These are the various soils and substances 

 which Nature presents to the horticulturalist, and 

 of which, and other substances, he compounds 

 his composts, according to their nature and capa-

 different plants require different descriptions of 

 soil is an universally acknowledged fact. When 

 a plant is first taken into cultivation, the culti- 

 vator generally takes a lesson from Nature, parti- 

 cularly as to the kind and qualities of the soil of 

 the native habitat ; rightly judging that his 

 artificial compost shoald be similar, in order to 

 expect and secure success in the management. 

 And though an exact resemblance in constitu- 

 tion and quality would be sufficient for the mere 

 existence and ordinary growth of the plant so 

 translocated, yet the florist is not merely content 

 with its existence : he will study to pamper it
