SLOPING GARDENS I45 



require to be stepped, and this may be done in 

 many ways. Possibly the most economical 

 method is to fix wooden risers by nailing them 

 to stout pegs well driven into the soil at each 

 end, and to fill in the treads with gravel beaten 

 down and brought to a fair surface. Re- 

 taining boards should be fixed at the sides, 

 as shown in the illustration. 



Gardens in which the natural slope is trans- 

 verse to their length do not involve the same 

 difficulties, and they are not usually found of 

 such steep gradients,- or, if they are, their small 

 width, compared with their length, makes the 

 problem of planning a simpler one. It often 

 becomes feasible to effect a change of levels 

 at the path line in some such way as appears 

 in this sectional view.
