After becoming well acquainted with grouping, we should bring ourselves to regard those principles which govern our improvements as a whole. We therefore must call the attention of the improver to the two following principles, which are to be constantly in view: the production of a whole, and the proper connexion of the parts.
Any person who will take the trouble to reflect for a moment on the great diversity of surface, change of position, aspects, views, etc., in different country residences, will at once perceive how difficult, or, indeed, how impossible it is, to lay down any fixed or exact rules for arranging plantations in the modern style. What would be precisely adapted to a hilly rolling park, would often be found entirely unfit for adoption in a smooth, level surface, and the contrary. Indeed, the chief beauty of the modern style is the variety produced by following a few leading principles, and applying them to different and varied localities; unlike the geometric style, which proceeded to level, and arrange, and erect its avenues and squares, alike in every situation, with all the precision and certainty of mathematical demonstration.
