Tliis waste product consists, in the main, of carbonate of 

 lime. Its agricultural value as a lime compound is somewhat 

 increased by the access of phosphoric acid, which may be 

 valued from nine to ten cents per hundred-weight. Its per- 

 centage of potash is scarcely more than many varieties of 

 limestone contain.
