PREFACE. 



Practical men— farmers, brewers, and maltsters — will, 

 I think, find in the pages of the book some hints which 

 may prove of value, as suggestive of the waste of 

 material constantly occurring in the granary, the 

 brewery, and the malthouse. 



Whilst divesting any sul)ject of the technicalities of 

 scientific language, I have endeavoured to be strictly 

 accurate as to facts, and the definitions of them. 



For the rest, Nature may speak for herself in her own 

 eloquent language, through her works and the marvels 

 of them.
