THE ROCKERY. 2? 



stones, wherever suitable ; but, at the same time, it 

 is necessary not to interfere with the plants, or the 

 situations they are to occupy. 



It is further desirable, that around part of the 

 rock-work (at the base) a border should be formed. 

 Should your locality permit, perhaps the south-west 

 side may be as desirable as any. This border should 

 be made up with peat, containing abundance of 

 white sand and small white stones, for some of the 

 Erica tribe, Azalea procumbens, Arbutus alpina, 

 &c. These thrive most luxuriantly in this kind of 

 soil. We have observed them half way up Bennevis, 

 and found there specimens of the latter plant in 

 full fructification. Another portion of this border 

 should be composed of sea-sand and gravel, with the 

 addition of some peat well incorporated, for such as 

 Lithospermum maritimum, Glaux maritima, &c., 

 which are not by any means easily preserved, or 

 cultivated in any other soil. Some large and curious 

 stones may be placed here and there along the border.
