40 THE ART AND PRACTICE OF LANDSCAPE GARDENING. 



should have 9 in. of soil on them, to obviate the danger of the 

 turf " scorching." All slopes and angles must be perfectly formed 

 to receive the turf. The turves should not be rolled over the 

 angles, but be laid to, and join, at them, so that a sharp arris' be 

 secured. On the site of any beds for flowers, or foliage plants, the 

 soil must be of proper quality and sufficient depth, and when de- 

 posited in solid ground should be drained. Grass is cut into turves 

 3 ft. long and i ft. wide ; they should be about i in. thick. 

 When such turves are rolled up, they will in autumnal and early 

 spring weather last for several weeks without permanent damage. 

 Before cutting turves, the grass should be mown, and then well 

 rolled. As they are relaid, all daisy, plantain, and bad grass roots 

 should be taken out. Care is required in cutting turves to regulate 

 the work so that the sections of grass may not be removed, or 

 accumulated, save as the site is prepared to receive them ; and the 

 surface made for them should have 6 in. of loam. When the 

 ground is to be sown instead of turfed, after the site is prepared, 

 let the sowing be made in springtime, and during showery weather. 

 A good mixture of seed for a lawn is that recommended by Mr. R. 

 Thompson, as follows (the kinds of grass are those suitable for 

 forming a good lawn, and the quantities of seed given are those 

 required for an acre) :
