be an excuse for hasty workmanship. 

 There is a use to which rockwork is 

 seldom put, namely, as a boundary wall. 

 It is true considerable trouble and ex- 

 pense are entailed, because such a wall 

 must ordinarily be double, with at least 

 two feet of good soil between the faces. 

 The second face should be of rock or 

 brick or concrete, according • as it is or is 

 not visible from the garden. The method 

 of construction is illustrated in Fig. 375, 

 and examples are to be seen in Figs. 366, 

 373 and 374. A perforated pipe led 

 along the top of the wall will make it 

 a suitable home for the choicest subjects. 

 Failing that expedient, the soil should 

 consist largely of peat, sand and leaf- 

 mould, with but a small proportion of 

 loam. Water properly employed forms 

 a charming feature in any rock garden. 

 Few things are more delightful than the 

 reflection in still water of overhanging 

 rocks clothed with masses of blossom. A 

 good example may be seen in Fig. 377.
