INTRODUCTION. 



The scoring and judging of the dairy cow is rapidly becoming 

 popular as a practicum in the teaching of agriculture in secondary 

 schools. The work has done much to arouse interest in animal hus- 

 bandry and dairying. A need has been felt for specific directions as 

 an aid toward making this work more practical, and it is the aim of 

 this bulletin to help fill this want. 



CLASSROOM DISCUSSION. 



Use of illustrative material. — When conditions approach the ideal 

 the greater part of stock judging is learned with the animals to be 

 judged present (fig. 1). As a matter of convenience preliminary 

 ]e.s.sons are usually given in the classroom. The teacher should bear 

 in mind, however, that the student learns largely through what he 

 sees, and should make use of an abundnnce of illustrative materiivl. 

 Before proceeding with a study of the dairy type the student should 

 learn the names of the parts of a cow. It is not safe to assume that 

 the high-sfhool student knows all the terms used in judging. A 

 diagram siirji ns given in figure 2 is useful in sliowing the ideal dairy 

 type as well as in giving the names of parts. This outline may be 

 mnde into a chart or copied upon the blackboard. If drawn upon 

 the board the names of the jiarts may b<i erased and the students
