LABORATORY INSTRUCTIONS 



1. Since the exercises are outlined to occupy a definite period of time 

 and since the laboratory periods are distinctly designated, it is important 

 that the student be in his place ready to carry on the work at the ap- 

 pointed time. 



2. Every student will be held responsible for unnecessary breakage or 

 loss of apparatus. 



3. A schedule will be found posted in the laboratory stating the groups 

 of students who will perform certain exercises during each period when a 

 division of the class is desirable, especially on account of a large amount of 

 work to be accomplished. 



4. Exercises which are continuous, over a number of periods, should be 

 distinctly labeled and care taken that apparatus is not disturbed between 

 periods. Many exercises such as chore work, incubation, brooding, etc., 

 require some daily attention. This must be given as required and credit for 

 time so spent should be given. 



5. The results of all exercises and experiments must be written up 

 promptly after each laboratory period. 



6. Read over each exercise carefully before beginning the work and be 

 sure that the text is thoroughly familiar. Failure to appreciate the object 

 and mode of procedure is very apt to mean failure in the work. 



7. All answers to questions and all notations should be made clear, neat 

 and concise. The report of each exercise should be written up by itself and 

 the conclusions neatly and carefully arranged. 



8. All exercises should be carried on as outlined, as quietly as is possible, 

 with accuracy, and with a complete understanding of the work. When the 

 work is complete each student or group of students is responsible for the 

 cleaning and replacing of all apparatus used. 



9. Access to poultry texts, which can be used as reference work in con- 

 nection with these laboratory exercises, will be found very useful. Such a 

 reference list follows:
