FOREWORD 
Life in an Ant Hill is the thirteenth of thirty 
booklets in the Elementary Science Series. 
It was prepared by the Philadelphia Unit of the 
Pennsylvania Writers' Project, sponsored by 
the Pennsylvania Department of Public Instruc¬ 
tion. 
This booklet, written by Mark Bartman, was 
edited by Katharine Britton of the Editorial 
office. 
Acknowledgment is made to John W. Cad¬ 
bury, 3rd, Associate Curator of Insects, the 
Academy of Natural Sciences of Philadelphia, 
and to W. L. Brown, Jr., American Entomo¬ 
logical Society, for acting as consultants to 
assure accuracy of the text and illustrations. 
It must be emphasized that the habits, be¬ 
havior, castes, and activities described in this 
book are actually not those of any one species, 
but are combined in one here only to simplify 
and dramatize. 
Illustrations were prepared by Mary Procopio 
of the Pennsylvania Art Project, under the 
direction of Michael Gallagher.
