r fhis table shows us that the Mangolds require the min- 

 eral ingredients of manure in the following order, when ar- 

 ranged with reference to their importance : — Potash, Soda, 

 Chlorine, Lime, Phosphoric Acid, Magnesia, Sulphuric Acid, 

 Silica. In addition to these minerals other substances enter 

 into the composition of Mangolds, the most important of 

 which is Nitrogen. Barn-yard manure contains a*bout all the 

 elements needed by vegetation, but not always in the right 

 proportion, therefore, when applying it, it is always profita- 

 ble to know the proportions of the minerals which enter into 

 crops that the deficiency may be supplied from other sou; 

 It is perhaps hardly necessary to say that unleached wood
