Changes in Planting.-Straight Lines.-Quincunx.-Let us now trace the progress of change in the fashions of planting; by which I mean the various systems adopted at different periods for making trees artificial ornaments. The first was, doubtless, that of planting them in a single row at equal distances, which prevailed in the garden mentioned by Pliny. The next step was that of doubling these straight rows, to form shady walks, or, adding more rows, to make so many parallel lines. But fashion, not content with the simplicity of such avenues of trees placed opposite to each other, invented the quincunx, by which these straight lines were multiplied in three different directions. As the eagerness for adopting this fashion could not always wait the tedious growth of trees, where old woods existed, they were cut through in straight lines and vistas, and in the forms of stars and pates d'oies which prevailed at the beginning of the last century.
