being pervaded by a very deep purple tint, and in the leaves being wedge-shaped and narrow at the base, instead of being oblong and rounded at the base. The petals also are flat, not channelled at the point, and the stamens are rather longer than the petals. It grows naturally in middle Russia, and all over Siberia, whether in the Altai, the Ural, or the Baical, reaching even to Kamtchatka, In cultivation it is a hardy plant, growing 18 inches in height in any good light rich soil. It is increased by dividing the old plant in the ordinary way. It flowers in August. It is a rather sliowy and desirable plant for rock-work in summer. 2. Pelargonium foliolosum. De Cand., Prodr., I. 653. Geranium finnatum. Andrews, Bot. Repos., t. 311. Purchased from Mr. "Wicks, a collector of Cape plants, May 3rd, 1852, as a Yellow Pelargonium. This is one of tlie fleshy-rooted species, often called Hoareas. It has hairy pinnated leaves, with about 7 pairs of ovate entire leaflets, and an odd one, which is much broader and rounder. The flower stem grows higher than the leaves, and divides into two unequal arms about the middle ; of these, one flowers some weeks before the other. The umbels consist of 6 or 8 blossoms, with hairy stalks 3 times as long as the subulate bracts. The petals are linear, channelled, recurved, blunt, pale clear buff, tlie two upper standing nearer to each other, and with a deep crimson spot in tlie middle. Tliis was obtained for the sake of its yellow flowers, which it is hoped may be made to change the colour of some of the large- flowered Pelargoniums. As the pollen is good, this may happen. NEW PLANTS, ETC., FROM THE SOCIETY'S GARDEN, 267 It is a tuberous plant, requiring- a good rich sandy soil, and to be treated like the ordinary kinds of Pelargoniums ; but it must be kept rather dry in winter. As has been stated, its value will be as a breeder; the flowers are too insignificant to render it of importance otherwise in a gardening point of view. 3. Vanda longifolia. Lindley's Genera and Species of Orchidaceous Plants, p. 215. Presented to the Society by the Honourable Court of Directors of the East India Company in 1847. Flowered Sept. 3, 1852. This is a very fine looking plant when not in flower, with deep green distichous leathery wavy leaves, as much as a foot and a half long and 2 inches wide, obliquely rounded at the end. Its habit is almost that of Angraecum eburneum. Very thick greyish-green roots protrude from its stem, and have a tendency to branch wherever the first point is injured. But the flowers are insignificant, very much like those of Vanda multiflora in form and colour, except that they are paler ; they, however, have a pleasant perfume. These flowers appear in a corymb at the end of a short stift" ascending peduncle not one quarter the length of the leaves ; they are very fleshy, and are banded with red upon a dull yellow ground ; the lip is white. Inside the pouch of the lip are numerous yellowish hairs, concealing an erect fleshy plate, which partially divides the hollow of the lip into two halves. It is not worth cultivating for the flowers, but the foliage is very fine, and serves to set off" other Orchids. 4. Astragalus ponticus. Pallas, Astragalogia, p. 14, t. 11. Raised from seeds received from H. C Calvert, Esq., of Erzeroom, March 26th, 1850. A decumbent perennial of a bright lively green colour. Stems about 2 feet long, slightly downy. Leaves almost smooth, of the texture of the Garden Pea, about a foot long, composed of 17 or 18 pairs of ovate-oblong, obtuse, or emarginate leaflets. The flowers are bright yellow, in nearly sessile ovate heads, with short calyx tube, much less hairy than in the allied species. The cultivators of hardy herbaceous plants will understand what tliis is when it is compared with Astragalus alopecuroides, which it is a good deal like. It is a hai'dy, half-shrubby plant, growing freely in peat-soil, 268 NEW PLANTS, ETC., and flowerinpf in August. Though not showy, its fine foliage renders it well adapted for shrubberies, coarse rockwork, and flower borders, devoted to the cultivation of the rougher kind of perennials. 5. TiLLANBsiA STRicTA. Botunical Magazine, t, 1529. Received from Miss Croker, of Chiswick, February 23rd, 1852, said to be from Rio. This is a small Pine Apple-like plant, about 6 inches high when in flower. The leaves are very narrow, channelled, mealy, stiff, terminating in a long drawn-out point, and curved back- wards till their ends are below the base of the plant. The flowering stems are shorter than the leaves, curved downwards, clothed with small green leaves resembling those below them. The flowers are collected into oblong cones, formed of shining, naked, roundish ovate, convex, imbricated bracts, the lower of which have a leafy point. Two varieties were observed, one with bright rose-coloured bracts and blue flowers, the other with greenish bracts and white flowers. Among the less important inhabitants of the stove this may be regarded as a useful little plant, growing best in a warm moist air, attached to a block of wood, where it flowers in August. 6. EcHEVERiA QuiTENsis* — Sedum quitense. Humboldt, Bonpland, and Kunth, Nov. Gen. and Sp., pi. 6, 46. Received from Isaac Anderson, Esq., of Edinburgh, in August, 1851. A bright green smooth succulent plant, forming stiff" erect stems about 6 inches high, clothed by imbricated spathulate leaves, with an almost circular base attached to the stem only by one bundle of fibro-vascular tissue. The flowers are in stiff close erect racemes, shorter than the lower bracts, which resemble in form the leaves, but taper less to the base. Sepals 5, longer than the pedicel, equal, linear, acuminate, rather shorter than the corolla, which forms a scarlet five-sided pyramid, opening very slightly at the end into 5 acuminate lobes. Of the 10 stamens, 5 stand in furrows of the petals, and 5 are distinct. This is evidently an Echeveria, as De Candolle surmised, and not a Sedum. During the summer it does very well on rockwork out of doors, but it is probable that it should be treated * E. quitensis; omnibus partibus nuda, caulibus imbi-icatim foliosis, foliis spathulatis apiculatis, sepalis lincaribus aciitissimis aiqualibus suberectis corolla subclavisJi brcvioribus. — J.

It is easily increased by cuttings, and seeds, which it ripens abundantly. When grown out of doors, though pretty, it is not a very striking plant. It flowers in August. How it will look in a greenhouse is not ascertained as yet. 7. Gaura Lindheimeri. Engelmann, in Boston Journal of Natural History, Vol. V. p. 217. Vilmorin, in Revue Horticole, 3. ser. V. 41. t. 5. Raised from seeds received from M. Vilmorin in April, 1850. A branching herbaceous plant, growing from 3 to 4 feet high, and producing an abundance of gay white and reddish flowers during all the latter part of the year. The branches are long, rod- like, naked except at the extremities where the flowers grow. The lower leaves are deeply divided in a pinnatifid or sinuate manner ; the upper are lanceolate and slightly toothed, the upper- most of all are linear-lanceolate and entire. The flowers appear in long virgate spikes, which frequently branch near the end. The petals are pure white ; the flower-buds are long and slender, green when young, a warm reddish brown just before expansion. The seed-vessels are small sessile four-cornered nuts. A perennial, growing freely in any good garden soil, and flowering from July to September. It is easily increased from seeds, and is best treated as a half-hardy biennial. It will not flower before the second season. Having been found in Texas or provinces more to the southward, it cannot be regarded as per- fectly hardy. It is really a showy although a straggling plant, and well suited for decorating mixed beds of flowers, or the skirts of a plantation in the autumn. 8. Oncidium tenue. Lindley, supra, vol. iii. p. 76. Var. grandifiorum. Received from G. U. Skinner, Esq., in April, 1849, from Guatemala. This has so very much the structure of Oncidium tenue that it can only be regarded as a variety ; but it is one of greater beauty than the original. The panicle is much more branched ; the flowers are larger, paler, with two distinct triangular spots at the base of the lip instead of broken blotches. The wings of the column are, moreover, strongly toothed, and the base of the lip is wider.

Raised from seeds received from the administration of the Jardin des Plantcs of Paris through J. B. Pentland, Esq., on 17th of October, 1848. Leaves oblong, obtuse, pale dull green, tapering gradually into the petiole, which is red, as well as the midrib itself; at the back of tlie leaf, in the axil of each principal vein, is a small exca- vation closed up by hairs. The stipules, which fall off very- early, are a pair of oblong, erect, blunt, smooth plates. Tiie flowers appear in panicles at the ends of tlie lateral shoots, are of a pale pink colour before expansion, almost white when fully open, and emit a most agreeable weak balsamic fragrance. The calyx is a small superior 5-toothed cup, covered with fine close down like the branches of the panicle. Tlie corolla has a cylin- drical tube about V inch long, and a reHexed 5-lobed limb, copi- ously fringed with long transparent club-shaped liairs. Tlie stamens are 5, and can just be seen when looking down into the tube of the corolla. Dr. Weddell, in his Natural History of tlie Quinquinas, gives a very full account of this important plant, from whicli the following are extracts : — " From this species is obtained the most precious of the Je- suit's barks used in medicine, employed from time immemorial in trade under the name of Calisaya bark, but whose origin was wholly unknown till now." " I have already observed that this tree has hitherto been only found in Pern, in the southern part of the province of Ca- rabay^a. The results at which 1 have arrived in endeavouring to determine exactly the limits of the region it occupies seem curious enough to be noted in this place. Thus, after having studied the plant in all the ancient province of Yungas in La Paz, to the north of 17° S. lat., I followed it into that of Lare- FROM THK SOCIKTY'S GARDEN. 273 caja or Snrata, tiience into Caupolican or Apolobaniba. the place of its first discovery; and all my care has failed in enabling- nie to find it north of those points. An imaginary barrier exists then beyond which the plant will not go, notwithstanding that the neighbouring valleys appeai'ed to be of the very same nature ; a fact that can scarcely be explained, unless upon the supposi- tion that peculiarities do exist in the most southern valleys of Carabaya which are wanting in tlie north ; and this may pos- sibly be owing to the manner in which the rivers are distributed. I believe, in fact, that I am justified in referring those of tlie district in question to a particular system, possibly dependent upon the Bolivian system, and that those in the other parts of the province lose themselves on the contrary by tlie N. of Peru, in the Upper Amazon. This unexplained attachment whicli certain plants manifest for natural regions, and especially ft)r valleys, is by no means without example; and now that Geo- graphical Botany is obtaining serious attention, science will be enriched more and more with analogous facts." "The great reputation of the Quinquina Calisaya has caused such a demand for it, that it will certainly some day disappear completely from commerce, and we shall be obliged to be con- tent with other sorts now despised. It has already disappeared around inhabited places, except in the form of a bush ; and if by mere chance a small tree has remained unobserved in the midst of a forest, its head no sooner becomes visible tlian the hatchet brings it down. For rny own part, when 1 have wished to see the species in all its vigour, it has been necessary to pass long days on foot in the forests, to penetrate them by paths whicli were scarcely passable, and to undergo some of the fatigues which are the ordinary lot of the poor Cascarilleros." '' Some idea may be formed of tlie inunense consumption of the bark of this plant, from the fact that the Boli\ian Company exports annually, exclusive of adulteration, more than 4000 quintals. It is difficult for the forests to supply for any long time so large a demand." Its native station was found by this enterprising traveller to be on the slopes and precipices of mountains as high as 4500 or 5400 feet in the hottest valleys of Bolivia and Southern Peru, in forests between 13' and 16° 30' S. lat., and 68°— 72° W. long., in the Bolivian provinces of Enquisivi, Yungas, Larecaja, and Caupolican, and in Carabaya in Peru. This plant has been found to require very peculiar manage- ment. Mr. George Gordon, under whose care it flowered in the Society's Garden, states the following to be the manner in which the specimen was treated which bloomed so abundantly in the Society's stove : — VOI>. VII. u 274 NIAV l'I,\NTS, KTC, The seeds, when received from INfr. Pentland in the middle of October, 1848, were sown in shallow pans, well drained, in a mixture of equal parts of sandy loam and fibry peat, and placed in a close warm pit, remaining- for ten days without receiving- any water after sowing. Afterwards they were slightly sprinkled as the soil became dry on the surface, and at the end of about three months of such treatment the young plants began to make their appearance, in the latter part of January. When the seedlings had made a couple of rough leaves they were carefully removed, and placed singly in three-inch pots (small sixtys), potting them in a mixture composed of equal parts of sandy loam, fibry peat, and well decayed leaf movdd, and after a copious watering were returned to the close pit, where they soon began to grow freely. Wlien the young plants were well established a moderate portion of air was given over head, by pushing down the light a little at the top ; and this treatment was continued until the latter part of the following autunni, when the plants were removed to a close pit with rather a drier atmosphere, more light, and a temperature from 50° to 55° by night. Subsequently the plants were shifted as they required it into larger pots, using the same kind of compost as before. As the specimens grew up they showed little tendency to form lateral branches, but became straight stemmed with hardly a side shoot. To counteract this as much as possible, I endeavoured to cause the plants to become bushy, first by pinching off the leading points of two plants while in a very young state ; but that operation threw the plants into a bad state of health, and one of them eventually died. The other plants Avere allowed to grow for another season, and when the wood became hard or ripe, two more had their leading points removed, but with little better success. The remainder had at the same time their leading points tied down in a circular form, which in most cases caused the plant to throw out lateral branches. AVhen the wood of these laterals again became firm, or what is termed about three-parts ripe, they were again tied down and allowed to remain so until the wood became set in a curved form, after which t!ie ties were removed and the plant allowed its full motion, for I found if the branches were kept con- stantly tied down the plants became unhealthy, and in some cases even perished. By a continuation of this treatment I obtained the fine plant \\hich flowered in the Society's Garden, having twelve panicles of flowers on the points of the lateral branches by the first week in September, 1852. In cultivation I find this plant is easily injured by exposure to dry or cold draughts of air, for it is very impatient of direct cur- rents and bright sunshine. For the Calisaya, as for many other plants which are diflftcult to manage in cultivation, nothing is FROM THE SOCIETY'S GARDEN. 27o better than plunging their pots in a very gentle bottom heat to keep the roots moist and warm, and in an equal temperature, and to give air from overhead, shading also during bright sunshine. No method of giving air or putting the air in motion surpasses that of opening the lights above the plants at top, for no sooner is the light let down than the stream of heated air which rushes out is forcibly met by the cold air endeavouring to enter, the result of which is a proper medium of heat and moisture. It is very injurious to such plants as the Cinchona Calisaya to admit direct currents of cold air on a level with or below the plants. It is sure to rob the atmosphere of its moisture first and the f)lant afterwards, and by so doing causes the plant to flag ; no plant, indeed, can thrive when acted upon in such a manner either by cold or dry air. This is one of the principal things to be observed in the management of the " Calisaya." A moderate degree of heat and moisture are essential points, provided the moisture never becomes stagnant or the air over dry by heat, especially when the plants are making fresh growth and the leaves are young and tender. At other times when the plants have completed their growth a much drier and cooler atmosphere is desirable, provided the plants are not exposed to extremes of either droughts or colds for too great a length of time. In whatever state the plants may be, always avoid dry-air draughts. In growing the " Calisaya " the most suitable climate would in general be that of a house, treated in the same way as one for Mexican and Guatemala Orchids, where it is easy to avoid too much heat and moisture during the season of rest, and to give a liberal supply of both, with ample shade, when making new growth. The " Calisaya " is increased either by seeds treated as above stated or by small lateral shoots as cuttings, when half ripened or just before the young wood becomes of a brown colour. The cutting should be taken off with a heel, close to the previous growth, and placed in silver sand, with as many of the leaves upon the cutting as possible. The pot containing the cuttings must be plunged in a slight bottom heat, and be covered with a bell- glass, and afterwards treated in the usual way. The seeds should be sown whenever received, whether in mid-winter or at any other time. This plant is too difficult to manage and requires too much attention to become very common, especially as it is not very showy when in bloom, although remarkably fragrant and singular for its panicles of small hairy white flowers, slightly tinged with blush on the outer side, in form much like those of the common Lilac. It commences flowering about the end of August, and Mill con- u 2 276 ^'^E^^' I'l.ANTS, ETC., tinue in succession at least a month, each flower lasting only two days, after which time it drops off before fading. 10. Ceanothus verrucosus. Ntittall, in Torrey and Gray, Fl. N. Amer., i. 267 ; Hooker, in Bat. Mag., t. 4660. Raised from seeds collected by Hartweg in California, and received at the Garden, June 5th, 1848, as " a shrub 8 feet high, growing on the Santa Cruz mountains." This proves to be a hardy evergreen of the best kind. It forms already a large bush, and will probably become a tree with long stiff rod-like downy branches, covered in winter with multi- tudes of large oblong or roundish brown buds. The leaves are opposite, roundish oblong, either slightly notched or entire at the end, scarcely an inch long at the largest, flat, deep green, shining, with grey hairy pits distributed over all the under surface. Occasionally, when the plant is young, they are coarsely toothed, as is represented in the Botanical Magazine ; but that is an ex- ceptional state : the usual condition is what is shown in the annexed cut. At the base of each leaf is a pair of stipules, which gradually lose their thin extremities and change into soft fleshy conical prickles. The flowers are very pale blue, produced in great abund- ance in dense corymbs at the end of very short stiff lateral branches. This shrub is among the most easy of plants to grow, and seems indifferent to climate or soil. It is increased by cuttings of the half-ripened wood, placed in sand under a hand-glass in a north aspect about the end of August. It is, however, best propagated by layering in the autumn. It flowers in June. It may be added that with the single exception of C. cuneatus^ a white-flowered species of little beauty, all the Californian Ceanothuses prove to be hardy near London. It is only requisite that they should not be placed in soil which keeps them growing till late in the year, but that their wood should be well ripened. In the Botanical Magazine Sir Wm. Hooker, in speaking of C.rigidus, observes that — " The North-west American Ceano- thuses are particularly deserving of cultivation in the open ground ; but it may require a Devonshire climate to bring them to the state in which they are at Bishopstowe, as just announced to me in a letter, dated 27th May, 1852, of the Bishop of Exeter. ' The Ceanothus divaricatus is now in its highest beauty : the largest plant is eighteen feet high, eighteen feet wide, twelve feet deep {i. e. from back to front), covered with thousands of the beautiful thyrsoid flowers, so that the leaves are hardly visible. C. rigidus blossomed about six weeks ago ; C. dentatus is now in full flower ; C. papillosus is just coming into flower ; C. azureus will not blossom before August.'

Received from Messrs. Riuz, of Frankfort, in April, 1852. Tliis is a soft smooth pale green slirub, with a fleshy tuberous root, like some Fuchsias. The leaves are stalked, almost wholly smooti), oblong-lanceolate, acuminate, nan'owed to the base, where they terminate abruptly in a rounded manner, strongly serrated, and furnished witli deep lateral diverging veins, which give the leaves tlie appearance of a Hornbeam tree's ; at the base they are furnished with a pair of red pyranndal short glands. The flowers stand on long slender stalks, singly in the axils of leaves, are as lai'ge as those of a Fuchsia globosa, and of a very ileep rose colour, which pervades every part except the anther, winch is blue. At first siglit this plant would not be taken for a Lopezia, the sepals being altogether petaloid, and the glandular knee peculiar to two of the petals of the genus seeming to be absent. But it will be found upon a careful examination that the knees are really present, only they stand very low down on the petals, so as to be concealed by the other parts. The name here employed, but w ith some doubt, is that under which M. Planchon has given it in the Flore des Serres. It seems impossible that it can be the plant which Mr. Bentham first described as Lopezia niacrophylla, in the Plantse Hart- wegianse, a shrub witli downy leaves and terminal panicles of flowers. That species I susjject exists in tlie Society's Garden, from Mr. Skinner, but, not having flowered, cannot at present be identified. Till materials accumulate for the satisfactory settle- ment of tin's question the name employed by M. Planchon had better stand unchanged. It is a green-house soft-wooded shrub, growing freely in a mixture of sandy loam and leaf mould, and requiring tlie same treatment as a Fuchsia. It is increased by cuttings put in sand under a bell-glass, and flowers during winter and spring. It is likely to be valuable as a winter flowering plant, notwith- sianding that it is coarse in folia-'e and habit. 12. Senecio concolor. De Cand., Prodr., vi. 407. Received from Sir Charles Hulse, Bart., in August, 1852; said to have been raised from seeds sent from the Cape of Good Hope by Colonel G. Buller. We have little doubt that this fine showy peremiial is that FROM THE SOCIETY'S GARDEN. 279 which De Candolle meant by his S. concolor, from Tulbagh and the Kat River mountains, although in cultivation it scarcely produces any of the hairs to which his specific character points. It is evidently a near relation of the old Senecio speciosus. The root leaves are spathulate, lanceolate, long-stalked, sinuated to- wards the base and toothed ; the leaves next above them are oblong and stalked ; the liighest are sessile, and slightly stem- clasping and downy at the edges ; all are more or less incised. The stem grows about 2 feet high, and forms an open corymb scantily clothed witli foliage. The flower-heads have a rich purple colour throughout, with a diameter of nearly two inches, most of which belongs to the rich purple ray. It is a greenhouse herbaceous j)lant, and requires to be treated like Cape Pelargoniums. It grows freely in a mixture of loam, peat, and leaf mould, and is increased from seeds. It is a very handsome plant, in the way of a " Cineraria," and may prove useful for bedding out during the summer. It flowers in Au- gust and September. 13. CuRYSEis (Eschsciioltzia) CALIFOKNICA ; viir. cilbijlora. Raised from seeds received from M. Vilmorin, as " Esch- scholtzia californica a fl. blanches," and from Mr. Charlwood as a " new white Eschscholtzia," in Fe- bruary, 1852. This plant is hardly distinct from the Eschscholtzia, or Chrj'seis californica, but it is remarkably different in having pale cream- coloured flowers, which are somewhat smaller. Like that species it must be sovn in the open border in the spring, and treated as a hardy annual. It is a very nice hardy plant, flowering all the summer. 14. Ophioxylon majus. Hasskarl, in Walpers' Repertorium, vi. 467. Received from Dr. von Siebold, August 18th, 1850, under the name of Ophioxylon album. There has been a diflference of opinion among botanists whe- ther there are one or two species of Ophioxylon ; but the ques- tion would seem to be set at rest by Mr. Hasskarl, who describes this plant as being altogether stronger in growth, with a smooth shrubby stem 4 feet high, leaves gi*een beneath, white flowers, and oli\'e-shaped fruit, while in O. serpenlinum this plant does not grow above a foot high, is not a slirub, has leaves red under- neath, larger reddish flowers, and globose fruit. The large 280 NEW PLANTS, ETC., white flowered plant, O. majus, tliought by Hasskarl to be possibly the Ophioxylon album of Gerstan, forms in the stove a small light green shrub with oblong-lanceolate membranous leaves placed in threes or fours, and loose cymes of white flowers. The corolla is nearly three quarters of an inch long, with the lobes of fhe limb half circular. It is a stove shrub, growing freely in a mixture of sandy loam and peat ; but requires to be kept in rather a moist atmosphere. It is increased by cuttings put in sand under a bell glass, and plunged ill tiie bark bed. Flowers in April and May. The plant is of little value in a horticultural view, the white flowers being too small to produce a striking effect. It is however of some medical interest, being one of the plants whose roots are be- lieved by Indian practitioners to be a cure for the bite of venom- ous serpents. 15. Centbanthus macrosiphon. Boissier. Paxton's Flower Garden, vol. ii. t. 67 ; var. albiflora. Raised from seeds received from M. Vilmorin, January 1852. ^ This differs in no respect from tlie original long-flowered Centranth, except in its flowers being pure w hite. It is a good hardy annual, growing freely in any good rich garden soil, and increased by seeds sown either in the autumn or spring, in the open border. It flowers in July and August. 16.

A plant was received from Isaac Anderson, Esq., of Edin- burgh, Oct. 16, 1850. A decvunbent, branching, entangled, viscid, hairy, brown- stemmed annual. Leaves pinnated, witii pedicellate lanceolate incised divisions, the uppermost ternate, the lowest of 3 or 4 pairs with an odd leaflet very much larger than the others. Flowers in pairs, in the axils of every one of the upjjer leaves, on slender stiff" stalks covered closely with spreading brown glandidar hairs, as also is the calyx, the lobes of wdiich are mcised. Corolla hairy externally, small, but a brilliant pure yellow; its upper lip hardly so long as the calyx, the lower lip obovate and nearly sessile.

Seeds very small, smooth, cinnamon-coloured, oblong, strongly ribbed. A half-hardy annual ; with the same kind of treatment as the small Blue Lobelias, it flowers all the summer and autumn, if planted in rather a moist situation. It is very pretty, and a most abundant flowerer, well suited for planting in the American border. 17. Cerasus laurocerasus ; var. Pumilio. This is a curious dwarf variety, resembling the common Laurel in much the same way as the Clanbrazil Fir resembles a Spruce. The leaves are from 2 to 3 inches long, and the habit extremely dwarf. If it does not hereafter run away, it will be a useful variety for places where the common Laurel is too large. A plant was received in 1851 from Lieut. -General Monckton, F.H.S., whose brother's gardener, William Reynolds, raised it from seed of the common Laurel. 18. Hedychium flavescexs. Loddiges, Bot. Cab., t. 723. Received from Dr. Siebold in August, 1850, under the name of Hedychium Roxburghii. A stout plant, about 4 feet high, with a great fleshy rhizome.. Leaves about 15 inches long by 5 inches broad, covered on the under side with long silky hairs. Flower spike erect, a foot long, covered with brown hairs. Outer bracts rather distant, 2 inches long, with a short leafy revolute point, and closely covered with rusty hairs at the edges ; rolled round a very short spike of 5 flowers, surrounded by membranous, nearly-smooth bractlets. Ovary and long tubular calyx shaggy with brown hairs. Tube of the corolla smooth, slender, 4 inches long ; its 3 outer petals linear and revolute ; of the pale yellow 3 inner, the lateral are unguiculate, spathulate-lanceolate, acuminate, slightly toothed ; the lip is unguiculate, deeply 2-parted with half-oval divisions, about half the length of the bright orange- coloured filament. The flowers emit a very agreeable spicy fragrance. It requires to be potted in a rich loamy soil, and to be placed in the dampest part of the stove while in a growing state; after- wards it should be removed to a cooler and drier place to bloom ; after flowering it should be dried gradually, and rested for about a month. It blossoms in September. It is a very fragrant plant, and rather showy, but remains only a short time in bloom. / 282 NEW PLANTS, ETC., There is no doubt about its being the H. Jlavescens of the Botanical Cabinet ; but I should have thought it to be also H. villosum of Dr. Wallich, if that plant had not been described as having 5 linear petals, whereas here 3 only are linear and 2 broad spathulate-lanceolate. 19.

A herbaceous plant, with a slight tendency to climb. The whole surface soft with down. Leaves roundish, oblong, mucro- nate, nearly sessile. Flowers few, pale greenish-yellow, in nearly sessile cymes, with slender pubescent flower-stalks. A perennial, supposed to be hardy or half-hardy, growing best in the peat border, and increased by division of the roots when in a dormant state. It is, however, of no kind of horticul- tural interest. It flowers in July and August. 20. Myrica californica. Chamisso and Schlechtendahl^ in Linncea, vi. p. 535 ; Hooker, FL Bor. Am., 2, 169; Botany of Beechey, p. 391. Raised from seeds collected by Hartweg, in California ; received at the Garden June 5th, 1848, and said to be collected in woods near Monterey, growing 12 feet high. This was originally gathered by Menzies on the north-west coast of America. Douglas found it at Puget Sound. It forms an evergreen bush, with dense narrowly lanceolate, slightly ser- rated leaves, covered, especially on the under side, with transpa- rent, glossy, saucer-shaped sunken scales, of microscopical dimen- sions, consisting of a layer of wedge-shaped cells, placed obliquely round a common centre. The flowers are green and inconspi- cuous, in short axillary spikes, which eventually bear from 1 to 3 small globular fruits, whose surface is closely studded with fleshy, oblong, obtuse grains of a dull I'ed colour, and astringent flavour. It is a hardy evergreen, growing freely in any good garden soil, increased by seeds or by layers, in the usual way. It flowers in July, and produces in September an abundance of its little granular fruits. In gardens it is an acquisition, being a hardy shrub, with fragrant lea\ es. and well suited for rock-work or for the front of a slu'ubbery.

Raised from seeds received from Mr. W. P. Ayres, in February, 1851. This species was first made known through Sir William Hooker's Icones, by Mr. Hewitt Watson, to whom it was given by Captain Vidal, R.N., whose name it bears. It was found on " an insulated rock off the east coast of Flores, between Santa Cruz and Ponta Delgada." Seeds were received some time since from Mr. Ayres, w ho was indebted for them to Mr. P. Wallace. The plant has a fine handsome deep green shining succulent foliage, and forms a very good-looking decumbent shrub. Some of the shoots are merely terminated by long rosettes of leaves, others throw up an erect graceful, flowering stem, with a shiny surface, and a warm greenish-brown colour, terminated by several large white nodding flowers, each about H inch long, and shining as if glazed. The colour is however bad, a tint of dull purple or even pale cinnamon giving them a dirty appearance. It is a half-hardy or greenhouse shrub, growing best in a mix- ture of sandy loam and leaf-mould, increasing freely by seeds, but not flowering before the second season from seed. It blossoms in August, and is a good object for rock-work in a climate which suits it ; but, being tender, its value is much diminished, inde- pendently of the dingy colour of its flowers. This plant has so little the appearance of an ordinary Campa- nula that it is a question whether it truly belongs to the genus. It would rather seem to be related to Musschia, the old Campa- nula aurea, though by no means to be associated with it. The ovary is 3-celled, witli a great rugged double placenta expanding in each cavity, and around the flat head of the ovary, inside the corolla, there runs a broad yellow fleshy ring-like disk ; but neither in this nor in any other circumstance, except habit, does there appear to be real ground for generic separation. 22. ViNC'EToxicuM purpurascens. Morren and Decaisne, in the Bull. Acad. Brux. 1836, p. 17. Received from Dr. Siebold, in August, 1850, under the name of Cynanchum purpurascens.

It was in tlio way of C. ^rall'ne cristata, covered with flowers; An- sellia africana ; the white-blossomed Dendrobium Heynea- num, perhaps in better condition than it had ever been seen in before ; a fine plant of Epidendrum odoratissiinum, and one of the higher coloured varieties of Lycaste Skinneri. Banksinn Medal : — To Messrs. Standish and Noble, of Bagshot, who furnished on tliis occasion the first example of a new Sikkim Rhodo- dendron in flower. It was named R. ciliatum, and is really very handsome, the flowers being blush, shaded on the outside with pink, very large for the size of the plant (which was scarcely 6 inches high), and well formed. The leaves were small, pale green, and covered with long hairs. It was mentioned that, owing to its dwarf habit and large blossoms, it would be valuable in the hands of the hybridist for dwarfing and giving a more desirable habit to some of our already existing kinds. The specimen sent had been forced ; and therefore under out-door culture, if it should prove to be hardy, which is expected, the flowers will no doubt become deeper in colour. Messrs. Standish state that " the merits of this Rhododendron consist in its sin- gular foliage, dwarf habit, and freeness to bloom. The seeds from which the plant in question was raised were sown on April 20th, 1850. From the following experi- ment it appears to be quite hardy. In the autumn of 1850 (with the exception of R. Dalhousiae) we had samples of all the Sikkim Rhododendrons planted out in a cold frame. They were exposed by day to the open air, and covered up at night. One night, in February, 1851, they were left uncovered by mistake, and although in a small state (with the exception of R. argenteum) they withstood 10 deg. of fro:it without injury, and argenteum was only slightly XXIV PROCEEDINGS. hurt, and recovered during the following summer. The White Tree Rhododendron, sown and treated as the above, suffered much the same as R. argenteum. Again, in Sep- tember last we had a sharp frost which cut the young leaves of R. ponticum, while the Sikkims in the same bed were uninjured, and during last month they again with- stood 16 deg. of frost without injury. Owing to its very dwarf and compact habit, together with its freeness of flowering, the species uniler notice will be very useful for many gardening purposes." To Messrs. Jackson, for Maranta (?) sanguinea, a South American plant, which they have succeeded in flowering at Kingston for the first time in England. It requires a stove, and is valuable for its handsome foliage and, as it proves, for the beauty of its flowers. Certificate of Merit : — To Mr. Atkins, of Painswick, Gloucestershire, for a very handsome Cyclamen, the produce of a cross between C. persicum and C. Coum, It partook very much of the habit of the latter, w hile the flowers and leaves had the colour of persicum. To Mr. Mitchell, of Brighton, for nice bunches of Black Hamburgh Grapes, just ripened. III.— MISCELLANEOUS SUBJECTS OF EXHIBITION. Messrs. Rollisson sent a small but curious form of Cycnoches, (musciferum) which was apparently new to gardens. It was stated to have been purchased at one of Mr. Linden's sales. Messrs. Hayes, of Edmonton, sent two single fringed seedling Chinese Prinmlas. One had handsome, large, bright rosy purple flowers ; the other was chiefly remarkable for its stiff' dwarf habit and disposition to curl, which was strikingly observable in the leaves. From Messrs. Veitch came a flowering branch of Acacia dealbata, together with the following letter respecting it : — "Having seen in the Gardener's Chronicle of the 28th ult. an account of the Acacia dealbata flowering against an open wall at Enfield, we send a specimen in fine bloom, from a standard tree which grows in our private ground at Exeter. It stands on the grass, is upwards of 20 feet high, and from 18 to 20 feet through the middle, feathered to the ground, forming a beautiful compact tree, and covtrtd with floMers similar to the specimen PROCEEDINGS. XXV sent. We have never given it any other shelter than a hayband twined round the stem for about 6 feet, as a precaution in case of very severe frost ; it has been in its present situation about 8 or 10 years, and has never been injured in the least by the "weather. It ought, perhaps, to be remarked that it had been planted against a wall four or five years previously to its being removed to its present situation." A Eipley Queen Pine-apple, weighing 3 lbs. 3 ozs., was com- municated by Mr. Jones, gardener to Sir J. Guest, Bart., F.H.S., Dowlais House, Glamorganshire. "New yellow crowned" Seakale came from Mr. Prestoe, Gardener to E. W. Blunt, Esq., of Kempshall Park. IV.— NOVELTIES FROM THE SOCIETY'S GARDEN. An interesting example of the Nepal Ash-leaved Berberry (Berberis nepalensis). The main stem, in this instance, termi- nated in a cluster of six spikelets (each nearly 6 inches long) of fine dark yellow flowers, which, if it should fruit in tliis country, will be succeeded by beautiful purple oblong berries. The leaves are of a yellowish green, large, and very handsome ; and if the plant should prove to be hardy, it will certainly be a very great acquisition to British gardens. It was mentioned that Mr. Fortvme had met witli a Berberry (not B. japonica) very much like it in China, and that another (the Acanthus-leaved Ber- berry) resembling it, but still very different, and probably handsomer, was to be found in the Neilgherries. Tins, which has round fruit (not oblong), may, however, be more tender than nepalensis, which comes from the more northern Himalayas. It was stated that persons in correspondence with the Madras Presidency could easily obtain fruit of the Acanthus-leaved Berberry from Ootacamund. Cuttings of the following fruit trees were distributed : — Heine Hortense Cherry. — Syn. Monstrueuse de Bavay, Le- mercier. Belle de Laeken. It is said to have been found at the Carmelite Convent, at Vilvorde, in Belgium. Fruit very large, bright red, and of first-rate quality. Kipens in July. T'riomphe de Jodoiyiw Pear. — The tree is vigorous, and it is said to be an abundant bearer. Fruit very large, short pyri- form, melting, and excellent, becoming fit for use in De- cember. The above are new sorts, that have not yet fruited in the Garden. The following are better known : — PllOCEEDINGS. Claygate Pearmam. — A first-rate apple for December and January, or even later. The flesh is yellowish, rich, and sugary, partaking of that Ribston pippin flavour which is so rarely found in apples. Fiji Ap2)le. — The cuttings of this have been presented to the Society by J. Disney, Esq., F.H.S., The Hyde, Ingatestone. It is a very handsome, middle-sized, round apple, of a fine pale yellow colour, with a delicate blush next the sun. It is likely to prove a good kitchen apple. The tree is a very abundant bearer : it is remarkable as a seedling of the Ribston pippin, without a trace of the colour, form, or quality of that variety. v.— BOOKS PRESENTED.

Banhsian Medal : To Mr. Meredith, Gardener to the Duke of Sutherland, F.H.S., at Cleifden, for an admirable specimen of a Hybrid Bego- nia, raised between B. manicata and hydrocotylifolia. It had the general aspect of the latter, but added the constitu- tional vigour and some other peculiarities belonging to manicata ; while altogether it was a more desirable plant than either of its parents. To Mr. May, Gardener to Mrs. Lawrence, F.H.S., for fine plants of the Hong Kong Enkianthus reticulatus, the charming Boronia triphylla covered with pink starry flowers, the white Eriostemon scabrum and Styphelia tubiflora. To Mr. Ingram, Gardener to Her Majesty at Frogmore, for a Cayenne Pine Apple, weighing 7 lbs. 2 oz. PROCEEDINGS. XXVU Certificate of Merit : — To Messrs. Henderson, Pine Apple Place, for a beautiful specimen of Dielytra spectabilis, whose flowers were, how- ever, somewhat deficient in colour, owing to their having been produced in too much heat. It was mentioned that a good way of having this useful Fumewort in perfection in early spring is to take plants from the open border, pot them, and bring them on in a cold house or frame, from which they can be transferred to the green-house, conser- vatory, or other suitable place to expand their blossoms in. After flowering they may be returned to the open border. To Mr. Franklin, Gardener to Mrs. Lawrence, F.H.S., for an interesting specimen of the Long-tailed Lady's Slipper (Cypripedium caudatum). To Mr. Tillery, Gardener to the Duke of Portland, at Wel- beck, for ripe fruit of the Japan Medlar (Eriobotrya Ja- ponica), which was accompanied by the following remarks: " The fruit of this Medlar is much esteemed here, and coming in, as it does, at a time when other dessert fruit is scarce, makes it still more valuable. The tree from which the sample sent was taken has produced three or four dishes every week for the last six weeks, and there is still a con- siderable quantity to gather. The tree fills one entire house, which is devoted to its culture, and the following is the mode I find to be the best for successfully fruiting it. Li the summer months, after the young growths are made, all the air that can possibly be given is supplied by taking oflT some of the lights of the house. At the flowering time, which is in September and October, the house is shut up, and a stove temperature maintained all the winter afterwards. The fruit begins to ripen by tlie beginning of February, on the early flowering clusters, and a regular succession is kept up for a long time. The flowers are deliciously sweet scented, and, along Avith magnificent foliage, the plant is well worthy of a place in any stove." III.— MISCELLANEOUS SUBJECTS OF EXHIBITION. Mr. Meredith sent from Cleifden a very fine plant of Bego- nia manicata, and a large and beautiful bouquet, with a view to illustrate a good mode of packing such things for travelling. Two parallel lines of string, about an inch apart, were fastened between the four opposite sides of a square wooden box so as to intersect each other in the middle ; but at different levels. The shank of the bouquet was then passed down where the lines inter- XXVIU PROCEEDTNGS. sect, embedded up to the flowers in damp moss, and tied firmly to the bottom of the box. In this way the bouquet is kept fast in one position and travels safely. Messrs. Henderson, of Pine Apple Place, furnished Epacris h5^acintliiflora candidissima ; a curious little deep yellow-flowered Acacia called squamafa, with needle-like processes in tlie place of leaves ; and four plants of tlie Cape Lachenalia luteola. From Messrs. Jackson, of Kingston, came two seedling Camellias, named Duchess of Buccleuch, and Martinii. The latter is a promising deep crimson-flowered kind, with a white stripe down the centre of each petal. Mrs. Lawrence contributed Lycaste Skinneri, and cut flower spikes of Amherstia nobilis. It was mentioned that at Ealing Park the Amherstia is now as large as a good-sized apple-tree, that it has been in flower ever since Christmas; that nearly 170 spikes of its inflorescence have been cut from it ; and that about as many more yet remain on the tree. An example of the Sikkim Rhododendron ciliatum, of which a good specimen was shown at the last meeting by Messrs. Stan- dish and Noble, was furnished by Sir Joseph Paxton, from Chatsworth. On this occasion it was quite colourless ; but whetlier this was constitutional, or merely the effect of circimi- stances, could not in the present instance be clearly determined upon. Mr. Ingram sent from Frogmore a pretty Epacris, a seedling from miniata. IV.— NOVELTIES FROM THE SOCIETY'S GARDEN. A very profuse-flowering pink Azalea sent from China by Mr. Fortune ; Rhododendron Nilagiricum, an exceedingly hand- some kind, with round compact heads of bright rose-coloured flowers, that become paler as they get older ; and an interesting bush of Forsythia viridissima. Cuttings of the following Pears and Apples were distributed : — Pears : Jersey Gratioli. — Fruit of a good size, roundish ; the eye in a very even depression. Skin pale brown, somewhat rough, with russeted specks. Flesh melting, like honey, and exceedingly rich. Ripens in October. The tree is likely to prove an excel- lent bearer. March Bergaraot. — Of all the varieties of Pears raised by the late Mr. Knight, this ripens the latest. It was named the March PROCEEDINGS. XXIX Bergamot from its keeping till March ; but it will generally keep later ; and it will succeed where the Belgian late pears, the Easter Beurre, and Beurre Ranee, will not. The fruit, resembles the Autumn Bergamot in form and size ; skin yellowish-brown, partially russeted. Flesh buttery and rich. Cerise de Spa. — This has not been fruited in the garden. It was received from Louis Van Houtte as a new sort. In M. Bavay's Catalogue general des Pepuiieres Royales de Vilvorde, near Brussels, the tree is described as being vigorous, and an abundant bearer. Fruit large, red, and of first-rate quality, ripening in July. Millfield Apple. This appears to be a new sort, originally received by the Society from Messrs. Young, Nurserymen, Epsom, Fruit middle-sized, roundish, or somewhat pearmain shaped. Eye large, moderately deep. Skin greenish-yellow on the shaded side, reddish and obscurely streaked next, the sun. Flesh yellowish and rich. In perfection in December and January. v.— BOOKS PRESENTED. Palms of British East India, by the late William Griffith, Esq. ; from the Hon. the East India Company.

It was announced that the Council had recommended that H.R.H. Prince Albert and His Imperial Majesty the Emperor of Russia, now Fellows of the Society, should be nominated Hono- rary Members in two vacancies existing ; whereupon H.R.H. Prince Albert and His Imperial Majesty the Emperor of Russia were balloted for, and duly elected Honorary Members of the Society. II.— AWAEDS. Large Silver Medal : — To Messrs. Veitch, for Phalsenopsis Lobbii, a highly promising species, uniting the colovxr of P. rosea with the large blos- soms of P. amabilis. The example exhibited was small, having been but recently imported, and only flowering for the first time : but it served to show what may be expected from larger and better established plants. Knightian Medal : — To Mr. Franklin, Gardener to Mrs. Lawrence, F.H.S., for a collection of Orchids, containing Dendrobium nobile, the Rhubarb-scented D. macrophyllum ; a Maxillaria, la- belled a variety of M. Harrisonise, but, probably, a dif- ferent species, and much handsomer ; the Brazilian Onci- dium sarcodes, Trichopilia suavis, and Ly caste gigantea. Banksian Medal : — To Messrs. Henderson, of Pine Apple Place, for a collection of Hyacinths. The names of some of tlie best were : Light blue — Orondates, Robinson, Pasquin, Prince Frederick, Nimrod, Grande Vidette, Grand Lilac, Morello, and Passe tout (double). Dark blue — Laurens Koster (double), Prince Van Saxe Weimar, Amicus, Richard Coeur de Lion (very fine), Baron Van Thuyll, Charles Dickens, Prince PKOCEEDLNGS. XXXI Oscar, and Mignonaude Drythout (double). Violet — Tubal Cain, William I., and Prince Albert. White — Helen, Grand Vainqueur, Le Tour d'Auvergne, La Vestale, Grande Vidette, Prima Donna, La Candeur, and A la Mode Epuisee (double, witli a pink centre). Blush — Grandeur de Me- neilles, Anna Maria (double). Triumph Blandina (ditto), and Tubiflora. Plum — L'Unique. Yelloiv or buff — Miss Kitty (double, very fine), Anna Paulowna, Heroine (double). Deep rose — Amphion. Red — Fireball, Mars, HersteWe Vreede, Appelius, Le Francq Van Berkhey, and Waterloo (double). Light red — La Dame du Laak, and Lord Wel- lington. Of these perhaps the most remarkable for general good properties was Richard Cceur de Lion, single blue, very similar in colour to Charles Dickens, Bleumorant, Prince Oscar, and Baron Van Thuyll, but infinitely sur- passing them in quality ; tube smooth, as were the several divisions of it, glossy, broad, and of good size ; in truth the best of all the single varieties displayed on the occasion. Appelius and Fireball, single reds, were brighter in colour and better in form than Waterloo. Prince Frederick and Pasquin were the best of the double blues, and distinct ; Miss Kitty was conspicuous for its large bells, but they were rather thinly arranged on the spike. Prince Albert must still be considered one of the darkest Hyacinths in cul- tivation. These were all in ordinary shaped, rather small- sized pots, in each of which were two plants, and sometimes three, which made a very effective display. To Messrs. Lane and Son, of Great Berkhampstead, for a col- lection of cut Roses, gathered from a house heated on the Polmaise principle. They consisted of some of the best of tlie Hybrid Perpetual, Bourbon, and Tea-scented kinds, as Apollon, Baron ne Prevost, Chateaubriand, Cornet, Duchesse de Praslin, Due d'Alencon, Duchess of Sutherland, William Jesse, Geant des Batailles, General Negrier, Madame Tru- deaux, Soleil d'Austerlitz, Standard of Marengo, Armosa, Madame Angelina, Paul Joseph, Queen, Souvenir de la Malmaison, Mrs. Bosanquet, Belle Allemande, Comte de Paris, Moire, Smith's Yellow, Vicomtesse Decazes, For- tune's Double Yellow, and others. Certificate of Merit : — To Mr. Turner, F.H.S., of the Royal Nursery, Slough, for six sorts of Pansies, in pots, consisting of Duke of Norfolk, Sir Philip Sidney, Disraeli, Ophir, Robert Burns, and Eu- phemia. These were exhibited to show the value of the d 2 XXXll FROCEKDINGS. Pansy as an early blooming- plant. They had been in flower about a month, and they were still covered with blossoms, which, under proper treatment, would continue to be produced till the end of May. They had been grown in a common 3 light box, from which the liglits were removed during fine weather. To Messrs. Veitcli, for a Posoqueria (?) from the Organ mountains, possessing an elegant habit, and bearing quanti- ties of long creamy white, peculiarly scented flowers. To Mr. Chapman, Gardener to J. B, C41egg, Esq., F.H.S., for a smooth-leaved Cayenne Pine Apple, weighing of Ib^. To Mr. Allport, Gardener to H. Akroyd, Esq., Doddington Park, Nantwich, Cheshire, for a dish of black Hamburgh Grapes. To Mr. Law, Gardener to E. J. Sliirley, Esq., of Eatington Park, Stratford-on-Avon, fur a dish of forced Peaches from trees growing in pots. They \^•ere quite ripe, but not very large or well coloured. To Mr. M'Ewen, Gardener to the Duke of Norfolk, F.H.S., at Arundel, for five pots of Keens' Seedling Strawberry, and one of Alice Maude. They were loaded with large and well-ripened fruit. Concerning the kind of treatment they had received Mr. M'Ewen says: — '' We begin putting the early runners in 3-inch pots about the middle of June, and not later than the middle of July. They are transferred as soon as rooted into the fruiting pots, which are well drained and filled with soil composed of three-fourths sandy loam and one-fourth decayed night-soil and leaf-mould. The pots are then placefl on boards in an open square of the kitchen garden, and plunged in any light material. This prevents frequent watering ; the plants are placed so thin that not a leaf of one touches another. Wiien the pots are well filled with roots we water twice a week with liquid manure. In the winter the pots are placed on their sides so as to form a riilge. They are forced by introducing them for a few days into cold frames and pits, and they are Jloivei^ed, set, and swelled ojf on a spare shelf at the very top of a fruiting pine pit, in a heat ranging from 70° to 75°, sometimes 20° more. To flavour them we place them in a cold frame, and in fine weather expose them fully for three or four days." III.— MISCELLANEOUS SUBJECTS OF EXHIBITION. Messrs. Henderson sent a little tree of the Oleander-leaved Eriostemon, and a nice pyramidal plant of E. intermedia ; also PKOCEEDINGS. XXXlll the pretty Boronia triphylla ; a variegated-leaved Coronilla glauca ; Elseocarpus deutatus ; a species of Aotus ; and two dwarf, compact, free-flowering' Rhododendrons. Mr. Jones, Gardener to Sir J. Guest, Bart., F.H.S., furnished three Ripley Queen Pine Apples, weighing respectively 4 lbs. 2 oz., 3 lbs. 13 oz., and 3 lbs. 10 oz. A plan for labelling Roses, the invention of Mr. Bohn, of York Street, Covent Garden, was brought under the notice of the meeting by the Rev. W. B. Hawkins, F.H.S. In a letter relating to these labels Mr. Hawkins says : — " Mr. Henry G. Bohn, the eminent publisher, of York Street, Covent Garden, and of North End House, Twickenham, who has paid consider- able attention to horticulture, and particularly to the cultivation of roses, lias written to me describing a mode of labelling these plants adopted by him in his garden, which appears so ingenious, and is at the same time so practicable and ecoiiomical, that I think it should be brought before the notice of the Society. Mr. Bohn's plan is this : he uses a paper label, at one end of which is printed the name of the rose, and at the other end the colour and general description of the plant ; this label is then folded in half and pasted back to back ; it is then cast in a small flat tube of glass, closed at both ends, with a ring (in glass) at one end to hold the soft wire by which it is to be sus- pended from the plant. The following extract from Mr. Bohn's letter will perhaps aflbrd a better explanation of Jiis plan. He says, ' You seemed to think that tlie Society would like to see my plan of labelling Roses, and proposed to bring it to their notice at the next meeting. With that object I have the plea- sure of sending you the first complete set of labels which has been received from the printer's, together with a sample of the mode of applying them. Glass tallies have been before the public for some time, but they did not answer well, as the lead or putty with which they were closed was prettj"^ sure to drop out. Mine are the first, I believe, which are cast with the label inside, and though I now find plenty able to do it, I was told by several, when the idea occurred to me, that it could not be done. Having upwards of a thousand roses, printing the labels is to me a matter of economy as well as of convenience and neatness. The cost is not more t\ia,n five farthings per label — paper, print, and glass included. As all who have seen the plan approve of it very much, and several growers intend to adopt it, especially for Orchids, I^should be glad to have it seen previously by the Society.' " Specimens of the label in its glass case were exhibited. XXXIV PROCEEDINGS. IV.— PLANTS, &c., FROM THE SOCIETY'S GARDEN.

Standish and Noble, for Azalea amoena, a new species collected in the North of China by Mr. Fortune, and expected to prove hardy in this country. It has small, rather blunt leaves, and very small round rosy-purple flowers, looking like so many half-inverted bells, so that, independent of its beauty, which is great, it will be exceed- ingly interesting on account of the form of its blossoms, wliich are quite distinct from those of any Azalea yet introduced. To Messrs. Veitch, for Dendrobium albo-sanguineum. To Messrs. Loddiges, for a collection of Orchids, consisting of Vanda suavis, Saccolabium ampullaceum, Lycaste Skinneri, Dendrobium anosmum, a species in the way of but hand- somer than D. macrophyllum, and wanting the strong Rhubarb smell which belongs to the latter ; Oncidium bi- folium, Dendrobium chrysotoxum, Aerides affine, Laelia cinnabarina, and a white Angrec from Algoa Bay.

To Mr. Forbes, Gardener to the Duke of Bedford, F.H.S., at Woburn, for four bunches of Black Hamburgh Grapes. To Mr. Meredith, Gardener to the Duke of Sutherland, F.H.S., at Cliefden, for eight pots of Keens' Seedling Strawberry, in fruit, and a similar number of Cuthill's Black Prince, the latter being in 3-inch jiots and well fruited. To Mr. Lewis Solomon, of Covent Garden Market, for ex- amples of Paris Cos and Grand Admirable Lettuces, im- ported from France. Tlie attention of the meeting was di'awn to the fact, tiiat the only persons who in this country succeeded in producing fine Summer Lettuces at this season in England were two Dutch gardeners, one of whom was brought over by the late Mr. Labouchere. II.— MISCELLANEOUS SUBJECTS OF EXHIBITION. A small piece of a flower-spike of the lovely Odontoglossum Pescatorei came from Mr. Mylam, Gardener to S. Rucker, Esq., F.H.S. A Dendrobe from Sylliet, apparently D. heterocarpum in a diminutive state, was furnished by Messrs. Jackson, of Kingston. Mr. Bunney contributed an imported plant of Dendrobium nobile. From Messrs. Backhouse, of York, came a Cattleya, named amethystina, but which appeared to be a variety of C. intermedia. A Thysanotus, from Ncav South Wales, accompanied it ; but in the absence of bright light, its flowers did not open. XXXVl PBOCKEDINGS. Mr. Ayres, of Blackheath, sent cut blooms of 24 varieties of fancy Pelargoniums. R. T. Clarke, Esq., F.H.S., exhibited cut specimens of a white Chrysanthemum in bloom, which proves that this useful autumn flower may be had in blossom at almost any season, if such should be desired. It had of course been forced. Messrs. E. G. Henderson sent a fancy Pelargonium named Annette ; two small Orange-trees, in order to siiow how freely they bloom in pots in a small state ; three Amaryllids, a collec- tion of Cinerarias, four Cyclamens, and six hybrid Rhododen- drons. Some seedling Auriculas were shown by Mr. Coldham, of Southgate. Mr. Sommersby, Gardener to Major Martyn, sent two dwarf Hydrangeas, and a white seedling Petunia. From Messrs. Henderson came a new yellow-flowered Indian Dendrobe ; a new Gastrolobium, the pretty Boronia tetrandra, the small growing free-flowering Eriostemon scabrum, and a species of Acacia. Mr. Wood, of Norwood, sent a collection of variegated hardy plants and a seedling Rhododendron with bright crimson flowers. A design for laying out ornamental grounds was shown by Messrs. Wood and Lake, land-surveyors, Lincoln's Inn Fields. III. -PLANTS, &c., FROM THE SOCIETY'S GARDEN.

The weather on this occasion was propitious, and the exhibi- tion everytiiing that could possibly be desired ; for not only were the plants produced admirable examples of cultivation, but they were furnished in such numbers that room under the tents could scarcely be found for them. Such Azaleas, Orchids, Roses, and Cape Heaths nobody ever saw in the Garden before ; and, considering the season, there was a good show of fruit. The number of visitors was 2755, exclusive of exhibitors and persons officially employed. L— AWAEDS.

Allnutt, Esq., of Clapham Common, furnished a large semi-double Azalea called Fulgens, and a hardy hybrid Rhodo- dendron which lie had found to flower well this year, while the blossoms of other hybrids of the same nature, associated with it, had been all killed by the cold winds and frosty nights of the late peculiar spring. From Mr. Fleming came two examples of the Trentham Hybrid Melon, weighing respectively 2 lbs. 10 oz. and 3 lbs. 4 oz. The true Bailey's Green-fleshed Melon, a round netted kind, weighing in this instance 5 lbs. 11 oz., was sent by Mr. Bailey, of Shardeloes Gardens, Amersham, who raised the variety from seed upwards of 20 years ago. It was stated by Mr. Bailey to be a finely flavoured variety. Mr. Smith, of Mauchline, in Ayrshire, exhibited specimens of what he called a " transplant sliade," which he expects will prove better than flower-pots for sheltering newly bedded-out plants, &c., from the heat of the sun in the day-time and from cold at nio-hts. He says, " Observing in the gardens of the surrounding nobility and gentry that when plants are first transplanted out they are usually covered from the solar rays by means of flower- pots inverted over them and propped up on one side to admit the air it struck me that this was at least not very craftsmanlike, and that it could not answer the purpose in the best possible way. I have made a model for an article intended to be formed of earthenware, and used for ' transplant shades.' It will be understood that these shades would be intended to stand on three short legs, so as to admit a fresh supply of air from all quarters, and that the other end is so contrived as to catch the quantity, PROCEEDINGS. xlv or nearly the quantity, of rain that would fall upon the space covered by the pot, and to conduct it upon the plant. In short, the advantages to be derived from my invention are — 1. It will stand perpendicular in its natural position, no tilting being required. 2. By merely putting it gently on the ground, or by pressing it more or less into the ground, the supply of air can be either regulated or excluded altogether. 3. The con- cavity at the top will receive either rain or artificial watering, and shower it on the plant and soil without exposing the gardener to the trouble of removing the shades." Two models were shown, one without a top, the other with a top perforated with small holes and surrounded by a rim. The fault of the first was stated to be, that it permitted radiation from the soil at night to go on about as freely as if the plant was exposed ; and that of the latter, that while it allowed water to pass through the top, it kept its inmate nearly as dark as under a common flower-pot. Instead of fixed perforated tops, or no top at all, it was suggested that moveable lids should be used, and then it was thought the contrivance might be an improvement on the common flower-pot for purposes of shading. IV.— NOVELTIES FROM THE SOCIETY'S GARDEN. A Diplacus raised from Californian seeds. It proves to be a very distinct and handsome kind, with large showy buff flowers shaded with salmon. The following proposed alteration in the by-laws was read a first time : — " The Council hereby give notice that they propose to substitute for Chapter 8, Article 1, of the present by-laws, namely, ' The number of honorary members shall not at any time exceed five,' the following words : — ' The number of honorary members shall not at any time exceed ten.'

Standish and Co., of Bagsliot, for a new Clematis (lanuginosa), found in the north of China by Mr. Fortune. It resembles C. azurea, but it is different from that species, and will probably be hardier. The blossoms are large and handsome ; but they were not seen under the best condi- tions, for the plant was small, and it had been forced into bloom somew hat prematurely. It was remarkable for the wool upon the back of the flowers and leaves. Certificate of Merit : — To Mr. "Waterer, of Bagshot, for a deep purplish crimson Rhododendron called Celebrandimi, with large heads of well-shaped flowers of good substance. It was stated to be a cross between R. maximum and altaclerense, and to be among the latest kinds known — a very important property, since it is thus secured against spring frosts. To Mr. Jones, Gardener to Sir J. Guest, Bart., F.H.S., for a Ripley Queen Pine Apple, weighing 5 lbs. 3 oz. To Mr. Chapman, Gardener to the Earl of Gainsborough, at Exton Park, Oakham, for two examples of a hybrid INIelon, weighing respectively 3 lbs. 8 oz. and 4 lbs. 2 oz. It was stated to be a cross between the Trentham Hybrid and a small Melon called the Chinese Green-fleshed. It had sometliing of the appearance of the Bromham Hall, and was found to be excellently flavoured. III.— MISCELLANEOUS SUBJECTS OF EXHIBITION. From Mr. Macintosh, Nurseryman, Stranraer-place, Maida Vale, came Cantua pyrifolia in bloom. It has fine glossy green leaves and pale lemon-coloured flowers, which are not, however, very striking. A cut specimen of a seedling Pelargonium, resembling Luceum roseum, was shown by Mr. Middlewood, of Hornsey-road. The Hon. W. F. Strangways contributed flowering branches of the following plants, which have been proved to be hardy at Abbotsbury, in Dorsetshire, viz., Veronica formosa, V. decussata, Melaleuca thymifolia, Echeveria secunda, Diplacus glutinosus, Epacris heteronema, Grevillea acanthifolia, Swammerdamia glomulifera. They were accompanied by Iris Monnieri, Gla- diolus Segetum, and a piece of a branch, split in two and nearly 2 inches in diameter, of Callitris quadrivalvis, a Coniferous tree inhabiting the mountains of Barbary, where it is called the Arar VOL. VII. f liv PROCEEDINGS. tree, and largely used for building purposes, it being remarkable for the durability of its wood. From Mr. Martin, Gardener to Sir H. Fleetwood, Bart., Hill House, Windsor Forest, came Elruge Nectarines and Black Prince and Black Hamburgh Grapes. Mr. Summerby, Gardener to Major Martyn, of Fern Cottage, Windsor, sent a specimen in a pot of what was considered by liim to be a new kind of Vine. It proved, however, to be only the Alexandrian Ciotat, a variety remarkable for its singularly cut foliage, but seldom cultivated on account of its want of pro- ductiveness and inferior quality, IV.— NOVELTIES FROM THE SOCIETY'S GARDEN. Cut specimens, in bloom, of the Californian Cerasus ilicifolia, or evergreen Plum, which is now flowering in the Garden for the first time. Its blossoms resemble those of a Portugal Laurel, and they are said to be succeeded by fi-uit as large as a Sloe, and which is eatable; but it was mentioned that as it belongs to a suspicious family, a trial of its eatable quality must be made with caution. The following proposed alteration in the by-laws was read a second time : — " The Council hereby give notice that they pro- pose to substitute for Chapter 8, Article 1, of the present by- liuvs, namely, ' The number of honorary members shall not at any time exceed five,' the following words : ' The number of honorary members shall not at any time exceed ten.'

The number of visitors on this occasion, exclusive of exhibitors and persons officially employed, amounted to 8820. The weatlier was extremely propitious, permitting an inspection of the beau- tiful grounds of Chiswick House, thrown open to the meeting by the noble President of the Society, to be made under the most favourable circumstances. The exhibition, too, was excellent — in some respects, perhaps, the finest of the season. The fruit, as usual, formed the most remarkable feature. I.— AWARDS.

Ill consequence of a .sufficient nuiiibei" of Fellows not being present on tliis occasion, a quorum was not formed. The fol- lowing subjects were, however, presented for exhibition : — Mr. Glendiniiing, F.H.S., sent a collection of Gloxinias, con- sisting of Teuchlerii, Wortleyana, Maria Van Houtte, Mrs. Griffiths, Rubra, Grandiflora, Baron Rozel, and the following new kinds: Albert Courtin, Souvenir de Bordeaux, Newelliana, and Huntleyana. Mrs. Lawrence, F.H.S., produced a handsomely flowered Epacris miniata, Saccolabium Blumei and anotlier species, and the variety of Aerides suavissimum called flavidum. Mr. Watson, gardener to Mrs. Tredwell, of St. John's Lodge, Norwood, had Clerodendron fcetidum. Mr. Ingram, of the Koyal Gardens, Frogmore, sent a very pretty hybrid Achimenes, with large handsome leaves and deep orange-scarlet flowers, lined up the centre of the petals with minute round black dots. It was stated to have been raised between A. oculata and A. picta. Bunches of the white Cor- niclion Grape, a large very fleshy variety, of second-rate value, also came from the same establisliment. As this now exists in many collections of this country, it may be as well to explain that it is very difficult to ripen, acquiring perfect maturity only in the long hot summers of Sicily, and similar parts of the Medi- terranean. AYhen ripe it is bright amber-coloured. Messrs. Veitch contributed 12 specimens of the early sweet- kernelled Kaisha Apricot, of which some account appeared in vol. iv., p. 189. It is by far the earliest Apricot of good quality in this country. Mr. Fleming, gardener to the Duke of Sutherland, F.II.S., at Trentham, produced a beautiful Moscow Queen Pine-apple, weighing 5i lbs. From Mr. Cuthill, of Denmark-hill, Camberwell, came ex- amples of tlie Lapstone Kidney Potato, wliieh, though a late sort, was nearly ripe. They had been treated according lo the plan published in his pamphlet on the Potato. Specimens of capital glass milk-pans, as cheap as any foreign ones, were furnished by Mr. Phillips, of Bishopsgate-street. II.— NOVELTIES FEOM THE SOCIETY'S GARDEN, A Californian Lily, with small reflexed orange blossoms spotted with black and tinged at the ends of the petals with reddish brown. Along with this also came examples of Neapolitan Cabbage and white Paris Cos Lettuces, two first-rate varieties which do not readily run to seed; and the Auvergne Pea, a prolific kind, easily distinguished by the curved form of its pods.
