I pass on to remark upon a fifth error. One gentleman will, from motives of economy, _stick in the plants with as little labour as possible_: another will aim at the same result, by putting in fewer, or smaller plants than he ought to do. Both these, and indeed all the parties, who are influenced by the same narrow and shortsighted views, greatly err: these are not the _cheapest_, but the _most expensive_, as well as the worst adapted, modes of planting. To insure a healthy and vigorous _commencement_ to a Plantation, if that is followed up by suitable treatment afterwards, is to secure both rapid progress, and early maturity, and by necessary consequence, the largest possible amount of pecuniary return. Lastly, as to modes of planting, and without ranging either party among those who are clearly and decidedly _mistaken_ in their views, one class of persons will plant _thickly_, and another class will plant _thinly_, from various motives, but both without paying due regard to the capabilities, and adaptation of the soil, and, as is very natural, in the absence of all calculation, both are frequently subjected to the same result,—either a partial or complete failure of their expectations. It is neither my purpose, nor is it in my power, to decide, upon paper, what is the best average distance at which the trees of a young Plantation should be placed from each other. Many questions ought to be previously asked, as many very important considerations will present themselves to the mind of a practical man, before he will decide. In the average of cases, where _planting for profit_ is the object, the question is not one of much practical difficulty; but in many others, the primary purpose, or the ultimate aim, of the planter—the local market—the cost of plants, &c. will claim very special attention. When the object is to beautify the Landscape, or to produce effect in the immediate vicinity of a Mansion, it will be necessary to set aside ordinary rules, and to depart from _some_ of the recognized principles which ought always to govern, in planting for profit. But even here, nothing should be done, nothing should be attempted, which is not in strict consistence with those general laws which the principles of vegetable physiology impose, alike on a Gentleman who removes a large tree upon the plan recommended by Sir Henry Steuart, and on the practical Planter, who is professionally employed to plant a large tract of country.
