APPENDIX I 



The questions given at the end of each story are designed to draw out 

 ihe pupil's power of observation. The teacher will readily supplement 

 these with other questions that will suggest themselves. 



The detailed descriptions which follow, together with the range of the 

 chief birds, will assist pupils and teachers in a more technical study ot 

 these and other birds. 



In making these descriptions the following abbreviations are used: 

 L. represents length; W., wing; T., tail; M., male; Fe., female. 



The length of a bird is determined by placing the specimen upon its 

 back on a smooth surface and measuring from the tip of the bill to the 

 end of the tail. The length of the wing is the distance from the joint 

 nearest the end to the point of the longest wing feather. The measure- 

 ments are given in inches and hundredths.
