SOIL. 



In potting window plants rich soil should generally be 

 used. The different kinds of soil are, 



Peat, which is black earth or decomposed vegetable 

 fibre, usually taken from meadows or damp woods. If a 

 mixture of white sand is with it, it becomes more valuable. 



Loam, our common garden soil. It may be black or 

 light brown. The best is obtained by taking the turf of 

 old pastures and letting it lay till it all crumbles. 



Sand, common, or " silver," such as used by glass 

 makers. It should be free from salt. White beach sand 

 may be freshened by frequent washings. 



Leaf mould, the decomposed leaves, being the top soil in 

 old woods.
