WALKS. The place for a Walk is where it is needed. It should go directly between two points. It need not be straight, but if it is curved, the curve should be direct. That is, the pedestrian should be conscious that he is going in the direction in which he desires to go, and is not making a detour for the simple purpose of following the walk. Convenience should be the first thing to be considered. After the Walks have been laid in the most convenient places, the question of ornamenting the borders may be considered. It is always well to avoid, so far as possible, the bisecting of lawns by Walks, as that makes two lawns where there should be only one. The larger a greensward can be made to look, the more park-like and natural is the place. Avoid taking the Walks circuitously around the borders unless they are laid for the simple purpose of making a ramble to show off the grounds. All Walks which are designed for serious use should appear to be necessary, direct and convenient.
Some soils which contain considerable loam and sand will pack with tramping and will make good Walks, but it is usually necessary to lay some material on the soil. Gravel, cinders, and the like, may be better than the natural surface; but in many cases they are worse, since the surface is loose and is unpleasant to walk on. In Walks which are on decided slopes, and down which the water is likely to run, any loose material is very objectionable, since it runs to the low places. The best material for Walks, all things considered, is cement, or what is called artificial stone. If well made, it is as durable as flagging, and is not so likely to get out of place. It holds its surface perfectly year after year.
The only objection to cement Walks is when they are more or less temporary, for in such cases they cannot be moved. There is often very serious difficulty in securing good cement Walks, but the difficulties are easily overcome. They are chiefly two: there is not sufficient draining material beneath the cement; and the cement itself is not made strong enough. There should be at least a foot of loose material, as brickbats or cinders, below the cement cover; and if the place is low and likely to hold water, there should be still greater drainage. Pound the material down, or let it stand for some time until it becomes thoroughly settled together. Then lay the cement in two courses. The first course may be three or four inches thick and made of well mixed mortar, comprising three parts Portland cement, one part water lime, and two to three times as much sharp sand as Portland. When this has become partially hardened, but before it is set and while still moist, put on a finishing layer of one inch, made of one part Portland cement, one part water lime, and one part sharp sand. It is important that the materials be very thoroughly mixed. See that the edges of the walk are made square and true by laying down a form of boards lengthwise the area before the cement is put on. The edges should be as thick as the middle, for a thin crust on the edge tends to snap off. A walk made in this way on a well-drained foundation will last almost indefinitely. It is best that it be made in such season that it can become thoroughly set before frosty weather comes.
