flocks at home. The records should be kept for at least ten 

 days, and a full report given by each student in the class at 

 the end of the period. 



3. Trap nests. In order to determine which hens in the 

 home flock are laying, the trap nest may be used as part of 

 the practical work of this study. Students should install 

 trap nests at home. These nests^may be purchased at the 

 poultry supply house, or an ingen- 

 ious boy may make them. The 



manual training department of 

 the high school would find this 

 piece of work practical. The hens 

 .caught in the trap nests are num- 

 bered by leg bands. In selecting 

 eggs for breeding purposes, the 

 eggs laid by these trapped hens 

 are very desirable, especially if laid in the winter time. 



4. The egg. (a) For this exercise pupils should bring 

 to the class a few eggs for study and observation. As an 

 interesting introduction to the study the instructor may 

 tabulate on the board the following data for the collection 

 brought in:
