THE AMERICAN MUSEUM JOURNAL 
THE AMERICAN MusrumM JOURNAL is a magazine -issued primarily 
to keep members in touch with the activities of the Museum as depicted 
by pen and camera; also to furnish Members with reliable information 
of the most recent developments in the field of natural science. It 
takes the reader into every part of the world with great explorers; it 
contains authoritative and popular articles by men who are actually 
doing the work of exploration and research, and articles of current inter- 
est by men who are distinguished among scientists of the day. It takes 
the reader behind the scenes in the Museum to see sculptors and prepara- 
tors modeling some jungle beast or creating a panorama of animal life. 
It shows how the results of these discoveries and labors are presented 
to the million public school children through the Museum Extension 
System. Published monthly from October to May. Terms one dollar 
and a half per year.
