TABLE OF SOILS. 



The following compounds of soils are adapted to the nature of the 

 Plants contained in this work: — 



REMARKS ON THE NATURE OF SOILS USED IN THE ABOVE TABLE. 



Peat or Savanna soil is of a dark color, with a large portion of white 

 sand incorporated with it, and is found frequently in New Jersey. A 

 mixture of two-thirds black earth from the woods and one-third of 

 pure white sand will be similar to it, and may be used as a substitute, 

 but it is not exactly of the same nature. 



Loam is of a light-brown color, and is that from the top of old pas- 

 tures or commons, which should lie one year, and be frequently 

 turned before using. It ought not to be from a clay bottom, and 

 merely three inches of the turf taken. 



Leaf mould is that which is to be found on the surface of the ground 

 in woods, and is the decomposed leaves. It may be termed nearly 

 of first rate importance in vegetation. 



Sand is a substance that is generally known, and that which is found 

 on the surface is decidedly the best. If it is from a pit, it must be 

 spread out and frequently turned, that it may assimilate with the 

 atmosphere before using; four months will be sufficient. 



Manure.hehre using, must be decomposed to very fine particles. It 

 will require two years, during which time it must be often turned, 

 and the longer it lays it will be the finer and more congenial.
