shrubs is a long one, but there should in every 

 case be a goodly number of dwarf conifers of the 

 Savin class, such as Juniperus compressus nanus and 

 the ordinary J. Sabina. Very choice, delicate plants 

 should be grown in a portion of the garden specially 

 allotted to them, in order to avoid risk of their 

 becoming overwhelmed and lost. Very many of the 

 choicest species succeed best in the moraine. It is 

 a common but misguided practice to plant yuccas in 

 the rock gardens. No plants are more hopelessly out 

 of keeping with the general character. These and 

 any plant or shrub which has anything of a tropical 

 aspect miist be rigidly excluded. 



No difficulty should be experienced in respect of the situation of the rock garden, 

 for there are numberless species to suit every aspect. The shade, and even the 

 proximity, of trees must 

 be carefully avoided. 

 Generally speaking, the 

 more open and exposed the 

 situation the better, pro- 

 vided some sort of shelter 

 can be furnished against 

 cutting or excessively bois- 

 terous winds. In every 

 case the rock garden should 

 be as far as possible from 

 the dwelling-house, and the 

 transition to it should be 

 gradual. It is a great 

 mistake to cramp the rock 

 garden unless the space 

 available is very circum- 

 scribed, for the greater the 

 freedom the greater will be 

 the illusion of reality. Fur- 

 thermore, nearly all alpines 

 love light and air. 



There are various 

 forms of rock garden, such 

 as the dell, the ravine, the 

 miniature cliff, the knoll. 

 Many different types will be 

 found in the illustrations. 

 Even in the smallest back- 

 yard there is scope for a 

 square yard or two of such 

 construction as is seen in 

 Figs. 359, 360 and 363.
