 and average percentages in peat ashes drawn from various 

 sources: 1 



Minimum Maximum Average 



Potash .05 3.64 .89 



Soda 5.73 .83 



Lime . ... 4.72 58.38 24 



Magnesia 24.39 3.2 



Alumina .9 20.5 5,. 78 



Ferric oxid 73.33 18.7 



Sulfuric acid 37.4 7.5 



Chlorin 6.5 .6 



Phosphoric acid 6.29 2.56 



Sand .99 56.97 25.5 



Lime is nearly always found in peat ash, and like sand may at 

 times be present in considerable quantity. 



All the substances found in the ash of peat are likewise found 

 in that of sphagnum, as seen by the following analysis : 2 



Potash 17.2 



Soda 8.3 



Lime 11 . 8 



Magnesia 6.7 



Sulfuric acid 6.5 



Chlorin 6.2 



Phosphoric acid 6.7 



The following table gives the chemical composition of peat 

 from different localities.
