Then men must never again talk of the "lines" of a ship! Perhaps Mr. Blomfield would accept a plumb line? One can hardly leave London an hour before a person who looks at the landscape may see the lines or boundaries between one mass and another. Who could stand amongst downs or an alpine valley and say there are no lines in them, inasmuch as one of the most visible and delightful things in all such cases is the beauty of those lines? This is the key of the whole question of landscape gardening. There is no good landscape gardening possible without a feeling for the natural gradation and forms of the earth.

It can be seen in little things, like the slope of a field as well as in the slope of a mountain, and it is the neglect of this which leaves us so little to boast of in landscape work. In a country slightly diversified it is, of course, more important than in a perfectly flat one, but in all diversified ground no good landscape work can be done without regarding the natural gradation of the earth, which will often tell us what to do. It is blindness to this principle which makes so many people cut their roads and walks crudely through banks, leaving straight sharp sides—false lines, in fact—when a little care and observation would have avoided this and given a true and beautiful line for a road or walk.

Once the necessary levels are settled and the garden walks by straight walls about the house are got away from, we soon come to ground which, whether we treat it rightly or not, will at once show whether the work done be landscape work or not. No plan, it seems to me, is so good as keeping to the natural form of the earth in all lawn, pleasure ground, and plantation work. Roads, paths, fences, plantations, and anything like wood will be all the better if we are guided by natural lines or forms, taking advantage of every difference of level and every little accident of the ground for our dividing lines and other beginnings or endings.

In the absence of any guidance of this sort, what we see is brutal cutting through banks, lines like railway embankments—without the justification there is for the sharpness of a railway embankment—and ugly banks to roads, very often ugly in their lines too. If we are ever to have a school of true landscape gardening, the study and observation of the true gradation of the earth must be its first task.
