In ornamental culture we would recommend precisely the same principles, and here indeed it is, if possible, more important than in fruit culture, inasmuch as the objects grown are more varied, and involve a greater variety of detail in their management.

It is a great mistake which many people seem to labor under, that to have a fine garden they must needs have a great variety of plants. We admit that variety is a desirable feature in the embellishment of a garden: but there can be. and there are fine gardens without a great variety. The largest collections of trees and plants fail to yield any satisfaction, unless they are well arranged, and in the most perfect health and vigor. But it is scarcely possible for persons who hare just turned their attention to gardening for the first time in their lives, and who endeavor to dispense with the aid of a professional gardener, to arrange and cultivate a great variety of plants with any satisfactory degree of success. When they do attempt such an undertaking, as they very often do, unfortunately, their first year's experience is a sad chapter of failures and misfortunes. Their seeds fail to grow; their trees and shrubs die; nothing goes right; and the seedsman and nurseryman are charged not only with their own delinquencies, which are generally numerous enough, but they have to bear the whole blame.

Bad management or unfavorable seasons are not taken into account, because the effects of neither one or the other are understood or appreciated.

We therefore urge upon beginners the propriety of exercising great caution in making their first selections. Every tree, shrub, and plant, should be perfectly hardy, and of the easiest cultivation. New and rare trees and plants are generally those most noticed in the periodicals, and beginners are too apt to think they must have these; but in this they are wrong. Inquire not for novelties, but for old and well-tried species and varieties that have been proved to succeed everywhere and with even indifferent treatment These are what you need; and when you have attained complete success with them, and have become somewhat familiar with the nature of the different tribes of plants, and with the principles as well as details of culture, you may safely enlarge your collection.

Among the plants used in the decoration of gardens, there are a great many genera, species, and varieties; all of which require a special culture and treatment, and without which they will not succeed. For instance, among the popular families of garden plants, we have Roses of many distinct classes, Carnations, Phloxes, Paeonies, Hyacinths, Tulips, Lilies, and a multitude of other plants considered indispensable to a good garden. Now, if a beginner will at his first essay procure a collection of all these, nothing can be more certain than his failure and disappointment Far better that he should commence with only one; and we will say Roses, for an example. But among Roses we have many classes, each requiring a treatment of its own; and in every class there are varieties known as vigorous growers, free bloomers, and of easy management in genera], while others are notoriously uncertain. Now the beginner should confine himself entirely to such as are least difficult to manage. A fine display can be made with even two or three sorts of Roses grown in perfection.

From among the classes known as summer Roses, including Hybrid China, Provence, Moss, etc., certain varieties may be selected that grow as freely as Willows, and that no one could fail with who would give them good soil, and cultivate them as well as they would a hill of potatoes. So among the popular class called Remontants, or Hybrid Perpetu-ak, there are vigorous growers, such as La Reine, Baron Prevost, etc, that may always be relied upon. We would plant entire beds of these reliable sorts, and have a magnificent show, rather than select a great variety, and have a rose-bed resemble a those in which a small number of plants or families of plants are well grown. Few amateurs become famous as cultivators, either in this or any other country, except those who confine their attention to a small number of objects. In Europe, we hear of one man famous for his Roses, another for his Pelargoniums, another for his Pan. sies, another for Tulips, etc., and people will travel hundreds of miles to witness the perfection to which each of these has attained in his special department. It is thus that all classes of plants have been improved and brought to their present state of perfection.

Until amateurs in this country direct their attention more in this way to the culture of special objects, we shall not see very great improvement in any particular department, nor will we have many novel varieties of home origin. Professional cultivators, as well as amateurs, with us, aim generally at too much to do it well, or as it should be done. A nurseryman or florist of small means would, we think, do much better by confining his attention to some special culture, and make himself famous in it, rather than to dabble in all, and do none properly. In France there are Rose-growers who devote their whole attention to Roses; and purchasers in every part of the world look to them for supplies. Very large establishments only can with advantage embrace a general culture, because they can make each department a special one, and manage it as if it were a separate concern.

Gardening with us is but in its infancy. Every year thousands of persons are turning their attention to it for the first time, and without any guide or preparation. It is not surprising, therefore, that great errors are committed, and losses sustained. We think we have touched upon one of the most prevalent errors; and we would be glad to have a chapter on the subject from some of our amateur correspondents, who can write feelingly from experience. The season for bedding out summer-flowering plants in masses, according to the prevailing fashion of modern gardening, is at hand, and the suggestions we now offer may be entitled to some consideration in directing the choice of plants. Those who have little time to devote to the garden, will always find their pleasure and profit promoted by choosing not a great variety, but such things as are easily managed.
