96 LANDSCAPE GARDENING. 



Care should be taken that no basins be formed by the 

 walks or drives as they pass through the valleys or turn 

 along the face of a slope, and if such become a necessity 

 culverts of stone or tile should be put under them so that 

 the water may pass to the other side before there is much 

 accumulation. 



The edges of the walks and drives will need more or less 

 attention at all times to keep the grass from growing in and 

 forming irregular borders, and trimming is best done with 

 the " edging knife." The surface also will need an occa- 

 sional raking or smoothing over, and once in two or three 

 years a dressing of screened fine gravel or sand will greatly 

 improve the surface and keep it filled up to the level of the 

 lawn. 



If the workmen employed cannot cut the edges to true 

 curves by the eye, the garden-line should be stretched and 

 stakes set at frequent intervals along the curve until a 

 complete and perfect curve is outlined. 



All weeds should be removed before they become so fully 

 rooted as to require the hoe or hook to remove them. 



On the drives all loose stones or those projecting above 

 the surface should be removed at once, for, besides the 

 discomfort they cause the traveller, they are seriously 

 injurious to botli the carriage and the road.
