This material consists mainly of the skins of corn ; it is evidently 



the insoluble residual matter left behind after the conversion of the 



starch into glucose syrup. The manurial value of the article rests 



mainly on the amount of nitrogen it contains in form of insoluble 



nitrogenous matter. To render it an efficient manure requires in the 



majority of cases a liberal addition of phosphoric acid and potash.
