PREFACE 
Tuts book shows why some milk contains 
millions of bacteria and how they get into it, 
and how easy it is to keep them out. It shows 
that the millionaire with his fancy barn has no 
monopoly on cleanliness, but that any farmer 
can produce milk which is just as clean as cer- 
tified milk. It shows that the man himself is 
far more important than the dairy score card, 
and that hundreds of farmers in many dairy dis- 
tricts are now making a business success of pro- 
ducing clean milk.
