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.
