In the temperate latitudes of America and Europe, where the winters are long and severe, evergreen trees are objects of particular interest. At this we need not be surprized, neither is the cause difficult to be divined. When wrapped in the midst of winter - having perhaps weeks of cold or snowy weather, the snow covering everything as far as the eye can reach, with nothing to relieve it, the trees denuded of their foliage, and all vegetation not asleep only, but apparently annihilated - if we peep through our windows we behold nothing save a perpetual, monotonous sheet of snow, the eye soon becomes wearied, and we instinctively turn away to seek a little repose. But how changed would all this appear had the eye alighted on a few graceful Norway spruce, their branches loaded with singularly beautiful cones; or some majestic hemlock spruce, etc. Evergreens such as these would lend a charm to the scene. Ladies and invalids, however confined by weather, may gaze with the most intense delight on objects such as these - the most beautiful and graceful of nature's works.

If we walk abroad in this wintry season, what a contrast is afforded from the bleak, desolate dreariness of deciduous trees to the rich and beautiful foliage of masses of evergreens now in full dress, "decked in all their beauty".

Persons acquainted with the well kept gardens of England, know well what a beautiful effect evergreens have in the midst of winter, say the dreary month of January. If the weather is mild at this season - and it is not often severe - the many varieties of Lauruslinus will be a sheet of bloom; many of the early varieties of Rho-dodendrons will be in flower, such as R. pulcherrima, daurica, etc. - the former I have seen fully in bloom, in the open border, the first week in January. Some of the species and varieties of Arbutus will be now in bloom - A. procera and hybrida about their height, the varieties of A. unedo passing off. Hollies in their various varieties are loaded with berries of the most brilliant crimson scarlet; their rich and varied foliage give a marked and distinct feature to a collection of evergreens. Many have large foliage of the deepest green color, others large foliage margined with the richest gold, and every imaginable intermediate shade. At this time such evergreens as English laurel, Portugal laurel, yews of sorts, arbutus, evergreen oaks, with the whole collection of conifers, are perfection as regards their foliage.

At this season, also, many deciduous shrubs are in bloom, such as Chimonenthus fragrans, C. grandiflo-rue, C. luteus, Jasminum nudiflorum, Daphne mezereon, Erica cornea and others, Cydonia Japonica and varieties, with many other interesting and beautiful shrubs. Among herbaceous and bulbous-rooted plants, many lovely genera are now in flower. With abundance of such materials at command, we need not be surprized if the man of taste should so arrange and dispose of them as to make the flower garden present in the midst of winter an interest and beauty peculiar to itself at this dull season. So well is this understood, that the appearance of the winter garden is as great a consideration, and in many places greater, than its summer appearance.

* That we hare many Intelligent and excellent practical gardeners in this country, no one can doubt, (Mr. Chorlton himself is a good example,) but somehow as yet the pursuit has not attracted many native born Americana, not even the sons of gardeners. It is not yet suffciently elevated and well paid as a general thing. The great majority of those who come here from abroad and palm themselves off as gardeners, were nothing more than mere garden laborers in their own country, and convey an unfavorable impression of the craft, sure enough. However, they are good enough for places where the gardener is required to do all sorts of work, or in other words, to "make himself generally useful" - ED.

The climate of Great Britain is particularly favorable to this system of gardening. Laying with its isles off the west coast of Europe, it has the heat of Bummer as well as the winter's cold very much modified by the vast waters of the Atlantic If we glance at all the broad-leaved evergreens as they are to be seen in that country, we should say they are luxuriating in a climate that is to them perfection - very intense cold they are incapable of withstanding, and intense heat with a brilliant burning sun is not over agreeable to many of them, the latter probably caused by the immense draw on their broad foliage in heated, arid weather. Among the other offices which leaves perform is that of respiration, and if the plants are constituted for an atmosphere more cool and humid than our own, it follows that the immense draw on the foliage must injure if not destroy the plants. The size of the foliage is no criterion by which to judge the degrees of heat or cold which a plant will bear. Our native Magnolia grandiflora, coming from a southern clime, will stand any amount of heat and brilliant sun which would be destructive to plants of more temperate, humid climes, or whose natural habitat is the shade of forests.

The continent of Europe is not so favorable to the growth of such evergreens as Great Britain. Like our own country, the cold of winter in the northern parts, and the heat of summer in the more southern, appear to operate alike injuriously. This latter remark will hold good of only some of the genera, as many grow with as great vigor and luxuriance, and even greater in the southern countries of Europe, than in England. Among these may be numbered Arbutus unedo, Lauris noblis, Viburnum tinus, etc., etc.

In this country it will perhaps be said this description of gardening cannot be carried to as high a state as in England, more particularly in the Middle and Northern States, from the length and severity of our winters; yet by collecting together the materials now at hand, or which may be easily procured, much more may be accomplished than is generally imagined in this way. If we pause for a moment, and consider which are the countries we can with most certainty draw our supply from, I think without much hesitation we shall decide on many pails of Asia as likely to give us many plants and trees suitable to our purpose. The extensive empire of China furnishes many. The climate of that country approximates more closely to our own than any other - the middle and northern parts to our Middle and Northern States. The rivers about Pekin are as hard frozen in winter as our Hudson, and the summers as bright and warm. The southern parts may in some degree be compared to our Southern States. Now why should not plants from that country be perfectly at home in this ? And we find they are.
