may be termed neither stiff nor light, and mode- 

 rately rich. But there being many varieties in this 

 genus of plants, the soils for them should be consi- 

 derably varied in quality. The rank growing kinds, 

 should be kept in poorer earth than those of more 

 humble growth, otherwise they soon grow out of 

 all ordinary bounds, and become very unshapely. 

 Some of the bulbous-rooted kinds from the Cape of 

 Good Hope, are more impatient of moisture than 

 others, and should therefore be put into a more fri- 

 able soil. 



Heaths like a moor earth best, in which is a large 

 proportion of clear shining sand ; such as is to be 

 found on the surface of a moor or common, where 

 heaths naturally grow. They will grow pretty free- 

 ly in other kinds of soil, particularly in such as 

 have a large proportion of vegetable mould inter- 

 mixed, but they will not flower in perfection in 

 other than native moor earth, as above defined ; 

 to which manure of any kind should not be ap- 

 plied. 



Myrtles like best a loam of a middling texture, 

 fresh, but not enriched with dung ; otherwise they 

 are apt to grow out of bounds, as observed above of 

 geraniums. The double flowering kind, however, 

 and the orange-leaved, require a soil somewhat 

 richer and lighten 



Olives will do well in such, or in what may be 

 termed a sandy loam, moderately rich ; to which 

 may be added a small quantity of lime or marl. 



Oranges, lemons, &c, like a strong brown loan?.
