 practicable? How does the ideal vary with different classes of 

 stock? How are animals judged in regard to their excellence? 

 What is meant by the judging or the scoring of animals (481o)? 

 If possible, apply the score cards on pages 276 and 277 to animals 

 for which they are intended. What is the first practice in breed- 

 ing for an ideal? What is the second point? What is meant by 

 a "prepotent" animal? Give some of the common characteristics 

 of a prepotent animal. What is a "sport"? What importance do 

 these sports usually have in the improvement of the race? What

 pedigree? What are the advantages of a pedigree (486, 486a)? 

 What is meant by pure-blooded stock? Is pure stock always to

 prairie countries? How much on farms in the East? What are 

 the two theories or principles controlling the quantity of stock a 

 farm can keep with profit? Explain the practice of buying stock

 stock-feeding likely to be profitable? What is one reason for the 

 growth of this practice (499)? What is the value of stock- feeding
