of the department, length of the course, and age 

 and previous training of the students. If used 

 in connection with a short course of less than nine 

 weeks, it will be necessary to introduce the 

 exercises dealing with incubation at an earher 

 period in order to finish the work of brooding 

 before the end of the course. 



The exercises begin with the very elementary 

 work and touch only the practical side (the 

 work which each student should do and observe 

 for himself) and with which ■ every poultryman 

 should be very famihar. It is not designed to 

 take the place of a text, but to be used in con- 

 nection with and as a supplement to a thorough 

 modern text-book, the idea being to discuss the 

 various problems in such a manner that the 

 student can solve them by deductions from his 

 own observation and experience. 



If the institution is equipped with a depart- 

 ment of Zoology and Mechanic Arts, the work 

 in entomology and the repair and operation of 

 boilers and heatiag plants should be taken up in 

 their respective departments.
