In all the various departments of Art, there exists much diversity of opinion in regard to true excellence; scarcely any two acknowledged authorities agree in what is truly artistic and beautiful, and the further we recede from the true artist, the greater the disposition is to condemn.

The range of excellence in high Art is a very extensive one, and to take any particular school of Art for a standard, and judge all else by it, is a folly often committed by those of limited information. There is in no Art a law that overrules any peculiarity of style, manner of expression, or of execution; peculiarities exist in every individual, and the higher we ascend the scale of merit, the more original and less imitative both design and execution will become.

We have before stated the possibility of adorning a landscape in very many different manners, neither of which shall have any thing in common with each other, and yet all shall fulfil every condition of high Art, and strictly accord with the principles of refined taste. A diversity of talent in a collection of works of Art is much to be desired; a gallery of pictures by one artist, or of one school of art - a city built by one architect, or in one style of architecture, will not, and can not, satisfy the general taste for -variety. No matter how superior may be the taste and ability of the artist who designs and executes; by comparison, and not by repetition, the mind judges and appreciates, and forgets any sense of weariness. The employment of varied talent in any work of landscape embellishment, would be a somewhat novel feature, but would certainly yield far more satisfaction ,than the disposition to accept the whims of every would-be critic.

In Landscape treatment on an extended scale, such as public parks, rural cemteries, etc., and more particularly in our own Central Park, which is designed to be a model of landscape adornment, we should like to see a system of execution carried out, that shall furnish an example of the different styles of all the acknowledged talent and .ability that seek a name and fame in the pursuit of an Art so beautiful and attractive. We should prefer to see the execution of certain portions delegated to educated and skilful professors of the Art, and let them be alone responsible for its manncr of planting, creation of effects, and arrangement of details, and which shall join harmoniously with all around it. The intention is, as we understand it, to introduce the excellences that exist in all the various schools of landscape adornment; but as the tendency of any one controlling mind is to ran in a particular or peculiar direction, we shall see its impress in the execution of any and every mode that is adopted. To us the Central Park, like the Dusseldorf Gallery, is a school of study, and our wish would be to see displayed there all the talent in rural art and embellishment that money can command.

The duration of human lifo is not sufficient for any one artist to finish the Central Park, and each successive one, in order to show how much smarter and more efficient he is than his predecessor, will condemn and remodel all that he dare to of what has gone before him, and we may therefore hope to see carried out, simultaneously, individual styles of landscape art, as to look for their certain development at intervals of years.

" Insult not Nature with absurd expense, Nor spoil her simple charms by vain pretence; Weigh well the subject, be with cannon bold, Profuse of genius, not profuse of gold." - The Gardens.

As exponents of two schools of landscape treatment, and as examples showing the manner in which pure taste may differ, compare the primeval beauties of "Idle wild" nature left alone, with the princely park at "Wodenethe," its exquisite finish and elegance, a lawn that knows no equal, and an arboretum unsurpassed in every thing that is rare and choice, and say which indicates the absence of truly artistic management.

A certain intuitive knowledge of construction, or the instinct of self-preservation and protection, is a gift implanted in many grades of the animal kingdom; each species has one form of construction, they build after one plan, and the progress of time makes no change nor adds any improvement whatever; they adhere to the original designs, have no different orders of architecture, no modern forms, no Gothic, no Italian, no Elizabethan, and no new American style; and while instinct alone directs one course,.and one only, reason leads every man to adopt a different form from his neighbor, and to wage a war of criticism against all that does not fulfil the conditions that his experience, his imagination, or his supreme ignorance, has led him to believe to be correct.

We do not all see the same things through the same medium; impressions are not received alike; an acknowledged standard of taste is not a standard of taste to all men, and it is hardly reasonable to suppose there is a standard of education which will enable all men to think alike in matters of taste. The natural instinct of construction, and ignorance of all the progressive rules, established tastes, and collected excellences in that Art, and in the art of design, tempt men to become critics, and often to attempt the execution of works of art The education, experience, and skill of the artist, the architect, the civil engineer, the landscape gardener, the draughtsman, etc., are thoroughly ignored, the short cuts of professional ability are cast aside, and the preference acknowledged, to sink money in spoiling the beautiful hints that nature has generously given, rather than for that assistance or advice which would enable him to complete her admirable designs.

The sad disappointments often resulting from first attempts in landscape gardening, so little satisfaction for a liberal expenditure, and so much said about the cost of rural improvements, instead of experiments, are but few of the arguments we might use to him who expects to unite economy with taste in the embellishment of a country home, without first making himself master of the art he proposes to practice.

[Mr. Woodward's suggestion in regard to the Central Park is a novel one. We undoubtedly have talent here of a high order in landscape adornment, and an experiment of this kind would naturally tend to develop its highest phases. We- think it might be done in such a way as to harmonize all the parts into a beautiful and effective whole; but it would require a combination of the nicest judgment, taste, and skill. We must not, however, overlook the acknowledged advantages of having a master mind to preside over all great works. Mr. Woodward's suggestion evidently refers to that portion of the Park not yet laid out; but we fear that it comes too late to receive the serious attention of those having charge of the work. - Ed].
