PREFACE 



It is not generally known that the farmer sometimes 

 receives but one-quarter of the retail price of milk (frequently 

 but 2 cents a quart),' and he can hardly be expected to 

 undertake a considerably increased expenditure for the

The aim of this book is to provide a working guide for 

 those pursuing or wishing to pursue one of the most whole-

 of clean milk.

 particular apparatus of certain manufacturers. But the
