PLANT ASHES. 
The value of plant a^h as a manure de|>enU>i 
chiefly in the amount of potash contained in it. 
Besides jwlash, plant ash freipiently contains 
appreciable quantities of phosphoric a<'itl, and 
sometimes larjje quantities of lime. The amount 
of potash and Hme vary between wide limits. The 
following exhibits the comitositiou of several
