1508. In planting in the geometric style, the first consideration is the nature of the whole or general design; and here, as in the ground, geometric forms will still prevail, and, while the masses reflect forms from the house, or represent squares, triangles, or trapeziums, the more minute parts, characterised by lines rather than forms, such as avenues, rows, clumps, and stars, &c., are contained in parallelograms, squares, or circles. In regard to the parts, masses and avenues should extend from the house in all directions, so far as to diffuse around the character of design; and as much farther in particular directions as the nature of the surface admits of, the distant beauties suggest, and the character of the mansion requires. In disposing these masses, whether on a flat or an irregular surface, regard must be had to leave uncovered such a quantity of lawn or turf as shall, at all events, admit a free circulation of air, give breadth of light, and display the forms of the large masses of wood. Uniformity and variety, as a whole, and use as well as beauty in the parts, must be kept constantly in view. Avenues, alleys, and vistas, should serve as much as possible as roads, walks, lines of fences, or screens of shelter or shade; but where this is not the case, they should point to some distant beauties, or near artificial objects, to be seen at or beyond their termination. The outer extremities of artificial plantations may either join natural woods, other artificial scenes, cultivated lands, or barren heaths or commons.
