IMPORTANCE OF THE DAIRY INDUSTRY 11 



8. Why is more cheese used in Europe than in America? Why 

 are v, r e using more cheese than formerly ? 



9. Of what dairy products does the United States import more 

 than it exports? Of which does it export more than it imports? 

 Whi<-'.h are greater in value, the total imports or exports? To what 

 proc act is this due? See page 296. 



COLLATERAL READING 



The Production and Consumption of Dairy Products, U. S. 

 Dei t. Agr., Bulletin 177. 



Tde Use of Milk as Food, U. S. Dept. Agr., Farmers' Bulletin 363. 



1 1 the lists of collateral reading no attempt is made to give a 

 complete list of books and bulletins. A few of the more important 

 references that are readily available are given. Bulletins of the 

 diff< rent state experiment stations are not always available, for this 

 reason they are not often given as collateral reading but are referred 

 to in footnotes. At the beginning of the course the experiment 

 stat ion in your state should be asked for all available bulletins. If 

 af tt r examination it appears that certain ones of the publications 

 are likely to be needed for special study, members of the class should 

 sen< I postal cards requesting them. It is better to have the students 

 do 1 his writing because instruction as to where to get information is 

 a part of the course. 



Write to the Bureau of the Census, Washington, D.C., or to your 

 congressman for the census report on agriculture for your state. 

 Also ask for the report on animals and animal products for the 

 United States. 



Many important laboratory exercises are given after Chapter 2, 

 page 39, and for following chapters. These exercises should be 

 begun while Chapters 1 and 2 are being studied. Because of the 

 frequent use that is made of the Babcock milk test it is a good plan 

 to begin the laboratory work with Exercise 20, page 196.
