THE CHARM OF THE WATER-FALL 



ing water so attractive as. that which is made to rush 

 over rough rocks. 



When the garden has not sufficient slope to make 

 the water-fall plausible (and it is never attractive 

 unless there is an excuse for its existence) a terrace 

 slope readily may be arranged by grading at the 

 point of the natural water supply. Lacking this sup- 

 ply, it may be found that the artificial introduction 

 of water will prove even more satisfactory from the 

 decorative side of the question, as it can then be 

 installed at the particular point where it will be most 

 effective in the general design. On the terrace of 

 made ground it is unwise to depend upon clay pud- 

 dling or other insecure form of building the channel 

 that is to conduct the water to the lower spaces. 

 Instead of steps formed merely of rough stones set 

 firmly in clay, build the channel of concrete', with con- 

 crete steps where the water-fall is to be formed. 

 Then an arrangement of stones on these steps will 

 break the flow of the water, and cause the dash and 

 foam that are so desirable. 



When necessary to build a dam for the big garden 

 lake greater problems confront the amateur, and it 

 may be found that the advice of an expert engineer 

 will be required. Among the famous water gardens 

 of California the dams for water-falls are constructed 

 of concrete in keeping with the concrete finish of the
