The book of garden management : Comprising information on laying out and planting Gardening -- Great Britain. depressions m the ground left, which the corvect basis thus provided furnishes, the necessary data for the exact level which can be maintained by the soil on the spot can be correctly estimated. The trenches themselves can then be •elevated or depressed at pleasure, supposing the right level not to be known when they were formed. When this plan is adopted, the dotted line AB would represent the trench formed, and the dotted vertical lines the levelling- stakes. Grounds with a regular slope in any one direction are managed in a similar manner. Suppose the section that follows is to have a fall of 20 inches in 200 feet, proceed thus : Level the distance ah; look along the line to c ; make the stake c level with ah ; measure down 20 inches to d, and the line ff would form the top of the stakes. Then measure down from the top of each stake^ tlae distance fi-om e to E, and this would give the required level or even surface, EF. However, to make a line of this length, with 20 inches fall, and the levelling-stakes 10 feet apart, a piece of wood, 1 inch thick, must be placed on the top of each stake as you proceed. For instance, the level would rest on the top of the stake at c, but the inch would be inserted under the end at Z>; it would then rest at h, and the inch be moved on to the next, and so on throughout the entire line. The amount of fall in any given length being given, and the distance between the stakes ascertained, the thickness of the props used will at once be determined. But ground with an even fall is per- haps most expeditiously levelled by the aid of three borrowing-pins, as they ;are termed: they are simply upright splines of wood, say _ 2 or 3 inches wide and 1 inch thick, with a cross-piece of the same or greater dimensions, and from 3 to 5 feet long. White is perhaps as good a colour as any, with a black line across the centr
