originals for electrotypes, and have at all times given the author 

 most courteous treatment. To the Macmillan Company, pub- 

 lishers of "The Citizen Bird," and the artist, L. A. Fuertes, the

 The three colored plates of birds and the colored plate of insects 

 were made under my direction. I am much indebted to the editor 

 for his painstaking effort in connection with this volume.
