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, otlierwise they soon grow out of 

 all ordinary bounds, and become very unshapely. 

 Some of the bulbous-rooted kinds from tlie 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 sliining sand ; such as is to be 

 found on the surface of a moor or common, where 

 ^leaths naturally grow. They will grow pretty free- 

 ly in other kinds of soil, particularly in such as 

 iiave 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 M^hich, manure of any kind shoidd 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 lighter. 



Olives will do well in such, or in M'hat may be 

 termed a sandy loam, moderately rich ; to w^hich 

 unay be added a small quantity of lime or marf. 



Oranges, lemons, kc. like a strong In'own loam^
